Improvements in Sprinklers or Spray-producers.
We, SAMUEL MORRIS, of High Street, Chorley, in the County of Lancaster, Solicitor,
and GEORGE BELL HAMER, of 100, Bradford Street, Bolton, in the aforesaid county,
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:-that is to say :-
It relates to the production of means for sprinkling or for producing sprays of
liquids on passing through a hose-pipe, main or the like, the same being of such a
construction that the condition of said spray or issuing liquid may be regulated to be
in a more or less finely divided state as may be required.
To attain this object we follow the method of construction in the production of
these means as is hereinafter set forth and as illustrated by the accompanying sheet
of drawings in which :-
Fig. 1 is a sectional elevation of a rose or device for application to the end of a
hose-pipe, main or the like the outer end of said rose having a series of concentric or
spiral slits or openings made in it for the passage of the liquid as hereinafter
explained.
Fig. 2 is a view of the rose shown by Fig. 1 as seen from above.
Fig. 3 is a similar view to Fig. 1 but shows a rose having a series of concentric
rings or annular pieces with their intervening spaces instead of the openings as shown
by Figs. 1 and 2.
Fig. 3 shows a modification in the formation of the parts shown by Fig. 3.
Figs. 4 and 5 are part sectional views showing roses wherein the outer orifices are
of an elongated instead of circular or spiral formatiou.
Fig. 6 is a view of the rose shown by Fig. as seen from above.
Figs. 7 and 8 are sectional side elevation and end view of a modification in the
formation of the rose as hereinafter described.
Figs. 9, 10, 11, 12, and 13 are drawings in detail illustrating certain formations
hereinafter referred to.
Similar letters and figures of reference indicate similar parts throughout the several
views.
In connection with means for producing sprays of liquid we have found that by
the liquid desired thus to be controlled, being forced through a narrow opening to
impinge upon the air, this latter splits it up into a more or less finely divided state
proportionate with the lesser or greater width of the orifice through which it is thus
being passed or emerges, and to produce these narrow openings or orifices in
accordance with one arrangement we construct the outer end a of the rose 6 of sheet
metal either by the process known as stamping or pressing or otherwise and in this
outer end we form spiral or concentric openings as shown by Figs. 1 and 2 while to
enable the conditions of the spray to be varied we have this said part a loose or
detachable, its fixing on the end of the part b being secured by the cap c.
In another arrangement we have a series of rings d as shown by Fig. 3 held in
position by a bolt e which by being screwed into the cross piece f or tightened up by

page_text: its nut causes the said rings d to approach each other more closely, the reversing of
the motion of said bolt having the reverse effect, thus the variations in the conditions
of the spray produced may be effected without detaching any part, or the form of the
rings d¹ shown by Fig. 3 may be used instead of those shown by Fig. 3 in which
case they are held in one direction by the screw e while they rest upon the stepped
cross y for support.
Instead of the circular or spiral openings, elongated orifices may be used and these
we produce by the employment of a series of parallel bars or cross pieces g as shown
by Figs. 4 to 11 inclusive. In the arrangement shown by Fig. 4 the bars g form a
convex outer surface and in that shown by Fig. 5 they form one of concave shape,
while the caps c secure them in these respective positions.
In the arrangement shown by Figs. 7, 8, 9, 10 and 11 the short bars form a
quadrant and are arranged relatively with each other as shown either by being passed
through holes bored in the edges h as shown by Fig. 8, or by being placed within the
grooves in which they are held by a soft metal, cement or like binding substance
being poured or run therein as shown by Fig. 10. Or these bars g may be embedded
in india-rubber, gutta-percha or the like, in which they are held by a cap or cover m
as shown by Figs. 9 and 11 and this arrangement, since the cover m is detachable,
affords better facilities for adjusting and regulating the respective and relative
positions of the bars g to alter the conditions of the spray as desired.
Instead of the cross bars g being employed the form of rose shown by Figs. 12
and 13 may be used and the outer orifice enclosed or nearly so by a wedge shaped
cover p, the outer walls or edges h h being made to conform to this wedge shape as
shown by Fig. 12 in order that on said cover p being placed into position narrow
interstices are left on each side of it between said edges h h. The width of these
interstices may be diminished or increased by forcing the cover p further down between
the edges h h or allowing it to rise out of same by the resilience of the india-rubber
seating s (Fig. 13) against which it is held and pressed by its retaining screws was
will be understood and this formation enables the regulating of the spray to be very
readily carried into effect.
Having now particularly described and ascertained the nature of our said invention,
and in what manner the same is to be performed, we declare that what we claim is :-
1. A spray-producer having its outer orifices formed spirally or in a series of circles
and otherwise constructed substantially as herein specified.
2. A spray-producer having its outer orifices formed by a series of bars the same
being held in position substantially as herein set forth.
3. A spray-producer having its outer end of quadrant shape and the orifices at such
end formed substantially as herein specified.
4. A spray-producer having its outer end or opening partially filled by a covering
piece which is formed to leave interstices for the passage of liquid desired to issue in
a spray substantially as herein specified.
5. A spray-producer constructed and arranged to operate substantially as herein
specified.
