PROVISIONAL SPECIFICATION.
Improvements in Opening, Scutching, and Carding Machines for
Cotton and other Fibres.
We, WALTER LORD, of the firm of Lord Brothers, of Canal Street Works,
Todmorden, in the County of York, Machine Maker, and THOMAS GANDY MILLS,
Manager, and SAMUEL NEWELL, Foreman, of the same place, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to improvements in opening seutching and carding
machines for cotton and other fibres and our improvements consist in a novel
method of mounting and adjusting the grids over which the fibrous materials pass.
In carrying our improvements into effect we mount each of the grid bars in
such a manner that the said bars can be oscillated or adjusted separately or
collectively so as to vary the position of the bars.
A convenient method of effecting this is to form a neb or pivot or projection at
each end of each grid bar and to support the rows of nebs in recesses in or on plates
rails or equivalents placed at the opposite ends of the grid bars.
Any convenient means of oscillating or adjusting the grid bars may be employed
such as a rack to which a reciprocating motion may be given either intermittently
or continuously by means of a chain wheel and eccentric stud or their equivalents,
the rack engaging either the upper or lower ends of the grid bars. The grid bars
may be supported in the side or end plates transversely longitudinally or diagonally
to the machine frame, and they may be so set that their upper surfaces present a
wavy or uneven surface to the cotton or other fibre passing over them.

COMPLETE SPECIFICATION.
Improvements in Opening, Scutching, and Carding Machines for
Cotton and other Fibres.
We, WALTER LORD, of the firm of Lord Brothers, of Canal Street Works,
Todmorden, in the County of York, Machine Maker, and THOMAS GANDY MILLS,
Manager, and SAMUEL NEWELL, Foreman, of the same place, 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 opening scutching and carding machines
for cotton and other fibres and our improvements consist in a novel method of
mounting and adjusting the grids over which the fibrous materials pass.
In carrying our improvements into effect we mount each of the grid bars in such
a manner that the said bars can be oscillated or adjusted separately or collectively
so as to vary the position of the bars.
A convenient method of effecting this is to form a neb or pivot or projection
at each end of each grid bar and to support the rows of nebs in recesses in or on
plates rails or equivalents placed at the opposite ends of the grid bars.
Any convenient means of oscillating or adjusting the grid bars may be employed
such as a rack to which a reciprocating motion may be given either intermittently
or continuously by means of a chain wheel and eccentric stud or their equivalents,
the rack engaging either the upper or lower ends of the grid bars; or the grid
bars may be adjusted to any desired angle and fixed in that position. The grid
[ Porce fid

diagonally to the machine frame, and they may be so set that their upper surfaces
present a wavy or uneven surface to the cotton or other fibre passing over them.
And in order that our invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig is a side elevation of part of an opening machine to which our improve-
ments are applied and
Fig. 2 is a cross section of part of the same.
Fig. 3 is a similar view to Fig. 1 but illustrating an alternative arrangement.
In these views a designates the heater, the cages c part of the machine franie,
and d the grid bars.
In the arrangement illustrated by Figs. 1 and 2 the grid bars have formed at
each end a neb or pivot by which they are supported in a recessed side plate or
rail which is secured to the machine frame in this way each grid bar d
hangs suspended from the nebs d'.
t
To oscillate or adjust the grid bars d we prefer to employ a movable rack near
ench side plate which rack engages in this case the upper ends of the grid bars d.
The rack (or racks if two are employed) is moved to and fro either intermittently
or continuously as required by means of the chain wheel g fixed on the axis of the
cages and driving by a chain a chain wheel with an eccentric stud ; which
engages a slot in the rack. By means of the reciprocating rack the grid bars d
may be oscillated continuously or may be adjusted and set so that their upper
surfaces present any desired angle to the fibre passing over them.
In Fig. 3 the arrangement is substantially the same as in the previous Figs. 1
and 2 but the form of the grid bars d is slightly varied and further we show an
adjusting rack farranged below as well as above the grid bars d.
It will be understood that we do not require racks both above and below but
that they may be employed either above or below and in either of the arrange-
ments Figs. I and 2 or Fig. 3.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
In opening scutching and carding machines-
1. Mounting the grid bars over which the fibrous materials pass in such manner
that the said bars may be oscillated or adjusted substantially as herein set forth.
2. The combination with the pivoted grid bars d, of the movable racks sub-
stantially as and for the purposes herein set forth.
