Improvements in or applicable to Rag Engines.
I JAMES REDFORD Managing Director of The Greenfield Mills Company
Limited, and ROBERT HARRISON Foreman Bleacher, both of Greenfield Mili,
Greenfield near Oldham in the County of York, do hereby declare the nature of
this invention to be as follows :-
This invention relates to machines known as rag engines used for bleaching and
cleaning cotton waste and other fibrous materials; it is also applicable to the rag
engines used for tearing and cleaning rags in the manufacture of paper.
The object of our invention is to provide automatic means for discharging the
fibrous material after it has been sufficiently treated in the rag engine, thereby
saving the time and labor required to remove the said material by hand.
The invention consists in mounting near to the "weir" over which the fibrous
material is thrown by the "rag-roll "a travelling band lattice or "creeper" carried
in a frame which can be let down in close proximity to the said weir when
required so that the fibrous material can be projected thereon and carried away
thereby.
"
out of
The frame carrying the "creeper" is provided with suitable counterbalance
weights and other appliances for raising and lowering the said "
into position as required.

COMPLETE SPECIFICATION.
Improvements in or applicable to Rag Engines.
We JAMES REDFORD Managing Director of The Greenfield Mill Company
Limited and ROBERT HARRISON Foreman Bleacher both of Greenfield Mill,
Greenfield near Oldham in the County of York, 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 :-
66
This invention relates to machines generally known as rag engines," used for
washing bleaching and cleaning cotton waste and other fibrous material, it is also
applicable to the rag engines used for tearing cleaning and washing rags in the
manufacture of paper.
The object of our invention is to provide automatic means for discharging the
fibrous material after it has been sufficiently treated in the rag engine, thereby
saving the time and labor required to remove the said material by hand.
The invention consists in mounting near to the "weir" over which the fibrous
material is thrown by the "rag-roll" a travelling band, lattice, or "creeper" carried
in a frame which can be let down in close proximity to the said weir when
required so that the fibrous material can be projected thereon and carried away
thereby.
The said invention will be readily understood on reference to the accompanying
sheet of drawings and the following explanation thereof.
Fig. 1 is a sectional elevation and Fig. 2 a plan view of a rag engine with our
improvements applied thereto. a is the weir, b the rag roll, c is the travelling
lattice or 66 creeper "carried in a frame d which swings upon a shaft e.
The creeper shewn on the drawings is composed of laths of metal or wood
ID 7

page_text: carried upon straps or belts c¹ running over pulleys upon the shaft e; this shaft e
is driven by a pulley e² and the shaft e' is driven from the shaft e by the chain e³
and chain pulleys on the said shafts.
The frame d'is attached at f to a chain g which passes upwards over suitable
pulleys not shewn and is weighted at the other end to counterbalance the said
framed which can thus be readily raised into the position shewn by the dotted
lines when the engine is cleansing the rags, waste or other fibrous materials, or
lowered into the position shewn by the full lines when it is required to discharge
the fibrous material.
When the creeper c is in this latter position, as the rag-roll 6 revolves in the
direction indicated by the arrows it throws the fibrous material over the weir a and
upon the creeper c, the direction of motion of which is also indicated by arrows;
the creeper c thus carries away the material thus projected thereon and discharges
it into a trolley as shewn dotted at or merely upon the flooring outside the
engine.
By these means we are enabled to empty the engine in less than one minute.
We would remark in conclusion that other conveyors may be used instead of the
lattice or creeper shewn.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
The combination with the "weir" of a rag engine of a lattice or creeper or
equivalent conveyor so mounted that it can be raised from the weir when the
engine is at work or, lowered to remove the contents thereof substantially as
herein before described.
