' IO rangement of springs for resisting the longitudinal thrust of the axle, and to the construction and arrangement of oilvreceptacles for lubricating the journals, as hereinafter fully described, and illustrated in the accompanying drawings, in which- Figure 1 is a vertical longitudinal section,

showing the parts in position within the box. y

Fig. 2 is a vertical cross-section on the line'z e, Fig. l. Fig. 3 shows the dust-shield 'detached, partly inside view and partly in section. Fig. 4 is a vertical section thereof. Figs. 5 and 6 illustrate a modiiication. A

Similar letters indicate correspon ding parts.- The letter A designates the body of an axlebox, and B the journal of a car-axle, entering the box through the usual opening, C, in the rear end thereof. Said opening C is closed, to prevent the entrance of dust, &c., to the axlebox, by a shield, I), which slides into arecess, 3o E, at the rear end of the box, and surrounds the body of the axle at that place, the shield being putin place prior to the introduction ofthe axle. This dust-shield is composed of a diaphragm, F, of cloth or other iiexible material, and oi' a rigid frame, G, supporting the diaphragm, the latter being attached to the frame in such a manner that it is expansible, andl thus adapts itself to the motions ofthe axle-box. 4o In the diaphragm F is an opening, H, to receive the journal, and at a distance from the edge of this opening the diaphragmv is provided with a rigid ring, I, so that such edge takes the form of a flange, u, projecting Vinward from the ring. vSaid flange u thus is the part of the diaphragm which is in contact with the axle, and, due to its `iiexible nature, the flange readily adjusts itself to the diameter of theV axle, thusalways preserving a tight joint 5o therewith. The material composing the dial phragm is doubled, andthe ring I is attached thereto between its two layers bylines ofstitching, t, O11 opposite Sides of the ring, whereby the ring is securely held in place, and, moreover, is concealed or protected.

O11 the ring I is an inwardlyprojecting flange, "J, of felt or other similar material, which is formed by bending a strip of the desired material upon itself around the ring, and which is substantially iiush with. the edge of 6 journal-opening H, it being interposed, like the ring, between the layers of the diaphragm, so that by this flange said edge of the journalopening is re-enforced, and obtains a superior .body or fullness, tending to improve its effect. 6

The frame G of the -diaphragm is divided l centrally and in a vertical plane into two parts or sections, G G, which are connected together by telescopicA tubes K, one at the top and one at the bottom of the frame, so that the frame-sections are movable toward and away from each other, and permit the adjustment of the frame in width to the recess E oftheaxlebox. In Order to render said frame G self-adjusting, a spring, N, is interposed between the 7 ends ot the frame-sections in both tubes K, this spring thus acting on both sections with a tendency to force the same away from each other.

For the purpose of resisting the longitudinal 8 'thrust of the car-axle in the mot-ions of the axle-box, I use, in lieu of the usual end ange, a "spring, O, which is arranged in the box in the proper manner to act on the end of the axle-journal. Said spring O bears' O11 a 8 washer, I, which in turn bears on the j ournal at the proper point, and, to support as well as protect the spring, it is inclosed in a casing, Q, which is attached to the cap Q ofthej ournal, it being in this example made in one piece therewith. This casing Q is open at the inner end, where it faces the journal, and is provided at that placewith a recess, s, adapted to receive the washer P, it being closed at the outer end. In the center ofthe spring O, which is 9 in this example aspiral,is situated a screw-bolt, R, the head of which is sunken into the face of the washer P, and which extends through the closed end of the casing Q at the free end, where it is provided with a nut, R, so that by I properly adjusting this nut the tension of the spring can be increased or diminished. Then it is desired to remove the spring and its'concomitants from the axle-box, the nut R' is tightened to draw the washer into the recess s and out of' contact with the journal, while, when the parts have been replaced in the box, the nut is loosened to allow the washer to resume a normal position, as shown in Fig. l, and in any motions of the box which may then takevplace the washer plays in and outward in the recess.

If' desired, the spring O may be duplicated, as shown in Fig. 6, and in that case the washer P is common to both springs.

The bottom A of' the axle-box is detachable, and supports an oil-receptacle, S, fitting into the box, such receptacle and the detachable bottom being integral or in 011e piece. In the top of the oil-receptacle S are a series of holes, into which are itted tubes T, thelatter resting in said top by means offlanges on their upper ends, and containing wicks U for conveying the oil from the oil-receptacle to the journal.

Said wicks U are sustained in a working position by means of spiral springs U', one to each wick, whicll surround the wicks and rest on flanges T', projecting inwardly on the lower ends of" the wick-tubes. By the arrangement of the wick-springs U on the flanges T, the wicks are left free below the lower ends of the wick-tubes, which latter terminate above the bottom. of the oil-receptacle, and the-proper absorption of the oil by the wicks is insured.

For the purpose of' securing the detachable bottom A of the axle box, I make use of screw-bolts V, which vextend through spiral springs IV, arranged in vertical passages Xin the side walls of the box, and which rest on the springs by means of their heads while they extend through said bottom at the free ends, where they are provided with nuts V. These nuts'V are fitted to recesses Y, which are formed on the bottom of' the box, in this example, by parallel ribs cast to said bottom, and when it is desired to tighten the nuts the bolts V are drawn downward against the tion of' the springs IV to bring the nuts out of l the recesses, while if, when the nuts have been set,l the bolts are released, the nuts re-enter the recesses and are firmly held therein by the action of the springs, so that they are not liable to work loose.

In some cases the spring-casing Q may be omitted and the spring O arranged between the end of the journal and the front side of the box, with or without a support, and in that event a wedge, O, Fig. 5, may be arranged between the spring and said side of the box, for regulating the tension of the spring.
