VVENTOR UNITED STATES PATENT Erice..

GEORGE F. GODLEY, OF PHILADELPHIA, PENNSYLVANIA.

CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent o. 381,691, dated April 24, 18.88.

Application filed December 27, 18E?. Serial No. 959,138. (No model.)

To ali whom t rtczy concern:

Beit known that I, GEORGE F. GODLEY, a citizen of the United States, residing at Phila` delphia, in the county of Philadelphia and State of Pennsylvania, have invented certain neuv and useful Improvements in Lubricating Devices for Car-Axle Boxes, of which the fol lowing is a specification.

My invention has relation to pumping devices for raising oil from the well of car-axle boxes to the axlejournal and brass or bearing for lubricating the same; and it has for its ob ject the provision of a pump having pipeconnection with the bottom of the axle brass or bearing and with the axlebox oil-well, and operated by the endwise movement or thrust of the axle.

My invention accordingly consists of the combinations, eonstructions,and arrangements of parts, as hereinafter more fully set forth in the specification and claims, having reference particularly to a stop bar or key placed transversely in the axle-box in front of the end of the axle to limit its endthrust, which bar is removable from the box and preferably has upon it a pump, which is so mounted thereon that the outer end of its piston abuis against and is reeiprocated by the endwise movement or thrust of the axle to effect raising of oil from the axlebox Well to the journal-bearing for the axle.

Reference being had to the accompanying drawings, Figure 1 represents a longitudinal section, partly in elevation, of a car-axle box and part of the axle, showing my improvements; Fig. 2, a perspective of part of the same; Fig. 3, a detail section showing modified form of pump; Figs. 4 and 5, detail perspectives; and Figs. 6, 7, 8, and 9, detail sectional views.

Arepresents the car-axle box, which may be ofthe usual or other construction, as indicated; B, the axle-journal; C, the brass or bearing therefor, and D a form of stop bar or key in front of the end of the axle for limiting its end thrust or movement. This bar D is, as shown, preferably placed transversely in the axle-box, and one end, d, may fit into a socket, a, cast, formed, or secured to one side, a', of the axle-box, (see Fig. 2,) and the other end, d', of said bar may be provided with an elongated open-end slot, di, (see more plainly Fig.

5,) for engagement with a horizontal rib or projection, e?, on a vertical lug, a?, cast or secured tothe opposite side, c, of the box, said lug and rib being more plainly indicated in Fig. 4.

Parallel with lug e3 and at a suiicient distance from the outer surface of rib ai, corresponding to the width of bar D, another vertical lug, a5, having preferably an inclined side, a6, may be cast or secured to the side a* of the axle-box. The slotted end d of bar D, when used, is preferably formed or provided on its outer side with a lug or recess, da, so that when said end of the bar is slipped into engagement with the rib et (see Figs. 2 and 7) and a \vedge,f, is inserted or driven vbetween bar D and lug c5, for firmly holding the bar in position in front of the axle end b, the wedge fis also retained in position against sidewise movement by the axle box side a* and the lug on bar D.

By loosening or displacing Wedgef the bar D may be removed at any time through the axleboxlid opening A.

The stop-bar D may be provided with asuitable pump, G, the cylinder or chamber g of which has a pipe-connection, g', with the oil- Well A2, another pipe-connection, g2, with the bearing C, and a piston, g3, one end of which extends beyond the rear face of said bar D and abuts against or contacts with the end b of axle B, and has a reacting spring, 9*, to maintain such contact, as indicated in Fig. l..

The pipeconneotion g leads into an oil reservoir or pocket, c, formed in the under side of the brass or bearing C at any suitable place therein, or as shown in either Figs. l or 2. The pipe-connection g' is provided, either in the chamber g or elsewhere, with a checkvalve, g5, for preventing return of oil to Well A,

The operation is as follows: As the car travels along, the end thrust or movement of the axle, acting in conjunction with the spring g4, reoiprocates the piston g3, for pumping oil from well A2 to the brass or bearing pocket c, for lubricating the same andthe axlejournal. The end-thrust of the axle is limited by its end striking the bar D, at which time the piston g3 is wholly within chamber g, so that neither it nor its spring g* is subject to the hammering action of the end b of the axle against bar D, and they therefore do not rapidly Wear or ICO otherwise deteriorate. The piston g3 and spring may be constructed either as shown in Fig. l or 2 or otherwise, as desired. Vhen repairs are needed for the pump or replacement of a Worn-out pump by a new one is necessary, the axle-box lid is opened and the bar D and pump are removed for effecting said repairs or replacement, and this is accomplished Without dismounting or disturbingthe axle-box journal and bearing or other parts of the same.

It is obvious that the pump G on barD may be dispensed with and the latter be used as a stop-bar for limiting the end-thrust of the axle, as heretofore.

Instead of slotting the end d of bar-D,it may be solid, in which case a slot is then provided in lug a, as shown in Fig. 6, the rib ce2 on lug a3 being then dispensed with. If desired, however, both the slot d2 in bar D and the rib a2 on lug as may be dispensed with, as shown in Fig. 8, in which case the lug a3 has top and bottom edge iianges for retaining the bar D in locking engagement therewith. Again, if desired, the lug a5 need not be used, in which case the rib a2 is extended out and provided with a slot for the key, wedge, or bolt f, as shown in Fig. 9. These many last described modifications are shown and described to indicate that different ways of maintaining or locking the stop key or bar D in position within the axle-box, so that it can readily be removed at any time, may be employed; and I therefore do not limit myself to any one form of fastening or locking devices for said bar or key D, nor to any particular construction of pump, nor to putting the pump upon a removable stop bar or key, as it is evident that the pump may be otherwise mounted to be operated by the end-thrust of the axle.

What I claim is- 1. In an axle-box, the transverse stop bar or key D, located in front ofthe end ofthe axle and having supports on the sides of the box, and locking devices for maintaining the bar in position so as to be removable from the box, substantially as set forth.

2. In an axle-box, the combination of a socket, a, on one side of the box and lugs on the opposite side of the box, a bar, D, engaging with said socket and lugs, and a locking key or bolt engaging with said lugs and bar, substantially as set forth.

3. In combination with a caraxle box and axle, a stop key or bar provided with a pump operated by the end-thrust of the axle to elevate oil from the oil-well of the box to the axle brass or bearing, substantially as set forth.

4. In combination with a car-axle and box,

astop key or bar having a pump provided Y with a piston having a reacting spring operated by the end-thrust of the axle, as and for the purpose set forth. Y

5. The combination, in an axle-box, of an axle-journal, a brass or bearing, a stop key or bar having pump G, apipe-connection between pump Gand said brass, and a pipe-connection with the box oil-Well, and said pump being located and arranged to be operated by the end-thrust of the axle, substantially as set forth.

6. As a new article of manufacture, a stop bar or key for car-axle boxes having a pumping attachment, substantially as set forth.

7. The bar D, having chamber g, pipe g2, pipeg, with checlevalveg, and piston g3, projecting beyond one side of said bar and having a reacting spring, g4, substantially as set forth.

In testimony whereofI afx my signature in presence of two witnesses.

GEORGE F. GODLEY.
