UNITED STATES PATENT OFFICE
ADRIAN NUTTING, OF GREENVILLE, TEXAS.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 355,657, dated January 4,1887.
Application filed July 8, 1886. Serial No. 207,465. (No model.)To a7Zl whom, it may concern:
Be it known that I, ADRIAN NUTTING, a citi-
zen of the United States, residing at Greenville,
in the county of Hunt and State of Texas, have
5 invented new and useful Improvements in Car-
Couplings, of which the following is a specifi-
cation.
This invention has for its object to provide
simple and novel means for coupling cars by
1o means of a hook and the ordinary link, with-
out the necessity of the brakeman entering be-
tween the car-platforms. This object I ac-
complish in the manner and by the construc-
tion and combination of devices hereinafter
15 described and claimed, reference being made
to the accompanying drawing, in which the
figure is a side elevation of a portion of a car,
showing my improved coupling devices ap-
plied thereto.
20 In order to enable those skilled in the art to
make and use my invention, I will now de-
scribe the same in detail, referring to the
drawing, where-
The numeral 1 indicates a draw-head con-
25 .nected with the car in any suitable manner,
and provided with a vertical central slot, in
which can rise and fall a hook, 2, pivoted at
its rear end in the draw-head, as shown at 3.
The ordinary coupling-link, 4, is adapted to
30 engage the hook, and to operate the latter I
provide the following simple mechanism: A
transverse shaft, 5, is journaled in suitable
bearings at the end of the car, and terminates
at one or both ends in a crank-handle, 6. The
35 shaft need only extend from the center of the
end of the car to one side thereof, and at its
inner end is rigidly attached a crank-arm, 7,
having at its outer end a curved head, 8, the
face of which is furnished with a cu rved groove
40 to receive and guide the chain 9. Thehead 8,.
at its upper end, is provided with a lateral
lug, 10, to which is secured the upper end of
the chain 9, the lower end of the latter being
connected with the pivoted vertically-swing-
45 ing hook, and to said lug is also secured a rod,wire rope, or chain, 11, extending to the roof
of the car.. The shaft 5 is provided with a
toothed or ratchet disk, 12, to be engaged by
a pivoted pawl, 13, mounted on a suitable
support, 14. 50
If a link enters the draw-head, it will strike
the inclined face of the hook, lift the latter,
and pass fhereunder, when the hook, by grayv-
I ity,will fall into engagement with the link. If
it is desired to uncouple the cars, the handle 55
6 is swung to rock the shalt 5, and thereby
raise the crank-arm 7, thus drawingthe chain
and lifting the hook to disengage it from the
link. In this movement the grooved curved
face of the head 8 of the crank-arm 7 guides 60
the chain. The crank-arm can be operated
from the roof of the car by the rod 11, as will
be obvious, and when the coupling-hook is ele-
vated it may be held in that position by en-
gaging the pawl 13 with the toothed or ratchet 65
disk 12, thereby locking the shaft 5 in posi-
tion to prevent its rocking in such direction
as would lower the hook.
The construction and operation of the de-
vices are simple and efficient, and permit the 70
coupling-hook to be conveniently raised or
lowered from the side or from the top of the
car.
Having thus described my invention, what I
claim is- 75
The combination, with a draw-head and a
swinging coupling-hook pivoted therein, of
the rock-shaft having the crank-arm 7, pro-
vided with the grooved head 8, the chain ar-
ranged in said groove and connected with the 8o
hook, the ratchet-disk on the shaft, and the
pawl for engaging the ratchet-disk, substan-
tially as described.
In testimony whereof Iaffix my signature in
presence of two witnesses.
