To all whom, it may concern:
Be'it-known that I, M'An'rrNFEYBUsoH, a
citizen of the German Empire,' and a resident of Sea Cliff, in the county of Nassau and. State of New York, haveinvented certain new and useful Improvementsin Machines .for Goatin Labels and Similar Ar ticles with Adhesive, of which the followin is a specification.
his invention relates to a machine of novel construction for providing the backs of labelsand similar articles with an adhesive coating so'that the labels are ready for attachment to their bases by means'of additional machines, with which the ma.- chine which forms the subject matter of the present invention, is designed to cooperate. The machine is also applicable to blanks that go to form paper boxes or parts thereof, and to various other articles which are to be covered by an adhesive on one of their sides.
Briefly stated, the labels to be coated are stacked within an adjustable magazine, their forward edges being brought into engagement with a rubber-covered roller,
. which is fixed. This roller serves'not as a conveyer, but as an abutment, against which the labels are feathered out by meansof a series of feed tapes that constitute the bot- 'tom of' the magazine. ,These feed tapes carry the successive bottom labels from under the fixed roller, and thus out of the magazine, to be engaged by a second series of feed tapes which are operable either in conjunction with or independently of the first series. The second series of tapes in turn conveys the labels beneath a pair of conveying rollers and under a tension blade to a paste applying roller, to the periphery of which they are held so as to become coated in the manner desired. The coatedlabels are stripped off this roller by a number of pick ofi's which turn the labels over and conduct them, bottom upward, upon a conveyer belt. On this belt, they are subjected to the action of a number of pressure de-. eeling, and.
. the specification and appended claims.

Fig. 2, a right hand side elevation;
gummed- This magazine is formed of a pair of side plates 3, mounted on a transverse shaft 4, along which they are adjustable so that the magazine may be set to labels of different widths. The bottom'of the magered by rubber jacket 11 and constitutes a cylindrical abutment for the labels. The shaft of this roller engages slotted arms 12 of the machine frame, along which it may be vertically adjusted by coned screws 13, so that in this way, the clearance between the roller and the feed tapes may be set to labels of different thicknesses. In order to adapt the magazine for the reception of labels which are longer than tape 5, frame 1, is provided with a rearwardly extending longitudinally adjustable bracket 14: in whi'c is mounted, a vertically adjustable shaft 15. On this shaft are mounted, a plurality of laterally adjustable clamps 16, carrying fingers v 17,. the front ends of which are adapted to rest "upon one of the idlers 8 intermediate tapes 5, while their rear ends extend a considerable distance back of frame 1. \Vhen a pile'of labels is placed upon the fingers, it will, by the forward portions of the feed tapes, be carried against the fixed cylindrical abutment 10 by means of which the label .are, feathered out, insuch a manner that the forward edge of the pile is concaved and that the bottom label only will be fed out of the magazine by the feed tapes. The latter convey the label thus withdrawn from the magazine, upon a second set of parallel belt or feed tapes 18- that advance it on its way toward the adhesive-receiving means hereinafter referred to.
Tapes 18 pass over front feed roll 19 and a rear feed roll 20, the latter being spaced a short distance beyond front roll 6, of the first set of tapes 5. Between rolls 19, 20 there are arranged, a number of idlers 21, one of which is flanged as at 22, while above the tapes are mounted in the machine frame a number of pressure rolls 23, that serve to hold the labels to the tapes, during their travel along the latter. The object of providing two independent sets of feed tapes, is to permit either both sets. to be operated simultaneously (which is the normal condition) or the advance set 18 to be driven, while the rear set 5 is at rest. This stopping of the rear tapes should take place when the magazine is empty in order to then prevent an abrasion of the rubber jacket 11 by the moving tapes 5 while the continued motion of the front tapes, will carry the train of labels last released to the gumming mechanism.
The means for driving the tapes are shown to be as follows: Power shaft 24 by coned pulley 25, belt 26, and coned pulley 27, drives acounter shaft 28. The latter, by pulley 29 and belt 30 drives a disk or ulley 31, that may be coupled to the main drive shaft 32 by a clutch 33 (Figs. 1( )12). The clutch may be opened or closed from thefront of the machine by a handle34 (Fig. fast on an upright rock shaft 35 having a finger 36, that engages a groove 37 in the hub of clutch 33.
Shaft 32 by chain drive 38, turns a stub I shaft 39 having a long gear wheel 40, in
which meshes a pinion 41 fast on feed roll 20 and also a pinion 42 of a clutch 43 (Figs. 6-8) adapted to be coupled to feed roll 6. Clutch 43 is operated from a rock shaft 44 by link 45, connecting rod 46, link 47, upright shaft 48 and finger 49, so that when the clutch is thrown in, both sets of feed tapes are operated by pinions 41, 42 while when the clutch is thrown out by the turning of shaft 44, the front set only is operated by pinion 41.
Rock shaft 44 is also axially slidable and at 53, integeared with shaft 32.
stop the rear feed only, while' by sliding it he may stop the entire machine.
The front feed tapes 18 carry the labels toward and between a pair of intergeared feed roll 51, 52 the lower one of which is From rolls 51, 52 the label passes underneath the lower edge of a tension blade 54 that serves to deflect thelabel toward the face of an adhesive applying roller 55, which is vertically adjustable and contacts witha paste receiving roller 56 dipping into a pan or receiver.57 containing an adhesive, such glue. or paste. Roller 56 i at 58 intergeared with feed roll 52 and is in turn at 59, intergeared with paste applying roller 55, ,so that rollers 55 and 56 turn in opposite directions.
To the front of the machine, there is fulcrumed at 60, a bracket 61 in which is journaled, a shaft 62 intergeared at 63 with roller 55 and arranged, a slight distance abovethe same so as tohold the labels against the latter. Over shaft 62, passes an endless conveyer belt 64 to which the labels are transferred with their backs up from roller 55 by means of a number of pick-offs or strippers 65. The latter are secured to arms 67 that turn on a shaft 66 hung inbracket 61 in advance of shaft 62 and are made in the form of concaved jaws which strip the labels ofl' roller 55 after having remained in contact therewith for some time and turn them upward and backward in substantial concentricity to the periphery of shaft 62 which thev partly encompass at the turn of the conveyer belt. The conveyer belt 64 passes from shaft 62 over idlers 68, 69, 70, idler 69 being located at such a distance back of the machine as to carry the procession of gummed labels to the labeling" or other machine with which the presentv machine is designed to coiiperate.
Bracket 61 carries above the upper run of belt 64, a number of shafts 71 from which depend hangers 72, in which are journaled pressure rolls or disks 73. Hangers 72 are longitudinally adjustable along their shafts, so that the pressure rolls may beset over the labels as the latter are carried out of the machine, and prevent the same from peeling off the conveyer.
By slacking a pair of clamp screws 74 bracket 61 together with its rollers and other adjuncts may be swung into a horizontal position (dottedlines Fig.1) so as to carry pick-ofi's 65 away from roller 55, and permit all the parts to be readily inspected, re moved, cleaned or repaired.
The operation of the machine will be readily apparent from the foregoing description.
A stack of labels is placed in the magazine, and by the operation of the rear feed tapes such stack is forced against the rubber jacket 11 of the fixed roll which thus constitutes an abutment by means of which the labels are feathered out. The successive lowermost labels are transferred by the rear tapes 5, to the front tapes 18, which in turn convey them, beneath blade 54, to the face of the paste applying roller 55 that covers their backs with the adhesive. Pick-offs 65 then strip the labels ofl roller 55, and turn them toward shaft 62, so that in this way,
, the labels are reversed and are transferred back upward to the conveyer 64. The latter carries the labels to the labeling, box,
making or other machine for further treatment.
The machine is readily adjustable to labels of various dimensions and configuration, feathers them out neatly, and carries them in a uniform procession to the paste applying means and thence to the conveyer. Should the operator of the machine with which the present machine is intended to coiiperate, see that the magazine is empty,he throws out clutch 43, by means of rock shaft "44,
which is within his reach, and thus arrests the rear feed tapes while the remainder of the machine retainsits motion, so that the labels that have left the magazine will continue their travel toward the paste applying device and thence to the conveyer belt that keeps on moving and carries them to their destination.
