TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
EDWARD YATES and HENRY YATES, both of Cleckheaton, in the County
of York, Card Manufacturers, and WILLIAM HEATON KELLETT, of
Liversedge, in the County aforesaid, Card-setting Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of April, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Edward Yates, Henry Yates,
and William Heaton Kellett, Her special licence- that we, the said
Thomas Edward Yates, Henry Yates, and William Heaton Kellett,
executors, administrators, and assigns, or such others as we, the said
Thomas Edward Yates, Henry Yates, and William Heaton Kellett,

page_text: our executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
5 Ireland, the Channel Islands, and Isle of Man, an Invention for "Iм-
PROVEMENTS IN WIRE CARDS AND IN THE MACHINERY OR APPARATUS USED IN THE
MANUFACTURE THEREOF," upon the condition (amongst others) that we,
the said Thomas Edward Yates, Henry Yates, and William Heaton
Kellett, our executors or administrators, by an instrument in writing
O under our, or their, or one of their hands and seals, should parti-
cularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same
to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters
3 Patent.
NOW KNOW YE, that we, the said Thomas Edward Yates, Henry
Yates, and William Heaton Kellett, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following state-
ment and accompanying Sheet of Drawings, that is to say:
-
This Invention relates to the construction of cards which are provided
with teeth having the working parts thereof flat or of other section, so
as to present a sharper point and working part to the fibre, being carded
without the said teeth having the defect of lateral weakness, as has been
the case with the teeth of cards heretofore constructed of flattened wire.
We accomplish our object by constructing the cards as follows:-The
wire to be employed in the manufacture of cards having the peculiar
teeth made according to this our Invention is rolled by the intermittent
action of the rolling apparatus herein-after more particularly described.
The wire is passed between squeezing or flattening rollers, and the
pressure on the rollers is obtained through the agency of a tappet or
other mechanical equivalent, which imparts the necessary intermittent
pressure. The result is that the wire passing between such rollers has
portions of its length flattened at intervals, the intervening length being
left round or of the original form or section of the wire. The wire so
prepared is then cut into the required lengths to form teeth, and is then
set, which may be done by the ordinary card-setting machines.

page_text: Proper care must be taken that the portion of the wire which is
flattened is made to form the upper portion or "working part" of the
card, whilst the round part of the wire or the part not altered in form
by rolling is that which is fixed or set in the cloth or material forming
the back of the cards, which round part may in practice extend to about 5
the "bend."
crown
"
It follows from the above description that cards formed of teeth made
from wire so rolled have the teeth strong and stiff in the parts where
such qualities are needed, being round from the "
to the
"bend," while the working parts are flattened, thereby ensuring the 1
advantages of the flattened working parts without having the disad-
vantage of lateral weakness, as is the case with cards heretofore in use
when made with teeth formed of wire wholly flattened, that is, flattened
throughout the entire length of the teeth.
Having now described the nature and object of this our said Invention 1
we will next proceed to describe the same in detail, and the manner in
which it may be beneficially carried into practice.
In order that the Invention may be clearly understood we have
hereunto annexed a Sheet of Drawings, and have marked the same with
figures and letters of reference, the same letter referring to the same
part in the various views or Figures.
i
Fig. 1 is a side elevation of the bed plate and driving shaft of an
ordinary fillet card-setting machine, which we provide with rollers and
apparatus for flattening the wire at intervals in the manner that makes
it suitable for being cut up into lengths to form the peculiar teeth
employed by us in our improved cards; Fig. 2 is a plan view of the
same drawn about half full size; Figs. 3 and 4 are details of some of the
parts thereof.
Fig. 5 is a view of a portion or length of wire specially rolled for
being cut up into lengths to form teeth of the required form or shape:

page_text: · A is the bed plate of an ordinary fillet card-setting machine; B is the
driving shaft; C and D are squeezing or flattening rollers, flattening
the wire at E at intervals, as it is drawn between them by the ordinary
"feed" mechanism (and which forms no part of this Invention), the said
rollers have intermittent rotary motion imparted to them by means of
the tappet F, which moves the lever G, to the loose end of which the pawl
or ratchet wheel lever H is attached. The other end of the pawl
engages with the teeth of the ratchet wheel J, so that on each revolution
of the driving shaft B through the action of the tappet F, and levers G
and H, the ratchet wheel J, the squeezing roller C, and the gear wheel K
will make a partial revolution, as they are all mounted on the stud L.
This partial rotation will be communicated to the other squeezing
roller D by means of the gear wheel K when and as soon as the gear
wheel M is moved into gear therewith by means of the tappet N pressing
the slide bar P against the lever R, a swell S thereon pressing against
and moving forward the slide W, which carries by means of a stud this
squeezing roller and gear wheel. During this partial rotation of the
squeezing rollers and gear wheels the portion of the wire which is to form
the flattened or working part of a card or cards is formed. The tappets F
and N having passed their greatest "throw" will now admit of the
spring X drawing back the lever R, and the spring Y will draw back
the slide W, gear wheel K, and squeezing roller D, and so there is a
clear and open space between the squeezing rollers, between which the
parts of the wire not to be flattened pass. Z is a spiral spring for
retaining the pawl lever H. in gear with the teeth of the ratchet
wheel J.
If it should be found desirable to give the rolled parts of wire some
sectional form other than that above described it may be done, provided
the requisite length be left unrolled, as above described, to give the
necessary strength and stiffness to the tooth.
Having thus fully described the nature and particulars of this our
said Invention, together with the manner in which the same is to be
performed or carried into effect, we would have it understood that we do
not claim generally, as of our Invention, the construction of the rolling
apparatus above described, but only its use in the manufacture of our
improved cards, that is, for producing wire such as is above described and
shewn in Fig. 5, being suitable for being cut into lengths, and forming
teeth such as are employed by us,

page_text: We also claim the manufacture and use of cards of the improved con-
struction above described, in which are employed teeth formed of wire,
of which the lower parts are left unflattened while the upper or working
parts are flattened or made to present a comparatively acute edge to the
material operated upon.
We also claim as forming a part of our Invention the manufacture
and use of card teeth, such as are above described, in the manner and
for the purpose above mentioned.
In witness whereof, I, the said Thomas Edward Yates, for and on
behalf of myself and the said Henry Yates and William Heaton
Kellett, have hereunto set my hand and seal, this Twenty-
third day of October, in the year of our Lord One thousand eight
hundred and seventy-three.
