CERTAIN IMPROVEMENTS IN COMBING MACHINES
Year: 1875

page_text: LETTERS PATENT to Thomas Henry Rushton and Benjamin Alfred
Dobson, both of the Firm of Messieurs Dobson and: Barlow, of
Bolton, in the County of Lancaster, Machine Makers, and James
Macqueen, of the same Place, Machinist, for the Invention of
**CERTAIN IMPROVEMENTS IN COMBING MACHINES.'
"
PROVISIONAL. SPECIFICATION left by the said Thomas Henry
Bushton, Benjamin Alfred Dobson, and James Macqueen: at, the
Office of the Commissioners of Patents, with their Petition, on.
the 23rd June 1875.
We, THOMAS HENRY RUSHTON and BENJAMIN ALFRED DOBSON, both
of the Firm of Messrs. Dobson and Barlow, of Bolton, in the County of
Lancaster, Machine Makers, and JAMES MACQUEEN, of the same Place,
Machinist, do hereby declare the nature of the said. Invention for
CERTAIN IMPROVEMENTS IN COMBING MACHINES," to be as follows:-

page_text: The body of the cylinder consists of a tube which is fixed by two
set screws on the shaft, to this tube are fixed by set screws two
segments, one fluted and the other containing the combs; the space
between the segments is filled up by plain segments; by this mode of
construction when the combs are worn or injured the comb segment can 5
be replaced by another without making the cylinder eccentric. The set
screws for securing the cylinder to the shaft are covered by the plain
segments and consequently do not collect flyings as now customary.
Another part of our Invention relates to the mode of adjusting the
detaching roller; to the bottom lifter shaft is keyed a lever in which is a 1
stud, the position of which is regulated by a set screw; this stud fits into
the end of a lever on the top lifter shaft; the other end of this lever acts
on a tube on the end of the detaching roller; by this arrangement two
adjacent detaching rollers can be adjusted by the regulating screw in
the bottom lever, no connecting rod is required, and one joint is 1
dispensed with.
Another part of our Invention relates to the mode of constructing the
top comb; hitherto these combs have been forged with the end brackets
in one piece; we now propose to make the comb plate detached from
the end brackets, but secured thereto by set screws or otherwise, thereby
saving space and economising labour.
The last part of our Invention consists in an improved mode of con-
necting the nipper arm and the connecting rod; we make a forked
end to the nipper arm, and the end of the connecting rod fits into this
fork; the stud forming the joint is held in the end of the connecting 2
rod by a set screw; by this mode of connecting the parts a better bearing
surface is obtained and the joint pin is held more firmly.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Henry Rushton, Benjamin Alfred Dobson,
and James Macqueen in the Great Seal Patent Office on the 22nd 8
December 1875.

page_text: Messieurs Dobson and Barlow, of Bolton, in the County of Lancaster,
Machine Makers, and JAMES MACQUEEN, of the same Place, Machinist,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of June, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Henry Rushton, Benjamin
Alfred Dobson, and James Macqueen, Her special licence that we, the
said Thomas Henry Rushton, Benjamin Alfred Dobson, and James
Macqueen, our executors, administrators, and assigns, or such others
as we, the said Thomas Henry Rushton, Benjamin Alfred Dobson, and
James Macqueen, our 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 In-
vention for "CERTAIN IMPROVEMENTS IN COMBING MACHINES," upon the con-
dition (amongst others) that we, the said Thomas Henry Rushton,
Benjamin Alfred Dobson, and James Macqueen, our executors or ad-
ministrators, by an instrument in writing under our, or their, or one
of our or their hands 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 within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Henry Rushton, Benjamin
Alfred Dobson, and James Macqueen, do hereby declare the nature of
our said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following
statement (that is to cool.

And in order that our Invention may be fully understood and readily.
carried into operation, we will proceed to describe the accompanying
Sheet of Drawings, reference being had to the figures and letters marked
thereon.
Fig. 1 is a transverse section; and Fig. 2, a longitudinal section of t
the combing cylinder constructed according to our Invention.
a is the
shaft of the comb; and b, the tube which is fixed to the shaft a by the
two set screws c, c; d is the ordinary fluted segment, the ends of which
are screwed to the tube b; and e is the comb segment which is also
screwed to the tube b. The spaces between the segments d and e are 1
covered by the plain segments ƒ and g secured to the tube b. The heads
of the set screws c are covered by the segment f, and are consequently
not liable to collect flyings as is the case in comb cylinders of the
ordinary construction in which the set screws are exposed. By thus
*constructing comb cylinders when the combs are worn or injured the 1
comb segment can be replaced by another without rendering the
cylinder eccentric, whereas in the ordinary mode of construction it is
practically impossible to change an injured comb segment.

Figs. 3 and 4 are two views of our improved roller lifter for adjusting
the detaching rollers. is the ordinary bottom lifter shaft to which is 2
keyed the lever ; in the upper end of this lever is a slot for the stud j,
the lateral position of which can be adjusted by the regulating screw k.
On the stud j is placed the square block ♬ fitting in the slot in the
lever / fixed to the ordinary top lifter shaft m. The upper arm of the
lever / acts on a tube on the end of the detaching roller, by this arrange- 2
ment two adjacent detaching rollers can be adjusted by the regulating
screw / in the lever i, no connecting rod is required as now customary,
and one joint is dispensed with.
⚫ Figs. 5 and 6 represent two views of a top comb constructed according
to our Invention. Hitherto these combs have been forged with the 8
end brackets in one piece, which is expensive and renders repairs
difficult. We now propose to make the steel comb bladen detached
from the end brackets o, but secured thereto by set screws or otherwise,
thereby saving space and economising labour.
Figs. 7 and 8 represent two views of our improved mode of connecting 8
the nipper arm and the connecting rod. p is the usual nipper shaft,
and to it is keyed the nipper arm q which is cast with a forked end to

page_text: receive the end of the connecting rod r, which is secured to the joint
pin & by the set screw t. By this mode of connecting the parts a better
bearing surface is obtained, and the joint pin is held more firmly than
heretofore.
Having thus stated the nature of our Invention, and described the
manner of performing the same, we declare that we claim,—
First. The improved mode of constructing the comb cylinders of
combing machines, as shewn and described.
Secondly. The improved mode of adjusting the detaching rollers of
combing machines, as shewn and described.
Thirdly. The improved mode of constructing the top combs of combing
machines, as shewn and described.
And, lastly. The improved mode of connecting the nipper arm and
the connecting rod of combing machines, as shewn and described.
In witness whereof, I, the said Thomas Henry Rushton, for myself
and on behalf of the said Benjamin Alfred Dobson and James
Macqueen, have hereto set my hand and seal, this Twenty-first
day of December, One thousand eight hundred and seventy-
five.
