or
My invention relates to apparatus for facilitating the cutting of glass into pieces
of predetermined size and shape and is designed more particularly to provide
apparatus for cutting "quarries or diamond shaped pieces, squares "lines"
other similar geometrical forms for lead glazing, and for like purposes where a large
number of pieces of glass of similar shape and size have to be cut.
As hitherto carried out the range of glass from which the pieces are to be cut is
laid upon a board and after being cut by the diamond is lifted up to enable the
piece to be detached from the range. This takes up a considerable amount of time
and an important feature of my present invention is the provision of means, whereby
the pieces of glass may be severed from the range from which they are cut without
the necessity for lifting the latter.
A further important feature of my said invention is the provision of suitable
guides and stops for ensuring the cutting of the glass to the correct form and size.
Another feature of my said invention is the provision of an adjustable stop-piece
for preventing the diamond being accidentally forced or slipped over the sharp
edge of the glass before the cut is made, whereby the risk of damage to the glass of
the diamond being pulled out of its setting is to a great extent avoided.
In carrying my said invention into practice I construct a board or table capable
of being mounted on suitable supports or trestles and having an aperture therein
over which the glass to be cut projects, and through which the pieces fall as they
are severed. An arm or rod formed of two parallel pieces or strips one above the
other, projects across this aperture being attached at one extremity to a stud or
centre-pin while the other end thereof moves in a segmental-guide formed of metal
or other suitable material graduated, if desired, to indicate the angle to which the
bar is adjusted. The aforesaid stud or centre pin and the extremity of the bar
which moves in the guide are each provided with suitable clamping nuts or set-
screws for fixing the arm in any desired position. The lower of the two strips of
which this arm is composed is preferably formed of steel in order to secure greater
rigidity, a space being left between the two strips sufficiently wide to admit of the
insertion of the glass, the upper strip acting as a guide for the cutting-tool and
being provided with a sliding-piece which can be moved along it to any required
position to act as a stop to prevent the diamond before the cut is made slipping
over the sharp edge of the glass.
A stop-piece the position of which can be readily adjusted is provided in
combination with the arm so that if the glass is pushed up against this stop-piece
before each cut, the sizes of the pieces of glass will be constant. This stop-piece
consists of a short arm or projection capable of revolving or swivelling upon a
centre-pin or stud which moves in a slot or guide, so that the position of the said
stop can be adjusted to the size of glass to be cut. An arm or link is preferably
connected to the extremity of the stop so that greater rigidity can be secured, this
arm or link being fixed by means of a pin or screw passing through a slot therein
and having a winged nut provided thereon for clamping the same securely. A
similar nut is also provided on the aforesaid centre-pin or stud which carries the
adjustable stop.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Facilitating the Cutting of Glass
into Pieces of Predetermined Size and Shape.
I, EDWARD REYNOLDS, of 5 Torriano Cottages, Camden Road, in the County
of Middlesex, Manager, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to apparatus for facilitating the cutting of glass into pieces
of predetermined size and shape and is designed more particularly to provide
apparatus for cutting "quarries or diamond shaped pieces, squares,
"lines or
other similar geometrical forms for lead glazing, and for like purposes where a
large number of pieces of glass of similar shape and size have to be cut.
As hitherto carried out the range of glass from which the pieces are to be cut is
laid upon a board and after being cut by the diamond is lifted up to enable the
piece to be detached from the range.
This takes up a considerable amount of time and an important feature of my
present invention is the provision of means, whereby the pieces of glass may be
severed from the range from which they are cut without the necessity for lifting
the latter.
A further important feature of my said invention is the provision of suitable
guides and stops for ensuring the cutting of the glass to the correct form and size.
Another feature of iny said invention is the provision of an adjustable stop-piece
for preventing the diamond being accidentally forced or slipped over the sharp edge
of the glass before the cut is made, whereby the risk of damage to the glass of the
diamond being pulled out of its setting is to a great extent avoided.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings in which
Figure 1 is a plan of an apparatus for facilitating the cutting of glass into pieces
of predetermined size and shape constructed according to my invention and showing
it adjusted for cutting squares.
Figure 2 is a section on the line A. B. of Figure 1 and
Figure 3 is a section on the line C. D. of Figure 1.
Figure 4 is a similar view to Figure 1 but showing the apparatus adjusted for
cutting diamonds and octagons.
Figure 5 is a plan and
Figure 6 is a side elevation of a stop-piece to be used when cutting octagons.
Similar letters in all the figures indicate similar parts.
In carrying my invention into practice I construct a board or table a capable
of being mounted on suitable supports or trestles and having an aperture b
therein over which the glass to be cut projects, and through which the pieces
fall as they are severed. The board a is provided with a rebated edge c lined
with metal forming a guide for the edge of the glass as it is fed forward. An
arm or rod formed of two separate parallel pieces or strips d and e placed one
above the other, projects across the aperture 6 being attached at one extremity
to the board a by means of a screw threaded clamping stud or centre-pin while
the other end of the arm or rod d. e carries a ping which moves in a segmental-
guide formed of metal or other suitable material graduated, if desired, to indicat :
the angle to which the bar is adjusted.

page_text: The pin g is provided with a screw thread to receive a clamping nut i by means
of which, in combination with the clamping stud or centre pin f the arm de can be
fixed in any desired position.
The lower strip e of the arm is preferably formed of steel in order to secure
greater rigidity, a space; being left between the two strips sufficiently wide to
admit of the insertion of the glass indicated by dotted lines a' in Figures 1 and 4,
the upper strip d acting as a guide for the cutting-tool and being provided with
a sliding-plate which can be moved along it to any required position and
having a projection which acts as a stop to prevent the diamond before the
cut is made slipping over the sharp edge of the glass. The plate k is fixed by
means of a pin m working in a slot n and a clamping nut o on the pin m.
A stop-piece the position of which can be readily adjusted is provided in
combination with the arm d. e. so that if the glass a¹ is pushed up against this stop-
piece before each cut, the sizes of the pieces of glass will be constant. This
stop-piece consists of a short arm p capable of revolving or swivelling upon a centre-
pin or stud which moves in a slot or guider so that the position of the said stop
can be adjusted to the size of glass to be cut. s is the clamping nut for fixing the
arm P when it has been adjusted. An arm or link t is preferably connected to the
extremity of the stop p so that greater rigidity can be secured, this arm or link
being fixed by means of a screw threaded pin u fixed in the board a and passing
through a slot in the arm or link and having a winged nut we provided thereon
for clamping the arm or link securely.
A receptacle or shoot is provided beneath the aperture 6 for the reception of
the pieces of glass as they are detached from the range.
The shoot is adapted to slide in runners y on the under side of the board a to
allow of its position being altered to suit the varying positions of the arm d. e.
1
In order to provide for the arm d. e. being adjusted to a more acute angle than
can be attained from the centre f, I make it with a second hole whereby the
centre can be changed.
To make use of the apparatus for cutting glass into squares the arm d. e. must be
fixed at a right angle to the rebated edge e of the board a as shewn in Figures 1
and 2 and the stops k and p must be moved to the required positions according to
the size of the pieces of glass to be cut and there fixed, the stop being placed at a
right-angle to the edge of the board a. The upper end of the slope of the shoot a
must be brought immediately beneath the front edge of the arm d. e. and the range
of glass a passed through the space j. until it abuts against the stop p, care
The workman then
being taken to keep its edge close against the rebated edge.
places the cutting tool against the projection of the stop k and draws it across the
glass a', using the upper part d of the arm as a guide for the tool.
It will be seen that the front edge of the part e of the arm projects slightly
beyond that of the part d; by this means the cut is made exactly in a line with the
said edge of the part e and the piece of glass can easily be severed by simply
pressing upon it and will slide down the shoot z into a suitable receptacle not shown
in the drawing. The range a' is then pushed forward and another square is cut off*
in a similar manner and so on.
For cutting glass into diamond shaped pieces, the arm d. e. and the stop must
be adjusted to the required angle as shewn in Figure 4 when a series of oblique
cuts can be made in the range a' so as to form a diamond at each cut.
When cutting octagons I make use of the attachment shewn in Figures 5 and 6.
This attachınent consists of an arm z adapted to be fixed to the stop p by means of
the pivot pin of the arm or link t. The said pin for this purpose is screw
threaded and screws into the stop p and is provided with a shoulder c' whereby the
part of the arm can be clamped to the stop p in the position shewn by the
dotted lines in Figure 4. The object of this arm z is to form an extension of
the stop p so that it may constitute a stop for the square e¹ of glass from which the
octagon is being cut. When one corner of the square e' has been cut off, it is

page_text: shifted round for another corner to be cut off and so on until all the four corners
have been, severed.
Although I have only described the use of my apparatus for cutting glass into
squares, diamonds, and octagons, it will be obvious that glass can be cut of various
other shapes by simply. altering the positions of the parts..
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.). An apparatus for facilitating the cutting of glass into pieces of predetermined
size and shape comprising improved means whereby the pieces of glass may be
severed from a range without the necessity for lifting it, guides and stops for
ensuring the cutting of the glass to the correct form and size, and an adjustable
stop for preventing the diamond being accidentally forced or slipped over the sharp
edge of the glass before the cut is made, substantially as hereinbefore described.
(2.) In apparatus for facilitating the cutting of glass into pieces of predetermined
size and shape the peculiar construction of the adjustable arm d. e. in combination
with a board and a shoot as described for enabling pieces of glass to be severed
from a range without the necessity for lifting the latter substantially as hereinbefore
describe and illustrated in the accompanying drawings.
(3.) In apparatus for facilitating the cutting of glass into pieces of predetermined
size and shape, the combination of the herein described guides and stops for

size and shape, the use of an adjustable stop such as k for preventing the diamond
being accidentally forced or slipped over the sharp edge of the glass before the cut
is made substantially as hereinbefore described and illustrated in the accompanying
drawings.
(5.) The improved apparatus for facilitating the cutting of glass into pieces of
predetermined size and shape hereinbefore described and illustrated in the accom-
panying drawings.
