GRATER Filed Aug. 20., 1929 FIG-6 FIG? INVENTOR F IG'Q Thomas W Bigoney ATTORNEYS Patented Dec. 16, 1930 THOMAS w. BIeoNEY, or PHILADELPNIA, rENNsYLvANrA GRATER Application filed August 20, 1929, Serial No. 387,212.

This invention relates to improvements in kitchen utensils of that type generally used for grating, shredding or flaking vegetables, cheese, chocolate, soap, etc.

The primary object of these improvements is the production of a device which willbe highly efficient in its specific use, and much easier to clean after use than devices now commonly employed fora similar-purpose.

A further important object is to sodesign the device that it may be very economically manufactured.

In carrying out the several objects of my invention I employ a body portion made from sheet metal and attached to a stiff wire frame,

and thus far do not depart from a common practice in the prior art. However, my

method of producing by die-stamping from a sheet of metal, an lntegrally connected series of strongly reinforced transverse members containing cutting edges, and spaced apart by relatively wide smoothsided, rectangular openings, through which the grated material may pass without obstruction, is new to the art.

It is characteristic of devices commonly employed for the purpose specified, that the grated material tends to clog up the relatively small, constricted or irregularly shaped interstices through which the grated material passes. Such devices are not only difficult to use if the material to be grated is somewhat adhesive in character, but ften extremely difficult to clean'after use.

The degree to which the primary objects of my invention are attained by reason of my unique construction, is attested by the fact that, utilizing a device constructed precisely as illustrated in the accompanying drawing, a complete bar of common laundrysoap may be reduced to thin flakes in thirty seconds,

' ing drawing.

after which allparticles of the soap may be removed from the device by striking its lower edge several times against another object,

such as a table top.

The nature of the improvements by means of which my several objects are accomplished, will be evident by reference to the accompany- In this drawing:

Fig. 1 is a plan View of the complete device,

Fig. 2 is a side view of the complete device with a portion cut away ontheline 22 of F 1 F ig. 3 is a somewhat diagrammatic, partial, longitudinal section on the line 3- 3 of Fig.1, illustrating the grating action of the device onthe material indicated in dotted outline, and which may represent a cheese, chocolate, soap, or the like,

Fig. 4'is; an end view looking at the end opposite to the handle, 1

piece of Fig.5illustrates a blank cut from a sheet i of metal, and from which the body portion of the .devicemay be formed by bending operations, and

F'gs. '6 and 7 represent twovof the possible variations in the form of the cutting edges designated as 13a and 13?), respectively;

In 'manufa'cture,'the blanking out of the body portion of the device and most of the necessary bending is produced in one operation. However, to facilitate description, it flat blank is illustrated in Fig. 5, but with all of the necessary cutting out of the metal completed. From this flat form the portions 123 and the portions 15 are bent up at right angles, and the portions 1 1, 14a and 14?) are bent down at right angles. The portions 15 are then crimped around the respective portions of the wire frame 11,.as illustrated in the several figures of the drawing. The completed'device thus presents a series of flanged transverse members 12 of Z-section, with clear, rectangular open spaces 16 between adjacent transverse members. i The flange portions 13 and 14 projecting perpendicularly from the plane of the members 12, and from opposite sides and opposite edges of the latter, serve not only to reinforce and stiffen the members 12 and the device as a whole, but also provide knife-like edges so disposed as to function as grating knives. It is obvious that the relatively wide, open spaces 16, between adjacent members 12, allow the grated material to pass freely through the device, as indicated in Fig. 3, without clogging, and thus without undue forcing. This feature is, of course, also responsible for the extreme ease with which the device may be cleaned after use as above set forth. 1

It is to be noted that the construction and forming of the device as described gives 11;

durability with economic use of material and manufacturing operations.

Although the portions of the WllG frame extending beyond the body of the device may be variously formed, the shape illustrated has been found advantageous in use of the device. Thus, the upper part of the wire frame serves as a handle which may be firmly grasped in one hand While the lower part of the frame acts as a support which may be rested on any convenient surface.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A grater comprising a frame supporting a body portion integrally formed with a series of parallel transverse members separated from each other by substantially rectangular open spaces, and having opposed perpendicular flanges reinforcing said members and forming cutting edges.

2. A grater having side portions affixed to a stiff wire support anda plurality of transverse members of Z-section in spaced relation integral with said side portions, and present ing reinforcing and cutting flanges projecting at right angles to the plane of said members.

Signed at New York, in the county of New York and State of New York this 19th day of August A. D. 1929.
