To all whom it may concern:

Be it known that I, AV alter J. Drew, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and 5 State of Michigan, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification.

This invention relates to carpet-sweepers, and has for its objects to provide new and ro 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 15 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 20 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 1 shows a plan view of a carpet25 sweeper 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 30 of Fig. 1. 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 35 threads, &c.

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 40 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 45 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 driv50 ing-wheels AY 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 55 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 60 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 65 the bar or rod B and pivot C 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: 70 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 floor or carpet to receive the sweepings thrown into it by the revolving brush. If the reverse mo- 75 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 sup- 80 porting 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, 8ς 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 90 brush-roller shown in section.

H shows a sectional view of the guard itself.

P shows a plan view of the pintle.

I shows the groove in the end of the brushroller, adapted to receive below the end of the 95 brush-pulley the outer end or periphery of the guard H.

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

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

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 5 and struck up in segmental form, as shown in • the drawings. When 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 io inner surface of the guard and riveted down on the outside of the strip G, as shown at S, thus attaching the pintle P,and also the guard H, to the strip G. It will be evident, however, that this guard H and pintle P may be 15 used in connection with a brush orbrush-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, 20 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 prevent25 ing any clogging of the brush-roller from threads, ravelings, hairs, and such like material. The form or shape of the groove in the brush-roller or brush-roller pulley, as w’ell as the form and shape of the guard, may be 30 varied to suit the construction of the sweeper to which the same is to be attached without departing from the spirit of my invention, the main feature of the invention consisting in having the periphery of the guard extend into 35 the groove, so that the revolution of the brush will carry any threads, &c., outwardly beyond the journal and thereby prevent the winding upon the journal or pintie of any such material.
