BRUNO SIIVIONIDES, OF MANNHEIM, GERMANY .STOCKING DRYING- AND SHAPING FORM Original application filed August 29, 1927, Serial No. 216,062, and in Germany. December 30, 1926. Divided and this application filed September 12, 1929. Serial No. 391,997.

This invention relates to a stocking drying and shaping form, designed to be heated internally by means of steam, air or other fluid, and over which the stockings are drawn in order to treat them.

The present application is a division of my application Serial No. 216,062, for ironing, shaping and drying apparatus, filed August 29, 1927. 7

It is important in practice that the heat of the heating fluid be distributed uniformly to the walls of the shaping and drying form. The fabric of the stockings must be protected from contact with the fluid and also from excessive heating. The fluid must be highly heated in order to increase the economy of the drying process. 1

It is known to lead the heating fluid into one-half of the interior of the form upwardly and into the other half downwardly. With this method of leading in and out the heator caps of difl'erent lengths may be employed ing fluid, the first half of the form becomes much more highly heated than the second half thereof. The part of the stocking on the more highly heated part, therefore, dries more rapidly and there is then risk of the part already dried beingdestroyed or damaged by the further supply of heat to the hottest point of the form.

One object of the present invention is to provide a form which is so constructed as to be uniformly heated without waste of heat and to effect the uniform drying of the stocki n g applied thereto.

A further object of the invention is to provide a form having a foot portion comprising a fixed heel section and a detachable toe section or cap, with eflicient heating means for said foot portion, whereby toe sections in connection with one and the same form body.

The invention is illustrated in the accompanying drawing, in which:

Figure 1 is a transverse section, on line 1-1 of Figure 2, through a pair of stocking forms and a heat supplying apparatus of one type constructed in accordance with my invention.

Figure 2 is a vertical longitudinal section on the line IIII of Figure 1.

Fig. 3 1s a longitudinal section through a stocking form on an enlarged scale.

Figure 4 is a section on the line IVIV of Figure 3.

Figure 5 is a top view of a detail.

Figures 6 and '7 are, respectively, sections on lines VIVI and VIIVII of Figure 3.

The hollow molds or forms 1 may be made with advantage of sheet iron, aluminum or copper, and are mounted upon a table or plate 2, which is carried on legs 3. The molds or forms may be arranged in transverse rows, of any number to a row. As shown in Figures 1 and 3, the hollow interior of the mold or form 1 is divided by two inner division walls 4 into a number ofcompartments or passages 5, 6 and 7. The compartment 5 forms a central inflow passage between the two other compartments 6 and 7, which serve as outflow passages. The passages 5,6 and 7 are in communication at their upper ends, at or about the pointv of juncture of the leg portion with the foot portion of the form, as clearly shown in Figure 3. The heating fluid to'be used may consist of steam, hot air or gases, as desired. Q

The form is made up of a body or leg portion and a foot portion, and this foot portion is preferably of sectional construction, and comprises a fixed half or heel section 8 and a removable toe sectionor cap 9. The passages 5, 6 and 7 terminate at their upper ends at the point of juncture of the leg portion and heel section of the foot portion of the form, which latter is closed at its outer end by a combined closure and heat transmitting member 10. The inner portion of this member is cup-shaped, or in the form of a flattened receptacle 11, which is intensely heated by the heated fluid flowing from passage "5 to passages 6 and 7. The walls of this cup-shaped receptacle may be ribbed or corrugated to increase its heating area. The member 10 has an intermediate portion or a projecting portion 12, the portion 12 being brazed or otherwise suitably fixed to the part 8. The projecting portion 12 of the member 10 is designed to form a support over which may be fitted the inner end of the removable cap 9, which cap 9 has arranged therein a combined supporting and conducting plate 14; of good conducting material whichis received in the member 10 and serves as a holding element to retain the cap 9 stably in position, while it also serves to transmit heat to the cap from the intensely heatedunember 10. Provision is thus made for heat ing a foot portion of the form uniformly and to a suitable temperature, while providinga cap section which is readily removable so that interchangeable cap sections of different lengths may be employed, allowing one and the same mold to be used for drying and shaping stockings of difierent sizes. ,T he section 9 may be provided with perforations forthe circulation of antherethrough if de sired, and which may be used or not accord ing to conditions. y

In the present instance an air heater is shown for supplying heated air'for heating the. forms. This air heater comprises the tableor plate Qh'aVing openings lfl and 17 therein, the openingslti communicating with thepassages 5 of the forms and-the openings 17 with thepassages-G and-Tofthe forms. Extending along the underside of-thetable or'plate 2 are superposed air chambers 18 and19, separated by a-division wall -20, and

which are in communication atone end through a passage 21 for'med in said division wall. The upper or-supply chamber 18 communicates througlr the openings 16 with the passages 5 of the forms andthe lower'or suction chamber 19 communicates through the openings17 with the passages 6 and Tot-the forms. "In. the chamber '19 ispla'ced -an'elec-' trical resistance heater 22, whichiis pre'ferably disposedbeneath the-opening 21. In the chamber 18 is placeda rotary fan 23 which is'dri-venby a motor 24:- anddraws air-heated by the heating resistance 22 and other air from the chamber 19 and forces themiX-ture of both kinds of airrthrough the chamber 18 into and through the passages 5, 6 and 7 of the forms and thence back through the chamber 19 for re heating and re-circulation. From this it is evident that the air supplied 3 to the forms, deprived of a portion of its heat,

passes back to the air-heater andis re-heated, so that economy'in the use of heat isensured, since the'heating apparatus is only to'generate the equivalent of the amount of heat dissipated, so that the thermal losses are very small.

It will, of course, be understood "that changes in the form, construction and arrangement of parts may be made, within the scope of the appended claims-without departing'from the spirit or sacrificing any of theadvantages of the invention. 7

Having thus described my invention, I claim: r

1. A stocking'drying form comprising-a hollow body portion adapted to receive a heating fluid, a removable toe portion having a supporting plate attached thereto, and a socket formed in said body portion adapted to receive said supporting plate, said socket comprising walls extending inwardly from the endof the body portion and closing said bodyportion, saidwalls being spaced from the walls of the body portion throughout, to provide a "heating ]acket surrounding said socket, whereby the. heating fluid may circulate around all sides of said socket.

2. A stocking drying form comprising a hollow body portion adapted to receive a heating fluid, a removable toe portion having a supportingplate-attached thereto, and a socket 1 formedin said 1 body portion adapted to receive said supporting plate, said socket comprising corrugated walls extending inwardly from the end of thebodyportionand closing said body portion, said corrugated Walls being spaced fromthe walls of the body portion throughout, to provide a heating jacket surrounding said socket, whereby the heating fluid may circulate around all sides of said socket.

In testimony whereof I afiix my signature.
