Improvements in Apparatus for Sawing, Cutting, Dressing, or
Polishing Stone, Marble, or other Material.
I PAULIN GAY, of 1 Boulevard St. Denis, Paris, France, Engineer do hereby
declare the nature of this invention to be as follows:-
My invention consists in constructing saws, cutters or similar tools in the form
of links or short lengths or pieces jointed together, some or all of such lengths or
pieces constituting the active parts. The saw or other tool may be either continuous
or reciprocating and it may be caused to work horizontally, vertically or obliquely.
The links or pieces that connect the saw blades or cutters may be formed of steel
blades, wire gauze, or simple rings, or the sawing or cutting blades can be jointed
directly to each other. In all cases these blades can be made with or without teeth;
they can be straight or curved and provided or not with holes or cavities for carrying
sand or analogous material. They may or may not be surmounted by a weight for
the purpose of increasing their penetration into the material to be sawn, and they may
carry blocks or pieces of a grinding substance for dressing, polishing, &c.
I will describe, by way of example, several forms of my jointed saws or tools.
In one form connecting links made of flexible steel band are attached by rivets or
similar devices to the short cutters or saw blades. The cutters or blades are each
composed of two cheeks of sheet metal having round or other shaped holes for
holding the sand, these holes being so arranged in rows that when the first row is
worn away another row appears at the edge of the blade; the blades can be worn
nearly up to the connecting links and if these are at the middle of the blades the blade
can then be reversed so as to bring the other edge into position for work.
In another form the connecting links are made of wire gauze and the cutters are
elliptical; the front and back curves allow of the free passage of the sand.
In another form the connecting links are made of strips of steel bent into loops

page_text: or eyes at the ends these loops or eyes being attached by pins or studs to the cutters.
This form of connection allows the cutters a torsion movement like that of the saws,
called in France "chantourner," that is to say, they will saw round.
In another form the pieces connected by the links are faced with pieces of grinding
material such as are employed for wearing away stone or filing or polishing metal, &c.
In another form the cutters are connected directly to each other by pins or rivets.
In another form the cutters are connected by joints resembling elbow joints.
In another form the jointed pieces receive tools for shaping, grooving, &c.

I PAULIN GAY, of 1 Boulevard St. Denis, Paris, France, 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:-
My invention consists in constructing saws, cutters or similar tools of links or short
lengths or pieces jointed together, some or all of such lengths or pieces constituting
the active parts. The saw or other tool may be either continuous or reciprocating and
it may be caused to work horizontally, vertically or obliquely.
The links or pieces that connect the saw blades or cutters may be formed of steel
blades, wire gauze, or simple rings, or the sawing or cutting blades can be jointed
directly to each other. These blades can be made with or without teeth, they can be
straight or curved and provided or not with holes or cavities for carrying sand or
analogous material. They may be surmounted by a weight for the purpose of
increasing their penetration into the material to be sawn and they may carry blocks
or pieces of a grinding substance for dressing, polishing, &c.
I will describe by way of example and with the aid of the annexed drawings
several forms of my jointed saws or tools. Figure 1 represents one example in which
connecting links a made of flexible steel band are attached by rivets or similar devices
to the short cutters or saw blades. In the figure I have purposely shown three
different types or forms of cutter or blade, but it is not intended to use them in
combination. The cutter or blade A is composed of two cheeks of sheet metal having
round holes for holding the sand, these holes being so arranged in rows that when the
first row is worn away another row appears at the edge of the blade; the blades can
be worn nearly up to the connecting links and if these are at the middle of the blades
the blade can then be reversed so as to bring the other edge B into position for work.
The cutter or blade D differs from that marked A only in the form of the holes which
are triangular instead of round. The cutter or blade C is simply a toothed cutter and
is particularly adapted for sawing soft stone.
In Figure 2 the connecting links a are made of wire gauze and the cutters G G are
elliptical; the front and back curves allow of the free passage of the sand.
In the example shown in Figure 3 the connecting links a are made of strips of
steel bent into loops or eyes at the ends these loops or eyes being attached by pins
or studs to the cutters G. This form of connection allows the cutters a torsion
movement like that of the saws called in France "chantourner," that is to say, they
will saw round.
In the example shown in Figure 4 the pieces G G connected by the links a are faced
with pieces g,g of grinding material such as are employed for wearing away stone or
filing or polishing metal, &c.

page_text: In Figures 5 and 6 the cutters G G are connected directly to each other by pins or
rivets h, h. In Figure 6 the joints formed by the rivets are so placed as to leave a
large surface of the plates G G for wear.
In Figures 7 and 8 the cutters G G are connected by joints m, m resembling elbow
joints.
In the example shown in Figure 9 the jointed pieces G G receive tools n, n for
shaping, grooving, &c.
In Figure 10 the jointed cutters are formed with triangular holes p, p and
teeth 9, 9.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim, in
respect of apparatus for sawing, cutting, dressing or polishing stone, marble or other
material, is :-
1. The construction of saws, cutters, or dressing or polishing tools, of links or short
lengths or pieces jointed together whether some or all of such lengths or pieces
constitute the active parts, substantially as set forth.
2. The several arrangements represented in the annexed drawings and hereinbefore
described.
