UNITE STaTies PATENT EDWIN S. WOODS, OF CHICAGO, ILLINOIS.

SPECIFICATION formingpart of Letters Patent No. 691,038, dated January 14,1902. Application filed January 7, 1901. Serial No. 42,425. (No model.)

T0 on whom it may concern.-

Beit known that I, EDWIN SWOODS, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Draft-Rigging for Railway-Oars, of which the following is a specification.

The present invention relates to the double or tandem type of spring draft-rigging for railway-cars.

The object of the present invention is to provide a simple and effective connection between the tail-strap of the coupling-head and the centrally-arranged follower-plates of the tandem springs, all as Will hereinafter more fully appear and be more particularly pointed out in the claims. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is a vertical longitudinal section of a draft-rigging embodying the present in.- vention; Fig. 2, a horizontal section at line a; 00, Fig. 1.

Similar numerals of referen ce indicate like parts in both views.

Referring to the drawings, 1 1 represent the usual longitudinal draft-timbers, to which the cheek-plates or draw-bar stop-castings 2 2 are secured in any usual and suitable manner, 3 the end sill, and 4 the transverse supporting stirrup-plate of a railway-car. Said cheek-plates or draw-bar castings 2 2 will be of the usual counterpart construction secured to the draft-timbers in any usual manner, and each will be provided with a series of integral stops, lugs, or projections, comprisingin the construction shown a central stop 5 and front and rear end stops 6 and 7. Such series of stops, in connection with horizontal top and bottom flanges on the cheek-plates, form cavities in the opposing faces of the cheekplates,which receive and guide the respective ends of the series of follower-plates for the tandem-arranged springs 8 and 9, such follower-plates comprising in the construction shown the pair of central plates 10 and 11, arranged at and having bearing against the opposite sides of the central stop 5, and the front and rear follower- plates 12 and 13, having bearing against the front and rear stops 6 and 7, respectively.

14 is the usual draw-bar or coupling-shank, the rear end of which is adapted to have abutment against the forward follower-plate 12, as shown.

15 is the tail-strap, secured at its forward end in any usual and suitable manner to the rear end of the draw-bar 14 and preferably formed of a single piece of metal having a substantially rectangular cross-section and bent into a stirrup form, as shown, and which tail-strap is extended back a sufficient distance to embrace both of the tandem springs 8 and 9 and have hearing, by means of its vertical portion 16, against the rear face of the rear follower-plate 13.

In the present invention the novelty involved comprises the formation of such tailstrap 15 intermediate of its length with lugs 17 17, that are preferably formed integrally on the opposing faces of the two parallel members of the said tail-strap, and which lugs will be of a length approximating that of the central stops 5 of, the cheek-plates 2 and adapted to rest between thecentral pair of adjacent follower-plates 10 and 11, so as to engage either one or the other of the same to effect a compression of one or the other of the tandem springs under a pulling or a buffing strain, as the case may be.

With such improved construction a Very simple, efficient, and economical connection is afforded in that the necessity of the usual separate parts, with their attaching bolts and nuts, are entirely avoided and the same results attained in a much more efiective manner by a single-piece formation capable of ready and economical manufacture.

The present invention is equally adapted by a mere duplication of the opposed and integrally-formed lugs on the opposing faces of the two parallel members of the draw-head tail-strap for use in connection with the ordinary triple spring tandem draft-rigging of railway-cars in connection with a substantially like arrangement of parts.

Having thus fully described my said inven tion, what I claim as new, and desire to secure by Letters Patent, is-

1. In a draft-rigging, the combination with the tandem springs in a buffing or pulling action of the draw-bar, substantially as set forth.

2. In a draft-rigging, the combination with the draw-baigits tandem springs and followerplates, of counterpart cheek-plates secured to the longitudinal draft-timbers of the car and provided with stop-lugs for the followerplates, and a draft-bar tail-strap formed by a metal bar substantially rectangular in crosssection and provided with integrally-formed lugs intermediately arranged on the opposing faces of the two parallel portions of the same, which lugs are adapted to lie between the central follower-plates and adapted to engage one or the other of the same to compress one or the other of the tandem springs in a buffing or pulling action of the draw-bar, substantially as set forth. 7 i

3. In a draft-rigging, the combination with the draw-bar, its tandem springs and followerplates, of counterpart cheek-plates secured to the longitudinal draft-timbers of the car and provided with stop-lugs for the followerplates and a draft-bar tail-strap formed bya metal bar substantially rectangular in crosssection bent into a single-piece stirrup form and having integrally-formed lugs intermediately arranged on the opposing faces of the two parallel portions of the same, which lugs are adapted to lie between the central follower-plates to engage one or the other of the same to compress one or the other of thetandem springs in a bufiing or pulling action of the draw-bar, substantially as set forth.

4B. In a draft-rigging, the combination with the draw-bar, its tandem springs and followerplates, of counterpart cheek-plates secured to the longitudinal draft-timbers of the car and provided with stop-lugs for the followerplates, and a draft-bar tail-strap formed bya metal bar substantially rectangular in crosssection and having permanently-attached and intermediately-arranged lugs on the opposing faces of the two parallel portions of said strap which lugs are adapted to lie between thefollower-plates which separate one spring from another and are further adapted to engage one or more of the follower-plates thus effecting compression of one or more of the draft-springs, substantially as set forth.

Signed at Chicago, Illinois, this 5th day of January, 1901.
