CAR-COUPLING.
srEcmIcATIoN forming part of Letters Patent No. 523,564, dated July 24., 1894.
Application filed March 10, 189 4.
' exact description of said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.
My invention relates to car coupling of the J anney type, and has particular. reference to that kind in-which there is employed a hook-nose provided with a lever-arm having an inclined surface at its end adapted to act on an inclined surface of the locking device.
Heretofore, such a coupler has been employed in which the locking device is a verticallymovable pin, but with such coupler, considerable force is necessary to raise the pin to permit the end of the lever-arm to pass behind it.
The object of my invention is'to provide a construction by means of which. a comparativelylight pressure will be sufficient to move the locking device, and a further object is to provide a locking bearing of the greatest pos-. sible extent.
To these ends, my invention consists in the construction and combination of parts as hereinafter described and pointed out in the claims.
In the accompanying drawings,Figure 1 is a plan view of my improved coupler. Fig. 2 is a section on line 2,2 of Fig. 1, showing the lever-arm as displacing the locking-plate. Fig. 3 is a similar section, showing the leverarm as locked by the plate. Fig. t isa section on line 4:-''4:, of Fig. 2. Fig. 5 is a detail of modification hereinafter described.
Similar reference letters indicate the same parts in the several views.
The drawhead A is represented as of the usual form of this type of coupler, and having the hook-nose a pivoted in the head at a. The rearwardly-extending arm a of the hooknose constitutes the lever-arm, and its end is rounded or convexed in a vertical plane, as shown in Figs. 2 and 3, and also beveled or rounded off laterallyand rearwardly, as shown in Fi .4, the object of this particular shape Serial No. 503,153- (No model.)
of the end of the lever-arm being hereinafter explained.
The locking-plate B is loosely fitted in a I may be provided for the reception of a pin to keep the plate swung aside when it is desired to prevent automatic action of the coupler.
Instead of depending on the shoulderbfor the fulcrum of the locking-plate, I may pivot the said plate to the drawhead, asby a pin extending through a hole in the shoulder and into lugs of the drawhead, as indicated in the detail view Fig. 5. A hole?) in the lower end of the plate receives a pin to prevent the plate from becoming accidentally removed from its slot in the drawhead.
The edge of the plate B is concaved, as at b on the arc of a circle having substantially the same radius as the vertical convexity of the lever-arm, and it will thus be seen that a more extended bearing of the two parts against each other is afforded than if the end of the lever-arm andthe co-acting portion. of the plate were straight.
When two cars are brought together and the hook-noses turn on their pivots in the usual manner, each lever-arm comes in contact with its locking plate, andowing to-the location of the fulcrum of the latter the contact of the two parts first occurs at one end oral swing of the locking plate permits a much easier movement and operation than when a pin or bar has to be bodily lifted, and also, that the locking plate presents a broad and strong support against unlocking the coupler.
Having now described my invention, what I claim is 1. In a car coupling, the combination with the hook having a vertical pivot and a rearwardly-extending arm provided with a beveled end, of the locking plate loosely fitted in a slot of the drawhead, and having the shoulder b resting on the top of the drawhead and v. having a pointed tip entering a recess in the top of said drawhead substantially as de scribed.
