Patented Nov. 28, 1922.

Patented. Nov. 28, 1922.




Application filed July 21,

To all whom it may concern:

Be it known that I, THEODORE G. JOHN- SON a citizen of the United States, residing at kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Dusters, of which the following is a specification.

My invention relates to improvements in dusters, and one object is to provide a device ofthis character which can be used to advantage in dusting off highly polished furniture, automobiles, etc.

A further object is to provide a duster embodying members adapted to straddle chair backs and rungs, wheel spokes and other round objects difficult to dust with the ordinary duster.

Other objects will hereinafter appear, and in order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a perspective view of the duster with the upper half of the pocket removed.

Fig. 2 is an end elevation of the pocket.

Fig. 3 is a side elevation with the pocket removed.

In carrying out the invention, I employ a handle 2, preferably, made of wood and of any suitable length.

4 designates a wire, the intermediate portion 6 of which extends through a transverse hole 8 in the forward ortion of the handle 2. After being passed through the hole 8, the wire 4 is bent forwardl the two strands being twisted together ad acent to the forward end of the handle 2 as indicated at 10. The two strands are then curved in oposite directions and extended forwardly to orm a pair of tines 12, which diverge at their forward portions 14 and terminate in eyes or loops 16. The twisted portion 10 of the two strands is bent downwardly to form an offset 18, so that the tines 12 will be on a lower plane than the handle 2.

20 designates a pocket made of canvas or other suitable material. Said pocket has a mouth or opening 22 at one end which communicates with a pair of forwardly extending legs 24 spaced a suitable distance apart as disclosed by Fig. 1. The pocket 20 is covered with soft material 26 consisting,

refer-ably, of cotton cords each of which 1s secured intermediate its ends to the pocket 20 by stitching 28. The soft material 26, preferably, covers the entire outer portion of the pocket 20 to remove dust and protect 1921. Serial No. 486,840.

highly polished surfaces over which it is passed from becoming scratched. A string, cord, or tape 30 is secured intermediate its ends to the top of the mouth 22 and is adapted to be tied around the grooved portion 22 of the handle 2 to reliably hold the pocket 20 in position upon the tines 12.

In dusting a broad surface like a table top for instance, the offset 18 permits the bottom of the pocket to lie flat upon such surface, while the handle 2 is raised sufficiently to prevent the fingers of the hand grasping said handle from coming into contact with such surface. In dusting the rungs of chairs, spokes of wheels, and other round objects, the'tines 12 are caused to straddle said objects, so that the soft material 26 at the inside of the legs 24 will thoroughly remove any dust present. The diverging forward portions 14 of the tines 12 make it easy to force said tines over a round object wider than the space between the legs 24, the tines themselves being resilient so that they can spread apart as they are forced over a relatively wide object. The loops 16 at the ends of the tines overcome any danger of said ends being forced through the forward ends of the legs 24.

When the pocket 20 becomes soiled it can be removed from the tines l2 and washed, and when worn out can be replaced by another without discarding the entire duster.

From the foregoin description it will be readily understood that I have provided a duster embodying the advantages above pointed out, and while I have shown and described the preferred construction, combination and arrangement of parts, I reserve the right to make such changes as properly fall within the spirit and scope of the appended claim.

Having thus described my invention what I claim and desire to secure by Letters Patent, is:

A duster consisting of a handle, a wire secured intermediate its ends to said handle and formed into a pair of forwardly projecting tines diverging at their forward portions and terminating in loops, and a pocket having legs into which said tines extend.

In testimony whereof I afiix my signature, in the presence oftwo witnesses.
