DRAFT RIGGING.

Application led February 4.-, 1924.

ITo all 107mm t may concern.:

Be it known that l, Brin-:s lV. Kiper., a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Draft Rigging; and I do hereby declare the following to be a full, clear, and exact description of the invention, such` as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway draft rigging and more particularly to an improved connection between. the yoke and coupler.

One of the principal features of the present invention is to provide a connection between the yoke and coupler in which is provided a relatively large and increased bearing area for the key connecting said elements while maintaining free angling movement of the coupler butt.

Another object ofthe invention consists in providing a very strong and durable connection between the coupler and yoke, said connection providing a greater bearing area for the coupler key and involving enlargements or projections arranged upon the inner opposed faces of the yoke arms adapted to cooperate with pockets or depressions formed in opposite sides of the coupler shank provided at the forward end of the coupler key slot.

A. further object of the invention is to provide a railway draft rigging embodying a vertical yoke attachment in which opposite Haring walls of the hooded head are provided with inwardly extending reinforcing projections arranged at the forward ends of the key slots and adapted to provide increased `bearing area for the forward edge of the key, the shank of thev coupler being readily insertible between said projections and having cut away portions in which said projections may move upon angling of the coupler under service conditions.

lilith these and other objects in view, the invention further consists in the combination, construction and arrangement of the several parts hereinafterl set fort-h.

ln the drawings illustrating the invention, the scope whereof pointed` out in the claims:

Figure l is a view in horizontal section Serial No. 690,456.

of a railway draft rigging showing a yoke member and coupler constructed in accordance with the invention.

Figure 2 is a detail horizontal sectional view on an enlarged scale through the forward end of the yoke member and the shank of the coupler.

Figure 3 is a detail. vertical transverse sectional view on the line Bwl of Figure 2.

Referring to the drawings in which corresponding reference characters designate similar parts in the several views, the numerals l-l indicate center sills or draft sills of the railway draft rigging, said draft sills being suitably spaced and provided with the front stop members 2 and rear stop members 3 between which is interposed the cushioning mechanism diagrammatically illustratedby dot and dash lines. The forward ends of the draft sills are slotted, as at 4i, said slots registeringjwith slots 5 provided in the front stop members.

In the embodiment of the invention illustrated there is shown a vertical yoke 6 having a hooded end 7 into which is fitted the shank of the coupler 8. While I have shown the invention as primarily designed for vertical attachments, it will be understood that the invention is not limited to the construction set forth herein.

The hooded end of the yoke is provided with oppositelydisposed outwardly flaring walls 9, each of said walls being slotted, as at 10, and having inwardly extending enlargements or projections ll arranged at the forward ends of the slots. rPhe projections ll are designed to reinforce the forward ends of the yoke and provide relatively large bearing areas against which the forward edge of the key l2 contacts on draft. The projections border the forward end of the key slots in the side walls of the yoke head, said projections extending slightly rearwardly of the forward end of the slot and continuing forwardly to the front of said side walls.

The coupler, and more especially the shank thereof, is provided with depressions or cut away portions 13 disposed upon opposite sides thereof, said depressions being located adjacent the forward end of the key slot l-i in the coupler and being generally shaped to conform to the projections l1 with which latter they are designed to cooperate. The depressions or cut away portions 13 extend forwardly and rearwardly of the `front wall of the key opening or slot let and are designed to receive the projections or enlargements 'l1 upon swinging movement of the coupler with respect to the yoke head.

yoke constructed in accordance with the present invention is capable of receiving a coupler of standard dimensions between the projections or enlargements 1l, it being observed that the spacing now maintained between the inner opposed faces of the yoke arms and the adjacent sides of the coupler is utilized `to provide for the increased bearing area, the adjacent portions of opposite sides of the coupler shank being pocketed or depressed whereby an effective spacing of the yoke and coupler is maintained. It will be observed that the rear bearing'face of the key slot let in the coupler overlics the depressed or eut away portions 13 therein. The additional bearing areas formed on the proj ections 11 constitute continuations of the key bearing portions' of the slotted side walls in the yoke head, each additional bearing area being arranged in alinement with the key bearing portion as now provided at the forward ends of thekey slot in each yoke arm. y

Having thus described my invention, what I claimas new and desire to secure by Letters Patent, is:

1. In a railway draft rigging, the combination with center sills, of a coupler having depressions in opposite sides thereof, a yoke, a key connecting the yoke to said coupler, and means on said yoke adapted to provide relatively large and increased bearing areas for said key, said means projecting inwardly of the yoke arms and capable of moving into the depressions formed on the coupler.

2. In a railway draft rigging, the combination with car sills, of a coupler having depressions in opposite sides thereof, and a slot intersecting said depressions, a hooded yoke having opposite side walls each of which is provided with an opening, a key extending through said openings and slot for connecting the yoke and coupler, the side walls of the hooded yoke being formed with inwardly extending reinforcing portions adjacent at least one end of the openings therein, said inwardly extending portions providing relatively large hearing areas for the forward edge of the key and capable of moving respectively into the depressions in the coupler upon angling movement thereof.

In a railway draft rigging, the combination with carsills, of a coupler having an opening, a yoke having a hooded end, the opposite side walls of which are slotted, means passing through said slotted walls and opening into the coupler for connecting the latter to the yoke, and means formed on said yoke adapted to provide an increased bearing area for the means connecting the coupler and yoke, said last named means being adapted to coact with adjacent portions (of the coupler for permitting angling of the latter while providing for said increased bearing area.

4. In a railway draft rigging, the combination with center sills, of a coupler having an opening, said coupler having opposite sides thereof formed with cut-away portions adjacent said opening, a yoke comprising spaced arms having the forward ends thereof slotted, a key passing through said slotted forward ends and the opening in the coupler, said forward ends of the yoke arms having portions adjacent said slot adapted to form increased bearing areas for the key connecting the coupler and yoke, said portions being adapted to coact with the cutaway portions on said coupler.

In a railway draft rigging, the combination with center sills, a yoke member comprising spaced arms each having a slot at its forward end, projections formed on said yoke arms and extending inwardly thereof, said projections providing relatively large key bearing areas, a coupler insertible between said yoke arms and projections, said coupler having opposite faces provided with cut-away vportions adapted to coact with said projections and being provided with an opening disposed in alinement with the slots in the yoke arms, and a key connecting said yoke and coupler, said key having portions contacting said relatively large bearing areas on said projections.

6. In a railway draft rigging, the combination with car sills, of a yoke member having spaced arms, each of said arms being slotted at its forward end, a reinforcing projection formed on each yoke arm and e3;- tending inwardly thereof adjacent the slot in said arm, a coupler insertible between said projections, said coupler having cutaway portions coacting with said projections and being formed with an opening, and means connecting said coupler and yoke, said means passing through the opening in the coupler and slots in the yoke arms and having a bearing on said reinforcing projection. i

7. The combination with a slotted yoke. of a coupler provided with an opening and having opposite side portions adjacent said opening cut-away at points opposite the forward ends of the slotted portions of said yoke to permit angling with respect to said yoke, and means passing through said opening for connecting said coupler and yoke.

8. The combination with a yoke member comprising slotted arms, of a coupler provided With a shank having an opening, said shank being provided upon opposite sides thereof with depressions located adjacent the forwards ends of said opening to provide Clearance between the shank and yoke, and a key connecting said coupler and yoke.

S). A yoke for railway draft rigging coinprising a hooded end having outwardly flaring side walls each formed with a slot, and reinforcing projections disposed adjacent the forward ends of said slots and extending inwardly of the side walls, said projections having keybearing areas disposed in aline nient with the key bearing portions of said slots.

10. A hooded vertical yoke for railway draft rigging having outwardly flaring oppositely disposed slotted side walls, each of said side walls being provided with an inwardly extending projection forming a key bearing area disposed in alinernent with the key bearing portion of the slot orrned in each wall.
