Improvements in Hand
arming Aррпа ces.
I, The Right Honourable DOUGLAS MACKINNON BAILLIE HAMILTON COCHRANE,
EARL OF DUNDONALD, of 34 Portman Square, in the County of London, do hereby
declare the nature of this invention to be as follows:-
In my Specification No. 5841 of 1896 I have described a pocket stove com-
prising a casing into which is introduced a charge of slow burning fuel, the air
necessary for combustion and the gaseous products of combustion passing through
perforations of the casing which are shielded by internal pervious and incom-
bustible screens so as to prevent issue of dust and ash. My present invention
relates to modifications of stoves of the kind above referred to so as to adapt them
to act as hand warming appliances:
For a stove to be held in the hand I make the case cylindrical or approximately
cylindrical or fluted, throughout the greater part of its length preferably swelling
it to a larger diameter at each or either end so that it can be conveniently grasped
in the hand. I line the whole interior with the pervious screen preferably leaving
a little space around the screen between it and the case for distribution of the

different form without the swelling at both ends can be adapted as a landle for
various articles for example as the steering handle of a velocipede or motor car.
the handle of a whip, or of a walking stick, umbrella or the like. For the steering
handle of a. velocipede which is usually tubular, the warming appliance may be
made as an extension of the handle, one part of its length being of such diameter
that it can be inserted into the tube of the handle, and secured by a screw or
bayonet catch, the other part extending beyond the handle so that the hand of
the rider may be applied to the ordinary handle or to its heated extension at
pleasure.
Dotad this 11th day of November 1896.

page_text: 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:-
In my Specification No. 5841 of 1896 I have described a pocket stove com-
prising a casing into which is introduced a charge of slow burning fuel, the air
necessary for combustion and the gaseous products of combustion passing through
perforations of the casing which are shielded by internal pervious and incom-
bustible screens so as to prevent issue of dust and ash. My present invention
relates to modifications of stoves of the kind above referred to so as to adapt them
to act as hand warming appliances which can be applied to the steering handles
of velocipedes or motor cars to the handles of whips sticks or umbrellas or can be
used by themselves without being attached to any handle.
Figure 1 of the accompanying drawings is a side view partly in section of a
steering handle of a velocipede or motor car with a stové according to my inven-
tion applied thereto. Figure 2 is a transverse section on the line 2, 2.
Figure 3
shews a modification of the stove shewn in Figure 1. Figure 4 shows a stove
applied to a whip handle. Figure 5 is a transverse section on the line 5-5.
Referring first to Figures 1 and 2, the warmer consists of a metallic case, one
part A of the length of which is of such diameter that it can be slid into the end
of the tubular steering handle which is usually covered with some non metallic
material C. The other part B of the warmer is made of larger diameter so that
the hand can readily be moved from C to B or the reverse. This large part of
the casing which preferably tapers to a larger diameter at the outer end as shewn
is perforated with numerous holes for admitting air to support the combustion
of the fuel F within the casing, and for allowing escape of the gaseous products
of combustion. Within the enlarged part of the casing there is fixed a cylindrical
screen D of wire gauze or perforated metal, and outside this screen between it
and the casing B there is fixed another screen E consisting preferably of two
shells of perforated metal or wire gauze having between them a fabric such as
muslin rendered incombustible. The screens D and E while they permit passage
of air and gaseous products of combustion prevent ashes and dust resulting from
combustion of the fuel F from issuing through the holes of the casing. For
introducing the fuel there is an opening at the end covered by a screw cap G
having preferably in front of it, a dome H. of perforated metal or wire gauze against
which the fuel can rest.
Instead of having the hole and cap G at the outer end it may be at the inner
end of the tube A as shewn at G in Fig. 3, the enlarged part B of the casing
being of pear shape and the screen E being approximately of similar shape.
The warmer may be secured in the tube of the handle by a screw K as shewn
or for this a bayonet joint or spring catch might be substituted.
When the part A is of sufficient size to accommodate screens such as D and E
as well as the fuel, that part may be perforated and the screens extended along it.
For applying the warmer to a handle such as that of a whip which is not
tubular, I construct it as shewn in Fig. 4 with a projecting socket L which is
split so that it can be sprung on the stem or handle N.
The casing B may be made with corrugations or furrows as shewn in Figs. 4
and 5 the holes being made preferably through the sides of the grooves.
A convenient form of hand warmer for use by itself can be constructed by
making the end part A of the warmer shewn in Figs. 1 and 3 of a suitable size
to fit into the socket of the warmer shewn in Fig. 4 so as to form a warmer of
dumb bell shape or configuration. Or instead of constructing such a dumb bell
shaped warmer of two parts each having a separate combustion chamber, it may
be made in one piece with a single combustion chamber, into which can be inserted
a rod of fuel which may be ignited at either or both ends.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that I make no general
claim to a handle heated by the slow combustion of fuel within it, but only such a
handle as has interposed between the fuel and the perforated portions of the shell
a pervious screen such as is herein before described but what I claim is:
1. A hand warming appliance consisting of a perforated metallic case having
within it a rod of suitable fuel separated from the case by pervious screens, having
also a hole and cap for introduction of the fuel and an extension of the case
adapted to enter the interior of a tubular handle, substantially as described.
2. A hand warming appliance such as is above referred to and having a split
socket adapted to hold a whip or other stem or handle, substantially as described.
