IMPROVEMENT IN CARD SETTING MACHINES
Year: 1876

page_text: LETTERS PATENT to Henry Yates and Thomas Edward Yates, of Cleckheaton,
in the County of York, Card Makers, and Henry Bedford, of the same
Place, Foreman Mechanic, for the Invention of "IMPROVEMENT IN CARD
SETTING MACHINES."
PROVISIONAL SPECIFICATION left by the said Henry Yates, Thomas Edward
Yates, and Henry Bedford at the Office of the Commissioners of Patents on
the 14th June 1876.
HENRY YATES and THOMAS EDWARD YATES, of Cleckheaton, in the County of
York, Card Makers, and HENRY BEDFORD, of the same Place, Foreman Mechanic.
"IMPROVEMENT IN CARD SETTING MACHINES."
This Invention consists of an improved combination of mechanism for operating
or working the "pricker," whereby the "incline" used in connection with the
latter is dispensed with, and a higher speed can be attained.
According to this our Invention, in lieu of working the pricker obliquely, we
impart a vertical motion for placing the pricker in position for piercing the
material in which the " teeth are to be set, and for removing or clearing the
same during the operation of setting.
ガラ
By means of a tappet and connecting arms and rocking shaft a rising and falling
motion is given to a slide block, upon which block a
"Swell or projection con-
nected with the pricker rests, so that as the block rises and falls the pricker is
first placed in position for piercing the material, and is then lowered out of the
way that the tooth or card may be inserted.
There is in the vertical motion just described a much shorter traverse of the
pricker (than when as heretofore the oblique motion was used), whereby a higher
speed of working can be attained, and with better result, because the pricker was
apt to "jump" or vibrate on the incline, and did not always pierce the material at
the exact place or point necessary.

IMPROVEMENT IN CARD SETTING MACHINES."
This Invention consists of an improved combination of mechanism for operating
or working the "pricker," whereby the "incline" used in connection with the
latter is dispensed with, and a higher speed can be attained.
According to this our Invention, in lieu of working the pricker obliquely, we
impart a vertical motion for placing the pricker in position for piercing the
material in which the "teeth" are to be set, and for removing or clearing the same
during the operation of setting:
By means of a tappet and connecting arms and rocking shaft a rising and falling
motion is given to a slide block, upon which block a
"swell " or projection con-
nected with the pricker rests, so that as the block rises and falls the pricker is first
placed in position for piercing the material, and is then lowered out of the way that
the tooth or card may be inserted.
There is in the vertical motion just described a much shorter traverse of the
pricker (than when as heretofore the oblique motion was used), whereby a higher
speed of working can be attained, and with better result, because the pricker was
apt to "jump" or vibrate on the incline, and did not always pierce the material at
the exact place or point necessary.
Such being the nature and object of this our said Invention we will now proceed
to describe the same in detail, and 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 several views or Figures.
Figure 1 is a side elevation of part of the machine having our improvements
attached; Figure 2 is a plan view of Figure 1; Figure 3 is a front elevation of the
slide pieces.
"
At A is a tappet (on the tappet shaft B) which operates the connecting arm C,
and by the latter gives to the shaft D a partial "to-and-fro" rotation or a rocking
motion. The finger piece E attached to the shaft D imparts to the slide block
Fa rising and falling motion, so raising and lowering the "saddle or piece G on
which the heel or projecting part d of the pricker H rests, whereby the latter is
raised into position for piercing the leather or material in which the card "teeth"
are to be "Bet or received, and on the pricker being withdrawn the saddle piece G
and pricker H are by the action of the cam A and finger E lowered vertically; this
motion of the pricker being shorter than the old or oblique, traverse, the pricker
is more speedily out of the way of the advancing "finger and tongue," which
inserts the card teeth. L is a spring for holding the arm C to the tappet A.
"
By imparting to the pricker a vertical motion, that is to say, by working the
pricker directly upwards and downwards (as distinguished from an oblique sliding
motion) not only is a higher working speed of the machine attained, but the
tendency of the pricker to " jump" or vibrate, and so pierce the material at other
than the exact point requisite is obviated. There is a greater production and less
waste by "marling" of the teeth, and less "filling-in" or hand work in finishing
the card.
The pricker H is advanced for piercing, and withdrawn and receded by the
vibrating arm M, this being the old and well understood means for such purpose.
Having thus fully described the nature and particulars of this our said Invention,

page_text: together with the manner in which the same is to be performed or carried into
practical effect, we would have it understood we claim, the use of the finger E
and slide F, or the equivalents of the finger E and slide F, for imparting a vertical
or direct raising and lowering motion of the pricker H in the manner and for the
purpose herein described.
In witness whereof, we, the said Edward Thomas Yates, Henry Yates, and
Henry Bedford, have hereunto set our hands and seals, this Eleventh day of
December, One thousand eight hundred and seventy-six.
