To all lwhom "it may commi.'

Be it known that I, HENRY F. Porn, of Cleveland, Cuyaho a county, Ohio, have invented a new an useful Draft-Gear, of

. which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 shows in horizontal section a draft gear embodying my invention; Fig. 2 is a longitudinal'section thereof; Fig. 3 is a vertical section, on the line III--Ii of Fig. 2; and Fig. 4 is a sectional View illustrating a modification; Figs. 5 and 'arehorizontal sectional views, illustrating modifications of the invention.

In the drawings, 2, 2 are the center sills of the car-frame having an intervening' block or castiner 3, with a" curved head 4, on which the draf: -gear can swing radially. This block has a hole for the pivot in"l5, and has lateralsliding'1 bearing faces xr guidino the rear end of t gear;

Y 5'1sa frame which as shown' in the draw e sliding member of the draft has the formj'and funetionsof a coupler Hochet. but this isf not' essential, for the ame may be 'otherwise constructed, its functions, s'ofar as `thef'present invention is concerned', being ,to swing rdiilywitli the coupler and to cbnnect'the coupleF-with tue followers of tbedra'ft-rigging. Therefore, within the scope of iny Iinvention` the frame may be made of very different 'form and if desired may bei'ntegral with, or may be attached to, or form partof, the couplershank.A This construction is shown, for example, in Figs. 5 and 6, hereinafter described.

6 is the coupler, which is mounted within the pocket, referably by a pin 7 passing through a s ot in the coupler-shank, which may be backed by a spring 8. The yielding draft-rigging proper 9 may be 'of any suitable constructlon having springs with or .without friction element The draft-rigging which I illustrate inv Fig. 1 is set telescopically within' the hollow rear portion of the frame '5,' and is of the WVestlnghouse ty e which is a well known type of friction raft gear, and has a s ring 10, a front follower l1, and a rear fol ower 12, the rear face of which is curved and bears against the head LL, so that it may turn thereon.

The rear end of the frame or pocket 5 is connected to the follower 12, preferably by shoulders 13 on the frame, and the draft rigging is provided with a U-shape yoke 14, held at its open rear end to the head 4 by a pivot-pin 15, and extending around the front follower 11 of the draft-rigging.

The friction elements above described are shown in Fig. 2', f being wedge blocks which are moved within one another during buiiing and draft, and f are intercalated plates which act frictionally upon the surrounding bfi" or rase 9- 'The draft gear is. connected to the truck by guiding? connections shown in Fig. 1. These consista-'preferably of telescopically intercalated parts 20 and 21, having interi posed spring mechanism 22, these parts ex tending diagonally from the draft gear to the rtruck frame and beingpivotally conl nected at the ends, afs-shown at 23 and 24, hese connections being preferably constituted of ball-and-socket; joints. These spring connections serve to guide the draft, gear conformably to the motion'of the truck. When thecar to which my invention is applied is passing around curves the frame or pocketV 5 will swing freely on the axis 15. Then the coupler is subjected to buiiing stress, the frame 5 will move rearwardly, and by beat-inflr avainst the follower 11, will compress the diafbrigging 9 whose rear fol lower 1'3 is held from rearward movement by its abutment against the head 4. VDuring draft the forward motion of the coupler drawing with it the' frame or pocket 5, will by means of the shoulders 13 move the rear follower 12 forwardlyy so as to compress the springs of the draft-rigging which is thon held by the front. follower abutting against pin l5.

The rear end of the frame is preferable slotted, as at 1S, so that it may tit aronxfd the pin`15 and be guided thereby.

At thc front end ot' the fran-ie 5 are lateral stop projections which prevent buckling when two couplers are coupled togctheinl Like devices integral with the couplet' head are shown in Figs. 5 and G.

In the modilieation shown in 1"ig.-4, I strengthen the connections of -the yoke with the pin by providing the ends of the yoke 15 with journal-pieces or castings 19, through which the pin passes.

In the modilieation shown in Fig. 5, the coupler shank (3 is formed with a pocket G' at its rear end, into which the front cud of the coupler `frame 5 is tilted and to which it is secured rigidly byblis.

Many other changes may be made in the construction of the parts without departing from my invention. I do not claim herein the broad invention relating to a radially swinging draft member in connection with the stops at the outer sides ot the coupler head, the same bciii'g claimed in another copending application, u'eial No. 3G?,l0. I claim:

1. The combination with a draft` rigging including a yoke pivotcd to the car and yieldable draft and batting resisting m the yoke 1l, connected as above stated to the contained within the yoke, of a 'coupler longitudinally movable with respect to the yoke 'and associatedjwitb thegresisting means te compress the same during the ulling and bulling, and a sliding connection 1lne'tween the coupler and the truck of the car.

G. A draft gear having a coupler, a draftrigging, and a longitudinally movable coupler-carrying frame lextending rearwardly "5 from the coupler and I,having top and bottom and side members telescopieally inelosing the draft rigging, and carrying the front and rear shoulders for .the followers of the draft; rigging.

7. A car coupler extension having at its rearcnd a longitudinally extending cavity adapted to receive the yoke and springs of a draft rigging and provided with shoulders for tbe draft rigging followers and having 85 bearing faces at its rear end adapted to slide on tbc car frame.

8. A pivot member for a radial draft gear having a pivotal bearing for the draft `:gear and a sliding bearing for a sliding member 90 of the draft gea r,

9.

12. The combination with a draft rigging having front and rear followers, and yieldable draft and bnfling resisting means, a yoke pivoted to the ear frame and embracing the front follower, the front follower bearing against the yoke and the rear fol lower bearing against a fixed portion of the car frame at which the yoke is pivoted, and a coupler longitudinally movable with respect to the yoke and associated with theresxsting means.
