## Abstract

A brush curved having a brush head with a central portion from which extend two arm or wing portions. The wing portions extend away from the central portion at a separation angle of approximately 70.degree. to 90.degree., and preferably 75.degree. to 85.degree., and more preferably at an angle of 80.degree.. Extension of the wings away from a common side of the central portion forms a curved pocket or cup cleaning channel at one edge of the bristles or sponge-like material of the brush. This cleaning channel serves to funnel dirty water away from the contoured surface of an automobile being cleaned. Water is swept across the contoured surface, making drying of the contoured surface less of a chore.

## Claims

### Claim 1

A washing brush comprising:
a brush body,
a washing body secured to a bottom of said brush body,
said brush body including a central portion and two wing portions located on opposite sides of said central portion and extending away from said central portion from a common edge of said central portion,
said two wing portions with said central portion forming a collection pocket for collecting water and funnelling the water in a direction of movement of said brush body,
a water inlet to said brush body located at said edge of said central portion, said water inlet being located on and said two wing portions extending away from a same side of said central portion, and
an upper surface of said brush body including a plurality of ridges following a contour of said central portion and said two wing portions.

### Claim 2 (depends on 1)

A washing brush as claimed in claim 1, wherein said wing portions diverge from said central portion at an angle in the range of 70.degree. to 90.degree. from each other.

### Claim 3 (depends on 1)

A washing brush as claimed in claim 1, wherein a water passageway extending through said brush body, initiating at said water inlet, is reduced in diameter inside said brush body.

### Claim 4 (depends on 1)

A washing brush as claimed in claim 1, wherein said plurality of ridges are separated from each other to form a plurality of channels therebetween.

### Claim 5 (depends on 1)

A washing brush as claimed in claim 1, wherein said washing body includes a plurality of bristles.

### Claim 6 (depends on 1)

A washing brush as claimed in claim 1, wherein said washing body includes a sponge-like material.

### Claim 7

A washing brush head comprising:
a brush body including a central portion and two wing portions located on opposite sides of said central portion, said two wing portions extending from one edge of said central portion,
a water inlet to said brush body located at said one edge of said central portion, said water inlet being located on and said two wing portions extending away from a same side of said central portion,
an outlet located at a lower surface of said brush body,
a passageway formed in said brush body in communication with said water inlet and said outlet,
a diameter of said passageway being reduced between said water inlet and said outlet, and
an upper surface of said brush including a plurality of ridges following a contour of said central portion and said two wing portions.

### Claim 8 (depends on 7)

A washing brush as claimed in claim 7, wherein said plurality of ridges are separated from each other to form a plurality of channels therebetween.

### Claim 9 (depends on 7)

A washing brush head as claimed in claim 7, wherein a washing body is secured to said lower surface of said brush body.

### Claim 10 (depends on 9)

A washing brush as claimed in claim 9, wherein said washing body includes a plurality of bristles.

### Claim 11 (depends on 9)

A washing brush as claimed in claim 9, wherein said washing body includes a sponge-like material.

### Claim 12 (depends on 7)

A washing brush head as claimed in claim 7, wherein said outlet is centrally located in said lower surface of said brush body.

### Claim 13 (depends on 7)

A washing brush head as claimed in claim 7, wherein said wing portions diverge from said central portion at an angle in the range of 70.degree. to 90.degree. from each other to form a collection pocket to funnel water in a direction of movement of said brush body.
