Application iiled May 20, 1902. Serial No, 108,154. (No model.)

To a/ZZ whom,` it may concern:v

Be it known that 1, GERHARD REIMERS, a citizen of the United States, and a residentof New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Grease-Cups, of which the following is a specification.

Myinvention relates to grease cups or boxes for lubricating the journals of machinery, and especially that class of such cups in which a pendulum is employed to eect an intermittent feeding of the grease to the desired journal.

The principal object of my invention is to so construct a cup ofv this character as to adapt it to be supplied with grease without its removal from the journal-bearing; and to this end it consists of the novel features hereinafter described, and illustrated in the accompanying drawings, in which- Figure I represents a vertical section of a grease-cup embodying the invention. Fig. II represents a top plan view thereof. Fig. III representsa side elevation thereof. Fig. IV represents an end elevation thereof. Fig.

V represents a horizontal section thereof in the plane of theline 55, Fig. I.

`Corresponding parts are marked with the same letters of reference in each of the figures. The letter Aindicates the body of the cup, which in end view is Vof approximately rectangular shape and which is open at both the top and bottom for the introduction and discharge of the grease. body is in form of a mouth A', flaring upwardly from four sides, while its bottom A" converges downwardly from two sides or ends and terminates in a nipple A", whereby the cup is in practice secured to the desired journal-bearing. Within the lower part of the cup-body are feed-rollers B B', which are mounted on parallel shafts and are fluted or corrugated in the line of their axes and which intermesh with each other, they being of equal diameters, so that if a rotary motion is imparted to either of said rollers such motion is transmitted to the other. The motion of the feed-rollers B B' is an intermittent one and is imparted to the roller B from a pendulum C, located eXteriorly of the cupbody (see Figs. III and IV) through gearing to be hereinafter described, and the throw of said pen- `F, while the stop D' is a set-screw which passes through a concentric slot F" in the disk into the cup-body, so that the last-named stop serves also to hold the disk in the position to which it may be adjusted. An auxiliary pin D on the disk serves to limit its adjustment in Lone direction by contacting with the set screw D', as shown in Fig. III.

Fitted on the cup-body is a lid or cover G, which is hinged to the part A', as at G', and acting on said lid is a spring H, having a tendency to close and retain it in a closed position, in which position the lid is fastened by means of a suitable catch t. In the example shown the spring H is of spiral form and is fitted on a slide-rod J, which is hinged at one end to a bracket J' on the cup-body and which works in an offset J" on the lid. The spring H is interposed between the offset J and alange 0 on the slide-rod, so that in opening the lid the spring is contracted. An advantage of said arrangement of the spring H is that it allows the lid G to be swung back beyond the perpendicular and remain open while the cup is being supplied with grease.

The gearing referred to includes a stud N, on which are mounted the pendulum C, a pinion N', and a ratchet-wheel N". Engaging the ratchet-wheel N" are spring-dogs P P', one on the pendulum forming a driver and the other on a fixed cup part forming a detent. The pinion N' meshes with a cog-wheel Q, (see Fig. IIL) mounted on a stud Q', on which is also mounted a pinion Q", (shown by dotted lines,) meshing with a cog-wheel R, which is mountedv on the shaft of the feed-roller to be actuated. The pendulum C may be provided with one or more adjustable weights, as C', for varying its load.

At a point below the feed-rollers B B' in the cup-body are two springs S S' (see Fig. I)

in the form of blades, which are of a suitable shape to impinge against the roller-teeth, thereby tending to retard the motion of the rollers. The spring-blades S S' project inward from opposite sides of the cup-body, and thus intersect the spaces between the rollers IOO and the body/,as shown, so that the blades also prevent backward flow of grease.

In some cases the part C, which I have termed a pendulum, may be connected with a moving part, such as the crank-rod of an engine, to receive a positive motion.

From this description it will be apparent that the cup may readily be supplied with grease through its open top and without its removal from the journal-bearings, While when the cup is in use the grease is properly fed to the journal by means of the corrugated rollers.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a grease-cup, a cup-body open at the top and bottom, corrugated intermeshing feed-rollers within said body, a pendulum exterior of the body and gearing adapted to transmit motion from said pendulum to one of the feed-rollers, substantially as herein described.

2. In a grease-cup, a cup-body having a flaring open mouth and a converging bottom,

the latter terminating in a nipple, corrugated feed-rollers within the lower part of said body, and a means for imparting an intermittent rotary motion to said feed-rollers, substantially as .herein described.

3. In a grease-cup, a cup-body open at the top and bottom, corrugated intermeshing feed-rollers within said body, a pendulum eX- terior of the body, gearing adapted to transmit motion from said pendulum to one of the feed-rollers, and a rotary adjustable disk having stops adapted to engage the pendulum, for regulating its motion, substantially as herein described.

4. In a grease-cup, a cup-body open at the top and bottom, a lid hinged to the upper part of said body, a spring adapted to act on said lid for retaining it in a closed position, corrugated feed-rollers within said body, and a means for imparting an intermittent rotary motion to said feed-rollers, substantially as herein described.

Signed at New York, in the county of New York and State of New York, this 7th day of May, A. D. 1902.

GERHARD REIMERS.
