PROVISIONAL SPECIFICATION.
We, WILLIAM TERRELL GARNETT, of the firm of William Garnett & Co., of
Barkerend Road, Bradford, in the County of York, Spinners, and JOHN WHEATER,
Engineer, of Bradford aforesaid in the employ of the said firm of William Garnett
& Co, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DABBING APPARATUS' EMPLOYED IN COMBING WOOL AND OTHER FIBROUS
SUBSTANCES" to be as follows:-
Our Invention relates to improvements in dabbing apparatus employed in
combing wool and other fibrous substances the said improvements consisting in
the employment of a light mechanical arrangement for actuating the "dabbing
brushes" of combing machines whereby the present heavy cast iron slide, guides
and carrier are dispensed with in " dabbing brush" apparatus of that class for
which Robert and Thomas Speight obtained Letters Patent dated the 14th day of
June 1877 and numbered 2328 in which the said cast iron slide, guides and carrier
work up and down the "dabbing brush" and are actuated by an excentric and link
worked by a pulley driven by a belt.
In carrying out our Invention we employ one or two steel or iron tubular rods
(by preference steel tubing or hollow steel rods); the top or tops of the said steel
rod or rods is or are fitted on a boss or bosses on a light metal casting the centre of
which is made with a slotted piece through which is passed a stud connected to the
head of the excentric link boss; the nut is screwed on the end of the stud to
secure the same in the link boss and to the light casting carrying the steel tube or
tubes or rod or rods.
The bottom part of the steel tube or tubes is formed with a boss or bosses
through which is or are passed a bolt or bolts to secure the shoe carrying the
dabbing brush "; the steel rods work through the heads of the brackets fitted to
the dabbing brush apparatus and over the brackets is fitted a plate or cover which
is secured by bolts or nuts.

The slot hole of the light top casting allows of regulating the stroke of the
dabbing brush" according to requirements.
We also employ a shoe or dabbing brush carrier of peculiar construction by which
we are enabled to lower the dabbing brush when required and according to the
wear and tear of the dabbing brush,

page_text: For this purpose we make the shoe or dabbing brush carrier with a projecting
boss and we form it at the extremity with a slot hole; the dabbing brush carrier
or shoe can be lowered when the bristles of the dabbing brush are worn by lifting
up the bolt passed through the bottom boss of the steel rod and through the slot
hole of the shoe or carrier.
By the employment of light steel or iron tubes as hereinbefore described we
produce very light up and down motions for "dabbing brushes" which can run at
a much higher speed and give a steadier motion with less wear and tear.

Barkerend Road, Bradford, in the County of York, Spinners, and JOHN WHEATER,
Engineer, Bradford, in the employ of the said firm of William Garnett & C°
aforesaid do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
DABBING APPARATUS EMPLOYED IN COMBING WOOL AND OTHER FIBROUS
SUBSTANCES" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
Our Invention relates to improvements in dabbing apparatus employed in
combing wool and other fibrous substances the said improvements consisting in
the employment of a light mechanical arrangement for actuating the dabbing
brushes of combing machines whereby the present heavy cast iron slide guides and
carrier are dispensed with in dabbing brush apparatus of that class for which
Robert and Thomas Speight obtained Letters Patent dated the Fourteenth day of
June 1877 and numbered 2328 in which the said cast iron slide guides and carrier
communicate an up and down motion to the dabbing brush and are actuated by an
eccentric and link worked by a pulley driven by a belt.
In carrying out our Invention we employ one or more wrought iron or steel
tubular rods (by preference steel tubing or hollow steel rods); the top or tops of
the said iron or steel rod or rods is or are fitted on a boss or bosses on a light metal
frame or casting in the centre of which is a slot through which passes a stud
connected to the head of the eccentric link boss; the nut is screwed on the end of
the stud to secure the same in the link boss and to the light metal frame or casting
carrying the steel tube or tubes or rod or rods.
The bottom part of the iron or steel tube or tubes is formed with a boss or
bosses through which is or are passed a bolt or bolts, to secure the shoe carrying
the dabbing brush.
The steel rods work through the heads of the brackets fitted to the dabbing
brush apparatus and over the brackets is fitted a plate or cover which is secured in
position by bolts or nuts. The slot hole in the light metal frame or casting allows
of regulating the stroke of the dabbing brush according to requirements.
We also employ a shoe or dabbing brush carrier of peculiar construction by which
we are enabled to lower the dabbing brush when required as it becomes worn. For
this purpose we make the shoo or dabbing brush carrier with lugs or loops on its
upper part by which it is attached to the light metal frame by means of bolts and
nuts, one of the bolt holes being elongated sufficiently to allow of the adjustment
of the dabbing brush. By the employment of light steel or iron tubes as herein-
before described we are able to produce a very light dabbing brush apparatus
which can be run at a much higher rate of speed, with less expenditure of power
with a steadier motion and with less wear and tear than is the case with the cast
iron and other heavy kinds of apparatus hitherto in use.
In order to enable our Invention to be fully understood we will proceed to
describe the same by reference to the accompanying Drawing in which Figure 1, is
a side elevation of a dabbing brush apparatus constructed according to our
Invention. Figures 2, and 3, are front elevations and Figure 4, is a side elevation.
Similar letters in all the Figures represent similar parts.
A, is the dabbing brush which is attached to the supporting shoe B, by screws
in the ordinary manner, the supporting shoe B, is attached to the light iron or steel
slide C as in Figures 1, and 2, or direct to the moving tubular pillars F, F, as in
Figures 3, and 4, by bolts passing through slots at D, D, to allow of adjusting the
brush and of lowering it when it becomes worn.

page_text: The light steel or iron frame C, to which the dabbing brush shoe is attached has
on either side a tubular pillar F, F, passing through guides G, G, as in Figures 1,
and 2, or where the dabbing brush shoe is attached directly to the bottom of the
pillars as in Figures 3, and 4 and no framework or slide between them is required
they are secured together at the top by the crosshead G, and pass through guides
at E, E which may surround the tubes F, F, to hold them steady on all sides or
may be in the form of a half circle holding each tube on one side only.

In Figures 1, and 2, the stud or pin Ñ is fixed in the driving pulley O, as far
from the centre thereof as is required to give the necessary length of stroke and
works in a friction roller or block fitting in the link at L. The revolution of the
driving pulley O, by these means gives the required up and down motion to the
link L, and to the slide C, to which it is attached.
In Figures 3, and 4, the eccentric K, working on a stud screwed or rivetted to
the driving pulley O gives the required up and down motion to the pillars F, F,
to which the eccentric is coupled at the joint L, thereby actuating the dabbing
brush.
By constructing the moving portions of dabbing brush apparatus of tubular
wrought iron or steel as herein before described we produce lightness with great
strength and by hardening or tempering the steel we ensure great durability of the
working parts.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
The employment of hollow steel or wrought iron tubes or hollow pillars to form
guides for the up and down motion of dabbing brushes the said tubes or hollow
pillars being attached to the dabbing brushes in the manner substantially as
hereinbefore described and represented in the accompanying Drawing.
