Specification Accepted, 29th Apr., 1887.
I, WILLIAM HARLEY of 3 Peter Street, Whitechapel, Liverpool, in the County of
Lancaster, Provision Merchant, 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 horse collar of that kind having two independently
movable collar pads connected with each other by a rigid yoke reaching from one side
to the other of the horses neck so as to hold the pads from spreading apart, and
hame-tugs, connected by pivots with the ends of the yoke and with the pads for
attaching the traces to the collar.
.
The object of the invention is to improve the construction of horse collars of the
kind referred to in several particulars, as will hereinafter appear and it consists in
the matters here in after described and pointed out in the appended claims.
In the accompanying drawings illustrating my invention.
Figure 1. is a perspective view of a horse collar embracing the several features of
construction, constituting my invention.
Figure 2. is a horizontal section of one of the collar pads taken through the
connection by which the hame-tug is connected therewith.
Figure 3. is a perspective view of a swivelled block by which the connection
between the collar pad and tug is made.
Figure 4. is a face view of the adjustable yoke shown in figures 1. and 2.
Figure 5. is a detail side view of the joint connecting the two parts, or
composing the yoke shown in Figure 4.

figure 4.

their
In the said drawings A. A. are the collar pads which are suitably shaped upon
inner surfaces to fit the shoulders of a horse; B. B. are the traces and B B tugs by
which the iraces are connected with the collar pads. As far as the other features of
the invention are concerned, the pads A. A. may be constructed in any desired, or
preferred manner, a preferable form thereof being herein illustrated in which they
consist of thin metal plaies A¹ A¹ to the outer surfaces of each of which is attached
by rivets or screws, a vertically arranged bar A employed for the purpose of giving
convenient means of
the necessary stiffness to the plates A¹ A¹ and to afford a
connecting the hame-tugs and other parts therewith.
C
As a preferred means of connecting the said tugs B₁ with the collar pads, a
swivelled connection between the parts is employed, consisting of a block C. provided
with a shank c which passes through and is adapted to rotate in an aperture a. in the
bar A2 of the collar. In constructing the said block C. it will preferably be
connected with the bar A2, by inserting the shank & through the bearing aperture a,
and then upsetting a head upon the end of the said shank, before the plate A' is
attached to the inner surface of the said bar A².
The tug B', is connected with the block C. by means of a pivot pin C inserted
vertically through the parts, the end of the tug being, as herein shown forked to
embrace the said block C, the joint between the tugs and the collar pads formed as
described, obviously allows said pads to rotate freely in a horizontal plane and also to
rotate about an axis at right angles with their inner and outer flat surfaces, thus
allowing the pads to accurately adjust themselves to the shoulders of the horse during
all movements of the latter. The ends of the tugs B', adjacent to the collar pads are
bent or curved inwardly as more clearly shown in Figure 2. the employment of the
vertical pivot c obviously preventing the rotation of the tug in such manner as to
allow the outer part of the tug to fall, so that the latter is constantly sustained in a
horizontal position with the traces free from the shoulders of the horse, as will be
readily understood by an inspection of the drawings, Figures 1. and 2.
D. is the metal yoke connecting the pads A. A. to hold the latter from spreading
apart and in proper positions against the horse's shoulders. The said yoke D. is
connected at its ends by universal ends with the collar pads, so that it may depend or
swing freely beneath the horse's neck, and will hold the collar-pads from spreading
apart while at the same time allowing perfect freedom of movement therein.
Said yoke is preferably made adjustable in such manner that the distance between
its ends may be changed, thereby enabling the distance apart at which the pads ard
held to be varied to fit the shoulders of the horse.-When the particular form of
joints between the tugs and collar pads, illustrated in Figures 1. 2. and 3. and above
described, is used, the blocks C. may be conveniently provided with upwardly
turned hooks C2, adapted to engage eyes d. d. formed in the ends of the yoke I).
This construction obviously affording a universal joint or connection between the
paris allowing a free movement of one pad with reference to the other pad, while at
the same time permitting the yoke to be easily disconnected from the pads when
. desired.
In one convenient form of the yoke D. shown in figures 1. 2. 4. and 5. said yoke
consists of the bars D' D'arranged to overlap at the middle of the yoke and provided
at their adjacent ends with downwardly extending arms d' d', through the ends of
which is inserted a pivot pin d, by which the said bars D¹ D¹, are connected, the
bars being held in a desired relative position by a clamping serew, or other equivalent.
device applied to the overlapping parts of the said bars D¹ to hold the outer ends
of the latter rigidly in a desired position.
As herein shown the contact faces of the arms are corrugated, or serrated as
indicated at d³, (figures 1. and 5.) and a bolt D2 provided with a thumb nut d'-is
employed for clamping the corrugated surfaces together, one of the bars D', being
provided with a slot d, concentric with the pivot d², to allow the required movement
of the outer ends of the bars in adjusting them.
Another construction in the yoke whereby the same general result is obtained is

page_text: illustrated in Figures 6. and 7. In this instance the two bars D¹ D', composing the
voke are provided with straight overlapping parts and are united by means of
holis D³ ³ which are provided with thumb nuts de d. One of said bolts, being
inserted through an aperture 7, in the end portion of one of the bars D', and through
a slot D. 4. in the opposing part of the other bar, this construction obviously enabling
the outer ends of the bars to be placed and held at a greater or less distance apart, in
a familiar manner.
A further improvement under this invention consists in making the tug 13, with
slots B³, grooves B, and providing a cotter B³, to fit through the said slots and
through an eye in the trace B. as shown more particularly in Figures 8. and 9.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what claim is :-
1. The combination with two independent collar pads and tugs connected with
the pads, of a depending metal yoke connected at its ends with both the pads and the
tugs by universal joints, substantially as described.
2. The combination, with two independent collar pads of a depending yoke
connected at its ends with the pads by universal joints, said yoke consisting of two
overlapping bars D¹ D', provided with arms connected at the ends of said arms,
and means for clamping the bars together, substantially as described.
8. The combination with two independent collar pads. A rigid yoke joining the
pads and tugs connected with the pads of joints for connecting the tugs with the pads
consisting of blocks supported upon the pads with their axes of rotation at right
angles with the planes of the pads, said blocks being connected with the tugs by
vertical pivois substantially as described.
4. The combination with two independent collar pads each consisting of a meial
har A, provided with a bearing-aperture and a plate secured to the inner face of the
bar, of fugs for joining the traces with the pads and blocks connecting the hame iugs
with the pads, said blocks having shanks inserted and adapted to rotate in the said
bearing aperture and being connected with the tugs by vertical pivots, substantially
as described.
5. The combination with two independent collar pads of a depending yoke for
connecting the pad provided with apcriures or eyes at its ends, iugs for connecting
the traces with the pads, and blocks pivotally connected with the pads and tugs, said
blocks being provided with hooks for engaging the ends of the yoke, substantially as
described.
6. The combination with horse collars constructed in accordance with the
improvements herein set forth of tugs having grooves slots and cotters or keys
substantially as set forth.
