Improvements in Apparatus for Producing Hydraulic Water Sprays,
Cascades, and the like.
I EDGAR ALDOUS of 2 Elmhurst Upton Lane, Forest Gate, in the County of Essex,
Engineer, do hereby declare the nature of my invention to be as follows:-
The apparatus according to this invention consists of a case with or without top,
within the case is a lining arranged slightly off the inside of case for the circulation of
water this lining I term "compressive plates." The bottom of the lining has a piece
cut out, round the edge of such opening I attach a dome or roof additionally supported
by a vertical outside tapered tube; through the dome a small end of a tapered pipe is
fixed, slightly projecting under dome, the upper part of the pipe is secured to the top
of the tapered tube, and projects sufficiently beyond for the union connection. The
case is perforated with very small holes for the water to spray through. The tapered
tube with dome bottom, and tapered pipe attached as described, can be used to obtain
a spray without the case, by screwing on a bottom preferably concave, pierced with
numerous small holes. The pressure of water required to produce a spray being
obtained from a main, or by known means.

I EDGAR ALDOUS, of 2 Elmhurst Upton Lane, Forest Gate, in the County of Essex,
Engineer, do hereby declare the nature of my invention and in what manner the same
is to be performed, to bo particularly described and ascertained in and by the following
statement:-
This invention relates to a simple arrangement of apparatus for obtaining a water
spray of great efficiency and volume, and is particularly applicable for extinguishing
fires. The invention will be best understood by reference to the accompanying
drawings with aid of which I will proceed to fully describe my invention.
Figure 1 longitudinal side elevation partly in section.
Figure 2, a cross section at line X. Y. figure 1:
Figure 3, plan.
Figure 4, sectional view of a modification of preceeding figures.
Figure 5, outside view of bottom of figure 4.
A represents a case made in any suitable shape perforated with numerous small holes
for exit of water in direction of arrows. This case has an inside lining B, between the
outside of which and inside of A, is the passage for the water; C, the bottom of B,
through which a hole is cut; attached to bottom C, and covering the hole, is the large
end of a tapered tube D, fitted with a concave dome E, to hold air which is com-
pressed by the water and acts as a spring to the water in its expression; projecting
through the dome E, is the end of a tapered tube F, for the inlet of water; the
outside of tube F, being arranged for any suitable union connection to the supply pipe.
The upper end of tube D, is supported by the cover G.
Figure 4 shows the invention applied to a rose sprinkler, the sides, inlet tube, and
dome, being all cast in one piece. H, being the barrel part and I the dome. On the
bottom of H, is a screwed on rose J.
Having now particularly described and ascertained the nature of my Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. The arrangement of apparatus for giving a spray of water, substantially as
hereinbefore described and illustrated in the accompanying drawings at figures 1. 2. 3.
2. In an apparatus for producing water spray, the combination with a case A
perforated with small holes, of the lining B, and an inlet tube F, to introduce water
between lining and case, as described.
3. A rose sprinkler constructed substantially as described and illustrated in the
accompanying drawings at figures 4 and 5.
Dated this 26th day of June 1888.
