Year: 1884

page_text: I WILLIAM HENRY HOLT of 267 Queens Road Halifax in the county of York
Cooper do hereby declare the nature of my Invention for "IMPROVEMENTS IN
to be as
UNCOUPLING RAILWAY TRUCKS,"
APPARATUS FOR COUPLING AND
follows:-
The object of my invention is to construct a simple and efficient apparatus for
coupling and uncoupling railway trucks, from outside the line of rails, and
preventing the numerous accidents which now occur.
In the sides of the lower link of the coupling links, I attach two studs, connected
to the studs is a fork lever, each side of the fork being connected to the link stud,
the other end or spindle of the fork is carried in a bush or cylinder upon the
spindle of the fork is a spiral spring which lifts up the fork sufficient to keep the
lower link in an horizontal position the bush or fork cylinder is connected to a rod
on the front of the body of the truck, this rod has a handle or arm, which when
uncoupled hangs in a vertical position, on raising the arm the links are raised, and
placed mechanically over the hook of the draw bar, on the truck to be coupled, and
is dropped on to it, and thereby coupled, on uncoupling, the fork lifts the links
clear, and then lowers them down to the hanging position, when the trucks are on
a curve, by having bosses on the rod carrying the bush for fork spindle, the links
can be drawn either way, so as to drop on the hook in whatever position they may
be, a cast iron pin is used for securing the fork in its bush or holder, so that should
at any time the draw bar break no further damage will occur than the breakage of
the cast iron pin.
The handle so as not to be in the way may be made to swivel or hang down.

page_text: I WILLIAM HENRY HOLT of 267 Queens Road Halifax. in the county of York
Cooper do hereby declare the nature of my said Invention for "IMPROVEMENTS IN
APPARATUS FOR COUPLING AND UNCOUPLING RAILWAY TRUCKS," and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
The object of my invention is to construct a simple and efficient apparatus for
coupling and uncoupling railway trucks from outside the line of rails without the
attendant going between the trucks thus preventing the numerous accidents which
now occur.
In the side of the lower link which is preferably heart shaped of the coupling
links, I attach two studs, connected to the studs is a fork lever, each side of the
fork, being connected to the link studs, the other end, or spindle of the fork is
carried in a bush or cylinder; upon the spindle of the fork is a spiral spring which
lifts up the fork sufficient to keep the lower link in a horizontal piston, the bush or
fork cylinder is connected to a rod on the front of the body of the truck, this rod
has a handle or arm, which when uncoupled hangs in an almost horizontal position;
on lowering the arm, the links are raised and placed mechanically over the hook of
the draw bar on the truck to be coupled, and are dropped on to it, and thereby
coupled; on uncoupling, the fork lifts the links clear, and then lowers them down
to the hanging position; when the trucks are on a curve by having bosses on the
rod carrying the bush for fork spindle, the links can be drawn either way, so as to
drop on the hook in whatever position they may be; a cast iron pin is used for
securing the fork in its bush or holder so that should at any time, the draw bar
break, no further damage will occur than breaking of the cast iron pin.
The handle so as not to be in the way may be made to swivel or hang down, or

page_text: link ensures it engaging with the hook; the pin L, for securing the fork and
spring in its bush or holder, may be made of cast iron or cast steel so that should
at any time the draw bar break, no further damage will occur than the breaking
of the pin.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is;-
1 The use and employment of links, such as A, with studs or pivots B, for the
purposes shewn and described.
2 The combination of the shaft H, arms F, and fork lever C, operated by levers,
wheels or other suitable means, for the purposes as shewn and described.
Dated this fourth day of November 1884.
