THE NEW 



SHARPIES 



Suction Feed Tubular Cream Separator 



Purdue University officials estimated recently, after an extensive investigation, that 

 the farmers of the United States were probably losing $100,000,000 per year in butter fat 

 by turning their cream separators at improper speed. Another test made by a company 

 which manufactures speed indicators for cream separators and other purposes showed 

 that out of 40,000 men and boys who tried to operate cream separators at proper speed, 

 95 per cent, failed to do so. The combined losses of all cream separator users operating 

 their machines at randon would average $104 per separator annually. The importance, 

 therefore, of the new Sharpies Suctioa-feed Tutoular Cream Separator may readily be ap- 

 preciated when it is said that this new machine eliminates every one of the undesirable 

 weakness heretofore found in cream separators as a class. This new suction-feed separa- 

 tor skims just as clean at 35 turns per minute or at 55 as it does at the normal speed of 

 45 turns. The only difference that speed of operation makes is to increase the capacity of the 

 separator. When time presses, the operator of a new Sharpies can speed up the new Sharpies 

 to 55 or 60 turns and he immediately has a separator of one-third greater capacity than he 

 paid for, and which will do the work in one-third less time. The new Sharpies not only sepa- 

 rates thoroughly, but it also produces cream of uniform density at every speed. These three 

 features are of prime importance, both to the dairyman who keeps three cows and the one 

 who keeps 300. 28 new features in all. The entire construction of this new Sharpies machine 

 has been extremely simplified. It is convenient and durable. The Tubular bowl is suspended 

 by means of a flexible steel spindle from a single bearing. A hardened steel cone holds the 

 weight of the bowl while it revolves on the balls. No parts slide. It is therefore almost frlctionless. Heat or cold cannot 

 cause expansion or contraction. The bearing of the new Sharpies is at top. The Tubular bowl hangs from this bearing natur- 

 ally. The three-piece bowl is light, steel tube, hollow throughout, and contains neither discs or other inside parts. It is 

 therefore easy to clean and keep clean. In the new Sharpies the bowl is driven by strong, simple, direct, self-oiling gears 

 enclosed in a case to protect them from dust and grit. The gears run in a spray of oil constantly. There are no oil cups, oil 

 holes or drip shelves on the Sharpies. Gumming is impossible. The heavy, one-piece frame has neither shelves nor legs to 

 work loose or snap off. The supply can is the largest used on any make of separator. It Is pressed from a single sheet of 

 steel, tinned to prevent rusting and so low that a 40-quart can can readily be emptied into it without lifting. In the hand 

 separators the Tubular bowl makes 16,000 revolutions per minute. The best of the disc machines make as high as 8,000; none 

 makes more. The reduced diameter of the Tubular makes possible a higher speed bowl, which in turn increases the centri- 

 fugal or skimming force. In the Tubular bowl the skimming is done by centrifugal force alone. There are no discs inside it. 

 Where the skimming is done with the assistance of discs, the wear and tear from constant daily use reduce the skimming 

 efficiency of the machine. Whereas the bearings of the Tubular bowl polish from use and run more freely. The double cen- 

 trifugal force generated in the Tubular bowl skims out the last trace of butter fat. When cows have been long in lactation 

 the globules of fat are smaller and consequently much greater force is necessary to bring about complete separation.

SHARPLES SPEED GOVERNOR PULLEY 



The Sharpies Gover- 

 nor Pulley can bo at- 

 tached to a Sharpies 

 Separator in an instant 

 — it clamps to the base 

 of the separator, one 

 screw is tightened and 

 no holes need to be 

 drilled. Prom this 

 Governor Pulley a 

 round belt runs to a 

 small grooved pulley on 

 the worm gear shaft. 



You can belt direct 

 from a gas engine, an 

 electric motor, or a line 

 shaft to the Governor 

 Pulley. It prevents any 

 jerks from the gas en- 

 gine getting through to 

 the gearing of the 

 separator. Variations 

 in the speed of the 

 engine are taken care 

 of by the governor 

 weights and shoes in 

 the pulley, so that the 

 separator always runs 

 at an even and proper 

 speed. 



A starting and stop- 

 ping handle is provided 

 on the Sharpies Gov- 

 ernor Pulley, which is 

 pushed in or pulled out 

 to start and stop the 

 separator. The power can be instantly applied or shut off 

 the separator — the engine or line shaft can be running while 

 separator bowl is at a standstill. Price, $18.00> 



STEAM TURBINE TUBULAR 



DAIRY SEPARATORS 



Just a jet of steam, not much 

 larger than would go through a 

 straw, drives it to full speed. 



An armload of wood or a bucket 

 of coal will furnish the needed fuel 

 for the smaller machines for an 

 hour's run.
