SPECIFICATION forming partl of Letters Patent No. 502,711, dated August 8, 1893. Application sled February 8,1893. semi No. 461,487. (No model.)
To all whom, it may concern:
Be it-known that I, JOHNFISCHER, a citiaenL of the United States, residing at Scottdale,in the county of lVestmoreland and` State of Pennsylvania, have invented a new anduseful Car-Coupling, of which the following isa specification.
The invention relates to improvements in car couplings.
The object of the present invention isto simplifyandimprove the construction of twiny jaw car couplings, and to provide anv auto-v matic one which will not necessitate goingv between cars in coupling and uncoupling, and twhich will be positive and reliable in opera.-
ion.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended.
In the drawings-Figure lis a perspective view of a car coupling constructed in accordance with this invention. Fig. 2 is a vertical longitudinal sectional view.
Like numerals of reference indicate corre- .sponding parts in both the'tigures of the draw- 1ngs.
l designates a hollow cylindrical draw-bar having detachably secured to its front end by' a coupling pin 2 a twin-jaw coupler-head 3, which is approximately vertically disposed, and which consists of similar oppositely disposed upper and lower hooks 4 adapted to, en.- gage similar hooks of atwin draw-head. The draw-head 3 is provided with a central opening 5 to receive the front end of the draw-bar, and it is provided with a coupling-pin perforation 6 which receives the coupling pin 2. The coupling pin 2 passes throughacoupling pin perforation of the draw-bar, and enables a link 7 to be employed for coupling with the ordinary construction of pin and link car couplings, and also in event of the breakage of the twin-jaw draw-head. When the link is not in use it may be stored in the hollow or` tubular draw-bar ready for use. The drawhead isheld in proper position for coupling by a spiral spring 8, which .is disposed on the 5o inner portion of the draw-bar and is secured thereto and is also connected with the car.
position. to permit thelever to be slightly elevated The spring does Vnot interfere with the useof the ordinary draw-spring', and maintains the hooks 4; in positive engagement with the hooks of a similar draw-head. The uncoupling ,is performed by a lever 9 having its inner end attached to the draw-head, audits outer end terminating at one side of the car; the lever is arranged` in a keeper depending from lthe car;vand the keeperL l0 servesas a stop to limit the movement of the draw-head by the spring to maintainthe `draw-head in proper The keeper 10 is ot' sucient length from its lowerY end when cars are coupled, to enable the draw-heads tohave sufficient play without the lever striking againstl'the lower end of the keeper.
lVhen it is desired to hold the draw-head uncoupled the leveris brought by raisinginto engagement with a projection l1 of the car.
It will be seen that the car coupling is simple and effective in operation, and that it is adapted to'couple withthe ordinary pin and link coupling besides its coupling with a twin draw-head. v n
Changes in lthe form, proportion and the minor details of construction may beresorted to without departing from the principle or sacricing anyA of the advantages of` this invention.. Y
The hollow outer portion of the draw-bar forms a link cavity, and the coupling pin is 'heldagainst accidentalV disengagement by a key. The projection or stop 1l formsacatch for the leverbut other forms of catches may be employed.
l. In a car coupling, the combination of a rotary tubular draw-bar adapted for the storage of coupling links and provided at its front end with transversely-aligned perforations, a twin jaw draw-head provided with a central opening itted upon the draw-bar and having perforations which register with those in;v the draw-bar, a coupling-pinengaging said registering perforations and also adapted for the engagement of a coupling-link, and a torsional actuating spring operatively connected to the draw-bar to hold the draw-head in its engaging position, substantially as speciled.
2. In a car-coupling, the combination of a IOC rotary draw-bar provided withatorsional actuating spring, a twin jaw draw-head having a central opening which is fitted upon the front of said draw-bar, and a coupling-pin engaging registering perforations in the drawhead and draw-bar, whereby the former is fixed to the latter for rotation therewith and is detachable therefrom upon the disengagement of said coupling pin, substantially as specified.
3. In a oar-coupling, the combination of a rotary draw-bar, a draw-head fixed to the front end of the draw-bar, an actuating spring conneeted to the draw-harto hold the draw-head normally in its operative position, an uncoupling lever fixed at one end to the draw-head whereby the latter may be rotated against the tension of said spring, and a fixed keeper in which the free end of the lever swings, and which serves to limit the rotation of the drawhead when not in engagement with an opposing draw-head, substantially as specified.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses..
J OI-IN FISCHER.
