SPECIFICATION forming part of Letters Patent No. 552,768, dated January 7, 1896.

Application iiled April 2'7, 1894. Renewed May 17, 1895. Serial No. 549,706. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOHN ALBERT MARK- LEY, a citizen of the United States, residing at Clifton Forge, in the county of Alleghany and State of Virginia, have invented certain new and useful Improvements in Pedestals for Car-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in car-trucks, but more particularly to the pedestals in which the axle-boxes work.

The primary object of the inventionV is to provide a pedestal having two limbs, one of said limbs being made removable, so as to adapt the journal-boxes and wheel and axle to be easily removed without rendering it necessary to first elevate the ear in the manner ordinarily required with cartrucks` of the usual construction.

The invention will iirst be described with reference to the accompanying drawings, which form a part of this specification, and then pointed out in the claims at the end of the description.

Referring to the drawings, Figure l represents a side view of a pedestal constructed in accordance with my invention. Fig. 2 is a similar view with one limb of the pedestal removed. Fig. 3 is a vertical sectional view on the line III III of Fig. l, looking in the direction of the arrow a. Fig. 4c is an inside view of the detached limb 5 and Fig. 5 is a detail sectional view, the section being taken on the line V V of Fig. l, looking downward.

The main portion of the pedestal A may be formed integrally with a cross-piece or yoke extending to land integral with a corresponding portion of an adjacent pedestal, or it may be formed separately therefrom for independent attachment to the truck-frame, but the two parts are preferably formed from a single piece of steel.

The present invention resides mainly in the removable limb, and in other respects the pedestal does not difter essentially from pedestals in common use, and the journal-boxes and other parts of the truck an d bearings may be assembled andsecured together in the usual or any proper manner.

It has heretofore been necessary, in order to remove the journal-boxes for substitution or repairs or for the purpose of removing and replacing the axle and wheels, to elevate the car with its contents when loaded until the lower ends of the limbs of the pedestal are raised above the plane of the axle in its normal position with the car resting thereon,

thus involving considerable work, great waste" of time and unnecessary expense. To save the time, labor and expense thus necessarily consumed with present constructions, l propose to provide a pedestal with a removable limb, which may be readily detached b y simply lifting the car suiliciently to relieve the weight upon said limb, whereupon the latter may be removed, so as to permit access to the j ournal-boXes or the ready removal of the axle and wheels. To this end one of the limbs of the usual U-shaped construction in crosssection is formed in two sections A A2 and provided with a corresponding sectional me tallic bar or iilling A3, the sections of which are detachably connected together, the upper section a' of the lling being secured to the rigid upper portion A of the removable limb of the pedestal and the lower section a2 to the removable portion A2 of said limb. The upper and lower sections of the limb are preferably united by a scarf or rabbet joint, which may be formed by rabbeting the adjacent ends of the filling and inserting through the overlapped tongues thus formed thereon a removable bolt or key B, one of said tongues projecting into a recess formed between the same and the adjacent inner wall of the limb section A. The said key or bolt B is preferably made square in cross section and adapted to iit a correspondingly-shaped opening formed between the adjacent ends of the two sections of the limb by recessing said ends. The two sections of the limb are further secured by means of a key C, which is fitted in apertured lugs c c', projecting from the sides of the parts A A2, respectively, of said removable limb. D may denote a tie or brace extending between the two pedestals. By these means the removable portion of the pedestal is firmlysecured in place and braced against vertical and lateral movement, and at the same time is rendered easily removable for the purpose of permitting the journal-boxes to be removed and other boxes substituted therefor or to permit the ready removal of the axle and wheels without rendering it necessary to elevate the car in the manner required with pedestals oi' the character now in common use.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of thc United States, is-

l. In a car truck, a pedestal having two limbs one of said limbs comprising an upper and a lower section, the latter being rcmovably secured to the former, substantially as and for the purpose set forth.

2. A U-shaped pedestal having one limb thereof rigid and the other removable, the latter being secured to thc former so as to form a rigid connection therewith, but capable of being readily removed so as to permit easy access to or removal of the journal-boxes and wheel and axle, without elevating the car, substantially as described.

3. In a car-truck, a pair of pedestals each provided with a detachable limb, and having their main portions formed integrally with a .connecting frame-bar, and means for rigidly but removably securing said limbs to said main portions, substantially as described.

4. A pedestal having a rigid and a removable limb, the latter consisting of a rigid and a removable section, the adjacent ends of the two sections being recessed so as to form a square or polygonal opening between them, a filling-piece in two sections secured to said rigid and removable limb sections, having rabbeted ends or tongues adapted to overlap each other and provided with an opening therethrough which registers with the opening between the limb sections, and a bolt or key fitting said openings so as to bind said parts together, substantially as described.

5. A pedestal having a rigid and a removable limb, the latter consisting of a rigid and a removable section, the adjacent ends of the two sections being recessed so as to form a square or polygonal opening between them, a filling-piecc in two sections secured to said rigid and removable limb sections, having rabbeted ends or tongues adapted to overlap each other and provided with an opening therethrough which registers with the openings between the limb sections, a transverse bolt or key fitting said openings and a vcrtically disposed key fitting eye-pieces projecting from the sectional limb, whereby the parts are firmly bound together vand braced against vertical and lateral movement, substantially as described.

In testimony whereof l affix. my signature in presence of two witnesses.

JOHN ALBERT MARKLEY.
