naliway carriages and er vehicles.
I, FREDERICK HENRY CHEESEWRIGHT of 23, Gower Street, Bedford Square, in
the County of Middlesex, Civil Engineer, do hereby declare the nature of this invention
to be as
follows:-
This invention has reference to centre buffing and coupling apparatus for railway
carriages and other vehicles.
In centre buffing apparatus as ordinarily constructed with buffer heads and rods
working through guides, the plungers or rods are subject to considerable wear, and
are consequently liable to fracture.
Now this invention relates to a construction and arrangement of centre buffers such
as will obviate this defect, and with which there is combined coupling gear, the hooks
of which are so arranged that they can be removed from the buffer heads without
withdrawing or displacing other parts. The buffer plungers are made hollow and
arranged to slide in buffer cases in which springs of any suitable kind are introduced
between the rear ends of the buffer plungers and the rear ends of the buffer cases;
suitable draw springs being also provided as usual. The draw bars extend through
the head stocks and buffer cases into the buffer heads (which are formed with slots or
openings (preferably on the top for automatic coupling) to admit coupling hooks)
terminating each in an eye. In the case of two opposing buffers, the outer end of the
eye of the draw bar in the one buffer head serves as a pin on which a coupling hook
can be placed and on which it can turn within certain limits determined by suitable
projections or stops. This outer end of the eye has in cross section a circular form
with the upper and lower parts flattened. The eye of the coupling hook is formed at
its lower part with an opening or slot of sufficient width to admit of passing the eye
of the hook over the flattened surface of the before mentioned outer end of the eye of
the draw bar. When the hook is placed with the sides of the opening into its eye
parallel or approximately so with the flat surfaces of the front end of the draw bar
eye and passed over the same, then a very partial rotation will bring the opening of
the eye into such a position that the eye of the hook will not become disengaged.
The hook proper can engage with the eye of the draw bar located in the buffer head
attached to an adjoining vehicle.

page_text: Improvements in Centre Buffing and Coupling Apparatus for
Railway Carriages and other Vehicles.
I, FREDERICK HENRY CHEESEWRIGHT, of 23, Gower Street, Bedford Square, in
the County of Middlesex, Civil Engineer, 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 :-
This invention has reference to centre buffing and coupling apparatus for railway
carriages and other vehicles.
In centre buffing apparatus as ordinarily constructed with buffer heads and rods
working through guides, the plungers or rods are subject to considerable wear, and
are consequently liable to fracture.
Now this invention relates to a construction and arrangement of centre buffers such
as will obviate this defect, and with which there is combined coupling gear, the hooks
of which are so arranged that they can be removed from the buffer heads without
withdrawing or displacing other parts. The buffer plungers are made hollow and
arranged to slide in buffer cases in which springs of any suitable kind are introduced
between the rear ends of the buffer plungers and the rear ends of the buffer cases,
suitable draw springs being also provided as usual. The draw bars extend through
the head stocks and buffer cases into the buffer heads, (which are formed with slots or
openings preferably on the top for automatic coupling) to admit coupling hooks of
the form hereinafter described and shown in the drawings, or other form suitable for
the requirements of any particular case. In the case of two opposing buffers, the
outer end of the eye of the draw bar in the one buffer head serves as a pin on which
a coupling hook can be placed, and on which it can turn within certain limits
determined by suitable projections or stops. This outer end of the eye has in cross
section a circular form with the upper and lower surfaces flattened.
The lower or hinge end of the coupling hook is provided with a slot cut at such an
angle and size as to admit of its passing in one position only, over the flattened surface
of the eye of the draw bar. The hook proper will couple or connect with the eye of
a draw bar within the buffer head attached to an adjoining vehicle, the hook always
assuming a position that makes this operation automatic if desired.
Referring to the accompanying sheet of drawings,
Fig. 1 is a longitudinal vertical section of centre buffing and coupling apparatus
according to this invention shown as applied to the headstocks of two adjacent
vehicles.
Fig. 2 is a plan of the same.
Figs. 3 and 4 are respectively a front view and back view of one of the centre
buffing apparatus.
The buffing, coupling, and drawing apparatus is constructed as follows:-
1. hollow buffer plunger or head formed with a slot or opening 2 in its upper and front
portions; 3, buffer case curved or recessed at 3; 4, india-rubber spring introduced

page_text: between the buffer plunger or head 1 and its containing case 3; and 5, draw-bar
extending through the head-stock 6 and buffer case 3 into the buffer plunger or
head 1 as shown. 7, eye or enlarged outer end of the draw-bar, which serves to
retain the buffer plunger or head within its case, as more clearly shown in Fig. 2,
and to receive a coupling hook 11. The transverse part of the eye at its outer end
is of a peculiar cross section, that is to say it is formed as a circle with upper and
lower surfaces 7ª, 7 flattened (see Fig. 1). 8 draw spring; 9 and 10 plate and nut
respectively for securing the draw-bar, and by it the buffer plunger or head in
place. 11 coupling hook provided at one end with an eye 12 formed with an
opening or slot 13 sufficiently wide to pass over the flattened part of the draw-bar
eye 7 when the hook is turned with the sides of the opening or slot 13 parallel or
approximately so with the flattened surfaces 7, 7b, of the eye 7. A partial rotation
of the coupling hook 11 about the said transverse part as a centre (after the latter
has entered the eye 12) will bring the opening or slot 13 into such a position as to
prevent accidental disengagement of the hook from the transverse part of eye 7.
The rear end of the hook is formed with a flattened surface at 14 adapted to bear
against the lower surface of the interior of the buffer plunger or head 1, and thereby to
limit the upward movement of the coupling hook. The part 15 of the buffer plunger
or head 1 serves as a stop to limit the downward movement of the hook when
uncoupled. The hook proper of the coupling hook is curved or inclined at its outer
end to adapt it to rise over and enter the oye of the draw-bar of an adjacent vehicle
as shown when two vehicles fitted with my improved apparatus are brought
together.
Means may be provided for limiting the outward movement of the buffer plunger
or head within its case, and thus prevent displacement of these parts in the event of
breakage of the draw-bar. For this purpose, a pin or projection carried by the
buffer case and entering a slot in the buffer plunger or head may be used. Or the
buffer case may be provided at its outer end with a bush or gland, through which
works the buffer plunger or head, which carries a flange or projection adapted to
bear against the inner end of the bush or gland, and limit the outward movement.
The various parts of the apparatus may be constructed of any suitable materials.
Metal springs may be used in lieu of the india-rubber springs 4 and 8, but I
prefer to use springs of the latter material.
Having now particularly described and ascertained the nature of this invention, and
in what manner it is to be performed, I declare that what I claim is
11
1. In centre buffing and coupling apparatus, the construction and arrangement
substantially as described whereby the coupling hook is made capable of removal
without disturbing other parts.
2. Centre buffing and coupling apparatus comprising a buffer plunger or head
and a draw-bar capable of independent movement, the arrangement being substantially
such as hereinabove described.
3. My improved centre buffing and coupling apparatus substantially as hereinabove
described with reference to and shown in the drawings annexed.
