IMPROVEMENTS IN MACHINERY FOR PERFORATING РАРЕВ
Year: 1862

page_text: LETTERS PATENT to Charles Anthony Wheeler, of Swindon, Wilts,
for the Invention of "IMPROVEMENTS IN MACHINERY FOR PERFORATING
РАРЕВ."
Sealed the 17th October 1862, and dated the 12th August 1862..
PROVISIONAL SPECIFICATION left by the said Charles Anthony Wheeler
at the Office of the Commissioners of Patents, with his, Petition, on the
12th August 1862.
I, CHARLES ANTHONY WHEELER, of Swindon, Wilts, do hereby declare tho
naturo of the said Invention for "IMPROVEMENTS IN MACHINERY FOR PERFO
BATING PAPER," to be as follows:-
Disclaiming any Invention of the ordinary serrated disc, the nature of my
Invention consists in the adaptation of the ordinary serrated disc, to a fixed
bed-plate, attached to which bed-plate is a grip for holding the paper securely
down to the bed-plate, while the disc passes over and perforates the paper
in the desired line, to which line the serrated disc is confined by a metal
guide on each side the length of the bed-plate.
The advantages claimed by me are the attaining at comparatively small
cost a machine, that in the hands of a person of ordinary intelligence, will
perform its work with precision, and more than ordinary rapidity, while the

page_text: serrated disc, and the bed plate having so small suface in contact at any one
time the chance of delay is less than where extended surfaces of perforation
and bed are in simultaneous contact.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Anthony Wheeler in the Great Seal Patent Office
on the 10th February 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
ANTHONY WHEELER, of Swindon, in the County of Wilts, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of August, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles. Anthony Wheeler, Her special licence, that J, the said Charles.
Anthony Wheeler, my executors, administrators, and assigns, or such.. others
as I, the said Charles Anthony Wheeler, my executors, administrators, and
assigns, should at any time agree with, and no others from time to time, and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN MACHINERY FOR PERFORATING PAPER," upon the con-
dition (amongst others) that I, the said Charles Anthony Wheeler, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe, and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office,
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Charles Anthony Wheeler, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, that is to say:—
"
This Invention has for its object improvements in machinery for per-
forating paper and the like, and consists of a hand-power perforator, and
relates more particularly to portable or hand perforating machines for the
table, or shop or warehouse counter, as herein described. It is not, however,

page_text: intended to restrict the application of the principle to the portable or hand
form, as the rotary disc perforator and plain flat-surfaced bed plate, which
constitute two of the main features of the said improvements, as well as the
peculiar construction of the gripping and riding frame, which forms a third
feature of the Invention, can be applied in the formation of similar machines
of almost any capacity required, and which larger machines, when fitted with
suitable gearing, may be worked by steam or other power. It is also intended
to apply the same combined principló of construction as regards the rotating
perforator or cutter and gripping and riding and rising guide frame, which
answers the double purpose of holding the paper or other material securely in
the required position for being perforated or cut, while it also acts as a guide
for the rotating perforator for perforating, or partially or wholly severing
paper, cloth, and other fabrics or materials, whether in single sheets, lamina,
or folds.
. Having thus stated the nature and object of my said improvements, I now
proceed to explain the mode of carrying out the same in practice in the
actual construction of the machines, and also to explain their manner of
operation.
EXPLANATION OF THE DRAWING.
Fig. 1 is a side clevation of a portable hand perforating machine; Fig. 2, a
plan of the base frame, the riding or rising frame, and perferator being
removed, and a sheet of paper shewn as placed upon the bed plate for being
perforated; Fig. 3 shews the slotted upright or end of the solo frame next to
the operator; Fig. 4, the opposite end; Fig. 5, a longitudinal section, at the
line. A, B, Figs. 2, 3, and 4; Fig. 6, side elevation of the riding frame and
perforator detached; Fig. 7, plan of the same; Fig. 8 is a transverse section
through the centre of the machine, which also shews the gauge board herein-
after explained. The whole of the Figures are laid down to a geometrical
scale of 6 inches to a foot, and for convenience of reference the same parts of
the machine, which are shewn in various positions in the respective illustra-
tions, are lettered with similar letters, so that the following explanation applies
to each Figure where the letters of reference appear.
REFERENCE.

page_text: as to run upon an accurately turned spindle, the two ends of which are fitted
with handles c, c. The twin strengthening plates screw up to a collar between
them, which collar is left at the base of the male screw, and is turned down
to a thickness a littlo less than that of the perforator or cutter blade; the
latter is bored in the centre so as to fit upon the collar just described. These
twin plates are also formed with external bosses d, d, which are chamfered
down at the edges, as shown at e, e, (Figs. 7 and 8), in order to reduce their
frictional surfaces in contact with the guide flanges presently described. By
preference I form these strengthening plates of brass, gun metal, or any other
amalgam suitable for bearings. ff, two guide flanges, bored in the centre
and mounted upon the spindle which carries the perforator. These guide
flanges may be of iron or other metal, and are held in the required position
by the ferrules 9, 9, at the ends of the handles c, c. These handles are tight-
ened up by the nuts h, h, (Figs. 1, 7, & 8). As these handles are passed
along the guide frame in the direction shewn by the arrows, Figs. I and 7, in
the operation of perforating or cutting, the perferator is upon the centre of
the spindle, while the guide flanges turn only with the handles between the
sides of the bars of the gripping and rising guide frame. j, openings between
the upper and lower bars between which the shaft or impelling handles
traverse; &, two adjusting stops, movable upon the under bars i and i,
fitted with clamping screws 1, 1, for fixing in any required position. The
stop k regulates the backward motion of the cutter and prevents the handles
from passing the line m, the recess formed therein, shewn at n (Fig. 7), being
made of sufficient depth, receives the perforator or cutter and protects its
edgo from contact with the frame. The opposite stop is formed with a
riser or inclined step m', and as the perforator traverses the gripping and
rising guide frame it ascends this rise or step, by which it is instantly lifted
clear off the paper or other material upon the bed plate (placed as shewn at
Fig. 2, and fixed in position by the weight of the guide frame resting thereon-
during the perforating or cutting oporation). The end of the riser or step of
the stop is adjusted nearly to the edge 1, 1, of the paper or other material
upon the bed plate (as shewn at Fig. 2), so that the cutter, having passed
over the full length of the material or the required length of perforation,
rises clear of it and the bed plate upon the riser or step until the shaft passes
into the hollow m² and impinges against the edge of the stop k', when the
momentum of the cutter impels the frame forward and causes it to ascend
bodily upon the inclined bearings o, o, of the riding pieces p, p, in the slotted
ends of the solo franie, the end of the rising guide frame 2 (Fig. 1) is pushed

page_text: up to the line 3 of the upright of the sole fraine q, when, instead of the bearing
surfaces 4, 4, the bearing surfaces 5, 5, rest upon the bottom of the slots 6, 6,
.when the material perforated upon the bed 'plate can be either adjusted for
further perforation or removed from the machine, when other material may be
put into the machine for perforation in succession. The object of making one
of these slots open at the top, as shewn at Fig. 4, is to enable the rising guide
.frame to be separated from the sole frame when required. This is éffected by
-lifting the riding piece p' at the end of the frame. bodily out of the upright,
Fig. 4, when the opposite riding piece p can be drawn through the slot;
shewn at Fig. 3, and the guide frame removed altogether from the sole plate
frame. 7, 7, are two rings of india-rubber, which are placed round the upright
ends of the rising guide frame to act as cushions for counteracting the effect
of the concussion as the frame moves backwards and forwards between the
uprights of the sole frame. The parts of these sole frames 8, 8, are cast
entire or may be made in parts; the fixed bed plate is made of a separate
piece of metal, and is let into a recess in the sole frame, as shewn at Fig. 5.
The upper surface of this cutting bed plate is unperforated and perfectly flat
and even, and stands a little above the surface 10, 10. At the side of this
bed plate two filling pieces of hard wood are fitted, these are shewn at
Fig. 8. Along one or both of these filling pieces a number of divisions,
forming a graduated scale (as shewn at Fig. 2), are cut or otherwise formed;
these divisions or graduations are for the purpose of assisting the operator in
fixing the stops and gauge board in their proper positions. This gauge board
is fitted to or used with the machine, and is intended for fixing the edges of
the paper or other material in a proper position for being operated upon, and
is shewn in section on the left hand of Fig. 8. r is a thin slip of steel or other
metal which passes under the machine and between it and the top of the table
or counter in the space marked r, Fig. 1. One end of this slip is carried up
to form a coil springs which presses against the side of the frame and prevents
the gauge board, to which the slip is attached, from being moved out of its
place. The gauge board is fitted with a fixed stop t and a movable stop t',
the former being placed on one end of the gauge board and the latter across
the same at right angles to the fixed stop. This stop t' is adjustable by two
thumb screws, one of which is shewn in section (Fig. 8), two slots being formed
in the gauge board for the said clamping screw to traverse. The top of this
gauge board w, w, is level with the two edges of the filling piece 11, 11, and a
little below the top of the cutting bed plate. The sole frame, when it is dropped
iuto the opening between the ridge of the frame of the gauge board x and this

page_text: coil spring, holds the. said gauge board i in the required position; but the
latter may be adjusted along the sole frame as required.
Having thus described and ascertained the nature of my said Invention,
and illustrated the manner in which the same may be carried into effect in
practice, I hereby further declare that in performing the said Invention I do
not absolutely restrict myself to the precise forms and dimensions shewn upon
the Drawing, as the same machines are capable of being materially modified,
both in design and in their several details, according as the varying circum-
stances of the case may require.
In witness whereof, I, the said Charles Anthony Wheeler, have hereunto
. set my hand and seal, this Ninth day of February, One thousand eight
hundred and sixty-three.
