UNITED- sums Piurlazlxu OFFICE VENETIAN BLIND DUSTING BRUSH Harold Simon Bush, San Antonio, Tex.
Application May 10, 1948, Serial No. 26,021
Y 1 Claim. n Y 1 This invention relates to a brush adapted for dusting or cleaning Venetian blind slats.
An object of this invention is to provide a brush embodying a pair of brush elements which are Vengageable on opposite sides of a Venetian blind slat and movable lengthwise of the slat so as to clean both sides of the slat in one operaion.
Another object of this invention is to provide a pair of brush members with a handle projecting from each member, one of the handles being relatively rigid with the other handle yieldable, so that the desired pressure may be applied to the brush members. l
A further object of this invention is to provide a brush of this kind wherein the brush heads may be removed for cleaning or replacement.
With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.
In the drawing,
Figure 1 is a plan View of a brush constructed according to an embodiment of this invention,
Figure 2 is a sectional view taken on the line 2-2 of Figure 1,
Figure 3 is a fragmentary sectional View taken on the line 3 3 of Figure 1,
Figure 4 is a sectional view taken on the line 4 4 of Figure 2.
Referring to the drawing, the numerals I and II designate generally a pair of brush members which are disposed with their heads in confronting relation so that they may be engaged on opposite sides of a Venetian blind slat. The brush member I I includes a holder I2 of channelshape, which has extending from the center thereof an elongated handle I3 which is relatively rigid. In the present instance the handle I3 is secured to the holder I2 by fastening means I4 but it will be understood that where the holder I2 and the handle I3 are formed of plastic or similiar material the handle and holder may be formed as an integral unit.
The holder I2 has removably mounted therein a brush head generally designated as I5. The brush head I5 includes a relatively rigid back member I6 which engages in the holder I2 and in the present instance the head I5 is formed of sheeps wool I1 and the skin I8, the latter being xed in any suitable manner to the back I6. It will be understood that the brush head I5 while herein disclosed as being formed of sheeps wool, may be constructed of any suitable material,
syntheticor natural, the use of sheeps wool rbeing only one example of a brush head for use with the holder I2.
The brush member I0 includes a channelshaped holder I9 which has mounted therein a brush head generally designated as 20. The head 20 includes a relatively rigid back member 2| engageable in the holder I9, and a brush element formed of sheeps wool 22 and including the skin 23 is secured to the back 2l and is disposed with the fibers in confronting position to the bers Il. The holder I9 has secured thereto an elongated resilient handle generally designatedas 24, which is formed of a resilient wire twisted upon itself between the ends thereof, as indicated at 25. The handle 24 includes a pair of divergent members 26 formed with eyes 21 which are secured to the holder I9 by fastening means 28. While the fastening means 28 is herein disclosed as being short screws or the like, it will be understood that these fastening means vmay be rivets, grommets or other suitable fastening means, and where the holder I9 is formed of metal, the divergent ends 26 of the handle 24 may be welded or otherwise rmly secured to the holder I9.
The handle 24 includes at its rear end an elongated loop 29 adapted to overlie the flat upper surface 3l! of the handle I3 and a bolt 3l carried by the rear portion of the handle I3 extends through the loop 29. A wing nut 32 is threaded onto the bolt 3| and is adapted to clamp the loop 29 onto the handle I3. As disclosed in Figure 2, the handle y24 is longitudinally bowed so that the confronting faces of the brush members I9 and I I will be disposed in parallelism and so that when the two handles are grasped in one hand, the resilient handle 24 may be pressed toward the rigid handle I3 so as to thereby place the two brush members under the desired pressure for wiping or cleaning the opposite sides of the Venetian blind slat.
In the use of this brush structure, the slat is interposed between the two brush members I0 and II and the brush members are then moved lengthwise along the slat. The two handles I3 and 24 are grasped in one hand and pressure is applied to the two brush members by squeezing the handles toward each other, the resilient handle 24 bending inwardly toward the rigid handle I3. The brush heads may be partially cleaned by loosening the wing nut 32 and swinging the brush heads away from each other and then shaking or otherwise loosening the dust or dirt particles from the brush heads.
In the event it is desired to more thoroughly clean the brush heads, these heads may be removed from the holders by endwise movement which will disengage the backs I6 and 2| from the holders l2 and I9 respectively. The brush heads can be renewed where the fibers or bristle structure is worn or unduly compacted, it being only necessary to slide the new brush heads into the holders I2 and I9.
I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.
What I claim is:
A Venetian blind dusting brush comprising a pair of confronting brush heads, a 'channel shaped holder for each head, a relatively rigid handle xed at one end to one of said holders, a resilient longitudinally bowed twisted wire handle including divergent integral members on one end thereof fixed to the other of said holders on its outer face, a loop formed on the other end of said resilient handle, and releasable fastening means comprised of a bolt extending through said loop and into said rigid handle and a wing nut; for securing said handles to- 5 gether.
HAROLD SIMON BUSH.
