Filed Feb. 12, 1957, Ser. No. 639,686 7 Claims. (Cl. 53-26) tion Serial No. 621,335, filed by John C. Berry on November 9, 1956, as well as the two board type exemplified by US. Patent No. 2,748,930, issued to J. A. Power on June 5, 1956. In the stocking packages of the one board type shown in the above noted Berry patents, a wide variety of stocking packages are disclosed and claimed in which either two stockings are placed in enveloping relationship over a single cardboard insert in a flat, slightly tensioned relationship, or one stocking is placed flat against one face of a cardboard insert and a second stocking envelopes the insert and the stocking in a fiat, tensioned relationship. In both procedures, a neat, compact, and extremely attractive stocking package is producedwhich has virtually revolutionized the marketing of stockings and has received widespread commercial acceptance by virtually the entire hosiery industry. In the two board type of package, two cardboards are provided with each carrying a single stocking in enveloping .i'elationsh'ip. The cardboards are secured to one another to complete the formation of the stocking pack- Several types of packaging machines have been employed heretofore in producing these types of stocking packages. However, such machines have possessed one or more disadvantages which have been found undesirable. Certain 'of the machines have been cumbersome and complicated, and expensive in initial cost. Others have possessed no versatility and have been limited in use to a single type of package.

I It is therefore a principal object of the present invention to provide a new and novel packaging machine for producing all types of stocking packages.

Another object of the present invention is the provision of an extremely simple packaging machine having virtually no moving parts.

Yet another object of the present invention is the provision of a packaging machine that is extremely low in initial cost .and requires no maintenance whatsoever.

'Still another object of the present invention is the provision of a packaging machine that possesses universal utility with. all forms of stocking packages in which one or m'orestockings is placed ona cardboard insert.

.A further object of the present invention is the provision of a new and novel method of packaging stockings. .A still further object of the present invention is the provision of a packaging-machine that will enable an operator to obtain a greater production rate.

Other and additional objects will become manifest from theensuing description taken in conjunction with the accompanyin'g drawings. y I

' .Broadly stated, the packaging machine of the present ice lying in a horizontal plane secured at one end to said base means, and second frame means lying in a horizontal plane secured to said base means, said first and second frame means being in superposed relationship with respect to one another.

To the accomplishment of the foregoing and related ends, the present invention then consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth in detail certain means in the carrying out of the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be employed.

The present invention is illustrated by way of example in the accompanying drawings, in which:

Fig. 11 is a cross-sectional view similar to that shown in Fig. 10 with a cardboard insert present therein.

Fig. 12 is a cross-sectional view similar to that of Fig. 11 in which one frame means has been withdrawn forming the stocking package, which is now ready for withdrawal from the machine.

Referring now to the drawings, and with particular reference to Figs. 1-3, an illustrative embodiment of a stocking packaging machine made in accordance with a variety of means other than that illustrated. Similarly,

invention compriseslbasemeans, firsLfixedfra'mqmeans 7 it may be necessary, in certain instances, to have the base member positioned above the work table or the like. This maybe accomplished by providing an intermediate stand which may be secured at one end. to the under surface of the base member 11, with the opposite end being secured to the fastening or securing means.

A thin, oblong board or frame member 13 is secured at one end by machine screws 14 or the like to a slightly recessed portion of the top of the base member 11, and

extends outwardly therefrom in a horizontal plane Theboard member 13 is preferably made from fine machined, light gauge aluminum to provide a strong, smooth surface over which a stocking may be pulled in a stretched, tensioned, and' enveloping relationship rapidly and without harmitoithe stoqkingl il'hewidthpt the. boardmem:

. e 3 ber 13 is such that it will be somewhat wider than the greatest width of any part of the cardboard insert used in the stocking package, and will correspondingly place any k g: pulle hereon; in a' n'et lled, nsio d state. The. length-ofthe. board member 13; is greater than the length of the: cardboard insert to be; used in forming any. stocking package; regardless of whetherthe stocking employed is of the stretched nylon type, combination yarn type, cotton type, or wool type, in order to provide the. machine. operator with proper working space to pull the stockings over the board member 13, and to place the cardboard insert therein. in a manner to be more fully described hereinafter. It should be noted that the board member 13 may be made by reversely bending a metal rod or the like in the same manner as the second frame member hereinafter described.

A second frame member 15' is. provided which is secured at one end to the. base member 11 and extends outwardly therefrom in a horizontal plane and in a superposed relation with respect to the cardboard member 13. As shown, the frame member 15 lies in a plane parallel to but slightly spaced from the plane of the board member 13. This arrangement is preferred, since it readily enables an operator to stretch a stocking over the board member 13 without hindrance from the frame member 15. Secondly, with certain types. of stocking packages, it is desirable to have the outer stocking in spaced relationship with respect to the inner stocking. It is to be understood, however, thafthe board member 13 and the frame member 15 need not be offset with respect to one another, although this arrangement is preferred. The frame member 15 is preferably in the form of an elongated metal -rod bent upon itself and possesses an elongated configuration in substantial conformity to, but slightly larger than that of, the configuration of the board member 13. The width ofthe frame member 15 is slightly greater than the width of the board member 13 such that when a stocking is placed thereon in a stretched condition, the stocking on one side will be slightly spaced from a stocking carried by the board member 13 in enveloping relationship. The frame member 15 may be made from any metal tubing or rods, such as, for example, aluminum. The metal should be finely machined to a high, smooth finish to prevent damage to the stockings when pulled thereover,

The opposite ends of the reversely bent frame member 15 are received and slidable within spaced openings 16 extending completely through the base member 11 to enable the frame member 15 to be moved back and forth in a horizontal plane, in a manner to be more fully dcscribed'hereinafter. The oppositefree ends of the frame member 15 are united to one another by a cross rod 17 which will; function 'asa handle means to push the'f'rame member 15 back and forth. A spring catch 18 is secured to the under surface of the base member 11 and extends rearwardly therefrom to receive and retain the cross rod or handle 17, thereby holding it in a locked position, as shown in Fig. 2. The length of the spring catch 18- must be such, that when the handle 17 is received therein, the opposite end of the frame member 15 will extend just forward of the free end of the board member 13.,

To limit the forward movement of the frame member 15, each arm thereof is provided with a stop collar 19, which ispositi-oned just forward of thehandle means *17 for a distance such that when the handle 17 is locked in the spring catch 18, the stop collars 19 will abut the base member 11. To limit the rearward travel of the frame member 15, a stop member 19a in the form of a rigid,

metal finger, rod, or strip is secured to the base member if. and extends forwardly therefrom and in'the same plane as thefrarnenie'mber'lS. Thelength ofthestop member 19:: will besuch as to abut the forward end of the frame meniber 15, as shown inqFig. 2; in broken lines,

when it is pulled rearwardly and clear of the stocking enveloping same. This particular arrangement just described will enable the frame member 15 to be locked insuperposed relation with respect to the board member 13 to permit the stockings to be placed thereon in a manner more fully describedlrereinafter, and yet will ea y per he. frame member .5 o b with rawal when necessary, to complete the formation of the de-- sired stocking package. However, the arrangement just described is solely for illustrative purposes, since there are other means readily available which will permit the locking of the frame member 15 in the desired position.

Reference is now to be had to Figs. 4 and 5 wherein a modified form of stocking packaging machine, generally designated by reference numeral 20, is shown in which automatic means are provided to insert the cardboard insert into or between the stockings. The stocking packaging machine 20 is provided with a base 21 and a O- clamp 22 of the same general design in the corresponding parts shown in the form of the invention of Figs. l-3.. A thin, oblong board or frame member 23 is secured at one end to the, top of they base member 21 in the same, manner as the board member 13 of the first form of the invention shown in Figs. 1-3. In the modified form of the invention, the board member 23 will possess the same width as the board member 13, but its length will be. considerably less since the need for the working space. is eliminated.

A second frame member 24 is secured to the base member 11 and extends outwardly therefrom in the same general relationship as the frame member-15 of the first form. of the invention hereinbefore described. Each side arm of the frame member 24- extends through openings in the base memberZl and is slidable with respect thereto. The side arms of the frame member 24 extend well beyond and rearwardly of the base member 21, and are connected to one another by a cross bar or handle means 25.

A cardboard insert receptacle 26 is positioned between the side arms of the frame member 24 and rearwardly. of the base member 21 and functions as a hopper'means' for a plurality of cardboard inserts carried therein in stacked relationship. The bottom of the receptacle 26 is provided with spring means 27 which support a free floating bottom plate which will continuously urge the cardboard inserts. carried in the receptacle '26 upwardly. The rear end face of the receptacle 26 is provided with a rearwardly extending spring catch 29 to receive and retain the cross rod orhandle 25, thereby holding it in a locked position, as shown in Fig.5. The dimensions of the spring catch 29.: will be substantially identical with. the spring catch 18 of the first formof the invention hereinbefo're described. Each side: arm of the frame member 24 is providedwith a stop collar 30, which is positioned well forward of the handle means 25 for a distance such, that whenthehandle 25 is locked in the spring catch 29, the stop collars 30 will abut the base member 21.

A transfer mechanism generally designated by reference numeral 31 is provided in association with a receptacle 26 to automatically insert a cardboard form into or betweenthe stocking to complete; the formation of. the stocking package. The transfer mechanism comprises a Vertical support 32'. with. the upper free end thereof supporting a power drivend'riving wheel or cam 33 in journaled relationship. A first link arm 34 is secured at one end to thedriving wheel 33 in offset relationship withrespect; tothe center point thereof: Stop means 35-are positioned on the wheel 31 in close proximity: to and in cooperative relationship to the first link arm 34 to insure the back, and forth motion of'the first link arm-34 during the rotation of the driving Wheel 43. A V or L-shaped second link arm: 36 is secured at one end to the free end of the first link arm-34s The-second link arm 36is so constructed that upon rotation of the driving wheel 33, it willnpassfrom oneendto theotheri of the receptacle 26 to enable a cardboard insert to be pushed forward into or between the stockings carried by the board member 23 and the frame member 24. The free end of the second link arm 36is provided with finger means to facilitate the forward transfer of the cardboard insertfrom the receptacle 26 to board member 23.

Reference is now to be had to Figs. 6-12 wherein diagrammatic perspective views are shown to illustrate the operation of the stocking packaging machine shown in Figs. 1-3 in forming a stocking package. In Fig. 6, the stocking packaging machine is shown with the board member 13 and the frame member in locked operating position and ready to receive the stockings to be packaged. To form the stocking package, a-first stocking A is pulled over the board member 13 in stretched and tensioned enveloping relationship therewith, as shown in Figs. 7 and 8. A second stocking B is then pulled over the frame member 15 in a tensioned, stretched, enveloping relationship, with the cuff portion of the outer stocking B being placed in substantial alignment with the cuff portion of the first stocking A. This operation results, as shown in Fig. 10, in the outer or second stocking B being in enveloping engagement with the top face of the inner or first stocking A, and the remaining portion of the outer stocking B being spaced from but enveloping the remaining portion of the first or inner stocking A. This operation provides a spaced area between the stockings within which the cardboard may be inserted between the first stocking A and the second stocking B, as indicated in Fig. 9 and clearly shown in Fig. 11. To complete the formation of the stocking package, the frame member 15 is pulled rearwardly, causing the second stocking B to snugly snap into enveloping relationship with the first stocking A and the insert C. The stockings A and B and the cardboard insert C are then pulled off the board member 13, folded, if desired, and riders or bands or the like applied, thereby producing a stocking package which conforms to that stocking package disclosed and claimed in US. application Serial No. 621,335, filed by John C. Berry on November 9, 1956. The method for forming this particular stocking package likewise constitutes a part of the invention, disclosed and-claimed in the aforementioned Berry application.

To form a stocking package in conformity with the stocking packages disclosed and claimed in the Berry Patents Nos. 2,696,295 and 2,742,149 hereinbefore identified, the first stocking A is pulled over the board member 13 and the second stocking B is pulled over the frame member 15 in the same manner shown in Figs. 7-l0. The cardboard C is then inserted between the board member 13 and the first stocking A. The frame member is then pulled rearwardly, resulting in the first stocking A enveloping the cardboard member C on the frame member 15, with the second stocking B enveloping the first stocking A, as shown in Fig. 12. Alternatively, with this type of package, the frame member 15 may be withdrawn prior to inserting the cardboard insert C, resulting in the outer stocking B enveloping the first stocking A. The insert C is then placed between the board member 15 and the first stocking A. With this form of package, it is not essential, as hereinbefore indicated, that the board member 13 and the frame member 15 be in offset relationship with respect to one another, although for ease of operation and maintenance of production, offsetting in general is preferred.

To form the so-called one-on-one or two board type of stocking package exemplified by US. Patent No. 2,742,149, the first stocking A is pulled over the board member 13 in the manner hereinbefore described. The stocking B is then pulled over the outer frame member 15. A cardboard insert is placed between the first stocking A and the second stocking B, and the two are then pulled forwardly off of the frame member 15 to form one-half of the stocking package. A second cardboard insert is then placed between the board member 13 and thefirst stocking A and fitted therein. The first stocking A and the cardboard insert are pulled off of the board member 13 to constitute the second half of the stocking package. In this operation, it is noted that the frame member 15 is not withdrawn rearwardly but remains in locked position throughout the formation of the stocking package. An alternative method that may be employed in forming the two board type of packaged stockings is to withdraw the frame member 15 rearwardly before making the package. One stocking is then pulled over the boardmember 13 and the cardboard inserted therein, and the cardboard with the enveloping stocking is pulled off the board member 13. The operation is repeated and the resulting two stockings, each enveloping a cardboard insert, are then secured to one another to complete the formation of the stocking package.

The present machine is of particular utility in forming cuffed anklets of the type worn by children in which the cuff is turned upon itself when the stocking is worn. To package this type of stocking, a stocking is pulled over the board member 13 and a second stocking pulled over the frame member 15. The frame member 15 is then withdrawn rearwardly. The cuffs of the stocking are then reversely folded upon themselves with the cuff of the first or inner stocking folded over the cuff of the outer or second stocking. The cardboard insert is next placed between the board member 13 and the first stocking and the insert with the two stockings are then withdrawn from the board member 13. The formed stocking package is then folded upon itself and the toe portion of the package is then tucked in between the folded cuff portions of the stockings to hold the stocking package in a folded state. An alternative method in forming a cuffed package may be employed in which the cuffs will not be folded prior to inserting the cardboard.

Rather, the two stockings are pulled over the two

frame members

13 and 15 as in the usual manner. The card board insert is then inserted with the end of the insert being positioned well within the stockings, i.e., about half-way beyond the free end of the cuff portions. The cufis may then be folded upon themselves with theresulting fold line being in substantial alignment with the top edge of the insert. The stockings and insert are then withdrawn and folded in the manner hereinbeforedescribed to complete the formation of the stocking package.

In the operation of the form of packaging machine shown in Figs. 4 and 5, the stockings will be pulled over the

frame members

23 and 24 in the manner hereinbefore described. The operator then actuates the driving wheel 33 to cause the link arm 36 to push the cardboard insert forward from the receptacle 26 into or between the stockings. After the insert is positioned, the stockings and insert are pulled off and the desired package then formed.

While, as hereinbefore indicated in the description of the operation of the packaging machine, the frame member is pulled rearwardly to insure a proper enveloping of one stocking with respect to the other, it

-is to be noted, however, that it is possible to operate the present packaging machine in forming certain stocking packages without rearwardly withdrawing the frame member 15. However, in general, greater production is achieved and a much neater package is obtained by having the frame member 15 withdrawn from the outer stocking to enable the same to snap into snug engagement with the inner stocking.

While there have been described herein what are at present considered preferred embodiments of the invention, it willbe obvious to those skilled in the art that modifications and changes may be made therein without departing from the essence of the invention. It is therefore to be understood that the exemplary embodiments are illustrative and not restrictive of the invention, the scope of which is defined in the appended claims, and
