Description
Dec. 5, 1933. w. F. DEUTSCHER FLOOR CLEANER Filed ,July 18, 1952 Patented Dec. 5, 1933 PATENT ol-Flce 'I UNETED STATES 7 Claims.
My present invention relates to a new and'v improved floor cleaner having the particular advantage of washing and drying a oor or other surface simultaneously and successively, with Va Y. single operation of the apparatus.
One of the objects of my presentinvention is to provide a cleansing apparatus whereby a oor or other surface to be cleaned, is scrubbed with soapy water or other suitable cleansing fluid and is rapidly freed from. the cleansing fluid so that it is left in a dry or practically dry condition when the apparatus moves over it. Another object of the present invention is to provide an apparatus of the character described which can wash a oor, remove the dirty wash water, and can also direct a current of dry air against the washed oor in order to thoroughly dry the same.
A further object of my invention is to provide an apparatus for the purposes aforesaid which will be simple and compact in structure, easy to operateand durable in use. Other objects and advantages of my invention will be pointed out in more detail hereinafter, and will in part be apparent to those skilled in the art to which the present invention relates.
With the above objects in view my present invention consists of the novel features of construction, arrangement, and combination of parts hereinafter described and illustrated in the accompanying drawing. I It is, however, to be clearly understood, that my invention is not limited to the specific embodiment thereof herein described and shown in the accompanying drawing by way of illustration only.
Reference will now be had to the accompanying drawing forming a part of this specification, wherein like reference characters indicate cor-` responding parts throughout the several views..
Fig. 1 is a perspective view of an apparatus constructed in accordance with my present invention, y
Fig. 2 is a side sectional view of the apparatus along the lines 2-2 of Fig. 3,
Fig. 3 is a front sectio Val view along the lines 3-3 of Fig. 2, and
Fig. 4 is a detail view in section.
The apparatus as illustrated in the drawing comprises a casing 10 which is amounted upon suitable wheels 11 and is provided with a bracket 12 to which is connected a handle 13 by means which the carriage may be readily moved upon t e'oor F in any desired direction. The bottom of -the casing 10 is slightly above the surface of the floor. The casing 10 is divided into lateral compartments `14, 15 and 16 of various-sizes.
The compartments 14 and 15 are open at the bottoms thereof while the compartment 16 is closed at its bottom. The compartment 16 communicates with compartment 15. The compartment 14 is provided with a brush B mounted upon a suitable shaft 17 and the compartment 15 is provided with a brush B mounted upon a suitable shaft 18. A brush B" is also mounted on a shaft 19-within the casing 10 in such manner that the bristles of the brush B" will mesh with the bristles of the brush B. The compartment 16 is provided With a trap at the bottom thereof and the bottom wall of said compartment 16 has a plug P by means of which any water in the trap may be drained out when desired. The upper wall of the compartment -16 is provided with a separator 20 communicating with the compartment 16 by means of an opening 21, as illustrated in detail in Fig. 4. The moist air in compartment 16, which is subjected to air suction as hereinafter described, is freed of the moisture in passing over the vanes 22, shown in Fig. 4 and the moisture drips down through perforations in the bottom of the separator 20 into the trap in the compartment 16. l
A motor M, which may be an electric motor of any suitable type is mounted on the casing 10. The shaft 23 of the motor M has two suction devices mounted thereon such as fans S and S', of ,any suitable type, which are enclosed in cas- .ings 24 and 25 respectively. As illustrated in Fig. 3, the shaft 23 is suitably geared to a vertical shaft 26 mounted on the side of the casing 10, as indicated at 27. The shaft 26 is-in turn suitably geared to the shaft18 as indicated at 28. A pinion 29 on the shaft 18 meshes with a gear mounted on the shaft 19. The motion of the motor M is in this mannerI transmitted to the brushes B and B causing the two brushes to be rotated in oppositedirections. While the system of transmission as described and illustrated is preferred, it will be understood that any other suitable means of transmission may be employed with the same effect.
Mounted on .the casing 10 are two tanks T and T' as illustrated in Fig. 1 and Fig. 2. The tank T is provided for holding a supply of clean water which may be mixedwith soap or any other suitable cleanser, and the tank '1" serves as a reservoir for the waste or dirty wash water. The clean liquid tank T is connected by means of the pipe 30 to a lateral pipe 31 within the compartment 14 above the brush B. The pipe 31 is perforated at the bottom thereof, so that the clean washing liquid is allowed to drip in a suitably regulated V for draining off the waste water.
o waste tank T.
manner upon the brush B. The pipe 30 is provided with a suitable valve V by means of which the flow of clean liquid may be regulated and shut off at any desired time. The waste tank T is provided with a pipe 32 which leads into the compartment 16 and extendsinto the trap in the bottom thereof. The top of the tank T is also connected to the fan casing 24 by means of a pipe 33. The tank T may be provided at the bottom thereof with any suitable outlet valve Similarly the separator 20 in the top of compartment 16 is connected to the fan casing 25 by means of a pipe 34. The fan casings 24 and 25 may be provided with outlets O and O' respectively for delivering the exhaust air into the atmosphere.
When the motor is operated and the device is moved forward upon the oor to be cleaned, the oor is subjected to a vigorous scrubbing action because of the rapid revolution of the brush B to which the clean wash water is supplied. Since the bottom of the brush B moves toward the rear of the casing, the dirty Wash water is moved toward compartment l5, where it is raised from the floor by the revolving brush B', and its action is assisted by the suction which is maintained in compartment 15 as hereinafter described. The waste water raised from the floor by the brush B is thrown into the trap in the bottom of compartment 16 by the brush B" which meshes with the brush B'. In order to further ensure the delivery of the dirty wash water into the compartment 16, a longitudinal rod 35 may be provided againstwhich the bristles of the brush B are moved so that the drops of water accumulating on the brush B" are thereby positively thrown in to the compartment 16.
The operation of the motor also actuates suction fans S and S. The suction fan S forces the air out of the top of the waste tank T' and simultaneously produces enough suction in the pipe 32 to drain the water out of the trap in compartment 16 and cause the water to pass into the The suction fan S' draws up air from the compartments 15 and 16 which are in communication with each other and through the separator 20` which connects with the fan casing 25, thereby assisting in the drying of the iloor and the brushes B and BA'.
If desired, the device could be employed with the brush B removed, so that it could be operated'to dry any wet surface. While the device is operating little or no water will collect in the trap in compartment 16, because the suction through the pipe v32 moves most of the Water up through said pipe 32 into the waste tank T'. When, however, the operation of the device is interrupted as for example at the end of a period of use, the water in the `pipe 32 will flow back and collect in the trap in the bottom of compartment 16. Y
I have thus describedA and illustrated a preferred embodiment vof my invention, but it is desired to be understood that numerous changes may be made in the details of constructionl without departing from the spirit of the invention.
