. BRUSH.

Application filed June 20, 1925.,5Serial No. 38,581.

My invention relates more especially to that class of'brushes that are adapted for use in relnoving dust and dirt, as'ashes, from floors, hearths and other similar surfaces, and an object of my invention, amongothers, is theproduction of a. brush of this type that shall be extremely simple in construction and that may, therefore, be produced at a minimum cost, one that is particularly efficient for the ,purpose for which it is designed, and one the construction of which shall be such as to produce a brush having a very .neat appearance.

' One form of abrush embodying my inventionwand in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which Figure 1 is a side view of brush embodying my invention.

Figure 2 is an isometric View of my 1m proved brush with the handle removed.

Figure 3 is a similar view showing the construction and application of the cover sleeve,

the brush being broken off.

Figure 4 is a detail view of that end of the handle to which the brush is secured.

In the accompanying drawings the numeral 5 indicates the handle of my improved brush which handle may be composed of any suitable material, as wood, with a. hole extending inwardly at the end thereof and with a ferrule 6 applied to such end in any suitable manner. This end of the handle and the end of the ferrule are provided with a crosswise groove 7rpreferably formed on the arc of a circle.

The brush usuallycomprises a core 8 of twisted wire to which bristles 9 are secured in the twisting operation, in a manner that will be readily understood, this core being bent into a frame-like structure of oblong shape, the ends of which frame are rounded. The ends 10 of the core are bent at substantially right angles to the main part of the frame and are forced into the hole in the end of the handle, said hole being enough smaller than the ends 10 to retain the latter securely in place.

The ends of the brush 11, that is composed of the bristles above described, are cut off, preferably square with the core, as shown in Figures 1 and 2, thereby leaving a space 12 between the opposite ends of the brush, these squared ends being located at some distance from the handle .5, and the wire core between these squared ends being bare and devoid of bristles.

A retaining sleeve 13, in the form of :a tube, is made from sheet metal of a length substantially that of the width of the space 12, this sleeve being preferably of rounded form on its upper side and theedges 14 are broughttogether at the under side thereof, that is, on that side toward the bottomgpor:

of construction these edges being located at an angle to each other, and as .shown :in

is not absolutely essential. '.A hole 16 is formed through the top side of the sleeve at about its lengthwise center and the ends 10 of the wire core are extended through this hole and into the hole hereinbefore described, as being formed in the end of the handle, and when such ends were secured. in the hole in the handle the rounded part of the sleeve will rest snugly in the recess 7, and when such ends are inserted through the hole 16 said ends are securely, held to maintain the shape of the frame. 7

In the preferred form of construction the ends 10 of the wire core are inserted throu h the holes 16 before the sleeve is finally bent into tubular form, this latter operation taking place just before the ends 10 are inserted in the hole in the end of the handle.

It will be seen that a brush thus constructed is very simple in construction, light, durable, and extremely neat in appearance, and the cover sleeve effectually obscures the otherwise bare portionv of the twisted wire core and also serves as a shield to prevent marring of articles structures, the sleeve being smooth as compared with the twisted wire core.

tion 15 of the brush, in a convenient form Figure of the drawings, altho this form V of furniture or other A brush frame of this character is naturally more or less flexible, and this flexibility would tend in use to loosen the ends contained in the handle 5, and the sleeve 13, is therefore, provided for the purpose of strengthening the brush ends and imparting rigidity to them, whereby this springing action is reduced to a minimum and looseni of the ends of the brush in the handle by such action is greatly lessened.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the in- 'vention may be carried out by other means 5 i and applied to uses other set out.

1. A brush comprising a core having brush material secured thereto and bent into a a frame-like form with the ends outturned at an angle to the main part of the frame, said core being devoid of bristles for a distance on both sides of said outturned ends, and a cover sleeve enveloping said bared portion of the core and having a hole opening laterally at substantially the lengthwise center thereof through which said bent ends extend, whereby said ends are held against separation and the form of the frame and rigidity thereof is preserved.

2. A brush comprising a core having brush material secured thereto and bent into a frame-like form with the ends outturned at an angle to the main part of the frame, said core being devoid of bristles than those above for a distance on both sides of said outturned ends, a cover sleeve enveloping said bare portion of the core and having a hole opening laterally at substantially the lengthwise center thereof through which said bent ends extend thereby preserving the rigidity of said frame, and a handle having a hole in its end within which said bent ends are secured. i

3. A brush comprising a core having brush material secured thereto and bent into a frame-like form with the ends outturned at an angle to the main part of the frame, said core being devoid of bristles for a distance on both sides of said outturned ends, a cover sleeve enveloping said bare portion of the core and having a hole opening laterally at substantially the lengthwise center thereof through which said bent ends extend thereby preserving the rigidit of said frame, and a handle having a ho e in its end within which said bent ends are secured, said handle also having a crosswise groove within which said sleeve is seated.
