Pneumatic Horse Collar.
I, LAURON INGELS of Seattle, in the State of Washington, U.S.A., Gentleman,
do hereby declare the nature of my invention for A PNEUMATIC HORSE COLLAR,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention consists of an improved horse collar having within it on each side
an air tight bag or sack which may be inflated with air thus forming an elastic
cushion where it comes in contact with the horse's shoulder.
In the drawings:
Fig. 1, represents a complete collar, the air bags being shown in dotted lines.
Fig. 2, is an air bag removed from the collar, and
Fig. 3, a cross section on the line m, n, of Fig. 1.
In using collars stuffed with straw, hair or other similar material as has
heretofore been common it is practically impossible to always secure a uniform
pressure upon the shoulder. This unevenness of pressure causes sores, which
besides being a source of irritation to the horse, frequently incapacitates him from.
work. Although collars have been made in which the whole collar was composed
of an air tight bag, this is not practical, as a certain amount of stiffness and rigidity
is required. My collar is made with the roll or rim, b, the same as in the ordinary
collar being stuffed with straw, hair or other similar substance or in any manner
which will make it firm and comparatively rigid, the object being to have it
maintain the shape of the collars and prevent the hames from pulling off forwards.
The space d, at the bottom of the collar is similarly stuffed.
On each side, however, the main body of the collar has placed inside of the
leather C, which forms the outer casing, an air tight sack a, made of rubber or other
similar air retaining fabric. This sack has at some convenient point a tube, as f,
which projects through the casing c, and has within it a check valve or some other
means for preventing the air from escaping. Any suitable device for closing these
tubes may be used.
By thus placing the air sacks only under the hames where the pressure comes,
leaving the remainder of the collar as usual, the benefit of the air cushion is
obtained without losing all the rigidity necessary to have it retain its shape. If
found desirable the roll of the collar may be made of metal or other stiff material
so as to be more stiff and rigid than usual.
An ordinary collar may also be made over by simply removing the stuffing from
the sides and inserting the air sacks.
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 horse collar having the main or pad portion on each side without any
stuffing material, thus forming two cavities, in a combination with an air tight bag
or sack within each cavity and means for inflating the same with air and retaining
it therein, substantially as shown and described.
2. A horse collar having the casing or cover c, the roll b, containing a stiffening
material, throat portion d, containing any customary stuffing material, and inflated

for filling the body or pad portions of the collar on each side, and means
for retaining the air therein, substantially as shown and described.
