JOHN s. MGGRAW, or RICHMOND, IXDIANA.
@ CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 272,294, dated February 13, 1863.
Application filed December 1,1882. (No model.)
10 all whom it may concern:
' Be it known that I, JOHN S. MCGRAW, a citizen of the United States, residing at Richmond, in the county ofVV-ayne and State of Indiana, have invented certain new and useful Improvements in Oar-Couplings; andIdo declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a partof this specification.
My invention relates to car-couplings, and has for its object the construction of a car- 'coupling that can be easily coupled and uncoupled; that will, when the cars are jammed together, connect one car with the other automatically, without the dangerous necessity of a person standing between the carsto holdup 1 same.
A is an ordinary draw-head, formed with angular aperture or opening a entirely through crosswise of the draw-head, and a short distance in rear of its outer end, on opposite sides, in a horizontal plane, is formed alongitudinal slot for the reception of long flat springs c '0.
Fitted to move loosely inside the aperture a are two clamping-jaws, b b. each of said jaws is secured one end of along metal spring, 0, the opposite end of which is To the back of b b is beveled out or cut away on its inner face to conform to the inner face of the drawhead A and to receive the link. At the inner base of the bevels. rearward, the'clampingjaws -b b have parallel sides .formed to hold the link (J.
In rear of the clamping-jaws b b a concave recess, 1, is formed in the draw-head A, to receive the end of link 0 when pushed inward in the act of coupling. Bv this construction a concavity extends from the outer face of the draw-head A inward to the bottom of recess i.
On top of the draw-head A is formed a circular cone-shaped elevation, f, perforated and having two flat walls to receive the pin B. The perforation in the part fextenjs down into the aperture a, and from the aperture down through the lower half of the cross-head A. Through this perforation the pin B passes when the link 0 passes into the recess 6. The pin B is formed with two flat sides and with collar or shoulder on its outer end, said shoulder terminating in a perforated bail, to which a cord or chain may be attached for the purpose of operating the pin from the top orv sides of the car. The lower end of this pin is formed with a projection or spline, 9, that is formed to pass through a slot inthe lower perforation of the draw-head, and it also forms a stop when it reaches the perforation in partf by withdrawing the pin B.
An ordinary car-coupling link, 0, is used with my improved draw-head.
The operation of my device is as follows: When it is desired to couple two or more cars having my improved coupler, the pin B is drawn up until the projection g strikes against the under side of the partf, when the edges of thejaws b b will be bronghtin contact'with each other and form a bearing on which the inner end of the pin B rests, being in position as shown in Figs. 3 and 4. The opposite car to foration below, thereby holding the link and securely coupling ,the cars.
groove in said draw-head, the jaws b and b, 15 formed and operated as described, and the adjust-able clamp-band D, all arranged and op erated substantially as shown and specified.
2. The combination of the draw-head A, springs c and 0, band D, and link 0, with the pin B, havingspline g, and perforated conef. all arranged substantially as shown and specified. In testimony whereof I atfix my signature in presence of two witnesses.
JOHN S. MGGRAW.
