OIL-PUMP :MEcHANIsM.

Application filed July 28,

The present invention relates to a means whereby the well known oil gear pump may be utilizedin conpinction with a Ford engine for circulating the oilto maintain the front sumps filled, soas t prevent the burnin'g out of bearings when the englne s mg clined upwardly and forwardly, such as when the automobile is climbing. a hill.

in the provision of a mechanism of this na- An important object of-the invention lies ture which may be incorporated with the standard parts of the engine without any extensive alterations.

A still furthervery important object of the invention'is to provide a mechanism of this nature which is exceedingly simple in its construction,strong and durable, inex pensive to manufacture, efficient and reliable in operation, easy to assemble and disassemble, and otherwise well adapted to the purpose for which'it is designed.

With the above and numerous other objects in view as will appear as the descrip tion proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of an engine of the well known Ford type, showing my im-'. proved mechanism associated therewith,

Fig. 2 is a rear elevation of the pump and supporting means,

Fig. 3 is a side elevation thereof, and Fig. 4 is a sectional elevation of the outlet attachment of the pump.

Referring to the drawing in detail, it will be seen that I have illustrated the well, known type of Ford engine 5 which is provided with the usual front plate 6 which is held in place by bolts one of which is shown at 7. A breather neck 8 extends from the plate in the usual well known manner. The fan shaft is indicated by the numeral 9 and is journaled in the bearing 10 on the arm 11 which is mounted on the bolt 7. A grease cup 12 is engaged in the bearing 10 in the usual manner.

The numeral 14 denotes a well known type of gear pump having the usual drive gear 15. The'numeral 16 denotes an L-shaped bracket having slot-ted ends. One slotted end of the bracket 16 is pierced by the bolt 7 and the 1926. Serial Nd, 125,561.

other slotted endithereof is pierced" a screw .17 or like fastening element which is V engaged with the gear pump 14. A plate 18 is provided with'right angularly extending end portions 19 and 20 extending in opposite directions, and slotted; A screw 21 pierces the slotted end 19 and engages the. gear pump. 14;. The grease cup 12 'pi'erces the other slotted end 20 and holds it in engagement with the bearing 10 of the arm 11'.

A gear 22 is fixed onthe fanv shaft 9 in any suitable manner and meshes with the gear 15. A pipe 24 leads from therear of the crank case of the engine forwardly and is bent as at 2 5 and rises upwardlyfor engagement with the intake 26 of the gear pump 14L An outlet attachment 27 is provided on the pump and includes a valve seat 28 intermediate itse'nds for receiving a ball valve 29 normally'jheld in place by a'ispring 30. The' spring 30 is tensioned and held inplaceby asuitable cap 21. I.

An outlet branch 32 is extended from the attachment 27 to one side of the valve seat 28 while a gauge extension 33 extends from the attachment to the other side of the valve.

seat; Thus the pressure is delivered to the gauge at all times. The valve 29 functions as a check valve. A pipe 34 leads from the outlet branch 32 to a cap 35 on the breather pipe 8. Itwill thus be seen that when the engine is in operation, the gear 22 will operate the gear pump, thereby pumping the oil from the rear of the crank case through the pump and into the breather and filling pipe 18, thereby maintaining the front sump filled, so

that the splash oil system will operate to lubricate the forward portion of the engine particularly when said engine is inclined upwardly and forwardly, such as when the automobile is climbing a hill.

7 It is thought that theoperation, advantages, and construction of this invention will now be clearly understood by those skilled in this art without a more detailed description. The present embodiment of the invention has been'disclosed in detail merely by way of example since in actual practice it attains the features ofv advantage enumerated as desirable in the statement of the invention and the above description. Numerous changes in the details of construction, and in the combination andarrangement'of parts may be resorted to without departing from the ing, and an oil cup associated with the bearspirit or scope of the invention as hereinafter claimed, or sacrificing any of its advantages.

Having thus described my invention, wha I claim as new is 1. Means for supporting an oil pump on an engine; wherein the engine includes a crank case, a timing gear cover plate, bolts holding the cover plate to the crank case,

an arm on one of said bolts terminating-in a bearing, a fan shaft journaled in the hearing; comprising an L-shaped bracket having its ends slotted, one slotted end being pierced by said bolt which mounts the arm, a screw piercing the other slotted end of the bracket for engaging the same with the oil pump, a plate having offset slotted ends, one of the slotted ends of the plates being pierced by the oil cup, a screw piercing the other slotted end of the plate and engaged with the gear pump.

2. Means for supporting an oil pump on an engine; wherein the engine includes a crank case, a timing gear cov vr plate, bolts holding the cover plate to the crank case, an arm on one of said bolts terminating in a bearing, a fan shaft journaled in the bearing, and an oil cup associated with the bearing; comprising an L-shaped bracket having its ends slotted, one slotted end being pierced by said bolt which mounts the arm, a screw piercing the other slotted end of the bracket for engaging the same with the oil pump, a plate having offset slotted ends, one of the slotted ends of the plates being pierced by the oil cup, a screw piercing the other slotted end of the plate and engaged with the pump, an outlet associated with the gear pump, a pipe connecting the outlet with the gear cover plate, and an inlet provided on the gear pump and a pipe connecting the inlet with the rear of the crank case of the engine.

3. Means for supporting an oil pump on an engine; wherein the engine includes a crank case, a timing gear cover plate, bolts holding the cover plate to the crank case, an arm on one of said bolts terminating in a bearing, a fan shaft 'journaled in the bearing, and an oil cup associated with the hearing; comprising an L-shaped bracket having its ends slotted, one slotted end being pierced by the bolt holding the arm on the cover plate, a screw'piercing the other slotted end of the bracket for engaging the same with the oil pump, and a plate having an opening pierced by the oil cup and another opening, a fastening element piercing the other opening for engaging the plate to the crank case.

In testimony whereof I affix my signature.
