Patentecl Dec. 9, 1947 HANDLE OPERTED BRUSHES,BRQOMS,. AN D`LIKE ARTICLES This inventioni relates to improvementsin'handie-operated brushes, broomsand like articles." It hasheretofore beenl the practice to provide on brushes, such as dust brushes or bristle brooms and' scrubbing brushes, bearing brackets 'or lugs in" which handles are mounted. Such handles were usually pivotally movable in a vertical plane inthebearing bracket about a horizontal pivot or pivots from'a position at right angles to'the head at onen side thereof to and through intermediate positions to a position at right angles to the head on the opposite side thereof. This enabled the angularity of the handle to the brush head and its bristles to be changed'and reversed so as to enable equalization of Wear of such bristles during use at two edges ofthe bristles, it being understood that constant contact of one edge of the bristles with the surface.

to be cleaned, while the handle is in one position, will cause uneven wear andan inclination of the bristles in relation to the head, and that a move-V ment of the handle will assist in avoiding such uneven wear at two of the longitudinal edges of the bristles.

One of the objects of my invention is vto provide means whereby the wear of the bristles will be equalized at all four of the edges of the brush.

Another object of my invention is to facilitate the movement of the handle to varying positions about the head of' the brush.

Still another object of my invention is to enable the projection of the brush into longl narrow spaces, within which only the narrow edge of the brush will nt and which could not otherwise be entered to the same extent with a handle-operated brush.

Another object of my invention is to provide a bearing bracket for the handle of the brush that may be turned axially about a vertical pivot on the head thereof, so that the narrow portion of the brush may be arranged parallel to the handle to enable insertion of the brush lengthwiseiinto corners and narrow spaces.

Another object of my invention is to provide an easy and quick method of reversing the position o-f the handle to oppositecsides of the brush in four handle positions, two at opposite sides of the head and two at the opposite ends thereof,

2] thus 'enabling veii'cient brushing' of'all surfaces.

Referringn'owto these drawings, and particf.

ujlarly to rFigs.` lftojS thereof, Bindicates .a brushv having bristles l'mountedin' the head 2 and operable byaconventional lon'g handle' l I'which". asLshown', isY provided 'at its bottom end with a knuckl'ecr spool 8 mounted pivot-,ally in a U,v shapedA 'bearing bracket 5 on a horizontal pivot pin 9"'and being movable to swing about said pinin a. vertical arcuate path from one side off.

said head to the otherand to project at .right anglesfrom either side of the head.. The handle is preferablyV lockable in'any suitable position for operation'fjor use at'either side of the head2 by. a thumb screw l 5'," and'this j mounting `thus ,pro-.v videsfor'the swinging 'and locking of the operat-f inghandle in suchreversed positions so astol enable equalization ofthe wear of thebristles`vv 3 tion of a screw 6 and preferably is mounted above a socketed base-plate I secured to the brush head 2 by screws 3. rJ.he bracket 5 is lockable to said base plate in four radial positions with reference to the brush head and the handle may thus be caused to project from the ends of the brush head as well as from the sides.

In all the embodiments of my invention shown, the bracket 5 comprises a U-snaped oblong member composed of a flat bottom plate I2 and two side-plates i3 and I4 extendmg vertically therefrom to form bearings for the knuckle or spool 3 to which the handle II is connected and, in accordance with my invention, the screw-pivot v6 passes vertically through the bottom plate at its central portion radially beneath the knuckle 8 and in vertical alignment with the horizontal pivot 9 and the ends of said oblong U-shaped member 5 move in a circular path about said pivot 6 and I provide in the base-plate I a series of four. depressions or notches II disposed in a circular path and adapted, during axial turning movement of the bracket, to be reached by an engaging member or members 1 carried by the Said bottom plate I2.

In the construction shown in Figs. 1 to 3, the depressions or notches are positioned at quadrant positions of the circular path, thus providing four positions in which the bearing bracket may be locked and these positions confront the two sides and the two ends of the bracket, and the pair of engaging members comprise conventional latch elements composed of a casing I6 and a springpressed plunger member I1, the construction of which is more particularly illustrated in Figs. 4 to 6.

In Figs. 4 to 6 inclusive, I have shown a modified formvof my invention in which, instead cf tne engaging members or latch members being carried by the bracket member, a series cf four latching elements, each composed of a casing land'a Spring-pressed plunger I9, are mounted in holes or sockets 20 partially formed in the base plate and partially in the head 2. The plungers extend upwardly to enter into sockets 26 formed in the bottom plate I2 of the bracket 5. As shown, eacn latching element comprises a plunger I8 mounted to slide in a casing I9 and provided at its lower end with a guide-pin 24 fixed or connected to the plunger and having a`.slidable connection with the end of the casing.- Thepin 24 has mounted thereon a spiral spring 25 arranged between the contracted bottom portion of the casing and the lower end of the plunger I8. As above indicated,

four of these spring-pressed latch-elements are arranged in the arc of a circle to confront the sides and ends of the bracket member, and said bracket is provided with sockets or depressions 25 at opposite ends of the axial swivel or pivot pin 21. In other respects the construction shown in Figs. 4 to 6 is similar to that described and illustrated in regard to Figs. 1 to 3.

In Figs. 7 to 9 I have illustrated a modified and preferred construction of my invention, in which a latching element or pawl 30 is pivotally mounted on a horizontal pivot 3| extending between the sides I3 and I4 of the bracket member 5, which is substantially similar in all respects to the brackets hereinabove described in relation to Figs. 1 to 6. This latching element has an inwardly-extending arm 32 extending across the axial pivot 4 6 and provided at its end with a toe portion 33 adapted to pass through an aperture 34 in the bottom plate l2 of the bracket 5 and to enter one of a series of four sockets or apertures composed of registering

portions

35 and 36 in the base plate I and head 2. At the opposite side of the pivot 3 I,

' the latching member is provided with an operating arm 31 extending outside the bracket 5 so as to permit foot-operation or a stepping upon the same by means of the shoe S of the operator. The latching member or pawl 3B is provided with a spring 38 which is preferably suitably fastened to the arm 31 and bears against the upper surface of the bottom plate I2 of the bracket. This construction is otherwise similar to that shown in Figs. 1 to 6 inclusive and, because of the embodiment therein of a foot-actuated latching element, provides a very handy method of changing the position of the bracket in relation to the head.

The operation of the device will be substantially obvious from the foregoing description and it will only be necessary to say that in Figs. 1 to 6 the latching elements are automatically engageable and releasable by the mere turning of the handle bracket, while in Figs. 7 to 9 the engagement is positive and is releasable by the pressure of the toe of the user on the extension portion 31 and the simultaneously turning of the handle-bracket by the use of the handle.

Having described my invention, I claim:

A handle-operated brush embodying, in combination, a brush-head member having bristles 'projecting from its lower surface and provided on its upper surface with a at faced base plate, a pivot member mounted centrally of said base plate, a handle-bracket member of U-shaped com formation mounted to swivel on said pivot member in a completely circular path relative to said base plate and having a flat bottom plate movable, during said swiveling of said bracket member, in parallelism with and closely adjacent to said flat base plate, a handle mounted in the side walls of said U-shaped bracket, a manually releasable latching element mounted on one .of said adjacent plates and latch sockets in the other plate said latching element in latched position directly engaging said bottom plate said socket being arranged n quadrant positions in an arc of a circle surrounding said pivot member, and independent spring means for moving said latching element into latching position whereby a readily releasable and rugged latching construction capable of roughusage is provided.
