PROVISIONAL SPECIFICATION.
Improvements in or relating to the Cutting of Glass and Apparatus
therefor.
I, LEON HAVAUX, of St. Ghislain, in the Kingdom of Belgium Engineer, do
hereby declare the nature of this invention to be as follows:-
This invention consists of a process for cutting glass and a series of arrangements
enabling the fire-proof rings between which the annular cutter is confined while
being heated by the electrical current, to be dispensed with, and small insulating
and fire-proof blocks to be used in their stead; these blocks being retained between
vertically and horizontally movable jaws or grippers, which permit the adjustment
of annular cutters of varying diameters to the desired height or level.
The cutter instead of being compressed between two flat fire-proof rings, is only
held at four points i.e. between nuts adjustable upon uprights at the base of which
are situated the electrical conductors and by the before-mentioned small blocks
gripped by jaws. The nuts have extensions in the shape of slotted and screw-
threaded sleeves of slightly tapering shape, which may be firmly clamped against
the uprights by means of nuts so that the electrical current has first-class contacts
only to traverse in its course.
The jaws are slotted, and in the slots are located the before mentioned small
blocks firmly secured in position by means of screws. The gripping jaws terminate
in tail-pieces by means of screws in runners or sleeves adjustable on uprights and
which may be secured by means of screws.
The cutter may also be adjusted to the desired level by placing the article to be
cut, upon a vertically adjustable rest or stand. The cutter is firmly retained on
the top of the uprights by screws. The grippers are also firmly secured within
recesses provided at the top of uprights. The article to be cut is placed upon a
support the central rod of which is adjustable in a sleeve and may be tightened or
secured therein by means of a set-screw. The plate is thus adapted to turn upon
its foot or rest whereby the cutting operation is facilitated and perfectly neat cuts
are obtained. Rotary motion is imparted by hand. It may be similarly produced
in another form of the apparatus wherein the article to be cut is itself rotated.
The construction of the apparatus may further be modified in various ways
without departure from the principle of the invention.

COMPLETE SPECIFICATION.
Improvements in or relating to the Cutting of Glass and Apparatus
therefor.
I, LÉON HAVAUX of St. Ghislain in the Kingdom of Belgium Engineer, 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 which is based upon that described in my Specification No. 17691
dated October 4th 1892, consists of a series of arrangements enabling the fire-proof
rings between which the annular cutter is confined while being heated by the
electrical current, to be dispensed with, and small insulating and fire-proof blocks
to be used in their stead; these blocks being retained between vertically and

cutters of varying diameters to the desired height or level.
In the accompanying drawings
Figures 1 and 2 illustrate the improved arrangements. The cutter L, instead
of being compressed between two flat fire-proof rings, is only held at four points
i.e. between nuts e adjustable upon uprights or standards M, at the base of which
are situated the electrical conductors K K', and by small blocks B B¹ gripped by
the jaws P. The nuts e have extensions in the shape of slotted and screw-threaded
sleeves of slightly tapering shape, which may be firmly clamped against the
uprights M by means of the nuts so that the electrical current has first-class
contacts only to traverse in its course.
The jaws P are slotted, and in the slots are located blocks B B' firmly secured
in position by means of screws W. The gripping jaws terminate in tail-pieces
secured by means of screws V in runners or sleeves m adjustable on the uprights or
standards C and which may be secured by means of the screws V¹.
The cutter L may also be adjusted to the desired level by placing the article to
be cut, upon a vertically adjustable rest or stand. Figures 3 and 4 of the drawings
illustrate this arrangement. The cutter L is firmly retained on the top of the
uprights M by screws e. The grippers P are also firmly secured within recesses
provided at the top of the uprights C. The article X to be cut is placed upon a
support D the central rod F of which is adjustable in a sleeve and may be tightened
or secured therein by means of a set-screw Q. The plate D is thus adapted to turn
upon its foot or rest whereby the cutting operation is facilitated aud perfectly neat
cuts are obtained. Rotary motion is imparted by hand. It may be similarly
produced in the other form of apparatus wherein the article to be cut is itself
rotated.
The construction of the apparatus may further be modified in various ways
without departure from the principle of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In apparatus such as described supporting a circular metal plate or strip such as
Lof German silver or other bad conducting metal by metal standards such as M serving
as conductors and standards C having jaws P and blocks B for allowing of circular
plates or strips L of any suitable diameters to be placed at suitable heights for
which purpose the clamps e for holding the cutter on the conducting columns are
also adjustable substantially as described and illustrated in the accompanying
drawings.
2. In apparatus such as described the combination with a circular metal plate or
strip such as L of bad conducting metal and standards such as C and M (Fig. 3) of
an adjustable plate or table such as D substantially as described and illustrated in
the accompanying drawings.
3. The combination and arrangement of parts constituting the complete glass
cutting apparatus substantially as described and illustrated in Figs. 1 and 2 of the
accompanying drawings.
4. The combination and arrangement of parts constituting the complete glass
cutting apparatus substantially as described and illustrated in Figs. 3 and 4 of the
accompanying drawings.
