CMBNATION BRUSH AND SPR-AYING NOZZLE Application filed .Tune 18, 1927. Serial No. 199,816.

This invention relates to brushes and more particularly to combination brushes and spraying nozzles for cleaning purposes.

The principal object of the invention is. to provide a brush for use in combination with a spraying nozzle, which is adapted for scraping or scouring dishes, cooking utensils such as pots andv pans, and other purposes at the same time that hotsoapy Awater or simply clear hot water Aor other fluid isbeing sprayed upon the articles to be cleaned. ,e

Another object of the invention is to pro vide a device of theabovecharacter, in which the nozzle is manually adjustable relative to the brush so that the fiuid issuing from the nozzle will strike the brush when it is desired to use the'brush during spraying, or permit independent use of the nozzlefor spray-i ing.

A further object o f the invention is to provide a device of the Vabove characterof practical construction foruse yin connection with the spraying apparatus for providing hot soapy water or hot clear water disclosed in application No. 187,463,

Vith the kabove and otherobjects in view, the invention will be hereinafter fully described as illustrated in the accompanying drawings, and the novel features thereof will be c istinctly 4pointedV ont in the appended claims.

ln the drawings, similar characters o f reference indicate corresponding parts.

Figure 1 is a longitudinal sectional view of a combination brush and adjustable spraying nozzle constructed in accordance with my invention, the nozzle vbeing in its extreme inner or withdrawn position,

Fig. isa similar view, the nozzle being in its outer position,

Fig. 3 is a'plan View of the clamping collar, Fig.'4 is across sectional view taken on 'line 4-4' of Fig. 1, and

illustrates 'the brush, the bristles thereof being shown compressed together when used for scraping purposes.

Referring to the drawings, 1 represents a handle of suitable heat insulation material and light in weight preferably bakelite. The handle is provided with a bore 2 and a slightly smaller bore 3 thereby leaving an inter` mediate annular shoulder 4. Fixed in the lower end of the handle is a metallic bushing 5, which is threaded internally at 6 for receiving a plug 7 This ,plug is internally threaded atS-for screwingupon the straight threaded end 9 of a circular wedge member 10, which is adapted to be drawn into a ferrule 11 for securely holding therein bristles of wire or other suitable material toform a' hollow brush 12. The circular wedge member 10 is provided with a central longitudinal bore 13, in which is slidably mounted a nozzle 14 of tubular forinhaving a removablel tip 15, provided with oppositely tapering openings 16 and 17. Aplug` 18 is fixed .in

the nozzle 14 and is provided with suitable. inclined grooves indicated by 19, which with the opposite openings 16 and 17 of the tip 15 give the fluid passing through said nozzle a whirling motion. Y Y

At the inner end of the nozzle 14is a flange 20, which is adapted to slide in the bore 2 and engage the annular shoulder 4 and the bushing 5 for limiting the longitudinal movement of said nozzle. Fixed into theflanged end of the nozzle 14 is avcylindrical wedge member 21, which isvthreaded at 22 for receiving a nut 23 andis thereby drawn into a sleeve 24 for securely holding the inner end of a rubber tube 25. A flattened or nut portion 26 of the cylindrical wedge member 21 is provided for the application of a wrench. In order to loch the nozzle 14 in any desired position, a metallic bushing 27 is iXed in the upper end of the handle 1 andthrough an opening 28 of said bushing passes the rubber tube 25. AThe bushing 27 bored at 29 to provide space for asplit collar 30 of spring` material, which encircles the rubber tube 25 and is adapted Yto grip the same. The bushing 27 rests upon an annular shoulder731 ,at the lower end of the bushing `27 ,and its upper end is bevelled as indicated at 32. A locking nut 33 isprovided with an opening 34 for receiving the rubber tube 25, and the neck 35 thereof is threaded at 36 for entering the threaded bore 37 of the bushing 27'. The inner end of the opening34of the locking nut 33 is tapered, as indicated at 38, for fitting over Wedge member 39 for holding said tube in a sleeve 40 by the use of a nut 4l. The outer end of the cylindrical wedge member 39 terminates in a tapering head 42, which provides a shoulder 43 for a union nut 44 adapted to be secured tofthe threaded outlet` of the spraying apparatus.

In practice, the nozzle 14 is at rst in the withdrawn position and locked as'shown in Figure 1, and hot soapy water is permitted to pass through the brush 12.- When said nozzle is in its withdrawn position,the hot soapy water, due to v,its whirling motion and the spreading there-of, vstrikes the inner side of the bristles of the brush l2, and the brush may be manipulated by means of the handle l to serve for sci'apingarticles'to be cleaned while hot soapy wateris flowing upon said articles. rl`he ends of the bristles of the brush or the'outer sides of the bristles of the brush may be used for scraping purposes, or the bristles atfthe opposite sides of the brush may beipressed together by `pressure upon the handle, as shown in Fig. 5, when the brush is so used for scraping purposes. The scraping action of the brush will loosenany clinging particles from the articles being cleaned and diflicult to remove, and then the locking nut 33 may be rotated to release the nozzle, and the nozzle adjusted to its outery position shown in Fig. 2. The spraying apparatus, to which this brush is connected, is now adjusted to provide simply clean hot water, and when the outer end of the nozzle is even with and clear of the ends of the bristles of the brush, the clean hot water will be sprayed upon the articlesbeing cleaned for rinsing the same.

From the drawings and description, it is l readily seen that this brush is practical in construction and well adapted for the purposes intended. It will be 'understood that minor changes in the details of construction may be made within the scope of the claims.
