GARAGE Application filed May 15,
This invention relates to apparatus for dispensing lubricant under pressure.
In places such as assembly plants and garages, where lubricant is injected under pressure to machinery bearings, it is desirable and common practice to provide an apparatus which includes a container of large capacity. Usually such apparatus is provided with a single conduit leading therefrom for forming a direct contact with the nipples through which lubricant is injected to the machinery bearings.
An object of my invention is to provide a structure of the above described type which is constructed to fill the barrel of hand operated lubricant injecting apparatus, such as are usually furnished with automobiles and similar machinery.
Another object of my invention is to provide the outlet of a container, from which lubricant is dispensed under pressure, withmechanism for selectively feeding lubricant to a nipple engaging conduit, or to an outlet adapted to fill the barrel of another lubricant dispensing apparatus.
Another object of my invention resides in providing a rigid holder to which the outlet conduit and the nipple contact dispensing nozzle are attached.
These and other objects and the invention itself will be more clearly understood from the following detailed specification.-
In the accompanying drawings Fig. 1 is a side elevation of a dispensing apparatus, partially in section, embodying my invention;
Fig. 2 is a top plan view of the same;

of the axle. A metal supporting member 14 is secured to and depends from the opposite side of the frame and medially of the wheels 13. The support Hand the wheels rest upon the ground, or floor, when the apparatus is stationary, and the apparatus is tilted so that the weight is supported onlyon the wheels when transportation is desired. A pair of handles 15 are secured to the underframe and project upwardly and outwardly. The operator can control the transportation of the apparatus by the handles.
The top 16 of the tank is provided with a central aperture 17 and mechanism for conveying lubricant under pressure from the tank into an outlethousing, extends into the tank through such aperture. A. pump casing and conduit consists of a housing 18 which is provided with a base flange 19 adapted to be secured to the top of the tank over the aperture 17, and a cylindrical shell 20 is screwed to the threaded end 21 of the housing extending into the aperture. An inlet member. 22 is screwed into the lower end of the pump shell and is provided with an aperture 23 extending therethrough. A valve 24 is mounted with the inlet member and is adapted to be moved vertically, the normal position of the valve closing the aperture 23. A piston 25 is reciprocablv mounted in the shell 20 and is secured to the endof the rod 26. A rack 27 extends through the housing 18 into the shell and is secured to the piston rod. The piston is provided with a vertical aperture 28 which is normally closed by a spring pressed valve 29.
A gear 30 is positioned within the housing 18 and mesheswith the teeth of the rack 27 to reciprocate the piston, when rotated in opposite directions by the operator. The gear is secured to the shaft 31 extending through a wall of the housing, and an operating lever 32 is secured to the shaft externally of the housing. The down movement of the piston raises the valve 29 and closes the valve 24, so that lubricant in the shell will be forced above the piston. Upward movement of the piston closes valve 29 and opens valve 24,
drawing a supply of lubricant into the shell from the tank through the inlet member, and compressing the lubricant above the piston.
An outlet pipe 33 is secured to the housing and the operation of the piston will force lubricant through such pipe under pressure.
The reservoir and pump mechanism described are of a conventional form and my invention has to do with the conveyance of the lubricant from a reservoir which I will now describe.
I provide a distributing casing 34 into which the outlet pipe 33 extends and is in open communication with. The outlet pipe 33 is screwed into an inlet opening 35 in the side wall of the casing and is in open communication with the interior thereof. An outlet port 36 is formed in the bottom wall of the casing and an outlet port 37 is formed in the cap 38 which is secured to the top of the casing and forms a part thereof. The ports are in axial alignment and a hollow sleeve 39 extends through the ports and is slidably mounted therein through the interior of the casing. An outlet passage 45 is formed in the lower portion of the chamber in communication with the port 36 and a connection 40 is screwed therein.
The sleeve 39 is provided with a plurality of apertures 41 through the wall adjacent the lower end, and a plurality of similar apertures 42 are provided in the wall of thesleeve adj accnt the other end thereof. A pair of pins 43 are secured to the wall of the sleeve within the casing and a coil spring 44 extends around the sleeve intermediate the bottom wall 45 of the casing and the pins, to normally maintain the sleeve in upward extended position.
A nozzle 46 is secured within the end of the sleeve extending through the port 37 in the casing and a passage 47 extends axially through the nozzle. The exterior end of the nozzle is circular and the circumferential edge 48 thereof provides the contact with the lubricating apparatus which is to be filled.
A flexible conduit 49 is secured at one end to the connection 40, and is fastened to a hollow handle 50 at the other end. The end of the conduit fits upon a reduced end 51 of the handle and is secured thereto by a hose clamp 52 of conventional design. The handle terminates at the other end in an end wall 53 having an aperture 54 therethrough. The threaded stem 55 of a hollow nozzle 56 is screwed into the aperture in the end wall of the handle. An annular shoulder 57 is provided within the passage 58 extending through the nozzle and a ball valve is positioned within the passage. The ball valve 59 is normally held against the inner side of the shoulder by a coil spring 60 which bears against an inwardly extending flange 61 at the end of the nozzle, being thereby retained within the passage in the nozzle; A contact,
member 62 extends through the outer end of the passage in the nozzle and is slidable lengthwise in the nozzle. A flange 63 is spun inwardly at the end of the nozzle to limit the reciprocation of the contact member. The end face of the contact member is formed with a semi-spherical recess 64 therein and a passage 65 extends axially through the contact member, being larger in diameter-at the rear of the end face. A gasket 66 having a central aperture therethrough bears against the inner end of the contact member, within the passage in the nozzle and prevents lubricant from escaping between the walls of the contact member and the nozzle. A washer 67 is positioncd against the gasket, and a coil spring 68 maintains the washer and gasket in position, the spring bearing against the washer and the shoulder 57 which projects into the nozzle passage. A stem 69 extends through the inner end of the passage in the contact member into the passage in the nozzle. The stem is seated within the contact memher and is arranged to unseat the ball valve 59 when the contact member moves inwardly of the nozzle.
When the sleeve 39 is in its uppermost position the apertures 42 therein will be closed from the interior of the casing, as they extend within the walls forming the port 37, and the apertures 41 will lie within the interior of the casing in communication with the pump casing. The sleeve is provided wlth a partition member 7 0 intermediate the apertures in the opposite ends thereof, and lubricant'will be free to be forced through the end of the sleeve, the conduit 49, the handle 50 and into the end of the nozzle passage. When the valve is opened by the stem 69, the lubricant will be ejected through the nozzle and the passage in the contactmember. It will thus be seen that it is necessary for the contact member to be moved inwardly to permit the valve 59 to open and allow lubricant to be ejected through the nozzle.
The recessed end face of the contact member is adapted to fit over and against a contact face of a bearing nipple similar to that of the nozzle 46 to provide a leakpr oof contact therewith, which is manually maintained in a plurality of angular relations thereto. A nipple and contact member of this nature are shown in Patent 1,475,980, issued December 4,1923. J
The reservoir can be wheeled about, and can be replenished with lubricant through an opening in the top of the tank, over which a cover plate is removably secured. I have described how the lubricant will be forced from the reservoir tank through the flexible conduit to inject lubricant into bearing nipples, and in Fig. 3, I illustrate the sleeve in position to conduct lubricant from the reser* voir tank into a lubricating apparatus which is of a size furnished as equipment with an automobile. When the sleeve is in its lowermost position the apertures 41 are covered by the wall forming the port 36 and the apertures 42 lie within the casing so that communi ation is established between the pump casing and the end of the nozzle 46, whereby lubricant can be forced therefrom.
In my co-pending application filed on an even date herewith, I have illustrated a lubricating apparatus, wherein the container can be filled without disassembling the parts thereof and in which a passage extends through the handle and the piston rod beneath the piston carried within the container. The inlet end of the handle of such an apparatus is shown herein and reference may be had to my other application, above referred to for further details of such an apparatus.
In Fig. 3, 77 illustrates the end of the handle ot' a lubricating apparatus having a passage 78 extending through the end thereof, and an inlet member 79 is screwed into the end of the passage. A passage 80 extends axially through the inlet member and is normally closed at its inner end by a spring pressed ball valve 81. The pressure of the lubricant will urseat the valve when being forced through the inlet member and when there is no pressure the valve will seat to'prevent lubricant from escaping from the handle. The end face of the inlet member is formed with a semi-spherical recess 82 which is of suflicient area to re eive the circular peripheral edge 48 of the nozzle therein. By placing the recessed face of the inlet member in the handle against the nozzle 46 and exerting pressure thereagainst, a leak-proof contact will be mat e and the sleeve. w ll be pressed inwardly establishing COIIIIDIUIICHtlLJI between the upper end of the sleeve and the reservoir. lVhen such contact is made the operator reciprocates the piston forcing lubricant through the handle of the lubricating apparatus to be filled. Thecontact of the faces of the nozzle and inlet member are such that a leak-proof connection can be formed when the handle is held at various angles relative to the nozzle, as long as the passages therein remain covered.
The casing and sleeve will thus provide two outlets, one for filling a lubricating apparatus and the other for directly connecting with bearing nipples, either one of which can be placed in operative relation by direct manually maintained contact.
A bracket 83 is secured to the top of the pump casing to receive and maintain the handle of the conduit when not in use. A metal band 84 is secured around the tank and spring clips 85 are secured thereto and serve as retainers for lubricating apparatus, of the type which are filled from the nozzle 46.
Various changes can be made in the construction described without departing from the spirit of my invention and the scope of the claims.

In 'an apparatus of the character described, a lubricant reservoir tank, a dispensing casing in communication with said tank, said casing having a pair of aligned outlet openings in the wall thereof, a sleeve extending through said casing and the aligned openings therein, openings in the wall of said sleeve adjacent the opposite ends thereof, a partition in said sleeve intermediate the openings adjacent each endfthercof, and means for conveying lubricant under pressure from said tank into said casing, said sleeve being slidably mounted to selectively direct lubricant from the casing through either one of the outlets in the casing.
