SCRUBBING- AND DRYING- MACHINE.

Specification of Letters Patent.

Patented Feb. 6, 191?.

Application filed May 13, 1914. Serial No. 838,403.

To all whom it may concern:

Be it known that I, MANUEL V ERA, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Scrubbing and Drying Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a machine especially designed for scrubbing and drying floors, and has for its object to provide a machine of this character of generally improved and simplified construction embodying a motor driven scrubbing brush and drying cloth.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents machine complete.

Fig. 2 represents a top plan view thereof, partly broken away.

Fig. 3 represents a longitudinal sectional view through the machine, and

Fig. 4 represents an enlarged fragmental sectional view through the motor driven scrubbing brush and liquid container for moistening the latter.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the side walls of a supporting frame structure for the machine which are' provided with forward extensions 6 adjacent their lower edges. The under edges of the extensions 6 are formed with recesses in which are mounted a pair of vertically slidable bearing blocks 7 provided with cylindrical shanks 8 slidably mounted in the extensions 6. Springs 9 are coiled about the shanks or stems 8 between the blocks 7 and the upper walls of the recesses receiving said blocks for normally retaining the latter in downwardly extended position. A shaft 10 is rotatably mounted in the bearing blocks 7 and a brush 11 is secured thereon between the extensions 6 of the side walls. Outwardly of one of the side or pulley 12 is keyed thereon and is adapted to be driven a side elevation of the I downwardly from the motor shaft 13 by a belt or chain 14 also positioned upon a sprocket wheel or pulley 15 upon the motor shaft 13. A platform 16 connects the lower central portions of the side walls 5 and an electric motor 17 is supported thereon under a suitable hood A covering 19 connects the front vertical edges of the side walls 5 and extends a distance upon the extensions 6 having hinged to its forward edge a cover plate 20 for the brush 11. A shelf 21 is secured to the cover 19 and supports a liquid container 22 removably positioned thereon and held in position by a band 23. A short pipe 24 having a manually operable valve 25 therein connects the liquid container 22 with a horizontally disposed pipe 26 arranged under the cover 19 and directly above the brush 11. The under side of the pipe 26 is formed with perforations through which the liquid from the container 22 drops upon the brush 11 when the valve 25 is open. The side walls 5 are formed in their lower edges and adjacent their front and rear ends with recesses in which are slidably mounted the spring pressed bearing blocks 25 in which are rotatably mounted shafts 26. Rollers 27 are secured on the shafts 26 between the side walls 5. Vertically elongated openings 28 are formed adjacent the forward upper corners of the side walls 5 and bearing blocks 29 are slidably mounted therein and rotatably receive a shaft on which is secured a toothed roller 31. Screws 32 are fitted in screwthreaded apertures formed in the upper wall of the openings 28 and are swiveled at their lower ends in the bearing blocks 29. A roller 33 is rotatably mounted in bearing blocks 34 secured in the side walls 5 adjacent their upper rear corners. Recesses 35 elongated on horizontal lines are formed in the upper rear corners of the side walls 5 and bearing blocks 36 are slidably mounted therein. An adjusting screw 37 is fitted in a screwthreaded aperture formed in the rear wall of the opening 35 and is swiveled in the adjacent ends of the blocks36, whereby the position of the roller 38 which is rotatably mounted in the blocks 36 may be varied as desired. An endless cloth 39 is positioned over the several rollers 27, 31 and 33 and its tension may be varied as desired by adjusting the vertically movable bearing blocks 29.

Under the rollers 33 and 38 the endless cloth 34 travels under'an idler roller 40 arranged to guide said cloth away from the upper end of a liquid receiving receptacle 41 suitably supported upon a shelf 42 carried by the side walls 5. The upper open end of the receptacle i1 is arranged directly under the rollers 33 and 38 so as to receive the water or other liquid wrung from the cloth 39 in passing between said rollers.

A shaft M is rotatably mounted in one side wall 5 and carries a gear wheel l5 meshing with a gear wheel a6 keyed on the motor shaft 13. A pulley or sprocket A7 is also keyed on the shaft 44 to receive a belt or chain 48 also extending over pulleys or sprocket Wheels A9 keyed on the ends of the rollers 31 and 33, exteriorly of the side wall 5. An angular operating handle 50 is pivotallysecured at 51 to the upper portions of the side Walls 5 and is preferably formed with a longitudinal opening through which is extended wires 51 for electrically operating the motor 17 Copies oi this patent may be obtained for five cents each, by addressing the ers rotatably WVhat I claim is:

A machine of the character described comprising a frame structure, a motor mounted in said frame structure, a plurality of rollmounted in said frame, one in each corner, an endless cloth adapted to travel upon said rollers, driving connections between said motor and the rollers, a receptacle supported in the rear portion of said frame, a wringer roller mounted in said frame adjacent to the upper rear roller, spring pressed rollers mounted in the lower front and rear corners of said frame for normally holding the endless cloth in contact with the ground, and means for adjusting the upper front roller for tightening the endless cloth and the driving connection in one operation.

MANUEL VERA.
