which is extremely simple and durable in constructionas well as" eflicient in operation,

and which is so constructed and designedas 1b to reduce the liability of water leakage to a minimum;

A further object is to provide a pumping device of the above kind' which may be readily applied to various types of engines such as are now employed upon various makes of motor vehicles,'ancl wherein simple and practical provision is made'for operatively connecting the pump shaft to a driven part of the engine.

[Still another object is to provide a pumping device of the above kind which may be cheaply and easily manufactured "as well as readily placed into practical use.

f Other objects will become'apparent as the nature of the invention is better understood, and the same consists in the novel form,

combination and arrangement of parts herei'naitenmore fully described,shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views, v

Figure l is a top plan View of a pumping device constructed in accordance with the present invention; I

Figure 2 is a side elevationalview therev I Figure 3 is a horizontal section taken substantially upon line 3-3 of Figure 2;

Figure 4 is a vertical section taken substantially upon line 4- of Figure 1;

' Figure 5 is a side elevational view of the pumping device in operative relation to an internal combustion engine and the parts of its cooling system, said engine and cooling system parts being indicated by dotted lines; and V Figure 6 is a transverse vertical section taken substantially upon line 6-6 of Figure 5, showing the pumping device in front elevation. j Y Referring more in detail to the drawings, the present pumping device embodies a suitable supportingitrame or bracket 5, preferablyin the form or a vertical elongated late as shown suitabl re-inforced, and

adapted in any well known or preferred manner forrigid attachment to the engine with which the device'is to be used. As shown, the supporting plate 5 tapers'nan rower in a downward direction by having one edge thereof vertical and the other edge of the same inclined, and rigid with the vertical edge of this plate as well as extending substantially tromtop to bottom of the latter is a tubular shaft housing 6. Rigid with the upper'end of the plate. 5 and hous ing6 is a suitably shaped gear casing 7 having a water tight closure includingfa removable cover plate 8. Rigidwith the'low er end of the plate 5 and liousingtlis 'a'liorizontal pump casing 9 which may be formed in two parts or sections having a water tight joint and bolted together as shown" at 10. Thepump casing 9 isprovided .atjits top side with an axial inlet from which extends a lateral horizontal nipple 11 dis osed in a plane parallel with the plane 0 the plate 5 and adapted to facilitate connection of the bottom water outlet of a water cooling'radi; ator 12 with the pump through the use of a hose or the like as at 13, inthe usual gem eral manner. 1 1

" The pump further includes a rotatable impeller 1d disposed in the casing?) and fixed uponjthe adjacent lower end of a pump shaft 15 that is journaled in and extends through'tlie shaft housing 6 andprojccts upwardly into the gear casing 7 Suitable bearings 15 and 17 for the pump shaft l5 are provided respectively'at the lower end of the shaft housing 6 and the bottom of the pump casing 9, and meansis provided for facilitating lubrication of these bearings such as an oil or grease cup 18 carried by the housing 6 andassociatedwith bearings 16, and anoil supply pipe 19-communicating with the interior of bearing'l'i. As shown,- the lubricant is supplied to the bearing 17 through an opening 20 in the pump casing 9, the pipe 19 extending from the opening 20 upwardly beside the engine to a convenient point near the top of the latter as best illustrated in Figures 5 and 6. Thus, oil or other lubricant introduced into the upper end of the tube 9 will be conveyed by the latter to the bearing 17 in an obvious manner, The pump casing 9 is further provided with a peripheral or tangential outlet nipple 21 adaptedito be connected in the usualv manner as at 22with the inlet of the engine water jacket, the Outlet of which jacket is connected in the usual way as at 23 to the top inlet of the radiator '12 as illustrated in Figure 5. I

It will be understood that the manner of. attaching the plate 5 to the engine must necessarily vary in accordance with the various makes of engines encountered, so that no uniform example of attachment can be reliedupon. However, the selection of a suitable attaching means is well within the province of any skilled mechanic, and for this reason. no particular attaching means is disclosed. I

I Suitably secured upon the projecting upper end of the pump shaft 15 within the bottom of the gear casing 7 is a bevel gear 24 meshing with a similar bevel gear 25 secured upon the adjacentend of a horizontal shaft 26 extendingin a plane parallel with theplane of the supporting plate or bracket 5. The upper end of the plate or bracket 5 is formed with a pair of horizontally aligned bearings'27 and 28 in which the shaft26 is journaled, and these bearings are equipped with suitable oil or grease cups as at 29, While the bearing 28 is rigid with the adjacent side of the gear casing 7 and has the ad acent end portion of the shaft 26 extendlng therethrough and. projecting into the adjacent side of the gear casing.7 as shown clearly in Figuree. Suitable means isprovided upon the outer end of the shaft 26 for facilitating drivingfthereof from a suitable driven part of the engine. Obviously, this means will vary in accordance with different stages met with. In some instances, this means may necessitate the use of a sprocket wheel or spur gear fixed upon the end of the shaft 26, but as shown, it

may'embody a belt pulley 30 fixed upon said shaft'and adapted to be driven by a belt 31 passing about a pulley 32 fixed upon an adjacent driven shaft 33 of the engine, such as an extension of the pump or cam shaft of sald engine. In some instances, the belt Wlll also pass about a pulley 34 of. a shaft 35 carrying the usual air circulatingfan 36 by means of which air is drawn rearwardly through the radiator 12.

In most instances, it will be found most convenient to mount'the pumping device within the engine hood beside the forward side of the engine as illustrated in Figure 5 so that the nipple 11 projects forwardly and the nipple 21 projects rearwardly, while the shaft 26extends forwardly from the gear casing 7 so as to present the pulley 30 in the same transverse vertical plane as the pulleys 32 and 34. With this arrangement it will I of the device itwill also be found very convenient to bolt the-plate 5 to the engine. It is contemplated to pack the gear casing 7 with grease, and to replenish the supply of grease therein from time to time, the cover plate 8 may be formed witha filling opening closed by means of'a removable plug 37 An important feature of the present invention is illustrated clearly in Figure 5.

wherein it is shown that the pump casing 9 is positioned in a plane below the bottom connection of the radiator 12, while the gear casing 7 will be disposed in a plane above the top of the engine. Thus, with a packing gland "38 provided for the bearing 28 leakage of water will be rendered quite unlikely because any water finding its way upwardly through the housing '6 will be re sisted in outward passage to the bearing 28 by the grease or oil within the casing 7, and the packing gland 38 will not have to be able to resist a great pressure. because when From the above description it will be apparent that the present pumping device is of extremely simple and durable construction, comparatively leak proof, eflicient and durable. -It will also be appreciated that the device may be vended as an article of manufactureadapted for'attachment to engines already in use with very little change or modification'of the existing parts associated with the engine.

In operation, the driving of shaft 26 will be transmitted to the impeller 14, as stated, and the latter will cause the water to'be drawn into the pump casing 9 through connection 13 and nipple 11 from the bottom outlet of the radiator 12. The impeller will furtherv force this Water out of the casing 9 through connection 22 into the water j acket of the engine, from whence the water will the circle of circulation.

Minor changes may be made without departing from the spirit and scope of the invention as claimed.

What I claim as new is 2- A casing structure for water pumping de-' 7 vices consisting of a single piece casting comprising a vertical shaft housing, a gear casing at the upper end thereof, a chamber at the lower end for the reception of a fluid impeller, a horizontal shaft bearing formed on the side of said gear casing, a Web 10- cated in a vertical plane coincident With the axis of the vertical shaft housing and having at its upper end a shaft bearing,'
