ROBERT COOKE SAYER 3 Summer Hill Villas, Maindee Newport Monmouthshire,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
1st. For trucks having their central bearing longitudinal timbers a considerable
distance apart
See Drawing Fig. No. 1 which shows the frame AA of one end of a truck in
Longitudinal Section. B is the draw-bar having attached a fixed inclined jaw D at
the end and the double or anchor-hook C hinged to it resting upon D. A shackle E
is fixed upon B and has attached by the trunnions E the ends of a loop of bar
iron F that passes through apertures in the buffer plank A³ and round at the front of
the hook C in one piece: the apertures in A³ are bell-mouthed horizontally and
vertically to allow of the play of F when passing round curves, and rising and falling
when coupled to trucks of different heights: F has attached supporting snugs F to
keep F level with the centre of C: & is a transverse tube reaching to either side
of the truck and carries an arın H with balance weight H and is attached to E
by links J.
K is a metal rod reaching across the truck and carries the two arms L. that are
bent so that when raised they shall take against the underside of a coupled loop
resting in the upper hook and raising it over C. or if the coupling loop should be
within the lower hook, L will take against the stud C and raise C, thus releasing the
coupling in either case: L' are arms attached to L to prevent their falling.
TO COUPLE.
G is forced down when E and F are driven forward and the trucks meeting F takes
into the upper or lower hook according to the height of the trucks.

page_text: 2nd. For trucks having their central bearing longitudinal timbers very close
together
See Drawing Fig. No. 2 which shows the frame AA of one end of a truck in
Longitudinal Section B is the draw-bar which is cut short and not allowed to pass
through the buffer plank A², and is formed at the end B' as shown and there supported:
B is formed flat for a portion of its length B' to B³ and it carries a shackle E to which
is attached the links F (also formed flat) these have hinged at their ends the loop C
and hook C³ (united and working together): F has snugs F to keep it in place
and C has a projection C carrying a link or chain C which is attached to the buffer
plank at CK is a metal rod reaching across the truck having a loop in it K': E has
a projection E carrying the ends of two diagonal handles G which respectively reach
to either side of the truck: G swivels at G²: E has attached by a chain passing
over the pulley H the balance weight H which is kept in place by the two diagonal
chains H³: A is bell-mouthed (as explained previously) but at the single aperture

An Improved System of Coupling for Railway Vehicles.
ROBERT COOKE SAYER 3 Summer Hill Villas Maindee Newport Monmouthshire,
Civil Engineer, do hereby declare the nature of my invention for COUPLING RAILWAY
VEHICLES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
See Drawings Sheets Nos. 1 and 2 which show in Longitudinal Section and Plan
respectively portions of the end of a truck with a Coupling attached where a represents.
the frame the buffer: C is the draw-bar which is turned up in the form of a hook
at C: the two transverse bolts d keep the usual end spring (not shown) from drawing
it out of its place, while the space between it and the buffer plank allows the play
of the spring.
E is a link the inner end of which works within the hook of C, the other ends
are attached by the bolt F to the hook and link head G, the ends of E carry at E²
projections that have slots, part of which is horizontal and part vertical as shown,
F also has snugs at the bottom to keep it in place when drawn in: the web H thai
connects the link and hook G takes against the slot projection E of E and prevents
its falling below the position shown, although it can rise to any extent (but not so far
that its centre of gravity shall pass behind F): the back hook J of G carries a
suspended hook K. whose tendency is to drop vertically whatever may be the position
of G: G also has a projection Lagainst which the nose M (that is attached to the
bent rod 0, and is supported by the bolt N, that works in the slots at E) works:
M also has a back projection P: O is able to work in the eliptical bearing and has
attached the bolt R (provided with a rounded nut and shoulder above) and carries the
ends of the two slotted levers S each formed as shown of a bent and flattened round
rod and carries a weight S³, and each rest between a nut and shoulder (similar to
those carried by R) that are supported by a vertical bolt T that is screwed into the
buffer plank.
-
The weight S thus causes I and consequently M and N to be forced to the upper
part of the slots at E, but upon $ being risen N is made to descend the vertical
portion of the slots (should it be opposite to them): and again upon S being forced
backward or forward in the direction of the arrows R and consequently M and N are
caused to travel the horizontal portion of the slots, and when the motion is forward
the point of M takes against L of G and elevates the link of G to a horizontal position,
and then N coming in contact with the end of the slot forces G and E forward until
the inner end of E takes against C of C: K will have fallen but P of M is the far end
of the slots and they do not meet.
U is a spring connecting O and E.
The aperture Z in the neutral axis of the buffer plank is made conical to allow E
ta radiata to the sh

page_text: Thrust back S toward the truck which raises the link of G and pulls G and E out,
as the truck to be coupled approaches the link of G will take upon its hook of G, and
rising upon it will fall behind the main hook. Should there be a very unusual
difference between the heights of the trucks, by forcing S down G and E will be
raised until E comes in contact with the top of the aperture 2. Should the curve be
so sharp that the lateral allowance provided by the link of G be not sufficient, pull or
push over S until E comes in contact with the side of Z.
TO UNCOUPLE.
"Buff up" which (whether the spring U is or is not used) causes the back of G
and consequently K to take against the buffer plank and forces the hook of K below
the level of the projection P of M (N is the other end of the slot) but by thrusting S
outward brings P over K when, upon rising S, N is drawn down the vertical slot and
raises the link of G from the other hook, and it is free.
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:
1st. The construction and general arrangement of, and mode of working the
Couplings substantially as described.
2nd. That the Coupling will connect with another vehicle only when arranged to
do so, substantially as described.
3rd. That the Coupling of two vehicles is effected without the necessity of the
operator passing between the vehicles, substantially as described.
4th. (a) That the whole of the parts are so freely put together, the liability of being
made rigid by corrosion is climinated: (b) that physical force
used for the action of
all parts so that a little corrosion is immaterial, substantially as described.
5th. (a) In the event of a Railway Accident damaging the Coupling a new one
(or any single part) may be attached in the briefest possible time: (b) the Coupling
being radial the strains are taken direct, substantially as described.
6th. (a) That the necessary elasticity or play of the Couplings (for the purpose of
starting trains) is divided between the Couplings of the two vehicles coupled: (b) that
there is nothing requiring adjustment when a truck has to be tipped up for shipping
purposes: (c) that there are no pendants or projections that can cause danger to
animate or inanimate objects, substantially as described.
7th. The ability of Coupling and uncoupling with the usual existing vehicle
Couplings, in the same manner without any alteration to them substantially as
described.
