PROVISIONAL SPECIFICATION.
Improvements in "Cornering." Machines for Shaping the Corners of
Books and the like.
We, FRED WAITE, of 32, Mount Pisgah, Otley, in the County of York,
Printer's Engineer, and WAITE & SAVILLE, LIMITED, of Falcon Works, Otley,
aforesaid, Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in "cornering" machines for rounding,
mitering, or otherwise shaping the corners of books and the like.
For this purpose we employ a seat or supporting guide for the corner of the
book, or the like, to be operated upon. This seat may be adjustable and supported
upon or let into a suitable table and its sides slope downwards towards each other
at an angle of about 45 degrees with the top of the table and a suitable space is
left between them at the bottom through which the corner to be operated upon
projects. The bolster for supporting the corner of the book is formed or fixed at
one end of the said seat and at the other end a slide fitted in suitable guides is
located which slide is capable of sliding beneath the said seat. This slide carries
the knife or cutter for shaping or forming the corner of the book or the like
projecting beneath the seat. An automatic clamp is provided to slide longitudinally
in the seat a little in advance of the said knife or cutter. This clamp is moved
towards the said bolster, when the knife is moved, under the influence of a weight
or spring but it is arranged to be positively moved in the reverse direction when
the knife is moved backwards. This positive movement may be effected by a
projection on the knife slide engaging the clamp slide or an adjustable piece
thereon. By this arrangement the clamp first fixes the book or its equivalent
against the bolster before the knife reaches it.
The knife slide may be operated by a lever vibrated by a cam on the main shaft.
A clutch controlled by a pedal is preferably introduced between the main shaft and
the driving shaft so arranged that the main shaft is only operated when the pedal
is depressed.
For this purpose the driving wheel on the main shaft may be loosely mounted
upon said shaft and have a ratchet wheel rigidly fixed to it which ratchet wheel
engages a pawl carried by a driving disc fixed upon the main shaft. A slide pin
operated by the said pedal normally engages a projection on this pawl and holds it
clear of the ratchet excepting when it is withdrawn by depressing the pedal.
A spring is provided to return the pin to its normal position when the pressure on
the pedal is removed.
To prevent the main shaft over-running the driving wheel we provide a brake to
the main shaft which may consist of a weighted lever bearing upon the periphery
of a disc on the main shaft. Part of the periphery of the disc may be cut away so
as to relieve the brake as the said pawl is being disengaged from the said ratchet
wheel.

Improvements in "Cornering" Machines for Shaping the Corners of
Books and the like.
We, FRED WAITE, of 32, Mount Pisgah, Otley, in the County of York,
Printer's Engineer, and WAITE & SAVILLE, LIMITED, of Falcon Works, Otley,
aforesaid, Engineers, 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 improvements in "cornering" machines for rounding,
mitering, or otherwise shaping the corners of books and the like.
To fully describe our invention reference is inade to the accompanying sheet of
drawings forming a part of this specification, in which similar letters of reference
indicate corresponding parts in each of the figures.
Figure 1, represents a side view of our improved machine with the driving
wheel (G) of the cam shaft omitted.
Figure 2, represents a plan view of the machine with the table omitted.
Figure 3, is a front view with the table and book seat shown in section on the
broken line a, b Figure 1.
The table A is supported on the side frames A 2 and A 3 connected together by
the lower cross rails A 4 and A5 and the upper cross rails A 6 and A 7.
The seat or corner guide for holding or guiding the corner of the book whilst it
is cut is formed of two fences or guides B and B 2 each fixed at an angle of
45 degrees to the table and at right angles to each other. Beneath these fences
vee guides C, C are provided between which the reciprocating carriage C2 carrying
the cutter C3 is mounted.
The bolster B 3 for supporting the corner of the book is fixed at the front end
of the fences B and B 2 and a bearing piece B4 is fixed at the other end of the
fences to form a guide for the sliding rod D carrying the clamping piece D2
arranged to be brought against the corners of the book immediately before it is cut.
The other end of the rod D slides in the guide D3 fixed to the table A. The
weight D4 is connected by the band D 5, passing over the pulley D 6, .to the
adjustable cross-head D7 fixed by the screw D8 on the rod D and draws
the clamp D 2 forward in advance of the cutter C3 until it bears upon the book
each time the cutter is brought into operation. On the return movement of the
cutter the projection V 4 on the carriage C2 engages the cross-head D7 and draws
the clamp back to the position shown in the drawings. The under side of the
cross-head bears upon the top face of the guides C, C and keeps the rod D from
twisting.
A steel die B 5 the underside of which is the exact shape of the cutting edge of
the cutter C3 is fitted in the bolster B 3 and is fixed by the screw B8. Knives
and dies of different form may be used on the same machine and the fences B
and B2 are made adjustable in relation to each other for the purpose of
adjusting the size of the opening B7 between them which determines the size of
the corner removed.
The carriage C 2 is reciprocated by the lever E the lower end of which is fixed
to the shaft E 2 and its upper end is connected by the rod or coupling piece E3 to
the projection C 6 on the underside of the carriage. To vibrate the lever E an
anti-friction roller E4 is mounted on the stud E5 fixed in the lever E and this
roller engages a grooved cam E 6 fixed on the cam shaft E 7.
The driving shaft F has a pinion F2 fixed on it which drives the toothed
wheel G mounted on the end of the cam shaft E7 in such a way that it is free to
revolve thereon without driving the cam shaft. A ratchet wheel G 2 is formed on

page_text: or fixed to the face of the wheel G and a pawl E8 mounted on the disc E9 rigidly
fixed to the shaft E7 adapted to engage the teeth of the ratchet wheel G2 and
when thus engaged communicates the rotary motion of the wheel G to the shaft E7.
The pawl E8 is normally held disengaged from the ratchet wheel G 2 (as shown
in Figure 1) by means of the sliding pin H and provision is made for releasing the
pawl from this pin when the cutter is required in operation. Figure 4, represents
the pawl and ratchet engaged, with the pin across the path of the pawl in position
to disengage it from the ratchet. For this purpose the pin H is mounted in a
guide hole H 2 in the frame A 3 and its inner end is jointed to the lever H 3 on
the pedal shaft H 4 from which the pedal lever H5 projects to within convenient
reach of the operator's foot. The spring S fixed on the disc E9 pushes the pawl
against the ratchet teeth as soon as it is released by the pin H.
To assist in stopping the shaft E7 after the pawl E 8 is disengaged from the
ratchet the brake lever J, pivoted by one end to the stud J 2 on the frame A 2, is
provided to bear upon the periphery of the brake disc J 5. The disc J 5 is fixed
to the shaft E7 and the spring J 3 stretched between the stud J 4 on the frame
and the other end of the lever J is applied to draw the lever J down on to the
periphery of the disc J 5, with the required pressure.
The periphery of the disc J 5 ss cut away at J 6 in order that the brake may be
off when the pawl is released from the ratchet, as shown in Figure 5 which
represents a separate view of the disc and brake in the relative position they
occupy at the time the pawl is released. The adjustable screw J 8 in the end of
the lever J is provided to bear on the frame A 2 and support the lever when the
cut away portion of the disc is passing the brake.
We find this construction of machine much more convenient in use than the
usual type of machine made with a vertical coruer guide and a vertically moving
cutter carriage.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:
1. The combination in a cornering machine, of the corner seat, the clamp
and cutter carriage arranged and operated substantially as herein shown and
described.
2. In a cornering machine the arrangement of mechanism for throwing the cam
in and out of gear with the driving shaft in combination with an intermittent brake,
substantially as herein shown and described.
3. The improved cornering machine constructed and operating substantially as
herein shown and described and illustrated in the accompanying drawings.
