CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 423,152, dated March 11, 1890..
Application filed January 11, 1890. Serial No. 836,705. (No model.)
To all whom it may concern.-
Be it known that I, GEORGE F. HARLAN, of Leeds, in the county of Cecil and State of Maryland, have invented a new and useful Improvement in Car-Couplings, of which the following is a specification.
My invention is an improvement in carcouplings; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.
In the drawings, Figure 1 is a perspective side view of a car with my coupling attached. Fig. 2 is a horizontal sectional view of two draw-heads with the pin in coupled position, 1and Fig. 3 is a side elevation of the couplinga1 The draw-head A may in general form be of ordinary construction, having the flaring mouth a, leading to its throat or mortise B, and provided with suitable openings 0 for the coupling-pin O. I make the draw-head with the end or head portion A and the shank or draw-bar portion A in rear thereof, slots A being formed through the rear wall of the head A for the passage of the springplates 1) 1). Now, while these springs may be secured to the draw-head in any suitable manner, I prefer to extend them through the slots A secure their rear ends to the shank or draw-bar A against which they are lapped, and have their front portions arranged on opposite sides of the pin 0, and arranged to spring outward at such ends to admit the shouldered or arrow head of the coupling bar, and then in to hold such bar in engagement with the pin 0. It will be seen that the draw-heads are alike, the'coupling bar being secured at one end by the pin of one draw-head and having its opposite end formed with an arrow-head e to enter the meeting draw-head and be held in engagement with the pin thereof by the spring-plates. Now it will be seen that my coupling presents a construction in which the side springs form bearings for the arrow-head and guide the same into engagement with an intermediate securing device and hold the head in such engagement.
While I prefer the double form. of arrow head shown, it is manifest that a single shouldered arrow head might be employed without departing from some of the broad principles of my invention. In such con struction the drawhead of course need have but one spring-plate and have a suitable guide construction to properly direct the sin gle shoulder of the couplingbar into engagement with the pin or other fastening device It will be noticed that the arrow-head is tapered upward on its under side to its point.
In securing the coupling-bar in the draw head which supports it I provide such coupling-bar with an opening E which receives the couplingpin, and such opening E is widened at its forward end, so as to permit the bar to play laterally on its securing pin, so that the coupling-bar cannot by any possi bilitybe so tightened in the draw-heads as to bind against the coupling-pin engaged by its head, so as to prevent the lifting of the said pin to detach the coupling.
It is obvious that in case it is desired to couple to an ordinary draw-head the improved draw-heads are adapted to receive and secure the ordinary link.
Having thus described my invention, What I claim as new is= 1. In a car-coupling, the draw-head pro vided with guide openings for the coupling pin and provided on opposite sides of such guide-openings with spring-plates by which to direct the arrow-head into engagement with the coupling-pin held in such guides, all substantially as set forth.
2. In a carcoupling, the draw head having the head or front portion and the shank or draw-bar portion in rear of such head and having slots or openings in the rear walls of such head portions and the spring-plates eX- tended through the said slots and secured at their rear ends to the sides of the draw-bar portion, substantially as set forth.
8. In a oar-coupling, a coupling-bar having an arrow-head at one end and having at its opposite end an opening for the securing-pin, such opening being widened at its front end, substantially as set forth.
4. The improved car-coupling consisting of the draw-head having a coupling-pin. ar-
