JERSEY, A CQRPORATIQN or MOUNTING FOR GAR-AXLE BOXES.

Application filed August 2,

To all whom it may concern: 7 i Y e it knownthat I, JAMES E. BUSHNELL, a citizenof the United States, residing at Cold Springs, county of Putnam, and State of New York, have invented certain new and useful Improvements in Mountings for Car-Axle Boxes, fully described and represented in the following specification and the accompanying drawings, forming a part of the same. y

The present invention relates to certain improvements in the mounting for car axle boxes set forth in my application No. 382,318 filed May 19, 1920, for patent on car axle mountings.

ln that prior construction the car axle boxes were secured upon a channel-bar near its opposite'ends, and were held at the desired distance apart by the projection of wings upon the boxes into notches cut in the flanges of the channel-bars.

It is the object of the present invention to avoid the labor of cutting such notches in the channel-bars, and at, the same time to provide means for holding the boxes securely to thebars, and preferably with clearance between the parts, to permit the selfadjustment of the boxes in line with the axle.

These objects are attained by securing to the bar-flanges at opposite sides of each box, housings which have sockets to engage wings on the box and hold the box to the channel-bar while permitting self-adjustment of the boxes.

The wings are offset toward the lower side of the box so as to clear the flanges of the channel-bar when fitted into the housings.

The housings may be variously constructed to engage the wings detachably, so as to facilitate the assembling of the parts and the separation of the same when required for repairs.

To illustrate this feature two constructions are shown in the annexed drawing, in which the car body is omitted, and only the box-mounting isshown. I

Figure 1 is a perspective view of a channel-bar with one of the axle-boxes fitted thereon, and the housing forked or open at the lower side; Fig. 2 is an inverted plan of the parts shown in Fig. 1; Fig. 3 is a cross-section of the channel-bar shown in Fig. 1 online 3-3 in Fig. 2; Fig. 4 is a Specification of Letters Patent;

Patented Oct. 12, 1920. 1920.- Serial No. 400,672. i

View like. Fig. l with one side; and Fig. 5 is across-section of the same at one edge of the socket in the housing.

The channel-bar is formed of a plate a with flanges a at its edges; these flanges stiffen the plate and afford attaclnnent of the housings to the bar.

designates the car-axle, with a carwheel C upon one end. For want of room upon the drawing, the car-wheel is omitted from the opposite-end.

The body of the axle-box is designated D, and its upper part is fitted between the flanges a, and provided with a-seat 7) to rest or bear upon the plate a. Such seat ismade convex on top, crosswise of the box, so as to rock lengthwise, to adjust itself to the axle and plate simultaneously.

lVings 0 are projected from the sides of the body D, below the level of the flanges a, and the housings are attached to the outer sides of the flanges to embrace these wings, and hold the box from longitudinal movement.

The housings have each a foot-plate ctattached to the flanges a by rivets cl, and an arm or arms extended downward from the edge of the flange to form the sockets which loosely embrace the wings.

In Figs. 1 to 3 the housing is formed with two arms it having a socket E between them to receive the wings of the axle-box.

the housingopen at In these figures, the lateral thrust on the box is resisted by lugs or. ears 6 projected from' the sides of the body nearly to the flanges.

' The box and its wings and lugs are constructed, as shown at e, to clear the flanges a and housings h, 72. to permit the boxes to adjust themselves automatically to the axle. This construction avoids the necessity of any mechanical adjustments, or the proyision of any movable parts to effect adustments.

A lock-bar f is attached to the ends of the arms h and touches the under sides of the wings to lock or retain the wings in the housings.

The lock-bars are held in place by crossbolts 9 which pass through the arms and lock-bars, .and extend below the body of the box; thus supporting it firmly.

. The box can be taken from the channelbar by withdrawing the bolts and removing the lock-bars.

The housings sustain the wings beneath the flanges a and hold the boxes firmly from end thrust, without outting'into the flanges to form a transverse shoulder.

In Figs. 4 and 5 the housing is open at one side and each wing is held in placeby the horizontalarm if of the housing alongthe lower side of thesocket E. I

The vertical arm k of the housingresists end-thrust upon the axle, and end-support in both directions is secured by applying the housings to the opposite ends of channel-bar in reverse positions. 1

In Fig. 5, the seat I) on top of the body D is extended nearly to the inner sides of the flanges a to resist lateral thrust, and the Wings 0 are extended out from the ends of the seat to project through thehousings. r

With both the constructions of Figs. 1 to 4 the end-thrust is sustained without notching the flanges a.

With both of the constructions showman eflicient support and self-adjustment otthe axle-boxes are secured with the use of ordinary channel-bars and rough-castings, thus 'PIOClHClIlg a very cheap construction.

Having thus set forth the nature of the invention what is claimed herein is:

1. Ina car-axle mounting, the combination, with a channel-bar, of housings secured to the flanges of the bar, and axleboxes arranged between the flanges, and having wings projected outward through the said housings.

2. In a car-axle mounting, the combination, with a channel-bar, of housings secured to the flanges of the bar, and axleboxes arranged between the flanges and having Wings projected outward through the'housings beneath the said "flanges.

V 3. In a car-axle mounting, the combination, witha channel-bar, and axle-boxes arranged between the flanges and having wings extended outwardly, of housings attached to the outer sides of the'flangesiand socket open at the bottom, and one of the wings fitted thereto, and a lock-bar connectlng the arms below the wing and secured by bolts through the arms and lock-bar.

6. In an axle-box mounting, the combination, with a channel-bar, of housings secured to the flanges of the bar, and axle boxes fitted between the flanges, and having each a convex seat fitted to the plate of the channel-bar, and extended nearly to the flanges 'to resist side-thrust, and having wings extended beyond the ends of the said seat and embraced by the said housings;

In testimony whereof I have hereunto set my hand.

JAMES E. BUSHNELL.
