l Application led Aug'ust 16, 1911. Serial No.'644,422.

l,one of which screws onto the other and a spring detent is provided preventing acci-A dental displacement of the movable member with reference to the other.

The primary object of the invention isto,

provide such a cup in a form which shall be very simple and cheg'p at the Sametime' sha and durable. i

Another object is to provide a very neat.. and eflicient knurling for the cap of the cup.v To the above ends, the invention consists 'of the combinations of arts hereinafter described and summarize in the claims.

' In the drawings, Figures 1 and 2 are vertical diametric sections through the grease .cup in planes at right angles to each other; Fig. 3 is a horizontal section through the cup; Fig. 4 is a vertical section through a cap having a somewhat modified means for holding the detent spring; Fig. 5 is an elevation of such modified holder in a plane at y right angles to Fig. -4.

Briefly stated, 10 in the drawings repre'- lsents the stationary body or cup proper; 2O

` the movable cap screwing onto the cup' or body, 30 a spring holder carried by the cap, and 40a spring in such holder periodically engaging notches in the cup whereby the cap is prevented from accidental displace. ment.

Referring more specically to the parts shown, the cup 10 has an internal bore 11 below which is a reduced bore 12. Outside of this reduced bore are external threads 13 by which the cup may be secured into -a` suitable receiving thread. Near its upper end the outer wall of the cup has an enlargement 14 on which are external threads. The

bore 11. has preferably a cylindrical wall, 'and in this wall, parallel with the axis, are

formed rooves 15, such grooves being' arranged iametrically in one or more' pairs.

in construction, andbe eiiicient in service' mg.- The cap 20 is preferably a stamped sheet Vmetal member. It has a top portion 21 and a .wall 22' bounded by a cylin er but preferably having located about its surface, near 'One pair of grooves is'shown in the draw-- the top', ribs .23 parallel'with-its 4axis and f extending ajsufiicient distance from top to provide an eiicient finger hold for turning the cap. The outer surfaces of the ribs are vflush with the cylindrical wall. On the in ner face of the caps are threads 24 adapted tovscrew onto the external, threads onthe portion 14 of the cup...

Secured to the head 21 'of the cap vand de` pending the-feinte is a` flattened tubular holder 30 which carries the spring' 40. This holder is preferabl made of sheet metal plateben't on-itself m11) the form illustrated 1n Fig. 2, or in Figs. 4 and 5. Near its -upper end, portions of this holder pass throughoneor more openings inthe head of the cap and the upper 1end of the holder is f up-set or peenedeover, as shown at 32. In the form shown in Figs. '1 and 2, adjacent to the under face of the head of the -oa the holder `is provided with an outward ulge or bead B3. This head, together with the AHaring upward end of the holder cause it to be secured very rigidly to the cap. In the construction of Figs-4 and v5, the' holder 30 is cut'and bent at its upper end to produce a pair of separated tonguesV 34 which pass through two openings in the cap and are lthen upset.

The spring 40 is preferably of the U-shape shown, having a parallel-sided portion occupying the tubular space 30 andk two flaring end portions 41 with returning ends 42, thereby providing spring shoulders, which may occupy the grooves 15 or slide around the smooth wall of the bore 11 in passin one groove to the other. The spring is e fectively held in place by copeiating in ward ,projections or dents 34 formed by pressing inwardly the two flattened sides of thetubular member 30.l y

' My grease 'cup may be very cheaply made. As shown, it consists of but four pieces.

, The body may be conveniently cast or made otherwise, as desired, with the threads turned thereon; the cap may be stamped.
