CAR-PLATFORM.

SPECIFICATION forming part of Letters Patent No. 389,550, dated September Application filed April 18, 1888. Serial No. 271,017. (No model.)

To all whom it may concern.-

Be it known that we, WILLIAM E. MGMAQK- IN and WILLIAM B. ORow, citizens of the United States, residing at Milburnton, in the county of Greene and State of Tennessee, have inventedcertain new and useful Improvements i n Extension-Boards for Freight-Oars, of which the following is a specification.

This invention relates to safety-platforms for freightcars, and its object is to provide a simple and improved device of this character designed to prevent persons falling between the cars, and which will possess advantages in point of inexpensiveness, durability, simplicity, and general efficiency.

- To this end ourinvention consists, substantially, in providing a spring -actuated platform at each end of the car, which will adapt themselves to the space between the same, and, further, in the details of construction,substantially as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of the end of a car having our improved platform applied thereto. Fig. 2 is a top or plan view of the same, the roofot' the car being broken away, the operation being show-n in dotted lines. Fig. 3 is an end elevation. Fig. 4. is a transverse vertical sectional view. Fig. 5 is a longitudinal vertical sectional view.

Corresponding parts in the figures are denoted by the same letters of reference.

Referring to the drawings, A designates the car, B the end thereof, and O 0 two of the cross-beams at the end supporting the roof. Upon the end B, near its top, is preferably secured a plate, D, provided with a series of horizontal slots, (1, on the same plane, and with an eye or perforation, (1, near each end, coincident with corresponding eyes or perforations, b, in the end B and through a continuous slot, 0, in the beam 0, provided with guides c. In lieu of this latter construction the beam 0 may be provided with a series of slots cor responding to the slots 1). Passing through these eyes or perforations are two horizontal parallel bars or rods, E E, preferably provided with rigid collars e e about midway their length Encircling the and between the beams O 0.

rear portions of these rods or bars E, between the collars e and the beam 0, are coiled springs F F, adapted to exert aforward pressure upon said rods or bars. Washers ff may be provided between the rear ends of the springs and the beam 0, as shown.

The rods or bars E are connected by a rod or bar, G, pivoted thereto, and upon said rod or bar G are pivoted a series of slats, H, having their inner or rear ends passing through the slots (2 and coincident slots in the end B and between the guides c on the beam 0.

I designates a rod or bar secured at its center to the rod' or bar G, and is bent or curved, forming two downwardly-extending loops, 9 g, as shown, and the ends are preferably secured by the pivots connecting the rods or bars E and G. The object of this rod or bar I is to prevent one platform from sliding under or above the other when the cars come together.

The operation and advantages of myinvention will be readily understood by those skilled in the art to which it appertains. The platform is normally held outside of the car the full distance permitted by the collars e by the springs, and when the adjoining ends of two cars come together the platforms will automatically adapt themselves to the space between them whether the train be going in a straight line or around a curve.

We claim as our invention 1. The combination,-with theends ofa car provided with a series of horizontal slots and an eye or perforation at each end of said series, and a beam within the car, provided with coincident perforations, of longitudinal springactuated bars disposed in said perforations, a transverse bar pivoted to the outer ends thereof, and a series of slats pivoted to said transverse bar and passing through the slots, substantially as and for the purpose set forth.

2. The combination, with a safety-platform for cars, comprising longitudinal spring-actuated bars and pivoted slats, of a bar secured thereto at the outer end and provided with downwardly-extending curved or angular portions adapted to prevent two opposing platforms from overlapping, substantially as set forth.

3. In combination with the end of a car, a ing the slots in the plate and coincident slots to plate secured thereto provided with a series of in the end of the car, substantially as set forth. slots and with an eye or perforation at each In testimony whereof we affix our signatures end of said series of slots, an extension-platin presence of two witnesses. form comprising two longitudinal rods or bars \VILLIAM E.
