WILHELM GRAUPNER, OF JARMEN, GERMANY.
CAR-COUPLING..
SPECIFICATION formingpart of Letters Patent N o. 720,687, dated February 17, 1903.
Application filed September 4, 1902. Serial No. 122,056. (No model.)
To all whom it may concern:
Beit known that I, WILHELM GRAUPNER, master smith, a subject of the Emperor of Germany, and a resident ofJarmen, Prussia, German Empire, have invented a new and useful Car- Coupling, of which the following is a specification.
My invention relates to car-couplings, and particularly to couplings which are to be 0perat-ed from the platform of the car.
The invention is illustrated in the accompanying sheet of drawings, in which- Figure 1 shows the coupling closed in side elevation, the opened position being shown in dotted lines. Fig. 2 is a cross-section of the draw-head as illustrated in Fig. 1.
In the construction of a car-coupling according to my invention I use a draw-head g, formed like a pair of tongs, the one leg of which is firmly secured to the car-frame a by .means of an singularly-shaped upward extension, which extension at its upper end carries a screw-threaded bearing b for a vertical screw-spindle d. This latter is operated by a crank c and has its lower end linked to the free leg f of the tongs-like draw-head, so as to operate the bit of the said tongs. This latter consists of the upper hook-shaped jaw h, 0f the usual construction, having its forward end obliquely shaped, and of the lower jaw 1l, which has itsgripping end beveled on both sides. The surface k, which acts against the upper hook h, fits snugly against the beveled end of said hook when the draw-head is closed, as shown in Fig. 1. TheV upper hookshaped jaw h of the tongs is provided with two fiat downward extensions Z on each side, which extensions grip over the jaw i" on both sides of the oblique surface k, as clearly shown in Fig. 2. l
The operation of the coupling is as follows: When the cars are brought together with the coupling open, the draw-bar m enters with its eye the bit of the draw-head, so as to rest on the oblique surface lo. By now closing the coupling by means of the screw-spindle d and crank c the eye m of the draw-bar is forced down ythe surface 7c by the cooperative action of the extensions Z and the said surface, and finally the hook h grips into the eye m, thus securing the coupling in the position shown in full lines in Fig. 1.
Having now particularly described Iny invention, I kclaim-- In a carcoupling, the combination of a draw-head in form of a pair of tongs, a screwspindle mounted against the platform of the car and adapted for operating said draw-head, a screw-threaded bearing for said spindle, an oblique surface on the lower jaw of the bit of said draw-head and downward extensions at the upper jaw which on both sides grip over the said oblique surface for forcing a drawbar to be received within the bit downward behind the coupling-hook, substantially as described.
