SPECIFICATION forming part of Letters Patent No. 684,817, dated October 22, 1901.

Application filed August 10,1901- Serial No. 71,621. (No model.)

To all whom, it may 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 Oar-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. 3, a vertical transverse central section; and Figs. 4 and 5 transverse sections, on an enlarged scale, through one of the side frames on the lines a a and b 6, respectively, of Fig. 1.

In the practice of my invention I provide a truck-frame having each of its side frame members composed of on arch-bar 1 and an inverted arch-bar 1, each of which is formed of sheet or plate metal bent or pressed into U or channel section. The relation and inclination of the horizontal and inclined portions of the

bars

1 and 1 are substantially the same as in the trucks of the Master Oar- Builders type, and their flanges or vertical members are turned in opposite directions, those of the archbar 1 extending downwardly and those of the inverted arch-bar 1 extending upwardly. One of said bars, in this instance the inverted arch-bar 1*, is made wider at its ends than the other, so that the horizontal end portions of thelatter fit within the corresponding portions of the former, as shown in Figs. 1 and 5.

A downwardly-dependin g bolster-guide 1 is formed integral with each of the arch-bars l, at each end of the central horizontal portion thereof, and corresponding upwardly-projecting bolster-guides 1 are formed upon proper distance apart to admit the bolster 5,

which is supported by springs 6 upon a spring-plank 7 in the ordinary manner, and said inner faces are flat in order to properly guide the bolster in its vertical movements. The adjoining ends of the bolster-guides of the arch-bars and inverted arch-bars are preferably adapted to abut, and filling-blocks 1 are fitted in the space between the side flanges of the bolster-guides, said blocks serving to stifien and strengthen the frames at these points and to serve as distancepieces for connecting bolts or rivets 3, which pass through the side flanges and fillingblocks and firmly secure the arch-bars and inverted arch-bars together. When bolts are employed, they are provided with nuts, which may be brought to a proper tight bearing, and the solidity of the connection may be insured by keys, nut-locks, split pins, or other suitable known means. If desired, the ends of the upper and lower bolster-guides may be separated sufficiently far to allow lateral projections or shoulders on the filling-pieces to be interposed between them, in which case they may abut against said interposed projections.

As before mentioned, the horizontal end portions of the arch-bars and inverted archbars overlap or are fitted one within another, and filling-blocks 1 are inserted in the spaces within said horizontal end portions. The arch-bars and inverted arch-bars are connected at these portions of their length one to the other and to the journal-boxes 2 by journal-box bolts 80, which pass through sockets in the arch-bars, inverted arch-bars, filling -blocks, journal-boxes, and pedestal tie-bars 4 and are fitted with nuts which bear 'on the lower sides of the pedestal tie-bars.

The journal-boxes are provided with proper journal-bearings for the axles 8, on which the wheels 9 of the truck are secured.

The bolster guides 1 afford facilities for the attachment of transoms of any of the various known forms by which the opposite side frames of the truck may be connected in the ordinary manner, or, if preferred, these transverse connecting members may be attached to the bodies of the arch-bars and inverted arch-bars. construction above described the long and heavy column-bolts which are required for the connectionof the independent columns oribolster guide-plates ordinarily employed are dispensed with. 1

, I claim as my invention and desire tosecure by Letters Patent X 1. In a car-truck, the combination of an arch-bar of U or channel section, having a pair of integral bolster guides depending from its middle portion, an inverted arch-bar, of similar section, having a pair of integral bolster-guides extending upwardly from its middle portion, filling-blocks fitting within the bolster-guides, and connections securing the adjoining bolster-guides one to the other and to a filling-block.

2. In a car-truck, the combination of an arch-bar of U or channel section, an inverted arch-bar of similar section, said bars overlapping or fitting one within the other at their horizontal end portions, filling-blocks fitting Within the horizontal end portions of said bars, and connections securing said bars one to the other and to the filling-blocks.

8. In a car-truck, the combination of an arch-bar of U or channel section, having a It will be seen that under the' pair of integral bolster guides depending from its middle portion, an inverted arch-bar, of similar section, having a pair of integral bolster-guides extending upwardly from its middle portion, filling-blocks fitting within the bolster-guides, connections securing the adjoining bolster-guides one to the other and to a filling-block, filling-blocks fitting within the horizontal end portions of the arch-bars and inverted arch bars, and connections se; curing said bars one to the other and to said filling-blocks. I a p 4. In a car-truck, a side frame comprising a bent or pressed met-a1 arch-bar, of U or channel section, and a bent or pressed metal inverted arch-bar, of similar section, said bars being connected at their end portions through their main bodies, and connected, intermediate] y of their ends, through bolsterguides integral therewith.

5. About or pressed metal arch-bar for the side frame of a car-truck, which is of U or channel section and is provided with a pair of bolster-guides integral therewith, extending from its middle portion.
