Complete Specification Left, 25th July, 1899-Accepted, 16th Sept., 1899
I, JOSEPH ROWLEY, of 4, Edgewell Villa, Church Road, Flixton, in the County
of Lancaster, Ironfounder, do hereby declare the nature of this invention to be
as follows: -
This invention relates to means for storing power whereby air, water, or other
fluid may be utilized under pressure either occasionally or for a lengthened
period.
In this invention I construct a case or shell preferably cylindrical with a cover
plate fitted at the top and at the bottom of said shell, so as to obtain an air tight
receptacle.
I place within the aforesaid case one or more cylinders which may be con-
tained one within the other, each of a smaller diameter and shorter than the
outer case, with closed tops, so that a space may be left around and at the top
between the inner cylinder or cylinders and the outer cylinder. I place a vertical
air pipe within the aforesaid cylinder reaching to within a short distance of the
top of the inner cylinder and fitted with a back pressure valve.
The lower end of said pipe is carried through the bottom flange and connected
to a force pump; I fit a pipe to the bottom flange for the supply or delivery of
water to or from the cylinder, and a pressure gauge for indicating the force
contained in the cylinder. I fit a safety valve to the top cover, also a vent plug
and an inlet pipe for occasional use, a cap being placed over the said inlet and
bolted or otherwise secured to the cover. Fusible plugs may be fitted at the top
and bottom of the cylinder or in other convenient positions.
In applying my invention, the cylider is either filled with air and water, then
forced in, or water is let into the cylinder until the inner cylinder is filled to
within about a fourth of its height; air is then forced in through the aforesaid
vertical air pipe. If water has been let into the cylinder the level of the water in
the inner cylinder is reduced but in either case the spaces around the outside of
the inner cylinder and between the inner and outer cylinders are completely filled.
The air that is forced into the central cylinder is compressed and retained under
pressure until the air or the water is required to be utilized either for working a
machine or other purpose or by the fusion of a plug or plugs in case of fire, for
the water to be ejected as in a sprinkler.

page_text: An Improved Hydraulic or Pneumatic Accumulator.
I, JOSEPH ROWLEY, of 4, Edgewell Villa, Church Road, Flixton, in the County
of Lancaster, Ironfounder, do hereby declare the nature of 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 improved means for storing power whereby air,
water, or other fluid may be utilized under reserved pressure either occasionally
or for a lengthened period.
In the accompanying drawing, Fig. 1 is a side elevation and Fig. 2 a vertical
section of an apparatus constructed according to my invention.
I provide a case or shell as a, preferably cylindrical, with flanges at each end
as a and a²; a cover plate b which may be formed with feet or supports 6*, and
with an inner circular flange c, is bolted to the bottom flange a and a cover
plate 6 is bolted to the top flange a² of the cylinder. I place within the said
cylinder, a cylinder as d that is of smaller diameter and preferably shorter
internally than the outer case so that a space e is left around and at the top
between the inner and outer cylinders; apertures as d¹ are formed around the
base and the extended portion at the top of said inner cylinder which is retained
in a central position by the edge of the bottom or open end fitting on or
within the flange c, and the closed upper end d², being supported by an open
ring for other equivalent device; I place a pipe as g, within the aforesaid inner
cylinder, and pass the lower end of said pipe through the bottom cover 6 to
which it is secured, and connected with an air pump; the upper end of the pipe g
is provided with a back pressure valve g¹. I fit a safety valve such as k and a
pressure gauge to the cover b¹ or in other preferred position and cocks or taps
as m and that may be opened occasionally if required by an attendant when
charging the cylinder.
For the purpose of utilizing the stored power for ejecting water in the event
of an outbreak of fire during the absence of the persons occupying or using a
building, I fit either fusible plugs or any preferred form of sprinklers to the
top or side of the cylinder, or placed around the cylinder as at q which when the
fusible metal is melted, the stored pressure will cause the water or other fluid
contained in the cylinder to be sprayed on to the fire.
In applying my invention water or other fluid is pumped or caused to enter
at p and any air that may be within the space e is let out through the cock m
until the whole of the space e is filled with fluid and the inner cylinder d to
about one fourth of its height, when the cock m is closed. Air is then forced
in to the inner cylinder d through the pipe 9 until the pressure required is
recorded by the gauge 1. When the power thus stored is to be applied a pipe is
connected to the outlet t and utilized as required for transmitting motion to
machinery or for other purposes.
The height of the water in the inner cylinder d can be noted by a float or by
a gauge glass that may be fitted on the outside of the cylinder a.
When pre-
ferred two or more cylinders as d may be employed, contained one within the
other. If occasionally the pressure in the air cylinder is required to be reduced
the cock v may be opened.
.
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 accumulator for the storage of power for use in driving machinery or

page_text: other purpose that is constructed by means of an outer cylinder as a and one or
more inner cylinders as d that are closed at the top and open at the bottom,
said inner cylinder or cylinders being of smaller diameter and preferably shorter
internally than the outer cylinder so that a space may be left around and between
said outer and inner cylinders, a pipe extending from the outside of the bottom of
the outer cylinder to within a short distance of the roof of the inner cylinder or
cylinders and fitted with a back pressure valve, by which air may be
forced into the said inner cylinder or cylinders, an inlet for the
supply of water or fluid to said outer and inner cylinders, and an outlet by which
said stored power may be utilized, all substantially as herein before described.
2. An accumulator for the storage of power that is constructed as herein before
described and fitted with fusible plugs or with any preferred form of sprinklers
by which in case of fire, water or other fluid may be caused to be sprayed.
