TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARO
LARIVIERE, of Printes. Square, Kennington, in the County of Surry,
Mechanist, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date af
Westminster, the Twenty-eighth day of November, One thousand eight
hundred and twenty-five, in the sixth year of His reign, did, for Himself,
His heirs and successors, give and grant unto me, the said Marc Lariviere,
Tis especial licence that I, the said Marc Lariviere, my exors, adñors,
and assigns, or. such others as I, the said Marc Lariviere, my exors,
adiňors, or 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, my Invention of "CERTAIN
APPARATUS OR MACHINERY TO BE APPLIED TO THE WELL-KNOWN STAMPS, FLY
PRESSES, OR OTHER PRESSES FOR THE PURPOSE OF PERFORATING METAL PLATES, AND
FOR THE APPLICATION OF SUCH PERFORATED METAL PLATES TO VARIOUS USEFUL
PURPOSES;" in which said Letters Patent is contained a proviso, obliging me,
the said Marc Lariviere, by an instrument in writing under my hand and seal,
particularly to describe and ascertain the nature of my said Invention, and
in what manner the same is to be performed, and to cause the same to bo
inrolled in His Majesty's High Court of Chancery within six calendar months
next and immediately after tho date of the said in part recited Letters Patent,

page_text: as in and by the same, relation being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Marc Lariviere do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the Drawings hereunto annexed, and the following
description thereof (that is to say):-
My said apparatus or machinery consists in the application or addition of
certain new and properly constructed parts to the well-known stamps, fly
presses, or other presses used for the perforating of metal plates, and the
particular construction of such stamps or presses need not therefore be
described here, but only such adaptations thereto as I have found necessary to
be made.
Drawing No. 1 is a plan of the parts of a machine for perforating a single
row of holes at a time, taken below the dotted lines * * in Drawing No. 3.
Drawing No. 2, a side section and elevation of a fly press, with the additional
parts fitted to it; and Drawing No. 3, an end view or elevation thereof.
A, A, Fig. 1, in Drawing No. 1, is the frame of a moveable carriage on which
the leaf, leaves, sheet or sheets of metal to be perforated is or are to be placed
in the manner to be described hereafter. It is composed of two square iron
bars A, A, fixed parallel to each other, and of two metal plates one at each
end. Upon these end plates the clamps B, B, B, and B', B', are applied;
B, B, B, are fixed clamps, these are shewn on a larger scale in Fig. 3; each
of them consists of a jaw b, a binding screw c, and two tightening screws d, d,
(as shewn in Fig. 1), which enter cavities made to receive them in the end
plate, their other ends e and f being furnished with jaws and teeth to seize and
hold the leaf or leaves between them. The adjustable clamps B', B', aro
shewn separately on a larger scale in Fig. 4; these have also a jaw b, a binding
scrow c, and two tightening screws d, d', to cach, but they are likewise unite
with a screwed stem g, having a square part upon it, which is guided in the
square staples h, h, Figs. 5 and 6, which are affixed to the under side of the
end plate; and each screwed stem g has a screwed nut or handle i, i, to it,
which acting against the end plate upon being turned draws the jaws B', B¹,
forwards and extends or stretches tight the leaf or leaves of metal held
between them. C, C, &c. are guides, on and between which the carriage A, A,
slides; these guides are each of them affixed on wooden bearers which elevate
the lower sides of the bars of the carriage to the height or level of the base of
the press frame; D, the head of the screw which moves the carriage, it has a
pivot at its other end which turns in a hole made in a block of cast iron let

page_text: into the base of the press; E, a ratchet, wheel, which regulates the motion of
the screw by means of a click &c., which is moved at each stroke of the press;
F, a handle, affixed to the ratchet wheel to move the screw; G, a pair of half
holes affixed to the metal plate, in which the head of the screw is lodged as
will be described hereafter, so that it may be turned freely round but without
moving backwards or forwards; H, HI, the heads of two screws, which servo
to bind or loosen at pleasure the divided or halved female screw J (shewn
separately in Fig. 2), which is affixed by two other screws under the end
plate at the front of the carriage; K, the base of the press; L, L, staples;
with screwed ends and nuts to them which serve to secure the press firmly to
the bench; M, M, the sides of the press frame; N, a bar of wood, covered
with copper, upon which the frame of the carriage or chariot rests when it is
pushed back.
In Drawing No. 2, Fig. 1, A is the fly of the press, having balls or weights
at its ends which are changeable, and must be adjusted according to the forco
required to work the punches; B, the quadruple threaded screw of the press;
C, a safety collar, upon which the shoulder of the screw rests at each stroke of
the press; D, a screw, which adjusts and retains the safety collar at its proper
height; E, the cast iron female screw of the press; F, the collar, which
couples the slide of the press to its screw; G, the slide of the press, to whichi
are affixed the parts which carry the punches by means of the pins and.clamps
to be hereafter described; H, H, the traverse bar of cast iron, which is im-
moveably affixed by screws to the frame of the press, and to which
are also
immoveably affixed by other screws. the cast iron or metal plate I, J, against
which the slide of the press G slides upwards and downwards between guides;
K, the punch carrier, affixed to the slide G by four pins and the clamps L..
Under this piece a bar of steel is affixed which, carries a line of punches?
which must perfectly agree with the matrice M; each punch has a stem to it,
with a head formed upon it which prevents it from falling out of its place
when once secured, as will be described hereafter. L, the clamps, which
secure the punch bearers to the slide; M, the matrice bearer, mounted with
the matrice upon it; this last part requires the greatest perfection of work
manship, in order that the punches may cut the pieces of metal out so clean.
as to leave no burs adhering to the holes in the perforated plates. ». M, Fig. 9,.
the matrice bearer without the matrice up it; the groove in the middle of it
serves to let the pieces, cut out by the punches pass through it into the
drawer P placed beneath the work bench. N, clamps, with screws which
secure the matrice bearer in its place, the disengaging piece, being a steel
plate affixed to the back of the cast-iron plate J, and. bent in such a manner

page_text: as to touch the backs of the line of punches, and prevent the perforated metal
leaf or leaves from rising up or following tho punches. The punches are
made of cylindrical steel wiro, hardened and tempered, and are of different
diameters according to the sizes of the holes to bo perforated by them; and
their lengths must vary proportionally, the thicker ones being of greater
length than the thinner ones. Their heads are spread out by the blows of a
hammer upon cach side of them, as shewn on an enlarged scale in Figs. 10
and 11; or otherwise they may be spread out by the blows of a hammer
upon their tops; and they are lodged within a row of cylindrical holes made
at equal distances apart through the steel punch carrier K to fit them
accurately, and which holes have their tops widened or countersunk, as
shewn in section at Fig. 3 and in the plan Fig. 4. The punches
must all be made of an equal length and their points or lower ends bo
made perfectly flat and cylindrical so as to out or perforate the holes
in the leaves of metal as clean as possible. The matrices must also be made
of steel plates carefully hardened and tempered, and be perforated with as
many circular holes, at equal distances apart, as will correspond with the
number of the punches. Each hole must also be widened below to facilitate the
passage of the pieces cut out through them. The distances of the punches
in the rows depend upon their size and the nature of the metal leaves to be
perforated by them, and the leaves must be moved an equal and similar space
at each stroke of the press by turning the screw, so as to make the holes
equally distant from cach other in all directions. Fig. 5 is a perspective view
of the punch carrier K and the matrico plate beneath it. Fig. 6 is an cnlarged
section of part of the slide G of the press with the punch carrier K affixed to
it, and which is lodged in a rebate or recess made in the bottom of the slide to
receive it. In the upper part of this rebate the punch carrier K is lodged ;
this and other parts will be better scen in the still more enlarged views and
sections, Figs. 12, 13, and 14, at j. The bar of steelj is affixed by four pins
which pass through the holes k, k, k, k, shewn in Fig. 14, and are screwed
into the slide of the press G and by two clamps L, L, with the binding
screws 1, 1, (as shewn in Drawing No. 3); these clamps are shewn on a
larger scale in Figs. 15 and 16. In Fig. 15 the clamp L is shown with its
two sharp edges at top m, m, as holding firmly against the face of the slide G
of the press, it being hung upon the pin n which as aforesaid is serewed into
the slide G and hooked upon the pin o, which is screwed into the bar of steel
j. is the binding screw which screws into the slide G, and its head presses upon
the clamp 1, whilst its ends at and are forced thereby against the slide G

face of the bar j the punch carrier K is firmly affixed by the screws q, q, &c.,
shewn in Fig. 13. r, r, is a row of punches, which are also shewn in part at
r. r, in Fig. 14, fitted into cylindrical holes, widened above; made through the.
punch carrier K, K, as before mentioned, the heads of the punches.being
prevented from rising by the barj as above described. The matrice M is
held fast upon the matrice bearer. M by two clamps N, N,. one of which is
shewn separately at Fig. 17, similar in their action to those shown at L, L,
and having a binding screws to each, which screw into the base of the
frame. One of these clamps N is shewn in Fig. 18 as pressing upon tho
matrice M. Figs. 19 and 20 are intended to give some idea of the nature of
the perforations made in the metal plates by the action of this machine.

References to Drawing No. 4:-The apparatus or machinery hitherto de-
scribed is adapted to perforating holes in metal plates in straight lines or rows;
that which I am now about to describe is intended to perforate circles or parts
of circles or radii of holes in metal plates. In Fig. 1, A is the fly of the press;
B, the quadruple threaded screw; C, the safety collar; D, the collar, which
couples the square slide of the press to its screw; E, the square slide; F, F,
guides of the square slide affixed to the press frame; G, the punch carrier;
this part is shewn separately in Fig. 4, where it is shewn as having a cylin-
drical stem to it, which accurately fits into a cylindrical hole made in the
lower end of the square slide of the press, and is secured by a pin which is
passed through holes made in the stem and slide to receive it. The bottom of
the punch carrier is made flat; and a plate of steel, Fig. 3, is secured to it
by screws, as shown in that Figure. This plate has concentric circles of
cylindrical holes made through it at regular distances apart to receive the
punches, the tops of the holes being widened for the heads of the punches to
lodge in, and which are prevented from rising by resting against the flat bottom
of the upper part of the punch carrier G. The punches are passed through
a disengaging plate D, which is suspended underneath the lower of the guides
F in the following manner :-In Fig. 8, A, A, are two dovetailed slides, which
fit into two dovetailed grooves affixed underneath the lowest of the two guides
of the square of the press F, F, and are prevented from coming out of those
grooves by means of pins passed across through holes made in the ends of the
dovetailed grooves to receive them; B, B, are two metal side plates affixed to
dovetailed slides A, A, and having screws fitted into them which pass through
upright grooves or slits made in two other plates C, C, which are fitted upon
the outsides of the plates B, B, and by which arrangement these outer plates
C, C, can be raised or lowered and secured at any required height by tightening
the screws. To the plates C, C, the disengaging plate D is affixed by other
screws passing through the bottom parts of the plates C, C, into it. Fig. 8 is
a perspective view of these combined parts H; and Fig. 9, a side view, a
profile, or end view, and a plan thereof, cach part being marked with letters of
reference accordingly. The punches also enter corresponding holes made in
matrices to receive them, and which matrices are supported upon the matrice
bearer J of Fig. 1, and as shewn separately at Fig. 2; the matrice bearer
having a hole in it to permit the pieces disengaged by the punches from the
perforated metal plates to fall through into a drawer M placed underneath the
press to receive them. The matrice bearer J is held firmly down in its place

page_text: upon the base of the press by the two clamps K, K, one of which is shewn
Figs. 10 and 11, the former being a

oval hole in the clamp into the base of the press, and the point of the smaller
screw rests in a cavity made in the middle of a flat metal plate shown in
Fig. 10, which rests upon the bench or support of the press. The smaller
screws have circular milled heads upon them, by turning which, when the
other ends of the clamps are placed upon the matrice bearer J, and the larger
screws are screwed into the base of the press, the clamps may be made fast as
required. Instead of perforating entire circles of holes in metal plates at once
by this apparatus, I can also perforate portions or segments of circles only at
a time, and continue the repetition of such portions or segments until the
circles are completed; this I effect in the following manner:-Fig. 5 represents
a set of punches arranged in the form of a segment of a circle in holes made in
a steel plate, which is to be affixed by screws to the lower face of the punch
carrier. This set of punches is to pass through a disengaging plate, supported
in a similar manner to that above described, and be made to enter into cor-
responding holes in matrices. These matrices, however, will require to have
a provision made upon them of two points of steel, the one to receive a hole
upon it, which is previously made in the centre of every metallic plate intended
to be perforated, and as shewn in Fig. 6, in plan at N, and in the side views
Figs. 12 and 13, & another point on one side as at O, upon which one of the
perforations made by the punches is to be placed in order to guide the plate.
accurately to receive the next segment of perforations, and so on until the
circle is completed. Fig. 7 is a segmental disengaging plate; L, L, in Fig. 1,
are two Screws with screwed nuts to secure the press to the bench; Fig. 14
is part of a metallic plate which is supposed to have received one set of eight
segmental perforations which are required to complete the circle; N, the central
hole in it.
Although I have here shewn my said apparatus or machinery as being
applied to fly presses, yet it is equally applicable to stamps or other presses by
suitable modifications, which any competent person may easily make. The
metal plates perforated in the above modes are applicable to the following
amongst many other purposes, namely, to being substituted for the wire gauze
commonly used in safety lamps for miners' lanterns, for gunpowder works, and
stables, strainers or filtres for coffee pots and tea pots, wine strainers or clari-
fyers of liquors in general, calenders and skimmers for kitchen use, fino and
coarse sieves for many purposes, and perforated metal plates for the floors of
malt kilns; and I hereby claim the application thereof to all and every one of

page_text: these purposes.
I do not mean or intend hereby to claim as my Invention
any of the parts described which are already known or in use, but I do hereby
claim the invention and application of those parts of the machines and appa-
ratus to stamps, fly presses or other presses, by which the various effects
described are produced.
In witness whereof, I, the said Marc Lariviere, have hereunto set my
hand and seal, this Twenty-seventh day of May, in the year of our
Lord One thousand eight hundred and twenty-six.
