ATTYS Patented Mar. 28, 1950 MECHANISM FOR REPAIRING AND HEAT- TREATING REPAIRS OF NYLON HOSIERY Saul Sigel, Manchester; N. H., assignor to M. K. M. Hosiery Mills, Inc., Boston, Mass., a corporation of Massachusetts Application December 2, 1948, Serial No 63,088

8 Claims. 1 In the manufacture of nylon hosiery a considerable fraction of the goods contains small holes which it is necessary to repair, and in order that such repairs shall not be noticeable in the; I

final product and the goods be of first quality, a heat treatment of the repairs is necessary. It has heretofore been usual practice to inspect the hose after manufacture and if necessity for repairs is evident, the goods are mended while supmend and then place the mended area on a pad, 1

and bring a heated iron against it.

It will be noted that this method requires two operatives to mend and then heat treat the goods, and that it is necessary for the second operative to carefully examine the goods to re-locate the" mend before performing the heat treatment.

An object of the present invention, therefore, is to provide means by which both the mending and heat treatment may be performed by the same operative and without any necessity for relocating the mend before applying the heat treatment.

This is accomplished, in accordance with this invention, by providing a mending cup with an interior pad so that the goods may be mended pad may be projectable above the rim of the cup for the pressing action, if desired. or the pad may be permanently located somewhat below the cup rim and the pressing iron may be sufiiciently smaller than the cup rim so as to be brought down into pressing relation to the pad without produc--' ing undue distortion of the goods adjacent to the cup rim.

This application is a continuation-in-part of my application Serial No. 48,563, filed September 10, 1948, for Mechanism for repairing and heat treating repairs of nylon hosiery, now abandoned,

For a complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is a vertical sectional view to a larger scale on line l-I of Figure 2 through a work table and showing a mending cup provided with a supporting pad, the mending cup being in position for the heat treatment.

Figure 2 is a top plan view of the table showing the mending cup out of heat treating position and in convenient position for the mending operation.

Figure 3 is a view similar to Figure 1 but showing a modification.

Referring to Figures 1 and 2, at l is indicated a table having at a convenient location therein a vertical hole 2 therethrough. Mounted beneath the table and arranged to be projected upwardly through the hole 2 is a plunger 3 which may be provided with a stop shoulder 4 to limit the upward extent of its projection. At 5 is shown a mending cup provided with an outwardly flared base portion 6. This cup may be moved over the top of the table I from a position shown in Figure 2 forwardly of the hole 2 to a position over the hole 2 shown in Figure 1. The forward position is convenient for the operator to place the goods to be mended over the top annular rim 1 of the mending cup with the portion to be mended within the rim of the cup. The goods may then be mended in the usual manner.

The cup 5 has vertically slidably mounted therein a stem It which carries a pad H on its upper end, the cup thus serving as a pad support. This pad is normally depressed below the top rim of the cup as shown in full lines in Figure 1, and in this position the lower end of the stem I0 is sufficiently high so as not to interfere with the sliding motion of the cup along the top of the table. As shown the stem i0 is mounted within a tube I2 provided with a longitudinal slot l3 therethrough. Though this slot extends a cross pin it carried by the stem l0 and bearing on the extended end portions of the pin it outwardly of the tube I2 is a coil spring 15. This coil spring surrounds the tube I2 and reacts between the pin l4 and a suitable sleeve l6 secured within and to the wall of the cup. The tube l2 and the sleeve it constitute a guide for the stem ID. This spring l5 insures that in free condition, the stem it is in its depressed position as shown in full lines in Figure 1, so that the pad I l is well below the top margin of the cup where it cannot interfere with the mending operation of goods supported on this rim. In fully raised position the top face of the pad is preferably slightly above, say, 4 inch above the top of the cup.

The cup 5, with the stem and pad therein, may be moved rearwardly into cooperative relation with a suitable locating hold-down plate 29 which is shown as a block provided with a semicircular undercut recess 2| beneath which th flaring lower base portion 6 of the cup may be engaged.

This holds the cup down, while the plunger 3, which is in substantial alinement with the stem it when the cup is in cooperative relation to the hold-down, is lifted.

Positioned spaced above the cup when it is in its rearward position in cooperative relation to the locating hold-down 20 is an iron 25 which may be electrically heated and its temperature controlled by a suitable thermostat as is well known in the art. This iron 25, as shown, is carried by a gooseneck supporting bar 26 which has a vertical portion 27 slidably guided through a tubular guide 28 having a supporting flange 29 at its lower end secured to the top face of the table I. The iron 25 is thus mounted for vertical motion in substantial axial alinement with the plunger 3 and with the pad ll when the cup is in its rearward position in cooperative relation to the hold-down 20.

While the goods are supported on the cup rim in convenient forward position for the mending operation, this operation is performed and the cup with the goods supported thereon is then pushed rearwardly by the operative beneath the iron 25 and into cooperative relation to the holddown 20. The pad is then lifted to properly support the work and the iron is brought down into cooperative relation to perform the desired heat treatment.

The means for so moving the pad and the iron are shown in Figure 1. The lower end of the bar 21 which carries the iron is provided with a head 3!! with which engages the outer end of a lever 3! which is fulcrumed at 32 to a bracket 33 depending from the table I. Intermediate to the ends of this lever 3! it is connected by a link 35 pivoted thereto at 36 to a second lever 31 on the pivot 38. This lever 31 is a, floating lever, one end being pivoted at 39 to the lower end of the plunger 3 and the other end connected as by a pull rod 40 to any suitable actuating means, as, for example, a pedal (not shown) which may be depressed by the operative. When the pedal is so depressed, lowering the rod 40, the floating lever 31 is rocked about the pivotal axis 38, lifting the plunger 3 and the stem Ill and bringing the pad l i into its upper supporting position. The depression of the rod 40 also pulls downwardly on the link 35, swinging the lever 3i downwardly against the action of a spring 45, thus lowering the iron. The floating lever arrangement permits equalization of these motions so that the pad is lifted to its desired height with its upper face approximately even with or slightly above the top rim of the cup, and the iron is brought down with the desired amount of pressure to press the goods against the pad.

On releasing the pedal, the iron 25 is lifted from the goods by the spring 45 and the plunger 3 is depressed, freeing the pad I! so that it may lower into the cup, whereupon the mended and finished goods may be removed and the cup may be moved out of engagement with the holddown into a convenient position for the operative to apply other goods to be mended over the top face of the cup.

In Figure 3 a modified construction is illustrated in which the pad I la is permanently fixed within the mending cup 5a with its top face sufficiently spaced below the rim of the cup so as not to interfere with the mending operation. As shown, the pad Ha is secured in position in the cup by screws 50. The heated pressing iron 25a employed with this cup is sufliciently smaller in diameter than the cup rim Ia so that it may be brought down into pressing relation to the pad Ila, as shown in dotted lines in Figure 3, without producing undue distortion of the goods between its margin and the rim la. Since no lifting of the pad is required with this construction, the mechanism for depressing the iron is simpler than that shown in Figure 1, the rod 40a then being directly connected to the lever 3m, which takes the place of the lever M of Figure 1. The member 20 then acts merely as a locating plate having no hold-down function since no upward pressure is exerted on the cup 5a in connection with the pressing operation. In use the operator first places the goods over the cup rim while the cup rests on the table in convenient position, the portion to be mended being positioned within the area bounded by the cup rim and While the goods are so held, mending is effected in the usual manner. The cup with the goods thereon is then moved over the table into the locating plate and the iron is then brought down to press the mended goods against the pad to complete the treating operation, the goods then being removed and the cup positioned in convenient position for the operator to effect the next mending operationv From the foregoing description of an embodiment of this invention it should be evident to those skilled in the art that various changes and modifications might be made without departing from the spirit or scope of this invention.
