COMPLETE SPECIFICATION.
Improvements in Fire Extinguishing Tanks.
I, PHILIP CASEY, Junior, of No. 210, Atlantic Street, in the City of Paterson,
County of Passaic, and State of New Jersey, U.S.A., Gentleman, 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:-
The object of my invention is to provide a fire extinguishing tank, of simple,
strong and durable construction, and which tank is to be connected with a hydrant
and a fire engine respectively, whereby the water passing through said tank
dissolves a certain quantity of the rock salt arranged in said tank.
The invention consists in the improved fire extinguishing tank, and in the
combination and arrangement of the various parts thereof, substantially as will
be hereinafter more fully described and finally embodied in the clauses of the
claims.
In the accompanying drawing, Fig. 1, is a side elevation of my improved fire
extinguishing tank, partly in section and certain portions removed, to better
illustrate the nature of my said invention, and Fig. 2, a sectional view on the
line of Fig. 1.
In said drawing a represents a cylindrical tank-preferably of wood and pro-
vided in its top portion with an oval hole or opening b, having beveled edges and
adapted to receive a correspondingly shaped lid or cover c, penetrated by a bolt d,
to the lower portion of which is secured an arm e-serving to look said lid to said
tank--as will be manifest.
Within the tank a are arranged a series of grates f, f, consisting of a
substantially circular rim or flange g and of a series of vertically arranged bars or
rods h. The upper portions of said grates are secured to a rectangular frame
provided with an angular groove m, whilst the lower portions of said grates are
supported by a rod or bar n-in turn supported by legs o, as clearly illustrated in
the drawing.
The angular grooves m in the shorter sides of the rectangular frame i are adapted
to be engaged by the free ends of grated lids p, the other ends of which are sup-
ported by the heads of the tank as shown, as at q, q, in Fig. 1.
The angular grooves m of the longer sides of said rectangular frame i are adapted
to be engaged by the free ends of the grated lids r, the other ends of which are
pivotally secured as at s, s, to the inside of the tank a.
It can be seen, from the foregoing that the top frames, which is connected with
the series of grates f is securely held in position by means of said grated lids ?
and resting with their free ends in the angular grooves of said frame i.
The inlet pipet penetrates the head of the tank a and is secured to and within
the end grate adjacent to said head, and is provided with a valve of ordinary
construction.
A similarly constructed pipe u with valve ¹ penetrates the opposite head of the
tank a and is secured to and within the end grate-as clearly illustrated.
The outer ends of both of these pipes are screw threaded so that they can be
conveniently connected with the coupling of a hose leading to the hydrant and fire
ancine respectively.

page_text: Within the bottom of the tank a is arranged another pipe with valve ³ for the
purpose of emptying said tank when so desired.
It must be remarked that the chamber formed between the grates and the tank
(and closed by the grated lid p and r) is filled with rock salt, and the water entering
through the pipe and leaving through the pipe u dissolves a certain amount of
said rock salt, which greatly assists in extinguishing fires, as will be manifest.
The rock salt is inserted through the hole or opening 6 in the top of the tank and
is closely packed within the chamber heretofore mentioned.
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. A fire extinguishing tank comprising a cylindrical tank provided in its
bottom with an outlet and in its top with a lid covered opening, a series of parallel
grates within said tank and each consisting of a substantially circular rim and of
a series of vertical rods or bars, a rod or bar connecting the lower portions of said
grates, a rectangular frame connecting the top portions of said grates and provided
with an angular groove, grated lids supported by said tank and engaging with their
free ends said angular grooves of the rectangular frame, and an inlet and outlet
pipe penetrating the opposite heads of said tank and secured to and within their
respective end grates, all said parts, substantially as and for the purposes described.
2. In fire extinguishing tanks, the combination of the various parts of mecha-
nism substantially as above described in this specification, and illustrated in the
accompanying drawing.
