Application "filed nareii 1 1924. Serial. no. (#96328.-

This invention relates to la beling inachine of the type in which cylindricalartic'les to be labeled, or at-leastarticles that can be rolled along a path, are labeled as they} are advanced.

The principal objects of the invent-ionare to provide an improved way ofadvancing each rolling article into a position to receive "a label onits surface; to provide positively operating meansfor rotating the article on a stationary axis while the. label is being applied and also to provide'the labelholder with means for giving-it an irregular cir-. cular or orbital motion as the label is being taken therefrom and gummed by the gum-1 ming roll and advanced to a POSltiOIl' to come into'contact with the article to be labeled.

. The invention also 7 involves improvements in the details of-themechanism for accomplishing these objects and advantages of the invention will appear below.

On the shaft 12' there'is a gear 15 which.

througha gear 9, operates a gearlfi'on a} shatt 17 parallel with the pqwe shart. This shaft 17 carries a.

gum; roll 18 operating-"in gum box can be used. "The gum oradhesiive roller 20 which rotatesgby friction witht n p by the roll ls'and delivered. tpf -i ggum roll 18 and also with a gum carrying .member inthe form ofa drum21 positively fixed o'n'the main shaftfi12f The rol1,20

surfaceis atleast'equal to the circumference of one of the cans orother articles tobe is a contact plate 26. This plate is providedwith a series of slots 27 in its surface and it the drum. The parts of the plate between thegrooves are arranged alternately with the grooves in the drum and tangent thereto so that the labels will be guided into close con tact with the gummed drum. Although the surfaces'of these two members do not touch,

they force the label into a position to re p r can be instantly stopped by withdrawing the ceive gum throughout their length.

Also mounted on two cross rods 28 and 29 is a. comb 30. This comb is provided with slots which separate the teeth .31 from each othera These teeth are spaced apart the same distance as the grooves on the drum 2] and.

the comb is so located as to peel the label ofi the'drum and guide it over roll 32;,directly in contact with the rotating can or other article to be labeled as it is beingfed along by the drum as shown in Fig. 6. Meshing with the gear 15 isa gear 35 which drives I 'flat upper surface which supports a roll 65 on a gear .36 which in turn drives a gear 37 on ome shaft 33.. This gear 37 meshes with a gear 38 on av short shaft .39 and drives a gear 40; on the other shaft 33. The gears 37 and 40 are the same sizeso that the two rolls 32 are driven at the same surface speed. They operate to rotate the can in. the position A. Gear157 keyed on clutch. sleeve 56 meshes with large gear: 105 on stud 106. This gear 105 meshes with gear 41 of the same size on short shaft 42 which drives a shaft 413' throu'gth gear 104. r

On the sha 43 are three cams 44, 440 and 45. The cam 44 operates a roll 46 on a lever 47 pivoted on across shaft 48 againsta spring .49. ,On the end of this lever 47 there ispivoted another lever 50 which has a cam roll 51 engaging the surface of the cam which operates it againstthe action of a spring 51. On the lever there is a plate 52 which by the actionof the two canis44 and 45 is given an orbital or elliptical moson, as indicated by the series of, arrows 53.

Pivoted ,On the shaft 48 aretwo arms 54 which constitute a frame provided at theend witha freely rotatableroll 55. This frame has a roll 46%.resting on the cam 440 to give it a motion between the full line and the dotted line positions shown in Fig. 6. The rolls 32 and 55 are all alike .of rubber and 0f the same size. The rolls 32 are geared to run at a slightlygreater surface speed than the gumming drum 21 whichis feeding the label along, and consequently have a ten dency to stretch the label slightly so as tof draw and press it very firmly on to. the can, .leaving no wrinkles, air pockets or blisters.

On shaft 1 2, just inside of, drive gear 15 is a clutch sleeve 56 extending over to. a.

clutch hub 57 which is keyedtoshaft 12 next not being of novel construction need not be fully described. The object of this is to allow the clutch bolt 59 to enter the clutch hub,57 so that said sleeve with gear .and cams on same will be putin motion. That starts the label feeding and the can feeding mechanisms into full operation. The same clutch bolt from the clutch hub by the oppo site movement of the hand'lever at the will ofthe operator.

Mounted on the main shaft 12 there is a clutch sleeve 56 on which are keyed lifter cam 60 and pusher cam 71.

hung on a cross pivot shaft 63. i This frame 62 is bowed upwardly around the elements onthe shaft 12 and extends down at the rear thereof and terminates in a toe 6 1 having a the cradle 66. v This cradle is pivoted. on a Cam 60 opcrates a roll 61 freely rotatable on a frame 62- shaft 67 carried by a pair of arms 68 piv oted on cross shafts 69. One of them is held yieldingly forward by a spring 70 connected withitg r I V The cradle frame for the labelholding device and it is capable of a motion in an irregularly curved path or orbit at its front end. That end is raised and lowered by thB CELITl 60 as ex plained above.

Pusher camf71 keyed. on clutclrsleeve 56 66 constitutes. a supporting engages and operates back and forth horizontally a roll 72. .This roll is freely rotatable on a stud on the front end of a supportng frame 7 3 for the cradle 66. This frame is Thus the arms 75 and 68 swing together to forward and back to the skeleton frame 73. The cradle 66 has to partake of the to-and' is raised. and loweredby means of the can't 60.7 As the two cams that cause these two mot ons are on the samesleeve the niotion of the endv of the cradle will be uniform during each revolutionand will be in an irivoted on the shaft 67 and at its front one on studs 7 6. These studs 76 are mounts .ed on, pivoted arms 7 5' about as long as the arms 68 and pivotedat 77 on housing 78.

fro motion of the frame 73 but its front end 7 this plate is a spring 96 adapted to engage. a,

to move. This lever is connected with-a caslng 84 in which is a spring-pressed sliding pawl 85 adapted to engage a ratchet wheel 86 and turn it through the space of one tooth r if desired every time the lever oscillates This ratchet wheel'is located on a screw-shaft 87 extending longitudinally with respect to the cradle. This screw, therefore, is turned through part oflarotation every time the cradle moves back and forth. It passes through a nut 88 which is formed of two parts having finger pieces 89 projecting from them adapted to be held together by a spring. The two parts of the nut are pivoted on a bolt 90 which is supported by the label follower base 91 of the label holder. There fore, the rotation of the shaft feeds this follower andthe labels alongstep by step toward the drum or cylinder 21.

the label holder 92. This label holder'need not be described in-full, but two side walls are adapted to be adjusted toward each other by a right and left hand screw 93 operated by hand wheel 94 on it. The screw passes through nuts connected to the sides of the frame so that :the sides can be adjusted toward and from each other for labels of diflerentwidths. r V p I Located on the front of the labelholder is a cross bar 93 from'which depends a 'sheet metal guard plate. 94 'haviug spaced teeth 95 at the. bottom. Extending from rod 97 and press'the plate yieldingly against the labels, the object of which is to exert'a gentle pressure against the front or exposed label so as to overcome any tendency for it to sag, also .to prevent a second label belng 1 slightly drawn down while the front label is being drawn away from the rest of the pack by the drum, at the instant when thelabel holder ceases to travel downward at the same speed as the front" label is being moved by the drum. The object of the slots and teeth on the lower endof this plate is to "allow-it to press into the grooves in the drum beyond 7 the surface of same so as not to interfere with the proper gumming of the label The labels stand in an inclined position,

the bottom endsresting on a plate or fioorof the holderat right angles with each other.

with portions of said plate extending out in front of the labels. This plate is provided with one'or more sharp,,thin,- knife points, projecting sli htly upwardly, from same at a slight distance in front of the labels for the purpose of preventing a second label following the one being taken from the holder by the drum;

In the modification shown in Fig. 12 a different means is illustrated for guidingthe. cansor bottles away from the rolls In thiscase an endless belt 100 is arranged to support thecans and there is a' guide 101 On cradle 66 are located the side walls ofabove it with a softer yielding surface 102 toengage the .tops'of the 'cans or the like i This is a substitute forthe form shown in Fig. 2, for example, and I prefer to use it in practiceuas it gives the labels 'an'additional pressure after being rolled onby' the pressure rolls; p

Operation.

The gum boa having been supplied with gum and a packet labels properly adjusted inst-he label holder and the feed chute supplied with cans'to be labeled, the motor is switched on. The gummingrolls and drum are thus set fin'motion, and allowed to run until the operator has-properly adjusted the gumming mechanismso that j ust the desired amount of gum is being applied to the drum. Then the clutch bolt is thrown in by a simple movement of the hand lever, and the machine is then in full operation. The label holderadvances'in a forward and down-,

ward movement, bringing the bottom of the foremost label in contact with the advanced ends of the circumferential ribs of the drum.- Then the drum and label holder move along together for a space of two inches more or less, while the end of'the first label, which attached to the gummed' surface of the j drum, has been'movedaway fromthe pack past the sharp edged obstructionsin the end ofthe label holder near the front of the pack i for the purpose of preventing-more than one i label to-hmoveout of the holder at'a time. Then the .label holdersta-rts to recede slight-' ly from contact with the drum,;leavinglthe front label freeto be drawn out of" the holder. Then the detached label is being moved along between the upper surface of. v

t-he contact plate and the drum to thecomb where it lsi removed from the drum, and

guided into contact with the articleto be:

labelled, as shown in 6. Thellabel holder continues to move in itsirregularly curved path until it brings another label in contact with the drum and soon, until the operator throws the clutchbolt out which will.immediately-bring the label, andthe' can feeding mechanisms to a stop.

In order that the pack of labels i holder may be always in position, so that the against the drumas'hard as desired. The springon the pawl-will yield so that. the

operation of the mechanism takes place just at the time when the labels have fully conthe labels are sure of always getting just the desired pressure against the drum. This tacted with the drum, and finishes the operation before the label holder begins to 'recede from the drum on its backward movement.

7 As will be readily understood by the above; description, the machine is fully automatic,

the label holder forward a very slight di tance. The number of teeth on this, ratchet wheel 86 and the'other parts are so proportioned that this feed will be substantially the same as the thickness of the label. When it is desired to oraw back the frame 91 and reset the parts to take a new stack of labels the two finger pieces on the half nuts 89 will be forced apart, then the whole thingcan be slipped down the screw to a new position.
