FLOOR TREATING APPARATUS Filed Oct. 23, 1965 FIGI / ,z 1 /I5 23 IO N 1 WILLIAM B. PRICE United States Patent 3,344,453 FLGQR TREATING APPARATUS William B. Price, 1700 E. Washington St, Bloomington, Ell. 61701 Filed Get. 23, 1965, Ser. No. 503,465 6 Claims. ((11. 15-50) This invention relates generally to apparatus for treating horizontal surfaces such as floors and, more particularly, to machines of the type having a power driven cylindrical treating element rotatable about an axis parallel to the surface to be treated and engageable with such surface to clean and/ or polish the same. In the cleaning of horizontal floor surfaces, it is customary to use liquid agents which are applied to the surface prior to engagement by the treating element.
The primary object of the present invention, is to provide novel surface treating apparatus of the above character which is of simple and inexpensive construction, which is capable of cleaning the surface, removing all liquid used in the cleaning and polishing the surface in a single continuous engagement of the treating element with the surface, which is easy to manipulate, and which is sturdy and durable.
Another object is to provide novel apparatus which is capable of cleaning a surface and removing liquid therefrom without the necessity of complicated suction or wiping devices.
Still another object is to provide novel apparatus in which a single treating element is utilized to perform the functions of cleaning a flat surface, removing a liquid from the surface and buffing or polishing the dried surface.
A further object is to collect the liquid and foreign matter removed by the cleaning element and dispose of the same through the provision of a catcher or collector which is constructed and arranged in a novel manner with respect to the treating element so as to collect the liquid effectively while being easily removed and replaced when full of liquid.
A more detailed object is to collect the liquid on a generally semi-cylindrical member enclosing the cleaning element while being open at the ends to enable the centrifugal action of the element to be utilized to produce a drying air flow across the surface being cleaned.
Other objects and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawings in which:
FIGURE 1 is a side elevational view of novel floor treating apparatus embodying the novel features of the present invention;
FIGURE 2 is a bottom plan view;
FIGURE 3 is a fragmentary sectional view taken along the line 33 of FIGURE 2; and
FIGURE 4 is a fragmentary view similar to FIGURE 1 showing the apparatus under a different condition.
The apparatus shown in the drawings to illustrate the present invention is especially adapted forcleaning the horizontal exposed surface of a floor or a covering therefor by engagement with such surface as the apparatus is moved across the surface. In general, the apparatus comprises a frame, a surface treating element 11 rotatably mounted on the frame, and an electric motor 12 mounted on the frame and having a driving connection 13 with the element. The element is of the cylindrical type which retates about its own axis parallel to the surface to be treated when the periphery of the element is engaging the surface.
In the present instance, the frame is made up of a housing 14 for the motor and two bars 15 and 16 secured at one end to the housing and having their other end porr ce tions extending in parallel with each other and outwardly in front of the housing. One bar 15 is generally straight and is secured to the housing as by bolts (not shown), a spacer -17 being clamped between the bar and the bolts. The other bar 16 is of generally Z-shape with one end portion bolted directly to the housing and the other portion offset laterally and away from the first bar. Stub shafts 18 projecting from opposite ends of the treating element are journaled in suitable bearings supported by the free end portions of the bars. The driving connection 13 herein is a gear belt extending around a slotted pulley 19 on the stub shaft 18 at one end of the treating element and another slotted pulley 20 on the motor shaft which projects from one side of the housing in parallel with the stub shafts.
In accordance with the present invention, the cleaning element 11 is constructed and arranged in a novel manner with respect to the frame and a collecting member 21 to enable the single element to perform, in a single operation and while remaining in engagement with the surface to be treated, the functions of cleaning the surface 10, removing the liquid and foreign matter from the surface so as to dry the surface, and buffing the dried surface. To this end, the element is made up of a plurality of in dividual fiber like members 22 which, during rotation of the element, extend radially and outwardly due to centrifugal force and successively strike the surface being cleaned so as to loosen foreign particles thereon, engage such particles so as to move them along and away from the surface, and dispose of the particles by throwing them upwardly and circumferentially away from the element by centrifugal force. The fiber like members act independently of each other to achieve this result.
The foreign particles and liquid thrown from the cleaning element strike the collector member which extends around the periphery of the element from a point near the floor and adjacent the free ends of the supporting bars 15 and 16 and across the top of the element to a point on the opposite or near side of the element. The collector is radially spaced from the element so as to leave the periphery of the element free of contact with any surface except the surface being cleaned. Such spacing of the collector, from the cleaning element leaves the fiber-like members free to throw off the foreign particles rather than simply push the particles ahead of the members as they move past the collector.
To improve the action of the fiber-like members 22 of the cleaning element 11, at least a portion of the weight of the apparatus is supported directly by the element. Thus, the element projects beneath the frame of the apparatus so as to be in continuous engagement with the surface being treated and there are no other parts adjacent the element to engage the surface and limit the weight carried by the element. It is preferred, however, to provide at least one other support which is spaced from the cleaning element and projects from the supporting frame to engage the surface being treated and support a portion of the weight of the apparatus. Herein, the'additional support is in the form of two small rollers 23 mounted beneath opposite near corners of the motor housing 14 and rotatabe about common axis paralleling and spaced from the axis of rotation of the cleaning element.
While the cleaning element 11 may take various forms, especially satisfactory results including durability have been achieved using a twisted wire brush in which the fiber like members 22 are individual strands of nylon secured between a pair of wires 24 twisted to form helices with the ends of the nylon bristles extending helically around the twisted wire core. With this arrangement, the end portions of substantially all of the bristles are spaced from adjacent bristles so as to act independently thereof and a) -avoid build-up of foreign matter between the bristles due to surface tension resulting from close contact of one bristle with one or more other bristles.
The collector 21, for ease of replacement and disposal, preferably is a single rectangular sheet of absorbent material which may be stiff enough to be self-supporting and retain a shape to which it may be bent or which, as in this instance, is backed by the inner side of a cover 25. This cover is of generally cylindrical contour and of inverted U-shape in cross section and is removably attached to the frame. For this purpose, pins 26 projecting outwardly from the lower front corners of the cover fit into upwardly opening and rearwardly inclined slots 27 on the free ends of the frame bars 15 and 16 and enlarged beads 28 on the rear edge of the cover fit between the legs of upwardly opening U-shaped clips 29 on the front of the housing and the laterally extending intermediate part of the Z-bar.
The absorbent collector sheet 21 lies against the underside of the cover and its rear end fits into clips 30 on the cover. The other end portion of the sheet fits into an upwardly opening recess 31 in the cover on the inner side of the front edge which has been bent reversely and up Wardly for this purpose.
To facilitate manipulation of the apparatus with respect to the surface being treated, an upright handle 32 preferably is pivotally connected at its lower end to the frame. To enable a downward force on the handle to increase the downward force exerted on the cleaning brush 11, the pivotal connection 33 is located on the housing 14 and horizontally between the axis of the supporting rollers 23 and the brush. Also, means is provided for applying cleaning liquid to the surface including a manipulatable member 34 on the upper end portion of the handle for actuating the liquid applicator. In the present instance, the liquid applicator takes the form of a spray nozzle 35 carried by the lower end of a section 36 of flexible tubing mounted on the handle and connected to the outlet of a manually operable pumping device 37 which is connected to a suitable liquid reservoir 38. The pumping device has a suitable connection with the manipulatable member which, herein, is shown as a lever fulcrumed on the handle. When the lever is rocked about its fulcrum, liquid is pumped to the nozzle and dispensed as a spray, the nozzle herein being located above and forwardly from the edge of the cover. A suitable cord and switch means are provided for the motor.
When the motor 12 is deenergized and the apparatus is resting on the supporting rollers 23 and the brush 11, the bristles 22 will be bent and the forward ends of the bars and 16 will be lower than the rear ends as shown in FIG. 1. The spacing of the front edges of the cover 25 and the collector sheet 21 from the floor 10 at this time is very close and depends on the size and strength of the bristles. When the motor is energized and the brush is rotated clockwise as indicated by the arrow in FIG. 3, the front edges of the cover and the collector sheet and the front ends of the bars 15 and 16 will be raised approximately to the position shown in FIGS. 2 and 3 due to centrifugal force in the engagement of the bristles with the floor. The front edge of the collector sheet in this condition preferably is as close as possible to the floor to prevent foreign particles from passing between the sheet and the floor as they are thrown from the periphery of the brush while still avoiding contact of the sheet with the floor.
Each bristle 22 remains substantially straight and disposed in a radial position throughout substantially all of that portion of each revolution when the bristle is not engaging the floor 10. When it first engages the floor, the bristle is bent rearwardly from the radial position and tends to engage the floor with a flailing action. As rotation of the brush continues, the bristle scrapes along the floor and tends to remain in its rearwardly bent position until it moves out of contact with the floor, foreign particles being loosened and carried along with the bristles during the scraping action. As the bristle moves out of contact with the floor, it resumes its radial position with a snap action causing the foreign particles to be thrown ahead of the bristle and circumferentially away from the periphery of the brush. Any foreign particles or droplets of liquid remaining on the bristle tend to be thrown by centrifugal force away from the brush and into the collector 21 during continued rotation of the bristle through the remainder of the revolution and back into engagement with the floor.
To avoid the collection of droplets of liquid on the lower front edge of the collector 21, it is prefered to provide an additional collector bar 39 which is positioned between the floor and this collector edge and closely adjacent the outer ends of the bristles. The bristles thus tend to prevent accumulation of liquid into large drops. Herein, the auxiliary bar is a flat strip secured to and extending along the upwardly and rearwardly bent lower front edge of the cover and lies at a 45 degree angle with respect to the horizontal and the vertical, the lower edge of the bar being closest to the bristles.
Due to the openings at the ends of the collector, the rotation of the brush tends to produce a flow of air not only across the bristles and across the inner surface of the collect-or, but also, across the floor surface beneath the collector. This air flow is believed to be due to centrifugal action resulting from rotation of the brush and prevents air from flowing forwardly beneath the collector sheet.
The improved brush and collector make it possible to utilize the brush not only to loosen foreign particles from the floor and transfer them to the collector along with the liquid cleaner, but also, to buff or polish the floor 3 liquid may be collected on a single absorbent member without complicated suction or storage devices. The efficiency of the brush in effecting the drying action is improved by maintaining the collector sheet out of contact with the periphery of the brush before the brush engages the floor.
