Improved Couplings for Railway Vehicles.
1 JOHN LOUIS SHOENBERGER subject of the German Empire & Cityzen to the
Granducy of Hessen Darmstadt but at present residing in Pittsburgh state of
Pensylvania United States of America do hereby declare the nature of this invention
to be as follows:-
In Coupling Railway Vehicles a detachcable bar, with spring comptrolled hooks,
pivoted in chambers therein, to perform automatic action and couple to one of two
cars in the same manner. A hollow drawbar provided with a slot at its floor, for the
end of hook to ingage in, thereby holding the cars togetter. This drawbar is
secured to the lower surface by brackets, having in its arm bearing for journal of the
shaft of draw bar proper the rear end of same is fixed to a cross piece of timber
on car.

I JOHN LOUIS SHOENBERGER now of 168 43rd Street, Lowrenzville, Pittsburg
United States of America, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
This invention relates to a coupling device for cars which will couple automatically
on the cars coming together, but requires to be uncoupled by hand; and will be best
understood by reference to the accompanying drawings.
Figuro a sectional sido elevation.
Figure 2 a sectional perspective view.
A, A', is a compound hollow draw bar attached to underside of each end of a car.
Each drawbar consists of two parts A and A' the former being hinged at A* to
underside of car and the latter to A' at A. The hinge A admits of lateral movement
and the joint A of vertical movement of the part A'. These movements combined
with the trumpet shaped mouth of A' facilitates coupling. The parts A and A' are
held in their normal position by springs B and F; the former acting upon a plate O,
upon which the part A' rests. The extent of the lateral movement of the parts A
and A' is controlled by the brackets D and E. Pivotted to A' is a hook G, held down
by a spring H; the outside of fang of hook is made inclined as shown at I. J is the
coupling bolt pointed at each end to act on the incline I, of hook G, to raise it.
The bolt J is formed with two openings or slots J₁ for the hook G to enter and lock
the bolt in A' and effect the coupling; one end of the slots J₁ being made inclined
corresponding to the inside of fang of hook. The inside end of slot J' is pressed
against the inside of fang of hook by a piston K, held by a spring K. L is a
locking stop which when in the position shown in drawing prevents the hook being
lifted to free the hook the stop L, is moved on its fulcrum L' by, for example, a
crank L² to uncouple; the pivot M of hook G may be sufficiently extended (not shown
in drawing) to come outside of car and have a crank handle or wheel attached to
enable hook G to be lifted to free bolt J, the hook G being first relieved of stop L, or
a double crank arrangement one crank in advance of the other, could be arranged to
both lift stop L and hook G, one after the other, by turning the same outside handle.
Having now particularly described and ascertained the nature of this Invention and
in what manner the same is to be performed, I declare that what I claim is:
The combination of parts forming a car coupler, with or without the stop I,
constructed and operating, substantially as hereinbefore described and represented in
the accompanying drawings.
