1 Claim.

This-invention relates to an improved means for dispensing grease or the like from the drums or barrels in which it is shipped.

An object of the invention is to provide a cabinet, Within which the unsightly drum or barrel may be placed and entirely concealed, and a pumping apparatus connected with the cabinet and having means enabling it to be quickly and easily attached to or detached from pumping relation with the drum or barrel.

Another object of the invention is to provide in an apparatus of the type described a suction pipe for the pump, which pipe is vertically slidable into and out of the grease drum within the cabinet and may be held in various vertical positions by a quick-acting clamp.

Another object of the invention is to arrange a clamping means for the suction pipe of the pump that will also act as a scraper, removing grease from the suction pipe as it is elevated preparatory to removal of a grease drum from the cabinet, the grease thus scraped off falling back into the drum within the cabinet.

These and other objects will best be understood as the detailed description proceeds and will be pointed out in the appended claim.

The invention will be disclosed with reference to the accompanying drawings, in which:

Fig. l is a small-scale, exterior elevational view of a grease dispenser embodying the invention, the parts being shown positioned for dispensing;

Fig. 2 is a small-scale elevational view,-taken reversely from Fig. 1 and showing the dispensing casing opened and the pump unit elevated to enable the removal of an empty grease drum and replacement of it with a filled drum;

Fig. 3 is a small-scale end elevational view of the apparatus;

Fig. 4 is a sectional plan View, taken on the line i4 of Fig. 2 and drawn to an enlarged scale to show the means for holding the pump unit in the desired position of vertical adjustment; and

Fig. 5 is a sectional view taken on the line 55 of Fig. 4.

Referring to these drawings; the invention includes a housing or cabinet A, within which may be placed and concealed a grease drum B, and on which is mounted a suitable pump unit of any kindsuch as the hand-operated pump C together with means for quickly connecting the pump to and disconnecting it from the drum. Usually also, a meter is provided and, in this case, it is incorporated with the pump C in the same casting and drives a register D which shows the measure of the grease discharged. The use of a meter is not a necessary element of the present invention. The pump is provided with a suitable d isc'harge means, such for example as the hose E.

"The cabinet A may be of any kind suitable for the purpose and, as shown in Fig. 3, has a panel Ill which is easily removable. With this panel removed, as shown in Fig. 2-, a grease drum may easily be put inplace therein or removed therefrom. This panel Ill is held in place at its lower end by a member H which fits into a suitable opening in the floor 12 of the cabinet, as shown inFig. 3 At the upper end of the panel In is a spring I3, fixed thereto. This spring frictionally engages a projection l4 fixed to the cabinet and serves to releasably hold the panel ill in its closed position. Any other suitable means may be used for the purpose. A handle I5 is provided on panel l0 and, by a pull on this handle, the spring l3 will be disengaged from projection I4, after which the panel may be lifted vertically iarenough to remove member H from its slot and is then entirely removed. The cabinet usually is provided with suitable casters I6 and a handle I! by which the cabinet may be pulled around .fromplace to place.

The pump C has rigidly connected thereto a suction pipe l8 which extends downwardly through the top wall 19 of cabinet A and normally enters the grease drum B, extending downwardly nearly to the bottom thereof as shown in Fig. 1. The top of the grease drum is usually removed in order to allow entry of the suction pip-e I8. Pipe I8 is free to slide vertically through an opening in the top wall [9, as will be clear from Fig. 5. When necessary to remove the drum B from cabinet A, one pulls upwardly on a bail handle 20 pivoted to the shell of register D, thereby lifting the interconnected pump and meter C together with the attached suction pipe [8 from the position shown in Fig. 1 to that shown in Fig. 2.

The suction pipe l8 may be held in place in either of the vertical positions described, or in any intermediate vertical position, by the means best shown in Fig. 4. As there shown, a wide strap 2| encompasses the greater part of the periphery of pipe [8 at a location near the top wall l9. This strap has two outstanding paralle1 ears 22, each provided with upper and lower strengthening webs 23. The strap is fixed in any suitable way, as by spot welding, to a bracket 24 (Figs. 4 and 5) which in turn is similarly fixed to a bracket 25, secured by spot welding or any other suitable way to top wall l9. The shank of an eye bolt 26 passes through both ears 22 and on its threaded outer end bears a knurled nut 21'. The inner face of nut 21 is intended to bear on one of the cars 22' and it has a pin 28 (Fig. 5) adapted to fit into any one of a series of depressions 29 in the ear which it engages, in order to hold the nut against rotation. The other ear is engaged by cams 38 (Fig. 4) on the webs 3| of a handle 32. A pin 33, extending through and riveted at its ends to the webs 3|, passes through the eye of bolt 26. The nut 21 is adjusted until the strap 2| grips pipe |8 with suflicient force when the handle 32 is in the position illustrated in Fig. 4. The handle is then pulled forwardly (toward the opening created by the removal of panel It). Then when handle 32 is pushed rearwardly (downwardly as viewed in Fig. 4) the grip of the strap on pipe I8 is relaxed so that the pipe may he slid up or down as required. Thus, a conveniently and quickly operable means is provided for holding pipe IS in its various positions of vertical adjustment.

The suction pipe is provided with the usual foot valve 35 (Fig. 1) and on its lower end has two lugs 36 which engage the bottom of drum B and space the inlet end of pipe I8 above such bottom of the drum.

The normal condition of parts is as shown in Fig. 1. The grease drum B with its cover removed or otherwise arranged so that the suction pipe l8 can pass therethrough, is entirely concealed with the cabinet, which may be given pleasing and attractive lines as shown. The pump is operated in the usual or any suitable way and grease is lifted up through pipe [8 and forced out through the dispensing hose E, being measured, if desired, as above described, and the measured quantities shown on the register D.

The invention provides the means for concealing the unsightly grease drum and also provides an arrangement whereby an empty drum B may be replaced with a filled drum with convenience and dispatch. One simply removes the panel l0,

as described, and pushes back on handle 32.

This loosens the grip of the clamping strap 2| on suction pipe l8 and enables the operator to lift the same out of drum Busing the bail handie 20 for the purpose if desired and raising the combined pump and meter C and the register D at the same time. The clamping strap 2| has also the function of a scraper for pipe |8removing most of the grease therefrom as the pipe is elevated. The grease, thus scraped oiT, falls back into the drum B. The handle 32 is then pulled forwardly, thus causing the strap 2| to grip pipe l8 and thereby holding the same with the pump in the elevated position shown in Fig. 2. Then the empty drum B is lifted out and a new drum put in place in the cabinet, the cover of the drum having previously been removed. The handle 32 is then pushed back to loosen strap 2| and release pipe l3. Then the pump is pushed downwardly, plunging the suction pipe 8 into the new drum B. When the pipe I8 is pushed downwardly as far as possible, the handle 32 is pulled forwardly, thereby again clamping the pipe I8 to the casing of the cabinet. The panel lil is then replaced and the apparatus is in readiness for subsequent dispensing operations.

The invention enables the change of drums to be eifected easily and quickly and also neatly, there being no occasion for drippings of grease to lodge on the floor or elsewhere.

What I claim is:

In combination, a cabinet having a fioor on which a grease drum is adapted to be supported and an overlying top wall together with side walls which form with said floor and top wall an enclosure complete except for an opening in the side walls through which opening a grease drum may be inserted or removed, a closure for such opening, pumping means, a suction pipe therefor mounted to slide vertically through said top wall and into and out of said drum, and a split-cylindrical strap fixed at a point between its ends to said top wall and substantially encompassing and closely fitting said pipe, whereby to scrape grease from the pipe while the pipe is moved upwardly and allow the scraped-off grease to fall back into the underlying drum, and means for drawing the ends of said strap together to contract the strap about said pipe whereby to clamp the pipe in any of the various positions of vertical adjustment to which it may be moved.
