PROVISIONAL SPECIFICATION.
An Improved Delivery Nozzle for Water, Steam, or other Fluids.
I, FREDERICK SCHOLEFIELD, of 13 Ellison Street, Jarrow-on-Tyne, in the
County of Durham, Engineer, do hereby declare the nature of this invention to be
as follows:-
My invention relates to the improved construction of a delivery nozzle,
applicable for use with garden hose, for cleaning ships, windows, yards, and other
purposes.
My improved nozzle consists substantially of a plug, preferably of conical form,
fitting within an outer shell. The said plug is provided at one end with any
suitable means for the attachment of the hose, or pipe, and at the other and smaller
end, with a short nozzle.
The shell is provided with two or more external wings, or other suitable devices,
to enable it to be conveniently rotated around the plug by hand. The plug is
hollow, and is formed with a central transverse diaphragm, or partition, dividing
the internal space into two parts, which can be caused to communicate with each
other in the following manner. Two long open chambers are formed inside the
shell, longitudinal with its axis and opposite to each other. On each side of the
aforesaid partition in the plug, and on opposite sides of the plug, port holes are
provided, communicating with the chambers aforesaid, so that by rotating the shell,
the delivery can be shut off, opened full, or regulated to give either a fine or strong
spray, or full stream, as required.
The central partition has the effect of intercepting the direct stream and causing
it to be broken up into spray when the nozzle is only partly open, while when fully
open a straight stream is delivered.
My improved nozzle is applicable for use with water, steam, and other desired
fluids.

COMPLETE SPECIFICATION.
An Improved Delivery Nozzle for Water, Steam, or other Fluids.
I, FREDERICK SCHOLEFIELD, of 13 Ellison Street, Jarrow-on-Tyne, in the
County of Durham, 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 :-
My invention relates to certain new and useful improvements in the construction
of delivery nozzles, applicable for use with garden hose, for cleaning ships, windows,
yards, and other purposes.
In the accompanying sheet of drawings, Fig. 1 is a longitudinal section, and
Fig. 2 is a cross-section through A A in Fig. 1 of a delivery nozzle constructed in
accordance with my invention.
The said nozzle consists of a plug B, preferably of conical form, as shewn in
Fig. 1, fitting fluid tight within an outer shell C.
The said plug is provided on one end with any suitable means for the attachment
of the hose or pipe.

page_text: for insertion in a rubber hose, such extension may be formed in one piece with the
plug, or may be connected thereto in any suitable manner.
The other end of the plug has a delivery nozzle E, screwed therein.
The outer shell C is provided with two or more external projections F F, and a
milled rim F, to enable it, when grasped by the hand or fingers, to be conveniently
rotated around the plug B. The said plug is hollow, but it is formed with a central
transverse diaphragm, or partition H, dividing the internal space into two parts,
which can be caused to communicate with each other in the following manner.
Two long open recesses or chambers J Jare formed inside the projections F F in
the shell C, longitudinal with its axis and opposite to each other. On each side
of the partition H in the plug B and on opposite sides of the plug, ports K, K',
K2, K, are provided, which can communicate with the recesses JJ. When the
shell C is in the position shewn in the drawings with relation to the plug B, the
fluid entering the extension D can pass to the nozzle E, by way of the port K¹
recess J and port K, and also by way of the port K³, recess J and port K², and in
such position the apparatus is open to its fullest extent. It will now be manifest
that if the shell C is slightly rotated on the plug B, the ports K, K', K², K³, will
be partially closed by the advancing edges of the recesses J J and the outflowing
stream of fluid consequently reduced in volume, while if such rotation of the shell
be continued till the recesses have passed the ports, the nozzle will be closed and
no fluid can pass. By thus merely rotating the said shell the delivery can be
instantly shut off, opened full or regulated in amount as required. The central
partition H has the effect of intercepting the direct stream, and, in the case of
water, or similar fluid, of causing it to be broken up into spray when the apparatus
is only partly open, while when fully open a straight solid stream is delivered, and
such capability of readily varying the nature of the discharge, forms a feature of
considerable utility.
By unscrewing the nozzle E the shell C can be removed when required for
cleaning or other purposes, and adjustment for wear may be provided by varying
the thickness of the washer L inserted between the end of the shell and the
shoulder M of the nozzle. The plug B and shell C may be cylindrical, if
desired, but the conical forin is more easily constructed and maintained fluid tight.
I do not confine myself to the two sets of ports and recesses herein shewn and
described, as 1 may, if desired, provide three or more sets of such ports and
recesses.
My improved nozzle is applicable for use with water, steam, and other fluids.
Having now particularly described and ascertained the nature of iny said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim, is:-
1. In a delivery nozzle, a hollow plug having a central diaphragm, ports on each
side of said diaphragm communicating with interior of said plug, a shell surround-
ing said plug and having internal recesses, placing the ports on opposite sides of
said diaphragm in communication, so that by rotation of said shell, said nozzle
may be opened fully, partly opened, or closed, substantially as described.
2. In a delivery nozzle, a hollow conical plug B, having an extension D, a central
diaphragm H, ports K, K2, on one side and ports K, K³, on the other side of said
diaphragm communicating with interior of said plug, a shell C surrounding said
plug, held in place by a nozzle E and having projections F, F, and internal
recesses J, J, so arranged that by rotation of said shell, said nozzle may be opened
fully, partly opened, or closed, substantially as described.
