Improvements in Apparatus for the Manufacture of Stencil Plates
Serving as Patterns for Garments and the like.
-:
I, HENRI RAYNAL, of Rue Gambetta, Lille, in the Republic of France,
Mechanician, do hereby declare the nature of this invention to be as follows:-
This invention relates to a milled cutter intended for the production of per-
forated plates for stencilling patterns for dresses, under-garments boot and shoe
uppers and the like.
This milled cutter consists in principle of a series of punches arranged circularly
the cutting edges of which are separated by intervals corresponding to the full
portions of the stencil plate.
One form of milled cutter consists of three dises; two of which are practically
similar, and between these is arranged a central disc.
The outer dises are provided upon their periphery with a series of cuting teeth
the cutting edge of which is directed perpendicularly to the axis of the disc.
The central disc is also provided with cutting teeth, but the cutting edge of these
is parallel with the axis of the disc.
These teeth are separated one from the other alternately by the length of a
tooth and by the length of the interval separating two consecutive teeth.
The three discs are mounted upon an axis common to them all, and tightened
between a collar upon the said axis and a nut, in such a manner that the teeth
of the outer dises are opposite one to the other and that the teeth of the central
disc are arranged at the extremities of the teeth of the outer dises. The cutting
edges of the central discs being at right angles to the cutting edges of the outer
discs, a series of rectangular punches is obtained, each of which is of the length
of the teeth of the said outer discs and of the width of the teeth of the inner
disc. Springs fixed upon the periphery of the central disc between the teeth
which are separated by the greatest interval, serve to force out of the punches,
the pieces of paper cut out by these latter.
This arrangement of a milled cutter consisting of several dismountable discs
presents the important advantage of enabling the cutting edges to be set when
the punches become blunted; for this purpose it is only necessary to dismount
the discs and sharpen the cutting edges separately.

page_text: It should, however, he understood that I do not limit myself to the arrange-
ment which has just been described, and that I reserve the right to form my
cutters in a single piece or to arrange them in any other suitable manner.
Thus
for example I may equally well adopt the construction in which a milled cutter
is constituted by a hub having the form of two truncated cones united at their
smaller base. Around this hub radiate punches of the ordinary kind which
are fixed alternately upon the periphery of first one and then the other of the
truncated cones of which the hub consists. The said punches are inclined in such
a manner that the centres of their cutting portions are all situated in the same
plane. This alternate arrangement of the punches enables the interval separating
their cutting portions to be reduced by one half, and consequently enables perfora-
tions to be formed in the plates which are sufficiently near one to the other,
contrary to what would be the case were all the punches mounted side by
side upon the same cylinder.
Whatever the constructional form adopted, the cutter may be mounted in a
fork provided with a handle or upon the shaft of a suitable machine, to which
shaft a movement of rotation is imparted.
In order to form a perforated plate by means of a cutter mounted upon a
handle, the cut lines of the pattern which it is desired to form are first of all
traced upon paper or tissue of any suitable kind; this paper or tissue is then
placed upon a table of hard wood or upon a sheet of soft metal and the cut lines
of the pattern are followed with the cutter whilst exerting a slight pressure with
the hand. There is thus obtained, by the use of a cutter of the first type, a
plate having elongated rectangular perforations. These elongated perforations
present the advantage of enabling the cloth upon which the pattern is to be
traced to be reached by means of a pad charged with colouring matter, when the
plates are used for making patterns for costumes.
As above specified, the perforation of the plate may equally well be effected by
machinery. For this purpose the cutter may be mounted upon the extremity
of a shaft which is capable of rotation in a frame. The shaft communicates the
rotation, which is imparted to it in any convenient manner, by means of gear-
wheels to another parallel lower shaft which carries at its extremity opposite the
cutter a roller. At the place at which the lower shaft traverses the rear portion
of the frame, it is made olive shaped and its bearing is guided in a fork of the
frame, in such a manner as to be capable of vertical displacement with respect to
this latter, by means of a pedal and a system of levers. In order to perforate a
plate which has been previously outlined, it is passed between the cutter and the
roller which are normally separated; the pedal is then acted upon in such a
manner as to raise the roller and by its means to slightly press the plate against
the cutter. Any other suitable arrangement may however be employed.

Improvements in Apparatus for the Manufacture of Stencil Plates
Serving as Patterns for Garments and the like.
I. HENRI RAYNAL, of Rue Gambetta, Lille, in the Republic of France,
Mechanician, do hereby declare the nature of this invention and in what manner

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to a milled cutter intended for the production of per-
forated plates for stencilling patterns for dresses, under-garments, boot and shoe
uppers and the like..
This milled cutter consists in principle of a series of punches arranged circularly
the cutting edges of which are separated by intervals corresponding to the full
portions of the stencil plate.
In order that my invention may be readily and clearly understood and also the
means for carrying it into practice, I have represented in the accompanying
drawing, two forms of milled cutters constructed in accordance with
invention.
The first type which is the one I prefer, is represented in Figures 1 to 3.
Figures 1, 1 and 2 represent in front and side elevation each of the constituent
parts of the milled cutter in detail, and Figure 3 shews the cutter mounted in a
handle.
The second type of construction is represented in front elevation and in cross
section in Figures 4 and 5.
Figure 6 represents a portion of a perforated plate, shewing the nature of the
lines of perforations.
Figures 7 and 8 illustrate the application of a cutter of this kind to a machine
adapted for the purpose in view, in longitudinal elevation and end elevation.
The milled cutter represented in Figure 1 to 3 consists of three dises; two of
which A (Figure 1) and A (Figure 1) are practically similar, and between these
is arranged the third or central disc B (Figure 2).
The outer dises A A are provided upon their periphery with a series of
cutting teeth a ², the cutting edge of which is directed perpendicularly to the
axis of the disc.
The central dise B is also provided with cutting teeth b, but the cutting edge
of these is parallel with the axis of the disc.
These teeth are separated one from the other alternately by the length of a
tooth and by the length of the interval separating two consecutive teeth a
OF a¹
The three discs are mounted upon an axis C Figure 3 common to them all and
held tightly together between a collar c upon the said axis and a nut c', in such a
manner that the teeth of the discs A A¹ are opposite one to the other and that the
teeth of the central disc B are arranged at the extremities of the teeth a¹ of
the outer discs A A. The cutting edges of the central disc & being at right angles
to the cutting edges of the outer discs a and, a series of rectangular punches
is obtained, each of which is of the length of the teeth of the said outer
dises and of the width of the teeth of the inner disc. Springs fixed upon
the periphery of the central disc B between the teeth which are separated
by the greatest interval, serve to force out of the punches, the pieces of paper or
cardboard cut out by these latter.
This arrangement of a milled cutter consisting of several dismountable discs
presents the important advantage of enabling the cutting edges to be set when
the punches become blunted; for this purpose it is only necessary to dismount the
discs and sharpen the cutting edges separately. It should, however, be understood
that I do not limit myself to the arrangement which has just been described, and
that I reserve the right to form my cutters in a single piece or to arrange them
in any other suitable manner. Thus for example I may equally well adopt the
construction represented in Figures 4 and 5, in which the milled cutter is con-
stituted by a hub 1) having the form of two truncated cones united at their smaller
base. Around this hub radiate punches d of the ordinary kind which are fixed
alternately upon the periphery of first one and then the other of the truncated
cones of which the hub consists. The said punches are inclined in such a manner
that the centres of their cutting portions are all situated in the same plane. This

page_text: alternate arrangement of the punches enables the interval separating their cutting
- portions to be reduced by one half, and consequently enables perforations to be
formed in the plates which are sufficiently near one to the other, contrary to what
would be the case were all the punches mounted side by side upon the same
cylinder.
Whatever the constructional form adopted, the cutter may be mounted in a
fork provided with a handle E (Figure 3) or upon the shaft of a suitable machine,
to which shaft movement of rotation is imparted (see Figures 7 and 8).
In order to form a perforated plate by means of a cutter mounted upon a handle,
the outlines of the pattern which it is desired to form are first of all traces
upon paper or tissue of any suitable kind; this paper or tissue is then placed
upon a table of hard wood or upon a sheet of soft metal and the outlines of the
pattern are followed with the cutter whilst exerting a slight pressure with the
hand. There is thus obtained, by the use of a cutter of the first type, a plate
having elongated rectangular perforations see Figure 6.
These elongated per-
forations présent the advantage of enabling the cloth upon which the pattern is
to be traced to be reached by means of a pad charged with colouring matter,
when the plates are used for making patterns for costumes.
As above specified, the perforations of the plate may equally well be effected
by machinery for this purpose the cutter may be mounted upon the extremity of
a shaft f Figure 7 which is capable of rotation in a frame F. The shaft f com-
municates the rotation, which is imparted to it in any convenient manner, by
means of gear-wheels to another parallel shaft fl which carries at its
extremity opposite the cutter M a roller G. At the place at which the shaft f
traverses the rear portion of the frame (at 2) it is made olive-shaped and its
bearing is guided in a fork ft of the frame, in such a manner as to be capable
of vertical displacement with respect to this latter, by means of a pedal P and a
system of levers (Figure 8). In order to perforate a plate which has been
previously outlined, it is passed between the cutter M and the roller G which are
normally separated; the pedal P is then acted upon in such a manner as to raise
the roller G and by its means to slightly press the plate against the cutter M.
Any other suitable arrangement may however be employed.
I wish it to be understood that I am aware that disc-shaped cutters having
punches arranged around their peripheries have been previously used for per-
forating paper and other material and I make no general claim to the use of such
cutters.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A milled cutter intended for the formation of perforated plates for stencilling
the patterns of costumes and so forth, the said cutter being constituted essentially
by multiple punches arranged circularly around the axis of the cutter.
2. As a practical method of realising the object of Claim 1, a cutter composed
of three adjacent dises having cutting teeth, the teeth of the central disc being
arranged at the extremities of the teeth of the lateral discs and at right angles
to these latter, the central disc being provided in addition with springs for freeing
the cutter from the pieces cut out in such a manner as to constitute punches of
elongated form which may be readily dismounted, substantially in the manner
described and for the purpose specified with reference to Figures 1 to 3 of the
accompanying drawing.
3. As a practical method of realising the object of Claim 1, a milled cutter
The hub of which is composed of two truncated cones united at their smaller base
and inclined punches of the ordinary kind, fixed alternately upon first one and
then the other of the truncated cones, substantially in the manner described and
for the purpose specified with reference to Figures 4 and 5 of the accompanying
drawing:

page_text: 4. The application of milled cutters provided with multiple circular punches
as claimed above to a machine comprising two rotating shafis one of which
rotates in fixed bearings and carries the cutter and the other oscillating and
carrying a roller opposite to the cutter, substantially as described with reference
to Figures 7 and 8 of the accompanying drawing.
