LUBRICATING-PUMP.

SPECIFICATION forming part of Letters Patent No. 648,689, dated May 1, 1900. Application filed March 9,1899. Serial No. 708,366. No mnlcl.i

To n.1] nfl/0711I imuy ormcfrn.:

llc it known that l, .louN li. MCCANNA, a resident ol' Chicago, in the county of Cook and State ol` Illinois, have invented certain new and useful Improvements in Lubricatihg-Pumps,- of which the following isa specification. y

My invention relates to certain new and useful improvements in what are known as 1o lubricating-pumps, which are smallpumps ordinarily operated from some reciprocating part of asteam-engine and employed to pump oil to any parts that it is desired tc have constantly and uniformly lubricated.

My invention is primarily concerned with a structure in lubricating-pumps whereby a single reservoir for the lubricating material may be employed in connection with two or more pumps which draw the supply there- 2o from and which pumps may be operated from the same driving mechanism.

My invention is further concerned with a novel structure and relation of the parts whereby the pump is removably secured in the oil-reservoir and operated by a piston reciprocating through the side thereof, being a structure wherein the only parts that .ever become worn can readily be removed and replaced.

3o My invention further relates to new and improved actuating mechanism for use in such pumps,and includcs,amongother things, a novel clutch mechanism whereby the reciprocating rotary motion is applied to a shaft to give ,it an intermittent rotary motion.

Referring to -the sheets of drawings, in which the same letters of reference are used to designate identical parts in all the views, Figure 1 is a central section through va reser- 4o voir employing two pumps. Fig'. is a central sectional view of the indicating mechauism. Fig. 3 is a front elevation ol an indicating mechanism detached. Fig. 4 is`an elevation of the actuating mechanism with some of the parts broken away to more clearly illustrate the details of the construction. liig. 5 is a sectional View of the actuating mechanism on the line 5 5 of Fig. 4. Fig. 6 is a similar sectional view on the line 6 (3 of 5o Fi'g. -i. Fig. 7 is a detail view, on a smaller scale, of one of tho clutch members om played tion C.

dicating mechanism.

iu connection with the actuatingmechanism. Fig. S is a plan view with the cap, indicating mechanism, and strainer removed. Fig. il is an inverted plan view ofthe actuating-slide, and Fig. 10 is a plan view of the base portion with the reservoir proper and the actuatingslide removed and a portion of the casing broken away.

The reservoir A, which contains the oil or 6o other lubricating material, maybe of the c vlindrical shape shown, although any other shape might be employed. I have shown this reservoir A as secured by the screws B or otherwise'on the hollow cylindrical base por- 65 The top ofthe reservoir A has the rectangular aperture D therein, in which aperture fits thecap E, which supports the iu- 'lhe aperture D is formed with the flange F therein, and upon 7o this flange F rests the flange G of the strainer Il, which, as shown, is of a shape to correspond with the aperture D. The flange (l et the strainer H rests on the flange F formed in the aperture, and the cap E, resting upon the upper side of the flange G and in the aperture D, serves to close the aperture and secure the strainer in place. The cap E is l'ormed with the portion J, which serves as a 'bearing or casing for the indicating mechan- 8o ism proper. The lloatK is provided with the' stem L, which may be graduated, as shown in Fig. 3,'to indicate the amount of oil that has been pumped out since the reservoir .was last filled. The scale on the stem L is graduated to cooperate with the opening in the upper end of the portion Jef the cap through which l it projects. It will be readily seen that the position ofthe float J will be regulated by the amount of oil in the reservoir and that con- 9o sequently the position of the stem L will in; dicate the amount ol' oil remaining'. To indicate the rate at which the oil is being pumped out, Iemploy the following constructien:

One side of the stem L is formed with the teeth N, which form a rack-bar which meshes with the gear-pinion 0, which with the gearwheel P, to which it is rigidly secured, is rotatably mounted upon the pin or shaft (3, roo passing through the aperture or recess formed in the portion J of the cap. Journaled upon e esac-see the rate of which movement will indicate thel rate at which the oil is being pumped out of the reservoir. To protect the pointer U, I may place a glass plate X in front of it'and conveniently secure it in the cap W by means ot the spriugaing Y, fitting into a groove Z in the cap or cover W.

The pumping mechanism proper consists of the irregular-shapedportion or piece A',

which has interiorly-screw-threaded openings in its bottom and top, and the passage B', connecting them, which passage is enlarged at the bottom, as seen. The screw-threaded valve-seat C' is screwed into the bottom of the piece A', and the ball-valve D cooperates therewith, -as will be readily apparent. The valve-seat formedby the upper end of the passage B" is closed by theball-valve E. The connecting-piece F' is screwed'into the 'upper end of the piece A' and has the aperture G' formed inv its lower side of a size to'accom` modate the movements of the valve E'. The

` pipe ll', which is screwed into its upper end,

serves to carry the oil to any desired place, and the holes J', bored through the central portion of this connecting-piece F', permit the passage of the oil upward to the tube Il'.

This pieceA' has the preferably cylindricall portion K' projecting out through a similarlyshaped aperture Iin the side of the reservoir A, and the nut L', coperating with the screwthreaded end of the cylindrical portion K', serves to hold this piece A' and its connected parts in'position. .Vhen itis desired to take the p'ump out for any purpose, it the cap E and strainer Il have been removed by lifting them out and the nut L' taken oit the pipe H can be moved. toward the center of the reservoir, the slots M", leading to the aperture D, permitting ,this movement. In the construction shown the cap E and the opening Dare elongated in the direction at right angies to the section in Fig. l, and by turning the pipe Il' so as to bring the longer portion of the part A' in line with the longer way of the opening it canv be withdrawn from the reservoir. Of course the reverse method is employed in assemblinhr the parts. The piston N' reciproeates in the bearing 0', formed in the piece A',and through the stuliing-box P', which is closed bythe nut Q', screwed into the cylindrical end l' of the piece A'.

-To reciprocate the pistou N', the shaft S' is slowly rotated by means to be subsequently described, and this'shaft S', which is mounted in bearings'forined in the base C of the ma passing through the shaft and into the lug. As the shaft S rotates, the lug T' cooperates with the interior bearing-surfaces of the downwardl y-proj ectin g lugs V', which are earr'ied by the reciprocating slide W", 4which moves back and forth in the openings (see Fig. 10) formed in the sides of the base C. A rectangular aperture X' is out in the slide W' to permit the necessary rotation of the camlug 'l". The ends of the slide `W' are turned upward, as shown in Fig. 1, and take into the apertures formed in the yokes Z', to be described. These pistons N' have the rectangular yokes Z' secured on their outer ends and into which the upturned'ends of the slide XV' project. In the outer ends of the yokes Z' are located the screws A2 and the jam-nuts B2 thereon, by which the length of stroke of the pistons N' is regulated to discharge any amount of oil that may be desired. readily be seen that if the screw A2 is in the position shown at the right handv of Figs. 1

and 8 the reciprocation of the slide YV' will not affect the pistou N', as the end of the slide W' will not contact with the yoke Z' to move it at all. If; however, the screw A2 is moved inward to a position corresponding to its position on the left-hand side of the malchine, after the slide l l' has moved to the thrown entirely out of operative connection with the slide \V', so that the operation of the pumps may be completely regulated in every detail.

To rotate the shaft S', l employ the .following mechanism: The vertieally-reciprocating rod C2 is supposed to be attached to any reciprocating part of the engine, and this is secured in any desired position to 'the member D2, which is pivotally mounted upon the adjustable bearing E2, secured in any desired position upon the swinging rod F2, the inner end ot' which is furnished with a clamping split ,ring G2, by which it is secured upon the collar lle, projecting outwardly from the circular plate J2. This collar ll`- may also extend inwardly, forming the collar K2, and the common aperture for these collars -forms a bearing by which the plate J2 is mounted upon the outer end of the shaft S', it being held in position by means ot the washer L2 and screw M2. Screwed upon or otherwise rigidly Secured to the shaft S' is the collar N2 which chine, has secured thereon the lug T', which is shown as fastened thereto by the screw U',

It will curved dog T2, pivoted thereto.

each composed of the body portion S2 andthe The outer clutch member is pivotally secured in the outer cavity by means of the screw U2, passing throughthe horizontal elongated slot. V2 in the face of the plate or disk .Pand taking into the bearing stud or piutle W2, upon which the clutch member is pivotaliy mounted by means of the circular aperture X2. The enlarged aperture Y2, which is conveniently square, permits the free passa-ge oi' the shaft and sleey@ K2. `Similarly it will be seen that the inner clutch member is secured in the innercavity by means of the screw-bolt Z", passing through the horizontal slot Asin th'e flattened face Q2 of the reservoir A and holding the bearing stud or pintle B3 in position. The operation of these parts will be readily apparent. As the part U2 reciprocat-es vertically, the arm F2 will he reci procated about the center of the shaft S' as api vot and in its moveo ment will reciprocate the disk J2, to which it is secured. As the parts stand in their normal position, as shown in Fig. 4C, the curved `flange T2 of the outer clutch member rests loosely against the inner side of the extended periphery P2 of the disk O2. As the arm F2 moves downward the tendency of the pivotal point of the c uter clutch member to approach the side of the extended periphery against which its flange T2 takes, owing to the swinging of the pivotal point in a circle, causes the flange T2 to bind against the widened periphery P2 and the disk O2 to advance with the outer clutch member during its forward movement. As the arm F2is raised the clamping eiect of the clutch is removed and the disk O2 remains still, and consequently the shaft S', to which it is attached, remains in its advanced position. The inner clutch member comes into play to-prevent an y possible friction between the disk J2 and the disk O2 from carrying the disk O2 backward. The action of the clutch member in this will be readily apparent, as if 'the widened periphery P2 of the disk O2 were moved backward it immediately tends to clamp the inner clutch member and its fixed pivotal point absolutely preventsany backward movement after it is once clamped.

As there is always a certain amount of gradual leakage out of the smiling-box, I provide the slide W with the grooves C3 directly beneath the ends of the stutlingbo \es,which carry this waste oil and discharge it through the apertures D3 into the chamber formed in the base U of the pump. This oil is discharged upon the cam bearing-surfaces, and even if it were not the oil which gradually accumulates in the chamber will eventually become deep enough so that the cud of the lug'l" lu its rotation will take into the oil and carry enough with it to` thoroughly lubricate the bearing-surfaces with which it contacts. To draw oil any surplus of oil that may accumulate in this chamber, I may provide the pipeES, opening into it, which is provided with the cock F8 for opening or closing it, as may be desired.

The complete operation ofthe pump will be readily apparent and no detailed description thereof is deemed necessary. It will be seen that the amount of the feed can be easily and readily regulated by the adjustment of the bolts and nuts A2 and B2 and that the indicator provided will always show the actual amount being pumped out. Of course it will be understood that vI might, if desired, employ only onel pump in the reservoir, or I may employ more than two, conveniently, arranging them in pairs and providing a` slide W' for each pair, or I might connect a plurality of slides or form them integral.

It will be understood that I do not desire to be limited to the exact form shown and dcscribed, but that my invention may be embodied in a variety of forms, and that I do not desire to be limited therein, except as necessitated by the state of the art.
