Improvements in Hand Fire-engines and Garden engines
Year: 1886

page_text: I, JOSIAH JOHN SNOW, residing at 151 Sandringham Road Dalston, London,
in the County of Middlesex, Gentleman do hereby declare the nature of this
invention to be as follows:-
Improvements in Hand Fire-engines and Garden engines are sought
1st. In the compact arrangement of the parts.
2nd. In the device of an easy and effectual mode of rendering them self
supporting.
3rd. In an easy action.
4th. In providing means for obtaining an exceedingly fine spray for diffusing
insecticides, washing plants, and similar applications.
The first of these objects is attained by having a ball shaped air vessel, b
Figures 1 and 4 surrounding the upright pump tube a, and placed near its lower
extremity. Valves d d which close the air vessel are arranged upon the pump-
tube a, at foot thereof.
The 2nd feature consists of a rack arrangement, placed on the pump-tube a in
which moveable rings, with chains g, g¹ attached, admit of an easy adjustment, to
suit any-sized pail; the chains g, g¹ are looped around the ears which carry the
bale or handle (Figure 4) and which secures the whole machine firmly in an upright
position, and make it and the pail virtually one.
The 3rd result is obtained by the use of a loosely fitting solid plunger f, without
packing at top, and an outlet c on pump-tube for the return of waste water to
the pail.
The 4th point receives its accomplishment by the use of a jet piece to be named
tbe "Helmet spray jet," and which consists of an ordinary jet, h (Figure 2), to the
screwed end of which a projecting piece can be attached, and made to bend over
(see Figure 3) in a point immediately in front of or facing the orifice / The
issuing stream of water strikes against this and becomes split up or minutely
divided. The extremity of a screw with milled top working in a head-piece
above, is found in connection with this device, most serviceable; as, it serves, by
means of a coarse or fine adjustment, to allow of a corresponding regulation of
the spray.
The support to this head-piece presents a "knife-edge" towards the hole, or
orifice k, gradually widening, to ensure strength, as it nears the outer circumference
of the jet.

Garden Engine, or the like.
I JOSIAH JOHN SNOW, of 151 Sandringham Road, Dalston, London, in the
County of Middlesex, Gentleman, do hereby declare the nature of my invention
for AN IMPROVED PORTABLE PUMP, TO BE USED AS A FIRE-ENGINE, GARDEN ENGINE,
OR THE LIKE, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference also being
had to the accompanying sheet of drawings:-
The improvements according to my Invention are distinguished by the following
features, that is to say-Firstly, in the compact arrangement of the several parts
of the apparatus according to my Invention. Secondly, by means of the device
hereinafter described, I am enabled to provide and ensure an extremely simple and
yet effectual mode or method of rendering the several parts of said apparatus,
self-supporting. Thirdly-the portable pump according to my Invention, dis-
tinguishes itself when being used, by its remarkably easy action. Fourthly:-
I am enabled to obtain an exceedingly minutely divided, fine spray which may be
utilised with advantage especially in connection with horticultural operations, such
for instance as diffusing insecticides, washing plants and so forth.
This last mentioned feature of my Invention will be readily appreciated by
nurserymen.
Referring to the accompanying sheet of drawings, Figure 1 represents by an
elevational view, the improved, portable pumping apparatus herein referred to.
Figure 2 represents to an enlarged scale the nozzle attachment for discharge
pipe C. Said nozzle being screwed as shewn at the outer end to allow of the
connection thereto of the "Helmet" spray jet, shewn in the detached, enlarged
view Figure 3. Figure 4 represents the apparatus placed as it usually would be
for convenience, in an ordinary house pail.
In carrying out my Invention I provide a spherical air vessel or chamber B,
(Figures 1 and 4) surrounding the pump tube A and placed as shown at the lower
end of said pump tube; this latter is formed with an enlarged and closed portion
at the base, provided circumferentially with perforations f as shewn, forming inlet
apertures to the interior of the pump through an ordinary inlet valve d-d³ being
the valve which closes the air vessel or chamber B aforesaid.
The arrangement hereinbefore referred to in connection with the second feature
of my Invention, is shewn in Figures 1 and 4, and comprises a series of nodules
or projections g, g-presenting a rack-like formation-outside of a portion of the
pump tube A and in which, movable rings G, with connecting chains G¹, admit of
ready attachment and adjustment to suit any sized pail. The lower end of each of
said chains G¹.is looped around the ears which carry the bale or handle of pail
(Figure 4) and which secures the whole machine firmly in an upright position, and
thus making it and the pail containing the water or other liquid virtually one.
Referring to the third feature herein before alluded to as one of the characteristics
of my Invention, namely that which consists in the remarkably easy working of
the pump; the plunger F which I employ, is a solid plunger without any packing

page_text: at the upper end. The enclosing pump tube or barrel A is provided with a
surrounding hollow chamber or receptacle E, with a slight intervening space at the
top E between this part of the chamber E and the pump tube or barrel A. Any
overflow water which may be projected over the top A¹ of the pump tube or
barrel A will flow down the outside of said pump tube or barrel, and entering the
chamber E at the annular opening E will be discharged through the apertures e
formed in the lower half of the chamber E, and passing thence would be received
in the pail or other reservoir in which the pump is placed; thus preventing the
waste of water or any other liquid employed.
In reference to the fourth feature hereinbefore referred to in connection with
my Invention the following is a description of the means which I employ that is to
say, a jet piece as shown on an enlarged scale Figure 2, would be attached to the
outer end of the delivery pipe C (Figures 1 and 4). The discharge or nozzle end
of said jet piece is screwed as indicated at K, (Figure 2), to allow of there being
adapted thereto the helmet shaped device or cap piece shewn to an enlarged scale
Figure 3, with an orifice k at the apex of said helmet piece or attachment which is
provided as shewn (Figure 3) with a bracket a having at the curved portion at the
top thereof a boss with a screwed opening therein, through which passes a screwd
pin a¹ with a milled head a". When the apparatus according to my Invention is to
be used for disseminating a minutely divided fine spray, the jet piece aforesaid
being connected to C, and with the helmet attachment screwed on at K; then, on
the pump plunger F being operated, the stream of water issuing at k will impinge
upon the point of the screw a¹ and. become split up or minutely divided; the
spraying effect being easily regulated to any desired extent by means of the
adjustable screw pin a¹ with milled head a"-The support or bracket a presents a
knife edge towards the aperture k gradually widening-to ensure strength-as it
approaches the outer circumference of the jet.
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
The improved portable pump and accessory parts substantially as herein set forth
and shewn in the accompanying sheet of drawings.
