Filed:

Mar 13, 1981

Appl. No.:

6/243413

Inventors:

Don W. Vermillion - Anderson SC
Francis S. Gromek - Anderson SC
Scott S. Bair - Atlanta GA

Assignee:

The Singer Company - Stamford CT

International Classification:

A47L 534

US Classification:

15339

Abstract:

A suction cleaner having a chassis including a suction nozzle inlet at the bottom thereof and first and second sets of wheels supporting such chassis for movement on a floor surface is provided with a nozzle height adjusting mechanism comprising first axle means carried by said chassis for rotatably supporting said first set of wheels, second axle means including a central portion having a pintle shaft mounted therewith and with the chassis for enabling rocking movement of said axle means relative said chassis, an actuating portion on one side of said pintle shaft, and a pair of offset arms formed on an opposite side of said pintle shaft extending laterally outwardly thereof for journaling said second set of wheels, said offset arms being longitudinally spaced from said first axle means, an adjustment lever journaled on said chassis having one end portion angulated to engage said actuating portion so that rocking movement of said adjustment lever rocks said second axle means about said pintle shaft and thereby raises or lowers said second set of wheels relative said chassis and a second end portion extending through said chassis and being manually engageable by an operator to adjust the nozzle height as it is rocked back and forth thereby.

International Classification:

US Classification:

Abstract:

A brush or agitator roll of a suction cleaner for carpets or other floor coverings is provided with a plurality, for example, a pair of diametrically opposed longitudinally extending spiral grooves and a bristle/agitator strip is spirally, slidably engaged in each spiral groove. Each strip has a section including a band forming part of a crowned pulley for a drive belt. On either side thereof a series of holes is provided for receiving bristle tufts. On each side, the strip is provided with a radial hole at a medial location with each succeeding bristle hole being elongated so that its inner wall is radial and the outer wall is inclined away from the center by an amount equal to the inclination of the adjacent hole plus a fixed incremental amount. Thus, although the inner edge of each hole is generally upright or radial, the outside edges are successively angled outwardly so that the holes can be molded utilizing a single core strip and the bristle tufts can be inserted and stapled radially and yet will have substantial bristles angled outwardly so as to provide a brush having a line of bristles effectively longer than the supporting strip. Grooves are also provided on the back and two sides of the strip to increase its flexibility, enabling it to be slid into the groove on the roll without the necessitating pre-heating of the strip to soften it.

Appl. No.:

7/049369

Inventors:

Don W. Vermillion - Anderson SC

Assignee:

The Singer Company - Stamford CT

International Classification:

F16L 3724

US Classification:

285 7

Abstract:

A connection assembly is particularly useful for positively connecting a flexible hose member with an inlet plug for a suction source while being adapted for subsequent disconnection without requiring any specialized tools. In connecting operation, an integral extension portion of a flexible hose member is telescopically inserted into an inlet plug to a predetermined longitudinal stopping point therein, and then rotated so as to cause engagement of projections formed on the extension portion and projection-receiving holes formed in the inlet plug. Such engagement rotatably and longitudinally secures the flexible hose relative the inlet plug. Slots are formed in the inlet plug for guiding the hose member projections during longitidinal movement of the hose member. The hose member may be selectively withdrawn by reverse rotation of the hose extension portion and longitudinal removal thereof from the inlet plug. During such reverse rotational movement, a camming surface is used to assist withdrawal of projections from their respective holes for disengaging same without requiring special tools.

Assignee:

The Singer Company - Stamford CT

International Classification:

A47L 904

US Classification:

15390

Abstract:

An override clutch device is disclosed for use in a vacuum cleaner having a powered rotary brush. The override clutch device is arranged such that should the torque require to rotate the brush exceeds a predetermined level, the drive mechanism is disengaged from the brush thereby allowing the drive belt to continue to operate without damage. An audible signal is emitted to alert the operator of the malfunction.
