' DRAFT RIGGING.

APPLIGATION FILED DEG. 7, 1911.

The cheek l also with an aperture of each its forward end. A flange 44 V 3S' and at its central portion 45 that these members be provided with The length of the retaining element is less than the range of travel of the followers so that it'does not sustain any of the burden incident to either bufing or pulling stresses. plates 35, 36 are riveted to the sills. Each is provided with a rear stop shoulder 37 for engagement-by the rear follower and a forwa'rd stop shoulder 38 for engagement by the forward follower, and intermediate shoulder 39, 40 for limiting the forward movement of the rearfollower and the rearward movement of the forward follower. The cheek plates extend forwardly beyond the apertures in the l5 sills which accommodate the key 24 and are themselves apertured,as shown at 41 to` receive the key, the aperture lof each being surrounded by an outstanding iange 42 which enteis the sill aperture as a bushing. The

cheek plate is also surrounded by aninstanding iange 43, which, as shown, is lower at its rearward than at extends forwardly from the outer edge of the shoulder with the iiange 43 which braces strengthens the shoulder.

\ carry iron 45 is bridged across between the sills 10, 1l passing under and supportand greatly 30A ing thezdraft rigging, the yoke sliding thereon. This carry iron is detachably connected with the sills by means of bolts and is applied after the rigging has been raised to its proper position.

While I have shown and described a preferred form of construction embodying the various features of my invention, it will be understood that I do-not limit myself thereto as various changes can be made without 40 departing from the scope of the invention;

as for example, while the inner faces of the p top and bottom members of the yoke are shown as concave it is essential only, for

the purpose of holding the springs in place,

standing projections or flanges at or adjacent their edges.

The key 24 which secures the coupler bar is connected I to the. yoke is permitted a longitudinal movement with reference to one of these inem.- bers in order that the coupler bar may move inward 'under buing stresses, the yoke remaining stationary as. its rearward end is engaged directly with the buliing shoulders 37. As shown, this movement of the key is with reference to the yoke,the apertures inthe side plates 22, 23, being elongated for this purpose.

I claim as my invention- 1. In`a draft rigging, in combination, a

yoke having laterally projecting shoulders for engaging draft lugs, whereby longitudinal pressure on the yoke exerted by the resilient element carried therein will bring it to central position.

2. In a draft rigging, in combination, a yoke having longitudinal members with concave inner faces, a pair of springs located side by side and one seated against the inner face of each of such members, and a spacing and locking element interposed be tween the springs and having laterally pro- `iecting tongues at each side engaging the two springs. i

3. In a draft rigging, in combination, a yoke having longitudinal members each having instanding marginal edges, a pair of springs located side .by side and one seated against the. inner face of each of such menibers, and a spacing and locking element interposed between the springs and having laterally projecting tongues at each side engaging the two springs.

4. In a draft rigging, in combination, a pair of springs located side by side, and a spacing and locking element, located between the springs, formed of a plate of pliable metal slitted from each side edge to form a bent to cries ofthe springs.
