PROVISIONAL SPECIFICATION.
Improvements in or relating to Automatic Sprinklers or Fire
Extinguishers.
I JAMES HENRY LYNDE, of 17 Cooper Street, Manchester in the County of
Lancaster, Civil Engineer, do hereby declare the nature of said Invention for
IMPROVEMENTS IN OR RELATING TO AUTOMATIC SPRINKLERS OR FIRE EXTINGUISHERS
to be as follows:-
The object of my Invention is to render automatic fire extinguishers commonly
called sprinklers more reliable and more sensitive to the action of heat.
To effect this I construct the body of the sprinkler of metal in two (or more) parts
and between the two parts I interpose a union, ferrule, bush, ring, washer, or other
part or parts of vulcanite, ebonite, compressed paper or cotton, wood, or other suitable
non-conducting material so as to divide the upper metal portion which is or may he
attached to the water pipe from the lower metal portion which carries or may carry
the seal or joint of sensitive solder; or I insert between the water pipe and a sprinkler
of any form a union or other part of vulcanite or other suitable non-conducting
material as above mentioned so as to separate the metal connection between the metal
water pipe and the metal sprinkler, or I construct the body of the sprinkler wholly
or partly of compressed paper or cotton or other suitable non-conducting material as
previously indicated.
By these means I am enabled to prevent the rapid conduction to the water pipes of
the heat which has been absorbed by the metal parts of the sprinkler and thus the heat
accumulates where it is required and causes the temperature of the metal parts, in
contact with the solder seal or joint, to rise more rapidly and render the apparatus
more sensitive to the action of heat than would otherwise be the case.
Sprinklers of any existing construction may by my Invention be rendered more
sensitive by simply interposing a part or parts of non-conducting material between
such sprinkler and the water pipe.

Improvements in or relating to Automatic Sprinklers or Fire
Extinguishers.
I JAMES HENRY LYNDE, of 17 Cooper Street, Manchester, in the County of
Lancaster, Civil Engineer, do hereby declare the nature of said Invention for
IMPROVEMENTS IN OR RELATING TO AUTOMATIC SPRINKLERS OR FIRE EXTINGUISHERS,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The object of my Invention is to render automatic fire extinguishers commonly
called sprinklers more reliable and more sensitive to the action of heat.
To effect this I construct the body of the sprinkler of metal in two (or more) parts
and between the two parts I interpose a union ferrule bush ring washer or other part
or parts of vulcanite ebonite compressed paper or coiton wood or other suitable
non-conducting material so as to divide the upper metal portion which is or may he
attached to the water pipe from the lower metal portion which carries or may carry
the scal or joint of sensitive solder; or I insert between the water pipe and a sprinkler
of any form a union or other part of vulcanite or other suitable non-conducting
material as above mentioned so as to separate the metal connection between the metal
water pipe and the metal sprinkler.
By these means I am enabled to prevent the rapid conduction to the water pipes
of the heat which has been absorbed by the metal parts of the sprinkler and thus the
heat accumulates where it is required and causes the temperature of the metal parts
in contact with and adjacent to the solder seal or joint to rise more rapidly and render
the apparatus more sensitive to the action of heat than would otherwise be the case.
Sprinklers of any existing construction may by my Invention be rendered more
sensitive by simply interposing a part or parts of non-conducting material between
such a sprinkler and the water pipe.
It will be understood that by the words "non-conducting material" I mean a
material of a low conducting power for heat such as hereinbefore mentioned.
Some modes in which my Invention may be applied are illustrated in the accom-
panying Drawings.
Fig. 1 represents a section of a sprinkler the metal body of which is separated into
two parts a and a' by the interposition of a non-conducting threaded nipple and a
non-conducting washer I'.
Fig. 2 represents a section of a sprinkler the metal body of which is separated into
two parts a and a¹ by the non-conducting double threaded flanged bush or union h.
Fig. 3 represents, a section of a sprinkler the metal body of which is separated into
two parts, a and a¹ by the non-conducting double threaded bush or union h.
Fig. 4 represents a section of a sprinkler attached to a water pipe by means of a
non-conducting threaded nipple or union-h.

page_text: My invention may obviously be applied in other ways but care should in all cases
be taken to completely separate the metallic portions by the non-conducting material.
For each case illustrated the seal of sensitive solder is situate at the lower part
of the sprinkler at s. The heat absorbed is retained in the sprinkler any loss by
conduction into the water pipes being prevented by the non-conducting nipples
unions or bushes and washers h¹.
I have in the Drawings shown the sprinklers with a protecting substance as
described in my Specification No. 7226 of even date herewith but this forms no part
of my present Invention.
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. An automatic sprinkler having the body thereof constructed in parts which are
united by a threaded nipple or other threaded piece such as a union ferrule ring
washer or other part or parts of non-conducting material or material of low
conductivity substantially as and for the purposes described.
2. The use and application of a nipple union ferrule ring washer or other part of
non-conducting material or material of low conductivity as the means for connecting
a sprinkler to its water supply pipe and for preventing any metallic contact between
the said sprinkler and pipe substantially as described.
3. The combination consisting of an automatic sprinkler of the sealed type united
to a pipe for the supply of water by means of a non-conducting substance in the
manner and for the purposes hereinbefore described.
4. The several constructions embodying my improvements in automatic sprinklers
substantially as herein described with reference to Figs. 1, 2, 3 and 4 of the Drawings
annexed.
