the Empire of Austria, for the Invention of "IMPROVEMENTS IN
TEASLING APPARATUS."
Sealed the 30th July 1875, and dated the 21st May 1875.
COMPLETE SPECIFICATION filed by the said Moritz Wolf Fürth at
the Office of the Commissioners of Patents, with his Potition and
Declaration, on the 21st May 1875, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MORITZ
WOLF FÜRTH, of Strakonitz, Bohemia, in the Empire of Austria, send
greeting..
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN”.
TEABLING APPARATUS," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn Declaration that I am the true and
first Inventor thereof.

page_text: NOW KNOW YE, that I, the said Moritz Wolf Fürth, do hereby
declare that the following Complete Specification, under my hand and
scal, fully describes and ascertains the nature of tho said Invention, and
in what manner the same is to be performed, in and by the following
statement :-

This Invention relates to a system of rotary metallic teasels, by which
the dressing, raising, or finishing of cloth of every description and degree
of fineness can be effected more rapidly and with a less expenditure
of power than with ordinary vegetable teasels, which, owing to their
inferior durability and bellied shape, cannot be employed in this way. 1
The rotation of each separate teasel around its own axis is effected
by the friction of the cloth which is being teasled, and in a very short
working time a denser and woollier nap is produced on the cloth than
can be made with ordinary teasels..
The teasels of this construction may, on account of their greater 1
durability, be regarded as a permanent part of the gig mill. They are
not liable to injury from the moisture of the cloth treated, and therefore
can work continuously without requiring to be dried. An economy in
working time is thereby effected and no reserve teasels are needed.
These metallic teasels may be applied to any simple form of teasler.or. 2
gig machine, without requiring special alterations in the machinery.
The attendance is the same as in an ordinary gig mill, and the capacity
of a machine with one gig barrel fitted with these teasels, is much
superior in economy of time and power to that of an ordinary double:
barrelled gig. The cloth is also dressed much better, and the loss of hair 2
and the consequent deterioration of quality is much less than in ordinary
teasels. The cleansing of these teasels can be effected more quickly and
easily without removing them from the gig barrel..
.
In teasling velvet cloth neither an apparatus for cross teasling nor any
other expensive apparatus are required, and the process carried out is a
a very simple.one.
With the rotary teasels the thickest cloths may be teasled as well as
the thinnest, without danger of their being torn through. The rotary
teasel. consists of circular metal discs formed with radiating points, the
extreme ends of which are bent over to a hooked shape.

page_text: The discs are fixed upon a metal sleeve, cach of them being separated
•
from the next by a washer placed between, or by a projection formed on.
them. The first and last discs are supported by end discs which are
fastened to the sleeve, all of these. discs being secured against turning on
the sleeve by means of a rib fitting into notclies in the disc, or by other
suitable means. Tlie discs are mounted in such a manner on the sleeve
that the position of the hooks of the one disc alternates with that of
those of the next following disc.
.
The teeth of the teasle are formed with a rib so as to be of a V shape.
in cross section, making them similar to the teeth of natural teasels.
The teasels may be made of any required degree of fineness and
.elasticity.
These teasels being of metal cannot be as soft and yielding as vegetable
teasels, and would consequently be unfit for teasling every kind of cloth,
unless made to give way under undue pressure. For this purpose each
teasel is mounted on a special apparatus, permitting its yielding both
longitudinally and vertically. This apparatus consists of a wooden or
iron frame with a spindle resting at each end on a spiral spring. This
spindle passes through the artificial teasel and through a spiral spring
pressing against one end of the teasel. These springs allow the teasel
to yield vertically and longitudinally, and thus prevent the cloth being
torn through in case of the teasel being pressed too strongly against it.
The construction of the teasling apparatus is fully illustrated in the
accompanying Drawings.
Fig. 1 shews a side elevation of the teasel mounted on its frame, the
former being partially represented in longitudinal section, a, a, and
b, b, being the discs; Fig. 2 is a top view of the samẹ.

substantially as described and for the purpose described, or any colourable
imitation thereof.

In witness whereof, I, the said Moritz Wolf Fürth, have hereunto
set my hand and seal, this Fourth day of May, in the year of our 5
Lord One thousand eight hundred and seventy-five.
