Application filed my 10, 1915. Serial No. 39,135.
.To all whom it may concern .Be 'it known that l[, HERMAN WrrKowsKI, a citizen of the United States, residing-at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Floor-Scrapers; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to' make and use the same, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon, which form a part of this specification.
lhis invention relates to new and useful improvements in floor scrapers and comprises a simple and efficient device of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully de? scribed, shown in the accompanying drawings and then specifically defined in the appended claim.
My invention is illustrated in the accom- I panying drawings, in whichg Figure 1 is a perspectlve view of the invention. Fig. 2 is a central longitudinal I so sectional view. Fig. 3 is a plan view of the.
inside of the clamping member A, and Fig. 4 is a like view of the clamping member K.
Reference-now being had to the details of the drawings by lett r, A designates one of the clamping jaws which is provided with a contractedextension B about which pro jects a flange D. The upper surface of said clamping jaw is provided with serrations E and is apertured at F for the reception of the bolt G upon which awinged nut H is mounted. The other jaw, designated by letter K. has a contracted extension K adapted to conform to and engage the contraction upon the other jaw and is held from lateral movement by said flange. 'l[he jaw K is provided with a socket N for the'reception of the handle 0 and has a slotted recess R upon its clamping face adapted for the reception'of the head of said bolt. Said clamping face is provided with transverse serrations C, cooperating with the serrations upon the other jaw to hold the scraping member 'l.
It will be noted that the space intermediate the socket member and the projecting portion of the jaw K is concaved as at Q, and adapted to receive the thumb of an operator holding-the device.
What I claim to be new is A floor scraper comprising a jaw with a corrugated face and provided with a recess with a slot in the wall thereof, a socket for the receptlon of a handle, said jaw being disposed at an angle to the socket and havipg a contracted portion at one side of the latter, 'a second jaw having a contracted en corresponding to the shape of the contracted portion of the other jaw and projaw, a boltcarried by the second referred to jaw and engaglngthe slot and recess in' the other jaw.
In testimony whereof hereunto affix my signature in presence of two witnesses.
