PEDESTAL.

SPECIFICATION formingpart of Letters Patent No. 700,894, dated May 2'?, 1 902.

Application filed February 26, 1901. Serial No. 48.970. (No model.)

To L7/Z whom, it muy concern:

Be itknown that I, PERRY BROWN, acitizen of the United States, residing at lVilmington, in the county of Newcastle, State of Delaware, have invented a certain newand useful Improvement in Pedestals, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in pedestals for railway-car trucks, and has for its object a simple form of pedestal which will so reduce the wear on the pedestal and the box supported therein that the objections to using malleable-iron boxes will be overcome.

Afurther object is the improvement of' the pedestal, so that in case the tie-rod should lose one of its bolts the end of the tie-rod would still be prevented from dropping or being bent down out of place.

l/Vith these main objects in view myinvention consists in the pedestal as shown in its preferable embodiment in the accompanying drawings and as will be now more partielllarly described and then definitely claimed at the end hereof.

In the accompanying drawingsvhich show my invention, Figure 1 is a side elevation, partly in section, of a pedestal and such parts of a railway-truck as are necessary to illustrate my invention. Fig. 2 is a horizontal section of the pedestal through the line of Fig. 1. Fig. 3 is an edge View of the lower portion of the exterior of the pedestal.

Referring now to the details of the drawings by numerals, 1 represents the pedestal, which is bolted, as usual, to the longitudinal timber 2 of the frame of the truck. This pedestal 2 has the usual downwardly-depending standards 3, between which works the journal-box 4, which may be of any desired construction. The standards 3 3 of this pedestal are secured together and to the standards of the companion pedestal or pedestals by means of the usual brace or tie rod 5. Instead of bolting this brace or tie rod 5 to the under sides of the pedestal-standards in the usual manner I form loops or pockets 6 6 on the lower ends of the standards 3, and the brace or tie rod 5 passes through these pockets and is secured therein by means of the bolts and nuts shown at 7 7. I consider this construction of the ends of the pedestal-standards 3 3 quite important, for the reason that if one of the bolts should be shaken loose or drop out the loop will hold the end of the tie-rod 5 in position untila new bolt can be placed in position.

Each of the standards 3 3 is formed of two flanged sides S and 9, connected by the web This latter instead of being carried up straight for a limited height, as is now the practice, is made of the peculiar shape shown in Fig. 1 and has two pockets 11 and12 for the purpose of holding antifriction-rollers 13 to reduce the wear between the pedestal and the sides of the box. These rollers 13 are held in position in the pockets 11 and 12 by means of bolts 14, passed through the bosses 15 on the sides S and 9 of the pedestal-standards 3. If desired, balls may be used to further reduee the friction on these rollers, as shown at 16.

Vhile the rollers 13 relieve most of the wear, I much prefer to use wearing-plates 1S between the box 4 and the rollers 13. This plate is fianged horizontally at 19, as seen in Fig. 1, and vertically, as seen at 2O in Fig. 2. The first of these flanges 19 merely keeps the plate 18 in position on the box, so that the two travel together; but the side fianges 20 absorb the wear .between the sides of the pedestals and the flanges 21 on the boxes. (See Fig. 2.)

It is believed no description of the operation of this invention is necessary, and hence it will suffice to state that as the box 4 moves up and down with respect to the pedestalstandards almost all of the wear thereon is taken by the rollers 13 and the plate 18, or either. It is obvious that either the rollers or the plate may be omitted and part of the wear still be saved; but the use of them together is preferable.

It is manifest that changes may be made without departing from the spirit of my invention, and I intend the following claims to cover all such variations and modifications as naturally come within the scope of my invention.

Vhat I claim as new is- 1. In a device of the character described, a pedestal, a journal-box, and a wearing-plate interposed between the pedestal and box and having horizontal flanges to hold the same in position and vertical flanges to take the wear oi the flanges of the said journal-box, substantially as described.

l 2. In a device of the characterdescribed, a journal-box, a pedestal-standard comprising two sides connected by a web, and an antifriction-roller supported between said web and said journal-box, substantially as described.

3. In a device of the character described, a pedestal-standard comprising two sides connected by a web having a pocket formed therein, and an antifriction-roller supported in said pocket, substantially as described.

4. In a device of the character described, a journal-box having flanges, a pedestal-standard comprising two flanged sides connected by a web, an antifriction-roller supported between said web and said box, and a wearingplate interposed between the flanges of said box and the flanges on said pedestal sides, substantially as described.

5. In a device of the character described, a

to hold the same in position and vertical.

anges to take the wear off of the flanges of said box.

6. In a device of the character described, a pedestahstandard having an integral loop for the attachment of the tie or brace rod.

'7. In adevice of the character described, pedestal having standards and integral loops on the ends of said standards, and a tie or brace rod secured in said loops.

8. A pedestal having integral pockets for antifrictiOn-rollers and loops for the attachment of the tie or brace rod.

In testimony whereof I afx my signature, in the presence of two witnesses, this 21st day of February, 1901.

PERRY BROWN.
