1 Be it known that we, DANIEL B. Diss andOrTo E. HAMTIL, both citizens of the United States, and residing, respectively, at

Newark, Essex county, New Jersey, and

Rahway, Union county, New Jersey, have invented certain new and useful Improvements in Grease-Cups; and we do declare l3l16 following tobe a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it a appertains to make and use the same.

This invention relates to certain new and on the cup 2. a body and the screw threaded cap to prevent.

useful improvements in a grease cup and themethod of maklng the same, and per- .tains more particularly to an improvement shown in Letters Patent No. 1,088,770, dated March 3, 1914.

In the patent above noted, it was an aim.

to provide a frictional contact between the accidental retrograde movement of the latter, that is, the cap could be turned manu- .1 ally in either direction but with difliculty 3 through the resistance afforded by 'a leather disk carried by the bodyin the path of the screw threads of the cap. i The present invention has for the primary I 1 object to simplify the cup construction and disk thereon. v i

improve the method of mounting the leather i Fig. 3 1s a fragmentary vertical section a of the cup body showing the leather disk p position ready to be clamped; and

3 Fig. 4 is aview similar to Fig. 2 in which the disk. securing lip or spur is corrugated or pressed into the leather disk.

The grease cup is of the force feed type and comprises a body 1 having its top flange externally screw threaded, as at 2 to receive the screw threads 3 of the cap 4 whereby on turning down the latter the lubricant will be expressed through the discharge end 5 i of the cup body inan obvious manner.

50. up from a single piece of sheet metal and t In the present instance, the body is drawn immediately below its top flange has a lip or spur 6 thrown up, as is clearly depi ed.

in 8. This spur is preferably thrown up in cylindrical form to facilitate the p0- sltioning of the leather disk 7 thereabout, after which said spur is spun or curled outwardly and backwardly upon the body to clamp or clench the disk in place (Fig. 1).

The fibrous disk washer is of a diameter to extend in the path of and engage the ca threads 3 to afford frictional resistance su cient to eliminate retrograde turning of the cap. The periphery of the disk is smooth and, of course, the cap threads will score therein when screwed down.

- In instances where the inner periphery of the disk is circular, the clamping spur may be corrugatedor otherwise pressed into the disk, as at 8, to retain the same from rotat1on.

It will thusbe noted that the body and disk securing means is a simple and integral structure which fact renders the cup of an exceedingly practical nature, since previous constructions embodied a plurality of parts which were diflicult to assemble and costly in production.

.The hereindescribed method and construction equips the grease cup body with a disk securing means without the addition of a single part, the whole being drawn from a single piece of sheet metal. It is therefore obvious that the present cup' may expeditiously be manufactured with no parts to wear loose or become dislodged.

The washer is thus applied by merely slipping same over the end 5 of the cup and since the external contour of the lip conforms to that of the internal circumference of the washer, the latter is slid over lip '6 without cutting the washer. In other words the washer is applied in its integral form and without splitting same.

What is claimed is:

1. The hereindescribed method of securing washers intact to grease cups and without cutting of the washers, which consists in providing a bendable lip on the cup of an external form substantially corresponding to the internal circumference of the washer, then in sliding the washer over the lip and finally in bending the lip to engage beneath the washer to hold the latter in place.

2. The hereindescribed method of securing washers intact to grease cups and with- 851R euttirig of the Mil 214511918,'Whihiltists in fercil lgthe fieeigehg; V
