HENRY A. GORE, OF GOSHEN, INDIANA.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 226,847, dated April 27, 1880.

Application filed February 15, 1879.

To all whom it may concern Goshen, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in (larpetSweepers, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure l is a plan view, with the top broken away to show the internal construction. Fig. 2 is a transverse section. Fig. 3 is a detailed view of the levers for supporting the drivingwheels. Fig. lis an end view; Fig. 5, a crosssection of the gear or removable end; Fig. 6,

'a section showing the connection of one end of the brush with the case; Fig. 7, a cross-section of the gear end of the brush.

My invention relates to that class of sweepers in which the revolving brush is operated by driving-wheels; and it consists in the several combinations of devices hereinafter described and claimed.

Referring to the drawings, A A is the casin g of the sweeper. To the inner side of the end A the levers B B are pivoted at a c. Studs b b project from the levers B, to receive the drivin g-wheels C C, and are located in relation to th'e pivots a so that a downward pressure on the casing A swings the levers B and causes the wheels C 'to approach each other.

Arms d are formed on the levers B, which extend upward to receive the ends of the spring e, which may be of wire, as shown, or a simple rubber loop, which tends to draw the arms together.

D is a bail, to which the handle E is attached at one side of the center. The ends of the bail are turned inward, and one of them extends through the casing A ,forming a pivot, upon which the revolving brush Fturns.

One end of the brush-shaft is provided with a friction-wheel, G, which is engaged by the projecting part or rim e of the driving-wheels C, the said wheels being forced into contact with the friction-wheel Gr by the action of the levers B. The peripheries of the wheel() may be roughened or serrated to increase the friction between them and the carpet.

The dust-boxes H are placed on each side of the brush in the casing A, and are soldered or otherwise securelyfastened to the ends, so as to form the bottom of the sweeper-box and to strengthen the sweeper. At the end of the dust-boxes and through the casing A there are discharge-openings, which are provided with swinging pivoted shutters or covers p p, which are raised when it is required to empty the dust-boxes, and which fall and retain their position by gravity when the sweeper is being used.

The ends of the bail D, which form the pivots upon which it turns, are journaled in the adjustable ears or bars l?, .which earsA are provided with slots z' z', through which the fasteningscrews j j pass.

By means .of the slotted bars the bail and brush may be raised or lowered by a vertical adjustment of the ears, and thus secure any desired adjustment of the brush F, so as to make it press heavier or lighter as it passes over the surface of the carpet.

The top of the sweeper, which has heretofore been made removable, I secure permanently to the box, thereby strengthening it and preventing the escape of dust from the sweeper.

The end A is made removable by any suitable means for repairs, cleaning, or oiling, a convenient means being shown, by mortises and tenons, at Fig. 3, in which mode, when the bail is sprung oft', the end'A. is readily removed.

For the purpose of removing the brush when the bail is stiff or stron g, the bail is swung over theprojection o ofthe ear l?, which is of sufficient length to withdraw the pivot end of the bail from the end ofthe brush, when it can be easily removed.

The ear supporting the un geared end of the brush is provided with an inwardly-projecting part, which tits against the sides of the opening through the casing and terminates with a pivot, upon which the brush turns, and the outer face of the ear is provided with a pivot-hole for the end of the bail, as shown at Fig. 6. By this arrangement a stiff bail can be used, which can be sprung out when it is desired to remove it.

When a wire bail is used the projection may be omitted and the bail-hole may be made through the ear, when the end bail can be projected through, so as to form the pivot or axis of the brush, as at the opposite end.

The end of the brush which revolves upon IOO the part h is provided with a metal cup or socket, which forms a short ferrule for the brush, and its center is provided with a hollow projection for the pivot, so as to protect the end of the brush and give the pivot a inetal bearing.

The geared end ofthe brush is provided with a ferrulc-cap, 7c, which has a central hole through it. Against this cap the frictionwheel G is placed. A washer, Z, is then placed as shown in Fig. 7. A screw, n, is then found, which holds all of the parts to the brush and in place. This screw or bolt a has a hollow head, as shown, into which the end of the bail fits, so as to come over the projection o of the ear, which draws it out of the screw or bolt a, leaving the end oi" the brush free.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination ofthe spring c with the levers B and wheelsCC, substantially as shown and described.

2. The handle E and bail D, en tering the end of the brush, in combination with the adjustable ears P and revolving brush F, all conibined substantially as and for the purpose set forth.

3. In a carpet -sweeper, a removable end having the gearing attached thereto, substantially as and for the purpose set forth.

4. The bail D, provided with an extended bent end, forming a pivot for the brush-shaft, in combination with the revolving brush F, substantially as and for the purpose set forth.

5. In a carpet-sweeper, the brush F, with the friction-roller G, in combination with the screw n, provided with central conical hole in its head, and the bail D, substantially as and for the purpose set forth.

6. The ear P, provided with a projection, o, in combination with the bail D, whereby the bent end ofthe bail may be sprung out of the end of the brush, substantially as and for the purpose set forth.
