Improvements in Combing Machines.
I, JOHN CHARLES WALKER, trading as John Perry of Shipley Fields Mill, Shipley
in the County of York, Mechanical Engineer, do hereby declare the nature of this
invention, to be as follows:-
This invention relates to that class of combing machines in which dabbing brushes
are employed for pressing the wool into the teeth of the combs.
66
Instead of using the dabbing brush for dabbing the wool down to the pin points,
and in place of blades or knives for forcing the wool down into the pins separately or
in conjunction with the dabbing brush, I press the wool into the combs in the following
manner-At the tangent point of the comb circles where the operation known as
dabbing" takes place, I press the sliver down to the points of the pins by means of
suitably shaped plates or blocks provided with a reciprocating motion, these plates or
blocks are caused to move downwards as near as possible to the pin points without
touching or entering between them, the completion of the movement of the sliver into
the pins is effected by a suitable dabbing brush. The aforesaid plates are driven
separately from the dabbing brush, and the stroke, thereof may when required be of a
variable character.

Improvements in Combing Machines.
I, JOHN CHARLES WALKER, trading as John Perry of Shipley Fields Mill, Shipley
in the County of York, Mechanical Engineer, 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 :-
This invention relates to that class of Combing machines in which dabbing brushes
are employed for pressing the wool into the teeth of the combs.
In the accompanying drawings, Fig. 1 is a front elevation with front plate removed,
and Fig. 2 is a transverse section of dabbing brush motion. Fig. 3 is a plan of
dabbing brush, all shewing my improvements applied thereto.
Instead of using the dabbing brush A for dabbing the wool down to the pin points B,
and in place of blades or knives for forcing the wool down into the pins separately or
in conjunction with the dabbing brush A, I press the wool into the Combs in the
following manner;-At the tangent point of the comb circles where the operation
known as "dabbing" takes place, I press the sliver down to the plates B of the pins
by means of suitably shaped plates or blocks C, to which a reciprocating motion is
imparted from an eccentric D on the dabbing brush motion shaft E, such motion being
transmitted thereto through connecting rod F and crosshead or arm G, which is
steadied or directed by guide rods H. These plates or blocks C are caused to move
downwards as near as possible to the pin points B without touching or entering
between them, thus carrying the wool or sliver with them, after this the completion of
the movement of the sliver is effected by the dabbing brush A in the ordinary way.
The stroke of the plates C may when required be capable of adjustment.
Other parts of the dabbing brush motion not described may be of ordinary
construction.
By the application of the aforesaid plates or blocks (a great quantity of work is
taken from the dabbing brush A, thereby much reducing the wear and tear thereof.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The arrangement and application of plates or blocks C for pressing the sliver or
wool down to the points B of the pins, either separately or in conjunction with the
dabbing brush A, substantially as and for purposes herein set forth.
Dated this 22nd day of November 1888.
