SECIFICATION forming part of Letters Patent No. 534,369, dated February 19, 1 895.

I Application filed June 23, 1894- Serial No. 515,513' (N0 mDdGlJ Be it known that I, WILLIAM HYDE, a citizen of the United States, residing in the city of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Axle-Boxes, of which invention the following is a specication.

My invention relates to the improved axlebox described in Letters Patent issued to me as assignee of Robert Hyde, May 22, 1894, NO. 520,314.

The object of my invention is, first, to provide, in lieu of the spiral spring b described in said patent as being attached tothe link and as bearing directly on the cam, a spring whichA shall have equal capacity with said spiral spring to bear with uniform vertical pressure directly on the cam, while it shall be free from liability to suffer or occasion undue wear; second, to render more certain and secure the action of the spindle and cam in the work of raising the axle box aud. its load clear of the axle journal; third, to apply to the front opening of the axle-box a lid provided with a lug which, when the lid is drawn or pressed to one side for the purpose of opening the box, shall bear on the corresponding lug of the box with an amount of friction or pressure sufficient to hold the lid until it has been released by the application to it of exterior force.

In the annexed drawings Figure l is a vertical longitudinal section through the/middle of the box; Fig. 2, a vertical section of the same on the line l. l of Fig. 1 showing the link as it stands when not in use; Fig. 3, a similar view showing the link as in use, that is, brought down to a bearing on the axle; Fig. 4, a vertical section on the line 2. 2 of Fig. 1; Fig. 5, a plan of the box with the lids lug and the corresponding lug of the box in horizontal section; Fig. 6, a vertical section 0n the line 4, et. of Fig. l, showing the spindle,

' ratchet and spring pawl, on an enlarged scale;

Fig. 7, a perspective view of said spring pawl; Fig. 8, an inverted perspective view of a portion of the box wall showing one half of the recess or socket for the pawl; Fig. 9, a pei'- spective view of the box lug showing the inclined projections on its face.

Similar letters of reference denote similar parts in the several figures.

a represents a car axle, whereof b is the wheel seat; c, the dust-guard-bearing; cl, the journal, and e the collar.

f represents the axle-box; g, the lid covering the front opening of the box; h, a portion 'of the arch-bar; h', a portion of the inverted arch-bar; 72.2, a portion of the tie-bar; t', bolts and nuts for securing the axle-box between these bars; j, the dust-guard; 7o, the journalbearing; Z, the key; m, the link provided with lugs fn, which engage Vcorresponding lugs 0 0n the axle box, (see Fig. 5;) p, anaperture in link/m for the axle, said aperture being large enough to admit of the necessary movement of the link up and down, as required and also to let the link be clear of the axle, as shown in Fig. 2, when not in use.

q represents the spindle working in a recess s in the bottom of the box. The spindle q is supported by a cap t, Fig. l. Said c'ap may be conveniently formed by bending the tie-bar h2. The spindle q carries cani fu, at one end and is provided at its other end with a socket 'n to receive the head of a crank or lever.

Instead of the spiral spring (b) described close contact Vwith cam u, and also for holding the link up clear of the axle when said link is not in use for lifting, I make use 'of albar to provided with a groove in each end, the

Vrespective grooves being adapted to engage and slide upon and between the respective tongues or guides Said guides are located upon the sides of the opening z in link m. The bar w is caused to bear with acontinuing vertical pressure on cam u by means of the spiral springs y, the ends of which sit in recesses in the bar and link, as indicated by dotted lines in Fig. 2. I have found that this construction effects the results produced by the spiral spring (b) describedin said patent, and at the same time obviates wear.

I provide the spindle q with a ratchet ot and a pawl c. I` prefer to give the pawl c the construction shown. One end of pawl c occupies a recess or socket d; this end being provided with two lugs c2 which, when the pawl is being put into the socket slidein two similar open spaces or slots one of which c3 is shown in Figs. 6 and 8. Two similar tongues, one of which c4 is shown in these figures, de-

in said patent as means for holding link min IOO,

tain the pawl after its introduction, without interfering with its freedom of 1n ovement.

f represents a spiral spring one end of which rests in a recess g in the wall of the axle box and the other end in a recess 1l' in the pawl as shown in Fig. 6. The spring f insures engagement of pawl c with the ratchet. This construction enables me to use a longer lever and thus to exert more power for turning the spindle q and it also enables me to hold the box and its load securely at any height to which they may have been lifted and without loss of elevation, when the lever or levers are being shifted or manipulated.

The ratchet and pawl can be applied to the spindle at any point preferred.

Vhen the lid g of the axle box is made in the ordinary Way, described in said patent, it (when lifted up) obstructs the free use of the lever employed for turning spindle q. I provide the axle box with a lug j and the lid g with a lug 7.x', Figs. l, 4t, 5 and 9. The face o f the lugj is provided with two inclined projections l7'2 and the face of lug lr. with two correspondingly inclined projections 7a2.

m is a bolt passing through eyes in the lugs last mentioned and provided with a spring n and a washer o'.

p is a nut for securing bolt m in place.

Vhen the lid is closed the inclined projections 7a2 of the lid mesh with the similar projectionsj2 of the box lug and thus lock the lid in place. When, in order to open the axle box the lid g is pressed to one side, the inclined projections k2 of the lid and the corresponding projectionsj2 of the box, ride up on each other with increasing mutual pressure due to said inclines and to spring fn; this pressure being strong enough to hold the lid until released by the hand ot' an operator or by other exterior means.

I claiml. In combination with the axle of a railroad car, an axle box provided 'with a link capable of downward and upward movements, a spindle adapted to be rotated, a cam arranged on said spindle in engagement with said link and adapted to move said link down to bear on said axle, or to move it up to be said cam and being adapted to move between guides a: substantially as and for the purpose set forth.

2. In combination with the axle of a railroad car an axle box provided with a link capable of downward and upward movements, a spindle adapted to be rotated, a ratchet arranged on said spindle, a pawl adapted to engage said ratchet, a cam fixed on said spindle and arranged in engagement wit-h said link and adapted to move said link down to bear on said axle or to move it up to be clear of said axle, as required, and a spring connected with said link and adapted to bear uniformly with a continuing vertical pressure on said gam, substantially as and for the purpose set Orth.

3. In combination with the axle of a railroad car an axle box provided with a link capable of downward and upward movements, a spindle adapted to be rotated, a ratchet arranged on said spindle, a pawl adapted to engage said ratchet, a cam ixed on said spindle, and arranged in engagement with said link and adapted to move said link down to bear on said axle or to move it up to be clear of said axle, as required, and a composite spring consisting of the bar w and the spiral springs y, said bar bearing directly on said cam and being adapted to move between guides substantially as and for the purpose set forth.

4. An axle box having a lug j', the face whereof is provided with inclined projections f in combination with the lid ghaving a lug 7c the face whereof is provided with the correspondingly inclinedv projections 7a2, bolt m passing through eyes in said lugs, washer o', spring n arranged on said bolt for the purpose of keeping the faces of said lugs in close contact, and means for securing said bolt in place, substantially as set forth.

WILLIAM l-lYDE.
