WILFRED R. THORNTON, OF TORONTO, ONTARIO, CANADA SPRAYING DEVICE Application filed April 26, 1926, Serial No. 104,682. Renewed April 26, 1930.
The principal objects of the invention are, to devise a very simple and effective device for spraying water in a downward direction with a very fine atomization of the water in a confined area and which will be very applicable to shower baths but may be advantageously used in dish washing machines or the like.
The principal feature of the invention consists in the novel formation of a rotatable member supported upon a nozzle having a plurality of lateral exits, said rotatable member being rotated by the force of the discharging water which is broken up by the 1D rotation.
In the drawings, Figure l is a longitudinal mid-sectional view of a spraying device constructed in accordance with this invention.
Figure 2 is an underside plan view.
In the form of the device herein shown the water pipe 1 is provided with an end cap 2 in which a plurality of radial holes 3 are formed, which holes are arranged preferably with a slightly forward incline toward their l discharge end.
A suitable bearing, here shown in the form of a ball bearing 4 is arranged upon the shoulder 5 of the cap 2 and mounted on the bearing 4 is a ring 6 formed of sheet metal,
said ring having a plurality of forwardly extending concavely curved blades 7.
These blades are concaved on their inner sides in a transverse plane and they are also concaved in their longitudinal plane and the several blades are set in a bucket arrangement in relation to each other, the outward longitudinal edge of each blade extending beyond and spaced from the inward edge of the adjacent blade.
lVith this construction of blades the small streams of water projected from the holes 3 in an outward and angularly forward direction strike the bevelled cup-shaped inner walls of the blades 7 and cause the device to rotate rapidly upon its bearing support.
The water striking the longitudinally curved blade is carried longitudinally of the blade and directed inwardly towards the centre, the water being discharged laterally inward from the outer or forward sections of the 5 blades in a very finely broken condition and due to the high rotative speed of the blades a rotary or whirling motion is imparted to the water as it is released from the ends of the various blades.
The spray produced, centers as described and then spreads outwardly, producing a very excellent atomization and holding the spray from spreading to too wide an area.
A spray device such as described is ex tremely desirable for use in shower baths as the finely atomized water will be concentrated directly over the head of the user. The water will therefore not spread to any great extent.
Such a spray will be of distinct advantage where used over bath tubs.
What I claim as my invention is 1. A spraying device comprising a nozzle having laterally directed openings, and a rotary member encircling said nozzle and provided with a plurality of angularly set blades extending in an axial direction past said openings, the adjacent longitudinal edges of said blades being spaced radially apart in. overlapped relation, said blades being each concaved longitudinally and transversely on their inward sides.
2. A spraying device, comprising a nozzle having a plurality of laterally directed discharge orifices arranged with a forward slope, a ring journalled on said nozzle at the rear of said orifices and having a plurality of angularly set blades extending forwardly in an axial direction past said openings and having their base portions opposite the same arranged in overlapped relation, all of said blades being curved longitudinally inward at their forward ends to impart a laterally inward thrust to the water as it passes therefrom.
3. A spraying device comprising a nozzle having laterally directed discharge openings and a rotary member encircling said nozzle at the inward side of said openings and provided with a plurality of angularly set blades extending forwardly in an axial direction from the periphery thereof beyond said openings and forming a cup-shaped enclosure, each of said blades being concaved longitudinally and transversely on their inward side, the transverse pitch being arranged at a steeper angle toward the forward end thereof.
