omi,limita-TOOL.

To aZZ whom-t may concern: I

Be it known that I, JOSEPH D. DRUM, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State oi' Pennsylvania, have invented new and yuseful Improvements in Cleaning-Tools, of which the following is "a specification.

The present invention relates to vacuum cleaners,u and more particularly to tools for use with vacuum cleaners.4

It has for its object toprovidea cleaning tool, designed in the present embodiment to be secured to thehead of the ordinary suction tool, and its specific purposeis to `provide for a complete cleaning or sweeping of the surface under treatment without materially interfering with or limiting the intake capacity of the cleaner, the present. embodimentl being intended more particularly for use on hard or polished surfaces, such as hardwood floors, although obviously not limited to such use. v

In order that the invention may be understood by those skilled in the art` I have illustrated in the accompanying drawings one embodiment thereof, and that the best now known to me, although since this disclosure is purely illustrative and not rei strict-ive, I do not limit myself to the specific mechanical expediente-for carrying my .source be the stand pipe of a stationary system or a portable vacuum cleaner machine.

The tool proper, indicated at 6, is 'secured to the suction head 4.- in any suitable manner so as to secure a tight joint, the particular expedient here adopted being ledges 7 with clamping screws 8 arranged to secure the tool 6 in place.

The under or active surface of the tool 6 is provided centrally with `a long relatively narrow opening or suction mouth 12* on Specification of Letters Patent.- Patented All". 27, 1912i. Appl'icatin led April 14, I9ll. Serial N0. 621,111. i

epposite sides of which are a number of a utments 10 spaced .from one another to form wide intake passages 9 extending from the edge ofthe tool toward t-he mouth l2. The abutments 10 are preferably lozenge or diamond shape so arranged that their long axes are parallelto one another and trans- Verse to the length of the tool. Between the inner ends .of the abutmcnts 10,-adjaeent the mouth 12, are Atriangular or halt diamond shaped abutments 11 so placed that an angle of each of said abutments points outwardly, and the inclined sides thereof lie parallel to the adj'acentinclined edgesy of the abutments l0, and spaced therefrom to form two diverging channels 9 leading from each intake pasage 9, and opening into the mouth 12. From this it will be evident that the converging intake passages 9 with i theehannelsQ are ydisposed angularly to the direction in which the tool is moved, and thus expose at some time in the course of its movement the entire fioor to one or more ofsaid intake passages and channels through which air flows to the suction mouth, thus drawing all dust and dirt into the tool and through the handle It is to be noted that as the points only of the lozenge shaped abutments l0 are presented directly in the line of movementl of the tool, the mouths or entrances of the intake passages 9 are wider than anyl other part, and that by placing between the inner ends of said abut-ments the semi-lozenge shaped abutments 11, the oblique channels 9 are formed which lead from said intake passages, through which channels air flows to the suctionv mouth obliquely acrossl the line of movement of the tool, thus insuring the collection of all dirt and dust over the surface traversed by said tool.l

By forming the abutments 10 and lLIas shown, the likelihood of their breaking .n

. vment of my invention I do not wish to be yas '10 lat the ends adjacent the suction mouth 12.

I have shown the channels 9a of the intake passages 9 as laid at an angle of sixty degrecs to the base line, butthis angle, as well as the line of thepassage, may, of course, be varied as desired so long as the brokenjoint disposition of abutments and intake' passages is so preservedas to 4preventv any unswept lines leading from the edge of the tool to the intake mouth.. Preferably these abutments 10 and 11*vr will be made of felt or fiber suitably secured to the tool proper which maybe of wood or any suitable material, although =the-materialas.well as the shape of the abutments, may be varied as described. y

While I have shown a particular embodilimited to the exact mechanical details disclosed, .as these may be varied within the l'limits of the-mechanician withoutl departing from my invention. f.

I claim 1, A sweeping tool for vacuum cleaners .having a long relatively narrow suction mouth, andswee ing abutments on the face of said tool..ad]acent said lmouth of such shape asto form intake .passa'es inwardly `converging walls, eal

' their bases bordering having passage v opening into narrow oblique channels leading int-o the suction mouth.

2. -A sweeping tool for vacuum cleaners having a long relatively narrow suction mouth, sweeping abutments so arranged as toform convergmg intake passages opening into obliqueI channels leading to said mouth at oppositely disposed angles to the line of movement of said tool.

3. A sweeping tool for vacuum cleaners having a suction mouth, flat lozenge shaped sweeping abutments arranged to form converging intake passages, iat vsemi-lozenge sweeping abutments between the inner endsA `of. the lozenge shaped abutments, and spaced therefrom to form diverging air channels leading from the intake passages to the suction mouth. A c 4. A sweepingtool for v acuum cleaners,

tially triangular sweeping abutments bordering said mouth, anda series of substantially lozenge-shaped sweeping abutments arranged in overlappedy relation to said tri- .having a suction mouth, a series of sulstan-v angular abutments to provide intake-pasp sa es. f

A sweeping tool for vacuum cleaners hav-ing a suction mouth, a series of ,substantiallyA triangular sweepin abutments with said mouth, and a lozenge-shaped seriesA of substantially vsweeping abutments arranged in overlapped relation to and extending outwardl Abeyond said triangular abutments to provi e mtakepassages.

In testimony'whereofl I' have hereunto set` my hand in presence of two subscribing "witl` nesses.
