IMPROVEMENTS IN AND RELATING TO DABBING BRUSHES EMPLOYED IN WOOL COMBING MACHINERY
Year: 1884

page_text: We, HOWARD PRIESTMAN of Ashfield Mills Bradford, in the County of York,
Spinner and Manufacturer, and JOSEPH ROBERTSHAW of N° 12 Grange Terrace,
Allerton, near Bradford aforesaid, Manager do hereby declare the nature of our
invention for IMPROVEMENTS IN AND RELATING TO DABBING BRUSHES EMPLOYED
IN WOOL COMBING MACHINERY," to be as follows:-
This Invention has special reference to the dabbing brush employed in wool
combing machinery; but more particularly when applied to "Noble's " machine
where the fibre is forced into the teeth at the tangent of two rotating combs.
In practice it is found that these brushes wear away quicker at one part than
at another, and in order to compensate for this, the worn part of the brush is
sometimes packed, so as to slightly tilt the brush to bring the bristles level with
the points of the comb teeth, but in doing so, the said bristles are thrown out of
parallel with the comb teeth, consequently there is objection to this, and therefore
brushes have to be thrown away when one part thereof is in good working
condition.
To avoid this is the object of our Invention, which we accomplish by making
the dabbing brush in two parts, and fastening each part to separate foot brackets,
so that when one brush is worn before the other, it can be reset and adjusted
without disturbing the other brush, by which means a considerable saving is
effected over the present brushes.
COMPLETE SPECIFICATION.
We, HOWARD PRIESTMAN of Ashfield Mills, Bradford, in the County of York,
Spinner and Manufacturer, and JOSEPH ROBERTSHAW of 12, Grange Terrace,
Allerton, Dear Bradford aforesaid, Manager do hereby declare the nature of our
invention for "IMPROVEMENTS IN AND RELATING TO DABBING BRUSHES EMPLOYED
IN WOOL COMBING MACHINERY" and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
This invention has special reference to the dabbing brush employed in wool
combing machinery, but more particularly when applied to "Noble's" machine
where the fibre is forced into the teeth at the tangent of two rotating combą

page_text: In practice it is found that these brushes wear away quicker at one part than
at another, and in order to compensate for this, the worn part of the brush is
sometimes packed, so as to slightly tilt the brush to bring the bristles level with
the points of the comb teeth, but in doing so the said bristles are thrown out of
parallel with the comb teeth, consequently there is objection to this, and therefore
brushes have to be thrown away when one part thereof is in good working
condition.
To avoid this, is the object of our Invention, which we accomplish by making
the dabbing brush in two parts and fastening each part to separate brackets,
so that when one brush is worn before the other, it can be reset and adjusted
without disturbing the other brush, by which means a. considerable saving is
effected over the present brushes.
Such being the nature and object of our Invention, we will now proceed to
describe the accompanying Sheet of drawings which illustrates our improvements.
A is the usual reciprocatory slide, at the foot of which is attached the dabbing
brush by screws or bolts. In our case the dabbing brush is composed of two
parts B and C, the part B being secured to the foot of the slide A, whilst
the part C is secured to an adjustable bracket D, such bracket being connected
to the bottom of the reciprocatory slide A, by bolt and nut E.
As the brush C operates upon the teeth of the two combing circles at the
point of contact or tangent of the circles, it is well understood that this brush
wears away much quicker than the brush B, in order therefore to compensate for
this as the bristles get shorter by working, we have made provision for lowering
the brush C, which is easily done by slackening the nut E and operating the nut F
on the vertical screw G, by which means the bracket D can be lowered and
accurately adjusted to suit the varying length of bristles, and when the brush is
worn away it can be re-placed by another one without disturbing the brush B,
consequently a saving of brushes is effected as will be at once understood.
Fig 1 shews plan of the brushes, and Fig 2 shews plan of brushes divided to
suit broad combs, we do not however limit ourselves to the way in which the
brush is divided, as that will vary according to circumstances.
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 two dabbing brushes, one of which can be adjusted for
purposes substantially as herein shewn and described.
