or PHILADELPHIAVPENNSYL- 'FLAKING :onvrcn Specification of Letters Patent. Patented Ma -"21 1922 Application filedMarch 19, 1921. Serial No. 453,548.

severing portions of a substance from the main body thereof, in the form of extremely thin flakes.

\Ve accomplish this purpose by means of a sheet metal body having a substantially fiat surface and provided in said surface with a series of slits, said slits arranged in lines inclined to the longitudinal extension of the body and also so that the several lines of slits on one side of the medial line of said body converge toward corresponding lines of slits on the other side of said medial line. These slits are so formed that one side wall or margin of each slit is raised above the opposite side wall of said slit and the raised side wall is preferably provided with an angular formation or somewhat sharpened cutting edge.

Referring to the drawings, which illustrate merely by way of example suitable means for the embodiment of our invention:-

Fig. l is a plan View.

Fig. 2 is a side elevation.

Fig. 3 is a section on a. greatly enlarged scale, on line 3-3 of Fig. 1.

Fig. 4 is a similar section on line 3-3 of Fig. 1.

Similar numerals -refer to similar parts throughout the several views.

In the example shown in the drawings, the sheet metal body 5 is mounted on the frame 6 having suitable supports 7 and 8, one at each end. One support, for example 7, is adapted to rest upon a table or other material receiving structure while the other support 8 serves as a handle to be grasped by the operator.

As a preferable construction we have shown the support 7 provided with hook shaped formations for engaging the mar gins of a receptacle wall such as a sinkor tub.

The body portion 5 is provided with a series of slits 9 extending through the same. These slits 9 are very narrow, elongated openings having one long margin 10 raised above the opposite long margin 11 and above the plane of the surface of the sheet 2 metal body 5. These slits 9 are all arranged diagonally or inclined to the longitudinal extension of body 5. i i

' Drawing an imaginary medial line longitudinally upon said body 5, it will be noted that the lines of slits'on each side of said medial line converge toward .each other as shown in Fig. 2, and that alternate lines of slits on either side of the medial, line slightly overlap each other and said medial line.

It will also be noted that/these inclined slits 9 are staggered as to lines parallel with said medial line.

It will also be noted that when striking up one longitudinal margin 10 above the other margin 11 of each slit, the elevated edge is sharpened or of angular formation as shown in Figs. 3 and i to facilitate in the operation to be described. This may be secured for example by taking advantage of the thickness of the sheet metal and slightly turning one edge or corner further out than the other, as shown in Fig. 3, or the thickness of said margin may be reduced in any suitable way.

In operation the device is supported by the supporting part 7 resting, for example, upon a table or other supporting surface, while the part 8 is held in the hand of the operator. The substance to be flaked, such as a cake of soap, is rubbed over the surface of body 5, so that when moved in direction of the arrow Fig. 2, the substance engages with the cutting raised margins 10 of the slits 9 and, due to the fact that the said slits 9 are inclined to the lines of movement of the substance operated upon, and the cutting margins 10 correspondingly inclined, there is a shearing action of said cutting edges upon the substance, with the result that very thin flat flakes or shavings are severed from said cake. of soap, for example, which flakes are carried through said slit-s 9 and deposited beneath the same. The arrangement of the lines of slits, as above de scribed, that is, with all the lines of slits on one side of an imaginary medial line, converging toward corresponding lines on the other side, serves to keep the object operated upon, as it is rubbed over the surface of bod 5, moving substantially along said medial line, so that the maximum efiiciency is secured for all the severing edges or margins of the several slits.

What we claim is 1. In a device of the character describedasheet metal body provided with lines of separated slits inclined to the longitudinal extension of the body ,each line com rising a plurality of said slits formed 'eac with one of its long margins raised above the opposite margin. V

2. In a device of the character described a sheet metal body provided with lines of short separated slits inclined to the longitudinal extension of the body, each line comprising a plurality of said slits formed each withone of its long margins raised above the opposite margin, said raised margin having a sharpened engaging edge. l

In a device of the character described a sheetmetal body provided with a .series of slits arranged in lines inclined to the longitudin al extension of the body and also so that the several lines of slits on one side of the medialline of said bodyconverge toward corresponding lines of slits on the other side of said medial line, said-slits formed each with one of its long margins raised above the opposite margin.

4. In a device of the character described a sheet metal body provided with a series the medial lineof said body convergetoward V corresponding. and slightly overlapping in alternate order lines of slits on the other side of said medial line said slits formed each wlth one of its long margins raised above the opposite margin.
