CARPET-SWEEPER.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed September 20, 1905. Serial No. 279,225.

TO (AN 11.17101) it III/[bl] concern:

Be it known that I, WVILLIAM H. EMMERT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

This invention relates to improvements in carpet and floor sweepers of the class that is especially adapted for sweeping stairs or places where it is desirable to have the brush reach the corners or recesses not ordinarily accessible to the ordinary sweeper of commerce.

The especial object of my invention is to provide a sweeper that can be easily handled, especially in the work of sweeping down steps or stairs, one that can be cheaply manufactured, and in which the gearing can be adjusted to provide for the wear of the brush and other parts.

In the accompanying drawin s, which form a part of this application, Figure 1 is a rear elevation of my improved sweeper. Fig. 2 is a plan view. Fig. 3 is a side elevation, and Fig. 4 is a cross-section on line 4 4 of Fig. 2.

Referring to the details of the drawings, A represents the sweeper-box into which the sweepings are brushed. It is rectangular in cross-section and much longer relative to its width than the ordinary sweeper, it being desirable to have it cover as much as possible of the surface of a step in one movement. To the sides of the box near its rear corners are mounted wheels a, which carry that portion of the box so that it can be moved freely back and forth. The front side of the box is open to receive the brush g, to be described. Hinges (0 connect a flap a with the top of the box along its front edge, and the ends of the box are chamfered to permit the flap to incline downwardly over the brush, as shown in Fig. r, and a flexible strip of suitable material, as c, is secured to the flap, so that it will project forwardly and rest on the bristles of the brush. The bottom a of the box is preferably recessed, as shown, to provide a dust-receptacle and is pivoted to the ends of the box, as shown in Fig. 4. The spindles of the brush extend through the ends of the box and are journaled in slotted plates 9 which are attached to the respective ends of the box by bolts which pass through the slot in said plates and are fixed in the end of the box. On the end of one of the brush-spindles is fixed a sprocket g.

B represents a standard, which is arranged above the top of the box and inclines rearwardly. Secured to the rear side of said standard and extending at an angle there from is a forked arm I), and at points above this arm are two handles 1) b which are formed with hand-grasps at their outer ends. Secured to the lower end of the standard at its front side is a foot-piece in the form of an angle-plate b, in which a slot 5 is provided to receive screws or bolts which engage the top of the box, thus providing an adjustable connection between the box and the standard, as will be seen from Fig. 2.

To the top of the box at the end corresponding to the sprocket g is secured a plate h,formed with a slot h which receives the attaching screws or bolts, and with an upwardlyextending lug h. A rod e is journaled at its outer end in the lug h and carries on said end a sprocket c and on its opposite or inner end a sprocket e A chain f is arranged on the sprockets e g, thus communicating power from the rod to the brush. The inner end of the rod is ournaled' in a lug 1), formed on the plate I).

To the front side of the standard at a point above the arm b is secured a plate I), which is provided with a lug in which is journalcd the spindle of a sprocket c. A chain (Z travels over the sprockets c and c and a crank c is attached to said spindle, furnishing the means by which it and the parts geared thereto may be normally operated.

The use of a sweeper constructed substantially as shown is as follows: The person operating same will stand on a step below the one to be swept and will grasp one of the handles b b" with his left hand and the crank c with his right hand and in some instances will permit the forked brace to bear against his leg to steady the device and assist in pushing it forward. The sweeper will be started at the top of the stairs and moved over the surface of each step from the riser toward the outer edge, so as to cover the entire surface, and the projecting brush will permit it to cover the angles between the tread and riser as well as other portions. The flexible or yielding flap in front serves to clear the brush of dust and also prevents injury to the woodwork with which it comes in contact.

While two handles are shown, it is evident that one may be dispensed with, if desired, as only one can be used at a time in connection with the crank. Adjustment of the plates g h, and bprovides for taking up slack in the chain f and for the changed relative positions of the brush, as will be apparent.

I claim 1. A carpet-sweeper comprising a box, a brush rotatably mounted in said box, a standard secured to the top of said box and having a handle and a brace extending rearwardly therefrom, and means for rotating said brush, said means being mounted on the box and the standard.

2. A carpet-sweeper comprising a box, a brush rotatably mounted in said box and having its spindles journaled in adjustable plates, a standard adjustably secured to the top of the box, a handle and a brace extending rearwardly from said standard, a sprocket mounted on one of the spindles of the brushplates adjustably secured to the top of the box, a rod ournaled in said plates and having a sprocket on each end thereof, a sprocket mounted on the standard, a drive-chain connecting said sprocket with one of the sprockets on the rod, and a chain connecting the other sprocket on the rod with the sprocket on the brushspindle, for the purpose set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
