To all whom z'tmoy concern:

Be it'known that I, GEORGE G. FLoYn, a citizen or the. United States, residing at Granite City, in the county of Madison and.

State of Illinois, have invented certain new and useful Improvements in Car-Trucks, of which the following is a specification.

This invention relates to im roved and novel means in, railway cantruc: constructions which will permit the ready and easy removal of the bolster lengthwise through its aperture of the sideframe. litany and various schemes have been provided for reaching this desired result, but I believe that the present invention provides a construction possessing several features and characteristics of novelty and improvement. In acbolster; or, if desired, these columns may be wholly taken out of the side-frames. In

one embodiment of the invention the sides of the side-frame bordering the bolster aperture are provided with vertical under-cut grooves to accommodate correspondinglyforn'id columns, such grooves or recesses extending upwardly through the top of the side-frame to permit insertion of the columns, the latter resting on the lower ends of the grooves or recesses so as to be supported thereby.

From a consideration of the detailed description of a preferred embodiment of the invention set forth below, which should be read in connection with the accompanying drawing forming a part of this specification, it will be apparent that a car-truck including this inventionis simple in construction, economical to manufacture, and renders possible the desired results stated above.

In this drawingFigure 1 is a side elevation of a car-truck with parts omitted and the side-frame shown partially in section; Fig. 2 is a partial plan and partial horizontal section on line 2-2 of Fig. 1; Fig. 3 is a central vertical cross-section through the side-frame with the columns omitted; and Fig. 4: is a perspective view of one of the removable or shiftable columns.

By reference to the drawing it will be noted that the bolster 10 has on opposite Specification of Letters Patent.

faces of its end portion the spaced column guides 11, 11 providing between them grooves-or recesses 12 to accommodate the columns. The side-frame 13 has the usual central opening 14 for the reception of the spring-plank 15, springs 16, and the end of the bolster. In the present instance this opening or aperture is of substantially rectangular form, being bounded by the opposite side walls 17 and 18, which at their lower ends are composed of transverse flanges, their upper ends .or portions being considerably thickened as at .19 and supplied on their adjacent faces with vertical centrally-disposed undercut grooves 20 terminating at the top of the lower flange portions of such walls at 21, whereby to provide seats or supports for the vertical removable or shiftable columns or bolster guides 22 in cross-section of substantially "it-form, whereby their lateral disengagement from such grooves is prevented. The portions of such columns or guides protruding into the bolster aperture 14 of the side-frame, as will be readily understood, form the columns or guides for the bolster and are intended to fit in the above-mentioned grooves or recesses 12 of such bolster. The recesses 20 EX- tend upwardly through the top compression member 23 of the side-frame, the latter completely encircling the top ends of such removable or shiftable columns or guides because of the bosses or enlargements 24: formed on the lower part of such compression member. In order to prevent upward shifting or displacement of such columns or guides each is provided or supplied with a hole 25 extended therethrough near its upper end and adapted to receive'a pin 26 pass- -1ng thropgh holes 27 of the side-frame registering with the aperture 25. Such pins are, of course, readily and easily removable to permit the taking out or upward withdrawal of such disengageable columnsor guides. As is indicated, the aperture lei.- of the sideframe would be ordinarily constructed of substantially the same width as the over-all transverse dimension of the bolster over its column guides 11.

The removal or withdrawal of the bolster is effected in substantially the following manner: The spring lti having been taken out, the bolster may be either permitted to descend or may be maintained in the normal position shown in Fig. 1. In any case, the

shii'table columns 22, after the pins 26 have I the bolster, the parts of the side-frame con- 90 been removed, are pushed upwardly, or stituting the side-walls of said aperture bewholly removed from the side-frame if deing grooved, and columns with which the sired, so as no longer to reside in the guiding bolster column guides are adapted to cogrooves 12 of the bolster, and in such posioperate shiftably mounted in said grooves, tion of the parts the bolster is free to be there being a projection and recess connec- .1 withdrawn longitudinally laterally of the tion between each column and one of the truck through the opening 14 of the sidewalls of the groove, whereby when said colframe, as is customary in other construct-ions umns are moved out of normal position the of this general character. bolster may be taken out lengthwise through The manner in which a bolster would be the side-frame aperture, substantially as de- 40 placed in the truck and the columns brought scribed. to proper position is obvious from the above 2.
