SPENCER OTIS, OF CHICAGO, ILLINOIS.

TIE-BAR FOR CARTRUCKS.

SPECIFICATION forming part of Letters Patent N0. 694,492, dated March 4, 1902.

Application led October 30,1901. Serial No. 80,533. (No model.)

To ali whom 'it may concern:

Be it known that I, SPENCER OTIS, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improve ments in Tie-Bars for Car-Trucks, of which the followingis a specication, reference being had therein to the accompanying drawings.

This invention relates to the diagonal tiebar or tie-bars used between the two side frames of a car-truck, particularly a car-truck used with freight-cars; and the objects of my invention are to obtain not only a tie-bar having forked ends without a weld or a bolt to tie the parts in the center, but to obtain a tiebar of that class provided with tapering flanged sides to give vertical rigidity to the tie-bar, which will react against the jar and vibrations to which the tie-bar is subjected along the center of its length without materially adding to the cost of the tie-bar. I attain these objects by the construction illustrated in the accompanying drawings, in which- Figure 1 is a top View of a plate of the desired length and width of, for example, eight inches, showing by dotted lines thereon where it is intended to flange down the edges to render it of channel shape. Fig. 2 is a bottom View of the tie-bar made from the plate shown in Fig. l. Fig. 3 is a side view of the tie-bar. Fig. 4 is a transverse vertical section ofthe same on line :n w of Figs. l and 2. Fig. 5 is a similar section on line y y of Figs. 1 and 2. Fig. 6 is a similar section on line .e z of Figs. l and 2.

To produce the tie-bar of the form desired according to my invention, the iirst step is preferably to take the rectangular plate A, (shown in Fig. 1,) of, for example, the thickness of three-eighths or half an inch, and with suitable formers bend the sides on the dotted lines D to produce ilanges d at right angles Atie-bar to receivesaid bolts.

to the body, which anges taper from the center toward the ends. Two holes E are then punched in the long axis of the plate, and said plate is split on said axis from the holes E to the ends to obtain four branches F. Each pair of split ends or branches F is then spread apart, as shown in Fig. 2, the required width of the column-bolts of the truck, and holes g are` punchedl in the branches of the The ends of said branches are turned up and provided with lips h, as usual. The tie-bar is arched toward the middle of the length to keep the center of the pull through the center of the material and also to permit water to easily drain off from its top. much stronger than the tie-bars obtained from plain iiat bars. A tie-bar of this form with tapering anged edges can also be made of cast metal.

Having now fully described myinvention, I claiml. A tie-bar for car-trucks consisting of a plate having its body forked at each end and divergent into two branches, the two edges of said body and the outer edge of each branch The tie-bar thus obtained is anged at right angles to the bottom of said W.
