Improvements in Stocks or Holding Appliances for the Performance
of Surgical Operations on Horses.
I, EDOUARD ADOLPHE VINSOT, Veterinary Surgeon, residing at No. 44. Ruc du
Grand Cerf, Chartres, Department of Eure-et-Loir, French Republic do hereby
declare the nature of this invention to be as follows:-
-
The chief part of this invention consists of a main framing with two axles
capable of pivoting and resting at their two longitudinal ends in bearings form-
ing part of metal legs fixed in the ground, in such a manner that the force
exerted by two men, each bearing upon a lever fixed to the top of said framing,
is capable of bringing into a recumbent position a horse fastened to a table
fixed to the said main framing.
Figure 1 is a perspective view in elevation of the general arrangement of the
apparatus in a state of rest.
Figure 2 is an end view of this apparatus when the veterinary surgeon is per-
forming surgical operations upon a horse.
This apparatus is shown in Figure 1 in a state of rest before the arrival of the
horse which is to undergo certain surgical operations. The main framing con-
sists substantially of a top piece a the two ends of which are provided with a
frame of double T iron, one b, of which carries the operating windlasses, and
one of the pivots rocking in a bearing having fixed feet c, c¹. The other
frame d, also composed of double T iron, holds at its lower end the chain for
the fastenings for the feet of the horse, and at its centre of gravity it holds the
pivot of oscillation the end of which rests, like the pivot b', in a bearing
mounted on feet e, e, fixed in the ground.
As the whole of the main framing rests upon the two axles, the result
is that when either one of the branches f, or the branch f¹, fixed to the top
piece a, is acted upon, the apparatus is caused to pivot and can be moved into
the position shown in Figure 2. By pulling the large lever 9, the apparatus
can be easily brought back into the position shown in Figure 1.
The mode of operation of the apparatus takes place substantially in the follow-
ing manner: The horse is brought near to the apparatus arranged as shown in
Figure 1, and in order to allow the animal to enter inside the same, the bar his
raised by means of the lever ¹ and the bar h can be turned along its axis ².
then the bar h is moved back into its place, and then the horse having one of its
flanks resting against the cushions ij of the operating table, and the other flank
tightly held by the bar h, the operator can then control part of its movements.
Nevertheless use is made of the chain provided with five fastenings for the
purpose of ensuring the complete immobility of the horse. By turning the
crank handle upon which a ratchet wheel and its pawl operate in the ordinary
way, it is possible by means of the pinion m and the wheel to rotate the shaft o
which then serves to completely stretch the chain k.

page_text: The immobility of the upper part of the horse is secured by means of the bar p
and its two hooks which have two grooved pulleys in which passes a chain
whose fixed end is at a', and its other end which is fixed to the shaft q, winds
itself upon the latter as soon as the crank r is operated of which the axles for
the small pinions and for the toothed wheel t are carried in one of the faces of
the main framing.
The body of the horse being thus rendered incapable of movement, it is
sufficient for two men to operate the levers f, f¹, in order to bring the apparatus
from its upright position into a horizontal position, when it will be easy for the
veterinary surgeon to perform his surgical operations.

I, EDOUARD ADOLPHE VINSOT, Veterinary Surgeon, residing at No. 44, Rue du
Grand Cerf, Chartres, Department of Eure-et-Loir, French Republic, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
-
The chief object of this invention consists of a main framing with two axes
capable of pivoting and resting at its two longitudinal ends in bearings form-
ing part of metal legs fixed in the ground, in such a manner that the force
exerted by two men, each bearing upon a lever fixed to the top of said framing,
is capable of bringing into a recumbent position a horse fastened to a table
fixed to this said main framing.
Referring to the drawings filed with my Provisional Specification: —
Figure 1 is a perspective view in elevation of the general arrangement of the
apparatus in a state of rest.
Figure 2 is an end view of this apparatus when the veterinary surgeon is per-
forming surgical operations upon a horse.
This apparatus is shown in Figure 1 in a state of rest before the arrival of the
horse which is to undergo certain surgical operations. The main framing con-
sists substantially of a top piece a the two ends of which are provided with a
frame of double T iron, one b, of which carries the operating windlasses, and
one of the pivots b¹ rocking in a bearing having fixed feet c, c¹. The other
frame d, also composed of double T iron, holds at its lower end the chain for
the fastenings for the feet of the horse, and at its centre of gravity it holds the
pivot of oscillation & the end of which rests, like the pivot 6', in a bearing
mounted on feet e, el, fixed in the ground.
As the whole of the main framing rests upon the two axles b', d, the result
is that when either one of the branches f, or the branch f, fixed to the top
piece a, is acted upon, the apparatus is caused to pivot and can be moved into
the position shown in Figure 2. By pulling the large lever g, the apparatus
can be easily brought back into the position shown in Figure 1.
The mode of operation of the apparatus takes place substantially in the follow-
ing manner: The horse is brought near to the apparatus arranged as shown in

page_text: Figure 1, and in order to allow the animal to enter inside the same, the bar his
raised by means of the lever h¹ and the bar h can be turned along its axis h²,
then the bar is moved back into its place, and then the horse having one of its
flanks resting against the cushions i, j, of the operating table, and the other flank
tightly held by the bar h, the operator can then control part of its movements.
Nevertheless use is made of the chain provided with five fastenings for the
purpose of ensuring the complete immobility of the horse. By turning the
crank handle upon which a ratchet wheel and its pawl operate in the ordinary
way, it is possible by means of the pinion m and the wheel n to rotate the shaft o
which then serves to completely stretch the chain k.
The immobility of the upper part of the horse is secured by means of the bar p
and its two hooks p', p, which have two grooved pulleys in which passes a chain
whose fixed end is at a', and its other end which is fixed to the shaft g, winds
itself upon the latter as soon as the crank is operated, of which the axles for
the small pinions and for the toothed wheel t are carried in one of the faces of
the main framing.
The body of the horse being thus rendered incapable of movement, it is
sufficient for two men to operate the levers f, f¹, in order to bring the apparatus
from its upright position into a horizontal position, when it will be easy for the
veterinary surgeon to perform his surgical operations.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
—
(1) An improved stock or holding appliance for horses composed of a top
piece a, and of two frames b, d, capable of rapidly pivoting on two axles b', d²,
when the vertical levers f, fi, are actuated, in such a manner that the apparatus
as shown in Figure 1, shall be able to assume the horizontal position shown in
Figure 2, as set forth.
(2) An improved stock or holding appliance for horses constructed and
arranged substantially as herein before described and shown.
