12 Claims.

This invention relates to improvements in machines for delivering labels, more particularly of the type in which a label coming from a printed strip is cut to a predetermined length and delivered with a moistened gum thereon ready for application to a container or the like.

One of the objects of the present invention is to provide a simple and rugged construction for such a mechanism whereby the label strip is advanced the required distance and then a severing means is operated to sever a label of the predetermined size by a continued movement of the operating mechanism.

Another object of the present invention is to provide means whereby the feeding mechanism may be adjusted to labels of different lengths, quickly and easily, and whereby any accumulating errors may be compensated accurately.

A further object of the present invention is the provision of means for releasing an oper-' ating handle from the advancing mechanism after the completion of a predetermined stroke of the latter, whereby the operating handle may drive the severing means without further operation of the advancing mechanism.

With these and other objects in view, as will appear in the course of the following specification and the drawings, an illustrative form of construction of a machine according to the present invention is set forth on the accompanying drawings in which:

Fig. 1 is a right hand side elevation of the machine;

Fig. 2 is a top plan view of the same;

Fig. 3 is an end elevation;

Fig. 4 is' a sectional view on line '4, 4 of Fig. 2;

Fig. 5 is a fragmentary sectional view substan-' tially on line 5, 5 of Fig. 2;

Fig. 6 is a fragmentary elevation of the left hand side of the machine.

Fig. 7 is a sectional view through the clutch.

Fig. 8 is a sectional view on line 88 of .Fig. 9,

of a modified form of construction of the feeding rollers and associated parts.

Fig. 9 is a sectional view on line 9-9 of Fig. 8. Fig. 10 is a plan view of a guide shield. Fig. 11 is a plan view of the modified form. In the illustrated form of the machine a handle is provided with means whereby a'forward and downward movement of the handle causes an advancement of the label stripby a distance equal to the length of an individual label, followed by a disengagement of the handle fromthe feeding mechanism whereby the handle is enabled to operate a severing means without furing of the label strip is assured by pressure rollers and means are provided for relieving they rollers while inserting or adjusting the label strip. A moistening device is provided in close proximity tothe severing means and as a guide incorporated therewith so that the end of the label strip is carried forward into engagement with the moistening means or similar device for assuring that the label has a layer of gum ready for attachment to a container or the like.

In the drawings the side frame members 10, 11 are held at the proper spaced intervals by the connecting bolt-pillar assemblies 12, 13. On the upper edges of these side members 10, 11 are provided guides 14 providing bearings for the reduced ends 15 of the label supply'shaft 16 which has the centering cones l7 thereon, for supporting the roll 18 of printed, etc., labels in strip form.

These frame members likewise carry the upper feeding roll shaft 20 which is mounted on a fixed axis therein, and has the enlarged central portion 21 operating as an upper feed roll. Crank arms 22 are pivotally mounted by pin 23 in these side frames and have the arms 24 which extend substantially horizontally and receive the reduced stub ends 25 of the lower feeding roll 26, this roll and its stub ends being located wholly between the inner faces of the side plates so that it is free to be moved up and down. The downwardly extending arms 27 of the cranks are joined together, by a web 28 extending transversely of the machine and adapted for engagement by the arcuately bent relieving shaft 29 which is journaled in the side plates and is provided exteriorly of the machine with a radially directed end 30 which passes through an aperture of the clip 31 on the side plate 11 and is normally forced downward by a compression' spring 32 which may be adjusted by the screw 33.

The upper supply roll 21 has itsshaft 20 extended through the right hand side plate, and loosely carries a gear 34 on the outside of the said plate. This gear is assembled rigidly with a clutch drum 35 having a plurality of dogs 36 located therein and engaged at their inner ends in grooves 37 of the shaft end 20. Each. of these dogs has a spring and clamp member 38 engaging with the shaft to hold the respective dog in its proper position. An end plate 39 is secured to the shaft by the clamping nut 40 which is threadedly engaged with the end of shaft 20.

The master circular rack 45 is provided with a plurality of teeth and is always in mesh with the gear 34. The master rack 45 has a radially outwardly projecting stop finger 46 to limit its movement as will be described more in detail hereafter. This master rack 45 also has an axially projecting pin 47 on its periphery.- This master rack is loosely mounted on a shaft 48 which extends through the side plates 10, 11 and is journaled therein for accurate rotative movement, the left hand end of this shaft 48 being held by a clamping collar 49. Fixed to the right hand end of this shaft 48 is the hub 50, carrying a radially projecting arm 51 formed integral with the handle portion 52 extending substantially at right angles thereto and terminating in the operating handle 53 proper. A pawl member 54 is mounted on a pivot pin 55 fixed in the handle lever 51, 52, and is engaged by a coil spring 56 secured to this handle lever so that it is held in engagement with the pin 47 and thus obliges the master rack 45 to move with the operating handle 53 so long as only the normal resistance of feeding the label strip is opposed to such movement.

Loosely mounted on the shaft 48 is a radial arm 60 having a rebent end 61. A threaded member 62 joins the arm 60 with its rebent portion 61 and receives outside of the portion 61 a clamping thumb nut 63. When the thumb nut 63 is tightened down, the master rack gear 45 is clamped between the arm 60 and its rebent portion 61 so that the arm 60 is held rigid with the master rack 45. The radial arm 60 also has a portion 64 struck up therefrom to provide a strike plate to engage the end of the tangentially arranged micrometer adjusting screw 65 which is journaled at its cylindrical portion in a lug 66 of the side plate 10 and is engaged at its threaded portion with an internally threaded lug 67. The free end of the micrometer screw 65 carries the adjusting thumb piece 68.

Between the side plates 10, 11 the shaft 20 and its feed roll 21 is provided with a gear 69 normally in mesh with a gear '70 on one stub shaft 25 and its feed roll 24 so that movements are transmitted between the gears and shafts. The left hand end of the shaft 20 is provided with a thumb wheel 71 whereby this shaft may be moved by hand if so desired. 1

The ticket severing device comprises a stationary lower knife and a movable upper knife 81 having a cutting edge in the form of a fiat inverted V. The upper movable knife rests against a guide plate 82 secured upward to the extensions of the side plates 10, 11 by the screws 83. A pin 84 fixed in the upper knife receives the lower end of an obliquely upwardly and rearwardly extending tension coil spring 85 whose upper end is engaged by a pin 86 carried on the fixed frame plate 82, so that this spring holds the upper knife 81 in engagement with the guide plate 82 and also returns the upper knife after it has been moved downward to sever a label.

A severing shaft 87 is journaled in the side plates 10, 11 of the machine and has a radial extension 88 at the right hand side of the machine, which terminates in an axial crank pin 89' (Fig. 3). Fixed to the shaft 8'7 between the side plates 10, 11 are a pair of crank arms 90 which extend through slots 91 in the guide plate 82 and fit closely in apertures of the upper movable knife 81 (Fig. 3). The two crank arms 90 are preferably joined by a central web 92 for greater strength,

and the projecting ends of these arms may be provided with small pins 93 in front of the movable knife 81 to prevent accidental displacement of this knife without the prior removal of the pins.

The handle lever 51, 52 is provided with an offset and axially extending finger 94 which during the movement of the operating crank handle 53 is brought into contact with the axial crank pin 89 of the severing means.

It is usual to provide a supply 18 of labels in strip form having printing on one side, being the upper or outer side in the drawings, "While the lower or inner side of the strip is coated with gum. It is preferred to provide means of moistening such gum or for placing a coating of gum upon the lower side of an uncoated label. For this purpose a liquid tank is provided with laterally extending arms 101 having apertures to receive the reduced threaded portions of the clamp screws 102 which are threadedly engaged in the upper surfaces of ledges 103 on the side plates 10, 11. A wick or brush 104 in the liquids tank passes through a top aperture of the same and is presented for engagement by the end label L (Fig. 1) of the label strip. A guide member 105 is pivotally mounted on the liquids tank, and has its inner end rounded upwardly and carried opposite the inwardly turned end 82a of the end plate 82, so that as a label is fed forward by the supply rolls 21, 24, this label is forced between the cover IOU 105 and the top of the liquids tank, and is thereby brought into engagement with the brush 104. A guide clip 106 is secured around the lower knife 80 and is located opposite the upper guide 82a.

The method of operation of this mechanism is as follows:

A roll 18 comprising a strip of labels of any desired width and having a certain predetermined length for the individual labels is placed on the locating cones 1'7 and the shaft 16 passed therethrough and dropped into the bearing brackets 14. The guide arms 99 are then adjusted into guiding relationship with the faces of the rolls (Fig. 2) by releasing the clamping nuts 98 at their ends and sliding the rods along the slotted guide channel 98a until they are in the proper position and then tightening them again. This guide channel fits around the flanges 99a on the respective rods 99, and itself is supported by the bent ends 99b which are pivotally mounted by bolts 990 in the face plates 10, 11. It is preferred to center the label strip in the machine during this adjusting operation.

To regulate the machine in case a different predetermined length of individual label is to be delivered and cut, the moistener box or tank 100 is removed. The label strip is drawn out and fed forward between the supply rolls 21, 25 by rotating the thumb wheel 71 until three label lengths have passed through. The exposed part of the strip is then split and one side is torn off. The clamp nut 63 is released. The releasing lever 30 is raised so that the lower roll 25 freesthe strip.

The handle 53 is now drawn forwardly until the finger 46 is in close engagement with the stop bar 110, while the spring pawl 54 is yet engaged with the pin 4'! as this latter detail is shown in Fig. 1. The arm 60 is swung downward until the plate 64 is against the micrometer plate 65. The label strip'is now moved until the proper line for severing is flush with the cutting edges of the knives 80. 81, and then the lever 30 is released. The thumb Wheel 71 is now rotated so that the handle 53 and the master rack gear 45 are moved backwardly until the other cutting edge of the label which has thus been moved backward in the machine is brought opposite the knives 80, 81. During this movement the plate 64 has been retained by the end of the micrometer screw 65, while the master rack 45 has been free to move between the portions 60, 61 of the radial arm supporting the clamping nut 63. When the full length of the label has been fed backward in the machine, the movement of the thumb wheel 71 is discontinued and the clamping nut 63 is tightened. The machine is now adjusted for theproper distance for the cutting. It is obvious that any predetermined corresponding portions of two labels may be employedfor regulating the machine, and thereafter the label strip may be moved upon raising the lever 30 so that the proper portion of the label strip comes between the knives for severing.

With the machine thus adjusted, the moistening box is replaced.

To employ the machine, the operator stands in front of the left hand end of the machine in Fig. 1, which has been referred to as the front of the machine. The handle 53 is drawn forward, so that the spring pawl 54 carries the pin 47 with it and thereby rotates the master rack 45 in a counter-clockwise direction until the radially projecting finger 46 encounters the stop bar 110, and the master rack 45 is prevented from further forward movement. During this movement of the master rack 45, however, its gear teeth have been in mesh with the gear 34 on the shaft 20 and have caused a rotation of this shaft and therewith of the upper supply roll 21, in a clockwise direction in Fig. 1. The gears 69 and '70 are likewise in mesh and hence the lower supply roll 25 is driven in the opposite direction while in pressing contact with the label strip, which is thus advanced through a distance determined by the movement of the master rack prior to the engagement of finger 46 with the stop bar 110.

When the finger 46 engages and thus arrests I the master rack 45, the spring pawl 54 is released from the pin 47 by the continued forward movement of the handle 53. The handle lever 51, 52 is therefore free to make a further movement until its projecting portion 94 engages the end 89 of the severing mechanism and causes a counterclockwise movement of the shaft 87 thereof in Fig. 1. This results in a downward movement of the ends of the crank arms 90, and therewith a downward movement of the upper movable knife 81 against the action of the return spring 85, until this knife has severed a label from the strip, bycooperation with the lower knife 80.

During the forward movement of the label strip, its end has beenvforced between the cover.

105 and the internal guides 100a of the moistening box 100, and its lower side has been brought into engagement with the moistening brush 104, so-that upon the completion of the severing movement, a label is presented ready for application to a container, being momentarily held by the engagement of the brush 104 with its lower side and the cover 105 with its upper side.

The operator now pushes the handle 53 backward away from himself, so that the handle lever attained by the slight continued .movement of this handle lever after the master rack has been stopped.

The continued reciprocation of the handle 54 results for each cycle in the delivery, moistening, and severing of a single label of the proper length from the label strip.

The adjustment thus attainable on the master rack 45 by releasing and retightening the clamping screw 63 may lead to slight accumulating errors. This, however, may be compensated and such errors are eliminated by adjustment of the hand wheel 68 of the micrometer screw 65 which regulates the position of arrest of the plate 64.

During the initial return movement of the handle lever 51, 52, the spring operates to move the knife 81 upwardly, and therewith restores the crankpin end 89 of the severing shaft 87 to its proper position.

A particular feature is the provision on the stop bar 110 of a brake shoe 115 for engagement with the upper supply roll 21. This stop bar is held in position by a screw 116 passing through its other end. A coil spring 117 is located between the head of this screw and the bar 110 to hold this bar in position so that a slight retard-.

In the modified form of construction shown I in Figs. 8 to 11, the upper cylinder roll is replaced by a pair of rolls 21a, spaced apart and preferably formed integrally with the shaft 21b which carries the drum 39 of the clutch device, the drivinggear 34 and the gear 69, as well as a brake drum 21c which is of greater diameter than the shaft. This shaft 21b also carries the hand wheel '71 by which the shaft may be revolved for manual adjustment.

The lower shaft 23 likewise carries a pair of narrow drums 26a which are separated by a central groove. This shaft 23 carries the gear '70 in mesh with gear 69 and is supported by the crank arms 26.

The upper or movable knife 81 is provided as 120 guide the edges of wide labels. The tongue 122 and the wings 123 are curved relatively upwardly to facilitate the entry of the end of a label strip.

A similar guide plate 124, having the downwardly curved central. tongue 25 and side wings, is provided, with cut away portions to receive the lower rolls 26a, 26a. The stop bar has a brake shoe as before, provided with a leather facing 115a and cooperates with the grooved I brake drum 210.

This modified form of construction is designed to avoid any creeping or false movement of the label strip as a result -of inertia. For this purpose it is preferred to form the narrow rolls 21a, l I

26a, of aluminum. The operation is the sam as before.

It is obvious that the invention may be employed in many other ways than that specifically illustrated and disclosed without departing from the scope of the appended claims.
