Year: 1869

page_text: LETTERS PATENT to Thomas Greenwood and John Bapty, of Leeds,
in the County of York, Machinists, for the Invention of "IMPROVED
MACHINERY BAD CAMPING SOLE AND AMEND FIRDOUS MATERIALS"
Sealed the 25th February 1870, and dated the 1st September 1869.
PROVISIONAL SPECIFICATION left by the said Thomas Greenwood
and John Bapty at the Office of the Commissioners of Patents, with
their Petition, on the 1st September 1869.
We, THOMAS GREENWOOD and JOHN BAPTY, of Leeds, in the County
of York, Machinists, do hereby declare the nature of the said Invention
for "IMPROVED MACHINERY FOR COMBING SILK AND OTHER FIBROUS MATERIALS,"
to be as follows:-
The chief object of this Invention is to provide a simple and efficient
means for presenting the opposite ends of wool, silk, or other fibres
intended to be combed alternately to the working combs of the combing
machine. To this end the fibres supplied to the carrying comb are taken
up by a narrow endless band provided with teeth or pins, and carried
forward into the nip of a novel turning and transferring apparatus con-

page_text: sisting of two grooved tension pulleys, in the grooves of which is laid a
band of steel wire or its equivalent; this steel band travels at the same
surface speed as the narrow band with teeth, and runs side by side there-
with. The fibres to be combed are laid crosswise in the teeth of the
band, and as they come to the nip of the steel band and first pulley
the band will lift them out of the teeth and hold them fast against the
grooved periphery of the tension pulley. While thus held firmly one
end of the fibres is brought under the action of a working comb, which
straightens the fibres by a continuous operation. As the fibres are
combed they are raised by the rotation of the pulley to a level with a
second narrow band, provided like the first with teeth or pins, which
band runs side by side with the steel band in its course to the second
grooved tension pulley, but it is placed at a slight angle thereto. As
the fibres reach this second band of teeth they are released from the nip
of the first pulley and steel band and are delivered on to or taken up by
the travelling teeth, which in turn deliver the fibres into the nip of the
steel band with the second pulley, the combed portion by reason of the
angular diverson of the toothed band being brought into line with the
grooved pulley. The rotation of this pulley will carry round the fibres
and present them to the action of a second working comb. This comb
having acted upon the uncombed portion of the fibres the fibres now
completely combed will be carried round by the pulley to the ordinary
circular comb, from which they may be drawn off by rollers in the usual
manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Greenwood and John Bapty in the Great
Seal Patent Office on the 1st March 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
GREENWOOD and JOHN BAPTY, of Leeds, in the County of York,
Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of September, 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 us, the said Thomas Greenwood and John Bapty,

page_text: Her special licence, that we, the said Thomas Greenwood and John
Bapty, our executors, administrators, and assigns, or such others as we,
the said Thomas Greenwood and John Bapty, our 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 ex-
pressed, 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 "IMPROVED MACHINERY FOR
COMBING SILK AND OTHER FIBROUS MATERIALS," upon the condition (amongst
others) that we, the said Thomas Greenwood and John Bapty, our
executors or administrators, by an instrument in writing under our, 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 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 Thomas Greenwood, on behalf of
myself and of the said John Bapty, do hereby declaro 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, reference being had to the Drawings hereunto annexed, and
to the letters and figures marked thereon (that is to say):-
The chief object of this Invention is to provide a simple and efficient
means for presenting the opposite ends of wool, silk, or other fibres
intended to be combed alternately to the working combs of the combing
machine. To this end the fibres to be combed are laid by the carrying
comb on to a narrow endless belt or band provided with teeth or pins,
and carried forward into the nip of a novel turning and transferring
apparatus. This apparatus consists of two grooved tension pulleys
mounted vertically, and provided with an endless cord of steel wire or
its equivalent. This wire travels at the same surface speed as the narrow
band with teeth, on to which the carrying comb lays the fibres, and its
lower portion runs side by side therewith. The fibres to be combed are
laid crosswise in the teeth of the band, and as they come to the nip of
the steel wire and first pulley the wire will lift them out of the teeth, and
hold them fast against the grooved periphery of the tension pulley; while
thus held firmly one end of the fibres is brought brought under the action
of a working comb, which straightcus the fibres by a continuous opera

page_text: tion. As the fibres are combed they are raised by the rotation of the
pulley to a level with a second narrow belt or band provided like the
first with teeth or pins, which band runs side by side with the steel
wire in its course to the second grooved tension pulley, but it is placed
at a slight angle thereto. As the fibres reach the level of this second band
of teeth they are released from the nip of the first pulley and wire
cord, and are delivered on to or taken up by the travelling teeth, which
in turn deliver the fibres into the nip of the wire with its second tension
pulley, the combed portion by reason of the angular diversion of the
toothed band being brought into line with the grooved pulley. The
rotation of this pulley will carry round the fibres and present them to
the action of a second working comb, which will act upon the un-
'combed portion of the fibres. On the completion of this operation the
fibres will be carried round by the pulley and wire to the ordinary
circular comb, from which they may be drawn off by rollers in the usual
manner.
In the accompanying Drawings we have shewn in several views an
arrangement of combing machinery with our improved transferring
apparatus adapted thereto, Fig. 1 being a plan view of the machine;
Fig. 2, a side elevation; and Fig. 3, an end elevation of the same.
A, A, A, is the framework of the machine; B, B, are standards
mounted upon this framing, and carrying the stud axles of the gripping
pulleys, as well as those of the pulleys which carry the bands armed with
pins or teeth. The standards are fitted with adjustable screws so as to
keep the gripping wire or cord at a proper tension. D and D' are the
gripping pulleys mounted upon suitable studs. These pulleys are grooved
on their periphery to receive a wire cord d made of any suitable material,
either solid or compound; we prefer the latter. The bottom of this
groove is further recessed out to receive a strip of leather, vulcanized
india-rubber, or other elastic material, so as to compensate for any
irregularity in laying on the material to be combed. E, E, Figures 2
and 3, is a belt or band of ordinary card filleting passing round and held
at tension by the pulleys F, F, F.
Fig. 4 is an ordinary screw gill feeding head with the usual nipping
apparatus and carrying comb for supplying the fibres to be combed to
the combing machine. The carrying comb as it takes the tufts of
fibrous material from the jaws of the nipping apparatus deposits the
same upon and between the teeth of the card filleting E, whence it is

page_text: conveyed into the bite of the wire cord d and wheel D. When firmly
gripped it is carried round to the usual combing sheet or roller brush
and doffer, shewn at G, Figures 1 and 2. Here one end of the tufts are
combed or cleaned, and they are then carried forward to another card
fillet H, which passes over two pairs of pulleys I and J, which carry two
bands of card filleting, one on each side of the gripping cord and
pulleys D and D₁; these bands of filleting convey the partially combed
tufts to the bite of the pulley D' and cord d. The pulleys D and D' are
placed in line of each other, but the pullies I and J (see Fig. 1) are
placed slightly diagonally to the pulleys D and D', so as to grip the
partially combed fibre in the part already combed, the tufts being again
gripped by the pulley D', and the cord are next presented to the combing
or cleaning apparatus K, which completes the combing or cleaning
operation. L, Fig. 1, is the usual circular comb, which is placed on a
level with the lower edge of the pulley D', and as the tufts of cleaned
fibre are released from the grip of the pulley and cord D' they are forced
between the pins of the circular comb L, whence they are drawn off in
the usual manner, as is clearly shown in the Drawing.
Figures 5, 6, and 7 are enlarged views of our improved gripping
apparatus shewing the manner in which the tufts of fibrous material
are presented to the combing or cleaning cards. The ordinary feeding
head, shewn at Fig. 4, is driven in the usual manner by the pulleys M
mounted upon the driving shaft a. On the opposite end of this shaft is
the pulley b, which conveys motion by means of the strap c to the
pulley e on the end of the horizontal shaft e¹. A bevil pinion on this
shaft takes into a bevil wheel on the horizontal shaft f, and by a train
of spur wheels of suitable dimensions gives the required motion to the
gripping pulley D. 9, 9, 9, are a train of spur wheels communicating
motion from the shaft of the gripping pulley D to the gripping pulley D₁
so as to insure an uniform motion of the two pulleys D and D'. The
shaft e' communicates motion to the combing heads G and K in the
usual manner. is the carrying or "porter" comb worked by a crank
in the usual manner, and serving to deliver the tufts of fibres on to the
endless band of filletting E.
Having now set forth the nature of our Invention of " Improved
Machinery for Combing Silk and other Fibrous Materials," and ex-
plained the manner of carrying the same into effect, we wish it to bo

page_text: understood that under the above in part recited Letters Patent we
claim,―
First. The arrangement of combing machine constructed and operating
as above described.
Secondly. The application to combing machines of the turning and
transferring apparatus above described.
In witness whereof, I, the said Thomas Greenwood, have hereunto
set my hand and seal, the Twenty-eighth day of February, in
the year of our Lord One thousand eight hundred and seventy.
THOMAS GREENWOOD. (L.S.)
