4 Claims.

This invention relates to improvements in transfer machines and methods by which trademarks, legends, brand names or other indicia are transferred from a movable carrier to articles of clothing, such as hosiery, or other articles to which they are to be applied. The present invention may be embodied, for example, in the type of machine which is described and claimed in United States Letters Patent No. 2,323,843, granted July 6, 1943, on an application of Henry Richter, John H. Wahlbeck, and Leonard S. Kleinfeld.

It is desirable to mark hosiery and other articles with indicia indicating trade names, sizes, quality or other information transferred from a movable carrier such as a roll of tissue paper on which the indicia. are imprinted in spaced relation by means of wax or other material having a relatively low melting point. When a portion of the carrier bearing the wax imprint is pressed against the surface of the article to be marked and heat applied, the wax melts and the indicia carried thereby is transferred to the article. The article is then moved and the carrier shifted to bring another wax imprint into engagement with another article and the operation is repeated. A difficulty which has been encountered in the operation of such transfer machines heretofore has been that the pile of articles to be marked or labelled tends to shift its position between successive operations so that the indicia do not appear in identical locations on diiierent articles of the same group or class. Another difiiculty has arisen from the fact that the pile of hosiery usually does not have a flat or horizontal top surface so that the transfer of the indicia has sometimes been incomplete.

The principal object of the present invention is to provide apparatus and methods for transferring indicia to a series of articles according to which the successive articles are held in a prede termined location so that the imprints are located in identical positions on successive articles. A further object is to provide a transfer machine having a support on which a pile of hosiery or other articles is secured in position by the application of suction so that, as the transfer operations take place and the articles are successively removed from the top of the pile, the indicia transferred from a carrier are located in substantially identical positions on the several articles. Another object is to provide a transfer machine comprising a self-aligning imprinting iron by which the indicia is heated and trans-- ferred effectively even though the hosiery pile may have an uneven top surface. Still another object is to provide improved means for controlling the intermittent operation of the transfer machine while the indicia are being applied to the articles to be marked. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanying drawings in which one embodiment is illustrated. In the drawings,

Fig. 9 is a circuit diagram of the electric connections of the imprinting iron, the motor by which the apparatus is driven, and other electrically operated parts which are included in the construction.

As shown in Fig. 1, the invention is embodied in an upright cabinet In having a stationary front panel Illa, a hinged front door lflb, a horizontal top or worktop 10c,- and end walls Hid. The stationary front panel lEa has its lower part recessed toward the rear as shown at We to provide space for the feet of the operator and the space behind the hinged door lfib is adapted to contain a series of shelves upon which the hosiery or other articles to be marked may be placed within convenient reach of the operator.

The top Hie of the cabinet is preferably formed of plated metal or stainless steel having a smooth surface and it is adapted to form a support for a like wound in the form of a coil on a reel :5. The

free end of the carrier tape hi extends downwardly from the reel and passes beneath a roller E6 carried by a bracket I! which is secured to the top I30 of the cabinet at the rear of the pile of hosiery. The operator who occupies a position in front of the stationary panel Ida moves the tape by grasping the free end thereof and pulling it in a forward direction until one of the indicia i3 is located in proper position with respect to the uppermost stocking of the pile, whereupon the heated imprinting i on !2 is caused to move downwardly to melt the wax by which the indicia is carried and thereby cause the indicia to be tran ferred to the surface of the uppermost stocking.

After one transfer has been made, the imprinting 1 iron 12 is elevated and the operator then lifts the tape, folds over the uppermost pair of stockings and then moves the tape in a forward direction to locateanother indicia on the tape in the same position over the uppermost stocking of the next pair, whereupon the imprinting iron 12 is again lowered to repeat the transfer operation.

The reel i is in the form of a spool mounted upon a shaft [3 which is journaled in a bracket 28 extending upwardly from the cabinet top 130 to which it is secured by studs 2|, as shown in Fig. 3. The shaft is has a threaded extremity 13a which engages an aperture in the top end of the bracket 2c and this threaded part is engaged by a nut 22 so that the shaft is detachably secured in position. The spool i5 has a flange 55a at one end against which the inner portion of one end of the coil of tape it is seated and the reel is secured on the shaft it by means of a washer 23 and a screw 2 In order to control the freedom with which the tape it may be withdrawn from the coil, the shaft is has mounted on the inner end thereof a drum 25 engaged by two friction brake springs 2'3 carried by the stationary block 2'! attached to the standard 23. An adjusting screw 23 threadedly engages the springs 26 and may be manipulated to adjust the pressure of the brake springs 23 on the drum 25.

The imprinting iron i2 is mounted upon the lower end of a hollow tube 33a which depends from the outer end of an arm 33b mounted on a post 330 which reciprocates vertically in a guide 3| having a flange 3 i a which is secured to the easing top We. The post 3%, being of square cross section, is held against rotation in the guide 3| of similar cross section, although free to move vertically.

As shown particularl in Fig. 3, the tube 39a of the U-shaped iron support fits into a socket in the arm 381) where it is detachably secured in r 4 place by setscrews 33d. The lower end of this tube is threaded, as shown in Fig. 7, for engagement with the threaded aperture formed in the upper end of a housing 33 which constitutes the supporting frame of the imprinting iron [2. The upper wall of this housing is provided with a transverse slot 33a and a clamping screw 34 extends through this slot and engages a threaded aperture in the wall of the housing so that when the screw is tightened the parts on opposite sides of the slot 33a are drawn together, thus clamping the housing 33 against rotation with respect to the tube 33a. The housing 33 has downwardly and outwardly flaring lateral walls which terminate in outwardly directed flanges 33b to which there is attached a body of metal 35 constituting the heated plate or iron proper which is heated for the purpose of causing the indicia carried by the tape [4 to be transferred to the stockings in the pile H on the casing top. In order that the heated plate or imprinting member 35 may have some relative movement with respect to the casing 33 so as to conform to irregularities in the slope or surface contour of the uppermost stocking in the pile, the member 35 is attached to the flanges 3312 by means which permit some relative movement of these parts. At diagonally opposite corners of the rectangular iron 35, the parts are secured together by screws 33 which somewhat loosely engage apertures 330 in the flanges 33b and which have reduced extremities 38a threadedly engaging recesses 35a formed in the member 35. At the ends of the threaded portions 3600, the shoulders 36!) of the screws 35 seat upon the upper surface of the member 35, thus providing a clearance 38 between the member 35 and the bottom surface of the member 33 which allows some relative movement of the parts 33 and 35. At the other diagonally opposite corners of the member 35, the member 35 and the flanges 331) are provided with oppositely disposed recesses in which are seated the ends of coil springs Bl. These coil springs normally maintain the members 33 and 35 in the spaced relation shown in Fig. 7, wherein the clearance 38 is of the same magnitude around all parts of the flanges 33b. However, if there is any unevenness or variation in slope of the upper surface of the uppermost stocking in the pile, the member 35 is permitted to tilt with respect to the member 33 due to the presence of the springs 3'1 and the loose connections provided by the screws 36 so that the lower surface 355 of the iron proper is permitted to conform to the surface of the uppermost stocking and thereby bring about a complete transfer of the entire indicia carried by the tape M.

The iron proper 35 is heated by an electric heating element 42 which is embedded therein and which has its terminals niia extending upwardly within the chamber of the housing 33 where the threaded extremities are engaged by nuts is between which the lower ends of the conductors 44 and d5 which lead from a source of electric current are clamped. These conductors are embodied in an insulated cable 58 which leads downwardly through the tube 33a from the hollow arm 30b and the hollow post 330, the supply end of this cable being connected in the circuit below the table top 100. With the arrangement which has just been described, it is possible to effect a ready detachment of the housing 33 and the ironing element 35 carried thereby so that one imprinting iron may be interchanged with another of different size in order to accommodate the apparatus to the size and character of the indicia which are to be transferred.

The lower end of the post 300 of the iron supporting standard has a relatively fixed bracket on which there is mounted a roller 5| adapted to travel upon the peripheral surface of a cam 52 by which the imprinting iron I2 is caused to reciprocate vertically to and from its operative position. The roller 5| is maintained in contact with the surface of the cam 52 by means of a coil spring 53 which has its upper end attached to a pin 54 fixed in the lower end of the post 380 and which has its lower end attached to an eye bolt 55 secured in one of the angle bars 56 which form a part of the interior construction of the cabinet ID, as shown in Figs. 3 and 5. The cam 52 is eccentrically mounted upon a cam shaft 5'! journaled in a bearing bracket 58 which is attached by means of studs 59 to a table 60 carried by the frame members 56 behind the front panel Its. A spacing plate 5| is interposed between the table 60 and the flanges of the bracket 53. The table 68 is provided with a slot 60a into which the cam 52 may descend when it is rotated from the position shown by full lines in Fig. 3 to the position shown by dotted lines, corresponding to the movement of the imprinting iron I2 from the uppermost position shown in Fig. 3 to the operative position wherein it engages the carrier tape on the uppermost stocking of the pile. The cam 52 is adapted to be intermittently operated to cause the imprinting iron I2 to be lowered to its operative position each time that a new indicia on the tape I4 is brought to position over a new article on the pile II.

For the purpose of holding the pile of hosiery or other articles I I in the proper position on the casing top IIlc, this top is provided with an aperture I61 through which suction is applied to the lowermost article in the pile, it having been found that if the lowermost article is held stationary, those above it will remain in proper position due to their frictional contact with each other. Suction is applied to the opening IIlf through a hollow fitting 64 which has connected thereto a flexible tube 65 leading to the vertical pipe 65. This pipe has its lower end connected to the intake of a suction pump 61 which has its base plate secured to a plate 68 fixed on the table 60. The suction pump 61 has an outlet 69 which is protected by a screen Ill to keep dust and the like from entering the interior of the pump. The pump is driven by a pulley II fixed on its shaft and actuated by a belt I2 which extends therefrom to a multiple groove pulley I3 secured on the shaft of an electric motor I4. This motor is fixed on the table 60 and is in operation at all times when the transfer mechanism is being employed so that the suction is constantly applied through the opening Iflj in the top of the cabinet.

The motor III also serves to drive the cam 52 through connections which are shown particularly in Fig. 5. These connections comprise a belt l5 extending from the multiple groove pulley I3 on the motor shaft to another multiple groove pulley It on the shaft of a gear reducer I! which is mounted on the table 60. The shaft I8 of the gear reducer has fixed thereon a clutch member I9 having clutch teeth which are adapted to engage the teeth of another clutch member 85 which is splined upon the shaft 51 to which the cam 52 is secured. The shafts I8 and 52 have a telescoping engagement with each other, shown in Fig. 6, and when the clutch member 80 is moved into engagement with the clutch member 6 I9 the shaft 51 is actuated to rotate the cam 52 and thereby move the imprinting iron to its operative position. The cam is normally in the position shown in Fig. 5 wherein the imprinting iron is in its upper or inoperative position.

The clutch member is actuated by a clutch lever 82 which is pivoted on a fixed bracket 83 and which carries a pair of pins 84 engaging the annular groove 80a in the clutch member so that when the lever 82 is oscillated about its pivot, the clutch member 80 is moved longitudinally of the shaft 52 and into or out of engagement with the clutch member I9. The upper end of the clutch lever 82 is connected by a link 85 with another lever 86 which is pivoted at 81 on the bracket 83 and which is provided at its lower end with a tooth 86%; adapted to engage a recess 80b in the clutch member 80 when the clutch members are disengaged. The lever 86 and the lever 82 are normally moved toward the right, as viewed in Fig. 5, to disengage the clutch members, by means of a coil spring 88 which extends from the upper end of the lever 86 to a fixed bracket 89 secured to the table 60. When the lever 85 is rocked about its pivot, its motion is transmitted to the clutch lever 82, thereby actuating the clutch member 30. The movement of the lever 86 against the tension of the spring 88 is effected by a rod 90 which is connected by a pivot SI with the magnetizable core 92 of a solenoid 93 arranged to be connected in the operating circuit as hereinafter described. When the solenoid is energized, the magnetizable core 92 is moved toward the left as viewed in Fig. 5, with the result that the clutch members I9 and 80 are engaged, thereby causing the cam 52 to rotate with a resulting downward movement of the imprinting iron I2 under the influence of the coil spring 53.

When the clutch members are thus engaged the tooth 86a of the lever 86 is simultaneously disengaged from the recess 80!) and then rides on the end surface 800 of the clutch member 80 and holds the clutch members engaged until the recess 80b has completed one revolution.

The spring 88 then causes the tooth 86a again to engage the recess 80b and causes the clutch members 19 and 80 to disengage. This arrangement causes the cam 52 to stop in its normal position at the end of each revolution with the imprinting iron I2 in its elevated position.

In order that the solenoid 53 may be conveniently actuated to control the rotation of the cam 52 and the resulting movement of the imprinting iron, the cabinet I0 is provided adjacent the upper edge of the panel Iila with a switch actuating bar 95 shown particularly in Figs. 1 and '7. This bar has its ends secured to plates 95 which project inwardly therefrom and which have their end portions pivoted to brackets 97 attached to the panel Illa. The bar 95 is normally maintained in its uppermost position, shown in Fig. 1, by means of coil springs 98 which are interposed between bosses 97a formed on the brackets 97 and the heads of pins 99 slidably engaging apertures in these bosses. The heads of the pins engage the upper walls of the hollow bar 95, as shown in Fig. 7, and they are normally moved in an upward direction by the spring 98 to hold the bar 95 in its normal position.

When the bar 95 is moved downwardly by the pressure of the body of the operator against it, it actuates an electric switch I00 secured to the panel Illa and having an actuating plunger IIlI arranged to be operated by a pin I02 attached to the bar 95. When the switch It!) is thus closed, the solenoid 93 is energized to cause the clutch members '39 and 80 to engage, thereby causing the cam 52 to rotate through one revolution and efiect a downward and reverse movement of the imprinting iron I2. With this arrangement, the movement of the imprinting iron may be controlled by the body of the operator, leaving the hands free for the manipulation of the articles in the pile II and for the movement of the tape I4 by which the indicia are carried. A momentary pressure upon the bar 95 is sufficient to close the switch I88 and effect an actuation of the cam 52 through one revolution. If the operator continues to press on the bar 95 the cam 52 will continue to rotate without interruption to cause a series of working movements of the imprinting iron.

The electric circuit about which the imprinting iron I2, the electric motor I4, the solenoid 93 and other devices are actuated and controlled, is shown diagrammatically in Fig. 9. This circuit comprises line conductors I65 and I06 leading from a source of current supply to a terminal block Iil'I from which several parallel branch circuits lead to the different devices to be actuated. One of these branch circuits includes a pair of conductors I98 and IE9 leading to a double pole switch I I which is controlled by a push button I i i mounted on the panel Illa. When this switch III is closed it establishes the circuit of the motor I l through the conductors H2 and at the same time it connects the source of supply with two conductors IIS and Iii which lead to the solenoid 93. One of these conductors H3 has connected therein the switch Iii!) adapted to be actuated by the bar 95. Thus, the circuit of the solenoid 93 may be closed only when the switch I It has been actuated to cause the operation of the motor 14 which drives the suction pump and also supplies the power for causing the rotation of the cam 52.

The terminal block 101 also has leading therefrom a pair of conductors HT and H8 which lead to a double pole switch IIS adapted to be actuated by a member I23 located on the front panel Illa. When the switch H9 is closed it closes the circuit of the heating element 42 and also the circuit of a pilot light I22 which serves to indicate to the operator that the imprinting iron is heated. The bulb of the pilot light I22 may be located in any desired position, for example, within the housing 33 of the imprinting iron from which the light would be visible through the apertures 33d which are provided in the housing. The pilot light I22 and the heating element 42 are connected in parallel, being supplied with current from the switch H9 through conductors I23 and I241. The heating element 42 has connected in serie therewith a rheostat I25 adapted to be operated by a controlling member I26 mounted on the panel Ilia so that the degree of heat of the imprinting iron I2 may be conveniently regulated by the operator. The terminal block I61 also has leading therefrom a pair of conductors I21 which are connected through a switch I28 to a series of lamps I29 which may be located within the cabinet behind the door Ifib for the purpose of illuminating the shelves on which the articles to be marked are stored.

In the operation of this apparatus with hosiery, for example, the pile of hosiery, usually one dozen pairs, are placed upon the top I00 of the casing with the foot portions thereof positioned beneath the imprinting iron I2 and with other portions thereof extending over the aperture I0 Having closed the switch I It, the motor Ii then actuates the pump 6'! to cause suction to be applied through the opening I6) whereby the pile of hosiery is held in position. The several pairs of hosiery should be in vertical alignment with each other and with the stockings of each pair in exact alignment. A portion of the tape it is then withdrawn from the reel to cause one of the indicia It to be positioned over the desired portion of the foot of the uppermost stocking. The operator will have closed the switches He and II9 and with the stockings and the tape thus positioned, the bar $35 is then actuated to close the switch I35, thus energizing the solenoid es and causing the clutch members I9 and so to engage so that the cam is rotated to move the imprinting iron I2 downwardly until it engages the indicia on the tape Id which is positioned on the uppermost stocking. The application of the heat of the iron will melt the wax and cause the indicia to be transferred to the stocking and the imprinting iron I2 is then withdrawn by the rotation of the cam so that the operator can lift the tape, fold over the upper pair of stockings, and then move the tape to position another indicia over the uppermost stocking whereupon the bar is again actuated to cause another transfer to be made. The tendency for the pile of stockings to slip on the top of the casing during this operation is overcome by the constantly applied suction which holds the lowermost stocking in place even when the pile has been reduced to the point where only one pair of stockings is left. When all of the stockings of one pile have been marked, a new pile is put into position and the operation is repeated.

Although one form of the invention has been shown and described by way of illustration, it will be understood that it may be constructed in various other embodiments which come within the scope of the appended claims.
