SPECIFICATION forming part of Letters Patent No. 596,128, dated December 28, 1897. Application filed May 18, 1897. Serial No. 637,119. (No model.)

To all whom it may concern.-

Be it known that I, WALDEMAR SCHEEL, manufacturer, a subject of the Emperor of Germany, residing at Schleusendorf, near Bromberg, Germany, have invented certain new and useful Improvements in Oar-Couplings, of which the following is a specification.

The present invention has reference to an automatic car-coupling which can be uncoupled from either side of the cars, thus doing away with the danger of the man getting caught between the cars while performing the uncoupling.

Figure 1 of the accompanying drawings shows a longitudinal section of the bottom of a car, with a view of the coupling parts A and B in place. Fig. 2 shows a top view of the coupling as arranged on either end of the car. Fig. 3 is a longitudinal section of the coupling parts A and B. Fig. 4 shows the threaded tenon q, the nut r, the worm z, the tenon s, the groove 6, and hole b Fig. 5 shows a section through the tenon q and the pins b Fig. 6 shows part of the receptacle ol and the drawspring In. Fig. 7 is a vertical section through the cylinder Z,with the channels a and of. Fig. 8 shows a longitudinal section of the tenon q, with the groove b and the hole b Fig. 9 is avie'w of the drum u with its axle t in section.

The car-coupling is made up of two parts A and B, being arranged alongside of each other on either end of the car. The coupling-hooks b of the part A are pivotally fastened at c to the tenon cl and are constantly pressed outwardly by the flat springs a. The noses f, coming in contact with the stops d, prevent the hooks b from opening too far. The cylindrical part 9 of the tenon d rests in the receptacle d and has a groovei provided around its circumference. A draw-spring is, fastened with one end to the receptacle d with the other end to the tenon d and lying within the said groove 1', tends to always keep the coupling-hooks b in the position shown in Fig. 3. The part B consists of a hollow cylinder Z, having two conical rings m n and two slots 0 0, these latter being arranged opposite each other and reaching to the foot of the conical ring n. The parts A and B are connected by the cross-piece p, from which branches off the threaded tenon q; The nut a", serving as a worm -wheel, is screwed partly upon this tenon q, partly fits loosely over the tenon s, the latter being fastenedto the bottom of the car. The nut r engages with the worm z, havin g the axle t. This axle t also carries the drum it, upon which the chain w, kept under tension by the spring 1), is wound when the axle t is rotated by the handle 00. WVhen two cars are being pushed together,the coupling-hooks b slide into the cylinderl and catch in the slots 0 0, thereby coupling the cars. One coupling part A and one coupling part B being provided on either end of the car a safe and secure coupling is assured.

In case the cars are to be uncoupled the nut r, by means of the handle or and worm z, is rotated,with the efiect of pushing part B farther into part A. The coupling-hooks b, pressed together by the conical ring n, glide into the channel or groove a, Fig. 3, which latter follows the inner wall of the cylinder Z slantingly for a quarter of a circle. The hooks b finally reach the bottom of this channel a, and by rotating the handle a; back into its original position, thereby withdrawing part A from within part B, are removed from the channels or grooves a Thedraw-spring 7c draws the hooks 19 back again in the position shown in Fig. 3. In the tenon q, branching off from the cross-piece 19, two grooves 17 are provided, being arranged opposite each other-and ending in the holes 5 Figs. 4 and 8. In either one of these holes I) a pin 6 Fig. 5, is inserted, which pins reach almost to the lateral edge of the car-b0ttom.- If the cars are to be uncoupled, these pins b are lifted out of the holes 12 and the threaded tenon q, and thereby the coupling parts A and B are free to be worked.

Having now particularly described and ascertained the nature of my invention and in what manner the same is to be performed, I

declare that what I claim is-- 1. In a car coupler the combination in a coupling part A of the coupling-hooks b,

ing pivotally fastened on the tenon d, the cy- I lindrical part g of which, having the groove 'i, rests in the receptacle 0?, the spring 70, fastened to the cylindrical part g within the groove 2' and to the receptacle d said hooksto engage in slots 0, o, in the hollow cylinder lot the coupling part B, the slanting groove outer surface of said nut r, the axle t, the ct, the straight groove a and the two conical drum u, the chain w and the spring 1), the axle 1o rings on and at, substantially as described. 25 to be actuated by the handle 00, substantially 2.
