CARPET SWEEPER.

UNITED STATES PATENT CEEICE.

VALTER J. DREW, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO THE BISSELL CARPET SWEEPER COMPANY, OF SAME PLACE.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 621,639, dated March 21, 1899.

Application filed July 2, 1897- Serial No. 643,281. (No model.)

` To @ZZ whom it may concern.-

Be it known that I, WALTER J. DREW, a citizen 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 Carpet-Sweepers, of which the following is a specication.

This invention relates to carpet-sweepers, and has for its objects to provide new and improved means for lowering the dust-pans alternately by rocking the sweeper-case on its pivotal supports, to provide a new and improved construction whereby either dust-pan will be lowered with the sweeper-case at the side which receives dust swept up by the brush in moving the sweeper over the carpet, and to provide a new and improved wheel-supporting device. These objects are accomplished in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which-- Figure l shows an end view of a carpetsweeper constructed in accordance with my invention, the solid lines showing the position of the sweeper-case when the sweeperis moved in the direction indicated by the arrow and the dotted lines showin g the position of the sweeper-case when the sweeper is moved in the opposite direction. Fig. 2 shows an end view of the sweeper-case with the brushsupporting strip or bandremoved in order to illustrate more fully my preferred form of wheel-supports. Fig. 3 is a detail perspective view of the wheel-support.

Similar letters refer to similar parts throughout the several views. The case A of the sweeper may be constructed in any suitable manner and is provided with the bail B. Strips or supports C, extending across the ends of the sweeper-case in the example of my invention illustrated in the drawings, carry pintles H, which form journal-supports for the brush-roller D. As illustrated, the pintles H also afford a pivotbearing Yfor the sweeper-case, by means of which said case may be rocked or oscillated; but it is not essential to my inventionto use the journal of the brush-roller as the pivotal support for the sweeper-case.

D D represent the drive-wheels,of any suitable construction.

E represents what I term the wheel-support, which in the example of my invention shown in the drawings is constructed of wire, but may be constructed of any suitable material, and is provided in its central portion with a loop or eye E', in which is supported the pintle H, and at its ends with arms E2, having journal-bearings E3, in which are supported the journals of the drive-wheels D D. The arms E2 'are placed at an incline, so that the wheel is pressed against the brush-roller when pressure is applied to the sweeper-case through the handle. A Wheel-support E is of course -provided at each end of the case.

F- F represent the dust-pans, which are supported in the case A in any suitable manner and aremoved up and down bythe rocking of the case.

G represents the brush.

In the simplest form of construction I use the journal of the brush-roller as a pivot on which the sweeper-case oscillates; but the sweeper-case may oscillate upon any pivotal support, which pivotal support is in turn su pported by the driving-wheels.

When the sweeper stands upon the iioor or carpet, the driving-wheels support the case, and the case, having its weight supported by the pivots, preferably one at either end, may be rocked readily in either direction by the moving of the sweeper-case backward and forward over the floory by means of the handle of the sweeper, and this rocking motion will alternately lower one pan and then the other pau by the movement of the sweeper. Thus if the sweeper is pushed by the handle in the direction shown by the arrow in Fig. 1 the4 right-hand side of the sweeper shown in such figure will be lowered, carrying with it the pan on that side of the sweeper, and this pan will be in close proximity to the carpet and in position to receive the dust swept into it by the brush-roller. If the reverse movement is given to the case, the other side of the case, with its corresponding pan, will be lowered to receive the dust, and no dust will be swept beneath the pan which is in position to receive the dust while sweeping. The

pans move with the ease and are raised and lowered by the rocking of the ease, as above described.

Having thus described my inventionvhat I claim to have invented, and desire to secure by Letters Patent, is

l. In a carpet-sweeper, the combination of a s\veeper-case, a brush-roller,driving-Wheels, and a pivotal support for the sweeper-case supported by the driving-Wheels for the purpose described.

2. In a earpetsweeper, the combination with the drive-Wheels,brush-roller and dustpans of supports for said drive-wheels having central loops or eyes, and a sweeper-case carrying pintles supported in said loops or eyes, and aording bearings for the brush-roller, substantially as described.

3. In a carpet-sweeper, Vthe combination with the drive-Wheels, brush-roller and dustpans, of supports having at their ends springarms provided with journal-bearings for said wheels and in their central portions loops or eyes, and a sweeper-case carrying pintles supported in said loops or eyes, and affording bearings for the brush-roller, substantially as described.

4. The combination of the driving-wheels, spring-supports upon which the wheels are journaled, brush-roller, sweeper-case having at its ends transverse strips, and pintles or studs carried by said strips engaging with said spring-supports, and also with the brushroller, and affording a pivot-bearin g by means of which the ease may be rocked or oscllated, substantially as described.

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