LUBRICATOR.

SPECIFICATION :forming part of Letters Patent No. 681,848, dated September 3, 1901. Application filed June 4, 1900. Serial No. 19,050. (No model.)

To all whom z5 may concern.-

Be it known that I, GEORGE F. GODLEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Lubricators for Car-Axles, 85o., of which the following is a specication.

My invention relates to certain improvements in car-axle and other bearing lubricators in which there is a sufficient amount of vibration to cause the piston to pump the lubricant to the bearing.

The object of my invention is to so construct the lubricator that it will pump the lubricating liquid from the reservoir below the axle to the surface of the axle or other bearing to be lubricated.

In the accompanying drawings, Figure l is a longitudinal sectional View of a car axle box, illustrating my invention. Fig. 2 is a transverse sectional view of the axle and pumping device on the line 2 2, Fig. 1. Fig. 3 is a detached perspective view of the mechanism of my invention, and Figs. tand 5 are views of modifications of my invention. v

A is the car-axle box, which may be of the usual construction.

B is the axle in the present instance.

C is the bearing for the axle. This bearing can be made in any of the usual forms and is situated between the axle and the top of the box. Resting on the bottom of the box in the present instance is a frame D, having a tubular projection d. In the base of this frame D, within the tubular projection, is an opening d', covered by a valve t'. The Valve in the present instance is a ball which rests in a socket in the casing, although any other form of valve may be used without departing from my invention. The base of the frame is open, so that oil can gain access to the opening in the bottom of the casing and pass up into the chamber formed by the tubular projection.

E is a plate curved to fit the under side of the axle B. This plate has an opening e at the center, and surrounding the opening is a deep flange e', which extends a sufficient distance to overlap the ange CZ of the frame D. A spring F is mounted between the frame D and the plate E, so as to keep the plate always in contact with the lower portion of the axle. Thus there is a pump-chamber formed by the flange portion of the frameD and the flange of the plate E. Surrounding the upper edge of the plate is a bearing-rib e2, having openings e3, preferably at each corner, as shown in Fig. 3. The rib forms a pocket for the lubricant that is pumped up to the axle, thus insuring entire bearing of the axle. Snugly Iittin g the pump-chamber is a piston G. This piston is supported by a light spring f, resting on the base of the frame, the spring being proportioned to the amount of vibration or jar that is given to the car, so that the pistou will have a limited reciprocating motion Within the chamber formed by the two extensions d and e. In the piston is a passage g, and closing this passage is a valve c, preferably of the ball form shown. This ball-valve rests in a socket and is prevented from jumping out of the socket by a pin or other retainer. In a car-axle, forinstance, there is a considerable vibration not only due to the car passing over frogs and switches, but also due to the movement of the trucks, and by making the spring g just sufficient to support the piston, which I may term a floating piston, the piston will be given a limited vertical reciprocating motion. Therefore if a lubricant which will How is placed in the bottom of a car-axle box, as indicated in Fig. l, it will be drawn into the chamber of the frame D under the piston by the action of the piston. When the piston is elevated, it will cause the lubricant to ilow into the chamber, and when it is depressed the valve will check the flow; but the depression of the piston will cause the lubricant within the chamber to pass up through the opening g in the piston and enter the space above the piston. As soon as the piston is elevated again the valve c" closes the opening in the piston and the lubricant is forced up into the chamber of the plate E. As the jarring of the axle-box is constant, the movement of the piston is constant, so that there will be a steady flow of lubricant from the bottom of the box to the under side of the axle, the excess of lubricant flowing out through the channels at the four corners of the frame, .thereby lubricating the collars of the journal. The piston the lubrication of theA IOO and the openings are so proportioned that there will be a steady fiow of lubricant to the under side of the axle.

It will be understood that my invention can be applied to any bearing Where there is suficient movement to cause a reciprocation of the piston and where a continuous iiow of the lubricating material is desired and that the plate E can be modified without departing from my invention, which is essentially a cylinder communicating with the oil-reservoir at the base and with a portion of the axle or bearing at the upper end with a Iioating piston Within the cylinder actuated by the jar or movement of the box or the support therefor.

In Fig. 4 I have shown a modification of my invention in which a single cylinder E is used in place of the iianged frame D and the anged plate E. This cylinder extends from the under side of the axle to a point below the surface of the lubricant in the bottom of the box and is supported by a spring F. The cylinder has an opening in the bottom provided with a valve, and within the cylinder is a spring-supported piston having a valved opening therein. This construction may be used where the motion is limited; but I prefer to use the construction shown in Fig. l under ordinary circumstances.

In Fig. 5 I have shown a still further modification in which the cylinder is supported on a flaring spring and a flexible tube extending from the cylinder into the lubricant.

D and on the plate E at each side are lugs, and chains may be used to couple the lugs of the frame to those of the plate, as shown in Fig. 2, when it is desired to fasten the parts together.
