DRAFT-RIGGING.

Specification of Letters Patent.

Patented Nov. 12, 1912.

To all whom t may concern: Be it known that I, CYRUs L. .BUNDY, a citizen of the United States, residing in Kingsland, in the county of Bergen and State of New Jersey, have invented a new and useful Improvement in Draft-Rigging, of which the following is, a specification.

`My invention relates to improvements in friction draft rigging for railway cars.

This application is a division of my original application Serial No. Z98,824, liled May 2s, 1909.

My invention also consists in the novel construction of parts and devices and in the novel combination of parts and devices herein shown and described land more particularly specified in the claim.

In the drawings, Figure l is a side elevation partly in longitudinal section o f a friction `draft rigging embodying my invention; Fig. 2 is a plan View partly in horizontal section; Fig. 3 is a vertical cross section on line 3-3 ofFig. 1; Fig. 4 is a horizontal section on line 4 4' of Fi l; Fig. 5 is a detail perspective view o the lower friction block; Fig. 6 is a detail perspective view of the filler block of the yoke.

In the drawing A represents the center or draft sills of the car to which the draft rigging is applied, A1 the front sill and A2 the carrier iron. I

B is the coupler draw-bar, B1 the draft yoke and B2 the filler block at the rear end of the draft yoke, the same being preferably furnished with downwardly and rearwardly projecting supporting arms t which rest upon the removable tie plate C and thus support the rear end of the draft rigging.

D D are front and rear draft members secured to the'draft sills A in a suitable manner, as by rivets d.

F F are the followers, the front one abutting directly against the` rear end of the draw-bar and the rear one abutting directly against the draft yoke or the ller block B1 therein, if one isemployed. The followers F F have each oppositely inclined or wedgeing faces f f, the portipn of each follower upon which the wedge faces j being preferably inte al with the portion of the follower whic engages the draft members D. The inclines of the front and f are formed,`

rear follower'face each other, that is'to say the inclines are on theadjacent faces of the' followers. v

G and G1 are upper and lower friction blocks extending through the draft yoke B1 and each-having inclined or wedging faces `gV g engaging the correspondingv inclines or wedging faces f-'of the followers F. The upper friction block G'has on its upper face a channel or .recess g1l to receive and` ac'- commodate the upper limb-or member of the draft yoke and the lower friction block G1 has a corresponding but deeper recess or channel g2 on its lower face to receive and accommodate the lower limb or member of this application mea July 3o, 1910.

the draft yoke G1 and thus permit the upper 4 and the lower friction blocks to separate or move to and from each other as required under action of the opposing wedge faced followers F F.

H H are upright depending springs arranged below and actin yat their upper ends against the lower friction block G1 and at their lower ends against a spring seat or. bearing plate H1 which is connected by la pair of depending rodsK with the upper friction block G, an upper spring seat or bearing plate H2 being preferably interposed between the upper end of the springs and the lower friction block G1. The depending connecting rods K extend through the upper and lower friction blocks F F1 and I .the upper and lower spring seats or bearing plates H? H1 at the ends thereof and fit astride the springs. These connecting rods or bolts K are' provided with heads K1 at their upper ends and threaded nuts K2 Ka and a cotter VK1 at their lower ends.

As in my invention it is only the wedge faced followers and upper and lower friction blocks which fit within the draft yoke and as the spring is an upright or depending one arranged below the draft yoke, it will be readily seen by those skilled inthe art that my improved draft 'rigging is not l only very short and compact but also very accessible and capable of being easil. and quickly removed and replaced and a so of exceedingly simple construction and capable of being manufactured at small cost. The

shortness of my draft rigging adds greatl to its Vstrength and durabi ity and the dra t 'ido yoke is further strengthened by the drawat the rear of the draft yoke provided with bar followers and filler block and by reason downwardly and rearwardly projecting supof the short space between the followers. porting arms, one on each side of the draft Theuprightspring is ordinarily arranged yoke, the lower faces of said arms being 5 below thevdraft yoke and Vfriction blocks, as substantially flush with the lower outer face illustrated in the drawing and this is the of the yoke, substantially as specified.

preferred arrangement. CYRUS L. BUNDY.

I claim Witnesses: 'In a draft rigging, the combination with H. L. DIKEMAN, 10 a draw-.bar and draft yoke, of a ller block H. N. OCONNOR.
