Fig. 6 is a side elevational view of a carpet sweeper embodying my invention, and

Fig. 7 is a similar View of another form of carpet sweeper embodying my invention.

The carpet sweeper of my invention, shown in the accompanying drawings, comprises a casing I having a top 2 side walls 3-3 and end walls 4--5 secured together in any desired or convenient manner to provide a debris compartment C.

The casing is provided with two pair of wheels 6 carried by

axles

1 and 8 which freely pass through elongated apertures 9 in the side walls 33' of the casing. The

axles

1 and 8 are normally downwardly urged to automatically accommodate the wheels 6 to the surface over which the sweeper is moved, by the outwardly directed, free ends ID of springs H. The springs II are medially secured to the side walls 3-3 by clip members 12 struck up from the side walls, or in any other desired or convenient manner.

In assembling the device, the upwardly directed fork ends l3 of a brush comb strip I4 are snapped under the clip members [2 and then the springs II are secured to said members l2,

thus displaceably holding the brush comb strip M in position against the underside of the top I of the sweeper.

The brush comb strip H! is provided with angularly directed teeth IS.

The lower edges I61 of the side walls 3-3' are centrally recessed at I! to receive the brush roller l8 whose pulleys l9 are juxtaposed intermediate the wheels 6' in peripheral driven contact therewith. The lower edges Iii of the side walls 3-3' are further provided with inwardly directed flanges 20.

The lower edges 21 of the end walls 4-5 of the casing are inwardly directed to provide ledge portions 22 terminating in flanges 23.

A debris tray 24 is removably secured to the ledge portions 22 to close the compartment C and provide a bottom therefor. The tray 24, in the preferred form shown in the drawings, is struck up from a single piece of metal to provide a pair of spaced tray sections 2525' each having an opposed, angularly directed inner wall 26. The tray 24 has a struck up continuous perimeter flange 21 which provides continuous side and outer walls-for the tray sections 25-45.

The flange 21 is extended and outwardly curled along the longitudinal portions of the tray to provide longitudinal beads 28. The flange 21 is likewise extended and curled along one trans- ,verse portion of the tray to provide a transverse bead 29. The tray section 25 is provided with a spring latch member 30 secured thereto in any desired or convenient manner, the free, curled end 3| of the member protruding from the section 25 beyond the transverse bead 29 and spaced therefrom.

The flange 21 along the other transverse portion of the tray is extended and angularly directed to provide a lip portion 32. The extended

portions

28, 29 and 32 of flange 21 terminate a short distance from the respective corners of the tray, providing corner recesses 33 therebetween In using the device, the debris tray 24 is pivotally secured to one ledge portion 22 of the casing and removably secured to the other ledge portion, thus closing the compartment C and providing a sealed, dust-tight bottom therefor. To attain this end, the lip portion 32 is inserted above one ledge portion 22 and then the transverse bead 29 is positioned in the flange 23 of the other ledge portion, the corner recesses 33 of the tray facilitating this operation; spring latch member 30 is snapped over the edge of end wall 4 of the casing, thus removably securing the tray in position. As ledge portions 22 are of the same construction it is immaterial to which of the ledge portions the tray is pivoted. When the tray is in position, the longitudinal beads 28 overlap the side walls of the casing, while the tray sections 25, 25' overlap the flanges of side walls 33'.

The brush roller I8 rotates intermediate the inner walls 26 of the tray sections 25, so that, in operation, the bristles 38 of the brush roller [8 will wipe the upper edges of the inner walls 26, discharging the swept debris into the

sections

25, 25. The brush bristles and walls 26 of the tray sections provide a dust-tight closure for the space between the

tray sections

25, 25; the flanges 20 at the centrally recessed portions I! of the side walls 33' seal the side walls. The bristles 38 of the brush rotate through the teeth l5 of the brush comb M in use, automatically cleaning the brush. I

The contents of the ordinary carpet sweeper are discharged into a bag or sheet of paper which is then closed and deposited in a garbage venient and sanitary method of discharge.

In Fig. 2 there is shown a form of my invention wherein-the casing is provided with the compartment C above described, and with arouate shell members 40 secured to the side Walls 33' of the compartment C in any desired or convenient manner, and forming, with said side walls, chambers 4| within which the wheels 6 may rotate, confining any debris carried upwardly by the wheels, and enhancing the hygienic features of the sweeper.

The brush roller l8 ofthe carpet sweeper 'may be rotatably carried by the handle bail 42.

In the form shown in Fig. 6, the handle bail 42 passes through plates 43 ofbars 44 secured to and spaced from the side walls 3-3' and has camming latching engagement-with protuberances 45 carried by said plates.

In the form shown in Figs. 2 and 7, the handle bail 42 passes through the shell members 40 of the sweeper casing and rotatably supports the brush roller iii, the bail having camming latching engagement with protuberances 46 carried by the shell members 40.

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

1. In a carpet sweeper, a casing having end walls provided with inwardly directed ledges terminating in open channels, and a debris tray provided with an angularly directed lip portion for engagement over either channel to pivotally secure the tray thereto and further provided with a channelled portion for reception within the other channel of the casing to close the bottom of the casing.

2. In a carpet sweeper, a casing having end walls provided with inwardly directed ledges terminating in open channels, and a debris tray provided with an angularly directed lip portion for engagement over either channel to pivotally secure the tray thereto and further provided with a channelled portion for reception within the other channel of the casing, said tray being further provided with means to engage the casing to secure the tray thereto.

3. In a carpet sweeper, a casing having a compartment provided with side walls, and a debris tray removably secured to said compartment, said tray being provided with a continuous perimeter flange, said flange having extended longitudinal beads, said casing and tray being provided with complementary means to pivotally secure the tray to an end wall of the casing and with complementary means to removably secure the tray to the other end wall of the casing in position, with the longitudinal beads overlapping and sealing of the lower edges of the side walls of the casing.

. 4. In a carpet sweeper, a casing having a top, side walls and end walls secured together, inwardly directed ledge portions on the end walls, and a debris tray provided with a lip portion adapted to be inserted over one of said ledge SAMUEL I. BERGER.
