The plate is :Made of t tae best quality omen hearth homogeneous flange steel of the most approved test for tensile strength, 1i~.it of elast i city, elonga- t ion , reduction n--,F7' area, a_^d trace of phosphorus. T'he fire box is constructed of the best quality fire box steel Dl~,Lte, strongly and closely stayed. The shell is triple riveted where side plates connect to shell, and double riveted elsewhere, and the fire box is stayed with crown bars. Large "nand .soles are su]palied both above and below the tubes, about the crown sheet and in the grater, legs, making the boiler thoroughly accessible for cleaning. TEST Boiler tested to 250 77,s . by-d_r_ ostatic pressure and guaranteed perfectly tight. ENGINE To be f~ rnished with double cylinders 5-5/811 x 9" stroke, made in one casting, which inclines bored crosshead glides (insuring perfect alignment) and the valve chambers. The space between the cylinders forms the steam. done. The throttle valve and gov- ernor are located on top of the dome, slaking only three face joints in the entire arrangements which reduces the possibility of leaking and necessity of repair to a minirnum. The double cylinder avoids the possibility of the engine stopping on :the center, is always ready to start the machine and equall.ze the strain on the countershafts Rnd connecting parts.

SPrEDS The roller is arranged to travel at tr. o ,),I us, I by simply shifting a lever the speed is changed from fast to slom or vice ver;:;a. GEARS The teeth of the crank srlaft yDinion and of the first countershaft gears are all machine cut, Making a w ooth and noiseless running machine. The gears are all of large (.iameter and wide face to insure longevity. The gears are made of s--)ecial I oMo,:;eneo~ . steel, ex-.: .6 for our rollers, and, they areDrotected by dust covers and rirovided 7ith self oiling box.es.

PICKS 7Te furnish a full set of forged steel and tempered ,picks. The Achy are fitted? out into tapered and reared holes in the driving 7heels. Accurately fitted plug: are provided for filling u.,) holes in driving Theels ~hen Dicks are not in use. YOKE The front carriage is su;.jported by open hearth cast ;steel yoke, cast in one :'i.ece a construction 7ith no joints to 7ork loose and avoiding the tendency to break;: ge of the cast iron yoke. GOVER?,1OR We furnish a Picl,erin Governor to regulate 4U-I s~Deer' of the en; ine, and the governor is absolute- ly necessary :Mien the engine is used to drive the stone crusher or other machinery. CRANK SHAFT sf'e furnish a forged cram, 2-7/8 inches in diameter su,)ported by center bearings and constructed to take up lateral thrust ;*it1j.-out causing strain rue to expansion of boiler. C ONNECT ING RODS Made of fine grade of steel, fitted with gun metal boxes, easily adapted for wear and all parts of the most appro ed designs and dimenai-ons. B-OXLS The main pedestal boxes are very large in diameter also in length, made of phoaphorus bronze. All boxes so arranged as-to be easily removed. GENERAL REMARKS All of our rollers are furnished and fitted-with all our modern improvti meets and in the general construction we take s,?ecial pride. We have spared neither pains nor money to Xe our rollers complete and perfect. Inspeotion of 'our rollers will show that in all the details that go to make up a first- -lass machine, our roller is unequalled. a We call special attention to the convenience of all the working puts which are arranged so that they can be easily gotten at either for oiling or adjusting. All rollers are thoroughly and com- pletely tested in every part of the apparatus. BUFFALO PITTS COMPANY. .
