To all whom it may concern:

Be it known that I, NORMAN J. MAoLnAN, a citizen of the United States of America, residing at Bay City, in the county of Bay andState of Michigan, have invented cer} tain new and useful Improvements in a Cooking-Utensil Cleaner, of which the following is a specification. V

The .present invention is. a scraper or cleaner for culinary purposes and is particularly adapted for removing sticky or burnt substances from culinary utensils.

It is the object of the present inventionto produce a device of the above stated character which is extremely simple in construction, cheap to produce, durable and bodiment of the invention,

fullydescribed and claimed.

ing the cleaner,

effectual in use. With these and other ob jects in view the invention resides in the sundry details ofconstruction, combination and arrangement of parts hereinafter more In this specification. and the annexed drawings, the inventionis disclosed in the form in which it is considered to be' the best; but the invention is not limited to'such form because it is capable of being embodied in other forms, and it is to be understood that iii-and by the claims following the description herein it is intended tocoverthe invention in whatever form it may embody within the scope thereof.

Figure 4 is a transverse-sectional view *akenon line a:w of Figure '31andil1us" trating the cross section 'ofthe wire compos- @Figure 5 is a large fragmentary viewot the coils composing the cleaner; showing two convolutions thereof azndthe position of the sc l'iipin'g edges of the wirecomposing theco., of

Figure "6 is a plan view of anothjerem- Figure 7 is a fragmentaryand enlargedsectional view showmg'the-positionof the scraping edges of the cleaner Figure 6.

Figure 8 is an enlarged fragmentar sectional view taken substantially on line '-B of Figurefi, and v Fi re 9"is a sectional view taken substantially on line A A of Figure 6.

llhe cleaner of this invention is made of'a strand of wire, preferably a single strand, i

provided with a longitudinal scraping edge, the strand being wound in a spiral throughout its length, the spiral being bent 91''- formed in any desired shape for convenient vuse and handling for the purpose of scraping or removingsubstances which have adhered to cooking utensils.

In the forms of the invention shown in the drawings the cleaner G is com osed, preferably, of a single strand of wire 1, substantially triangular in cross section as shown in Figures 4 and 5. However, this invention is not limited to triangular shaped wire as any form of wire will suifice having a longitudinal cutting edge 2. The wire is then wound to form a spiral 1 with the cutting edge 2 1 ing on the outer face of the spiral, see igure 5. Of course, the convolutions of the spiral may be wound close together or spaced apart as may be desired in certain types of cleaners; how

ever, in the-present disclosure it is shown that the convolutions are slightly separated, The spiral thus formed is then bent in desired form or configuration which be of a size and shape to fitin the hand, to be conveniently gripped thereby and provide the ultimate cleaner. However,

as shown in Figure 1, the spiral 1 is coiled upon itself; to produce a. circular form of cleaner having an inner coil 3 and an outer coil 4. In Figure 2, the spiral is bent inan ellipticalor oval ,form having a central longitudinal portion 7 surrounded by the elliptical coil 5. In both forms of the cleaner as-shown inFigures 1 and 2,1 the scraping edge2is on the outer face of each convolution'of the spiral and presents itself to the surface with whichithe convolutionscome in contact. 'Itcan thus be seen that as the cleaner-Cis moved back and forth over a surfacev with a rubbing motion the scraping "edges 2 of, the spiral will remove the sub stances on the surface. The ends. of the spiral are suitably attached or secured to other portions to maintain the form or shape of the cleaner, as indicated at 10 and 11,-

ligures 1 and 2, and 12 and 13, in Fig. v

so other portions of the spiral may y be attached or secured together for'the same purpose, as at 14, in Figure 6. g

It is preferred to form the convolutions of the s iralso thatthey will assume a substantially square shapein cross section, as illustrated'm Figure 3, with the corners of the square slightly rounded as at '6. The principal advantage of so forming the convolution is to increase its area of contact with its surface to be scraped, to produce in effect, by reason of the convolutions being arranged side by side and substantially over: lapping, as shown in Figures 1,2, 3, 6, and 8, a plurality of continuous scraping edges throughout the area of the cleaner, and to permit the corners 6 to reach-into the corners of the utensils, which corners are usually formed with a'rounding edge as illustrated by dotted lines in Figure 3. The form of scraper shown in Figure 6 is some what the same as that shown in Figure 1, except that the wire strand 1 is so arranged and positioned that, by reason of the triangular formation of the wire in crosssection, two of the edges thereof will present beveled or knifelike'scraping edges to lie at an inclination to the surface to be scraped, as clearly illustrated in Figures 7 8 and 9. These inclined cutting edges are indicated at 15 and 16 and alternatively present themselves for a scraping operation as the cleaner is moved back and forth in a manner that will be clearly understood.

- It will be observed that the cleaner of this invention consists of a spirally wound strand of wire, the spiral being coiled or bent upon itself to form a number of lengths or portions arranged side by side and in the same plane throughout the area of the cleaner, thus producing a relatively flat and com-- pact cleaner, with the flat edges of the convolutions of the spiral cooperating to provide cleaning edges across the entire area of From the foregoing it will be seen that by the present invention a very sim leand economical culinary cleaner is r need, there being only a single strand 0 wire involved in this structure but which isof such sha e and form that renders it most efiicient or its purpose.

l aving; thus described my invention in the embodiment in which it is at present devised, what I claim as new and novel and desire to obtain Letters Patent for is:

1. A culinary cleaner comprising a body member formed from a strand of wire wound to form a spiral having re lar and substantially rectangular convolutions, corresponding sides of the said convolutions lying in the same 'plane.

2. -A culinary cleaner comprising at least one, strand of wire wound to form a spiral, having substantially rectangular convolutions having corresponding sides lyin in the same plane, the said spiral being nt upon itsel compact body, the said bent or looped portions of the'spi'ral being secured together to maintain the shape of the body, the outer faces of the said convolutions of the spiral each having a scraping edge thereon and the outer corners of the convolutions being rounded.

3. A culinary cleaner composed of a wire strand having a flat surface extendin longitudinally of the strand, said stran being wound to forma spiral, and said spiral being coiled upon itself to form a substantially Hat and compact body member, to be gripped by the hand, said fiat surface of the wire lying on the outer surface of said body to provide scraping edges and. to present itself to surfaces with which the cleaner contacts.

In testimony whereof I have afiixed my signature.
