FLOOR-SCRAPER.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed July 9, 1910. Serial No. 571,204.

To all whom it may concern:

Be it known that I, Gnonon J. KEPPLI1 GER, a citizen of the United States, residing at Dwight, in the county of Livingston and State of Illinois, have invented a new and useful Floor-Scraper, of which the following is a specification.

It is the object of the present invention to improve the construction of the floor scraper shown in my Patent No. 958,929 dated. May 24;, 1910.

One of the primary aims of the present invention is to provide, in connection with the scraper shown in the aforesaid patent, a depth gage which maybe so adjusted as to adapt the machine to cut a thin or a thick shaving and which will furthermore, prevent an undesirably thick shaving being cut from the floor surface in some places and on the other hand, a thin shaving being cut in other places.

lVith the above and other objects in view, the invention consists in the general construction and arrangement of parts shown in the accompanying drawings, in which,

Figure 1 is a side elevation of the machine embodying the present invention. Fig. 2 is a top plan view thereof, a part being shown in section. Fig. 3 is a perspective view in detail of the depth gage of the present invention. Fig. 4 is a view similar to Fig. 3 showing a wheel scraping device.

Inasmuch as the present invention resides solely in the depth gage, a specific description ofthe machine upon which this device is mounted, will not be here given although it may be stated that the body of the machine is indicated by the numeral 5 and the supporting wheels by the numeral 6, the scraping blade of the machine being indi cated by the numeral 7 and being secured upon the body 5 at the front thereof in the manner described in my aforesaid patent.

The depth gage is illustrated as compris ing a U-shaped member the arms of which are indicated by the numeral 8 and the connecting portion by the numeral 9. Each of the arms, at its extremity, is formed with an opening 10 and in applying the gage to the body of the machine, the same is disposed in advance of the body with one arm lying at each side thereof and a pivot bolt 11 is secured through each opening 10 and into the body. Inwardly of the openings 10, the arms 8 are formed, each, with an arcuate slot indicated by the numeral 12 and having a line of extent which is the arc of a circle struck from the corresponding opening 10 as a center.

It is designed that the connecting portion 9 of the gage rest upon the floor surface being dressed, transversely in advance of the cutting edge of the blade 7 and in order that the gage may be held at angular adjustment, set bolts indicated by the numeral 13 are secured through the slots 12 and into the body of the machine. It will be readily understood that by loosening the bolts 13, the depth gage may be swung up or down, bodily, so as to elevate or lower its connecting portion 9 and this adjustment of the gage, together with the adjustment of the blade 7 which may be had independently of the adjustment of the gage, permits of adjustment of the machine to cut a thin or a thick shaving from the floor surface as may be desired. Further it will be observed that the machine when equipped with the gage above described, will, in its action, more nearly simulate an ordinary plane than without the gage inasmuch as the gage and wheel 6 rest upon the floor surface in a common plane whereas the blade 7 has its cutting edge projecting to a greater or less degree below this plane depending upon the thickness of the shaving to be cut. As aconsequence, a shaving of definite thickness will be out by the machine upon forward movement thereof and it will be impossible to so rock the machine forwardly as to cause the blade 7 to remove an undesirably thick shaving.

The wheel scraper shown in Fig. 4: is illustrated as comprising an attaching portion which is indicated by the numeral 1 1 and is formed with a longitudinally extending slot 15 and, at one end, this portion 15 is formed with a laterally projecting wheel engaging blade indicated by the numeral' 16 and having a sharpened scraping edge 17. This blade 16 is curved in the direction of its length or more specifically in a direction transversely of the portion 14 of the scraper and when the scraper is applied to the machine, it is disposed against one side thereof with its edge 17 bearing lightly against the periphery or tread of the corresponding wheel 6 and presented downwardly. The

scraper is held upon the body of the mathis bolt projects through the slot and the face of the portion 1% which is disposed against the side of the body 5 is plane, the device as a Whole may be adjusted, not only toward or away from the Wheel 6, but may also be adjusted angularly so as to present its scraping edge at a more or less acute angle to the Wheel tread. It will be readily appreciated that the scraper constructed and arranged in the manner shown in the drawings, will remove all accumulations of sawdust, chips, and shavings from the Wheel tread and Will consequently insure of level. and even travel of the machine at all times.

\Vhat is claimed is In a device of the class described, the combination With the body of a floor scraping machine, and a scraper blade thereon, of a depth gage mount ed upon the body and comprising a U-shaped member pivoted at the extremities of its arms to opposite sides of the body at the front thereof with its connecting portion extending transversely in advance of the blade, the said arms of the member being formed With slots, and set bolts secured through the slots and holding the member in adj ustment.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
