ROBERT SPEIGHT and THOMAS SPEIGHT, junior, Commission Wool Combers, of
Bradford, in the County of York. " IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."
"
Our Invention consists in a new application to the well-known "Noble's" combing
machine, or other similar combing machine, by which the " dabbing brush is
actuated by an excentric and belt instead of the present connecting rod and gear,
whereby a stendy and regular action is given to the dabbing brush, producing
better work, and effecting a great saving in the wear and tear of the brushes.
For this purpose we fit on the pillar of the small inner circular comb, brackets
having guides in which works up and down a slide, having at the bottom end a
flange to which is fixed the "dabbing brush." On the front of the bracket is fixed
a face plate having near the centre a slot hole in which works freely a stud which
is fitted to the slide of the "dabbing brush;" this stud is also fitted in the top of
a link, which is made with a circular opening in which works a ring (by preference
made of brass). In the ring is fitted an excentric formed on the side of a driving
pulley a flange is formed on the excentric, and a loose flange is screwed on after
the excentric is passed through the ring, preventing the ring moving out of position.
The excentric works with great velocity, and produces great wear and tear. When
the excentric works slack, the ring is removed, and a new one placed on the
excentric.
We may construct our apparatus with the excentric working in the circular

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Robert Speight and Thomas Speight in the Great Seal Patent Office
on the 13th December 1877.
ROBERT SPEIGHT and THOMAS SPEIGHT, junior, Commission Wool Combers, of
Bradford, in the County of York. "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES.'
The said Invention consists in a new application to the well-known "Noble's"
combing machine, or other similar combing machine, by which the "dabbing brush"
is actuated by an excentric and belt, or by a connecting rod, crank, and belt instead
of the present connecting. rod and gear, whereby a steady and regular action is
given to the "dabbing brush," producing better work, and effecting a great saving in
the wear and tear of the brushes.
For this purpose we fit on the pillar of the small inner circular comb brackets
having guides in which a slide works up and down, having at the bottom end a
flange to which is fixed the "dabbing brush." On the front of the brackets is
fixed a face plate having near the centre a slot hole in which works freely a 'stud,
which is fitted to the slide of the "dabbing brush;" this stud is also fitted in the
top of a link, which is made with a circular opening in which works an excentric,
which is formed on the side of a driving pulley.
In the bottom end of the face plate is secured a bolt or stud having a collar; on
the bolt is fitted the excentric and driving pulley; a recess is formed in the link, in
which oil is placed to lubricate the excentric and bolt. On the top shaft of the
pillar is fitted a pulley, over which and the excentric pulley is fitted a belt. The
shaft is actuated in the usual way, giving motion to the pulley fitted thereon, which
actuates by the belt the excentric driving pulley, turning the excentric, giving a
lifting and lowering quick motion to the link, which actuates the slide and "dab-
bing brush."
On the top shaft is fitted a small fly wheel; or we fit on the top shaft, close to
the pillar head, a driving pulley which actuates another pulley fitted on a small
shaft, which is fitted in a suitable bearing formed on the flange plate of the brackets
fixed to the pillar; on this shaft is fitted a fly wheel. In front of the pulley is
formed.or cast an excentric on which works an excentric ring made with arms joined
to a boss which is fitted on a stud fixed to the slide, on which is fitted the "dabbing
brush." In this case the driving belt is behind the slide, and the top driving pulley

page_text: is close to the head of the pillar, doing away with an overhanging shaft. Or we
actuate the slide and "dabbing brush" by means of a connecting rod, which is fitted
on a stud fixed on a disk crank, and which is formed on the bottom driving pulley;
the other end of the connecting rod is fitted in a boss formed on a stud, which is
fixed to the slide of the "dabbing brush."
By these means we prevent the thumping of the brush, produce an easy and
effective pressure on the fibres, and prevent great wear and tear of the brushes or
bristles, and run the comb with greater speed and steadiness.
But in order to enable our improvements to be better understood we will proceed
to more particularly describe the same by reference to the accompanying Drawing,
in which,
Figure 1 represents a side elevation (shewing the link, excentric, and bottom
driving pulley in section) of the improved apparatus for actuating the " dabbing
brush" by an excentric and belt, the belt working outside the "dabbing brush
slide; Figure 2, front view of the same.
Figure 3. represents a side elevation of an apparatus for a similar purpose with
the driving belt working behind the “dabbing brush" slido; Figure 4, front view
of the same.
Figure 5 represents a side elevation of an apparatus for a similar purpose, the
"dabbing brush" slide being actuated by a disc crank and connecting rod; Figure 6,
front elevation of the same.
Similar letters of reference are used in all the Figures to represent similar
parts.
On the pillar A (Figures 1 and 2) of the small inner circular comb we fit brackets
B cast with a flange C, which is accured to the pillar by screwed bolts and nuts.
These brackets are formed with guides, in which works up and down a slide D,
having at the bottom end a flange E, to which is fixed the "dabbing brush" F.
On the front of the brackets is fixed a face plate G, having a slot hole H, in which
works freely a stud I, which is fitted to the slide D. On a turned down part J of
the stud I is fitted the top K of a link L, which is made with a circular opening in
which works an excentric M formed on the side of a driving pulley N; in this
pulley is fitted a balance weight O. The link L is made with a recess P, in which
is placed oil, and which passes through the opening Q to lubricate the excentric
and bolt R, which is formed with a collar S, and fitted in the bottom end of the
face plate G. On the top driving shaft T is fitted a pulley U and small fly wheel
V; the shaft T is actuated in the usual manner, giving motion to the pulley U, and
actuating by a belt W the pulley N and excentric M, giving a lifting and lowering
quick motion to the link L, which actuates the slide D and "dabbing brush" F.
Figures 3 and 4.-We fit on the top driving shaft T a pulley U close to the
pillar head x, which actuates by means of a belt W another pulley N; this pulley
is made with an excentric M, in front on which works an excentric ring Y formed
with arma Z, which are joined to a boss A¹, in which is fitted a stud B¹ fixed to
the slide D to which is fitted the "dabbing brush" F. The pulley N is fitted on a
small shaft C, which is fixed in a projecting bracket D₁ cast on the flange C of the
brackets B. In the guides formed in the brackets works up and down the slide D,
to which is fitted the "dabbing brush." On the small shaft C¹ is fitted a small fly
wheel V. In this case the driving belt W works behind the slide D, and the
driving pulley U is fitted close to the pillar head, doing away with an overhanging
shaft.
Figures 5 and 6.-We also fit on the top driving shaft T a pulley U close to the
pillar head x, which actuates by means of a belt W a pulley N fitted on a stud E¹,
which is fitted in a boss F¹ formed on a bracket G¹, which is bolted to the pillar A;
the bracket G¹ is fixed under the slide frame B. The pulley N is fitted with a
stud H', on which works the connecting rod head I' of the connecting rod J¹; the
top end is fitted in a boss K¹ on the bolt L', which is fixed to the slide D. The
pin His fixed at a given distance from the centre of the pulley, according to the
required stroke to be given to the dabbing brush slide and "dabbing brush," the

page_text: pulley N forming a disc crank. In this case also the driving pulley U is fitted
close to the pillar head, and the driving belt works behind the dabbing brush
slide, but the slide is actuated by a crank and connecting rod instead of an
excentric.
Having thus described our improvements, and the best means we are acquainted
with for carrying the same into effect, we would have it understood that we do
not confine ourselves to the precise details shown and described, as they may be
varied without departing from the peculiar character of the Invention; but what
we do claim is,-
<
"
Firstly. The method or means of actuating the dabbing brushes of combing
machines by belts or straps and pullies, whereby a steady and regular action is
