LUBBICANT-PUMPING MECHANISM.

, 1 Application tiled October 20, 1913. Serial No. 796,192.

Toall lwhom it mag/,concern n 1 `Be it known that I, WILLIAM E. TEKLEN- i' BURG, citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio,"have invented certain new and useful'lmprovements in Lubricanty Pumping Mechanism, `of which the followis a specification.

y invention relates to improvements in lubricant pumping mechanism.

kOne of its objects is to provide an 17mproved pump, 1n which the operative parts f y are all housed and (protected from injuryk f dirt whilethea j l5 ustments to operative parts and access to valves may be readily made and had from the exterior.` `Another object is `,to provide improved means, whereby the ypump may be selectively "Another object is to provide an improved ".fassembly of casing, operative parts and *y valves, whereby the machine work required reduced to `a in quantlty and singplicity in nature.k

y invention also comprises certain detals of form, combination, and arrangekk', improved mechanism on line a-a of Fig. 2.,

lment, all of which will be fully set forth in the description of the accompanying draw-` ings, in which: y n

Figure 1 is a vertical section through my Fig. 2 is a section through the same on line b-b of Fig. 6. Fig. 3 is an enlarged sectionaldetail of the pump cylinder, plunger,

andy adjusting .mechanism detached. Fig. 4

j iis a sectional detailH illustrating the ratchet driving mechanism,on line d-d of Fig. 1.

` Fig.-5 isa rear end yview partly in section on line 0 0 of Fig. 6. Fig. 6 is a frontend elevation. Fig. 7 is a perspective view of the strainer cap and latch detached.

The accompanying drawings representthe ji preferred embodiment of my invention, in

which A represents a rectangular metal casing, in which the operative parts are mounted and housed. The operative parts and valves are so arranged with reference to the casing, that throughholes may be bored in the casing and similarly tapped if required to provide the requisite ports and passages, thereby reducing the `work requisite on the `casing to a minimum.

B represents the main or operating shaft which is journaled at one end in a blind journal boX 2, tapped into the rear end of the casing. The opposite end of shaft B is journaled in a blind recess or bearing in the sleeve 3, which in turn is journaled in a sleeve bearing 4, tapped into the front end of the casing and provided with a packing gland 5. The sleeve 3 outside of the casing has a crank arm 6 keyed thereto and a crank arm 7 loosely journaled thereon. The crank arm 7 is attached by means of an extension rod 8 to some reciprocating part of the mechanism to be lubricated to cause the crank arm 7 to oscillate in unison with the movements of said mechanism. The crank arm 6 has a handle 9, by means of which it maybe turned by hand to give an initial charge of oil to the mechanism, or for other purpose, and is also provided with a spring actuated dog 9 or stud to engage a recess 10 in the crank arm 7 to lock said crank arms together and cause them to move in unison.`

`Said stud is disengaged from the crank arm 7 when it is desired to turn crank arm 6 by hand by pulling outwardly on the handle 9.

At the inner end of the sleeve 3, is a crank arm 11 armed with a pawl 12 which engages the teeth of a ratchet wheel 14C keyed upon the sha-ft B. A pawl 15 pivotally attached to a bracket 16 on the inside of the casing also engages the teeth of saidratchet wheel to prevent it being turned in a reverse direction. Rigidly mounted upon the shaft B is a cam 17, which engages a yoke or strap 18, carried by a rod 19, which is thereby reciprocated endwise. The rod 19 is supported at one end in a recess bored in a boss 20 carried by the casing and at the opposite end in a sleeve 21 threaded into a hole bored in the rear of the casing.

An arm 22 carried by the rod 19 is provided with a measuring pump plunger 24, which reciprocates in a casing or sleeve 25, one end of which is screwed from the 1nside of the casing into a threaded opening 26 in the lower portion of front of casing A. The cylinder 27 of the measuring pump is adjustably seated in the bore of the slee-ve 25, being adjustable endwise therein from the exterior of the casing to predetermine or vary the amount of lubricant forced through the cylinder 27 at each stroke of the plunger. The forward end of the cylinder 27 seats in a recess in a sleeve 28 threaded into the forward end of the Y threaded opening 26, said sleeve 28 being 2 Y Y v Lf... V.

provided with a threaded shaftm29 rotatably V held in place with reference to the sleeve 28 by a packing gland 30, and with its inner end threaded into the forward end of the. cylinder 427 to adjust said cylinder endwise'. A pin 3l sliding in a keyway in the sleeve 25 prevents the cylinder 27 from rotating.

'lhe lubricant is fed through a strainer into the interior of the casing' or reservoir A, from which it enters a port 33 in` Vthe sleeve 25 and thence through `a port 34 in the side of the cylinder 27,' when `said port 34 is uncovered by retraction of the plunger 24. The lubricant is expelled from the cylinder 27 b'y the forward movement of the plunger 24 'and escapes through a 1 port in the cylinder 27, and a slotin the inner end of the sleeve toa ballcheck 1falve 36 and thence through port 37 to another check kvalve 38, and thence'by tube'39 'to a transparent sight chamber 40. The'lcylinder 27 being normally submerged in oil avoids liability of air or gases enteringat the' ports 33 and 3i4'to thereby alter* the v'volume of lubricant pumped through thecylinder 27. The plunger 24 makes strokes vof uniform length, and when the 'plunger is :retracted the oil flows in'atport 34y as'soon' as said port is uncovered by the plunger,

fand A(':ontin'ues `to flow iny until ythe plunger is `fully retracted. On `the forward stroke the j oil'is y'free to flow in `the opposite direction from tliecylinder back 4to 'the casing A until the plunger again covers fthe 'port 34, after which the oil remaining in cylinder 27 is' forced'through the check valves-36 and 38,

y hence "when there is practically no vclearance between-the end of the `plunger'and inner end of the cylinder, the maximum volume of lubricant is being pumped, and correspondingly less volumes are pumped'as'the' v cylinder 4is adjusted endwise in its supports lto `increase the amount of clearance bet-Ween the cylinder head vandthe end ofthe plun- Lger, due to a portion of the oil in'the. cylinder not being expelledby the plunger.

-Froml'the chamber 40 the oil gravitates through a port 41 in thewallof the casing A to a curved recess 42, -open on the outer face ofvsaid casing at apoint 7 where the face of ysaid casing is dressed or faced. A pump cylinder 43 passes through openings 44fand 45 in opposite sides of thecasing A,

- one of which openings 44 is concentric with the bore of the cylinder 4 3, and a packing ugland 50 preventsleakage from said cylinclaim is der. A cross bar 51 connects the plunger 49 with the're'ciprocatin'g rod 19 outside of thek casing, thereby causing said plunger to reciprocate in unison with said rod 19.

Oil is passed from the curved Arecess 42 through ports 52 to two check valves 53k and .and thence into the cylinder 43 through a port 55 as the plunger 49 is retracted.

When the plunger 49 moves forward the oil in cylinder 43 is positively expelled through lthe port 55 and past they check valves 56 `and A57 and thence through'a pipe' linel i to a point where it is tobe used as a lubricant. `The valve chambers for

vthe valves

5,3, 54, 'and'56,-`57, are formedin the enlarged head of the cylinder 43 andare accessible from fthe'fexterior of the'casing. The valve 36'is also accessible 'from'theexterior of the casl ing, and also the means for adjusting the v "cylinder 27.

A detachable'sheet metal cap -58 closes an `opening-at the top of -the casing A and' permits access-'to theinterio'r of the casing ifrequired.- A stamped vsheet 4metal cap -59 closes `the 4opening to the `strainer -32 "a-'notch62 in the top rim of the strainer casing. `f

I -Inpracti'c'eone' ormore of the heretofore described measuring and pumping mechaynisiiis may be mounted side by sidein a single casing, or4 in afcasing subdivided by partitions toV independently lubricate different portions of a mechanism, measuring and feeding Vthe quantity of lubricantreand isv pivotal-ly'held in place by a'screw 60, and locked in closeddposition by an integrally` formed spring latch member 61 engaging f quired by each, of a single, or different y V`grades of lubricant.
