GREASE-CUP.

Application filed March 26,1913.

To all whom it may concern:

Be it known that I, NORMAN WV. CUM- MINS, a citizen of the United States, residing in the city of Bridgeport, county of F airfield, State of Connecticut, have invented certain new and useful Improvements in Grease-Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in grease cups and pertains more particularly to the means for forcing the grease through the feed opening.

The primary object of the invention is to provide novel and improved means for feed ing the lubricant, and to further provide novel means for preventing retrograde rotation of the feeding element.

In the drawings: Figure 1 is a vertical sectional view of the invention; Fig. 2 is a side elevation; Fig. 3 is a section on the line 33 of Fig. 2; Fig. 4L is a section on the line of Fig. 2; Fig. 5 is a section on the line 5-5 of Fig. 2; and Fig. 6 is a fragmentary perspective view showing one of the ratchet teeth of the spring-held sliding collar.

The body 1 is formed with a reduced exteriorly threaded lower end 2 that is pro-' vided with an outlet opening 3, a collar or abutment i being suitably secured at the upper portion of the reduced end 2. The upper end of the body is formed with an outwardly extending flange 4 that engages with a flange 5 which extends inwardly from a reinforcing member 6, the free upper end portion of the member being forced inwardly to engage on top of the flange 4 whereby the latter is clamped between the flange 5 and the flange 7 that is formed by forcing said upper end portion of the member 6 inwardly. The periphery of the reinforcing member 6 is exteriorly threaded and is engaged with a cap 8 that has a hexagonal head 9 to allow same to be manually rotated. The lower end of the cap 8 is offset or expanded at 10 so as to extend outwardly from the major portion of the cap, and the lower edge of said offset portion 10 is formed with cut-out portions 11 to provide ratchet teeth, which are preferably two in number. A knurled collar 12 is formed with a hexagonal opening 13 at its center in Specification of Letters Patent.

Patented July 27, 1915. Serial No. 756,988.

order to allow the collar to have sliding movements lengthwise of the body 1, but to prevent rotary movement thereof relative to the body.

A. feature of the present invention consists in striking or pressing out ratchet teeth 14: from the body portion of the collar, which teeth are inclined with respect to the plane of the body of the collar in order to allow the ratchet teeth of the cap 8 to ride easily thereover. The ratchet teeth 1-1 which are struck out from the body of the collar 12 are closed on both sides, their front ends and the tops thereof, which results in maxi mum strength being imparted to the teeth, and increased wearing ability. A somewhat conical spring 15 has its lower end seating on the flange i and its upper end bearing against the body of collar 12, and being also engaged by the inner face of the knurled portion of said collar.

By expanding or offsetting the lower end or the bottom portion of the cap, as above described, the cap is materially strengthened, and by forming the ratchet teeth on this expanded portion, the threads on the interior of the cap, are not interfered with or mutilated, in movement of the collar to the position where it abuts flange 5, or in movement of the cap to disengage same from the body, due to the fact that the ratchet teeth are located in a plane outside of or spaced from the plane in which the threads of the cap are located.

The body 1 is reduced above the abutment 4 at a to form a shoulder 6, whereby, when it is desired to refill the body 1 with grease, collar 12 is forced downwardly against the action of the spring 15, to bring the opening of the collar 12 opposite to the reduced part a of the body 1, whereupon the collar is slightly turned to engage beneath the shoulder 6 to thus lock the collar against the action of the spring. The collar may be then rotated backwardly and removed. It will be apparent that the formation of the ratchet teeth is such that clockwise move ment only of the cup 8 is permitted.

What is claimed is:

In a grease cup, a body of angular crosssection having a threaded upper end, and an abutment adjacent its lower end, a shoulder on the body and spaced above the abutment, a collar extending in a plane at right angles to the longitudinal axis of the body offset end of the cap to provide an exposed Copies of this patent may be obtained for hand gripping part which enables the collar to be depressed and partially rotated to engage under the shoulder whereby to hold the collar inoperative during removal of the Cap and filling of the cup.

In testimony whereof I aflix my signature in presence of two witnesses.
