DRAFT-RlGGING.

SPECIFICATION form-ing part of Reissued Letters Patent No. 12,334, dated March 28, 1905. Original No. 723,169, dated March 17, 1993. Application for reissue filed November 2, 1903. Serial No. 179,644.

To rrr/.lwhom t may concern.-

Be it known that I, ARTHUR LIPsoHU'rz, a citizen of the United States, residing in the city of St. Louis, Missouri, have invented certain new and useful Improvements in Draft- Riggings, of which the following is a specification.

This invention relates to draft-rigging for railroad-cars, and has todo with the construction and arrangement of car-couplers and the springs therefor. .1

The object of the invention is to improve the construction andarrangement of the tailstrap and the spring-followers' for car-couplers; and with this end in view my invention consists generally in the combination of the car-coupler, with the tail-strap therefor provided with a division -plate, the cushionsprings, the fore and aft follow rs for each, the stationary stops for' said followers, land a central stem extending between the forward followers of the two spring-cushions.

My invention furtherconsists in particular constructions and in combinations of parts, all as hereinafter more fully described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming a part of'this specification, and in which Figure 1 is a vertical section of a draftrigging embodying my invention. Fig. Z is a plan view thereof on the lines ma' of Fig. 1, the upper part of the strap being cut away.

As shown in the drawings, Q represents the large end on the shank of the coupler.

2' is the tail-strap, which is secured to-the shank. This strap embraces both cushionsprings 3 and f1. In this connection it may be stated that singlesprings are shown in the drawings for the sake .of clearness, while in practice the springs are nested-in each space or compartment within the strap. The strap sponding to the lugs commonly employed, but here. taking the form of an actual bridgeplate between the top and bottom of the strap. This plate is firmly secured to the strap by the rivets and is provided with a central hole 7.

8 9 are the fore and aftI follower-plates of the forward spring, and 10 and 11 are the fore and aft follower-plates ofthe rear or inner spring. These plates, asshown in the plan view, Fig. 2, are wider than the strap and extend out into the stop-channels 12, which are secured upon the inner sides ot' the draft-sills 22 ofthe car. The channels 12 are each provided with three,stops l3.,11, and 15 for the followers 8, 9, and l1. The followers 8 and 9 are arranged between the ste ps 13 and 14? while the followers 10 and 11 are arranged between the stops 14 ancl=1:15. The rear follower isprovided with the usual center studv 16 to hold the spring or springs in place. As usual, this stud-'is in th-form of'a hollow rivet that is secured in central opening of theffollower-plate 11. A 'similar central stud 17 is provided in the forward plate 8, while the follower-plate 9 is provided with a large hole 18. The follower-plate- 10, which is forward of the rear spring, is provided with a rod, shaft, or stem 19, which is preferably integraltherewith and extends forward through the hole 7 in the partition-plate 5 and throughthe hole 18 in the follower 9. The forward end of the stein 19 is reduced in size and is seated in the step 20, provided therefor in the end of the stud 17. In the forward compartment of the strap this Stem serves to hold the spring or springs centrally in place, andthe'rear side of the follower 10 is provided with a recess 21 to hold the spring, in this respect corresponding to the stud 16. As shown, the follower, 9 normally rests against the partition-plateorlug 5. The force of the springs tends to hold the strap with its plate 5 exactly opposite the stop-lugs 14.

The o peration of my invention is as follows: The parts being in position shown in Figs. 1 and 2 and a pull being exerted upon-the coupler to draw the strap forward, it is evident that the follower 11 will be drawn forward by the rear end of the strap, while the follower 9 will be forced forward against its spring by the lug or plate 5 on the strap.
