PROVISIONAL SPECIFICATION.
Improvements in Syringes and like Apparatus for Use in connection
with Hose.
I WILLIAM BARBER PRESS of 5 Lansdowne Villas High Road Leytonstone
in the County of Essex Mechanic do hereby declare the nature of this invention to
be as follows:-
This my invention relates to syringes and the like apparatus for ejecting water
and other liquids
And consists First in a novel system of feeding the said syringe.
Secondly in the construction of the syringe which I now describe. A cylindrical
barrel having at one end a single or spray jet which I here and hereafter call the
outlet is furnished with a perforated valved piston the valve opening to outlet, the
rod of the piston passes through the cap head and is kept air tight by the stuffing
in stuffing box provided and is furnished with a handle near the stuffing box and at
the side thereof on the cap head is the inlet tube preferably fitted with a stop tap,
fly nut and union. Now it will be seen the hose being fixed onto the inlet tube and
charged a constant flow passes the valve and out at outlet as from an ordinary
watering rose but should additional force be desired it is at once obtained by
working the piston.

Improvements in Syringes and like Apparatus for Use in connection
with Hose.
I, WILLIAM BARBER PRESS, of 5 Lansdown Villas, High Road, Leytonstone,
Essex, Engineer, 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 has reference to certain new and useful improvements in syringes
and like apparatus for use in connection with hose.
The object of the invention is to provide means whereby the force of a stream of
water ejected from a hose may be considerably increased so as to render it capable
of removing blight and such like from trees or plants. The invention will also be
found useful in all cases where a high pressure is required.
The invention consists, firstly, in the construction of the syringe whereby it is
rendered capable of ready attachment to an ordinary hose; secondly, of ineans
whereby the water or other fluid ejected from the hose may be turned off at will;
and thirdly, the construction of the piston of the syringe.
In the drawings, in which like parts are represented by like letters of
reference,
Fig. 1. is a side elevation, partly broken away, illustrating a syringe with a hose
attached thereto :
Fig. 2., is a front elevation of the rear portion of Fig. 1.; the view being taken
on the line in the direction of the arrow-head:
[i]

page_text: Fig. 3., is an elevation of the rear portion of the syringe; the piston-rod and
hose being removed;
Fig. 4., is a sectional side elevation of the rear part of the syringe and the hose
connected thereto, shewing the hose open for the passage of fluid:
Fig. 5., is a similar view to Fig. 4., but shewing the passage for the fluid
closed:
Fig. 6., is a side elevation of the valved piston; Fig. 7., is a side sectional view
thereof; and Figs. 8 and 9 are rear and front end-elevations thereof respectively:
Figs. 10 and 11, are plan and elevation respectively of a part of the syringe
hereinafter described.
The syringe comprises the usual barrel A fitted with any desired rose or jet B,
valved piston C, piston-rod D and handle E.
In place of the ordinary cap which is usually fitted to that part of the syringe
indicated by the linea, the casting or head F is attached as shewn in Fig. 1.
This casting is preferably and substantially of the shape shewn, and is formed with
a screw-threaded socket G to engage the screw-threaded end of the barrel A. It
is also formed with an aperture H to accommodate the end of an ordinary hose.
pipe I; one side J of said aperture being curved and projected inwardly in order
to press one side of the hose-pipe towards the centre of the casting as shewn clearly
in Figs. 4 and 5. In order to prevent the hose-pipe from being inserted too far
into the casting, and also to serve as guides for the part T hereinafter referred to,
stops K are formed integral with and at each side of the casting, as shewn clearly
in Figs. 2, 4, and 5. Stuffing-boxes L, M, fitted with glands N, O, are provided;
the former to permit of the passage through the casting F of the piston-rod D, and
the latter to prevent leakage around the screw-stem P which passes through the
stuffing-box M and a screw-threaded aperture in the bottom thereof. The screw-
stem P is reduced at Q to form a head R which passes between and under the lips S
of the shoe T preferably shaped as clearly shewn in Figs. 10 and 11.
A simple and effective method of making a water-tight connection between the
hose-pipe I and the casting F consists of tapering the entrance to the aperture H
of the latter, to accommodate a rubber or other flexible ring U, which, when pressed
inwardly by the nut V, is forced tightly around the hose-pipe I thereby making
a perfect water-tight joint, and at the same time retaining the hose-pipe firmly in
place.
The valved piston C consists of a cylindrical body grooved upon its outer surface
to accommodate the usual packing C, Fig. 1., and integrally formed with webs D¹
and a central part E' which may be brazed, soldered or otherwise secured to the
piston-rod D in the usual and well-known manner. The part E has a central
bore F in which the shank G¹ of a rivet-shaped piece of metal H' is loosely fitted,
and upon which is fitted a leather or other suitable washer I'. This washer is
adapted to fit closely against the webs D' and the periphery of the interior
portion J of the body C. The valve-consisting of the part H' and washer 1',—
is retained in place by projecting parts K' of the body C.
When in operation, the screw-stem P is withdrawn as shewn in Fig. 4., and an
unobstructed passage for the water is thereby opened through the hose-pipe I,
casting F, syringe barrel A, valved piston C, and the rose or other outlet or
nozzle B. When however a greater force is required, the syringe-handle E is
withdrawn, and then forcibly returned. This action causes the water in the
barrel A, in front of the piston C, to be very forcibly ejected as will be readily
understood. In order to diminish or arrest the flow of water, the screw-stem P is
screwed inwardly until that part of the hose-pipe within the casting F is forced
together as shewu clearly in Fig. 5.
It will be readily understood, that when the water-supply is shut off, the whole
pressure thereof is concentrated upon the sides of the hose-pipe, and that therefore
a rapid or sudden cessation of the flow of water will not tend to strain the joint
at W and possibly disunite the casting F and hose-pipe I. It will be further
understood that, should that portion of the hose within the casting become

page_text: deteriorated said portion can be readily removed and cut off, and the end of the
hose-pipe be reinserted into the casting.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In syringes and like apparatus for use in connection with hose, a casting formed
with a screw-threaded socket to engage the rear screw-threaded end of the syringe-
barrel, stuffing-boxes cast integral with said casting and fitted with glands, one
stuffing-box to permit the water-tight passage through the casting of the syringe
piston-rod, the screw-stem passing through the other stuffing-box and the screw-
threaded aperture in the same, the shoe loosely fitted to the inner end of the screw-
stem, the casting formed with an aperture adapted to contain the end of a hose-pipe,
a flexible ring contained within the tapered entrance to said aperture and the nut
screwed over the externally screw-threaded part of the casting and pressing upon
the flexible ring, and the stops formed integral with the casting, all substantially as
and for the purposes hereinbefore set forth.
2. In syringes and like apparatus for use in connection with hose, the valved
piston C, consisting of the cylindrical body exteriorally grooved to retain the
packing, webs J¹ connecting said body with the central part E, said part centrally
bored to receive the part G₁ of the part H¹, the flexible washer I¹ fitted over the
part G' of the part H', and the projecting parts K' of the body C, all substantially
as and for the purposes herein before set forth.
