CAR-AXLE Box.

SPECIFICATION forming part of y Letters Patent No. 371,243.1ated October 11, 1887. Application filed March 6,1886. Serial No.194,213. (No model.)

Saratoga, in the county of Saratoga and Stateof New York, have invented new and useful Improvements in Car-Axle Boxes, of which` the following is a specification.

My invention consists in providing the axlebox with an independent oil-supply chamber, from which the lubricant is automatically fed lo into the oil-chamber of the axle-box, the said oil-supply chamber being hinged to the axlebox and Iprovided with a fastening device, whereby it may be secured in such manner that access to the axle-box cannot be obtained by "chambehaving a suitable opening through which the lubricant will be automatically fed 'in the manner hereinafter set forth.-

In the accompanying drawings, which are 2o herein referred to and form part of this specification, Figure 1 is a longitudinal section of vmy car-axle box with the oil-supply chamber closed in position for feeding the lubricant to the axle-box; Fig. 2, a like section with the 2 5 oil-supply chamber turned back in position' for refilling it, and Fig. 3 a plan view of Fig. l. As represented in the drawings, A isaportion of a car-axle, one end only being shown; B, the axle-box; C,`the journal-brass; D, the 3o key for holding the journal-brass, and E the 4 oilsupply chamber.

The axle-box B is made substantially in the form shown in the drawings, with a cham oer, p b, for containing the fibrous o r other material by which thezlubricant is held and applied to the journalof the axle. l An opening, b is made in the outer end of the axle-box for the vpurposeof obtaining access to the chamber b. At thelower side-of said opening hinge-lugs b2v 4o are formed, and at the upper side of it bosses b3 are made to receive a fastening-bolt, as hereinafter set forth. A wopden slip, b, having an opening through which the axle A is passed,

is fitted to reciprocate guides at the inner end ofthe axle-box, the said slip being inserted for the purpose of preventing dust and dirt from entering the chamber b at that point.

The journal-brass Gis fitted to the journal of the axle A, and is held in place by the key D, which is interposed between the brass and the upper plate of the axle-box.

The oil-supply chamber E is fitted to close into the opening b of the axlebox. Said chamber is provided with a feed-opening, e', having a stopper, i5-'through which oil is fed into the supply-chamber. Saidchamber, when filled with oi1,is virtually airtight, the pressure of the atmosphere being sufficient to prevent the oil from escaping through the dischargeopening e3, exceptwhen the axle-box is subj ected to a j arring motion. When a thin freelyliowinglubricant is used, the opening e3 should provided wit-.ha loQsely-tting valve, et. so arranged that thejarring motion produced by the running of the car will give suiiicient movement to said valve to permit the required 'quantity o f oil to escape from the oil-supply chamber E into the chamber b of the axle-box to properly lubricate the axle. Vhile the car remains stationary the valve e4 will prevent the oil from dripping through the opening c,- but in cold climates, or when a thick and heavy lubricant'is used, the valve ei* may be dispensed With. as under such circumstances the atmospheric pressure will be found sufficient to prevent the lubricant from escaping from the oil 'supply chamber, excepting when the box is jarred by the cars while running.

The oil supply chamber E is hinged, by means of the hinge-pin e, to the hinge-lugs b of tlle axle-box', -so as to swing in a vertical plane into and out of the opening b. A boss, e5, corresponding to the bosses b on the axlebox, is formed on the upper part of the oilsupply chamber E, and an opening, f, through the said bosses is adapted to receive a fastening-bolt, F, which passes through all of said bosses, so as to secure the oil-supply chamber' E in' its closed position, as shown in Figs. 1 and 3. One end ofsaid fastening-bolt is provided with ahead, f', to prevent it from passing .through the openingf, and its opposite end has an opening for receivingalock, G,by which said fastening-bolt is secured in place.

y The vertical back plate of -the oil-supply chamber E, at the side nearest the end of the axle A, forms a. bearing to receive the thrust of said axle in its endwise play and to limit the extent of said play.

`For the purpose of filling, the oil-supply 5 chamber Eis turned over into the position shown in Fig. 2, and the stopper e2 is removed from the i'cedopening e', and through the lat ter the required supply of oil is poured into said chamber. When this is accom plished,the

xostopper e2 is restored' to its place, the chamber E turned back into the position shown in Fig.

1 and secured bythe fasteningbolt F, as shown in Fig. 3. The jarring motion incident to a cnr in motion -will suice to cause the needed x5 supply of lubricant to pass from the oil-charnber E into the chamber b of the axle-box, and in this manner the supply' of oil in thelatteris automatically replenished as occasion requires.

I claim as my invention- The combination, with a car-axle box, of an zo oil-supply chamber hinged to said box, provided with a fastening device, and having an automaticvalve in its b0ttom,which allows tlye escape of the lubricant into said axle-box only when there is a jostling motion ol' said b'x 25 and chamber, substantially as set forth;
