' BAKING ANDVMVOLDING DEVICE Filed April 12, 1929 I Patented Nov. 18, 1930 i' L. BAnToiLon Brim-mom, mam s" BAKING Ann MOLDING nnvicn Application filed April 12 The invention has for one of-its ob'ects'to. provide'a mold and corexstructure or-cup pastry making apparatus .ofthe. type especially: designed for the manufacture office cream cones or similar cup pastry, the same being so designed andconstructed and embodying such cooperation of parts, that the waste ofbatteris reduced to theminimum or is entirely'eliminatedflo that perfect cones 'aybemade.-- 1 I -1 Another obect of .the invention is to pro.- duce an improved molding device, whereby such articles may be molded and thenbaked, the improvements consisting mainly" in the E5 provision of an aluminium mold having cast. therein rings of lieavier'andharder metal.- The use of aluminium molds and cores greatly reduces the amount of gas required to heat them to a'bakingtemperatureand in .20 fact the gas required to-heat aluminium molds is aboutone third less than that re.- quired to heat cast iron molds; But the use of all aluminium molds haveiproven very un. satisfactory" because after little usage the aluminium wears 'to such an extent, due to the opening andclosin'g of the molds and the insertion and'withdrawal of the cores, that there is a poor cooperation between the parts.

Ifthe parts do not'cooperate-a large amount of batteris wastedand many imperfect cones are produced. 7 The apparatus constituting the present invention, embodies a female mold and a core of relatively light metal with a'ring of heavin and harder metal cast in the mold and around the core. In its more subordinate'nature the invention includes female mold and core 1 constructed as aforesaid and having means of .keeping the female mold in true 40 alignment, that is, to prevent the'central portionf of a bank of female molds from bending outward, which would allow much batter to ibe wasted. i

Figure 5 is a top sectional view of the female mold showing the reinforcing ringj Figure '6 is av View of the'reinforcing ring and 12 are connected together and then the batter'is poured in any desired way intofthe batter cups 15, 16,17, '18, and 19 thus formed. Insertion ofthe core 14 into the mold sections 11 and 12 serves to force the batter up the inner edges of these sections and thus form the material into the desired cone shape. The

entire 'mold is then carried or movedin any desired way into aheating 'oven or heating furnace (not shown) and j the batter then baked; When the. mold first enters the heating oven it is necessary thatthe batter cups be opened sufficiently to permit the steamgenerated therein to escape. The rapidrai'sing a sectlons and thus becomesan integral: part and lowering the cores in the molds to permit the steam to escape causes excessive deteriora-' 24 and studs having heads 26 on the back side thereof so as to securely fastenthe rings tot-he aluminium molds. By the use of the" dovetail grooves and the studs rings will not become easily detached fromcthe mold. The rings thus securely anchored in place become a permanent part of the mold.

Rings 21 are placed in casting rings or molds and the aluminium'isthen poured into the molds and when the aluminium becomes cooledthe rings of heavier and harder metal are securely fastened to the aluminium mold thereof. a

' Figure 4 shows a core 14 which is provided with iron or' othersimilar metal ring 22 the parts.

' around the core head, Ring22 has a web 23 which passes through the aluminium and thus holding the ring securely in place around the core head. The rings thus fastened to the core become a permanent part of the core.

The rin'gs'22 of iron or other similar metal is placed in a casting ring and the aluminium is poured therethrough and then rammed into the ring. WVhen the aluminium is cooled the rifng's are securely fastenedto the head there- 0 1 To overcome the tendency of the aluminiu molds from bowing outward in the middle there is secured to the sides of the mold section 11 and 12 bars 24 'and 25 by bolts 26, 27 28 and 29 which screw into studs 80, 31', 32, and 33, formed on the sides of the mold sections. I Midway between the studs 30 and 31, '32 and 38 respectively is placed set screws 34: and 35- which may be tightened as much as is necessary to keep the mold sections straight so that there is perfect cooperationbetween :1 -What I-claim is: g
