Year: 1880

page_text: LETTERS PATENT to James Webster, the younger, of Silver Royd Hill, Wortley,
near Leeds, in the County of York, for an Invention of "IMPROVEMENTS IN
APPARATUS EMPLOYED FOR CLEANING OR CLEARING CARDS USED IN THE
MANUFACTURE OR PREPARATION OF WOOL, SILK, OR OTHER FIBROUS
SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said James Webster at the Office
of the Commissioners of Patents on the 14th February 1880.
JAMES WEBSTER, the younger, of Silver Royd Hill, Wortley, near Leeds, in the
County of York. "IMPROVEMENTS IN APPARATUS EMPLOYED FOR CLEANING OR
CLEARING CARDS USED IN THE MANUFACTURE OR PREPARATION OF WOOL, SILK,
OR OTHER FIBROUS SUBSTANCES."
Cards whilst in operation collect or receive therein a quantity of dirt or extraneous
matter or useless material, which has the tendency to clog them up and cause them
to work imperfectly.
The object of my Invention is to clear or cleanse such cards from these obstruc-
tions, and for this purpose I apply to either of the "fancies," "angle strippers," or
ordinary" strippers" two card segments, which by a parallel motion can be made
to work evenly with the rest of the cards, or withdrawn below the level of such
cards, so as to be out of use entirely, or so projected that their teeth during their
rotary motion may work deeper into the other cards, and thus clear or cleanse them
of the accumulated dirt, extraneous matter, or material before referred to.
The required projecting and withdrawing motions are effected or obtained by set
screws or their equivalents, and are of the description known as parallel motion or
motions.

page_text: lever by the connecting rod or rods 8. It will be readily understood that by
turning the screw q motion is transmitted to the first lever i, which motion is con-
veyed to the other levers i through the connecting rod or rods 8, and by such
motion the segments or sliding pieces are moved outwards so as to project beyond
the carding for purposes herein set forth, or withdrawn to such an extent that it
or they may work in combination with the other carding, or withdrawn clear of the
work altogether.
Figs. 1, 2, 6, and 7 shew arrangements of cylinders having two segments or
sliding pieces; Figs. 3 and 4 shews arrangement of cylinder with only one sliding
piece or segment applied thereto. In order to fix the segments or sliding pieces in
any desired position I provide the stud t, which may be passed into the grooves or
teeth u formed in the disc v, which is pin'd or otherwise fixed on the regulating
screw q, thus retaining the screw in any desired position. A ratchet wheel and
pawl or other equivalent means may be employed for this purpose. I have lettered
the parts which are employed for one and the same purpose with corresponding
letters.
Having now described the nature of the said Invention, and described with the
aid of Drawings how the same may be carried into practice, I would have it under-
stood that I do not limit myself to the precise details or configuration of the parts
I have described and shewn, as the same may be varied or modified without departing
from the nature of my said Invention, but what I do claim and desire to be secured
to me by Letters Patent is,-
First. The arrangement, construction, and application of sliding pieces or segments
a and b, having carding fon cach of their surfaces, such segments or sliding pieces
being capable of adjustment so that the carding ƒ may be caused to project beyond
the carding for the purpose of collecting dirt or other useless material or matter
from the swift or other carded cylinder, substantially as herein set forth.
Second. The arrangement and application of the parallel motion and parts
connected therewith for adjusting the segments or sliding pieces a and b and
modifications of the same, substantially as and for purposes herein set forth.
In witness whereof, 1, the said James Webster, the younger, have hereunto
set my hand and seal, this Twelfth day of August, in the year of our Lord
One thousand eight hundred and eighty.
