GREASE-CUP.

Application filed .Tune21, 1913.

To all whom it may concern:

Be it known that I, GEORGE W. BOWEN, of r-iuburn, in the county of Cayuga and State of New York, have invented a certain new and useful Grease-Cup, of which the following is a specification.

This invention has for its object the production of a ratchet grease cup and particularly to constructions whereby the parts are compactly arranged and the spring concealed; and the invention consists in the novelcombinations and constructions hereinatter set forth and claimed.

in describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is an elevation, partly broken away, showing the position of the parts when the cap occupies a position at nearly the limit of its outward or upward move ment.

Fig. 2 is a longitudinal sectional View illustrating the position of the parts when the cap is screwed downwardly and occupies a position between its extreme positions.

Figs. 3 and l are detail views of the base and the holding member.

This grease cup comprises generally a base, a cap turning on the base, a non-rotatable holding member slidably mounted on the base and coacting with the cap to restrain turning thereof, and a spring located above the holding member and designed to pull upwardly thereon and hold the same engaged with the cap, the holding member and the spring being so relatively arranged that the spring is housed by the cap.

1 is the base which as here shown includes a head 2 and a stem 3 depending from the head and terminating in a threaded nipple d by means 01": which the base is attached in position in a hearing or other part to be lubricated. The stem 3 is also formed with an axial passage 5.

The head 2 is discoidal in general outline and is formed with a central opening for receiving the upper end portion of the stem 3, which upper end portion 6 is reduced thereby forming a shoulder against which the head 2 rests, and the projecting portion of the reduced portion 6 is riveted or spun on the upper face of the head 2, as indicated at 7.

8 is the cap threading on the head 2. The

Specification of Letters Patent.

cap may be of any suitable form, size and construction. 9 is the holding or ratcheting member non-rotatably mounted on the stem 3 and slidable lengthwise thereof, the member 9 being opposed to the head 2; and 10 is the spring interposed between the head and the holding or ratcheting member 9 and connected to pull upwardly on the member 9 and hold the same engaged with the cap 8 to hold the cap from turning.

The holding or ratcheting member 9 is discoidal in form and is formed with a central opening for fitting the angular wrench hold portion 11 of the stem 3. One of the opposing parts 2 and 9 is formed with an annular flange inclosing the spring 10 when collapsed. As here shown both the head 2 and member 9 are formed with annular flanges 12, 13 respectively, the flange 13 of the holding member being of sufficient diameter to inc-lose the head and its flange 12. The cap 8 and flange 13 are provided with intercugaging means on their edges as ratchet teeth let and 15, and the holding member is formed with diametrically opposite finger engaging lugs 16 by which said member can be pressed downwardly against the action of the spring 10' to disengage the ratchet teeth when it is desired to turn the cap 8 in a retrograde direction.

The spring 10 is of such form as to collapse into a plane and is here shown as conical and coiled about the stem 3 and interposed between the head 2 and holding mem ber 10, the larger end of the spring being preferably secured to the head 2 within the flange 12.

The opposite ends of the spring are connected respectively to the head 2 and the holding member 9 by means of eyes 17 in the form of loops passed through slots in the parts 2 and 9 and having their ends 18 clenched upon the outer faces of said parts 2 and 7. The eyes 17, associated with the head 2, are located near the flange 12 while the eye associated with the holding member 9 is located near the axial opening of said member.

In operation when the parts are in the position shown in Fig. 1, as when the cup is full of grease, the flanges 12 and 13 house the spring which, owing to the fact that it is conical, will collapse into a plane, and

when the parts are out of their position occupied in Fig. '1 and occupy a position .110

such as shownin F ig, 2, the barrel portion of the cap 8 and the holding member S) house the spring.

What I claim is:

A grease cup comprising a base including a head and a stem depending from the head, a cap threading on the head, a flat discoidal member having an opening slidably fitting the stem and held from rotation thereon, said discoidal member having an upturned annular marginal flange extending toward the head, and of suiiicient diameter and width to inclo'se thehead when the cap is removed, the flange being provided with means at its edge for coacting with the lower edge of the 15 cap to resist turning of the cap, and a conical coil spring around the stem and connected at one end to the head and at its other end to the discoidal member.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this lth day of June, 1913.

GEORGE XV. BOWVEN.
