CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 375,217, dated December 20, 1887.

Application filed February 12, 1887. Serial No. 227,392. (No model.)

To all whom it may concern:

Be it known that I, JAMES J. STEVER, a

citizen of the United States, residing atOwosso,

in the county of Shiawassee and State of Michigan,have invented certain new and useful Improvements in Oar'Oilers, of which the following is a specification.

Heretofore in the oil-boxes of railwaycar axles it has been customary to pack within the box a quantity of saturated waste, the said waste being so arranged around the bearing of the axle that loss of oil or lubricating material was unavoidable, inasmuch as there is nothing to prevent the oil from running out at the rear side of the journal-box. As the result of this, the oil spreads out and flows along the axle until it comes to the wheels, at which point it commences to drip, entailing an enormous loss of valuable on;

Another drawback to the ordinary means of oiling the bearings of car-axles is that the jar of the cars causes the waste and oil in the jour= nal-box to drop down and away from the axle, and as soon as it settles and falls away from the bearing the axle will become dry and heated, and the friction generating will set the waste and oil on fire. This has often occurred and is the immediate cause of great loss in railway property.

To obviate these drawbacks and to provide a simple, effective, and automatic oiler for the bearings of railway-car axles are the objects of my invention;

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is a plan view of my invention. Fig. 2 is a longitudinal section of a journal-box with my invention applied. Fig. 3 is an end ele vation without the journal-box, the journal being in section.

Ais an axle having a bearing-surface formet on its journal B, and O is thejournal-box, in which the oil is held.

D is a frame provided with lugs E, which form bearings for a pin or pivot or hinge, F. Arms or levers G are journaled to this pivot, and these arms or levers constitute a frame having a pin, H, connecting their upper extremities, said pin H forming the axle or shaft of a rotatable wheel, J, having centrally-lo cated incisions K upon its periphery, thus forming a roller with a centrally corrugated under the cross-piece N of the frame G, andserves to support said frame at an angle, as shown in Fig. 3, and by this means keeps the wheels J against the bearing B of the axle. As the axle rotates it will bear upon the peripheries of the wheel J, which movement will cause them to rotate also, and as the oil is located in the bottom of the oil-box the wheels J as they rotate will carry the said oil to the bearing-Snrface of the axle by means of the indentedportions K. By this means the bearing-surfaces are kept constantly oiled,and the springs, keeping the rotating wheels against the axle, will lubricate the bearings as long'as there is oil in the box. I also provide a stop or collar, S, having shoulders at both ends, which slide on uprights T, said collar being also provided with a supportingspring, U, for the purpose of keeping it con- Stantly against the bearing of the axle, and thus preventing any oil from passing in that direction and'toward the wheel. It will thus be seen that any oil that has passed as far back as the collarS will be turned back into the j ournal-box again, and thus all waste from this source is prevented.

I am aware that it has been proposed to cushion beneath a journal rotatable rollers provided with corrugations, and the same being fluted throughout their'length for convey ing the lubricant to the journal; but this is not the equivalent of my invention, nor do I wish to claim the same. In my invention the corrugations only extend a portion of the way across the periphery of the roller, thereby leaving a plain surface on each side,which portion bears against the journal and prevents the cushion-springs from subjecting the journal to pressure against the sharp edges of the corrugations,

Therefore, what I claim as new, and wish to secure by Letters Patent, is-- l. The combination of the base-frame D, having paired lugs E E,-E E, pins F, supported in the lugs, inwardly-extending frames and a spring, V, secured to the base-frame and having arms G G, G G, and eross-bars N N, supporting the collar, substantially as de- [0 rollers J J journaled in the ends of the arms, scribed.

and the springs L L, secured to the base-frame no 4 5 and bearing on the cross-bar, substantially as JAMLD STDVER' described. Vitnesses:

2. The combination of the base-frame D, up- I. J. STEVER, rights T T, collar S, sliding on the uprights, FRANK E. COOK.
