Year: 1861

page_text: LETTERS PATENT to Henry Sagar, of Broughton, Manchester, for the
Invention of "IMPROVEMENTS IN MACHINERY FOR FINISHING PATENT TRACING
CLOTH AND OTHER WOVEN FABRICS."
Sealed the 9th July 1861, and dated the 15th January 1861.
PROVISIONAL SPECIFICATION left by the said Henry Sagar at the
Office of the Commissioners of Patents, with his Petition, on the
15th January 1861.
I, HENRY SAGAR, of Broughton, Manchester, do hereby declare the nature
of the Invention for "IMPROVEMENTS IN MACHINERY FOR FINISHING PATENT
TRACING CLOTH AND OTHER WOVEN FABRICS," to be as follows:-
This Invention has for its object improvements in machinery for finishing
Patent tracing cloth and other woven fabrics. Heretofore three bolls or
rollers have been employed in finishing Patent tracing cloth, two smooth metal
rollers or bolls having a paper roller or boll between them. The fabric has
been conducted between the paper roller or boll, and the first metal roller or
boll, then partly around the paper roller or boll, and then between it and the
second metal roller or boll, such second metal roller or boll being kept heated.
The surface speed of the second metal roller has been somewhat greater than
that of the first metal roller, the driving of the two metal rollers or bolls being
by the same intermediate wheel driving both the first and second metal
rollers.
Now the object of the present Invention is to drive the second metal roller
or boll at a far higher surface speed in relation to the surface speed of the
first metal roller or boll than could be obtained by the old arrangement. For
this purpose it is preferred, in place of the two rollers being driven by the

page_text: same cog wheel gearing with cog wheels on the axes of the two metal rollers
or bolls, as heretofore, to employ two cog wheels on the same axis, one to
drive the first metal roller, and the other to drive the second metal roller, by
which means the second roller may be driven at a far higher relative surface
speed as compared with the surface speed of the first metal roller or boll than
beretofore. By these means a better or higher finish is obtained to the
tracing cloth or other fabrics.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Sagar in the Great Seal Patent Office on the
15th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
SAGAR, of Broughton, Manchester, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of January, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Sagar, Her special licence that I, the said Henry Sagar, my
executors, administrators, and assigns, or such others as I, the said Henry
Sagar, 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, tho
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR FINISHING PATENT TRACING CLOTH AND OTHER WOVEN FABRICS,"
upon the condition (amongst others) that I, the said Henry Sagar, 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 per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar mouths next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Henry Sagar, do hereby declare the
nature of the 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, that is to say:-
This Invention has for its object improvements in machinery for finishing

page_text: Patent tracing cloth and other woven fabrics. Heretofore three bolls or
rollers have been employed in finishing Patent tracing cloth, two smooth metal
rollers or bolls having a paper roller or boll between them. The fabric has
been conducted between the paper roller or boll and the first metal roller or
boll, then partly around the paper roller or boll, and then between it and the
second metal roller or boll, such second metal roller or boll being kept
heated. The surface speed of the second metal roller has been somewhat
greater than that of the first metal roller, the driving of the two metal rollers
or bolls being by the same intermediate wheel driving both the first and
second metal rollers.
Now the object of the present Invention is to drive the second metal
roller or boll at a far higher surface speed in relation to the surface speed of
the first metal roller or boll than could be obtained by the old arrangement;
for this purpose it is preferred in place of the two rollers being driven by the
same cog wheel gearing with cog wheels on the axes of the two metal rollers
or bolls, as heretofore, to employ two cog wheels on the same axis, one to
drive the first metal roller, and the other to drive the second metal roller, by
which means the second roller may be driven at a far higher relative surface
speed as compared with the surface speed of the first metal roller or boll than
heretofore. By these means a better or higher finish is obtained to the
tracing cloth or other fabrics.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews an end elevation, and Figure 2 a back elevation of a
machine arranged to work according to my Invention. a, a, is the framing
of the machine; b is the roller from which the fabric to be finished passes to
the rollers or bolls of the machine; c is the roller on to which the cloth is
wound as it comes from the machine, and such winding is by an endless
driving band or strap d on the pullies e and f, such band or strap readily
slipping on the pullies, so as not to draw the fabric faster than it is delivered
from the rollers or bolls of the machine; g is the lower or first metal boll or
roller; his the paper boll or roller; and i is the second metal roller or boll.
The machinery receives motion from a steam engine or other power, which
by preference, as heretofore, gives motion to the shaft or axis i¹ of the roller
or bolli. On the other end of the axis i¹ of the roller or boll i there is a cog
wheel j, by which motion is communicated to the metal boll or roller g, as
hereafter explained. I would here state that the arrangement or combination

page_text: of the machinery above mentioned and described is the same as that heretofore
employed, but in place of the intermediate cog wheel k, which receives motion
from the cog wheel j, giving motion, as was formerly the case to the cog
wheel on the shaft or axis of the metal boll or roller g, such metal roller or
boll g receives motion from the cog wheel 1, which is on the same stud or
fixed axle m as the cog wheel k, the cog wheel l and the cog wheel & being.
connected together. By thus employing an additional wheel to give motion
to the wheel n on the axis of the boll or roller g, in place of the wheel k being
used for that purpose, the surface speed of the metal boll or roller i exceeds
in its surface speed that of the roller or boll g, and the extent of variation in
respect to the surface speed of these rollers or bolls may be varied by changing
the wheels.
In
Figure 3 shews an end elevation, and Figure 4 a back elevation, of another
machine having change wheels, so that the relative speeds of the surfaces of
the metal rollers or bolls g and i may at different times be varied.
this arrangement the intermediate cog wheel k may give motion to the cog
wheel x which is on the shaft or axis of the metal roller or boll g, in which
case this machine would be worked precisely as heretofore, and to which
arrangement or combination I make no claim; but in addition to the cog
wheel k there are two other cog wheels and l' on the same stud or axis,
either of which may be employed to give motion to the metal roller or boll g,.
according as they are respectively geared with their cog wheels n, n', on the
shaft or axis of the metal roller or boll g. In this arrangement the cog.
wheels k, l, and l', are connected together, and turn on the fixed axis or
stud m.
The cog wheels x, n, and n³ are capable of being slid into and out
of gear with their respective wheels k, l, l', as is well understood. In
those machines where an additional paper boll or roller and an additional
metal boll or roller are employed, the mode of driving above described,
according to my Invention is resorted to by me, that is to say, in place of
using the same intermediate cog wheel to gear with the cog wheel which is
on the first metal roller or boll, as well as with the cog wheel on the second
metal roller, I cause a second intermediate cog wheel to be used, and to gear
with the cog wheel on the first metal roller or boll, so that the middle metal
roller or boll may be driven at as much greater surface speed over the surfaco
speed of the first metal boll or roller, as may be desired.
Figure 5 shews a side elevation, and Figure 6 a back elevation, of a machine
having an additional paper boll or roller and an additional metal roller or boll,
in fact, a double machine, as the metal boll or roller i in this arrangement
acts as the second metal roller or boll to the other two metal rollers or bolls aud

page_text: the two paper bolls or rollers. The machine shewn in these Figures of the
Drawings is similar to those heretofore employed when using five rollers, two
paper rollers, and three metal rollers, but in the arrangement shewn in these
Figures the driving of the metal rollers is, according to my Invention, as when
using only three rollers. In this arrangement g is the first or lower metal
roller or boll; h is the paper roller or boll; and i is the second metal roller or
boll which, as in the former arrangements, receives motion from a steam
engine or other power as heretofore. On the shaft or axle of this boll or
roller i is a cog wheel j, which takes into and drives the intermediate wheel k,
which is on a stud or fixed axis m, as is above described in respect to the
other arrangements, Figures 1 and 2, and Figures 3 and 4. In place of tho
intermediate cog wheel k giving motion to the cog wheel on the axis or shaft
of the first metal boll or roller g, the additional wheel is used, which is con-
nected to the cog wheel k, and turns therewith. The cog wheel / gives motion
to the cog wheel n on the shaft or axis of the first or lower metal roller or
boll g, as before explained. The cog wheel j also gives motion to the cog
wheel on the fixed axis or stud m', on which there is another cog wheel l'
affixed to the cog wheel k', and this cog wheel l¹ gives motion to the cog
wheel n' fixed on the axis or shaft of the other metal roller or boll g', so
that the additional roller or boll g' and the additional paper roller or boll h¹
are put in a like relation to the metal boll or roller i, as are the bolls or
rollers g and h. In Figures 5 and 6 the roller b, from which the fabric to be
finished passes to the machine, and also the roller c for receiving the fabric
when it has passed through the machine, are omitted; they, however, are to
be as heretofore.
Having thus described the nature of my said Invention, and the manner
of performing the same, I would have it understood that what I claim is, the
communicating motion to the rollers or bolls of machinery for finishing Patent
tracing cloth and other woven fabrics, as herein described.
In witness whereof, I, the said Henry Sagar, have hereunto set my
hand and seal, this Tenth day of July, in the year of our Lord One
thousand eight hundred and sixty-one.
