IO to make and use the same.

My present invention relates to car-trucks, and has for its object to improve the same in point of simplicity, durability, and cost.

The invention consists of the novel devices 5 and combinations of devices hereinafter described, and defined in the claims.

In the accompanying drawings, which illustrate my invention, like characters indicate like parts throughout the several views.

2 Figure 1 is a view in side elevation, with some parts broken away, showing a car-truck designed in accordance with my invention. Fig. 2 is a transverse vertical section taken approximately on the irregular line 1.9.1. 131

2 Fig. 1, some parts being broken away. Fig. 3 is a transverse verticalsection, on the line a) m of Fig. 1, some parts being broken away; and Fig. 4 is a plan view showing in detail a portion of one of the trussed side frames of 3 the truck.

The nnmeralsl, 2., and 3 indicate, respcctively, the top arch-bar, the lower arch-bar, and the bottom bar of one of the trussed side frames 01 the truck. The ends of these bars are not shown in the accompanying drawings; but they may be secured to the journal-boxes in the usual or any suitable Way. One of the arch-bars is bent to form bolster-columns. In the preferred arrangement the top arch-bar 1 4 atv its intermediate or central portion is depressed or bent down to form vertical sections 4., and a depressed horizontal portion 5, which portions 4; and 5 form a Ushaped stirrup. The vertical bar portions 4. afford bolster-col means, and the depressed horizontal bar portion 5 rests upon the trussbar 2 and is bolted thereto, as presently described. A saddleplate 6 is seated upon the horizontal bar portion 5, and a pair of transoms or angle steel 5 t1e-bars 7 are rested at their ends upon the saddle-plate at the opposite sides of the truck and are riveted thereto, as shown at 8, and are riveted to the vertical column-Ferming portions i at 9. N nttcd bolts 10 are passed vertically through the horizontal flanges oi the tie-bars 7, through the saddleq'ilate b, through the horizontal lmr-plato 5, and through the bars 2. and 3, rigidly tying the said parts to gether. The gap left between the upper ends of the colmnn-lmming portions -l is spanned by a bridge-bar 1 1, which is preferably in the form of a malleable casting, and has flanged ends that overlap the body portions of the top arch-barl and closely lit the angle portions at the junctions of the upper ends of said 001- 5 uinns with the body of said arch-bar 1. "To further reinforce and stiffen the bent portions of the bar 1 at the upper ends oi the column- "forming portions I, flanged corner-angles 12 are placed in the angles thereof, as best shown 7 O in Figs. 1 and Nutted bolts 13 are passed through the ends of the lin-idge-bar 11 and through the bar .1 and through the outwardL turned ends of the angle-brackets .12 to rigidly tie the said parts togetl'ier. Also, as shown, the vertical flanges of the raid anglebrackets 12 are riveted to the upper portions of the column-forming portions 4, as indicated at 1 1. Theangle-brackets IZare formed withinwardly-projected arms 15, which ai'lord supports to which the l)rakediangers may be attached. (See particularly Fig-.fl.)

That construction above described, while very strong and durable, is cheap to build. An arch-bar in a trussed car-lrznne having 5 bolster-colulnns integrally formed therewith, but separate from the other archdmrs, 1 consider a broadly new Feature and desire to claim the same as such. llence it will of course be understood that the said arch-bar 9 and bolster-columns may be integrally cast or otherwise formed and may be formed with flanges or ribs, if desired. However, further novelty is involved in the construction illus trated in the'drawings, wherein the top archbar at its intermediate portion is bent downward in the form of a stirrup or yoke, the vertical sections of which allord bolster-coluinns, and in the combination therewith of a detachable bridge-bar rigidly connected to I00 the upper ends of the column-forming sections of the bar and spanning the space between the same. The said bridge-bar should of course be detachable in order to facilitate the application and removal of the truck-bolster and lateral-motion devices and springs, which parts may be of any suitable construction. The lateral-motion device illustrated in this application involves novel features of construction, which are not, however, herein claimed, since the same are set forth and claimed in my pending application, Serial No. 227,094, filed of date October 4, 1904, entitled Lateral-motion device for car-trucks.

The numeral 16 indicates the truck-bolster, which, as shown, is provided at its ends with depending chafing-plates 17, that work against the inner surfaces of the column-forming bar portions 4 and are provided on their inner faces with vertical guide-ribs 18.

A lower roller-bearing 19 is seated on the saddle-plate 6 and is held against sliding movements transversely of the truck by flanges 20 on said plate, which engage with end flanges of the said bearing. This roller-bearing 19 is formed with roller-seats 21, in which rest bearingrollers 22.

The upper roller-bearing 23, which in the construction illustrated serves as a combined roller-cap and spring-base, is formed with roller-seats 24, which bear upon the upper portions of the rollers. As shown, these rollerseats 21 and 24 are formed with flat bearingsurfaces that diverge from horizontal planes, as more fully set forth and claimed in my copending application above identified. Also, as shown, the lower bearing 19 has an integrally-cast stop-lug 25 at its inner extremity with which the upper bearing 23 engages under its inward movement to limit the endwise movement of the bolster transversely of the truck. Said upper bearing 23 at its sides is, as shown, provided with upturned guide-lugs 26, that are grooved, so that they can slide vertically on the ribs 18 of thebolsterchafing-plate 17. By this means the upper roller-bearing 23 is caused to travel with the bolster transversely of the truck.

Springs 27, as shown four in number, are interposed between the bearing or combined rollercap and spring-base 23 and the overlying end of the bolster, and, as shown and preferred, a shimming-block 28 is interposed between the upper ends of said springs and the horizontal overlying web at the end of said bolster.

From what has been said it will be understood that my present invention, as herein claimed, relates to the construction of the truck-frame and not to the form of lateralmotion device nor to the bolster.

hat I claim, and desire to secure by Letters Patent of the United States, is as follows:

1. A trussed side frame for car-trucks provided with an arch-bar constructed to afford l a combined arch-bar and bolster-columns, formed integral with each other and rigidly connected to the other arch-bar, substantially as described.

2. In the trussed side frame of a car-truck, an arch -bar bent to form bolstercolumns which are integral therewith and rigidly connected to the other arch-bar, and a detachable bridge-bar rigidly connecting the angles of the bent arch-bar and columns, substantially as described.

3. In the trussed side frame of a car-truck, a top'arch-bar having formed integrally with its intermediate portion a depending stirrup, which is rigidly connected to the lower archbar of said frame, and the sides of which afford bolster-columns, substantially as described.

4:. In the trussed side frame of a car-truck, atop arch-bar having integrally formed therewith, at its intermediate portion, adepending stirrup that is rigidly connected to the lower arch bars of said frame, and the sides of which afford bolster-columns, and a detachable bridge-bar, rigidly secured to the angular portions of said top arch-bar and stirrup, and spanning the gap between the upper portions of said columns, substantially as described.

5. In the trussed side frame of a car-truck, the combination with the lower arch-bar thereof, of a top arch-bar 1, bent downward at its intermediate portion to form a stirrup 4 5, the

sides 4 of which afford bolster-columns, and

a bridge-bar ll detachably secured to the upper portions of column-forming sections A, and spanning the gap in said bar 1 between said columns, substantially as described.

v 6. In a trussed side frame of a car-truck, the combination with a top arch-bar having bolster-columns integrally formed therewith, and rigidly united to the lower bars of said frame, a bridge-bar detachably united to the upper portions of said columns, angle-brackets 12 rigidly secured to the upper ends of said columns and to said top arch-bar, and provided with an inwardly-projecting arm 15, affording a bearing for a brake-hanger, substantially as described.

7. A trussed side frame for car-trucks provided with an arch-bar constructed to afford a combined arch-bar and bolster-columns, and rigidly connected to the other arch-bar, substantially as described.

8. In a trussed side frame of a car-truck, an arch-bar constructed to afford a combined arch-bar and bolster-eolumns,and a detachable bridge-bar rigidly connecting angles of the arch-bar and columns, substantially as described.

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