Year: 1867

page_text: LETTERS PATENT to William Winter, of Leeds, in the County of York,
Sewing Machine Maker, for the Invention of "IMPROVEMENTS IN SEWING
MACHINES."
Sealed the 20th March 1868, and dated the 24th September 1867.
PROVISIONAL SPECIFICATION left by the said William Winter at the
Office of the Commissioners of Patents, with his Petition, on the
24th September 1867.
I, WILLIAM WINTER, of Leeds, in the County of York, Sewing Machine
Maker, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SEWING MACHINES," to be as follows:-
This Invention relates to means of working or operating the needles and
shuttles or other thread carriers employed in sewing machines, and the
improvements consist in the combination of a bell or boss cam with a plate
cam on the same shaft, and in the application thereof to and arrangement of
levers or other connecting parts for working the said needles and shuttles or

page_text: other thread carriers of sewing machines, whereby a more simple and direct
action is produced on such thread carriers, thus simplifying the working parts
and rendering sewing machines more efficient and durable than heretofore,
also diminishing the cost thereof.
The nature of my. Invention will be clearly understood by reference to
the annexed outline Drawing, where Fig. 1 is a side view and Fig. 2 is a
plan of so much or such parts of a sewing machine as will illustrate my
improvements.
A is the plate cam, and B the boss cam, which are both cast or formed in
one part and fixed on one shaft C. The plate cam is arranged to operate
the lever D, which is connected to and works the needle carrier E, and the
boss cam is arranged to operate a lever G which actuates or drives the
shuttle H.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Winter in the Great Seal Patent Office on the
24th March 1868.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, I, WILLIAM
WINTER, of Leeds, in the Couuty of York, Sewing Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of September, 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 William Winter, Her special licence that 1, the said William Winter,
my executors, administrators, and assigns, or such others as I, the said
William Winter, 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
SEWING MACHINES," upon the condition (amongst others) that I, the said William
Winter, my executors or administrators, by an instrument in writing under my,
or their, or one of their bands and seals, should particularly. describe and ascer-
tain 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

page_text: within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said William. Winter, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof and accompanying Sheet of Drawings (that is to say) :-
This Invention relates to means of working or operating the needles and
shuttles or other thread carriers employed in sewing machines, and the
improvements consist in the combination of a bell or boss cam with a plate cam
on the same shaft, and in the application thereof to an arrangement of levers
or other connecting parts for working the said needles and shuttles or other
thread carriers of sewing machines, whereby a more simple and direct action
is produced on such thread carriers, thus simplifying the working parts and
rendering sewing machines more efficient and durable than heretofore, almost
diminishing the cost 'thereof.
In order that this Invention may be clearly understood I herein give
reference to an accompanying Sheet of Drawings of a sewing machine con-
structed in accordance therewith.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation, partly in section, and Fig. 2 is a plan of the
same.
The general arrangement and action of this machine is similar to others in
ordinary use, which being well known it is not deemed necessary to refer to
all the parts thereof. The particular parts of the machine wherein are shewn
my improvements are as follows:-
The ordinary plate cam A and the bell or boss cam B are both fixed upon
the same shaft C, and may be either cast together or attached one to the
other, as shewn in the Drawings annexed to my Provisional Specification, or
may be formed separate, but fixed on the same shaft, as shewn more clearly
at Fig. 2 of these Drawings. The former is placed or arranged so as to
actuate the lever D which is hinged to the arm of the machine in the usual
manner, and by which reciprocatory motion is given to the needle carrier E
in a vertical direction. The latter actuates the lever G hinged under the bed,
by the action of which the shuttle H is actuated or driven in a horizontal
direction. This lever acts direct on the shuttle carrier or propeller I by
passing through a slot hole formed therein, thus requiring no joints, cotters,
or pins in connecting the parts together, whereby sewing machines are very

page_text: much simplyfied in construction and rendered more efficient and durable,
besides the original costs thereof being greatly diminished.
In witness whereof, I, the said William Winter, have hereunto set my
band and seal, this Twenty-first day of March, One thousand eight
hundred and sixty-eight.
WILLIAM WINTER.
