A PROCESS OF AND APPARATUS FOR ANNEALING HARDENED STEEL WIRE USED
IN THE MANUFACTURE OF FILLET AND SHEET-CARDS, communicated to me from
abroad by La Société Veuve A, Miroude et Compagnie, of 1, Boulevard Saint-
Denis, Paris, France, to be as follows:-
This Invention has for its object a process of and apparatus for annealing
hardened steel wire, used in the manufacture of fillet-cards and sheet-cards, said
annealing taking place on the card-setting machine, and during the manufacture of
the cards.
For this purpose, a small gas or other lamp,-burner, or blowpipe is employed
(or the action of an electric current) and is arranged in combination with the
card-setting machine; the hardened steel wire coming from the roller, from which
it is unwound, passes through the gas lamp and thence to the machine there to
form the teeth of the card.
When the wire passes through the lamp without being stopped, it does not
undergo any annealing; but if it be stopped for an instant, this instant suffices
for annealing the wire at the place where it finds itself opposite the flaine.
It is on this principle that this invention is founded. I take advantage of the
moment of the natural' stoppage, produced in the advance of the wire on to
the card-setting machine, at the moment of formation of the tooth of the card,
to effect the annealing during this stoppage.
The annealed portion is therefore repeated on the wire at very regular intervals
or spaces, corresponding to the length of wire necessary for the formation of
a tooth; hence, it follows that the annealed portion of the wire is presented with
great regularity to the machine for the purpose of there forming the base of the
tooth, and the two feet up to where the "croc," or hook, commences, which latter
alone remains in the original condition of the wire.

page_text: This operation has for result the removal of the hardness or the "spring" of the
wire at the place annealed; consequently, the operation of card-setting is better
effected and is more. regular. On the other. hand, the teeth of the card present
more solidity.
The lamp, by preference, consists of a vertical tube furnished at its lower part
with a nozzle, over which is fitted a rubber tube supplying the gas.
The lamp,
or vertical tube, is fixed to any suitable support, and is provided, at or about its
lower part, with air holes. Above the lamp is a cap, also provided with air holes,
and with two small orifices through which latter the wire to be, annealed passes
from the roller to the card-setting machine.

A PROCESS OF AND APPARATUS FOR ANNEALING HARDENED STEEL WIRE USED
IN THE MANUFACTURE OF FILLET AND SHEET CARDS, communicated to me from
abroad by La Société Veuve A Miroude et Compagnie, of 1 Boulevard Saint-Denis,
Paris, France, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawings, and to the letters and figures marked thereon, that
is to say:
This Invention has for its object a process of and apparatus for annealing
hardened steel wire used in the manufacture of fillet and sheet cards, the said
annealing taking place on the card-setting machine and during the manufacture of
the cards.
For this purpose I employ a small gas or other lamp, burner, or blow-pipe (or
even the action of an electric current), arranged in combination with the card-
setting machine. The hardened steel wire, as it comes from the roller from which
it is unwound, passes through the gas lamp and thence to the machine there to
form the teeth of the card.
When the wire passes through the lamp without being stopped, it does not
undergo any annealing, but if it be stopped for a very short time, such stoppage is
sufficient to anneal the wire at the place where it.is opposite the flame.
It is on this principle that this invention is founded: I take advantage of
the, natural stoppage produced in the advance of the wire on to the card-setting.
machine, at the moment of the formation of the tooth of the card, to effect the
annealing during this stoppage.
The annealed portion is therefore repeated on the wire at very regular intervals
or spaces corresponding to the length of wire necessary for the formation of a
tooth; hence it follows that the annealed portion of the wire is presented with
great regularity to the machine for the purpose of there forming the base of the
tooth, and its two feet up to where the "croc" or hook commences, which latter
alone remains in the original condition of the wire.
The result of this operation is the removal of the hardness or the "spring" of
the wire, at the place annealed, consequently the operation of card-setting is
better. effected and is more regular. On the other hand, the teeth of the card offer
more solidity.
The accompanying drawing shews by way of example an arrangement of gas
lamp which is combined with the card-setting machine for effecting the annealing
according to this invention. Fig. 1, is a vertical section and Fig. 2 a plan of the.
said lamp.
This lamp consists of a vertical tube a, furnished at its lower part with a
nozzle b, over which is fitted a rubber tube c, supplying the gas. This tube a is
fixed to a suitable support d, and it is provided at or about its lower part with air
holes f. Above the tube a, is a cap, provided with several air holes 9, g, and with
two smaller orifices h, h, through which latter the wire m to be annealed passes
from the roller to the card-setting machine.
I wish it to be understood that I do not limit myself to any special arrangement
of lamp, blow-pipe or burner, seeing that it is optional for me to use gas.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The process, substantially as herein described, of annealing hardened steel
wire used in the manufacture of fillet and sheet cards, and in which process the
annealing takes place on the card-setting machine during the manufacture of
the cards.
2. The special construction of gas lamp as described and shewn and the use
of same in combination with a card-setting machine for the purpose specified.
