No. 601,628. Paltented'Apr. 5, 1898.

EMILY BRAMHALL BROWNE, OF DEDHAM, MASSACHUSETTS.

CARPET-SWEEPER.

`SPECIFICATION forming part of Letters Patent No. 601,628, dated April 5, 1898.

Application filed November 5 1897. Serial No. 657 ,499 (No model.)

Be it known thatI, EMILY BRAMHALL ,BROWNE, a citizen of the United States, re-

siding at Dedham, in the county of Norfolk and Commonwealth of Massachusetts, have invented a new and useful Improvement in Carpet-Sweepers, of which the following is a specification. j

The object of my invention is to produce a carpet-sweeper which will sweep a carpet close up to the base-board of a room or to the furniture therein without moving the latter.

The invention consists in the combination and arrangement of parts set forth in the following specication and pointed out in the claims thereof.

In the drawings forming a part of this specification like numerals refer to like parts throughout the several views.

In the accompanying drawings, Figure I is a perspective view of my improved carpetsweeper. Fig. 2. is a longitudinal section through the center of the rotary brush, taken on line a a. Fig. 3 is a cross-section taken on line b b, Fig. 2. Fig. 4 is a section, and Fig. 5 an end elevation, of a modified form of brush and casing. Figs. 6 and 7 are detail views of modified forms of the rotary brush.

Referring to the drawings, the frame I, rotary brush 2, driving-wheels 3 3, and frictiondisks 4 4 are all of the well-known construction in ordinary use. It will be observed in this construction that the brush 2 can only be brought as close to the base-board ofrthe room as the driving-wheels and frame will allow. In order to overcome this objection and enable the machine to sweep close to the baseboard, I construct the brush in two parts 2 and 6, the part 2 being inclosed between the driving-wheels 3 3 and the part 6 extending beyond said driving-wheels in such a manner that it may be brought close to the base-board of the room or to furniture therein. I inclose.

the brush 6 in a thin sheet-metal casing 7, formed to receive the dust at 8 8 and provided with slotted ears 9 9, said casing being secured to the frame by thumb-screws l0 l0.

In Figs. 2 and 3 Ihave shown the brush 6 constructed as a separate brush, fastened to the brush 2 by the shouldered screw 11, so

that the brush 6 maybe disconnected from the brush 2, if desired.

In Fig. 6 I have shown a brush of a modified construction, in which the central spindle is in one piece, the bristles being attached thereto in the ordinary manner.

In Fig. 7 I have shown a brush having the fied form of the brush 6, the end being proi vided with bristles rounded out, as shown, and projecting through an aperture l2 in the casing 7, forming a cushion to protect the base-board from being scratched by the casing 7. o f

In Figs. I, 2, and 3 I have shown a rubber protecting-strip 13, secured in the ordinary manner to the frame l and casin g 7. It is obvious that my improved construction may be applied to any of the carpet-sweepers now on the market and in general use.

Having thus described my invention, what I claim as my invention, and desire by Letters Patent to secure, is-

l. In a carpet-sweeper, in combination with the driving-wheels, a rotary brush in two sections, one section inclosed in a frame between two pairs of driving-wheels and the other section projecting beyond the drivingwheels and inclosed in a casing for receiving the dirt, substantially as described for the purposes specified.

2. In a carpet-sweeper, in combination with the driving-wheels, a rotary brush in two sections, one section inclosed in a frame between two pairs of driving-wheels and the other section projecting beyond the driving -wheels and inclosed in a casing, said casing being adjustably secured to the main frame of the sweeper, substantially as described for the purposes specified.
