Improved Method of and Means for Heating Curling Tongs, Crimping
Irons, and the like.
We, JAMES WILLIAM GREENWOOD, Electrician, of Stoney Royd Terrace,
Whitegate, Halifax, and WALLACE CROSSLEY, Mechanic, of Delph Hill, Skircoat,
Halifax, both in the County of York, do hereby declare the nature of this inven-
tion to be as follows:
The object of our invention is to heat curling tongs, crimping irons and the
like by electricity, and to so construct such curling tongs and the like so that
they are easily manipulated and the heat maintained at one uniform pitch, while
in use.
We preferably construct our curling tongs of brass or other suitable metal,
with the bottom or fixed jaw in tube form, the upper jaw is pivotted or hinged
and kept in contact with the fixed jaw by a suitable spring, this curling tong
is attached to a suitable hollow wood handle. Within the fixed jaw we place a
high resistance wire insulated which is heated by the electric current from any
suitable supply, this high resistance wire is connected to two conducting wires
which pass along the wood handle, these wires are also attached to a suitable
swivel collar to which is attached the conducting wire from the supply, so that
when the tongs are being used, this swivel collar prevents the conducting wire
from becoming twisted or otherwise damaged, besides allowing of a free manipu-
lation of the tongs or the like.

Improved Method of and Means for Heating Curling Tongs, Crimping
Irons, and the like.
We, JAMES WILLIAM GREENWOOD, Electrician, of Stoney Royd Terrace,
Whitegate, Halifax, and WALLACE CROSSLEY, Mechanic, of Delph Hill, Skircoat,
Halifax, both in the County of York, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
The object of our invention it to heat curling tongs, crimping irons and the
like, by electricity, and to so construct such curling tongs and the like, as to be

wires, and the heat maintained at one uniform degree while in use. Also such
tongs may be connected direct on to the supply without any intermediate resist-
ance or reducing appliance.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a longitudinal section of our improved curling tongs, showing method
of electrically heating same.
Fig. 2 is a plan view of our improved curling tongs.
Fig. 3 is an enlarged sectional view of part of fixed jaw or tube, showing
method of and means for electrically heating same.
Fig. 4 is an end view of handle showing method of attaching the conducting
wires.
We preferably construct our curling tongs, crimping irons and the like, of
brass or other suitable metal, and in the case of curling tongs, with the bottom
or fixed jaw A in tube form, the upper jaw B is pivotted or hinged and kept in
contact with the fixed jaw, by a suitable spring (, these tongs are attached to a
suitable hollow wood handle 1). Within the fixed jaw A, we place a high resist
ance appliance, consisting of preferably, a high resistance wire F', preferably of
manganin 002 guage, this wire is wrapped with silk and wound spirally around
a central wire core E, which acts as a stiffener, and is for inserting or withdraw-
ing the insulated appliance, within or from, the tube or fixed jaw A.
After the wire F has been wrapped spirally around the core, it is covered with
a layer of cement G, composed preferably of shellac and slate dust, then the
aforesaid wire is again wound spirally around this covering of cement, then
another covering of cement is used, this is continued alternately until four or
more wrappings of the wire has been employed, with an equal number of layers
of cement, according to the voltage employed; this appliance is then taken and
inserted within the fixed jaw A. which is previously filled with the aforesaid
eement in a plastic state, in this way the durability of the wire F is considerably
increased, as it is not subjected to atmospheric influence, so preventing oxidiza-
tion which has a great effect where frequent heating and cooling takes place.
The ends of this high resistance wire F, are connected to two conducting
wires H, which pass along the wood handle 1), and are soldered or attached to
suitable metallic collars J, mounted upon a neck of the handle D,
these collars J are kept rigid by means of a turned down part K,
resting or fitting within a slot L in the aforesaid neck, around these collars J,
swivel collars M, each collar having a peg or arm N, to which are attached
by nuts N, the conducting wires P, attached to any suitable supply the
collars M are encircled by a further wood collar R which also swivels and pre-
vents the operator coming in contact with the current.
The pegs, studs or arms N, are placed within a wood or other nonconducting
cover S, and for further covering up the connections, and for operating the
swivel, a suitable wood or other nonconducting nipple T is employed, which,
when using the tongs, is preferably placed between the third and fourth finger,
so that the conducting wires P do not become twisted or otherwise damaged, and
at the same time allows of a free manipulation of the tongs or the like.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we would have it
understood that we are aware curling tongs have been previously heated, by means of an
electric resistance, placed within hollow jaws or legs, but we declare that what
we claim is:-
1. Heating curling tongs, crimping irons and the like, by means of an electric
high resistance wire F, wound spirally within the tube or fixed jaw A, in com-
bination with an alternate layer of cement (t, and connected direct to the supply

page_text: 2. Heating curling tongs, crimping irons and the like, by means of an electric
high resistance wire F, wound spirally with an alternate layer of cement G,
within the fixed jaw or tube A, and connected to conducting wires H, attached
to insulated rings or collars J, collars M having pegs or arms N, to which are
connected the conducting wires P from the supply, such collars M, pegs N, and
collar R, swivelling upon the handle D, in the manner and for the purposes
set forth.
3. Electrically heated curling tongs, having an insulated swivelling collar M,
with pegs or arms N to which are attached or connected the electric supply,
such insulated parts having coverings of nonconducting material, and operating
in the manner and for the purposes set forth.
