page_text: I, LIONEL SIMONS, of Holly Lodge, Bromley, in the County of Kent, Gentlo-
man, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved bed-warmer, the object of the invention
being to provide apparatus whereby a bed can be warmed over a much larger
area than is possible with such apparatus as now generally made, the said
apparatus being, however, so constructed that when not required for use it can
be collapsed or folded so that it can be stored in a small space.
In carrying out my invention I construct the bed-warmer of a number of
tubes or pipes connected together trellis-like or on the principle of the lazy
tongs so that they can be collapsed to occupy a small space when not required
for use or opened out so as to cover practically the length of the bed. The
tubes or pipes are all in communication with one another so that hot water can
be poured in at one end of the apparatus and air allowed to escape at the other.
Or I can fill the pipes with water by means of a suitable syphon arrangement.
To prevent the pipes giving up the heat of the water too readily I may make
them of a material which is not a very good conductor of heat and the apparatus
may be provided with one or more non-conducting chambers or reservoirs for
the water.
The apparatus instead of being arranged to retain water can be filled with a
suitable heat absorbing material which may be heated to the required tem-
perature by running water through the pipes or by other suitable means.

I, LIONEL SIMONS, of Holly Lodge, Bromley, in the County of Kent, Gentle-
man, 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:-
This invention relates to an improved bed-warmer, the object being to provide
apparatus whereby a bed can be warmed over a much larger area than is possible

page_text: with such apparatus as now generally made, the said apparatus being, however,
so constructed that when not required for use it can be collapsed or folded so
that it can be stored in a small space.
In carrying out my invention I construct the bed-warmer of a number of
tubes or pipes connected together trellis-like or on the principle of the lazy
tongs so that they can be collapsed to occupy a small space when not required
for use or opened out so as to cover practically the length of the bed. The
tubes or pipes are all in communication with one another so that hot water can
be poured in at one end of the apparatus and air allowed to escape at the other.
Or I can fill the pipes with water by means of a suitable syphon arrangement.
To prevent the pipes giving up the heat of the water too readily I
may make
them of a material which is not a very good conductor of heat and the apparatus
may be provided with one or more non-conducting chambers or reservoirs for
the water.
The apparatus instead of being arranged to retain water can be filled with a
suitable heat absorbing material which may be heated to the required tem-
perature by running water through the pipes or by other suitable means.
To enable the invention to be fully understood I will describe it by reference
to the accompanying drawing, in which:-
Figure 1 is a side elevation of a bed warmer made according to the invention
and shewing the same in its collapsed or folded up position:
Figure 2 is a side elevation of the apparatus shewing it extended for use.
Figure 3 is a plan of the collapsed apparatus:
Figure 4 is a view similar to Figure 3 but shewing the two uppermost tubes
or pipes cut away to illustrate the method of hinging the pipes together at the
centre:
Figures 5, 6 and 7 are views of details drawn to a larger scale.
a, a are the tubes or pipes, which are hinged together as shewn at a¹ at their
ends and at a² at their centre on the principle of the lazy tongs as herein before
mentioned so that they can be collapsed as illustrated in Figures 1, 3 and 4
when not required for use or expanded or opened out as illustrated in Figure 2
so as to cover practically the whole length of the bed.
In the drawing I have illustrated a form of my bed warmer wherein the heat
is obtained by means of hot water which is filled into the tubes. To this end
the tubes must all be connected together by suitable watertight joints and the
joint which I advantageously employ is represented in Figure 5. It is formed
of a pin b which passes through the two tubes a, a to be connected and is
soldered or otherwise suitably fixed to one of the said tubes, the other end pro-
jecting through the other tube a and being tapped to receive a screw c. To
facilitate the turning of the upper tube a (Figure 5) upon the pin b, the said
upper tube is provided with a bush d which passes through the tube around
the pin 6 so as to form a bearing and is formed on its two projecting ends with
flanges d¹, d. e, e are rubber washers which are provided between the head of
the bolt c and the flange d on the one hand and the flange d¹ and a corresponding
flange on the pin 6 between the two tubes a, a on the other hand so as to
form watertight joints. The pin b is made hollow throughout the greater part
of its length as indicated at f and is also provided with two orifices 9, 9 which
place the inside of each tube a in connection with the hollow portion f thus
placing each two connected tubes a, a in communication with one another.
The joints as are formed by means of the device illustrated in Figures 6 and 7.
This device comprises a couple of plates h, h which are bent to correspond to
the shape of the tubes a, a and are soldered thereto and are pivoted together
by means of a pin i in such a manner that they can move relatively with one
another thereby allowing the tubes a, a which are soldered thereto to also turn
relatively with one another.
To enable the apparatus to be filled with water, the two tubes at one end are
provided with screw plugs j, j so that by removing these two plugs the apparatus

page_text: can be filled with water and the plugs replaced, when the apparatus will be
ready for use.
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. A bed-warmer comprising a number of tubes hinged together on the prin-
ciple of the lazy tongs and designed to receive a suitable material such as hot
water or a suitable heat absorbing material, substantially as herein before
described.
2. The combination and arrangement of parts forming the improved bed-warmer
herein before described and illustrated in the accompanying drawing.
