Kingston upon Hull Plumber, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct a syringe by which means a jet or spray
may be obtained at will.
I construct a syringe with cylinder and piston as usual with collar screwed to
receive combined cap end. In accompanying drawings I illustrate in figure A a
sectional view of a combined syringing cap end when used as jet or spray. I prefer
to construct a metal plate with ground in apertures of any convenient size one of
which apertures has a nozzle sufficiently long to pass through outer cap or cover
which nozzle forms the jet tube whilst the other aperture allows the water or other
liquids to pass into the perforated cap or cover to form spray-metal ball or valve is
forced into one of the ground in apertures by the downward motion of piston according
to the position in which syringe is held-metal ball or valve is held in position by
guide plate as shewn in cross section A which prevents metal hall or valve being
drawn into cylinder by the upward motion of piston but sufficient space is allowed for
metal ball or valve to pass freely from one aperture to the other. The metal plate is
also screwed a short distance from the screwed collar to receive screwed outer cap or
cover which cap or cover is perforated to produce spray on which cap or cover are the
words "jet "" spray as shewn in sketch. On the upward motion of piston the
water or other liquids are drawn through jet and spray of syringing cap end at
the same time when, on the downward motion of piston jet or spray is obtained
according to the name which is held uppermost.

page_text: I JOHN HOWLETT of 10 Albert Terrace Terry Street in the Town and County of
Kingston upon Hull Plumber, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of this invention is to construct a syringe for garden or other like
purposes whereby without the removal of any of the parts a single jet or shower may
be obtained at will.
I construct a syringe with cylinder and piston in the usual manner with collar
screwed to receive combined cap end. In accompanying drawings I illustrate in
figure 1 a sectional view of a combined syringing cap end showing ball or valve in
position for the syringe to be used as jet. In figure 2 I also illustrate in section
position of metal ball or valve when syringe is being used as shower. I prefer to
construct a metal plate with apertures of any convenient size the seatings in which
metal plate are made perfectly true, one of which apertures has a nozzle sufficiently
long to pass through outer cap or cover which nozzle forms the jet tube the other
aperture allows the water or other liquids to pass from the cylinder into the shower
chamber thereby producing shower metal ball or valve is forced into one of the
apertures by the downward motion of piston according to the position in which syringe
is being held. It will be noticed that in figures 1 and 21 construct metal plate with
jet tube in the centre but in figure 3 1 illustrate metal plate with jet tube slightly
curved so as to be in the centre of perforated cap or cover. I prefer to construct the
jet tube perfectly straight whenever practicable thereby obtaining the full force of
water when syringe is being used as jet but it will be noticed that in figure 3 I
illustrate syringing cap end on a smaller scale when jet tube must be curved so as to
allow the apertures to be made in metal plato which apertures form seatings for metal
ball or valve. It will be noticed that in figures 1, 2 and 3 I illustrate metal plate so
constructed that it can be screwed on to the screwed collar of cylinder of syringe,
between which metal plate and screwed collar is inserted a thin leather or other
washer, a perforated cap or cover is made in a separate piece and screwed on to
screwed shoulder of metal plate as illustrated on which cap or cover are the words
"jet"
"shower." On the upward motion of piston the water or other liquids is
drawn through jet and shower of syringing cap end at the same time but on the
downward motion of piston jet or shower is obtained according to the name which 'is
held uppermost.

cap
In figure 4 I illustrate cross section through the tube looking towards the syringing
end as in figures 1 and 2 showing the view with guide plate removed.
In figure also illustrate cross section through the tube looking towards the cap
end as in figures 1 and 2 showing the view with guide plate in position which guide
plate prevents metal ball or valve being drawn into cylinder of syringe by the upward

motion of piston but sufficient space is allowed for metal ball or valve to pass freely
from one aperture to the other. The guide plate is screwed or fixed into metal plate
by any convenient means. It will be seen that when syringing cap end is constructed
as illustrated in figure 3 the guide plate will be central with the tube.
In figures 6 and 7 I illustrate another mode of making a combined syringing cap
end. I construct a metal plate with apertures of any convenient size the face or seat
of which metal plate is made perfectly true-metal valve or slide is also constructed
with a smooth surface which valve or slide is about two thirds the length of diameter
of metal plate. I also have an aperture at one end of metal valve or slide which valve
or slide according to position in which syringe is being held allows jet or shower to be
obtained by simply turning syringe in the band as illustrated in figure 6 shewing
section through cap end with slide in position for syringe to be used as shower and in
figure 7 showing section through cap end showing slide in position for syringe to be
used as jet. It will be seen from the illustrations figures 6 and 7 that the aperture
for jet in metal plate is formed in the centre which allows jet tube to be made
perfectly straight so as to obtain the full force of water when syringe is being used as
jet but metal plate may also be made with an aperture at either side when jet tube
would have to be curved so as to be in centre of perforated cap or cover as illustrated
in figure 3 when metal valve or slide would be made without an aperture at one end.
In figure 8 I illustrate cross section through the tube looking towards the cap end
(as in figures 6 and 7) showing metal plate with apertures over which apertures is
metal valve or slide which valve or slide is held in position by metal clip or bar and
two small screws or any other convenient means. A sufficient space is allowed
between metal plate and valve or slide to allow for water or other liquids to enter
freely through both jet and shower of syringing cap end at the same time by the
upward motion of piston, but on the downward notion of piston metal valve or slide
is forced up to face or seat of metal plate when jet or shower is obtained according to
the position in which syringe is being held as described and illustrated in figures 6
and 7.
Figures 9 and 10 are a modification for forming combined syringing cap end to
receive metal plate with apertures. It will be noticed that in figure 10 perforated cap
or cover with a small ledge or rim at the inside on which ledge or rin rests metal
plate with apertures which metal plate is held in position when metal cap or cover is
screwed on to screwed collar of cylinder between which screwed collar and perforated
cap or cover is inserted a thin leather or other washer. In figure 10 I also illustrate
another mode of making a syringing cap end. I construct metal plate with jet tube
and apertures. A short distance from the outlet end of jet tube I construct a small
ledge or rim which ledge or rim is at the inside of perforated cap or cover when metal
plate with apertures is in position. The end of jet tube which is screwed is then a
short distance through the perforated cap or cover on to which tube is screwed a small
nozzle or jet end.
In figure 9 A I illustrate half cross section through the cap end as shown in figure 10
showing the elevation of the ledge or rim cast on same to receive the metal plate and
also one of the pins which are cast on the inside of perforated cap or cover to keep the
metal plate with apertures in position.
Figure 9 B is half clevation of the metal plate with apertures showing one of the two
notches made in metal plate to fit the pins shown in figure 9 A that would be used with
the perforated cap or cover as shown in figure 10.
In figures 11 and 12 I illustrate another mode of making syringing cap end.
In
figure 11 illustrate metal plate with apertures and raised seatings one of which
seatings is covered by hinged flap as shown in section when syringe is being used 'as
shower. I prefer to make metal flap about one eighth of an inch in thickness with
one end shaped to fit between guide or lugs which are cast on metal plate with holes
made in the centre into which holes is inserted a small screw or pin which keeps metal
flap in position and at the same time allows metal flap to work easily from one side of
metal plate to the other thereby covering the jet or shower seat according to the
position in which syringe is being held.

page_text: In figure 12 I illustrate syringing cap end showing flap in position to produce jet.
It will be seen that in figure 12 metal plate is constructed without the raised seatings.
In this case I construct metal plate with apertures the face of which metal plate is
made perfectly true when metal flap is constructed of greater thickness than as illus-
trated in figure 11. In this case I prefer to construct metal plate about a quarter of
an inch in thickness with one end shaped to fit between metal lugs or guide which
flap is held in position with small screw or pin as already described and as illustrated
in figure 13 thereby allowing metal flap to work easily from one seating to the other
according to the position in which syringe is being held. On the upward motion of
piston water or other liquids are drawn through jet and shower of syringing cap end
at the same time but on the downward motion of piston jet or shower is obtained
according to the name which is held uppermost.
Figure 14 is cross-section through the tube looking towards the cap end (as in
figures 11 and 12) showing the view with metal flap removed.
Figure 15 is also a cross section through the tube looking towards the cap end
(as in figures 11 and 12) showing the view with metal plate as illustrated and
described.
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.
