SPECIFICATION forming part of Letters Patent N 0. 701,618, dated June 3, 1902.

Application filed November 20,1901. $eria1No.'83 019. v(No-model.)

T0 atZZ whom, it may concern:

a citizen of the United States,- residing at Buffalo, in the county of Erie and'State of New York, have invented new and useful Improvements in Draw-Bar Attachments, of which the following is a specification.

This invention relates more particularly to a draw-bar attachment for railway-cars in which the draw-bar is pivoted to swing laterrally and is provided with side springs which yieldingly retain the draw-bar in a central position and permit the same to swing' to either side of said central position to accommodate itself to the position of the car and allow of couplin s on curves. In such drawbar attachments of which I am aware coilsprings are usually arranged at the opposite sides of the draw-bar, and the lateral movement of the draw-bar is determined by the length of the spring or springs at each" side thereof, thus requiring long springs where a considerable lateral movement of the drawbar is necessary or desired.

The object of the present invention is to provide a draw-bar attachment in which a great or extended lateral movement or swing of the draw-bar is possible without necessitating the employment of unduly long springs.

In the accompanying drawings, consisting of two sheets, Figure 1 is a longitudinal vertical sectional elevation of a draw-bar attachment, illustrating my invention. Fig. 2 is a plan view thereof, partly broke'n away. Fig. 3 is a transverse sectional view on the line 3 3, Fig. 2. Fig. 4 is a sectional view on the line 4: 4:, Fig. 3. Fig. 5 is an end elevation,partly in section,of the attachment,showing the draw-bar in its side position; Fig. 6 is a plan View, partly in section,with the draw bar in the position shown in Fig. 5.

Like letters of reference refer to like parts in the several figures.

A indicates the coupler, and B the drawbar or stem, which at its inner or rear end is pivoted in any suitable manner, so as to permit its forward end to swing laterally or horizontally. In the drawings the rear end of the stem is shown to be pivoted in a pocket or recess in the front side of a bracket C, secured fto'the under side of the draft-sills by a ver- Beit known that I, WILLARD F. -RIICHA RDS,

ticalj'pivot-bolt D, passing through openings in the end of the stem and inthe bracket. The forward end of the draw-bar is confined between an upper transverse guide bar or plate E, secured to the under side of the end sill, and a lower supporting bar or plate E',

mounted to slide upon the yoke-bar E between the upright end portions 2 and which are provided with abutments F, which extend upwardly above the yoke E on opposite sides of the draw-bar B. The lower or body portions of the spring-pockets preferably extend below the bar E, and each is provided in its outer side with a recess or socket, in which is seated the inner end of a coiled spring I.

J represents a transverse rod or bar which is arranged horizontallybelow the bar E and passes through openings in the inner adjacent ends of the spring-pockets. The rod or bar J extends outwardly through the coiled springs I and is provided at its outer ends with stops or shoulders, against which the outer ends of the coiled springs bear. For this purpose the opposite ends of the rod or bar are preferably screw-threaded and provided with collars j and retaining-nuts 7' screwed onto the screw-threaded ends of the ,rod or bar J. The springs I encircle the rod orbar and are confined between the collars j at the outer ends thereof and the inner ends of the sockets in the spring-pockets.

It represents a stop-bar secured to the under side of the bar E between the inner ends of the spring-pockets and formingstop-shoulders, against which the inner ends of the spring-pockets are adapted to bearand are normally held by the actionvof the springs I.

Each spring-pocket is preferably formed of an upper anda lowermember, the lower member having npwardly-projecting front and rear arms f which straddle the bar 'E', and the upper member having depending lugs f which extend downwardly between the up wardly-projecting arms f 2 on the lower mem her to the upper face of the bar E and provide bearing parts for the spring-pockets. The outer ends of the arms f are preferably provided with downwardly-facing shoulders f against which the upper ends of the arms f abut. The members of the pockets are connected by means of a bolt Z, which passes through openings in the overlapping arms f and f This construction of the springpocket especially adapts the attachment for use in connection with a freight or passenger car orlocomotive-tender, in which the yoke or bar E usually employed is made of wroughtiron, bent into the form shown in the draw ings, inasmuch as the divided pockets can be applied to the bars E after they have been bent and secured to the sill.

When the draw-bar is swung to one side of its central positionforinstance, to the right, as shown in Figs. 5 and 6it engages the abutment of the right-hand spring-pocket and moves the latter and its spring along the supporting-bar E. The other spring-pocket is held from movement to the right by reason of its engagement with the stop it, but the rod or bar J is forced by the right-hand spring to the right, together with the pocket, and as this movement of the rod is opposed by the left-hand spring both springs are compressed to their limit before the movement of the right-hand spring-pocket and the draw-bar is arrested. It will thus be seen that the drawbar can move from the central position a distance substantially twice as great as would be permitted if the springs were mounted in a fixed position. The draw-bar can of course move to the other side of the central position an equal distance, as will be obvious.

I claim as my invention- 1. The combination with a movable drawbar, of movably-mounted springs adapted to be moved bodily by the draw-bar, means for limiting the movement of said springs in opposite directions, and a movable device connected to said springs whereby both of said springs are strained when the draw-bar is moved in either direction, substantially as set forth.

2. The combination with a laterally-movable draw-bar, of movably-mounted springs adapted to be moved bodily by the draw-bar, means for limiting the inward movement of said springs, and a device movable with said draw-bar and connected to said springs whereby both of said springs are compressed when the draw-bar is moved to either side of a central position, substantially as set forth.

3. The combination with a laterally-movable draw-bar, of movable spring pockets adapted to be moved by the draw-bar, a stop adapted to limit the inward movement of said spring-pockets, a coiled spring movable with each pocket, and a movable bar connecting the outer ends of said springs, whereby both of said springs are compressed, when the draw-bar is moved to either side of a central position, substantially as set forth.

4. The combination with a laterally-swinging draw -bar, and means for guiding the same, of oppositely-arranged spring-pockets having portions engaged by the draw-bar and adapted to be moved thereby, a stop arranged between said spring-pockets for limiting the inward movement thereof, a coiled spring carried by each pocket, a movable rod passing through said coiled springs and through openings in said pockets, and stops on said rod and engaging the outer ends of said coiled springs, substantially as set forth.

5. The combination withadraw-barmounted to swing laterally, and a guide-yoke for said draw-bar, of oppositely-arranged springpockets mounted on said yoke to slide laterally and having portions engaged by said draw-bar, a stop on said yoke between said spring-pockets, a coiled spring seated in a socket in each spring-pocket, a rod or bar passing through openings in said spring-pockets and through said coiled springs, and stops secured to the opposite ends of said rod or bar and engaging the outer ends of said coiled springs, substantially as set forth.

6. The combination with a draw-bar, and a guide-bar or the like therefor, of a springpocket member on one side of said guide-bar and having arms straddling said guide-bar, and a second pocket member bearing against the other side of said guide-bar and secured to said arms, said second member constituting an abutment for said draw-bar, substantially as set forth.

Witness my hand this 30th day of October, 1901.
