CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 336,950, dated March 2, 1886.

Application filed April 27, 1885.

To aZZ whom it may concern.-

Be it known that we, FRANcoIs ELZIAR ROUSSEAU and HENRY BUELL GoonA LE, both residing at Au Sable, losco county, Michigan, and MIsAiiL COTE, residing at Oscoda, Iosco county, Michigan, citizens ofthe United Stat-es, have invented new and useful Improvements in Car-Couplings; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The object and nature of our invention are such that the same will couple automatically when two cars to which they are attached,havinga commonlink in the draw-head of either, are driven together, and which may be ancoupled from either or both sides or from the top of the car, and which may also be set by means of a crank so as not to couple when so desired, thus entirely removing the prime cause of danger to life and limb attendant upon the operation of coupling and uncoupling cars in the ordinary manner.

The invention consists in the peculiar construction, combination, and arrangement of the several parts, as is more fully described hereinafter.

Figure 1 is a vertical section of our carcoupling with the crank removed. Fig. 2 is a side view of our car-coupling, showing the mechanical construction and workings of the same when coupling. Fig. 3 isatop view of our car-coupling when coupled. Fig. 4 is a reverse view of the cap or plate 0, and showing its lower portion, 0, and the groove or opening D therein.

Like letters refer to like parts in each of the figures.

A, in the annexed drawings, represents our draw-head,having a balloon-shaped chamber, B, which permits of the free action of the insorted end of the link, either upward, downward, or sidewise, according to the position or elevation of the draw-heads on the cars connected, and also having a sufficient opening from the top downward through for the reception of the lower portion of cap 0, as 0, and the pin H,pendent therefrom. The shoulders thus formed by this opening, and which Serial No. 163,6 '2. (No model.)

are designated by b and b, are used as bearingpoints for the pin H when in actual use after coupling.

The cap 0 is aplate, which forms a complete covering for the main portion of the draw-head A,thereby protecting the mechanical workings of our car-coupling from storms of snow and sleet. On the under side of said cap is a projection or lower portion, 0, which is secured at its rear end to the draw-head A by means of the bolt F. On this bolt as a pivot the front portion of said cap may be readily raised in the operation of coupling and uncoupling. The rear end of said cap is so formed that the cap will not pass up and back ward only sufticientl y responding hole in the draw-head A, by which operation the said coupling is securely fastened in position so as not to couple, which is often very desirable in shunting cars about the yard. By sliding the crank in a reverse manner the said pin L is withdrawn from the draw-head A, and the said cap falls back into proper position to couple. Said crank Jis an ordinary crank passing through the cap 0 at G, and extending backward along either side ofthe drawhead A until nearly even with the platform of 5 the car to which the draw-head is attached, then outward until nearly even with either side of the car, and then'turningat each end and forming a handle. WVhen the cap 0 is in position for coupling,its lower portion, 0, projectsinto 9 the opening in the top of the draw-head A sufficiently so that after a link is driven into the said draw-head the inserted end will come in contact with the said lower portion of cap 0 from above, and the link will be held horizontally and in proper position to enteran opposite draw-head. On the top of said cap is an eyebolt, e, to which a wire rope or chain may be attached for the purpose of uncoupling from the top of the car.

In the front end of-Ioo the lower portion of cap 0 is an opening or groove, D, in and from which a slightlycurvcd pin, H, is suspended by means of the bolt K, so that whenever the said capis raised the pin H is drawn upward perpendicularly, and when the said cap falls back toits position for coupling the said pin H enters the draw-- head perpendicularly. At the upper end of said pin H is an oblong hole orslot, I, through which bolt K passes in suspending thesaid pin from the cap 0. When in position for coupling, the said pin so suspended hangs free to move at the slightest touch. On the entry of a link into the draw-head A said link will force the said pin H slightly backwarthwhcn the lower portion of the same comesin contact with the lower portion of the cap 0. Then, owing to the peculiar shape of thecap Oat the place of contact, the pin H changes its movement and shoves or slides upward on bolt K,by means of the said slot I, until about two-thirds of the pin H hasentered the opening orgroove D in the cap 0. Then,to allow said link to pass through under the remaining portion of pin H, the cap (3 readily rises. W hen the inserted end of the link has thus passed the pin H, the said pin drops back into its original perpendicular position, and the cap 0 falls back into its position on the draw-head A simultaneous1y,and the coupling is made. The combination, conjunction, and perfect arrangement of these several motions of the said pin H and cap 0 in the operation ofcou pling and unconpling allows of the use of as short a link with our coupling as may be used with a common draw-head and straight pin, and also forms a simple, complete, and perfect automatic coupling. When the link is drawn against the pin H when in use after coupling, the said slot I allows the said pin H to bear directly against the said shoulders b and b in the draw-head A, thereby entirely relieving the bolt K and cap 0 from any and all stress and strain while in use.

M represents a common link.

The draw-head A is secured to the car in a manner similar to an ordinary drawhead.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-- In a car-coupling, the draw-head provided with openings and slots, as described, in combination with the hinged cap having a lower,

downward extension, a, slotted pin H, and operating crank J, all the parts being constructed and arranged for joint operation substantially as specified.

In testimony that we claim the foregoing as our own we afiix our signatures hereto properly witnessed.
