Analogous Combing Machines.
We, EDWIN GAUNT, of Grangefield Mill, Stanningley, in the County of York,
Spinner, and WILLIAM HENRY COCKCROFT, of Victoria Terrace, and SAMUEL BEST, of
Gladstone Terrace, both of Stanningley aforesaid, Combing Overlookers, do hereby
declare the nature of this invention to be as follows:-
Hitherto one dabbing brush has been employed in connection with each dabbing
motion of Nobles and analogous combing machines and such brushes have been
mounted on one reciprocating slide or if two brushes have been used the slides on
which they are mounted have been operated by separate shafts there is therefore
excessive vibration when such brushes are run at a high speed which prevents the
efficient action of the comb.
Our improvements consist in using two brushes mounted on separate reciprocating
slides operated by the same shaft so arranged that one of said slides balances the other
and they are regularly reciprocated at the same speed so as to "dab" consecutively,
thus greatly checking the vibration and enabling the speed of the comb to be increased
besides imparting a more effectual "dab," and our improvements further consist in the
construction and arrangement of said slides together with the guides in which they
are mounted and the means for reciprocating the same, and also in the method of
lubricating the working parts.
To carry out our invention we preferably mount a box bracket on the pillar of the
comb which is provided with bearings for a double crank shaft or a shaft having two
eccentrics working within the said bracket, the said cranks or eccentrics being
diametrically opposite to each other. The two slides are fitted in suitable guides
formed outside the two sides of the said bracket parallel to the said shaft. Such
slides are provided with forked arms projecting through slots in the sides of the
bracket and are adopted to clasp or engage with the said cranks or eccentrics for the
purpose of reciprocating the slides to which they are attached. Feet are formed at
the bottom of the said slides to which the brushes are secured, and such brushes are

page_text: preferably arranged to work as closely together as possible. And the said arms
engaging with the cranks or eccentrics are adjustably connected to the slides they
actuate, therefore by adjusting such connections the depth the brushes enter the comb
may be regulated. The said shaft is actuated by a driving pulley, preferably mounted
on its outer end, connected by a strap to the top shaft of the comb.
For the purpose of lubricating the various parts, a lubricating chamber or cistern
is formed or mounted at the top of the said bracket in connection with and adapted
to lubricate all the working parts of the mechanism beneath. Or a receptacle may be
formed at the bottom of the said box bracket capable of containing a suitable
lubricant and arranging the cranks or eccentrics to dip into such lubricant at
each revolution.
If desired only one brush may be employed, in which case the second slide or a
modification thereof is used as a counterbalance.
Three brushes may also be used by employing a third slide operated by another
crank or eccentric on the said shaft in which case the said cranks or eccentrics are
preferably arranged at an angle of 120 degrees with each other so that the slides they
reciprocate balanco each other.

page_text: Improvements in Dabbing Brush Mechanism for Nobles and
Analogous Combing Machines.
We, EDWIN GAUNT, of Grangefield Mill, Stanningley, in the County of York,
Spinner, and WILLIAM HENRY COOKOROFT, of Victoria Terrace, and SAMUEL BEST,
of Gladstone Terrace, Stanningley aforesaid, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Hitherto one dabbing brush has been employed in connection with each dabbing
motion of Nobles and analogous combing machines and such brushes have been
mounted on one reciprocating slide or if two brushes have been used the slides on
which they are mounted have been operated by soparate shafts, there is therefore
excessive vibration when such brushes are run at a high speed which prevents the
efficient action of the comb.
Our improvements consist in using two brushes mounted on separate reciprocating
slides operated by the same shaft so arranged that one of said slides balances the
other and they are regularly reciprocated at the same speed so as to "dab"
consecutively, thus greatly checking the vibration and enabling the speed of tho
comb to be increased besides imparting a more effectual "dab."
To carry out our improvements we preferably mount a box bracket upon the pillar of
the comb which is provided with bearings for a double crank shaft or a shaft provided
with two eccentrics, the throw of the said cranks or eccentrics being diametrically opposite
to each other. The brush slides are mounted between guides formed in the said bracket
and are provided with suitable arms or projections adapted to clasp or engage the
said cranks or eccentrics for the purpose of reciprocating the slides. Feet are
formed at the bottom of such slides to which the brushes are secured and such
brushes are preferably arranged to work as closely together as possible.
The said arms engaging with the cranks or eccentrics are adjustably connected to
the slides they actuate therefore by adjusting such connections the depth such brushes
enter the pins of the combs or circles may be regulated.
The said eccentric shaft is preferably actuated by a driving pulley mounted upon
its outer end and connected by a strap to the top shaft of the comb.
If desired only one brush may be employed in which case the second slide or a
modification thereof is used as a counterbalance. Or three brushes may be used by
employing a third slide operated by another eccentric on the eccentric shaft the
throw of the said eccentrics being relatively arranged at an angle of 120 degrees with
each other.
It is obvious that a similar arrangement of mechanism may be employed to actuate
the brushes at the other side of the comb.
For the purpose of more clearly describing our invention reference is to be had to
the accompanying sheet of drawings in which similar letters of reference indicate
corresponding parts in each of the figures.
Figure 1, is an elevation of a dabbing motion constructed in accordance with our
invention and mounted in the usual manner above the combing circles a portion of
the small circle being shown together with a section of the large circle.

page_text: Figure 2, represents a vertical section of the dabbing motion on the central line of
the eccentric shaft.
Figure 3, is a horizontal section on the centre line of the eccentric shaft.
Figure 4, is a vertical section at right angles to figure .2 and cutting the eccentric
shaft between the two eccentrics.
Figure 5, is a plan of one of the said slides.
Figure 6, is a front view of the same.
Figure 7, is a front view of the adjustable piece provided with the projections
engaging the eccentric, and Figure 8, is a side view of the same.
The bracket A is secured by the arms B to the pillar C of the comb and each
bracket is provided with bearings D for the shaft E having two eccentrics F with
their throw diametrically opposite.
The bracket A is formed hollow with the outer side G detachable for convenience
in forming the vertical guides H, H, provided with adjustable V pieces J. The said
guides are fitted with slides K, K, having projections L, L, clasping or engaging the
eccentrics F, F, in such a manner that such slides are reciprocated by the rotation of
the eccentrics. Feet N, N, are formed at the bottom of the slides K, K, adapted to
hold the brushes O, O, which are arranged to "dab" the fibres into the large circle P
and small circle Q in the usual manner.
In order to regulate the depth the brushes enter the pins S of the circles the
projections L, L are capable of vertical adjustment in relation to the slides to which
they are attached.
Such projections on each of the slides are preferably formed on an adjustable piece T
which fits between the V edges U provided on the slides and such piece is fixed to
the slide after adjustment by the bolts V passing through such slide and the slot W
formed beneath the lower projection L. An adjustable wedge piece Y is fitted to the
lower projection of each slide to enable the distance between the upper and lower
projection to be regulated so as to compensate for the wear of the parts.
The brushes we preferably use are approximately half the size of an ordinary brush
and together resemble an ordinary brush in form.
An oil cistern a is preferably fitted in a recess d over the above described mechanism
and suitable wicks draw the oil through the tubes e and allow it to drop into the
hollows h, h, formed in the upper projections L, L, and it passes through the holes m
on to the eccentrics F, F.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare what we
claim is:
1. A dabbing motion for combing machines having two brushes mounted on separate
reciprocating slides operated by cranks or eccentrics on the same revolving shaft with
their throw in opposite directions, substantially as and for the purpose shown and
illustrated in the accompanying drawings.
2. A dabbing motion for combing machines having three brushes mounted on
separate reciprocating slides operated by eccentrics or their equivalent on the same
revolving shaft with their throw at an angle of 120 degrees with each other,
substantially as and for the purpose shown and illustrated in the accompanying
drawings.
