RAILWAY-CAR-TRUCK PEDESTAL AND JOURNAL-BOX.

Application led July 12, 1920.

T 0 all w hom t may concern Be it known that I, DANIEL IV. ALBER- MAN, a citizen of the United States, and a resident of the city of Chicago, inthe county of Cook and State of Illinois, have invented a new and useful Improvement in Railway- Car-Truck Pedestals and Journal-Boxes, of which the following is a full, clear, and exact description.

My invention relates to improvements in journal boxes and pedestals for railway car trucks, and it consists in the combinations, constructions, and arrangements herein described and claimed.

An object of my invention is to` provide a journal box and pedestal having means for reducing the wearing of the one upon the other to a minimum.

A further object of my invention is to provide a journal box and pedestal of the type described, having larger bearing surfaces contacting each other than is ordinarily provided.

A further object of my invention is to provide a device of they type described that is stronger and more durable than any heretofore provided.

Other objects and-advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which- Figure l shows the journal box and pedestal assembled on a truck,

Fig. 2 is a rear elevation of the journall box and pedestal,

Fig. 3 is a side elevation of the journal box and pedestal, and

Fig. 4 is a section taken along the line 4 4 of Fig. 2.

In carrying out my invention, I make use of a standard truck.having a frame 1, to which six of my pedestals 2 (one shown) are secured by bolts 3. One of my journal boxes 4 is slidably disposed in a guideway 5 in each of the pedestals 2. The pedestals 2, carrying the journal boxes 4, are located on each side of the frame 1, one in the center and one at each end of the frame 1. A pedestal strap 6, secured to the frame 1 at one of its ends by the bolt 7, passes under the bottom of the three pedestals 2, and is secured at the other end of the frame 1 by a bolt (not shown).

Specification of Letters Patent.

disposed in the slots 8 Patented J an. 11, 1921. Serial No. 395,642.

Each pedestalA 2 has a slot 8 running through its'center, parallel with the length of the frame 1. 4The slot 8 intersects the transverse guideway 5. An equalizing bar 9, situated between two of the pedestals 2, is of both pedestals and rests on the tops of-the journal boxes' 4. The equalizing bars 9 are bent downwardly between the pedestals 2 and support the usual equalizing spring. A truck side bearing. 12 is connected to each truck bolster 12 which bears on the elliptic spring 11. The

I ouinal boxes 4 are carried by the axles 13 on which the wheels 14 are mounted. The parts thus far described are built in conforinitv with the usual practice and, with the exception of the pedestal 2 and the journal box 4, form no part of my invention, except in so far as they coperate with the journal box and pedestal.

, A description of one of my improved journal boxes and pedestals will sufiice, as all are precisely identical in construction.

The pedestal 2 has end portions 15 and 16 which are spaced from each other by horizontally disposed bars 17 and 18. The bar 17 is spaced from the tops of the end portions 15 and 16, thus forming a groove 19 in which the frame 1 is adapted to be disposed. The bar 18 is* also spaced Afrom the bottoms of the end portions 15 and 16. The slot 8, parallel with the end portions 15 and 16, is provided between the bars 17 and 18, and the end portions 15 and 16. The guideway 5, extending transversely through the pedestal 2, terminates at the under side of the bar 17. A pair of vertical outwardly extending vlugs 20 and 21, integral with the end portion 16, are spaced from and parallel with the outer edges of the guideway 5. A second pair of vertical outwardly extending lugs 22 and 23, integral with the end portion 15, are spaced from and parallel with the opposite edges of the guideway 5.

The journal box 4, horizontally disposed in the guideway 5, has vertically extending recesses 24 and 25 in its opposite sides. The lateral edges 26 and 27 of the two rencesses 24 and 25 respectively slidably engage the outer faces of the end portions 15 and 16. A pair of vertically extending guides 28 and 29, integral with the journal box 4 and disposed in the recess 24, are adapted to slidably engage the inner faces of the end portions 15 and 16. A second pairl of vertically extending guides 30 and 31, integral with the journal box 4 -and disposed in the recess 25, are adapted to slidably engage the inner faces of the end portions 15 and 16. A pair of vertical outwardly extending lugs 32 and 33, adjacent to the edges 26 and 27 of the recesses 24 and 25 respectively are integral with the sides of the journal box 4 and adapted to slidably engage the lugs 20 and 21 of the pedestal 2`. A second pair of vertical outwardly extending lugs 34 and 35, adjacent to the opposite edges 26 and 27 of the recesses 24 and 25 respectively, are integral with the sides of the journal box 4, and adapted to slidablly engage the lugs 22 and 23 of the pedesta 2.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The passenger car is resiliently supported by the parts described. As the car moves over the track, the unevenness of the road bed is taken up by the vertical movement of the pedestal 2 in the journal box 4. Due to the lurching of the car, caused by curves in the track, the journal box bears laterally and longitudinally against the pedestal 2. The lateral movement of the journal box against the pedestal 2 is limited by the guides 28, 29 and 30, 31 bearing against the inner faces of the end portions 15 and 16 of the pedestal 2, and by the edges 26 and 27 of the recesses 24 and 25 bearing against the outer faces of the end portions 15 and 16 of the pedestal 2. The longitudinal movement of the journal box 4 against the pedestal 2, formerly limited only by the sides of the guideway 5 of the end portions 15 and 16, is, in my device, limited also by the lugs 20, 21 and 22, 23 of the outer faces of the end portions 15 and 16, contacting with the lugs 32, 33 and 34, 35 respectively of the journal box 4. Thus the wear of the journal box 4 upon the pedestal 2 is reduced to a minimum, due to the large bearing surfaces contacting one another, and the life of both articles is prolonged.

It is obvious that many modifications and adaptations of the form of the device pictured in the accompanying drawings may be provided without departing from the spirit and scope of my invention.

I claim:

1. In a railway car truck, a pedestal, having a vertically extending guideway therein, said pedestal being provided with pairs of oppositely extending lateral lugs positioned adjacent the edges of said guideway, and a journal box slidably disposed in said guideway, said journal box being provided with guide lugs abutting against said first named lugs, whereby lateral and longitudinal movement of said journal box in said pedestal is reduced to a minimum.

2. In a railway car truck, a pedestal having a vertically extending guideway intersected at its center by a transversely extending slot, said pedestal being formed with pairs of lateral lugs positioned adjacent the outer edges of said guideway, and a journal box slidably disposed in said guideway, said journal box being provided with guide lugs extending within the intersecting slot for limiting lateral movement of said j ournal box and with projecting guide lugs abutting against the lugs provided on said pedestal, whereby longitudinal movement of said journal box in said pedestal is reduced to a minimum.
