We ALFRED RICHARD SADLER, Card Cutter of Duke Street, Macclesfield, JOHN
RUSSELL BEARD, Silk Manufacturer of St. George's Street Mill, Macclesfield and
JOHN GODWIN Designer and Card Cutter of Athey Street Mill, Macclesfield do hereby
declare the nature of our said invention to be as follows:-
This invention relates to new or existing card cutting machinery and consists in an
arrangement of mechanism whereby the machine is rendered capable of being driven by
power instead of treddle mechanism as heretofore.
In performing our invention we elongate the usual lifting lever and connect its
extremity to an eccentric mounted upon a driving shaft working in bearings in the
end or side frame and having one or more speed pulleys for receiving motion by a belt
from a line shaft or other convenient motor. In this manner we obtain the desired
up and down reciprocating motion for the perforating cross bar, or as an alternative
arrangement we dispense with the lifting lever and work the perforating bar direct
by a smaller eccentric mounted on a driving shaft immediately beneath the said cross
bar.
And in order to operate the rack catch we depend from the same a rod, the lower.
extremity of which is connected at the rear to an extension spring which serves to
constantly pull such rod backwards. At front this same extension of the rod is con-
nected to a footlever or treddle by means of a cord or chain passing over a guide
pulley, so that by depressing such treddle the rod is drawn forwards to allow a stud or
arm branching from the lifting lever to come in contact with a projection upon the
depending rod and thus every time the lifting lever oscillates it communicates motion
to the rod and this in turn operates the rack catch. In some cases the treddle is
replaced by a lever arm which is extended back to beneath the driving shaft and in
this case is operated by a cam upon the said shaft working against a bowl or stud upon
the side of the lever arin.

Improvements in or Applicable to Piano Jacquard Card Punching
Machines.
We ALFRED RICHARD SADLER, Card Cutter of Duke Street, Macclesfield, JOHN
RUSSELL BEARD, Silk Manufacturer of St. George's Street Mill. Macclesfield and.
JOHN GODWIN, Designer and Card Cutter of Athey Street Mill, Macclesfield 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
statement:
.
This invention is applicable to new or existing card cutting machinery and consists
in an arrangement of mechanism whereby the machine is rendered capable of being
driven by power instead of or in addition to treddle mechanism as heretofore.
And in order that this our said invention may be the more readily understood and.
carried into practical effect we have hereunto annexed a drawing illustrative of our
improvements and will now proceed to describe the same with the assistance of the
letters of reference marked thereon which indicate similar parts in all the views.

page_text: E
Fig. 1 is a side view and Fig. 2 a back view of a Piano Card Cutting Machine to
which our improvements are applied. In both views a is the table supported upon
the cast iron end frames b and carrying the perforating cross bar c linked to the lifting
lever d. This lifting lever d in accordance with our invention and as applied to
existing machines is extended backwards by the lengthening piece d¹ and connected
at its extremity to an eccentric e mounted upon a driving shaft working in bearings
in the brackets g affixed upon the inner faces of the end frames bas illustrated. The
shaft also carries one or more speed pulleys h for receiving revolving motion from
a line shaft or other convenient motor.
In this manner we obtain the desired up and down reciprocating motion for the
perforating cross-bar c.
And in order to operate the rack-catch i we depend from the same a rod; the lower
extremity of which is connected at the rear to an extension spring which serves to
constantly pull such rod. backwards. At front this same rod is connected to a foot
lever or treddle by means of a cord or chain m passing over a guide pulley n and so
that by depressing such treddle the rod is drawn forwards to allow a stud or arin o
projecting from the side of the lifting lever d to come in contact with a projection p
upon the depending rod j and thus every time the lifting lever d oscillates (whilst the
treddle is so depressed) it communicates motion to the rod j and this in turn operates
the rack catch i.
When the treddle is released the rod j is drawn back by the extension spring k and
in this position the stud or arm o has no effect upon such rod j which consequently
remains stationary.
In the case of machines having cast-iron sides to the frame-work the driving shaft
is mounted in bearings supported upon such sides.
Instead of an eccentric it will be obvious that a crank or its mechanical equivalent
might be substituted for operating the lifting lever.
Although only herein before described and illustrated as applied to existing Piano
Card Cutting Machines it will be apparent that our improvements are equally
applicable to new machines, but in this case we prefer the alternative method of
driving by power indicated in Fig. 3. In this modification we dispense with the
lifting lever and work the perforating bar direct from the driving shaft q which is
situated immediately beneath such bar revolving in brackets affixed to the front
face of the framework. Reciprocating motion is communicated to the perforating
bar by its links being connected to a small eccentric upon the driving shaft and
another eccentric t upon the same shaft serves to impart an oscillating motion to the
forked extremity of a lever i carrying upon its side the stud o for operating the
depending rod of the rack-catch.
On Sheet 2 we illustrate our improvements applied to a Piano Card Cutting
Machine with facilities for operating the same either by power or by the usual treddles.
Fig; 4 is a side view of this improved machine and Figs. 5 and 6 are details of the
same.
In all the views the same letters of reference are used to indicate the parts which
correspond with parts appearing in Figs. 1 and 2 and hence no lengthy description
of this modification will be necessary.
Instead of the foot lever 'l 'the usual treddles A and B are retained connected to
opposite extremities of the see-saw C as illustrated.
The adjustable link D being employed for connecting the rod D¹ of the treddle A
up to the slotted bracket E (see Fig. 6) upon the see-saw when the machine
is being driven by power as illustrated in Fig. 4.
And instead of the extension, spring, cord and pulley for operating the depending
rod (as in Figs. 1 and 2)-the lower extremity of the said rod is formed, as a
ง
segmental slot F and embraces a stud G projecting from the side of the treddle A.
...
The action of this modification will be apparent. By depressing the treddle A. the
slotted extremity of the rod j is drawn forward bringing, the projection into
contact with the stud or arm o upon the oscillating lifting lever d and thus the rack-
catch i is operated.

page_text: A weight H affixed to the treddle B gives a constant tendency to the other
treddle A to rise immediately the foot of the operator is removed and thus the rod j
is forced back to its normal position with its projection out of the reach of the
stud o.
To work this machine by the treddles it is only necessary to disconnect the
adjustable link D and the lengthening piece d' of the lifting lever and to connect the
lifting lever to the upper arm I of the see-saw C by the link J seen in Fig. 5.
By the application of our improvements as aforesaid the operation of card-cutting
is considerably simplified and facilitated more correct cutting is also produced by
reason of the operators attention being less divided and he is enabled to perform more
work in a given time than under the treddle system of working.
'
Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that
what we claim is :-
1st. The improvements in or applicable to Piano, Jacquard Card Cutting Machines
substantially as hereinbefore described.
2nd. The use and application to Piano Jacquard Card Cutting Machines of a
driving shaft and eccentric or its equivalent for operating the lifting lever or perforated
cross-bar by power substantially as and for the purpose hereinbefore described and
illustrated on the accompanying drawing.
3rd. In a Piano Jacquard Card Cutting Machine the employment of a rod
depending from the rack catch and provided with a projection capable of being
drawn forwards so as to engage with a stud or arm upon the lifting lever or its
equivalent and so to operate the rack-catch substantially as hereinbefore described and
illustrated on the accompanying drawing.
