CARL LEHNERT, or M'A-RSELCH, AND HUBERT HuLsENBusoH, or

wALsUM, GERMANY,

RAILWAY-COUPLING.

Specification of Letters Patent.

7 To all whom it may concern Be it known that we, CARL LEHNERT, a resident of Marselch, and HUBERT Hi'JLsEN-, BUsoH, a resident of Walsum, Germany, subj ects of the German Emperor, have invented new and useful Improvements in Railway+ Couplings, of whichthe following is a specification; I

This invention'relates to a coupling for railwaycars, the engagement of which is automatically efleoted when two cars. abut against each other, while the disengagement can be done by hand from the side of the car.

The accompanying drawings show in Figure 1 in side view, and in Fig. 2 in plan, the new railway-coupling as attached to the ends ofthecar.

The longitudinal rod (1 is supported in the base-frame of the car at b and c in such a manner that it can move in its axial direction.

At the rear end projecting beyond the supporting-point b the rod (1 carries a coil-spring d, intervening between the support I) and the collar 6, in which the rod a terminates at this end.

I At the front end projecting beyond the sup porting-point c the rod a carries the fixed coupling member f, which is forked and has aninclined abutting plane and a round inner surface. 1

Near the front end the rod a is provided with a movable coupling member 9, the head of which is shaped round.

Below the base-frame of the car a transverse shaft h is movably mounted and provided with a fixed projecting rod i. The latter is at its free end pivotally connected to a linkk, the free end of which is in turn pivotglly connected to the movable coupling memer g. The free ends of the transverse'shaft h projecting at the sides of the car are provided with a fixed reversing-lever l, which is counterweighted in order to balance the movable coupling member 9 when the latter is in its disengaged position. Of course each end of the car must be provided with the coupling, as abovedescribed.

The operation of the coupling isas followsz movable coupling member of one car runs up the incline of the fixed coupling member of the other car and is then caught behind the forked end of the latter. The cars are again uncoupled by simply reversing the lever l of the transverse shaft h from the side of the car,

whereby the movable coupling member 9 is lifted out of the fixed coupling member 7: through the medium of the lever system 'i I Patented Nov. 6, 1906.

and is then held in this lifted-up position by v the counterweight of the reversing-lever Z.

By forming the head of the movable coupling member, as well as the inner surface of the fixed coupling member, round the former is allowed of having a certain play in the latter, so that the coupling is efficiently prevented from breaking even when the train runs over sharp curves. Having fully. described our invention, what we claim, and desire .to secure by Letters Patent, is I A coupling for each end of a railway-car, comprising in combination, a longitudinal rod a supported in the base-frame of the car so as to be capable of axial movement; a coilspring (1 placed around the rear end projecting beyond the inner support of said rod a, a collar 6 fixed to the inner end of said rod a and destined to keep said coil-spring din place a rigid coupling member f fixed to the front end projecting beyond the outer support of said rod a and provided with a forked end, an inclined abutting plane and a round inner surface; a movable coupling member g pivoted to the front end of said rod aand provided with a round head and adapted to catch with the latter behind the forked end of said fixed coupling member f of the other-car; a transverse shaft h movably mounted below the base-frame of the car a fixed projecting rod i provided on said shaft h; a link is pivoted with one end to the free end of said projecting rod 4 andwith the other endto said movable coupling member g," and a counterweighted reversing-lever I provided at each free end projecting at the sides of the ear, of i set our hands in the presence of two subscribsaid shaft h and adapted to lift said movable ing Witnesses. coupling member 9 out of said fixed coupling CARL LEHNERT. member f of the other car and to hold it in HUBERT HULSENBUSCH. 5 this lifted-up position, substantially as de- Witnesses:
