Improvements in Scutchers and Lap Machines.
I, JAMES HUGHES, of 22, Clarendon Street, Sandy Lane, Reddish, in the County
of Lancaster, Carder, do hereby declare the nature of my said invention to be
as follows:
This invention relates to improvements in scutchers and lap machines and
has for its object to provide means whereby the dirt expelled from the fibres
under treatment is continuously and automatically removed from under the dirt`
grid, employed between the beater and cage and thus the said grid prevented from
being chocked up and the dirt mixing with the fibres again.
To this end my invention consists in employing below the said dirt grid an
endless apron furnished with ribs arranged at suitable distances apart from cach
other and forming spaces for the reception of the dirt which falls from the
said grid.
The said apron is mounted upon rollers one of which is suitably rotated and
imparts motion to the apron.
In order to prevent the current of air drawing the dirt from the said apron,
a flexible flap, say of leather, is employed at each end of the apron, one of the
said flaps being arranged above and the other below the apron in accordance with
the direction in which it moves.

Improvements in Scutchers and Lap Machines.
I, JAMES HUGHES, of 22, Clarendon Street, Sandy Lane, Reddish, in the County
of Lancaster, Carder, 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 relates to improvements in scutchers and lap machines and
has for its object to provide means whereby the dirt expelled from the fibres
under treatment is continuously and automatically removed from under the dirt
grid, employed between the beater and cage and thus the said grid prevented from
being chocked up and the dirt mixing with the fibres again.
And in order that my invention may be more fully understood I have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.

page_text: Fig. 1 is a side view partly in section of a scutcher or lap machine showing
my improvements applied and Fig. 2 a plan thereof.
In carrying out my invention and referring to the figures generally, the im-
provements consist in employing below the said dirt grid a an endless apron b,
say of canvas, furnished with ribs c, arrangel at suitable distances apart from
each other and forming spaces d for the reception of the dirt which falls from
the said grid.
The said apron is mounted upon two rollers e, f, one of which, say e is suitably
rotated and imparts motion to the apron b, and is supported at each edge, say
by pieces of angle iron and kept at a tension by the roller h.
The said pieces of angle iron reach from roller to roller and beside serving
as supports keep also the chamber b¹ above air tight.
By preference I rotate the said apron intermittently, say from the top cage
wheel, by furnishing the latter with a stud, which strikes once every
revolution against a pawl lever thereby operating a ratchet wheel having
secured to its axis a chain wheel m from which motion is transmitted by means
of the chain to another chain wheel secured upon the end of the roller
shaft e, whilst the fulcrum of the said pawl lever is provided with a back pawl q
to prevent the chain wheel turning back.
In order to prevent the current of air drawing the dirt from the said apron,
a flexible flap m', m', say of leather, is employed at each end of the apron 6 to
bear against the same, which close the chamber b¹ at each end to allow of the
ribs e passing in and out.
The dirt falling from the grid a is thus constantly or at short intervals moved
from underneath the grid by the apron and discharged below the latter.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. In scutchers and lap machines, in combination with the grid a, an endless
travelling apron employed below the same and furnished with ribs e forming
spaces for the reception of the dirt falling from the said grid, all substantially
as and for the purpose set forth.
2nd. In scutchers and lap machines an endless travelling apron b, c, d below
the grid a, in combination with leather or other suitable flaps m', m' arranged
at each end of the said travelling apron, all substantially as and for the purpose
set forth.
