18 Claims. (Cl. 223-76) The present invention relates to new and useful improvements in boarding machines commonly used in the processing of nylon and like hosiery. More particularly, the present invention relates to improvements in machines of the type described in the U. S. patent to Heliot, Number 2,492,285 dated December 27, 1949.

In boarding machines of the type to which this invention relates, the stocking forms are arranged in three successive groups on a rotary conveyor or turntable. Each group comprises a plurality of forms mounted in vertical planes and normally radiating from a vertical axis. The forms in each group are loaded with stockings and are arranged to be enclosed successively by a vertically movable cover for treatment by pressure steam, or the like. As the stockings in each group are being treated, the stockings previously treated are removed from the forms in that group and a fresh supply of untreated stockings is placed on the group of empty forms. To facilitate placement and removal of the stockings on the forms, each form in the group is pivotally mounted for horizontal movement about a vertical axis so that adjacent forms may be swung apart on their pivots to provide ample work space for the removal of the stockings from each form.

With the circular arrangement of the patented device, there is room for only one operator at a time to work at the forms in each group. Because of the time required, the operator must start stripping the stockings from the forms as soon as they are uncovered. Consequently, the welts of the stockings which are ordinarily quite moist from the steam treatment frequently do not have time to dry completely before they are removed from the forms, and the operation must, therefore, be delayed. In addition, valuable time is lost when the operator must separate each form from the remaining forms, and swing it into the desired work position, at the same time swinging the previously loaded form out of the way.

With the foregoing in mind, a primary object of the invention is to provide a novel construction and arrangement which affords greater speed in the removal and placement of stockings on the forms of a boarding machine.

A further object of the invention is to provide an arrangement of the forms in each group on the turntable which permits greater utilization of the space under the cover of the boarding machine.

More specifically, the invention contemplates a novel arrangement of stocking forms on the turntable of the boarding machine which enables two operators to work at the stocking forms of each group on the turntable.

Another object is to provide a novel mounting means for the stocking forms in each group which operates to automatically position the individual forms of the group in the most efiicient position for placement and removal of the stockings on the form.

These and other objects of the invention and the various features and details of the construction and operation thereof are more fully set forth hereinafter with reference to the accompanying drawings, in which:

Fig. 7 is a diagrammatic plan view of a modified arrangement of forms in accordance with the present invention;

Fig. 8 is a plan view of a modified form of a mounting for the forms, within the scope of the present invention; and,

Fig. 9 is a front elevational view of the mounting illustrated in Fig. 8.

The boarding machine illustrated in the drawings comprises a base 9 having uprights 10 and 11 which mount a cover 12 for axial movement in a vertical direction. Means is provided within the base to supply pressure steam under the cover when it is in the lower position shown in Fig. l. The cover 12 is adapted to enclose a group of vertically disposed stocking forms which support the hosiery for setting treatment by steam. To this end, in the present instance, a plurality of forms 20 are arranged in three groups 21 on a rotary conveyor or turntable 22, each group being mounted within an annular ring of the turntable. The turntable comprises three such rings and rotates about the upright 11, so that each group is moved successively under the cover and enclosed thereby for treatment by the steam. To provide compactness and a high degree of utilization of the space, the forms are mounted in spaced parallel alignment when the group is under the cover, but to provide for easy removal and replacement of the articles on the forms, the forms may be pivotally displaced from their paralel relation as is illustrated at location C in Figs.

Each stocking form 20 is mounted for pivotal movement about a vertical axis. The form is integrally secured to a horizontal arm 24 which, in the present instance, takes the form of a vertical base plate which projects laterally beyond the forward and rearward edges of the form as indicated at 25 and 26 respectively. The forward projection 25 is provided with an offset flange 27 having an upturned lip which is adapted to bear against the next adjacent base plate to constitute a spacer element for the forms (see Figs. 1 to 3 inclusive). The rearward projection 26, on the other hand, is stamped out and turned back upon itself as illustrated in Figs. 3 and 4 to form a bifurcated mounting for the vertically spaced axially aligned

pivot studs

28 and 29. The upper and lower bifurcations define between them a recess 32, and the turned back portion 30 is cut away from the recess 32 as indicated at 31 for a purpose set forth more fully hereinafter. The

studs

28 and 29 are pivotally mounted in vertically aligned

sockets

34 and 35 formed in a carrier defined by spaced

horizontal carrier plates

36 and 37 respectively.

In accordance with the invention, a cam element 40 is pivotally mounted on the stud 28 intermediate the carrier plate 36 and the upper bifurcation of the end plate 24. The cam 40 is formed as illustrated in Fig. 6 having a central aperture 41, rearwardly converging

cam surfaces

42 and 43, and forwardly projecting

lugs

44 and 45 which are spaced-apart, as illustarted, to define a recess 46. The aperture 41 receives the stud 28, and the cam is positioned on the stud so that the recess 46 engages The

lugs

44 and 45 extend forwardly whereby upon relative pivotal movement of the form 20 and the cam 40, the

lugs

44 and 45 engage against the right and left faces respectively of the rear portion 26 of the end plate 24. It should be noted that the turned back portion 30 is cut back sufficiently at 31 to escape engagement with the lug 45 and thereby afford greater relative pivotal movement of the form and the cam.

The

carrier plates

36 and 37 are rigidly joined to a carrier base 48 as indicated at 49. Each carrier base 48 is secured to and forms an integral part of the turntable 22. As pointed out above, three groups of forms are mounted on the turntable 22, each group occupying a single carrier base 48.

In the embodiment illustrated in Figs. 1 to 6 inclusive, each group 21 comprises two series of forms, 52 and 53 respectively (see Fig. 1). The

sockets

34 and 35 for each series are disposed in generally transverse horizontal alignment and the

sockets

34 and 35 of the two series converge forwardly and inwardly from the rearmost marginal portion of the carrier base 48 towards the central portion as illustrated in Fig. 2. The turntable 22 includes also a fiat annular member 54 concentrically disposed within each link of the turntable for sealing engagement with the cover 12. The member 54 underlies the two series in circumscribing relation thereto when the forms are in their normal spaced parallel position, as shown with reference to series 52 in Fig. 2, so that when the cover 12 is sealed against the member 54, the forms will be enclosed by it. Means is provided in the base 9, to seal the lower end of the bell and to introduce steam at predetermined pressure and temperature into the chamber, as shown in the previously mentioned patent.

In the operation of the device the turntable rotates clockwise to carry each group of forms into locations A, B, and C successively, as seen in Figs. 1 and 2. After a group 21 of loaded stocking forms has been treated by steam in location A, the cover 12 is elevated by mechanism Within the central upright 11. In this respect it is noted that the piping at the top of the cover is slidably engageable in a junction box adjacent thereto as clearly illustrated in Fig. 1. The turntable 22 is then rotated so as to shift the treated group 21 from location A to location B and to shift an untreated group from position C into location A for treatment by the steam. During this treatment, previously treated stockings which were dried in location B by the heat in the forms are removed from the forms 20 in groups 52 and 53 in location C and untreated stockings are placed on the empty forms.

When the stocking forms are moved from location A under the cover, the forms of both the series 52 and 53 are in the spaced parallel relation shown in connection with the series 52 in Fig. 2. After the articles have been allowed to dry at location B, they are removed from the forms at location C. To this end, the first form in each series is pivotally displaced outwardly from the spacedaligned relationship shown, so as to afford ample room for the removal and placement of the stockings. After an untreated stocking has been placed on the form, the latter is pivoted on the

studs

28 and 29 into engagement with an arm 57, described more fully hereinafter. The pivotal displacement of the form 20 causes the rear end portion 26 of the form to engage against the lug 44 of the cam 40 associated with the form, and the cam will be pivotally displaced with the form 20. Upon pivotal movement of the cam, the cam surface 43 engages against the cam surface 42 of the next adjacent cam. The forcible engagement of the two cam surfaces causes the latter cam to pivot counterclockwise about the stud 28 (see Fig.

Pivotal movement of this cam effects engagement of the lug 45 against the end portion 26 of its associated form 20 to thereby cause the latter to be pivotally displaced away from the succeeding forms in the series. Because of the limited lost motion between the cam and the form afforded by the inter-engagement of the

recesses

46 and 32, the form may be adjusted to assume the most desirable angular position for removal and placement of the stocking. After the untreated stocking is in place on the form, the form is pivoted counterclockwise to engage against the spacer element 27 of the preceding form. This pivotal movement through the action of the cams will displace the next succeeding form to an angular position intermediate its two adjacent forms. The treated stocking may then be removed from the form and an untreated article placed on the empty form.

By arranging the forms in two series, two operators are enabled to work on the forms in each group in location C, one operator Working on the forms in the series 52 and the other operator working on the forms in the series 53. To insure against outward pivotal displacement of the forms as they are carried by the turntable 22 to a position underlying the cover 12, an arm 57 is provided at each side of the group of forms 20. Each arm 57 is pivotally connected to the carrier base 48 at 56 and is biased to either the open position illustrated at 57a or the closed position illustrated in broken lines 57b of a spring 58. The spring is secured at one end 59 to the carrier base 48 and is secured at the other end 60 to the arm 57. The position of the attachment 60 is such that when the arm is in the position 57a, it will be resiliently held in that position against a stop 61 by the spring. Pivotal displacement of the arm 57 will move the spring 61 over the pivotal center 56 of the arm so that the spring 58 will bias the arm inwardly against the forms 20 as clearly illustrated at 57b in Fig. 2. Thus, when the forms have been stripped and loaded, the arms 57, 57 are snapped inwardly so as to close the forms to the spaced parallel position within the zone defined by the annular ring 54. After the stockings on the forms have been treated and dried and the group moved to location C, outward displacement of the first form in the series will snap the arm 57 outwardly to the position 5711.

It is desirable that the form be held reasonably stationary as the articles are removed and replaced. To this end, a brush element 63 is secured to the carrier base 48 so that its bristles extend upwardly into engagement with the lower edge of the forms 20. The bristles being relatively stiff, will impede pivotal movement of the form so as to hold it reasonably steady while the articles are being removed and replaced.

A modified form of the invention is illustrated in Fig. 7 wherein a plurality of vertical stocking forms 65 corresponding to the group 21 of the forms 20 in the pre viously described embodiment are pivotally mounted in a plurality of transversely aligned sockets 66 in a carrier 67. The carrier 67 is adapted to be mounted on a turntable (not shown) like the carrier defined by the

elements

36, 37, and 48 in the previously described embodiment. Interposed between the carrier 67 and each form 65 is a cam 68 identical in structure and function to the cam 40 of the previously described embodiment.

Arms

69, 69 are provided at the opposite sides of the group of forms 65 and function similarly to the arms 57, 57 of the first-described embodiment. In this modification of the invention, there is room for only one operator to handle the forms in each group but otherwise the device functions identically with the previously described embodiment, so that the forms are automatically pivoted into the proper position for stripping and loading.

A further embodiment is illustrated in Figs. 8 and 9 wherein a plurality of stocking forms 71 are pivotally mounted in aligned sockets 72 in a carrier 73, each corresponding to the similar element in the previously described embodiments. The sockets 72 may be in a single series like the sockets 66 or they may be in two converging series like the

sockets

34 and 35. To provide for automatic positioning of the forms for the removal and replacement of the stockings, the forms are connected at their outer ends by flexible ligaments, in the present instance, chains 74. The chains are connected to the forms at the bottom of the end plates so that the chains do not interfere with the placement of the stockings on the forms. It will be apparent that as each form is pivoted in the socket 72 from the position indicated at 71a to the position 71b, the chain 74a will carry the forms 710 into the position 710. Because of the flexible character of the chain, it is possible to adjust the angular position of the form to the position found most desirable for the removal and repllacement of the stockings, for example, as shown at While particular embodiments of the invention have been herein illustrated and described, it is not intended to limit the invention to such disclosure, and changes and modifications may be made therein and thereto within the scope of the following claims.
