Application filed July 27, 1911. Serial No, 640,751.

To (ZZZ whom it may concern.

Be it known that I, Grouse W. BOWEN, of Auburn, in the county of Cayuga and State of New York, have invented a new and useful GreaseCup, of which the following is a specification.

This invention has forits object the pro duction of a grease cup which is particularly simple in construction. economical in manufacture and highly efficient and durable in use; and it consists in the combinations and constructions hereinafter set forth and claimed.

in describing this invention reference is had to the accompanying drawing in which like charaeters designate corresponding parts in all the r'iews.

Figure 1 is dVEilllCfll sectional view of one form my grease cup, and Fig. 2 is a View similar to Fig. 1 of another form thereof.

This grease cup comprises, generally, a base, a closure for the base, a follower movable toward and from the bottom of the base, and means carried by the closure for operating the follower,

1 is the base which is in the form of a receptacle, said base'being provided atitslower end with an axially extending nipple 2 by means of which the cup is connected to the part to be lubricated, the hi ple having a passage 3 therethrough whic communicates with the interior of the base 1.

4: is the head of the closure for the base, the closure being also in the form of a receptacle and having a barrel portion 5 projecting from the head 4 into the base 1 and normally terminating near the bottom 6 of the base. The closure is externally threaded and turns into internal threads of the base 1.

In order to prevent grease within the closure from following upwardly between the threads of the closure and the cap, the lower end of the closure engages, and em beds in a packing ring 7 of yielding material locate at the bottom 6 of the base 1, The head 4 overlaps the upper edge of the open end of the base 1, and opposing surfaces of the head and base are formed with recess and a socket designed to come into alinement when the closure approaches the limit of its movement into the base 1, and a spring-pressed locking partis located in the socket and projects therefrom in position to enter the recess. p

In the illustrated embodiment of my invention the base 1 is formed with a recess or notch 8 in its upper edge said notch decreasing in depth toward opposite sides of the notch extending through the periphery of said edge and the head is formed with a socket or perforation 9 extending through upper and lower surfaces thereof, in which socket the spring-pressed locking part as a ball 10 for entering the notch 8 is arranged, said locking parthaving a rounded lower portion projecting from the contiguous part of the head for entering the notch when the perforation 9 is alined therewith, and for coacting with opposite diverging sides of the notch during the turning movement of the closure and thus the locking part moves downwardly into operative position, or rises therefrom by the mere turning movement of the closure.

The spring means acting on the ball 10 preferably consists of a disk 11 of resilientmaterial mounted on the head and arranged coaxially therewith and with its margin extending across the upper end of the perforation 9, said disk being held at its center and having its margin free. The disk 11 is usually arranged in a recess 12 located in the upper side of the head l and formed by a marginal annular flange 13 extending upwardly from the head 4. Such recess 12 is closed by a disk 1% of sheet metal resting againsta seating surface 15 near the upper edge of the flange 13, the disk 14 being held in position by spinningthe upper edge of the fiange13 over on the upper face of the margin of the disk 14 into a pos1- tion opposed to the seating surface 15, as

clearly seen at 16, Fig. 1.

17isa follower movable between the head 4 and the bottom 6 of the base, said follower engaging the inner circumferential face of the barrel portion 5 of the closure. The means for operating the follower comprises a threaded stem 18 extending axially through a threaded central opening of the follower 17 and upwardly through the head .4 disks 11 and .14, the stem being held froni e'ndwise movement by an annular thrust bearing 19 engaging the bottom of a socket formed in the inner face of the head 4, and by a thrust bearingsurface 20 on the outer end of the stem 18, said surface 20 abutting against a washer 21 encircling the stem 18 and resting on the disk 14:. The disk 14 is held from yielding movement toward the disk 11 by a washer 22 similar to the washer 21, the washer 22 encircling the stem 18 I surfaces of the head and the fol.

' '1 l v: I ,1 6 mar a will 300,218 a spring against the can 10. he follower 17 is held. from turning movement with the stern 1 by suitable collapsible means interposed between onposin L A.

means being here shown as in the term 0. conical spiral spring fixed at one end 1 the head 4.-

at its other end to the follower 17. i

In order to preventcrushing of the 'spriu: 2 1- or other collapsible means, one of parts provided "with the opposing surfaces between which said spring 24: is interposed, is formed with an annular shoulder pro jecting toward the other of said opposing surfaces, the annular shoulder being concentrio with the spring and of greater diameter than the largest diameter thereof in order that when the follower l? is moved near: the head t, the spring 24 will be coiled wit-h in the annular shoulder. its shownin l the annular shoulder is provided on head t but as shown in Fig. .2 such shoulder is provided on the follower as indicated at 26. I

In operation, the closure is unscrewed from the base 1 and the handle operated to move the follower 17 upwardly to a position near the head 4 of the closure. lfhe closure is then filled with grease and screwed into the base 1 until'loclred from turning movement by, the ball 10. the lubricant is used the follower is forced toward the bottom of the base by turning the handle 23.
