PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
We, THOMAS ROTHWELL, Mill Manager, and JOHN WILLIAM ROTHWELL, Fitter,
both of Rose Cottage, Edge Lane Road, Oldham, in the County of Lancashire, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in carding engines and has for its object to
provide means whereby a better result in carding fibres and extracting impurities
therefrom is obtained and the card clothing is more preserved than heretofore has been
the case.
Our invention consists principally in the employment in connection with the takerin
of one or more toothed or spiked bars, which have the combined action on the fibres,
of a bar and comb. The respective teeth or spikes, in one or more rows, may either
be fitted into or formed on the edge of the bar and below the same which presents
itself to the takerin. The said teeth or spikes are set or formed on the bar at an acute
angle to the periphery of the takerin, each row being longer than the preceding one.
The bars at each end are carried by means of a bracket fixed adjustably to the side
frame of the carding engine, so as to permit of bringing the edge of the bar and teeth
or spikes nearer to or further away from the periphery of the takeriu.

COMPLETE SPECIFICATION.
Improvements in Carding Engines.
We, THOMAS ROTHWELL, Mill Manager, and JOHN WILLIAM ROTHWELL, Fitter,
both of Rose Cottage, Edge Lane Road, Oldham, 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 carding engines and has for its object to
provide means whereby a better result in carding fibres and extracting impurities
therefrom is obtained and the card clothing is more preserved than heretofore has been
the case.
Our invention consists principally in the employment in connection with the taker-in
of one or more toothed or spiked bars, which have the combined action on the fibres,
of a bar and comb. The respective teeth or spikes, in one or more rows, may either
be fitted into or formed on the edge of the bar and below the same which presents
itself to the taker-in. The said teeth or spikes are set or formed on the bar at an
acute angle to the periphery of the taker-in, each row being longer than the preceding
one.
The bars at each end are carried by means of a bracket fixed adjustably to the side
frame of the carding engine, so as to permit of bringing the edge of the bar and teeth
or spikes nearer to or further away from the periphery of the taker-in.
And in order that our invention inay be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Figs. 1 & 2 are both vertical sections of the taker-in and the bars employed in
connection therewith showing our invention carried out in various ways.
a is the taker-in, 6 the feed plate, c are the bars or knives, d the teeth or spikes.

page_text: In carrying out our invention, we employ one or more toothed or spiked bars or
knives c, as shown in Fig. 1, provided or formed with teeth or spikes & at an acute
angle to the taker-in, in the direction in which the taker-in and the fibres run, as
shown by the arrow. The said bars or knives e are suitably carried by means of a
bracket e bolted to the frame side f. The said teeth or spikes d, which may be applied
to the said bar or knife c in any suitable number, increase in length in the direction
the fibres and taker-in run, and instead of being fixed or formed on the bar or knife c
itself, as shown in Fig. 1. they may be formed or fixed on a bar g secured to the bar
or knife c, as shown in Fig. 2, which bar g we preferably make of wood. The bar or
knife c to which the tooth or spike bar g is secured may be of the section as shown in
full lines, or as shown in dotted lines in Fig. 2, or of any other suitable section. The
action of the teeth or spikes d on the fibres as they pass over then disintegrate the
loose and short fluffy fibres and cause them to fall away into the dirt box. They also
break up what is commonly known in roller and cleaner cards, as butterflies, and pass
the fibres in a longitudinal form, so that the cylinder receives it straight on. the end
ready for its first roller or flat, thereby making much better carding and cleaner
work.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
"In carding engines."
.
1st. The general construction and adaptation of bars or knives, provided with teeth
or spikes, operating substantially as and for the purpose specified.
2nd. The bar or knife c, or a separate bar g secured thereto, provided or formed
with teeth or spikes d, which incline in the direction in which the taker-in and the
fibres run, substantially as and for the purpose specified.
