iaATH SPRAY BRUSH.: i

Application ined March 31, 1925. serial No. 19,708.`

This invention relates to bath g spray brushes andfhas for its principallobject the construction of' an improved brush of the fountain type in which the paths of the .jets of liquid en'ianating frointhe perforations in a central reservoir are intersected by the inner layer or .layers of the filamentous por tion ofthe brush `so that At-lie `jets-are trans formed into nuineious .films upon the sur- 1ffaces of the-filaments, avoiding the direct impino'einent of the jets upon the body to which the brushv is applied, thereby'prevent-y ing splashing, fand at the -same time con-lr stantly flushing the filamentous portionand contacting surface of :said filamentous portion and the body, where thev cleansing acj tioiristaking place.

Another object ofthefinventionfis vto conother, the innermost layer assuming a conical shape, a similar shapegbeingyalso 'assuined by the successive layers in a progressively less degree until the outer layer is reached, the latte-r being substantially cylindrical and giving conventional shape to the brush.

Other objects of the invention will appear as the description of a preferred einbodiment thereof proceeds.

In the drawings Figure l is a view in elevation showing my improved bath spray brush.

Figure 2 is a diainetrical section on the line 2-27 Figure l.. Y n

Figure 3 is a section taken along the line 8-3 of Figure 2. i

Referring now in detail to the several fig' ures, the numeral l represents a reservoir 4F or rose which is preferably metallic and provided with atubular portion 2 'intended to be connected by a flexible tubing 8 or other suitable means with a. source of water, preferably under'pressure. The face of the reservoir is perforated as indicated att. The reservoir is surrounded by a strip 5 of rubber or other material,`preferably elastic1 wound helio-ally to form several layers as indicated at 6 in Figure 2. vSlits are made in one longitudinal edge of the strip 5 to form bristles or filaments 7. The perforated l .sion around the periphery of the reservoir "fbeing supplied without Waste between the struct'a brush in which a central reservoirv the helical winding' stand away fronieachv face of the reservoir l is bevelled vatiits edge,i

as at l0, and the strip 5 is wound under ten- .Y

with the innerends of its slits substantially in alignment with said perforated face`;,and,

1 since theslitted portion of the innermost layerfis `not undersucli restraintas the un Y slitted portion of said' layer, the filaments 7 of said innermost layer .will be Adrawn iinwardly over the bevelledvedge lO ofthe Vperf forated, faceof the reservoir fandbe caused 'to assuniea conical form as shownat 8 yin,.-

F-igure 3. Under the saine or a less degree of tension as may bepfound desirable7 the t- Succeeding layersare`wound so thattheilament 7 thereof will assume lessdegrees vofv conioity until the outer layerl is reached wherein both the filaments andftlie unslitted portion will be substantially cylindrical,l that i is to say,` normal to a plane perpen'dicularto the axis of the brush. v ,l i' Any desired means maybe employ-ed for securing the rubber-strip to the, peripheral j edge of the reservoir, inthe present -in-V stancesaid reservoirlbeing shown as forii'ied with'a shallow annularfchannel 9 intorwhicli the upper edge/'of the -unslitted .portion of i' the" rubber sinltsund'ei" the tension of winding, automatically interlocking itself lwith said reservoir sufficiently to avoid subse-Iv quent displacement. Any suitable cement may be applied to the'unslitted portion of said rubber strip to promote adhesion of' the successivevlayers and it in ay be desirable y to apply a vulcanizing cement thereto and to vulcanize the brush so thatthe inner ends of the helical windings become nnitarilyV massed. This may be done by inimersing the' brush in boiling water for a Vsuitable length of time. y

'A brush formed according to thev princi-y ples of the present invention has the fol` lowing advantages; the inneimostlayer of filamentous material intersects the paths of thejets emanating from the perforat-ons l. It thus transforms the jets into'films which -flow along the rubber filaments and are de-` livered to the body as films and not as jets, thereby avoiding splashing.` The separated relationship assumed by the successive layers of filaments assures that thefbrush may be easily dried and maintained in sanitary condition and the decreasing` coiiicity of the several layers, and Yparticularly the cylindrical forni ofthe outermost'layer, gives to the brush a conventional shape' and causes'v it Vto have an appearance oi great fullness,

notwithstanding the` use of Va minimum length of the rubber strip.
