3 Claims.

rIhis invention relates to certain new and useful improvements in carpet sweepers.

The primary object of the invention is to provide a carpet sweeper embodying floor rollers with a rotaryl brush shiftably journalled between the rollers upon the ends of a handle frame to be shifted by the frame into frictional engagement with the floor rollers at the side of the sweeper forming the leading edge thereof.

A further object of the invention is to provide a carpet sweeper of the foregoing character wherein the iioor rollers have spring mountings for normally holding the sweeper body and brush above the floor. The invention further has for an object the provision of novel dust collection receptacles or pans with manually operable dumping means therefor.

With the above and other objects in View that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings:-

Figure 1 is an end elevational View of a carpet sweeper constructed in accordance with the present inventionn, showing the slotted bearings for floor rollers;

Figure 2 is a vertical longitudinal sectional view taken on line 2 2 of Figure 1, showing the brush roller journalled in the handle frame;

Figure 3 is a fragmentary Vertical longitudinal sectional view taken on line 3 3 of Figure 1;

Figure 4 is a fragmentary end elevational View showing the slotted bearings in the end walls of the sweeper frame for the rotary brush;

Figure 5 is an end elevational View, similar to Figure 1, showing the handle frame shifted to one side and the friction disk at the end of the rotary brush engaged with a floor roller with the forward side of the sweeper body depressed with respect to the iioor roller bearings;

Figure 6 is a cross-sectional view taken on line 6 6 of Figure 2, showing the spring device for holding the floor roller bearings lowered and the sweeper body raised and the spring closing devices for the dust pans;

Figure 7 is a cross-sectional view taken on line 7 7 of Figure 2, of the opposite end of the sweeper body showing the spring device engaged with the oor roller bearings; and

Figure 8 is a fragmentary view, partly in sec- ,tion showing a leg of the handle frame engaged with a notched guard for perpendicular disposition.

Referring more in detail to the accompanying drawings there is illustrated a carpet sweeper comprising a body portion, preferably of rectangular form in plan View and having a top wall Y10 merging into arched side walls 11 and end walls 12, the sweeper bodybeing open at its under side. A pair of non-rotatable shafts 13 extends longitudinally of the sweeper body parallel with the arched walls 11 and respectively at opposite sides of the longitudinal axis of the sweeper body, the ends of the shafts 13 having key-portions 13a extending through upwardly converging slotted openings 14; in the end walls 12 and through simi'- lar slotted openings l5 in guard housings 16 carried eXteriorly of the end walls i2 as shown in Figures 1 and 5. A floor roller 17 is freely rotatable upon each end of the shafts 13 between the key portions 13o within the guard housing 16. The shafts 13 are maintained at the lower ends of the slotsli and 15 with the sweeper body in. an elevated position bymeans of a double spring comprising legs 18 having the outer ends thereof overlying the adjacent ends of the shafts i3 with the intermediate portion of the spring legs 18 anchored to the end wall 12 of the sweeper body by means of al clip 19, this construction being clearly shown in Figures 6 and 7.

A rotary brush 20 is shiftably journalled longitudinally of the sweeper body intermediate the floor wheels 17 at opposite sides of the sweeper body, the rotary brush 20 having the core thereof provided upon each end with a friction disk 2l, the end walls 12 being cut away as at 22 to accommodate the mounting of the brush within the sweeper body. The friction disks 21 are disposed outwardly of the end walls 12 of the sweeper body and within the guard housing 16, the mounting for the rotary brush including a handle frame 23 having side legs 24 bent at right angles thereto with the terminal ends of the legs 24 directed inwardly as at 25 affording journal bearings receivable in the sooketed ends 26 of the brush roller disks 21. The bearing ends 25 of the handle frame 23 extend through arcuate slots 27 in the guard frame 16 and these journal ends 25 also extend through hanger plates 28 overlying the slotted opening 27 and pivoted as at 29 to the guard housing 16. The hanger plates 28 support the handle frame and reduce friction between the ends 25 and walls of the slots 27. The upper edge of the guard housing 16 is flanged outwardly as at 30 intermediate its ends, the flange 3) having a cam edge 31 and an intermediate notch 32 into which the legs 24 of the handle frame 23 are receivable for holding the handle frame and handle carried thereby in a perpendicular position when the carpet sweeper is out of use.

A dust collection pan or receptacle 33 forms a temporary closure for the open bottom of the sweeper body at each side of the rotarybrush 20, the dust pan being hingedly mounted as at 34 at its inner side edges and normally retained in closed positions with the outer edges thereorn engaged with abutment strips 35 as shown in Figures 6 and 7. The devices for holding the dust pans 33 in closed elevated positions and for eiecting opening or dumping movements thereof include a double spring comprising legs 36 having the intermediate portion thereof anchored to a clip 37 upon one end wall 12 of the sweeper body with the outer free ends of the spring legs 36 engaged with lugs 38 carried by arms 39, respectively pivoted at their lower ends as at 40 to a dust pan 33 adjacent its hinge mounting 34, the upper end or each arm 39 projecting upwardly through slotted openings in the arched end walls 11 of the sweeper body and provided upon their extreme upper ends with linger grips 41, the dust pan operating arms 39 being located at one end of the sweeper body.

The normal position of the sweeper when out of service is illustrated in Figure 1, the handle frame 23 being perpendicularly positioned and so retained by the legs 24 of the frame engaged in the notches 32 of the guard housing flanges 30 and when it is desired to use the sweeper, 'the handle frame is moved toward either side wall 11 of the sweeper housing with the legs 24 of the handle frame ulcruming in the iiange notches 32 causing the journal ends 25 of the legs to be shifted in the desired direction and into engagement with a pair of oor wheels 17 at oneside of the sweeper body. The guard plate 28 also shifts upon its pivot mounting 29, remaining in overlying relation with respect to the slot 27 in the guard housing 16. Continued pressure on the handle frame in the same direction disengages the legs 24 of the handle frame from the lange notches 32 so that the handle frameand handle carried thereby may be positioned at the desired angle for use of the sweeper. Forward movement of the sweeper and increased pressure on the handle frame caused the friction disks 21 to be more positively engaged with the associated oor wheels 17 with a tendency to lower the forward side of the sweeper body and also producing increased frictional engagement between the friction disks 21 and the associated floor wheels 17,

this position of the carpet sweeper being illustrated in Figure 5. Dust and dirt collected by the bristles 20a of the rotary duster 29 is delivered into the dust pans 33 and these pans are emptied at will by downward pressure upon the arms 39 to move the dust pans upon their hinge mountings 34. The sweeper body is surrounded by a corded protecting rail 42 and corner rubber buffers 43.

From the above detailed description of the invention, it is believed that the construction and operation of the carpet sweeper will at once be understood, and while there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changs may be made therein without departing from the spirit and scope of the invention as claimed.

We claim:-

l. in a carpet sweeper, a sweeper body, two pairs of resiliently mounted iloor wheels carried by the body, a rotary brush shiftably journalled between the pairs or" wheels, and means for moving the brush into driving engagement with either pair of wheels.

2. ln a carpet sweeper, a sweeper body, two pairs of resiliently mounted floor wheels carried by the body, a rotary brush shiftably journalled between the pairs of wheels, means for moving the brush into driving engagement with either pair of wheels, the means including a handle frame having side legs with bearing ends rotatably supporting the brush, and a notched ange carried by each end of the sweeper body with the legs of the handle frame seated in the notches for normally holding the handle frame perpendicularly positioned and said flange notches constituting a temporary iulcrum for the handle frame in initially moving the rotary brush towards either pair of loor wheels.

3. In a carpet sweeper, a sweeper` body, two pairs of resiliently mounted floor wheels carried by the body, a. rotary brush shiftably iournalled between the pairs of wheels, means for moving.

the brush into driving engagement with either pair of wheels, the means including a handle frame having side legs with bearing ends rotatably supporting the brush, and a hanger plate pivotally suspended on each end of the sweeper body and having a bearing opening therein for the support ofthe adjacent bearing end of the handle frame leg.
