[Communicated from abroad by DANIEL JOSEPH HARDING, JOHN STRANGE CAIN,
ROY M"DONALD, and PAUL CAIN, all of Louisville, in the County of Jefferson,
and State of Kentucky, one of the United States of America, Gentlemen.]
I PETER JENSEN of 77 Chancery Lane, in the County of Middlesex, Fellow of
the Institute of Patent Agents do hereby declare the nature of the said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
Figure, 1, of the drawings is a representation of my improved car-coupling
applied.
Figure, 2, is a front view of the same.
Figure, 3, is a bottom view.
Figure, 4, is a longitudinal vertical sectional view.
This invention relates to car couplings; and it consists in the construction and
novel combination of parts as hereinafter set forth.
Referring by letter to the accompanying drawings, A, designates a box-car, the trucks
and body being of the well-known constructions now commonly used on railroads in
the United States.
B, designates one of the draw-heads which is provided with aligned pin holes, C, D,
in its upper and lower walls, respectively, for the reception of the ordinary coupling
pin, E, which latter is provided with an eye, F, in its head, and is connected by a
chain, G, to a pin, H, on the pulley, I, fixed to the transverse crank rod, J, supported
in bearings, K, K, projecting from the end of the car body at a proper and convenient
height from the ground.
In rear of the pin-holes, C, D, and preferably back of the rear wall of the mouth of
the drawhead, I provide a pin-hole, K' which passes vertically entirely through the
draw-head.
Passing vertically down through the pin-hole, K', is a headed lifting rod, L, the
lower end of which rod, L, is split or recessed to fit over the lifting lever, M, near
the front end of the latter. The head of the lifting rod, L, is connected by a chain, N,

page_text: which passes up along the rear of the pulley, I, and has its upper end secured to the
front of the pulley, I, by the same pin, H, that secures the chain, G, (which may be
a continuation of the chain, N) to the pulley, I. The lower end of the chain, G, is
connected to an eye in the head of the coupling pin, E. In the lower wall of the
draw head near the front edge of the said lower wall, I, provide a pin hole, S, through
which the stem, T, of the lifter plate, U, in the mouth of the draw-head passes. The
stem, T, is passed down through pin-hole, S, and its lower end is connected to the
front end of the lifting lever, M, the rear end of said lifting lever, M, being fulcrumed
or hinged between bearings on the lower face of the draw bar, V, which is supported
in the usual manner between the timbers under the car body. The hole for the
fulcrum pin in the rear end of the lever M is oblong or slotted to allow for the free
vertical working of the rods Land T. The crank arms at the ends of the crank rod, J,
depend normally that is, when the coupling pin is in its seat said arms project
downwardly.
By turning either of the cranks of the rod, J, upwardly and toward the front, or in
the direction away from the end of the car body, the coupling pin, E, will be lifted or
raised in its seat to permit the introduction or withdrawal of the coupling link. When
the coupling link is in place and it is desired to couple with another car on which the
draw-head is higher than the one in which the link is held, by turning the depending
crank backward or toward the body of the car the lifter-plate, U, will be raised in the
mouth of the draw head and will carry the link up with it, so that the projecting end
of the link may readily enter the mouth of the opposing draw head.
The lifter plate, when down or lowered, resis in a recess or depression in the lower
wall of the draw head, so that it cannot be struck by a link when entering the mouth
of the draw-head.
In applying the improvement to draw-heads already constructed it is only necessary
to provide the additional pin-holes herein used in front and rear of the ordinary
coupling pin holes.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The combination, with the draw-bar and the draw head provided with the
coupling pin hole, the aligned pin holes in rear thereof, and the pin hole in the lower
wall near the mouth of the draw-head, of the lifting lever, the lifter plate connected
by its stem to the lifting lever, the coupling pin the lifting rod, the crank rod
provided with the pulley, and the chains connecting the coupling pin and lifting rod
to said pulley, substantially as specified.
2. A draw head having a longitudinal lifting lever slotted at its rear end and there
pivoted to the rear of said draw head, said lever carrying at its front end a pivoted
vertical lifter stem extending through an aperture in the front of the drawhead floor,
and having middle connection with the transverse operating crank rod, substantially
as specified.
