PROVISIONAL SPECIFICATION.
Improvements in Glaziers' Wheel Glass Cutters.
JOHN HEWITT 19 Cambridge Street Sheffield Glaziers' Wheel Glass Cutter
Maker do hereby declare the nature of this invention to be as follows:
-
The first part consists in mounting the glass cutting wheel in a handle shaped in
such a manner the operator can see better what he is doing and yet have a more
perfect controll over the tool during cutting the glass, whilst the wheel being
mounted just right for cutting glass, is out of the way when "tapping" or breaking it.
This is effected in the following manner: The front part carrying the wheel is bent
in a curve, the top of which can be used as a "tapper," behind this curve is a finger
rest on which the operator places a finger when useing the tool; behind this is the
handle proper, which grasped in the hand. The whole may be made of one
piece of metal, or with the front curved piece of metal and the back part of wood.
The second part relates to the "diamond" pattern wheel glass cutter and consists
in fitting a steel or hard metal bearing in the wooden handle at the bottom of the
hole the tang or shank of the head piece revolves in, the end of which presses
against this bearing instead of the collar on the shank against the wood handle, as
at present in use; the improvement allowing of a reduction of friction as the head
piece carrying the glass cutting wheel revolves in the handle and so reducing the
risk of the wheel running across the glass and spoiling it.

Improvements in Glaziers' Wheel Glass Cutters.
JOHN HEWITT of No. 19 Cambridge Street Sheffield Glaziers' Wheel Glass
Cutter Maker 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 :-
The first part consists in mounting the glass cutting wheel in a handle shaped in
such a manner the operator can see better what he is doing and yet have a more
perfect controll over the tool during cutting the glass; whilst the wheel being
mounted just right for cutting glass, is out of the way when "tapping" or breaking it;
this is effected in the following manner. The front part A, Fig. 1 carrying the
wheel F, Figs. 1 and 2, is bent in a curve, the top of which B, can be used as a
"tapper" behind this curve is the finger rest C, Fig. 2, on which the operator
places a finger when useing the tool, behind this is the handle proper, which is
grasped in the hand.
The whole may be made of one piece of metal such as iron brass etc., or with the
front curved piece A, of metal with a tang to go into the handle D, and the back
part E, D, of wood, D, being wood with ferrule E, of brass or iron.
Fig. 1, shows it in elevation full size 5 inches long, which I find the most
convenient size although a little larger or a little smaller does not matter.
Fig. 2 shows the ground plan with the cutting wheel at F, which is an ordinary
glass cutting wheel, revolving on a pin in the usual way.
Fig. 3, shows it in perspective reduced in size.
Fig. 4, shows the mode of useing it.

page_text: The second part relates to the "diamond" pattern wheel glass cutter, and consists
in fitting a steel or hard metal bearing in the wooden handle at the bottom of the
hole the tang or shank H, Fig. 5, of the head piece carrying the glass cutting
wheel F, revolves in, the end of which presses against this bearing instead of the
collar on the shank against the wood handle as at present in use, the improvement
allowing of a reduction of friction, as the head piece carrying the glass cutting
wheel F, revolves in the handle and so reducing the risk of the wheel running
across the glass and spoiling it. I prefer to make this "bearing" of hardened
steel, in the shape of a round disc, which is made a trifle larger than the hole the
shank H, revolves in, and which is driven tight to the bottom of the hole in the
wooden handle.
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.
1st. Substantially what I set forth and describe in my first part and show in
Figs. 1, 2, 3, and 4, which allows a glass cutting wheel to be mounted or fixed in a
more convenient manner and making a tool better adapted for cutting glass.
2nd. The combination of a glass cutting wheel, with a handle shaped or formed
as shown in Figs. 1, 2 and 3, whether made in metal or wood and metal.
3rd. The metal bearing, substantially as described and set forth in my second
part and shown in Fig. 5.
