CAR-AXLE BOX.l

SPECIFICATION forming part of Letters Patent No. 238,280, dated March 1, 1881. Application filed August 23, 1880. (No model.)

To all whom it may concern:

Be it known that I, E. RICHARD EsMoND, of New York, county and State of New York, have invented a certain new and useful Improvement in Gars, of which the following is a speciiication. l

This invention relates to that class of journal-boxes and pedestals for four-wheel cars in which the journal-boxes are fitted to move vertically between the horns of the pedestals, with saddles setting on the boxes and carrying springs at their lower ends, arranged in the interior of the pedestal-horns, and upon which the car-body rests.

It consists in making the part of the saddle over the journal-box rounded to it into circular supports or bearings on the top of the box, and the lower ends rounded to tit into circular recessed spring-seats under the springs, so that the journal-boxes, with the axles and the pedestals secured to the car-body, are free to move laterally relatively to each other, the

lower ends of the saddles moving with the pedestals and car-body at points which would be the centers of their rounded lower ends,

and the upper parts of them moving with the boxes and axles at a point which would be the center of theirrounded upper parts fitting into the circular supports on the top of the journalboxes.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of the wheels and part ofthe pedestal-timber of a four-wheel car, showing one of the pedestals and its saddle in section. Fig. 2 is an end view of a pair of wheels, their pedestals, and boxes, with one of' the pedestals in section, cut through the line x x, Fig. l; and Fig. 3 is an enlarged transverse sectional view cut through the jaw of the pedestal.

The pedestal a, is constructed and secured to the pedestal-timber b, which forms part of the frame of the car-body,in the ordinary manner. The axle-box c slides freely vertically and laterally in the jaw of the pedestal a, between the pedestal-horns of, and, with the exception of the circular recessed support or bearings'c, formed on its top, and the absence of lugs to prevent transverse movement in the pedestal-jaw, is of the ordinary construction.

d d represent the wheels, and c e the axles.

' In the circular recessed supports or bearings c on the top of the axle-box c rests the upper part of the saddle f, which is rounded so as to iit therein. The vertical parts of it hang down against the sides of the axle-box c, and are free to assume angular positions laterally to the axle-box. The lower ends, f', of the 'sides ot' the saddle are bent at right angles to the vertical sides and lit over the spring guidebolts g g,whicl1 pass vertically through the center openings of the horns a of the pedestal a. The holes in the ends f f of the saddle, through which these bolts pass, are enlarged sidewise to allow the saddle to rock thereon, as shown in Fig. 3. g

The car-body is supported on the bent ends f f of the saddle f, through the medium of the springs h h, which surround the guidebolts g g and rest in the spring-seats The under sides of these spring-seats have circular recesses formed therein to correspond to the rounded upper sides of the bent ends ff of the saddle f.

The axle-boxes are prevented from getting out of the jaws of the pedestals, when the weight of the car-body is by any cause taken off the springs and saddle, by means of the jaw-bits 7c being bent up into the jaws of the pedestal, as shown at Fig. 1, so that the bottom of the box cornes in contact with the bentup portion of the jaw-bits lo, while the springs h h are under compression between the bent ends of the saddle j' and the under side of the upper part of the pedestal, thereby keeping the saddle in the circular bearings on the top of the boxes by the downward pressure of the springs on the saddle.

l do not confine myself to lat-eral circular bearings, as the same may be made knife-edge bearings, if desired.

I am aware that the axle-boxes of cars have been connected to the frame or body of the car by means of suspensionlinks, (as illustrated in 'the United States Letters Patent to J. Eccles, No. 169,792, dated November 9, 1875, and R. Winslow, No. 115,261, dated May 23, 1871,) so I do not claim, broadly, such suspension of the car-body to the axle-boxes; but,

What I claim, and desire to secure by Letters Patent, is-

1. The saddle f of a car-axle box, constructed,

substantially as described, to rock at its lower vand through which pass the spring guideends in the horns of the pedestal a, and at its bolts g g, the guide-bolts g g, and the pedestal upper part on the top of the box c, in combia, substantially as and for the purpose hereinnation with the axle-box c, free to slide inthe before set forth. 15 5 jaw of the pedestal both vertically and later- In testimony whereof I have hereunto set ally, `as and for the purpose hereinbefore set my hand this 14th day of August, A. D. 1880. forth. 1

2. In combination, the axle-box 0, provided L' RICHARD ESMOND' with the bearings o c', the saddle f, round at Witnesses: 1o its central portion and at its supporting ends, JOHN D. SHEDLOGK, which are at right angles to its hanging sides, H. D. WILLIAMS.
