Claims. (Cl. 41-1) This invention relates to a transfer applicator andmore particularly to an automatic machine for applying transfers to socks, and other items of wearing apparel.

It has been found desirable in the manufacture of socks, stockings, hose and other items of wearing apparel to mark the size and the manufacturers name or trade-mark on each article produced. In order to accomplish this, it has been standard practice in the trade to transfer letters, designs, colors or a combination of these from a strip of paper to the article by applying heat and pressure against the paper while it is in contact with the article to be marked. This transfer may be accomplished by using a domestic iron or by using other types of equipment.

Generally, the transfer or label to be applied to an article of clothing is first printed inversely at spaced in tervals along a strip of paper or tape. When used, a printed section of the tape is held on top of the article and the heating element is applied to the back of the tape; then, the next printed section is used to mark the next article in a similar manner and so on.

Recently, a device has been used which consists of i a heating element supported by a reciprocating arm so that, in order to mark an article the operator need only posi tion the article and the tape appropriately beneath the heating element. This process has materially increased the number of transfers accomplished by one operator in a given time; however, the continual handling and adjusting of the article and the tape to the proper position is very tiring to an operator.

Accordingly, it is an object of my invention to provide a device which will alleviate the difficulties described above and facilitate the handling and marking of articles of clothing and the like.

Another object of my invention is to provide a machine which will increase the number of articles which may be marked by a single operator in a given time.

Another object of my invention is to provide amachine for applying transfers to articles which when the articles are successively placed on the machine will automatically mark and stack these articles.

v Another object of my invention is to provide a machine for marking articles of clothing, as described above, .which is easily operated by an inexperienced operator'with less fatigue than has heretofore been occasioned.

Another object of my invention is to provide an automatic machine for marking articles of clothing which 2,776,569 Patented Jan. 8, 1957 ice sponding parts throughout the several views, and wherein:

Fig. 1 is a perspective view of a machine constructed in accordance with my invention.

Fig. 2 is a cross-sectional view taken alongline 22 of Fig. 1.

Fig. 3 is a side view of the machine shown in Fig. 1.

Fig. 4 is a view of a detail showing the pulley and ratchet driving mechanism of the machine illustrated in Fig. 1.

Fig. 5 is a view of a detail showing the operation of the interlock system.

Referring now in detail to the embodiment chosen for purpose of illustration, and to Figs. 1 and 2 in particular,numeral 10 denotes generally a rectangular box-like casing which is open, as shown in Fig. 1, at its top. Adjacent this open top are positioned spaced roller shafts 11, 11 retained byjournals 12 mounted onbrackets 13 in Fig. 1. Fixed concentrically and centrally of shafts 11, 11', respectively, are solidcylindrical feed rollers 14, 14, which are provided with peripherial grooves adjacent their ends to receive spacedcontinuous belts 15, 15' which extend parallel to each other between the two rollers to convey articles to be marked across the top ofcasing 10.

7 As shown in Fig. 2, areel supporting pan 16 is mounted withincasing 10 along an end thereof adjacent roller 14'.Rollers 17 are mounted transversely between the sides ofpan 16 and are spaced on an arc to supportreel 18 thereon.Arm 19 extends up from one edge ofpan 16 and is provided with a pivot pin on which is mounted for rotation aroller 20 which acts as a guide for thepaper marking tape 21 unreeled fromreel 18. As seen in Figs. 1 and 2, awindow 22 is provided within the end ofcasing 10adjacent pan 16, through whichreel 18 may be inserted and then mounted to rest freely onrollers 17 withinpan 16. Whenreel 18 is mounted properly onrollers 17 withinpan 16,tape 21 leading fromreel 18 is passed overroller 20 and then overrollers 14 and 14 so thattape 21 is spaced betweenparallel belts 15, 15" and in the same plane therewith.Tape 21 is provided with certain desired marking or labels 23 at spaced intervals along the top surface of thetape 21 so that when heat is machine is inexpensive to manufacture, durable in construction, efficient and inexpensive in operation.

Other and further objects and advantages of my invention will become apparent from the following disclosure when taken in conjunction with the accompanying drawings in which like figures of reference designate come applied to the back of the paper tape, the printed material or label thereon may be transferred as desired.

As illustrated in Fig. 2, anarm 24 is pivotally mounted on the end wall ofcasing 10adjacent roller 14. Arm 24 supportspressure roller 25 which rides against the lower portion ofroller 14, and aspring 26 is connected toarm 24 and to thecasing 10 to urgeroller 25 againstroller 14. After passing overroller 14,tape 21 is fed betweenroller 14 androller 25 and down into the void lower section ofcasing 10; therefore, whenroller 14 is rotated,tape 21 will be unreeled fromreel 18 and pulled along in the same plane withbelts 15, 15'.

Positioned somewhat centrally transversely withincasing 10, is heating element, supportingbracket 27 which is fixed to the sides ofcasing 10 in a horizontal position.Bracket 27 is provided with an aperture in its central portion, through which is passed anupright rod 28 which is journaled for vertical motion withinsleeve 29 which is fixed to the lower side ofbracket 27.

Mounted on the upper end ofrod 28 so as to be positioned between belts i5, 15 is a conventional rectangularshapedelectric heating element 30 which is activated through electrical cables (not shown). At the lower end ofrod 28 is atransverse pivot pin 31 which is fixed torod 28 and iides within a slot within one end oflever arm 32. The other end oflever arm 32 is fixed toshaft 33 which shaft passes throughcasing 10 and is engaged bylever 34 on the outside ofcasing 10. It will be apparent therefore, that whenlever 34 is moved up and down,heating element 30 will be moved away from or towardtape 3 21.Latches 35 and 36 are provided on casingadjacent lever 34 to act as a catch for thelever 34 and therefore allow proper positioning ofheating element 30, eitheradjacent tape 21 as shown by solid lines in Fig. 2 oraway fromtape 21 as shown by the broken lines in Fig. '2.

As illustrated in Fig. 2, abrace 37 is mounted upright withincasing 16 and supportstransverse axle 38. Axle 38 is journaled for rotation Withinbrace 37 and extends through an appropriate aperture in a side wall ofcasing 10. Pulley 39 is concentrically fixed toaxle 38 betweenbrace 37 and the wall ofcasing 10 and is driven by acontinuous belt 46 which is driven from agearhead motor 41 mounted onbracket 42 transversely withincasing 10. Also fixed concentrically to theaxle 38 isrocker disc 43 which actuates connectingrod 44 and'tilts platform 45 which is hinged tocasing 10 bypiano hinge 46. Fixed concentrically toaxle 38 outside ofcasing 10 is acircular disc 47 having acam 48 fixed to its inside face as illustrated by broken lines in Fig. 3.

Referring now in particular to Figs. 3, 4 and 5,pivot pin 49 is fixed to the outer face ofdisc 47 adjacent the periphery thereof, and attached topivot pin 49 is aflexible cable 50 which loops around asolid cylinder 51 rotatably positioned on shaft 11.Cable 50 rides within helical grooves oncylinder 51, as shown in Fig. 4, and its end is fixed tocylinder 51 by screw 52. Asecond cable 53 is fixed tocylinder 51; the outer end ofcable 53 extends down and is fixed to spring 55 which in turn is fixed tocasing 10, as illustrated in Fig. 3. Acylindrical flange 56 made integrally withcylinder 51, as shown in Fig. 4, retainspawl 57 pivotally mounted on its face adjacent the periphery thereof. Pawl 57 drivesratchet 58 which is fixed concentrically to shaft 11. Therefore, asdisc 47 rotates to pullcable 50,pawl 57 acts againstratchet 58 to rotate shaft 11. Asdisc 47 continues its cycle of rotation, spring 55 acts throughcable 53 to rewindcable 50 oncylinder 51, thus allowingpawl 57 to pass overratchet 58 and therefore not rotate shaft 11.

Mounted for vertical motion within alignedjournals 59, 59 oncasing 10, is standard 60 which is positioned abovecam 48 so that thelower end of the standard will ride against the cam. Fixed to the upper end of standard 60 is a presser plate supporting arm 61 which is retained in place by a set screw (not shown). Arm 61 extends at right angles from standard 60 and supportspresser plate 62 in a position overheating element 36.Presser plate 62 is faced with aresilient material 63 on its bottom surface; this resilient material may be rubber, neoprene, or a sponge material.Guide staff 64 extends from the top edge ofcasing 16 and through an aperture in arm 61 so that as arm 61 is moved up and down by the reciprocating action of standard6i presser plate 62 will remain in the same vertical plane. Acoil spring 65 has one end fixed to arm 61 and the other end of the spring is fixed to casing 10 so that standard 66 at all times is urged againstcam 48. Aninterlock pin 66 depends from arm 61 and is so positioned that it is above the edge ofcasing 10 and as standard 60 moves down, the pin will normally pass through a drilledrecess 67 passing partially down through the wall ofcasing 10.

As illustrated in Fig. 5, the interlock system, which is a meansbywhich interlock pin 66 is blocked from enteringrecess 67, consists generally of an upstanding brace fixed to the upper edge of casing 10 which pivotally retains an interlock arm that extends outwardly and downwardly overtape 21. Alever arm 70 is fixed to interlockarm 69 at a positionadjacent brace 68 and is pivotally fixed at its end to shutter bar '71 which extends as illustrated in Fig. 5 to a position whereshutter 72 onshutter bar 71 can selectively block the entrance ofinterlock pin 66 intorecess 67.

From the foregoing description, it will be obvious that an operator may place articles to be marked over each of the transfers 23 as they first pass over roller 14' and these articles will rest on and be carried along bybelts 15, 15' underinterlock arm 69 to a position beneathpresser plate 62. It will be apparent from Figs. 2, 3 and 5 that an article positioned beneathpresser plate 62 will lift thisinterlock arm 69 so thatshutter 72 will uncoverrecess 67 and therefore not interfere with the passage ofinterlock pin 66 or the operation ofpresser plate 62. When an article is positioned beneathpresser plate 62,disc 47 is at such a position of its cycle that shaft 11 will not be rotated and thereforetape 21 andbelts 15, 15 will be stopped. With continued rotation ofdisc 47, the recess portion ofcam 48 will position itself so that standard 60 drops into this recess and therefore causespresser plate 62 to press against the article positioned thereunder causing the article and the transfer tape to be pressed againstheating element 30. With continued rotation ofdisc 47,presser plate 62 is lifted and the article will be carried bybelts 15,15 and deposited onplatform 45. My invention is so arranged that as each article is deposited onplatform 45, the platform will tilt up as illustrated in Fig. 2 and thus stack the articles in any suitable container (not shown) placedadjacent casing 10 belowplatform 45.

It will be apparent that if no article is placed over a certain transfer 23, as this transfer passes over theheating element 30 theinterlock arm 69 will not be lifted, because the necessary thickness of an article to be marked is missing, and the downward movement ofpresser plate 62 will be interrupted byshutter 72blocking recess 67 and therefore blocking the downward movement ofinterlock pin 66.

It will be obvious to those skilled in the art that many variations may be made in the single embodiment disclosed for purpose of illustration without departing from the scope of my invention as defined by the appended claims.
