Year: 1859

page_text: LETTERS PATENT to Matthew Curtis, of the City of Manchester, in the
County of Lancaster, Machinist, and John Miller, of Staleybridge, in
the said County, Manager, for the Invention of "IMPROVEMENTS IN
GERMAIN MULES FOR SPINNING COTTON AND OTHER FIBROUS SUBSTANCES."
"
PROVISIONAL SPECIFICATION left by the said Matthew Curtis and John
Miller at the Office of the Commissioners of Patents, with their Peti-
tion, on the 7th February 1859.
We, MATTHEW CURTIS, of the City of Manchester, in the County of Lan-
caster, Machinist, and JOHN MILLER, of Staleybridge, in the said County,
Manager, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN CERTAIN MULES FOR SPINNING COTTON AND OTHER FIBROUS SUBSTANCES,"
to be as follows:-
Our said Invention relates to the spinning mules termed double-decked
mules, that is mules in which the headstock is attached to one carriage, and
the motion from such headstock is communicated not only to the carriage
to which it is attached, but to another which is separate therefrom, and con-
sists in causing motion to be communicated from the tin roller in the carriage

page_text: to which the headstock is attached to the tin roller in the other carriage by
means of a shaft and gearing instead of by bands as heretofore. The like
means are applicable if tin drums are amploved instand of tin rallars
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Matthew Curtis and John Miller in the Great Seal Patent
Office on the 5th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MATTHEW
CURTIS, of the City of Manchester, in the County of Lancaster, Machinist,
and JOHN MILLER, of Staleybridge, in the said County, Manager, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of February, One thousand eight
hundred and fifty-nine, in the twenty-second year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto us, the said
Matthew Curtis and John Miller, our executors, administrators, and assigns,
Her especial license, full power, sole privilege, and authority, that we, the
said Matthew Curtis and John Miller, our executors, administrators, and
assigns, or such others as we, the said Matthew Curtis and John Miller,
our executors, administrators, or assigns, should at any time, agree with, and
no others, from time to time and at all times thereafter during the term of
years 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
CERTAIN MULES FOR SPINNING COTTON AND OTHER FIBROUS SUBSTANCES," upon the
condition, amongst others, that we, the said Matthew Curtis and John
Miller, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, by an instrument in
writing under our hands and seals, or under the hand and seal of one of us,
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 in compliance with the said condition, we, the said
Matthew Curtis and John Miller, do hereby declare that the nature of our
said Invention, and the manner in which the same is to be performed, are
particularly described and ascertained in and by the following statement and
description, reference being had to the accompanying Drawings on one Sheet.

page_text: The several Figures are drawn to a scale of three quarters of an inch to one
foot.
Our said Invention relates to the spinning mules termed double-decked
mules, that is, mules in which the headstock is attached to one carriage, and
the motion from such headstock is communicated not only to the carriage to
which it is attached, but to another which is separate therefrom, and
consists in causing motion to be communicated from the tin roller in the
carriage to which the headstock is attached to the tin roller in the other
carriage by means of a shaft and geering instead of by bands as heretofore.
Like means are applicable if tin drums are employed instead of tin rollers.
In the Drawings Figures 1 and 3 are plan views, and Figures 2 and 4 are
elevations of such parts of a double-decked mule as are sufficient to show
our Invention. Figures 1 and 2 show our improvements as applied to mules
where tin rollers are used; and Figures 3 and 4 to mules where tin drums
are employed. In these respective Figures the carriage to which the head-
stock is attached is marked A, the other carriage B, the tin rollers C, the tin
drums D, the short shafts which support one end of the tin rollers a, and the
shaft which drives the tin drums d. E is a metal pipe used to connect the
one carriage to the other; F are fixings, in each of which is a stud on which
the pulley G rotates. These pullies are used to support the pipes E. The
bevil wheels e are fixed one on each of the short shafts a and geer with the
bevil wheels h fixed on the shaft H. In the fixings I are bearings to sup-
port the shaft H, and in which it rotates. The mitre wheels n are fixed one
on each of the shafts d, and geer with the mitre wheels o fixed on the shaft
K. This shaft passes through and rotates in the pipe E, in which are placed
suitable bearings to support the shaft. When motion is communicated by
the headstock to the tin roller C, placed in the carriage A, the same is com-
municated to the tin roller C in the carriage B, by means of the bevil wheels e
and h, and the shaft H. And in like manner motion is conveyed from the
shaft d in the carriage A to the shaft d, in the carriage B by means of the
mitre wheels n and o, and shaft K. We have shewn bevil wheels of unequal
diameters in connection with the shaft H to convey motion from one tin roller
to the other, the wheels of largest diameter being fixed on that shaft, which
we have in practice found best, as we are enabled thereby to reduce the speed
of the shaft H below that of the tin rollers, whereas we have shewn mitre
wheels (which are of equal diameter) in connection with the shaft K, to convey
motion from one of the shafts which drives the tin drums to the other, as the
speed of such shafts is not so great as that of the tin rollers, and the speed
of the shaft K does not require to be reduced below that of the drums.
We

page_text: do not however confine ourselves to such bevil wheels in the one case or mitre
wheels in the other, as the same may be varied to suit the work and the speed
required. We have also shewn the shaft H as supported by the fixings I,
and stated that the shaft K is supported by bearings in the pipe E. We do
not however confine ourselves to such modes of supporting the shafts, as the
same may be supported in any other convenient manner.
Having now described the nature of our said Invention, and the manner in
which the same is to be performed, we declare that what we claim as of our
Invention, is the application as herein-before described, of a shaft and geering
to communicate motion from the tin roller in one carriage to the tin roller
in another where tin rollers are employed, and the like means where tin drums
are employed to communicate motion from the shaft which drives the drums
in the one carriage to the corresponding shaft in the other.
In witness whereof, we have hereunto set our hands and seals, the
Fourth day of August, in the year of our Lord One thousand eight
hundred and fifty-nine.
