PROVISIONAL SPECIFICATION.
An Improved Car Coupling.
I, WILLIAM WILSON HORN of the firm of Horn and Son of 151 Strand
in the County of Middlesex Patent Agent do hereby declare the nature of this
invention (a communication to me from Adrian Testard of Gonzales State of
Texas United States of America Inventor) to be as follows :-
The special object of my invention is to make a car coupler in which the link
shall cause the pin to drop within it & which can be coupled or uncoupled from
the side or top of the cars without danger to the brakeman & which is provided
with means for lifting the links of cars with lower draw heads.
The draw head in my said invention is constructed with the usual top bottom &
sides and the registering holes for the pin.
The cross wall is partially open for the catch bar, the said catch bar being formed
with a shoulder, which is held in place by its own weight..
The upper end of said catch bar is pivotted to a lever fulcrummed upon a pillar
or bracket on the top of the draw head.
The said lever is connected at its opposite end to the link pin, & this last men-
tioned end is also connected by a link with an arrangement of levers by means of
which the link pin may be raised when required.
When the pin is raised as just described the catch bar retains it in position until
the opposite or
engaging link enters the draw head and its end strikes the catch:
bar when the pin is caused to fall by its own weight.
In order to support the link in a horizontal position a device consisting of two
parallel bars with a connecting bar between them, the said device being capable of.
moving in and out of the draw head by the action of a rack and pinion, the latter
being operated or rotated by means of a suitable handle from the side of the car.
The said link supporting device is constructed and arranged so that the link is
brought in a line with the mouth of the opposite draw head.
Dated this 16th day of December 1890.

COMPLETE SPECIFICATION.
An Improved Car Coupling.
I, WILLIAM WILSON HORN, of the firm of Horn & Son, of 151 Strand,
London, in the County of Middlesex, Patent Agent, do hereby declare the nature
of this invention, (a communication to me from abroad, by Adrian Testard of
Gonzales State of Texas United States of America, Inventor) and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :--
The special object of my invention is to make a car-coupling in which the link
shall cause the pin to drop within it, which can be coupled or uncoupled from the
side or top of cars without danger to the brakesmen, and which is provided with
means for lifting the links of cars with lower draw-heads.
Figure 1 is a plan and Figure 2 a side view partly in section.
In the drawings A represents the draw-head, with the usual top and bottom a a'
and the usual registering-holes a a³ for the pin B.
P is the cross-wall open at p for the catch bar D whose shoulder d is held in
place by its own weight, the bar D is pivotted at the upper end to a lever C

page_text: fulcrumed at E in the top of the draw-head A. The lever C is pivotted to the
pin B at point N, also to the connecting rod S at the same point. The connecting
rod S is attached at M to the lever G.
Thus by a forward movement of the lever G as represented in dotted lines in
Figure 2, the pin B is raised to its proper height and the catch bar D holds it in
position until the link enters the draw-head A and its end strikes the bar D
knocking it from under the point and the pin falls to its place by its own weight.
G is a lever fulcrumed at to the side of the car but it may be attached to the top
of.box-cars.
J is a link support which moves back and forth or out and in the draw-head A.
by means of the rack & pinion i, and lever shaft the latter being operated by a
lever H on either side of the car. The shank of the link support J consists of two
parallel bars.J one on each side connected to a face plate O and faced underneath
to slide on the subjacent flat spring K.
The shank J is concaved on the upper side so that when it is moved out by the
rack and pinion, the spring K will lift the link support so as to bring the link in
its own draw-head on a line with the mouth of the opposite draw-head. In this
way draw-heads of unequal heights may be very readily coupled without raising
the link by hand.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:―
1. In car couplers, a draw-head having cross wall P, open at pin combination
with a hanging catch-bar D having the shoulder d, connecting link S, pivoted
lever C, and a lever G for raising the link and a coupling pin, the whole con-
structed and operating substantially as described and illustrated.
2. A link support) concaved on top and provided with the rack / in combina-
tion with the flat subincent springs K. the minion; and lever shaft. 2 onerated by
