BENJAMIN JOSEPH BARNARD MILLS of the Firm of Harris and Mills of
23 Southampton Buildings in the County of Middlesex Patent Agent. IMPROVE-
MENTS IN APPARATUS FOR HEATING WATER." A communication from abroad
by Louis Julien Robin, Senior of Paris in the Republic of France.
The new arrangement forming the subject of the present application consists of
a portable apparatus capable of being applied at any desired place to a water
supply pipe for instantly beating the water at any pressure, enabling this hot
water to distributed with the same cock or valvo gear employed for distributing
the cold water of the said pipes.
The various applications of which the improved arrangement of boiler is capable
for supplying hot water to baths, dressing rooms, laundries and various other
purposes will readily be suggested, the apparatus being capable of ready transport
to the various receptacles in which the hot water is to be employed.
The fuel it is preferred to employ in this apparatus is gas, but the heat required
for the same may be obtained by means of combustible liquids or even by coal or
coke.
The apparatus according to circumstances can be made of copper sheet iron or
other suitable metal or material; it is constructed in such manner that the
expenditure of the fuel is very small, so as to realize at the same time a convenient,
simple and economic system.
These advantages will be fully set forth and understood by reference to tho
accompanying Drawings in which an example of the apparatus is represented.
Figure 1 represents the said apparatus in elevation showing an exterior view and
the small inconvenience resulting from its application. Figure 2 is a vertical
section through the centre thereof. The entire apparatus is mounted on a dish
shaped foot or base a intended to receive the water of condensation which would
be formed in the apparatus. On this baso is soldered or fixed in any other
convenient manner a tube b which receives any suitable number of burners c the

page_text: outer end of each of which is closed by a screw stopper d serving to permit of the
cleaning of the burners.
The tube b.carries at its upper end a ring or handle c which is fixed to it and
is used for carrying the apparatus when it is required to remove it.
To the lower part of the tube b is fixed a perforated plate f which supports the
moveable metallic case g.
The air necessary for combustion enters the apparatus by the perforations h of
the plate and the case g is intended to prevent radiation in order to avoid all
loss of heat.
A smoke consumer i mounted at the upper part of the combustion chamber
formed by the case g enables the gases of combustion to be burnt, which causes
the apparatus to give off no odour and not the slightest inconvenience can result
from its application.
There cannot be produced any danger of explosion in the apparatus (when gas is
employed as the fuel) provided that a space is arranged between the upper part of
the case and the smoke consumer i. However for greater safety there is provided
at the upper part of this smoke consumer a moveable cover which is capable of
sliding freely upon the tube b if the pressure should be raised in the apparatus.
This cover is represented in its most elevated position by dotted lines in
Figure 2.
The apparatus thus arranged works in the following manner; to one of the
cocks of the service pipe or to a cock placed in any position is adapted a flexible
tube which is fixed on the tube connected with the apparatus to which it is fixed
in any convenient manner and position.
At the lower part of the apparatus this tube is sub-divided into a number of
small tubes.m sufficiently flexible to be coiled and make one or several turns
above the burners c.
For greater clearness in the Drawings the coils are represented in section in
Figure 2 above the lower burner.
These coils in which the water of the service pipe circulates and retains all its
pressure, after rising to the upper part of the apparatus, re-descend vertically and
are then united in an outlet tube n similar to the inlet tube and which is
connected in the same manner with the receiver for the hot water.
The heating surface increased in this manner produces instantaneously very hot
water in the outlet tube n without lowering its pressure.
The casing is so arranged as to be readily removeable to permit of the cleaning
of the burners c which can be effected by introducing into them a small hard
brush after having removed the screw stoppers d.
It should be understood that the arrangement and general dimensions of the
apparatus as also the number, and the quantity of turns, of the coils may be varied
according to circumstances or the degree of heat it is desired to give to the water
circulating in the apparatus.
