ADAM SYLVESTER NEAL, OF RICHMOND, TEXAS.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 359,092, dated March 8, 1887.
Application filed September 1, 1886. Serial No. 212,373. (No model.)To all zwhon, it 7nay concern:
Be it known that I, ADAM SYLVESTER NEAL,
of Richmond, in the county of Fort Bend and
State of Texas, have invented a new and use-
5 ful Improvement in Car-Couplers, which im-
provement is fully set forth in the following
specification and accompanying drawings.
The special objects of this invention are to
provide an automatic device for coupling cars,
to which will allow for the different height of
cars when loaded and empty, and to so con-
struct the parts that they can be operated from
the tops and sides of the cars by suitable means,
so that the operator is out of danger of being
15 injured; also, to arrange the prehensile parts
in such a manner that it will couple auto-
matically when the cars are run together.
In the drawings, Figure 1 is a perspective
view of part of the end of a freight-car, to-
20 gether with my improvement. Fig. 2 is atop
view of the frame to which the principal parts
of the coupling are attached.
A and B are heavy jaws of wrought metal,
each having two hooks, F F'and G G', formed
25 on the outside and inside of the end, as shown
by the drawings. These jaws are attached to
the beam D in such a manner that they can
have motion laterally, and are held together
by a spiral or other spring, I, attached at or
30 near the middle of their length, as shown in
Fig. 2. At the ends J J', which project be-
yond the beam D, are spiral springs j, for the
purpose of taking up all longitudinal motion
and hold them tight against the shoulders,
35 which are provided at K K'. A buffer, C, lo-
cated between the jaws, is also attached to the
beam D, and is provided with the usual
spring, L.
The apparatus for operating the jaws A and
4o B is shown in Fig. 1. Near the center of the
timber M is journaled a perpendicular shaft,
N, which extends to the top of the car, and is
provided with a wheel (not shown) for oper-
ating it. To this shaft, or a suitable enlarge-
45 ment, 0, ofit, are attached chains V, which move
laterally to and around the grooved pulleys 0'
O',near the corners of the car,thence to the jaws
A and B,to which they are attached. The trans-
verse shaft P is attached to the car by suitablebearings at T T', and it is provided with levers o50
R R at the ends, which can be operated at the
side. To the rollers Q Q' are attached chains
which pass up around the grooved pulleys 0'
0', thence down to the jaws A B.
The levers at the side of the car are for op- 55
crating the jaws A B from the ground. The
chains, which are attached to the shaft P, are
arranged so as to wind on the pulley or un-
wind by shortening or lengthening the chains
by a right or left movement of the levers R. 6o
The chains, being attached to the jaws A B,
will cause an outward lateral movement when-
ever the chains are shortened, and an in-
ward movement by the action of the spring I
whenever the chains are lengthened. Theper- 65
pendicular shaft, being connected to the jaws
in a similar manner,will causeasimilar move-
ment of the jaws whenever it is rotated by the
wheel at the top of the car.
This coupling is operated bypartially open- 70
ing the jaws A B by means of the levers at
the side of the wheel at the top of the car, so
that the closed jaws of the car with which it
comes in collision will, on account of the bev-
eled front ends, insinuate themselves between 75
the opened jawg, and pass in far enough for
the outer jaws to close laterally, engaging the
hooks, and thus couple automatically, as
shown in Fig. 2. It will be seen that the cars
can be uncoupled whenever desired by a move- 80o
meant of the side levers, or by means of the ro-
tation of the perpendicular shaft N at the top
of the car.
What I claim as my invention is-
1. In a car-coupler, the jaws A and B, each 85
having two side hooks, F G, combined with
the bar D, and springs j and F' G', when ar-
ranged to operate laterally andsimultaneously
for the purpose of coupling and uncoupling
cars, substantially as described. 90
2. In combination with the jaws A and B,
which are arranged to move laterally and si-
multaneously, the levers R R', shaft P, pul-
leys 0' O', and the chains which pass over the
pulleys 0' 0' and connect the rollers Q' Q' 95
with the jaws A B, when used for the purpose
substantially as herein described and set forth.
3. In combination with the jaws A B, the
