FLOOR SCRAPER Filed May 20, 1937 Patented Mar. 12, 1940 UNITED 'sm'resg 12,193,571 l J y oFFVIc-E f FLooR scimmia- Herman Siemund, Chicago, 111.," assignor to Greenview Manufacturing Company, Chicago, Ill., a corporation of Illinois Application May 20,1937; Serial No. v143,827

2 Claims. (Cl. 15-245) The present invention relates generally' to Scrapers, squeegees and the like, and it has particular relation to an improved curved type scraper or squeegee, which is specially designed and adapted for cleaning low `at surfaces, such as floors and the like, with a push or pull stroke while permitting the operator to remain in an erect or standing position.

One object of the invention is to provide `a l0 curved floor'scraper or squeegee having 'a plurality of flexible wiping blades.

d Another object of the invention is to provide a curved licor scraper or squeegee having a ex' ible wiping blade along all edges or faces thereof. l5 A further object of the invention is to provide a curved floor scraper or squeegee having one or more wiping faces or edges with a'reversible 'handle mechanism, which permits the operator -to manipulate the scraper on either horizontalfwiping face with a pull or push stroketoward or away movement-while standing in substantially anerect position.

Another object of the invention is to provide a curved floor scraper or squeegeehaving a plurality of angular wiping surfaces, viz: horizontal and/or vertical planes, making it especially adapted for cleaning low floor surfaces adjacent corners and highly polished or painted sidewall moldings without scratching or otherwise marring the latter;

Other and further objects and advantages ofi the invention reside in the detailed constructionl Fig. 3 isa cross-sectional view of the scraper or squeegee shown in Fig. 2, the same being taken along the line `3 3 thereof, looking inthe direc tion of the arrows; with the reverse position of the handle mechanism being shown in dotted lines;

Referring nowv in detail to the drawing, ythere is shown in Fig. 1 a curved floor scraper or squeegee UI'II, having a relatively narrow outer arcuate frame memberI I I, provided with a series of longi- .tudinally spaced apertures I3 extending therethrough; a relatively wide flat ,flexible wiping4 blade member I5, made of rubber or other suitable material, provided with a series of apertures Il spaced longitudinally thereof in corresponding 'position to the apertures I3 of the outer arcuate 20 frame member I I; and an inner relatively narrow arcuate frame member I9, provided with a series of relatively short circumferentially extending slots 2l spaced longitudinally thereof in correspondingposition to the apertures I3 and I'I of A25 l the members I-I and I5 respectively.v The inner frame I9 and theouter frame II are made of relatively light, durable, stainless yand/or` non-j corrosive metal.

The flexible wiping blade I5 is adapted to be-30` removably secured or clamped between the outer `arcuate frame member Hand the inner arcuate frame member I9, and when arranged in proper relationship the apertures I3 and I'I and the slots 21v are in perfect radial alignmentfor receiving 235v bolts 23, which are inserted through the front frame memberr I'I and y'securely fastened in the aligned openings by means of nuts 25 threaded to the lprojecting-,ends thereof beyond the inner frame le. It win be noted that the `reiauvely 4o I wideflexible wiping blade yI5 now projects outwardly'- on all sidesl of the arcuate metal frame l members II and I9, thereby providing a flexible wiping edge on-all sides thereofv and in different' horizontal and vertical parallel planes. The 45 purposev of the circumferential slots 2| in the arcuate frame member I9 is to facilitate assembling of the scraperA or squeegee, and to compensate for any slight variation in the arcuate shape of the metal frames II and IQ in the event they .'50 l Mounted centrally oi the back side of the inner yarcuate frame member I9 is a relativelylarge -Ushaped bracket 21, having radially inwardly extending arms 29, provided with aligned open- 55 mounted in reverse position on the shaft 32 between the arms 29 of the U-shaped bracket 21.

A handle receiving hollow socket member 3'! is provided with a transversely extending L-shaped front attaching bar 3Q, having its long arm lllsecured to the outwardly projecting back of the small U-shaped bracket member 35 by means of bolts 43 and nuts 45, and its short armll extending inwardly between the arms 3l ofthe bracket 35 toward the scraper l0. long wooden handle 49, as best shown in Fig. l,

may be inserted in the hollow socket'member 3l to permit ready manipulation of the scraper or sdueegee from an erect or standing position.

As best shown in Fig. 3, the scraper lll-with its concave side adjacent the` operator, is shown with its 'wiping edge 5l maintained in floor engaging o-r operating position. rThe full lineposition of the handle ill' illustrates its respective position when the scraper lil isl being pulled toward the operator, and the dotted line position of the handle 37 illustrates its respective position when the scraper lll is being pushed awayy from the operator,

In Fig. ll of the drawing, the scraper iii is shown with its opposite horizontal wiping ledgev 53 maintained in door engaging or operatingposition, the concave side thereof still being vnext to the operator.A ln this gure the full line position of the handle member 3T illustrates its respective position when the scraper il) is being pulled toward the operator, and the dotted line position of the handle member 3l illustrates its respective position when the scraper lll is being pushed away from the operator.`

The handle mechanism 3l; is suitably braced, or reinforced, as best shown in Figs. l and 2, by a pair of diverging and laterally extending brace rods 55 positioned symmetrically of the arms 29 of the bracket 2l. The brace rods 55 are of angular shape, having their outer ends 51 bent arcuately to conform to the curvature of the inner framemember i9 to which they areto-be secured, and the inner ends 59 are bent backwardly at an oblique angle to the curved louterends thereof to be secured to the shaft 32 mounted adjacent the ends of the arms 29 of the U-shaped bracket 2l. The curved outer ends 51 of the brace rods 55 are secured at spaced intervals to the inner arcuate frame member I9 adjacent the outer ends thereof by means of the bolts 23 and nuts 25. Y

.I Thus, it will be readily seen that the scraper lil maybe operated with either a pull or push movement, and with either its concave side toward' the operator or away from the operator, as desired by merely flipping or reversing the handle 43. By providing the scraper Ill with flex,- ible wiping edges on all faces thereof, the operator not only has a plurality of separate wiping edges, but also has aplurality of angular wiping surfaces for simultaneously cleaning cornersfadjacent theoor and the molding, either on the A relatively right or left side Without necessitating reversing of the handle 49 or turning over the scraper Ill. Obviously, with a plurality of individual wiping surfaces, the ilexible wiping member will give much longer service than if only one side thereof could be utilized for, if one side becomes badly worn, the opposite side may be used exclusively until it becomes worn out. TIhen, too, the provision of a pluralityof wiping surfaces in diiferent planes, together with the reversibility of the han- `dle member 49, enables an operator to change positions easily and quickly when the present position becomes tiresome from constant movement of a single form of stroke, thereby enabling the yoperator to clean a much larger space with "less tiring Yeffort than that heretofore enjoyed by vthe single 4edge type of door scraper device.

Although I have only described one form of the invention, it will be readily apparent to those skilled in the art that the invention is not so limited, but that' various modifications may be made therein without departing fromthe spirit thereof or from the scope of the `appended claims.

What I claim is:` v y 1n Ia reversible sduecgee of `the class described, a pair of arcuate frame members, a wiping element adapted to be secured therebetween having a plurality of wiping edges extending bcyond all sides of said frame members, means for removably securing said wipingv element between said frame members, a frame structure mounted centrally of the back of said inner frame member having a pair of spaced arms projecting rearwardly. on opposite sides of the center of said inner 'frame member, a shaft mounted between the-ends of said spaced arms, a second frame structure having forwardly extending v arms adapted to be pivotally secured to said shaft, a handle receiving member mounted `on the back of said second frame structure for receiving a removable handle, and a pair of brace rods' extending obliquely from the opposite ends of said shaft to a point intermediate the sides of said inner frame member.
