'l Appli-cation filed March 16,` 1883. (No model.)

To all whom it may concern: Beit known that I, IRA C. TERRY, a citizen of the United States, residing at St. Louis and State of Missouri, have invented certain new and useful Improvements in Gar-Axlelrucks,

of which the following is a specication, reference being had therein to the accompanying 1 drawings.

My improvement consists in constructing a car-truck the cross-beams of which are formed of T rails, and in so arranging them that the lianges of the rails shall rest againstthe archbar and truss-bar, and with the heads of the rails preferably against each other, although ses I sometimes place them in the reverse position,

or base to base. s

Referring to the drawings making a partof y t l lthis specification, and in which like referencel letters indicate corresponding parts in all the views, Figure 1 is a side elevation of a truck embodyingmay invention. Fig. 2 is a sectional view online 2 2 of Fig. 1. Figs. 3 and 4; are detail views.` Fig. 5 isa side elevation of a slightly-different form of truck with my invention applied thereto. Fig. 6 is a section on line 6 6 ofFig. 5. Fig. 7is aside elevation of another modifiedform of truck, and Fig. S is a section on line S 8 of Fig. 7.

The wheels, axle-boxes, and bearings are of any ordinary or approved construction.

Ais the arch-bar. B is the truss4bar. V(l is the auxiliary arch-bar; D, the `draft bar or cord, and G are the cross-beams, which lform of T-rails, with the heads of the rails against each other. The anges of the rails composingthe beams are provided with the holes a b. (Shownin detail in Figs. 3 and 4.) The archbarhas holes c d, and corresponding holes, ej', are made through thetruss-bar, holes-c d through the auxiliary archbar, and holes g and h through the draft-bar. These holes or apertures through the beams and bars are for the passage of two lpairs of parallel bolts, E F, by means ofwhich bolts and their nuts a; x the parts are securelyclamped together.

Havingrst drilledthe holes through the tlangesof `the rails and through the arch and truss bars, I place two pairs of the rails at a suitable distance Y apart to form the beams,

` `loc-ating them between the arch and truss bars,

the bottom of the upper rail, which forms part l ofthe beam. being placed against the arch-bar,

and the bottom of the lower rail, which forms the otherpartof the beam,beingplacedl against j l bars4 will coincide. rlhe vbolts E and F are then passed through the holes and are clamped by means of the nuts x'xQboth bolts and nuts .being screw-threaded in the usual manner. If but two rails are used, the bolts are passed through the arch and truss bars only; butif the third rail is used below the auxiliary archbar,\as in Figs. 5 and 6, the bolts are passed through all the arch and truss bars. and also through the lower or draft bar. `I prefer, also, in case the third rail is used, to locate it so that the head ot' said rail shall bea-r against the auxiliary arch-bar, as shown. rails are used, the swinging bolster may be readily applied by means ot' suspended axleseats on top of the beams, whichare secured thereto by riveting or in any other suitable manner; orthe trucks may berigid, and spring` seats may be formed by means of suitable plates between the beams, as shown in Figs. 7 and S. They may be4 riveted to the lower rails or the upper rails, or to both.

l It will be seen-that the parts are securely clamped by bolts on each side of the rails, which are substantially parallel with each other, and which are passed through'thcilanges of the rails which form the beams, through the truss and arch bars, and are secured by suitable nuts, thus forming a strong, durable, and easily f constructed truck. The bolts bear against the heads of the rails which form the beams; or they are..` partially sunk in indenta' tions made in the heads of the nails.

In the accompanying drawings I have shown thebeams constructedof T-rails head to head, and I prefer to use them in this manner; but

Whether two or rthree I do not` wish to limit myself to `this form of i construction, as l sometimes place them in the reverse position, or base to base, so that the flanged portions ofthe rails shall be together, instead of the heads.

It is obvious that my invention is applicable s 2 l 275292 V e toA the .style oftruckshowndn-Figul, or to those represented by I `igsu7`and'S. Y

I am aware that what is known as channeliron,77 and also angle-iron, have both been used inthe construction of car-trucks; but neither has the form, the strength, or the functions of T-ironas beams for a truck, and I do not claim any such forms of iron.

Having thus fully described my invention, what I claim as new, and desire tosecure by Letters Patent, `is- 1. The combination, in a cartruck, of the beams formed of T-rails with the arch:v and vtruss bars, all seeured together by parallel bolts passed through or resting in recesses in theanges on both sides of the beams, substantially as setforth.

2. The cross-beams G, eomposed'of T-rails placedwith the anges of thefrails against the arch and truss bars, said parts being clamped at their ends. by means of bolts which are .passed through the arch and truss'bars,throngh v"IRA C. TERRY.
