lureutor Julian M. Ines llllllllllllll Patented June 26, 1951 UNITED STATES PATENT OFFICE SUCTION BRUSH FOR VENETIAN BLINDS AND THE Julian M. Ines, Goshen, N. H. Application December 17, 1946, Serial No. 716,717

1 Claim.

My invention relates tobrushes for cleaning the slats of Venetian blinds, and the like, and is designed as an improvement over the brush of my U. S. Letters Patent No. 2,487,444, dated November 8, 1949.

The primary object of the instant invention is to provide a brush for the purpose above indicated which is simplified in construction, as compared with that of my patent noted in the foregoing, adapted for quick and easier replacement of the brush element proper, and is less expensive to manufacture.

To the accomplishment of the above, and subordinate objects presently appearing, a preferred embodiment of my invention has been illustrated in the accompanying drawing, set forth in detail in the succeeding description, and defined in the claim appended hereto.

In said drawings:

Figure 1 is a view partly in side elevation and partly in vertical section illustrating my improved brush applied to aslat of a. Venetian blind.

Figure 2 is a view in longitudinal section of the brush.

Figure 3 is a view in transverse section taken on the line 3-3 of Figure 1.

Figure 4 is a view in perspective of the brush element detached.

Figure 5 is a view in transverse section taken on the line 5-5 of Figure 4 and drawn to a larger scale.

plane of the head I for attachment to a suction line 3 of a vacuum cleaner, or other suction source, not shown. A slot 4 of uniform width extends into the head I from the front end thereof to within a short distance of the rear I end of said head.

An improved brush element 5 is provided for the brush head I which is adapted to be held therein without separate fastening means.

The brush element 5 comprises a skeleton. re- -silient, wire frame formed of a single piece of -wire bent upon itself to provide a pair of opposite, substantially horse-shoe shaped sides 6 connected together atone end of the frame by a cross stretch 1, preferably bowed, one of the sides 6, at the other end of the said frame, having an angular terminal stretch 8, similar to the stretch I, but disconnected from the other side i of the 2 frame. The sides 6 of the described frame are spaced apart a distance slightly greater than the width of the slot 4.

Bristle binders 9 are provided on the sides 6 of the described frame having the form of inner and outer pairs of strips III, II of flexible material stitched together, as at I2 to provide a double thickness hem fitting tightly around the sides 6 and extending substantially along said sides to the stretches I, 8. The strips III, II are of any suitable material adapted to tightly grip the sides 6 against turning'around the same, for instance cloth, or rubberized fabric, and may be otherwise anchored to the sides as by cement, not shown. Bristles l3 are folded around the inner strips ID of the binders 9 and in the outer strips l I to form pairs ecured between the strips I0, H by the stitches l2 and extending equidistantl out from between said strips. The bristles l3 extend from each binder 9 toward the other binder and are preferably spaced apart slightly between said binders.

The described brush element 5 is fitted endwise in the head I parallel with the slot 4 between the top and bottom of said head with the binders extending along the longitudinal edges of the slot 4 behind said edges and with the stretches I, 8 of the sides 6 extending similarly along the ends of the slot 4 and fitting against said head at said rear ends, as best shown in Figures 2 and 3. In this position of the brush element, the same is held tightly in the head I by said top and bottom,

of the head, by the stretches I, 8 fitting against said head and by reaction of the sides 6 against the side edges of the slot 4 and pressure of the stretches I, 8 against the edges of the slot 4 at the ends of said slot. Obviously the sides 6 of the described frame may be flexed sufliciently for insertion of the brush element 5 endwise into the head I, and for removal from said head for replacement purposes.

In using the described brush, the same is manipulated with a reciprocatory motion with the bristles l3 straddling the slats l5 of a Venetian blind l4 as shown in Figure 1, the suction drawing the dust and dirt out of the head I in a manner which will be clear.

The-foregoing will, it is believed, .sufllce to impart a clear understanding of my invention, without further explanation.

Manifestly, modifications in the invention, as described, may be resorted to without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

What I claim is:

A suction cleaning brush head for straddling a slat to clean the same comprising a hollow substantially oval head provided with a slot in the median plane thereof extending part-way around the same, and a horseshoe shaped brush element comprising a single piece, resilient wire frame embodying a pair of substantially parallel horseshoe shaped opposite sides connected together at the open end of said frame and spaced apart a distance slightly greater than the distance between opposite edges of said slot, said sides fitting against said edges on the inside of the head and lying in planes parallel to the plane of said slot and extending along said edges to clampingly engage the same and be removably held in said head, and brush bristles fastened to said sides to extend from each side toward the opposite crosswise side 0! said slot.
