2 Claims.

by projecting a water stream through the center of the bristles.

A further object of this invention is to provide a brush structure wherein the bristles are of endless construction, with the bristles arranged in angularly related bristle groups and with the bristles and the brush head, including the handle, formed out of plastic or other similar material.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specificaticn, and then more particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a detailed side elevaticn partly broken away and in section of a brush constructed according to an embodiment of this invention.

Figure 2 is a detailed end elevation partly broken away of the brush.

Figure 3 is a detailed side elevation partly in section of one of the bristle groups.

Figure 4 is a fragmentary plan view showing one of the bristle groups.

Figure 5 is a fragmentary sectional view taken on the line 55 of Figure 3.

Referring to the drawing, the numeral o designates generally a brush. handle which is formed at its inner or rear end With an opening l3. The handle o has secured to or formed integral with the forward end thereof a transversely arcuate brush head ll having a concave upper side l2.

A plurality of groups of bristles generally designated as l4 are secured to and extend from the concave inner side of the brush head l, and each bristle group is formed of a central ircular member l5 With crossed angularly related bristle members IG and [1. It will be readily apparent that the formation need not be confined to cir cular and that oval or other shapes may be utilized, the important feature being to maintain an axial opening so that all accumulated matter can readily be flushed off the brush by directing a stream of water therethrough and thus have a sanitary, clean center. An oval shape would be an advantage (for example, in cleaning milk bottles and the like).

The inner or rear portions of the bristle members l5, l6 and ll are secured to or embedded within the head l l. The axes of the bristle members I5, l6 and l1 are disposed in a plana parallel to the axis of the concave outer side IZ of the head Il. These bristle members I5, 16 and l1 may be secured together at their crossing points, as indicated at l8, or if desired the bristle members may be unsecured one relative to the other so that the bristle members may have independent movement in the use of the brush.

In the formation of the brush structure, the bristles [5, ls and l1 may be secured within the concave side l2 of the head ll at the time the plastic forming the head ll is relatively soft, or, if desired, the bristles may be cemented or otherwise firmly attached to the head ll in the concave forward side I2 thereof.

The brush is used in the conventional manner in the cleaning of dishes or other implemente, and when the brush is to be cleaned, the brush may be turned edgewise so that a stream of water may be projected axially through the bristles.

The construction and arrangement disclosed herein makes possible a thorough cleaning of all the tine surfaces when for example, using the device to clean the tines of a fork or the surfaces of a spoon. There may be as many groups of bristles as desired,

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

1. A brush comprsing a head formed with a concave forward side, a handle projecting from said head, and a series of groups of bristles carried by said head, said bristles being fixed in said concave forward side, each group of bristles being formed of three ring-shaped bristle members arranged in crossed relation the central member of each group lying in a plane perpendicular to the axis of said brush head and the outer members of each group being inclined toward and crossing each other and the central member.

2. A brush having a handle portion and elements forming a brush head secured to said handle, said elements composed of spaced groups of three continuous members arranged in crossed relation the central member of each group lying in a plane perpendicular to the axis of said brush head and the outer members of each group being inclined toward and crossing each other and the central member, to provide an axial clear space therethrough whereby waste material accumu lated on said head way be flushed off by a stream of water projected through said space.
