MACHINERY OR APPARATUS FOR COMBING AND SLIVERING SILK OR OTHER
FIBROUS SUBSTANCES."
Sealed the 11th August 1871, and dated the 14th February 1871.
PROVISIONAL SPECIFICATION left by the said Abraham Jagger at
the Office of the Commissioners of Patents, with his Petition, on
the 14th February 1871.
I, ABRAHAM JAGGER, of Halifax, in the County of York, Machine
Broker, do hereby declare the nature of the said Invention for "In-
PROVEMENTS IN MACHINERY OR APPARATUS FOR COMBING AND SLIVERING SILK OR
OTHER FIBROUS SUBSTANCES," to be as follows:-
This Invention consists of a slide bed or table with a series of portable
comb plates fitting to and capable of sliding in or upon suitable guides
formed on the said bed or table, such plates being propelled by a screw
or other suitable means.

page_text: The said comb plates are constructed in suitable lengths equal to
the lengths of the "dressing boards" of the ordinary silk dressing frame,
and the pins or teeth are made of suitable pitch and number of rows
according to the particular kind of fibrous substance to be combed and
slivered. One or more pairs of drawing off rollers are mounted in
suitable bearings on the said bed or table, and so placed that as the
combs are caused to slide or travel on the bed they will pass near to the
said drawing off rollers. A tuft of silk or other substance, after being
dressed in the boards of the dressing frame in the usual manner is trans-
ferred by the attendant to one of the comb plates which is then placed
on one end of the bed or table to be propelled forward past the drawing
off rollers; another plate is then supplied with a tuft in like manner,
and placed on the bed plate with its end close to the end of the former,
and another plate supplied as before is placed thereon in succession, and
so on, thus forming a continuous procession of comb plates supplied or
charged with the tufts of silk or other substance after having been
dressed in the boards of the ordinary dressing frame, which silk or
fibrous substances is drawn off by the rollers and formed into a sliver in
a similar manner to the drawing off and slivering and forming slivers of
wool by ordinary wool combing machinery.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Abraham Jagger in the Great Seal Patent Office
on the 14th August 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ABRAHAM
JAGGER, of Halifax, in the County of York, Machine Broker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourteenth day of February, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Abraham Jagger, Her special
licence that I, the said Abraham Jagger, my executors, administrators,
and assigns, or such others as I, the said Abraham Jagger, 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

page_text: 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 "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR COMBING AND SLIVERING SILK OR OTHER FIBROUS
SUBSTANCES," upon the condition (amongst others) that I, the said Abraliam
Jagger, 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 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 Abraham Jagger, 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 Invention consists of a slide bed or table with a series of portable
comb plates fitting to and capable of sliding in or upon suitable guides
formed on the said bed or table, such plates being propelled by a screw
or other suitable means.
The said comb plates are constructed in suitable lengths equal to the
lengths of the "dressing boards" of the ordinary silk dressing frame,
and the pins or teeth are made of suitable pitch and number of rows,
according to the particular kind of fibrous substanc to be combed and
slivered. One or more pairs of drawing off rollers are mounted in
suitable bearings on the said bed or table, and so placed that as the
combs are caused to slide or travel on the bed they will pass near to
the said drawing off rollers. A tuft of silk or other substance after
being dressed in the boards of the dressing frame in the usual manner
is transferred by the attendant to one of the comb plates which is then
placed on one end of the bed or table to be propelled forward past the
drawing off rollers; another plate is then supplied with a tuft in like
manner, and placed on the bed plate with its end close to the end of
the former, and another plate supplied as before is placed thereon in
succession, and so on, thus forming a continuous procession of comb
plates supplied or charged with the tufts of silk or other substances
after having been dressed in the boards of the ordinary dressing frame,
which silk or fibrous substances is drawn off by the rollers and formed

page_text: into a sliver in a similar manner to the drawing off and slivering and
forming slivers of wool by ordinary wool combing machinery.
This Invention will be readily understood by reference to the accom-
panying Sheet of Drawings, wherein Fig. 1 is the side elevation, Fig. 2
the plan, and Fig. 3 a cross section of a machine or apparatus con-
structed in accordance with the said Invention.
A is the slide bed or table supported on framework B. This bed
is similar in construction to the slide bed of a turning lathe and planed
true in like manner, and also provided with a screw shaft C carried in
the frame and to which rotary motion is given; D is one of a series of
comb plates which are constructed in suitable lengths and to fit the
bed so as to slide freely thereon, and having rack teeth formed on
their under surface to fit and gear with the screw shaft C so that by
the rotation of said shaft the plates are caused to slide on the bed; the
said plates being provided with hooked flanges E underneath to fit and
clip under guide ribs F formet on the bed to prevent the said plates
being lifted up by the action of the screw. These plates are provided
on the upper surface with comb teeth or pins of suitable pitch and
arranged in any desirable number of rows according to requirement to
receive tufts of silk or other fibrous substance after being dressed on
the ordinary boards of a dressing machine; G are a pair of ordinary
horizontal drawing off rollers supported in stands H fixed upon the table,
and I are a pair of ordinary vertical drawing off rollers also in stands
J, fixed to the table. These rollers are provided with endless belts in
the usual manner. It will now be easily seen that if a tuft of silk or
other fibrous substance dressed in the ordinary dressing boards of a
dressing machine in the usual manner be transferred to one of these
comb plates, the dressed end or fringe projecting from the side of it and
the plate placed upon the bed at the end marked K with one or more of
the rack teeth taking into the screw when in motion in the right
direction, the said plate will be thereby propelled along the bed in the
direction of the arrow towards the other end, passing the rollers G which
will seize the projecting fringe and draw off a sliver therefrom, thence
passing the rollers I they will draw off another sliver of short fibre.
Another plate being supplied with a tuft from another dressing board
and placed on the bed immediately after and closely adjoining the end of
the former plate, having one or more of its rack teeth in gear with the
screw it will thereby be also propelled forward past the drawing off

page_text: rollers and so on in succession with other plates. And as each comb
plate arrives at the other end of the bed it is taken off and the noil
removed ready for further use or to be again supplied with a tuft
from the dressing boards in like manner as before.
Having thus described the nature of the said Invention and shewn
by Drawings in what manner the same is to be or may be performed
or put into practical operation, I would have it clearly understood that
I do not confine myself to the precise construction of the machine or
apparatus shewn, but what I claim as my Invention is the construction
and use of machinery or apparatus for combing and slivering silk or
other fibrous substances in manner substantially as shewn and described
herein.
In witness whereof I, the said Abraham Jagger, have hereunto set
mu hand and cool this Twelfth day of August in the year of our
Signed, sealed, and delivered by
the within-named Abraham
Jagger, in the
presence of
J. W. TASKER,
Clerk to W. Tasker,
