4 Claims.

'I'his invention relates to an improvement in hosiery forms and more particularly to a hosiery form consisting of unitary leg and foot portions, said form being made from a tube of celluloid or other moldable material by expanding the tube through the introduction of steam, air or other fluid while permitting a longitudinal contraction thereof, and to means for displaying the same.

The object of this invention resides in the provision of a hosiery form constructed from such a tube and closed at one end thereof by an apprecia"e contact between the walls of the tube, and means for displaying the forms, and in various other details and features as will appear from a consideration of the following description taken in connection with the drawings which form a part thereof and in which Fig. 1 is a plan view of a mold by such a Aform embodying this invention 'may be made, such mold being shown open with a tube from which the hosiery form is to be made resting therein;

The mold 20 here shown for the purpose of illustration comprises two sections 2| and 22 hingedly joined at 23. Each section includes a depression 24 having such contour that when the GII 1933, v Serial No. 658,960

mold is closed the depressions coact to form a chamber 25 having walls which define lthe contour of the nished form. Each depression 24 is, as shown in Fig. 1, angular and is closed at one end by a block 26 suitably secured by bolts, screws, 5 rivets or the like to the portion of the section containing the depression. Each block 26 is provided with a depression 21 which forms a continuation of the depression 24, a recess 28 leading from the depressions 24 and 21 and a trough 30 10 from the recess 28 through the exterior of the block. It will be understood that the depressions 21, recesses 28 and troughs 30 are so located that, when the mold is closed, they will coact like the depressions 24 to form chambers.

At the other end of the depression 24 is formed in the section wall a recess 3| extending from the depression to the exterior of the section. A tongue 32 projects into the depression from .one side of the recess 3| and a tongue 33 projects 20 from a corresponding portion of the wall of the section 22 into its depression. T'he tongues 32 and 33 may be integral with the walls or may be formed from separate plates secured tothe walls. Projections 34 extend from the sections 2| and 25 22, certain of which are joined by hinges 35 and the sections, when swung on the hinges, close the mold. Suitable means may be provided to secure the sections in the mold-closing position, such, for example, as that shown in Fig. 3 in which are 30 shown projections 34 from the other sides of the sections held in contact by a clamping lever 36. The lever 36 is swung between plates 31 pivoted upon a pin 38 having offset portions rotatable in an integral tongue 39 on one of the projections. 35 Obviously by rotating the pin 38 the clamping action is regulated.

VThe hosiery forms are made from tubes 40 of Celluloid which being suitably treated are expanded in the mold as will be set forth below. 40 One end of the -tube 40 is slipped over a sleeve 4| supported upon a pipe 42 and is secured in place by a ring 43 which clamps the end of the tube in place. Attached to the end of the pipe 42 is a iiexible hose 44. Connected to the pipe 42 are 45 valve controlled pipes 45 and 46 from which steam, water and air is supplied to the pipe 42. In the illustrated mold steam is introduced through the pipe 45 controlled by the valve 41 and water, and air either separately or together are introduced 50 through the pipe 46 controlled by the valve 48. The form, arrangement and location of the pipes 42, 45 and 46 shown in Fig. 1 are, it will be understood, empirical and maybe varied asl desired.

One method of making a hosiery form embodyinto the atmosphere.

ing4 this invention is as follows. A tube 40 is previously soaked in water to render it manipulatable. 'I'he hose 44 and pipe 42 are introduced into one end of the tube and the end of the tube slipped over sleeve 4| and clamped thereon by the ring 43. The tube is then bent to conform roughly to the outline of the mold and laid in the depression 24 of the section 2| with one end extending through the recess 3| and the other end extending into the recess 28, the ring 43 and sleeve 4| resting inthe recess 28 and the pipe 42 resting in the trough 30, all as shown in Fig. 1. The mold is then closed and the sections fastened together by the clamping levers 36 or other fastening means. The end of the tube'40 in the recess 3| is pressed down by the closing of the mold to close the. tube. Enough steam is introduced into the tube to soften the walls thereof and then the section fastening means are tightened for the purpose of bringing the wallsof the sections into closer contact and of insuring the closure of the tube at the end clamped in the recess 3|. The mold is then heated preferably by plunging it into a bath of hot water and steam and the supply of steam into the tube in the mold resumed until the walls of the tube have been forced into contact with the walls of the depressions; ordinarily about three minutes. The supply of steam is cut olf and air with or without water is introduced to prevent any collapse of the formed tube, to clear the steam out of the tube and cool the walls of the tube. At the same time the mold is removed from the bath and cooled, preferably by spraying water upon it. y

The hose 44 conducts the steam past the angular portion of the tube and prevents it from striking directly uponthat wall of the tube as it would if the hose were omitted. This is desirable because the expansion of the tube at this portion is the greatest and if the steam were to strike it directly this wall would be unduly 'softened While the tube has been firmly clamped about the sleeve 4| there is nevertheless suiiicientl space left through which the introduced steam, air and water can escape under pressure into the recess and thence Since the tube expands laterally particularly at the angular portion which forms the knee of the form there is a tendency Yfor the tube to contract longitudinally which is permitted in the illustrated embodiment by the recess 28 in which the pipe, ring and sleeve mayI travel inwardly. The closed end of the formed tube, as shown in Figs. 45 and 5 includes the flanges and 5| which contact over an appreciable surface and are separated from the adjacent portions of the tube by depressions 52 and 53 formed by the tongues 3,2 and 33.

After the mold has been opened`the formed tube is removed and separated from the pipe 42. 'I'he portionv 54 of the formed tube `projecting from the foot is cut off, the anges 50 and 5| are cemented together and the depressions 52 and 53 nlled with any suitable .material (see Fig. 5). The upper end of the formed tube is also trimmed as desired and a thimble 55 left through which one or more holes 56 may be made to facilitate the supporting of the form upon a standard. The form is then finally cleaned and painted.

From the above it will be apparent that the hosiery formembodying this invention is constructed from a single tube closed at the foot end at the center of the sole. Such joinder is formed by two flanges secured face to face'and spaced from other portions of the sole by depressions filled with wood putty or other suitable material.

This line of joinder is obviously not conspicuous and in fact is concealed when the form is in use for displaying hose slipped upon it. Hosiery forms of similar flexible material have heretofore been made from an open ended tube which constiltutes the leg portion and a separately produced such suspending means comprises an upright post 60 secured at its foot to a base 6|. The post as shown in Figs. 7 and 8 comprises a bottom section 62, an intermediate section 63 and a top section 64 the diameters of such sections decreasingfrom the bottom to the top sections. A shelf 65 is carried by the 4section 62 and a washer 66 is mounted upon the top of the section 63. The section 64 which may terminate in a shelf 61 is passed through opposite holes in the thimble 55 which rests lon the washer 66. The standard shown in Fig. 10 comprises a post 1|) surrounded by a sleeve 1| to which is secured a projecting block 12. The block surrounds the post 'l0 so that sleeve 1| may be raised or lowered. Suitable fastening means, as for example, the set screw 13 are provided to secure the sleeve in any desired position. A shelf 14 may be mounted upon the top of the post as shown. 'I'he post may be screws 86 and 81x nx the rods in the blocks and the blocks on the post. The forms may be adjusted relatively to each other on the post and moved into any position desired so `that the forms will attract attention. Thus in Fig. 13 the forms are crossed in front of a wall 88 which conceals the post andithe major portion of the supporting mechanism. f
