THOMAS MOK. STUART, OF OOUNCIL BLFFS, IOWA.

CAR-COUPLING.

SPECIFICATION forming' part of Letters Patent No. 505,930, dated October 3, 1893.

Application filed September 6, 1892. Serial No. 445,210. (No model.)

To all whom it may ooncern:

Be it known that I, THOMAS MOK. STUART, a citizen of the United States, residing in the county of Pottawattamie, State of Iowa, have invented a new and useful Car-Coupler, of which the following is a specification.

My improvement has for its purpose the adaptation of link and pin couplers to a'utomatic couplin'g with couplers of the Vertical plane ort'win jaws type. This is accomplished by means of a supplemental or movable T- shaped head, conformed at one end to the shape and dimensions of the link cavity in the link and pin coupler, and at Ithe other end to the 'swinging jaw and recess in the head of .Vertical plane couplers in ordinary use; said supplemental head to be carried by cars having link and pin couplers, for use when occasion requires.

Figure 1. represents the supplemental head in adjustment upon a car provided with link and pin coupler. Fig. 2.represents a car provided with a coupler of the Vertical plane type. Fig. 3. represents supplemental head detached. Fig. 4. is a sectional View of the supplemental head inserted within a link and pin coupling.

In Fig.1.A is the supplemental head in position, held securely by being at the rear end conformed to the shape and size of the link cavity of the link and pin coupler with which it is to be used.V G is the pin which passes Vertically down through the coupler and supplemental head and secures it in position.

Fig. 2. represents a car provided with a Vertical plane coupler of the master car builders7 type., B is the recess in the forward end of the same. C is the swinging jaw of the same, and D is the link holding slot or bifurcation, ordinarily provided for coupling with link and pin couplers.

Fig. 3. represents supplemental T-shaped head detached, being but a general Outline of its form, the form being necessarily divergent, as it is made in each case to conform to the diverse forms and shapes of link cavities which it is securely held by the pin of the link and pin coupler.

My device is designed to operate in the followingmanner, to wit: Each car provided with a link and pin coupler shall also be provided with two supplemental heads conformed in Shape and dimensions to the link cavity of its drawbars. When the occasion requires a coupling with a Vertical plane coupler, the supplemental head shall be inserted into its place in the link cavity and secured by the pin, the jaw of the opposing drawbar then thrown open when the ordinary impact of the cars will close the' jaw upon the Vertical flanges of the supplemental head, the bifurcated opening or linkslot inthe jaw at the same time embracing the transverse horizontal arm of the same, thereby effecting a coupling without exposure to the operator.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A detachable, supplementallhead, constructed with a Vertical, T-shaped flange or inflexible head, which is conformed in form and dimensions to the recess in the head 'of Vertical plane couplers of the J anney type.

2. A detachable, supplemental head, having a transverse horizontal arm, made of such Shape and dimensions as to readily pass `between and be embraced by the bifnrcated jaws of Vertical plane couplers of the J anney Itype.
