COOLING SYSTEM.
To all whom it may concern:
Be it known that I, EDGAR B. HOOVER, a citizen of the United States, residing at Spokane, in Spokane County, and State of lVashingto-n, have invented certain new and useful Improvements in Cooling Systems, of which the following is a specification.
My present invention relates to improvements in cooling systems for automobiles in which the internal combustion engine is cooled by the circulation of water in jackets around the cylinders of the engine for the purpose of extracting heat therefrom. Some well known types of circulation systems act on the principle that hot water seeks a higher level than cold water causing the water to flow from the lower radiator outlet pipe up through the water jackets, into the upper radiator water tank and down through the tubes of the radiator to the lower tank, to repeat the process. In many instances this system has been found inadequate for the purpose of cooling the engine, especially in warm weather. The primary object of my invention is the provision of means applicable for use in con-v nection with existing systems of the above named type, and operated fro-1n the fan shaft of the cooling system, for positively causing circulation of the water to insure the necessary working conditions of the engine with respect to heat.
With this object in view the invention consists in certain novel combinations and arrangements of parts forming a pumping system, as will be hereinafter more fully pointed out and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined andarranged in accordance with the best mode I have thus far devised for the practical application of the principles of my invention.
Figure 1 is a view in side elevation of so much of an internal combustion engine or motor as is necessary to illustrate the application thereto of my invention.
Figure 2 is an enlarged sectional view of the water pipe connection between theradr ator and cylinder head of the engine for conveying water to the former, and showing my screw pump therein with operative connections.
Figure 3 is a perspective view of a friction cone-wheel that is combined for use Application filed January 11, 1924. Serial No. 685,713.
with the fan-belt pulley for operating the For the purpose of identifying and dis closing the relationship of parts I have designated the engine cylinder head as 1 and the curved pipe connection between the cylinder head and radiator (not shown) as 2, and the water jacket for the cylinders as 3, through which the wateucirculates for cooling purposes. The fan 4, shaft 5, pulley 6 and driving belt 7 therefor are of well known or standard construction and the belt receives power from a suitable source as usual for transmission to the pulley 6. Power is supplied from this pulley for operating the pump of my invention through the use of a cone shaped friction wheel 8 which has spaced lugs 9 at its large edge that are capable of being bent over to engage the edge of the grooved pulley 6 to form a rigid structure to revolve therewith and drive the pump.
Within the connection pipe 2 and verticaly arranged therein I provide a screw impeller or spiral pump blade 10 integral with its hub-sleeve 11 and the latter is fixed to revolve with the vertically disposed pump shaft 12 which extends upwardly from below into the interior of the pipe connection 2 as shown in Figure 2. The pump shaft is provided with a long bearing sleeve 13 seated in the hollow interior boss 1 1 of the pipe 2, and at the top of the boss a fixed retaining collar 15 is provided for the shaft and screw impeller. The shaft projects upwardly within the pipe 2 at its longitudinal axis and is provided with a bearing in the cross bar 16 extending transversely of the' pipe 2 with its ends turned down as at 16 exterior of the pipe to form a close water tight joint in the pipe. A cone bearing or journal at the end of the shaft insures a stable rotation of. the screw impeller, in addition to the long bearing sleeve in the boss 14.
At the lower end of the boss 14; which projects beneath the lower end of the pipe 2 a hollow packing nut 18 is connected to form an oil or lubricating chamber and suitablepacking, together with a compressing washer 19, are located in the packing nut. l-Iard oil may be introduced into the packing nut and the shaft may be lubricated therefrom through the longitudinally extending groove 20 in the exterior surface of the sl lfi' Within its sleeve 13.
Atithe lower en'dof the shaft and exterior of the pipe 2 I a'flix a driven Wheel 21 of suitable type having a friction rim 22 of rubber or other siinilarmaterialfor contact with the cone shaped friction pulley 8 on the fan-belt pulley 6.
It Will be apparent that, asthe shaft is revolved through frictional contact of the .tWo Wheels Sand 21, the screw impeller or spiral'blade 10 is also revolved to lift or impel the Tl C61 through the pipe connectionfto 'the radiator tank for causing circu- .nections,now in use on automobiles.
latien of Water through the hereinbefore unen'tioned parts: for the purpose of extracting heat from the-engine cylinder. By the utilization of the cone shaped friction pulley wheelrattachment 8 the; pump device may lieadilybe adjusted for use \vith'the pulley (3 of the fan belt, and the pipe connection 2 may. be substituted for. existing pipeucon- For this purpose the original connectioirmay be -re1noved= andthe pipe connection 2 which is l lOlLOf Water is positively accomplished regardless of Weather conditions and the engines may becooled as required.
Having thus fully described my invention What I claim as new and desire to secure by Letters Patent is .The. combination with arooved nille f having flanges of a'friction cone, spaeed attaching lugs-on said cone'for engagement with one of said flanges to form a r gid structure, a shafthaving a suitable bearing,
a'friction wheel on said shaft and a friction rim on-said Wheelfor contact With the friction cone.
In't-esti'mony whereof I 'a'llixmy signa ture.
