To ctZZ whom it ntay concern.-

Be it known that I, BRODERICK HASKELL, of Saginaw, in the county of Saginaw and State of Michigan, have invented a certain new and useful Improvement in Car-Trucks, of which improvement the following is a specification.

The object of my invention is to provide a car-truck of the arch-bar or diamond type which shall be of simple, strong, and inexpensive construction and in which a firm connection of the arch-bars and inverted archbars may be effected without involving the employment of the separate columns or bolster-guides and long column-bolts which have heretofore formed essential parts of trucks of this class.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view, in elevation, of a car or tender truck, illustrating an embodiment of my invention; Fig. 2, a plan or top view of the same; Fig. 8, a side view, inelevation and on an enlarged scale, of one of the side frames; and Figs. 4. and 5, transverse sections on the lines a a and b b, respectively, of Fig. 3.

In the practice of my invention I provide a truck-frame having each of its side-frame members composed of an arch-bar 1 and an inverted arch-bar 1", each of which is an integral casting, preferably of steel. The relation and inclination of the horizontal and inclined portions of the bars 1 and 1 are substantially the same as in trucks of the Master Gar-Builders type, and they are made of such transverse section as will combine strength and lightness, being in the instance shown of T-section, although any other suitable and preferred form may be adopted.

A downwardly-depending bolster-guide 1 is cast integral with each of the arch-bars 1, at each end of the central horizontal portion thereof,and corresponding upwardly-projecting bolster-guides 1 are cast upon the ends of the central horizontal portion of each of the inverted arch-bars 1. The inner faces of the bolster-guides stand at a proper distance apart to admit the bolster 5, which is supported by springs 6 upon a spring-plank 7 in the ordinary manner, and the faces are flat in order to properly guide the bolster in bolts 3, provided with nuts which may be brought to a proper tight bearing, and the solidity of the connection maybe secured by keys, nut-locks, split pins, or other suitable known means.

The outer ends of the arch-bars and inverted arch-bars abut and are socketed to receive journal-box bolts 30, by which the bars are connected one to the other and to the journalboxes 2, which are provided with proper journal-bearings for the axles 8, on which the wheels 9 of the truck are secured. The journal-box bolts pass through the pedestal tiebars 4, which connect the two journal-boxes of each of the side frames and are fitted with nuts which bear on the lower sides of the podestal tie-bars. The pedestal tie-bars may be either of cast metal of desired cross-section or of wrought metal, as preferred.

The bolsterguides 1 are filleted at and near their junction with the main bodies of the bars of which they form part in order. to afiord proper strength, and they afford facilities for the attachment of transoms of any preferred form by which the opposite side frames of the truck may be connected in the ordinary manner. It will be seen that under the construction above described the long and heavy column-bolts which are required for the connection ofthe independent columns or bolster-guide plates ordinarily employed are'dispensed with.

Iclaim as my invention and desire to secure by Letters Patent 1. In a car-truck, the combination of an arch-bar having a pair of integral bolsterguides depending from its middle portion, an inverted arch-bar having a pair of integral bolster-guides extending upwardly from its middle portion and adapted to abut against the bolster-guides of the arch-bar, and connections securing the abutting bolster-guides one to the other.
