Improvements in Electrical Warming Pans and like Articles.

I, WILLIAM BUCK, of 166, Queen's Road, Bayswater, London, W., Electro-
Metallurgist, do hereby declare the nature of this invention to be as follows:-
My invention relates to warming pans and warming appliances for warming
the human body, and its object is to heat such appliances electrically preferably by
means of incandescent lamps.
My invention consists in enclosing within the hollow of a heating appliance an
electrically heated body preferably one or more incandescent electric lamps which
lamps are coupled by suitable connections to any source of electric current.
In carrying my invention into effect as applied to a warming pan, in accordance
with one modification, I arrange a warming pan for a bed with the usual hinging
cover common to the older types of such appliances. Within the pan I provide a
inctal or other bridge piece and to this bridge piece I secure one or more electric lamp
sockets. I pass from these sockets double wires suitably insulated, through an
aperture leading to a hollow in the warming pan handle, and I carry the wires
through the axis of the handle, and connect them to a connecting plug of any.
known construction suitable for connecting the wires to a wall plug carrying the
electric mains. I fit within the sockets so applied inside the warming pan one
or more incandescent electric lamps of any usual construction. Sometimes I
provide holes in the sides of the pan to allow exit for heated air. This electric
warming pan is economical in the use of current, and the lamps when worn out
are easily replaced. At the same time, any desired supply of heat may be obtained
by providing a lamp or lamps of suitable dimensions.
In carrying my invention into effect as applied to a heater for use in warming
any part of the body by contact, I provide a spherical or egg-shaped receptacle
which I preferably divide into two parts, and connect the two parts by means of
a bayonet joint, by screws, or other contrivance. I provide one end of this instru-
ment with a tubular projection to serve as a handle, and I pass the wire to carry
the current up the centre of the tubular projection within a small inner tube. To
this small inner tube I screw the lamp socket, and I connect the lamp to the
socket in the usual way. This contrivance I find very useful for applying heat
to the human body in illness.
My invention may be applied to many different types of apparatus. It may be
used for foot warmers in carriages storage batteries being preferably employed to
generate current but in railway carriages I preferably supply the foot warmers
or carriage warmers with current from a dynamo on the engine. In the case of
foot warmers and for railway carriages coils may be used. Switches may be
arranged so that the passengers may switch the heat on and off as required.

I, WILLIAM Buck, of 166, Queen's Road, Bayswater, London, W., Electro-
Metallurgist, 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 relates to warming pans and appliances for warming the human
body, and its object is to heat such appliances electrically, preferably by means
of incandescent lamps.
My invention consists in enclosing within the hollow of a heating appliance an
electrically heated body, preferably one or more incandescent electric lamps
which lamps are coupled to any convenient source of electric current.
Referring to the accompanying drawings:-
:-
Figure 1 shows a perspective view of one form of warming pan having my
invention applied.
Figure 2 shows another form of warming pan in which the hot metal parts are
screened from the body.
Figure 3 shows a longitudinal section of part of Figure 2 on the line X X.
In carrying my invention into effect, as applied to a warming pan, according
to one modification as illustrated in Figure 1 of the accompanying drawings, I
arrange a warming pan A with the usual hingeing cover A¹ common to the older
types of such appliances. Within the pan I provide a metal or other bridge
piece B, and to this bridge piece I secure one or more electric lamp sockets C.
pass from these sockets double wires F, suitably insulated, through an opening
leading to the handle G of the warming pan, and I carry the wires through the
axis of the handle and connect them to a suitable wall plug F¹. I fit within the
sockets C one or more incandescent lamps D of any suitable construction. Some-
times I provide holes A2 in the sides of the warming pan to allow of the escape of
heated air.
The electric warming pan is economical in the use of current, and the lamps
when worn may readily be replaced. I prefer to employ cheap lamps or lamps
whose light giving power has deteriorated through continued use. Such lamps
although very inferior for giving light are useful for my invention since the
greater part of the energy supplied to them is transformed into heat. Any
desired supply of heat may be obtained by providing lamps of suitable resistance
or by varying the resistance of the circuit by means of a suitable resistance box.
In carrying my invention into effect as applied to a heater for warming any
part of the body, as illustrated in Figures 2 and 3 I provide a spherical or egg
shaped receptacle which is divided into two parts E and E. as shown in Figure 3.
The part E is attached in any suitable manner to the lamp-holder C of an ordinary
incandescent lamp D, and is provided with a heat-insulating handle G. The two
parts E and E' are connected by a bayonet joint or other suitable means. A second
casing E covers the part El and is constructed so that on turning the heat insulat-
ing knob I the casing E3 may be partially revolved on the inner casing E', so that
the holes A2 pierced opposite to one another through both inner and outer casings
may be closed or opened at will, according to the position of the knob I. I
vide a wire cover or other suitable casing J outside the heating chamber in
order to protect the body of the user from being burnt by contact with it. This
device I find very useful for applying heat to the human body in cases of illness.

page_text: 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 is:
1. The electrically heafed warming appliances substantially as herein before
described with reference to the accompanying drawings.
2. In an electrically heated warming appliance a perforated casing such as E¹
with a perforated cover such as E adapted to regulate the distribution of heat,
in combination with an insulated protecting cover such as J, all substantially
as and for the purposes set forth with reference to Figures 2 and 3.
