To all whom it may concern: terposed between the two members at their Be it known that I, GEORGE W. SCOTT, of points of junction.

(Shown in detail in Figs. 9 and 10 of This invention relates to car-trucks, being the drawings.)

This upper crossor tension member is inclined upward from tie not only serves to connect the diamond the center toward each end to meet the upframes and, in conjunction with the lower 50 per member, and spacing-blocks 19 are incross-tie, firmly binds the truck together and preserves the fixity and relative position of the column-guides, but it also serves as a means for the attachment of the brake-rigging in the case Where the truck is provided with inside brakes, as in the construction shown. In this construction I employ a guide or support for the dead-lever 40, consisting of a bar 41, bent to form a loop to receive the end of the lever and having one arm of theloop extended across and secured to the two members 39 of the upper cross-tie, while the other arm is bent at right angles and secured to the ver tical'face of one of said members. This construction serves not only to provide a firm attachment for the dead-lever, but also to securely cross-brace the upper cross-tie. The live-lever guide 41 is secured to the vertical face of the other member 39 of the upper cross-tie, the ends of the guide being bent up at right angles to the body for this purpose, as shown in Fig. 2 of the drawings. The brackets 42, from which the brake-beams are suspended, are also secured to the transverse members 39 of the upper cross'tie 39, so that the entire brake-rigging is suspended from this upper cross-tie.

The center plate 43, as shown in detail in Fig. 14, is riveted or bolted directly to the upper member 15 of the truck-bolster, the rivets passing directly through the bearing surface of the plate instead of through outlying flanges, as in the usual construction, and the countersunk rivets or bolt-holes 4.4 serve as convenient reservoirs for the lubricant.

It will be noted that the combined columnguide and spring-seat furnishes a strong and simple structure well adapted for its purposes, the lateral flanges serving to firmly hold the arch-bars and relieve the columnbolts from side strains. The construction of the spring-cap and the mode of securing it to the end of the bolster is also particularly advantageous, and the mode of cross-tying the diamond frame serves to maintain the proper relative position of the column-guides, and thus insure freedom of motion for the springcaps and bolster. The mode of supporting the brake-rigging not only serves to strengthen the truck-frame, but also insures the maintaining of the proper relative position between the brakes and the wheels.

I claim-- 1. In a car-truck, the combination, with spring-caps, of a bolster comprising a compression member, and a tension member ex tending between the compression member and spring-caps, supporting the former vertically upon the latter, and provided at its ends with upward projections which abut against the ends of the compression member and with downward projections which abut against the outer faces of the caps, substantially as described.

2. In a car-truck, the combination, with spring-caps, of a bolster comprising a compression member and a tension member separated at their centers and converging at their ends, the tension member being secured at its ends between the caps and compression member, filling-blocks located in the meeting angles of the two bolster members, side bearings located on the bolster above the caps, and securing-bolts passing vertically through said several parts whereby they are secured together, substantially as described.

3. In a car-truck, the combination,with the diamond frames forming the sides of the truck-frame, of upper and lower cross-ties connecting said diamond frames and secured thereto by means of the column-bolts, substantially as described.

4. In a car-truck, the combination,with the diamond frames, of a cross-tie comprising a channel-shaped body and terminal plate-gussets, whereby its ends are adapted to be sesured by means of the column-bolts, substantially as described.

5. In a car-truck, the .combination,with the diamond frames, of an upper cross-tie comprising two parallel angle-pieces and connecting-plate cross-pieces at their ends, whereby said tie is adapted to be secured by means of the column-bolts, substantially as described.

6. In a car-truck, the combination,with the diamond frames, of a lower cross-tie comprising a channel shaped body and terminal plate-gussets, and an upper cross-tie comprising two parallel anglepieces and connecting-plate cross-pieces at their ends, whereby said ties are adapted to be secured by means of the column bolts, substantially as described.

7. In a car-truck, the combination,with the diamond frames, of an upper cross-tie comprising parallel angle members connected at their ends to each other and to the columnbolts, a dead-lever guide or support having one arm extended across and secured to the top flanges of the two parallel members, and the live-lever guide and brake-beam-supporting brackets also secured to said angle Inembers, substantially as described.

8. In a car-truck, a lubricated center-bearing, comprising, in combination, a truck-bolster, a center plate having a bearing-surface cup-shaped in form and adapted to receive a correspondiugly-shaped projecting bearingplate on the body-bolster, vertical apertures through said center plate having enlarged recesses at their upper ends formed in said bearing-surface, and rivets securing said center plate to the bolster and countersunk in said recesses, whereby reservoirs for the lubricant are formed, substantially as described.
