Application filed Becemoer 30, 1914.

To all whom it may concern Be it known that 1, Ear: ST Knssnnn, a citizen of the German Empire, residing at Stuttgart, in the Kingdom of Wurttemberg, Germany, have invented new and useful Improvements in Machines for Marking lVebs of Fabric, Paper, and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for marking webs of fabric, paper, and the like, and the object of the improvements is to provide a machine of this class in which the web is fed by means of two pairs of clamping bars which are reciprocated in line with eachother and in opposite directions toward and away from each other, and which are alternately thrown into clamping engagement with the web, and which are provided with the means for applying the mark to the web, said clamping bars cooperating with web carrier in the form of a band which supports the web substantially over the whole surface thereof which is being engaged by the clamping members, so that no strain is exerted on the web by gravity. Thereby I am enabled to feed vebs of different thickness or elasticity in a uniform way, so that the marks are applied at exactly predetermined distances away from one another.

By means of my improved machine I am enabled to apply to the web marks of any kind, such for example as marks for inclicating the length of the sections of the web, business marks, advertising marks, and the like, and the marks can be applied to the web at any desired distance.

In the preferred form of the machine I prefer to connect the clamping means with the means for supporting the web in such a way, that the feeding of the carrier is effected independently of the carrier itself and in such a way that no strain is exerted on the carrier.

For the purpose of explaining the inven- Patented Jan. 25, 1913.

Referring to the example illustrated in the drawings, my improved machine consists of a pair of lateral frame members 29, 29 which are formed at their upper ends with lateral arms 29 29, and which are suitably braced apart by transverse rods 29. On the tops of the lateral arms brackets 2-3, are secured wiich arovide supports for longitudinal guide rods 13, 13 located one at each side of the machine. On the said guide rods a pair of lower clamping bars 1, 3 are mounted for reciprocation which cotiperate each with an upper clamping bar 2 and i respectively for feeding the web of fabric or the like. The clamping bars 1, 2 and 3, are adapted to be reciprocated on the guide rods 13 in opposite directions and from opposite ends to he middle there of and back again, and such reciprocating movements are imparted to the clamping bars by means of endless chains 9, 10, 11, 12 which are trained on sprocket wheels 5, 6, 7, 8 which are mounted for rotation on vertical shafts 9 12 secured to inner lugs 9", 12 of the side frames 29. As appears more particularly from Fig. 7 the clamping bar 1 is formed at its ends with vertical guide ways 1 on which slides 28, 2-1 are vertically movable. To the said slides shafts or trunnions 21, 22 are secured which carry at their inner ends rollers 81 and 82 respectively which engage longitudinal guide 1 wheels 17 and 18 are secured to or made integral with the beveled gear wheels, and they are adapted to roll on racks so'that their rotary movement is transformed into rectilinear movement of the slides 28 and 2a and the clamping bar 1. This rectilinear movement is transmitted to the clamping bar 8 through the chains 9, 10, 11, 12.

The construction of the said racks will be best understood from an inspection of Fig. 8Q

As shown plates 15 and 16 are secured one to each side of the frame members 29, and the said plates are provided with elongated openings formed at their side walls with internal rack teeth, the plate 15 being provided with upper rack teeth 15 lower rack teeth 15, and lateral rack teeth 15, so that an end less rack is formed which is engaged by the pinion 17. The elongated opening of the plate 16 is formed at its walls with similar internal rack teeth which are not shown in the drawings, the rack teeth of the plate 16 being engaged by the pinion 18. When the bevel gear wheels 19 and 20 are being rotated the gear wheels 17 and 18 roll on the lower lateral and upper parts of the racks, and in order that the rolling movement be free of shocks which might be caused when the gear wheels 17 and 18 pass from the lower parts to the lateral ones, or from the lateral parts to the upper ones, the lateral and upper and lower parts merge into each other through circular portions as will readily be understood from an inspection of Fig. 8. When the gear wheels 17 and 18 pass from the lower parts of the racks through the lateral parts and to the upper ones, the direction of the travel of the clamping bars 1 and 8 is reversed. The lateral portions of the racks are provided in order to make sure that the movement be reversed exactly atthe end of the upper and lower parts of the racks. Preferably. the lateral rectilinear portions are made as short as possible, in order that the gear wheels 17 and 18 pass through the same within a moment, and the movement of the clamping bars and the web of fabric fed thereby is interrupted during as short a period as possible.

In order that the gear wheels 17 and 18 follow their paths along the racks, they are guided by means of the rollers 81 and 82 rolling on the longitudinal grooves of the rails 18 and 14:. While the gearwheels 17' and 18 roll on the racks the rollers 31 and 82 rolling on thegrooves of the rails 18 and 1 1- prevent the same from getting out of engagement with the racks. At the ends of the grooves 18 and 11 of the rails 18 and 1d pins88, 341, 85, and 86 are secured to the latter, and the upper and lower grooves 18 and 141* are connected at their ends by trans- 7 verse grooves 68, 6%, 65, 66.

T 1e clamping bars 1 and 8 are so connected with each other hrough the chains 9, 10,11, 12, that the bar lreciprocates on the left hand portion of the rails 18, 1 1 and the bar 8 on the right hand portion thereof, and that both bars meet at the middleof the said rails.

The upper clamping bars 2 and 1 which cooperate with the bars 1 and 8 for clamping and feeding the web of'fabric or the like are yieldingly connected with the lower bars 1 and 2. As appears more particularly from Figs. 8, 5 and 7, bolts 87 and 88 are secured to the lower clamping bar 1 and pass through bores made in the upper clamping bar 2. Between the heads of the said bolts and the top of the clamping bar 2 springs 87 and clamping pressure on the bar 2 and force the same in yielding contact wih the clamp ing bar 1. In a similar way spring actuated bolts 89 and 40 are secured to the upper clamping bar 1 and pass throughbores made in the bar 8, so that the said clamping bars are yieldingly forced in clamping engagement with each other, as is shown in F igs, l, 5, 6,

operative part of the machine. To prevent,

the band from being shifted laterally longitudinal belts dat of leather or rubber are secured. to the inner surface thereof glusewing, or the like, and the said belts engage in annular grooves of the rolls 45, 16, a7 and 48 and the railsfl, 8.

To release the clamping bars 1, 2 and 8, 1 from the tension which is necessary for carrying the band 14; along, the handguiding roll' ltl is provided with driving means of its own. As shown, on trunnions 16* of the said roll sprocket wheels and 50-ar e loosely mounted which areadapted to be coupled to the roll by means of spring actuated clutch members 57 and 58, the clutch jaws of the parts 19, 57 and 50, 58 being oppositely directed, so that 7 one of the 88 are coiled around the bolts which exert V clutches is operative for rotation of the roll in one direction and the other one for rotation in the opposite direction. 611 trunnions and 56 secured to the plates 15 and 16 sprocket wheels 53 and 5eare loosely mounted, and on the sprocl et wheels 4:9, 53 and 50, 5e chains 51 and respectively are trained, The upper stretch of the chain 52 is secured to the rear end the clamping bar 3, and the lower stretch of the chain 51 is secured to the front end of the clamping bar 3, so that the sprocket wheels 49 and 50 are rotated in opposite direc 'zionsv In the positions of the parts shown in the drawings the gear wheels 1? and 18 move from the left to the rigat, so that the pairs of clamping bars 1, 2 and 3, i move in opposition to each other, as has been indicated in Fi 1 by the arrows. The pair of clamping bars 1, 2 are in clamping engagement with the supporting band a4- and the web of fabric 13 placed thereon, while the clamping bars 3, l are out of clamping engagement. A the gear wheels 17 and 18 roll on the racks 15, 16 the pairs of clamping bars are approached toward each other by means of the chains 9, 1G, 11, 12, so that the web of fabric clamped between the bars 1 and 2 and supported on the band 4A is carried along in the direction of the arrows. In this case the supporting band +1 1 is rolled off by the tension of the chain 51 acting on the guide roller 416 he sprocket wheel 1-9 bein engag mc; 1th the clutch member I so that it is re ated in th direction for unwinding the supporting band. in the meantime the sprocket wheel is rotated 11 the opposite dire on, because the upper stretch of the chain 52 is attached to the and the clutch the sprocket the clutch bar "p ',i 1.1 r 4: wheel oo rme on M16 ams member 58.

no i i when the t on thel on rever own in non-clampl which was in thr wn in clampcge in the operation ormed while the gear 13 more along the vertical of the rack, and the slides 23 wit the guide amping bar 1 septhe and hold the chews in i 1-,. 2 by en- 1 ,io 4,9} mo ng upward fo the cl e bl r 2 rrom in too position i a with their to faces below tae ends of the said bars. Simultaneously spring aetuated lockin bolts 59 and 60 provided in t3 the clamping bar 3 in position I01 locking engagement with the bolts 39 and 40 get in contact with stop lugs 61 and 62 provided on the machine frame so as to be thrown out of locking engagement with he spring actuated bolts 39 and 40, so that the latter throw he clamping bars 3 and i into clamping engagement. While the positions of the clamping bars are being changed the rollers 31 and 32 pass through the transverse grooves 63 and 6a of the guide rails 13 and 14.

After the clamping and releasing operations have thus been reversed, the clamping bars start their movement in the reverse direction, as has been indicated in l ig, 2 by the arrows, the gear wheels 17 and 18 which are being rotated in the same direction as before engaging in the upper s ctions 15 of the racks, so that the pair of bars 1, 2 is moved from the right to the left and, through the chains 9, 10, 11, 12 the pair of clamping bars 3, l from the left to the right. Now the pair of clamping bars 3, a has the function to advance the web of fabric in the direction of the arrows shown in Figs. 1 and 2. The supporting band as is unrolled from the roll 16 by means of the chain 52, the sprocket wheel 50, and the clutch 58.

he movement of the clamping bars away from each other is finished, when the gear wheels 17 and 18 arrive in the opposite vertical parts 15 of the rack, whereupon the rollers 31 and 32 pass through the transverse grooves 65 and 66. Thereby the slides 23 and 2-51 of the clamping bar 1 are pulled downward so as to release the upper clamping bar 2 and permit the same to be forced downward by the springs coiled around the bolts 37 and 38, so that the pair of clamping bars 1 and 2 gets in clamping engagement. N ow rollers 67 provided on the slides 23, 24c engage on the top faces of shoes 68 provided on rocking levergGS located one on each side of the machine frame, as is shown in Figs. 3 and 4. Thereby the rocking levers 69 are rocked with their opposite ends upward, so that shoes 70 provided at the opposite ends shift the bolts 39 and 4:0 upward, which at this moment are in positions for engagement by the shoes. Thereby the bar is lifter from the bar 3. In the uppermost position of the bar a the spring bolts 59, 60 get into locking engagement with the spring bolts 39 and 41 0 and hold the upper bar 4: in position, until the locking bolts are again thrown out of locking position by the stop members 61 and 62, as has been described above The driving mechanism for the gear wheels 17 and 13 is constructed i; the following way: Referring to Figs 3, 5 and 7, the bevel gear wheels 19 and 20 are connected with the wheels 17 and 18 and are mounted therewith on the shafts 21 and 22 respectively secured to the slides 23 and 88 and 89 screwed to the shafts S1.

The bevel gears are in mesh with bevel gear wheels 72 and 7 3 the hubs of which are secured to sleeves 7 1. Through cylindrical bores of the hubs of the bevel gears 7 2 and 7 3 stub shafts 75 and 76 are passed which are formed at their upper ends with transverse eyes 75 and 7 6 by means of which they are suspended from the shafts 21 and v formed on the shafts 75. Thereby the bevel gears are held in their proper positions rela tively to the shafts 21 and 22. To the outer ends of the shafts 21 and 22 sleeves 77 and 78 are secured which hold the eyes 75 and 7 6" in their positions on the shafts 21 and At their lower ends the sleeves 7 1are engaged by shafts 81 which are connected therewith by feathers 80 and slits 79, so that the parts are slidable relatively to each other, while rotation is transmitted from the shafts 81 to the sleeves 71. To the lower ends of the shafts 81 bevel gears 82 and 83 are screwed the hubs of which are embraced by hearing plates 81-, 85 (Fig. 3) which hold the said hubs and bevel gears in the'proper position relatively to bevel gears 86 keyed to a main driving shaft 87. The bevel gears are held in position on the shafts 81 by nuts The bearing plates 8 1 and 85 are rigidly secured by screw bolts nuts 841 and 81 to bear- 7 l tl h ft8 ing panes 90 mountec on 1v s a 7. nine bearing plates 90 are held in position on the shafts 87 by sleeves 91. Power is supplied to the shaft 87 from an electromotor E through gear wheels 92, 93.

While in the foregoing I have described the mechanism for feeding the web of fabric along a plane, 1 shall now describe the mechanism for applying marks to the fabric.

1n the example shown in the figures the pair of clamping bars 1 and 2 carries the mechanism for applying the marks. As appears more particularlyfrom Fig. 9 a rod is slidably mounted on the bar 2 which con sists of a cylindrical part 9% and a flat part 91-. The cylindrical part is guided in a bracket 91 provided 011 the top of the bar 2, and the flat part 9% is guided between a pair of lugs 97 and 98 provided on the bar 2 and preventing rotation of the rod 91.. The rod 9st is adapted to be shiftedin longitudinal direction by means to be described hereafter, and when shifted in forward direction and into the position shown in Fig. 9 in dotted lines, a nose 100 formed at its end is engaged by a. spring actuated pawl 101 which is pivotally mounted on the top side of the bar 2. To the cylindrical part of the rod 9-1 two nuts 95 and 96 are secured, and betweenthe nut 95 and the noses 97 and 98 a'spring 99 is coiled around the rod which tends to shift the same rearward in Fig. 2 and into the position shown in full lines. The nuts 95 and 96 are located on opposite sides of an arm 102 of a slide rod 102 which takes part in the movementsof the rod 94: and is slidably mounted on a plate 103 secured to the bar 2 by screws 104, 105. V

For imparting longitudinal movement to the rod 91 the following mechanism is provided: The rod 94 is formed with rack teeth 9& which are in mesh with the teeth of a pinion 106 mounted on a stub shaft 108 and ri idly connected with a gear 7 wheel 107 secured to the bar2. The pinion106 is rigidly connected with a gear wheel 107 the teeth of which are in mesh with a pinion 109 the hub of which is mounted in a cor responding bore of the bar 2 and held there'- in by a ring 112 secured to the said hub and engaging at the rear of an annular shoulder 112. The pinion 109 is rigidly connected with a crank arm 110 having a. crank pin 111. Through a bore of the hub of the pinion 109 and the crank 110 a stationary stub shaft 113 is passed which is screwed into the bar 1. On the stub shaft 113 a gear wheel 11 1 is mounted for rotation which is formed with an arc shaped slit 115 whichis adapted to be engaged by the crank pin 111 when the bar 2 has been lifted from the bar 1. The stub shaft 118 is provided with two collars 116 and 117 which are adapted to be by the cylindrical end of a screw 11S screwed into the hub of he gear wheel 11% and are adapted to lock the gear wheel 111as against displacement axially of the stub shaft 113. The gear wheel 11% is in engagement with a pinion 119 which is rigidly connected with a gear wheel 120. The pinion 1 9 and the gear wheel 120 are mounted for rotation on a shaft 121 which is screwedinto the bar 1,

and they are looked as against longitudinal travel of the clamping When the latter are moving in the direction towardthe clamping bars 3, 1, has been indicated in Fig. 1, the gear wheel 120 when seen from" above in Fig. 9 rotates in the direction of the hands of a clock, and when the pa rs of clamping bars move in the direction away from each othenas is indicated in Fig.2, the gear wheel 120 rotates in the opposite direction. As the gear wheels 11 1 and 119 Therefore, when moving the pair of y take always part in the movement of the clamping bars and the rotation of the gear wheel 120, while the rod 94 must be at rest when applying the marks to the fabric, the gear wheels 100 and 114: must be temporarlly disconnected. This is done by means the crank 110 and its pin 111 which are adapted to be shifted axially of the gear wheel 1 41 together with the clanriing bar 2. l hile the clamping bars 1 and 2 are in g position, has been shown in L the gear wheels 109 and 11 1 are isconnected and the rod 9% is free to be moved by the spring in the direction of the arrow, as soon as the locking pawl 101 is retracted from the nose 100. This is done when the pawl is engaged by a pin 12 1 secured the plate 15. hen the rod 94 is i N shifted into the position shown in 9 in dotted lines, also the bar 102 is f cm the position shown in dotted 11 d into the position shown in. 1 lines. In order 102 and 'nied on the rod 102 remain in engagement with gear wheels and 126, the rod 102 is guided on 7 28 seen-ed to the plate 103.

1 and 13 l have shown fur- 03, the object of ect the marking t rod 91, and 102. As shown roll 130 is oosely mounted on a stub l olt 129 secured to the plate 103, which roll is adapted to receive a perforated marking web 132 rolled on a sleeve To prevent the sleeve 131 from falling off the bolt 129 a. screw 133 fitted therein which engages with its cylindrical end in an annular groove 134: of the bolt 129. 11s is shown in Fig. 14c, the head of the screw 133 and also that of a screw 1S8, engas es in a slot of the sleeve 131 and locks th eve 131 as against displacement relatively to the roll 130. The marking web 132 is passed over pins 135, 136, 137, and 136 and 'o a drum 139 provided with conical pins 11-0 which engage in holes made in the web of in rking paper and at one side thereof, whereby the marking web is positively driven from the drum. The drum is loosely mounted on a bolt 1 11 which is screwed into the'plate 103. To the hub of the drum 139 ratchet wneel 1 12 is ri idly secured, and at the rer of the said ratchet wheel a dish shaped disk 1 13 is loosely mounted on the bolt 1&1 which is formed at center with an opening and which has p; ing 1 14: wound about its circumference. he spring is connected with one end to the and with its opposite end to a pin secured to the plate 103. @n the front side of the disk 1 13 a pawl 14-6 is pivotally mounted which is adapted to engage in the teeth of the ratchet wheel 1 12. To the rear of the disk a lu 1&7 is soldered which is in contact with a pin 1&8 projecting from the rack 102.

From the drum 139 the marking web is sscd over a pin 1 19 and along a casing inclosing the stamp or punch to a marking stamp 151. The casing 150 is secured to the plate 103 by means of screws 17% and 175. By -ineans of the punch 151 the marks the edge of the punch 151 does not set a, l o

in contact with the web of fabric. To the head of the marking punch screws 153 and are secured which are engaged by a bifurcated lever 155 mounted vith its shaft in a sleeve fitted in a bore of the plate "no. To one end of the shaft a bifurcated crank arni 157 is secured by means of a screw 156. With the rod in the released position shown in the figures in full lines a pin 150 screwed to the rod 94: ngages in the bifurcated part of the crank arm 157. inereby the punch 151 and the striper 152 1 re in the positions shown in the figures. (in. the stern of the striper 152 a coiled spring 160 is located which is disposed within a bore of the punch 151 and has the tendency to retract the striper into the punch 151. In the position of the parts shown in Fig. 13 one of the arms of a lever 161 mounted on the crank arrns 155 has been brought into engagement with a screw 16 Thereby the other arm of the said lever has been brought into engagement with the head of the stem of the striper 152, so that the striper has been shifted out of the punch against the action of the spring 160. The lever 161 is supported on a pivot 163 fitted in the head of the punch 151.

Before a mark is punched from the web a ll-shaped web clamping frame 16 straddling the casing 150 presses the web against the punch casing 150. The web clamping frame is provided with a bore permitting the passage of the punch 151 theretirough, and it provides a matrix for the punch 151. in order that the clamping frame can be retracted from the marking web, as must be done whenever the web is being advancec, the arms of the web clainping' frame 16% are connected with arms of bell crank levers 165, 166 located one at each side of the casing 150, which arnis engage pivots 167 and 166 secured to the clamping frame. The bell crank levers 165, 166 have rocking supports on a pivot 169 secured to the casing 150. Both bell crank levers have exactly the same form and they are formed with elongated holes 170 which are engaged by calns 171 and 17 2 secured to a shaft 173. The shaft 17 3 is mounted in bearings provided on the punch casing 150, and it passes through the plate 103 and carries at its opposite end a disk 176. At the rear of the di 176 a disk 177 is loosely mounted on the,

- and the hub of'the said disk has wheel 126 secured thereto. On the which is located at the rear of a shoulder formed on th disk 176 and is adapted to rotate the disk 176 and the shaft 173 in the direction of the arrow shown in Fig. 11, v. hen the rack 102 is being shifted from its position shown in full lines into the position shown in dotted lines. Simultaneously the pawl 178 is moved into the position shown in dotted lines and it is retracted from the disk 176 by striking a pin 179.

On the shaft 173 a back pressure lever 180 is mounted which carries a wedge 181, which can be set by means of a screw 182. By means of the back pressure lever 180 the clamping frame 161- is released from the shocks which are caused when the pawl 178 is retracted from the disk 17 6, and the disk as and the shaft 173 ai 183 in the direction 0 the arrow shown in Fig. 11. The spring is secured with one end to the shaft 173 and with the other one to a pin secured to the plate 103.

After the mark has been punched from thr wn by a spring thev web, the latter is fed away from the punch casing 150 and supplied to a roll 185 which is mounted on a stub shaft 186 and is held in position by means of a screw 188 engaging in an annular groove 187 of the stub shaft, as is shown in F i g. 12. To a hub of the roll 185 a ratchet wheel 189 is secured, as is shown in Fig. 1 1. The stub shaft 186 is secured to a plate 190 which is and is held in position by means of a screw 191, 192, 193, 19 1-. At the rear of the plate 190 a dish shaped disk is loosely mounted on the stub shaft 186, which has a perforated bottom having a further aperture 196 permitting the passage of the hubs of pawls 197, 198, and a gear wheel 199, which are supported on pivots 200, 201, and 202 respectively. To the bottom of the dish shaped disk 195 a pin 203 is secured which passes rearward and through a slot 2041 of the disk 190. The perforated bottom of the disk 195 is formed with internal teeth over a part of its circumference, and the teeth are in mesh with the pinion 199. Around the disk 195 a spring 205- is coiled which is securedavith one end to the margin of the disk and with the opposite end to the pin 184. The spring tends to rotate the disk in the direction of the arrow shown in Fig. 13. Between the bottom of the disk 195 and the ratchet wheel 189 of the roll 185 a segment 206 is loosely mounted on the pivot bolt 186, and on the said segment pawls 207 and 208 are mounted for engagement with the teeth of the ratchet wheel 189. The pawls 197 and 198 are likewise adapted to engage in the said ratchet wheel. To the hub of the segment 206 a gear wheel 209 is secured which is in engagement with the i 1 '7 a pawl 178 has a rocking support pinion 199. As the spring 205 has the tendency to rotate the disk 195 in the direction of the arrow shown in Fig. 13, the segment which is connected with the disk 195 through the wheels 199 and 209 tends to rotate in the opposite direction. By the engagement of the pawls 207 and 208 in the ratchet wheel 189 the segment is adapted to carry along the roll 185 and to wind the web 132 on a sleeve 131 made from card board or the like. The spring 205 is put under tension by means of a hook 210 se cured to the rod 94, which hook engages the pin 203 when the rod 9% is being released and rotates the disk 195 and the segment 206 into the position shown in Fig. 13 through the intermediary of the gear wheels 199 and 209.

- In the example shown in the drawings tne web of fabric is marked by gluing marks thereto. Therefore the marks which have a suitable gluing substance applied to their rear sides must be moistened prior to being punched from the web. F or this purpose a moistening apparatus is mounted on the bar 2 which will be described hereinafter. On a slide bed 211 which is secured to the bar 2 by means of screws 212 and 213 a slide 214. is mounted which is formed with ears 21o disposed at right angles thereto. To the said ears a valve casing 215 is secured by means of screws 216, 217 and 218. The slide 214 is formed with rack teeth 219 which are in mesh with the teeth of a gear wheel 220 secured to the shaft 220 carrying the gear wheel 125 and guided in a sleeve 221 of the plate 103. Thereby the slide takes part in the movement of the rack 102 and moves always in the direction opposite to that of the rack 102. V

The valve casing 215 consists of two parts which are held together by screws 222, 223,

and 22 1. In cavities of the valve casing there are valve plugs 225 and 226 whlch are connected with crank arms 229 and 230 re- '4' spectively by screws 227 and 228. The shafts 229 and 230 of the said crank arms are passed through bushings 229 and 230 of felt or the like fitted in bores of the side wall of the casing 215, and at their outer ends they carry wings 231 and These wings are acted upon by springs233 and 234 which tend to force the plugs'225 and 226 with their ends into the passages 225 and 226 located in front, of the same so as The passage 225 which tact with the head of the plunger 236. A n

screw 239 connects the head of the plunger 236 with a lever 2&0 which is mounted on the slide 214: at 2411.

To the bar 2 a rubber tube 2&2 is connected which connnunicates at one end with he pipe of the valve casing 215 and at cS opposite end with a metal pipe 243.

1 .1118 latter is connected to the conduit of a retary pump the suction and pressure pipes of which are in communication with a receptacle containing a suitable gluing medium. he r 4y pump 2 11- is driven from the driving shaft 87 through a belt gearing.

Thereby the plunger sucks in the gl e -vhlch has not been f the mouth 215 of nereby prevents the gluem dripping off the mouth of the vlve casing, Before the end of the return move t o the slide 2141 the win 231 encw 250 and opens the passage is located. in front of the valve pl *hile the lever 2 110 engages the so and the plun is withdrawn from the valve casing L 5 further than would be possible, it the spring 1238 alone were provided for this purpose. As the plunger is being moved farther outward, the gluing medium which is being supplied by the rotary pump 2 1% and through the tube 242 is drawn in by suction. If in the next operation the slide 21% is again moved toward the punch casing 150, the valve plug 225 closes at first the passage which is located in front thereof, hereupon the valve plug is retracted from the passage 226 located in front of its end, and simultaneously the phmger forces the gluing medium which has been drawn in by the previous operation and the one which has been newly received is forced by the plunger 236 through the passage of the month 215*"- of ti e valve casing 215 in order to moisten the next mark.

After the mechanism has thus been described in detail 1 shall now describe the operation. As appears from the drawings, the pair of clamping bars 1 and 2 has clamped the web of fabric -13 and carries the same along in the direction of the arrow shown in Fig. 1. 1n the position shown in the figure, the pair of clamping bars 1 and 2 have already passed beyond the pin 12% secured to the plate 15, so that the locking pawl 101 has been retracted from the rod 91-, ano the said rod has been shifted by the pressure of the spring 99 in the direction of the arrow. By reason of this displacement of the rod 9 1 the hook 210 has taken hold of the pin 203 and has rotated the disk 195 into the position shown in Fig. 13. In a similar way the pin 159 secured to the rod and striking on the crank 157 has caused the punching of a mark from the web of marking paper and shifted the punch into the position shown in Fig. 13. Simultaneously with the rod 9% the rack 102 has been moved, so that the pawl 178 has been brought from the position shown in dotted lines into the position snown in full lines. and the pin 118 which is located in front of the lug 1 1? of the disk 113 has moved the said lug and together therewith the dish 143 from the positions shown in dotted lines into the positions 8110\"11 in full ines. Simultaneously, by means of the wheels 125 and 220 the 'alve casing 215 of the moistening apparatus has been shifted toward the marking web 132, as is shown in Fig. 13.

Now the pair of cla oping bars 1 and 2 and the marking apparatus mounted thereon more in the d ection of the arrow shown in 1. until the reversing of the movement is st ed and the parts or in the positions n is the i of the movmnent the par ars is r ed. the bar is ie bal 1. while the pair of cl n; .d is closed As the bar 2 1 n 1116 1 uppermost oosition. i 4 pm 111 wh a so far was out of e igageirent with the end walls of the sht 115 is carried along by the wheel 114, so that by means of the wheels 109, 107, 106, the rod 94 is slowly advanced in the direction of the arrow, until the nose 100 arrives in the position shown in dotted lines and the pawl 101 looks the rod 94 in position. The rod arrives in this position shortly before the clamping bars 1 and 2 must again be closed. When the movement of the rod 94 in the direction of the arrows is started, the pin 159 moves the crank 157 more and more into the position shown in dotted lines, so that the marking punch 151 is retracted into the punch casing 150. reason of the construction of the crank 157, j the end of one third of the whole path of the pin 159 the punch has been fully retracted into the casing 150 and is stopped therein. Simultaneously the pin 148 of the rack 102 moves together with the rod 94, so that the disk 143 can be rotated by the spring 144 in clockwise direction in Fig. 13. Thereby the pawl 146 of the disk 143 is gradually brought into engagement with a tooth of the ratchet wheel 142 of the drum 139, so th t it can rotate the said drum. lhe rotation isstarted shortly after the marking punch has been retracted into the casing 150.

But as the pawl 146 approaches a tooth of the ratchet wheel 142, also the pawl 178 and the disk 147 are moving into the position shown in dotted lines because the rack 102 takes part in the movement of the rod 94. Thereby tne shaft 173 is rotated in the direction of the arrow shown in Fig. 11, so that the web clamping frame 164 is retracted from the punch casing an amount which corresponds to the eccentricity of the cam 171. When the pawl 146 engages a tooth of the ratchet wheel 142 the drum 139 is r0- tated by the spring 141 acting on the disk 143 in clockwise direction in Fig. 13, so that the conical pins 1 0 of the drum 139 which engage in the perforations of the web of marking paper 132 take the web from the roll 130. while the rol. 185 which is acted upon by the spring 205, the pawls 207 and 208 and the ratchet wheel 1 9 takes up so much of the web as is supplied by the drum 139. As at the beginning of the movement of the web the clamping frame 164 had alrea y been slightly retracted from the punch casing by the cams 171 and 172 and the bell crank levers 165, 166, the winding and unwinding of the web coincide. Thereby strains on the markin web are prevented and a precise operation is assured. A period of the nnrolling of the marking band 132 is completed,- when the lug 147 of the disk 143 shown in Fi s. 11 and 13 is in contact with the screw 254 secured to the plate 103 and is looked as against tli'urther movement. \Vhen this is the case, the shank of the pawl 178 engages the pin 179 shown in Fig. 11 in order to retract the other arm from the disk 176, whereupon the shaft 173 is thrown back into slide 214. The operation of the inner parts of the valve casing have already been described.

The pin 138 is mounted on an arm 256 which has a rocking support on a pivot 255. Within a bore. of the pin 138 there is alocking pin 257 which is pressed by a spring 258 into a bore of the plate 103. In order that the sets of marks printed on the web 132 can be set on the desired mark when stopping the machine, I preferto construct the apparatus in such a way that the marking web can be removed from the drum 139. For this purpose the locking pin 257 is retracted from the plate 103 by means of a button 259 and against the tension of the spring 258, and the pin 138 and the arm 256 are brought into the position shown in Fig. 13 in dotted lines. After the pair of clamping bars 1 and 2 has again been closed, the gearing shown in Fig. 10 has again assumed the position shown in the figure, and after the rod 94 has been released from the pawl 101 a new mark is glued on the web of fabric in the same way as has been described.
