CERTAIN IMPROVEMENTS IN THE MANU- FACTURE OF SCISSORS
Year: 1851

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HUBERT
SOMMELET, of Paris, in the Republic of France, Manufacturer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria,
by Her Letters Patent under the Great Seal of the United Kingdom
of Great Britain and Ireland, bearing date at Westminster, the Tenth
day of October, in the fifteenth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said Hubert Sommelet,
my exors, adiñors, and assigns, Her especial licence, full power, sole privi-
lege and authority, that I, the said Hubert Sommelet, my exors, admors,
and assigns, or such others as I, the said Hubert Sommelet, my exors,
admors, and assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick-upon-Tweed, and in the Islands of Guernsey, Jersey,
Alderney, Sark, and Man, and also in Her said Majesty's Colonies and
Plantations abroad, my Invention of "CERTAIN IMPROVEMENTS IN THE MANU-
FACTURE OF SCISSORS;" in which said Letters Patent there is contained a
proviso that I, the said Hubert Sommelet, shall cause a particular description
of the nature of my said Invention, and in what manner the same is to be
performed, by an instrument in writing under my hand and seal, to be in-
rolled in Her said Majesty's High Court of Chancery within six calendar months

page_text: next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Hubert Sommelet, do hereby declare that the nature of my Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following statement thereof, reference
being had to the Drawings hereunto annexed, and to the figures and letters
marked thereon, that is to say:-
My said Invention consists of "certain apparatus for effecting the cutting
out and stamping of scissors," the several parts being cut out of a sheet of steel,
they are afterwards forged and then stamped into the desired shape, after
which they are polished in the ordinary manner.
Figure 1, on Sheet 1 of the Drawings, represents a side elevation partially in
section of the cutting machine; Figure 2 is a corresponding end view of the
same also partially in section; and Figures 3, 4, 5 and 6 are various details.
A, A, A, is a cast-iron frame or standard hollowed in the interior to receive an
eccentric and slide. This frame carries at its upper portion a shaft B, B, on
to one extremity of which is keyed a wheel C, C, receiving its motion from
the pinion D and driving pulleys E, E, the shaft of which carries a fly-wheel
F. The shaft B, B, represented in Figure 4 is fitted with an eccentric I, I,-
which is made in one piece with the shaft; a ring J, J, fits on to the eccentric,
and is in one piece with the short sliding rod K, which receives a perpendicular
movement from the eccentric. The rod K is connected to a slide L,
represented in Figure 5; this slide has at its under side a dovetailed groove
M, in which a die of the shape of the scissors to be manufactured is introduced.
The slide L works in the four grooves N, placed two on each side; these
grooves are represented in Figure 6, and the packing pieces may be tightened
or adjusted by the tightening screws O, O, which press them against the sides
of the slide. The lower die is secured by two clamps P, P, which may be
tightened or loosened by the nuts Q, Q.
The two dies are of the shape of a single blade of a pair of scissors, and
similar to those ordinarily employed for punching or cutting out, and are
therefore not shewn in the Drawings.
The cast-iron frame has an opening R exactly under the die, so that the
articles cut out may fall under the machine in the space S, S.
Figure 1 on Sheet 2 of the Drawing is an end view of the stamping
machine, which somewhat resembles the cutting machine herein-before
described.

page_text: Figure 2 is a corresponding side elevation of the same partially in section,
and Figures 3, 4, 5, and 6 are various details of the machine.
The shaft B, B, which carries the eccentric, instead of working on two
bearings rests on four, the interior bearings being fitted in after the intro-
duction of the shaft; the under ones are tightened by the screws V, V. The
slide is arranged in the same manner as that of the cutting machine, except
that it carrics at its lower extremity a frame T, in which is placed a moveable
die secured by four screws in the centre of each side of the frame; they
are screwed more or less tight according to the size of the die to be held; the
two side screws work in openings X, X, made in the frame, and may be turned
by a key.
In place of the hole R in the bottom of the frame, as described in reference
to the cutting machine, there is a steel block on which is placed the second
die; this die is contained in a box which is drawn away after each piece
is stamped; the box rests against an adjusting piece Z, Z, thereby fixing its
position accurately under the upper die. By this arrangement no clamps
are required to hold the lower die. The two dies have the shape of a
blade of the scissors to be manufactured, cut in intaglis in such a manner
that the two parts stamped form a perfect pair of scissors.
I manufacture the dies with a suitable punch having in relief the hollow
required in the die. This punch is of tempered steel, and to form the
sunk die I merely press it into a block of soft steel; when this block has
received the shape of the punch, it is hardened in this manner; as many
dies as are required of the same kind may be manufactured.
My polishing and filing apparatus consists of a steel grooved roller,
Figure 7, Sheet 1, similar to the rollers used in the manufacture of round-
iron rods, the grooves or flutings being roughened out like circular files; this
small cylinder is placed on the shaft of a lathe; the small circular files are not
all alike, but differ in size and the number of teeth, so that the files with the
large tecth give the required shape to the rings, and with the fine files they
are afterwards polished. They may be polished by a wooden cylinder similar to
the steel one, and which may be placed by the side of the latter.
Having now described and particularly ascertained the nature of my
Invention, and the manner in which the same is or may be used or carried into
effect, I wish it to be understood that I do not confine or restrict myself to the
precise details or arrangements which I have had occasion to describe or refer
to, as it will be evident to the practical man that many alterations may be
made therefrom without deviating from principles or main features of my

page_text: Invention; but what I consider as novel and original, and therefore claim as
the Invention secured to me by the herein-before in part recited Letters
Patent, is,
First, the application and use of the herein-before described cutting
machine, in the manner and for the purpose herein-before described.
Second, the application and use of stamping machines fitted with dies in
the manner and for the purpose herein-before described.
Third, the system or mode of forming the dies, as herein-before described.
Fourth, the application and use of grooved steel rollers with roughened
surfaces, in the manner and for the purpose herein-before described.
Fifth, the application and use of small wooden rollers for more effectually
polishing the interior of the rings of scissors.
In witness whereof, I, the said Hubert Sommelet, have hereunto set
my hand and seal, the Fifth day of April, in the year of our Lord
Tinhteen hundred and for boven
