Improvements in and relating to Car Couplers.
I, JAMES HENRY SCOGGIN, a citizen of the United States of America, residing
at 233 Porterville Street, in the City of Petersburg, County of Dinwiddie and
State of Virginia, one of the United States of America, Farmer, 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 :-
The special object of the invention is to make a car coupling which will couple
automatically, uncouple easily by lifting the cover of the draw-head, and be little
liable to get out of order.
Reference being made to the accompanying drawings, in which
Figure 1 of the drawings is a longitudinal vertical section of two draw-heads
connected by my coupler.
Figure 2 is a longitudinal horizontal section, and
Figure 3 a detail perspective view of my solid link with a pin pivoted to each
end.
In the drawing A represents my link provided at each end with a coupling pin B,
pivoted at or near the middle on a cross pin C, between the prongs 6 b. The rear
arm of the pin B is supported on the link-shelf a as the link advances into an
opposite draw-head.
D is the draw-head which has a rigidly attached vertical abutment d, and a
cover D¹ hinged at d. The sides of the draw-head are rebated at D2 to support
the lift-rod G, which is held across the cover in the staples F, F, made fast
thereon. d represent spaces in which turn the prongs e² e² of the cover D¹.
As the link A advances into a draw-head with its front pin horizontal, the front
end of the pin which is beveled on the upper part thereof, strikes the abutment d
and is turned down, thus causing the rear arm to rise, lift the cover D', pass beyond
it and allow the cover to fall in the rear thereof, as clearly shown in Figure 1 of
the drawing.
In order to uncouple, it is only necessary to raise the rod G with the cover D',
when the link and pin will escape from one of the draw-heads.
It will be readily seen that the link and pins being attached together, neither is
so liable to be lost or out of place; that the brakeman is never in danger in coupling
or uncoupling the cars, that the coupling is automatic and certain, and that the link
has the easy lateral play so necessary.
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. A car coupling link provided with a coupling pin at each end, the said pins
being pivoted between prongs thereof at or near the middle, beveled at each end on
the same side, and adapted to rest with one end in a groove of the link, as shown
and described.
2. The combination with a link having a pin pivoted at or near the middle of
one end, of the abutment as B on the base, and a draw-head as C having the front-
pivoted cover c², arms c³ ³ and rebates c c, whereby two draw-heads may be coupled
and uncoupled, as described.
