GBE CONTAINER AND GUN THEBEFOB.

Application led November 17,1921. Serial No. 515,99.

To all whom z't may concern.'

Be it known that l, WARREN B. HOPKINS, a citizen of the United States, residing at Brookline in the countl of Norfolk and State of Massachusetts, ve invented new and useful Improvements in Grease Containers and Guns Therefor, of which the following isa Specification.

lThis invention relates to an improved container for grease and to an improved gun in which said container may be positioned and whereby the grease in said container mayT be ejected from said gun.

'lhe object of the invention is to provide a container for grease which can be sold at which can be placed in a grease gun or grease cup, the same being particularl adapted for use in greasing the bearings o different parts of an automobile Without the user being. obliged to soil his yhands by inserting the grease in said gun or infsald grease cup. l

The invention consists 'in the improved container for grease hereinafter Jfully described and set forth in the claims, and the invention further consists in the combination of said container with a grease gun or grease cup capable of havin the container positioned therein, and a o capable of forcing the grease out of said container and out of said grease gun or grease cup.

The invention further consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Figure 1 is a side elevation of my4 improved grease gun with my improved ase container positioned therein.

Fig. 2 is a longitudinal vertical sectional elevation of the same, the plunger in Figs. 1 and 2 being broken away.

Fig. -3 is a detail longitudinal sectional elevation of the greaseJ container.

Fig. a is a sectional elevation illustrating my improved grease container itioned in a grease cog.

Like numeroJ s refer to like parts throughout the several views of the drawings.

ln the drawings, referring to Fi 1, 2 and 3, 5 is the grease container an o the grease gun. The grease container consists of a tube 7 preferably formed of paper, and

having its opposite ends turned inwardly to.-

form flanges 8 and 9. The tube 7 is provided with an endv closure 10, preferably formed of paper, and fast to one end of the y tube 7. with an orifice 11 in which is located a tapered eyelet 12 and the opposite faces of the eyelet 12 are covered with a frangible material 13 and 14, said frangible material being preferably thin paper.A rlhe end closure rests against the flange 8. The opposite end of the tube 7 is closed by an end closure 15 preferably composed of layers of cardboard. This end closure is slidable in the container 7 and when the container is hlled with grease, the slidable end closure 15 rests against the flange 9.

The grease gun 6' consists ofla tube 16` which is cut out at 17in order that the container i may be introduced into said tube. One end 18 of said grease gun i`s screwed onto the tube 6 and has an orilice 19 there.- in 'which aligns with the orifice in the eyelet l2. Said end 18 also has a conical projection 20 extending inwardly and forming a seat for the eyelet 12 of the end closure 10. A flexible tube 21 has screw-threaded engagement with the end 18. The tube 16 is also provided with another end 22 which' may be fastened to. said tube 0r it may be formed as a partthereof. The end 22 is screw-threaded to engage a screw-threaded actuating member 23 which is provided with Said end closure 10 is provided a. handle 2a at its outer end. The actuating I member' 23 also embodies therein a circular plate 25'which is rotatably mounted upon the inner end thereof. 'lhe plate 25 is depressed at 26 and mounted upon a reduced portion 27 of the member 23, the extremity of which is headedl at 28 'in a manner to allow the plate 25 to rotate upon the reduced ortion 27. The late 25 is slightly smaller in diameter than t e diameter of the slidable end closure 15'. The end 22 is also provided with a screw-threaded projection 29 to receive a cap 30.

The operation of the device is as follows s-Assuming the container to be filled with grease, the user inserts the end to which the end closure 10 is attached` through the orifice 17 and presses the same against the projection 20 whereupon the iran ible material 13 and 14 will be broken as i lustrated'in Fig. 2. He then moves the other end of the container into the grease gun and lll) actuating member 23 will cause the slidable end closure 15 to be pushed into the container and thus force the rease through the orifice in the end 18 anigl through and out of the tube 21. During theoperation of the actuating member 23 as soon as the plate 25 contacts with the surface of the end closure 15, vthe friction between the plate and the closure will prevent said plate from rotating with the actuating member and the latter is thereafter rotated without at the same time rotating the plate therewith, thereby also preventing any'tendency to rotate the end closure 15.

It will be seen that the plate 25 constitutes not only a means for advancing the lslidable end closure 15 in the container, but also performs the function of positioning'the tube at one end thereoin the grease gun, while the other end is positioned by the projection 2O of saidgrease gun. t

Referring now to Fig. 4, it will be seen that the general construction and operation of this device is the same as the device here-v inbefore described, except that the parts are smaller and are adapted to be detachably fastened toV different parts of an automobile in the usual manner. In this embodiment of m invention 5 is the grease con# rainer, 6 t e grease cup which is provided with a screw-threaded end 18 adapted to be screwed into a portion of an automobileor other machine. 10 is the stationary end closure an d is the slidable end closure. 23 is the screw-threaded actuating member, 25 the plate on the inner end thereof and v 24" 'the handle on said actuating member.

The grease cup 6 diers from the grease 1,@ aaai gun 6 in that it is open on opposite sides so that the container 5 can beinserted from either side thereof, thus rendering it possible to insertlthe container in the grease cup, in places Where one side of the greasecup may be rendered inaccessible by adjacent portions of the automobile or other ma chine to which the grease cup may be fastened.

It is evidentthat the screw threads may be omitted from the end 22 and from the actul frangible means sealing said c elet and another end closure slidable in sald tube.

2. A. grease container having, 1n combination, a paper tube, the opposite ends of said tube being turned inwardly and forming interior annular flanges, an end closure fast to one end of said tube and contacting with one of said flanges, an eyelet centrally located in said end closure and an interior end closure positioned to contact with the other of said ianges and slidable within said tube.

In testimony whereof I have\hereunto set my hand in presence of two subscribing witnesses.
