SPECIFICATION rforming part of Letters Patent No. 286,992, dated October 23, 1883.

' Application inea July so, issu. (No moda.)

To all whom it may concern: p

Be it known that I, ROBERT BIGNEY, engineer, a subject of the Queen of Great Britain, and a resident of Copleston, in the county of Lambton, in the Province of Ontario, Canada, have invented a new and useful Improvement on Self Oar Couplers, of which thev following is a specication.

This improvement relates to the invention for which Letters Patent were issued to me the 17th day of April1883, No. 275,880; and it consists of the improved construction and combination of parts of the same, 'which will be hereinafter more fully described and claimed.

Reference being had to the accompanying drawings, Figure 1 is a perspective viewof part of a car, showing a perspective view of my improvement. Fig. 2 is an end elevation of same; and Fig. 3 is a-view of the draw-bar, partly in section.

A -designates an` L-shaped upright lever passing through a slot, in the bracket C,`

which bracket O is rigidly secured to the ear B2. This L-shaped uprightleverA is provided with handles A A2 and stud B, and is pivoted on a pivot-bolt, x', secured in and near one j end of the lever E.

D is a spring secured -to the bracket C, between the bracket C and lever A, which spring D firmly holds the L-shaped upright lever A in pl ace, preventing said leverA from shaking `loose when set to couple or uncouple the ears.

This slot x in the bracket C is long enough to allow the lever A and stud B to pass through it together when required.

E is a lever provided with handle E and fulcrumed on pivot-bolt mi', supported in a bracket, e, rigidly secured to the car B2, and projecting out from this lever E atone side are the fingers e2 which clasp the coupling-pin F.

F is a coupling-pin, on the upper end of which a screw-thread is formed, with which a pin F, which regulates the distance the coupling-pin F enters the pinhole F2 of the draw,- bar K when coupling the draw-bars K K of the ears together, and this collar G, with the upper part of guide H, regulates the distance that the coupling-'pin F is to be raised when uncoupling.

J- is a spring-bolt, which is projected longitudinally in the draW-barK by the spring J p J 2 is a key which projects through the bolt J. The ends of this key J2 move back and forth in the slots K in the sides of the drawbar K, which allows spring J to project the bolt J out only sufficient to bring flange J3 under the lower end of the coupling-pin F.

Then the coupling-pin F is in the position shown in Fig. 3 of annexed drawings in both draw-bars K K, the cars are coupled. To uncouple the cars instantly, press down on the handle A' irst, which compresses the spring D and brings the st ud B over the slot w in the bracket C, then press down on both of the handles A and E', which raises the inner end of the lever E, with the fingers e2 and the coupling-pin F free from the link T, and allows the cars to separate. At the Sametime as the coupling-pin F is raised the lever A is loweredand the stud B is brought below the bracket C, and as soon as the handle A is released from pressure the spring D moves the stud B over under the solid portion of the bracket Gand holds it there and prevents the lever A from ris ing. As the cars B2 B2 separate and the coup ling-link T is drawn out from the draw-bar K the bolt J is projected outward by the spring J until the fiange J3 comes under the lower end of the eouplingpin F, the distance the bolt J is projected outward being regulated by the length ofthe slot K in the draw-bar K, in which the ends of the key J 2 move back and forth. adjusted as shown in Fig. 3, were to strike against the drawsbar in which the coupler is adjusted, as shown in Fig. 2 of annexed drawlf the draw-bar K, with the coupler( ings, they would part again without, coupling, y

IOO

To adjust the cars to couple instantly when .2 ascesa one of them is adj usted as shown in Fig. 3 to one adjusted as shown in Fig. 2 'of annexed drawings, press down on the handle A until the stud B is brought opposite the slot :v inthe bracket C, which compresses the spring D, then raise both handles A and E, which lowers the inner end of the lever E with the fingers e2 on the guide H, las shown in Fig. l of anneXed drawings, the coupling-pin F being still retained in its position by the ilange J i ofthe bolt J. At the same time as the inner end of lever E, with fingers e2, is lowered the lever A is raised and the stud B is raised through the slot a: in the bracket C, and as soon as the handle A is released from pressure the spring D moves the stud B over on the solid portion of the bracket C, as shown in Fig. 1 of annexed drawings, and prevents the lever A from lowering.

If a draw-bar, K, with the coupler adjusted as shown in Fig. 8, were to strike the draw-bar with the coupler adjusted as shown in Fig. l of annexed drawings, the coupling-link T would force the bolt J back and release the couplingpin F from the iiauge J 3, and the coupling-pin by its own weight would instantly shoot down through the link T and couple the cars together.

'The handle AL is for the purpose of adjusting the coupler to unconple or couple the oars 33 from the top of the ear.

Having thus described my invention, l clainii The combination of the L-shaped lever A, provided with stud B,'bracket C, provided 35 with slot x, spring D, lever E, provided with ngers e2 e2, bracket e, coupling-pin F, provided with collar G, nut F', guide H, drawbar K, provided with slots K', spring J bolt J, provided with flange J3, and key J2, oon- 4o structed substantially as shown and described, and for the purpose specified.

In testimony whereof I afx my signature in the presence of the two undersigned witnesses.

l ROBERT BIGNEY.
