I '■ THE ■ . BALL Dynamo ^l 1 TAS been condemned by theoretical electricians 9^ IJ. in the years gone by as an electrical absurdity, ' and contrary to the laws of electroklynamic generation ; but it has been spoken of by parties using it, and others familiar with it, as the best arc dynamo ever constructed. In later years its opponents have admitted " It is a good dynamo, but wrong in principle. Its merits aVe in superior material, workmanship and skill." You may have heard of its reputation, its durability and freedom from repairs, and may doubt whether it has the merits claimed for it, or is intrinsically wrong ; and may ques- tion if its existence fpr the past six years with a business each year n^ore than doubling that of the year previous, is due alone to superior workmanship and material. To remove such doubt, if it exists, the Ball Electric Light Company submit for your consideration the following practical, electrical and mechanical reasons why the Ball Dynamo has a greater economy, greater durability^, greater reliability, and greater freedom from break-downft than any other dyndmo made. * I. Economy. — It is made of -wrought iron, end frames, bars and poles (a feature 6f\the Ball Dynamo alone, and covered by patents), anct admitted by all electricians to be the proper construcSon to. obtain the most economical field. 2.' The poles are widely separated, an4 there issno leakage of lines of force from wing to wing of poles as there is in all other dynamos. 3. A bar of iron of a field magnet is nearly satura^ as it approaches its poles. The lines of force have a tendency to escape and close thrpugh air. In the Ball Dynamot^as can be seen from above design, each armature :V- I % t. takes any loss of magnetic force that was intended for the other armature. 4. ^ l^e mechanical; parts for holding the commutator and driiring armature, are constrQcted of gun metal, and aflbrd no passage-way for the magnetic lines of force other than through thft cores of the armature. 5. These mechanical details are so Constructed as to form no closed loops or large masses of .metal for gener- ation of waste or Foucault currents — a feature peculiar to the Ball machine, and covered by patents. " 6. By taking a given w^ght of wire ancUpreading it over two cores, as in the Ba|l I)ynamo, instead of over • one c'ore, as in all other dVnamos, the iron of each armature is brought much nearfcr the pole pieces than is possible with single armature machin^i's, and the average distance oPthe copper wire from the ^les is much less l hence, a greater output from the Ball than from any single armature machine. ' ,;^. 7- When a given amount of copper yire is wound on two cores instead of one, the average distance of wire to core is less, and the wire is wound with greater economy. A given length of wire will give two cores^ 5% more con- voflutions than it will on onej hence, an^ additional output of 15%. • ' 8. Very Small Los^ from Waste or Foucault Currents. — With a given field exciting two armatures, U is evident that each armature cuts the l|nes of force of but onehall of this field, and that'll local E. M..F. tending to produce waste or Foucault currents in each small cross section of its core revolving before this field, is but half of what it would, be were this core revolving before the whole power of the field. This being so, the waste or Foucalilt current generated therein must be but one-half, and the heat or lost energy resulting therefrom (C* R) must be but one-quarter ; and as we have two armatures, the heat and energy lost in both from Foucault currents will be but half that of a similar core revolving before both poles or full field. 9. Economy from Mechanical Reasons.— No work of friction. The Ball machine is so constructed that the force of pull of belt, magnetic pull of armatures by pole, and the force of gravity, balance ^nd neutralize each other. This can be seen by reference to the cut of the machine. The pull-up pf the belt being balanced by the weight of armature, and on the other end of the machine the weight of the armature is balanced by the attraction of the top pole. \ ; , / I ■ ■ ■ ■ 10. Reasons for the Great Durability.-^As~ explained in Section 6, we have in our armature double the radiating surface for the simic amount of heat given off, and but one-half as much insulated wire around thit core, aflbrding a quick passage for the heat froii;i core to surface. Also, the heat in core from Foucault currents is but one-quarter that in the same core before bi-[X)lar field. We ktmo from our experience during the fast six years, that absolutely tto deterioration .takes place from long and continuous use. This is a point on which our comijetitors are dumb ; and when their armatures give out after from two to five thousand hours of hard usage, they explain matters by saying that_/the Dynamo has been over speeded or that the circuit has some time probably been struck by lightning, but Jupiter in his wrath, overlooks the Ball Dynamo. 11. Reasons for its Reliability and Fi^edom from Break-downs. — The Ball system is the only one u|iing the pure and simple Gramme armature. An endless iron ring entirely surrounded and covered by an endless coil of insulated copper wire— the best high- tension armature made. It is impossible with this armature to be troubled by its striking through or burning to the core, as the core is electrically connected with nothing, and protected for all time by its continuous and solid surrounding of insulated copper wire from having its insulation alTected by dust or moisture. 12. The Ball machine has two armatuires. Each armature raises the' tension il&rtjarf of the full machine. Therefore there exiswUw our armature but ' one-half the tension of that on armatures of arty other dynamo of corresponding power, and it is subj&ted to but one-half pf the electrical strain. ' 13. Our dynamo is coupled with the armatures as terminals, and the field circuit between them. By this method it is impossible for the field or any part of the dynamo to be subjected to more. than one-half of the tension of the machine, and, as from Section 1 1 it is impossible for the core to become electrically connected with frame of machine, our field is practically subjected to' the tension of its own resistance only. On other dynamos the field is subjected to full tension of the machine. * *; ^ ■ ! ■■■■ , iWSS-. ^ Wm, •,V I Showing what Ball Dynamos can and are doing under difficult cireum- stances; Croton Aqueduct, New York City.-Circuits ' underground in wet shaft* or tunnels in process of con- struction—dynamos run to their fuU capacity day and night, continual daily shifting of lines and lamps to per- mit blasting, and frequent grounding and short circuiting of wires.

At Shaft No. 16, operated by Denton, Breuchaud & Co., we have a lo-light dynamo in operation since May, 1885 ;^as run^ 26,200 hours; runs on an average 14 to 15 lamps ; has a record of 34 continuous days and nights withotit a drop of current ■^ At Shafts Nos. 18 and 19, Paige, Carey & Co., we have two 10-light dynamds.

It is the purpose of the incorporators to make this a model plant, which will vividly illustrate the ad^htaee which the Ball i.oocrcandle power light has over the a.ooo candUe power light for street purposes. A greater difiiision of light has Jong been demanded by the interested public, and the fact is frist becoming established that this object can be accomplished only by I .!!"»*'(. o* '°" *™P*"' '•«* *=»"<"« Poww Jamps as furnished by the Ball System. \ [ . '1- .. $1 \ ■ ■. 1 s • si?'! 1;.., . t1 THE Ball system OF ELECTfllC LIGHTING A Few Mechanical ahd Electrical Facts Regarding It ^ The important factor in all systems of electric lighting is the Dynamo, or Current Generating Machine. These machines are all based upon the^same general principle ; all generate currents in the same manner, and with the single exception of the Ball Dynamo, all machihes*bear a striking resemblance to each other in the essential elements of their construction, the current being generated in one armature, which is rotated within the inductive influence of both the poles of a powerful electro-magnet ^. *" BALL ARMATURE (Patented). The Ball Dynamo has two armatures, each being rotated within the influence of the separate poles of an electro-magnet. This, construction has been proved to possess great merit, and the Ball Dynamo is constructed with less material^ has less internal resistance, has greater efficiency, generates less heat, and to give equal results requires less pmver than any other dyixamo in the world. . The greatest difficulty with which, electricians have ' to contend in the construction and operation of electric current generators, is the electrical heat developed by the current within the coils and armatures of the machines, which chars the material with which the wires are covered, and destroys the insulation. The^BALL Dynamo does not heat. END VlftW BALL AIUCATURB.

It will be readily seen that there can be no loosening or shifting of the mounting device, and consequently no injury to the' insulation o'f the wires of the armature, either from vibration (and consequent breaking of connections), or scraping or crushing the wires out of position as would ensue from any other mounting device, such as a cone with wedges, wfiich would be tightened by the pull of belt on shaft and as readily loosened if the rotation of dynamo should be reversed, as frequentljrjj^pens where dynamos are run in couples. Sucya mounting device as this last we used on an experimental dynamo, but abandoned it as it was without merit We^ notice that an opposition company have resurrected it. ball commutator. (CoiMtraction Patented) The Ball Commutator is composed of a> number of pure copper sections, separated and insulated one from the other by thick strips ofmtca. u y The pins or arms connecting segments to armature are thoroughly insulated, the interstices being filled with the best insulating webbing or filling. Every alternate pin is offset This ad mits of making both armature and commutator of a much larger number of sectidhs, ahd this number is doubled by using two armatures, and, therefore, the current generated by the Ball dynamo is as steady and constant z% can be produced from a dynamo electric machine. Our 40-light dynamo has 308 sections in both armatures, and this number multiplied by i,aoo, the number of revolutions of shaft p^ minute, gives 369,600 increments of the current into the circuit per minute, or 6,160 per second. FRAME OF BALL DYNAMO. The only dynamo frame constructed of wrought iron throughout. End plates, pole blocks and magnet bars are made from softest, special wrought iron, forged to shape, surface ground and highly" finished. All joints of frame have scraped and polished bearing surfaces, and therefore there is no loss of magnetism at these points. . — .-— Why do we use an expensive wrought iron frame, while most other makers use a cheap cast JFrame more easily constructed and fitted? Simply because the magnetic conducting power of best wrought iron is 18, as compared with the magnetic conducting power of cast iron, which is onl/ 10 ; 1. ft, a dynamo constructed of wrought iron is 80 percent, more effective than- a dynamo constructed from any equal mass of cast iron. Results : Our dynamos are lighter and stronger ; will run with less power because we require 50 to 80 per cent less copper wire on our machine than other systems require to do equal work. Will also run with less heat. -10- , COMMUTATOB HUB. ing erection, furnished upon receiving plan of building, showing location and number of lamps reauired Our Incandescent dynamo has the same advantages over other Incandescent dynamos that our Arc has over other Arc dynamos.

We are more than pleased with your system of InG|indescent Electric Lighting. It has Worked perfectly from the , start— no alterations nor repairs whatever. Our engineer handles the entire plant as easily ai though he were an electrician. Gas is not to be considered with it. We not only giet very much better illumination at less cost, but the sanitary condition of our roon^s is so much improved that our help can work with as much comfort by night as by day. We hesitated for some time about putting in the electric light from fear of our in;>bility to handle it, but considering the simplicity of your system it was comfor and money Jost.

San Francisco, July 24th, 1888. Ball Electric Light Co. Gentlemen, We have been running two of your 25-light, 1,000 nominal c. p. (or 800 actual & p.) dynamos at Napa City, Cal., since the commencement of the year. About/ 30 of the lights are used for street illumination, the balance for private use. During this time the expense incurred for repairs has not been one cent. The light is\ pure white, does not hiss and is fuUy the equal in stead- iness of the very best systems of Arc lighting upon this, coast We believe that the volume of light given from our 800 c. p. lamps is in excess of that c. p. ; and we have the opinion of several of the most prominent electricians in the State, that the Ball 800 c. p. lamp equals in illuminating power the so-called 1.600 and 2,000 c p. lamps of other systems. Our cu^^ers and ourselves are much pleased with the light. ^^. Respectfully yours, West Coast Elec|ric Light and Construction Co., JOHN LLOYD, Sec -17- I! *. Providence, R.I., July 25th, 1888. BalJ Electric Light Co. * Gentlemen, We have in u^ one 3^-irght machine which you furnished us in the\sprin£ 6f 1885, and one 70-light machine which you Vurnished us in the fall of 1^87. The 3S-light machine\is 1,200 c. p., and the 70-light machine is 800 c. p. ( In regard to the ruhning of these machines, it is fair to state that the repairs On them since we have owned them have been practically nothing. We consider that we liiake a large saving ih the expense of running, on account of their taking l^ss power than soine other makes, and on the whole ^-e think l|iat the lamps give the steadiest light that ,we' have. Forty-one of the lights on the 70-light machine took the place of what were or^inally 2,000 c. p. lights, and we did not iigi placing them increase the number of lights at all, so :^hat we are now lighting^he ss^me space with forty-one 800 c. p. lights as we formerly did with forty- ^one 2,000 c. p. We have no hesitation whatever ii^ recominendirig your system, and consider it iirst-class in every respect, and should we need any-further itiachinery in this line, we should certainly correspond with you.

Our firsf 75-light a.ooo c. p. Ball dynamo we have had in constant use since October, 1887, and the secpnd do., was started December 20th, 1,888, and was put in upon the recommendation of the first. - These dynam^ have had little or no attention, and did not seem to*^' require any* They have run contii^uously everyVVitght — the first in commercial lights; the second in street lamps — without one serious interruption. The lights are brilliant and without a waver : in fact, for steadiness we have never seen their equal. Our conclusions are, that in our experience and knowledge, we knew of no Arc light system that for general utility, nijnimum of cost for repairs, lack of cdre and attention r^^pled, and for brilliancy and steadiness ofiight", can cmtpare with jthe Ball system.

They have no dead\centers. The motors vary in their ^onstniction to meet the requirements of the different electrid circuits. It is necessary to know the character of theLelfi&tric cireuit form which i^ is to be operated. If arci the current in .^amperes ; if the circuit be incandesctent^ its rated >umber of volts jtnust be stated. With ^his informa- ^ tion a motor can be provided of the size ahd with the attachments which the work to be done requires. The regulation of oUr motors is practically perfect. ^ In the incandescent motors, owing to the careful pro- . portioning of the resistance of field magnets and armature, scarcely any variation in speed is noticeable - between full and light load, and this regulation improves in the larger sizes. The arc motors are the best governed and most economical on the market. In writing, state nature of work required of the motor and probable amount of power needed, 'also ■ character of the electric ligltt circuit.' We build several different design.s, sonie with one and some with two armatures.

It requires no cooling, regulating or safety devices whatever. It will <7?///(7j/ any other Dynamo, as the normal heat generated within it is much less, and ii\ore readily radiated. It does not requife to bo run at an exact speed, and any power of ordinary uniformity will produce good results. // is the only Dynamo that will not overheat when subjected to the variable speed cf engines used in miffs, fac- tories, etc. Over- speeding does not affect it. '^ It does not require the attendance of an expert, but any intelligent man can quickly be taught to operate it with success. It has made the longest continuous runs of any 1 )ynamo yet constructed without heating. It has been in practical operation for six years, and has been subjected to more severe tests thali any other machine in the market. It has extraordinary efiSciency.f'and leaves but little, if any, room for improvement In electrical generation by induction. '< Its mechanical construction -'is of the best. The shaft is hammered steel, ground to standard si^e, the bearings gun metal, the frame forgejd iron, surface ground and finished bright. The workmanship will bear the closest inspection. The wear of commutators and con- sumption of brush copper is very slight. It requires but two-thirds of one horse-power to pro- duce each full arc light of ^,000 nominal candle-power. It requires but two-thirds of the power r equired by all other Dynamos made in Canada or United States to produce an equal amount of light. T It is equivalent to two Dynamos of any olher make, for the reason that if one armature is disabled by acci- dent, the other armature will maintain nearly three-fourths of the full number of lights. It will give more perfect results with less skilled . attendance than any other Dynamo: ^ It can operate arc or incandescent tights separately, or both in combination, in one circuit, or in two separate -cigcuit&,-at-thc~«ame time. - - — - O s < z > 8 III § 3 Z ■ o p. < h < Ifa h s u O E CL &3 a, \ %%% 8'8 8 8 10 ,t~ C6 iH 10 09 -mspH i?' ? ?> 2 n s 1»PIA\ « ?a m ^ 00 'mauoq o n CO «, « eff n j^ ^ 00000 o-o g CO « 00 a a e Q 10 10 ^ <$ a CO po^s*»i8a% ■'""' "'^-^ ■•*■• 0O3's liaaaiSuis rt CT (M CO « CO 10 JOMIPIAV •OOIBU.tfl JO xoitiia v» J3MOc] 98JOH •d 91 CO CD (D C9 10 10 CO <-l rH rH CT •it 2 2 55 S '*' * o ^ O 00 C^ iH 10 10 '^ « »H ^ (« »H m CO r- 'SiMaduiv ^ 00 ^ 00 O •s^lOA }0 joqinnx 8 ^ 8 S -^ S ?
