IMPROVEMENT IN CAR-AXLE BOXES.

Specification forming part of Letters Patent No. 158,358, dated January 5, 1875; application led August 17, 1874.'

To all whom it may concern:

Beit known that I, TnoMAs H. BURRIDGE,

of St. Louis, St. Louis county, Missouri, have,

invented a certain new and useful Improvement in Oilers for Oar-Axles, of which the following is a specification:

This is an improvement and simplification of my device for oiling railway-car axles, for which Letters Patent of the United States were granted t0 me on the 2d day of June, 1874, and numbered 151,562.

My patented device consists of a single pad and counter-balance, mounted on a shaft below the axlejournal, and oscillated by means of suitable gearing connecting it with the axle, so as to periodically immerse said pad in the lubricant in the bottoln of the oilbox.

In the present device I dispense with `the gearing mechanism, and add features which are new in construction and operation.

This improvement consists in a rocking frame, supported in the oil-box beneath the axle, and carrying' at the ends pads, which, as the box is shaken, (by the movement of the car,) are thrown up alternately against the underside of t-he axle-journal. Depending from these pads are beards of cotton wicking or other brous material, to supply oil to the pads by capillary attraction. When the oil is low in the box these beards still carry up a sufficient quantity of oil to lubricate the journal. To each pad is attached au ear, having an eye, into which may be hooked a weight, to counterbalance any redundancy of weight in the other pad, and which would otherwise interfere with the regular rocking of the frame.

In the drawings, Figure l is au end view of the axle and oiling device within the oilbox. Fig. 2 is a top view of the oiler, showing parts broken away to exhibit construction. Fig. 3 is a side elevation of the axlejournal and oiler in position in the oil-box, which latter and the journal-box are in section.

A is the oil-box. B is the journal-box. C is the axle, and D the axlejournal. The oiler-frame has an arm, E, secured by a bolt, screw, or rivet, F, to the side of the oil-box.

To the arm E is attached a plate, G, lying on the bottom of the oil-box, and supporting two uprights, H I. K is a rock-shaft, with bearings in the tops of the uprights H I. The shaft K is preferably made removable by the following` means-one end is first inserted endwise into the upright I, and the other end is then dropped into the open-topped bearing in the top of the upright H, and is held down by a hook, L. M M are arms, extending from opposite sides of the rocksbaft, and carrying at their ends cross-arms N N, upon which are secured the perforated pad-plates O O.

The arms M M pass through the crossarms NN, but the joint is preferably made so loosely thatthe cross-arms have freedom to turn upon the arms M M a limited distance to either side, to accommodate the surface of the pad to the journal' in cases where the oil-box is not straight with the journal, or the oiler is not in proper relative position with the journal, from any cause.

Through the perforations in the plates O O pass cotton wicking or strings of other fibrous material, P, whose ends or loops p hang down to the bottom of the oil-box, so as to take up oil by capillary attraction, and cause the saturation of the part of the material above the plate, and which forms the lubricating surface of the pad. The upward flow of oil in the hanging ends p is aided by the ilexure of the ends caused by the rocking of the shaft K.

The lower ends of the cross-arms N N extend downward, and form-ears n a, which are perforated to receive the suspension-hooks of a weight, It, whose office is to counterbalance any inequality in weight between the two pads, and to thus overcome the tendency of either pad to remain in constant contact with the journal. The weight is of course suspended from the lighter pad, so as to give it an equal weight with the other.

The arrangement is such that the shaking of the oil-box, when the cars are in inotion, will oscillate the pad-frame, so as to bring the pads alternately in contact with the journal.

I claiml. The 1ubrieating-emdle K M N O I?, hav- Vituess my hand this 10th day of August, ing bearings H I, in combination with :u1 A. D. 1874i.
