\NVENToRs ATTORNEYS United States Patent HOSIERY FORM INSERTING APPARATUS AND METHOD Wade V. Bowman and Frank H. Houck, Hickory, N. (3.;

said Frank H. Honck assignor to said Wade V. Bowman This invention relates to the art of pairing hosiery, and, more especially, to an improved method of and apparatus for placing or mounting pairs of hose, such as mens hose, on rigid or flexible inserts or forms made from paper, cardboard, plastic or the like, preparatory to passing the pairs of hose through subsequent processes and/ or maintaining the hose in an elongated, flat state for display purposes.

It is becoming increasingly popular in the displaying of mens hose, particularly those of the so-called stretch type, to mount the two of each pair of hose on a common form or insert so as to not only provide a neat appearance to the display, but to also maintain the originally intended shape of the hose from the time they are manufactured until they are put into use.

Heretofore, the placing of pairs of hose on individual forms has been performed manually and has necessarily been relatively difficult and time-consuming. One of the most outstanding difficulties encountered in the placing of hose on individual forms has been involved in the placing of a second of a pair of hose on a form on which the first hose has been positioned, due to the frictional resistance to relative movement between the hose as the second hose was drawn over the first hose. instances, this has caused undue stretching of the second hose and has frequently resulted in imperfections in the hose caused by excessive handling of the hose during this process.

It is therefore an object of this invention to provide a simple and eflicient means for and method of positioning pairs of hose or socks on individual forms or inserts which includes the positioning of an insert between a first pair of correspondingly formed blades or guides, then drawing the first hose of a pair over the blades with the insert therebetween and, thereafter, positioning a second pair of blades astride the sock or hose posi- In some tioned on the first pair of blades, then drawing a second sock or hose over the second pair of blades with the first sock, the first pair of blades and the insert therebetween and then withdrawing the blades or guides from the two socks or hose leaving the insert disposed within the first hose in said pair.

It is another object of this invention to provide an apparatus of the character described including a nest which is preferably stationary, provided with means for receiving and supporting one end of an insert and wherein ing ends of the first and second pairs of form guides or blades. When the insert is positioned in the nest, the toe ends of the inner and outer or first and second pairs of blades or guides are positioned adjacent the weltmovable means are provided for supporting correspondsupporting portion or end of the insert and means are provided for imparting movement to the blades relative 2,857,085 Patented 'Oct. 21, 1958 be inserted over the first pair of blades and the insert.

Thereafter, the second pair of blades, which are springbiased, are released to permit the same to move to a position astride the sock or hose positioned on the first pair of blades, whereupon a second sock or hose of said pair is drawn over the second pair of blades, thefirst hose or sock, the second pair of blades and the insert, simultaneously. Thereafter, movement is again imparted to the first and second pair of blades to withdraw the same from the corresponding hose or socks whereby the pair of hose on the form or insert may be removed from the nest.

Referring more specifically to the drawings, the numerals it? each broadly designate a base, platform or table. (Figure 1) for each of the improved form inserting devices in Figure l. The tables, platforms or bases 10'are parts of a suitable conveyor mechanism 11 with which the improved form insertingapparatus is preferably used and which includes a moving belt 12, onto which each successive pair of hose, with "the inserts therein, maybe placed by operators adjacent each of the tables, plat forms or bases 10. The conveyor mechanism 11 is shown diflferent means which, may be used in association with the improved hosiery form inserting devices and, since all of the hosiery form inserting devices are identical, only one of them will be described.

As heretofore stated, the improved apparatus is used for inserting a rigid, semi-rigid or fiexibleform, broadly designated at 13, within a pair of hose, the form 13 being shown in solid lines in Figure 2 and in broken or phantom lines in Figures 3 and 7. The first or inner hose of each pair is generally designated at 14 and the second or outer hose of each pair is generally designated at 15. The hose, socks or stockings shown in Figures 1, 3, 4 and 5 are shown in the form of mens half hose and, while they may be knit from any desired material, forms such as form 13, are usually inserted in hose made from so-called stretch yarns or lively yarns in order to maintain the hose in proper flat shape for subsequent processing and/or displaying of the hose.

The form or insert 13 shown in Figures 3 and 7 is shaped to conform to the usual hose in that it includes an elongated body B which is relatively thin, say, onesixteenth of an inch thick, and which body B is provided with a rounded toe portion T at one end thereof, a flatended, relatively narrow or reduced welt portion W at its other end and a rounded projection or heel portion H on a medial portion of the body B. Of course, the body B and its toe portion T, heel portion H and welt portion W conform substantially to the ,usual body, toe, heel and welt portions of the hose 14, 15.

The improved hosiery insert inserting apparatus is shown in vertical or upright position in the drawings and the various parts thereof will be hereinafter described as to their relationship with respect to vertical and horizontal planes as shown in the drawings, for purposes of orientation. However, it is to be understood that the attitude of the improved apparatus may be varied and that the improved apparatus may even be inverted when it is used without departing from the spirit of the invention.

The improved insert form inserting apparatus comprises an elongated relatively thin nest baror insert support 20 which extends longitudinally of and immediately above an elongated opening 21 formed in the base or platform and which opening 21 also extends through a substantially rectangular auxiliary base or cylinder-supporting bracket 22 suitably secured vto the lower surface of the main base 10. Opposite ends of the nest bar or hosiery form support preferably are turned downwardly or have downwardly projecting portions thereon which tightly fit in suitable notches provided in the main base 10 adjacent opposite end walls of the slot 21.

A medial portion of the bar or hosiery form support 20 has the lower portions of a pair of upwardly and inwardly bent leaf spring clamping members 23, 2t suitably secured to opposite sides thereof Whose upper portions are preferably rounded and flared outwardly in order to facilitate ready insertion of the welt end of a form 13 therebetween. The flat lower edge of the welt portion W of the hosiery insert or form 13 then rests against the upper edge of the nest bar 20 and is thereby maintained in substantially perpendicular relation to the nest bar 20.

Mounted for vertical movement relative to the nest bar 20 and the clamping members 23, 24 is a first or inner pair of closely spaced relatively thin and rigid inserts or form guides or blades 26, 26' which also straddle the nest bar or hosiery form support 20. The major portion of the length of each form guide 26, 26' is of substantially greater width than the leaf spring clamping members 23, 24. In orderto accommodate the leaf spring clamping members 23, 24, each of the first or inner form guides 26, 26' is provided with an elongated slot 30 therein of slightly greater Width than the corresponding leaf spring clamping member. Vertically movable with the first or inner insert guides 26, 26' is a pair of pivoted or outwardly movable second or outer, elongated and relatively thin insert guides 31, 31 which normally closely straddle the first or inner insert guides 26, 26.

The inner or outer insert guides 26, 26 and 31, 31' are all of substantially the same shape and size throughout the major portion of the lengths thereof and are shaped to conform substantially to and are preferably slightly larger than the insert or form 13, to the extent that each of the insert guides has a rounded free end or toe portion 32 and a medial outwardly projecting heel portion 33 thereon which conforms substantially to the toe portion T and the heel portion H of the hosiery insert of form 13.

As best shown in Figures 7, 8, ll, 12, 13 and 14, the lower proximal surfaces of the inner form guides 26, 26 are suitably secured to opposite sides of a relatively thin upwardly projecting portion 35' of a guide block,

I form guide carriage broadly designated at 36 which is shown in Figures 12 and 13 as being substantially U-shaped in plan. The portion 35 is formed integral with or suitably secured to a leg 37 of the carriage 36 and the other leg of the carriage 36, indicated at 40, is guided for vertical sliding movement on a pair of guide rods 41, 42 disposed astride a vertically disposed cylinder 43.

it will be noted that the leg 4th of the carriage 36 (Figures 12 and 13) is provided with an opening 44 therein through which the cylinder 43 loosely extends. The upper ends of the cylinder 43 and the guide rods 41, 42 are suitably secured to the auxiliary base or bracket 22 closely adjacent the rear wall of the opening 21. In this instance, the upper end of the cylinder 43 is pressed into or otherwise secured in a cavity 45 formed in the lower surface of the bracket 22 (Figure 11) and the bracket 22 has a passageway 46 therein which communicates with the interior of the upper end portion of the cylinder 43. One end of a fluid pressure conduit 47 is connected to the bracket 22 for communication with the passageway 46 to thereby introduce fluid pressure, such as hydraulic fluid or compressed air, into the upper end of the cylinder 43 or to permit escapement of the fluid pressure from cylinder 43, as desired.

A piston 50, mounted for longitudinal or vertical slidin movement in the cylinder 43, has one end of a piston rod 51 connected thereto which penetrates a cylinder closure or head 52 fixed on the lower end of cylinder 43. The lower portion of cylinder 43 has a guide bracket 53 fixed thereon which is shown in Figures 9 and 10 as being substantially T-shaped in plan and to which the lower ends of the guide rods 41, 42 are secured. The lower portion of cylinder 43 has one end of a pipe or conduit 54 communicatively connected thereto (Figures 6, 8 and 11).

The free lower end of the piston rod 51 slidably or loosely penetrates a cult member or arm 56 which is adjustably secured on piston rod 51 by means of a pair of lock nuts 57. The bar or cult member 56 is also loosely penetrated by the lower portion of a plunger or guide rod 6.0 which is adjustably secured in the bar or cuff member 56 by means of a pair of lock nuts 61. The guide rod 60 is guided for longitudinal movement in the T-shaped bracket 53 and its upper end is fixed to the leg 37 of the substantially U-shaped blade carriage 36. It is thus seen that introduction of fluid pressure alternately into opposite ends of the cylinder 43 will cause corresponding upward and downward movements to be imparted to the guide carriage 36 and the inner or first pair of blades or form guides 26, 26.

Now, it will be observed in Figures 7, 11 and 14 that the lower ends of the second or outer form guides 31, 31

assaoss' .5 the lower portions of the extensions 63, 63 are, preferably fixed on opposite end portions of a stud or shoulder bolt 65, as by a key 66 (Figure 15). The outer blade or form guide extensions 63, 63 engage opposite ends of a bushing 67 which is also keyed to the stud or shoulder bolt 65 by the key 66. The bushing 67 is oscillatably mounted in the lower end of the arm 64 depending from the leg 37 of carriage 36.

The outer or second blades or form guides 31, 31 are normally urged to a position in parallel coinciding relationship with the inner blades or form guides 26, 26' by any suitable means such as a tension spring 70, one end of which is connected to a spring anchor 71 projecting outwardly from the extension 63 of the blade 31 and the other end of which is connected to a spring anchor 72 suitably secured to and projecting outwardly from the leg 37 of carriage 36. The spring anchor 72 also serves as a stop or limiting means, since the spring 70 urges the right-hand edge of the extension 63 in Figures 2, 3, 4, and 7 into engagement with the spring anchor 72 and the spring anchor or stop 72 is so positioned that the blades 31, 31 are then in parallel coinciding relationship with the inner or first blades 26, 26 as shown in Figures 2, 4, 5, l2 and 14.

An arm 74 extends laterally from a medial portion of extension 63 of blade 31 and has a pivoted dog or latch 75 mounted thereon, as at 76. The pivoted latch or dog 75 is overbalanced, or may be suitably spring urged, so that it normally extends in substantial alinement with the arm 74, its movement in a counterclockwise direction in Figures 2, 3, 4, 5 and 7 being limited by a projection 77 Y on the latch 75 engaging the lower surface of the arm 74.

The latch 75 is disposed in the vertical plane of a manuallyreleasable outer blade tilting means shown in the form of a detent, pin or shaft 80 mounted for substantially horizontal sliding movement in legs a, b of a substantially h-shaped bracket 81 suitably secured to and depending from the auxiliary base plate 22 (Figures 8, 12 and 13).

It will be noted that the pin or detent 80 is encircled by a compression spring 82, one end, of which engages the leg a and the other end of which engages an enlarged portion or collar 83 fixed on the pin or detent 80 and which collar 83 is normally urged against the inner surface of the leg b. The end of the detent or pin 80 remote from the vertical plane of the latch 75 has a suitable handle or knob 84 thereon for manipulation by an operator. It will be noted that the position of the detent or pin 80 relative to the base and the length of the slot 21 in the base 10 is such that the blades 31, 31'

are swung outwardly clear of the portions of the blades 26, 26' which straddle the insert 13 when the blades 26, 26 are in fully raised or operative position.

Any desired means may be provided for imparting longitudinal movement to the plunger or guide rod and the ram embodied in the piston 51 and the double-acting cylinder 43 are merely shown as a preferred means for controlling movement of the rod or plunger 60. It will be observed in Figure 6 that the ends of the conduits 47, 54 are connected to a suitable four-way valve, shown schematically at 87 in Figure 6, provided with a movable or rotatable core 88 to which one end of a lever 89 is secured. The free end of lever 89 has a link 90 connected thereto whose other end is connected to a treadle bar or pedal 91 pivotally mounted, as at 92,.on the floor orsurface S which supports the platform or base 10. It is apparent that suitable legs, not shown, would be provided for supporting the base. 10 in spaced relationship above the surface S.

The pedal 91 is normally urged upwardly by a compression. spring 93 and it will be noted that the valve 87 has a fluid pressure inlet conduit or pipe 94 connected thereto which extends to a suitable source pf fluid pressure indicated at 95. The valve core 88 has passageways b, c therein. When the pedal 91 is in raised position, passageway -c establishes communication between the pipe or conduit 94 and the conduit 54 and the passageway bthen establishes communication between the pipe or conduit 47 and a return or discharge conduit or pipe 96. Thus, with the valve core 88 in the position shown in Figure 6, fluid pressure is introduced to the lower end of the cylinder 43 as it is exhausted from the upper end thereof so the blades 26, 26, 31, 31 occupy raised position such as that shown in Figures 3, 4, 7, 8, 11 and 14.

Of course, when pedal 91 (Figure 6) is moved downwardly, to move the lever 89 to the broken line position, the direction of flow of fluid pressure is reversed and this imparts downward movement to the blades or form guides 26, 26, 31, 31. This downward movement is limited by a pair of adjustable limiting members shown in the form of nuts 97 mounted on the guide rods 41, 42. The nuts 97 are then engaged by the lower surface of the leg 40 of the carriage 36.

In operation, the carriage 36 and the blades 26, 26, 31, 31 are lowered, by depressing pedal 91 in the manner heretofore described, so the carriage and blades occupy substantially the position shown in Figure 2. A hosiery form or insert 13 is then positioned upon the nest bar 20 and clamped between the leaf spring clamping members 23, 24, whereupon the pedal 91 is released to permit fluid pressure to enter the lower end of the cylinder 43 as it is exhausted from the upper end thereof. Thus, the piston 50 and the piston rod 51 move upwardly to impart corresponding movement to the guide rod or plunger 60 and the carriage or the bracket 36.

In the course of upward movement of the carriage 36, the latch engages the detent so that, with further upward movement, the outer blades 31, 31' are swung outwardly away from the inner blades 26, 26'. It will be noted that the inner pair of blades 26, 26 then move upwardly to occupy positions astride the hosiery form or insert 13 so an operator may then draw the first hose 14 of a pair over the pair of inner blades 26, 26' and the hosiery form or insert 13 as shown in, Figure 3.

The operator then pulls the pin or detent 80 out of engagement with the latch 75 so the spring 70 then swings the blades 31, 31' from the position shown in Figure 3 to that shown in Figure 4. The second hose 15 of said pair is then drawn downwardly over the blades 31, 31 and will, of course, be drawn about the previously positioned hose 14, the blades 26, 26' and the insert 13. It will be noted that, since the clamping members 23, 24 are disposed in the slots 30, they do not project outwardly beyond the inner blades or form guides 26, 26' and will not, therefore, interfere with the positioning of hose on the inner blades or form guides 26, 26'.

After the second hose 15 of said pair has been positioned over the outer or second pair of blades 31, 31, the pedal 91 is again depressed to impart downward movement to the carriage 36 and the blades 26, 26, 31, 31' to withdraw said blades from the corresponding hose 13, 14. The upper end wall of each slot 30 is preferably rounded to conform to the shape of the clamping members 23, 24. This permits the blades to be lowered to' Although the detent 80 may occupy operative position, that is, is disposed in the vertical plane of the latch 75, during downward movement of the carriage 36 and the blades, it is apparent that the latch 75 will merely swing upwardly as it engages the detent 80 and when it has passed the detent, the latch will then return to the substantially horizontal position shown in Figures 2 and 5. It will be noted that, as the toe-portions 32 of the blades 26, 26', 31, 31 move downwardly to substantially the position shown in Figure 5, the welts of the corresponding hose move inwardly to conform to the reduced welt portion of the hosiery insert 13.

A cycle in the operation of the improved hosiery form inserting apparatus is then completed'andit is merely, necessary for the operator to grasp the hose on the insert '1 and withdraw the insert from between the clamping members 23, 24 and place the same on the conveyor belt 12 for advancing them ,to a subsequent process such as heat-setting or packaging.

It is thus seen that I have provided a novel method and means which facilitates quick and easy insertion of inserts in pairs of hosiery and which practically eliminates any possibility of the hose being damaged during the course of the operation.
