UNITED STATES HENRY CAVE, 0F SPRINGFIELD, MASSACHUSETTS.

BRU'SI-I OR THE LIKE.

Application filed March 7, 1923.

To all whom it may 0011061 11,:

Be it known that I, HENRY GAVE, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Brushes or the like, of which the following is a specification.

This invention relates to improvements in brushes, polishers or the like, and, more particularly, to combination articles of this general nature having two or more kinds of elements, which may be used for performing different classes of service.

The invention, while capable of general application, finds one advantageous use as a floor brush and, for such use, two brushing elements are provided, one of which is much stiffer than the other and is designed forremoving threads, or any other material having a tendency to cling to a rug or carpet,the other brushing element being intended for ordinary use.

The broad object of this invention is to provide a combination article of the general class described with two or more kinds of elements and a mounting for them in a suitable frame so that either one thereof may be brought into position for action, when and as desired.

A further object of the invention is to provide an article of the class described, which has a handle or frame enabling it to be pushed or pulled over the floor, or any other surface, together with a mounting of the elements in the handle or frame in such a manner that one element will be brought into position for service by a push or pull on the handle and so that the other element will be brought into service by a movement of the handle in a reverse direction.

Other objects relate to improvements in the construction, arrangement and disposi tion of parts as will appear in the following description and the illustrative embodiment of the invention in the accompanying drawings, in which,-

Fig. 1 is a side elevational view showing a brush embodying the invention;

Fig. 2 is a fragmentary plan view thereof, the brush being indicated merely in conventional form; and

Fig. 3 is a fragmentary View taken similarly to Fig. 1 and showing the brushing elements reversed.

Referring to these drawings; the invention is shown as embodied in a brush, suit- Serial No. 623,556.

able for household use and intended to be pushed or pulled over the floor. For this particular embodiment, the combination article referred to is a double brush, or a brush with dual brushing elements, one of which is somewhat stiffer than the other, or is otherwise differently constituted, to enable it to perform a different class of work. As shown, the brush comprises bristles 1 which are secured to a core 2, such as a twisted wire core,the bristles being secured in place between the twisted wires. As a simple expedient for obtaining dual brushing elements with one core and one set of bristles, the periphery of the brush is made eccentric to the core. This may be done in any suitable way, as by trimming the bristles after the brush has been made up or by arranging the bristles during the process of making the brush. The result, in any event, is the production of dual brushing elements, consisting of a group of relatively long bristles b and a group of shorter and therefore stiffer bristles 7).

While the brush is used as an illustrative example, other articles of a more or less analogous nature may, obviously, be equally well used in its place. Also the dual brushing elements may be formed in various other ways and do not necessarily need to be formed from the same set of bristles. The main essential is a combination article having at least two elements intended for different classes of work.

Such an article, whatever its character, is mounted in a suitable frame in such a manner that any element can be brought into play, when desired. Preferably, also this object is accomplished with a minimum of effort on the part of the operator and desirably is accomplished automatically on a reverse movement of the frame. As shown, the brush is pivotally mounted in a suitable frame 5, which may be substantially forkshaped and this frame is provided with any suitable sort of handle, such as the handle 8, centrally disposed thereon. As a simple expedient, the two wires of the twisted wire core 2 are separated at each end of the core and one of the wires, as 3, is used for the shaft or pivot, for the brush,pass ing through an opening in a side arm of frame 5. The other wire, as 4:, is disposed outside the side arm in such a way that it is free to swing through a substantial angle, such as an angle of 180 degrees. This wire scribed are given primarily as illustrative examples although they are in'a measure at present preferred.

In use, the brush is pushed or pulled over the floor'by 'the"handle 8. Assuming that 'the'handle" 8 is pushed in the direction illustrated in Fig. 1, the brush may turn ;in frame 5 until wire 4 abuts lugs 6. This causes the longer set '01? bristles" b to be broughtinto position for service and this set'of bristles is usually used for ordinary service." 1"lo\vever,-if threadsgor any other material'having a tendency to cling to the carpet or' rug,- are encountered, the move ment of thebrush is reversed. This reversal *m a'y be efFe cted-by pulling on handle 8 or by swin in the latter in a counterc'loclnvise direction from the position shown in Fig. l to that shown in Fig. 3 and then pushing on the'ha'ndle. In any event; such a reversal "causesthebru'sh to turn in the frame until wire 4 abuts stops '7, Wherebythe shorterand stifferbristles' b are brought into position for service.

Theinventionhasbeen disclosed herein,

in an embodiment atpresentpreferred for illustrative purposes,- but tl1e*scope"of the invention is defined by the appended claims rather than-bythe-foregoing description.

What I claim is: 1. The combination with a frame. of a substantially cylindrical brush, a core therefordisposed eccentrically of the brush and mounted for turning movement in said frame, and means for limiting the relative turning movement of said core and frame. 2. 'The"combin-ation with a'fame} of a Z substantially cylindrical brush, a core there- "for disposedeccentrically of the brush and" comprising a pair of twisted Wires] which are separate'dat the ends of the'core, one of said"Wiresbeingfmounted for turning movement in said frame; the 'other Wirecooperating"\vitl1 saidframe asfa stop for limiting the turning movement of the otlier Wire'in said frame.

3. In an article *of th'e'class" described,

companion cleaning'elementsconstructed for somewhat different classes of service, a

frame, a member rot'atab'ly 'mountedin said frame ai'id carrying salid'elem'entsg' a stop inovable witli said member, and spaced stops provided on said frame and cooperating with the firStnzi'nied stop to limit the rotation of said member on 'th'e' frame. 4
