IMPROVEMENTS IN SPRAY DIFFUSERS
Year: 1884

page_text: I HERMANN GUMTOW of Berlin in the Empire of Germany Engineer do hereby
declare the nature of my said invention for "IMPROVEMENTS IN SPRAY DIFFUSERS
to be as follows:-
The object of my invention is to effect improvements in the construction of spray
diffusers.
In carrying out my invention I fit an enlarged chamber to the inlet tube, and at
the outer end of this chamber I screw a circular diaphragm, having two perforations
through the same, terminating with two tubes or nozzles. The holes in and through
the tubes are tapered, and are also inclined towards each other in such a manner
that lines drawn through their axes would meet at a point a short distance from
their outer ends. An elastic ring is placed between the flange of the diaphragm
and that of the chamber, to form a watertight joint. A thin hollow cylinder is
fitted to the diaphragm, or formed in one therewith, surrounding the nozzles, and
forming a directing tube to the spray diffuser.
By my said invention the complete diffusion of the spray is effected in a more
satisfactory and efficient manner than hitherto has been the case with the ordinary
forms of spray diffusers.

page_text: I HERMANN GUṀTow of Berlin in the Empire of Germany Engineer do hereby
declare the nature of my invention for IMPROVEMENTS IN SPRAY DIFFUSERS 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 the construction of Spray
Diffusers.
In carrying out my invention I fit an enlarged chamber to the inlet tube, and at
the outer end of this Chamber I screw a circular diaphragm, having two perforations
through the same, terminating with two tubes or nozzles. The holes in and through
the tubes are tapered, and are also inclined towards each other in such a manner
that lines drawn through their axes would meet at a point a short distance from
their outer ends. An elastic ring is placed between the flange of the diaphragm
and that of the chamber, to form a watertight joint, A thin hollow cylinder is
fitted to the diaphragm, or formed in one therewith, surrounding the nozzles, and
forming a directing tube to the Spray diffuser.
By my said invention the complete diffusion of the spray is effected in a more
satisfactory and efficient manner than hitherto has been the case with the ordinary
forms of spray diffusers.
And in order that my said invention may be clearly understood, reference is
hereby made to the accompanying drawings, in which similar letters of reference
indicate corresponding parts.
Fig. 1 is a sectional elevation of my improved diffuser. Fig 2 is an external view
of the same. Fig 3 is a section on the line y of Fig. 1, and Fig 4 is a view of the
underside of Fig 2. a is the inlet tube, b is an enlarged chamber fitted to the inlet
tube a disa thin hollow cylinder, one end of which is furnished with a diaphragm,
which screws into b as shewn. In this diaphragm are the two tapered tubes f. ƒ.
which convey the spray from 6 into the cylinder d, as shewn, from whence it is
projected in radiating lines. c is a collar of India rubber or other elastic material, to
form a water tight joint.
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 construction of apparatus for diffusing water spray having two or more
tubes or channels arranged and operating substantially, as and for the purpose
herein before described and shewn in the drawings.
2. The combination and arrangement of the several and respective parts together
forming myi mprovements in spray diffusers, substantially as hereinbefore described
and shewn in the drawings.
