A Machine for Bevelling Cardboard and the like.
.i
I, ROBERT ATCHISON Bookbinder, of 6 Gordon House Road, Gospel Oak
London N.W. do hereby declare the nature of this invention to be as follows:-
It consists of a table having a raised portion along one edge, which raised part
I call the front guide. This guide does not extend the full length of the edge
of the table, there being a part left vacant, preferably, about the centre of its
length.
Over this vacant part, is held a disc cutter, the shaft of which, is carried by a
collar which can be moved through a clamp in the direction of its length.
The clamp which holds the collar, can itself be clamped in divers positions, so
as to set the cutter at any angle to the surface of the table, and is carried by a
suitable frame which can be moved horizontally or vertically to or from the said
edge of the table.
Through the agency of a hand or suitable gearing, rotatory motion is imparted
to the cutter, from a treadle or other source of power.
In order to take up any slackness in the band, an adjustable pulley may be used,
or one pressed against it by a weight or spring.
To bevel a board by hand, it is placed on the table with the edge to be bevelled
against the front guide, it is then pushed forward against the rotating cutter,
which bevels the board in a manner corresponding to the angle at which the disc
is set: in
An automatic device can be used to feed the boards towards the cutter, and is as
follows
A back guide plate can be fixed, at any distance from the edge of the table
before mentioned, and is adjustable by suitable means to be parallel to the front
guide the guides forming as it were a channel between which the boards are moved
forward towards the cutter. Projecting vertically from the back guide, is a piece
forming one side of what I call the box.
Adjustable on the front guide, is a vertical piece, forming the opposite side of
the said box; a portion on the end nearest the cutter is fixed at an angle of 90°,
and projects across the table towards the back guide, an adjustable piece can be
ruised or lowered on this, leaving a greater or less space to allow boards of various
tbicknesses to pass between it and the table.
One or more bands or chains run between the guides, in a groove or grooves in
the table; the bands run over toothed wheels, (the teeth fitting into openings in the
bands), or chains over chain wheels, at each end of the table.
Adjustable at various distances on the bands or chaius, and to project at various
heights above the surface of the table are vertical pieces.
As an alternative the pieces, may be fixed in beight, and the elevation of the
chain or band carrying them be altered. Motion is given to the wheels from the
treadle or other source of power.
The action is as follows Boards are placed in the box against the forward end,
the-adjustable piece on which is fastened so that only one board at a time can pass
underneatli towards the cutter. On starting the power a projecting piece on the
chain or band catches the bottom board, and draws it towards the rotating cutter,
which bevels it fit travels forward; when this board has passed from the box,
the boards above drop by gravity, and the bottom one is caught by the next
....'

page_text: projecting piece, and carried forwards The same cycle of action takes place so
long as the power is applied, or until the boards are all bevelled. A suitable
weight may be placed on the boards to press them down.
To keep the boards flat on the table while they are being bevelled, a disc or
wheel pressed upon them by a spring and adjustably fastened to the back or front
guide or front of the box may be used.
A guard may be placed over part of the cutter,. as a protection to the
workman.
As can be seen, the machine may be fed either by hand or automatically.
If it is desired to cut the bevel down to the under side of the board, a piece of
wood, soft metal, or other suitable substance can be used for the edge of the dise
to cut against.
Bevels can be cut in the centre of boards by arranging the cutter over the table.
On the clamp holding the cutter is a slide, by means of which the disc can be
traversed in its own plane. The disc. is set to the angle. required, the board is
placed beneath, and the rotating cutter is traversed towards and through the board.
The board is then moved in divers directions to secure the desired cut.
A guage can be adjustably fixed to. the table to guide the board against.
For the sake of brevity, throughout the above description of my invention,
I have used the word "board," in speaking of the material operated upon, by the
use of which expression, I mean cardboard or the like.

I, ROBERT ATCHISON, of 6, Gordon House Road, Gospel Oak, London, in the
County of Middlesex, Bookbinder, 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 relates to a machine for cutting and bevelling sheets of cardboard
and the like either on the edges or in the sheet whereby the machine is useful both
for bookbinders for the bevelling of caseboards and the like and for picture
mounters for cutting out picture mounts, which operations may be performed
rapidly, accurately and cheaply.
In the accompanying drawing which illustrates this invention;.
Figures 1 and 2 Sheet No. 1 are broken views in front and side elevation
respectively of the machine adapted for bevelling boards on their edges and
Figure 3 Sheet No. 1 is a view in plan thereof..
Figure 4 Sheet No.1 is a view in side elevation of a modification of this
machine.
Figures 5 and 6 Sheet No. 1 are views in side elevation and front elevation
respectively showing the machine adapted for cutting, and bevelling. holes in, the
boards as for picture mounts and the like.
-
Figures 7 and 8 Sheet No. 2 are views in side elevation and plan respectively
showing an automatic device for feeding the boards past the cutter, and
Figure 9 Sheet No. 2 is a view in transverse section thereof on line a
Figure 8.
Throughout the views similar parts are marked with like letters of reference.
The cutter 4 is fixed to an axle a mounted in a bearing B sp that it is free to
rotate, therein,, and it has fixed on its upper end a pulley. Z whereby rotation may
be imparted to it in any convenient manner.. The bearing B is mounted in a split
Socket C carried by a stem. C' mounted, in a horizontal split socket D. which,
carried by an arm D terminating in a socket E adapted to slide on a bar

page_text: .
projecting from the front of the table 'It will thus be seen that by this metlind
of mounting the bearing carring the axle on which the cutter is mounted the cutter
may be moved in any position within predetermined limits from the stopy on the
edge of the table, and also that it can be set at any angle with the table according
to the bevel required on the edge of the board. The cutter is preferably set to
cut over the edge of the table as shown by Figures 2. and 4, and to this end part-
of the stop y is cut away as shown by the aforesaid figures and the edge of the
table is bevelled, off as shown at v.
..:
To bevel the boards they are pressed forward either by hand, or automatically
from a magazine such as that hereinafter described, against the cutter which may
be either of the bevelled circular knife type as shown or it may take the form of a.
small circular saw....
A guard A may if desired be mounted over the cutter A as shown by Figure 4
to protect the operator.
As a modification instead of mounting the arm D₁ carrying the split socket D on
the bar F it may be fixed direct on to the table as shown by Figure 4.
It will be understood that the split sockets C and D have ears or lugs through
which pass transverse screws as shown whereby they can be contracted and
expanded. The socket E is preferably nipped on to the bar F by means of a set
screw e as shown, but it may be made in the form of a split socket such as C or D
if preferred. As a modification the socket E may be traversed on the bar F by
means of a screw or its equivalent.

When the machine is intended to cut-and bevel picture mounts the split socket C
is formed on. or fixed to a slide C¹ mounted in a saddle D carried by a stem.D
mounted in a split socket E formed on or carried by an arm. F formed on or fixed
to the table Y, the position of the slide C¹ carrying the socket C being varied
with respect to the saddle D in which it slides by means of a suitable screwed adapted
to traverse the slide in the said saddle as shown by Figures 5 and 6: In opération
the cutter A is set at the desired angle and its edge is then traversed down through
the thickness of the board by means of the screw d a suitable piece of soft wcod
such as Y being let into the table for the cutter to cut into. If square holes are
to be cut and bevelled the board is guided up against a suitable adjustable stop y on
the table Y according to the distance the hole or opening is from the edge of the
board, but if circular or other round shaped holes have to be cut and their edge.
bevelled the board is guided by hand. To guide the driving band over the
pulley Z, two guide pulleys Z' are mounted on the frame F in suitable positions.
The automatic device for feeding boards past the cutter consists essentially of a.
magazine or box G formed on or adapted to be attached to the table in any
convenient manner, but preferably constructed in the manner shown by Figures 7, 8
and 9 Sheet No. 2 of the accompanying drawing in which one side of the box is
formed in one with an adjustable stop or guide y¹ adapted to be clamped to the
table Y by means of suitable clamping screws, of an opposite side piece g¹, and of
a front piece 9 formed in one piece and adapted to be clamped to the table by
means of suitable set screws 9³ as shown by Figure 8. In the part g³ is a groove of
in which is mounted an adjustable slide 9 for controlling the opening at the
bottom edge of the side g³ so as to allow but one board to pass out at a time. In
the table Y immediately under the magazine or box G is a groove Y' in which
travels a band or chain H driven and supported by suitable pulleys J, J. On the
travelling band or chain are mounted fingers h which are adapted to engage with
the bottom sheet of board or the like in the magazine and feed it forward to and
past the cutter until it falls away clear of the table. To keep the sheet of board.
down in contact with the table during the time it is being cut a small roller K
mounted on a lever k pivotted to the side g of the magazine G is pressed down in
contact with the sheet of board either by means of a weight L mounted on the
part k' as shown or by any suitable form of spring.
To raise the height of the fingers with respect to the top of the table to suit the
varying thicknesses of board to be cut, I mount in the bottom of the groove Y'a

page_text: false-bottom M for the band or chain H. to rest on. This bottom is guided by
means of a central pin mand is capable of being adjusted vertically with respect to
the bottom of the groove.by means of set screws such as m¹.
The cutter A is driven from any suitable source of power, tension pulleys being
used to keep the driving band or bands taut.
It will be obvious that by using two cutters on one table, the position of one of
which may be varied with respect to the other, the two opposite edges of the board
may be bevelled at the same time.
I wish it to be particularly understood that I do not limit myself to the precise
details of construction hereinbefore described and illustrated by the accompanying
drawing but that I hold myself at liberty, to make, such changes and alterations as
fairly fall within the spirit and scope 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 I
claim is
(1.) A machine for bevelling cardboard and the like, substantially as hereinbefore
described and illustrated by the accompanying drawings..
(2.) A machine for bevelling cardboard and the like having a rotating cutter so
mounted that its, cutting edge can be set at any desired angle with the table for
