ALLAN TAWLKS,. OF HARVEY, NO-TH DAKOTA, ASSIGNOR OF ONE-HALF TO IRA D. CLARK, OF HARVEY, NORTH DAKOTA.

CAR-COUPLING.

fo all whom 'honey concern.'

ie it known that I. ALLAN `.-\wmis, a citizen of the United States,V residing at liarvey. in the county of Tells and State of North Dakota. have invented a new and useful Car-Coupling, of which the following' is a specification.'

The invention relates to improvements in car couplings.

They object of the present invention is to improve the construction of car couplings, and to provide simple. inexpensive and e'iicient means for connecting the draw bar of a car coupling with the draft rigging, whereby the car coupling may be quickly removed and replaced, so that cars will not be delayed in transit. when breakage of a ear coupling or draft spring or other''iortion of the draft rigging.

ldlith these and other objects in view, the

invention consists in the construction andv novel combinz-tion of parts hereinafter fully described, illustrated inthe accompanying drawing, and pointed out in the claim hereto appended; it being understood that varions changes in the form.7 proportion, size and minor details of construction, within the scope of the claim, may be resort-ed to 'without departing from the spirit or sacri-l ficing;- any of the advantages ofthe inventionA 'ln the drawingtnigure l. is a side elevation of car coupling, constructed in accordance with this invention. Fig. 2 is a plan view of the saine. Fig. 3 is a detail sectional view illustrating the construction for detachabiy connectingthe draw bar with the draft. yoke. Fig. 4t is ay transverse sectional View on the lines i-4 of Fig. l. Fig. 5 is a detail perspective view of the draft yoke. Fin'. 'ti is ay similar view of the r-ear portion of the draw bar.

form engaging;- portions, and the rear lugs 4f of the draw bar 1 have their front transverse edges 10 correspondingly beveled or inclined to form grooves or Ways in which the lugs of the draft yoke are interlocked when the parts are assembled. The outer transv rse faces 1l of the lugs 6 of the draft yoke are vertical, and the rear transverse edges or faces 1,2 of the front or outer lugs 3 of the draw bar l are also vertical to fit the end faces or edgesll of the draft yoke.

The draw bar is' engaged with and disengaged .from the draft yoke by rotating it a quarter of a revolution to carry'the front and rear lugs 3 and 4 from the sides of the draw bar 'to the top and vice versa. 'The draw` bar vis introduced between the spaced lugs ,6 of the draft yoke with the front and rear lugs 3 and i at opposite sides of it. the space between the lugs (i being sufficient for this purpose. TWhen the grooves 5 are brought opposite the lugs 6, the draw bar is rotated one quarter of a revolution to swing the front and rear lugs 3 and 4- into engageinent with the lugs 6. This partial. turning of the draw bar on its longitudinal axis carries the front and rear lugs 3 and 4 to their normal position at the top and bottoni of the draw bar, and they are disengaged from the lugs G by rotating the draw bar backward one quarter of a revolution to arrange them at opposite sides of the draw bar. This manner of interlocking the draw bar andthe draft yoke enables the former to be `quickly connet'ztwl with and disconnected from the draft yoke. and a car couplingmay be readily removed from a car in the event 'of the breakage of any of theparts of the draft riggino. and it may be quickly replaced without causing any material delay of a car when the same in transit. lhis is especially advantageous when handling fast frebjht or perishable goods, and it obviates the inconvenience and trouble of cut-ting a CII car out from the center of a train when the draft rigging becomes defective.

In order to enable the draw bar to be par- The bottoms of the grooves 5 and-the lugs' 1+i present transverse convexly curved bearing faces, and the lugs 6 are provided with inner concavely curved bearing faces 15 to fit the bearing` faces 14: of the grooves 5, and the upper and lower sides or portions of the yokes have transverse recesses 16, presenting concave faces to iitthe rear lugs 3. These bearing faces permit the car coupling to be rotated to connect its draw bar with and disconnect it from the draft yoke.

The car couplingis held against rotary movement by means of a. vertical key 17, tapered from the top to the bottom to form a wedge-shaped engaging member and extending through recesses 1S and 19 of the yoke and the front lugs 3 of the draw bar and through a slot 2O of the latter. 'lhe slots or bifurcations 1S extend through the ends of the upper and lower sides of the yoke from the outer faces of the sides to the inner bearing faces preferably hollow, as shown, and the slot extends vertically through the rear portion of the draw bar and connects the recesses 19. :Phe tapering wedge shaped key ei'igages ooth the draw bar .bar and eftcctually prevented from spreading. The lugs may be made of a size to per- `what I claim as new and 1:3 of the lugs G. The draw bar is and the draft yoke, and it is adapted to take up the wear and it pre- 'bar and the ingl the lower end of the key and engagingv the lower side or portion of the yoke at opposite sides of the recess 18 thereof. When it is desired to detach the car coupling, the

pin is removed and the key is detached. lhiswill permit the partial rotary Inovenient necessary to disengage the lugs of ther draw bar from those of the draft yoke.

Havingr thus fully described lnyinvention,`V

desire to secure by Letters Patent, is l The combination of a draft formingr intervening grooves to receivethe lugs of the yoke, the rear lugs having inclined faces to interlock With the inclinedl rear faces of the lugs of the draft yoke and the front lugs being provided with recesses arranged in alinement with the bifurcations of the yoke, and a tapering key arranged in the recesses of the front .lugs and the bifur cations of the yoke and passed through the y draw bar and presenting inclined faces to the parts at the front of the dovetailed lugs.
