2 Claims.

This invention relates to mops and dusters, and more particularly to a dry mop having a pair of duster sections detachably connected therewith.

One object of this invention is to provide a dry mop of the above nature in which the detachable duster sections may be used as hand clusters if desired.

Another object is to provide a dry mop of the above nature including an H-shaped holder frame, to which the ends of a pair of duster units are swingably attached, whereby the dust may be easily removed therefrom by shaking.

A further object is to provide a dry mop and frame of the above nature which will be relatively simple in construction, inexpensive to manufacture, easy to assemble and manipulate, compact, easy to clean, ornamental in appearance, and very efficient and durable in use.

With these and other objects in view, there has been illustrated on the accompanying drawing one form in which the invention may be conveniently embodied in practice.

In the drawing:

Fig. 1 is a plan view of the improved dry mop and frame, shown partly broken away and partly in section.

Fig. 2 is a development View of one of the cluster units. I

Fig. 3 is an enlarged sectional view taken on the line 33 of Fig. 1.

Fig. l is an end View of the H-shaped frame.

Referring now to the drawing in which like reference. numerals denote corresponding parts throughout the several views, the numeral It] indicates a supporting frame of substantially H-shape having parallel U-shaped side leg members II and I2 joined together by a cylindrical cross-bar I3each of said leg members II and I2 having a pair of parallel arms l4 and I5 extending outwardly at right-angles thereto. The cross-bar I3 has flattened ends l6 and Il securely fitted into a pair of elongated holes I8 formed in the leg members II and I2, respectively, to prevent relative rotation of said members and said bar (see Fig. 3). The central portion [9 of the cylindrical bar I3 between the leg members I I and I2 is adapted to be clamped between a pair of jaws 2B, 20 of an adjustable mop holder 22, which may be of any standard type, said clamping being accomplished by means of a thumb nut 23. An elongated Wooden handle 24 is secured to the holder 22, as by nails or rivets 25. The arms I4 and I5 of the leg members II and I2 are rounded at their extremities 26 and are provided with inwardly extending offset hooks 21, struck out from the material thereof at the corners where said arms join. the respective legmembers II and I2.

A pair of cluster units 28 are provided, each of which is composed of a plurality of short threads 29 of twisted yarn, laid transversely side by side and stitched to an elongated fabric tape 36, which has fabric pocket members 3| and 32 at its ends. The tape 30 is preferably twisted during manufacture, as shown in Fig. 2, and is adapted to be held automatically in such twisted condition by the interlocking of the threads thereof.

Each of the pocket members 3| and 32 is formed by folding a small rectangular fabric strip 33 upon itself with its open side edges stitched together to form a seam 34 (see Figs. 2 and 3), and said pocket members are secured to said tape 30 by a pair of converging lines of stitching 35, which lines form the bottoms of said pockets.

In order to provide for the detachable connection of said pockets 3|, 32 to the leg members II, I2, provision is made of opposed eyelets or button holes 36 in the adjacent sides of the open ends of said pockets, through which the hooks 21 are adapted to be inserted.

Operation In operation, when it is desired to assemble the dry mop, each of the duster units 28 will be detachably, connected to one of the leg members II and I2 by inserting the rounded arms I4 and I5 thereof into the pockets 3| and 32 as far as they will go-until the hooks '21 engage within the eyelets or button holes 36, as shown in Fig. 1. When both units 28 have been so assembled, the device is ready for use.

When it is desired to remove either of the units 28, the pockets 3| and 32 may be slipped off from the hooks 21-. It will be understood that when in their detached condition, either of the duster units 28 may be efficiently used as a hand mop or hand duster. The detached units may also be conveniently washed and passed through a clothes wringerthere being no metallic parts in its structure which might be caught in the wringer rolls.

One advantage of the present invention is the ease of removal of the dust by shaking, due to the flexible loose swinging connection of the duster units 28 to the hooks 21.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited. to the specific disclosure, but may be modified and embodied in various other forms Without departing from its spirit. In short, the invention includes all of the modifications and embodiments coming within the scope of the following claims.

Having thus fully described the invention, what is claimed as new and for which it is desired to secure Letters Patent, is:

1. In a dry mop, a substantially H-shaped frame having oppositely extending side leg members of U-shaped configuration, a pair of detachable duster units connected to the arms of said leg members respectively and having loose unsupported limp central sections, hooks being formed at the corners of said leg members, said duster units having eyelet holes to fit over said hooks.

2. In a dry mop, a cluster unit comprising a central twisted fabric yarn-holding tape, said tape having a pair of outwardly opening apertured pockets secured to the ends thereof, a U- shaped frame member having parallel outstanding arms extending from each end thereof and adapted to enter said pockets, and hook members formed on the inner ends of said arms for detachable engagement with said apertures to loosely secure the duster unit to said frame member in such a manner that the dust may be removed from said duster unit by shaking.

FREDERICK PREISSER.
