Docket M~340 position with respect to the print head. U.S. patent to Paul H. Hamisch, Sr.~ No. 3,440,123, granted April 22, 1969 discloses a cam-controlled inker.
The invention provides an improved mechanism for adjusting the relative positions of the ratchet wheel and the feed wheel to vary the registration of the labels with respect to the delaminating means and to the printing means.
This mechanism includes a paix of clutch members which can be shifted apart and rstated relati~e to each other to change the adjustment between the eed and ratchet wheels. The user can make the adjustment by manually driving the feed wheel when the clutch members have been shiEted axially out of clutching engagement with respect to each othex. More specifically, there is a drive connect:ion between one clutch member and the feed wheel which prevents relative rotation between that one clutch member and the ~eed wheel but allows relative shifting movement between that clutch member and the feed wheel. A spring normally holds that clutch member and the other clutch member in clut~hing engagement with each other. The other clutch member is coupled to the ra~chet wheel. The ratchet wheel is mounted by one side of the subframe and the feed wheel is mounted by the other side o the subframe. The subframe is aisposed in the pace within the frame. The frame mounts a shat and the shaft mounts a movable section or cover which is movable between closed and open positions, an applicator roll, and a portion of an inking mechanism. The inking mechanism is simple in construc-tion and easy to assemble, but the inking mechanism will stay in its assembled position e~en through the labeler is dropped on the floor. The inking mechanism includes a pivotally Docke~ M-340 mounted carrier mounted on the cover and a leaf spring con-nected to the shaft and to the carrier. The carrier mounts a roller which is urged against a cam on the print head by the leaf spring. The print head preferably has two lines of printing members for printing two lines of ~ata. A hold-down device is used to hold a label and the underlying supporting mat~rial web down so that there is no gap between the web and the platen. This feature is conducive to quality printing because the print need not move the label and ~he web toward the platen and because if it can be assured that the web lies against the platen, then the distance ~etween the print head in the home or rest position and the platen can be kept to a minimum. It is pr~f~rred that a die roll be used to urge the supporting material web against the toothed feed wheel . In addition, the die roll is spring-urged against the web to accommodate for manufacturing variations in the labeler. The die roll is carried by a holder which is nested i~ the subframe and which includes a pair of leaf springs. Thus, adequate mating cooperation between the die and feed wheels is assured. A leaf spring is disposed in cooperation with the web where it is fir~t paid out a~ the label rollO The leaf spring has a mou~ting portion keyed to the subframe.
Th~ leaf spring is conducive to the gradual paying out of the web from the labeL roll. The leaf spxi~g and its mounting portion are comprised of one-piece molded plastics material.
There is a brak~ which acts on the composite la~el web between the place where the compo~ite web is paid out of the label roll and the plat~n. The brake includes a roll which is Docket M-340 loosely mounted in the subframe and the print haad carrier leaf springs which contact a brake roll at spaced-apart locations. The use of such separate leaf springs is con-ducive to effective braking action against the composite web in spite of manufacturing variatio~s.

Description of the Preferred Embodiment Referri~g initially to FIGURE 1, there is shown a label printing and applying apparatus or labeler generally 30indicated at 30 having a frame or body genexally indicated at 31 which includes a frame section or body section 32 and a ~rame section or body section 33a The ~r~me section 32 is S
Doc~et M-340 ~ ~2 5 ~6 shown to ha~e tubular posts or shafts 34', 35 9 36, 37 and 38 and the body section 33 is shown to have generally tubular aligned p~sts 34, 35', 367, 37' and 38'~ 5crews 39 are received in the posts 34', 35, 36, 38 and 39 and are threadably received in respective posts 34, 35', 36' and 38'. The frame sections 32 and 33 are mates to each other and are substantially mirror-images o each other.
A sub~rame generally indicated at 40 is shown to include subframe sections 41 and 42. The subframe section 41 is shown to have male projections 43 received in and held in a snap-fit manner in apertures 44. With reference also to FIGURES 4 and 5, the subframe section~ 41 and 42 have res pective ball tracks 45 and 46 for receiving respec~ive xolling-co~tact bearing members specifically ball-bearing strips 47 and 48. The subfxam~ sections 41 and 42 have respective guideways 49 and S0 and 49i and 50 ' . The subframe sections 41 and 42 have respective posts 51 and 52 and 51' and 52 ' for receiving respective ~ubular rollers 53 and 54. The posts 51 and 51' rotatably mount the tubular roller 53 and ~h~ posts 52 and 52' ro~ata}:)ly mourl~ the tubular roller 54.
The subframe sections 41 and 42 have respective round holes 55 and 56 for rotatably mounting a feed wheel assem~ly generally indicated at 570 The subframe sections 41 and 42 have res-pective non-circular, specifically dove-tail, recesses 58 and 58' for receiving a holder 59. The holder 59 is of one-piece molded plastics construction and includes a pair of lea springs or spring fin~ers 60 and 61 having a pair of res-pective sockets 62 a~d 63. The sockets are prefarably open-sided and preferably extend for more than 180 but substantially Docket ~340 ~ ~ ~ 5~
less than 350 so as to receive respective stub ends 64 and 65 of a die roller 66. The die roller 66 has a pair of grooves 67 that correspond in contour and alignment to teeth 68 of toothed feed wheel 69 of the assembly 57. The teeth 68 are staggered and axe disposed in two annular rows. A guide plate 70 which is disposed between the rows of teeth 68 has oppositely extending posts 71. The posts are received in h~les 72 and 73 of the respective subframe sections 41 and 42 to confine the supparting material we~ S of the composite web C in proxLmity to the surface of the feed wheel 69~ The subframe sections 41 and 42 ha~e respective non-circular recesses 74 and 74' for keying end portions of a non-circular post 75 of a latch 76. A bar 76" is connected to the post 75 by a leaf spxing 77. The bar 76" has a pair of manually engageable projections 78 and 79 which extend through res-pective openings ao and 80' in sub~rame sections 40 and 41and through respective openings 81 and 81' in the frame se~tions 32 and 33. Shields 82 and 83 are disposed inbound of the projections 78 and 79. The shield 82 is disposed between the ~rame section 32 and the subrame section 41 and the shield B3 is disposed between the frame section 33 and the subframe section 42. ~he shields 82 and 83 serve to keep dust out of the inside of the labeler 30. The subframe sec io~s 41 and 42 have elongated recesses 84 and 84'.
Marginal side portions of a platen 85 are received in the r~spective recesses 84 and 84' and marginal ends oE a de-laminator, specifically a peel roller 86, are received in the same elongated recesses 84 and 84'~ The peel roller 86 is in direct contact with shoulders S7 at the ends of the marginal Docket M-340 ~ ~ 2 5`~ ~
sides of the platen 85. The shoulders B7 define an end edge of the platen 85. There is a minimum of friction between the shoulders 87 and the peel roller 86 because o~ minimal contact.
In addition, any non linearity of the peel roller 86 will have Little or no effect because only the end portions of the peel roller 86 are contacted by the shoulders 870 It is apparent that both the platen 85 and the peel roller 86 are captive in the same respecti~e recesses 84 and 84'. The guideways 49 and 49' are fo~med in part by guides 8B and 8~.
Spaced from the respective guides 88 and 89 are projections 90 and 91. A hsld down and guide member generally indicated at 92 i5 shown to have a hold-down or guide member 93 which is disposed in overlying relationship with respect to the platen 85 and a direction-changing gui.de member 94. A mounting m~mber 91' is interlocked between guide 88 and projection 90 and between the guide 89 and the projection 91 as shown in FIGURES 1 and 20. In addition, the subframe sections 41 and 42 have posts 95 and 95' received in a hole 96 in the member 94. The member 94 has a plurality of ridges 97 and inter-vening grooves 98 which ext~nd i~ the direc~ion of label travel shown ~y phantom lines PL in FIGURE 20~
The subframe sections 41 and 42 have respective retaining recesses 99 and 99' ~or receiving stub ends 100 and 10 of a brake roller 102 of a brake 103. The roller 102 is shown to have annular grooves 104 for receiving spaced~apart 0-rings 104~o A one-piece resilient device ge~erally indicated at 105 includes a leaf spring or spring finger 106 which is shown to be curved and which is integrally connected to a moun~ing portion 107~ The subframe sections 41 and 42 have Doc~et M-340 ~ 5-~3~
respective recesses 1~8 and 108' into which marginal sides of the mounting portion 107 are received. The resilient device 105 is shown to be disposed in ov~rlying relationship with respect to label roll R adjacent the place where the composite we~ C is paid out. The composite web C passes over the resilient device 105 and from there between the roller 102 and brake surfaces 109 and 109'. The brake 103 also includes a plurality of separate spaced-apart leaf springs 103', ~pecifically ~wo, which ar~ in contact wi~h the O-rings lQ4' of the rollex 102 at spaced apart locations. The use of at least two such springs 103' facilitates reliabLe braking in spite of manufacturing variation~.
The frame 31 has a handle generally indicated at 110 : and includes handle portions 111 and 112. The posts 37 and 37' are disposed at the outer end portion of the handle 110.
A manually operable ac~uator generally indicated at 113 is sh~wn to include a lever 114 having a hole 115. The posts 37 and 37' are received in opposite ends of the hole 115 to pivotally mount the actuator 113. The actuator 113 is shown to includa a pair of spaced-apart gear sections or segmental gears 116 and 1170 The gear sections 116 and 117 mesh with respective gears 118 and 11~ rotatably mounted on an axis A'.
A print head generally indicated at 120 includes a pair of racks or gear sections 121 and 122 which mesh with respecti~e gears ~5 118 and 119. A resilient device generally indicated at 123 bears against ~he handle 110 and 110' and against the inside of the actuator 113 to urge the a~tuator 113', the feed assembly 57 and the print head 120 to their initial or rest positions as shown in FIG~RE 3. The resilient device 123 is shown to include a compression spri~g 124 which urges sections 125 and 126 to extended positions with respect to each other.
Docket M-340 The print head 120 is shown to have two sets of ~ pri.nting members 127 and 128 (FIGURES 1, 3 and 6) for printing ; two lines of data on a label L. The lin s are printed in fields F and F' disposed on opposite sides of the hcld~down member 93. Each line of printing members 127 and 128 has selectively manually settable selectors 129 and 130 so that each line can print the selected data on the label h. The print head 120 also has a pair of tracks 131 and 132 co-operable with respective tracks 45 and 46 of respec~ive subframe sections 41 and 42. The ball hearing strip 47 is in rolling contact with and between the tracks 131 and 45 and the ball bearing strip 48 is in rolling contact with and between the tracks 46 and 132. Accordingly, the print head 120 is mounted for movement into and out of cooperation with the platen 85. The racks or gear sections 121 and 122 are shown to be straight as are the tracks 45, 46, 131 and 132 so that the print head 120 moves in a straight line as is pxeferred.
With re~erence to FIGURES 14 and 15, the eed assem~ly 57 is shown to include the feed wheel 69 and a drive wheel, specifically ratchet wheel 133 having teeth 133' dîsposed in an annular arrangement. The feed wheel 69 and the ratchet wheel 133 are shown to be selectively movable with resp~ct ~o each other. The feed wheel 69 is shown to have an annular rim 134 which is connected to a tubular hub portion or pr~iection 135 by a web 136. The tubular portion 135 has an open end 137 and a closed end portion 138. The tubular portion 135 is shown to be rotatably mounted in an annular hole 139 in tha subframe section 41. A projection or retainex 140 joined to the end portlon 138 extends in the axial direction. The ratchet wheel 133 includes a plurality, specifically three, spring fingers 142 having respective . ~
f~5~ ~
Docket M~340 projections or teeth 143. The spring fingers 142 extend through elongated slots or holes 144 in the web 136. When the ratchet wheel 133 is assembled onto the fe~d wheel 69, the projections Lnitially cam the spring fingers 14~ inwardly and as the projections 143 pass through the holes 144, they snap radially outwardly so that the ratchet wheel 133 is coupled in a~sembled relationship to the feed wheel 69 for limited rotational movement. The ratchet wheel 133 is therefore adjustable to a limited extent as limited by the leng~h of the holes 144. The ratchet wheel 133 has a clutch member 145 with an inner surface beveled with respect to axis A' which is provided with a plurality of small closely spaced teeth 146~ A clutch member generally indicated at 147 is shown to have a plurality of mating l:eeth 148 disposed on a bevel for cooperation with the teeth 146 of the clutch member 145. The clutch member 147 has tubu:Lar portions 149 and 150 which extend in opposi~e dir~ctions. The tu~ular portion 149 has a closed end portion 150' with a coi~ slot 151. A
three-lohed ~eat 152 is joined to the end portion 150'. The outer surface of the tubular portion 150 is splined, having what is illustrated as being three splines 153 which are received in a splined hole 154 in the tubular portion 135.
The splined hole has spline grooves 1S5. Accordingly, the clutch member 147 is keyed against rotation with respect to the feed wheel 69 but is slidable axially with respect $o the feed wheel 69. The connection between the clutch member 147 and the feed wheel 69 is considered to be a splined connection.
A compression spring 156, received within the tubular portions 135, 149 and 150, bears at its opposite ends against the end por$ion 138 and the seat 152. The projec~ion 140 ser~es to locate and retain the spring 156 approximately axially disposed within the feed wheel 69. The position of the clutch members 145 and 147 relative to each other can be varied by the user //
Do~ket M-340 ~ ~ ~ 5 ~ ~
by simply inserting a coin into the slot 151 and exerting an inward force to compress the spring 156, and as goon as the teeth 146 and 148 of the respecti~e clutch me~bers 145 and 147 are ou~ of clutching engagement, the user can rotate S the tubular portion 149 and hence the clutch member 147 and move it to a different selected position with respect to the clutch member 145r Rotation of the clutch member 147 causes simultaneous rotation of the feed wheel 69 because of the splined connection. As soon as the user releases ~he force on the end portion 150', the spring 156 returns the clutch member 147 into clutching e~gagement with ~he clutch member 145.
The ~ear 118 is shown to be rotatably mounted on the projection 135 between the frame section 32 and the subframe section 41. The frame section 32 has an annular boss 157 which is shown to be out of contact wi~h the tubular portion 135 bu~ in contact with the gear 118. Accordingly, the gear 118 is captive between the subframe section 41 and the bos~ 157. Th~ gear 119 includes an annular rim 158 with teeth 159 at its peripheryO A web 160 is joined to one side of ~he rim 158 and to a tubular hub portion 161. The hub portion 161 is rotatably mounted o~ the tubular portion 149.
The weh 160 abuts the texminal end 162 o~ the ratche~ wheel 133 and the tubular portion 161 abuts the end o a~ a~nular flange 163 of the frame section 33. Neither the frame section 33 nor its flange 163 contacts the tubular portion 149. Accordingly, the gear 119 is held captive between the ratchet wheel 133 and the flange 163~ It is apparent that the eed assembly 57 is mounted to the subframe 40 which in turn is mounted by th~
frame 31. The adjustment is made from only one side of the Coc~et M~3~0 frame 31 without tne need to shift the f~ed or drive wheels relative to each other. The gear 119 carries a pawl unit generally indicated at 164. The web 160 has a hole or aperture 165. Th~ pawl unit 164 has an integrally formed snap pro~
jection generally indicated at 166 which includes a split pivot or post 167 and projections 168 with beveled cam faces 169. In the position shown in FIGURE 17, the pivot 167 rotatably mounts the pawl unit 164 to the gear 119 and the projections 168 prPvent the pawl unit from being separated rom the gear 119. The cam faces 169 facilitate connecting the pawl unit 164 to the gear 119. In assemblins the pawl unit 164 onto the gear 119, the cam faces 169 are inserted into the hole 165, and by pushing the pawl 164 further into the space within the rim 158, the pawl 164 is coupled for pivotal movement as shown in FIG~RE 17. The pawl unit 164 includes a pawl 16~' having an integral projection or post 170 which can move to a limited extent in a slot 171. The projection 170 can cooperate with a stop face 172 to limit the travel of the pawl 164'. Without a means to limit the pivotal movement of ~he pawl 164' it would be more difficult to assemhle th~ pawl unit 164 with the ratchet wheel 133 because the pawl unit 164 could assume any of a wide variet~ of positions. Once th~ pawl unit 164 is assembled into coopera-tive re~ationship with respect to ~he ratchet wheel 133, the ratchet wheel 133 holds the pawl unit 164 in a position in which the projection 170 is out of contact with the stop face - 172. However, i the gear is disassembled so that the pawl 164 is moved out of contact with the ratchet wheel 133, the stop face 172 again cooperates witn the post 170. Formed integrally with the pawl 164' is a leaf spring or spring finger 173~ The leaf spring 173 is connected to the pawl 164' adjacent the pawl tooth 174 and the other end portion ~ ~ ~ 5~3 Docket M~340 of the leaf spring 173 contacts the underside of the rim 158.
The spring 173 urges the pawl tooth 174 into the path of the teeth 133'~ It is seen that the pawl unit 164 is disposed almost entir21y within the space defined by the rim 158.
When the user actuates the actuator 113, the gear segments 116 and 117 rotate gears 118 and 119 which move the print head 120 into printing cooperation with the plat~n 85, and the pawl tooth 174 moves into position to cooperate with the next tooth 133' on the ratchet wheel 133~ When the user releases the actuator 113 the resilient device 123 urges the actuator clockwise as viewed in FIGURE 3 to return the print head 120 to its initial position shown in FIGURE 3 and to dri~e the pawl 164' to advance the ratchet wheel 113 and hence the feed wheel 69.
~ith re~erence ~specially to FIGURES 1, 22 and 23, the label roll R is shown to be mounted for rotation on hub members 17S and ~76. The hub members 175 and 176 are mounted on leaf springs 41' and 42' formed integrally with subframe sections 41 and 42. The hub members 175 and 176 are identical.
Hence, only the hub member 175 will be discussed in detail.
Th~ hub member 175 is generally disc-shaped and has an annular hole 177. The leaf springs 41' has an annular flange 178 received in the hole 177 for rotatably mounting the hub member 175. The hub mem~er 175 is retained on the flange 178 ; 25 by a retainer generally indicated at 179. The retainer includes an annular disc-shaped portion 180 and a split shaft or post 181 ha~ing a pair of projections 182. The shaft 181 can be inserted through a hole 183 to ~he position shown in FIGURE 22 and the projections 182 hold the retainer 179 in the assembled position. A pair of identical discs or side plates 184 and 185 ar~ used to support the sides of the roll 5.`~
Docket M-340 R ~o that the roll R does not telescope. The discs 184 and 185 can be assembled onto the appaxatus even after the retainers 179 are in place. The disc 185, for example, has a pair of holes 186 and 187 which communicate with each other at a gap 188~ The gap 18a is defined by projections 189. The hole 186 extends through more than 180 but substantially less than 360. The hole 187 is at least slightly larger in diameter than the outsida diameter of the hub member 175.
The hub member 175 can be inserted through the hole 187 and ~hereupon the disc 184 can be shif~ed until a boss 190 on the hub member 175 deflects the projection 189 and is received in the hole 1860 The disc 184 is composed of a resilient material, preferably a thin sheet of transparent plastics material. The disc 184 can be assembled onto ~he apparatus after the hub member 185 and the retainer 179 are in their assembled position, even though the outer periphery of the disc 134 is continuous.
With reference to FIGURES 1, 3, and 6 through 9, ther~ is shown a movable bod~ section or cover generally îndicatçd at 191 for mounting an inking mechanism generally indicated at 192. The cover 191 is pi~rotally mounted on the posts or shafts 34 and 34'. The post 34 together with the post 34' can be considered to be a post or shaft. The cover 191 is a pair of spaced side walls 193 and 194 joined by a panel 195. The section 191 has a pair o spaced apart arms 196 and 197 which are bifurcated and which have snap soc~ets 198 and 199. The snap sockets 198 and 199 have aligned sockets 200 which are annular in configuration and which extend through more than 180 but substantially less than 360 as shown. The sockets 200 are axially aligned and can receive the respec~ive posts 34 and 34'~ It Docket ~-3~0 ~ ~ 5 '~
is apparent that the cover 191 can move between a normally closed position shown in FIGURE 3 and an open position shown in FIGURE 6. The saction 191 can be easily assembled onto the posts 34 and 34' and the user can remove the entire cover 191 and replace the entire inking mecha~ism, if desired. The panel 195 has a pair of slots or cutouts 201 and 202 to enablP the knobs 129 and 130, which are part of the print head 120, to move as the print head 120 moves between the initial or rest position shown in FIGURE 3 and the printing position in which the print head 120 cooperates with the platen 85. The cover 191 can be readily latched in the closed po~ition by latch assembly 76. The assembly 76 is formed in part by projections 204 on ~he cover 191 which have respective cam fac s 205 which terminate at shoulders 206.
The assembly 76 is also formed in part by the latch 76'.
When the cover 191 is moved to the closed position, the cam fàces 205 contact cam face 207 on the bar 76" thereby causing the leaf spring 77 to bend as the bar 76 n mDves generally to the right as shown in FIGURE 3. When the shoulders 206 have cleared the cam face 207 they move into underlying relation-ship with respect to the bar 76" and the leaf spring 77 returns the bar 76" to the position shown in FIGURE 3. The cover 191 is now latched in the closed position. To unlatch ~he latch assembly 76, the user manually engage~ the projections 78 and 79 and moves them rearwardly away from the front o~
the apparatus 30. When the shoulders 206 are clear of the bar 76" the cover 191 can be pi~oted to the open position.
The cover 191 has a pair of dove-tail slots 208 and 209. The slots 208 and 209 can slidably receive mating dove-tail bearing blocks 210 and 211. The bearing bloc~s have respective aligned holes 212 and 2130 When the blocks 210 and 211 are slid into their respective slots 208 and 209 shallow projections 214 and 21S respectively project slightly 1~ .
Docket i~ 3 4 0 into the respective holes 212 and 213. There is enough resiliency in the materials of which the cover 191 and the bearing bloclcs 210 and 211 are composed o let the bearing blocks 210 and 211 slide into place to a position in which the projections 214 and 215 extend into respective holes 212 and 213. .~ inker body or carrier genexally indicated at 216 and shown in considerable detail in FIGURES 10 and 11 has a pair of side members 217 and 218 and a pair of transve~se members 219 and 220~ Arms 221 and 222 are connected to the respective side members 217 and 218. The arms 221 and 222 have respective aligned holes 223 and 224 for receiving respecti~e stub ends 225 and 226 of ink roller 227. The side members are roughened as indicated at 228 and 229. When it is desired to remove the ink roller 227 the side members 217 and 218 are grasped by and between the thumb and index fingers at the roughening 228 and 229 and squee~ed so that the arms 221 and 222 spread apart. The stub en.ds 225 and 226 will ac~ordingly fall out of the respective holes 223 and 224 and a new ink roller 227 can be mounted to the arms 221 and 222 ~y simply squeezing the side members 217 and 218 to spread the arms 221 and 222 to receive the stu~ ends 225 and 226.
The side members 217 and 218 diverge outwardly and have outwardly extending aligned mounting portions 230 and 231, on arms 230' and 231', received in the holes 212 and 2130 The mounting portions 230 and 231 are received in the res-pective holes 212 and 213 of bearing blocks 210 and 211 while the bearing blocks 210 and 211 are slid into slots 208 and 209. Thereafter the carrier 216 is swung into the position shown in FIGURE 3. In this position the arm 230' is disposed for movement between the surface 208' and interference member 201' on the panel 195 and the arm Z31~ is disposed for movement between the surface 209' and interference member 20Z' on the ~ocket M-340 ~25 `~
panel 195 so that the carrier 216 cannot be disconnected from the cover section, as when the labeler 30 is dropped~ With reference to FIGURES 1 and 3 r a spring member generally indicated at 232 includes a leaf spring or spring finger 233, S a transverse connector or m~mber 234 disposed at one end portion of the leaf spring 233, a mounting portion 235 disposed at the other end portion o the leaf spring 233, and another mounting portion 236. The mounting portion 236 is bifurcated and receives an end por~ion of the panel 195. The mounting portion 235 has an elongated slot 237 which receives the post 34 ~o provide a pin-and-slot connection. The mounting portion 235 is disposed between rolls 238 and 239 of an applicator roll 240. As best shown in FIGURE 12, the rolls 238 and 239 straddle the mounting portion 235 and the arms 196 and 197 straddle the roLls 238 and 239 and the mounting portion 235.
The transverse member 234 is received in aligned elongated holes 241 and 242 of a pin-and-slot connection. The transverse member 234 has opp~si~ely extending tran~verse por~ions 243 and 244~ The transverse portion 243 extends into the hale 241 and the ~ransverse portion 244 extends into the hole 242.
~he transverse portion 243, for example, can be inser~ed into the hole 241 while the transverse member 234 is canted with resp~ct to the axis of the holes 241 and 242 and moved into posi ion and thereafter the other transverse portion 234 is moved into alignment with the hole 242~ When the transverse portion~ 243 and 244 are received in respective holes 241 and 242, the spriny 232 can be brought to its normal position in which the sides o the spring 232 are disposed between opposed shoulders 245 and 246 which limit the lateral movement o the transverse member 234. The transverse portions 243 and 244 Docket M-340 are long enough to prevent them from coming out of the respective holes 241 and 242 when the shoulders 245 and 246 cooperate with the sides of the spring 232.
In the initial or rest position of the print head 12U, the spring member 232 urges the carrier 216 to the solid line position shown in FIGURE 3. The carrier 216 has a pair o spaced-apart snap sockets 247 and 248 (FIGURES 10 and 11) having aligned openings 249 and 250~ Stub ends 251 and 252 ~FIGURE 1) of a roller 253 are received in respective openings 249 and 250. The openings 249 and 250 extend through moxe than 180 but substantially less than 360 so that the stub ends 251 and 252 can be snapped into them. The print head 120 carries a c~m ganerally indicated at 254 with a dwell portion 255, a relatively steep ramp 256, and another dwell portion 257. The ink roller 227 is shown to be spaced from ~he print head 120 in FIGURE 3, when the roller 253 bears against the dwell portion 255. When the print head 120 moves toward the inX roller 227, the endmost printing me~bers 127 and 128 con~act the ink roller 227. About that time, with continued movement of the print head 120, the roller 253 rolls in contact with the ramp 256 to pivot the carrier 216 clockwise as viewed in FIGURE 3. r.~hen the prin~ head 120 is in printing cooperation with the label L on the platen 85, the carrier 216 and the ink roller 227 which it carries are in the position indicated by phantom lines PL'. When the print head 120 is in printing cooperation with the label L, the roller 253 is in cvntact with the dwell portion 257. As the print head 120 is returned to its rest or initial position~
the roller 253 moves out of contact with the dwell portion 257, thereafter the roller 253 rolls along the ramp 256, and thereafter the roller 253 rolls onto the dwell portion 255 ~oGket M-340 until the caxrier 216 and its roller 227 are returned to ~he initial position. Because the carrier 216 moves on fixed pivots, a lost-motion connection is provided by the elongated holes 241 and 242 and a lost-motion connection is also provided by enlarged hole 237 in the mounting portion 235.
In operation, a label roll R is loaded onto the hub members 175 and 176 between the discs 184 and 185. The roll R consists of the composite web C composed o a web of supporting material S to which the labels L are releasa~ly . adhered by pressure sensitive adhesive A. The leading marginal end of the composite web C is passed over the resilient device 105, and between the brake roller 102 and the surfaces 109 and 109'. It is preferred to squeeæe the actuator 113 slightly while the leading marginal end is being threaded through the labeler so that the print head 120 is moved away from the initial position to release the brake 102 and so that the brake roller 102 doe~; not exert a braking force on the composite web C. The leadi~g end portion of the composite web C is passed alons the guideway provided by ~;
~ guides 49 and 49'. The composite web C then passes out o~
the front of the apparatus adjacent the roller 54 and thereupon the u~er inserts the composite web C between the platen 85 and the hold-down member 93. The guide por~ion 94 guides the composite web out of the apparatus to a position where it ca~
be grasped by the user who will pull on the composite web C
to draw several additional inches off the roll R. The com-posite web C is thereupon passed around the roller 53, and with the actuator 113 preferably in the fully squeezed or fully op~rated position, the leading end of the composite web C
Docket M- 340 is ~nserted between the die roller 67 and the feed wheel 69.
T~hen the actautor 113 is released, the teeth b8 break through a f rangible portion FS on the supporting material web S
and the rPlated frangible portion FL of the label material L.
Repeated actuation of the actuator 113 will cause any slack to be taken out of the web S and thereupon labels h will be dispe~sed int~ label applying relationship with the applicator 240 as shown ~n FI~URE 3. In this position the trailing ; marginal end of the leading label L is still adhered to the web S. When the user appli~s the label L~ the label L being applied is pulled from the web S. The brake 103 is effective to prevent the composite web C from being paid out of the roll R during application o a label L and an anti-backup pawl 258 ~FIG~RE 1) which cooperates with the ratchet wheel 113 obviates loss of tension in the wab S.
When it is desired to replac~ an ink roller 227, the user pulls on the knobs 78 and 79 to move the bar 76"
away from the shoulders 206 on the cover section 191. The user can thereupon pivot the cover section 191 to ~he ope~
position shown in FIG~RE 6. By squeezing the side mem~ers 228 and 229, the spe~t ink roller falls out of the holes 223 and 224, A new i~k roller can be inserted by squeezing ~he side members 228 and 229 so that the holes 223 and 224 can r~ceive the stub ends 225 and 226 of a fresh ink rollex. Thereupon the user xeturns the cover section 191 to the position shown in FIGU~E 13. The cams or cam faces 205 on the cover cooperate ~;
with the cam face 207 of the bar 76", thereby de1ecting the leaf spring 227 until the cover section 191 is latched in the position shown in FIGURE 3.

The invention provides an improved mechanism for adjusting the relative positions of the ratchet wheel and the feed wheel to vary the registration of the labels with respect to the delaminating means and to the printing means.
This mechanism includes a paix of clutch members which can be shifted apart and rstated relati~e to each other to change the adjustment between the eed and ratchet wheels. The user can make the adjustment by manually driving the feed wheel when the clutch members have been shiEted axially out of clutching engagement with respect to each othex. More specifically, there is a drive connect:ion between one clutch member and the feed wheel which prevents relative rotation between that one clutch member and the ~eed wheel but allows relative shifting movement between that clutch member and the feed wheel. A spring normally holds that clutch member and the other clutch member in clut~hing engagement with each other. The other clutch member is coupled to the ra~chet wheel. The ratchet wheel is mounted by one side of the subframe and the feed wheel is mounted by the other side o the subframe. The subframe is aisposed in the pace within the frame. The frame mounts a shat and the shaft mounts a movable section or cover which is movable between closed and open positions, an applicator roll, and a portion of an inking mechanism. The inking mechanism is simple in construc-tion and easy to assemble, but the inking mechanism will stay in its assembled position e~en through the labeler is dropped on the floor. The inking mechanism includes a pivotally Docke~ M-340 mounted carrier mounted on the cover and a leaf spring con-nected to the shaft and to the carrier. The carrier mounts a roller which is urged against a cam on the print head by the leaf spring. The print head preferably has two lines of printing members for printing two lines of ~ata. A hold-down device is used to hold a label and the underlying supporting mat~rial web down so that there is no gap between the web and the platen. This feature is conducive to quality printing because the print need not move the label and ~he web toward the platen and because if it can be assured that the web lies against the platen, then the distance ~etween the print head in the home or rest position and the platen can be kept to a minimum. It is pr~f~rred that a die roll be used to urge the supporting material web against the toothed feed wheel . In addition, the die roll is spring-urged against the web to accommodate for manufacturing variations in the labeler. The die roll is carried by a holder which is nested i~ the subframe and which includes a pair of leaf springs. Thus, adequate mating cooperation between the die and feed wheels is assured. A leaf spring is disposed in cooperation with the web where it is fir~t paid out a~ the label rollO The leaf spring has a mou~ting portion keyed to the subframe.
Th~ leaf spring is conducive to the gradual paying out of the web from the labeL roll. The leaf spxi~g and its mounting portion are comprised of one-piece molded plastics material.
There is a brak~ which acts on the composite la~el web between the place where the compo~ite web is paid out of the label roll and the plat~n. The brake includes a roll which is Docket M-340 loosely mounted in the subframe and the print haad carrier leaf springs which contact a brake roll at spaced-apart locations. The use of such separate leaf springs is con-ducive to effective braking action against the composite web in spite of manufacturing variatio~s.

The frame sections 32 and 33 are mates to each other and are substantially mirror-images o each other.
A sub~rame generally indicated at 40 is shown to include subframe sections 41 and 42. The subframe section 41 is shown to have male projections 43 received in and held in a snap-fit manner in apertures 44. With reference also to FIGURES 4 and 5, the subframe section~ 41 and 42 have res pective ball tracks 45 and 46 for receiving respec~ive xolling-co~tact bearing members specifically ball-bearing strips 47 and 48. The subfxam~ sections 41 and 42 have respective guideways 49 and S0 and 49i and 50 ' . The subframe sections 41 and 42 have respective posts 51 and 52 and 51' and 52 ' for receiving respective ~ubular rollers 53 and 54. The posts 51 and 51' rotatably mount the tubular roller 53 and ~h~ posts 52 and 52' ro~ata}:)ly mourl~ the tubular roller 54.
The subframe sections 41 and 42 have respective round holes 55 and 56 for rotatably mounting a feed wheel assem~ly generally indicated at 570 The subframe sections 41 and 42 have res-pective non-circular, specifically dove-tail, recesses 58 and 58' for receiving a holder 59. The holder 59 is of one-piece molded plastics construction and includes a pair of lea springs or spring fin~ers 60 and 61 having a pair of res-pective sockets 62 a~d 63. The sockets are prefarably open-sided and preferably extend for more than 180 but substantially Docket ~340 ~ ~ ~ 5~
less than 350 so as to receive respective stub ends 64 and 65 of a die roller 66. The die roller 66 has a pair of grooves 67 that correspond in contour and alignment to teeth 68 of toothed feed wheel 69 of the assembly 57. The teeth 68 are staggered and axe disposed in two annular rows. A guide plate 70 which is disposed between the rows of teeth 68 has oppositely extending posts 71. The posts are received in h~les 72 and 73 of the respective subframe sections 41 and 42 to confine the supparting material we~ S of the composite web C in proxLmity to the surface of the feed wheel 69~ The subframe sections 41 and 42 ha~e respective non-circular recesses 74 and 74' for keying end portions of a non-circular post 75 of a latch 76. A bar 76" is connected to the post 75 by a leaf spxing 77. The bar 76" has a pair of manually engageable projections 78 and 79 which extend through res-pective openings ao and 80' in sub~rame sections 40 and 41and through respective openings 81 and 81' in the frame se~tions 32 and 33. Shields 82 and 83 are disposed inbound of the projections 78 and 79. The shield 82 is disposed between the ~rame section 32 and the subrame section 41 and the shield B3 is disposed between the frame section 33 and the subframe section 42. ~he shields 82 and 83 serve to keep dust out of the inside of the labeler 30. The subframe sec io~s 41 and 42 have elongated recesses 84 and 84'.
Marginal side portions of a platen 85 are received in the r~spective recesses 84 and 84' and marginal ends oE a de-laminator, specifically a peel roller 86, are received in the same elongated recesses 84 and 84'~ The peel roller 86 is in direct contact with shoulders S7 at the ends of the marginal Docket M-340 ~ ~ 2 5`~ ~
sides of the platen 85. The shoulders B7 define an end edge of the platen 85. There is a minimum of friction between the shoulders 87 and the peel roller 86 because o~ minimal contact.
In addition, any non linearity of the peel roller 86 will have Little or no effect because only the end portions of the peel roller 86 are contacted by the shoulders 870 It is apparent that both the platen 85 and the peel roller 86 are captive in the same respecti~e recesses 84 and 84'. The guideways 49 and 49' are fo~med in part by guides 8B and 8~.
Spaced from the respective guides 88 and 89 are projections 90 and 91. A hsld down and guide member generally indicated at 92 i5 shown to have a hold-down or guide member 93 which is disposed in overlying relationship with respect to the platen 85 and a direction-changing gui.de member 94. A mounting m~mber 91' is interlocked between guide 88 and projection 90 and between the guide 89 and the projection 91 as shown in FIGURES 1 and 20. In addition, the subframe sections 41 and 42 have posts 95 and 95' received in a hole 96 in the member 94.

The resilient device 105 is shown to be disposed in ov~rlying relationship with respect to label roll R adjacent the place where the composite we~ C is paid out. The composite web C passes over the resilient device 105 and from there between the roller 102 and brake surfaces 109 and 109'. The brake 103 also includes a plurality of separate spaced-apart leaf springs 103', ~pecifically ~wo, which ar~ in contact wi~h the O-rings lQ4' of the rollex 102 at spaced apart locations. The use of at least two such springs 103' facilitates reliabLe braking in spite of manufacturing variation~.
The frame 31 has a handle generally indicated at 110 : and includes handle portions 111 and 112. The posts 37 and 37' are disposed at the outer end portion of the handle 110.
A manually operable ac~uator generally indicated at 113 is sh~wn to include a lever 114 having a hole 115. The posts 37 and 37' are received in opposite ends of the hole 115 to pivotally mount the actuator 113. The actuator 113 is shown to includa a pair of spaced-apart gear sections or segmental gears 116 and 1170 The gear sections 116 and 117 mesh with respective gears 118 and 11~ rotatably mounted on an axis A'.
A print head generally indicated at 120 includes a pair of racks or gear sections 121 and 122 which mesh with respecti~e gears ~5 118 and 119. A resilient device generally indicated at 123 bears against ~he handle 110 and 110' and against the inside of the actuator 113 to urge the a~tuator 113', the feed assembly 57 and the print head 120 to their initial or rest positions as shown in FIG~RE 3. The resilient device 123 is shown to include a compression spri~g 124 which urges sections 125 and 126 to extended positions with respect to each other.
Docket M-340 The print head 120 is shown to have two sets of ~ pri.nting members 127 and 128 (FIGURES 1, 3 and 6) for printing ; two lines of data on a label L. The lin s are printed in fields F and F' disposed on opposite sides of the hcld~down member 93. Each line of printing members 127 and 128 has selectively manually settable selectors 129 and 130 so that each line can print the selected data on the label h. The print head 120 also has a pair of tracks 131 and 132 co-operable with respective tracks 45 and 46 of respec~ive subframe sections 41 and 42. The ball hearing strip 47 is in rolling contact with and between the tracks 131 and 45 and the ball bearing strip 48 is in rolling contact with and between the tracks 46 and 132. Accordingly, the print head 120 is mounted for movement into and out of cooperation with the platen 85. The racks or gear sections 121 and 122 are shown to be straight as are the tracks 45, 46, 131 and 132 so that the print head 120 moves in a straight line as is pxeferred.
With re~erence to FIGURES 14 and 15, the eed assem~ly 57 is shown to include the feed wheel 69 and a drive wheel, specifically ratchet wheel 133 having teeth 133' dîsposed in an annular arrangement. The feed wheel 69 and the ratchet wheel 133 are shown to be selectively movable with resp~ct ~o each other. The feed wheel 69 is shown to have an annular rim 134 which is connected to a tubular hub portion or pr~iection 135 by a web 136. The tubular portion 135 has an open end 137 and a closed end portion 138. The tubular portion 135 is shown to be rotatably mounted in an annular hole 139 in tha subframe section 41. A projection or retainex 140 joined to the end portlon 138 extends in the axial direction. The ratchet wheel 133 includes a plurality, specifically three, spring fingers 142 having respective . ~
f~5~ ~
Docket M~340 projections or teeth 143. The spring fingers 142 extend through elongated slots or holes 144 in the web 136. When the ratchet wheel 133 is assembled onto the fe~d wheel 69, the projections Lnitially cam the spring fingers 14~ inwardly and as the projections 143 pass through the holes 144, they snap radially outwardly so that the ratchet wheel 133 is coupled in a~sembled relationship to the feed wheel 69 for limited rotational movement. The ratchet wheel 133 is therefore adjustable to a limited extent as limited by the leng~h of the holes 144. The ratchet wheel 133 has a clutch member 145 with an inner surface beveled with respect to axis A' which is provided with a plurality of small closely spaced teeth 146~ A clutch member generally indicated at 147 is shown to have a plurality of mating l:eeth 148 disposed on a bevel for cooperation with the teeth 146 of the clutch member 145. The clutch member 147 has tubu:Lar portions 149 and 150 which extend in opposi~e dir~ctions. The tu~ular portion 149 has a closed end portion 150' with a coi~ slot 151. A
three-lohed ~eat 152 is joined to the end portion 150'. The outer surface of the tubular portion 150 is splined, having what is illustrated as being three splines 153 which are received in a splined hole 154 in the tubular portion 135.
The splined hole has spline grooves 1S5. Accordingly, the clutch member 147 is keyed against rotation with respect to the feed wheel 69 but is slidable axially with respect $o the feed wheel 69. The connection between the clutch member 147 and the feed wheel 69 is considered to be a splined connection.
A compression spring 156, received within the tubular portions 135, 149 and 150, bears at its opposite ends against the end por$ion 138 and the seat 152. The projec~ion 140 ser~es to locate and retain the spring 156 approximately axially disposed within the feed wheel 69. The position of the clutch members 145 and 147 relative to each other can be varied by the user //
Do~ket M-340 ~ ~ ~ 5 ~ ~
by simply inserting a coin into the slot 151 and exerting an inward force to compress the spring 156, and as goon as the teeth 146 and 148 of the respecti~e clutch me~bers 145 and 147 are ou~ of clutching engagement, the user can rotate S the tubular portion 149 and hence the clutch member 147 and move it to a different selected position with respect to the clutch member 145r Rotation of the clutch member 147 causes simultaneous rotation of the feed wheel 69 because of the splined connection. As soon as the user releases ~he force on the end portion 150', the spring 156 returns the clutch member 147 into clutching e~gagement with ~he clutch member 145.
The ~ear 118 is shown to be rotatably mounted on the projection 135 between the frame section 32 and the subframe section 41. The frame section 32 has an annular boss 157 which is shown to be out of contact wi~h the tubular portion 135 bu~ in contact with the gear 118. Accordingly, the gear 118 is captive between the subframe section 41 and the bos~ 157. Th~ gear 119 includes an annular rim 158 with teeth 159 at its peripheryO A web 160 is joined to one side of ~he rim 158 and to a tubular hub portion 161. The hub portion 161 is rotatably mounted o~ the tubular portion 149.
The weh 160 abuts the texminal end 162 o~ the ratche~ wheel 133 and the tubular portion 161 abuts the end o a~ a~nular flange 163 of the frame section 33. Neither the frame section 33 nor its flange 163 contacts the tubular portion 149. Accordingly, the gear 119 is held captive between the ratchet wheel 133 and the flange 163~ It is apparent that the eed assembly 57 is mounted to the subframe 40 which in turn is mounted by th~
frame 31. The adjustment is made from only one side of the Coc~et M~3~0 frame 31 without tne need to shift the f~ed or drive wheels relative to each other. The gear 119 carries a pawl unit generally indicated at 164. The web 160 has a hole or aperture 165. Th~ pawl unit 164 has an integrally formed snap pro~
jection generally indicated at 166 which includes a split pivot or post 167 and projections 168 with beveled cam faces 169. In the position shown in FIGURE 17, the pivot 167 rotatably mounts the pawl unit 164 to the gear 119 and the projections 168 prPvent the pawl unit from being separated rom the gear 119. The cam faces 169 facilitate connecting the pawl unit 164 to the gear 119. In assemblins the pawl unit 164 onto the gear 119, the cam faces 169 are inserted into the hole 165, and by pushing the pawl 164 further into the space within the rim 158, the pawl 164 is coupled for pivotal movement as shown in FIG~RE 17. The pawl unit 164 includes a pawl 16~' having an integral projection or post 170 which can move to a limited extent in a slot 171. The projection 170 can cooperate with a stop face 172 to limit the travel of the pawl 164'. Without a means to limit the pivotal movement of ~he pawl 164' it would be more difficult to assemhle th~ pawl unit 164 with the ratchet wheel 133 because the pawl unit 164 could assume any of a wide variet~ of positions. Once th~ pawl unit 164 is assembled into coopera-tive re~ationship with respect to ~he ratchet wheel 133, the ratchet wheel 133 holds the pawl unit 164 in a position in which the projection 170 is out of contact with the stop face - 172. However, i the gear is disassembled so that the pawl 164 is moved out of contact with the ratchet wheel 133, the stop face 172 again cooperates witn the post 170. Formed integrally with the pawl 164' is a leaf spring or spring finger 173~ The leaf spring 173 is connected to the pawl 164' adjacent the pawl tooth 174 and the other end portion ~ ~ ~ 5~3 Docket M~340 of the leaf spring 173 contacts the underside of the rim 158.
The spring 173 urges the pawl tooth 174 into the path of the teeth 133'~ It is seen that the pawl unit 164 is disposed almost entir21y within the space defined by the rim 158.
When the user actuates the actuator 113, the gear segments 116 and 117 rotate gears 118 and 119 which move the print head 120 into printing cooperation with the plat~n 85, and the pawl tooth 174 moves into position to cooperate with the next tooth 133' on the ratchet wheel 133~ When the user releases the actuator 113 the resilient device 123 urges the actuator clockwise as viewed in FIGURE 3 to return the print head 120 to its initial position shown in FIGURE 3 and to dri~e the pawl 164' to advance the ratchet wheel 113 and hence the feed wheel 69.
~ith re~erence ~specially to FIGURES 1, 22 and 23, the label roll R is shown to be mounted for rotation on hub members 17S and ~76. The hub members 175 and 176 are mounted on leaf springs 41' and 42' formed integrally with subframe sections 41 and 42. The hub members 175 and 176 are identical.
Hence, only the hub member 175 will be discussed in detail.
Th~ hub member 175 is generally disc-shaped and has an annular hole 177. The leaf springs 41' has an annular flange 178 received in the hole 177 for rotatably mounting the hub member 175. The hub mem~er 175 is retained on the flange 178 ; 25 by a retainer generally indicated at 179. The retainer includes an annular disc-shaped portion 180 and a split shaft or post 181 ha~ing a pair of projections 182. The shaft 181 can be inserted through a hole 183 to ~he position shown in FIGURE 22 and the projections 182 hold the retainer 179 in the assembled position. A pair of identical discs or side plates 184 and 185 ar~ used to support the sides of the roll 5.`~
Docket M-340 R ~o that the roll R does not telescope. The discs 184 and 185 can be assembled onto the appaxatus even after the retainers 179 are in place. The disc 185, for example, has a pair of holes 186 and 187 which communicate with each other at a gap 188~ The gap 18a is defined by projections 189. The hole 186 extends through more than 180 but substantially less than 360. The hole 187 is at least slightly larger in diameter than the outsida diameter of the hub member 175.
The hub member 175 can be inserted through the hole 187 and ~hereupon the disc 184 can be shif~ed until a boss 190 on the hub member 175 deflects the projection 189 and is received in the hole 1860 The disc 184 is composed of a resilient material, preferably a thin sheet of transparent plastics material. The disc 184 can be assembled onto ~he apparatus after the hub member 185 and the retainer 179 are in their assembled position, even though the outer periphery of the disc 134 is continuous.
With reference to FIGURES 1, 3, and 6 through 9, ther~ is shown a movable bod~ section or cover generally îndicatçd at 191 for mounting an inking mechanism generally indicated at 192. The cover 191 is pi~rotally mounted on the posts or shafts 34 and 34'. The post 34 together with the post 34' can be considered to be a post or shaft. The cover 191 is a pair of spaced side walls 193 and 194 joined by a panel 195. The section 191 has a pair o spaced apart arms 196 and 197 which are bifurcated and which have snap soc~ets 198 and 199. The snap sockets 198 and 199 have aligned sockets 200 which are annular in configuration and which extend through more than 180 but substantially less than 360 as shown. The sockets 200 are axially aligned and can receive the respec~ive posts 34 and 34'~ It Docket ~-3~0 ~ ~ 5 '~
is apparent that the cover 191 can move between a normally closed position shown in FIGURE 3 and an open position shown in FIGURE 6. The saction 191 can be easily assembled onto the posts 34 and 34' and the user can remove the entire cover 191 and replace the entire inking mecha~ism, if desired. The panel 195 has a pair of slots or cutouts 201 and 202 to enablP the knobs 129 and 130, which are part of the print head 120, to move as the print head 120 moves between the initial or rest position shown in FIGURE 3 and the printing position in which the print head 120 cooperates with the platen 85. The cover 191 can be readily latched in the closed po~ition by latch assembly 76. The assembly 76 is formed in part by projections 204 on ~he cover 191 which have respective cam fac s 205 which terminate at shoulders 206.
The assembly 76 is also formed in part by the latch 76'.
When the cover 191 is moved to the closed position, the cam fàces 205 contact cam face 207 on the bar 76" thereby causing the leaf spring 77 to bend as the bar 76 n mDves generally to the right as shown in FIGURE 3. When the shoulders 206 have cleared the cam face 207 they move into underlying relation-ship with respect to the bar 76" and the leaf spring 77 returns the bar 76" to the position shown in FIGURE 3. The cover 191 is now latched in the closed position. To unlatch ~he latch assembly 76, the user manually engage~ the projections 78 and 79 and moves them rearwardly away from the front o~
the apparatus 30. When the shoulders 206 are clear of the bar 76" the cover 191 can be pi~oted to the open position.
The cover 191 has a pair of dove-tail slots 208 and 209. The slots 208 and 209 can slidably receive mating dove-tail bearing blocks 210 and 211. The bearing bloc~s have respective aligned holes 212 and 2130 When the blocks 210 and 211 are slid into their respective slots 208 and 209 shallow projections 214 and 21S respectively project slightly 1~ .
Docket i~ 3 4 0 into the respective holes 212 and 213. There is enough resiliency in the materials of which the cover 191 and the bearing bloclcs 210 and 211 are composed o let the bearing blocks 210 and 211 slide into place to a position in which the projections 214 and 215 extend into respective holes 212 and 213. .~ inker body or carrier genexally indicated at 216 and shown in considerable detail in FIGURES 10 and 11 has a pair of side members 217 and 218 and a pair of transve~se members 219 and 220~ Arms 221 and 222 are connected to the respective side members 217 and 218. The arms 221 and 222 have respective aligned holes 223 and 224 for receiving respecti~e stub ends 225 and 226 of ink roller 227. The side members are roughened as indicated at 228 and 229. When it is desired to remove the ink roller 227 the side members 217 and 218 are grasped by and between the thumb and index fingers at the roughening 228 and 229 and squee~ed so that the arms 221 and 222 spread apart. The stub en.ds 225 and 226 will ac~ordingly fall out of the respective holes 223 and 224 and a new ink roller 227 can be mounted to the arms 221 and 222 ~y simply squeezing the side members 217 and 218 to spread the arms 221 and 222 to receive the stu~ ends 225 and 226.
The side members 217 and 218 diverge outwardly and have outwardly extending aligned mounting portions 230 and 231, on arms 230' and 231', received in the holes 212 and 2130 The mounting portions 230 and 231 are received in the res-pective holes 212 and 213 of bearing blocks 210 and 211 while the bearing blocks 210 and 211 are slid into slots 208 and 209. Thereafter the carrier 216 is swung into the position shown in FIGURE 3. In this position the arm 230' is disposed for movement between the surface 208' and interference member 201' on the panel 195 and the arm Z31~ is disposed for movement between the surface 209' and interference member 20Z' on the ~ocket M-340 ~25 `~
panel 195 so that the carrier 216 cannot be disconnected from the cover section, as when the labeler 30 is dropped~ With reference to FIGURES 1 and 3 r a spring member generally indicated at 232 includes a leaf spring or spring finger 233, S a transverse connector or m~mber 234 disposed at one end portion of the leaf spring 233, a mounting portion 235 disposed at the other end portion o the leaf spring 233, and another mounting portion 236. The mounting portion 236 is bifurcated and receives an end por~ion of the panel 195. The mounting portion 235 has an elongated slot 237 which receives the post 34 ~o provide a pin-and-slot connection. The mounting portion 235 is disposed between rolls 238 and 239 of an applicator roll 240. As best shown in FIGURE 12, the rolls 238 and 239 straddle the mounting portion 235 and the arms 196 and 197 straddle the roLls 238 and 239 and the mounting portion 235.
The transverse member 234 is received in aligned elongated holes 241 and 242 of a pin-and-slot connection. The transverse member 234 has opp~si~ely extending tran~verse por~ions 243 and 244~ The transverse portion 243 extends into the hale 241 and the ~ransverse portion 244 extends into the hole 242.
~he transverse portion 243, for example, can be inser~ed into the hole 241 while the transverse member 234 is canted with resp~ct to the axis of the holes 241 and 242 and moved into posi ion and thereafter the other transverse portion 234 is moved into alignment with the hole 242~ When the transverse portion~ 243 and 244 are received in respective holes 241 and 242, the spriny 232 can be brought to its normal position in which the sides o the spring 232 are disposed between opposed shoulders 245 and 246 which limit the lateral movement o the transverse member 234. The transverse portions 243 and 244 Docket M-340 are long enough to prevent them from coming out of the respective holes 241 and 242 when the shoulders 245 and 246 cooperate with the sides of the spring 232.
In the initial or rest position of the print head 12U, the spring member 232 urges the carrier 216 to the solid line position shown in FIGURE 3. The carrier 216 has a pair o spaced-apart snap sockets 247 and 248 (FIGURES 10 and 11) having aligned openings 249 and 250~ Stub ends 251 and 252 ~FIGURE 1) of a roller 253 are received in respective openings 249 and 250. The openings 249 and 250 extend through moxe than 180 but substantially less than 360 so that the stub ends 251 and 252 can be snapped into them. The print head 120 carries a c~m ganerally indicated at 254 with a dwell portion 255, a relatively steep ramp 256, and another dwell portion 257. The ink roller 227 is shown to be spaced from ~he print head 120 in FIGURE 3, when the roller 253 bears against the dwell portion 255. When the print head 120 moves toward the inX roller 227, the endmost printing me~bers 127 and 128 con~act the ink roller 227. About that time, with continued movement of the print head 120, the roller 253 rolls in contact with the ramp 256 to pivot the carrier 216 clockwise as viewed in FIGURE 3. r.~hen the prin~ head 120 is in printing cooperation with the label L on the platen 85, the carrier 216 and the ink roller 227 which it carries are in the position indicated by phantom lines PL'. When the print head 120 is in printing cooperation with the label L, the roller 253 is in cvntact with the dwell portion 257. As the print head 120 is returned to its rest or initial position~
the roller 253 moves out of contact with the dwell portion 257, thereafter the roller 253 rolls along the ramp 256, and thereafter the roller 253 rolls onto the dwell portion 255 ~oGket M-340 until the caxrier 216 and its roller 227 are returned to ~he initial position. Because the carrier 216 moves on fixed pivots, a lost-motion connection is provided by the elongated holes 241 and 242 and a lost-motion connection is also provided by enlarged hole 237 in the mounting portion 235.
In operation, a label roll R is loaded onto the hub members 175 and 176 between the discs 184 and 185. The roll R consists of the composite web C composed o a web of supporting material S to which the labels L are releasa~ly . adhered by pressure sensitive adhesive A. The leading marginal end of the composite web C is passed over the resilient device 105, and between the brake roller 102 and the surfaces 109 and 109'. It is preferred to squeeæe the actuator 113 slightly while the leading marginal end is being threaded through the labeler so that the print head 120 is moved away from the initial position to release the brake 102 and so that the brake roller 102 doe~; not exert a braking force on the composite web C. The leadi~g end portion of the composite web C is passed alons the guideway provided by ~;
~ guides 49 and 49'. The composite web C then passes out o~
the front of the apparatus adjacent the roller 54 and thereupon the u~er inserts the composite web C between the platen 85 and the hold-down member 93. The guide por~ion 94 guides the composite web out of the apparatus to a position where it ca~
be grasped by the user who will pull on the composite web C
to draw several additional inches off the roll R. The com-posite web C is thereupon passed around the roller 53, and with the actuator 113 preferably in the fully squeezed or fully op~rated position, the leading end of the composite web C
Docket M- 340 is ~nserted between the die roller 67 and the feed wheel 69.
T~hen the actautor 113 is released, the teeth b8 break through a f rangible portion FS on the supporting material web S
and the rPlated frangible portion FL of the label material L.
Repeated actuation of the actuator 113 will cause any slack to be taken out of the web S and thereupon labels h will be dispe~sed int~ label applying relationship with the applicator 240 as shown ~n FI~URE 3. In this position the trailing ; marginal end of the leading label L is still adhered to the web S. When the user appli~s the label L~ the label L being applied is pulled from the web S. The brake 103 is effective to prevent the composite web C from being paid out of the roll R during application o a label L and an anti-backup pawl 258 ~FIG~RE 1) which cooperates with the ratchet wheel 113 obviates loss of tension in the wab S.
When it is desired to replac~ an ink roller 227, the user pulls on the knobs 78 and 79 to move the bar 76"
away from the shoulders 206 on the cover section 191. The user can thereupon pivot the cover section 191 to ~he ope~
position shown in FIG~RE 6. By squeezing the side mem~ers 228 and 229, the spe~t ink roller falls out of the holes 223 and 224, A new i~k roller can be inserted by squeezing ~he side members 228 and 229 so that the holes 223 and 224 can r~ceive the stub ends 225 and 226 of a fresh ink rollex. Thereupon the user xeturns the cover section 191 to the position shown in FIGU~E 13. The cams or cam faces 205 on the cover cooperate ~;
with the cam face 207 of the bar 76", thereby de1ecting the leaf spring 227 until the cover section 191 is latched in the position shown in FIGURE 3.
