Improvements in the Method of and Apparatus for Regulating the
"Drag" on the Fibre under Operation on Finishing and Roving
Boxes and Analogous Machines.
1, ALFRED BINNS, of No. 14 Rose Terrace, Hanson Lane, Halifax, in the County of
York, Managing Overlooker, do hereby declare the nature of this invention to be as
follows:-
This invention relates to certain improvements in Finishing, Roving, and other
analogous machines used for the manipulation and reduction of fibre previous to it
being spun into yarn; and has for its object, the construction of an apparatus by
which, an easy and effectual adjustment of the "drag" may be accomplished to suit
the nature of the fibre and the thickness of the thread or cord on leaving the front
rollers of the respective machines.
I accomplish my object in the following manner :-Upon the lifter plate and around
each spindle I place a circular plate, in which are formed through the same two or
more grooves or openings, in each of which is secured a narrow piece of leather or
other flexible material, the same when in working position resting on the lifter plate
or on a flange thereon.
Each bobbin rests on one of the before mentioned circular plates, the latter being
rotated by frictional contact with the bobbin, so that, by moving the said pieces of
leather or other material towards or from the centre, as may be found necessary, more
or less power is required to drive the circular plate, thus regulating the drag
accordingly.

"Drag" on the Fibre under Operation on Finishing and Roving

I, ALFRED BINNS, of No. 14 Rose Terrace, Hanson Lane, Halifax, in the County of
York, Managing Overlooker, 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 certain improvements in finishing, roving and other
analogous machines used for the manipulation and reduction of fibro previous to it
being spun into yarn; and has for its object, the construction of an apparatus by
which the necessary "drag" on the fibre may be easily obtained, and readily adjusted
to suit the nature of the fibre and the thickness of the thread or cord leaving the front
rollers of the respective machines; and consists in forming a circular plate of wood or
other suitable material with two or more narrow slots or openings through the same,
and in each slot securing, on the side next the lifter plate, a piece of leather or other
flexible material, that by the weight of the bobbin resting on the said circular plate,
the leather or flexible material is pressed on the lifter plate, so that on moving the
said material from or towards the centre, more or less "drag" is obtained.
In describing this invention more in detail, reference is made to the accompanying
sheet of drawings, on which Fig. 1 represents a section through a portion of a roving
or analogous machine with a bobbin supported by one of my drag plates; Figs. 2 and 3,
views of the top and bottom sides of a plate showing how they may be constructed
when three slots are formed therein; Fig. 4, an edge view of the same; Figs. 5, 6
and 7, similar views of a plate with two slots; and Fig. 8, a section through one of
the arms, drawn to a larger scale.
In the centre of each "drag" regulating plate A, is a hole, through which an
ordinary spindle S is placed, the circular "drag" plate A resting upon the lifter
plate P in the manner as hereafter described.
Each "drag" plate A may be arranged with two or more slots B, through each of
which is passed a screw C, for securing a piece of leather or other flexible material D
on the opposite or under side next the lifter plate P, upon which the leather or other
flexible material rests.
Upon each spindle S, and resting upon the "drag" plate A is a bobbin F, the
weight of which causes the said plate to revolve by frictional contact therewith, and
by the leather or flexible material rubbing against the surface of the lifter plate P, the
same resists or retards the free motion of the plate A and bobbin F thereon, in
proportion to the distance the said pieces of leather or flexible material D, are from
the centre of the plate A; so that by the adjustment or securing of the said pieces D
in various parts in the slots, the necessary resistance or "drag" required for the class

page_text: of fibre and thickness of cord leaving the front rollers may be obtained, and adjusted
to the various requirements more expeditiously, and effectually, than by the means
now in common use.

It will be obvious to persons skilled in the art of preparing and spinning fibrous
materials, that the necessary drag may be produced by making the drag
plate A without slots, and glueing or otherwise securing the small circular pieces of
leather or other flexible material D to the said "drag" plate, the necessary distance
from the centre; which operation or system is not so advantageous for regulating, as
when slots are provided, but will accomplish my object in obtaining the "drag" equally
as well, but the adjustment of the said pieces D is more difficult."
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 :-
A plate to which are attached two or more pieces of leather or other flexible
material D, for the purpose of producing and adjusting the necessary "drag" on the
fibre between the nip of the front rollers and the rotating bobbins on the spindles of
finishing, roving, and analogous machines, all being arranged substantially in the
manner as herein before described.
