CAIN-LABELING MACHINE.

Application filed May 5, 1926. Serial No. 106,885.

The invention relates to machines for labeling cans or cylindrical packages of the type in which the cans are passed through the machine by rolling along a runway or ways. The labels are placed beneath the runway in a pack from which they are re moved successively by the cans as they pass, the label which is on top in each instance being picked up, i. e., caused to adhere to the can as it rolls over it, by means of the paste or cement which holds the label, or more correctly the near or forward end of the label in its final position on the can, the far end or lap end of the label being secured by adhesive applied by separate means from a separate source. The termsnear and far and upward and rear have reference to the position of the labels in the machine,-the front of the machine being the point at which the cans are fed into it. a

The present invention relates primarily to a machine in which the adhesive which secures the forward end of the label to the can is applied directly to the label. The can as .it passes rolls over the labeland the paste coated forward end'of the label, sticks to the can winding or rolling the label about the can as the latter advances, Adhesive for the lap end is, separately applied as already outlined, I

The object of the invention is to provide improved means for applying the adhesive and. controlling the same by the passing cans, so that the adhesiveis affixed to the labels at the instant they are placed on the cans preventing premature drying of the adhesive and making regular feeding nonessential. As each label is picked up and the next label beneath is exposed the pasting mechanism is made ready for application of adhesive to the newly exposed label so that there i no opportunity for the paste to dry on the label and the can which is next to pass operates the mechanism for applying'adhesivc to the label so that each label when picked up by the can is freshly coated with adhesive.

In previous machines of this type difa veconomizes the productlon of an unsightly package on ency of the adhesive to dry on the labels so they do not stick to the can. Also the paste accumulates on the belts, rollers and labels, by and to which it is applied, giving the label an irregular, bumpy, smeared and uns1ghtly appearance. This difiiculty is en- 5 account of the use of an excessive amount of paste or cement, but has the further-ad '70 vantage that the paste or cement applying mechanism being in operation for a small fraction of the total period of operation of the machine, a considerable amount of power is saved. I The new machine hasthe further advan tage that it may be used with but slight ad justment in applying both full length labels which extend entirely around the can, and

panel labels which extend about a part only of the circumference of the can.

In this connection it is noted that in applying paste to the labels before they are picked'up by the cans the paste must be rubbed over the surface of the label and 35 there is a considerable tendency in this operation to displace theltop labels from the pack on account of their tendency to adhere to the cement or paste applying device. This tendency has been overcome in the present instance by the provision of a presser foot which engages one end of the label, the applying means being drawn over the label toward the other end.

This presser foot, however, might have a tendency to either tear the labels when they are picked up by the cans or cause them to slip relatively to the surface of the can by pulling them over the surface of the can displacing them from the position which they have taken in picking up, as described, and causing them to fail to stick or to be inaccurately located on the can.

To overcome this difficulty the machine of the present invention is provided with means for raising the presser foot to release each label in turn simultaneously with the picking up operation. In the accompanying drawings I have illustrated a machine embodying the improvements of my inventionin the preferred form.

Referring to the. drawings by numerals,

. each of which is used to indicate the same or similar parts in the different figures, the machine as shown comprises supports or legs 1 on which are mounted longitudinal side bars or

frames

2, 3. -The machine also in cludes pulley drive 4. and idler pulley 5 at the opposite ends on which runs the can belt 6 contacting the cans fromabove and by means of which the cans are passed through the machine rolling on the waysi. The belt is driven from any suitable source, as an electric motor, not shown, which in the pre ent form of the machine is mounted on the supporting frame near'the floor. This motor drives the diagonal shaft 8 in F igure 6 which operates the belt driving pulley 4 byway of suitable gearing contained in the gear case 9.

As already outlined the invention relates particularly to the paste applying mechanism and the manner of actuating the same intermittently to correspond to the presentation of the cans.

In Figures 4, 10 and 11 I have illustrated the primary intermittent drive for the paste applying means, the same consists of a shaft 11 mounted in suitable bearin s 12 in the frame and extending across'ilie machine. This shaft carries loosely mounted thereon a sprocket-15 driven by a chain 16 from a sprocket 17 secured to the belt pulley 5. The sprocket 15 is providcdwith a projecting clutch member 18 on the right in Fig ure 1], the same having clutch teeth 19 which cooperate -with clutch teeth 20 on a sliding clutch member 21, which is keyed to the shaft 11 by means of a key 22. A coil spring 24 encircling shaft 11 at the right of the sliding clutch member imparts to it frame, as shown in Figure 4. .The arm 27.

a tendency to move to the left into engage ment withthe clutchmember 19 on the sprocket The clutch member 21. is controlled by a sliding bolt operatedby an arm 27 secured to a shaft 28 having. a bearing in the is provided with a horizontal foot. 29 through which the bolt is passed, the bolt having secured thereto a collar 30 which [rests on the arm, the bolt 25 being also 1, 4 and 'Z, which extends across the path.

- of the cans, the arm 34 as it swings about the shaft 28 has a vertical motion, being in its upper position in the path of the cans as aforesaid. This refers particularly to a cross bar 36.,

As each can passes along the Ways, the cans being fed from the right to the left, Figures 1, 2, 3, 4, 5 and 6, it engages and depresses the arm 3-4, which is held in its upper position by the spring 33, thereby rocking the shaft 28, as seen in Figure 4, in ii ght handed rotation, raising the arm 27 with the foot 29 and the bolt 25.

The bolt 25 in its advanced or depressed position engages a cam path or shoulder 37 on the sliding clutch member 21, which cam path as shown particularly in Figure 11 is inclined to the axis of the clutch member. In the position shown in Figure ll the bolt 25 being advanced, engages the high point 40 of the cam surface 37 holding the sliding clutch member 21 out of engagement with the clutch member 19 cru'rie-d by the continuously rotating sprocket 15. When, however, the tripping lever 34 is depressed by the passage of a can along the ways, the arm 27 being swung upwardly in right handed to tation withdraws. i. or, raises the bolt 25 and permits the clutch member 21 to move to the left into engagement with the clutch member 19. Under these circumstances, the

clutch members being in engagement, the

shaft 11 is rotated, the bolt 25 is, however, immediately released by the passage of the can over the arm' 34, which arm is imme diately raised, the bolt being simultaneously advanced or depressed by the action of the spring 33. As soon as the. can has passed the arm 34 the latteris released and tends to rise impelled by the tendency to left handed rotation about the shaft 28 imparted to the arm 29 by thespring 32. The bolt however, encounters the peripheral surface 38 of the cam from which it is dropped in due course by rotation of the cam bringing the low point thereot, 39, opposite the bolt whenthe latter is engaged by the cam from the right hand side in Figure 11 after the manner, of a follower, and cont'ainued rotation of the shaft 11 brings the high point 40 of the cam again in contact with the bolt causing the clutch-to be released. In this way a single rotation is imparted to the the functioning of the intermittent gearing and the corresponding operation. of both pastingmechanisms, the term pasting being used for convenience, in connection withthe application of glue, cement or paste.

, The cansas they enter the machine are spaced or timed by means of a can gate 43,

which, in the form of the invention shown, is placed at the forward end or the ways 7, see-Figure 4, also Figures 7 and 8, and at. the delivery end of the feed chute. 44.

the passage of nd from this This gate 4:3 in the form of the invention shown is integral with a pivoted or trigger section 45 of the ways 7, consisting of two tracks 45 connected by cross braces 45",

which is pivotally mounted on a transverse shaft 46 beneath the ways to operate the gate. The gate 43 is shown as in the form oftwo uprights, one. at the end of each track 45 of said way section 45. This can gate 43 operates in a transverse slot 47, onlone side of which slot is therear end 49 of the chute 44 and on the other the forwardend of an inclined runway 48, .down which the cans roll on to the ways 7. The forward portion of the trigger section 45iis depressed at 50 beneath the mummy-48. The trigger section 45 of the ways, as shown, is also notched at 51 to provide for the operation of the arm 34 without interferen e of said of the said operation.

J The rearward end 52 of the trigger section 45 of the ways 7 is sutliciently spaced of sufiicient length to so time or space the cans as to permit the pasting mechanism to operate intermittently as already suggested without interference of one can with another and it prevents the presentation of a arm with the operation ofthe trigger, the

two being differently timed for certain parts from the gate43, i. e., the trigger section is can to the label pack after the passage of" the previous can before the mechanism is ready to receive it. The gate is held normally depressed by helical tension springs 53. There are two springs as shown in Figure 8, said springs being connected at them upper ends to the gate at 54, Figure 8, and at their lower ends to depending brackets secured toa stationary portion of the frame, the connections being indicated by referents character 56, the normal position ofdthe gate being as shown in Figures 4 an 7.

As each can is admitted to the machine from the chute 44, it passes over the gate 43 which is normally in depressed position and down the incline 48, see Figure 7, coming immediately in contact with the pivoted section 45 of the ways 7, which, when the gate is depressed, is inclined upwardly'to the rear as shown in Figure 7. Simultaneously the can is engaged from above by the can belt 6 and moved forward independently of the momentum acquired by the inclines which it has just passed, and the swinging section 45 is by weight otthe can thus rotated downward into horizontal position as shown in dotted lines in Figure 7. This raises the gate into the path of the next can, The swinging or rearward end 52 of the trigger then rests on the frame, particularly the cross bar 57, which is stationary and as shown extends from the side bar 2 to'the side bar 3 on the other side, resting on both members. The cans accumulate on the chute and as each can is released by the gate it moves quickly down the incline and contacting the member 45 closes the gate in time to stop the next can before it acquires headway.

.To overcome the tendency of the cans on account of their momentum and other agencies, to hop over the gate when the latter is partly or fully raised, means has been provided in the nature of a can check 59 placed over or substantially over the gate and spaced above the floor of thechute 44 by slightly more than the diameter of a can.

' This prevents the passage of the cans over the gate unless the latter is as low as or be-- low the chute floor, i. e., in open or lowered position. This can check consists. of'a strap or bar which may be described as U shaped in cross section, the same having legs 60 secured by bolts 61 to the uprights 62 which carry the belt pulley 5. The can check moves up and down with the adjustment of the pulleys and the uprights 62, as will be easily understood, the upright being vertically slidable through bearing 63 and held by cap screw 64. Section 45 of the ways 7 is held in depressed or horizontal-position by the can until the latter has passed the rearward end 52 of the swinging section and in this position the check or gate 43 is in a position in which it obstructs the passage of the cans, see the dotted line position of the same in Figure 7. As each can passes the trigger 45, releasing the same by moving ofi of the end 52 of the swinging section of the ways, the latter swings upwardly to the normal position in which it is illustrated in Figures 4 and 7. In this position of the swinglng section the gate belng lowered to the full line position, Figures 4 and 7, the next can is admitted to the machine moving forward immediately on the lowering of the gate from the path of the cans. By this operatron, i. e., the release of one can permitting it topass the gate when and not unless the next preceding canhas passed from the end of section 45,- the cans are timed and spaced by a distance exactly equal to the length of the member 45 from and including the rearward or swinging end 52 to the gate 44.

The pack of labels 58 is supported on any suitable type of label table 65, see Figure 9, and the cementor pick-up adhesive is applied to the forward end of'each label as it comes to the top of the pack in turn by means of a pick-up paste roller 66. This roller is fed or supplied with paste by means of a paste pot roller 67 which rotates in the pick-up paste pot or cement pct 68, see Figures 12. 13 and 14. The pick-up paste roller 66 is applied to the paste pot roller 67 and to the top ,label of the pack 58 alternately by the following mechanism.

The machine is provided with a depending bracket 69 in the lower end of which is seated a stud 71 on which an arm 7 O is pivotally mounted to swing in a fore and aft vertical plane; The arm 70 extends upward from the stud 71 to the level of the side bars 2, 3 and carries pivotally connected to the upper end of the arm at 72 a connecting rod 7 3 which is offset at 74 upwardly to the plane of the ways, from which point it extends rearwardly to the roller 66. Figure 9, where it is offset downwardly at 75. being provided at its rearmost lower end with a bearing for the roller shaft 76. The arms 70 and connecting rod 73 are duplicated on the opposite sides of the machine forming actuating means and a support for both ends of the roller. The upright arm 70, in the machine shown the one of said arms on the far side of the machine, see. Figure 4, is actuated by means of a connecting rod 78 pivotally connected at one end to a central point on the upright arm 70 at 79 and at the other end by means of a crank pin 80 to the swinging end of an arm 81 on the shaft 11, already described as carrying the clutch 18 and intermittently opermeans of a cam path and switch,'Figure 9, engaging the shaft 76. The cam consists of a plate 83 secured to each side frame memher and having a cam path opening 84, the outline of which conforms roughly on the upper side to the path of the upper side of the shaft on the rearward motion of the roller and as to'the lower side to the path of the bottom of the shaft on the forward stroke ofthe roller. The roller shaft "('6 is guidedinto thenpper or forward path by means of an automatic switch 85 which is rearward path of the roller shaft. The

lower forward-end of the switch is preferably pointed at 88 and the cain opening 84 is provided with a pocket 89 on the lower rearward. side of theopening into which the point of the switch drops by gravity when the roller shaft is in the forward lower extremity of the cam opening which occurs when the pasting roller 66 is in contact with the paste pot roiler 6?. A spring 86 may assist in throwing the switch, see lligure 5.

in this position of the parts the rearward thrustiinparted to the pivotedroller arm '73 by the swinging upright arm '70 causes the shaft 76 of the roiler 66 to move upwardly and rearwardly along the upper inclined surface 90 of the switch. As the roller shaft encounters the horizontal portion of the switch beyond the bend or curve 87 the roller moves rearwardly in a horizontal direction above the labels and as the shaft passes the pivot 86 which may he seated in a second.

plate 92 secured to the baclr of the first plate, see Figure 1 the switch tips in left handed rotation about the pivot and the shaft moves down the incline into contact with the rearward end portion of the opening 8st at 93. At this point the motion of the crank pm 80 and of the swinging arm 70 is reversed 95 carries the roller over the gage andcnd of label.

The paste pot roller 67 is driven through toothed sprocket 115 on the stud 120, which sprocket is engaged by the chain 1'6 which drives the sprocket 15 on the shaft 11. This sprocket 115 carries a toothed gear 117 which meshes-with a gear 121 on the shaft 116 carrying roller 67. This shaft carries near the paste pot a gear 119. The pick-up pasting roller 66 is proyided on'the end of -its shaft 76 with a gear 118 which in the position of the pasting roller shown in Figure 9 in which it contacts the paste 0 roller 67,:--meshes with the gear 119. 's

provides for the uniform spreading of the paste on the roller'66 when it is in contact with the paste pot roller.

To prevent displacement of the top labels by the action of the roller 66', pressure is ap-v plied to the top of the pack by means of'a presser foot 97, see Figures 15, 16 and 20.

This presser foot is in the form of a bar extending across the top of the label pack at right angles to the-direction of the feed and the length of the machine.-

is due to the weight of the parts though the invention is not limited to this detail. As the picking up of the-labels is dependent on the instantaneous adhesion of the forward ends of the labels to the cans as they pass, the grip of the presser foot if continuously applied might be sufficient to displace the labels or even prevent them from being picked up.- To avoid possible interference with the operation of the machine in this way, means is provided for raising the presser foot to release each label from the presser foot as it is picked up; 98 is pivot ally connected to the presser foot or bar at each end .of the, latter and at each side of the'niachine. The presser foot bar is provided at each. end with an upright or cross head 99 secured thereto. 7 This cross head runs in guides 194- on the frame see Figures 2 and. 15, and to. these cross heads the connecting rods 98 are pivotally connected as aforcsaid.

The connecting rods 98 are connected at their upper ends, see Figure 5, to a swingin. level: 100 pivotally mounted. at 101 at eac i. side on the machine frame and extending forwardly at each side of the ripper portion of the path of the cans. The swinging arms 100 carry the can feeler roller 105?, extending across the path of the canal, to engage the upper portion of the latten This is monntec'l at each end in one of the feeler crime 108 and the connecting rods 98 are pivotally con nected. to the arms at 1 08 forwardly of the roller. Arms 100 also rest on belt presser roller 108. j

The rear ends or lap ends of the iabels are paste coated by means of lap end past/in belt 105 shown in section in Figures an 16 and to be further described. lit is appar- To this end a connecting rod ssh 1n the form shown the pressure thus applied to the labels out from the description that after each can has picked up the front end of the top label and rolled backward over the lap end pastiao ' ing belt which covers the rear ends of the labels, it will contact the

feelers

102 and 108 and raise the resser foot releasing the rear or lap end of the label just as tension is applied to it by the can. To prevent scra ing of the adhesive from the rear or lap on s of the labels as they are drawn from under the presser bar the latter is provided with a succession of notches 106 spaced along its lower surface as shown in Figure 20. By this ar-- rangezhent the paste on the portions of the surface of the lap ends of the labels which register with the notches is undisturbed.

The machine is provided with any usual or suitable curler bar 197. With the full length labels which extend entirely around the can-lapping over at the outer or rear end of the label the normal operation of the curler bar as well understood in the art is entirely satisfactory, but the present inachine is intended lorhuse with short or panel labels as well as with the full length labels. The panel panel labels cover a half or a third of the circumference of the can. Such labels are more easily dislocated or entirely removed from the can by the action of the curler bar. To provide for the use of short or panel labels and to obviate the danger that the labels may be dislocated or removed from the cans. after picking up means is provided in the present machine in connec tion with the presser foot whereby the grip of the curler bar may be released to any ole-- sired degree at the moment of the final withdrawing of the rear end of the label which which the pin. is engaged being passed through a suitable vertical aperture 112 therein, which aperture is suitably threaded for engagement of the threads on the pin. This threaded pin is shown as provided with a suitable knurled head 114: below the bracket" 7 When the short labels are used the pin is turned up into-engagement with the curler bar as shown in Figure 15, the length of the pin being adjusted to give the desired relaxation of the grip of the curler bar, which results in the necessary amount of curling without applying sufficient tension to the label to removeor dislocate it. Figure 16 shows the adjusting pin. 110 withdrawn. so as to provide for the use of the full length the side of the ileiaeao labels With the adjustment shown in Figure 16 the raising of the resser foot does not change or relcasethe grip of the curler bar, the Presser being shown in this connection in raised position. The adjustment in Figure 15 provides for raising of the curler bar simultaneously with the raising of the presser foot. This raising of the curler bar may be deferred and reduced by lowering the pin. This is the extreme adjustment and in operation should be such as to give the desired timing and pressure and hence the right degree of curling of the label as it is withdrawn.

The paste pot roller 67 as shown in Figures 12, 13 and 14- is grooved circumferentially at 123, the grooves being spaced apart in the direction of the length of -the roller. As shown, the spacing is slightly greater than the width of the grooves. The grooves provide for the retention and distribution of the paste and to equalize the paste a scraper or gauge 124.- is supported in, the paste pot adjacent the roller. This scraper or gauge 124 is secured by means of screws 125 to a scraper or gauge supporting plate 127 which is adjustably mounted on an upright 128 in the paste pot. The gauge supporting plate 127 is secured to the upright in the form of the invention shown by means of screws 1 29 seated in theupright 128 and engaging slots 130 in the supporting plate 127.. To provide vfor access to the screws 129 and to permit the same to engage the top of the supporting plate 127 the scraper or gauge 124 is apertured at 131 around the screw and slot. The arrangement of the parts described. provides,- when the screws 12%) are loosened a free adjustment of the gauge carrier or supporting plate 12'? toward and from the paste pot-roller 67. For the purposes of such adjustment the gauge supporting plate is moved by screws 133 having a threaded engagement with suitable bosses 134; located in aste pot and apertured and threaded for this purpose. The screws 133 have a swivel connection at 135 with an upri ht portion 136 of the plate 127 0th pasting mechanisms are denendent on the admission of cans to the machine and i are operated once for each: can so admitted, sothat whenever the supply of cans is discontinued the paste coating operation is also discontinued and he top label remains dry ready to receive a fresh supply of paste whenever the machine is started The mechanism vfor coating the lap end of each label with adhesive is driven from longitudinal shaft 145 which is turn driven, see Figures 1 and l by bevel gears 14:3 and 1414 the latter being connected to a sprocket 140, the bevel gear 143 and the sprocket being connected to rotate together and mounted on the same transverse stud or shaft M1.

I shaft and sleeve;

The sprocket 140 is driven by the previously mentioned chain 16 which runs constantly and drives shaft 11.

The shaft 145 carries a toothed clutch which enters a groove or track1.52 in the clutch member between flanges 153 thereon. is shaft 1&5 also carries a freely rotating lap end paste belt pulley sleeve 155 on which is mounted a .ciutch member having teeth 15'! which cooperate with the teeth 148 of the first mentioned clutch member. This clutch member 156 is keyed to the sleeve 155 by means of a key 158 to rotate therewith and slide in the direction of the axis of the lhe sleeve 155 also carries secured thereto the lapend paste belt drive pulley 159 end a helical spring 1.60 is wrapped around the sleeve between. the said pulley 159 and the clutch member 156 hearing against both said members and tending to thrust the. clutch member 156 into engagement with the clutch member 1 16.v The clutch member 1561 is aiso provided with cam membsr'l with a radial com surface 182 a high point 163, which, in the position. of machine shown in- Figures 2 and 534i, is engaged by a pin 16 1- mou'oted to slide in a bearing mounted on a stationary part of the machine.

The cans are supported in this position by a plate 176 which rests on the ways 7 and leadsthc cans up to the 300, This plate 176 is notched at 179 to admit the end of the arm 1% and the arm is held in raised position siightl; above the plate and. in the path oi the cans by the tension of the era 'ng 1.70 which applies a constant tension to the v fork 11-87 tending to swing it toward the observer in Figure 7 As each can advances over the plate 116 iengage and continue tion of the sleeve 15o after. passing the lap end pasting belt and approaches the pads, it paseesover the end of the lever arm 174 depressing the same and withdrawing the bolt 164 from contact with the cam surface 162, particularly the high point of the same, 163. V

The withdrawal of the belt 164 permits the ciutch'member 156 to move to the leftin Figures 2 and 9A in response to the pressure of the spring 1.60 causing the teeth 157 thereon to come into engagement with the clutch teeth 148 of the clutch member 146 so that the sleeve 155 is locked to the shaft 145 which, as aforesaid, is rotated continuously driven by and from chain 16 through sprocket 14:0 and

bevel gears

143 and 1 14. As soon as the can passes, the pin 164-. is advanced by the spring 170 and contacts the outer surface 162 of the cam. When the low point the cam comes opposite the pin the letter advances to the normal position Figures 2 and 24:, engaging the cam surface and further rotation brings the high point 163 into engagement with the pin releasing the clutch. Stop pin 173 seated in the member 156 engages the pin 164; in the out (Jr-stationary position oi the clutch preventing the parts from being further rotated by the momentum thereofwhichwoul-d carry the high point of the cam by the tolllower pin and would cause the clutch to rethe parts in rotation. The stop and cam control limit each operaand paste belt pulley 159 to a single revolution.

More briefly stated the mechanism just described is a singlo revolution cl .tch controlled by the horizontally sliding pin 16:, the clutch heing engaged by the ection of spring 160 when the pin is withdrawn by the passage oi the can ever the arm 17%1. As

soon as the pin or belt 164- is released after the passage of the can the pin or" bolt turns to engagement with the cam'member and rotation of the cam-member to high point 163 disengages the clutch rotation of which stopped by contact of the pin 173 on the clutch with the horizontal slidin" pin or bolt 1642. The operationol thisciutoh is substantially the same as that of the clotch 18 illustrated in detaii'in Figures end 11.

The illustration, Figure 2, includes paste pot roller 182 whereby the paste is picked up from the pot and applied to the lap end pasting belt 105. This roller is mounted on a shaft 183 to which is secured a sprocket 184 driven by a chain 185 from a sprocket 186 secured to the lapend paste belt pulley sleeve 155, carried by the lap end pasting shaft 145. The construction and operation of the lap end paste coating mechanism, so far as this detail is concerned and other details not relating to the intermittent drive, is similar to generally known prior art structures understood by those skilled in the construction and operation of such machines.

A feature of interest 'in connection with ,the operation of the present device is the belt .presser 190, Fi ures 21 and 2. The same consists of two levers, one at eachside of the ways, the pivots 191 being carried by suitable brackets 192. These belt p'ressers are well known. They rest on and are sup ported by the belt projecting slightly above the can supporting surface of the ways. As

' each can passes they are engaged from above by the can and pressed downward against, the belt which is in turn pressed against the lap end of the label. As each can asses from the label table, as foresaid, the 'ap end paste belt 0 crating mechanism is tripped and operated imparting to the lap end pastebelt pulley 159 a single rotation advancing the paste belt a corresponding distance bringing a newly paste coated portion of the belt over the top label on the table; I

As the cans orpackages, each bearing a newly pasted label, pass from the lap end pasting mechanism rolling across the plate 176, they encounter the

pads

200 and 201 which are spaced and located corresponding tojthe location and spacing of the ends of the labels These pads are preferably of sponge rubber or other extremely resilient material. The ads servejto flatten the labels against the sur ace of each can, particularly at the ends where they are coated with adhesive, the pads being so spaced where panel labelsare used as to engage the pick up and lap end POItlOIlSrOf the label respectively, so that as it passes, the can is supported on and. between the pads applying tension to the labels from the center toward the ends. T he pads are movable and adjustable in the direction of the length of the ways, as hereinatter described, and where a full length label is used extending entirely around the can, the pads may be placed in contact with each other or a single pad may be used. The adjustment provides for variation in length of the panel labels, making it possible under all circumstances where labels of dillerent lengths are used to so place the pads as to cause them to register with the respective end portions Between the pads 201 and 'tically in alignment with the ways.

lifting mechanism already described. labels are thus left clean, uncoated and ready the pads so that the top surface of the pads is higher than the adjacent supporting surface and the pads project into the path of 'the cans or packages. These blocks may be of any suitable material either similar to the pads or of less resilience. In the form of the invention shown the

pads

200 and 201 and the intermediate and end blocks 203 are supported on angle irons 204 which are prag- T e blocks are preferably cut to fit in the angles and may be arranged thereon to give the desired spacing, the intermediate block 203 and the end blocks 205 being removed to provide for the free spacingof the pads 201 and 202 after which the area, if any, between the ads and at the ends of the pads is filled in by suitable blocks 203. In addition to the normal function of flattening the ends of the-labels against the cans, the resilient pads also serve to enter the irre ularities and the holes in the cans, which result from various causes. These are sometimes due to blows or bumps which the cans receive and to the existence of a vacuum in the cans as a result of the canning process, which permits the cans to collapse to a greater or less de 'reein response to atmosfiy this means the labels are brought into close contact and caused to adhere closely even when the surface is irregular and. depressed, as described. 7

The cans are spaced by the gate 43 a distance a little greater than the length of the labels and as each can is admitted it trips the pick-up paste or cement coating mechanism which imparts a single stroke to the roller 66, which is normally in contact with the paste pot roller 67, passing it upward, backward, dropping it on the top label and bringing it forward. in contact with the for-- ward end of the label. As the same can passes backward through the machine over the top label on the table it encounters thebelt presser 190 over the lap end paste coat-- ing belt, a newly coated portion of which has just been advanced by the action of the previous can, as aforesaid, pressing said newly coated portion of the belt downward against the top label on the pack. The can passes out of contact with the belt presser before the lap end of the label is withdrawn from beneath the bolt the prcsser bar and the label curler, the grip of which latter two members is released by theaction of the The.

to receive the paste on the admission of a can and the coating mechanism remains in-- operative whenever the feeding of cans is interrupted for a short or long period so that drying of paste on the top label and till llll) accumulation of an excess-of paste due to intermittent feeding is avoided, as" is also loss ofpower due to continued operation of the mechanism during interruptions of the can feed, the machine being thus rendered wholly automatic.

The paste coating mechanism being completely controlled by the cans, Supervision of the machine in operation is almost entirely dispensed with, the greatest possible economy of power used in the operation of the paste coating appliances is effected, and. the machine is made available for use where it previously could not be used economically on account of the? intermittent supply of cans or packages and the necessity for supervision, and the economy of. operation .under the circumstances is greatlyincreased.

l have thus described specifically and in detail a single embodiment of my invention in orderthat the nature and operation of the same may be clearly understood, however, the specific terms herein are used in a descriptive rather than in a limitin sense, the scope of the invention being de ned in the claims.
