Complete Specification Left, 27th June, 1894-Accepted, 28th July, 1894
⚫ PROVISIONAL SPECIFICATION.
Improvements connected with Rag Engines.
I, JAMES MITCHELL, of Rawtenstall, Lancashire, Cotton Waste Bleacher, do
hereby declare the nature of this invention to be as follows:-
The improvements relate to what are known as rag engines, for the cleansing
and washing of cotton waste, or other fibrous material, or for the washing,
cleansing, and tearing up of rags for paper manufacture; and such improvements.
have for object the removal of the fibrous material from the apparatus, after
treatment, by automatic means.
In rag engines as at present, for the most part, ordinarily employed, the cotton
waste, rag, or other fibrous material is repeatedly beaten about in a tank, along
with water and other cleansing agents, by means of a drum known as the
rag roll," and when sufficiently cleansed or treated, is withdrawn from such tank
by hand.
66
To accomplish the object of my improvements, I mount upon or near the tank,
and in front of the drum or rag roll, an inclined guide frame, or it may be
frames, sloping downwards towards the drum, and projecting over or near that
portion of the tank called the weir.
Upon this guide frame or frames I then mount a travelling web, band, lattice .
or other creeper, in such manner as to enable the said creeper to freely slide to
and fro thereon; and also, by preference, the creeper is so mounted as to be
capable of swivelling vertically upon its point or points of connection with the
frame or frames, so as to enable it to move as hereinafter described.
The upper end of this creeper is connected, by swivel joint, to one extremity
of a link, which link is similarly connected, at its other extremity, to a fixed centre,
and is capable of oscillating vertically in a plane parallel to the plane of motion of the
creeper. Thus, when this link is moved, the travelling creeper is forced along its guides
into close proximity with the rag roll, to receive the treated material thrown
forward thereby, or is withdrawn from that position, clear of the tank, to an
almost horizontal position.
The web, band, or lattice of the creeper may be driven by any suitable means,
and the oscillating link may receive its motion, from the operator, by rack and
pinion, lever, or other mechanism; likewise, in lieu of one oscillating link, two or
more may be employed, and other variations in detail may be made, without
departing from the peculiar character of the invention.

COMPLETE SPECIFICATION.
Improvements connected with Rag Engines.
I, JAMES MITCHELL, of Rawtenstall, Lancashire, Cotton-waste Bleacher, do
O 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:-
The improvements relate to what are known as rag engines, for the cleansing

and tearing up of rags for paper manufacture; and such improvements have for
object the removal of the fibrous material from the apparatus after treatment, by
automatic means.
In rag engines as at present, for the most part, ordinarily employed, the cotton
waste, rag, or other fibrous material is repeatedly beaten about in a tank, along
with water and other cleansing agents, by means of a drum known as the
rag roll," and when sufficiently cleansed or treated, is withdrawn from such tank

To accomplish the object of my improvements, I mount upon or near the tank,
and in front of the drum or rag roll, an inclined guide frame, or it may be frames,
sloping downwards towards the drum, and projecting over or near that portion of
the tank called the "weir."
Upon this guide frame or frames I then mount a travelling web, band, lattice or
other creeper, in such manner as to enable the said creeper to freely slide to and
fro thereon; and also, by preference, the creeper is so mounted as to be capable
of swivelling vertically upon its point or points of connection with the frame or
frames, so as to enable it to move as hereinafter described.
The upper end of this creeper is connected, by swivel joint, to one extremity of
a link, which link is similarly connected, at its other extremity, to a fixed centre,
and is capable of oscillating vertically in a plane parallel to the plane of motion of the
creeper. Thus, when this link is moved, the travelling creeper is forced along its
guides into close proximity with the rag roll, to receive the treated material thrown
forward thereby, or is withdrawn from that position, clear of the tank, to an almost
horizontal position.
The web, band or lattice of the creeper may be driven by any suitable means,
and the oscillating link may receive its motion, from the operator, by rack and
pinion, lever, or other mechanism; likewise, in lieu of one oscillating link, two or
more may be employed, and other variations in detail may be made without
departing from the peculiar character of the invention.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by mne.

But when it is desired to withdraw the material, the handle v..
is operated, and the
creeper drawn to the position shewn in dotted lines.
The rag roll then projects its load upon the creeper, which carries forward the
rags or waste, and deposits the same in any suitable receptacle; most of the liquid
thrown up being allowed to escape, through the lattice spaces or otherwise.
The lattice may be continually travelling, whether the creeper is in or out of
operation, or motion may be given thereto at the same time as the creeper is.
entirely moved towards the weir.
I am aware that travelling creepers have been employed for the purpose of
removing material from rag engines after treatment, such creepers having been put
in and out of operation with a single radial motion, and fulcrumed at a fixed
point in front of the weir; but such are entirely different from this my present
invention, wherein the creeper is withdrawn by a compound motion from the weir,.
when not in use, and so removed from the stream projected by the drum, thereby
preventing interference with the free working of the rag engine.
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 :-
In rag engines for the cleansing and washing of cotton waste, or other fibrous.
material, the employment of a travelling creeper, fulcrumed at one end upon
oscillating links or levers, and capable of being withdrawn from a position in front.
of the weir to a second position removed therefrom, for the purpose and in manner
substantially as herein shewn and described.
