LOG-CAR.

SPECIFICATION forming part of Letters Patent No. 423,086, dated March 11, 1890.

Application filed September 13, 1889- Serial No. 323,828. (No model.)

To all whom it may concern:

.Be it known that I, CHARLES D. SooTT, a citizen of the United States, residing at Garland, in the county of Warren and State of Pennsylvania, have invented certain new and useful Improvements in Log-Cars; and I do hereby declare the following; to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to car-trucks; audit consists in certain improvements in the construction thereof, as will be hereinafter fully set forth, and pointed out in the claims.

The principal object of the invention is to provide a log-car suitable for use on rough, uneven, and crooked roads, such as are usually built for hauling logs in lumbering districts.

My invention is illustrated in the accompanying drawings, as follows:

Figure 1 is a side elevation of a log-car having my improvements thereorn Fig. 2 is a top or plan'view of.the same. Fig. 3 is a 1011- gitudinal section through the truck-frame on the line 00 a: in Fig. 2. Fig. 4 is a like section on the line y y in Fig. 2. Fig. 5 is a transverse section on the line z z in Fig. 2. Fig. 6 is a perspective view showing a detail of construction.

Like letters refer to like parts in all the figures.

A marks the wheels; B, the axles; C, the truss frames; D, the truck bolster; E, the body-bolster; F, the reach; G, the body-bolster center plate; H, the king-bolt; J, the t ruckbolster center plate.

In cars for use on rough uneven roads it is necessary that the tru ck-frames be made so as to allow for considerable vertical flexibility, so that all the car-wheels will at all times be have no lateral play. I The vertical notches d are filled with square hollow studs 0, of castiron, through which the truss-bolts cl pass, and

thus any lateral motion is prevented, while the truss-frame is free to tilt vertically.

The body-bolster E has to be cut away, so as to receive the reach-pieces F,and to maintain the strength of the bolster E, I make the body-bolster center plate G with a strong vertical flange g at each end, which sets up into the timbers forming the bolster. This insures the stiffness of the body-bolster. The plate G, acting like the key of a straight arch, will prevent the bolster ends from sagging down when supportinglarge logs.

\Vhat I claim as new is- 1. In a log-car truck, the combination, with the truck-bolster D, which is cut away, as shown at d where it is embraced by the trussframe, of the square hollow studs 0, bolts d, and truss-frame O.

2. In a log-car, the combination, with the body-bolster E, of the center plate G, having Vertical flanges g g at its ends, which extend up into the bolster on the outside of the reachpieces F, for the purposes mentioned.

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

CHARLES D. SCOTT.
