Letters Patent No. 114,587, dated May 9, 1871.

IMPROVEMENT lN RAILWAY-CAR AND ENGINE-TRUCKS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE FRED. Monsn, of Portland, in the county of Cumberland and State of Maine, have invented a new and useful Improvement in Railway-car and Engine-Trucks and I do hereby declare the following to be a i'nll, clear, and exact description thereof, which will enable others to make and use my invention, reference being bad to the accompanying drawing forming part of this specification, in which- Figure 1 shows a side elevation of the truck-frame with my improved sway-beams.

Figure 2 shows an end elevation of the truck-frame, showing the sway-beam and the spring for maintaining the sway-beam in central position.

Figure 3 shows same view as fig. 2, with another varietyof spring for maintaining the sway-beam in a central position, and a different variety of riding springs.

Same letters show like parts in all of the figures.

My invention consists of an improvement in railroad-car or engine-trucks, by means of which the lateral motion so desirable in railway cars can be more che. ply attained, and can also be obtained with certain forms of truck-frames in which the ordinary swing-beam cannot well be used. This lateral motion in railway cars is usually obtained by hanging the beams of the truck that carry the bolster-springs upon links which swing laterally tothe desired extent, being brought back to position by gravity. 111 these cases both the upper beam of the truck upon which the car is supported and the lower beams supporting the springs swing, being suspended by the links above referred to, said links hanging on pins supported by the cross-timbers of the truck.

In my inuention it is.only the upper beam of the truck, carrying the center irons and car-bearings, that moves late-rally, the lower beam supporting the springs being rigidly fastened to the side frames of the truck. The upper beam, therefore, having play allowed by the side frames, sways laterally to the motion of the car, rocking or rolling on the springs, and is brought back toposit-ion by the springs F F.

The amount of swaying or lateral mot-ion is governed by the guides G G. This upper or swaying beam is allowed to freely rise and settle on the springs by the play allowed at the guides.

A is the sway-beam;

B is the rigid beam carrying the springs;

O is one of the springs;

D, the side of the truck-frame; and

E E are the axle journal-boxes.

A is the sway-beam;

B, the rigid beam;

0' C, the riding springs D D, the sides of the truck-frame; and

E E the axle journal-boxes.

F in fig. 2 and F in fig. 3, respectively, show the springs for retaining or bringing back the sway-beam to a central posit-ion. It will be observed that the form of the spring for the accomplishment of this purpose is varied to adapt it to varying kinds of trucks.

In the drawing fig. 2 shows a metallic spring working in a guide in the sway-beam, so that it is bent by the motion of the beam, and brings the same back to a central position by resuming its own position.

In fig. 3 a rubber spring is represented, which is compressedby the swaying of the beam, and restores it to a central position by its own elasticity.

I do not desire to limit myself to the employment of either of the devices shown.

I do,not claim the application of springs to each side of the bolster-beam, as set out in A. Bridges patent, May 27, 1862, N 0. 35,410. My invention, moreover, relates not to a swinging bolstenbeam, but to a sway-beam.

Neither do I claim recessing the bolster in the middle on each side in such manner that it can besuspended on half-elliptic springs occupying the recessed spaces; patent of J. L. Gill, January 23, 1866, No. 52,158.

Neither do I claim the construction of a bolsterbmfer or spring made with a projecting heador plunger to act upon the plated face of the side truck framepiece, nor the springs bearing-plate or table and sockets for carrying the springs, as set forthin P. G.Gar-

.diners patent, No. 98,049, December 21, 1869.

What I claim as my invention, and desire to secure by Letters Patent, is-

The swaying beam A A, arranged to rock or roll laterally' on the springs or on suitable rockers or rollers, in connection with the springs FF and guides G G, as herein set forth.
