A MACHINE FOR TEAZLING OR RAISING A NAP ON WOOLLEN FABRICS
Year: 1885

page_text: I, GUSTAV RIEDEL, in Hof Bavaria in the Kingdom of Bavaria do hereby
declare the nature of my said invention for "A MACHINE FOR TEAZLING OR RAISING
A NAP ON WOOLLEN FABRICS and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:-
"
The purpose of this invention is to be able to put the rough cards or metal cards
bedded on the cylinder into any position required whilst working the machine so
that the stuffs to be carded by the metal cards are more or less worked upon
according to wish. In all teazling-machines used as yet an alteration in the
position of the cards can only be effected by putting in a new set of clothing
whose cards are in the position required; many teazling-machines of older con-
struction require even for every position of the cards particular machines. The
construction represented in Fig. 1 of the accompanying design shows a cylinder
with the aforesaid improvements in longitudinal section.
The card-holders a, a, a, (Figs. 5 et 6) are secured by means of studs b, b, b, to
the fillets cc (Figs. 5 et 6) and the latter are fixed in corresponding grooves of the
boards or beams d composing the cylinder to move backwards and forwards.
A tire A of equal diameter with the cylinder rests on the shaft B of the cylinder
and is connected with all fillets c c arranged on the circumference of the latter.
In the nave of this tire is a circular groove e into which the two trunnions catchi
that the one end of the fork-shaped angle-lever f terminates in. The second arm
of this lever is connected with a screw-spindle g. In order to produce a momentary
change in the position of all cards fastened to the cylinder the spindle g is merely
to be screwed up by the hand-wheel h, whereby the angle-lever draws the tire A
forwards and all other fillets cc secured to the latter follow this motion (figs. 2
et 3).
The under part of the card-holders a, a, a, fastened to the fillets is carried
forward by the fillets, whereas the upper part of them is guided by a stud i into
a slanting groove o.
The card-bolders a, a, a, thus carried forward by the fillets cc are moved from
the position shown in fig. 5 to that in fig. 6.
For the purpose of moving forward the tire A and the fillets cc the spindle y
can be used in the manuer drawn in the upper half of fig. 4.-In this case the
screw-spindle g is attached revolving on to the tire A forming the skeleton of the
cylinder, the thread of it runs in a broader place of the tire A movable on
the shaft B; by turning the hand-wheel wedged on to the spindle g the tire Aan.l
with it the fillets cc fastened to it are shoved backwards and forwards. In order

page_text: to prevent a one-sided motion of the tire A in using this last construction instead
of one spindle g two or more are employed which are fixed diametrically opposite
each other.
A third arrangement for displacing the card-holders fixed on the fillets_cc_is
shown by the lower half of Fig. 4 in side-view and figs. 5 et 6 in upper view. In the
latter arrangement the hand-wheel h, spindle g & likewise the tire A are dispensed
with; but in it however the fillets can only be displaced singly. In this construc-
tion the fillets c c terminate in a round screw k, on which a thumb-screw / provided
with a circular groove n moves. A stay m fastened to the boards & of the
cylinder D catches into this groove and when the thumb-screw is turned holds
the latter in one and the same position and forces the fillet c to a forward or backward
motion. The turning-point of the single card-holders a, a, can also be displaced
to the centre; in that case the slit o is replaced by a round hole is used through
which the peg i forming the axle is passed. Both ends of the card-holders are
fastened on to the fillet c by studs 66 and thus they are compelled to follow every
motion of the fillet. The alteration of the card-holders can be effected by a joint-
piece fastened movably to card-holder a and connected with the fillet c instead of
by the long slit o and the one stud i.
The metal-cards bedded in the card-holders, which can be made in any desirable
round or angular shape consists of the shaft r which is covered over with leather,
caoutchouc, india-rubber, cloth or other stuffs. Into this the teeth made of round
or flat metal-wire are stuck like the bristles of a broom.
The shaft of the cards made of wood or iron can be composed of two halves; in
this case a ring is put on to each end of the shaft to keep the two halves fast
together. The cards revolve round their own axes the leather rubber or other
. kind of cover, into which the teeth are fixed may be composed of one piece only,
or of 2 or 3 pieces, which are jammed in between corresponding parts of the shaft
for the cards.
The teeth are arranged parallel to the axis of the cards. In order to exchange
in case of need and with ease the cards w fastened revolving to the card-holders a,
one of the two stays ppl of the card-holder is provided with a revolving plate q
(fig. 8.) which prevents the card-shaft from falling out of the stays p p. The
insertion of the card into the card-holder in this case is as follows: the plate q
having been put in the position shown in Fig. 8 the card-shaft is put into the
perforations of the broad stay p, and the other end of the shaft r put into the
bore-hole reaching half through the narrower thickness of the stay. Thereby
the shaft remains at the other end so far back that the plate q can be shoved
forward again against the shaft r will knock, so that a forward motion of the card
is no longer possible; a click-spring t prevents the plate q from falling back.
In taking out the card w the spring t at the eye vis pressed to such an extent,
that plate
can pass and move sideways. The card-shaft r is then shoved so far
forwards till it can first be taken out of the stay p¹ and then out of stay p.
In order when carding light stuffs to prevent their adhering to the cards the
inventor fixes removable protection fillets between the card-holders.
Fig. 2 shows front view of this improved carding-machine.

fastened to the latter; the upper arrangement shows the construction by which the
displacement of all the fillets can be effected by means of spindle g & tire A,
whereas the lower arrangement represents the construction by which the displace-
ment of single fillets cc can be effected by means of thumb-screw etc.
Fig. 5 is the upper view of the card-holders arranged on the cylinder.
Fig. 6 shows the altered position of the card-holders a, a, produced by displace-
ment of the fillets c c.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1.) In a teazling machine the arrangement of a tire A bedded on the shaft B of
the cylinder, which serves for the forward and backward motion of the fillets cc
fixed on to the cylinder and connected in a suitable manner with the tire.
2.) The combination of the groove e fixed to the tire-nave A with the angle-
leverf in such a manner, that the lower leg of the latter catches into the groove e
with its two trunnions provided with rollers; further the combination of the
leverf with the spindle g through the upper leg of the lever ƒ for the purpose of
being able to move the tire backwards and forwards.
3.) The arrangement of two or more spindles g (fig. 4.) catching direct into the
tire to enable the latter to be pushed backwards or forwards as required.
4.) The arrangement of the displaceable fillets cc on the mantle surface of the
cylinder; and the manner of fastening the card-holders on to the fillets, either with
joint-pieces or without them, only on one or on both ends of the card-holders.
5.) For the requisite displacement and guidance of the card-holders in their
motion the employment of a slit o in the latter, into which the stud described
catches.
•
6.) The employment of a plate q on the card-holders fastened to fillet c to protect
the cards from falling out.
7.) The arrangement of removable, protection fillets between the card-holders in
order to prevent when carding light materials the adhering of the latter to the
card-holders.
8.) The manufacture of metal cards consisting of the wood or metal shaft r
made of one, two or more pieces, which is covered with leather, caoutchouc or fibre
stuff, and into which the cards of metal wire of round or angular shape and bent
in the long line of the shaft r are put like bristles.
9.) The manner of fastening the leather, caoutchouc or fibre-stuff cover on the
shaft w composed of one or more parts, by which the cover is jammed in between
the parts of the shafts, and the securing the parts of the shaft together by putting
rings on both ends of it.
