IMPROVEMENTS IN ROSE-HEADS OR NOZZLES FOR THE DIFFUSION OF SPRAY
Year: 1885

page_text: I ALBERT FERDINAND LINK of 8 Union Court Chambers Old Broad Street in
the City of London, Merchant do hereby declare the nature of my Invention
for IMPROVEMENTS IN ROSE-HEADS OR NOZZLES FOR THE DIFFUSION OF SPRAY,
a communication from abroad by Max Mestern, of Dresden, in the kingdom of
Saxony, Manufacturer, to be as follows:-
The object of my invention is to effect improvements in rose-heads or nozzles for
diffusing spray, whether used in ventilating apparatus to cleanse the air from fine
dust, or in baths, or otherwise.
I construct such rose-heads or nozzles either of a bell or cylindrical form, and
usually of brass, one end of which is screwed or otherwise connected with the
supply pipe; suitable openings being provided to admit the water, or other liquid,
to the inside of the bell. The outer end of the bell or cylinder is covered with one
or two toothed plates cut to resemble toothed wheels, These are held in position
by a central pin, to which a fly-nut is fixed.
When I make use of two toothed plates I fit them so that when the teeth of the
two wheels coincide with each other-one tooth being placed exactly over the other
the series of circumferential openings are then at their widest, and the divided
streams pass through such openings. When it is desired to reduce the quantity of
liquid, the outer toothed disc is slightly rotated on its centre, whereby teeth are
shifted and the openings reduced in size and the quantity of the flowing liquid
is also reduced. The delivery of the spray can thus be regulated with great
precision.
In some cases I use only one toothed disc, which is turned slightly conical, and
fits into a similarly turned conical seat in the bell. This disc is also held in its
place by a central pin, and a fly-nut; and by tightening or releasing the nut, the
disc is pressed to or, more or less, separated from its seat, and thereby the quantity
of the flowing liquid can be regulated at pleasure.

page_text: I, ALBERT FERDINAND LINK, of 8 Union Court Chambers, Old Broad Street, in
the City of London, Merchant, do hereby declare the nature of my said Invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The object of my invention is to effect improvements in rose-heads or nozzles for
diffusing spray, whether used in ventilating apparatus to cleanse the air from fine
dust, or in baths, or otherwise.
I construct such rose-heads or nozzles either of a bell or cylindrical form, and
usually of brass, one end of which is screwed or otherwise connected with the
supply pipe; suitable openings being provided to admit the water, or other liquid,
to the inside of the bell. The outer end of the bell or cylinder is covered with one
or two toothed plates, cut to resemble toothod wheels. These are held in position
by a central pin, to which a fly-nut is fitted.
When I make use of two toothed plates I fit them so that when the teeth of
the two wheels coincide with each other-one tooth being placed exactly over
the other the series of circumferential openings are then at their widest, and
the divided streams pass through such openings. When it is desired to reduce the
quantity of liquid, the outer toothed disc is slightly rotated on its centre, whereby
teeth are shifted and the openings reduced in size, and the quantity of the flowing
liquid is also reduced. The delivery of the spray can thus be regulated with great
precision.
In some cases I use only one toothed disc, which is turned slightly conical, and
fits into a similarly turned conical seat in the bell. This disc is also held in its
place by a central pin, and a fly-nut; and by tightening or releasing the nut, the
disc is pressed to, or, more or less, separated from its seat, and thereby the quantity
of the flowing liquid can be regulated at pleasure.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a sectional elevation, Fig. 2 is an end view of the same, shewing one
method of carrying out my invention, and Fig. 3 is a sectional elevation showing
another method. a is the body of the bell-shaped casting, having a spindle b cast
therewith. c is a female screw for attaching the same to the supply pipe. d d are
holes or slots for admitting the fluid to the body of the diffuser. In Figs. 1 and 2
When the teeth of these wheels
the disc e supports two toothed wheels f and g.
coincide with each other the small ports for the exit of the spray are fully opened:
when they do not coincide-as shown in Fig. 2-the ports h h are partially open;
and by regulating the position of the teeth relatively to each other, the openings
can be adjusted to the desired issue of spray.
In Fig. 3 the disc e is so formed as itself to form the cover, and its position on
the spindle b regulates the extent of the opening h; which may be a simple annular

page_text: opening, or a corrugated, toothed or serrated opening, as desired. is a fly-nut
fitting the screw k for regulating and fixing the position of the cover or covers.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The manufacture and use of rose-heads or nozzles for the diffusion of spray
having two toothed wheels f and g superposed and concentrically mounted,
regulated, and operating substantially as herein before described and shewn in
Figs. 1 and 2 of the drawings.
2. The manufacture and use of rose-heads or nozzles for the purposes aforesaid
having a conical, toothed or serrated disc e mounted regulated and operating sub-
stantially as herein before described and shewn on the drawings.
3. The general combination and arrangement of the several and respective parts,
together forming my improvements in rose-heads or nozzles for the diffusion of
spray, substantially as herein before described and shewn on the drawings.
