My present inventionv relates to improvements in hydraulic pumpsy whichV while adapted for various uses, areespecially vdek signed for use in supplying motive; power for ,pushing industrial carriers or vehicles,

such as railway cars', through the tunnels lof kilns for ceramic ware. As thus used in the and therefore to secure niaXimum efficiency, the Vequipment must be rugged and durable, requiring a minimum amount of interrupservice.- v

So far as I am aware, n0 pumps or pushers, are nowv in use that can attain these desired results atan economicalV cost, and Iv have therefore devised the present pump for ac-V complishing these purposes.

tions and arrangementsV of parts involving `the motive fluidor hydraulic pump of the upright rectilinear type, and its automatic lubrieating system,wher eby vthe parts ofthe ma chine are compactly arranged and `readily accessible for packing,adjustments, repairs,

etc. l Y

In the accompaying drawings, I have illustrated one complete example of the physical' embodiment of my invention whereinvthe `parts are combined and arranged accordingr to the bestmode I havesovfar devised for.

Incariying outiny invention, Iihave pro- Ivioletta machine somewhat similar in design andappearance to the inotor Vfor an automobile, in which the lubrication is automatically provided for, and in which the operating parts are made accessible sothat re- 1--tion for repairs, oiling, etc.,vand indeiinite pairs i o'rfadjustnieiits Ymay readily beA made.

18,19, the latter gears on the eccentric-shaft `2O-whicli isjournaledin bearingsV 21 ofthe casing 11.' The eccentric shaft extends horioperated prefer- 'iii zontally above the pump base and as here shown is provided with three eccentrics 22 for operating a complementary number of pump units each including a connecting rod 23, slide head 24 with the wrist pin 25. These slide heads :are cylindricalland inthe formof pistons, and they reciprocate VKin Athe xupright cylindrical cross heads 26 which are cast .integtral with the .casing .or vhousing ll, and 0 these cross heads are provided withsuitab'le linings as 27.

To each slide head 23 a pump plunger 28 is secured with the lower threaded reduced end 29 of the plunger screwed 4'into fa comple- 5 mentargT socket 30 of the slide head.

Miovethe'top 13 ofthe/casing th-reelh'o'llow 'pump heads-3l are located, each having abottom boss 32 seated i-n an opening V33 and iselcuredas hy Lbolts to thetonl 13. The plungers reciprocate in these heads through packingjglands '34 and pack-ing nuts 35 4and 'each head has Ia chamber .'36 `communicating port 37 with the valve chamber '.33 -i-n which are located inlet ball valves 39 and outlet valves 40coacting withthei-r respective valve cessiue'l-.v force thesedharges Ioi" motive fluid lto ithe discharge manifold, and -pipe 6 in a substantially continuous and uniform stream to insure a regular Aand uniform pressure of motive fliuid for therpurpose `of propelling for pushing the kiln cars for'otlher vehicles. The motive fl-uid is continuously xcirculated and is of course replenished from time to time 'as required.

The suction and discharge manifolds cominunicate with all of the vpump heads fand eX- 'tend -tfransversely fof the heads with 4bosses 45 'seated insockets inthe sidesloi the heads and 'attachingbolts 46 are employed .to lcllamp 'the linanitolds Ito the heads. vrThe vertical chamihers138 fo-fth'e heads Aare lloore'd with fopen 'ends and these ends are closed 'by removable screw ,'pllugs 4^" to lprov-ide Yfacile means of Vgaining at) access 1to 1the pump heads whennecessary.

'The operating par-ts of the several pump units are lubricated automatically -byan oil 'pump wh-icl-roperaltes synchronously with the mechanism.

The oil is lifted past the outlet valve 53 into the pipe 58 and the iupiper'end otthisgpipe opens into a longitudinalgroove 58 from which extend a series `of lubricatingfgroovesi).

A pipe connection "63 Jis :made between the pipe 6l :and :the `casting 62, and ra sleeve '-64 is'cast integra-l with the Lbottom-'ot' the engine base.
