page_text: ¨ LETTERS PATENT to David Halmshaw, of Halifax, in the County of
York, Machine Maker, for the Invention of "IMPROVEMENTS IN
MEANS OR APPARATUS FOR EXTINGUISHING FIRE IN MILLS, WAREHOUSES,
PUBLIC BUILDINGS, PRIVATE DWELLINGS, STEAM OR OTHER SHIPS, AND LANDING
Sealed the 16th February 1875, and dated the 17th August 1874.
PROVISIONAL SPECIFICATION left by the said David Halmshaw at the
Office of the Commissioners of Patents, with his Petition, on the
17th August 1874.
->
I, DAVID HALmshaw, of Halifax, in the County of York, Machine
Maker, do hereby declare the nature of the said Invention for "Im.
PROVEMENTS IN MEANS OR APPARATUS FOR EXTINGUISHING FIRE IN MILLS, WARE-
HOUSES, PUBLIC BUILDINGS, PRIVATE DWELLINGS, STEAM OR OTHER SHIPS, AND
LANDING STAGES OR OTHER STRUCTURES," to be as follows:-
This Invention relates to apparatus employed for extinguishing fire in
mills, warehouses, and other buildings where perforated pipes are fixed

page_text: under the ceilings, around or otherwise in the rooms for conducting and
ejecting the water thereto.
My improvements consist in applying jets and by preference rose jets
to those pipes instead of the perforations, the said jets being so arranged
as to play or throw one jet against another, so as to distribute the sprays
and thereby to cause the water to spread over the entire room. Each
jet is provided with a stop tap so that any one or more may be shut off,
and the water thus directed to and discharged upon the part of the room
where required. Separate supply pipes are also provided with taps or
valves to the various rooms, and in large rooms two or more supply
pipes are provided, so that the water may be discharged in the room or
part thereof when required. These taps or valves I place in the most
convenient part of the building for access in case of fire.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said David Halmshaw in the Great Seal Patent Office 1
on the 17th February 1875.
-
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
HALMSHAW, of Halifax, in the County of York, Machine Maker, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of August, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said David Halmshaw, Her special licence that I,
the said David Halmshaw, my executors, administrators, and assigns, or
such others as I, the said David Halmshaw, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MEANS
OB APPARATUS FOR EXTINGUISHING FIRE IN MILLS, WAREHOUSES, PUBLIC
BUILDINGS, PRIVATE DWELLINGS, STEAM OR OTHER SHIPS, AND LANDING STAGES OB

page_text: OTHER STRUCTURES," upon the condition (amongst others) that I, the said
David Halmshaw, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said David Halmshaw, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement (that is to say) :-
This Invention relates to apparatus employed for extinguishing fire in
mills, warehouses, and other buildings where perforated pipes are fixed
under the ceilings, around or otherwise in the rooms for conducting and
ejecting the water thereto.
•
My improvements consist in applying jets and by preference rose jets,
being so arranged as to play or throw one jet against another, so as to
distribute the sprays and thereby to cause the water to be spread over
the entire room. Each jet is provided with a stop tap so that any one or
more may be shut off, and the water thus directed to and discharged upon
the part of the room where required. Separate pipes are also provided
with taps or valves to the various rooms, and in large rooms two or more
supply pipes are provided, so that the water may be discharged in the
room or part thereof when required. These taps or valves are placed in
the most convenient part of the building for access in case of fire.
Such being the nature and object of this my said Invention I will
now proceed to describe the same fully, and in order that the con-
struction and action of the apparatus may be fully understood, I have
hereunto annexed a Sheet of Drawings illustrative thereof, in which
Fig. 1 is a side elevation; Fig. 2, a front elevation; and Fig. 3, a back

page_text: distributed (as indicated by dotted lines) in every direction backwards
as well as forwards, the object of the side perforations being to secure
a distribution on and against the internal walls and windows, so as to
prevent the latter being broken and admitting the air. The apparatus
above described is to be attached to water pipes arranged within the
buildings, but the controlling the supply of water is from the outside,
the connecting pipes from outside to the inside pipes being enclosed or
encased so as to preserve them from the action of frost or from damage;
D is a stop tap.
Having thus fully described the nature and particulars of this.my
Invention, I would have it understood that I lay no claim to the rose
jet generally for purposes aforesaid; but what I do claim is, the con-
struction and use of the rose apparatus made and acting or operating in
the new and improved manner herein fully described.
i
In witness whereof, I, the said David Halmshaw, have hereunto ]
set my hand and seal, this Fifteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-five.
Witness,
WALTER BRIERLEY,
Patent Agent,
