` WILHELM SCI'IURR, OF CANNSTAT'I, NEAR STUTTGART, GERMANY.

CAR-COUPLING.

Speeieaton of Letters Patent.

Patented Oct. 22, 1907.

Application filed February 2,1907. Serial No; 355,475.

To all whom it may concern:

Be it known that VI, WILHELM SCHURR, a subject of the Emperor of Germany, residing at Cannstatt near Stuttgart, Wrtemberg, Germany, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare th e 'following to be a ull, clear, and exact description oi the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

illy invention relates to a railway car coupling, which locks automatically when two ears come together, and

which may be unlocked from the sides of the cars by a pull or by pressure.

My coupling consists principally in the combination of an actuating member in the form oi a hinged loop and a locking member in the form of a pair of hinged arms normally held in a distended position and one oi which carries a freely swinging locking bar. I provide means located between said arms adapted to be operated by said actuating loop member to draw said hinged arms toward one another and to thrust said freely swing ing locking bar through said looped member and the opposite hinged member to securely hold the cars together.

The accompanying drawing shows my invention in Figures l to ll, of which Fig. l is an elevation partly in section o the device in a coupled position; Fig. 2 is a plan view partly in section o the same; Fig. 3 is an elevation partly in section of the hinged arm locking member in the distended or unlocked position; Fig. 4 is an elevation of the saine in the closed position; Fig. 5 is a plan View of the same; Fig. 6 is a longitudinal section through a portion of the locking member and showing the latch mechanism operated by a chain; Fig. 7 is a transverse section ot same; Fig. 8 is apart sectional view of a modi iisd form showing the latch operated by pressure on a foot piece; Fig. 9 is a plan view of same; Fig. l0 is a plan view of the hinged loop actuating member; and Fig. Il is a side view osaine and broken away.

Referring to the iigurcs, A and A represent the loop actuating members hinged at the ends E, E, to the car through eyes F, by means oi" the bolts G, G. Loop members A., Af, are also provided at their ends with stops II, II, adapted to limit the swing ofthe same.

The locking member comprises the arms L, IJ, hinged at N to the sleeve IC. Sleeve K is mounted on the extremity of the draw bar .l oi the car.

M is the free swinging locking bar hinged at B to the arms l'/ and adapted to lie behind the transverse bar C when in the closed position.

O is the trip bar slidably mounted in the sleeve K between hinged arms L, L, and provided with trip arms Q, Q, hinged at the outer end thereof. The trip arms Q, Q, are pivotally connected at their other ends intermediate oi the hinged arms L, L, whereby when said trip bar O is forced inward from the pressure of the opposing loop member A, the hinged arms L, L, will be drawn toward one another.

P is a spring operating within the sleeve K between the end oi the draw bar J and the trip bar O and operating to force said trip bar outward.

The trip bar O is provided with a recess O/ into which a latch pin R is adapted to be projected by means Oi a spring IV. Latch pin R is mounted through a sup'- porting 'frame R2 and through an opening in the Wall of the sleeve K.

As shown in Figs. 6 and 7 the latch pin R is pulled out to release trip bar O by means of a chain D running to the side ofthe car as shown in Fig. 2, but I may with equal effectiveness provide the operating means shown in Figs. 8 and 9, in which the lever S is loosely mounted at one end through a slot in the shank of the latch pin R and is rigidly mounted on the shaft V at its other end.4 A foot lever 'l is mounted on shaft U at the side of the car, and said shaft will be oscillated by a pressure thereon to pull the latch pin out as will be readily seen.

Having thus described my invention, what I claim l. ln a car coupling, the combination with a locking member comprising` a body portion and hinged arms connected to the body portion and normally held in a distended position, of a tripping mechanism mounted within said locking member and pivotally connected to said hinged arms, and means for actuating said tripping mechanism to draw said hinged arms toward one another, substantially as described.

2. In a car coupling, the combination with'a locking member comprising a hollow body portion mounted on the draw bar, hinged arms extending from said body portion and normally held in a distended position, of a trip bar mounted in the hollow of said body portion, pivotal connections arranged between said bar and said hing'cdarms whereby, when said trip bar is pushed inward, said hinged arms will be drawn together, one of said hinged arms being provided with a transverse bar and a locking bar carried by the other of said arms and adapted to lay behind said transverse bar when in the locked position, substantially as described.

3. In a car coupling, the combination with a locking member comprising a hollow body portion, hinged arms extending from said body portion and normally held in a distended position, of a trip bar mounted in the hollow of said body portion, trip arms connecting said bar to said hinged arms, said bar beine; adapted to be pressed inward to draw said hinged arms together and being provided with a recess therein, and a latch mechanism mounted through the wall of said body portion and adapted to e11- gage within said recess when said trip bar is pushed inward, substantially as described.

4. In a ear coupling, the combination with a locking member comprising a hollow body portion, hinged arms extending from said body portion and normally held in a distended position, of a trip bar mounted in the hollow of said body portion, trip arms connecting' said bar to said hinged arms, said bar being adapted to be pressed i11- ward to draw said hinged arms together, and being provided with a recess therein, a spring pressed latch mounted through the wall of said hollow body portion and adapted to engage within said recess when said trip bar is pulled inward, and means whereby said latch may be 1 released from the side of the car, substantially as described.

In testimony whereof, I ax my signature, in presence of two witnesses.
