An Improved Machine for Bevelling, Grooving, and Channelling
Materials, specially applicable for Use 'in 'Bevelling the Boards
employed for the Covers of Books.
WILLIAM BRIDGEWATER Engineer and Machinist 25 East Bond Street
Leicester do hereby declare the nature of this invention to be as follows:―
This invention relates to the construction of a machine whereby the edges of
boards forming the covers of books are bevelled or by useing a gouge shaped cutter
can be rounded.
This machine consist of a suitable frame in which is mounted a pair of rollers
which may be termed feed rollers to which motion is given by any suitable means.
These rollers are formed of iron wood or rubber or any material suitable to carry
the material to be bevelled or shaped pass 'the cutting edge of the knife or outter
which cutter is placed by the side of the roller at or about the centre of revolution
of said roller.
The knives or cutters are fixed to a stem fitting in a sleeve so that they can be
turned to any angle the bevel requires and also can be brought forward to the
proper place as they are shortened by wear or grinding; such sleeve having also a
stem or upright piece rising out of it and fitting in a hole or sleeve formed on a
bracket attached to or cast on the frame of the machine so that the knife or cutter
can be raised or lowerd to suit the thickness of the material operated upon the
aforesaid arrangment allowing the material to pass under the cutter holders.
A table or platform is placed for the boards or other material to rest on and in
such possition that the bottom roller can rise slightly through the hole cast in the
table for that purpose and sufficient to gripe the material between the two rollers.
The top roller as a suitable arrangment to allow it to rise or fall to suit the
various thickness of 'the material operated upon.
It will be obvious that the aforesaid arrangment of roller and cutting tools may
be used for other purposes than bevelling for book binding such as grooving and
channelling any suitable material.

An Improved Machine for Bevelling, Grooving, and Channelling
Materials, specially applicable for Use in Bevelling the Boards
employed for the Covers of Books.
I WILLIAM BRIDGEWATER of No. 25 East Bond Street Leicester in 'the
County of Leicester Engineer and Machinist 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 the construction of a machine whereby the edges of
D
017

page_text: boards used in the covers of books are bevelled, or by using a hollow or gouge
shaped knife can be rounded as required and also by the use of suitable shaped
knives can be used for many purposes such as cutting vee grooves in card board
for turning up the sides and ends of card board boxes and the like, also for cutting
grooves or channells for holding photo slides and such like purposes.
The improved machine consist of a suitable frame in which is mounted a pair of
rollers to which motion is given by any suitable means these rollers are formed of
iron wood or rubber or any material suitable to carry the boards or other material
past the cutting edge of the knife or cutting tool.
Which knife is fixed in line at about right angles with the shafts of the feed
rollers and in such position that the cutting edge of the knife is placed between
their centres of revolution.
The knife or cutting tool is so arranged that it can be raised or lowered to suit
the different thicknesses of the material used and also to cut the bevel to any angle
required and can also be adjusted inward or outward giving perfect control in fixing
or setting the knife to cut the desired shape.
The cutting edge of the knife being formed at an angle with its length of or
about 45°.
A table or platform is placed for the board or other material to rest upon and as
a raised edge on the table to guide the material straight to the knife.
Also a space is left in the table to allow the bottom roller to rise sufficiently
through to grip the material operated upon.
The top roller as a suitable arrangement to allow it to rise or fall to suit the
various materials operated upon.
In order to enable my invention to be fully understood I describe the machine as
a whole reference being had to the annexed drawings in which
Fig. 1 is a front elivation.
Fig. 2 is an end elivation with the top roller removed to shew the position the
knife E.
Fig. 3 is a vertical section of tool holder and adjusting parts.
Fig. 4 is a plan of tool holder with milled screw L removed and shewing shape
of cutting edge of knife.
Fig. 5 is a section on line a-b Fig. 2 of tool holder.
Fig. 6 is an end view of quadrant Q Figs. 2, 3 & 4 for setting and holding tool
at required angle.
Similar reference letters indicate similar or corrisponding parts throughout the
drawings.
Refering to Figs. 1 and 2 the framing of the machine consist of standards AA
base A & legs B B a table or platform A2 and supported by bracket A³.
Shaft S Fig. 1 & 2 is the driving shaft carring suitable gear at one end and,
feed roller D at the other end.
Shaft S¹ Figs. 1 & 2 carring gear at one end feed roller D' at the other end and
runing through a sleeve c which sleeve is attached to frame by toggle joints d, d, d, d,
and pins iij the toggle joints are connected together at the centre by connecting
rode on which rod is a spring resting against a plate g on standard A the spring is
actuated by hand wheel working on threads cut on connecting rode whereby
preasure is given to the sleeve and thereby to the feed roller D¹ and in a parallel
direction by means of the toggle joints attached to both ends of the sleeve and
therefore giving equal preasure along its length to effectually carry the material
past the cutting edge of the knife
H Figs. 3 & 4 is a sleeve with stem H¹ fitting in F and supported by screw
stud T fixed in stem H and passing through milled headed screw L and held in
position by nuts K, K. It will be obvious that by turning the screw L (which
works in threads cut in the top part of F) to the right or left the sleeve H is raised
or lowered carring with it the peice M to which the knife is screwed thus rising or
lowering the knife or cutting tool the shank or end of M the threaded and fitted

page_text: with nut N by which means the peice M can be brought forward as required to
bring the knife up to it proper place as it becomes shortened by wear or grinding.
The purpose of quadrant Q Fig. 6 and shewn in Figs. 2, 3 & 4 is to hold the
peice M and therefore the knife firm at any angle required by the set screw e¹
passing through slote K¹ of quadrant Fig. 6 and screwing into R on sleeve H the
quadrant being firmly fastened to shank of M by means of set screw V and flate
formed on screwed end of M by removel of part of the thread along one side the
cutting end of knife will often be required to be moved to right or left, which is
accomplished by set screw O & P Figs. 2, 3 & 4 O is threaded into a projection
of F F Fig. 4 and presses against R a piece rising from sleeve H seen in Figs 2, 3
& 4 and set screw P Fig. 4.
By 4 it will be seen that by turning thumb screw O in or out the sleeve can by
the stem be turned in or out and therefore the knife E and when in its right
position can be secured there by set screw P pressing against a flate part u cut
on H' shewn in Fig. 4 & 5.
W Fig. 1 is a small hand wheel with screw working in threads cut in cross
peices W₁ of frame and bos of hand wheel W pressing against sleeve c by turning
hand wheel W sleeve a carring feed roller D' will be or lowered to suit the thick
or thin material as required.
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. Improvement in machinery or apparatus for bevelling the edges of boards
employed in the covers of books and other purposes such as herein discribed and
illustrated consisting essentially of mounting a knife or cutting tool E so that the
cutting edge can be adjusted to any angle or position required, and feed rollers D D¹
to carry the material against the cutting edge of the knife substantially as herein
set forth.
2. The combination of a bevelling machine substantially as herein discribed and
illustrated of knife E and adjustable holder M and quadrant Q and parts H, H¹
adjustable in F of bracket G attached to frame A and feed rollers having an
arrangements whereby they can be seperated to suit the various thicknesses of
material to be operated upon and parts connected therewith and mechanism
substantially as described.
3. The arrangment and combination of parts constituting the complete bevelling
machine the whole operating substantially and for the purpose as heretofore
described.
