SPECIFICATION forming part of Letters Patent No. 438,114, dated October '7, 1890.

Application filed July 11, 1890. Serial No. 358,407. (No model.)

To all whom it may concern/.-

Be it known that I, SILAS H. RAYMOND, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Carpet-Sweepers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a noiseless carpetsweeper. My object is to reduce the noise made by and to simplify the construction of articles of this class; and the invention consists in providing an elastic bushing for the journal-bearings, and in the construction, combination, and arrangement of parts, hereinafter described, and particularly pointed out in the claims, reference being had to the accompanying drawings, wherein Figure 1 represents a perspective of a de vice embodying my invention; Fig. 2, a longitudinal vertical section of the same on the line X X of Fig. 1; Fig. 3, an end view with parts broken away to show details 5 Fig. 4, transverse vertical section on the line y y of Fig. 2; Figs. 5 and 6, details of wheels provided with my elastic bushing.

Like letters of reference indicate like parts in each of the several figures.

A represents any suitable case, which is vertically divided into two compartments by a transverse vertical partition A, and has an opening in the top for the removal of the dirt, which is closed by a curtain-top B, secured to a spring-roller B, journaled in the casing, and is provided with a suitable fastening O.

D is a spring-shoe, upon which one end of the casing rides, and has coils D secured to the case by screws E, and a strap F, in which the central portion is vertically movable.

G is the brush-shaft, removably journaled in the casing and is provided with a pulley I-I, secured thereon, grooved to receive the round rubber band or tire I, which engages with the drive-wheels.

K K are dusepans, arranged securely upon each side of the brush-shaft in such juxtaposition as to receive the sweepings.

L L represent the drive or traction wheels, which have the pulley II intermediate and em gage therewith for operating the brush-shaft, and have enlarged central circular openings, in which are the elastic bushings L L of rubber or other suitable elastic material adapted to yield to pressure, which are provided with inner metallic bushings M M, forming the axle or journal boxes for the jour- 6o nals N, which have their bearings in the end of the casing and in the partition A, respectively. The rims of the traction-Wheels en-= gaging the fioor are grooved to fit the round rubber tire I, or, if preferred, the wheels may be provided with a like tire and the rim of the pulley groovedinstead. The elastic bushings L may be of soft material, the rims filling the opening, as shown in Fig. 6, or the rim may be cut away atintervals, forming radial arms in contact with the interior of the opening, as shown in Fig. 5, and secured therein in any suitable manner.

The traction-wheels and pulley are preferably arranged within the smaller compartment within the casing; but it is evident they may be arranged upon the outside thereof in a suitable yoke, if preferred.

Any suitable handle may be attached to the case, preferably having a suitable bail, as shown. The interposition of the rubberbushings L between the journal-bearings and the rims of the driving-wheels deadens the noise accompanying the operation of the sweeper and renders the same practically noiseless. It also enables the axis of the wheel to become more or less eccentric to the rim thereof in response to vertical pressure,whereby the case may rise and fall, yielding to such pressure.

The mode of operation is obvious.

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

1. The combination, with the casing and dust-pans secured therein, of the flexible cur- 95 tam-top B, having the spring-roller journaled 4. The combination, with the casing, the brush-shaft, and drive-Wheels, of the springshoe having at its ends reversed curved loops secured to the end of the casing with the central portion of the shoe above the bottom of the case and free to move vertically in a loop F on the end of the casing, substantially as specified.

In testimonywhereof I aflix my signature in presence of two Witnesses.

SILAS H. RAYMOND.
