runway-can DRAFTILIGGING.

This invention relates to improvements inv frailway car draft riggings.

The object of the invention is to provide a draft rigging for railway cars so arranged 115l thatall the buflng and pulling strains .are transmitted to the car under-frame at points in the rear of the gear and. adjacent the body bolster.

In the drawing forming a part of this specification, Figure 1 is a part side `elevation, part vertical, longitudinal section of a draft rigging showing my im rovements in connection therewith. And Fig. 2 is a horif zontal, sectional view of the structure illustrated in Fig. 1, the section being taken above the gear and below the top sill plate,

. except at the forward end where the'section 'is lower to illustrate the slots for the coupler key.

In said drawing,v 10-10 denote channel shaped, center sills spaced the usual distance apart and extending between and rigidly connected thereto is`- an abutment yblock or castingv 11. The latter comprises a vertical 86 front face 12, top wall 13, intermediate wall 14, bottom wall 15,v and side walls 16--16, the latter being directly riveted to the sills. In the drawing is illustrated a friction .gear

of a well known type, the same comprising 4'0 a spring cage 17 and friction shell 18 inte- Ygrally formed, the friction shell being eitended toward the rear. Mounted within 4the spring cage aretwin springs 19 and withT in the Afriction 'shell are the usual friction shoes 20, wedge 21, anti-friction rollers 22 and preliminary spring 23. rIlie wedge engages a rear follower 24 which isV resisted from `rearward movement by the block 11, .the rear end of a horizontal' yoke 25 being o'linterposed between said'follow'er and said #blockThe arms of the yoke 25 are slotted at their forward ends to receive a coupler Y key 26 by whiclithe yoke is connected to a L i! draw bar 27, the latter directly abutting the it front end'of the spring cage 17 On the top Patented Feb. 4, 1919.

and bottom thereof, the combined spring cage'and friction cylinder is provided with a substantially T-shaped slot or recess 28 in which are adapted to be seated T-shaped front ends 29 of two links-30-3Q. links 30 are each provided with elongated slots 31 at their rear ends to accommodate a vertical, heavy pin 32 which passes through alined perforations in the walls 13, y 14 and 15 of the block 11. The links 30-30 65 'are preferably reinforced, as indicated at Vthe parts are assembled. A tie plate 35 is provided to support the gear proper and` the yoke 25 is supported by means of angle irons 36-36 secured to the inner faces of the sills, said angle irons being so disposed that their horizontal anges are uppermost and thus forni supports for the yoke. The pin 32 is detachably held in position by means of another tie plate 37 secured to the lower flanges of the sills. The parts are assembled by first placin the upper link 30 in position on the spring cageand cylinder, which is done by tilting the link relatively to the cylinder and inserting the T-heads in the pocket formed under the flange 34. The link 30 is then swung to horizontal position. The yoke 25 is placed in position on the supporting angles therefor, after which the friction 90 cylinder and spring cage with the upper link assembled therewith, are inserted through t-lie yoke and the parts moved rearwardly so that the link 30 will rest on the block 11. The follower 24 is then inserted 95 and last the lower link 30 is applied to the cylinder. Finally, the pin 32 is inserted and all the parts are lield up in place by the tie plates 35 and37. The draw bar can be inserted after the other parts have been asseinbled,as will be understood.

y In draft, it is apparent that the spring cage and friction shell will be prevented from forward movement by the links 30 on I account of the shouldered connections between said links and the friction shell. The yoke 25, however, moves with the draw bar and thus the .friction mechanism`- will `be actuated through said yoke and the follower y 24. Inbuff, the yoke 25 and follower 24 11'0 The so tained, since the tendency of the center sills,

to buckle between the end sill and the body bolster is thereby minimized.

I claim: f

1. In a draft rigging, the combination With draft sills, of a friction mechanism including a friction shell, of an abutment block mounted bet-Ween and secured to said draft sills and at the rear of the friction mechanism, a draw" bar,x a horizontal yoke connected to said draw bar and encircling the friction mechanism, a' portion of said yoke. passlngbetween the rear end of the fr1ct1on mechanism and said abutment block,

Geniet of this patent may be obtained for and links detachably connected to Vsaid friction shell and to said block to prevent forward movement of the friction shell but permitting rearward movement of the shell.

In a draft rigging, the combination l with draft sills, of a friction mechanism 1ncluding a friction shell, of an abutment block mounted between and secured to` said draft sills and at the rear of ,the lfriction mechanism, a draw bar, a yolke connected 3'5 to said draw bar and encircling' the friction mechanism, and links detachably' connected lto said friction shell and to the said block l l'to prevent forward movement 0f the frich n tion-shell, but permitting rearward lnove- 49 ment of the shell, the yoke being arranged horizontally and said links being also arranged horizontally, one above the other.

In Witness that I claim the foregoing I llave hereunto subscribed my name this 11th 45 day of July 1916.
