 WHAT RAILWAY BALLAST MAKERP SAY OF THE GATES BREAKER. 
 
 „ , Choate, Del., Feb. 14, 1888. 
 
 Gentlemen:— \oms of the gth inst. received. We t.ike pleasure in 
 giving our testimony as to the superiority ol your Breaker over all 
 others. We have used no otiier, but have seen them and know their 
 capacities and weak points, and have had positive proof of their 
 inferiority to Gates' machir.. We know that our stone could not be 
 broken into ballast by any other machine; that is, continuously, ow- 
 ing to its great hardness. 
 
 We consider your claims for it entirely reasonable, as we have 
 found the machine able to do more work, break more stone than 
 we were able to deliver to it in any one whole day. 
 
 The repairs have been very reasonable, considering the amount 
 and character of work done, and much less than other machines, 
 which we learn from others using them. We positively think it the 
 greatest machine on earth for the puriwse, and have a very enthusi- 
 astic opinion of it. Youts truly,

 Dear Sti-s:~\n reply to yours of the 25th inst., would say fhat the 
 Gates Breaker gives us satisfaction. We have three Breakers, one 
 Size 3 and two Size 7. With our plant we can break 90 cars in 
 lo hours. I cannot say how long the concaves will last. Our 
 Breaker we have run for hoo years, and have not spent a cent for 
 repairs, and I think the concaves are good for hit years more. Our 
 stone is very hard limestone. I expect to break 7,(xx) cars of bal- 
 last this summer, and I would not give a man one dollar to guarantee 
 the expense of the Breakers, outside of oil. I took a gentleman to 
 see one of ours last week; the weather was cold; he timed 4 cars in 
 42 minutes; they weighed I56,oo(i pounds.

 Port Chester, N. Y., Feb. 20, 1888. 
 Dear Sirs:—'^t have been working from six to ten Rock Breakers 
 for the last fifteen yet s. Among those used were three from the 
 Gates Iron Works of Chicago (one Size 3, one Size 4, and one Size 
 6). We have no hesitan;y in saying the "Gate;, Rock Breaker" is 
 far superior to all others. It hasevery advanti.ge. ist. In quantity 
 of stone broken, about three times as much as in a flat jaw breaker. 
 2d. In uniformity of size of stone broken, no spalls or flat pieces. 
 3d. A saving of from 30 to 40 per cent, of power by actual tests. 
 4th. A saving of from 25 to 50 per cent, to keep in repair. 5th. The 
 continuous discharge prevents packing or pulverizing. We could 
 enumerate many more advantages your Breaker possesses, and to 
 sum it up will say, your machine is entitled to all you claim for it. 
 Very respectfully, 
 
 CARPENTER BROS. 
 
 Alton, III., Feb. 11, 1888. 
 Deat Sirs: — You ask me what I think of your Breaker. I have 
 used one of your Size 6 Breakers since 1881, and consider it, as you 
 claim for it, "The Best on Earth." In fact, would not use any other. 
 I am breaking 25 carloads of stone ballast daily, the cars averaging 
 30,000 lbs. to the car. Our stone is a hard limestone. The repairs 
 have been very li;^ht during the seven yews it has been running. So 
 can cheerfully recommend your Breaker as being the best made. 
 Vours respectfully,

 Gents:— y^c used the first Breakers made by you of each of three 
 different sized patterns. After several years' service breaking 100 to 
 1 50 tOiis of stone per day with the large machine, and less than five 
 dollars per year for repairs, the Jiieakcr is as good to-day as wlien it 
 came from the shop. I think it is the best Breaker that I have ever 
 seen, and think there can be nothing better. We are all well satis- 
 fied with it. Most respectfully yours,

 fully in favor of the dates P.reaker. The eight or ten breakers we 
 have sold have, without exception, given satisfaction, and as to re- 
 pairs, we have not ordered two hundred dollars worth of repairs in 
 five years. One of our largest customers says, if any one wants a 
 breaker and does not buy a dates, he simply docs not know his busi-

 Gentlemen :—^\\e bought of your house a Size 3 ISreaker, and sub- 
 sequently bought a Size 6, which we have now been running almost 
 constantly for four years, breaking limestone for Macadam, It gives 
 
 us pleasure to indorse your Breaker as all and more than you claim 
 for it. We have practically h.id nf) repairs in the entire time the 
 Breaker has been running. We can break a ton of Macadam or or- 
 dinary road metal a minute in it, when able to get the stone to it It 
 will take in stone 11 by 24 in each of three f)pcnings. 
 
 In short, it breaks more stone, takes less power and less repairs 
 than you allow for it in your cat.-.logue. 'I'lie result of ycarsof expe- 
 rience has convinced us that your Kock Bre.iker has no e(iual. The 
 latest patterns of Jaw Breakers cannot compete with your ISreaker, 
 each receiving and discharging the same sized stone. The secret of 
 your advantage lies in !he mechanical f.ict that there is no lost time 
 with your Breaker, /t is constantly fireai-ini;. Vour devices for oil- 
 ing, the perfection of your journals, the simplicity of design and lack 
 of parts, are all mechanical points of the highest excellence. Your 
 Breaker does not require experienced machinists for running it. The 
 shape of the breaking surfaces produces the most perfect cubes for 
 road metal obtainable. It is the only form of breaker that will meet 
 the requirements of contracts in this city, where grsat attention is 
 given to size and shape of product. In fact, we know th.-it no other 
 Breaker is used for road metal in this city, where the consumption of 
 granite and limestone macadam has grown to enormous proportions. 
 Respectfully yours,

 e.xcel all breakers we have yet used. On an average we break 1 50 
 cubic yards of liver bowlders per day of ten hours, with each breaker. 
 Same have been in constant operation for three years, and we never 
 had any occasion for expense, worth mentioning, in having same 
 repaired. In fact, they are all you reprcsente'l them to be.

 In reply, the Clates Breaker is all that can be desired, and in fact I 
 consider it the best and most durable Breaker now in use, and it will 
 certainly do tnore good work than any lioo other Breakers I ever saw. 
 I have used many different Rock Breakers, but have abandoned all but 
 the Gates, and have at this time six in use. A head and good con- 
 caves will run from six months to one year without change.

 Gentlemen: — Having had some five years' experience with Rock 
 Breakers, I wish to say that I think your Size 3 Rock Mreaker. 
 owned by Mr. ^V. K. Duttield, and setup and run by myself, li.as 
 the champion record of the world. November 3, 18S7, we broke 
 and screened 200 yards of rock fot concrete, largest size to go 
 through a 2% in. ring. 150 to 175 yards was an easy day's work, 10 
 hours. Gray limestone was the kind we were working. We have a 
 30 I. II. 1". engine, and run the Ijreaker 500 revolutions. Never had 
 a hot box, or any .accident or breakage. If there is any Breaker 
 same size (Size 3) that can do any better than this, please let me 
 know; I would like to see it. I am.

 CALEDONIA (;OLD MINE. 
 
 T,;rravii.i,b, I). T.. Sept. 24, 1888. 
 
 Gcntknien: — Voiir favor of the 4th inst. .it h.-imt and contents 
 noted. We have one .Size 6 (l.-itcs. With a fx) stamp n'iil, this 
 saved us in labor, power, cjc., some 1^27 .a day. With an 80 stamp 
 mill (wliich we now have) I calculate about !|!3<) to 1^35 a day. 
 
 We were usinjj I Slake breakers No. 6, receivinjf openinj^s 9x15 
 inches. I'Or an Ho stamp mill it reciuires 4 Ulakes, requiriiijr 3 nien, 
 e.ach u hour shift, to feed tliem. 'Hie lilake action is not continu- 
 ous; half the time is lost in the Ixickward action. We ran the iJl.ikc 
 I'.reakers nij^ht and day to keep the mill supplied. The dates 
 Breaker has three reieivin^j openin(js, capable of receiving 11x22 
 inches. Our ore is very hard; the larjjer the receiving openings of 
 the lireaker are, the less labor we require to break up the rock in the 
 mine. This saves us 3 men in the mine. 
 
 We run through the ( lates lireaker 2()o tons of ore in 1 1 hours with 
 two men feeding. Thus we supply the broken stone for the entire 
 mill for 24 hours by running the dates lireaker one shift of 1 1 hours, 
 or running the lireaker during the day, and shutting it down at 
 night. This is a saving of four men. lly this means I am enableil 
 to lay off all laborers at night in the mine; do no hoisting of rock at 
 night, and save the power of the lireaker. the wear f)f machinery, 
 etc., and do the greater portion of my work during the day. This is 
 an advantage. 
 
 The action of the O.ates is continuous and direct. We could easily 
 break with this lireaker 50 tons more of ore during the same time. 
 For this lireaker we use about 35 or 40 Iiorse power. The lireaker 
 has a hopper so the ore does not have to be shoveled into it, but is 
 dumped on it, and for the greater part falls into the openings. 
 
 The wear of the concaves and head is not gre.iter than the wear of 
 wearing parts in other breakers. Our ore is so very hard that the 
 wearing of these parts here is hardly a criterion. We replace the 
 concaves every six weeks, and the head every two months. The 
 Breaker can be set up to break the ore to any degree of fineness 
 required. 
 
 1 am highly pleased with the Breaker, and consider it the greatest 
 improvement made for years in this class of mining machinery. 
 
 Any other infortiiation I can give yiu, I will be pleased to do. 
 Very respectfully, 
 
 T. L. .SKINNER,

 Size 2 dates lireaker at the Ropes (lold anil Silver Co.'s mill, would 
 say we have been running the lireaker continuously for the past four 
 months on very hard (pKiitz, breaking 50 to 60 tons per dry; and as 
 to the working of the machine, would say I consider it far superior 
 to the lilake, having used both here. .As to wear, the chilled iron 
 surfaces last about twice as long .as in the Blake, and break the 
 quartz to a more uniform size for the stamps, which we find a great 
 advantage. ,My only regret is that we did not get a larger Breaker, 
 thereby saving the amount of sledging to be done.

 In reply would say it works well, I am well satisfied with it, and 
 from the experience I have had with Rock Breakers I consider this 
 the only machine I ever saw that is worthy the name of a Rock 
 Breaker. There have been a number of parties in to see it who in- 
 tend to get Breakers this fa^l or next spring, ami all are delighted 
 with It. Yours respectfully,

 Dear Sirs: — In reply to your incpiiries in relatioi. to the Rock 
 Breaker you put up at this mine last fall for exhibition, would say as 
 follows: We have used it several times and broke from 150 to 200 
 tons ot riek copper rock with it. Some of the rock broken contained 
 from 15 to 3!; per cent, of copper, all of which passed through it as 
 easily as if it was only quartz, or hard amygdaloid rock. The ma- 
 chine is doubtless rightly named, "The dreatest Rock Breaker on 
 Earth." I am fully satisfied that it is far superior to. anything of the 
 kind now in use on Lake Superior.

 tensive experience with your 'dates lireaker," 1 consider it the best 
 in the market for breaking ores.

 Gentlemen: — Vou ask my opinion of your Rock lireaker's capacity, 
 durability, etc. .Mthough we have the smallest size, its capacity has 
 always exceeded our wants. We have this day been breaking diamond 
 quartz, as hard as any in the Rockies, .Tn<l my only si'rprise is that 
 the macliine is not liroken. I regret we did not order a larger size. 
 Us operations so far have been satisfactory, and I, with confidence 
 and pleasure, recommend it to any in want of Rock Breakers. 
 Yours respectfully,

 Manager Santa Clara Mining Co, 
 

 
 Fig. 37 represents the Plant of the Cambria Iron Works, erected at Birmingham, Pennsylvania. This 
 Breaker is our size 8, the largest we build. The letter of Mr. John Fulton, the General Manager, will convince 
 any one of the merits of this mammoth machine.

 Dear Sirs: Your favor of October 31st received. I visited the P.irmingham Limestone Quarries of the 
 Cambria Iron Company yesterday, and found the large Breaker (tlic riinstodt)u of its class) working with the 
 utmost ease. The machine is breaking 500 tons per day, which appears to be less than one-half the work of this 
 powerful Breaker. We are extending the quarries to get the product up to 700 or 1,000 tons per day. The 
 Breaker does its work very easily, and we estimate that when we get up to 700 tons per day it will cost us about 
 two cents per ton to break the rock. The limestone at this point is rather tough, and requires more force to 
 break it than the limestone near your city of Chicago. 
 
 I may say that we are very much gratified with the results of this large Breaker. You will remember thai, 
 when Mr. Stackhouse and the writer accompanied you out to the limestone (piarry south of your city, we saw, I 
 think, two or three men keeping tiie Breaker open, and it was for this reason that a larger Breaker was suggested. 
 Its economical working shows the wisdom of this increase in its capacity, and I am not sure that you will not be 
 urged to make a larger one still. 
 
 A number of persons have been down to see this P.reaker at work, and they all return entirely satisfied as 
 regards its ability to do what is claimed for it. Without urging it very fast, it will break two tons per minute 
 readily. I think any reference that may come will receive full satisfaction in every respect in regard to the 
 capacity and economy of the machine. Very respectfully,
