This invention relates to surface treating means and my improvements are directed to a hand-propelled device which may be provided with two separateV and distinct cleaning implements, which may be brushes having different characteristics, one being a relatively stiff brush for sweeping carpets, and the like, and the other a soft brush for sweeping hard surfaces; or the treating implements may be of suitable character Jfor polishing,
dressing, or otherwise treating ioors or similar surfaces.
ln cleaning or otherwise treating carpets, floors and similar surfaces, it is often desirable to employ diderent cleaning or treating devices on surfaces of different character, or to employ different cleaning devices successively lon the same surface. Thus for sweepingv carpets or rugs it may be desirable to empio)T a fairly stiff brush, whereas for sweeping waxed floors or other surfaces which are apt to be marred by the bristles of a stiff brush it is desirable to employ a relatively soft brush. The Aprincipal object of my invention is to provide an improved means embodying a plurality of such sweeping or cleaning devices, each of which may be rendered operative at will while the remaining device or devices are inoperative.
l n the embodiment of my invention herein illustrated I disclose a sweeper having two rotary brushes one of which may be a soft brush and one a stiff brush. The sweeper is provided with traction members which may be wheels of the usual type, and means are provided whereby either one of the brushes may be connected with the wheels so as to be operated thereby and at the same timey the other brush is disconnected from the wheels 0 and raised from the surface so as to remain idle while the sweeper is moving thereover. The sweeper is providr-d with the usual long handle to move it over the Hoor, and as is the practice with this type of sweeper the 'a handle pivoted to the sweeper body so that, in its operative positions, it may extend from one end or the other of-.the sweeper body. For the purpose of rendering either brush operative, at will, I mount the brushes in such a manner that when the handle is swung from one end of the sweeper body to the other, one of the brushes is moved downwardly into contact with the floor, and being in engagement with the traction wheels is in a position to be operated thereby when the sweeper is moved over Vthe floor. This same movementof the handle lifts the other brush away from contact with the door.
The brushes are preferably mounted on parallel axes, in spaced relation with a dust pan between them, and in the preferred construction the arrangement is such that the.
operative brush is always the forward brush of the sweeper.
My improved sweeper structure includes a casing within which two pairs of traction wheels are journalled, while the respective brushes are disposed within the casing near opposite ends thereof, and respectively beyond the pairs of traction wheels, said brushes carrying circular frictional disks that are adapted to be rotated from the tracl tion wheels with which they are associated.-
The sweeper handle has `a bail which is journalled by pivotal portions thereof in opposite sides ofthe casing, said pivotal portions carrying disks with which are connected links that themselves are pivoted to bars which each have a bearing for a brush and are slotted to receive the axles of the traction wheels. i v
Since the disks are securedl to the bail pivotal portions the swinging movement4 of the handle in one direction causes the bars, which use the traction wheel axles as fulcra, to raise the brush at one end of the casing out of contact with the Hoor surface and to depress the brush at the other end of the casing purpose. Said box, which has a central partition, is adapted to lie between the brushes and has end openings adjacent the brushes to receive dirt, etc., swept up thereby.
Other features r1nd advantages of my invention will hereinafter appear.
In the drawings:
Figure 1 is a horizontal sectional view of my improved surface treating device taken on the line 1 1 of Fig. 2.
Fig. 2 is a side sectional view taken on the line 2 2 of Fig. 1.
Fig. 3 is a sectional view taken on the line 3 3 of Fig. 1.
Fig. 4 is a side sectional view taken on the line 4 4 of Fig. 1, and
Fig. 5 is an endwise section taken on the line 5 5 of Fig. 4.
In said views let 1 indicate a casing adapted to contain the cleaner mechanism and having pairs of traction wheels 2, 3, which are respectively journalled in bearings 4 provided therefor in said casing, said wheels having the axles 5.
The outer cylindrical faces of the wheels are lined with friction material such as rubber, forming the usual traction tires for the Wheels. 6 indicates a handle for the sweeper, which handle is provided at its lower end with a bail or yoke-shaped member 6a pivoted in the side walls of the sweeper casing 1 as shown at 7, and 8 represents the portions of the bail which project inside the casing. Each portion 8 has a collar 9 mounted upon it and secured thereto as by means of a setscrew 10. U-shaped links 11, 12 are pivotally mounted at their upper ends on each disk 13, and said disks are mounted respectively on the projecting portions 8 of the bail and fixed to collars 9. The lower ends of links 11, 12 are pivotally mounted at the inner ends of lever members 14, 15. These lever members have slots 16, 17 by means of which they, are mounted upon the axles 5, of the traction wheels 2, 3, and are capable of rocking thereon. The outer ends of the lever members carry bearings in which sweeping brushes 24, 25 are rotatably mounted.
Each of these brushes is formed of a cylindrical core of any suitable material, carrying bristles. The 'bristles of one of the brushes, as for example brush 24., may be stiff Yand adapted for cleaning carpets, rugs and rough surfaces generally, while the bristles of the other brush 25 may be soft and adapted for sweeping polished or waxed oors and,
smooth surfaces generally.
Projecting from the ends of the cores 24a, 25a of brushes 24, 25, are journals 26, which extend through and are rotatably mounted near the ends of lever members 14, 15, as shown at 27. The bearing 27 is cut away in order to enable the brushes to be removed and replaced easily. Friction wheels 28, 29, made of any suitable material, are secured to the outer ends of the journals 26. The ends 31, 32 of tension springs 30 are secured to the inner ends of lever members 14, 15, and the tension in the springs pulls the lever members inwardly and maintains contact under pressure between the brush friction wheels 28, 29, and the traction wheels 2, 3.
It will thus be seen that by pulling lever members 14 and 15 outwardly, the journals 26 are freed, thereby enabling the brushes' to be removed easily from the casing. The
extent of the outward movement of the mem- -top of casing 1. In Fig. 2, brush 25 is in inoperative position and cam 34 holds fric' tion wheel 29 out of contact with traction wheel 3.
The operation of my improved sweeper is as follows:
As the handle 6 is swung from one end of the body 1 to the other, disks 13 will be rotated. Referring to Figure 2, and supposing the handle 6 to be swung from right to left, turning disks 13 with it, then link 12 will be raised and link 11 lowered, thus lowering the inner end of lever member 14, rotating it about the traction wheel axle 5, pressing friction wheel 28 against cam 33, and pulling lever 14 outwardly along the slot 16. In this manner' the brush 24 vwill be raised from the surface, and at the same time friction wheel 28 will be moved out of engagement with traction wheel 2, and the brush will therefore remain idle during the operation of the sweeper. Similarly, by the same movement of the handle from right to left, it will be seen that brush 25 will be moved into contact with the surface, and into operative engagement with the traction wheel 3. A reversal of the handle will cause the former brush to be moved into operative position and the latter brush into inoperative position.
A dust pan 35 which can be removed and replaced through the top of the sweeper casing 1, has lips 36 which rest on the top 37 of the casing 1, thereby supporting and holding the said dust pan in position. The dust pan has a bottom portion 38, the ends 39 of which are bent upwardly and inwardly so as in such position that its teeth engage with the bristles of the brush. This application is a'continuation in part of my application for sweeper, Serial No. 341,260, iiled February 19, 1929. t Variations Within the spirit and scope o my invention are equally comprehended by the foregoing disclosure.A
