SHEET METAL SPOON Filed Nov. 5. 1928 Patented July 19, 1932 WILLIAM G. MOMBEBGER, OF

BALTIMIORE, MARYLAND, ASSIGNOR TO AMMIDON AND COMPANY, OF BALTIIEORE, MARYLAND, A CGRPGRATION F MARYLAND SHEET METAL SPOON Application filed November 5, 1928. Serial No 317,380.

This invention is a spoon so designed that it may be cheaply constructed of thin sheet metal such as tin plate, and of the type commonly employed for temporary or emergency purposes.

One of the objects of the lHVPIltiOIl is to prOVide a spoon which may be cheapi manufactured of thin sheet metal, but to constructed that all parts will be strongly braced to resist the bending strains imposed upon it while in use. A further object is to provide a spoon of the character ment oned in which the normally weakest portion of the bowl. is

reinforced by the handle in a simple and novel manner.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawing Figure 1 is a to lan v ew illustrat ng a spoon constructed in accordance with the invention. F gure 2 is a bottom plan view thereof. Figure 3 s a longitudinal sectional View. Figure 4 is a transverse sectionai View on the line 4-el of Figure Figu e 5 is transverse sectional View or. the line 5"?) of Figure 1.

Referring to the drawing. A d esignates the handle and B the bowl of a, sheet metal spoon. That portion of the handle which joins the bowl is provided with an arched portion 1 formed on a very sharp curve leading up wardly and reaiwvardly from the interior of the bowl following an appro 'maie true are. and then decreasing h ight from the point marked X tow its f Said arched portion Verted U-shape in cross se tioned to produce 1 sides. as shown in Figure 4-.

The hand e is widened at ts free extrem; ity as indicated at 11. and is provided with a second widened portion 12. located between said free end and the bowL and providing a fulcrum bearing. The top surface of the handle between the arched portion 10. and the portion 11 is continuous. unbroken and flattened as indicated by Figure 5. and provided with approximately vertical depend- 59 ing sides 13. Said sides 13 form continuations of the sides of the arched portion 10, i. e. the sides of said portions 10 and 13 merge into each other, and are inwardly curved to produce narrowed portions 14 and 15 between the portions 11 and 12. The side edges are also provided with a stiffening flange 16 lying approximately at right angles to said vertical sides, as shown. The sides of the bowl are provided with tapered portions 17 which are merged into and become part of flanges 16. It will be particularly noted from an inspection of Figure 3, that the top edge of the bowl merges into the flanges 16 in such a manner that, viewing the spoon in side elevation as shown in Figure 3, said top edge and the bottom edges of the handle as delineated by said flanges 16, form an approximately continuous unbroken line. By this arrangement, the maximum bracing eflect ofthe arch 10 is obtained by avoiding the formation of weak places due to pronounced changes in curvature from the tip of the bowl to the extremity of the handle.

By providing the spoon handle with :the relatively high arched portion 10 of in: verted U-shape in cross section, and equipping the sides of the bowl with the tapered portions 17 connected with the edge flanges 16, the bowl is firmly braced so as to resist bending strain at the intersection of the arched portion of the handle with the interior of the bowl. Experience has demonstrated that small, thin metal spoons heretofore produced may be easily bent and destroyed along a line passing transversely of the bowl at the point of the intersection of the handle with the bowl. By the relatively high arched arrangement described, cooperating with the tapered portions of the bowl which extend into the flanges, the spoon is r gidly braced at its normally weakest part, and will resist very high pressures applied in a manner to bend the bowl, as often occurs with many forms of commercial tin spoons. By tapering the handle from -the arched portion toward the widened free end thereof, so as to reduce the height or thickness thereof with respect to flanges 16, the handle is strongly braced and the widened portions 11 and 12, connected by the curved Lid sides 17 provide a structure of maximum rigidity, and capable of resisting twisting strains. It will also be observed that the flanged portion of the handle adjacent to the end 11 is turned slightly upward from the portion 12 to the free extremity of the handle, so as to cooperate with the tapering of the top of the handle and thereby materially reduce the height of the top of the handle with respect to said flange. In other words, the arched portion is relatively high with respect to the flange but the top surface of the widened portion 11 is of much less height with respect to the flange. It will also be noted that both the inner and outer top surfaces of the spoon present a smooth and continuous unbroken surface from the bowl to the free end.

The advantages of the invention will be readily understood by those skilled in the art to which it belongs. It will be particularly noted that by constructing the parts in the manner described, the bowl is firmly braced and will stand the strains which the material is ordinarily unfitted to resist. By connecting the widened portions of the handle with curved walls having flanges, the handle itself is made very rigid, and the widened portions also provide bearing spaces for convenient engagement by the fingers of the hand while the spoon is in use.

Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1. A spoon constructed of sheet metal comprising an integral bowl and handle, said handle having an arched portion leading upwardly and rearwardly from the interior of the bowl on a sharply curved line following an approximately true arc, the end of said handle which is distant from said bowl being widened and flattened, said arched portion being of U-shape in cross section with unbroken top and sides, and proportioned to have approximately vertical sides, the flat top surface of the rest of said handle being merged into and forming an unbroken continuation of the rounded top surface of said arched portion. and having depending approximatelv vertical sides of less height than th sides of said arched portion, the sides of the arched portion and the sides of the rest of the handle being merged into and forming unbroken continuations of each other, and also extending around the free end of the handle. said handle being widened to provide a fulcrum bearing between its free end and the bowl. the top edge of said bowl and the bottom edges of the sides of said handle, as viewed in side elevation forming an approximatelv continuous unbroken line.

2. A spoon constructed of sheet metal combroken top and sides, and proportioned to have approximately vertical sides, the flat l top surface of the rest of said handle being merged into and forming an unbroken continuation of the rounded top surface of said arched portion, and having depending approximately vertical sides of less height than the sides of said arched portion, the sides of the arched portion and the sides of the rest of the handle being merged into and forming unbroken continuations of each other, and also extending around the free end of the handle, the peripheral edges of said sides having a continuous lateral flange merglng into the peripheral edges of the bowl and disposed at approximately right angles to said vertical sides, the free end of the handle being curved slightly upward but terminating at an elevation lower than the highest part of said arched portion, said handle being widened to provide a fulcrum bearing between its free end and the bowl, the top edge of said bowl and the bottom edges of said flange, as viewed in side elevation, forming an approximately continuous unbroken line.

In testimony whereof I have hereunto set my hand.

WILLIAM G. MOMBERGER.
