Istruction of parts and devices and in the novel combinations of parts and devices herein shown and described and more particularly specifiedin the claim.

' In the accompanying drawing-formin a .part of this specification, Figurel is a on view, partly in horizontal section, of a .liiaft rigging embodying my invention. Rig. 2 is a central, vertical, longitudinal section on line 2-2 of Fig. 1.- Fi 3 is a vertical cross section on line 3-'-3 o Fi 1. Fig. 4

is a vertical cross section on hne 4+4of Fig. 1. Figi 5 is a detail, perspective view of the key and Fig. 6 is a detail perspective view, showing a. modification.

In the drawing, 1, 1-- are the center the front end sill, 3 the draw-bar, 4 the draft yoke, 5, 6 front and rear followers, 7, 8 twin springs arranged one above the other between-the followels, and preferably having smaller springs 9, 10 nested within them.

' (" heck plates 11, 11 are secured by rivets 12 on the inner upright faces of the center sill webs. The, cheek plates 11 each have front and -rear stops or shoulders 13, 14 for the followers to abut against and a lon itudinal channel 15 to receive one of the limbs of the horizontall dis osed yoke 4, which is connecte to t 1e draw-bar by a horizontal 'key 16, which extends througli'horizontal slots 17 in the center sills.-l and through corresponding slots'18 in the'cheek plates or stop castings 11. The cheelr plates '11 have horizontal bosses T 19/ .to give an extended bearing to the key 16. The key 16',is rovided at; one end with a bent li or h'ea 20 and at its opposite end with a tireaded bolt 21, the end of which may be upset'or riveted over nut 22 after the draft rig ing is as} sembled to prevent all possibi ity of its loosening or the bolt coming out. The horizontal key 16 is providedwith wear plates 23 to bear against the upright aces of the sills, 2

center sills, and thus relieve the retaining bolt and head of the key from wear and con- WILLIAM if. ma 0F Patentedlliay 19,1914.

sequent danger of the'draw-bar dro ping I down, in case the supporting key .16 s lould become displaced.

. The slots 18 in the cheek plates of the draft rigging, and 17 in the center sills are made long enough to allow for the necessary longitudinal movement of thedraw-bar. The slot 24 in the draw- bar 3 and 25 in the draft yoke 4 through which the key 16 asses are made somewhat wider than the iiey to enable the draw-bar to swing laterally as required when the train passes around curves. And the front ends 26 of the draft yoke 16 are furnished with double inclines 27 to facilitate their movement. 'As the draft yoke 4 is confined against lateral swinging movement by thecheek plates or stop castings-11, 11 between which it fits,

the longitudinally arranged springs 7, 8, 9 and 10 acting through the front follower against the rear end of the'draw-bar serves to automatically center the draw or restore it to its normal central ositi'on inthe longitu- 'dinal center line of tie car; the springs being normally under an initial compression when the draft rigging is assembled. The shoulders 28, 29 at the front and rear ends of the slots 17 and 18 in the center sills and cheek plates serve by engagement with the key 16 as, stops to limit the compression of' the springs after the springs have been compressed to" the full extent intended.

In the lnodification illustrated in Fig. 6,-

the wear'hlates 23 on the key 16 are furnished with integral .Iianges or jaws 30 through vrich the bolts 21 are passed; and

' in this construction, the key is made without any in gral head or lip.

The followers fi, 6 are each furnishedwith integra tuds or bosses 31 to fit within and serve to support the smaller springs in position. The removable tie-plate. 32 secured to the center sills by bolts 33 supports the larger springs j and the followers and also enables'the springs and followers to be removed and replaced when" desired without removing the key 16. A concavely curved. spacer 34 is interposed between the larger twin springs 7, 8 to support the upper one through the lower one and keep it in proper position. The draft yoke is supported by the cheek plates 11 by means of the longitudinal channel guides 15 therein, which re ceive and guide the draft yoke a's it re ciprocates back and forth.

I claim r In a draft rigging, the combination with a draw bar and horizontally disposed draft yoke, of eenter sills havingslots, a horizontal key xtendin' through the draw bar and .dra ft oke and t tough the slots inthe cen- .1 ter si s, said; key being adapted to move
