IMPROVEMENTS IN DABBING APPARATUS EMPLOYED IN COMBING WOOL AND OTHER FIBROUS SUBSTANCES
Year: 1884

page_text: We WILLIAM TERRELL GARNETT, of the firm of William Garnett and 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
and 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 further improvements in the "dabbing" apparatus
employed in combing wool and other fibrous substances described in our Provisional
Specification dated the fourteenth day of February 1884 Number 3312. In the
said Provisional Specification we described the shoe for carrying the dabbing
brush as fixed to two steel rods or tubes which passed through bosses or guides
which held them in position while working.
Our present improvements consist in attaching the supporting shoe of the
dabbing brush to a light wrought iron or steel slide having a hollow tubular guide
at each side truly bored out and parallel with one another. These tubular guides
work upon wrought iron or steel tubular pillars which are fixed by a strong
crosshead bolted to the framework or upright column of the combing machine.
In the slide is formed a slot hole through which is passed a bolt securing a sector
to the wrought iron or steel slide. In the sector works a steel friction roller or
block with a pin working in it. In this steel roller is placed a stud or pin having
a collar and fixed to the driving pulley of the dabbing apparatus. This pin or
stud on which works the friction roller is fixed sufficiently out of centre on the
driving pulley to give the necessary length of stroke which length of stroke may
be varied by moving the pin or stud nearer to or further from the centre of the
driving pulley and securing it with a nut. Near the bottoms of the wrought iron
or steel tubular pillars are recesses into which flows the superfluous oil used for
lubricating them and the oil is sucked up by the up stroke of the guides.
The shoe of the dabbing brush is fitted on to a frame which is secured to the
slide by bolts passing through slotted holes and can be so adjusted to the dabbing
brush as to allow for the wear of the brush.
By constructing the working parts of the dabbing brush apparatus of wrought
iron or steel we secure lightness with great strength enabling us to work at a
great speed with less expenditure of power and inore steadiness.

Barkerend Road, Bradford, Yorkshire, Spinners, and JOHN WHEATER, Engineer,
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

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 further improvements in the dabbing apparatus
employed in combing wool and other fibrous substances described in our Provisional
Specification dated the fourteenth day of February 1884, Number 3312. In the
said Provisional Specification we described the shoe for carrying the dabbing
brush as fixed to two steel rods or tubes which passed through bosses or guides
which held them in position while working.
Our present improvements consist in attaching the supporting shoe of the
dabbing brush to a light wrought iron or steel slide having a hollow or tubular
guide at each side truly bored out and parallel with one another. These tubular
guides work upon wrought iron or steel tubular pillars which are fixed by a strong
crosshead bolted to the framework or upright column of the combing machine.
In the slide which supports the shoe of the dabbing brush is formed a slot hole
through which is passed a bolt securing a sector to the wrought iron or steel slide.
In the sector works a steel friction-roller or block with a pin working in it. In
this steel roller is placed a stud or pin having a collar and fixed to the driving
pulley of the dabbing apparatus. This pin or stud on which works the friction
roller is fixed sufficiently out of centre on the driving pulley to give the necessary
length of stroke which length of stroke, may be varied by moving the pin or stud
nearer to or further from the centre of the driving pulley and there securing it
with a nut,
Near the bottoms of the aforesaid tubular pillars are recesses into which flows
the superfluous oil used for lubricating them and the oil is sucked up by the up
stroke of the guides.
The shoe of the dabbing brush is fitted onto a frame which is secured to the
slide by bolts passing through slotted holes and can be so adjusted to the dabbing
brush as to allow for the wear of the brush,
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 Figures 1,
and 2, are elevations of dabbing brush apparatus constructed according to our
Invention Figure 3, part back view and Figure 4, part side sectional 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 fixed upon the light wrought
iron or steel slide C, by bolts passing through slotted holes D, D, to allow of the
adjustment of the brush and of lowering it as it becomes worn.
E, E, are the hollow or tubular guides one on each side of the slide C, and
working upon the upright tubular pillars F, which are joined together and held in
position by the strong crosshead G, by which they are firmly secured to the
framework or upright column H, of the combing machine.
In the slide C, is formed a slot hole J, through which is passed a bolt K, securing
the sector or curved link L, to the slide C. In the sector works the friction
roller M, or a block fitted in the sector may be used. The sector being attached

page_text: to the slide C, imparts to it the up and down motion it receives from the pin or
stud carrying the friction roller L, and which pin or stud N, is secured to the
driving pulley O, at a sufficient distance from its centre to give the necessary
stroke to the dabbing brush and this stroke may be varied by the adjustment of
the pin or stud which is held in position by a lock nut or may be permanently
screwed or riveted to the driving pulley.
Near the bottoms, of the tubular pillars are recesses which are filled by the
superfluous oil running down into cups P, formed at the bottom of the pillars and
of the same diameter as the pillars so that the guides can pass over them and
which in their upward stroke suck up a supply of oil thereby keeping the pillars
lubricated.
By communicating motion to the sector having the centre from which it is
struck downwards, the commencement of the down stroke is made slowly and the
commencement of the upward stroke very quickly which is an advantage in the
operation of "dabbing."
By constructing the working parts of the dabbing brush apparatus of tubular
wrought iron or steel as hereinbefore described we secure lightness with great
strength enabling us to work at a great speed with less expenditure of power and
with more steadiness.
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:-
Firstly. In dabbing apparatus the employment of a light steel slide having
tubular wrought iron or steel guides at each side working or sliding upon and
being steadied by tubular wrought iron or steel pillars which act as slide bars to
the frame of the brush substantially as hereinbefore described and represented in
the accompanying Drawing.
Secondly. The method or means of communicating motion to the frame of the
brush by means of a pin or stud on the driving pulley and working in a friction
roller or block fitted into a sector which is attached to the frame carrying the
brush and the centre of which sector is at a point below it substantially as
hereinbefore described and represented in the annexed Drawing.
Thirdly. Forming oil-recesses or cups at the bottom of the slide pillars for the
purpose of lubrication substantially as hereinbefore described and represented in
the accompanying Drawing.
Fourthly. The method of attaching the dabbing brush shoe to the frame which
carries it by means of bolts working in slot holes so that the level of the brush can
be adjusted as required and as it wears as herein before described and represented
in the accompanying Drawing.
