Patented Sept. 13, 1932 UNITED STATES PATENroFF'IcE JOHN LORNE BEATON, F PABKLAND, ALBERTA, CANADA, ASSIGNOR OF ONE-FOURTH TO GUSTAV ERNEST ANTON MALCHOW, OF STAVELY, CANADA GREASE GUN FILLER Application filed. November 5, 1930. Serial No. 493,539.

My invention relates to improvements in grease gun fillers, and the object of the invention is to devise a simple, clean and inexpensive means whereby grease guns may be filled with grease preventing any dirt getting into the grease either in the cans or with the grease as the gun is filled and alsopreventing the proper filling of the gun through quantities of air passing into the gun with the grease, and it consists essentially of the arrangement and construction of parts hereinafter more particularly explained.

Fig. 1 is a perspective view of my filler partially broken away. to exhibit the construction thereof.

Fig. 2 is a longitudinal section through the filler and gun (on a diminutive scale).

Fig. 3 is an elevation of the grease gun on the same scale as Fig. 2.

In the drawings like letters of reference indicate corresponding parts in each figure.

1 is a base provided with base standards 2 and 3 upon which is supported a cylinder 4 forming a grease chamber having a conical bottom 5. 6 is an opening in the apex of the conical bottom 5 from which extends a nipple 7 which is normally provided with a closing cap 8 which is screwed on to the end of the nipple. 9 is a circular cover for the open end of the grease chamber to which is secured a locking bar 10 having concentric slots 12 and 13. 14 and 15 are reinforcing bars secured to the cylinder 15 provided at one end with hooks 1O engaging the peripheral end of the cylinder 4 and provided attheir opposite end with threaded stems 16 extending through the slots 12 and 13 when the parts are in the looking position.

17 are nuts which are screwed on to the stems 16 and bear against the outer face of the bar 10. The bars 15 be secured to the walls of the cylinder 4 if desired. The cylindrical top 9 is provided with a central orifice 9 in which is secured afianged sleeve 18 by I means of a cotter pin 19 extending through the stem extension 20 of die sleeve U l 18. 21 is a threaded spindle formed integral with the sleeve 18 and extending axially of the cylinder 4:.

22 is a disc provided withpa nut 23 formed integral therewith which is screwed on to the spindle 21. 24'is a piston cup formed of leather or other suitable material secured to the disc 22. The stem extension 20 is pro-' vided with a diametric orifice 20 through which a handle 25 extends. 26 is a grease gun of common construction, the cylindrical body of which is provided with a filling ori fice 26 from which extends a nipple projection 27. The nippleprojection 27 is exteriorly threaded and normally provided with a covering cap 28.

When it is desired to fill the gun all it is necessary to do is to remove the caps 8 and 28 and insert the nipple projection 27 into the nipple tube 7 in the position shown in Fig. 2.

The handle 25 is inserted'through the orifice 20 and the spindle 21 rotated so as to .carry the piston cup 20 downward and force the grease into the interior of the gun through the filling orifice 26.

By this means it will be seen that the whole contents of a can may be inserted in my cylinder 4 and when the piston 24 is operated the grease is forced therefrominto the gun without any possibility of any dirt coming in contact therewith or any air entering the gun which will prevent the proper filling of the same, and also enable of the gun being filled of the piston for forcing the piston against the grease, a closure for the open end ofthe cylinder, a cross bar secured to the closure and projecting diametrically from each side thereof and having concentrically slotted end portions, and reinforcing bars having hooks at one end engaging one end of the cylindrical member, and threaded stems at the opposite end of such reinforcing bars extending through the aforesaid concentric slots, and nuts threaded upon the stems against the cross bar.

' JOHN, LORNE BEATON.
