Toall whom it may concern Be it known that I, GUY L. WILLITS, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Cooling Devices for Internal-Combustion Engines, of which the following is a specification.
My invention relates to cooling devices for internal combustion engines and the object gine to the radiator and back to the engine. A further object is to provide a gear pump for causing the circulation of water and to Operate a fan at a high rate of speed in connection with the pump. A further object is to provide a pivotally mounted pump casing which may be readily adjusted to take up slackin a flexible driving connection for operating the pump without at the same time removing the fan from its efi'ee tive sphere of action relatively to theengine.
The full objects and advantages of my invention will appear in connection with the detailed description and are particularly pointed out in the claims. Referring to the drawings Which show the application of my invention in one form,
Figure 1 is a view in side elevation of the device applied to an internal combustion engine. Fig. 2 is a view on line 22 of Fig. 1. Fig. 3 is a view in transverse section through the pump casing; Fig. 4 is a top plan view with the pump casing partly broken away.
In the drawings 10 designates the customary radiator and 12 the engine casing of an internal combustion engine, the two being connected at the top by pipe 1% in the usual way. The pipe 16 at the bottom of the radiator instead of leading directly to the engine, as usual, leads to the top of a pum casing 18, while from the bottom of this casing a pipe 20 leads to the engine. A bracket 22 is secured. to the engine by bolts 24 and the upper end of the bracket is turned forwardly and forked to provide the two branches 26. The pump casing is pivotally attached to the bracket by means 0 a laterally extending lug 28 thereon which fits hetween the branches 26 of the fork, while a bolt 30 passing through holes in the end of the lug and the two branches serves as a pivot. The pump casing is held in adjustable position by means of n lug 32 thereon Patented Apr. a, rare.
having an opening 33 through which passes a bolt 34 provided with lock nut36 on each side of the lug whereby the position of the pum casing may be adjusted. The pump casing is provided with the removable cover portion 38 held thereon by bolts to screw threaded into holes-42 in the adjacent edge of the casing". Within the pn p chamber 44 are two intermcshin 1 gears 46 and 48, the latter being considers 1y smaller than the .former. The geardti is secured to a shaft 50 mounted in hearings on the casing, the
shaft passing through a stulling box 52. The sh aft '50 may be driven in any suitable manher from the engine as by means of the customary fan belt either straight or crossed accordingto whether the fan is run clockwise or coiintercloclr-wisc. However, on accountof the .liahlhty of sl pping of a belt, I prefer to use the following driving means Secured on the outer end ofthe shaft 50 is a sprocket wheel over which passes a sprocket chain 56; which also puSSOS over a sprocket wheel 58 secured to the engine crank: shaft 60 which may he provided with. the customary crank handle Sprocket wheels 54. and 58 are preferably of the fsame'size. The
The operation and advantages of my in vention will be apparent from the foregoing description. The gears 46 and 48 serve asf a pump to take water from the bottom of the radiator through the pipe 16 and force it through the pipe 20 to the engine from which it returns to the radiator through the pipe i4. An efiicient circulation of water for cooling the engine is thus provided. On account of the gear 48 being smaller than the gear 46 the fan will be driven much faster than the engine crank shaft and the coolinn effect of the fan. is therefore much in creased. On account of the pivotal mounting of the pump casing the same may be readily adjusted by turning the lock nuts 36 for the purpose of tightening the sprocket chain or whatever driving means is employed. On account of the location of the fun shaft upon ice the'casing on the side of the sprocket 5;i toward the pivot, adjustment of the ca. 11 r daes not change thehpigsition of the fan biveiy tn the radiator iiiiicient1yto have zihy efiect on its eificient operation.
