I, WILLIAM MCLAREN, of 39, 40 and 41 Moorfields, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to foot-warmers and has for its object to provide in a more
efficient manner than heretofore for the prevention of leakage at the ends of the
same.
In the foot-warmers as ordinarily constructed, the ends consist of recessed or
dished metal plates which are inserted in the body or main portion of the foot-warmer
and are secured therein by means of a piece of metal which is U-shaped in transverse
section and which is bent to the required shape or configuration and placed over the
edges of the dished end and of the body or main portion the whole being then secured
by rivets and made watertight by brazing or soldering. Foot-warmers thus con-
structed are not adapted for the rough handling to which they are generally subjected.
Any jars or shocks which they receive are liable to loosen the soldered parts or crack
the solder and thus cause leakage.
The object of my invention is to obviate this defect and to provide a foot-warmer
which will be much stronger and more durable than those hitherto used.
According to my said invention each of the ends or end-pieces is formed by
stamping or by pressure by means of suitable dies, or is sunk, drawn and blocked in
such a manner that it has a recess or groove adapted to fit the edge of the body or
main portion of the foot-warmer; these ends or end-pieces are fitted upon the body
or main portion and secured by rivets or otherwise without the intervention of a
third piece thus saving cost and labour in the manufacture of the foot-warmner.
In carrying my said invention into practice, I cut a blank of the requisite size and
shape from sheet metal and sink and draw the said blank into the required shape of
the foot-warmer-end, preferably by stamping or by pressure by means of suitable dies.
The said end is thus formed in one piece, having the U-shaped or similar flange
thereon for securing it by means of rivets or otherwise to the body or main portion of
the foot-warmer.

page_text: I, WILLIAM MCLAREN, of 39, 40 and 41 Moorfields, in the County of Middlesex,
Engineer, 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 foot-warmers and has for its object to provide in a more
efficient manner than heretofore for the prevention of leakage at the ends of the
same.
In foot-warmers as ordinarily constructed, the ends consist of recessed or dished
metal plates which are inserted in the body or main portion of the foot-warmer
and are secured therein by means of a piece of metal which is U-shaped in trans-
verse section and which is bent to the required shape or configuration and placed over
the edges of the dished end and of the body or main portion, the whole being then
secured by rivets and made watertight by brazing or soldering. Foot-warmers thus
constructed are not adapted for the rough handling to which they are generally
subjected. Any jars or shocks which they receive are liable to loosen the soldered
parts or crack the solder and thus cause leakage.
My invention is designed to obviate this defect and to provide a foot-warmer which
will be much stronger and more durable than those hitherto used.
According to my said invention each of the ends or end-pieces is formed by
stamping or by pressure by means of suitable dies, or is sunk, drawn and blocked in
such a manner that it has a recess or groove adapted to fit or receive the edge of
the body or main portion of the foot-warmer.; these ends or end-pieces are fitted upon
the body or main portion and secured by rivets or otherwise without the intervention
of a third pieco, thus saving cost and labour in the manufacture of the foot-warmer.
In carrying my said invention into practice, I cut a blank of the requisite size and
shape from sheet metal, and sink and draw the said blank into the required shape of
the foot-warmer-end, preferably by stamping or by pressure by means of suitable
dies. The said end is thus formed in one piece, having the U-shaped or similar flange
or channelled piece thereon for securing it by means of rivets or otherwise to the
body or main portion of the foot-warmer.
In the accompanying drawing,
Figure 1 is a plan of a foot-warmer-end made in accordance with my invention.
Figure 2 is a section on the line x, z, Figure 1.
Figure 3 is a plan, and,

page_text: It will be seen that the foot-warmer-end a has a U-shaped flange or channelled
piece a¹ around it. Into this flange or channelled piece, the extremity of the body
of the foot-warmer is to be placed; the parts are then to be secured by rivets or
otherwise. I thus make at a lower cost than heretofore a tight and very durable
joint between the body and end of the foot-warmer.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it understood
that I claim :-
In or for a foot-warmer, an end-piece formed by stamping or by pressure with a
recess or groove for the reception of the edge of the body of the foot-warmer, sub-
stantially as herein before described.
