Year: 1882

page_text: LETTERS PATENT to Daniel Smith, Henry Smith and William Smith all of
Keighley in the County of York Machine Wool Combers for an Invention of
IMPROVEMENTS IN SCREW GILL-BOXES FOR PREPARING WOOL AND OTHER
FIBROUS SUBSTANCES.
PROVISIONAL SPECIFICATION left by the said Daniel Smith, Henry Smith,
and William Smith at the Office of the Commissioners of Patents on the
16th August 1882.
DANIEL SMITH, HENRY SMITH and WILLIAM SMITH, all of Keighley in the County
of York, Machine Wool Combers IMPROVEMENTS IN SCREW-GILL BOXES FOR
PREPARING WOOL AND OTHER FIBROUS SUBSTANCES
Our invention relates to certain improvements in screw-gill boxes, and has for
its object the more effectual preparation or opening out of long or short stapled
fibrous substances.
Our object is accomplished by placing one or more combs between the ordinary
fallers and back rollers. A vertical reciprocating motion is imparted to the comb
or combs the pins or teeth of the latter passing through the fibre at about right
angles to the direction in which the fibre travelling, thereby assisting the fallers
to open out or straighten the fibre and by the application of a dabbing brush
working in conjunction with the before mentioned comb or combs, the fibre is
pressed further down the teeth of the fallers than is the case when operated upon
by ordinary machines, thereby by our combination the liability of the fibre to
ride on the points of the pins or teeth of the fallers is reduced.

by the said Daniel Smith, Henry Smith, and William Smith in the Great
Seal Patent Office on the 15th February 1883.
DANIEL SMITH, HENRY SMITH and William Smith all of Keighley in the County
of York, Machine Wool Combers IMPROVEMENTS IN SCREW-GILL BOXES FOR
PREPARING WOOL AND OTHER FIBROUS SUBSTANCES
Our invention relates to certain improvements in Screw-gill boxes having for its
object the more effectual preparation or opening out of long or short stapled fibrous
substances and consists of placing between the ordinary back rollers and fallers one
or more combs having a vertical reciprocating motion, the pins or teeth of such
comb or combs passing through the fibre at about right angles to the direction in
which the fibre is travelling, thereby assisting the fallers to open or straighten out
the fibre, and by the application of a dabbing brush working in conjunction with
the additional comb or combs, the fibre is pressed further down between the teeth
or pins of the fallers, the liability of the fibre riding on the points of the teeth or
pins being thereby reduced.
Such being the object and nature of our invention, we will now proceed more
fully to describe the same, reference being made to the accompanying drawings, in
which like parts are indicated by similar letters.
Figure 1 represents a side elevation of such portions of a screw-gill preparing
box as are required to ellucidate our invention, one of the side frames of the
machine being removed in order to better illustrate our improvement. Figure 2 is
a sectional plan of portions of a screw-gill preparing box with our improvements
added Figure 3 is an enlarged front elevation of our improved intermediate comb,
and Figure 4 is a transverse section through line a. b. shewing the angle at which
we prefer to fix the comb pins or teeth.
In the drawings we have only shewn one set of intermediate combs but we
wish it to be understood that for long stapled fibre more may be added, and may
be actuated from the same levers as are employed when only one set of combs are
in use.
The side frames of the machine are indicated by the letter A and motion to the
machine and the parts that are old is communicated in the ordinary manner. To
the shaft B is secured an eccentric C which is connected to the lever D by eccentric
rod E. The shaft to which lever D is secured is mounted in journals formed in
brackets F secured to each side frame of machine: on this shaft are also secured
two levers G, and to these levers are jointed the upright rods H. H. to which the
combs are secured. The tops of these rods are held together and kept parallel by
cross bar J which is reduced and made circular at the ends, the reduced parts
passing through the ends of levers K. K. mounted to suitable brackets L. L.
The fibre is fed to the machine in the usual manner and travels in the direction
of the arrow passing between the back rollers P to the fallers R only a few of which
are shewn in the drawing. It will be easily understood that by the eccentric C
revolving, the levers secured to shaft D' will impart a reciprocating motion to the
rods H. H. and combs M and M' secured to the same. The teeth of these combs
alternately passing through the travelling fibre, and being stationary in the direction
to which the fibre is travelling, opens out and straightens the fibre passing through
the same, the vertical reciprocating motion preventing too much strain being put
upon the fibre, and the knotted portions damaging the comb teeth as would be the
case was the intermediate comb stationary.
By the downward motion of the intermediate combs, the cross bar or back of the
top comb M presses the fibre down, between the teeth of the fallers R, and in order

page_text: to prevent the fibre rising, during the upward motion of the comb, we introduce a
dabbing brush N secured to levers S. S. The opposite ends of these levers are
mounted on studs projecting from the arms L' of brackets L, L, and are actuated
by pins at T secured to the levers K. K. passing through the levers S. S; thus by
this arrangement of levers and attachments, when the rods H. H. and intermediate
combs are ascending, the dabbing brush N is descending thereby pressing the fibre
down between the faller teeth and preventing the bottom portion of the comb at M¹
raising the fibre towards the points of the faller pins.
Having thus described our invention and the manner in which the same may
be carried into effect we would have it understood, that we do not confine ourselves
to the precise angle at which the teeth or pins of the intermediate comb are shewn,
nor to the precise details for working the same, as both the angle of the teeth, and
the arrangement for working the comb, may be varied without departing from the
characteristic feature of our invention, but what we believe to be new and desire to
protect by Letters Patent is :-
The application of reciprocating combs mounted between the back rollers and
fallers in screw-gill preparing boxes substantially in the manner and for the
purpose as hereinbefore described, and as illustrated by the accompanying
drawing.
In Witness whereof, I the said Daniel Smith for and on behalf of myself and
the said Henry Smith and William Smith, have hereunto set my hand and
seal this 13th day of February in the year of our Lord One thousand
aight hundred and eighty three
DANIEL SMITH (LS.)
