CERTAIN IMPROVEMENTS ON INSTRUMENTS FOR BLEEDING HORSES AND OTHER ANIMALS
Year: 1828

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WEISS, of the Strand, in the County of Middlesex, Surgical Instrument
Maker, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth
did, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twenty-sixth day of January, in the eighth year of
His reign, give and grant unto me, the said John Weiss, His especial licence,
that I, the said John Weiss, my executors, administrators, and assigns, and
such others as I, the said John Weiss, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time
and at all times therein mentioned, should and lawfully might make, use,
exercise, and vend, within England, Wales, and Town of Berwick-upon-
Tweed, my Invention of "CERTAIN IMPROVEMENTS ON INSTRUMENTS FOR BLEEDING
HORSES AND OTHER ANIMALS;" in which said said Letters Patent there is con-
tained a proviso, that I, the said John Weiss, shall cause a particular descrip-
tion of the nature of the said Invention, and in what manner the same is to
be performed, to be inrolled in His Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part

page_text: recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that, in compliance with the said proviso, I, the sail
John Weiss, do hereby declare that the nature of my said Invention, and
in what manner the same is to be performed, are particularly described and
ascertained in and by the four Sheets of Drawings hereunto annexed, and by
the following description thereof (that is to say):
Without attempting to particularize my own Inventions or improvements,
or without any attempt to distinguish my Inventions or improvements from
such parts and things as have been before invented, made known, and used by
others in the construction of spring fleams.
I, the said John Weiss, shall in the first place describe and explain in a
general manner the several spring fleams represented in the aforesaid annexed
Sheets of Drawings; and in the second place, after such general description
of the spring fleams therein represented, without any particular reference to
my own Inventions or improvements, I, the said John Weiss, shall expressly
ascertain and limit my claim under the herein-before in part recited Letters
Patent to the several particulars upon which my said Inventions or improve-
ments are founded.
In the first place, Sheets 1, 2, 3, and 4 represent four kinds of spring
fleams.
Sheet 1, Figure 1, represents the spring fleam with the spring secured by
the catch; Figure 2, with the spring released from the catch; and Figure 3
is a back view of the spring fleam. In these and in the whole of the Figures
in the annexed Sheets of Drawings the same letters indicate the same part in
each particular kind of spring fleam.
In Sheet 1 the spring fleam consists of a plate of metal or other material
marked A, having holes drilled or otherwise made in it for the reception of the
several screws and rivets exhibited in the Drawing, as also a rectangular
orifice B for the admission of the catch C. To this plate is attached a
fleam D, a main spring E, a small spring F, a thumb piece G, and a catch C.
The fleam D is moveable on a centre m, and the back part of the catchi C
represented in Figure 3 is a lever moveable on a fulcrum at n, having a spring
beneath the part marked k, to keep the catch in the position shewn in
Figures 1 and 2, to keep the main spring E as near as possible to the plate
without impeding its action. An aperture is sometimes made, and the thread
part of a screw is passed from the back of the plate into the main spring E,
such aperture being of the shape represented at o, Figures 2 and 3, the head
of the screw Figure 8 being marked p. The action of this spring fleam is

page_text: very simple. The spring E having been brought from the position as
represented in Fig. 2 to that exhibited in Fig. 1, that part of the lever
marked-k is depressed; this relcasos the spring from the catch, and causes it
to strike the fleam with sufficient force to make the requisite incision in the
animal.
Sheet 2, Figure 1, represents the spring fleam with the spring secured by
the catch; Figure 2, with the spring released from the catch; Figure 3, a
front view of the fleam; Fig. 4, a side view of the spring fleam with the
fleam removed; and Figure 5, a back view of the spring fleam. The only
material difference in the construction of the spring fleam represented in this
Sheet of Drawings from that exhibited in the Sheet 1 consists in cutting
away a portion of the under surface of the main spring E to admit the fleam
to be thrown from the wound by the reaction of the small spring F.
Sheet 3, Fig. 1, represents the spring fleam with a lancet or fleam secured
by the catch; Fig. 2, with the lancet or fleam released from the catch; and
Figure 3 is a back view of the spring fleam. The spring fleam represented
in this Sheet of Drawings consists of a plate of metal or other materials
marked A, having holes drilled or otherwise made in it for the reception of
the several screws and rivets exhibited in the Drawings, and for the projecting
part of the catch C. To this plate is attached a lancet or fleam D, a main
spring E, a bent lever F, a thumb piece H, and a catch C, the back part of
which only is represented in Figure 3. The bent lever F and the lancet or
fleam D are moveable in their respective centres m and n, and beneath the
back part of the catch C there is similarly to the spring fleam represented in
Sheet 1 a spring to keep the catch in either of the three holes, more or less,
made in the under part of the bent lever F for its reception. The bent lever,
having been brought from the position represented in Figure 2 to that
represented in Figure 1, is held in that position by the catch. The lever o of
the catch C, being now depressed, releases the bent lever from the catch, and
the spring acting upon that part of the bent lever marked v causes the lancet
or fleam to make a semi-revolution, and make the required incision.
Sheet 4, Figure 1, represents the spring fleam with the hammer or part
that strikes the fleam secured by the catch; Figure 2, with the hammer
released from the catch; and Figure 3, with the hammer secured by the catch,
with the plate A, Figures 1 and 2, removed, to shew the construction of the
fleam. Figure 4 is the front view of the hammer with the fleam removed,
and Figure 5 is à back view of the same. The spring fleam represented in
this Sheet of Drawings consists of a back or handle B, the hammer or part

page_text: which strikes the fleam marked C, the fleam D, the main spring E, three
smaller springs m, n, o, the detent or part F attached to the hammer, the
catch G, the side plates A, and the thumb piece H. The action of this
spring fleam is as follows:-The fleam D and hammer C, being in the position
represented in Figure 2, are drawn back in such manner that one of the
teeth or detents may be secured by the catch G, which is firmly held in its
place by the spring o. The end of the catch being now depressed, the
hammer C is released, consequently it strikes the fleam a blow, which is not
only sufficient to make the necessary incision in the animal, but to throw the
fleam back, by the reaction of the spring m, towards the hammer, near which
it is held by a small spring n, as represented in Figure 2.
I, the said John Weiss, having thus described the several spring fleams exhibited
in the three Sheets of Drawings hereunto annexed, without attempting to
particularize my own Inventions or improvements, or without any attempt
to distinguish my Inventions or improvements from such parts and things
as have before been invented, made known, and used by others in the
construction of spring fleam, do in the second place hereby expressly ascertain
and limit my claim under the herein-before in part recited Letters Patent to
the following particulars (that is to say):
My said Inventions or improvements in the construction of spring fleams
consist,
First, in making the spring fleam in such that tlie fleam is not part of nor
of one piece with the spring, as has heretofore been the case in the construction
of spring fleams (and which rendered them inadequate to the desired object),
but in so making the spring fleam that the spring or the hammer acted upon by
the spring may strike the fleam, thereby assimilating its action to the common
fleam; on which, as is well known, it is customary to strike with a stick or
other material.
Secondly, in introducing a spring or springs to throw by reaction the fleam
from the incision.
Thirdly, in introducing a spring or springs to hold the fleam when it has
been thrown back by such reaction. And,
Fourthly, in giving a semicircular or any other portion of a circular move-
ment of that particular kind represented in Sheet 3 to the fleam.
In witness whereof, I, the said John Weiss, have hereunto set my hand
and seal, this Twenty-fifth day of July, in the year of our Lord Ouc
thousand eight hundred and twenty-eight.
JOHN (L.B.) WEISS.
