Worth Many Times Its Cost 
 
 A 'Live Paper, with New Ideas — Every Manufacturer and Mechanic Will Want It. 
 Bona Fide Guaranteed Circulation 23,000 Copies Monthly. 
 
 THE price cf Power and Transmission has been 
 made purposely low in order that the paper may 
 reach as large a number of subscribers as pos- 
 sible, and tiius extend its field of usefulness. 
 And as a special inducement we will send to each new subscriber 
 forwarding us $1.00, a 3-inch sample of a new method of joining 
 belts with a lacing or thong, which is worth to any manufacturer 
 or mechanic many times its cost. 
 
 Of this Ne'v Lacing Process, a prominent manufacturer says : 
 We have used this method on all our belting for years, and 
 find it the cheapest and best method we have ever seen tested. 
 We have one drive belt, 16 inches in width, stitched as above, 
 that has been running constantly for three years. Shows no signs 
 of weakness to this day. We have one drive belt, 30 inches, vide, 
 transmitting 150 horse-power, which has been running now 13 
 months, with same lacing, and never has been touched. It 
 eifectually prevents the annoyance of ragged ends to belting and 
 the restitching so common to other methods. 
 
 The Journal is issued monthly, and every number will con- 
 tain drawings and specificatio.is, illustrating the various ways that 
 power can be transmitted by ropes and wood pulleys, under the 
 Dodge Patent System. Send your subscriptions to the Dodg^e

 The Transmission of Power

 Ropes and the Dodge Patent Wood Pulleys 
 
 ♦ ♦ 
 
 r w ■%] 
 
 (HE great advantage of Wood over Iron as 
 a material for Belt Pulleys (or drums) to 
 transmit power economically, has induced the 
 Dodge Wood Split Pulley Co. to intro- 
 duce grooved hardwood pulleys for the special purpose of transmit- 
 ting power by ropes (Manilla tallow laid), and in this connection 
 Mr. Dodge has taken out Canadian Letters Patent for a system of 
 applying the ropes, adjusting the pulleys and taking up slack, that 
 i^ giving the most unciualified satisfaction. 
 
 This System of transmitting power by ropes is cheaper and 
 superior to belts in many cases, such as where the driven shaft is 
 at right angles with the driver, also where the drive is perpen- 
 dicular, particularly when it is quarter twist and perpendicular; 
 also where the driver and driven are close together ; also for long 
 drives, such as across a street or a stream, etc. For transmitting 
 the power from an engine to the line shaft this system is unequalled, 
 there is no slipping or jerking, the engine will run smooth and 
 
 steady all the time, not like a heavy belt, which is always more or 
 less flapping, jerking and stretching, then slipping and losing 
 power. It is safe to say that in engine hitched up by the Dodge 
 Rope System will do 25 per cen>. more work on the same con- 
 sumption of fuel than the same engine would do with a belt. In 
 this pamphlet we gi.'e four illustrations and commenting articles of 
 transmissions now in operation, ecdi one beii.g different from the 
 others, simply to illustrate some of the various situations to which 
 this system can be successfully applied, all selected frcm diflertnt 
 numbers of the Journal J'ower and Transmission. \\'e have put 
 up a number of the Dodge Patent Rope Transmissions during the 
 past year, all of which are in most successful and satisfactory opera- 
 tion, as certified by the testimonials following, of well known manu- 
 facturers that have them in use. Patties who are in want of anything 
 in vhis line or who arc interested in the efificient and economical 
 transmission of power are cordially invited to call at our Works, 
 81-89 Adelaide St. West, and see the repes and wood pulleys 
 in operation, as we are driving our whole factory by this system.

 'HK illustmtion, as shown opposite, is one of 
 [.'Lculiar construction, and represents an engine 
 transmission of power by a mnnilla rope, under 
 tile Dodge system of patents,'* and is shown as in 
 .ictual use at tlie worlcs of the Llodge Mfg. Co., at Mishawalca, Ind. 
 
 The system herewith illustrated and described is one of 
 great interest to all consumers of power. Inasmuch as it takes 
 the place of expensive gearing and broad bells, the* advantages 
 to be derived may be thus summarized : 
 
 'I'o transmit the same power with a rope versus a like power 
 with a wide belt, first, requires much narrower faced pulleys ; 
 confequently, much less expensive ; 2nd, the interest on the 
 money invested in a belt will more than supply the rope, say- 
 ing nothmg about the wear and tear ; 3rd, better power, from 
 the fact that all sliding of the belt is overcome, and the rope 
 gear becomes as positive as the cog gear. 
 
 The transmission consists of a series of wood split pulleys, 
 and an ordinary manilla rope (tallow laid). 
 
 The engine used is an automatic, and the size of the cylinder 
 is 18x40, making 90 RPM, and transmits 150 HP., the driver, 
 A, and driven, B, have each several grooves, in which are wound 
 the ropes, the nuinLier of wraps being used, as in previous cases, 
 to gain surface in contact, for adhesion of the rope. The winder, 
 C, in this case, is simply used to convey the rope to the slack 
 carriage, to prevent obstruction. This, together with the carriage 
 
 * Dodg.; Mfg. Co., Mishawaka, Inil., manufacturers. 
 
 pulley, I), are each single grooved. 'I"he device for taking care of 
 the slack, and giving the proper tension to the rope, is the same 
 as those illustrated in fuiiner issues ol I'ow i.K ANh Tkansmisskin, 
 and is shown at K, with the impelling weight at (1. The slack 
 side of the rope is paid directly from the driver to the carriage, 
 E, which, it will be seen, takes in and pa)s dut slack as it itcurs, 
 and acts also for a tension on the rope. The weight at ( I iray be 
 increased or decreased with the power, 
 
 This aparatus was ere< ted and started December 2, USN4, 
 and has been running constantly since, with same sjilice, and 
 transmitting an average of 1 50 H I'. 
 
 The rope shows no signs of wear, and looks as though it 
 would last for years to come. 
 
 The rope is an ordinary one iiuh diameter manilla, and 
 travels at a velocity of 3,420 FI'M, 
 
 We make the following summary : 
 
 Velocity of rope, 3,420 IT'M, Transmits, as above, 150 HP. 
 (indicated). The tension on the r()|)e is, therefore, -^^yVijVJi", = 
 1,408 + 106 pounds (one-half 'he weight in the weight-box) 
 = 1,608 pounds , which is the strain on the rope. There being 
 five pulling wraps of rope, hence the strain would be divided five 
 times ='-^ 321 lbs. .strain on the rope - 3" per cent, of the 
 breaking strain ; it being estimated as safe to use 10 per cent, of 
 the breaking strain of the rope. 
 
 [The breaking strain of a one-incli manilla roi)e is 9,000 
 pounds.] — Poiver and Transmission Joitniul.

 HE above illustration shows the Dodge system 
 of manilla roi)e transmission,* as in use at the 
 Stone (Quarries of Messrs. Boecker & Van- 
 Oven, of \apervillc, 111. 
 
 This cut represents a peculiar hook-up, and one which is 
 often met with in the transmission*of power. The drive pulley is 
 about fifteen feet lower than the driver, and being a perpendicular 
 shaft, makes a quarter turn. 
 
^

 This transmission was fretl«cl and started up in June, 1K86, 
 and has been running constantly ever sim c convoying the power, 
 25 HP., to drive a number six centrifugal pump, used for keejiing 
 the water out of the (juarries. A one half inch manilla mpe, 
 tallow-laid, is employed, travelling at a velocity o." 3,600 F I'M. 
 The rope is in prime condition. A,s to the satisfacti-jn given by 
 this transmissiim, note the letter from the Messrs. Boecker vV 
 VanOven elsewhere in this issue. 
 
 The transmission is a very simple one, and consi.-.ts of a 
 series of wood split pulleys, and an ordinary manilla tahow-laid 
 rope. The power is taken from a 25 HP. engine, makii g 300 
 RPM. Referring to the cut, A represents the driver, and if. 48" 
 diameter ; P., the driven, and is 24' diameter, located 15 teet 
 lower than the engine, and about 85 feel distant from the same. 
 The |)unip shaft is perpendicular, hence the pi.Uey runs horizon- 
 tally, and causes ihe rope to make a ([uarter turn. This is easily 
 accomplished by tipping the idlers or carriers DD, to get surface 
 in contact with the driver ; to get back on to the travelling car- 
 riage at F, the winder C is used. It will be noticed that the rojn; 
 passes twice around the driven and leads the slack rope directly 
 to the carriage, the slack being taken up at the driver end for 
 convenience. The weight used is 100 lbs., just sufficient to carry 
 u p the slack of the rope. The driver, driven, and the two carriers^ 
 1)1 ), have each two grooves ; the winder C, and carriage pulley, 
 K, have each one groove. 
 
 The device for taking care of the slack of the rope and giving 
 proper tension, is the same as those illustrated in Powf.r and 
 Transmis.sion, and is shown at F, and takes in and pays out 
 
 slack as it occurs fr(mi the slret( h of the rope, caused by atmos- 
 pheric changes. It also acts, by < hanging the weight, to increase 
 or diminish the power as retjuired. 
 
 We make up, from the above, the following mathematical 
 summary ; 
 
 Velocity of the rope, 3,600 I'PM., transmits, as above, 25 11 1'., 
 (estimated). The tension on the rope is, therefore, ' -jii^u^" = 229 
 lbs. + 50 lbs. (one-half the weight in the weight-box) - 279, 
 which is the strain on the rojie ; but there being two wraps, the 
 strain would be "5" = 139 lbs., and is about six per cent of the 
 breaking strain ; it being estimated as safe to use ten per <:ent. 
 of the breaking strain of the ro|ie, with this system. The breaking 
 strain of a h" manilla rope is estimattd at 2,250 pounds. — Pciar

 You will remember that we had to ajjj'ly the transmission in 
 a rather difficult position, as the driven ])ulley is situated about 
 1 5 feet lower than the driver, and makes a quarter turn, as the 
 pump shaft stands peqiendicular. The distance of the latter from 
 engine is about 85 feet. The A" rope used is a surprise to every-

 HE above illustration shows the Dodge system 
 of manilla rope transmission,* as in use at 
 the works of J. W. Dann Mfg. Co., at Colum- 
 bus, Ohio. 
 
 This cut represents a very handsome hook-up in the way of a 
 transmission of power. It is peculiar and one that is often met 
 with in practice, and demonstrates fully the i)racticability of the 
 system. That it may be fully understood and appreciated, we 
 give the following descripti on : 
 
ROIM*: I'RAXSMISSION— Fig. 13, continued 
 
 This transmission was erected and started u\) in 
 September 1886, and has been running constantly ever since, 
 conveyii " the power, (50 H. F.) to drive a line shaft on the 
 opposite side of a street. This shaft is on a parallel line with the 
 main line or power end. It became necessary to prevent obstruc- 
 tion in the street t(jgo back from the power end and up through the 
 upper stories of the main buMding over idlers, then across the 
 street into the uiiper story of the building where pcjwer is to be 
 used, then down again into tne lower story where is located the 
 <lriven shaft. 
 
 Now that this is desirable will be seen at a glance. The 
 transmission is a very iimple (jne and consists of a series of wood 
 sjjlit pulleys and an ordinary manilla tallow laid roi)e. 
 
 The power is taken from the main line, making 280 Rl'M. 
 Referring to the cut, A represents the driver and is 54" diameter, 
 with two grooves. B the driven is 61 i inches diameter, with two 
 L;rooves located as stated in a building on the ()])p()site side of the 
 street, about 125 feet from the driving end. The idlers I) are 
 •each 40" diameter and each has two grooves and the carriage 
 pulley is 36" diameter with one groove. 
 
 It will be noticed that the rope passes twice around the 
 ilriver and leads the slack rope up over the ca.riers and directly 
 imto the carriage ])ulley, the slack being taken up at the driving 
 <:nd for greater convenience ; will say however, that the slack 
 ■<;ould be cared for from the driven end as well. The weight used is 
 :2oo pounds, just sutificient to carry up the slack of the rope. The 
 
 device for takmg care of the slack of the rope and giving proper 
 tension is the same as those illustrated in former issues of PoJirr 
 nmt Trans III IS a ion, and is shown at F, and takes in and pays out 
 slack as it occurs from the stretch of the rope caused by atmns 
 pheric changes. It also acts by changing the weight to increa.se 
 or diminish the power as re(iuired. 
 
 We make the following mathematical summary : 
 
 Velocity of the rope, 4,000 FI'M., transmits 50 HP., (esti 
 m.ated). The tension on the rope is therefore — 'iH" '" ■■4n + "oo 
 lbs. (one-half the weight in the weight box) -511 lbs., which is 
 the strain on the rope ; but there being two wra|)s, the strain 
 would be »J' •» 256 lbs. and is about six per cent, of the breaking 
 strain; it being estimated as safe to use 10 i)er cent, of the 
 breaking strain of the rope with this system. The breaking strain 
 of a ^i^" manilla rope is estimated at 4,000 |)0unds. — Ptnver and

 O 
 
 UR illustration of Manilla Rope Transmission 
 for this month is one of great interest to all 
 manufacturers, inasmuch as it demonstrates 
 the simplicity with which a shaft may be 
 run at right angles to the driver and with little or no loss of power. 
 It is a well known fact, however, that with gears there is a great 
 loss of power from friction, and many other disagreeable points of 
 contention ; also with a belt and set of mule pulleys, there is a 
 great loss by imperfect contact of the belt with the pulleys, 
 journal friction, and other annoyances sufficient to condemn it. 
 On the contrary, with the Manilla Rope System, under the Dodge 
 Patents,* a shaft may be driven at right angles to another with 
 the same efficiency as two parallel shafts are ordinarily driven. 
 
 The right angle transmission consists of a series of Wood 
 Split i'uUeys with grooves for the ro|)e, .md an ordinary manilla 
 rope, (tallow laid.) 
 
 The power is taken from the main line which makes 250 
 RPM. and transmits about 20 HP. 
 
 The driver A and driven B, and mule pulleys CC each have 
 four grooves, and the carriage pulley 1) has one groove. It will 
 be noticed that the driver A and driven B act as winders, and the 
 rope is wound from one to the other to get surface in contact ; 
 the mule pulleys CC are simply carriers, carrying the rope around 
 the corner, and are so placed that the travelling carriage always 
 keeps the rope at an even tension, so that the rope:; will always 
 follow the grooves, and the rope is thus guided to and from the 
 driven, always keeping its allignment.

 The carriage above referred to, or device for taking care of 
 the slack and giving proper tension to the rope, is the same as 
 those illustrated in former issues oi Power and Transmission, and 
 is shown at E, with impelling weight at G ; the slack side of the 
 rope being paid directly from the driver to the travelling carriage, 
 leading back on to the driven. The tension weight serves a 
 double purpose, taking care of all slack caused from the stretch 
 of the rope or from atmospheric changes, and for a proper tension 
 on the rope. Should a change occur whereby more power should 
 be required, simply adding more weight would increase the power 
 in proport'on to the foot pounds carried, which multiplies with 
 the number of wraps used. 
 
 The merits of this system are its simplicity, great efficiency, 
 cheapnes,--. and wonderful saving in journal friction as compared 
 with gears (.r a heavy belt with mule pulleys. 
 
 This particular transmission has been running constantly for 
 4 months, and aever has given a minute's trouble. The rope 
 shows MO signs of wear and looks as though it would last for 
 years. The rope is an ordinary ^" diameter, and travelling at a 
 velocity of 3140 FPM, 
 
 We make the following mathematical summary : Velocity of 
 the rope 3140 FPM, transmits a? hove 20 HP. The tension on 
 the rope is therefore """ ""i;'" = 21 1 +30 pounds, (one-half the 
 weight in the weight box) equals 241 pounds, the total strain on 
 all the ropes ; there being 4 pulley ropes, hence the strain will be 
 divided 4 times, equals ^\^ equals 60 pounds, which is 3 per cent, 
 of the breaking strain of the rope : it being estimatv^d as safe to 
 use 10 per cent, of the breaking strain of the rope in practice, 
 with this system. 
 
 'l"he breaking strain of a |" manilla rope is 2250 pounds. —

 Dear Sirs,— In reply to jour enquiries as to how the rope transmission 
 (which you placed in our factory for driving machinery in picking room, &c.) 
 was working, we would say that it is giving us every satisfaction. Although 
 the work it is doing is heavy there seems to be no fri lion, and very little wear 
 anc lear of the rope and grooves.

 CiKN iLK.MF.N, — I havc much pleasure in stating that the I'.ope Tranr.- 
 mission put in my factory one year ago to transmit power from the engine ti' 
 the line shaft has proved very satisfactory, aii<l has run since then without a 
 fault. The Rope Transmission with which I supply power to the large factory 
 of .Messrs. Keith an<l Fitzsinimons and which you put in about two months 
 ago is also giving excellent service. This Transniis inn, which runs across 
 the street 150 feet, with the shafts running at right angles and in opposite 
 directions, is considered by experts t(j be the most ilifiicult piece of Rope 
 Transmission in the Domin'on. The third Transmission, which is conveying 
 power from the lower llat l(j the upper one, is also giving satisfaction. Com- 
 paring the way in which we were annoyed with breakages of the belt, whiili 
 runs at right angles, and the great strain on the shaft through the tightness of 
 the belt, with the ease with which the shafting is no« run by the Rope Trans- 
 mission, calls forth my highest praise of that system of transmitting power. 
 
 You are at liberty at any time to send parties to my factory to examine 
 same. 
 
 Yours truly,

 Gents,— We have much pleasure in testifying to the superiority of and 
 recommend to the public your system of transmitting power by Manilla Rope. 
 We think the motion more positive, and the transmission at least 25 % lighter 
 than Belts or Cears. We are using your system in our factory to run on line 
 shaft transmifing 25 Horse Power. With best wishes for your success.

 Gentlemen,— You desire me to report upon the set of pulleys pi>t in 
 one of the workshops to transmit power by a rojie to a counter shaft at right 
 angles, and I have pleasure in doing so. Pri«r to their having been p»t in by 
 you I had tirst used a two ply leather belt, 12 inches wide, of the best (|uality, 
 which only lasted a few weeks ; then I got a six-ply rubber one, same width, 
 made specially, and it also gave out in about a month, the trouble being th« 
 (juarter twist on short distance li«tween cgntres, ten feet, and the high rate of 
 .-peed called for. Your pulleys have now been in use over six months, »nd 
 with a ^ inch nianilla rope the full power required is transmitted steadily, and 
 with great regularity, since it does not slip, as the leather and rubber Ijclts 
 did, while very considerable power is saved. They h.ave realized lo the fall 
 all that was promised from them, to my «ntire satisfaction. 
 
 Yours respectfully, 
 
 JAMES MASSIE, Warden.

FOOD FOR THOUGHT 
 
 BY 
 
 :I 
 
 John Morley 
 
 think one of the most satisfactory tests as regards 
 
 the driving qualities of a belt over a wood or 
 
 iron pulley, was made at the J. A. McKinnon 
 
 Machinery Company's store, 22 Warren Street, 
 
 New York, recently. 
 
 An upright engine was used, on which was placed for a drive 
 an iron pulley, 42 "diameter, 10" face, driving onto a Dodge Wood 
 Split Pulley, 20" diameter of the same face as the iron pulley. 
 
 On this driven shaft was placed a Dodge Wood Split Pulley, 
 54' diameter, which became a driver for an electric light dynamo. 
 
 The test consisted in blocking the engine driving pulley with 
 a bar, and taking hold of the driving belt on the dynamo, keeping 
 the same in motion, together with the engine drive-belt (which 
 was strained up taut) ; but the belt slipped around the large iron 
 pulley, while it hugged the small wood pulley, without a percept- 
 ible slip at this point. 
 
 There was at least 70 per cent, more belt surface in contact 
 with the iron pulley than with the wood, which makes a practical 
 demonstration of the fact that a wood pulley will drive from 40 to 
 60 per cent, more machinery, with the same tension of belt, than 
 iron with like tension. 
 
 I will add that the iron pulley was in prime condition as to 
 face for belt drive. 
 
 This remarkable test is attracting a great deal of attention, 
 and it is well worth an investigation. Mr. McKinnon will at all 
 times be happy to demonstrate this experiment to those interested. 
 
 Such experiments effectually settle the fact that the use of 
 iron pulleys must soon become a thing of the past, and that wood 
 pulleys are as certain to take their place in all first-class 
 manufactories. 
 
 The Dodge Manufacturing Co., of Mishawaka, Indiana, have 
 been awarded the contract for equipping, throughout, the new 
 carriage factory of the Studebaker Bros., Manufacturing Co., 
 located on Michigan Avenue, Chicago, 111., with their patent 
 Independence Wood Si)lit Pulleys. They will also put in one of 
 the Dodge Rope Transmission Systems, to carry power from the 
 basement to the eighth floor. It will require over one hundred 
 pulleys for the new factory. As this will be the model carriage 
 repository and factory of the world, it speaks well for the merits of 
 the Dodge Wood S\)]\t Pulleys and their Rope Transmission 
 System. The Studebaker Brothers have also had large numbers 
 of these pulleys in use at their South Bend (Indiana) works for a 
 number of years.

 30 to 60 per cent, more power with same belt, with less Tension. 
 
 As less tension is required, the life of a belt is much longer when used on a wood pulley.

 With our system of Manilla Rope Transmission is overcome the objection to Wire Rope, 
 {because of crystalizing) and gearing, (because of loss of friction) and shafting, (because of the liability to 
 get out of alignment, hence loss of power by friction), and a separate engine plant, (because of its great 
 expense) ; on the contrary, with the Manilla Rope System, under the Dodge Patents, the power ''r, 
 transmitted with the same efficiency as though the shafts were close together, there being no loss of power 
 by excessive tension, or bad alignment, but simply the friction of the journals to ov(;rcome at the carriers, 
 which have a strain of weight of the rope to carry.
