Improvements relating to Carding Engines.
HAROLD HOWARD OPENSHAW of Mossfield, Bury, Lancaster Mill Manager'do
hereby declare the nature of this invention to be as follows :-
-
That I have fixed in a suitable manner underneath the carding engine one or
more traversing endless latice or latices formed of bars or netting of wire or any
other suitable material passing over two or more rollers, shafts, or pulleys driven
in a manner and speed suitable to this invention which said traversing latice or
"
"waste which may
latices are fixed for the purpose of collecting or catching any
fly away from the cards during the process of carding and which said traversing
latice will feed a roller covered with cards (which roller forms part of the inven-
tion) and fixed in a position and driven at a speed suitable to this invention and
which said roller will feed in turn the cylinder or swift of the carding engine in a
regular and even manner with the "waste" collected from the traversing latice.
The latice will also separate the "dirt" from the wool in the "waste by
allowing the said "dirt" to pass through the bars or meshes of the said traversing'
latice; this also forms part of my invention.
'
I claim by the foregoing apparatus to be able to effect a saving of "waste
the process of carding.

F HAROLD HOWARD OPENSHAW, of Mossfield, Bury, in the County, of
Lancaster; 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 and accompanying drawings :-
―
My said invention relates to improvements in carding engines and has for its
chief object to prevent waste by collecting or arresting fibres which may leave or
fly away from the carding cylinder during the process of carding and returning
the same to the cylinder.
While providing for this prevention of waste my invention at the same time
permits of the separation of dirt from the fibre.
The invention will be more easily understood by a reference to the annexed
drawing which I'will now proceed 'to describe.
In the said drawing the circular curve a represents the periphery of the main cylinder
of a carding engine. The card dents are indicated on a portion of this periphery.
Beneath the carding cylinder a I arrange an endless travelling lattice 6 composed of
a number of cross bars; or wire netting, or other suitable flexible and open material
may be used, the said lattice being carried at each end on rollers or pullies ec¹ the
shafts of the said rollers or pullics being carried in bearings in the brackets d d'
the brackets being made adjustable by means of the screws e so that the lattice
can be drawn as tight as requisite. The lattice is driven in the indicated direction
LD

page_text: at any desired speed from a suitable part of the engine. At the front end of the
lattice I place a roller covered with cards the periphery of which grazes or just
clears the end of the lattice and also the periphery of the card covering of the
main cylinder a. This roller is carried on a shaft which is supported in
bearings in brackets g which slide vertically on side standards h and are adjustable
by means of set screws i. The position of the side standards h is also rendered
adjustable horizontally by means of the screws j. The roller f revolves in the
indicated direction, being driven from some suitable part of the engine. The
described apparatus operates in the following manner. When the engine is put
to work and all of the parts are in motion, the fibres which fall or fly from the
lower part of the carding cylinder a drop upon the travelling lattice 6 and are
thereby arrested, collected and carried forward to the transferring roller f. The
dirt which drops from the cylinder a falls between the cross bars of the lattice or
through the netting or other open or pervious material of which the lattice is
composed. Thus the dirt is separated from the fibre.. As already said the fibre is
carried forward by the lattice to the revolving roller which picks up the fibre
from the lattice and transfers it to the main cylinder a by which it is carried
forward to be again subjected to the carding means. Thus the fibre which would.
have otherwise been waste is restored to the carding cylinder while at the same
time the dirt is effectually got rid of. 1 thus both prevent waste and promote
more clean and effective carding.
The apparatus which I have illustrated and described is susceptible of modifica-
tion to some extent. For instance instead of the roller f I might have a small
travelling card lattice. I consider that the essence of my invention is the
employment of a travelling lattice placed beneath the carding cylinder and..
adapted to arrest and hold the fibre while letting the dirt go, free, the said lattice..
working in combination with suitable means for transferring or restoring the fibre
to the main carding cylinder.
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 :-
1. In carding engines or apparatus, the employment of an endless lattice of
cross bars or other suitable open work or material, mounted to travel beneath the
main carding cylinder, and operating in combination with a transferring roller or
lattice, whereby the waste fibre falling from the carding cylinder and arrested by
the travelling lattice is returned to the main cylinder, with the results that
waste is prevented while dirt is got rid of, all substantially as described and as
illustrated..
2. As means for preventing waste in carding engines or apparatus the travelling
lattice of the indicated nature in combination with the carding cylinder a
and the transferring roller for its equivalent substantially as described and.
shown.
