IMPROVEMENTS IN TURNING-OFF. Seaming, and Stitching MACHINES
Year: 1875

page_text: LETTERS PATENT to William Campion, senior, of Snienton, in the
County of Nottingham, for the Invention of "IMPROVEMENTS IN
TURNING-OFF. Seaming, and Stitching MACHINES.”
Sealed the 31st August 1875, and dated the 9th June 1875.
PROVISIONAL SPECIFICATION left by the said William Campion at
the Office of the Commissioners of Patents, with his Petition, on
the 9th June 1875.
I, WILLIAM CAMPION, senior, of Snienton, in the County of
Nottingham, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN TURNING-OFF, SEAMING, AND STITCHING MACHINES," to be as
follows:-
In manufacturing machines for turning-off, seaming, and stitching it
has hitherto been usual to employ a hinged needle bolt. My Invention
consists in substituting therefor a straight bolt, either round or other
shape, in section, sliding in a bearing bracket capable of adjustment
vertically to set it to the inclination of the points. The bolt carries arms
capable of adjustment upon it, which clip an excentric which operates

page_text: the bolt. For seaming I rise and fall the bolt and bracket together by
means of two toothed wheels and a cam.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Campion in the Great Seal Patent
Office on the 9th December 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CAMPION, senior, of Snienton, in the County of Nottingham, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of June, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Campion, senior, Her special
licence that I, the said William Campion, senior, my executors, admini-
trators, and assigns, or such others as I, the said William Campion,
senior, 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
"IMPROVEMENTS IN TURNING-OPF, SEAMING, AND STITCHING MACHINES," upon the
condition (amongst others) that I, the said William Campion, senior, 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 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Campion, senior, 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 following statement, reference being had to the accompanying
Drawing forming a part of this Specification :-
In manufacturing machines for turning-off, seaming, and. stitching it

consists in substituting therefor a straight bolt, either round or other
shape, in section, sliding in a bearing bracket capable of adjustment

operates the bolt. For seaming I rise and fall the bolt and bracket

vertically to set it to the inclination of the points.
The bolt carries
arms capable of adjustment upon it, which clip an eccentric which
operates the bolt. For seaming I rise and fall the bolt and bracket
together by means of two toothed wheels and a cam.
DESCRIPTION OF THE DRAWING.
Figure 1 shews in plan a turning off, seaming, and stitching machine
embodying my improvements; Figure 2 is a side view shewing part of
the same machine; and Figure 3, a side view of the double cam which
operates the racking lever and loop hook.
Instead of an hinged needle bolt heretofore employed I substitute a
straight bolt A, either round or other shape in section, sliding in a
bearing bracket B supported intermediately of its length by an axle B',
the bolt being capable of adjustment vertically by means of a set screw
and nut B² to set it to the inclination of the points C. The bolt carries
arms D, D', capable of adjustment upon it, which clip an excentric D³
which operates the bolt. The racking lever E and the sliding and
rocking hook lever F are operated by the double cam G, seen in plan at
Figure 1, and reverse side views at Figures 2 and 3. The rest of the
machine is of the usual construction, and when employed for seaming
fabrics the needle bolt and bracket are caused to rise and fall together by
two toothed wheels and a cam, the needle passing through a loop on one
of the points C at one stitch, and then clear above the loop the next
stitch alternately.
In witness whereof, I, the said William Campion, have hereunto
set my hand and seal, this Eighth day of December, in the year
of our Lord One thousand eight hundred and seventy-five.
Witness,
H. W. GOUGH, C.E.,
Nottingham.
