ELWOOD H. NEWMAN, OF ASBURY PARK, NEW JERSEY, ASSIGNOR TO 'HIMSELF AND JOHN 'A. GITHENS, OF SAME PLACE.

' SHOE ATTACHMENT FOR CAPT-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 373,247,.dated November 15, 1887.

' Application filed March 19, 1887'. Serial No. 231,588. (No model.)

" To all whom, it may concern:

Be it known that I, ELWOOD H. NEWMAN,

of Asbury Park, in the county of Monmouth and State of New Jersey, have invented a new and Improved Shoe Attachment for Car- Trucks, of whichthefollowing is a full, clear, and exact description.

My invention relates to an improved shoe attachment for car-trucks, and has for its ob- IO ject to provide a means for preventing the 4 longitudinally-flanged shoes to a car-truck,

and in the construction and combination of said shoes, aswill be hereinafter more specifically set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the applied device; and Fig. 2, an end view thereof, the

truck being shown in section on the line w w of Fig. 1. Fig. 3 is a longitudinal vertical section through an unattached shoe.

Between the wheels of a car-truck, A, a slight distance above the track a, shoes B are held insuspension at each side of the said truck.

The shoes B are preferably made about three feet in length and about twelve inches in width, or of such dimensions to readily find place between the wheels of different styles of trucks; or, if the space intervening the wheels is not found convenient, attachment maybe made upon each side and to a suitable end extension of the truck.

The shoes B are provided with integral longitudinal side flanges, B, beveled ends 12, and two or more friction -rollers, 72, journaled transversely therein, in such manner that the surface of the rollers will project but slightly beyond the under face of the shoes. The said rollers 12 are not, however, necessary to the completion of the invention, and may be'omitted without materially affecting the usefulness of the shoe. y

In the accompanying drawings the device is illustrated as applied between the Wheels of a truck. In this event the shoes are held in position slightly above the track, and at each side by a more or less U-bar, O, carrying one of said shoes B at each end, and attached to a beam, 0, extending centrally and transversely the under side of the truck-body, each shoe being securely braced against lateral play by inner brace-rods, D, which rods are attached to each end of the car-truck body, and, projecting downward,crossing one another, asshown in Fig. 2, are rigidly secured to the inner longitudinal edge of the shoe, as will be observed by reference to said figure. Similar brace-rods, D, are also provided, fastened upon the outer longitudinal edges of the shoe, as shown in Fig. 1, attachment at each end of said brace D being preferably madeto the journal-boxes. of the truck, and an additional vertical brace-rod, d, may, if found desirable, be attached centrally to the outer longitudinal edge of said shoes and to the carriage-bar of the truck. (See Fig.1.) As heretofore observed, however, the shoes may be secured to project from each end of the truck, instead of the center, and the bracing may be varied to suit the exigencies of different styles of trucks without departing from the spirit of the invention.

In operation should a car or cars become derailed by jumping the track because of obstructions thereon, a broken rail, or a misplaced switch, the shoes will, by engagement with the track upon each side through one flange, B, or the other, retain the wheels parallel with and in close proximity to the said' track, thereby preventing the cars from falling down an embankment or from a bridge or trestle, and the friction of the shoes upon said tracks will cause the several cars to draw so heavily that the engineer will at once be advised thereby of an accident.

The shoes may be attached to any truck without material alteration in a simple and expeditious manner.

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

The combination, with the truck A, the

transverse beam 0, and the U-bar O, of the shoe, and the vertical braces d, connecting the shoes B, secured to the ends of the beam berods D with the carriage-bar of the truck, subtween the wheels, and having opposite longistantially as set forth.
