London, for an Invention of "IMPROVEMENTS IN THE METHOD OF AND
MACHINES FOR PERFORATING CHEQUES, DRAFTS, RECEIPTS, OR OTHER
DOCUMENTS, TO NUMBER OR INDICATE THE VALUE."
PROVISIONAL. SPECIFICATION left by the said Reginald Donkin at the
Office of the Commissioners of Patents on the 20th July 1881.
"IMPROVEMENTS
REGINALD DONKIN, of 14, Tabernacle Walk, Finsbury, London.
IN THE METHOD OF AND MACHINES FOR PERFORATING CHEQUES, DRAFTS,
RECEIPTS, OR OTHER DOCUMENTS, TO NUMBER OR INDICATE THE VALUE."
This Invention of improvements in the method of and machines for perforating
cheques, drafts, receipts, or other documents, to number or indicate the value,
relates, first, to the use of a series of perforating rods or punches arranged together
in a block of rectangular or other form, each moving independently of the other,
but all kept elevated by a plate and spring, and to the use in combination with
this set of punches of other punches so arranged to correspond with certain of the
first named set of punches as to form the device required to be made through a
cheque or other document. For instance, if the block represents 7 rows vertically
of the punches, and 5 transversely, there will be 35 punches; and if the device to
be perforated represents the figure 1, then the acting punches would be the middle
row vertically of the 35 punches, or the 7 punches in the centre vertical row of
the block; these would be acted on by 7 punches set precisely over the others, and
a lever or other device actuating them would press 7 punches of the block through
the paper, and form the figure one. The whole of the 35 punches work into a
bed plate or die perforated to correspond.
The second part of the Invention relates to the mechanism to carry the first
stated principle and method of the Invention into effect.
On the bed plate of the machine I arrange the bed die into which the set of
punches can descend, perforating the paper placed over it by the 35 punches or
other number of the set. Immediately over this is hung the wheel or disc, on the
Ping G71

page_text: edge of which are located the fixed pins according to the device required, which are
to press down the cutting pins or perforators required to correspond with the
device required. In one example of the machine the devices on the edge of the
.wheel are the numerals 1 to 9.. 0 and a star, and the letter L to represent pounds
sterling, though any other devices may be made on the edge of the wheel that can
be made to correspond with such of the 35 pins as will make the device required.
This wheel works in between vertical plates, and slotted or guided at the sides, so
that above a certain point it can rotate; then when vertically over the bed plate,
and the pins of the wheel coincident with the devices required it can descend and
put the perforators into work. The wheel is acted on by a lever fixed through the
wheel, and in the wheel by a ball and socket or other device, one end of the lever
being fulcrumed, the other forming the handle for turning the wheel and for
depressing the pins.
An index is fixed to one end of the lever, or at or near the end, with devices to
correspond with the pins as set, and an index pointer showing when the pins for
the device are immediately over the corresponding pins to form the device.
All the pins of the bed or perforators are arranged in a plate, and kept up above
the bed plate by a spring, so that they are above the bed plate, and allow the
paper to be placed over the bed plate ready for the lever to depress the device
punches, and to force the perforators corresponding thereto through the paper. The
act of depressing the lever actuates a small cam and a foot pressing on the paper,
which, as the lever rises after the perforation, drives or feeds the paper forward
for another adjustment of the devices, and for another perforation at a measured
distance from the former one.
I find the vertical arrangement described perfectly efficient, but it might also be
arranged that the wheel carrying the devices should be horizontal; it will not
however in my opinion be so simple or easy of adjustment.

"IMPROVEMENTS
IN THE METHOD OF AND MACHINES FOR PERFORATING CHEQUES, DRAFTS,
RECEIPTS, OR OTHER DOCUMENTS, TO NUMBER OR INDICATE THE Value."
This Invention of improvements in the method of and machines for perforating
cheques, drafts, receipts, or other documents, to number or indicate the value,
relates, first, to the use of a series of perforating rods or punches arranged together
in a block of rectangular or other form, each moving independently of the other,
but all kept elevated by a plate and spring, and to the use in combination with this
set of punches of other punches so arranged to correspond with certain of the first
named set of punches as to form the device required to be made through a cheque
or other document. For instance, if the block represents 7 rows vertically of the
punches, and 5 transversely, there will be 35 punches; and if the device to be
perforated represents the figure 1, then the acting punches would be the middle
row vertically of the 35 punches, or the 7 punches in the centre vertical row of the
block; these would be acted ou by 7 punches set precisely over the others, and a
lever or other device actuating them would press 7 punches of the block through
the paper,
and form the figure one. The whole of the 35 punches work into a
bed plate or die perforated to correspond.
The second part of the Invention relates to the mechanism to carry the first
stated principle and method of the Invention into effect.
On the bed plate of the machine I arrange the bed die into which the set of
punches can descend, perforating the paper placed over it by the 35 punches or
other number of the set. Immediately over this is hung the wheel or disc, on the
edge of which are located the fixed pins according to the device required, which are
to press down the cutting pins or perforators required to correspond with the
device required. In one example of the machine the devices on the edge of the
wheel are the numerals 1 to 9. . 0 and a star, and the letter L to represent pounds
sterling, through any other devices may be made on the edge of the wheel that can
be inade to correspond with such of the 35 pins as will make the device required.
In cases where the numbering is required to represent dates, it may be preferred
in place of the numeral indicating the month, to use a device of letters, such as Jao.
for January, preceeding the numbers indicating the day of the month; and although
I have only shewn one dise, two, three, or more discs may be placed side by side
to enlarge the range and indication of the perforations required. This wheel
works in between vertical plates, and is slotted or guided at the sides, so that
above a certain point it can rotate, then when vertically over the bed plate, and the
pins of the wheel coincident with the device required, it can descend and put the
perforators into work. The wheel is acted on by a lever fixed through the wheel,
and in the wheel by a ball and socket or other device, one end of the lever being
fulcrumed, the other forming the handle for turning the wheel and for depressing
the pins.
An index is fixed to one end of the lever, or at or near the end, with devices to
correspond with the pins as set, and an index pointer shewing when the pins for
the device are immediately over the corresponding pins to form the device.
All the pins of the bed or perforators are arranged in a plate, and kept up above
the bed plate by a spring, so that they are above the bed plate, and allow the
paper to be placed over the bed plate ready for the lever to depress the device
punches, and to force the perforators corresponding thereto through the paper

page_text: I
The act of depressing the lever actuates a small cam and a foot pressing on the
paper, which, as the lever rises after the perforation, drives or feeds the paper
forward for another adjustment of the devices, and for another perforation at a
measured distance from the former one, but I make no claim to any part of this
feeding device as new, and have not described it in the Drawings.
I find the vertical arrangement described perfectly efficient, but it might also be
arranged that the wheel carrying the devices should be horizontal; it will not
however in my opinion be so simple or easy of adjustment.

In Figure 4 the pins forming the device 4 are shown, and in Figure 1, the
perforations corresponding to the device are shewn ready to be depressed by the
handle to perforate the paper.
Having now described and particularly set forth the nature of the said Invention,
and the means of carrying it into effect, I would have it understood that I claim
as my Invention,―
Firstly. A perforating machine consisting of a series of pins arranged in the
devices required to act upon certain corresponding pins or perforators to pierce the
paper, and so perforate the paper to the device required, in the manuer and for the
purpose substantially as described.
Secondly. The apparatus and mechanism, substantially as set forth in the
Drawings annexed, for the purpose described.
In witness whereof, I, the said Reginald Donkin, have hereunto set my hand
and seal, this Nineteenth day of January, in the year of our Lord One
thousand eight hundred and eighty two.
