XVALTER J. DREV, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO TIIE BISSELL CARPET SVEEPER COMPANY, OF SAME PLACE.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 600,413, dated March 8, 1898.

Application filed July 19,1897. Serial No. 645,089. (Model.)

To all whom it may concern,.-

Be it known that I, WALTER J. DREW, acitizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Oarpet-Sweepers, of which the following is a specification.

This invention relates to carpet-sweepers, and has for its objects to provide new and improved means whereby the sweeper-case can be rocked to lower the dust-pan, so as to receive the dust swept into it by the brushroller, and to provide mechanism for preventing hairs, threads, ravelings, and the like from winding around the journal or pintle of the brush-roller, the same being peculiarly adapted to a carpet-sweeper having a stationary pintle supported in a suitable manner, but also applicable for use in connection with an ordinary journal that revolves with the brush-roller. These objects are accomplished in the manner and by the means hereinafter described and claimed.

Figure l shows a plan view of a carpetsweeper constructed in accordance with my invention, the dotted lines showing the position of the wheel-axles and also the pivoted lever which supports the case from a pivotal point. Fig. 2 is a sectional view on line X X of Fig. l. Fig. 3 is a horizontal sectional view of the brush-roller through the center of the same, showing the part of my invention which relates to the mechanism for protecting the pintle or journal of the brush-roller from threads, (he.

Similar letters refer to similar parts throughout the several views.

I will first describe that part of my invention which relates to the pivotally-supported sweeper-case A. This case is constructed in any suitable manner, and pivotally attached thereto, preferably near the center of the lower surface of the top, is a bar or rod B. The pivot between the sweeper-case and bar or rod is indicated by the letter C, the construction being such that the sweeper-case may be rocked on the pivotal connection. The bar or rod B is provided with links D, connected with the axles R, on which the driving-wheels W are mounted. This construction allows the driving-wheels to press against the brush-roller for the purpose of keeping up frictional contact between said drivingwheels and brush-roller, and these wheels being journaled upon the ends of the axles R they will have a vertical motion with reference to the case-that is, the sweeper-case can be lowered toward the carpet by downward pressure upon the sweeper-handle. Any suitable form of pivot may be used instead of the form shown in the drawings by C, and the bar or rod B may be bent or straight or any other suitable form, provided the same is so constructed as to have an oscillating or rocking motion upon its pivotal point. By placing the bar or rod B and pivot O near the center of the top of the case the case and pans C have a rocking movement, the pans being made rigid with the case.

The operation of my invention is as follows: If the sweeper is pushed forward by the user, the front part of the case, with its corresponding dust-pan, will be lowered toward the door or carpet to receive the sweepings thrown into it by the revolving brush. If the reverse m0- tion is given and the sweeper is drawn in the opposite direction, the other side of the case will be lowered, with its pan, to receive the dust swept up by the brush-roller.

I do not claim, broadly, the pivotal supporti-ng of a sweeper-case so as to allow the rocking movement of the case for the purpose of raising and lowering the dust-pans, inasmuch as the same is claimed in an application executed by me on the 24th day of May, 1897, and filed July 2, 1897.

That portion of my invention which refers to the guard which protects the pintle of the brush-roller is illustrated in my preferred form in Fig. 3, in which E represents the brush-roller shown in section.

H shows a sectional view of the guard itself.

P shows aplan view of the pintle.

I shows the groove in the end of the brushroller, adapted to receive below the end of the brush-pulley the outer end or periphery of the guard H.

F shows the brush-pulley, which in the eX- ample of my invention illustrated in Fig. 3 is made integral with the brush-roller.

Q represents the opening in the brushroller which receives the pintle P.

IOO

I do not Wish to be understood as confining myself to forming the pulley F integral with the brush-roller E.

The guard H is preferably made of metal and struck up in segmental form, as shown in the drawings. lThen a strip is used, as shown in the drawings by G, the pintle P may pass through the guard H and strip G, being provided with a shoulder which bears against the inner surface of the guard and riveted downv on the outside of the strip G, as shown at S, thus attaching the pintle Rand also the guard H, to the strip G. It will be evident, however, that this guard H and pintle P may be used in connection with a lbrush or brush-pulley in sweepers which do not contain the strip G; but I have shown in Fig. 3 my preferred form of using the guard. The guard shown is used in connection with a stationary pintle,

the pintle P not revolving with the brushroller, and any threads or waste that may be wound around the brush cannot reach the pintle or journal P, as the guard would carry them outwardly, thereby absolutely preventing any clogging -of the brush-roller from A threads, ravelings, hairs, and such like maupon the journal or' pintle of any such material.

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

1. In a carpetsweeper, the combination with the case and driving-wheels, of a pivoted bar or rod pivotally supporting the case by an operative connection with the driving-wheels, when said driving-wheels rest upon the floor or carpet, substantially as described.

2. The combination of the case, a bent bar or rod pivoted to the case, driving-wheels journaled on axles, and links D D connecting the said bar or rod to said axles, substantially as described.

3. In a carpet-sweeper, the combination of the brush-roller provided with an annular depression or groove as I, a suitable journalbearing, and a guard having its periphery extending within the groove for the purpose of preventing threads, and the like from Winding around the bearing, substantially as described.

4. In combination with a brush-roller provided With a groove as described, a guard having its periphery extending into the groove, a suitable pintle or journal, a strip as G, and suitable means for attaching the guard to the said strip, substantially as described.

In Witness whereof I have hereunto set my hand and seal in the presence of two witnesses.
