page_text: LETTERS PATENT to William Hinchcliffe, of Huddersfield, in the County of
York, for the Invention of "IMPROVEMENTS IN CARD SETTING MACHINES."
PROVISIONAL SPECIFICATION left by the said William Hinchcliffe at the
Office of the Commissioners of Patents on the 6th March 1877.

MENTS IN CARD SETTING MACHINES."
My improvements relate,―
"IMPROVE-
Firstly. To the traverse motion or arrangement of mechanism for producing the
lateral motion of the "sheet" or "fillet" during the process of setting. I obtain the
required traverse from the main driving shaft by means of a tappet thereon, which
actuates a catch and ratchet wheel, on the axis of which is also a small pinion.
Above and below this pinion are racks, which are caused to gear alternately with
pinion, being changed or thrown "in" and "out" by cam operated by noggin wheel
on same shaft as pinion and ratchet wheel. This "noggin" wheel also works the
"setting up" motion, and thereby enables me to dispense with separate ratchet
wheel and cam for this purpose.
Secondly. My improvements relate to the wire "feed motion," which consists,
according to my Invention, of a pair of nipping rollers, having intermittent motion
from first shaft by tappet and ratchet wheel and cam. By this arrangement I dis-
pense with the separate holding apparatus now used, besides simplifying the feed
portion.
Thirdly. My improvements consist in a new arrangement of the parts for
forming and inserting the teeth. For this purpose I employ two tubes and one
spindle sliding telescopically within each other, the outer one passing through a
Jong boss mounted on a pivot so as to have a lateral rocking motion of small extent.
The spindle forins the tongue," the tube next to it being the "crown" tube, to
which the crown is attached. The fingers for bending the wire are attached to the
outer tube. When the wire has been fed to the tongue and shaped the tubes are
moved round a quarter of a revolution, the points of the teeth are inserted into the
cloth or fillet, and then the lateral rocking motion takes place, which produces the

page_text: 'knee bend," and the tooth is forced in and the tubes returned to the original
position.
By my Invention the use of a separate mechanism for forming the knee bend is
dispensed with, and I am enabled to use the same machine for both "sheets" and
"filleting." By feeding the wire vertically instead of horizontally the partial revo-
lution of the tubes may be dispensed with.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Hinchcliffe in the Great Seal Patent Office on the 6th Sep-
tember 1877.
WILLIAM HINCHCLIFFE, of Huddersfield, in the County of York. " IMPROVE-
MENTS IN CARD SETTING MACHINES."
My improvements relate,―
Firstly. To a new arrangement of the parts for forming and inserting the teeth,
including the pricking apparatus.
And, Secondly. To the traverse motion or arrangement of mechanism for pro-
ducing the lateral motion of the "sheet" or "fillet" during the process of setting.
In the accompanying Sheets of Drawings, Fig. 1 represents a plan view of a
filleting machine; Fig. 2 is a back elevation of same; and Fig. 3, a cross section
taken through line A, B, of Fig. 1.
The wire is fed in the usual manuer until it is taken hold of by the tongue and
crown, The tongue consists of a spindle C passing through a tube D, to which the
crown E is attached. The tube D passes through a second tube F, and to this tube
the fingers G for bending the wire are attached. The spindle and tubes referred to
are capable of sliding independantly of one another, the whole being carried by the
boss H, which is mounted in centres J, and is free to oscillate vertically when
operated by the cam K, on which it rests. L is the pricking lever, in the end of
which is a slot a, through which passes a pin or screw stud b acting as a fulcrum
or hinge, and allowing of a lateral movement of the lever. The lateral movement
is effected by means of a cam M on the main driving shaft N operating the lever O,
which acts on the pin c on the under side of the lever L. The spring & secures the
movement of the lever in the other direction. The pricker is pushed through the
filleting by the cam P acting on the bent end of the sliding plate Q, in which is a
pine which pushes the pricking lever forward, the spring d producing the reverse
of this motion. The fingers G receive their forward motion from the shaft N by
means of cam R acting on finger S attached to the tube F and their return motion
from the spring T. The tongue C is connected to the outer tube by spring f and
bracket g, and work together. When the points of the teeth have been inserted a
short way into the filleting the boss H lowers, causing the crown and the tongue
to lower also. At the same time the cam U acting on the lever V raises the end v
of the same, causing it to assume a position underneath the tooth, where the knee
bend is required. The crown and tongue carrying down the tooth below the end
of this lever bend the tooth as required, and then resuming their original position
they push the tooth completely into the filleting. It will thus be seen that the
bending of the tooth is effected before the complete insertion instead of afterwards,
as heretofore has been the practice.
Fig. 4 shews the adaptation of my Invention to a sheet setting machine. The
wire is here fed to the tongue and other parts vertically, the said parts being turned
round a quarter of a revolution; or what in Fig. 3 is seen as an elevation may be
taken to represent a plan view of the same when applied to a sheet setting machine.
The sheet is secured vertically instead of horizontally, and the teeth are set with
the crown in a vertical position. The process thus resembles "fillet setting," and
occupies only the same space, thus dispensing with the long machines hitherto used.
The parts shewn bear the same letters as in the other Figures, and do not require

page_text: special reference. The reciprocatory motion of the boss H is obtained from the
cam Y. It will be seen that the motion for producing the knee bend is a lateral
rocking motion instead of a vertical one.
My improvements in the mechanism for producing the lateral motion of the
"sheet" or "fillet" are shewn in Figs. 1 and 2. I obtain this motion from the
main driving shaft N by means of a tappit 2, which actuates a catch 3 and ratchet
wheel 4. On the same axis as the said ratchet wheel is a pinion 5. Above and below
this pinion are racks 6 and 7, which are caused to gear alternately with the pinion 5,
being changed or thrown "in and out" by cam 8 operated by noggin wheel 9
mounted on the same shaft as the pinion and ratchet wheel. The cam 8 is a pen-
tagon or five-sided cam, and moves a tenth part of its circumference, at once pre-
senting a point or angle and flat side alternately to the rack rods above and below
it. The noggin wheel 9 operates this cam through the ten-toothed ratchet wheel 10.
By means of pegs 11 the wheel 9 may cause to work the "setting up motion."
12 are the setting up rollers, the shaft or axis 13 of one of them being elongated
and carrying a wheel 14, which may be either a ratchet wheel or friction wheel;
15 is a catch or lever for working this wheel, and this catch is operated by the
cross bar 16 carried by the rods 17 and 18, the latter of which is forced upwards at
intervals by one of the pegs 11. The extent of the movement may be regulated by
lock screws 19.
Having thus described the nature of my Invention and shewn by Drawings how
the same is to be performed, I would have it understood that I do not confine
myself to the precise details herein shewn and described, neither do I claim the
whole of the parts separately, but what I do claim as my Invention and consider to
be new is,―
Firstly. The telescopic arrangement of the parts for forming the card teeth,
together with the apparatus for operating the same, substantially as herein shewn
and described.
Secondly. The arrangement of apparatus for effecting the traverse of the card
cloth, substantially as berein shewn and described.
Thirdly. The construction and use of mechanisin for forming the "knee bend"
previous to completing the insertion of the tooth, as herein shewn and described, or
any mere modification thereof.
In witness whereof, I, the said William Hinchcliffe, have hereunto set my
hand and seal, this Fifth day of September, in the year of our Lord One
thousand eight hundred and seventy-seven.
