FRANK J'. MATCHTTE, 0F MILWAUKEE, WISCONSIN.

VACUUM-SWEEPER.

Specification of Letters Patent.

Patent-ed Mar. 1'2, 1912.

Application filed June 12, 1909. Serial No. 501,707.

T o all whom 'Zt may concern.' I

Be it known that I, FRANK J. MATCHETTE, a citizen of the'United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Vacuum- Sweepers, of which the following is a specification, reference being had to the accompay drawing, forming a part therof.

This invention lrelates more particularly `to tools for taking up and `removing dust and .dirt with an air draft from carpets, rugs and the like. Its main object is to simplify and improve the construction and operation of tools of this class, and it consists in the construction, arrangement and combination of parts as hereinafter particularly described and defined in the claims.

In `theaccompanying drawing like characters designate the same parts in the several figures.`

Figure 1 yis a plan view of a sweeper embodying the invention; Fig. 2 is a longitudinal section of the same on the line 2 2, Fig. 1; Fig. 3 is a transverse section cutting the tubular shank lengthwise on the line 3 3,

Figs. 1 and 2; and Fig. 4 .is an end view of the tubular sweeper head.

The sweeper comprises an open frame or shoe a, a tube b, and a tubular shank c' in which the tubular handle or arm d for operating the sweeper andconuecting it with 'a pump or other vacuum producing means, is removably fitted.

The frame or shoe a may be cast as shown, in one piece, with parallel side bearing pieces e connectedat the ends by arches f and located at a distance from the tube b. T he arches are formed in their inner and opposing sides with curved grooves g lconcentric with the alined openings in lthe arches. The tube b, which is preferably made Vof sheet metal or seamless tubing, is

pf cylindrical form and has a longitudinal slot in the under side extending farom end to end, the edges of the metal next to the slot being fianged or bent `inwardly and forming with the sides of thetube, cleaning lips h around orunderneath which the air has tol pass to enter the tube. v

i is a segmental sleeve in which the tube b is fitted, and which in turn is fitted at the ends into the arches f, in which it is secured with the tube by. pins j or other suitable means. The shank c terminates at one end 7 in a laterally extended concave bearing la,

which is fitted to turn upon the sleeve i and is held and guided at the ends in the grooves g so as to maintain a close working fit between said bearing and said sleeve. The opposite end of the shank is counterbored and 'provided as shown in Fig. 3, with an A elastic split coupling ring Z, the normal internal diameter of which is slightly smaller than the external diameter of the tubular handle or arm al. The coupling ring Z is loosely confined in the counterbore of the shank by a ring m, which is forced into or otherwise secured in place in 'the shank. Disks n and 0 are fitted and secured in the ends of the tube b, the disk o being formed with an opening p which affords access to' the interior of the tube and means for removing obstructions therefrom. This opening is normally closed by a pivoted cover g. The disks are cut away or recessed as shown in Figs. 2 and 3, next to' the slot in the under side of the tube, thus aHording 'restricted openings at thos points for the ad` mission of` air into the ube. The effect of these openings is to admit a small excess of air at points remote from the tubular shank aand thus make uniform the air draft or current throughout the length of the sweeper.

The tube b and the sleeve z' are formed in the upper part thereof with an opening or port r lthrough which the interior of thev tube is in constant communication with the passage inthe tubular shank c, whatever the angular position of the arm or handle d may be. i

The lips h along the sides of the slot in the under side of the tube, projectslightly below the adjacent edges of the sleeve z' and the bearing pieces e of the shoe. so as to sink into a carpet, rug or other fabric, in the operation of 'the sweeper thereon, and thus cause the air as it rushes around or underneath said lips into the tube through the slot in the underside thereof, to more effectively dislodge and remove dust .and dirt `from the carpet, rug or other fabric.

In the operation of the tool, the handle or arm d swings freely with the. shank c around the tube b in a plane at right angles to its axis, assuming any position orangle relativel lto the plane of the bearings e of the shoe most suitable and convenient for the operation ofthe tool 'under varying conditions. The bearings e of the shoe lbeing located at some distanceI from and on opposite sides of the tube b, carry the tube withl the slot on the `under side thereof in the proper relation to the work, whatever position or angle the handle or operating arm may assume.

For sweepin under low furniture, fixtures or other o jects, `the handle or operatsides of and approximately 'parallel with said tube `and. connected at v the ends by arches in which the tube is fitted and secured, and a tubular shankhaving a transverseconcave bearing fitted to turn upon said tube and guided at the ends in said arches, with the passage in the shank in communication with the port in said tube.

2. In'a vacuum sweeper the combination of'a tube having closed ends, a longitudinal slot in the under side and a port in the upper middle 'portioma shoe having bearings on opposite sides of said tube and approximately in the plane' of said slot and connected at the ends by arches in which said tube is secured and` which are formed in their innerk sides with `grooves concentric with'the tube, and a tubular shank terminating at one end with a concave bearing which is fitted upon said tube over the port therein and has! tongues at the ends fitting into and 'guided in 'the grooves in said arches.

3. n a vacuum sweeperv the combination of a shoe having bearing pieces connected by arches a metal tube having a longitudinal slot in the under side, the edges of the metal next to the slot being flanged in- Wardly,a segmental reinforcing sleeve iittedl over the middle portion of the tubel and se cured therewith in the arches ofthe shoe. and a tubular shank terminating at one end in a concave `bearing which is fitted to turn on said sleeve. and is guided 4 concentric therewith in said arches,` the tube andi sleeve being 'formed with a port through which the passage in the shank communicates with the 'interior of the tube.

4. In a vacuum-sweeper the combination of-a shoe having bearing pieces connected by arche s,v a segmental sleeve fitted land" secured 1n said arches, a metal tube tted and secured in said VsleeveV and having a longitudinal slot in the under side, the edges of the metal next to the slot being anged in-l wardly and forming with the adjacent sides of the tube cleaning lips which .project zbelow the adjacent edges of the sleeve,.and a tubular yshank terminating atene end in a transverse concave bearing which is fitted to turn on said sleeve and is guided concentric therewith in said arches.

5. ln a vacuum sweeper the combination of an open frame or shoe having side bearing pieces connectedat thejends by arches which are formed with grooves in their inner and opposing sides, a segmental sleevefitted in said arches, a cylindrical tube fitted in and secured with said sleeve in the arches and between the bearing pieces of said shoe and having closed ends and a longitudinal slot with inturnededges along the underside, and a tubular shank terminating at one end in a laterally extended concave bearing fitted to turn on said sleeve and guided at the ends inthe grooves ofsaid arches, the tube and sleeve' being formed with a port inposition to communicate ywith the passage in said shank. A

6. \In a vacuum sweeper the combination of a ttube having a longitudinal slot in the under side, a shoe `fixed to said tube and having bearingsfon ,opposite sides thereofand at a distance therefrom, t-he tubealong the sides of said slot extending below said bearings, and a tubular shank having a hinge or pivot -connection with the tubeand communicating with the interior of thgough a port therein.

n a vacuum sweeper vthe combinationv of a tube having a longitudinal slot in the under side and restricted openings ,in the ends next to the slot, a shoe fixed to said the tubel tube and having bearings on opposite sides thereof and at a ydistance therefrom, the

tube along the sides of the slot extendingbelow said bearings, andy a tubular shank havinga hinge' or pivot connection withy the tube and communicating with the interior of the tube-.through a port therein.

. In witness whereof I heretofatlix my signature in presenceof two witnesses.
