Application md December 1o, ieee. seria; No. 679,566.

To all whom t may concern:

Be it known that we, GEORGE S. LEINER and CHARLES A. BERNsTnIN, citizens of the United States, and residents of New Rochelle, county of Westchester, and State of New York, and of the city, .l county, and

State of New York, respectively, have invented a certain new and useful Improvement in Brushes, of which the following is a specification.

The object of this invention isto provid la brush used for cleaning purposes, scrubbing, polishing surfaces, Washing of windows and the like, which will be of strong 16 and sturdy construction, capable of standing considerable hard usa e, and. which will, by reason of its construction be particularly adapted for the nature of the .work to which it may be put. f ,d

With these objects and such other objects as may hereinafter appear, we have devised the particular arrangement vof parts set forth below and pointedout in the claims appended hereto. V

Reference is to be had to the accompanying drawing, forming a part thereof in whioh- Figure 1 is a plan view of our improved brush, parts being broken away and in section, to disclose construction,

Flgure 2 is a sectional view on the line 2 2 of Figure 1, looking in the direction `of the arrows.

Throughout the various views of the drawings, similar reference characters designate similar parts.

In the accompanying drawing, 1 indicates the wire core of the brush. This is preferably construcbed of a single section of twisted wires made in the form of a continuous loop. The bristles or other material utilized 2 are secured to the wire core in a customary manner vby holding the` same between the twists of the'wire strands which make up the core 1.

At a substantially central point the'twisted wire core 1 is bent to form a. connecting bar 3 which has its end 4 permanently joined to the end `ofthe wire core as at 5 by welding or any other method. The weld is preferably formed by interlacing or overlapping the two wires from bar 3 and the two .wires from the other end of core 1, and then welding, whereby the ends are in eifect both spliced and welded, 'thus .handle connectords also apparent.

forming a union stronger than either pair of wires forming it. This forms the wire vcore as before mentioned in a continuous loop.

The clamp which receives the handle -is disclosed at 6 and kthe same is provided with a tubular portion 7 at its end through which the cross bar 3 of the wire passes.. The cross bar serves as a bearing for a clamp to be described.' The clamp is pro- .65. vided with two jaws'8 and 9 which project from Athe tubular portion 7 and which are connected by a clamping screw 10 and the linger operated nut 10 to enable them to be drawn together to clamp any ordinary wooden handle 11 between them. v

The shape or design of the twisted wire core holding the bristles or other material is so formed or constructed that the handle connector or clamp 6 is placed in such a 75 position on the brush, that it may turn over or oscillate to the opposite sideof the brush. This permits the brush to be utilized on either side without removing the handle from the clamp or handle connector.

This connector in which the handle is attached, by being able to oscillate on the axle vof the wire core, allows the brush to lie flat against any surface, regardless of the angle the handle is held, and without allowing any part or end of the wire core ofthe brush or any metal part to come in contact with the surface being cleaned or polished.

'F rom the foregoing it will be apparent 90 that the simple construction of the brush makes it a' strong and sturdy article capable of hard usage. The welded joint at 5 for the ends of the wire core work l forms said core into a continuous unbreak- '95 able loop.

The convenience of being able to `useboth top and bottom sides of the brush to advantage without removing handle from the The lower cost of manufacture is also obvious, since the component parts -of wire and bristles are twisted together in one operation, thereby forming the body, core and frame work of the brush, without the need of any binding, adhesive or otherv material, or any other operation to secure or appl the bristles to the frame ory core on whic the handle connector 6 is attached.

From the foregoing it is obvious that our 11e `invention is not to be restricted to the exact twisted together, with bristles held between v the twisted wires, the end portions of the twisted wires both being bent inwardly to-v ward thecenter of the brush, one end portion being further bent to form a bearing,

the fourends of the two wire portions being overlapped'and lwelded to form a union immediately adjacent the said be'aring, the union being at the bend connecting the bearingwith the other wire portion, a clamping element rotatably mounted on the bearing,

and a handle carried by said clamping ele-- ment. j t

2. A brush formed of wires twisted together with bristles ,permanently held between the twisted wires, the end portions of the twisted wires being bent inwardly toward the center of the brush, one of the end portions being further bent to l'orm a bearing, the four ends of the two wire portions being overlapped and welded together so that the weld is immediately adjacent the n bearing, a tubular sleeve surrounding the bearing and rotatable thereon, provided with a. pair of semi-cylindrical gripping jaws, a threaded element extending directly throughlsaid jaws about midway of their length, and` a finger operated nut cooperating with thevthreaded element for drawing the jaws together for detachably gripping a handle therebetween. i

Signed vat the city, county and State of New York, this 30th day of November, 1923.
