ROBERT EDWIN POWERS, OF J OHNSTOWN, PENNSYLVANIA.

CAR--TRUCK.

SPECIFICATION forming part of Letters Patent No. 715,601, dated December 9, 1902.

' Application filed July 5, 1902. Serial No. 114,501. (No model.)

To all whom it may concern:

Be it known that I, ROBERT EDWIN Pow- ERS, a citizen ofthe United States, residing at Johnstown, in the county of Oambria and State of Pennsylvania, have made certain new and useful Improvements in Oar-Trucks, of which the following is a specification.

My invention is an improvement in truckframes for railroad-cars; and it consists of certain novel constructions and combinations of parts, as will be hereinafter described and claimed. In the drawings, Figure 1 is a sectional top plan view, partly broken away, of a truck embodying my invention. Fig. 2 is an elevation, partly in section, of my improved truck-frame. Fig. 3 is a side view, and Fig. 4 an end view, of the beam from which the side plates of the truck are made, the outline of the side-plate blank being indicated in dotted lines in Fig. 3. Fig. 5 is a detail perspective view showing the side-plate blank ready for the bracing devices. Fig. 6 is a detail perspective View showing the upper edge binder for the side plate and the crossbeam and gusset-plate applied thereto. Fig. 7 is a detail perspective view showing the brackets riveted to the cross-beam for the purpose of carrying the brake-beam hanger. Figs. 8 and 9 illustrate somewhat different constructions within the broad principles of the invention. Figs. 10 and 11 ill ustrate the bracing-yoke and a guide-yoke for supporting the car-axle boxes. Fig. 12 illustrates in detail the bracing devices at the lower end of the box-guide, and Fig. 13 shows in detail one of the knee-brackets.

By my invention I provide the side plates of the truck with the central depressions between their ends and reinforce the upper depressed edge of the said plates by means of binder-strips of angle metal, such as shown in Fig. 6.

In carrying out my invention it is preferred to form the blank A for the side plate of the truck-frame from an I-beam B, such as shown in Figs. 3 and 4. This I-beam, it will be noticed, is flanged at both edges, and in cutting it to produce the blank or form shown in .ter-pin support G.

Fig. 5 the beam B is cut on substantially the dotted lines of Fig. 3, which will result in producing the form of blank shown in Fig. 5. In this construction the upper flange of the I-beam has been cut away. To compensate for this loss of strength and to also provide sufficient strength in the upper centrally-depressed edge of the blank A, I provide a binder-strip O, of. angle metal, such as shown in Fig. 6, and rivet the same securely to the upper depressed edge of the blank A, as shown in Fig. 2, thus reinforcing the upper edge of the side plate of the truck-frame and affording midway between the ends of such side plates depressed seats for the gussetplates D, which are riveted to the horizontal flange of the binding-strip C, while the vertical flange of said binding-strip is riveted t0 the body A of the side plate, as will be understood from Figs. 2 and 5, it being noticed from Figs. 5 and 6 that the binding-strip C coincides With the contour of the upper edge of the body or blank A of the side plate. The cross or channel beams E are secured to the gusset-plates at the opposite sides of the truck-frames, and tothese channel-plates are secured the lugs or brackets F for the purpose of carrying the brake-beam hangers. The cross-beams E operate to carry the cen- (See Fig. 1.)

In producing the blankor body A (shown in Fig. 5) it will be noticed the lower flange of the I-beam is left intact at a between the openings H, formed from the lower edge of the body A, near the opposite ends thereof, and flange-sections h are left intact at the lower ends of the wings H, forming the outer Walls of the said openings H. These openings H are for the car-axle boxes I, (see Fig.

1,) whichboxes I are channeled vertically at I in their. opposite edges and slide in the guide-plates presently described. To reinforce the bod y-plates A, surrounding the openings H, and to also better support the guideplates for the car-axle boxes, I provide the angle-yokes J, having wings J, riveted to the body-plate or web A along the sides and crown of the opening H, and right-angle wings J against which is fitted the yoke-shape guide plate K, which is U shape in cross-section and is fitted within the opening H upon the brace-yokes J, and is bolted thereto at L by the bolt M, which carries the spacing devices N, which bridge the lower end of the opening H, as shown in Fig. 2. As shown in Fig. 12, the bracing devicesN include a plate N, having depending side flanges N and end flanges N the latter being perforated for the bolt N and spaced apart by the space-tube N fitted on the said bolt between the end flanges N Angle-brackets 0 may be provided, as shown in Fig. 2, to brace the lower edge of the guide-yoke and angle-brace where the same project below the lower edge of the body-plate A. The angle brackets or knees 0 may, if desired, be constructed as shown in Fig. 13, in which the base-flanges P of the web P are bolted to the crown-plate R of a forging, which is provided with a depending wing R secured by the bolt N and a cross-plate S of a forging S is also secured by said bolt N' and has side wings S riveted at 8 in connection with the side plates of the forging R, as will be understood from Fig. 13.

While it is preferred to form the bodyplates or blanks A by shearing the same from the I-beam, as illustrated in Figs. 3 and 4, it may be desired in some instances to form the side plate from a flat plate or web P, reinforced at its upper and lower edges by the angle-strips P and P, as shown in Fig. 8, or from an L-shape body Q, having a base-flange Q and reinforced at its upper edge by the angle binding-strip Q as shown in Fig. 9, and it will be understood that in these constructions shown in Figs. 8 and 9 the upper edge of the body-plate or web may have a contour similar to that shown in Figs. 2 and 5 and before described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A side frame for car-trucks, comprising a body-plate or blank, having its upper edge depressed between its ends and provided near its opposite ends with openings leading from its lower edge, the angle binding-strip conforming to the upper depressed edge of the body or blank, and secured to the latter, the bracing frames or yokes secured to the body or blank surrounding the openings formed from the lower edges thereof, the guide-yokes fitting and held to said brace-yokes and forming guides for the car-axle boxes, devices bridging the lower ends of the said openings, the gusset-plates secured to the depressed portions of the binding-strips for the upper edges of the body plates, and the crossbeams secured to the gusset-plates, substantially as set forth.

2. A side frame for car-trucks, comprising the body-plate or blank, having its upper edge cut away forming a recess between its ends and provided in its lower edge near its opposite ends with openings for the car-axle boxes, and the reinforcing-strip of angle metal applied to the depressed edge of the body-plate and secured, substantially as set forth.
