Improvements in Pneumatic Horse Collars.
I, HARRY CLARKE, of 124 Broad Street, in the City, County, and State of
New York, United States of America, Collar 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 :-
This invention relates to collars for horses, and the object thereof is to provide
an improved device of this class, which is so constructed and arranged as to retain
its proper form, and also to prevent galling, chafing or otherwise injuring the
animal; and with this and other objects in view the invention consists in the
construction, combination and arrangement of parts hereinafter described and
claimed.
The invention is fully disclosed in the following Specification, of which the
accompanying drawing forms a part, and which represents a transverse section of
my improved collar.
In the accompanying drawing forming part of this application A. represents the
main body of the collar, or that portion thereof which forms a bearing for the
harness and which is adapted to surround the neck of the animal and to rest upon
its shoulders.
This part of the collar is of the usual form in cross section being almost elliptical
with the outer or bearing surface thereof slightly compressed, and the inner portion
thereof is composed of a rubber tube B. which is enclosed by a strong canvas tube
or casing C, and outside of the canvas casing or covering and on that side thereof
which comes in contact with the shoulders of the animal or bears thereon is a
covering D. of fine wire mesh or netting which extends from d to d¹ and outside of
the wire mesh or netting is secured a thin casing or covering E. of leather which
entirely surrounds and encloses the wire mesh or netting and over the canvas
casing or covering C. and extending from d. to d', is a spring metal covering F.
preferably of steel and shown in the drawing in heavy black lines, and forming a
continuation of the thin leather covering E, by which the wire mesh or netting i
enclosed is a heavy leather covering G, which extends from the point d, over the
steel F. and is formed into a tubular attachment K, with which collars of this clas>
are provided said tubular attachment K. being adapted to hold the hames of the
harness in place and provided with a metal lining L. by which it is retained in
form, and the general form of this tubular attachment K, is, as will be understood,
the same as that of the body of the collar.
The body A, of the collar is filled in with abestos fibre as shown at M, and
afterwards it is inflated with air by a process similar to that employed in making
pneumatic collars, the collar being provided with an air nozzle with which au
air pump is connected. These features of construction, however, form no part of
this invention and are not shown.
The advantages of my improvement will be apparent with all those familiar with
this class of devices, and the operation thereof. The canvas casing or covering C.
for the rubber inner tube serves to retain the collar in proper form as does also the
wire mesh covering or casing applied thereto and this operation is aided by the
packing of asbestos within the collar.
This construction also serves to prevent the overheating of the collar and the
consequent galling and chafing of the animal to which it is applied.
The annular metal plate or covering F. which is preferably of steel, and the

page_text: heavy leather covering which is placed thereover also aid in retaining the collar in
its proper form and provide the best possible bearing surface for the hames or that
portion of the harness which in practice is connected with the collar.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. A collar for horses, comprising the usual body portion A, which is composed
of an inner tube of rubber, a tubular covering or casing of canvas, said canvas
covering or casing being provided on the inner side, or bearing surface with a
covering of wire mesh, over which is placed a covering or casing of thin leather,
and said canvas tube or covering being also provided on the outer side with a steel
or other metal plate or covering over which is placed a covering of leather,
substantially as shown and described.
2. A collar for horses. comprising the usual body portion A, which is composed
of an inner tube of rubber, a tubular covering or casing of canvas, said canvas
covering or casing being provided on the inner side or bearing surface with a
covering of wire mesh, over which is placed a covering or casing of thin leather,
and said canvas tube or covering being also provided on the outer side with a steel
or other metal plate or covering over which is placed a covering of leather, which
is also formed into a tubular attachment as E. which is provided with a metal tube
or lining, substantially as shown and described.
3. A collar for horses, or other animals, which is filled in or provided with a
packing of asbestos fibre and which is also adapted to be inflated with air,
substantially as shown and described.
4. A collar for horses or other animals, the body portion of which is filled in or
provided with a packing of asbestos fibre and adapted to be inflated with air, said
body portion being also provided with a tubular attachment as K. substantially as
shown and described.
5. A collar for horses or other animals, the body portion of which is filled in or
provided with a packing of asbestos fibre and adapted to be inflated with air, said
body portion being also provided with a tubular attachment as K provided with
an inner tube or lining substantially as shown and described.
