on the 11th August 1874.
I, LOUIS ANTOINE LENÈGRE, of Paris, in the Republic of France,
Bookbinder, do hereby declare the nature of the said Invention for
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR BEVILLING THE EDGES OF CARD-
COARD," to be as follows, that is to say :-

This Invention consists in the construction of an improved machine
for bevilling cardboard both on its outer edge and also on the inner edge
of any countersunk or cut out parts therein.

page_text: The machines hitherto employed for this kind of work have from the
first been very difficult to work, and also clumsy and laborious to use,
but with my improved machine an unskilled workman can in a very
short time work it as well as a person who has worked the machine for a
long time.
The improved machine is constructed of two rectangular frames, a
moveable plate, and a stand or framing united or screwed to a tic picco.
The two frames are hinged together by two sliding hinges, which can be
brought nearer together by means of thrco slides, and arc mounted on
the moveable plate provided with three sliding T picces or squares, which
servo to hold the piece of cardboard to be bevilled.
To fix the cardboard the upper frame is provided with an arbor having
two hooks, which take on to other hooks working in slide boxes held at
one end by two helical springs, the tension of which may be regulated
by a set screw to give the required pressure on the cardboard. The
moveable plate carries a sliding piece, fixed by a set screw, for raising
and lowering the plate according to the bevil required to be given to tho
cardboard. The upper frame has two brass plates, the space between
them forming a dovetail groove in which the plane works. The lower
frame is also provided with a brass plate, over which the plane slides,
the three plates being placed in one line or plane. The plane iron for
cutting the cardboard is removeable, and is fixed and adjusted on the
top plate of the plane by a set screw. The plane iron is varied according
to the bevil to be given to the cardboard.
For cutting bevils in countersunk or cut out parts the plano iron is
triangular, a spring being placed between the two uprights of tho plano
for driving the plane iron into the cardboard. To regulate the stroke of
the plane a suitable stop is provided.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Antoine Lenègre in the Great Scal Patent 30
Offico on the 11th February 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
ANTOINE LENÉGRE, of Paris, in the Republic of France, Bookbinder,
send groeting.

Patent, bearing date the Eleventh day of August, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Louis Antoine Lenégre, Her special licence that
I, the said Louis Antoine Lenégre, my executors, administrators, and
assigns, or such others as I, the said Louis Antoine Lenégre, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for “IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR BEVILLING THE EDGES OF CARDBOARD,” a
communication from Auguste Durr, a person resident at Paris aforesaid,
upon the condition (amongst others) that I, the said Louis Antoine
Lenègre, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Louis Antoine Lenégre, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, referonce being had to the Drawing hereto
annexed, and to the figures and letters marked thereon, that is to
say :-
This Invention consists in the construction of an improved machine
for bevilling cardboard both on its outer edges and also on the inner
edges of any cut out parts thercin.
The machines hitherto employed for this kind of work have from the
first been very difficult to work and also clumsy and laborious to use,
but this improved machine is so simple that an unskilled person can
with a very little practice become acquainted with its action so as to be
able to work it with facility.
The improved machine is constructed of two rectangular frames, a
moveable plate, and a stand or framing.

page_text: And to make the Invention communicated to mo better understood I
will proceed to describe the same by reference to the accompanying
Drawing, in which. Figure 1 is an end elevation of the improved
machine; Figure 2 is a plan of the lower rectangular frame and the
moveable plate; and Figure 3 is a plan of the upper rectangular
frame.
The stand or framing of the machine is constructed of two cast-iron
sido frames M, connected together by a tic-rod U, Figure 1. The loose
rectangular frame B is fixed to the side frames M, and the upper rectan-
gular frame A is hinged to the lower frame B by means of the hinges F.
These hinges have slots, so as to allow of their being adjusted in order
to set the frame A to suit the thickness of the cardboard to be bevilled.
The cardboard is placed between the frames A and B, and. rests on tho
moveable plate C. The moveable plate C is provided with three T pieces.
One of these T pieces I works in a slot a, and may be adjusted as
required to suit the length of the piece of cardboard to be bevilled. The
other two T picces T, T', work in slots b, c, at right angles to the slot a,
and are adjusted to the width of the piece of cardboard to be bevilled.
These T pieces are fixed in position by screw nuts on the under side of
the moveable plate, as shewn in Figure 1.
To fix the cardboard flat on the moveable plato C the frame A is pro-
vided with a shaft D, Figure 3, having a handle D'. This shaft works
in the bearings P, and has a hook N at each end. These hooks take into
other hooks, the stems of which work in the slide boxes G, Figures 1°
and 2. The lower end of the stem of each hook is connected to a helical
spring L, the lower end of each of the springs being fixed to its corre-
sponding side frame M by means of a set screw X, by which its tension
may be regulated so as to give the required pressure on the cardboard.
The moveable plate C moves ou pivots or centres at its upper end, and
is provided with a quadrant IT at its lower end to allow of raising and
lowering the plate according to the bevil required, and is fixed in
position by the set screw K. On the upper frame A, Figure 3, are
mounted two brass plates E¹, E", the space d between thom forming a
dovetail groove which receives and holds the plane or cutting tool shown
in Figures 4, 5, and 6. The frame B has also a brass plate E, Figure 2,
on which the plane slides. This brass plate E is in the same line or
plane as the two brass plates E', E", as shown in Figure 1. The plano
iron or knife which cuts the cardboard is adjustable, and is fixed on the

page_text: plate at the top of the plane by a set screw or otherwise, according to
the bevil.
Figure 4 is a plan, and Figure 5 a side elevation of the plane with its
plane iron or cutter e.
Figure 6 is a plan of the under side of a plane, the iron or cutter ƒ of
which is of the shape required to form a round bevil, whilst if the bevil
is to be slightly flat the iron or cutter is pierced with a hole, in which is
placed a screw with a wing nut, which may be screwed in the slide y,
Figure 4. f, Figure 6, shews the dovetail projection on the under sido
of the plane, which fits in the dovetail groove d formed between the two
brass plates E¹, E", as herein-before described.
Figures 7, 8, 9, 10, and 11 show views of the plane for making bevils
in cut out parts. The cutting iron is triangular, according to the
bevil required, and is held in a dovetail slide. This plane is also
placed on the frame A in the dovetail between the two brass
plates E', E". To cause the tool to pass through the cardboard a
spring is placed between the two uprights A, B, Figure 7, and
which drives the plane iron or cutter into the cardboard.
To form a stop for the plane I fix two pieces O, Figure 12, on
the frame A, each piece being provided with a set screw to regulato
the stroke of the tool in the cardboard. By passing the plane back-
wards and forwards three or four times the cardboard will be penetrated
by the tool, and the bevil will be made.
Having now described the Invention communicated to me, what I
claim as new and intended to be protected is the general arrangement
and construction of an improved machine for bevilling the edges of
cardboard, as herein-before described.
In witness whereof, I, the said Louis Antoine Lenégro, have
hereto set my hand and seal, this Tenth day of February, in
the year of our Lord One thousand eight hundred and seventy-
