" 2 claims. '[(cl. is-im This invention relates to a novel and improved lightweight readily shiitable and maneuverable dusting mop for domestic use, the same being of the so-called vacuum type and including suction means and dust collecting and disposal means.

More specically, I have evolved and produced a simple and economical dust-mop characterized by a limited suction principle rendering the structure apt and suitable for light work dust-mopping floors. IIt is not intended for heavy rugs and, therefor, the suction characteristics .can be quite limited, though it may be possible for use on scatter rugs, -it ls primarily a quickly maneuverable dust lpick-up mop for simple lightwork accomplishments.

In carrying out the principles of the invention I have adopted for use a simple and economical electric dust-mop, the same characterizedl by a triangular or three-cornered flattened nozzle head of sufficiently low vertical height as to be l small and flat enough to get under. radiators and low beds and furniture, the same being adapted to pick up lint,`dust, and perhaps a small amount of grit, something more than the ordinary nonsuction dust mop will do. The collected extraneous matter and'dirt is seized and picked up by the quick maneuverable caster supported nozzle head and carried up and deposited in a twistable- Other features and advantages will become' more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is a side elevational view of a dustmop of an electric motor suction-equipped type constructed in accordance with the principles of the instant invention.

Flgure 2 is an enlarged view partly in section and partly in elevation detailing the construction oi' the head and motor compartment .and adjacent, portions of thehandle structure.

Figure 3 is a bottom plan view of the triangular or triple cornered head. i

Figure 4 is a perspective view of a fragmentary character, showing the detachable mount and adapter for the hollow handle. Figure 5 is a sectional view through the lower valved portion` of the hollow handle.

Referring nowto the drawings by distinguishing reference numeralsl and particularly to Figure 3, it will be observed that the head, as a unit, is denoted by the numeral 6 and comprises a casting of general triangular form. At the three corners on the bottom thereof, which bottom is open, I provide self-adapting swivelling casters 1. Attached toand suspended from the marginal portions are suitable bristle `o1'- equivalent 4brushes -8 and 9, these being disposed in converging toward the apex end of the head. The suction nozzle at the median portion is denoted by the numeral l0 and includes a duct leading into an adapter shield Il for the fan I2. The latter is located at the right-hand end of the nozzle duct and projects into the continuing duct which forms the upstanding handle accommodation neck Il (see Figure 2). The fan is driven by a suitable motor I4 in an enlarged or accommodation portion I5 in' the head construction, the motor being supported on an appropriate anchor or bracket i6. The numeral I1 designates a foot-tripped electric switch for turning the motor "oiI and on."

Attached suitably to the neck l2 is an appropriate flexible coupling I8 which we canconveniently refer to. as an adapter coupling. This is permanently secured in any suitable way to the neck and at its opposite end it is provided with a collar It which, as shown in Figure 4 is provided with bayonet slotsl 20, said collar receiving the lower reduced end 2l of the tubular hollow handle 22 and said reduced'portion being provided with pins 2l coacting detachably with a bayonet slot.` The upper end of the handle is provided with an air vent having a covering screen 24 oi appropriate mesh for dust iiltering and air e purposes. Also, on the upper-end is a suitable hand-grip 25.

A disk-like damper-type valve 26 is mounted in the lower portion of the handle just above the coupling means and this valve is pulled to normally open position by a contraction spring 21,

. therebeing provided a stop Din 28 to limit the swing of the valve to the half-open position seen inFigure 2. The axle means on the valve is pro- 2 -v ascuas vided v.with a crank 2l with which an operating rod 30 is connected. 'I 'his is a push-pull operating member and provided with an appropriate iinger hook-up operating element II- as shown in Figure 2. It is thus possible for the. user' to open and close the valve, as desired, against the tension ofthe spring.

Suitable accommodation hooks u and Il are mounted on the handle to accommodate the cord 35 as is customarily done on regular or conventional type vacuum cleaners.

Ordinary mops are such that it becomes necessary for the user to shake the same every so often out of drafty windows and the like and this is attended by' objectionable results of many and varied kinds. However, it is not the purpose of the instant description to dwell upon commercial aspects or the objections and advantages of the old. mop as compared to the electric dust-mop herein shown and described.

' It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding oi' the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming within the ileld of invention claimed may be resorted to in actual practice, if desired.

Having described the invention, what is claimed as new is:

l. As a component part of a structure of the class described, a hollow dust collecting and disposal handle having a hand-grip at its upper end and flexible attaching means at its lower end, a valve disk mounted and confined for oscillation in said handle, a crank connected to and for operating said valve disk, said crank being located on the exterior of said handle, a push-.pull rod for operating said crank, said rod .being slidably mounted on said handle, said handle being provided adjacent said hand-grip with.a vent, and said vent being covered by a-iilter-screen.

2. A handle assemblyrcr use in association with a vacuum-type dusting mop of the class described comprising an .elongated tubular and rigid handle, a handgrip secured to the upper end thereof and closing said upper end, the area of the handle valve mounted in said handle, and an operating rod slidably mounted on the exterior of the handle connected at its lower end with said valve for closing same against the tension of the spring,

the upper actuating end of the rod being located within convenient reach 4of the hand grip.
