AN ESCAPE FOR HORSES, BY MEANS OF WHICH THEY MAY DISENGAGE THEM- SELVES FROM THEIR HALTERS WHEN ENTANGLED THEREIN
Year: 1792

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
JENNER, of Burbage; in the County of Wilts, Gentleman, send greeting.
WHEREAS the King's most Excellent Majesty, by Letters Patent under
the Great Seal of Great Britain, bearing date the Eighteenth day of April,
One thousand seven hundred and ninety-two, gave and granted unto me, the
said Stephen Jenner, my executors, administrators, and assigns, His Majesty's
special licence, full power, sole privilege and authority, for me, the said
Stephen Jenner, my executors, administrators, and assigns, and every of them,
by myself and themselves, or by my and their deputy or deputies, servants or
agents, or such others as I, the said Stephen Jenner, my executors, admi-
nistrators, or assigns, should at any time agree with (not exceeding the number
of five) and no others, from time to time and at all times thereafter during the
term of years therein expressed, to make, use, and vend my Invention of
"AN ESCAPE FOR HORSES, BY MEANS OF WHICH THEY MAY DISENGAGE THEM-
SELVES FROM THEIR HALTERS WHEN ENTANGLED THEREIN," within that part of
His Kingdom of Great Britain called England, Dominion of Wales, and Town
of Berwick-upon-Tweed, in such manner as to me, the said Stephen Jenner,
my executors, administrators, and assigns, or any of them, should, in my or
their discretions seem meet, to have, hold, and enjoy the said licence, power,
privilege, and advantage, to me, the said Stephen Jenner, my executors,
administrators, and assigns, for the term of fourteen years from the date of
the said Letters Patent, next and immediately ensuing, and fully to be complete
and ended, according to the Statute in that case made and provided; in
which said Letters Patent is contained a proviso that if I, the said Stephen

page_text: Jenner, should not particularly describe and ascertain the nature of my said
Invention, and in what manner the same is to be performed, by an instrument
in writing under my hand and seal, and cause the same to be inrolled in His
Majesty's High Court of Chancery within one calendar month next and imme-
diately after the date of the said Letters Patent, that then the said Letters
Patent, and all liberties and advantages whatsoever thereby granted, should
utterly cease, determine, and become void, anything therein-before contained to
the contrary thereof in anywise notwithstanding, as in and by the said Letters
Patent, relation being thereunto had, will more fully and at large appear.
NOW KNOW YE, .that I, the said Stephen Jenner, in pursuance of the
said proviso in the said Letters Patent contained, do hereby describe and
ascertain the nature of my said Invention, and the manner in which the same
is to be performed, as follows; that is to say :-
By the annexed Drawing, A exhibits the top view of the rail of the manger,
in which rail is comprised the escape; B, the front view of the rail; C, the
under view of the rail; D, D, are parts of the halter which hang below the
rail of the manger; E, E, are parts of the halter which are above the rail of
the manger, and lead to the head of the halter at U; F, F, are short levers
which work on pins or hinges at I, I. I have mentioned pins or hinges, as
either will answer. If hinges be used, they may be fastened to the rail and
thin parts of the levers F, F, which are shewn and explained by H, H, but
in the Drawing annexed I have shewn the levers working on pins. G, G, are
the ends of the levers F, F; they are made thin to fit into the under part of
the rail to give it strength, and prevent its being torn off by the horse when
he hangs back or looks over either side of the stall. H, H, are thin parts of
the leavers F, F, through which go the pins I, I, on which the levers work.
I, I, are pins on which the levers work. The dotting shewn in the under
view of the rail C describes the parts of the pins that go through the rail and
thin parts of the levers. K, K, are wheels or oblique surfaces. The dotted
parts of the wheels are hidden in the rail and levers. L, L, are pins on which
the wheels K, K, work. If only oblique parts be used, they may be fastened to
the rail by a few screws, M, M, are openings on the top of K, K, and parts of
the levers F, F, for the halter's reins to run in. N, N, are the lower parts of
the openings at the side of K, K, by which the halter is discharged from the
rail by pressing down on the levers F, F, which give way. 0, 0, are the
upper parts of the levers F, F, which are fitted into the top of the rail A, to
prevent the horse's raising the levers with his teeth, and is made heavier than
F, F, to keep it in its proper place and counterbalance the halter and weight
at the end of it on either side after the halter's rein has been discharged in

page_text: the opposite; for after one rein is discharged the other does not always lie on
the wheel as when they are both in the rail; the dots shew the concealed parts
of the leavers that are let into the rail and holes R, R. The ends of the levers,
as shewn by 0, 0, may be considerably shortened, or even entirely taken away,
and a spring substituted'; but as springs are liable to rust, and break through
bad temper or flaws, from the trials I have made, I should certainly recommend
long levers, and in some instances a weight. P, P, are the under parts of the
levers F, F, as shewn in the under view of the rail C. Q, Q, are holes,
through which the halter's reins pass on the back parts of the levers F, F, up
to M, M. R, R, are holes, as seen in the view of the rail C, into which the
ends of the levers are fitted, and through which dust may be cleaned from the rail
that may happen to get in at the upper parts of the levers. S, S, are knobs
or weights at the ends of the halter's reins D, D. T, T, are knobs at the end
of the knobs or weights S, S. U is the head of the halter. V, V, are the
concealed ends of the levers, as shewn by the dotting. These ends are made
thin to fit into the rail to prevent its being torn off by the horse when he
hangs backwards or looks over either side of the stall. G, G, is the under
view of the thin parts of the levers, which are shewn by V, V. Through the
holes Q, Q, the halter's reins move as freely by the weights or knobs S, S, as
in the common mode of fastening; if the horse hangs backwards, the weights
are merely drawn up to the bottom of the rail C; if the halter be drawn side-
ways by the horse's turning or looking over either side of the stall, the one rein
is slack while the other is strained in the upper part of the opening M; but
if the horse gets his foot over either rein, it is, by his hanging backwards or
plunging, immediately drawn to the lower part of the opening at N, over the
wheel or oblique part K, down upon the lever F, which gives way, and the
halter is discharged, and the horse freed from his dangerous situation with
respect to that one rein, but still secured to the rail by the other, unless a
similar accident, which never or rarely occurs during the absence of the groom.
These principles may be reduced to a smaller compass, and put in such a form
as to be affixed to any rail already in use; but the principles being exactly the
same as this I have described, a Drawing and explanation I conceive to be
unnecessary. This machine, I trust, will remedy every inconvenience which
has been complained of, without creating others.
In witness whereof, I, the said Stephen Jenner, have hereunto set my
hand and seal, the Thirtieth day of April, in the year of our Lord One
thousand seven hundred and ninety-two.
STEPHEN (LS.) JENNER.
