- LLIAM HOUSTON,'OF HAVERI-IILL, MASSACHUSETTS CBIE PLATE ATTACHMENT Application filed July 22,

This invention relates to certain'improve- Inents 1n pie-plate attachments of the type which consists ofa metal ring'adaptcd to be removably mounted on the rim of the plate,

and which are primarily advantageous in 7 making pies having a soft filling to hold the dough,'which is built up on the plate, rim, in place until the pie has been baked, after which thering is removed.

More particularly the invention relates to certain improvements on the particular'device disclosed in my Patent-No." 1,699,239, dated January 15th, 1929, which was primarily an improvement over prior devices for this purpose, in that it was adapted to be produced bypassing a strip of thin sheet metal between suitably shaped die rolls, without rupturing the metal, so that the manufacturing cost was greatly reduced as compared with prior devices. 1

While the device of said patent may be pro"- duced at a low manufacturing cost, the re sults secured from its use were found to be unsatisfactory, in that flutes or crimps se-y external diameter of thebead'is substantially greater. at its middle portion than the ex ,ternaldiameter of, the edge portion 6. The top side portion of the beads opposite the cured in the rim of the pie crust built up against it were not of sufiicient depth throughout, and also because the construction did not sufiiciently allow for variations from a supposed standard in the diameters of the plates, which in practice vary quite materially, so that unless the ring fitted the plate rim very closely, the dough would be pressed out between the ring and the platerim, making the results secured so unsatisfactory as to preclude its use.

The primary objects of my present invention are to provide a construction which will manufacture of the construction disclosed in my said patent, and, in addition, will enable the formation of a device of this char acter from a single strip of metal, without causing fracture thereof, which will cause the rim of the pie to be crimped in such a manner that the flutes thereof will be of uniform depth and their sides will extend approxi- 'mately vertically, and the construction will be such that substantial variation in the diameter of the plate from a standard will be 1930. Serial No. 469,714.

RI accomplish these objects by means ofthe construction hereinafter described and asillustrated in the accompanyingdrawings in which I Fig. lis a plan View of a device embodying my present invention, duplicate portions being indicated by dotted lines. r V fFig.2-is a side elevation of a section there- 0 I Figs. 3 and 4 are sectional views at lines 3 and 4-4 respectively of Fig. 2. According to my present invention, I provide a strip a of thin metal of a suitable uniform width, which'isadapted to be bent or molded into the form, now to be described, by passing the same between oneor more into circular form and its ends are lapped and connected'to form a ring. i In accordance with my present invention,

pairs of die rolls, after which the strip is bent I the strip is molded transversely to provide a cylindrically shaped edge portion 5, from which an intermediate transversely semi-circular head 0, projects outwardly so that the;

portion 5, is "extended inward at right an-. gles to, and for a substantial distance within said portion 72, formingaseatingportion d and then the edge'portion 6, beyond the .seat- 7 ing external and internal transversely con- "cave cavities of-- approximately uniform have all of the advantages of economy of depth throughout, the sides of which are approximately perpendicular to the seating portion 03. The flutes areso arranged with reference to the cylindrical edge portion 6 that theinternal cavities open tothe under 'side of the seating portion at .adistance end portions of the strip and spot welding, or otherwise connecting them together, as shown in F1gs. 1 and 2. The internal diameter of the cylindrical portion 5 is made to correspond to a standard diameter of a plate rim, as it, so that it may be readily placed thereon until its seating portion rests on the top side of the plate rim, as indicated in Fig. 3, in which position the fluted portion (2 will extend approximately vertically, although preferably this portion will be formed to extend inwardly at a slight inclination, to permit ready removal after the baking operation has been finished.

This is not, however, a vital. necessity, as in baking the dough usually shrinks sufficiently to permit removal if the sides oi the flutes are vertical.

As the bottoms of the internal cavities open to the bottom side of the seating portion d, within the internal outline oi the cylindrical. portion Z), a substantial seat for engagement with the plate rim will be provided between the bottoms of said internal cavities and the extreme edge of the plate rim. so that, when the dough is built up against the inner side of the rin there will be no opportunity for leakage or the dough over the rim of the plate, and by having the seating portion of substantial width, rings of the same size will be adapted for use on plates which vary somewhat in diameter at their rims.

The bead c is advantageous in that it improves the article by substantially increasing its stiffness, and preventing it from becoming misshapen, or from being bent so as to cause eventual breakage.

The bead c is further particularly advantageous in that it permits the formation of flutes of substantially uniform depth in approximately perpendicular relation to the seating portion (Z, without causing rupture of the metal. by means of the rolls, between which the strip is passed, as by forcing the metal outwardly from the edge portion 7) in a reversely curved formation before the opposite edge portion is drawn inward. bent right angularly and fluted. The strain on the metal at the middle portion of the strip is relieved suflieiently to prevent breakage.

In practice a strip of double width is passed between two pairs. of oppositely disposed die rolls, so that the cylindrical edge portions 7) are formed from the middle portion of the strip, which is split at its middle line, so that two rings are formed simultaneously.

It will be understood that while the fluted pp rt ion is shown as formed in approximately right angular relation to the seating portion, it may be slightly inclined inwardly without departing from the invention.

I claim:

1. A pie plate attachment comprising, a continuous strip of metal bent in circular form and having its ends joined to form a complete ring, one edge portion of the ring being formed cylindrically and adapted to be removably fitted upon the plate rim from its top side, the intermediate portion thereportion and then reversely inward within said edge portion to form a seating portion and the opposite edge portion within said seating portion being bent right angularly thereto andfluted.

2. A pie plate attachment comprising a continuous strip of metal bent into circular form. and having its ends joined to form a complete ring, said ring having one edge portion formed cylindrically and adapted to be removably fitted upon the plate rim from the top side, and having a transversely semicircular bead extending outwardly from said of being extended outward from said edge cylindricalportion, the opposite portion of said head from said portion being extended inwardly beyond said portion, to form a seat for engagement with the top side of the plate rim, and the opposite edge portion of the strip within said seat'being extended right angular-1y upward therefrom and fluted to provide alternating external and internal transversely concave cavities of approximately uniform, depth.

In testimony whereof, I have signed my name to this specification.

WILLIAM HOUSTON.
