IN VENTOR" S. B. SCHWARTZ JOSEPH MULLER ATTORNEY Patented Apr. 6, 1954 TRANSFER PRINTING MACHINE Shepard B. Schwartz and Joseph Muller, Nashville, Tenn., assignors to May Hosiery Mills, Nashville, Tenn., a corporation of Tennessee Application January 15, 1952, Serial No. 266,613

12 Claims. (Cl. 41-1) This invention relates to printing, and more particularly to an apparatus for applying information or identifying marks to textile fabrics such as hosiery.

Heretofore, particularly in the hosiery trade, it has been customary to appl identifying marks and the like to such hosiery by a strictly manual operation in which the desired marks are in the form of a transfer carried by a paper tape, the transfer or printing being eifected by applying a hot iron to the reverse side of the tape, and with the. transfer ink in contact with the fabric. Needless to say, this is a time consuming and ineflicient operation and has materiall contributed to the manufacturing cost of such hosiery.

Also in the past, numerous machines for accomplishing such marking have been proposed, but these machines have presented serious drawbacks, one of which is the proper registration of the printed matter with the iron for applying the same. Likewise, proper iron operation to prevent scorching or burning has presented a problem with the result that no satisfactory, relatively inexpensive and efficient machine for this purpose has heretofore been available.

It is accordingly an object of this invention to provide a transfer printing machine which may be economically constructed from readily available parts and materials and which will eificiently operate to perform its intended functions.

It is a further object of the invention to provide an automatic transfer printing machine in which means are provided for feeding transfers in the form of a tape and in which means is also provided for automatically and accurately registering each transfer with the applying means. It is a further object of the invention to provide an automatic transfer printing machine which may be adjusted to accommodate various types and sizes of fabric articles.

A still further object of the invention is the provision of an automatic transfer printing machine in which the transfer may be automatically and accurately registered regardless of the size of such transfer. Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Fig. 10 a fragmentary detail view of the transfer tape and transfer as applied thereto; and

Fig. 11, a top plan view of the automatic trans fer printing machine of this invention.

With continued reference to the drawing and particularly Figs. 1 and 2, there is shown an automatic transfer printing machine constructed in accordance with this invention and comprise ing a supporting standard l0 upon the upper end of which may be secured by Welding or the like, a block ll. A complementary block l2 may be secured to the upper surface of block I l by screwthreaded fastening means IS. The abutting faces of the blocks H and I 2 may be provided with longitudinal complementary recesses which serve to slidably receive and clamp in adjusted position a horizontally extending supporting member'l l. Secured to one end of supporting member M by a screw-threaded fastening means I5 is a vertically disposed cylinder l6 from which the re:- mainder of the mechanism is supported.

As best shown in Fig. 3, cylinder"; is provided with a bore I! which serves to slidablyreceive a piston l8 having packings l9 at each end thereof. Secured to the piston l8 by a pin or the like 2!! is a piston rod 2| which is slidably received in an aperture 22 in an end closure 23 threadedly engaged with the lower end of the cylinder 16 at 24. In order to provide a fluidtight seal at the lower end of the cylinder It, a gasket 25may be positioned between an annular flange 26 and the lower edge of the cylinder I6, gasket 25 being tightly clamped in place by the screw-threaded engagement 2%. Also, in order to prevent leakage of fluid from within the cylinder 16' aroundthe piston rod 2-! there may be provided 'a" packing 21 secured to the closure 23 and slidably engaging the surface of the piston rod M to prevent leakage of fluid from the bore I! of cylinder it. Obviously, if desired, other types of packing 2? may be employed, such as the conventional gland or stufiing box, but with the pressures employed in this apparatus, in all probability a packing 2"! of the oil seal type will be satisfactory. Fluid pressure is-supplied to the upper end of bore I? through a conduit 28 and to the lower end of bore I! through a conduit 29.

The lower end of piston rod 2| extends through an aperture in a boss 30 projecting from the upper surface of a cross-head. may be secured to the cross head el by a pin or other equivalent means 32.

The solenoid valves are energized in the proper sequence to perform the necessary operations of the machine and the electrical circuit and manner of operation of this control circuit will be later described.

Fabric articles to be printed by the machine of this invention may conveniently be placed on the'upper surface of a plate I46 forming acircular feed table provided with a depending flange I41 which serves to protect the operator from injury and to conceal the mechanism located beneath the table. Plate I46 may be provided with spaced circular tracks I 48 secured to the under surface thereof by welding or the like, tracks I46 being provided with annular grooves I49 which serve to receiverollers I50 mounted in the upper ends of supporting legs or standards I5I. A sufiicient number of legs I5I and rollers I50 may be provided to suitably support the feed table I 46.

Driving means for the feed table I46 is provided in the form of a motor I52 having a power output shaft I53 coupled to a speed reduction gearing I54 which in turn is coupled to a drive shaft I55 having cams I56, I51, and I58 disposed thereon. Drive shaft I55 in turn is coupled to a ratchettype or other suitable clutch I59, the output shaft I60 of which carries a bevel gear I6I. Gear I6I meshes with a bevel gear I62 carried by a vertically disposed shaft I63 journaled in bearings I64, carried by cross braces I65, sup- Secured to the shaft I63 adjacent the upper end thereof is a spur gear I66 which meshes with a circular rack I61 carried by a circular angle member I68 secured to the plate I46 of the feed table. Cams I56, I51, and I58 on drive shaft I55 engage switches I69, I10, and IN to actuate the same in proper timed sequence and such actuation in connecting with the operation of the machine will be later described.

The ratchet type or other clutch I59 is of conventional construction and serves to automatically rotate the table I46 in periodic step-by-step movements. The clutch I59 automatically engaging and disengaging to accomplish such movement, the drive shaft I55 coupled to such clutch being continuously rotatable.

The control circuit as best shown schematically in Fig. 9 includes in addition to the micro-switch '13, cam operated switches I69, I10, and I", a limit switch I12 secured to the cylinder I6 and having an operating plunger I13 engageable by a finger I10 carried by the piston rod 2| and secured in place by the pin 32. Finger I14 is operative to engage the plunger I13 and operate the switch I12 when the iron 33 is in uppermost position and upon downward movement of the iron 33 the finger I14 is disengaged from the plunger I13 and allows the switch E12 to return to its normal inoperative condition. The table drive motor .I52-is1contro1led by a switch andthis '7 motor runs continuously during-.the; operation of:the-machine..

In the operation of the:printing machine of this invention, and: assuming the, table drive motor; I52. to be: operating,,the; tazble I46 will rotate intermittently: a predetermined distance by -reason of the-action of clutch-I 59, and; textile articles; to; be printed El'IGgDlELCGd on, the; table I465 and ;held in; position byv any, desired means. These articles are. advanced. beneath the tape 4.5.,carrying;the-transfers 46; tape 45. being, guided by. roller 9 I and by. roller: I16. supportedfrom spacedarms !,'";Whlh are attached to bracket 3.52. Eacharticle tOtbB; printedcomes: to rest be: neathathetape 45' and directly beneath the iron 33.;v Atthistimeycam operatedswitch I'II closes to-energizesolenoid I30. and'solenoid. hi3, which admitsfluid pressure through conduit .28 to .the upperyendgof: cylinder it, thus moving the iron 33; downwardly to transfer the ink 48. from tape 45i-to;th e article to be printed. Upon completion of this; printing operation, cam operated; switch IiI closes a second setof contacts. to energize solenoid 31' and solenoid I42, thus introducing fluidpressureto the lower end of cylinder IEand retracting iron 33. Solenoid valves I54 and I45 permit-the; escape of fluid pressure from the cylinder- I6; during movement of the piston I8 in suehcylinder. The table I46; then moves another step to presenta secondfabric article to beprinted;

Since; the transfer, 46. isonly suificientfor one printing operation, it is necessary to advance the tape 45 and bring a. second transfer into registry with the-iron 33ia-fter; the completion of a printing operation. This advancement of'the tape 45 is accomplished by the mechanism above described, and-exaet registry of the transfer 46 is obtained by actuation of the micro-switch l0. Actuation of: this switchis caused by the transfer: 46'; passing betweenthe rolls. 64 and IS, the thickness of the transfer ink being sufficient to move. these rolls apart andpivot the rocker arm I3.a-bout thepivot pinlfi, thus moving the'push rod 8 2;away fromthe'plunger 'I'I ofmicro-switch Ill, and allowing this switch to close.

Assumingv that a printingoperation has just beencompleted and. a transfer-46. is disposed between the rolls 6.4 and I9 with. the microeswitch "IGjclosed to complete the circuit to solenoid valves I32 and M5, at this time cam operated switch I69; is open in order to interrupt the circuit to these-solenoid valves. and prevent: energization of the same. Upon return of iron 33 to its uppermost position the finger I'I4:will-engage plunger I13 of. limiteswitch- I12, closing this switch to energizesolenoid valves I33 and I44, thus admitting fluid pressure to one end of the cylinder I 53 and, engaging the driven clutch member I85 with the driving clutch member ISI- to rotate drive roll I04 and advance the, tape45 through the rolls Hand 19 from the tape supply roll 44.

Assoon as the transfer 46 has passed from between rolls 64 and 'Isthese rolls move toward each other toopen the micro-switch Hi and at the-same time cam operated switch hi9 closesto supply. current to thiscircuit in order that when the next transfer46 passes between rolls 64. and Hand closes micro-switch I this will operate to energize solenoid valves I32 and M which will disengage driven clutch member I65 from driving, clutchmember MI and stop the rotation of roll IE4. and themovement of tape M5 which results in accurately registering or positioningartransfer. 46 :beneath the iron 33'. During; the advancement of tape 45 camoperated switch I'ID opens, which deenergizes, solenoid valves I33;and I44, but the driven clutch member I05;will not be; disengaged from driving clutch member IG'I until micro-switch"!!! closes, since it is-necessary to introduce fluid pressure to the opposite end of cylinder II3..in order. to accomplish suchdisengagement of the tape pulling drive clutch.- Itwillbe seen that it is. impossible for the tape 45 to be moved. during downward movement of the iron .33 to initiate aprinting operation since immediately the iron 33 com: mences to, move downwardly, the finger -I14 is. disengagedfrom the plunger I13; thus opening the limit switch I12 and preventing introduction of fluid pressure to-the cylinder II 3.:t0. engage the driven clutch member with the driving clutch member IOI;, This movement is only-Vinitiated upon the upward movement of the iron 3?. to. close the limit-switch I12, after which-movement of the tape 45 is completely under control of the micro-switch ID actuated by the transfer 46 passing between the rolls 64 and I9;

It will be seen that by the above described invention. there has been provided a completely automatic transfer printing machine in which transfers may be supplied on a continuous paper tape and in which such transfers are accurately registered-with a transfer applying iron and in which the articles to be printed may be. automatically fed to the machine in timed relation to the operation of the various components thereof, the operation of the machinebeing accomplished through fluid pressur means controlled by an electrical circuit. The machine of this invention may be constructed-from readilyavaile able parts and materials and may be fabricated in such a manner that highly efiicient operation may be obtained over long periods of time without the necessity for frequent shutdowns for: repair and the like;

It will be obvious to those skilled in the art that various changes may be made inthe invention without departing from the spirit and scope thereof, and therefore the invention is not limited by that which is shown inthe drawing and described in the specifications, but only as indicated in the appended claims.
