Claims. (Cl. 15-45) This invention relates to carpet sweepers provided with relatively lixed dust pans and a casing top structure including sections constituting discharge doors for the dust pans.

The main objects of this invention are:

First, to provide a carpet sweeper casing of relatively few parts, which parts may be economically produced and assembled and result in a structure which is strong and `rigid and at the same time attractive in appearance.

Second, to provide a structure having these advantages and provided with two relative iixed dust pans and with two swingably mounted casing top members constituting closures for the dust pans.

Third, to provide a carpet sweeper characterized by the foregoing stated features in which the top casing members constituting the dust pans closures may be readily operated by the foot of the operator if so desired.

Fourth, to provide a carpet sweeper including a pro jecting continuous border frame constituting a supporting seat for the walls of swingable top casing members and provided with a continuous bumper beyond the side and end walls of the casing.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is defined and pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. 1 is a top view of a carpet sweeper embodying our invention with portions broken away and in section to disclose certain structural details, the handle also being broken away.

Fig. 2 is a somewhat enlarged transverse section on a" 'line corresponding to line 2 2 of Fig. 1, the open position of one of the top members being indicated by dotted lines.

.,Fig. 3 is a fragmentary side elevational view partially in vertical section on a line corresponding to line 3 3 of Figs. 1, 2 and 4, the handle being shown in upright posil tion and partially broken away.

j Fig. 4 is a fragmentary view in section on a line corresponding to line 4 4 of Fig. 3.

Fig. 5 is a fragmentary perspective view showing details of the side top casing members and their supporting arms.

Fig. 6 is an inverted view of the bottom casing member.

The embodiment of our invention illustrated comprises a bottom member designated generally by the numeral 1 and including bottom sections 2 2 spaced to provide a ybrush opening extending transversely of the sweeper."

These sections constitute dust pan bottoms and have upturned flanges 3 along their inner edges.

The rirnlike border frame comprising unitary side lmembers 4 and end members 5 are integral with the botftom sections2. These parts are desirably formed as a 'j sheet metal stamping. The side and end members of the border frame have continuous flange-like edge portions 6 and 7 respectively adapted to receive the bumper as will be'llater referred to.

" The end Walls 8 have inturned flanges 9 at their lower 2,885,700 Patented May 12, 1959 ICC edges which are seated upon and lixedly secured to the bottom sections 2 at the ends thereof, see Fig. 2. These end walls bridge the opening between the bottom sections and are provided with downwardly opening recesses 10 adapted to receive the body portion 11 of the brush.

The top of the casing comprises the central top casing member 12 which is iixedly mounted upon the end walls 8 with its ends projecting beyond the end walls and terminating in depending end portions 13 spaced from the end walls.

In the embodiment illustrated the central top member has an upwardly curved intermediate portion and horizontal flangelike longitudinal edge portions 14. The upper edges of end walls 8 are conformed to correspond to the cross sectional shape of this central top member.

In the embodiment illustrated the top member 12 is made up of three sections but when connected they are essentially one integral part. The details of securing the parts together are not illustrated but it will be understood that the parts may be spot welded.

The side casing top members 15 are also desirably formed as sheet metal stampings and are provided with end extensions or inwardly projecting end portions 16 disposed at the ends of the depending end portions of the central top casing member. These casing members 15 have downwardly projecting side walls 17 and end walls 18 formed integrally therewith. The walls seat on the border frame when the members 15 are in closed position, the end walls desirably seating on the bumper 71.

The side walls of these side top sections are inwardly offset and inwardly inclined providing hand holds or foot holds 20, see Fig. 2. The side members are provided with pivot arms 21 of general U-shape secured at 22 to the downwardly projecting anges 23 on the inner edges of the end portions 16 of the top member 15 with the inner arms 24 projecting into overlapping relation to each other to receive the journals 25 of the handle bail 26. These journals 25 are pivotally supported in bearings 27 provided therefor in the end Walls 8.

The journals 25 are iixedly secured to the arms of the handle bail and are provided with downwardly projecting armlike detents 28 which coact with the springable keepers 29 mounted on the inner sides of the end walls. These keepers act to releasably hold the handle in upright position as is illustrated in Fig. 3.

The side top members are spring biased to hold them in both open and closed position by the U-shaped springs 30 one end of which is engaged with the end walls at 31 and the other with the pivot arms 24 at 32. The open position of one of the side members is indicated by dotted lines in Fig. 4 and it will be noted that the attaching point 32 swings across the plane extending through the journals 25 on which the top side members are pivoted and the pivot 31. This pivotal mounting of the sections 15 is concealed. The end members of the central section are provided with stops 33 which coact with the pivot arm 21 to limit the opening movement of the side members.

The brush 11 projects through the recesses in the end walls and is provided with pulleys 34 at the outer sides of the end walls. The ends of the brush body are provided with bearings 35 which are engaged by the journals 36 carried by the springable brackets 37 mounted on the end members of the border frame. The brush is driven by pairs of iioor wheels 38 provided with shafts 40 disposed through openings 41 provided therefor in the end walls, the shafts being yieldably supported and urged against the brush pulleys by the U-shaped springs 42 mounted on the end walls at 43 and having hooked engagement at 44 with the shaft.

Combs 45 are provided to coact with the brush and discharge into the dust pans. As stated, the border frame is provided with a continuous ilangelike rim 6 over which the bumper is engaged,A the bumper being resilient and continuous is effectively retained by its own resilience and projects both at the sidjes and ends of the sweeper.

The parts of our invention may be very economically produced and.v assembled and when assembled results in a relatively light but rigid structure. I

The insetting and inwardly inclination of the side wall of the side top casing members 15 provides an effective hand or foot hold, that is, the casing may be opened for the discharge of the dust pans either by engagement of the swingable top members with tlie foot or the hand. A substantial recess is provided for foot operation as is clearly shown in Figs. 2 and 3. This arrangement of parts 'also provides a distinctive and attractive appearance.

We have illustrated and described our invention in a highly practical embodiment thereof. We have not attempted to illustrate various modifications and adaptations which we contemplate as it is believed lthat this disclosure will enable those skilled in the art to embody oradapt our invention as may be desired.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is: l
