DRAFT MECHANISM FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 555,520, dated March 3, 1896.

Application filed gus 22, 1895. Serial No. 560,149. (No model.)

for railway-cars, to dispense with the usualdraft-timbers, and to relieve the car-body of strain.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a reverse plan view of a car provided with draft mechanism constructed in accordance with this invention. Fig. 2 is an enlarged horizontal sectional view of one end of the car. Fig. 3 is a detail perspective view of the attachmentframe. Fig. 4 is a reverse plan View illustrating a modification of the invention.

1 1 designate similar car-couplings arranged at the ends of a car 2 in the usual manner, and provided at the inner ends of their drawbars with oppositely-disposed perforated lugs 3, receiving the ends of continuous draft-rods 4, which extend from one end of the car to the other and which pass through attachment-frames 5; The attachment-frames 5 are constructed of suitable metal and are oblong, being located adjacent to each end of the car and being secured to the framework thereof by fastening devices 6 disposed vertically and passing upward through the sides of the attachment-frame. Each attachment-frame is provided at its ends and in an intermediate cross-piece 7 with registering-perforations to receive the continuous draft-rods 4.

ends of the attachment-frames and the rear ends of the draw-bars, transverse-plates 10 being arranged on the rear ends of the drawbars and affording bearing-surfaces for the outer ends of the coiled springs. These springs are partially received within sockets or recesses 11 of the outer terminals of the attachment-frames, and the two sets of springs cooperate with each other to provide cushions for the draft mechanism in pulling and backing. In backing the springs at the front end of the car form cushions, the front draw-bar being capable of inward movement on the ends of the draft-rods, and during the opera tion of pulling the rear springs cushion the draft mechanism.

As the draft-rods extend the entire length of the car or are continuous, being connected with both car-couplings, the strain incident to drawing a train of cars is not exerted on the car-bodies, and the attachment-frames obviate the necessity of employing the ordinary draft-timbers.

Any form of car-coupling may be employed, but in the accompanying drawings an automatic car-coupling of the Janney type is illus trated.

In Fig. 4 of the accompanying drawings is illustrated a modification of the invention. The draft-rods are not continuous, and in order to cushion the draft mechanism in pulling coiled springs 12 are employed and are arranged on the rear terminals of short draftrods 13, a plate 14 being arranged on the draft-rods in rear of the springs 12, and the draft-rods being threaded and provided with nuts 15. 1

The car-couplings are provided at the rear ends of their draw-bars with rearwardly-extending pins 16, detachably secured to the draw-bars in suitable openings thereof and arranged in openings 17 of the outer ends of the attachmentframes, and forming guides and supporting the car-couplings.

It will be seen that the draft mechanism is simple, strong and durable, that it is adapted to be readily applied to railway-cars, and that it is capable of relieving the car-bodies of strain incident to drawing the train of cars.

Changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.

hat I claim is i I 1. In a draft mechanism for railway-cars, the combination with a car, of an oblong frame constructed of metal, composed of integral sides and ends and secured to the car, the sides of the frame being provided at intervals with vertical openings and the ends of the frame having aligned longitudinal openings, parallel draft-rods arranged in the longitudinal openings and extending in advance of the frame, a car-coupling provided at opposite sides of its draw-bar with perforated lugs receiving the draft-rods, and cushion in gsprings interposed between the draw-bar and the frame and disposed on the draftrod, substantiallyas described.

2. In draft mechanism for railway-cars, the combination of an attachment-frame designed to be secured to a car-body and provided with longitudinal openings, a car-couplin g provided 011 the inner end of its draw-bar With laterally-disposed perforated lugs, draft-rods passing through the attachment-frame and through the perforations of the said lugs and secured to the latter, a plate arranged on the draft-rods contiguous to the draw-bar, and spiral springs disposed on the draft-rods and interposed between the attachment-frame and the plate, substantially as described.

' In draft mechanism for railway-cars, the combination of an attachment-frame provided with longitudinal openings, a draw-bar provided with opposite lugs, draft-rods passing through the openings of the frame and connected with said lugs, spiral springs disposed on the draft-rods and interposed between the draw-bar and the frame, anda pin secured to the draw-bar and extending rearwardly therefrom and guided in an opening of the frame, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

HENRY H. MARSHALL.
