AN IM, BRANDETUR AD INDRAFTMENG IN THE MANTRACTURE OF MACHINE NEEDLES
Year: 1867

page_text: LETTERS PATENT to George Townsend, of Hunt End, Redditch, in the
County of Worcester, Needle Manufacturer, for the Invention of " AN IM,
BRANDETUR AD INDRAFTMENG IN THE MANTRACTURE OF MACHINE NEEDLES."
PROVISIONAL SPECIFICATION left by the said George Townsend at the
Office of the Commissioners of Patents, with his Petition, on the
3rd October 1867.
I, GEORGE TOWNSEND, of Hunt Eud, Redditch, in the County of Worcester,
Needle Manufacturer, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF MACHINE NEEDLES,"
to be as follows (that is to say):-
This Invention consists, firstly, in making machine needles with three or
more longitudinal grooves instead of two only as at present employed. I prefer
to use three grooves, the third being situate just below the shank of the
needle; the advantage of this third groove is that it receives the sewing
material and ensures the formation of the loop, or to attain the same result
with two grooves only I form the back groove in different depths of sinking.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Townsend in the Great Seal Patent Office on the
3rd April 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TOWNSEND, of Hunt End, Redditch, in the County of Worcester, Maou-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of October, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Townsend, Her special license that 1, the said George
Townsend, my executors, administrators, and assigns, or such others as I,
the said George Townsend, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVEMENT OR IMPROVEMENTS IN THE MANUFACTURE OF MACHINE NEEDLES,"
upon the condition (amongst others) that I, the said George Townsend, by
an instrument in writing under my hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said George Townsend, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol-
lowing statement, reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereto (that is to say) :-
:-
This Invention consists, firstly, in making machine needles with three or
more longitudinal grooves instead of two only as at present employed. I prefer
to use three grooves, the third being situate just below the shank of the
needle; the advantage of this third groove is that it receives the sewing
material and ensures the formation of the loop; or to attain the same result
with two grooves only I form the back groove in different depths of sinking.
Referring to the Drawings hereunto attached the various Figures repre-
sent in elevations and sectious, for the purpose of clearer illustration, my
improvements as applied to machine needles of a large size, and such as aro

page_text: adapted for the manufacture of heavy goods, these improvements are of course
equally applicable to machine needles of smaller sizes.
Figures 1, 2, and 3 represent a machine needle formed as already speci-
fied, with three longitudinal grooves instead of two only, as usually made.
(a) Figure 1 is the third groove, the object of which is to receive the sewing
material and ensure the formation of a loop; Figure 2 is a front elevation,
shewing one of the ordinary grooves (b), Figure 3 being a vertical section for
the purpose of illustrating the contour of the grooves; the depth of sinking
or length of such grooves may be varied if found requisite, and the number of
grooves employed may also be increased if necessary.
Figures 4, 5, and 6 shew another method of forming the grooves of
machine needles, whereby a similar result may be obtained, as by the forma-
tion illustrated in Figure 1. I form the back groove shewn in elevation,
Figure 4, and vertical section, Figure 5, in different depths of sinking as at
(c and d), the number of such undulations being increased if desired; Figure 6
shews the needle in side elevation.
Having thus described the nature of my said Invention, and the manner in
which the same may be carried into effect, I claim, without limiting myself to
the exact details of the parts described and shewn, the formation of machine
needles, either by making the same with three or more longitudinal grooves,
or by forming the back grooves of such needles in varying depths of sinking,
as herein more fully set forth and specified.
In witness whereof, I, the said George Townsend, have hereunto set my
hand and seal, this Second day of April, in the year of our Lord One
thousand eight hundred and sixty-eight.
GEORGE TOWNSEND. (L.B.)
