GREASE-CUP.

Application filed May 23, 1916. Serial No. 99,402.

To all whom it may concern Be it known that I, Isaac H. ROHRER,

a citizen of the United States, residing at Los 'Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Grease-Cups, of which the followingis a specification.

My invention relatesto improvements in grease-cups in which a cap is screwed over a body-member for the reception of lubri cant, which may be squeezed or injected into a bearing by the movable interengaging of the cap andthe body; and the objects of my improvements are, to simplify the filling of grease-cups by eliminating the unscrewing and fitting together of the threaded interengaging of the cap and the body; to provide a cylindrical casing, screwed over the body of the device, with an open upper end to make the refilling possible from the upper end of the device; to provide the lower end of the casing with a shoulder preventing the casing from being unscrewed; to provide interlocking means near the upper edge of the casing; to provide a cap to close the upper open end of the casing having suitable cut-outs or recesses to engage with the interlocking means on the casing; the invention consisting in the construction, combination and arrangement of devices hereafter more .fully described and claimed, and illustrated in the accompanying drawing, in which Figure 1 is a vertical cross section through the device. Fig. 2' is a side view of the cap. Fig. 3 is a slightly modified construction of the cap in cross section. Fig. 4: is a section on line H of Fig. 3.

Similar numbers refer to similar parts throughout the papers.

The body 1 of the device is provided on the upper end with a short cylindrical part 2, threaded on the outside. A casing 3, threaded on the inside fits turnably on the threaded end of the body having a shoulder 4 on the lower end preventing the casing from being unscrewed in upward direction.

It will be understood that the device is placed on top of or near a bearing so that it may supply the latter with lubricant, and the casing 3 of my device cannot be unscrewed in downwardly direction as the device is normally too close to the bearing to allow a shifting to such an extent. The threads on a grease-cup are usually rather loosely fitting, and, after re-filling the cup, it very often happens that the threads do .not catch right and very soon are spoiled.

A main feature of my device is to eliminate this trouble of ruining the threads by constructing my device so that it can easily be re-filled without having to unscrew it.

Near the upper end of the casing 3 I provide projections or pins 5 as a locking means. The cap 6 fits over the casing 3 having cutouts 7 to engage with the locking means on the casing, see Fig. 2. In Figs. 3 and 4, a slightly modified construction of the cap is shown having suitably formed recesses 8 instead of the cut-outs 7 shown in Fig. 2.

Disengaging the cutouts or recesses of the cap 6 from the projections or pins 5 of the casing 3, the device can be re-filled from the top, and, after the re-filling the cap is engaged again as before, making cap 6 and casing 3 one member to be screwed in the same manner as other well-known greasecups. To make the upper end of the device tight, a gasket 9 is placed between the cap 6 and the casing 3.

Having thus described my invention, I claim 1. A grease-cup consisting of a bodymember, a casing movably engaging with the body member having locking means near the upper open end of the casing, and a cap fitting over the upper end of the easing engaging with the locking means.

2. A grease-cup consisting of a bodymember having a threaded cylindrical upper end, a casing turnably fitting with the lower end on the threaded upper end of the body-member having a projection near the upper end, and a cap fitting over the upper end of the casing engaging with the projection on the casing.

. 3. A grease-cup consisting of a bodymember having a cylindrical upper end threaded 0n the outside, a easing-turnably end of the casing engaging with the lockfitting with its lower end on the threaded ing means on the casing. 10 upper end of the body-member having a In testimony whereof I hereunto affix my locking means near the upper end of the cassignature in the presence of two witnesses.

ing, a shoulder formed on the lower end of ISAAC H. ROHRER.
