WILLIAM E. WARNER, OF HOUSTON, TEXAS.

FLOOR SURFACER, CLEANER, AND POLISHER.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed December 27, 1909. Serial No. 535,190..

To all whom it may concern:

Be it known that I, l/VILLIAM E. lVAnNnn, citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Floor Surfacers, Cleaners, and Polishers, of which the following is a specification.

My invention relates to new and useful improvements in a floor surfacer, cleaner and polisher.

The object of the invention is to provide a device of the character described for surfacing and cleaning floors of wood of every kind, as well as grinding or polishing those of mosaic, marble or any other composition.

Another object resides in the provision of a mechanism for operating a plurality of cutting rollers which may be applied to the surface to be smoothed either simultaneously or separately.

A further feature resides in the provision of cutting rollers surrounded with resilient cushions which serve as a base for sand paper or some other similar material which is designed to be secured upon said rollers.

\Vith the above and other objects in view, my invention has particular relation to certain novel features of construction and operation an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my complete device. Fig. 2 is a partial plan view thereof. Fig. 3 is a sectional side elevation of the device showing the operative mechanism thereof. Fig. 4 is a partial plan view of the gear mechanism. Fig. 5 is a side elevation of the form shown in Fig. 4. Fig. 6 is a plan view of the foot pedals for operating the device. Fig. 7 is a perspective view of the connecting rods which connect the foot pedals to the operative levers. Fig. 8 is a plan view of the cutting roller. Fig. 9 is a partial sectional end view of the same.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refers to the supporting frame which comprises two suitable side members which are secured together by suitable cross braces.

Numerals 2 and 3 refer, respectively, to conveying Wheels which are designed to support the device and transport the same from place to place. The wheels 2 are [mounted on a suitable steering device i which is operated by hand lever 5, and the wheels 3 are rigidly mounted on shaft (3.

Suitably mounted on the frame 1 is a motor 7 which is designed to provide the motive power for the mechanism.

At both the front and rear ends of the frame 1 transverse abrading rollers 8 and 9 are revolubly mounted. These rollers are not mounted on the frame proper but are secured, respectively, to levers 10 and 11 which are pivoted to the side members 1 as shown in Fig. 1. These rollers 8 and S) are constructed, preferably, of metal and have a resilient covering 12 of rubber or some similar composition so as to provide a yieldable base for the sand paper or other cutting surface. They are further provided with a longitudinal depression 13 extending the full length of the roller upon one side of which a small roller 14 is secured and opposing which is another roller 15 whose cross section presents a cam shaped appearance. These rollers do not project beyond the surface of the abrading rollers and are so disposed, relative to each other, that one edge of the sand paper may be inserted between said rollers 14 and 15 and the body of the paper wrapped around said abrading roller and the other edge also inserted between rollers 14 and 15 and then by a partial rotation of roller 15 the said edges will be gripped between said small rollers and the. paper securely held in place, the roller being held in its proper place by a rack and dog arrangement 16.

Upon the shaft of motor 7 is a gear wheel 17 which meshes with gear wheel 18 which is rigidly mounted on shaft 19 carried by the frame work 1. The shaft 19 also carries a drive gear 20 which meshes with drive chain 21 which in turn meshes with gear wheels 22 and 23 carried respectively, by the shafts of the cutting rollers 8 and 9 and drives said rollers. This chain is held against sagging by means of an idler pulley 24.

The abrading rollers 8 and 9 are partially :inclosed by hoods 25 and 26, which surround the upper portions thereof. The outer portions of these hoods are detachable as is shown in Fig. 3. From the center of these hoods suction pipes 27 and 28 lead, which unite in a common pipe 29. At the upper portion of pipe 29 a suction fan is mounted, from the casing of which a discutting rollers and discharges the sameinto the dust receptacle and is operated by a suitable driving chain or belt connected with the motor 7 as shown in Fig. 1.

For the purpose of elevating and lowering I the abrading rollers I have provided levers 33 and 34 the former of which is fulcrumed at the point 35 and is secured at its forward end to an inverted U shaped member 36,

Which embraces roller 8 and is secured to either end of the shaft thereof. The lever 34 is fulcrumed at the point 37 and is secured at its rearward end to the inverted U shaped member 38 which embraces roller 9 and is secured to the shaft thereof.

Upon the main supporting frame I have mounted the bearing member 39 upon which three foot levers 40, 41 and 42 are pivoted, which in turn are hingedly connected to link 43, stirrup 44 and link 45, respectively. The link 43 is also secured to lever 34 near its free end so that by the depression of the pedal end of lever 40 the free end of lever 34 will be elevated and the cutting roller 9 consequently depressed against the surface to be cut and when said lever is released the cutting roller 9 will be elevated through the operation of spring 46. vBy a depression of the pedal end of lever 42 the free end of lever 33 will be elevated and abrading roller 8 depressed against the surface to be out and when said lever is released the roller 8 will be elevated through the operation of spring 47. The free ends of levers 33 and 34 overlap and are embraced by the stirrup 44 so that when the pedal end of lever 41 is depressed the free ends of levers 33 and 34 are elevated and both abrading rollers depressed against the surface to be smoothed and with the release of lever 41 springs 46 and 47 operate to elevate the said rollers.

The traction mechanism of my device is shown in Figs. 2 and 3. Upon shaft 19 I have mounted a worm gear 48 disposed to mesh with worm gear 49 rigidly mounted on drive shaft 50. This shaft 50 is secured to the supporting frame by bearings 51 and 52 and carries at its free end a bevel gear 53. Slidably mounted upon shaft 6 is a double bevel gear 54 which is keyed on said shaft against rotation but which slides on ball bearings as shown in Fig. 5. A hand lever 55 is pivoted to the main frame and held in any desired position by the ordinary rack and dog arrangement shown in Fig. 3, while the lower end ofsaid lever .55 is hingedly connected to one arm of bell crank 56 the other arm of which operates to slide the gear wheel 54 back and forth. It is obvious that when gear 53 occupies the position shown in Fig. 2 the traction mechanism will be out of gear and the transmission mechanism may be thrown in advance gear or reverse gear by a suitable manipulation of the hand lever 55, 7

It will be observed from the above specifications and the accompanying drawings that I have provided a device of the character described having a plurality of abrading rollers, rotatable in the same direction and having a single driving chain. These rollers are also capable of being elevated and depressed either simultaneously or separately thus permitting either one or both to operate upon the surface to be smoothed, at the will of the operator, features which are not common in this class of machines now in use.
