TANDElVI-SPRING DRAFT-RIGGING FOR RAILWAY-CARS.

Specification of Letters Patent.

' iication.

Uur invention relates to tandem spring draft rigging for railway cars.

The object vof our invention is to provide a tandem spring draft rigging of a strong, simple, efficient and durable construction, and in which the side plates or stop castings shall be anchored to and combined with the car framework in a very firm, safe and secure manner.

Uur invention consists in the means we employ and herein shown and described for practically accomplishing this result, as more particularly set forth in the claims.

In the accompanying drawing forming a part of this specification, Figure l is a side elevation partly in central vertical section,

` of a tandem spring draft rigging embodying our invention. Fig. 2 is a plan view partly in horizontal section. Figs. 3, i and 5 are vertical cross sections on the lines 3 3, 4ta'- and 5*5 respectively of Fig. 2. Fig. 6 is a detail plan view of one of the tieplates. Fig. 7 is a detail perspective View of one of the side plates or stop castings.

In the drawing, A A represent the center sills or draft timbers or other longitudinal frame members of the car to which the draft rigging is directly applied, A1 the front or end sill, A2 the buffer block and A3 is a transversely extending abutment or member of the car frame at the rear of the draft rigging.

B is the draw-bar and B1 the draw-bar strap or yoke secured to the draw-bar by rivets and interengaging lugs or shoulders l b2 on the draw-bar. The draw-bar strap is furnished with a middle abutment block b3 having curved faces bt to engage the middle followers and secured in place by rivets b5. At its rear end the draw-bar yoke B1 is furnished with a curved loop Z9@ and a semi-cylindric filler block 57 to abut against the rear follower. and which is secured in place by a rivet bs.

C, C1 are tandem arranged. springs between tlie followers E El E2 E3.

D D are the side. plates or stop castings furnished with stops or shoulders d l1 d2 cl3 for the followers to abut against, and intermediate stops or shoulders Z4 Z5 Z6 Z7 to limit the compression of the springs by engagement with the followers. Each of the side plates or stop castings D has a forward outwardly inclined extension Z8 extending to the extreme front end of the car framework where it is provided with a lateral flange dg flush with the upright front face ofthe abutment block A2. Each of the side plates or stop castings D is also furnished with an integral rearward extension d10 having a right angle foot or flange Zu abutting against a shoulder a on the rear transverse frame or abutment member A3. Each of the side plates or stop castings D is also provided with upper and lower outwardly extending iianges c 12 and d, thus giving the side plate or stop casting a general channel form in cross section, while its inner face is left free from upper and lower flanges and substantially straight or smooth, excepting for the jogs, convolutions or bends which form the several stops and intermediate stops.

To afford an additional anchorage of the side plates or stop castings to the car frame, each of thev side plates or stop castings D is furnished with an integral upwardly projecting abutment ZM which fits against the front end of the longitudinal car frame sill or member A and in a suitable notch or recess al in the end or front sill A1.

The upper horizontal iange d of the outwardly flanged or channel shaped stop casting D fits under and abuts against the lower horizontal face of the car frame members A A1 and is secured thereto and to the buffer block A2 by vertical bolts F.

G G are also removable guides secured to the side plates or stop castings D by bolts g and upon which the followers rest and reciprocate.

H Il are tie plates extending between and secured to the side plates or stop castings D. These tie plates H are secured in place by bolts it extending through the horizontal iiange (Z13 of the side casting. Each or these tie plates H is furnished with a central longitudinal guide or channel h1 for the lower member of the draw-bar strap or yoke B1 to it and reciprocate in, and is provided at its outer ends with seats h2 to receive the lower horizontal flanges @Z13 of 1 the channel shaped stop castings D and with shoulders h3 for the outer edges of said flanges Z13 to abut against. The tie plates H are secured to the lower horizontal flanges (Z13 of the stop castings D by removable bolts h having threaded nuts h5 and keys he.

The longitudinal frame members A A of the car to which the side plates or stop castings D are secured are placed closer together than the length of the followers so that the ends of the followers will project under these longitudinal frame members of the car and render unnecessary any upper guide flange for the followers on the side plates or stop castings D, thus materially simplifying their construction.

H1 H2 are rear upper and lower reinforcement plates extending between and firmly secured to the upper Y and lower flanges CX12 Z13 of the stop castings D by rivets L7. And H3 H4 are front upper tie plates secured to the upper flanges dm of the stop castings D by vrivets it?, the tie plate H4f having an upright integral flange H5.

H6 is the front carry iron supported by the bolts its.

The inner upright faces of the stop castings D, it will be seen from Fig. 7 of the drawing, are substantially straight and smooth except for the upright recesses D1 therein to receive the ends of the followers. And, as will be seen from Fig. 2, these recesses D1 and the stop shoulders d d1 cl2 Z1 (Z4 d5 d and Z7 are formed by simple bends in the-main upright web D3 of the stop casting. This gives the stop casting an exceedingly simple, strong and effective form free from projections or flanges on its inner face and of a substantially channel form in cross section at all parts of its length.

'We claim 1. In a tandem spring draft rigging, the combination with the draw-bar, draw-bar yoke, tandem arranged springs and followers, of. outwardly turned, channel shaped stop castings, each furnished with transverse bends in the main, upright web thereof forming stops for the followers to abut against, said web being also provided with further transverse bends forming intermediate stops for the followers to abut against to limit the compression of the springs, the vertical faces of all the bent out portions of the web and of the intervening portions between the bent out portions being flat and unbroken, and the upright recesses intervening between the stops extending entirely across the stop casting from the upper to the lower face thereof and adapted to receive the followers, the castings being secured to the under sides of the draft sills of the car by bolts extending through the upper flanges only of the castings, substantially as specified.

2. As an article of manufacture, a stop casting for railway draft rigging, the said stop casting comprising a channel-shaped member, the flanges of which are arranged to be turned outwardly when applied in position, said channel-shaped member being furnished with transverse bends in the main upright web thereof forming stops for the followers to abut against with intervening upright recesses extending across said member from the upper to the lower face thereof, said recesses being arranged to receive the followers, and the flanges of said channel-shaped member being entirely to one side of the main web thereof and the stop portions to the other side of the main web, substantially as specified.

3. As an article of manufacture, a stop casting for railway draft riggings which comprises a channel-shaped member, the flanges of which are arranged to be turned outwardly when said member is applied in position, said member being furnished with transverse bends in the main upright web thereof forming stops for the followers to abut against with intervening upright recesses extending across said member from the upper to the lower faces thereof, said recesses being adapted to receive the followers, the flanges of said member being located entirely to one side of the main web and the stop portions to the other side of the main web, said member being provided with a forward extension having a laterally extending lange adapted to lie flush with the front face of the car-frame work, said member being also provided with a rearward extension adapted to abut against the transverse member of the car-frame at the rear of the draft rigging, substantially as specified.
