scribed and then s ifi lly set forth in the The invention therefore is not to be restricted to Claims hereunto appended the specific construction shown and described. In the accompanying drawings which form a Referrmgto the drawings, the stamps or labels n S are stacked in a magazine I0, which has a part of th1s specification, and in Whlch like chaiplate I I partially closing. its bottom and acters of reference indicate the same or like parts: Venting the Stamps from falling out The provided with a no-package no-stamp mechasupports a t 3 n which is pivotauy mount nism; A L I ed an arm M. The arm 14 carries an air port I e- 2 1s a front elevation of the applymg (16- I5, connected by a hose IS with a pipe (not vice from line 22 of Fig. 1; shown) which connects to a suction pump of any 55. F 3 is a fragmentary p V ew f t p ste well known construction. The arm l4 also car- 0 1 is an end View of the applying device azine Ii] is carried by a bracket 12, which also ries a stud on which is mounted a cam roller ll engaging with a revolving cam 53 fixed on the transfer wheel shaft 32, thereby imparting to the ends of the suction pipes l9, attached to the air port i5 and communicating with the interior thereof, an up and down. motion.

The upward motion of the suction pipes l9 brings them into contact with the bottom stamp in the magazine It. When there is suction in the hose 16, which is the case whenever the suction pipes I9 are in contact with the stamp stack, they will withdraw one end of the bottom stamp from the stack and pull it down to the periphery of the transfer wheel 29, which is provided with two cam-actuated clamps 2i and 21a, pivotally mounted thereon. The end of the stamp so deposited on the wheel 23 by the suction pipes i9 is gripped by one of the clamps 2! and Zia, whereby the stamp is completely withdrawn from the stack as the wheel 25 turns through half of a revolution, during which the stamp receives a coating of paste by contact with a paste wheel 22. At the end of the half revolution, when the trailing end of the stamp rests on the top of a package a cam roller mounted on an arm secured to the clamp encounters a raised portion 25 on a stationary cam 26, thereby swinging the clamp 22! open and releasing the stamp. At the same time, a diametrically opposite cam roller 21', connected in a similar manner to clamp Zia, engages a depressed portion 28 of the stationary cam 29, thus closing the clamp Zia upon the stamp just delivered by the suction pipes H The cam rollers 23 and El are held in engagement with cams 28 and 29 by a tension spring connecting the arm 24 of clamp 2! and the corresponding arm of clamp 2hr; the cams 2B and 29 are adjustably mounted on an arm 36 attached to the bracket l2, the hub 3! of arm 38 and the hub of the bracket [2 serving as bearings for the transfer wheel shaft 32. The latter is intermittently rotated step by step as hereinafter described.

The paste wheel 22 mounted on a shaft 33 is suitably supported and driven from the main drive of the machine. The paste wheel 34 has spaced flanges 35, the space between the flanges registering with the periphery of the transfer wheel 25 which fits into said space, thus preventing contact between the two wheels and keep ing paste from touching the periphery of the transfer wheel when no stamp is carried by it. The peripheries of the flanges 35 of the paste wheel have inwardly beveled surfaces 36, which arch the stamp as it is drawn between the flanges of the paste wheel by the transfer wheel and apply paste to the edges of the stamp S, see Fig. 3. With this arrangement of the paste wheel and transfer wheel all difficulties caused by drawing the stamps, which may be of vary ing thickness, through a constant clearance between the paste wheel and transfer wheel, as in the prior constructions, are avoided.

A pusher 31 which propels the packages P along the runway 38, the pusher being operated by suitable means such as shown in the prior patent to Nejedly, No. 1,682,406, granted Aug. 28, 1928, delivers a package to a point below the stamp transfer wheel. Just before the stamp S is released by the clamp on the transfer wheel, and While it rests on the top of the package, a cam-operated slide 39 descends, thus bringing a set of pressure fingers Ml in contact with the stamp on the top of the package and sealing the stamp thereon (see Fig. 8). The slide is reciprocably mounted in the bracket [2, and in descending carries along a bracket 4?, fixed to the slide and supporting a stud 42 on which is fulcrumed a bell crank lever in one arm 53 of which loosely mounted a stud M to which are secured the fingers 43, a tension spring being connected to the other arm of the bell crank lever and anchored to the bracket 4 l thus urging the arm 43 against a stop screw threaded into a lug of the bracket 4!. When the fingers ii! are brought into contact with the stamp on the top of the package during the descent of the slide they slide over the top of the package until the angular piece 45 on one of the fingers Ml engages the nose 45 or" the pusher 31. In this manner the fingers 40 are caused to slide over the stamp to smooth it and seal it to the top of the package. A set of folders 4! now descend and press one overhanging end of the stamp down and seal it against the forward side of the package, 9. The folders 4! are mounted on the stud 44 so that the descent of the slide 33 carries them into position to fold down and seal the overhanging end of the stamp to the side of the package.

The pusher 37 in moving forward, raises the fingers 48 and folders 4'! in order that the package may enter beneath the stationary top tension plates 48, the angular piece 15 which is then in contact with the nose 46 of the pusher being raised during the advancing movement of the latter, thereby swinging the fingers 43 and folders 47 upwardly on the stud 44 to permit the package to move under the plates 48. In this position a trip 49 carried by a collar 50 engages a pin 5i attached to an arm 52 due to the movement of arm 43 caused by engagement of the pusher with the angular piece as, and depresses the arm, the arm 52 being connected to the stud a l lifts the same, freeing the angular piece 45 from the pusher, thus returning it to its former position.

The pusher 3'! advances the package until it has passed a set of cam actuated folding fingers 53, Fig. 10. The pusher then retreats and a cam (not shown) actuates a rod 5 5 connected to an arm 55, which is attached to a stud 56 loosely mounted in the bracket S2. The motion thus imparted to the stud actuates the fingers 53 which are secured to the stud and thereby caused to descend and seal. the other overhanging end of the stamp against the package, 11, so that the stamp is now attached to three surfaces of the package P.

Referring now particularly to Figs. 1, 5, and 6 of the drawings, the no-package no-stamp mechanism will be described. The packages P issuing from the cigarette packaging machine travel over a runway 69. Arriving at the end of runway 6% the leading package encounters a feeler plate 8! attached to a projecting member 52 of a connecting arm 53. One end of arm is mounted on a stud 64 carried by the upper hubs of arm 65, the other end of arm being connected to a stud 66 carried by the upper hubs of arm 3?. The lower hub 58 of arm is mounted on a stud 55?, the ends of stud 59 being supported in bearings iii of a bracket if. The lower hub 12 of arm El is mounted and supported in a like manner.

A look plate 13 carried by a depending member 14 of the connecting arm engages with lock pin 15 attached. to a cam lever l5, which is pivotally mounted on a shaft ll actuated by a cam 4'3 through a cam roller E9. The cam is mounted on a shaft which is suitably driven from the drive of the machine. The upper end of cam lever 16 carries a stud 8| attached to which is a head 82 carrying a connecting rod 83 fastened to a slotted head 84 at its other end.

The bracket [2 carries a bracket 85 supporting a shaft 36 on which is pivotally mounted a bell-crank lever 81. The arm 87a of lever 8 carries a stud 88 engaging with a clutch lock pin 89.

A gear 90 loosely mounted on the stamp transfer wheel shaft 32, meshes with a gear (not shown) suitably driven from the drive of the machine. A clutch driver member 9! fastened to the hub of gear 90, drives through a lock pin 89, a clutch member 92 fixed on shaft 32.

Referring to Fig. 5, the extending arm 93 of lock pin 89, which projects through a slot in the clutch member 92, in the position shown, is locked against the stop stud 88. While in this position a spring 94 bearing against the pin 89 and seated in a bore in member 92 is compressed, so that upon release of the lock pin its semi-cylindrical portion 95, which fits a slot in the clutch driver 9! will be turned to engage in one of the semiannular slots 95 and Sta provided in the clutch driver ill. The gear 913 and driver 9! are thus free to rotate idly around the shaft 32 as long as the pin 8% is locked against the stop stud 38,

The operation of the device is as follows: The package P on runway 6H advances against the feeler i, thus moving the arms 65 and El, and the lock plate 73. When the lock plate has disengaged the lock pin '15, the cam 78 through roller #9 actuates the cam lever l5, and through the connecting rod 83 'actuates the bell crank lever 8?. A tension spring 97 having one end connected to the lever 8"! and the other end anchored to bracket 85 holds a stud 98 carried by the depending end of lever 81, against the forward wall of the slot in head 84. In this manner the lever 87 is caused to swing and stop against a pin 98 in bracket 85, the pin 99 being so positioned that it allows the stop stud 88 to swing away from the arm 93 of lock pin 89. The arm 93 thus freed permits the spring 94 to move it against the upper face Hill of the slot provided in the clutch member 92, thus moving the arm to its dotted position 93 (Fig. 5). In this dotted position a portion of the semi-cylindrical member 95 engages either of the semi-annular slots 96 and Sta thus making a direct drive to the shaft 32 and thereby turning the stamp wheel 2B. In the meanwhile the package P in tripping the feeler 6!, enters into a pocket of a transfer arm H)! which is suitably actuated by mechanism of conventional construction (not shown). The arm is! then swings from its horizontal position to a vertical position, bringing the package directly in front of the runway 38. Having arrived at this position, the pusher 3'5 sweeps the package from the arm onto the runway 38, and continues to push the same under the stamp wheel.

The shaft 32 having rotated 21 half-revo1u-' tion, brings the extending arm 93 of the lock pin 89 into engagement with a stop pin I112. The pin H32 is carried by an arm I 03 and connected by means of a stud Hi l to the upper end 87b of lever 8'1. The arm m3 is pivotally mounted on a stud ms supported in a bearing H35 carried by the bracket 85. At the completion of half revolu-' tion of shaft 32 the stop pin :92 disengages the direct drive of the clutch thus permitting the gear 90 and clutch member 9! to once again rotate idle around the shaft 32. In the interim the arms 65 and ii are returned to their original position by a tension spring It? (Fig. 6), thus locking the device. In case of a lapse in the delivery of the packages along runway 60, the feeler 6! retains its original position thus holding the locking device intact, and permitting the cam 18 to rotate idly. In this manner, the clutch 9H, 92 is held disengaged until the pusher 3? forwards the next package against the feeler iii. Thereupon the arm an) of the lever 8? is actuated to disengage the stud Hi2 from arm 93 of the lock pin 89, thereby permitting the spring 94 to turn the semi-cylindrical portion 95 of the lock pin into one of the slots 96 or 96a of the clutch member s, to rotate the transfer wheel. shaft another half turn, whereupon the stud 88 engages the arm 83, returning the lock pin to its inoperative position and thereby stopping the rotation of the transfer wheel shaft. The same cycle of operations is then repeated as long as packages are advanced by the pusher.

The bearing lfiii (Fig. 5) supports a bar IE8, which carries a brake band H39 partly surrounding the clutch member 92. The other end of brake band 5233 being fastened to a block Hi] attached to a spring tensioned rod MI. The rod' Ill is guided in a hole provided in bar Hi8. An adjusting nut i IE on the rod H 1 permits a slight drag to be maintained on member 92, thereby preventing the stamp wheel 29 from over-running its destination wh n the clutch is disengaged.
