PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Opening Out or Straightening and
Clearing Fibrous Material.
I, DAVID BLACK, of 22, Springcliffe, Manningham, Bradford, in the County of
York, Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object, the arrangement of an apparatus by which
fibre may be straightened or opened out and the knotty portions removed therefrom,
whilst passing through preparing and combing machines; and to so arrange the
apparatus that the knots and other matter removed are automatically deposited in
a suitable receptacle and that the action of the working parts are not so noisy as
when screw gill fallers are used for the purpose.
I accomplish my object in the following manner:-Around the inner circum-
ference of the rim of a cylinder, I mount a number of bars, each bar having a
series of pointed pins secured thereto which engage with corresponding holes
through the cylinder rim; the ends of the bars are supported by cams, so that, on
the cylinder rotating, the bars are moved in accordance with the cams, by which
the pins are caused to project through the holes in the rim or retire at the required
time.
By the projecting pins passing through the fibre, it is straightened and opened
and the knotty and other hard matter removed therefrom, which is carried away
by the pins and released on the withdrawal of the pins, thus allowing the extracted
knots and other matter to fall into a suitable receptacle.
Bars are placed across the outer circumference of the cylinder. between each
series of pins, by which the fibre is not allowed to come in contact with the circum-
ference of the rim, and by the first mentioned bars working in and supported by
the before named cams, the action is comparatively noiseless.
Dated this 24th day of March 1892.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Opening Out or Straightening and
Clearing Fibrous Material.
I, DAVID BLACK, of 22 Spring Cliff, Manningham, Bradford, in the County of
York, 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 has for its object the arrangement of an apparatus by which
fibre may be straightened or opened out and the knotty portions removed therefrom
whilst passing through preparing and combing machines, and to so arrange the
apparatus that the knots and other matter removed may be automatically
deposited in a suitable receptacle.
In order that my invention may be fully understood I will describe the same in
detail by making reference to the accompanying sheet of drawings in which
Fig. 1 represents a plan view of a portion of a preparing or combing machine
with my improvement attached.
Fig. 2 a section of same through line a. b. and

page_text: and indicated by the letter A. On to the bed plate B. I mount in suitable
journals C. C. a cylinder D. composed of a number of perforated plates. In the
inside of said cylinder D. I mount a number of moveable bars E. having their
respective ends E' prepared to engage with the slides F. formed in each end
plate G. of the cylinder D. On to each end of the before mentioned bars E. I
mount a bowl or runner R. To the before-mentioned journals C. C. I secure the
stationary cam plates H. H. having a path H¹ in and around which the bowls or
runners R. travel when the cylinder D. is rotating. By the path H¹ of the cam
plate H. being of an eccentric form as shewn, the bowls or runners R with the
bars E secured thereto, are caused on the cylinder D. revolving to move towards
and away from the centre of the cylinder, whereby the pins J secured to bars E
are automatically caused to pass through corresponding holes in the plates
forming the outside circumference of the cylinder, and to engage with the fibre
at the point X, straightening the same and removing therefrom any knotty or
foreign substance, and by the cylinders travelling in the direction of arrow, the
matter removed from the fibre is carried round on the revolving cylinder D, and on
the pins J automatically and successively retiring to the inside of the cylinder
release their hold of the matter removed from the fibre when the same may be
stripped from the cylinder by means of a doffer or stripping roller and deposited in
any suitable receptacle.
In order to prevent the fibre from coming in close contact with the outer circum-
ference of the cylinder D. I place the bars K. across the same between each series
of pins J.
It will be easily understood that the pins J may be arranged to pass through
the cylinder at the opposite angle to those shewn, when the cylinder rotates in
the opposite direction to suit the requirements of the preparing or combing
machine.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The combination of the parts forming the cylinder with a preparing or
combing machine arranged substantially in the manner and for the purpose herein-
before described.
2. The bars E and bowls or runners R in combination with the bars K on the
circumference of cylinder and the stationary cam plates H. H. arranged sub-
stantially in the manner and for the purpose hereinbefore described.
