Improvements in and relating to Foot-warmers and the like.
1, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
The present invention relates to foot-warmers and the like, and has for its object
to provide for expeditiously heating the same.
This heating is effected rapidly and at the desired moment by the projection of a
certain volume of water contained in a part of the foot-warmer upon a proportionate
volume of lime previously introduced at the bottom of the said foot-warmer.
The improved apparatus comprises one or more water reservoirs placed at one of
the extremities of the foot-warmer. These reservoirs terminate in a point and
present at this point a hole of small diameter which may be opened by means of a
valve in the form of a needle under the action of a spring, which permits the flow
of the water into the several compartments of the foot-warmer.
I may provide the foot-warmer with two compartments and with two water
reservoirs at the upper part of the foot-warmer, each of these reservoirs being
arranged at the top of a compartment of the body of the foot-warmer, with the
object of ensuring a longer duration in the operation of the apparatus.
The body of the foot-warmer contains a suitable quantity of lime; it is divided
into two compartments separated by a partition, and is closed by a cover by means
of a packing of hollow india-rubber. This cover is held on the one hand by means
of a hook extending below a cap or link, and on the other hand by means of a stop
articulated to the cover and the upper extremity of which takes below a stud on
the body of the foot-warmer.
The aforesaid water reservoirs are independent of each other and are secured to
the cover of the foot-warmer; they present the form of funnels with orifices at
their lower part. Each of these orifices is closed by a needle acted upon by a
spring which constantly tends to move it downwards. The needle passes with little
friction to the outside through a sleeve bevelled at its upper part, and its head
which can be seized by hand also presents an inclined plane bearing against the
bevel of the sleeve when the orifice in the funnel is closed. By turning the head
of the needle the latter is raised a definite distance owing to the friction of the two
inclined surfaces, which has the effect of uncovering the orifice of the funnel and
thus cause the fall of water upon the lime contained in the apparatus.
For facilitating the removal of the slaked lime I arrange upon the bottom of the
foot-warmer a kind of grate carrying a number of points and provided with two
articulated handles. These handles are turned down upon the sides of the foot-
warmer when the latter is in use; they are brought together in order to take hold
of them more readily when the lime is to be removed. A single reservoir may be
arranged below the cover for obtaining a more intense heat, but in this case the
body of the foot-warmer has no interior partition.
In a modification of my foot-warmer the water is contained in a tube pierced with
holes. This tube is held in a surrounding tube also pierced with holes, opposite
which the first mentioned holes are brought by a turning movement of the interior
tube to cause the outflow of the water contained in the latter.
A somewhat similar arrangement comprises two systems of tubes and is divided

page_text: into two compartments. The two parts of the apparatus may operate successively,
thereby doubling the length of the heating.

COMPLETE SPECIFICATION.
Improvements in and relating to Foot-warmers and the like.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, 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:-
The present invention relates to foot-warmers and the like, and has for its object
to provide for expeditiously heating the same.
This heating is effected rapidly and at the desired moment by the projection of a
certain volume of water contained in a part of the foot-warmer upon a propor-
tionate volume of lime previously introduced at the bottom of the said foot-
warmer.
In order to render my system better understood I have represented it on the
accompanying drawing as applied to a foot-warmer.
In the drawings,
Figure 1 is a longitudinal vertical section of the stove.
Figure 2 a transverse section and,
Figure 3 a plan thereof.
The improved apparatus comprises one or more water reservoirs placed at one of
the extremities of the foot-warmer. These reservoirs terminate in a point and
present at this point a hole of small diameter which may be opened by means of a
needle valve operated by a spring which permits the flow of the water into the
several compartments of the foot-warmer.
Figures 1, and 3 represent a foot-warmer with two compartments and with two
water reservoirs at the upper part of the foot-warmer, each of these reservoirs being
arranged at the top of a compartment in the body of the foot-warmer, with the
object of ensuring a longer duration in the operation of the apparatus.
The body A of the foot-warmer contains a suitable quantity of lime; it is divided
into two compartments separated by a partition X and is closed by a cover B
having a packing of hollow indiarubber. This cover B is held on the one hand
by means of a hook a extending below a cap or link b, and on the other hand by
means of a stop c jointed to the cover and the upper extremity of which engages
with a stud d on the body of the foot-warmer.
The aforesaid water reservoirs D are independent of each other and are secured
to the cover B of the foot-warmer; they are made funnel shaped and are pro-
vided with orifices d' at their lower part. Each of these orifices is closed by a
needle e acted upon by a spring which constantly tends to move it downwards.
The needle passes with little friction to the outside through a sleeve g bevelled at
its upper part and its head which is shaped so as to be conveniently seized by hand
presents an inclined plane bearing against the bevel of the sleeve g when the orifice
in the funnel is closed. By turning the head of the needle the latter is raised
a definite distance owing to the action of the two inclined surfaces, which has
the effect of opening the orifice d of the funnel and thus causing the fall of water
upon the lime contained in the apparatus.
For facilitating the removal of the slaked lime I arrange upon the bottom of
the foot-warmer a grate E carrying a number of points and provided with two
jointed handles F. These handles are turned down upon the sides of the foot-
warmer when the latter is in use; they are however brought together in order to

reservoir may be arranged below the cover for obtaining a more intense heat, but
in this case the body of the foot-warmer has no interior partition.
Figures 4, 5 and represent a modification of my invention the water being
contained in a tube G pierced with holes, k. This tube G is held in an outer
tube H also pierced with holes opposite to which the first mentioned holes are
brought by giving the interior tube Ġ a partial turn so as to permit the outflow
of the water contained in the latter.
Figures 7 and 8 show a somewhat similar arrangement to that represented in
Figures 4 to 6, but it comprises two systems of tubes G H, G₁ H¹ and it is
divided into two compartments A. A'. The two parts of the apparatus may
operate successively thereby doubling the length of time during which heat is
given out.
I may vary the shape, materials of construction and dimensions of my foot-
warmer, and also the number of compartments therein, without departing from
the spirit of my invention.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed as communicated to me by
my foreign correspondent, I declare that what 1 claim is :-
My improved foot-warmer consisting essentially of the arrangement of either
one or more reservoirs situated above one or more compartments the said reser-
voirs being provided with obturating needle valves regulating the outflow of the
water upon a mass of lime placed in each of the compartments, and one or more
tubes pierced with holes the outflow of the water being determined by the rotation
of these tubes, so rotated for the purpose of bringing the holes in the said tubes
opposite holes of the same diameter pierced in sheaths which surround them and
separate them from the compartment or compartments containing the lime.
