Improvements in Apparatus for Feeding Wool or other Fibrous
Material to Carding Engines or other Machines.
We CHARLES STOTT of 276 Oldham Road Machinist and WILLIAM HENRY
SCHOFIELD of 339 Oldham Road Machinist both of Rochdale and County of
Lancaster, do hereby declare the nature of this invention to be as follows:-
Our invention relates to a device or arrangement for securing the lags or laths of
a travelling brattice or apron to the foundation or travelling band, but this invention
is more particularly adapted to be used in connection with the apron employed in
automatic feeding machines for feeding material to carding engines or other
machines, in such machines, the apron being situated in a certain position which
does not admit of easy access or ready removal, great difficulty is experienced
in consequence when a new lag or lath is required to be placed in position. It is to
obviate this difficulty owing to breakages etc. that our invention is designed, thus to
enable a lag to be inserted readily, and this without necessitating much trouble
to effect the purpose as is the case with the ordinary methods of securing the lags
or laths. It will be manifest from the description hereinafter contained, that this
invention may equally be employed in connection with the ordinary travelling
brattice or apron employed in connection with other machines or apparatus.
We will now proceed to describe our invention.
We employ a screw threaded piece or stud provided with a head which stud we
pass through the foundation or travelling band and cloth, also through the lag or
lath, the stud being of sufficient length so as to project above the surface of the lag,
and being screw threaded at its extremity for a convenient distance of its length, is
prepared to receive a plate or piece having an aperture provided with a corre-
sponding screw thread, which piece is of circular form, and is provided with holes,
nicks, or perforations, which are provided to receive the projecting points of a
suitable key, which piece allows-when the projecting points are inserted therein-
of being turned about the stud, at will, or accordingly as it may be desired to
screw or unscrew the piece or plate thereon or therefrom, consequently in the
former case the plate may be turned so as to firmly secure the foundation and the lag
together, in the latter case, to unscrew the plate therefrom, enabling the lag to be
removed as the case may be, and this whilst the travelling brattice or apron
remains in its working position.

Improvements in Apparatus for Feeding Wool or other Fibrous
Material to Carding Engines or other Machines.
We CHARLES STOTT of 276 Oldham Road Machinist and WILLIAM HENRY
SCHOFIELD of 339 Oldham Road Machinist both of Rochdale in the County of
Lancaster, 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 :-
Our invention relates to improvements in the feeding apparatus of carding
engines being a device or arrangement for securing the lags or laths of the travelling
brattice or feeding apron to the foundation or travelling bands upon which the said

page_text: laths are ordinarily mounted. Our arrangement is particularly beneficial when
employed in connection with automatic feeding machines for feeding fibrous material
to carding engines or other similar machines as in such machines the aprons may be
and are generally so situated as not to admit of ready or easy access when the
necessity arises for the renewal of a lath. The present mode of affixing or attaching
the lath to the foundation by means of rivets which are securely clinched at.
the upper or top side of the lath which mode of fastening or attachment is well
known this attachment in addition to the disadvantageous situation or position
before named renders the removal of a lath for the purpose of renewal a tedious
and oftentimes a difficult operation involving much loss of time and great
expenditure of labour which may be and is avoided by the use of our invention
which provides an expeditious means for applying or securing the lath to the
foundation. This invention may also be applied to or in connection with the
ordinary travelling brattice employed in connection with carding engines or other
machines, and to any feed apparatus having a brattice or travelling apron composed
of lags or laths.
In order that a clear understanding may be had of our invention we have reference
to the accompanying sheet of drawings in which like letters of reference indicate
like or similar parts throughout the figures therein shewn.
Fig. 1. represents a plan of our invention shewing a lath provided with steel
teeth or pins attached to or mounted upon the travelling bands or foundation.
Fig. 2. is a sectional elevation of Figure 1.
Fig. 3. is an elevation shewing the screw threaded stud detached from the lath
with its corresponding screw threaded nut or washer.
We according to our construction and arrangement employ a screw threaded
piece or stud a. provided at its lower side with a head a' which stud we pass
or insert through an aperture 6. provided or made in the bands or foundation
pieces c. the said studs also passing through corresponding apertures d. provided in
the lathe that is, -apertures opposite to the apertures b. provided in the foundation
or bands the said stud being of such a length so as to project above the upper
surface of the lath e. being screw threaded for a convenient distance of its length is
prepared to receive and is provided with a corresponding screw threaded piece
or washer f. provided at convenient parts with indentations or apertures g. which
are provided and arranged to receive the projecting points of a suitable key or
instrument the said washer may be turned at will about the axis of the stud by
means of the key accordingly as it may be desired to screw or to unscrew the lath on
or to remove it from its position or to screw or to unscrew the washer on to or from
off the stud a. the stud during such operation that is, when the washer presses or
impinges on the lath remains stationary or is prevented from turning round by
means of the raised parts or projections a' provided at the lower part a', con-
sequently when the studs are in position, any convenient number may be employed
according to the number of bands c.. employed and the washers adjusted on the
studs the lath may be thus firmly secured in position on the foundation or bands in
the latter event the unscrewing of the washer-the lath may be readily and easily
removed therefrom as occasion may require and these operations-the placing on
or removing of the lath from the travelling bands or foundation-may and can be
performed or exercised whilst the apron or brattice remains in its working position
therefore obviating the necessity as heretofore of removing or interfering with the
working position of the apron for the purpose of replacing a lath as in cases where
such apron is difficult of access, and when rivet fastenings are employed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is.
