IMPROVEMENTS IN SEWING MACHINE NEEDLES
Year: 1875

page_text: LETTERS PATENT to William Heath, of Redditch, in the County of
Worcester, Manufacturer, for the Invention of "IMPROVEMENTS IN
SEWING MACHINE NEEDLES."
Sealed the 27th July 1875, and dated the 29th April 1875.
PROVISIONAL SPECIFICATION left by the said William Heath at the
Office of the Commissioners of Patents, with his Petition, on the
29th April 1875.
I, WILLIAM HEATH, of Redditch, in the County of Worcester,
5 Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN SEWING MACHINE NEEDLES," to be as follows, that is to
say:
This Invention refers to an improved form of shank for sewing
machine needles, and it consists in so forming that part of the needle
O that it may be capable of more ready and accurate adjustment in the
needle bar. To effect this I form the shank with a collar or flange at-
the tapered lower end where it adjoins the needle, so that the shank can

page_text: pass a certain distance only into the socket in the needle bar, and thus
becomes self-adjusting, and cannot by any accident be pushed further up
the socket. Thus placed, a set screw or other usual appliance holds the
shank firmly, and consequently the needle also. If desired I form the
shank of any other section than cylindrical to insure the grip of the set 5
screw.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Heath in the Great Seal Patent Office
on the 27th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HEATH, of Redditch, in the County of Worcester, Manufacturer, send

give and grant unto me, the said William Heath, Her special license
that I, the said William Heath, my executors, administrators, and
assigns, or such others as I, the said William Heath, my executors,

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 "IMPROVEMENTS IN
SEWING MACHINE NEEDLES," upon the condition (amongst others) that
I, the said William Heath, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and:
seals, should particularly describe and ascertain the nature of the said

NOW KNOW YE. that T. the said William Heath
de honake dration

page_text: be performed, to be particularly described and ascertained in and by
the following statement, that is to say :-
-
This Invention refers to an improved form of shank for sewing,
machine needles, and it consists in so forming that part of the needle
that it may be capable of more ready and accurate adjustment in the
needle bar. To effect this I form the shank (a), as shewn on the
Drawings hereunto annexed, with a collar or flange (6) formed out of the
solid shank at the tapered lower end, where it adjoins the needle (c), so
that the shank (a) can pass a certain distance only into the socket in the
needle bar, and thus becomes self-adjusting, and cannot by any accident
be pushed farther up the socket. Thus placed a set screw or other usual
appliance holds the shank (a) firmly, and consequently the needle (c)
also. If desired I form the shank (a) of any other section than cylin-
drical to increase the grip of the set screw.
Having thus described the object and nature of my said Invention,
and the manner in which the same is to be carried into effect, I claim,
forming sewing machine needles with a collar or flange formed out of
the solid shank, substantially in manner as herein more fully set forth
and specified.
In witness whereof, I, the said William Heath, have hereunto set
my hand and seal, this 25th day of October, in the year of our
Lord One thousand eight hundred and seventy-five.
