FLOOR-SURFACING MACHINE.

Specification of. Letters Patent.

Patented March 2, 1909.

Application filed March 11, 1908- Serial No. 420,436.

" i machines, and one of the principal objects of the invention is to provide a simple, convenlent and efficient machine for scraping, sandpapering and polishing a floor.

Another object of the invention is to pro vide a machine of the character referred to which shall be mounted upon wheels and propelled manually by means of a handle to scrape, sandpaper and polish a floor.

These and other objects may be attained m; by means of the construction illustrated in the accompanying drawing, in which;-

Figure 1 is a perspective view of a floor surfacing machine made in accordance with my invention. Fig. 2 is a central longitudinal Fig. 3 is a transverse vertical section on the line 3-3 of Fig. 2, looking in the direction indicated by the arrows. Fig. 4 is a section on the line 4-4, Fig. 2, looking in the direction indicated by the arrows. Fig. 5 is a perspective view of the sandpapering and polishing device detached from the scraper and provided with a handle for moving the same over the floor.

Referring to the drawing for a more specific description of my invention, the numeral 1 designates the frame of the machine comprising a rectangular structure having downwardly extending lugs 2 through which an axle 3 projects. Mounted upon the aXle 3 inside the frame is a roller 4, and secured to the roller 4 is a pair of rubber tires 5 seated in recesses in the roller 4. A suitable handle 6 is secured to lugs 7 formed on the rear portion of the frame 1. The front cross bar 8 of the machine frame is inclined relatively to the side bars, and a scraper blade 9 is secured against the front surface of said cross bar 8 by means of suitable screws 10. The front cross bar 8 is pivotally connected to the side bars of the frame upon a pin or bolt 11, said bolt 11 passing through an angular bracket 12, one member of which is secured by screws 13 to the cross bar 8. In order to adjust the proper inclination of the cross bar 8 to properly scrape the floor, set screws 14 are provided, said set screws passing through a bracket 15 and bearing against a block 16 se cured to the rear face of the cross bar 8. To give the required weight to the machine frame a rectangular metal block 17 is provided, said block having a series of lugs 18 on the underside thereof which hold the block 17 into the frame 1 by bearing against the inner walls of said frame. A. plate 19 of the same size as the block 17 is secured on said block by means of suitable countersunk bolts 20, said bolts being fitted with winged nuts 21 underneath the block. Holes 22 in the sides of the block 17 serve for the connection of a suitable handle comprising a yoke 23 having studs upon the ends thereof to fit the holes 22 and a suitable handle bar 24 secured to said yoke.

The operation of my invention may be briefly described as follows WVhen the scraper plate 9 has been adjusted to the required inclination by means of the set screw 14, and the machine arranged as shown in Fig. 1, the floor is thoroughly scraped by pulling the machine over the floor, as will be understood. When the floor is to be sandpapered the block or weight 17 is removed from the frame of the machine, and a piece of sandpaper 25 is placed upon the plate 19 with the side edges of the sandpaper extending between the plate 19 and the block 17. When the winged nuts 21 are tightened the sandpaper is firmly held in place, and the handle 23, 24 is connected to the block 17 and the latter is pushed over the floor to smooth the same. Should it be necessary to polish the floor a piece'of Brussels carpet or other similar material may be connected to the plate 19 in a manner similar to the sandpaper 25 and used to surface the floor, as will be understood.

From the foregoing it will be obvious that a machine made in accordance with my inve ntionis of simple construction, is quick and efficient in operation, can be readily adjusted for various conditions of floors and can be manufactured at comparatively slight cost.

Having thus described the invention, what is claimed as new, is 2* A floor surfacing machine comprising a frame, a handle connected to said frame, a roller mounted in the frame, a scraper adjustably connected to one end of said frame, a block and plate removably mounted upon said frame to serve as a weight to hold the In testimony whereof I affix my signature in presence of tWo Witnesses.

scraper down to the floor, said plate being connected to the block and frame by means of bolts having their heads lying flush with the outer surface of the plate, and Winged l 5 nuts applied to said bolts, said block having Witnesses:
