COMPLETE SPECIFICATION.
Improvements in Spray Nozzles, specially applicable to Urinals
and the like.
JOSEPH H. SAVILL, Manufacturer, of 1229 Budden Street, Philadelphia,
in the State of Pennsylvania, U.S.A. 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 :—
which
My invention relates to improvements in that class of sprays
are employed
to cleanse slab-urinals, and it has for its general object to provide a spray nozzle
for such purpose, of a cheap and simple construction, and oue which may be
readily adjusted to enable the water to cleanse its discharge-aperture or apertures
of dirt, etc., which is likely to clog up said aperture or apertures and thereby
impair the usefulness of the nozzle.
Other objects and advantages of the invention will be fully understood from
the following description and claims when taken in connection with the annexed
drawings, in which:
Fig. 1, is a perspective view of a slab-urinal equipped with my improvements..
Fig. 2, is a vertical section on an enlarged scale illustrating the nozzle in
conjunction with the supply, pipe and a portion of the urinal slab, and:
Fig. 3, comprises. perspective views of the parts that go to make up my improved
nozzle.
Referring by letter to said drawings: A, indicates a urinal-slab; B, indicates
the water supply pipe which is generally arranged in a horizontal position at a
point adjacent to the upper end of the slab and is provided with a screw tapped
aperture a, and C, indicates my improved spray nozzle. This nozzle C, may be
made in any suitable number of parts, but I prefer in practice to form it of the
body D, the cap E, and the nut F, better illustrated in Fig. 3. The body D,
which is preferably of a circular form and chambered as shown, has one of its
sides open and a central aperture 6, in its opposite side, and it is provided in the
edge c, of its open side, which is bevelled inwardly, as better illustrated in Fig. 2,
with five (more or less) radially disposed grooves d, which extend the full width
of said edge and are designed for a purpose presently described. The body D, is
furthermore provided with the guide studs F', which extend laterally from its
edge c; and on these guide studs is designed to be mounted the cap E, which has
apertures e, to receive the studs as shown in Fig. 2. This cap E, has its inner
side bevelled, as shown.at el, in conformity to the bevelled edge c, of the body, and
it is provided in said side with radial grooves, which are designed to register with
the grooves d, in the edge of the body and form discharge or jet apertures. Said
cap E, is connected with the body by the lateral bolt or stem G, and this bolt or
stem which is threaded is designed and adapted to extend through the chamber
and aperture b, of the body and be provided with the nut F, which serves to hold
the cap in its proper position.
The body D, of .my.nozzle is. provided with an externally-threaded branch g,
designed to engage the threaded aperture a, in the pipe B, and in the said branch
is formed a bore h, for the passage of water from the pipe B, to the interior of the
nozzle.

In the practice of my invention, the nozzle is connected to the underside of the
supply pipe with the cap E, contiguous to the urinal slab A, and when the nozzle
is in this position, it will be seen that the water, by reason of the bevelled edge of

page_text: the body and the correspondingly bevelled side of the cap, will be discharged
through the jet apertures at an angle to the slab and striking the same will serve
to cleanse it and keep it in a clean and wholesome state. When any one or more
of the jet apertures are choked by dirt so as to impair the usefulness of the nozzle,
as frequently happens in this class of devices, it is simply necessary to loosen the
nut F, when the pressure of water acting against the cap E, will force said cap
away from the body so as to separate the grooves forming the jet apertures, and
will quickly remove the dirt, etc. from said grooves. When the cap is moved away
from the body for the purpose above stated, the studs F¹, serve to guide and hold
the cap in its proper relative position so that when the nut is turned to draw the
cap against the body, the grooves d, f, of the body and cap will register to form
the jet or discharge apertures. Thus it will be seen that the nozzle may be easily.
kept in an efficient condition, and as a result the whole surface of the slab will be
subjected at all times to the action of the water and will consequently be kept in
a clean and wholesome condition.
In some cases, the narrow grooves d, and f, of the body D, and cap E, may be
dispensed with and said body and cap may be provided with one or two grooves
of great width designed to register when the cap is drawn against the body and
form elongated discharge openings adapted to spray the water in sheets against
the urinal slab.
I have in some respects specifically described the construction and relative
arrangement of the several parts of my improved nozzle in order to impart a clear
and exact explanation of the same, but I do not désire to be understood as confining
myself to such construction and arrangement, as I may make such changes or
modifications, in practice, as fairly fall within the scope of my invention.
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. A spray nozzle comprising a body having one of its sides open and a central
aperture 6, in its opposite side and also having a groove in its edge, and a lateral
guide stud .F, a cap having an aperture to receive the guide stud F', of the body
and a groove adapted to register with the groove of the body and also having a
threaded stem adapted to extend through the open side and aperture b, of the
body, and a nut mounted on the end of said stem, substantially as specified.
2. The combination with a urinal slab; of a water supply pipe and a spray
nozzle connected to said pipe and comprising a body having a central aperture in its
outer side and its side contiguous to the slab open, and a bevelled edge c, surrounding
the opening and also having a groove in said bevelled edge and a lateral guide
stud F, arranged off its centre, a cap arranged between the body and the slab
and having an aperture to receive the stud F, and also having its inner side
bevelled and provided with a groove adapted to register with the groove of the
body and a central bolt connecting the cap with the body, as and for the purpose
set forth.
