Nov. 1, 1938. s. ZBARSKY BRUSH FOR VENETIAN BLINDS Filed Dec. 7, 1957 I IN VENTOR. SAM ZBARSKY Patented Nov. 1, 1938 UNI-TED STATES PATENT oF icr:

1 Claim.

This invention relates to brushes, more particularly, to a type of brush which is essentially adapted for the cleaning of Venetian blinds and the like.

As can be easily realized, the cleaning of Venetian blinds is a diflicult arid tedious matter, particularly with the ordinary type of brush wherein it is possible only to clean a single slat at a time. It therefore becomes highly desirable to provide a brush'which is capable of cleaning a plurality of slats simultaneously. Since Venetian blinds vary in size, that is, in the spacing between the slats, it is highly desirable that a brush for this purpose be capable of not only cleaning a plurality of slats, but that it be adjustable in order to provide for the different sizes of Venetian blinds encountered on the market.

Prior brushes, such as are well known in the art, are not adapted for this purpose. For example, there has been on 'the market a brush consisting of a plurality of brushing members threaded into a hdlder; but these brushes are of such a character as not to lend themselves for the purpose of cleaning Venetian blinds because each of the members consists of a series of bristles,

and the manner in which such bristles alignthemselves would make it almost impossible to successfully and efiectively clean Venetian blinds.

Inaccordance with the present invention, I provide a brush holder consisting usually of an elongated wooden member. Said member has generally two sets of equally spaced openings adapted to temporarily receive brushing members. Each of said members consists of a core having cemented, or otherwise secured thereto, lambskin or other animal skins to form the brushing members.' Said members are mounted in the holder, being equally spaced and being parallel to each other. The parallel relationship of the brushing members throughout practically their entire length is an important feature of a brush of the type described herein.

In order to facilitate the introduction of the brushing members into the holder, and also to firmly secure them in their position, I provide a special construction involving the use of nuts which are secured in the holder and corresponding threaded members extending from the brushing members for threading the same in place.

In the accompanying drawing, constituting a part hereof, and in which like reference characters indicate like parts, I

Fig. 1 is a side elevational view of a brush made in accordance with my invention,.showing some noted from Fig. 1 that the handle is at a subof the brushing members in full and others in outline;

Fig. 2 is a vertical, cross-sectional view taken along the line 2-2 of Fig. 1; and

Fig. 3 is a view from below showing the ar- 5 rangement of two sets of equally spaced openings.

The device consists essentially of an elongated holder I having a handle 2 secured to the top thereof by dowel pins tor the like. It will be 10 stantial angle to holder l and the plane of handle 2 is within the plane of the brushing members.

A slot or groove 4 is formed along one side of holder 1 throughout substantially its entire length. Said groove,-as best shown in Fig. 2, is relatively deep and extends beyond the center line of the holder. A series of

openings

5, 6, I, 8, Sand I0, equally spaced, extend from the lower side of holder 5 through the groove 4 and a substantial distance into the body of the holder. A second set of openings of similar character, best shown in Fig.3, as openings ll, I2 and it, are equally spaced with respect to openings 5 and Ill and with respect to each other. A brush: ing member is adapted to be held in each of said openings. If a Venetian blind having a relatively wide spacing between slats is to be cleaned, then the brushing elements are inserted into openings 5, ll, l2, l3 and I0. If, on the other hand, a Venetian blind with relatively narrow spacing between slats is to be cleaned, the brushing elements are inserted into openings 5 through It), inclusive. In each case, the brushing members are equally spaced from each other.

Each of the brushing elements consists of a core It usually of wood, having a covering I5 of lambskin or the like cemented to the core M. In the free end of the coreM is a wood screw l6 having a portion ll projecting from the end of said core and provided with threads. A series of nuts I8 are inserted in groove 4' and are positioned with the openings of said nuts in alignment with the several openings 5 to I3, inclusive. Usually, the width of the groove 4 is such that the nuts l8 are held firmly in position. A strip I9 is introduced into the groove 4 and is held in place by cementing or otherwise.

From the above description it will be apparent that the brush of the present invention is simple to construct and efiective in action. There are provided a plurality of brushing members l5 which may be spaced in various ways, as desired, which are always parallel to each other, and which may therefore be effectively used for a rapid cleaning of Venetian blinds. The handle 2 fragile, easily broke. Furthermore, in such construction,a series of bristles were formed around the core which flared outwardly and which were capable of exerting a brushing effect only on the end and not on the sides thereof.

I am also aware of a proposed construction of a brush in which the brushing element consisted to hold the bristles in place.

of .a set of bristles having a piece of wire or the like spirally wrapped around the end thereof in such a manner as to form a threaded end. Said end was intended to be introduced into a similarly threaded holder. However, this was quite unsatisfactory because it was almost impossible to correctly space the convolutions of the wire and it was difficult to cause the wire Furthermore, in use, the wire was apt to be displaced, making it impossible to insert the brushing element into the holder.

Although I have described my invention setting forth a single embodiment thereof, it is quite apparent that various changes may be made in the details of construction of brushes within the scope of my invention. For example, instead ofit being essential that there be a core and that the brushing elements be parallel to each other. In the specific example, I have described two sets of equally spaced openings having five and six openings, respectively, in said sets. The exr a number of openingsis not of importance and, therefore, the number of openings in each set may be varied. If desired, more than two sets of openings may be provided. The groove may be varied considerably in its characteristics, as, for example, I may form a series of small grooves, each of which is capable of holding one or more of the nuts. In place of the strip I9, I may introduce plastic material which will harden in place and hold the nuts in their proper relation. Instead of the materials shown and described, other materials adapted for the purpose may be substituted. These and other changes in the details of construction of the present invention may be made, and the invention is not to be limited except by the character of the claim appended hereto.

member held centrally within and projecting from one end of said core and a nut in each of said openings into which said threaded member is adapted to be held.
