THOMAS FREDERICK REMER, 44 West Derby St. Liverpool in the County of
Lancaster Contractor's Clerk do hereby declare the nature of my invention for
AN IMPROVED RAILWAY COUPLING ARRANGEMENT to be as follows:-
My invention relates to an improved method of coupling railway cars and other
vehicles by which the danger to the railway employés is considerably reduced.
My invention consists as follows.
In the centre of the ends of the ears or other vehicles-I provide a single volute
coil spring buffer, either with or without a cylinder to receive it, at the end of the
spindle which guides and passes through the centre of the volute, I provide a jaw-into
which the head, of the opposite volute coil spindle of another car, fits. The jaw is so
arranged as to allow for the lateral movement of the car.
The jaw of one buffer and the corresponding head of the other, are both slotted, so
that when they are brought into contact with each other the slots which are vertical,
come over each other.
Into these slots I drop a vertical drop bar which thus fixes the head and jaw and
couples the cars together.
The mechanical arrangement by which I lower this drop bar is as follows, at each
side of end of the car I provide a wheel handle working in a vertical plane, side by
side with the car fixed in an easily and safely accessible position, This wheel handle
actuates by bevel gearing a shaft, on which is a spur wheel placed in the centre of the
end of the cars, and directly opposite to the drop bar, this spur wheel works into a
toothed bar, so that by turning the wheel handle this toothed har is lowered or raised,
the upper end is provided with a hollow projecting arm in which there works a coil
spring at one end of which is suspended the drop bar-so that on lowering or raising
the toothed bar by revolving the wheel handle it simultaneously lowers the drop bar,
into the slots of the buffers.
The coil spring in the projecting arm of the toothed bar, allows for the compression
and extension of the volute buffer springs, when the drop bar is in situ or in the
buffer slots.
I also provide a mechanical arrangement by which I can move the drop lever
forward or backward, until it comes directly over the slot holes, and then by turning
the wheel handle the drop bar is lowered into the slot holes; thus effectually coupling
the two cars. I may provide ordinary buffers in addition to the central one, required
for my invention.

page_text: THOMAS FREDERICK REMER 44 West Derby Street Liverpool do hereby declare the
nature of my invention for AN IMPROVED RAILWAY COUPLING ARRANGEMENT 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 an improved method of coupling railway cars and
other vehicles, whereby the danger to railway wagon shunters and generally the work
of coupling railway cars will be considerably reduced.
Referring to sheet of drawings which is intended to form part of this specification
Figures 12 and 3 shew one modification of my invention.
Figures 4 and 6 show a second modification of my invention and a third
modification is shown by figure 7.
In all the figures the same letters refer to the same or similar respective parts.
Figure 1 is a plan shewing the parts coupled together. a is the end rail of one
wagon or car and that of another, the head of one end of one draw bar is jaw shaped ;
as shown by e, into which the head d of another draw bar enters, when the jaws and
head of two draw bars come together, the draw bars are kept extended by means of
volute springs e, which I may repeat on other side of wagon end rail.
The catch hooks g are forced up when the draw bars meet, and fall over projecting
plates, fixed on heads and jaws of draw bars, keeping them together until the drop
bar h, suspended by means of a projecting arrangement, is allowed to fall into slots /
formed in both jaws and heads of draw bars, thus securely connecting them together.
To allow for the motion of volute springs the suspended arm or drop bar his attached
to the end of a projecting piston bar or rod 7, working in a cylinder or guide, and in
which there is a coil spring which allows the backward and forward movement of
piston, and the suspended drop bar h.
f)
I elevate the cylinder or guide by means of a rack bar worked by a pinion m},
which is actuated by means of wheel handle » working level gearing and shaft
P, the
wheel handle is placed in an easily accessable and safe position on the outside edges
of carriage ends. I lift the catch hooks by means of a chain 4.
Figure 2 shows a side elevation of the arrangement described.
Figure 3 is a front elevation and section through jaw and head of draw bar when
coupled and with drop bar in position.
Figures 45 and 6 shew respectively a plan, side elevation and front elevation of
another modification of my invention.
In this latter modification, instead of the level and rack and pinion gearing
arrangement for elevating or lowering the drop lar h, I make use of a lever working
into a slotted vertical slide bars, the lever is inoved by a screwed bar actuated by a
wheel handle u.
Figure 7 shews a side elevation and section, through jaw and head of draw bars of a
third modification of my Invention, in this arrangement the drop lar device is attached
to that side of carriage having the jaw headed draw bar, the upper slot thereof is
countersunk or recessed to receive a projection at the lower end of drop bar h, so that

page_text: the latter can be lifted out of the way of head of draw bar into the recess in jaw, and
the drop bar is thus always over the slot in head, if the two draw bars come together.
I do not wish to be confined to the use of the devices as herein exactly shewn and
described, but I wish to be understood as claiming all such modifications as come
within the spirit of my invention as embodied in my claims.
Having now particularly described and ascertained the nature of my Invention and
in what manner the same may be performed, I claim
1st. The device of coupling railway cars and other vehicles by means of a flexible
draw bar arrangement with suspended drop bar and method of actuating same
substantially as herein shewn and described.
2ndly. The device in its other modifications substantially as herein shewn and
described.
