IMPROVEMENTS IN SEWING MACHINES
Year: 1870

page_text: LETTERS PATENT--to William Campion, of the Town and County of
2
the Town of Nottingham, Sewing Machine Manufacturer, for the
Invention of "IMPROVEMENTS IN SEWING MACHINES."
Sealed the 8th March 1870, and dated the 11th January 1870.
PROVISIONAL SPECIFICATION left by the said William Campion at:
the Office of the Commissioners of Patents, with his Petition, on
the 11th January 1870..
.
I, WILLIAM CAMPION, of the Town and County of the Town of:
Nottingham, Sewing Machine Manufacturer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN: SEWING. MACHINES," to.
be as follows:-
The Invention has for its object improvements in that class of sewing:
machines known as hand machines, and relates to an improved mode of.
working the shuttle. For this purpose I form the work plate of the.
machine with a suitable race for the shuttle, as heretofore, and I connect

page_text: thereto on the under side suitable undercut guides to receive a slide, to
which the shuttle carrier is attached. This slide is arranged to work to
and fro in a horizontal line, but with its face in a vertical plane, and is
connected by a link or connecting rod to a crank or crank pin mounted
on a disc carried by an axis revolving below the work plate.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Campion in the Great Seal Patent Office
on the 11th July 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CAMPION, of the Town and County of the Town of Nottingham, Sewing
Machine Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of January, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Campion, Her special licence that.
I, the said William Campion, my executors, administrators, and assigns,
or such others as I, the said William Campion, my exccutors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein ex-
pressed, 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
MACHINES," upon the condition (amongst others) that I, the said William
Campion, 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
immediately after the date of the said Letters Patent.

NOW KNOW YE, that I, the said William Campion, 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 thereof, that is to say:

The Invention has for its object improvements in that class of sewing
machines known as hand machines, and relates to an improved mode
of working the shuttle. For this purpose I form the work plate of the
machine with a suitable race for the shuttle as heretofore, and I connect
thereto on the under side suitable undercut guides to receive a slide, to
which the shuttle carrier is attached. This slide is arranged to work to
and fro in a horizontal line, but with its face in a vertical plane, and is
connected by a link or connecting rod to a crank or crank pin mounted
on a disc carried by an axis revolving below the work plate.
And in order that my Invention may be more clearly understood
and readily carried into effect I will proceed, aided by the accompanying
Drawings, more fully to describe the same.
Figure 1 is a longitudinal section through parts of a shuttle sewing
machine having my Invention applied thereto, and Figure 2 is a
sectional elevation at right angles to Figure 1, and taken on the
line 1, 1, thereof.
.
a, a, is the work plate of the machine, which is provided with a
shuttle race b, throat plate c, and sliding covers d, as heretofore, but
according to my Invention I connect thereto on the under side suitable
undercut guides e to receive a slide f, and serve as a race for it. This
slide f, which it will be seen works to and fro in a horizontal line, but
with its face in a vertical plane, has fixed thereto the shuttle carrier g and
is connected by pin joint f' to one end of a link or connecting rod h,
the other end of which is pin jointed to a crank disc i which is fixed on
the end of the shaft or axis j. The work plate a, shuttle race b, and
guides e are all cast in one piece, the race 6 and guides e being finished
by rotating cutters.
I would here remark that I am aware that shuttles have been pre-
viously driven by a crank pin and connecting rod, but heretofore
machines so operated have been more expensive, more difficult to work,
and less compact than when made according to my Invention, but by
the adoption of my improvements a cheap, compact, and easily operated
machine is obtained.
Having thus described the nature of my said Invention, and the

page_text: mode in which I carry the same into effect, I would have it understood
that what I claim is, the novel arrangement and combination of means
for working the shuttle, as herein shewn and described:
In witness whereof, I, the said William Campion, have hereunto
set my hand and seal, this Fourth day of July, in the year of our 5
Lord One thousand eight hundred and seventy.
