SPECIFICATION forming part of Letters Patent N 0. 745,119, dated November 24, 1903.

Application filed May 1903. Serial No. 157,208. (No model.)

To all whom/it may concern.-

Be it known that 1, WILLIAM B. SCAIFE, of Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Oar-Truck, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a side elevation of the blank for the side frame, showing in dotted lines the contour after pressing. Fig. 2 is a top plan View of the pressed side frame. Fig. 3 is an inner side elevation of the pressed frame. Fig. 4 is a bottom plan view of the frame. Fig. 5 is a side elevation, partly broken away, of the completed side frame. Fig. 6 is a transverse vertical section,theleft half being taken through a pedestal and the right half through the transom; and Fig.7 is a top plan view of the truck-frame with the left-hand half in horizontal section.

My invention relates to the class of pedestal car-trucks, and is designed to provide a truck-frame composed partly of pressed-steel shapes and partly of rolled shapes, such as angles, which shall be of great strength and may be readily and rapidly made. It is also designed to provide a side frame which shall have great stiffness against lateral bending strains.

In the drawings, Fig. 1 shows the blank from which the body of the side frame is pressed up. This blank 2 is provided with vertically-extending slots 3 3 near each end, the upper corner 4 being rounded off. This blank is heated and placed in a press, in which it is shaped into the side frame body mem ber (shown in Figs. 2, 3, and 4) by bending the blank on the dotted lines of Fig. 1. The upper portion of the blank is bent into a wide top flange 5, which gradually tapers in width through the portions 6 to the narrower portions 7 7 of the pedestal. The lower part of the blank is bent into a narrower flange 8, the end portions of which taper toward the plane of the blank, as shown in Fig. 4. The body 2 is narrowest at the central portion, its end portion gradually enlargingthrough the parts 9 9 to the pedestals. The flanges 7 are continued at 7' down along the outer leg of each pedestal, and the pedestal-opening is also provided with side flanges 10 and 11,which.

are joined together at the top by the flange 12. By reference to Fig. 4 it will be seen that all of the flanges prod need by pressing upthe blank extend inwardly and in the same direction at right angles to the plane of the blank-body. After the blank is thus pressed up an angle is riveted along its outer face, this angle extending from one pedestal to the other and forming tension members in its intermediate portions. The outer portion 13 of this angle extends along the outer leg of the pedestal, thence over the top of the pedestal at 14, and thence downwardly and inwardly to the portion 15 to the point a, where the flange 8 of the pressed blank begins to converge toward the pedestal. The angle is continued through the horizontal portion 16to the similar point a on the other side of the transom and thence through the successive portions 15, 14, and 13. The flange 17 of this angle projects outwardly in the opposite direction to the pressed flanges of the side frame. The two flanges 17 and 10 combine to form a broad flat face along the outside of the pedestal-opening, and on these flanges is mounted the Wearing-plate 18. To support the inner wearing-plate 19, I rivet a vertical angle 20 along the inner side of the pedestal-opening, this merely extending up to the inclined portion ]5 of the continuous angle. The pedestal tie bars are shown at 21. The inclined portions 15 of the continuous angle extend from the top of the pedestal downwardly and inwardly to the lower edge of the transoms, substantially in line with the strains coming to the transom and passing to the pedestals. There is therefore no bending movement upon these inclined portions, which form true tension members.

The'transom isshown as composed of two pressed channels 22, placed in parallelism, with their flanges 23 and 24 extending outwardly. The end of each channel is secured to the side-frameweb by a pair of angles 25, as shown in Fig. 7, and the securing-rivets for these angles extend through a strengthening-plate 26, covering the inner face of the web of the side frame in the central portion. This strengthening shape is preferably rectangular in shape, as indicated in Figs. 5 and 7. The wide. top flange 5 ofl'fthe side frame lies on the top flanges 27 of the.\trans om-channel and is riveted thereto. The lower flanges 24 are correspondingly riveted to the flange 8 of the side frame.

It will be noted that the pressed flanges 7 are of considerable depth and stiffen the ends of the pedestals laterally. The flanges projecting in opposite directions from the vertical plane of the web-on the inner side of the pressed-up flanges andon the outer side the an gle-flan gesgive great stiffness against lateral strain.

The advantages of my invention result from the combining of the pressed flanged blank with the flanged shape which is secured thereto. Great stiffness is afforded, the construction is simple and easily made, and the advantages of structural shapes and pressed shapes are combined.

Many variations may be made in the form of the pressed blank, the rolled shape riveted thereto, the arrangement of the pedestals and Wear-plates, &c., Without departing from my invention.

I claim- 1. A truck side frame having a pressedplate body with pedestal-openings, and an outer flange extending alongside said openings, and a longitudinally-extending flanged shape riveted to the Web of the pressed body, with its flange projecting in the opposite di rection to that of the body-flange; substantially as described.

2. A truck side frame having a pressedplate body withsubstantiallycontinuous edge flanges projecting laterally, and a longitudinal flanged shape riveted to the body with its flange projecting in the opposite direction to that of the pressed flanges; substantially as described.

3. A truck side frame consisting ofa pressedsteel body with edge flanges and a continuous flanged shape riveted to the vertical web of the body and havinginclined portions extending from the tops of the pedestals downwardly toward the lower part of the transom; substantially as described.

4:. A truck side frame havinga pressed-steel body with an inwardly-projecting fiangesurrounding the pedestal-opening, a longitudinal flanged shape having its end portion extending down the outer pedestal leg, the flange of said shape projecting in the opposite direction from the pressed flange on the body; substantially as described.

5. A truck side frame comprising a pressedsteel body with inwardly-projecting flanges surrounding the pedestal-opening, a continuous longitudinal angle having the flanges of its end portions projecting outwardly along the outer leg of the pedestal, and short vertical angles secured along the inner face of the pedestal-opening with their flanges projecting outwardly; substantially as described.

6. A truck side frame having a body composed of a pressed-steel blank with substantially continuous edge flanges extending around its margin and around the pedestalopenings; and a flanged shape riveted to the body with its flange projecting in the opposite direction to that of the pressed flanges; substantially as described.

'7. A truck having a pressed steel side frame, a strengthening-plate in its central portion, and a transom having its members secured to the side frame by pairs of angles, the securing-rivets extending through the strengthening-plate; substantially as described.

8. A pressed steel side frame having pressed flanges, and a continuous angle extending over both pedestals and thence downwardly and inwardly to and along the under part of the transom-juncture; substantially as described.

9. A truck side frame having a pressedplale body with edge flanges projecting laterally in the same direction, and a longitudinally-extending flanged shape riveted to the web of the pressed body with its flange projecting in the opposite direction to that of the bOdyfl-anges; substantially as described.

In testimony whereof I have hereunto set my hand.

WM. 13. SOAIFE.
