JAMES H. TOWNSEND, 0F GLOVERSVILLE, NEW YORK.

CARPET-SWEEPER.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed February 12, 1910. Serial No. 543,429.

To all whom it may concern:

Be it known that I, JAMES H. TOWNSEND, a citizen of thefUnited States, residing at Grlo'versville, county of Fulton, and State of New York, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings "is a top plan view of my improved carpet-sweeper with the handle and parts mounted thereon broken away for convenience of illustration. Fig. 2 is a View in side elevation of the same. Fig. 3 is a view in front elevation of the same. Fig. 4 is a vertical longitudinal section of the same taken on the broken line 44 in Fig. 1, with the long handle removed, its relative position in use being indicated by dotted lines.

Certain of the objects of the invention are to facilitate sweeping in close proximity to the base-board or furniture in a room 3. to provide a readily portable, hand-operated device having a receptacle for sweepings which can be used either with a hand-open ated rotatory brush forming a part of the device, or with a separate brush or broom; and to provide a portable sweeping device having a rotatory brush with means for supporting and operating the same by hand, either at a point near the floor by a person stooping, or at a higher point convenient to a person in a more erect position.

Other objects Will appear in connection with the following description.

In carrying out the invention, I provide a dust-pan or receptacle for sweepings with a handle attached directly thereto, and also with a longer handle removably attached thereto; a brush rotatively mounted and movable into and out of a position to cooperate with said dust-pan; means mounted upon said dust-pan for rotating said brush by hand; and hand-operated means mounted on said removable handle through which the brush-rotating mechanism mounted on the dust-pan can be operated.

Referring to the drawings wherein the invention is shown in preferred form, 1, represents a sweepings-receptacle or dust-pan having fixed at the back thereof a handle, 2, which may be of any known form, and whereby the pan may be lifted and held in any desired position.

The dust-pan is covered by a hood or lid, 3, pivotally mounted upon the cross-shaft, 4,

carried by the dust-pan, the side-walls, 5, of

the hood forming bearing-supports for the opposite ends of a rotatory brush-shaft 6. A cylindrical brush, 15, is fixed upon the brush-shaft, 6, to rotate therewith.

The hood and the brush carried thereby can be swung vertically so as to occupy either the position shown by solid lines or that indicated by dotted lines in Fig. 4.

The hood is adapted to be supported in raised position as indicated by dotted lines in Fig. 4, by the engagement of a pin, 7, carried by the hood with a spring-plate, 8, having an aperture adapted to receive said pin. The spring-plate, 8, can be pushed by hand out of engagement with the pin, 7, permit ting the rotatory brush to be swung down into position to cooperate with the dust-pan.

Fixed upon one end of the brush-supporting shaft, 6, is a sprocket, 9, connected by chain, 10, with a sprocket, l1, fixed upon the shaft, 4, which shaft is rotatively mounted upon the dust-pan and has fixed upon its opposite ends a pair of wheels, 12 and 13, which may be used as supporting wheels for the pan, and when so used serve as the means for automatically rotating the brush.

The device thus far described can be used in the manner of an ordinary carpet-sweeper by a person stooping to grasp the handle, 2, whereby the device can be pushed along the floor; or the handle can be grasped in a similar manner and the dust-pan supported with its front edge resting upon the floor, and the wheels, 12 and 13, slightly raised from the floor, as shown in Fig. 4, in which position the rotation of the brush can be accomplished by turning the wheel, 12, by means of the crank-handle, 14, thereon.

Said device can also be used as an ordinary dust-pan by swinging the hood and brush upward to the position indicated by dotted lines in Fig. 4, in which case the sweepings can be brushed into the dust-pan by an ordinary broom or brush-broom.

To adapt the device to be operated by a person in a substantially erect position, I have provided a removable handle attachment, 16, terminating at its lower end in a yoke, 17 having near, the :ends ofitsside-t arms, 18, apertures adapted to receive the the wheels, 12 and 13. Tharms, 18, of the handle yoke, project somewhat beyond the tanee from "the axis of-the shaft,*4, thant-he peripheries of the wheels -12-and'13, 'respectively. By sufficientlyraising the 'removable hand'le ,*-16,i thewheels; 19, can; be

brought into engagement 1:. with the floor, causing-the -wheels, 12 and 13,, to be slightly raised'frdm the floor, as indicated in Fig; 4, while, by' loweringthe l1& 11lletO01 below of the crank-handle; 29, or-' of the crankit the position'shown i-n Figw2ysaid wheels,

19, can be raisedfromthe floor a suflici'entdistance to permit the wheels, 12 a and 13, to

mounted, concentrically with the bearinga'perture which receivesthe neighboring end of the shaft, 4; and said gear-wheel carrles a lug, 32, adaptedtotengage said 'cranka handle; 14, to cause t he"wheel,-12, to rotate in unison-with the beveled -gear 312 Whenthedevice-is used-in this manner, the'h-and-le," 16, is swung upward at A such an angle that tl1e-'wheels,--19,'- engagethe floor, so as "to lift the wheels,- 12 andl3, fIOHTftllQfiOOI;'Tlii;

Whether the brush be operated by means handle, 14, the brush can bre rotated more or less rapidly Without regard to therapidity or direction" of movement -ofthe dustrpam'; The device can thus be moved towardrand" from thebase-board or a piecenof'furnitulfey or rapidly rotated'for as-long timeasrnaybe desired in -eloseproximity to such object while the dust pan, is held stationary.
