Combing Fibrous Substances.
LOUIS EDMUND PRIESTLEY Card Maker and GEORGE FREDERICK PRIESTLEY, Card
Maker, Hope Street Halifax Yorkshire, do hereby declare the nature of this invention
to be as follows:-
29
A spiral coil or twist is given to each side or "leg" of a tooth used in carding
or combing fibrous substances, in order to give greater elasticity in working.
This coil or twist is situated between the "crown and bend" of each tooth.
The "crowns" of the teeth are afterwards placed in slots sawn in a wood foundation
and a wire is then placed or threaded thro' each coil in order to support the tooth
and make all of an uniform height.
These wires are fastened to the end of the wood foundation in any suitable manner
to give rigidity.

LOUIS EDMUND PRIESTLEY, card maker & GEORGE FREDERICK PRIESTLEY card
maker Hope Street Halifax, Yorkshire 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 all kinds of Cards, Combs, Hackles and other teeth used.
in the carding, combing and straightening of Fibres, such as Flax Hemp, Jute, Silk
and Tow, and is described as follows.
1st. Steel Teeth having coils or twists on each leg.
2nd. A foundation, preferably of wood with or without sawn longitudinal
slots.
3rd. A wire or other material running thro' if desired each coil or twist to support
it in its position.
4th. The spacing of the teeth by means of Beads or perforated plate, in one
direction, and in the other direction by putting the crowns of the teeth in slots, or by
useing flattened wires. On each leg of the card tooth, a coil or twist is made between
the crown and bend which twist can be either made right or left hand optionally.
These teeth when hardened and tempered are then placed optionally in slots
sawn in a wooden foundation, so that the teeth assume a slightly vertical position.
When the various rows are completed, a wire or other material is threaded through
each coil or twist if desired, and held fast in a suitable manner at each end of the
card or foundation.
In order that each tooth be equidistant from its neighbour in useing the aforesaid
wire, a bead is threaded on the wire between each tooth, and this gives the required
spacing.
The teeth may be hardened and tempered or left in a soft condition if desired.
To space the teeth lengthways of the Card, a perforated metal sheet may be used
having slots in it the width of the card and placed over the teeth above the
coils.

page_text: To space the teeth the width way of the card when useing the perforated plate, we
place flattened pieces of wire between each tooth below the coil.
In order that our Invention may be fully understood and readily carried into effect,
we will proceed to describe the accompanying sheet of drawings, reference being
had to the figures and letters marked thereon.
Figure I is an end elevation of our improved card for carding or combing fibrous
substances.
Figure 11 is a side view of the tooth.
Figure III is the same as figure I but shewing the use of slots in the wooden
foundation in lieu of flattened pieces of metal as in Figure I.
Figure IV is a plan or top view of the wooden foundation shewing the slots cut in
the foundation, and the position of the metal plate.
In Figure V, shews the method of spacing the teeth by means of beads, and a
wire running through the coils.
In figure I A are the strips of flattened metal to space the teeth the width way
of the card.
In Figure III & IV Bare the slots cut in the foundation F to space the teeth in
another manner the width way of the card.
In figure I, II & III, C shew the curls or coils in the teeth.
In figure I, II, III & IV D shews the metal plate to space the teeth the length-
way of the card."
In figure II & IV E are the slots in the plate D.
In figure I, III & IV F is the wooden foundation.
In figure I, II & III G are the legs of the tooth.
In figure II, H is the crown of the tooth.
In figure II & V K is the wire running thro' the coils of the teeth if Beads are
used.
In figure V, L are the Beads, an alternative means of spacing the teeth length-
way of the card to that done by the plate D.
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:-
1st. Teeth made of Iron or Steel wire having a coil or twist on each leg between
the crown and "bend."
"
وو
2nd. A foundation of wood having optionally slots sawn in longitudinally in
which the " crowns "of the teeth are inserted.
3rd. The novelty of running a wire or other substance through each of the coils
of such teeth to hold them in position.
4th. The novelty of spacing the teeth by means of beads the lengthway of the
card.
5th. The novelty of placing a perforated metal plate over the teeth to space them
and hold them in position.
6th. The novelty of spacing the teeth the width way of the card by means of
flattened wires below the coils of the Teeth.
