PROVISIONAL SPECIFICATION.
An Improved Construction of Horse Collar.
We, FRANCIS HEATHCOTE WENMAN, of 56 Finsbury Pavement, City of London,
Commission Agent, and HAROLD BETTELEY, of 200 White Horse Road, Croydon,
Surrey, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to a novel construction of Horse Collar, the object being to
make those parts on which the strain is put slightly yielding and so remove the rigid
contact with the shoulders of the horse which is so objectionable in the present make
of collar.
For the purpose of our invention, we mould a tubular frame in rubber both ends of
the frame being open. Those parts of the frame or tube where the strain is put are
of increased thickness proportionately to the strain imparted to resist undue com-
pression, the air being free to escape and fresh air to enter after the removal of the
pressure.
By this means the collar is kept cool and is not liable to chafe the shoulders of the
animal.
If desired parts of the collar can be covered with canvas, such as where the hames
bear and the trace rings rub, and the inside of the collar may be provided with a
canvas necklace, or a separate canvas necklace can. be first placed on the horse for
the rubber collar to rest upon, or a metal or compound metal may be fitted to the
inside of the collar as a liner.

COMPLETE SPECIFICATION.
An Improved Construction of Horse Collar.
We, FRANCIS HEATHCOTE WENMAN, of 56 Finsbury Pavement, City of London,
Commission Agent, and HAROLD BETTELEY, of 200 White Horse Road, Croydon,
Surrey, 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 relates to a novel construction of Horse Collar, the object being to
make those parts on which the strain is put slightly yielding and so remove the rigid
contact with the shoulders of the horse which is so objectionable in the present make of
Collar.
For the purpose of our invention, we mould irregularly shaped tubular frames A, B,
Figures 1 and 2 in indin rubber for each shoulder portion of a Collar and with both
ends C, D, of each frame open. In making up a Collar with two of such frames as
we show at Figure 3 (this being half in section) we have a pipe communication at E
for the free passage of air from one side frame to the other. Those parts of the
frames or tubes A, B, where the strain is put, are of increased thicknesses, as at F, G,
Figure 4 (sectional plan), the thickness being in proportion to the strain imparted to
resist undue compression. Air has free admission and escape by the top openings (, C,
to which at Figure 3 short tubes H H are arranged, the exposed ends being protected
by the cap I.
The hollow openended frames A, B, can be covered with leather, canvas, or other
material J like ordinary packed Collars, or only at those parts where the hames bear
and the trace rings rub.

page_text: Tne moulded india rubber open-ended frames A, B, and the connecting tube E can
be of any dimensions according to the size of the Collar. Thus for a powerful draught
horse having to draw heavy loads, a Collar of more substance and strength would be
necessary than for a horse employed for drawing a carriage, or a light vehicle, such
as a gig, or a dog-cart.
Any desired amount of packing K can be adopted with our cushions A, B, and
between them and the covering material J.
The inside of the Collar may be provided with a canvas neeklace, or a separate
canvas necklace can be first placed on the horse for the rubber Collar to rest upon,
or a metal or compound metal may be fitted to the inside of the Collar as a liner.
We are aware that Collars for animals have heretofore been made with air chambers
to give them yielding properties on the application of pressure and also to serve as
cushions against the animal's shoulders, but in all those cases the air vessels have been
like bags or bladders for confining the air therein, which not only destroyed the
intended usefulness of the Collar by its enlargement due to the rapid expansion of the
confined air by heat from the animal, but it also altered the shape and consequent fit
of the Collar, and produced wrinkles which after a short time caused irritation and
sores on the animal's shoulders, thereby rendering him unfit for work.
We have shown the india rubber frames A, B, each as a single piece but each frame
may be composed of several pieces prepared separately and moulded or cemented
together to constitute a frame. Each portion has free air passage as at C, D, and if
desired, the tube E can be dispensed with, the lower ends of the frames being then
provided with short tubes, as at H, H, for free ingress and egress of air.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The manufacture of india rubber frames with open ends and moulded to shape
adaptable as cushions in animals Collars, as described and substantially as shown at
Figures 1 and 2 of the annexed drawings.
2. The manufacture of animals Collars with open ended shoulder frames connected
by tube at bottom and with free exposed ends at top as yielding bodies for the purposes
described with reference to Figure 3 of the annexed drawings.
