PROVISIONAL SPECIFICATION.
Improvements in Scribbling or Carding Machines.
1, GEORGE MARTIN, of 62, Hawkshead Street, Southport, in the County
of Lancaster, Agent, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in scribbling or carding machines
particularly applicable for carding wool and similar fibres, and its object is to more
efficiently open out and straighten the fibres and at the same time reduce the
liability to break them.
"
For this purpose I employ one or more sets of revolving flats as workers in
connection with one or more of the "swifts or "cylinders" of the machine. The
flats of each set are connected together in the usual manner and they are mounted
upon discs and star wheels fixed upon an adjustable cross shaft driven in any
convenient way.
As the flats revolve past the swift or cylinder they are guided
in a path more or less parallel to the periphery of the swift or cylinder by means
of either adjustable stationary or rotary guides fixed more or less between the said
discs and star wheels and the swift or cylinder. The backs of the flats bear against
the guides and there is an adjustable curved guide at each end for the ends of the
front of the flats to revolve upou. The whole of these guides may be connected
together so that they may be simultaneously adjusted and the bearings of the said
cross shaft may be capable of independent adjustment.
By this arrangement the flats may be so adjusted in relation to the swift or
cylinder that as they pass its periphery they gradually approach nearer to it conse-
quently any sudden action is avoided and the tendency to break the fibres is reduced
to a minimum.
Two or more of these sets of flats may be employed in connection with each
swift or cylinder, and the said card clothing of the different sets may vary in
count.
A "stripper" may be provided to remove the fibres from the flats as they leave
the swift or cylinder. This stripper may be arranged to be thrown out of action
and the flats stripped as they approach the swift or cylinder and the fibres deposited
upon the latter so that they pass beneath the flats again.

Improvements in Scribbling or Carding Machines.
I, GEORGE MARTIN, of 62, Hawkshead Street, Southport, in the County
of Lancaster, Agent, 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 scribbling or carling machines
particularly applicable for carding wool and similar fibres, and its object is to more
effectually open out and straighten the fibres.

page_text: To fully describe my invention reference is made to the accompanying sheet of
drawings forming a part of this Specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, represents such parts of a carding machine as are necessary to illustrate
the application of my improvements.
Figure 2, represents a section of the same on the broken line a, b of the former
figure. In this figure the full width of the machine is not shown as one side is
practically the same as the other.
Figure 3, represents a view of a detail hereinafter referred to.
A portion of the side frame of the carding machine is represented by the letter A
and is the crown of what is commonly called the "bend" of the fame and B represents
a portion of one of the "swifts or cylinders.
"
A casting C is fitted to the "bend" A on each side of the machine. In the
drawings it is shown fixed between the webs A 2, A 2 of A by the set screws C2 and
it is also secured by the bolts C 3, C 3. An adjustable fixing D is secured to each of
the castings C by the bolts D2, D2 and adjusting screws D3, D3 are fitted in the
fixings to engage the bolts D2 to facilitate adjustment. A bearing piece E is
secured on each side by a bolt E2 to the fixing D and this bearing piece is made
vertically adjustable. Each bearing piece is provided with a U shaped bearing
at the top in which the shaft F extending from one side of the machine to the
other is mounted. This shaft is driven in any convenient manner but preferably
by a belt or chain. A star wheel G of the usual form to receive the projections H
on the ends of the flats H 2 is fixed in position close to each end of the shaft an la
disc J is also secured on the shaft adjacent to each star wheel. These discs are
provided for the backs H 3 of the ends of the flats to bear upon and so relieve the
pressure and friction on the teeth G 2 of the star wheels. A curved guide
piece K is fixed by the adjustable studs K 2, K 2 inside each of the fixings D.
Screws K 3, K3 are fitted into the slots D5, D 5 in D to facilitate adjusting the
studs K 2. The flats are connected together in the usual way by the chain L
connected by the screws L 2 to the end faces of the projections H.
The shaft F is driven in the direction of the arrow Figure 1 and the flats
pass off the disc J under the guide piece K which are so formed and adjusted
that the card teeth H 4 on the flats gradually approach the card teeth B2
of the cylinder B consequently any sudden action on the fibres is reduced to
a minimum.
To ensure a smooth and uniform action it is of the greatest importance that the
backs of the flats should be held firmly and squarely against the guide pieces K
whilst they are acting upon the fibres. Therefore besides keeping the chins
at a suitable tension the under guides N are provided on the inner face of
the fixing D. The upper or guide faces of the guides N are parallel to the
guides K and are exactly the thickness of the ends of the flats away from the
acting faces of the guides K consequently the flats are held with the requisite
degree of firmness and truth whilst they are acting on the fibres. Figure 3,
represents a separate side view of one pain of guides K, and N with the ends of
the flats shown between them.
The fixings D and the parts connected to them may be bodily adjusted to
regulate the position of the Hats in action on the fibres in relation to the switt
cylinder B.
Two or more of these sets of flats may be employed in connection with one swift
or cylinder and the card filleting with which the flats of the different sets are
covered may vary in
66 Cont "that is to say in the number and strength of the
"dents or wire points.
"
A "stripper" S is shown in Figure 1 on each side of the flats mounted in bearing
pieces S2 secured in the fixing D. It is not necessary to use the two strippers but
one may be used in either position. The bearing pieces S also serve to carry
grinding rollers.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. In a scribbling or carding machine, the combination with the revolving flats of
the guide pieces K and N, substantially as herein shown and described and for the
purpose specified.
2. In a scribbling or carding machine, the combination with the revolving flats
of the guide pieces K and N, and the disc J, substantially as herein shown and
described.
