HENNELL STEVENS, OF BRAZOIIA, TEXAS.
IMPROVEMENT IN APPARATUS FOR CUTTING GLUE.
Specification forming part of Letters Patent No. 16,01, dated October 11, 1875; application filed
May 15, 1875.To all wchom it may concern
Be it known that I, HENNELL STEVENS, of
Brazoria, county of Brazoria and State of
Texas, have invented an Improvement in
Slicing and Cutting Glue; and I do hereby
declare that the following is a full, clear, and
exact description thereof, reference being had
to the accompanying drawing making part
of this specification, in which is shown a re-
ciprocating frame, B, which carries a glue-
cutting wire or wires, a, connected to a mag-
netic battery, A, by covered wires b b, and
provided with glass insulators e e at the point
where the wires pass through the frame B.
This drawing illustrates about the relative
sizes of the wires a and b.
The nature of my invention consists in
wires, heated by electric or galvanic currents,
for cutting or slicing glue; said wires being
applicable to any glue slicing or cutting
machine in use, and effectually overcoming
the difficulties heretofore experienced in cut-
ting glue.
In the drawing, I have shown a galvanic
battery, A, and an apparatus, B, adapted
for slicing or cutting glue. The parts A and
B may be constructed and -combined in any
other proper manner than that shown, but
this is a practical plan and sufficiently illus-
trates my invention.
In preparing glue for drying, the gelati-
nous solution, ater being boiled down to
such a consistency that it will set on cool-
ing, is poured into rectangular boxes and al-
lowed to become solid. It is then removed
from these boxes and cut into thin sheets by
means of the fine wires a, stretched very
tightly in a frame and actuated by suitable
machinery, which reciprocates the wires and
causes them to pass through the glue. The
wires, by being heated by the galvanic bat-
tery A, will glide through the glue with the
greatest ease and rapidity, whereas, hereto-
fore, when the wires have not been heated,
the resistance and tenacity of the glue have
been so great that considerable power was
required, and the mass of glue, in order to
save the wires from being broken and to in-
sure a clean cut, had to be cut into narrow
blocks.
In practice, the wires of any machine inuse may be heated, say, to about 2120, by
means of an electric current, generated by a
battery of sufficient power.
The same invention may be applied to ma-
chines for cutting soap and similar tenacious
articles, anti by its use the operation will be
pIerformed more rapidly and the necessity for
using powerful machinery and steam-power
will be avoided.
In most of the glue-cutting machines, the
block of glue or size is placed in a frame and
raised by ratchets, as the cutting-wires re-
ciprocate backward and forward, and it will
be understood thatI make no material change
in the glue-cutting or other machines which
cut substances with wires, except providing
the insulators at the points where they pass
through the frame, and' attaching a battery
of sufficient power for heating the wires to
a temperature of about 2120, in which state
they will glide through the glue with scarcely
any resistance.
I have shown a frame with a single wire,
to be used by hand, but any number of wires
may be combined and actuated, either by
hand or steam-power.
- Either brass or platinum wires may be used,
and any machine now in use can be fitted
with my improvement at a trifling expense.
I am aware that it has been proposed to
burn logs in two by means of electrically
heated wires; but I am not aware that a finue
wire, applied in a glue-cutting frame, and con-
nected with a galvanic battery, has ever been
devised for the purpose of fusing the glue at
the lines of separation for the purpose of
avoiding the difficulty experienced from the
sticking of the glue to the wire. I do not
claim electrically-heated wires as a new in-
vention, disconnected from the glue or soap
cutting frame.
What I claim as my invention is-
The combination of a glue-cutting frame,
having cutting-wires applied across it, con-
ducting-wires, and a galvanic battery, sub-
stantially as herein described.
