UNITED STATES PATENT OFFICE.

CASSIUS E. GAZEL AND JOHN W. L E CRAW, OF CINCINNATI, OHIO.

BRUSH.

T 0 all whom it may concern:

Be it known that we, CAssIUs E. CAZEL and JOHN W. Lu CRAW, citizens of the United States, residing at Cincinnati, n the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Brushes; and we do declare the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in brushes and brooms, and it has for its object to provide a. device of this class provided with a novel head which is of such construction that it will permit the bristles to be readily and easily replaced should they become worn, novel retaining means being employed to permit such replacement.

Another object of the invention is to provide a simple and effective brush which 1s of such construction that it will prevent the bristles from falling or slipping out as they ordinarily do; one which is exceedingly strong, durable, light in weight, and inexpensive to both the manufacturer and the user.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is an elevational view of a brush constructed in accordance with our invention.

Fig. 2 is a view taken on the line 2-2 of Fig. 1, looking in the direction of the arrows.

,Fig. 3 is a central longitudinal sectional view of the brush disclosing the novel bristle retaining means.

Fig. 4 is a section taken on the line 4--4 of Fig. 1.

The novelty of our brush construction resides in the formation of the head thereof which is channel-shaped in cross-section so as to permit the bristles to be folded upon themselves and seated in the channel. They are then'held in position by means of a spacing block and wire, which is so bent that it prevents all possibility of the bristles becoming displaced from the channel.

Referring to the drawings where n we have shown the preferred embodiment of our in Specification of Letters Patent. Patented Apr. 12, 1921. Application filed July 1, 1920. Serial No. 393,249.

vention, the numeral 1 designates a metal plate bent to form a channel which is closed at one end as shown at 2. Disposed in the channel and spaced from the inner walls thereof is a strip of wood 3 to be known as a spacing block. Seated on the upper edge of this block is a piece of wire 4, which is of a greater length than the block*thus permitting its ends to extend beyond the ends of the block. Seated in the channel and folded over the wire and block is a plurality of bristles 5 which are prevented from endwlse dlsplacement by means of the extended portions of the wire which are bent to form hooks 6 which surround the endmost bristles in the manner clearly shown in Fig. 3. Passing through the sides of the channel and extending into the block 3 are a plurallty of nails or other suitable retaining members 7 which serve to bind the bristles tightly between the walls of the channel and the opposite sides of the spacing block. With this construction it will be seen that when it is desired to replace the bristles, this may be done by simply removing the fastening members 7, whereby the spacing block and parts which it carries may be readily removed from the channel.

Any suitable type of handle 8 may be employed in connection with ahead of the foregoing construction. As shown this handle is of tubular formation and is formed by extending the channel member in the manner shown.

A brush constructed in accordance with our invention will be found extremely useful in that it will be possible to easily and readily remove the old worn bristles and re place them with new bristles. The brush is extremely light and is strong, durable, and exceedingly inexpensive to both the manufacturer and the user.

A careful, consideration of the foregoing description taken in connection with the accompanying drawings will enable persons skilled in the art to which this invention relates, to obtain a thorough understanding of the construction thereof. In view of this, further detailed description is deemed unnecessary. i

We claim:

A brush head comprising a member of channel-shaped cross-section, a spacing block disposed in said member and spaced from the inner walls thereof. a piece of wire resting on the inner edge of the block,

and extending beyond the ends thereof, a plurality of bristles folded over said Wire and block, the folds of the bristles being seated in the channel, the opposite ends of the aforesaid Wire being bent laterally and then inwardly toward each other around the end-most bristles, thus preventing endwise displacement of the bristles, and fastenings passing through the member and into the block, binding the bristles between the block 10 and member.
