FIBER OR LIKE PLATE.
Application 'filed October 13, 1922. Serial No. 594,239.
To all whom it may concern:
. Be it known that I ANDREAS Borne, a citizen of the United tates, residing at Oreland, in the county of Montgomery and State a of Pennsylvania, have invented a new and useful Improvement in Fiber or like Plates, of which'the following is a specification.
' The principal object of the present invention is to provide a fiber or like plate which shall be firm and strong and rigid and which shall present an even or smooth surface and in which the annular wall ofthe bowl shall be steep or abrupt enough to facilitate taking up food, as ice-cream, upon a spoon or upon the side edge of a fork. Other objects of the invention will appear from the following description of the invention which will be claimed at the end hereof and which will be first described in connection with the embodiment of it chosen for illustration. in the accompanying drawing forming part hereof and-in which- V Figure 1 is a top or plan view of a plate embodying features of the invention.
Fig. 2 is a transverse sectional view taken on the line 2-2 of Figure 1, although it may be considered as being taken on any diameter of the plate, and
Fi 3 is a sectional view similar to Fig'. 1 m but (liawn upon an enlarged scale and showing ohly a portion of the plate.
he annular wall of the bowl, generally indicated at 1, is steep in order to facilitate taking up food on a spoon as distinguished from pushing the food along the plate and onto the rim 2 with a spoon. The annular wall of the bowl includes fibers more widely spaced than in the rest of the structure and this attenuation permits of the described steepness of the wall 1 and also insures the presence of a smooth surface. This spaced condition of the fibers is accomplished by the application of. heat, moisture and pressure. The bottom portion 3 of the bowl is convex from the wall 1 toward its center. To illustrate this the legend 3 appears in Fig. 3, but the number of degrees is notessential and may be varied. The. legend 10 similarly indicates the general angle of the rim 2, but the number of degrees in this case is not important and may be increased or diminished. The rim portion 2 may be convex from the wall 1 and from its edge toward its center line as appears by reference to the broken line in Fig. 3. Generally stated, the plate is of 'ogee form' throughout a crosssection of its bowl and rim portions. upon any diameter and in this way rigidity is provided because fiber or paper in fiat or sheet form lacks rigidity and this form together with the described re-arrangement or attenuation of the fibers in the wall -1 insures aneven or fiat surface throughout. In similar cases the rim 2 may be made fiat.
A fiber or like plate having a rim, an annular wall and a bowl, the said wall being steep and fabricated of fibers more. widely spaced or separated than in-the remainder of the structure, the bottom of said bowl and the 7 said rim bein convex on any cross-sectional line to provi e rigidity.
