Improvements in Pneumatic Horse Collars.
I, FREDERICK RICHARD BROOKE, residing at No. 52, Broadway, in the City of
New York, County and State of New York, United States of America, Manu-
facturer, 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 annexed drawings to which reference is made, fully illustrate my inven-
tion, in which-
Figure 1 represents a front view of my device showing a portion of the collar
opened, exposing the interior thereof.
Figure 2 is a transverse sectional view, taken on the line -, Figure 1.
Figure 3 is a front view, part sectional of the brace frame.
Figure 4 is a vertical sectional view of the hinge plate, detached from the
bracing frame.
Figure 5 is a plan view of the same.
Figure 6 is a detail view of the two meeting ends of the frame, showing the
spring catch pivoted to the hollow tube, the latter and the socket screwed res-
pectively to the lower end of each brace frame.
Figure 7 is a perspective view of the plate.
Referring to the accompanying drawings, by letter, A designates the horse
collar, comprising two sections a, a, hinged frame and inflated sack, which
frame is hinged at the upper ends and fastened together at its lower ends by
sockets and clasp, further hereinafter described.
This collar has the usual outer casing b, in which is inserted the brace frame,
composed of two sections 61, 61, formed preferably of gas-pipe, or other suitable
metal tubing bent in the desired shape to conform to the outlines or shape of the
animal's neck and the sections screw-threaded at their upper and lower ends,
as at c, c, to engage respectively the hinged plate and the lower clasp connec-
tions. The plates aforesaid are constructed alike as well as the brace frame,
and a description of one will answer for both.
The plate comprising two sections d,d, is constructed in skeleton form, the
same being broad and curved to give the desired shape to the collar where it rests
upon the animal's neck, the said plate having a cut-away or recessed portion and
rovided with lugs e, e, having eyes f,f, for the passage of the securing bolt g,
which forms the hinge or pivoted connection for the two plates, and at the
pposite end to that having the lugs, the plate is constructed with an enlarged
ortion h, which is female screw-threaded to receive the male threads on the
pper end of the brace frame aforesaid. Within this recessed portion is seated
curved block a', of light material, preferably wood, that is held in place by
screw i, passing through a perforation j, in the plate.
The brace frame is further provided with perforations k, which are female
crew-threaded to receive the fastening screws by which the casing is held to the
race frame.
B designates one section of the clasp, consisting of the tubular portion /

page_text: and a solid back m, which is female screw-threaded, in which the lower threaded
end of the frame is secured; the tubular piece is also provided with a collar n,
and within this tube is pivot end the rear end of a spring catch or hook o, having
a coiled spring o¹, whereby the hook is kept in engagement with the edge of the
opening p, in the opposite section F, which latter is provided with a solid
projection, having female screw threads to engage the male thread on the
lower end of the frame on the side or section of the collar. The outer casing
is constructed in two sections and so shaped as to conform to the shape of the
animal's neck and shoulders, and each section comprises a single piece of leather
which is open and at intervals, the edges r, are provided with perforations s,
which register with the female screw-threaded perforations in the brace frame
when the edges of the casing are lapped over one another, and upon the frame.
C, C designate clamping plates, which are curved from top to bottom to con-
form to the shape of the brace frame, and each is provided with perforations t,
that register with the perforations in the edges of the casing and perforations
in the frame, and at the upper end of these clamping plates are formed perfora-
tions, through which passes the pivotal bolt by which the two halves of the
collar are hinged to one another. Within the casing is arranged an air-sack.),
which is inflated through the tube v, by an air pump in the usual manner.
E, E, designate the tug-eye secured to the clamping plates and frame;
and w, w, are the rings for the reins, and the rings being screwed into the brace
frame where they are held firmly in place.
It will be observed from the above description when taken in connection with
the annexed drawings, that after placing the inflated tube within the casing
as well as the hinged brace frame, the two edges of the casing are lapped over
one another and upon the brace frame, after which the outer plates are placed
in position, covering the lapped edges of the casing, when the screws,, are
screwed through said plates, casing and into the brace frame, thereby clamping
the edges of said casing between the outer plates and the sectional brace frame,
and the broad plates at the top serve a double purpose, viz: that of a hinge,
and to broadly span from the front to the rear at the top of the collar,
In. locking the two sections of the collar together, the lower portions are
brought together when the tubular portion having a spring catch or hook, will
enter the opposite tubular portion and the hook will engage the opening P
thereby firmly holding the two free ends of the collar in a locked position, and
when it is desired to unlock the collar the spring-catch is pressed inward and
the hooked end thereof is disengaged from the opening p, in the tube, when
the collar may be opened; the two sections swinging on their hinge at the top
of the collar, and the female screw-threaded plate, having the light filling in the
recessed portion thereof, not only forms an excellent hinge for the collar but is
readily attached to the screw-threaded upper end of the brace bar.
Between the inner brace frame and the outer plate is secured a T-shaped
plate, having perforations through which pass the screws which hold the outer
clamp plate in position, and a perforation, through which passes the outer end
of the inflating tube or nozzle, which plate is designed to retain said nozzle in
position and prevent displacement of the same.
Within the rubber sack is arranged a filling e¹, which is designed to protect
the animal from pressure of the brace frame, should the collar become punc-
tured or the air escape therefrom through any reason whatever, thus providing
the collar with means whereby the collar is rendered serviceable under all cir-
cumstances, and a collar as herein described is durable, soft and easy to the
neck and shoulders of the animal, ornamental as well as cheap to manufacture.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The combination in a horse collar comprising two sections, of the hinged

page_text: plates provided with the female screw-threads and the brace frame having the
end male-threads, adapted to engage the threads in the plate, substantially as
described.
2. The combination with the sectional horse collar, comprising an outer cas-
ing, an inner inflated pad, of a hollow brace frame, formed of two sections and
plates secured to the upper ends of said frame, having perforated lugs adapted
to receive a bolt whereby the two sections of the frame are hinged together,
substantially as described.
3. In combination with the inflated pad, casing and brace frame, of the
hinged plate, and filling therefor, the catch-sleeve or tube provided with a solid
portion having the opening to receive the lower end of the brace frame, and
provided with the spring catch, and the tubular end or socket having the open-
ing to engage the hook of the spring catch and provided with the opening in the
solid portion to receive the lower end of the brace frame, substantially as
described.
4. In a pneumatic horse collar, the combination with the inflated pad, and
casing therefor, of the sectional brace frame formed in two parts, the plates
secured to the upper end of each section, forming a hinged connection and means
substantially as described for locking the lower ends to one another.
5. In a pneumatic horse collar, the combination with the casing, inflatable
sack, and clamping-plates, of the brace frame comprising the hollow sections,
provided with the female screw-threaded perforations, and upper hinged plate
composed of two sections and provided with the enlarged portion, female screw-
threaded to engage the male threads on the upper end of each section of the
frame and the locking device, each portion thereof having the female screw
threads adapted to engage the male screw threads on the lower end of each
frame section, substantially as described.
6. The combination of the T-shaped plate having perforations, inflatable sack
provided with the inflating tube, the brace frame and outer clamping plates,
said T-shaped plate adapted to engage said inflating tube, whereby the latter
is held in position on the collar, all substantially as described.
7. In a horse collar, the combination with the inflated pad casing, frame and
clamping strips, of the hinged plate having the enlargement to engage the upper
end of each section of said frame, substantially as described.
S. In a horse collar, the combination with the casing, brace frame, securing
plates, and inflated sack, of the filling composed of soft material arranged within
the sack and adapted to serve the purpose of a pad when the sack is not inflated,
substantially as described.
9. In a pneumatic horse collar, a partial stuffing for the inflatable sack, inter-
posed between the rear portion of the casing thereof and the pressure frame at
the front of the collar, substantially as described.
10. In a pneumatic horse collar, the loose filling arranged within the infla-
table sack thereof and interior of the casing, and interposed between the
shoulder portion of the sack and casing, and the pressure frame or frames, sub-
stantially as described.
