H. GIBBS.
GREASE CUP.
APPLICATION mm mm 15. mm.-
TTE BBS HENRY GIBBS, OF CHICAGO, ILLINOIS, ASSIGNOR T0 W. D. ALLEN MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION.
GREASE-CUP.
Specification of Letters Patent.
Patented Dec. 4., TWL T.
To all whom it may concern.
Be it known that I, HENRY GIBBS, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grease-Cups, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specification.
My invention relates to that class of grease cups in which provision is made for preventing the accidental rotation or working loose of the cap or cover of the cup, and the invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claim at the end of this specification.
Figure l is a View in central vertical section through a grease cup embodying my invention. Fig. 2 is an inverted plan view of the cap or cover of the grease cup. Fig. 3 is a plan view of the body portion of the grease cup with the cap or cover removed. Fig. 4 is a perspective view upon an enlarged scale of the cap or cover of the grease cup. Fig. 5 is a detail perspective view of the pin that will depend centrally from the cap or cover. Fig. 6 is a fractional view in section of the cup showing the manner of connecting the pin thereto.
The body A of the grease cup may be formed from stamped metal or as a malleable casting. In the upper part of the body A is formed a shoulder a upon which rests an annular spring B that is opened to form the parallel arms Z) that project inwardly across the central portion of the body A. The upper part of the body A is eXteriorly screw-threaded, as shown, to receive the correspondingly internally threaded cap or cover C that may be made either as a casting or from stamped metal.
Centrally of the cap or cover C is formed a polygonal opening 0 adapted to receive the polygonal upper end (Z of the pin D. This pin D is formed by being stamped from sheet metal and is of rectangular shape, the width of the lower part of the pin D being greater than the distance between the parallel arms 6 of the spring B between which arms the pin D extends when the cap C is in position for use. Below the shank d at the upper end of the pin D is formed a shoulder 03 at each side of the pin D, the shoulder d being adapted to bear against the under side of the top of the cap C.
In assembling the parts, the shank cl of the pin D is inserted within the polygonal opening 0 of the cap C and the upper end of the shank (Z (which shank is longer than the thickness of the cap) is upset or headed over, as at 03 (see Fig. 1), so as to firmly and rigidly hold the pin in position. Inasmuch as the shank cl of the pin D is of polygonal shape corresponding to the opening 0 in the cap C, it is manifest that when the shank of the pin has been inserted within the cap, the pin is securely held against the possibility of rotation with respect to the cap and the shoulder d of the pin '11) and the upset or headed portion 613 of the shank serve to rigidly secure the pin to the cap. By forming the pin D of stamped metal and with a shank of polygonal shape to set within a polygonal opening in the cap C, an extremely simple and effective means is provided for guarding the pin against r0 tation, and by providing the pin with one or more shoulders d, the upper end of the pin can be effectively upset, as at d to rigidly unite the pin to the top of the cap.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is The combination with the body of a grease cup having a spring, of a cap provided with a polygonal opening therein and a stamped metal pin having a polygonal upper end of uniform thickness with the body of the pin and set within said opening and upset on the top of the cap, said pin having a shoulder below its polygonal end to engage the under side of the cap, said shoulder being of uniform thickness with the body of the pin, the lower portion of said pin engaging said spring.
HENRY GIBBS.
