I, JAMES WALLACE Junior 15 Brookhill Avenue in the Borough of Belfast, in the
County of Antrim, Ireland Mill Manager do hereby declare the nature of this
invention to be as follows:-
:―
It is an extension of the invention for which Provisional Protection was granted
8th Feby., 1887 No. 1935 and relates to the "Rubbers" used in keeping rollers or
bosses in a clean condition.
These rubbers as at present used in the Preparation and Spinning of Flax, Cotton
and other fibrous materials are constructed of flannel fastened to either revolving
bosses or stationary pieces of metal, wood, or other suitable material, and are
allowed to lie on, or are pressed against, the rollers requiring cleaning. They,
getting dirty themselves, allow some of the dirt to pass into material, thus making
dirty yarn.
I propose to obviate the passing of dirt into material, and also lessen labor, by a
new self cleaning rubber which I accomplish in the following manner :-In applying
it to the "Pressing" rollers of preparing machinery, I connect rollers or bosses of
metal or other suitable material (I shall call them Rubber Rollers") to a driving
shaft, by movable arms. Round these rollers, and bosses on driving shaft, I place a
driving belt, and a belt of flannel or other suitable material. Near the driving shaft
1 place a brush or equivilant cleaning apparatus also a trough in a suitable position to
retain any droppings from brush. Thus the flannel in its traverse round "Rubber
Roller is brought into contact with "Pressing Roller" hence it proceeds round the
boss on driving shaft where it comes in contact with brush and is cleaned before going
again to pressing roller. I may convey the rotary motion to "Rubber Rollers" by
gear or any other known means.
"
I prefer the above method of applying the brush to the rubbers of "Pressing
Rollers" but I may, without violating the conditions of my invention, apply a brush

of rubbers.
shaft or having a separate brush for each rubber or
pair
In applying my invention to the "Boss Roller" I cause the flannel belt to pass
round a shaft under Boss roller and hence to a brush, the belt being kept from
"Fallers" by guide pulleys. By causing the flannel to pass over a bar thus bringing
it close to the fallers in their descent from top to bottom slide it may also be made to
clean the fallers. In a similar manner the flannel band may be applied to the
"Retaining" rollers and to the rollers of spinning frames.

Improvements in Preparing and Spinning Machinery.
I, JAMES WALLACE Junior, of 15 Brookhill Avenue, in the Borough of Belfast, in
the County of Antrim, Ireland, Mill Manager, 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:-
My invention relates to machinery for preparing and spinning flax, cotton and
other fibrous materials, and more particularly to the "rubbers," cleaners or clearers
used in such machinery for keeping the rollers or bosses in a clean condition and
preventing the adherence thereto of loose fibres.
The said rubbers, cleaners or clearers, as at present used, are made of flannel
fastened to either revolving bosses or stationary pieces of metal, wood or other
suitable material, and are allowed to lie upon, or are pressed against, the rollers or
bosses which require cleaning. The said rubbers, when thus arranged, are liable to
become dirty and to allow some of the dirt to pass from them into the material being
operated upon, so that soiled and lumpy yarn is produced by the machine.
My invention is designed to obviate this defect and to diminish the labor_required
in keeping the machine in proper order. To accomplish these results, I employ
rubbers, cleaners or clearers consisting of travelling bands or belts of flannel or other
suitable material, and I provide means for automatically cleaning the said rubbers,
cleaners or clearers as hereinafter described.
My said invention may be conveniently and advantageously applied to a roving-
frame as illustrated in the accompanying drawing, which is a sectional elevation.
A is part of the frame of the machine. B is one of the pressing-rollers, and (one
of the boss-rollers.
I employ, in combination with each pressing-roller B, a roller a of metal or other
suitable material, which I will hereinafter term a rubber-roller, and which is carried
by arms & pivoted upon a driving shaft c, so that the said rubber-roller will rest upon
the presing-roller B, with freedom of movement towards and away from the axis of the
said roller B to accommodate itself to any inequalities in the diameter of this roller.
A boss c is fixed on the driving shaft c and around the roller a and boss c' is passed a
leather or other driving belt d and a band or belt e of flannel or other suitable
material, which forms the rubber, cleaner or clearer. These belts work in grooves in
the said roller a and boss c', or other convenient means are employed for keeping them
in the required track. Near the driving shaft e I place a brush or other device for
cleaning the band or belt e and keeping the flannel rough. The flannel does better
work when rough. With the ordinary rubbers, or without a brush, it soon gets
smooth. The axle of the brush is mounted in slots in the frame, and any
convenient means is provided for adjusting it towards or away from the belt e. I also
provide a trough g or other receptacle in a suitable position to catch and retain any
droppings from the brush f. The flannel e, as it travels around the rubber-roller a,

page_text: rubs against the surface of the pressing-roller B and acts very efficiently in removing
the loose fibres, gum, dirt and the like therefrom. It then passes to, and is acted
upon by the brush, whereby it is cleaned, as it travels around the boss c', before
again acting upon the pressing roller B. The requisite motion may be imparted to
the driving shaft c and to the rubber-rollers (if necessary) by means of gear-wheels or
in any other convenient manner.
In applying my invention to the boss-roller C, the flannel or other belt e is passed
around a revolving roller beneath the boss-roller C, and under guide pulleys or
rollers, h², and around a roller h³ so that it is kept free from, or clear of the fallers.
A brush is arranged in combination with tho said belt, and a trough gl or other
receptacle is, if desired, placed under this brush to catch and retain the dust. The
lower belt e, moreover, serves to carry away the droppings from the fallers and deliver
the same into this trough or receptacle, I sometimes provide a rod i against which the
bristles of the brush will strike and thus have the dust removed therefrom.
It is not essential that a driving belt should be used in combination with the rubber-
band or belt; one belt may, if desired, be made to serve both purposes.
Although I have hereinbefore described ny said invention more particularly as
applied to the pressing-rollers and boss-rollers of machinery for preparing and
spinning flax, it is obvious that the said invention is also applicable to the retaining-
rollers or other rollers in such machinery and also to the rollers of spread-boards,
drawing-frames, spinning-frames and the like.
My said invention affords the following advantages, viz.:-Tho machinery can bo
-driven at a higher speed than heretofore, as there is less lich-up." There is less
waste, less labor and the yarn is cleaner and more valuable than with the rubbers
ordinarily used. And, in many cases, no washing of the rollers is necessary.
Having now particularly described and ascertained the nature of my said
invention and in what manner the samo is to be performed I wish it understood
that I claim-
In machinery for preparing and spinning flax, cotton and other fibrous materials:-
First. The employment of a rubber, cleaner or clearer consisting of a travelling
band or belt of flannel or other suitable material, substantially as, and for the purpose,
set forth.
Second. The employment of a travelling band or belt for carrying away the
droppings from the fallers and delivering the same into a trough or other receptacle,
as above specified.
Third. The combination, with the travelling band or belt, of one or more brushes or
other means for automatically cleaning the said band or belt, substantially as, and for
the purpose, set forth.
Fourth. The employment of a trough or other receptacle for catching and retaining
the droppings from the brush, as above specified.
