In the construction shown, the structure comprises a portable platform or supporting structure 1 which supports an open 'rectanand drive rolls 8. The vertical members tween the vertical .giilartank 2, in'which the tapelA is moistened, and; vertical members 3- and 4, which form, with the transverse members 5, a sup port for a tape wringer 6, a drier element 7, with the transverse braces 10 and 11 be members 4. and 9,. form bearings and supports for the driving motor {12, and a-comp ete' tape re-winding mechamsm."

The ta e spools 13 are mounted on aremovable out of the rectangular tank 2., The frame 1ft, which might be termed the supply magazine, supports three tape spools on individual spool shafts 13 between two vertical members 15, one end of each spool shaft 13 fitting into a socket in one of the upright members 15, the other end being located in :a recess or slot 16, in which it is locked in position by 'a pivoted catch bearing 17. The

tape passes from the spools on one side of the tank to respective idlers 18 on the opposite side of the. tank. Between the spools and the idlers are placed vertical rods 19 forming slits through which the tape must pass-giv ng 1t a half turn in the liquid which act as guides for the tapes as they leave the idlers. Above the frame and over hanging the tank is ,placed a Wringer 6 IWhiCh is mounted at the junctions .of the vertical members 3, and transverse members {5. The wringer B'has a roll 22 which is mounted on a shaft 23 in the journals 24. On

the shaft 23 is also mounted a gear wheel '25 which meshes with a similar gear wheel- ;26 which drives a roll 27. Pressure between icoacting surfaces of therolls 22 and 27 is maintained by means of springs 2-8, which act between the bearing blocks 29 of the roll 27, and the lower surface 9f the wing nuts 30.

Substantially uniform tension is maintained on the tape by having it pass over the edge of the angle iron 31 to a tension frame 32, shown in Fig. 6. The tension frame 32 is secured to vertical members 3 by pivots 33,. Suitable rollers 34ers mounted on the tension frame 32 in such manner as to prevent endwise displacement. A. slight addi-' tional tension isalso maintained by arms 35, which are pivoted to the platform 211236, and

asv fit passes from the spool 13 to theidler 13. 7. Arms 20, secured to the frame, have eyes 21, elevation of a tape 'shrinklng machine constructed according to rsremcaflqnbf m' a nt Patented Sept. 10, 1912.

me 14, which is slidable into and which are provided with-pr0lig 37 which engage and guide the tape in the passage from the rollers 34. By running, the tape down over'the tensionframe, therejis provided an extended loop between the bath and the drier where shrinkage occurs, and the tension mechanism tends to keep the tape taut Llld readily, yields to any irregularities in the tape during shrinkage.-

Above the transverse member 5 is supported a curved metal plate 38, which is provided with a heater, shown in the drawmgs in the form of two gas burners 39" with the usual mixing tubes 40 and as supply pipes 41. The tape is delivere to the curved metal late 38 over a guide roll 42, above which is mounted a smoothing roll 43. For

, convenien'ce in threading thetape between 4 site end of the roll being the guide and smoothing rolls, the smoothing roll is mounted on' a pivot 44 the oppoprovid handle-45. Guide pins 4 are plaoedat the delivery end of the curvedplate 38 to prevent shiftin of the tape on the drying 25 surface. A thermometer 38f is connected to the plate 38 to enable'the operator to accurately control the temperature of said plate.

In its delivery from the drive rolls '8 to' winding shafts 53, being removably mounted on said shafts by means of a slidable cone bearing 54,which coacts with the wing nuts 55 which are threaded on the end of the shafts 53. The spool winding shafts 53 are all rotated in the same direction by means of five similar gear wheels 56, three of the gear wheels 56 being mounted to rotate with the spoolshafts 53, two of the gear wheels being mounted on shafts 57 intermediate of the spool driving gears 56. Oneof the spool shafts 53 is provided with a p'rolongatlon 53 and is journaled in an outer bearing 58.

Between the outer'bearing 58 and the-frame is a driving sprocket wheel '59. All of theshafts' 53 and the shafts 57 are mounted on" aplate 60 which is bolted to one of the vertical members 9. The driving of the-train' of spool gears is accomplished by means of a sprocket chain 61 which engages a sprocket wheel 62 located on the mam shaft 62.

- The uniform distribution of the tape on the re-windin spools 52 is accomplished by means'of gut cs 63 which are mounted upon the guide frame 64, which is slidably mounted in bearings 65. Rigidly secured to the lower bar 66 of the guide frame is an arm which there is cut an endless right and left cam slot.

ed with a The simultaneous operation of -the rewinding rolls, the drive rolls, the feed rolls,-

and the; wringer'is accomplished by means of the mechanical connections between them. The feed shaft 69 is secured to the main shaft 62 by means of a set screw 70. A gear wheel 71 meshes with the gear wheel 72, which drives a sprocket wheel 62f which in turn operates the re-winding spools by means of a sprocket chain 61. The sprocket wheel 73 is mounted on the shaft of the igearwheel 72, and is connected to operate ;the drive rolls 8 by means of a sprocket fwheel 74, and chain 75. A driving sprocket wheel 76 is connected to operate the shaft ;23 of the wringer rolls 6 by means of a chain 7, lengaging the sprocket wheel 78. Provi- E sion is also made for operating the wringer :rolls 6 and the feed rolls 8 manually by the lformation of a square head on one end of iend of the main drive roll shaft 7 9.

Theconnection of the motor with the main {shaft is' made by means of a worm gear 80 m'ounted to tl llll loose on the main shaft. ;The worm gear is surrounded by a casing ,81, which forms journals 82 for a worm ishaft 83 which is mounted on an extension ,84 of the motor shaft 85. The face of the lWOIIIl gear is provided with two pins 86 which are arranged to engage two pins 87' :mounted on the face of a clutch 88, which is in turn mounted on the main shaft 62 and is prevented from rotation on said shaft by means of a spline 89.

i .An electrlc alarm system is provided which is shown diagrammatically inFig. 1. Contacts adapted to, close the alarm circuit are provided by an insulated block 90, which is adapted to coact with the free end 'ofithe arm'35 in case of the breaking of the tape before it reaches the heating element. The electric alarm is operated by meansof 'a-battery 91, one terminal of which is connected to the insulated contact block 90, the" other terminal beingl connected to the pivot 36which supports t e contact arm 35'. The electric alarm is sounded by including in the circuit the usual electric alarm bell 92.'

In case of'breaking of one or more of the tapes between the feed rolls 8 and the rewinding spools 52, the electrical circuit, inoludin the battery 91, and the bell 92, is

ithe main wringer roll shaft 23 and on onev closed y means of an insulated block 93',-

which coacts with any one of the finger guides 50.

In operatlon, the tape A is unwound from spools suspended in the molstening tank 2,

and is threaded through the machine, as in dicated in Fig.1.

To thread the tape on the machine, the .frame 14 is removed from the moistening tank, and spools 13 are mounted on spoolshafts 13 between the vertical members 15.

" The catch bearings 17 are swung to engage .jsion clip 17 is so placed as to normallyoffer resistance to the rotating of the spool 13. The respective tapes are then drawn through between the vertical rods 19 around the respective idlers 18 through the l :eye 21, over the top of the frame, to the wringer rolls 6. The wringer roll may be 1o manually operated by turning the roll shaft by means of a crank handle, having a square socket to fit the end of said shaft, and is connected; by chain and sprocket mechanism to the main drive shaft 79. From the wringer roll, the tape is pulled over the top edge of the frame, contacting with the frame at 31, from which contact the tape is drawn around its respective roller 34,

located on the tensionframe 32, up to the; guide roll 42. In order to place the tape bethe smoothing.

tween the guide roll 42 and roll 43, the smoothing roll is lifted by means of the handle 45 to a vertical position.

After the tapes are all threaded over the guide roll 42, the smoothing roll is replaced in the horizontalposition. From the smoothing roll, the tape A passes over the heating element, contacting with the curved surface 38. At the end of the curved surao face 38, the tapes ware'held in their respective paths by passingbetween guide pins 47 similar to the guide pins 46, which are placed in advance of the wring-er roll 6. The tape A next passes between guide rods 48, which as give the tape ahalf turn and secure perfect alinement when the tape reaches the drive rolls 8. From the drive rolls 8, the tape is threaded through eyes 49 at the extreme ends of the guide fingers 50. From the to guide fingers 50, the tape passes between distributing guides 63, wh1ch are secured to the guide frame 64. Then the ta e passes directly to the re-winding spoo s 52, to which the end of the-tape is made fast. After the ends of the tapes A have been secured to the re-winding spools 52, the re winding spools are secured -against rotation relative to their respective shafts 53 by turning the wing nuts 55, so as to force the so cone bearings 54 against'the'spools.

The tape havin been threaded through the machlne, the fimounted thereon, is immersedin the tank2, which contains suflicient water to entirely as cover all of the spools. When the frame-14 is lowered into position, the tapes are b threaded between t e guide rods 46 in front of the wringer 6. Then the arm 35 is swung into position so that its forks engage to the tapes A. The heating element is heated by the gas burners 39. The proper temperature of the heating surface 38 is indicated' by the thermometer 38', which is at tached to the heating plate '38. Progressive movement of the tape from the molstening which engages the cam slot on the face ofame 14, with the spools *tank a there-wii1ding mug is produced by starting the motor 12 and sliding the clutch:

88 on the 'main shaft 62, so that the pins '87" engage the pins 86 on the worm gear di- 7 rectly connected to the motor. 79

Since all of the moving parts are mechanically connected to the main shaft 62, as soon.

.as the clutch 88 is placed in operating posi-' tion, the reminding rolls will be rotated, ,taking up thetapeas rapidly asit is delivfl? ered by the drive rolls 8, and the dlstnbuting guides 63 will uniformly distributethe tape to the surface of the re-win'ding spooh 52 through the action of the shoe guide 68 7 8othe-feed roll 69. In case of the breaking of.

any one of the tapes in the passage from the.

original tape spool 13 to the re-winding spool 52, or when the end of, the tape is;

reached, the arm 35 will be released, and the free end of the arm will drop, closing an electric alarm circuit between the pivot 36 and the insulated contact plate 90. In a similar manner, in theabsence of the tape or of tension on the tape between the drive rolls 90 8 and the re-winding spool 52, the. finger guides 50 will drop, maklng contact with the lnsulated stop block 93, thereby closing the electric alarm circuit between the insulated block 93 and the pivot 51. In the event of 95 the breakage of any tape, the electrical alarm is operated,.calling the' attention of the operator, and the machine can be stopped by either stopping the motor 12, or sliding the clutch 88 on the main shaft to throw the clutch pins out of engagement.
