ANDREIV DRENGSON, OF THOMPSON, (DAKOTA TERRITORY,) NORTH DAKOTA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 415,449, dated November 19, 1889.

Application filed April 19, 1889. Serial No. 307,726. (No model.)

To all whom it may concern:

Be it known that 1, ANDREW DRENGSON, of Thompson, in the county of Grand Forks and Territory of Dakota, have invented a new and Improved Automatic CarCoupler, of which the following is a full, clear, and exact descrip tion.

This invention relates to car-couplers, the object of the invention being to provide a coupler which will couple automatically and which may be manipulated without entering the space between the ends of the cars, whereby all danger of the crushing of the trainhands is avoided and the coupling of the cars constituting a train is easily brought about.

To the end named the invention consists, essentially, of a draw-head in which there is pivotally mounted a coupling-hook, said drawhead being provided with an open recess adapted to receive the (oupling-hook of a corresponding coupler, and a hook-raising device arranged within the draw-head, all as will be hereinafter more fully explained, and specifically pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective View of a portion of a car, representing the same as it appears when provided with my improved coupler. Fig. 2 is a longitudinal sectional view of two couplers constructed in accordance with the terms of my invention, the parts being represented as they appear when in the coupled position, and Fig. 3 is a cross-sectional view on line a: m of Fig. 2.

In the drawings, 10 reprcsentsa draw-head formed with a recess 11, which extends through the upper wall of the draw-head. Through this recess there is passed a transverse pin 12, which bears against a face 13,

formed as shown in Fig. 2, the pin 12 serving as a wear-pin, against which the couplinghook of the opposing coupler bears. The op- In the lower portion of the draw-head is mounted a block 17, which is connected to an upwardly-extendin g stem 18, to which stem there is connected a chain 19, that extends to a vertical shaft 20, having a hand-wheel 21, said hand-wheel being located in proper position to be operated from the tops of the cars; or the wheel might be located in any other convenient position. In passing from the stem 18 to the shaft 20 the chain 19 runs upon a sheave 22, that is supported by a standart 27, said standard being secured to the draw-head.

Such being the general construction of my improved coupler, it will be seen that as two cars provided with such couplers approach, the coupling-hooks, which are formed with inclined faces a, will strike against the flaring mouths Z) of the opposing draw-heads and will ride up over said flaring months I), over the pins 12, to the position in which the parts are shown in Fig. 2, the hooks engaging the pins 12 of the opposing draw-heads, as will be readily understood.

To uncouple the cars, the shaft 20 is turned and the block 17 is raised, which movement of the block will throw the coupling-hooks from engagement with their pins 1.2.

\Vith such a coupler as the one above described all the cars of a train may be coupled by simply bringing them together, and to uncouple the cars there is no necessity of the train-hands entering the space between the cars.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t In a car-coupler, the combination, with a draw-head formed with recesses 11 and 13, of a coupling-hook pivotally mounted within the recess 13, a transverse block which extends beneath the coupling-hook and into the recesses 11 and 13, a stem extending upward from the block, a chain connected to the stem, and a shaft upon which the chain is wound, substantially as described.

ANDREW DRENGSON.
