page_text: I HENRY CHANCELLOR of 23 Shirley Grove, Battersea, in the county of Surrey,
pattern-maker and draughtsman do hereby declare the nature of this invention to
be as follows:-
A shaft; suspended by brackets fixed to wagon end to which is attached two
arms or levers which are bent to suit action. These arms or levers carry the
coupling link. The links are two in number, hinged or jointed on centre pin and
are made to fold or double up. The coupling-link is carried by pin on each side
of link which is placed into slot in levers or arms. The length of slot forms a stop
for pins or trunnions. A weight is suspended from link joint pin which ensures
the position of links; the joints being an easy fit the links are always in a position
for coupling. When raising the levers, the links are withdrawn somewhat, conse-
quent upon their position with regard to the slots and the position of the rocking
or main shaft, and letting go the handle, the coupling link slides forward for
coupling.
When un-coupling; the pressure on link from under side of hook (the levers
rising the while); causes the links to straighten out and is released.
When out of use, the levers hang down with the links; the ends of the levers
being inclined under the wagon.

page_text: I HENRY CHANCELLOR of 23 Shirley Grove Lavender Hill Battersea in the
county of Surrey Draughtsman and Pattern Maker 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 nature of the apparatus which will be understood from the following;
reference being made to the accompanying Drawing in which Fig. 1 is a plan view,
and Fig. 2 an elevation of parts of two railway vehicles coupled according to the
coupling here described.
The apparatus consists of the shaft A supported or carried by brackets and
here after called the rocking shaft which has two arms or levers B.
At or near
the ends of these levers is a slot C of peculiar shape, and further; There are two
links or shackles hereafter called the first or hanging link D and the coupling
link E.
They (the links) vary in length and at the point where they are hinged or
jointed bangs, or is suspended, the weight F.
At a short but suitable distance from this said point, and on or through the
coupling link E, is a trunnion pin H for the use of the levers B, for raising the
coupling.
The centre carrying bracket G is also constructed to serve the purpose of a
jilter, for jilting out, or thrusting backward, (and under certain conditions for
skidding out of the hook) the coupling link E.
The operation is performed through a handle placed and secured, or fixed as
part of the shaft A, and at each end thereof, so that the coupling is available from
either side of the vehicle.
The apparatus complete is also fixed to each end of the wagon or vehicle.
The rocking shaft A, with the arms or levers B forged, stamped, and, or
otherwise fixed to it are of wrought-iron. The length of the arms or levers B
is determined by the length of the links D and E to be used, together with the
relative position of the rocking-shaft A. The levers B if desired may be extended
as dotted in Fig. 2 and a block answering as the end of the slot C with pin O to
secure it or fixed on the end by two small bolts (one each side of the slot C) the
pin or bolts to be of sufficient strength so that in case of breaking the link D, the
pin, Owould also break, thus retaining the apparatus so far uninjured; but if
the vehicle end is strong enough together with the fixing of the shaft A every
other part necessary being proportionately strong, then; should the link D break
the coupled vehicle or vehicles would be held as coupled the strain in that case
would be on the trunnion pin H and the arms or levers B. The slots C in the
arms or levers B are so situated and of such a form as to obtain the greatest
amount of coupling range the apparatus so fixed will admit of and to depart from
the lengths and centres would necessitate a modification of the arrangement.
The first or hanging link D is made of wrought iron and of two pieces to suit
hook as shewn; the ends of which may be stamped, or forged and shut unto the

page_text: sides; or made of one piece each side as
most convenient or suitable, or finished
as one piece throughout if an adapted book be used. If of the former plan it is
attached to hook in the ordinary way with horizontal pin etc.
+
This link D has an elongated eye or slot K on or in each side as shewn in
Drawing, which serves two purposes mainly-first; to allow of the thrust backward
when the jilting bracket G is struck under certain conditions, and secondly to take
any undue strain off the trunnion pin H when the coupled vehicle is drawn
forward or when the links D and E are straightend out by traction. This slot K
may be made at the hook ends of the link D as shewn dotted P as is hereafter
shewn.
At the ends of links D and E where they are jointed or hinged, and on the pin J,
and between the link D, hangs or is suspended the weight F made of iron with
shank of convenient length, which is of such a shape that it is not caught or
jammed in the link D if it should under any circumstances strike it, and of such
bulk or weight that it shall serve the purpose of keeping the trunnion pin H at its
lowest point in the arm slots C and consequently the coupling link E of which in
use it forms a part, where-ever that point may be located.
Its bulk or weight must not interfere with the object of the coupling link E.
At the place or point from where it is suspended it forms a distance piece.
The coupling link E is made of wrought iron with round eye holes where it is
hinged or jointed to the link D and is looped at the other end describing a semi-
circle or made somewhat elliptical as is most suitable. At a short but suitable
distance from where it is hinged or jointed is another round eye-hole in both sides
of the link, where is inserted (if not otherwise attached) a trunnion pin, passing
horizontally right through link E and slot C of the arms B and secured at the sides
(allowing all necessary clearances) with washers, screwed nut, and pin, or by any
known method of secure fastening, thus taking the shape of a bolt.
The arins or levers B to stand out free and clear of all projections, or that which
may prove an obstruction to their free and easy use.
All the working parts of the apparatus to be of the easiest and loosest
description compatible with its efficiency.
To reduce the friction on the trunnion pin and of the arm slots C, ferrule rollers
could be put on the trunnion pin ends, where they engage with the arm slots C if
necessary. The centre bracket G is of iron, stamped, forged. or cast, and is slipped
over the rocking shaft A from its front, and is filled up at the back with a suitable
piece of wood, or iron, and secured. The other necessary brackets are threaded on
from the ends, two of which would be required as dotted L to keep the rocking-
shaft A in position, unless the bracket Ġ was extended far enough toward the
arms B to effect that object; or otherwise done or effected. The centre bracket G
not only answers the purposes here indicated but also is so constructed to serve
the purposes of a jilter under certain conditions, and when the vehicles are in closer
proximity, that of a skidding purpose to the coupling link E. The draw bar plate
may be made to effect the object of jilting bracket G relative to jilting and skidding,
but taking the hooks as projecting a certain distance from the headstock recesses
or holes would be necessary as dotted M, to allow of the thrust backward of the
hanging link D, provided the elongated eye or slot was in that end of the link as
dotted P; when the amount of the suspended weight could be reduced, or the draw
bar plate (or an additional plate to serve the purpose) may be used retaining the
elongated eye or slot K with the weight substantially as shewn. The length of
the elongated eye or slot, must be such as to allow the trunnion pin H. to find its
way into the recess of the slot C of the arms or levers B.
A handle of suitable length and in the most convenient position (omitted from
the drawing for the sake of clearness) is placed and secured or fixed as part of the
shaft A which-ever is of the most utility in practice on each end of the shaft A
for the use of the operator to work or effect the coupling. If the handles are
fixed; to be in such a position that their weight might be utilized to assist the
arms or levere B in keeping the apparatus as far back and under the vehicle end

page_text: as the headstock will allow or admit of. If placed on and secured it would be
necessary to have a stop or projection fixed to the rocking shaft A for the handle
to operate or catch against, and when out of use to hang down independently of
the shaft A the headstock forming a stop for the same. In either case the
apparatus is in a swinging position.
It will now be seen, that by operating with the handle on either side toward
vehicle to be coupled, the levers or arms B are raised and with them the links D
and E with weight F suspended; when the coupling link E collides with the hook
to be coupled the levers B still rising, the coupling link E rides over the hook and
falls forward and down into its destined place, and ceasing to hold the handle (the
coupling being performed) the arms or levers B are resting on the trunnion pin.
When uncoupling in the longest range of the links D and E as described, the
coupling link E does not strike the jilting bracket, but comes in contact with the
underside of hook; the levers B rising the while, which causes the links D and E
to straighten out until the coupling link E is released from the hook. When
uncoupling under shorter ranges the coupling link strikes the jilting bracket G
and is thrust backward; the trunnion pin H. finding its way into the recess of the
arm slots C and assuming a perpendicular position makes a circuit out of the hook.
In still closer ranges it strikes the jilting bracket G and is skidded out, behaving
substantially as before.
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. In a coupling for railway wagons or vehicles the combination of the shaft A
with its levers or arms B, and their peculiar slots C as applied to the trunnion
pin H such as substantially as described with reference to the Drawing and for the
purposes set forth.
2nd. The combination of the elongated eyes or slots, K, of the link D, in their
relation to the arms B of the shaft A; the trunnion pin H, and of the slots Cas
affected by the jilting bracket G, substantially as described and for the purposes
set forth.
3rd. The combination of the weight F as for the purposes set forth relative to
the slots C in the arms B of the shaft A with the trunnion pin H of the link E.
4th. The combination of the jilting and skidding bracket G or other plate
answering or serving that purpose, with its relative uses as applied to the slots C
of the arms B such as substantially, as described and shewn in the Drawing.
