DRA -GEAR FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Aug. 17, 1915.

Application filed July 9, 1914. Serial No. 850,030.

To all whom it may concern v Be it known that I, JAMEs M. MooRMAN, a citizen of the United States, residing at Marshall, in thecounty of Harrison and State of Texas, have invented new and useful Improvements in Draft-Gear for Railway-Cars of which the following is a specification.

This invention relates to draft-gear for railway cars and particularly to a drawbar, and the primary object of the same is to provide simple and effective means whereby the draw-bar may be positively associated with the car between the usual or any preferred form of sills or beams and having the parts for movably connecting the same disposed insuch manner that repair and substi tution of either of the parts may be effected without dissociating the draft bar from the beams or sills or the parts cooperating therewith and engaging the beams or sillsso as to expediterepairs of this character and avoid throwing a car out of commission for any considerable length of time. j

With this and other objects and advantages in view theinventio-n consists in the construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawing: Figure 1 is a side elevation showing a portion of the draft bar and the means for associating the same with the beams or sills of the car. Fig. 2 is a partial horizontal section taken through the structure shown by Fig. 1. Fig. 3 is a transverse vertical section taken through the center of the structure shown by Fig. 1.

The numeral 5 designates the ordinary or any preferred form of beams which are secured in parallel relation to the under side of the bed of the car or the framework supporting the car body and provided with hangers 6 suitably secured thereto and formed with longitudinal openings 7.

Engaging the openings 7 of the hangers 6 are a pair of followers 8 which are spaced a suit-able distance, and between the same are draft springs 9 which in the present instance surround draft rods or bars 10 secured at their forward ends to the front follower and having their rear ends projecting through the rear follower, as at 11 and 12, the springs having their opposite extremities engaging or adjacent to the inner opposing sides of the two followers. Each of the followers at opposite sides is formed with a guide tenon or lateral extension 13 movable in the opening 7 and longitudinally surrounding the followers is a yoke which in the present organization is composed of upper and lower members or sections 14 and 15 which respectively embrace the upper and lower portions and front and rear sides of the followers 8. The member 15 is formed with a rearwardly projecting arm 16 having an upwardly extending angular end 17 of a height above the arm equal to the thickness of a rear horizontal extension or arm 18 of the upper member or section 14 so that the latter will have its rear end abutting snugly against the angular extension 17 to obviate sliding movement of the one section or member of the yoke on the other. The forward extremities of the members or sections 14 and 15 of the yoke embrace the rear end of a draw-bar 19 which is pivoted to said extremities through the medium of a suitable bolt 20. The rear arm 16 and extension 18 of the members or sections 1+1: and 15 are secured by a plurality of bolts 21.

It will be understood that the yoke engages the followers 8 between the beams or sills 5 as clearly shown by Figs. 2 and 3, and the several parts of the draw-bar mounting as just explained may be readily associated with the beams 5 and hangers 6 and when it becomes necessary to repair any of the parts or to replace the spring the lower section or member 15 of the yoke may be removed by detaching the nuts from the bolts 20 and 21 so as to open the lower portion of the yoke and expose the followers and the draft springs 9 and rods 10 for repair or substitution as may be required, and afterward the said member or section 15 may be easily replaced and secured in materially less time than would be required to take down the whole draft bar structure in order to repair a broken or disarranged part. It is obvious that this convenience in reaching the parts of the draft bar mounting as just explained will materially reduce the labor and time ordinarily required to repair draft bar mountings as now constructed and as a consequence the car will not be thrown out of commission for any length of time nor will it be required to run the same on a siding adjacent to a repair shop or to pursue any extensive operations in order to correct or repair irregularities in the draft bar mounting or to substitute parts in the latter that may have been broken.

Another material advantage in the improved structure is the angular terminal or extension 17 of the arm 16 which prevents the upper section or member 14 of the yoke from moving on the lower member 15 in the event of shearing of the bolts 21, and by this means "also the bolts will be strengthened or rendered more durable by reason of the fact that material or shearing movement of the member or section 14: on themember or section 15 will be obstructed, and, furthermore, this provision also insures more durability and strength in the general organization of the draft bar mounting.

The improved device will be found excep tionally advantageous in car construction and it will be understood that changes in the proportions and dimensions may be adopted at will to accommodate various applications thereof. Furthermore, the use of the improved device is not in the least limited to any precise form of beam or hanger and it is proposed to mount the followers 8 together with the sectional yoke of the structure above specified in connection with any form of beam or hanger to which they may be adapted. 7

What is claimed is: a In a draft gear of the class specified, the combination with the bed of a car, of parallel beams secured to the under side of the car bed and provided with hangers having longitudinal openings, the beams and hangers being spaced from each other, a pair of followers having their opposite ends engaging the longitudinal openings of the hangers and provided with draft springs between them, draft rods secured at their forward ends to the front follower and having Copies of this patent may be obtained for their rear ends movably projecting through the rear follower, a yoke surrounding the followers and composed of upper and lower members respectively embracing the upper and lower portions andfront and rear sides of the followers, the lower member of the yoke being formed with a rearwardly projecting arm having an upwardly extending angular end, and the upper member of the yoke having a rearwardly projecting centrally located arm which terminally bears against the upwardly extending angular end of the lower yoke member, the yoke members being located between the beams, aplurality of bolts inserted through the rearwardly projecting arm of the lower yoke member and the arm of the upper yoke member in engagement therewith, the forward ends of the members of the yoke being separated to provide a recess therebetween, a draft bar having its rear end inserted in the said recess between the forward extremities'of the members of the yoke, and a single pivot bolt extending through the forward extremities of thefyoke members and the end of the draft bar therebetween, the lower member of the yoke being freely removable from beneath' the upper member of said yoke by disengaging the bolts connecting the rear arms of the yokes without detaching the entire yoke or the remaining portions ofthe draft gear.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. g
