JOHN DAVID STOVALL AND WILLIAM CALVIN WHITTINGTON, OF CADDO
MILLS, TEXAS.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 370,499, dated September 27, 1887.
Application filed April 25, 1887. Serial No. 1236,07. (No model.)To all whom it mazcy conce7fl:
Be it known that we, Jon DAVID STOVALL
and WILLIA3t CALVIN WITITTINGTON, citizens
of the United States, residing at Caddo Mills,
5 in the county of Hunt and State of Texas, have
invented a new and useful Improvement in
Car-Couplings, of which the following is a
specification.
Our invention relates to improvements in
ro car-couplings; and it consists in a certain novel
construction and arrangement of parts for serv-
ice, fully set forth hereinafter and claimed.
The object of the invention is to provide a
reliable and durable coupling which will be
J5 disposed on the under side of the car-body
and adapted to coupleautomatically and to be
uncoupled very readily by a person at the side
of the car.
In the drawings hereto annexed, Figure 1 is
20 a bottom plan view of two cars connected by
our improved coupling. Fig. 2 is a similar
view in the uncoupled position. Fig. 3 is a
detail section longitudinally through the un-
coupling-latch.
25 Referring to the drawings by letter, A desig-
nates the coupling-link, having a hook on the
front end beveled on the front side, the said
link being pivoted at the rear end to the under
side of the car-bottom, and having the shoul-
30 der a to limit the forward motion of the op-
posing link.
B designates a lever approximately parallel
with the said link, pivoted near the central
point to the under side of the car a short dis-
35 stance from the said link, the front end of the
lever being connected to the link near the for-
ward end by the spring C, which is adapted
to normally hold the said link pressed away
from the lever. To the rear end of the said
40 lever is pivoted the end of a bar, D, adapted
to slide in a way, E, disposed transversely of
the car; and G is a latch pivoted on the lower
side of the saidbar D, and having a rod or pin,
TI, to pass through the perforation d in the
45 said bar and engage in a socket or opening, h,
in the bottom of the car, or in a plate secured
thereon. The said socket is so disposed that
when the pin is engaged therein the lever D
will be in the position shown in Fig. 1, and to
5o hold the said leverin that position we provide
a spring, 1', under the outer end of the latch tohold the inner end thereof depressed and the
pin in the said socket.
K represents a retractile spring secured at
one end to the bottom of the car and at the 55
other end to the front end of the lever 3, the
function of the same being to draw the said
.front end of the lever laterally and cause the
link A to be drawn outof engagement with the
link of the opposing car. 6o
L represents a lever disposed approximately
parallel with the side of the car, and pivoted
at one end to the outer end of the bar D, and
pivoted near the center to the under side of
the car-body. 65
The operation of the invention is as follows:
When it is desired to arrange the coupler to
form a connection with the link of an oppos-
ing car, draw the rear end of the lever B lat-
erally, by means of the lever L, until the pin 70
on the latch enters the socket in the bottom of
the car by the action of the spring under the
outer end thereof. When the opposing links
impinge, they will be forced laterally against
the power of the springs C, and the hooked 75
ends thereof will engage, as seen in Fig. 1.
When it is desired to uncouple the cars, press
the outer end of the latch G against the force
of the spring, thus drawing the pin -I out of
the socket h, and the retractile spring K will 80o
draw the front end of the lever laterally and
release the coupling-links from engagement.
The operation of the device is very simple,
and the means employed are strong, reliable,
and are not apt to need repair. 85
The coupler is disposed under the car, and
therefore entirely out of the way, the only pro-
jection being the end of the coupling-link.
The operation of uncoupling is very simple,
it being only necessary to press the handle of 90
the latch, and the remainder of the action is
automatic; also, when the cars are uncoupled,
the free end of the bar L projects out laterally
from the side of the car, and to arrange the
link in the coupling position it is simply nec- 95
essary to press the said free end in until the
latch causes the pin on the inner end thereof
to engage in the socket formed on the under
side of the car therefor.
Having described our invention, we claim-- oo
1. In a-car-coupling, the combination of the
link A, pivoted on the under side of the car
