PATENT BRUSH-HAN DLE.

SPECIFICATION forming part of Letters Patent NO. 449,478, dated March 31, 1891. Application filed .l'uly 5, 1888. Serial No. 279,011. `(No model.)

To LH wiz/om, it' may concern:

Beit known that I, MELVIN B. IIINDS, a citizen of the United States, and a resident of Everett,in the county of Middlesex and State of Massachusetts, have invented new and useful Improvemcn ts in Brush-Handles, of which the following, taken in connection with the accompanying drawings, is a specification.

rlhis invention relates to improvements on brush-handles, and particularly on improvements on the patent granted August 19, 1879, No. 218,743, to Aaron J. Hinds for clamp for securing brush-handles, of which patent and invention I am now sole owner.

My present invention is carried out as follows, reference being had to the accompanying drawings, wherein- Figure l represents a perspective View of the improved clamp-plate adapted to be secured to the brush-block. Fig. 2 represents a plan view of the said clamp-plate, shown as secured to a brush-block, and Fig. 3 represents a cross-section on the line A B shown in Fig. 2, and showing in addition a longitudinal section of a handle attached to the clamp-plate.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In brushes of the kind that are used for sweeping floors, brushing walls, or washing windows, it is very desirable that the handle should be adapted to be secured to the clampplate on the brush-block in more than one position, so that after one side of the brush has been worn that the position of the handle relative to the brush may be changed, and thus cause the lessworn portion of the brush to be utilized, by which arrangement the. life and utility of the brush are materially increased.

u a in the drawings represent the bristles, as usual, secured to the block Z).

C is the clamp-plate, made of metal, and having flange c, of suitable form to fit the block b, to which it is secured by means of screws c c c. In one piece with the flange c is cast a pair of inclined faces c c, each one being provided with a bifurcated slot c3, as shown. Between the inner ends of the faces c c is made a square or otherwise shaped opening c, through which the nut on the handle is introduced when the handle is to be secured to the brush. (l is the handle, as usual of suitable length, and to the end of such handle is secured a screw-bolt e, the innercnd of which is provided with a wood screw-thread e', that is lirmly screwed into a central longitudinal perforation in the end of the handle d, as shown in Fig. rlhat portion of the screw-holt c that projects beyond the end of the handle is provided witha machine screwthread e, as shown in said Fig. 3, and on the latter is located the screw-threaded nut e3, which is adapted to be removed through the opening c'L while engaged with the screw-bolt c, after which the nutis again inserted through the said opening c4 for the purpose of adapting the nut and handle to the opposite side of the clamp-plate C, and thereby changing the handle from the position shown by full lines tothe position indicated by dotted lines in Fig. 3.

d is a metal ferrule on the end of handle d, as usual. In securing the handle (Z to the elamp-plate G the nut ci; is introduced into it through the central opening cV1 and the machine screw portion c of the screw-bolt c placed in one of the bifureated slots c3, as shown in Fig. 3, after which the handle (Z is turned toward the right around its axis until the face c is firmly secured between the end of handle (Z and the nut e3, as shown in Fig. 3. If it is desired to remove the handle d from the brush, this can easily be done by turning it to the left until the hold of the nut c3 is loosened on the inside of clamp-plate face c, after which the nut e3 is passed out through opening c, and if the position ot' the handle relative to the brush is to be changed this can easily be done by loosening the handle from its clamping action on one of the inclined faces c, then removing the nut c3 through the opening c4 while still engaged with the part c of the bolt e, and then inserting the nut back through the opening ci, after which thc handle is tightened up against the opposite inclined face c of the plate The vinclined faces c are rectilinear, and thus provide flat surfaces for the clamping action of the inner end of the handle, which construe` tion provides for a securing of the handle more rigidly to the brush-back.

By making the inner end of the fastening- ICC bolt wood-screw threaded, as shown in Fig. 3 the said bolt can be most iirml y secured to the end of the handle d at a very low cost as compared to other means for this purpose.

Having thus fully described the nature, constructionl and operation of my invention, I Wish to secure by Letters Patent and claim- The combination, with a brush-head b and the clamp-plate C, having the central square orifice e4, the bifurcated slots c3, and the opposite rectilinearly-inclined faces c, of the screw-n ut e3, located in the clamping-plate and removable and replaceable through the said central orifice, the handle d, and the screwbolt c, having at one end the screw-thread e engaging the handle, and at the opposite end the screw-thread e engaging the nnt, substantially as described.

In testimony whereof I have signed my name to this specica-tion, in the presence of two subscribing Witnesses, on this 30th day of June, A.D. 1888.

MELVIN B. HINDS.
