Improvements in Link or Jointed Belting.
We JEROME MAGNIN and SEXTIUS RICBOURG both of Lyons (Rhone) France
Manufacturers, do hereby declare the nature of this invention to be as follows:-
Link or jointed belting as ordinarily made is formed of pieces or links of leather,
wood or other material connected together at right angles to their length by metal
rods so as to form a sort of endless chain. Generally the rod has a head at one end
and is rivetted at the other against a counter rivet.
The holes of the links or pieces at the sides of the belting are countersunk to receive
the head and the counter-rivet. The metal rod offers a certain resistance to bending
and its rigidity is increased in consequence of its connection with the links, the result
of which is that the belting offers in the transverse direction great resistance to bending
and that it does not adapt itself readily to the curve of the pullies; it has little
adhesion and soon gets out of shape.
In order to overcome this objection various methods have been employed; for
example a concave form has been given to the surface of the belting so that the rod has
not to submit to any bending. Also the belting has been divided in its width into several
bands connected by a piece of leather of U-form or by oblique links, but none of these
methods have proved satisfactory.
The object of our invention is to make link belting flexible transversely. For this
purpose instead of a rod we employ for the connection of the links or pieces a metal
cord or rope formed of wires of great resistance. This cord can be made of any suit-
able metal such for example as wires of iron, steel, brass, bronze of various descriptions
or delta metal. It can be galvanized, coated with copper or covered with any suitable
coating. The description of rope and the gauge of the wires can be varied as desired.
The surface of the rope can be such as in ordinary metal ropes, or it may be a smooth
surface; the form of the section of the wires can therefore vary. We can employ
ropes or cords of any desired length according to circumstances, that is to say we can
limit them to the width of the belting by terminating them with a head and a counter-
rivet or other means at each edge, or we can fold the ropes or cords over the edges of
the belting first in the direction of the length and afterwards in the transverse
direction, embedding them or not in the side links so that a certain length of rope can
connect a greater or less number of links and form a greater or less length of belting.
Sometimes we place on the rope between each link or between a certain number of
links washers or separating pieces of form, thickness and material such as may be
found suitable so as to increase the flexibility of the belting. Also we sometimes add
at each side of the link belting a cover piece or joint to suppress the breaks of continuity
between the links and thus allow the belting to be readily moved by clutches. The
cover pieces may be made of leather or other material of any suitable thickness; they
may be as wide as the thickness of the belting or of somewhat less width; they can be
of uniform width throughout their length or have a reduced width at the bending
points. They may be of square, rectangular, circular or other section; they may be
perforated and receive the heads which form the ends of the rods or ropes or have
longitudinal lodgements to receive the folded rope. Or they can be fixed externally
and cover these same heads or the folded parts of the rope. They can be fixed to the
links by screws, rivets, stitching or otherwise. The cover pieces can be formed of
several longitudinal bands fixed to each other and to the links by like means.

Improvements in Link or Jointed Belting.
We JÉRÔME MAGNIN and SEXTIUS RICBOURG both of Lyons (Rhone) France,
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 :-
Link or jointed belting as ordinarily made is formed of pieces or links of leather,
wood or other material connected together at right angles to their length by metal
rods so as to form a sort of endless chain. Generally each rod has a head at one end
and is rivetted at the other against a counter rivet. The holes of the links or pieces
at the sides of the belting are countersunk to receive the head and the counter rivet.
The metal rod does not readily bend and its rigidity is increased in consequence of its
connection with the links, the result of which is that the belting offers in the transverse
direction great resistance to bending and that it does not adapt itself readily to the
curve of the pullies; it has little adhesion and soon gets out of shape.
In order to overcome this objection various methods have been employed, for
example a concave form has been given to the surface of the belting so that the rod
has not to submit to any bending. Also the belting has been divided in its width into
several bands connected by a piece of leather of U-form or by oblique links, but none
of these methods have proved satisfactory.
The object of our invention is to make link belting flexible transversely. For this
purpose instead of a rod we employ for the connection of the links or pieces a cord or
rope formed of wires of great resistance. This cord can be made of any suitable metal,
such for example as wires of iron, steel, brass, bronze of various descriptions or delta
metal. It can be galvanized, coated with copper or covered with any suitable coating.
The description of cord and the gauge of the wires can be varied as desired. The
surface of the cord can, for example, be such as in ordinary metal cords, or it may be
a smooth surface; the form of the section of the wires can therefore vary. We can
employ cords of any desired length according to circumstances that is to say we can
limit them to the width of the belting by terminating them with a head and a counter
rivet or other means at each edge or we can bend the cords at the edges of the belting
in the direction of the length and carry the ends in the transverse direction through
the rows of links, embedding them or not in the side links so that a certain length of
cord can connect a greater or less number of links and form a greater or less length of
belting. Sometimes we place on the cord alternately with the links or at intervals
comprising a certain number of links, washers, plates or separating pieces of form,
thickness and material such as may be found suitable so as to increase the flexibility
of the belting. Also we sometimes add at each side of the link belting, cover or joint
pieces to suppress or fill up the breaks of continuity between the links and thus allow
the belting to be readily moved by clutches. The cover pieces may be made of leather
or other material of any suitable thickness; they may be as wide as the thickness of
the belting or of somewhat less width; they can be of uniform width throughout their
length or have a reduced width at the bending points. They may be of square,
rectangular, circular or other section; they may be perforated and receive the heads
which form the ends of the rods or cords, or have longitudinal lodgments to receive
the folded cord. Or they can be fixed externally and cover these same heads or the
folded parts of the cord. They can be fixed to the links hy screws, rivets, stitching or
otherwise. The cover pieces which are also applicable to link belting in which the
links are connected together by rods, can be formed of several longitudinal bands fixed
to each other and to the links by like means.
When the wire cords are made double that is to say when the same piece or length
of cord is bent and made to connect two transverse rows of links, we sometimes place
the links so that all the ends of one transverse row, see A in the annexed figures, come
end to end with the links of the next adjoining transverse row B, instead of the
arrangement being of a sort of quincunx form as usual, and in order to keep the two

page_text: transverse portions of the cord properly apart we can connect them by interposing
alternately with the rows of links or at intervals, metal plates or pieces E through
which the cords pass; the outside plates can be countersunk to receive the heads and
rivetted ends of the cords. The metal plates or pieces E practically constitute some of
the links of the belting.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim, in
respect of link or jointed belting is :-
1. The connection of the links by means of wire cords with or without the inter-
position of washers, plates or separating pieces, as and for the purpose set forth.
2. The addition to the link belting of cover or joint pieces at the sides to suppress
or fill up the breaks of continuity between the links, as and for the purpose set forth.
3. Constructing link or jointed belting, substantially as hereinbefore described.
