COMPLETE SPECIFICATION.
A New or Improved Electrical Apparatus for Perforating
Designs.
I, PIERRE EMILE GLORGET, of 9, Faubourg Poissonniere, Paris, France,
Industrial Designer, 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 has reference to an electrical apparatus for perforating designs
of all kinds on paper cardboard or other suitable material for reproduction of the
designs by using the perforated design as a stencil plate.
My invention is illustrated by the accompanying drawing in which Fig. 1 is a
side elevation of my said apparatus for perforating designs; Fig. 2 is the
corresponding plan; Fig. 3 shews the same apparatus in vertical section and
Fig. 4 represents the same in transverse section.
In all these various figures the same reference letters indicate the same parts.
As will be seen by the drawing, my improved electrical apparatus for perforating
designs is provided with an electro magnet a, a vibrator b, a spindle and needle
carrier c, and a current breaker d, the whole enclosed in a small box which may be
easily held in the hand. The spindle and needle carrier c is threaded on to the end
of the vibrator b by means of an eye formed at the upper end of the needle carrier c
and the latter is held in a vertical position by the two guides e fixed to the front
of the apparatus. The lower end of the needle carrier c is furnished with a cone f
split and screw threaded on the outside on which the screw-ring g presses in such a
way as to grip the needle h, after the latter has been regulated to the required height.
The apparatus stands on a foot i which is flat at the bottom so as to glide over the
design to be reproduced. Two connecting screws j receive flexible wires which
carry the current from a pile 1. The current enters the electro-magnet a by the
connecting screw k the wire m, the block n and the regulating screw p, the spring b',
the platinum o and the wire q. As soon as the current passes through the wire q
the electromagnet a attracts the bar b and the needle carrier c in descending
perforates the design by the needle h. But the bar b in descending carries down
the spring b¹ which being no longer in contact with the screw p breaks the current
so that the needle carrier c rises again under the action of the spring b¹ the contact
of this latter with the screw p takes place afresh, the bar b is once more actuated
and the needle carrier again perforates the design and so on. This alternative
movement is effected very rapidly and produces a series of punctures on the outlines
of the design if the apparatus be moved over the design accordingly.
By means of the current breaker d the apparatus only acts when the button of
this current-breaker is pressed in order to complete the circuit by the contact of
the spindle d' with the angle bracket r which is in contact with the wire j¹ coming
from the connecting screw j from the spindle d' of the current breaker the
current passes into the angle bracket s then into the wire t going to the electro-
magnet.
To stop the apparatus the pressure on the button of the current breaker is
stopped and the spindle of the same recoiling under the action of the spring u the
circuit is broken.
The accompanying drawing illustrates what I consider to be the best manner of
carrying my invention into practice but it will be evident that the shapes, details,

page_text: accessories materials and dimensions of my apparatus may be varied without
departing in any respect from the nature of my invention.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :-
1. In an electrical apparatus for perforating designs the combination of the
electro-magnet a the vibrator b the needle carrier c the needle h and current
breaker d arranged and operating substantially as bereinbefore described and
illustrated by the accompanying drawing.
2. Electrical apparatus for perforating designs constructed and arranged
substantially as hereinbefore described and illustrated by the accompanying
drawing.
