ROBERT A. MAYO, OF PHILADELPHIA, PENNSYLVANIA.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 580,190, dated April 6, 1897.

Application filed October 24, 1896. Serial No. 609,882. (No model.)

T 0 (bZZ whom it may concern.-

Be it known that I, ROBERT A. MAYO, acitizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Carpet- Sweepers, of which the following is a specification.

My invention has relation to an appliance for sweeping carpets or the like, and in such connection it relates to the particular construction and arrangement thereof.

The principal object of my invention is to provide a simple, durable, and effective carpet-sweeper-that is, one so arranged as that by exerting pressure through a hand operating rod the brush through its actuatingwheels is brought into frictional contact with the floor-wheels to impart motion to the brush, so as to be permitted to contact with the surface of the carpet to lift by a rotary action lint or other extraneous matter into receivers provided in the sweeper and by a reverse movement of the hand operatingrod the brush-wheel to be released from contact with said floor-wheels, thereby preventing rotation of the brush and matter carried in the sweeper from being again deposited upon the carpet, and at the same time so arranged as that the energy exerted to manipulate the sweeper is lessened, as well as noise incident to operating the same.

My invention, stated in general terms, consists of a carpet-sweeper constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and characteristic features or scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings, forming part hereof, in which Figure 1 is a side elevational view of a carpet-sweeper embodying main features of my invention, and Fig. 2 is a top or plan View thereof.

Referring to the drawings, A represents the housing of the sweeper, of any suitable form, provided with two rubber-edge-covered floorwheels a and a on each side thereof mounted upon shafts a and a extending through the body of the sweeper. Beneath the shaftsa and a extending through the sweeper, are

provided dust-receptacles B and B, as clearly illustrated in Fig. lot the drawings.

0 is the hand operating-rod of the sweeper, engaging at the lower end a socket c of a U-shaped metal frame 0, the arms 0 and c of which frame pivotally engage at c on the respective sides the arms d of the cams D. These cams D are provided with double concave-shaped slots d, as clearly illustrated in Fig. 1. Each cam-lever armd is pivotally supported at d to a plate d secured to the side wall a on each side of the sweeper. The side walla is cut away, forming a circular opening a which merges into an oblong opening a on each side of the sweeper.

E is the rotary brush, journaled in oblong slots g of frames G and G, secured .to the sides of the sweeper. On the respective free ends of the brush-journals are mounted rollers 6, adapted to travel in the concave-shaped double slots of the cams D in order that by means of the hand operating-rod O the brush E may be rendered, respectively, operative and inoperative therein by. either pushing or pulling the said rod 0.

On the extreme outer end of each journal of the brush is mounted a wheel F, which is adapted to be brought into frictional engagement by means of the hand operating-rod O, cams D, and rollers c, with the rubber-edgecovered floor-wheels a and a to receive motion therefrom in the pushing and pulling actions of the sweeper overa floor, and thereby to impart rotary motion to the brush E to lift lint and other extraneous matter onto the same and into the dust-receptacles B and B.

In Fig. 1 the sweeper is illustrated in an operative position with the wheels of the brush in frictional contact with the rubbercovered floor-wheels Ct and a to receive motion therefrom, and with the cams D in positions, which by a pushing movement of the rod G the sweeper may be impelled to actuate the brush E, and thereby to cause extraneous matter to be lifted through its rotary action into the respective receptacles B and By then drawing or pulling on the hand operating-rod C, the wheels F, connected with the journals of the brush E, can be released from the floor-wheels a and a and the rotation of the brush momentarily prevented thereby, so that matter lifted by the brush and deposited in the receptacles B and B, of the sweeper remains therein until removed therefrom in any preferred manner, and by then a still further pulling movement of the rod 0 the brush E may again be brought into operative condition, or even by then pushing upon the hand operating-rod O the parts hereinbefore explained may again be caused to assume the position, as illustrated in Fig. 1, to efiectively remove from the carpet by the rotation of the brush E extraneous matter into the receptacles B and B of the sweeper.

' It will be manifestly obvious to those skilled in the art to which my invention appertains that as to minor details modifications may be made without departing from the spirit or scope of my invention, and hence I do not wish to bev understood as limiting myself to the precise construction and arrangement of all the parts as illustrated and hereinbefore explained; but,

Having thus. described thenatu re and obiec sj my n e'nt o hat I claim s w, and desire to secure by LettersPatent, is-

1. The combination with a carpet-sweeper case provided with fioor-wheelsof a hand operating-rod connected with pivoted slotted cams located on each side of said case, a brush in said case, rollers mounted on the journals 3o nipulation of said hand operating-rod, substantially as and for the purposes described.

2. The combination with a carpet-sweeper case provided with floor-wheels, of a. hand operating-rod, cams provided with double concave slots and having arms pivotally sup- 4o 1 ported from the sides of said caseya. brush ournaled in vertical oblong slots of said case, rollers mounted on the journals of said brush and engaging the. slots of said cams and wheels mounted on said brush-journals and adapted to bebrought into engagement with said floor-wheels by manipulation of said handoperating-rod, substantially as and for thepurposes describedj In testimony whereof I have. hereunto, set my signature in the presence of two subscribing witnesses. r
