Rapids, Mich.,= assignorsto Bissell Carpet Sweeper Company, Grand Rapids, Mich., a corporation of Michigan Application November 17, 1939, Sena-inn. eoaoez 2 Claims. (oils-41) This invention relates to carpet sweepers and particularly to dust pans and dump mechanism therefor.

Heretofore in carpet sweepers having a casin with longitudinally-extending centrally disposed rotary brush, it has been customary to have the pans pivoted adjacent the brush and extend from the brush across the bottom of the casing so that to dump the pans they were swung downwardly away from the side wallsof the casing. This requires considerable space for dumping a carpet sweeper and makes for inconvenience at times.

' ,The objects of this invention are:

First, to provide new and improved dust pans for carpet sweepers.

Second, to provide such'dust pans disposed so that less space is required to receive litter dumped from the carpet sweeper than has been formerly the case.

Third, to provide such dust pans which are pivoted adjacent the bottom of the side walls of the casing and pivot downwardly from across the bottom of the casing,

Fourth, to provide such pans which effectively seal the bottom of the casing when it is closed and which may be easily dumped.

Other objects pertaining to details and economies of construction and operation will appear from the detailed description'to follow. The invention is defined in the claims. Structures embodying the features of the invention are illustrated in the accompanying drawings, in which:

Fig. 1 is a sectional view through a carpet sweeper showing one form of the new and improved dust pans in closed position.

The carpet sweeper l is of'conventional form. Itcons-ists of the casing 2 having

side walls

3 and 4 and end walls 5. A rotary brush 6 extends centrally and longitudinally in the case 15 and its hub 8 is engaged by the rims'ofthe' floor At the bottom of the casing Z are dust pans it which extend from the

wide walls

3 and 4 across the bottom of the casing toward the brush 6'. These dust pans are preferably formed of sheet metal and their outer edges [3 are turned up, as shown, to fit in internally rabbeted portions M in the side walls 31 and 4 when the pans are in closed position. thus sealing the pans against the casing. to'prevent' the passage of litter betweenthe outer edgesof the pans and the pan casing. The inner edges I? of the pansare turned upwardly to form lips to engage stops It. .The stops IE are preferably formed of sheet metal and are rigidly fastened in place exv tending between the end walls'5 of the sweeper 35 parallel-to and adjacent the-brush '6. At the lower ends the sheet metal of the stops. is bent onaa reverse fold I! and a further reverse fold forms a lip I8 to receive the upwardly turned edge l5 of the pans l2. The stops It have an upwardly and outwardly sloping portion l9 which servesxto guide litter to the pans. The stops serve to confine litter in the-pans after it is brushed to the pans over the portions H! by the brush 6.. The upper edges ofhthegstops it are The lower ends are formed with projecting members 2| which fit in apertures 22 in the casing to rigidly hold the stops.

The means for holding the pans in closed position consists of links 23 pivoted to the pans at points 24 which are spaced inwardly from the pivots 25 which pivot the pans to the casing adjacent their outer edges and adjacent the lower edges of the side walls 3 and 4 'of the 8 is a detail View S o the manner casing 2. Spring means 26 are connected to the member 345jon' the end of lever 329.

ber 33 is engaged with the catch 34. The spring member 26 holds the pans resiliently againsttheir stop members I6 so that the sweeper may be used and so that the pans will not rattle or 7 permit dust or litter to leakout of the carpet sweeper.

In Fig. there is shown a slightly modified form of the invention. TheipansJIIZ are pivoted adjacent the side walls I03, 'III4, on the.

pivot I25, as in the form of invention shown in Figs. 1 to 4.;The dumping mechanism consists of the link I23 and the spring member I28 isathesame. The tube III is the same as tube .I I. ,The stop member II 6 is different in that the portion II9 which guides litter to the dust pansfrom the brush is shorter. The stop member I I6 consists of a piece ofsheetvmetal having tubular portions I35 formed ingthe; edges thereof through which rods I36 extend. These; rods are inserted in apertures 131 in the end I05 01 the casing to rigidly hold the stops. edge H5 of the pan is formed with an arc, indicated at I38, to fit the curve of the tubular portions I35'of the stop IIG:

' In Figs. '7 to9 there is shown a different form of stop 2| 6, which has a shorter litterguiding portion 219 and has a tube 235 with a'rod236 therein at the upper end to engage'in an aperture 231. At the lower end a projection 221 is provided to fit in the aperture 222 in the end wall 205 of the casing. I The dust pan 2I2 is of different construction. At its inner edge is the up-turned lip 2I5 corresponding to the lip, l5 of pan I2 in the form of invention shown in Figs-1 to 4. This engages 2| 3 of the pan and the wall of the casing, and

there is no opportunity fordirt or litterto become jlod ged back of the pan when the pan is 4 in closed position. 1

In the form of invention shown in Figs. 1 to4, the lever 29 is apertured at 30 to receive the wire spring member 26. In Fig. 10 there is shown a different form of construction. The wire 3| 6 is provided with a bend 34l which anchors a plate 342 provided with tubular portions 343 centrally of the member 3I6. A key hole type of slot 344 is provided for the platejto engage the" flat The inner' sioning position.

In Fig. 11 there is shown a difierent form of closing means. Springs MS are employed which at one end are pivotally inserted in apertures 424 in the pans 412. A cross member 446 pivotally receives the other end of the spring M6 at 441. A key hole type of slot 444 engages the flat projection 445 on lever 429 H This invention is of considerable practical importance because it makes possible the dumping of the carpet sweeper in materially less space than has heretofore been necessary. The construction is simple and will not easily get out of order. p r
