IMPROVEMENTS IN PORTABLE PUMPS OR ENGINES FOR EXTINGUISHING FIRES. AND OTHER PURPOSES
Year: 1861

page_text: LETTERS PATENT to Joseph Hall, of Oldham, in the County of Lancaster,
Engineer, for the Invention of "IMPROVEMENTS IN PORTABLE PUMPS OR
ENGINES FOR EXTINGUISHING FIRES. AND OTHER PURPOSES."
Sealed the 25th February 1862, and dated the 2nd September 1861.
PROVISIONAL SPECIFICATION left by the said Joseph Hall at the
Office of the Commissioners of Patents, with his Petition, on the 2nd
September 1861.
I, JOSEPH HALL, of Oldham, in the County of Lancaster, Engineer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PORTABLE PUMPS OR ENGINES FOR EXTINGUISHING FIRES, AND OTHER PURPOSES,"
to be as follows:-
My Invention relates to an improved construction and arrangement of
portable pumps or engines, and consists in forming the bed and carriage
(which is mounted on wheels) in one piece, in which the passages for the
water from the suction or inlet to the pumps, and from the pumps to the air
vessel are cast. The clacks in the pumps and air vessel are secured to facings
on the bed, and the inlet and outlet orifices are arranged above the level of
the passages in the bed. The two pumps are actuated by a beam lever fixed
on a shaft carried by two brackets, one secured on each side of the bed, and
this shaft is worked by a beam lever with folding handles. The lift of the
pumps or extent of oscillation of the beam lever is determined by stops formed
by projections from the side brackets carrying the shaft.

by the said Joseph Hall in the Great Seal Patent Office on the 1st
March 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPп
HALL, of Oldham, in the County of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second September, One thousand eight hundred
and sixty-one, in the twenty-fifth year of Her reign, did, for Herself, Her
heirs and successors, give and grant unto me, the said Joseph Hall, Her
special license that I, the said Joseph Hall, my executors, administrators,
and assigns, or such others as I, tho said Joseph Hall, my executors,
administrators, 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 PORTABLE PUMPS
OR ENGINES FOR EXTINGUISHING FIRES AND OTHER PURPOSES," upon the condition
(amongst others) that I, the said Joseph Hall, by an instrument in writing
under my hand and seal, 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 Joseph Hall, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement and accompanying Drawings (that is to say) :-
My Invention relates to an improved construction and arrangement of
portable pumps and engines, and consists in forming the bed and carriage
(which is mounted on wheels) in one piece, in which are cast passages for water
from the suction or inlet to the pumps, and from the pumps to the air vessel.
The clacks in the pumps and air vessel are secured to facings on the bed,
and the inlet and outlet orifices are arranged above the level of the passages
in the bed. The two pumps are actuated by a beam lever fixed on a shaft
carried by two brackets or standards, one secured on each side of the bed,
and this shaft is worked by a beam lever with folding handles. The "lift" of
the pumps or extent of the oscillation of the beam lever is determined by stops
formed by projections from the side brackets carrying the shaft.

page_text: Fig. 1 is a plan view, the lever handle being shown in the horizontal
position; Fig. 2, a side elevation, the lever handle being shown down to its
lowest position on one side. a is the bed cast in one piece, and in which the
water passages (a¹) are formed. This bed is mounted on two hind wheels and
one fore wheel, the latter being made to swivel, an handle (6) by which the
wheel is guided, being jointed with its axis. The bed has also two cavities
formed in its upper side covered with hinged lids (a,) which are intended as
receptacles for keys and other articles connected with the engine. On each
side of the bed a side standard (c) is bolted in which bearings are formed for
a shaft d, to the ends of which the lever handle or frame e is secured; each
standard carries two studs (c') which limit the extent of oscillation in the
lever frame (e). The shaft (d) has a beam lever d¹ keyed upon it, which
gives motion through connecting links (d2) to the piston rods (ds) of the
pumps working through guides (d') attached to the upper flange of the
cylinder (f) of each pump; these pump cylinders are bolted down upon
the bed, the clacks and pistons being of ordinary construction. The air
vessel (9) is also bolted to the bed; a part (n) forming the inlet orifice is also
secured to the bed. The outlet is from a branch (f) from the air vessel at the
same level above the bed as the inlet orifice (n). The lever handles (e) are
jointed so that they can be turned back out of the way, when not in use, into
the position shewn in dotted line in Fig. 2, and are held in the extended
position when in use by means of studs (e¹) and sliding hoops (2.)
I have now particularly described the nature of my Invention, and mode of
carrying the same into effect, and wish it to be understood that I claim the
construction of the bed and carriage frame of portable pumps or engines, and
the combination and arrangement of the parts, substantially in the manner
herein-before described.
In witness whereof, I, the said Joseph Hall, have hereunto set my
hand and seal, this Twenty-eighth day of February, in the year of our
Lord One thousand eight hundred and sixty-two.
JOSEPH HALL. (L.S.)
