page_text: LETTERS PATENT to William Winter, of Leeds, in the County of
York, Sewing Machine Manufacturer, for the Invention of "AN
IMPROVED METALLIC DRIVING BELT OR BAND, AND THE MEANS OF MANU-
FACTURING SAME, ALSO THE APPLICATION THEREOF AND OTHER METALLIC
BELTS FOR DRIVING SEWING MACHINES."
Sealed the 25th February 1870, and dated the 30th August 1869.
PROVISIONAL SPECIFICATION left by the said William Winter at the
Office of the Commissioners of Patents, with his Petition, on the
30th August 1869.
I, WILLIAM WINTER, of Leeds, in the County of York, Sewing
Machine Manufacturer, do hereby declare the nature of the said
Invention for "AN IMPROVED METALLIC DRIVING BELT OR BAND, AND THE
MEANS OF MANUFACTURING SAME, ALSO THE APPLICATION THEREOF AND OTHER
METALLIC BELTS FOR DRIVING SEWING MACHINES," to be as follows:-
This improved metallic driving belt consists of a wire or rod of iron,
copper, or other suitable metal flattened at intervals of equal distances
apart sufficiently to be elastic when annealed, portions of the said wire
being left prominent, forming teeth or projections thereon to fit into
teeth or notches formed in the surfaces of the pullies to be used in
connection therewith for driving or communicating motion to different
kinds of machinery. Or instead of projections being formed thereon,

page_text: perforations may be made in flattened wire to fit projections formed on
the pullies to be used therewith.
In the manufacture of such belts or bands I use a pair of hardened
steel rollers, the surface of one or both being formed suitably to leave
the projections or to produce the perforations as may be required, and
for this purpose I employ a furnace in which to heat the wire, and from
which it is drawn out in a heated state by the rollers, and passing
between them it becomes flattened and formed. In some cases I may
flatten wire in the manner stated without first heating it.
Wire thus formed into elastic belts or bands and other metallic belts,
bands, or chains I apply for the driving of sewing machines.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Winter in the Great Seal Patent Office on
the 28th February 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WINTER, of Leeds, in the County of York, Sewing Machine Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of August, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Winter, Her special licence that
I, the said William Winter, my executors, administrators, and assigns,
or such others as I, the said William Winter, my executors, 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
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 IMPROVED METALLIC
DRIVING BELT OR BAND, AND THE MEANS OF MANUFACTURING SAME, ALSO THE
APPLICATION THEREOF AND OTHER METALLIC BELTS FOR DRIVING 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 hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what

page_text: 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 Winter, 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 and accompanying Sheet of Drawings (that is
to say)
:-
This improved metallic driving belt consists of a wire or rod of iron,
copper, or other suitable metal flattened at intervals of equal distances
apart sufficiently to be elastic when annealed, portions of the said wire
being left prominent, forming teeth or projections thereon to fit into
teeth or notches formed in the surfaces of the pullies to be used in
connection therewith for driving or communicating motion to different
kinds of machinery. Or instead of projections being formed thereon,
perforations may be made in flattened wire to fit projections formed on
the pullies to be used therewith.
In the manufacture of such belts or bands I use a pair of hardened
steel rollers, the surface of one or both being formed suitably to leave
the projection or to produce the perforations as may be required, and for
this purpose I employ a furnace in which to heat the wire, and from
which it is drawn out in a heated state by the rollers, and passing
between them it becomes flattened and formed. In some cases I may
flatten wire in the manner stated without first heating it.
Wire thus formed into elastic belts or bands and other metallic belts
or bands or chains I apply for the driving of sewing machines.
This Invention will be readily understood by reference to the
accompanying Sheet of Drawings, wherein Fig. 1 is an illustration
of the metallic driving belt or band manufactured according to the
said Invention shewn in two different views edgewise and flatwise. The
parts marked a shew the wire or rod in the state it is in before being
flattened at the parts marked 6 by being passed between suitably formed
rollers.
Fig. 2 is the side elevation of a machine constructed for the purpose
of manufacturing these belts or bands, and Fig. 3 is a cross section of
the same taken through the line A, B, in Fig. 2, shewing the recesses
or notches formed in the bottom roller C; also that the top roller D is
(in this case) a smooth or even circular periphery. These two rollers

page_text: are geared together by spur toothed wheels E and F, and motion is com-
municated to them by the spur toothed wheel G in gear with the spur
toothed wheel H, which is fixed on the main driving shaft I, on which
are the fast and loose driving pullies J and J', with a fly or balance
wheel K also fixed thereon.
The operation of this machine will be easily understood. The two
rollers C and D being set at a suitable distance apart according to the
thickness the flattened part of the belt or band is required to be made,
when on motion being given to them, and on a wire or rod of iron or
other metal being introduced between them, it will be formed as shewn
in Fig. 1. The parts a having entered the recesses in the roller C are not
acted upon or flattened, as are those parts marked b, which pass between
the even surfaces of the two rollers. In some cases where the wire is of
small diameter and very malleable it may be thus operated upon in a
cold state; but in other cases when the wire or rod is thicker or not so
malleable it is necessary to pass the same through a furnace to be
heated, thence direct into this machine, which must be placed suitable
for the purpose.
It will be evident that belts formed of metal in this manner may be
used for driving various kinds of machinery, the driving pullies being
formed with recesses or notches suitable to receive the projections on the
belt, as shewn at L, Fig. 4.
And it will also be apparent that this kind of belt may be employed
for driving a train of pullies and shafts in the same direction without
the use of intermediates, and they may be either in line or arranged
irregularly or out of line with each other by the application of a plain
pressing or holding pulley, as M, to hold the belt in close contact with
and the projections in the notches of the pulley N.
:
Also it will be seen that notched pullies may be used in the place of
plain pressing pullies, and fixed on shafts requiring rotary motion to
them, and by formning the metallic belt with projections on both sides,
which can be so made by having the roller D recessed same as the
roller C (Figs. 2 and 3), then the same belt may drive a double train or
two rows or series of pullies and shafts.
In conclusion, it will be seen that this kind of metallic driving belt is,
when made sufficiently elastic, very suitable or applicable for the driving
of or giving motion to sewing machines, as well as the various other
classes of machinery to which it may be applied.

page_text: I am fully aware that there are other kinds of metallic driving belts
or chains in use for driving machinery of various kinds; but I am not
aware of any kind of metallic belt, band, or chain having been applied
to the driving or giving motion to sewing machines, for which purpose I
consider the application of any kind of metallic belt, band, or chain a
great benefit and advantage over leather or other flexible material of the
usual kinds employed for that purpose.
Having thus described the nature of my said Invention, and shewn by
Drawings how the same is to be or may be performed or carried into
practical operation, I would have it understood that I do not confine
myself to any details of form, size, or strength of the metallic belt herein
set forth, or the precise means of manufacturing the same as to the
application thereof, as shewn and described herein, or to any special
purpose, neither do I claim the application of other kinds of metallic
driving belts or chains to any purpose except the driving of sewing
machines; but what I do claim is,-
Firstly. The manufacture and use or application of metallic driving
belts from wire or rods, as set forth, illustrated, and described herein.
Secondly. The peculiar means or method of manufacturing same or
any modification thereof, as shewn and described.
Thirdly. The application of such belts or other metallic belts or chains
for driving sewing machines.
In witness whereof, I, the said William Winter, have hereunto set
my hand and seal, this Twenty-sixth day of February, in the
year of our Lord One thousand eight hundred and seventy.
Signed, sealed, and delivered by the
within-named William Winter,
