Improvements in Perforating Machines.
EMILE KLABER 42 Bengeworth Road Loughboro' Junction London S.E. Gentle-
man do hereby declare the nature of my said invention to be as follows:-
An improved perforating machine, to perforate the figures, or letters on cheques,
documents, or other papers, so as to prevent forgery or alteration.
Heretofore such perforating machines have been most expensive, complicated, &
unreliable in working.
In my invention the handle (there is only one) of the machine, always remains
in the same horizontal position, and facing the user.
It is connected by a rod which holds the cylindrical die plate, the said cylindrical

die plate revolving laterally in a jacket filled thereover.
upon the needles, for the purpose of perforating, and at the foot of the handle and
in front of the cylindrical die jacket, is a dial marked with all the figures, letters,
or signs.
To work the machine the handle which is immovably fixed to the index dial, is
held by the right hand, and turned round so that the figure or sign_required,
(which is marked on the ndex dial) shall be at the top, and the handle is then
pressed down. The cylindrical die plate forcing the needles through the paper,
and so perforating the same, on releasing the pressure on the handle, the paper is
moved a suitable distance forward, (by means of a ratchet wheel) so that the next
figure, or sign, may be perforated.
The machine may be made of a small cast iron bed, which has lugs cast thereon
for holding the lever bed etc. The lever bed is also a cast iron casting made to
hold the needles, the needle springs, ratchet wheel movement, the perforating plate,
and the hollow jacket.
Said hollow jacket is connected to the lever bed by means of a pin, allowing the
said jacket to rock.
At one end of the jacket is the spiral spring, for keeping the jacket raised, and
it its normal position.
The handle rod, to which the cylindrical die plate and index dial is unmovably
fixed, revolve inside the hollow jacket.
The same held by pins or other suitable device within the said jacket.
Full description with drawings will accompany final specification.

Improvements in Perforating Machines.
1, EMILE KLABER, 42 Bengeworth Road, Loughborough Junction, Surrey,
Gentleman (Messrs. Bonn Brothers, United States,) do hereby declare the nature
of this 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 relates to an improved perforating machine, to perforate the figures
or letters on cheques, documents, or other papers, so as to prevent forgery or
alteration.
Heretofore such perforating machines have been most expensive, complicated, and

page_text: This Invention has for its object to simplify, and lessen the cost of, construction of
the machine and render its operation more rapid and reliable particularly as regards
the adjustment of the pattern or die cylinder which determines the form of the letter
or figure to be produced.
With this object, the handle by which the punches are depressed for the purpose
of perforating serves also as the means of rotating the said pattern or die cylinder
and it projects forwards in a nearly horizontal position convenient for being grasped
and rotated, the latter, operation being quickly performed by the fingers of the same
hand as that used for the punching operation, owing to the rotation of the handle
and pattern or die cylinder being about their longitudinal axis for the purpose of
changing the letters or figures to be produced, whereas in other machines the
handle usually radial to the axis of rotation so that it describes a circle about
said axis which involves a shifting of the position of the hand or the use of two
hands to operate it.
In order that the construction and operation of the machine may be more readily
understood, reference must be had to the accompanying drawings forming part of
this specification, wherein figure 1 is a side elevation, and figure 2 a front elevation
of the machine. Figure 3 is a central longitudinal section and figure 4 an underneath
plan of the machine. Figure 5 is a detail section on line 1-1 figure 3.
letters of reference indicate the same parts in all the figures.
The same
A is the bed; B is the perforating table supporting the female die; () is the over-
hanging arm fixed on the bed A; D are the perforating punches mounted in the
free end of the arm C; E is a rock lever oscillating on centres e mounted in lugs
on the arm or lever bed C; F is a jacket formed on the lever and enclosing the
polygonal die or pattern cylinder G which is carried by a spindle H mounted in a
longitudinal socket in the lever E retained therein by a pin h engaging in a
neck in the spindle, said spindle having affixed to its projecting front end the
handle I. The front of the jacket F is closed by an index dial plate J fixed to the
spindle H so that the handle, spindle, dial plate, and pattern cylinder, all revolve
together about their longitudinal axis for the purpose of bringing the dies of the
pattern cylinder into operative position as required, the dial plate facing the user
and having a circle of characters corresponding to those which the pattern cylinder
is adapted to produce, so arranged in relation thereto as to denote, by reference to
a fixed index on the top of the jacket, which of the dies of the pattern cylinder is
for the time being in the lowermost or operative position. The various faces of the
pattern cylinder are drilled out leaving the face intact only at those places corre-
sponding to those of the punches which are to be brought into operation for the
purpose of perforating the character desired and the lower side of the casing F has
an aperture to admit of the pattern cylinder being pressed down upon the punches.
Upon the front end of the pattern cylinder is a circle of notches K for engagement
with a bevelled pin k standing up from the top of the punch-holder, in order to
ensure the accurate register of the die of the pattern cylinder with the punches. A
spring pressed pin L mounted in the rock lever E projects into jacket F and bears
against the rear end of the pattern cylinder which has shallow notches corresponding
to the various die faces of the cylinder, into which notches the rounded end of the
pin falls, so as to facilitate determining the accurate adjustment of the dial and
pattern-cylinder with regard to the index and punches without materially impeding
their rotation. The punches D are fitted to slide independently in guides in a case c
carried by the arm C the punches being regularly arranged in rows and passing
through holes drilled in the bottom of said case, the guides for the punches being
preferably formed by a block M of soft metal or alloy run in the casing c around
the punches after the latter are in place. The punches have collars & formed on them
near their upper ends which are held between a fixed upper plate N and a movable
lower plate both perforated with holes through which the punches pass, a spiral,
spring P pressing the plate O upwards and so raising the punches when not acted
on by the die cylinder. The feed mechanism, by which the paper is propelled
onwards a suitable distance after each depression of the punches, consists of a pair of

page_text: feed wheels Q carried by a shaft 9 mounted within the hollow bed A, the wheels
projecting upwards through apertures in the perforating table B so that the paper is
nipped between them and a corresponding upper pair of pressure wheels Q¹ mounted
to turn idly on an axis carried by the casing c. The shaft is mounted at the
front end in a bearing in a lever r pivoted at r, and whose tail end is acted on by
the tail end of a finger key or lever R rocking on an axis R¹, the key proper pro-
jecting at the front of the bed A in position to be readily depressed by the hand
of the operator for the purpose of depressing the feed wheels Q in order to introduce
the document between the pairs of pressure and feed wheels and place it beneath the
punches in position to be perforated thereby. A spring (not shown) under the tail
end of the lever presses the feed wheels upwards against the pressure wheels with
the necessary force to grip the paper. The other end of shaft is journaled in a
fixed bearing and said shaft is rotated at each oscillation of lever E to the extent of
one tooth of a ratchet wheels upon said shaft, by a propelment comprising a pawl t
thrown by a spring t¹ into engagement with ratchet wheels and pivoted at to a
bracket T rigidly fixed to a rod U coupled at u to the tail end of lever E and sliding
through a guide in the arm C. A spiral spring V upon this rod confined between
said guide and the bracket T raises the front end of the lever E carrying the die
cylinder and handle to the normal position shewn, after each perforating operation.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is;
1. The herein-described perforating machine wherein the handle by which the die-
cylinder is depressed and rotated revolves about its longitudinal axis for the purpose
of adjusting the die cylinder with regard to the punches and is arranged in a for-
wardly-projecting position substantially in alignment with the axis of said cylinder
and with the rock lever by which it is carried as specified.
2. In the herein described machine, the combination, with the rock lever, of the
die cylinder, its spindle, handle, and index dial plate, mounted to revolve about
their longitudinal axis in said lever and to oscillate therewith, as specified.
3. In the herein described perforating machine, the combination, with the
vertically-movable punches, of the rock lever mounted to oscillate on a horizontal
axis, the die cylinder having its operative surfaces fashioned on its periphery and
mounted to rotate upon an axis carried by the lever, and a handle on the cylinder
axis forming a prolongation of the rock lever, whereby the cylinder is rotated and
the rock lever oscillated for the purpose of depressing the cylinder and punches,
substantially as specified.
