PROVISIONAL SPECIFICATION.
Improvements in the Traverse Motion of Card Setting Machines.
We WILLIAM WILSON of the Card Factory Liversedge Mirfield in the
County of York Card Manufacturer and WILLIAM MIDDLETON of the same
place Manager do hereby declare the nature of this invention to be as follows:-
The object of this invention is to combine with the operative mechanism of the
screw used for traversing the card setting head in that class of machines commonly
called "endless sheet card setting machines" in such a manner that each "flat"
sheet of card teeth and each space between the "flats are parallel from end to
end, and thus by our new combination to dispense with the necessity of setting flats
or sheets irregular widths and to prevent the necessity of picking the teeth out
which are set by the machine when traversing, while the space is being made
between one flat or sheet to another.
"
"
or
We accomplish our object in the following manner. The spacing cam of the
machine is constructed and operated in the usual manner and in connection with
the ordinary lever in contact therewith I mount an additional lever on a fulcrum
pin the other end of the additional lever being in connection with a sliding bar
provided with two arms projecting in opposite directions which are clear of the
catch box springs so long as the card setting head is inserting teeth in the "flat."
When the required number of rows of card teeth have been inserted to form the
width of a "card flat" the spacing cam operates the first named lever by which
the additional lever is also operated and in such a manner that the arms of the
sliding bar are brought into contact with the respective catch box springs between
the same and a portion of the striking levers by which the rocking motion of the
said levers is reduced, so that the card setting head traversing screw remains
stationary until the card foundation has been moved the required distance to form
a space between the "flats" or sheets when the additional lever and sliding bar are
allowed to resume their normal position and the striking levers to operate the
traversing screw.

COMPLETE SPECIFICATION.
Improvements in the Traverse Motion of Card Setting Machines.
We, WILLIAM WILSON, of the Card Factory, Liversedge, in the County
of York, Card Manufacturer, and WILLIAM MIDDLETON, of the same place,
Manager, 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 :-
The object of this invention is to combine with the operative mechanism of the
screw used for traversing the card setting head in that class of machines commonly
called "endless sheet or screw sheet card setting machines" in such a manner that,
each flat or sheet of card teeth, and each space between the "flats" are parallel
from end to end, and thus by means of our improvement to obviate the setting of
the flats of irregular width, as is the case with machines as at present constructed,
and thereby prevent having to pick the teeth out which are set by the machine in
the space when travelling between one " flat
or sheet to another.
"
In describing the details of our invention reference is made to the accompanying

page_text: “
sheet of drawings, in which Fig. 1. represents a plan of what is known as the
spacing mechanism of a screw sheet card setting machine" with our improvement
added thereto.
Fig. 2. an end view of the same with the driving pullies removed for giving a
clearer illustration of the operating mechanism, and
Figs. 3. 4. and 5. detached details.
The spacing mechanism is placed at the end of the machine as hitherto, and the
spacing cam A. constructed and operated in the usual manner, and in connection
therewith is mounted the ordinary lever B. one end of which is engaged with a
sleeve C. supported by a stud D. in such a manner that, it will slide thereon when
operated by the spacing cam A. through the lever B.
Secured to the sleeve C. is a pin E. against which rests one end of an additional
lever F. the other end being in contact with an arm G. of a sliding bar H. to which
is also connected a spiral spring S. in tension by which the opposite end of lever F.
is kept pressing against pin E.
The sliding bar H. is provided with two arms K. and K¹ which are clear of the
catch springs L. and L' and projections U. of striking levers, so long as the card
setting head is inserting teeth in the "flat."
When the required number of rows of card teeth have been inserted to form the
width of a card flat" the spacing cam A. operates the lever B. thereby causing
the sleeve C. to slide on its support in the direction of arrow, thus allowing the
spring S. to operate the lever F. and sliding bar H. in the direction of arrow Q.
by which the arms K. and K attached to said bar, are brought in contact with
the projections U. U. of striking levers M. and M' thus causing the catch
springs L. and L' to be inoperative and the striking levers M. and M₁ to be clear
of the eccentrics T. and T¹ as shown by detail in Fig. 5. for some portion of their
revolution, thus by these means the pawls N. are prevented reciprocating a
sufficient distance to admit of their engaging with another tooth on the respective
catch wheels P. or P' which are mounted on the traversing screw R. in the
ordinary manner, thus by these means, allowing the latter to remain stationary until
the card foundation has been moved the required distance to form a space between
the "flats" or "sheets," when the spacing cam A. will have arrived at such a
position as to allow the lever F. and sliding bar H. to return to their original
position and the pawls N. on the striking levers to engage with the teeth of the
ratchet wheels P. and P' and thereby to operate the traversing screw R. and
thereby the setting head, across the machine first in one direction and then in the
other, until the card teeth are inserted in the flat to the width required when the
pawls are again prevented operating the traversing screw.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. In a card setting machine the combination of a sliding bar H. with the
projections U. U. of the striking levers M. and M¹ for the purpose as hereinbefore
set forth.
2. The combination of the ratchet wheels P. and P' and traversing screw R
with a sliding bar H. operated at intervals for the purpose as hereinbefore se
forth.
3. The combination of the parts forming the complete mechanism for stopping
the traversing screw R. when required, arranged substantially as and for th
purpose as hereinbefore set forth and illustrated by the accompanying drawings.
