PROVISIONAL SPECIFICATION.
Improvements in Jets for Water.
I, PIERRE PERRINON, of 17, Rue de Plaisance, Asnèires, in the Republic of
France, Commandant, do hereby declare the nature of this invention to be as
follows:-
My present invention has for its object improved methods of constructing jets
for water pipes, by which either a single stream, or a shower or spray, can be
obtained.
In the arrangements ordinarily used, two distinct jets have to be used, one of
which is unscrewed from the pipe or cock and replaced by the other when
necessary, considerable inconvenience being thus caused, as the screwed joint is not
always tight, whilst by further tightening it up to prevent leakage it becomes
difficult to unscrew.
One or other of the jets is, moreover, often lost or missing,
and the cost of the apparatus is considerable.
By my present invention, I leave the jet which delivers a single stream,
permanently attached to the cock upon the water pipe or hose, and outside it near
its outer end I form a screw thread upon which the second distributing jet or rose,
giving a shower or spray, can be screwed when desired.
By this arrangement there is therefore only one separate piece instead of two.
In another form of arrangement I do away with both moveable jets. For this
purpose I make the plug of the cock upon the water pipe or hose of such form
that it not only serves to admit and shut off the water but also to give both a
single jet of water or a distributed shower or spray, as may be desired.
I make the transverse hole or passage through the plug, conical, one end forming
a small hole, whilst the other is of much larger diameter and has fitted
into it a thin plate perforated with a large number of small holes so as to produce
a shower of water.
The outer discharge opening of the cock itself is made of sufficient size to deliver
the water discharged through such perforated plate.
By turning the plug, therefore, in one or the other direction, either a single jet
or a distributed shower or spray is produced, and the apparatus is simple, cheap,
and saves time and trouble.
The shape of the hole through the plug may be varied more or less to suit
different circumstances, and the plugs of existing cocks may be altered to the shape
and to serve the purposes described.

COMPLETE SPECIFICATION.
Improvements in Jets for Water.
1, PIERRE PERRINON, of 17, Rue de Plaisance, Asnières, in the Republic of
France, Commandant, 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 and accompanying drawing, that is
to say :-
My present invention has for its object improved methods of constructing jets for
water pipes, by which either a single stream, or a shower or spray, can be
heained

page_text: :
In the arrangements ordinarily used, two distinct jets have to be used, one of
which (giving a single jet) is unscrewed from the pipe or cock and replaced by the
other when necessary, considerable inconvenience being thus caused, as the screwed
joint is not always tight, whilst by further tightening it up to prevent leakage it
becomes difficult to unscrew. One or other of the jets is moreover often lost or
missing, and the cost of the apparatus is considerable.
By my present invention (which is illustrated in the accompanying drawing)
these objections are lessened or avoided. For this purpose I leave the jet L
(Figures 1 and 3) which delivers a single stream, permanently attached to the
cock R (Figure 1) upon the water pipe or hose, and outside it near its outer end
I form a screw thread V upon which the second distributing jet or rose A
(Figure 2) giving a shower or spray can be screwed when desired.
By this arrangement therefore only one separate piece A, instead of two, is
required.
In another form of arrangement I do away with both moveable jets L and A
and thus completely avoid the inconveniences mentioned above.
For this purpose
I make the plug C (Figures 5 and 6) of the cock upon the water pipe or hose of
such form that it not only serves to admit and shut off the water but also to
give both a single jet of water or a distributed shower or spray as may be desired.
I make the transverse hole or passage through the plug, conical, one end forming
a small hole a (Figures 5 and 6) whilst the other A is of much larger diameter
and has fitted into it a thin plate P (Figures 4, 5, and 6) perforated with a large
number of small holes so as to produce a shower of water.
The outer discharge opening of the cock itself is made of sufficient size to deliver
the water discharged through such perforated plate.
By turning the plug therefore, in one or the other direction, either a single jet
or a distributed shower or spray is produced, and the apparatus is simple, cheap,
and saves time and trouble.
By this novel method of construction as described and shewn, the part between
the cock and the jet is omitted, and the cock (the plug of which is capable of
discharging a single jet or a number of jets) will take the simple form shewn in
Figures 4 and 5.
The shape of the hole through the plug may be varied more or less to suit
different circumstances, and the plugs of existing cocks may be altered to the
shape and to serve the purposes described, by making the passage through them
small at one end, for a single jet, and of increased size at the other end which is
covered by a plate perforated with numerous small holes.
I do not confine myself to the precise details of form and arrangement, which
may be varied more or less as may be found desirable to suit varying circum-
stances, but
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. The combination with the cock R of the jet L. permanently screwed upon it
and itself screwed to receive the separate jet A when required, substantially as
described and shewn in Figures 1 and 2.
T
2. The combination in the cock R, of the plug C having a transverse passage
through it larger at one end a than at the other, the larger end being closed by a
transverse plate perforated with small holes, substantially as and for the purpose
described and illustrated in Figures 4, 5, and 6.
