k Application filed November To all whom it mdy concern:

Be it known that I, JACOB J. BYEns, a resident of Chicago, in the county'of Cook and State of Illinois, have invented a new and useful Improvement in Car-Trucks, of which the followin is a full, clear, and exact description, re erence being had to the accompanying drawings, forming part of this specification, in which.

F i ure l is a side view of a portion of the side rame and one, of the journal boxes of a car truck and illustrating my invention; F ig. 2 is a section on theline II-II of Fig.

1; and Figs. 3 and dare views similar to Figs. 1 and 2, respectively, but showing a modification. I a

My invention has relation to car trucks, and more particularly to means for securing .the journal boxes to the side frames, the

object of my invention being to provide a simple and convenient securing means whereby both vertical and horizontal movements of the boxes with relation to the .side frame are revei'ited, and which is provided with asaleguard for holding the parts in proper relation, in. case the securing nuts should become loose or workoff.

Referring to the drawings, the numeral 2 designates the side frame of a car truck. which is provided at the end with an overhung extension 3 to receive the journalbox 4, the under side of this extension being provided with a horizontal bearing face 5, for the top of the box and the end of the side frame preferably being provided with a bearing face 6, at substantially right angles to the bearing face 5, and thebox fitting in the angle between these two faces.

7 is a strap bolt by means ofwhich the box is secured to the frame. This bolt extends downwardly through the end of the overhung extension 3, around and underneath the box, its lower end being provided with a head 8, and its upper. end being provided with a threaded portion 9, to receive a holding nut 10. Inasmuch as the nut 10 may, in practice, become loose or work ofi,

Specification of Letters Patent. Pate ted June 20, 19131.

10, 1910. Serial No. 591,734.

l in order to hold the parts in secure relation in such a case, I provide the bottom. of the box with an eye 11,.through which the lower horizontal-arm of the bolt is passed. In this manner, the parts are held securely in' place, notwithstanding the looseness or loss of the nut 10.

The box is shown as having lateral and bottom flanges 19, forming a groove to reis convexed, the strap bolt being bent to conform to the curvature of the lower outer portion of the box, so that when the bolt is tightened, it tends to draw the box both upwardly and also inwardly into contact with the bearing faces 5 and 6, thus preventing any looseness;

In Figs. and 4, I have shown a modification in which the strap bolt 7 is of flat form, with rounded end portions. In this form, the bottom of the box is formed with a retainer 14- for the strap bolt. This re tainer is shown as formed by thelugs 15. It will be obvious that the strap bolt-may be of various forms, and that the retainer therefor may be formed in various other ways. 7

Features of my invention which are herein shown but not claimed form the subject matter of another pending application.

I claim: 1. A journal box for car axles having a to prevent dropping away of the securing device, substantially as described.

2. In a car truck, a side frame having a seat for a journal box open at one side and at the bottom, a journal .box havinga retainer 'onits bottom portion, and a strap or boltpassing through said retainer and securing the box to the side frame, substantially as described.

3. In acar truck, a side frame having an overhung end portion, a journal box seating underneath the ove rhung portion and against the end of the side frame and havceive the strap bolt, and its lower portion 13 retainer at its lower portion to receive a securing device, said retainer being arranged With a retainer arranged to receive a securing device and hold it agaimt dropping 1) away; substantially as (i(,$-('1'l|)0(i.

In testimony )vhereof, I have hereunto set my band.
