7 Claims. 1

This invention relates to improvements in forms for shaping, setting and drying hosiery, such as forms of ther type described and claimed in United States Letters Patent No. 2,306,350, granted December 22, 1942, on an application of John H. Wahlbeck, and No. 2,433,470, granted December 30, 1947, on an application of Arthur S. Mann.

A hosiery drying form of that type comprises a body or foot portion and a detachable toe or end portion, the latter portion being removable and interchangeable with other similar portions of different sizes so that the form may be used with different sizes of hosiery. It has been the practice to heat these forms internally by the passage of steam or the like through suitable pipe connections and this heating means may be extended into the detachable toe or end portion. In either form of construction, it has heretofore been the practice to hold the body or foot portion and the detachable toe or end portion iinassembled relationship by means of dowel pins mounted upon one portion and detachably tting into apertures formed in the other portion. It has been found that with the types of construction heretofore used, the operation has been satisfactory when the forms are new and for a considerable period thereafter but, after the dowel pins have become worn substantially, the detachable toe or end portions are not held firmly in place, with the result that when the hosiery is stripped from the forms, the toe or end portions sometimes become accidentally removed with the hosiery. This causes a considerable loss of time because of the necessity of removing the toe portions from the hosiery and replacing these toe portions on the body or foot portions of the drying forms.

The principal object of the present invention is to provide an improved hosiery drying form of the type referred to comprising improved means for holding the toe or end portions in assembled relationship to the foot or body portions. A further Objectis to provide a hosiery drying form comprising a foot or body portion. and a detachable toe or end portion, one of which portions is provided with a plurality of holes or recesses to be engaged by dowel pins carried by the other portion, the dowel pins being split and rendered expansible and contractible so that they main, tain a tight frictional engagement with the holes in the other portion and may be readily altered after continued use in order to increase their frietional engagement. Other objects of the in-v vention relates to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specication taken with the accompanying drawings in which two embodiments are illustrated. In the drawings,

The form of construction illustrated in Figs. 1 to 4, inclusive, illustrates the application of the present invention to the type of hosiery drying form which is illustrated in said Letters Patent No. 2,433,470. In this embodiment, a hosiery drying form I0 is mounted upon a conduit I l which serves as an exhaust conduit for thev steam which is employed in effecting thel heating of the form- The-formA l0 is somewhat ai in transverse cross section, as illustrated in Fig. 4, and the opposite faces thereof taper toward each other andI terminate in relatively sharp, edges Illa. The

form comprises a standard portion lob provided at its bottom with flanges Ic which conform to the contour of conduit Il to which they are secured by studs I2. Above the standard Ib, there 1s an ankle portion Id which is united with the foot portion Ie. This foot portion carries a detachable end or toe portion i which is of tapered form, terminating in a point Ig.

The parts of the hosiery drying form described above are internally heated by steam supplied from a pipe I4 through a small pipe I5 which extends centrally through a largerpipe I5 embedded in the form and extending throughout the form from the base thereof to a point adjacent the extremity of the foot portion IIIe. The pipe I 6 may be formed of stainless steel or the like embedded in the aluminum, stainless steel or other material of which the parts of the form lll are made. The conduit II is provided with an aperture IIa through which the pipe I5 extends and also with another aperture IIb through which the exhaust steam is returned from the pipe I6 to the exhaust conduit from the interiors of the foot and toe portions.

Adjacent the extremity of the foot portion Ille, o

the pipe I6 enters a hard metal tubular member I 1 which is embedded in the body of the foot portion and which is internally threaded near its extremity for engagement by the threaded end of a tubular cap member I 8 which extends into an aperture I9 formed in the detachable end or toe portion I f. This aperture I9 is of cylindrical form and is tted by a hard metal lining 2B,

formed of stainless steel or the like, and this lining is, in turn, fitted by the tubular cap member I8. The cap member I8 is closed at its outer or upper end by a detachable threaded plug 2l and the small steam supply pipe I extends through the part II into the interior of the cap member I8, terminating adjacent the plug 2|. The steam which is supplied through the pipe I5 is discharged into the tip portion of the cap member I8 and is returned about the pipe I5 within the can member IB and within the parts I6 and l 1' with the result that the ankle portion I 0d, the foot portion Ille and the toe portion IIlf are all internally heated.

The toe or end portion If is held in position on the foot portion Ille by a pair of dowel pins which threadedly engage the recesses I 0h formed in the end of the foot portion and which are adapted to iit into the tubular hard metal members 25 embedded in the toe or end portion IIlf at opposite sides of the hard metal liner 20. The dowel pins 25 are tapered at their ends as shown at 25a and are longitudinally split from their tapered extremities as shown at 251), thus forming two complementary parts 25o which diverge slightly from each other. The dowel pins 25 are formed of hard metal which is resilient and the divergence of the parts 25C is such that they have to be compressed slightly to fit within the tubular liners 26. The tapered parts 25a permit the pins to be readily inserted in the members 26 and the pins have a tight frictional engagement therewith which prevents the accidental withdrawal of the toe portion If during the operation of stripping hosiery from the form. After the dowel pins have become worn with long continual use, a suitable instrument may be inserted in the notches 25h to effect a further spreading of the parts 25o, thus restoring the initial grip of these pins on the members 26 which are embedded in the toe portion.

The form of the invention shown in Figs. 5 to 9,

inclusive, illustrates its embodiment in the type of hosiery drying form disclosed in said Letters Patent No. 2,306,350. This embodiment is illustrated in connection with a portion only of the foot portion 30e and the detachable to'e portion Sf of a form 32 which may be mounted and constructed generally according to the arrangement shown in Fig. 1 except that the drying form 3D is illustrated as being of a hollow formation having opposite sheet metal walls 35g which are a1'- ranged to iorm a structure having a substantially fiat cross section, as shown in Fig. 9, and which are united along one edge as shown at 30h. The opposite walls are preferably spaced apart by an internal member 3| which may be a ilexible cable or the like.

The detachable toe portion 30j has mounted in the base thereof a hard metal block 32 provided with internally threaded apertures in which are secured a pair of dowel pins 35 similar in form to the dowel pins 25 previously described. These pins have tapered extremities as shown at 35a and are split longitudinally as shown at 35h to form two complementary prongs 35o which are ightly divergent and resilient so that they may be compressed when these dowel pins are inserted into cylindrical apertures 35a formed in a block 35 carried by the foot portion 39e. The metal shell or" the toe portion Sf projects beyond the block 32 at one side of the toe portion as shown at 391' and at the opposite side of the form, the metal shell of the foot portion 39e projects beyond the block 3@ as shown at 307, so that when the parts are assembled with the dowel pins 36 engaging the apertures 360., as shown in Figs. 7 and 8, the part 353i overlaps the block 36 and the part 3&7' overlaps the block 32, while the edges of the metal shells of the foot and toe portions abut against each other. There is thus provided a rm connection between the foot portion and the toe portion of the embodiment shown in Figs. 5 to 9, inclusive, and, as in the form of construction previously described, the dowel pins retain a firm grip upon the block 35 even after continued use and may be spread apart after they have been worn to a considerable degree in order to renew their original gripping action.

Although two forms of the invention have been shown and described by way of illustration, it will be understood that the invention may be embodied in various other constructions Without departing from the scope of the appended claims.
