page_text: Improvements relating to the Sawing of Stone..
We, GRÉGORIE WINCQZ, and HUBERT MACHEPY, both of Soignies, in the Kingdom
of Belgium, Manufacturers, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to the sawing of stone and consists in ensuring the constant
introduction of hard material between a sawing wire and the stone by filling with
water, charged with the said material, a kind of vertical pocket or receptacle of
plaster, cement or the like formed against the stone throughout its entire height at
the place where the saw cut is to be made and on the side where the sawing wire enters
the stone. The hard material, which would usually be sand, is drawn in between the
stone and the wire particularly if the latter, is helicoidal wire, in the spirals of which
the said material would lodge.
We would observe that the sand will thus become located beneath the wire, that is
to say, in the place where it is required to grind or bite into the stone, whereas, when
the operator, as hitherto has been the practice, has poured water, mixed with sand,
upon the top of the stone, the greater part of the sand remains above the wire and is
practically wasted, only the finest grains, which pass over the sides and under the
wire, contributing with efficacy to the sawing action. It is therefore obvious that our
process allows of sawing much more quickly and with much less sand.
The pocket or receptacle is during the sawing operation continually fed with water
and sand from a suitable source and the helicoidal wire saws through the wall of the
pocket at the same time as it does through the stone.

WE, GRÉGOIRE WINCQZ and HUBERT MACHEPY, both of Soignies, in the Kingdom
of Belgium, Manufacturers, 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 :-
Our invention relates to the sawing of stone and consists in ensuring the constant
introduction of hard material between a sawing wire and the stone by filling with

our process allows of sawing inuch more quickly and with much less sand.
In the accompanying drawing,
Figure 1 is a vertical section of a piece of stone in course of being cut or sawn
according to our invention:
Figure 2 is an end elevation; and,
Figure 3 is a plan of the same.
A B is the pocket or receptacle which is a kind of half tube roughly made of
plaster, cement or other suitable material that can be easily applied against, and will
adhere to, the stone and which will hold the water and sand. It can if required,
however, be made of lead.
The pocket or receptacle is during the sawing operation continually fed with water
and sand from a suitable source and the helicoidal wire saws through the wall of the
pocket at the same time as it does through the stone.
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
In sawing stone in quarries, more particularly with the aid of helicoidal wire, the
application to the stone to be sawn of a vertical pocket or receptacle made of a
material which will adhere to the stone and which pocket or receptacle is filled with
water and sand or other suitable grinding material and is sawn at the same time as
the stone by the sawing wire which thus draws along the grinding material
beneath it into contact with the surface to be sawn, substantially as hereinbefore
described.
