PROVISIONAL SPECIFICATION.
Improvements in or Appertaining to Alarums or Alarms.
We WILLIAM HOLMES, of Fernbank Street Green Lane, Warp Dresser, and
JOSEPH HOLMES, of John Street, Wood-bottom, Spinning Overlooker, both of Baildon,
in the County of York, do hereby declare the nature of this invention for IMPROVE-
MENTS IN OR APPERTAINING TO ALARUMS OR ALARMS, to be as follows:-
This invention relates to improvements in or appertaining to alarums or alarms
particularly applicable for domestic use; and its object is to provide a simple and
efficient apparatus capable of being set or arranged to produce a continuous noise at a
specified time.
For this purpose in connection with a suitable timepiece we employ a small boiler
fitted over a gas stove. The said stove is supplied witli gas from a pipe provided with
a valve operated by mechanism in connection with the said timepiece. A small
lighting burner supplied by an independent pipe and controlled by a separate valve is
fitted over the stove. A steam whistle is connected to the top of the said boiler, and
such boiler is provide with a suitable orifice or mouth by which it is filled. A safety
valve of ordinary construction may also be fitted to the boiler. Such safety valve
may consist of a weighted valve closing the orifice by which the boiler is filled.
The apparatus is used as follows: The said timepiece is so constructed that it can
be arranged to open the valve admitting gas to the stove approximately at the time
it is desired the alarm should sound. The timepiece having been set to operate the
gas valve by the mechanism connected thereto at the specified time, the boiler is
supplied with water, and the small lighting jet is lit. The moment the timepiece
opens the gas valve the gas thereby supplied to the stove is ignited by the lighting
jet; thus heating the boiler to boiling point, when the steam developed issues from
and blows the whistle at the top of the boiler until the stove is turned out. The said
boiler is provided with a suitable valve enabling the heated water to be withdrawn for
domestic use.

page_text: We, WILLIAM HOLMES, of Fernbank Street, Green Lane, Baildon, in the County
of York, Warp Dresser, and JOSEPH HOLMES, of John Street, Wood Bottom, of Baildon
aforesaid, Spinning Overlooker, do hereby declare the nature 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 improvements in or appertaining to alarums or alarms
particularly applicable for domestic use, and its object is to provide a simple and
efficient apparatus capable of being set or arranged to produce a continuous noise at
a specified time.
The said apparatus consists of a boiler provided with a steam whistle and mounted
over a gas burner or stove, which is arranged in connection with a suitable time-
piece in such a manner that at any desired time such stove is automatically lit or
the light therein sufficiently increased to boil the water in the said boiler, thus
generating steam which blows the said whistle and gives an audible alarm.
In order to fully describe our invention reference is to be had to the accompanying
drawing forming a part of this specification, in which similar letters of reference
indicate corresponding parts in both the figures.
Figure 1 represents an elevation of our improved apparatus, and Figure 2 is a plan
of the same.
The time piece A is provided with an ordinary alarm attachment, the bell and
hammer of which may be dispensed with. The arbor B on which the spring actuating
the said alarm attachment is mounted is provided with a lever C connected by a rod D
to the lever E secured to the plug of the valve or tap F in the gas pipe G supplying
the stove H with gas. A small lighting jet I carried by the pipe J branching from G
above the tap F extends to the burner K of the stove H, the supply of gas to which
as well as to the pipe G is controlled by the valve or tap L. The boiler M. mounted
on the stove H is provided with a steam whistle N and also with a screw lid O and
a valve or tap P for withdrawing the contents.
The apparatus is used in the following manner. The alarm attachment of the time-
piece A being set to "go off" at the required time turns the arbor B to the position
shown, when the boiler M is filled with water, the tap L turned on and the fighting
jet 1 is lit.
At the specified time the alarm mechanism is operated by the timepiece
and the arbor B turns the lever C to the position indicated by the dotted representa-
tion in figure 1 and also turns the lever E thereby opening the tap F supplying gas
to the burner K of the stove H which is immediately lit by the lighting jet I. In a
few minutes the heat from the stove boils the water in the boiler M. and the steam
generated issues from the whistle N thus making a continuous alarm. The alarm is
stopped by closing the tap L to cut off the supply of gas. And the boiling water
may be withdrawn by the tap P for domestic use.

page_text: A safety valve may be fitted to the boiler if desired but, if the gas burner is not
too large in proportion to the boiler it will be found that the whistle carries off
the steam without causing undue pressure in the boiler.
It is obvious that the valve supplying gas to the stove may be operated by a
timepiece in various other ways, but we find the arrangement described satisfactory.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare what we
claim is:
1. The arrangement and combination of a boiler provided with a steam whistle, of
a gas stove or heating apparatus, and a timepiece adapted to automatically light said
stove or heating apparatus, substantially as herein shown and described and for the
purpose specified.
2. The arrangement and combination with a boiler provided with a steam whistle
and fitted with a tap or valve adapted to withdraw the contents thereof, of a gas stove
or heating apparatus, and a timepiece arrange to automatically light said stove or
heating apparatus, substantially as herein shown and described.
