ing curl-1 or othe t on cigarettes, the machine being of the class which tips the individual cigarettes.

ti o present invention an improvement upon the machine shown and described in a a application for patent filed by Alexander when on the 31st day of January, 1908, serially numbered 413,555, to which cross reference is made; and the present case contains an ilustration and description of only so much of a complete machine as is e es ary to illustrate the application of my L t invention to a machine of the character contained in said application.

and

a. hopper for feeding the cigarettes .t..-ly to a carrier, which will at all ii cs feed the cigarettes singly and without g any damage to the cigarettes and in the cigarettes in the hopper will be cut off as a cigarette is being fed to the carrier.

Tii'here is also improvement in the means for preventing choking of the cigarettes as they enter between the revoluble drum and oscilating guard as they feed to the carrier.

My object is also to improve the means for applying the tips by providing a plurality of fingers for wrapping the ends of the tips upon the cigarettes, which fingers lie below the path of the cigarettes and are to a position above the bottom of the 3 as it is presented for tipping and which are then alternately moved further to wrap the tip ends on the cigarette.

I also prov'de flexible member, such 'eooject of my present invention is to an apron, which lies between the fin-- l have also provided means for laterally positioning the cigarettes on the carrier they come in position for tipping so that there will be perfect registering of the machine and all tendency of the machine to improperly tip the cigarettes or to distort the la ter during the tipping is avoided.

Gther features of improvement such as the -iring pressed wiping plate for wiping the irettes as they leave the applying means will appear hereinafter.

in the construction of a machine for the utilization of my present improvements many of the parts, such as the conveyer or carrier, the operating shaft, the cork feeding and cutting means and the frame may be the same as that shown in the application herein referred to and the parts herein shown which are inconsistent with, or additional to the parts there shown, may be applied to such machine.

As the general construction of the machine may be understood from said application I vey them to the tipping means, the chains being adapted to travel around the sprockets 2 and 3 on the shaft 1, and on the sprockets 4, 5, on the shaft 8, at the other end of the machine. The carrier is adapted to be moved intermittently by power derived from the main operating shaft through a set of gears as described in the application cited. The hopper or feeding means for discharging the cigarettes on the carrier is preferably disposed some distance from the tipping means and is adapted to discharge the cigarettes successively into the holders '7 and preferably with the ends to be tipped projecting beyond the carrier. The hopper and its parts are shown in Figs. 1 and 2 and are as follows; a reservoir or hopper is mounted on brackets 11, preferably above the carrier and under the hopper there is a revoluble drum 12, having an uninterrupted periphery which will not destroy the cigarettes; and the drum is intermittently revolved as shown in the said application. A guard 13, is mounted so as to lie a sufficient distance from the drum 12 to allow the cigarettes to pass, flatwise, through the space. 14, the guard being curved to correspond with the periphery of the drum. The guard is supported upon the arms 15 and 16, which are mounted upon the shaft 17, and a rod connected to an arm 19 on the arm 16, oscillates the guard 13 as in the said application. There is a discharge and cut off plate 20 which is mounted with trunnions 21 upon guides 22 at opposite ends of the cut off plate, the pins or trunnions 21 being adapted to move in the slots 23 in the guides 22, so that the cut off plate may be moved on its axis away from the drum in case a cigarette should become wedged between the drum and cut off, preventing any clogging, or destruction of the cigarettes. An arm 24 on the cut off is connected by a link 25 with an arm 26 on the oscillating guard, so that when the latter oscillates it will oscillate the cut off plate on its pins 21. The cut oif plate is so shaped that only one cigarette will pass at a time and without injury, while the others above it are properly cut off, it being understood that the cut off is located above the carrier, which latter is so arranged that the holders 7 will be positioned below the cut off at each stop of the carrier. The cut off may be better understood from the cross section shown in Fig.

1. The lower part 28 is curved, preferably concentric with the trunnions 21, so that the convex side faces toward the cigarette passageway, which convex portion is sufficient, together with the space between it and the drum to allow a cigarette to pass between the cut off and the drum, when the cut off plate is oscillated. Above this convex portion the plate curves inwardly at 29, sufficiently close to the drum to cut off the cigarettes when the same is in the position shown in Fig. 1; and it then curves outwardly and upwardly at 30 and preferably extends beyond the limits of the guard 13. There is connected to the arm 26 of the guard, a link 27, which extends upwardly and is fulcrumed through the wall of the reservoir to a reciprocating plate 31. The plate 31 lies against the inside wall of the reservoir with its curved lower edge 32, near the point where the cigarettes enter between the drum and guard 13; and the plate is reciprocated by the link 27 at each operation of the guard. Springs 33 press the trunnions 21 inwardly to keep the cut off plate in its normal position.

The operation of so much of my invention is as follows: The carrier presents a holder 7 for the reception of a cigarette when the guard 13 will be rocked on its shaft. This will work the cigarettes down between the drum and guard. As the guard thus oscillates, it will, through the link connection, oscillate the cut off. The cigarette lying immediately above the cut off will be allowed to drop when the part 29 moves away from the drum, until it falls on the concave portion 28, which has moved into the path of the cigarette. The return oscillation of the cut off will allow the cigarette to drop from the part 28 onto the carrier and the part 29 will out off the remaining cigarettes. WVhen this oscillation takes place the plate 31 moves up and down, which agitates the cigarettes and tends for a time to out off the cigarettes near the entrance to the passageway 14, as well as aiding in turning over oval cigarettes, to cause them to enter the passageway edgewise. Then the cigarettes are fed on the carrier they are moved successively into position for tipping, with their ends projecting beyond the carrier.

Gn the shaft 9 there are two cams 71 and '72, the former of which operates the arm 38 and the latter the lever 51. The arm 38 starts to rise on the part 49 of cam 71 and the lever 51 is at the same time rising on the cam 72 until the arm 51 is on the top of the part 74. While the lever 51 is riding on the surface 74, the arm 38 is continuing to rise on the part 49 of cam 71 until the parts are in the position shown in Fig. 6. Upon the continued movement of the cams the arm 38 moves down to the face 73, after which the lever 51 meets the rise of cam 72 and successively presented ind when s l 0 feet oi these increments on the tipping parts will appear hereafter.

lheJe is a plate op ite one of the stopping stations of the carrier holders over which the ends or" the several cia" stops long 7 ed the ca to be apph to the cigar tte. preferably JlElCQLl just unde T16 path of the cigarette so t. .t the latter will be prevented from being pressed dawn and distorted. The plate is rrovided ith a slight depression and r over the plate is a flexible member So which I have ter red an apron and which m y be made of canvas or other flexible mater ihe apron is held down on the plate by pin placed over the deprc ion in the plate so that the top of the pin and the a i on on the sides thereof are fiush. The ends of this apron are puller. taut by he spring 37, which ha *e their free ends secured to a stationary part or" the machine. Below this apron there is pair of tipping fingers which lie below the path of travel of the cigarettes but which move upwardly and apply the tip ends about the cigarette, the apron at such ti .cs remaining between the fingers and the tip so that the fingers do not contact directly with the tip. The tipping fingers and their action are clearly shown in Figs. 5, 6, and 9 to 11.

There are two curved arms or levers 38 and 39 which are tulcrumed at all and all respectively to suitable supporting means and they are provided on their upper ends with the presser fingers l2 and a3 which are tulcrumed to the levers and springs on the levers press the free ends of the fingers downwardly. There are stationary abutment pins l5, l6, with which the fingers engage, the pins serving to prevent the fingers dropping out of place; and when the fing rs move with their carrying arms the shouldes 4'7, e8, contacting with the pins force the fingers upwardly against the action of the springs. ll hen a cigarette is presented for tipping the parts are in the position shown in 5 and 9. The apron lies innnedi ately over the plate and the corl: or other tipping material is fed out over th apron w means shown in the application cited the cigarette end to be tipped is held o. the cork. by the carrier. The ends of the fingers l2 and 43 lie below the apron ant. to each side of the plate 34, where they are out of the path of the cigarette when the latter plate is a partial revolution of the cams the arms 38, 39 are each rocked, when the fingers .2, a3, will rise slightly until they carry the apron part way around the cigarette and of course with it the tipping material. The

further revolution of the cam 71 will cause the arm 38 by reason of the raised cam face l9,act ing on the arm 38, to rock the latter w the finger 42 will rise over the top of t cigarette and pressing the apron therew ii cause one end of the tip to adhere to the cigarette. During this movement the other finger remains idle, in the position last described; where it will brace the cigarette and prevent any distortion thereof by the action of the finger The finger %2 he 1 recedes to the position shown in dotted lines in Fig. 5; and the finger e3 then raised to carry the opposite and free end of the tip upon the cigarette where it will overlap the first end. lhis latter action is caused by the cam face 50 moving the end of lever 51. which latter is iulcrumed at 52 to a support, when the upper end operating through a link 53 connected with apart of the arm 55%),

ill rock the latter.

The lever 39 then recedes to its position previously assumed, when both arms or levers 38 and 39 will ridedown on their carnsand the fingers e2 and 43 will recede simultaneously to their lower positions shown in Fig. 5.

The cam actions are as follows: When the arm 38 rises on one side of the part if? of cam 1, the lever Si is rising on one side of the part 7% of cam 72, this causing both ti ping fingers to more up until they are on pposite sides of the cigarette. When the lever 51 reaches the part 74: it travels th on, when the finger a3 remains on one si being further raised until it reaches the top of 4:9 when the finger 42 will reach over the cigarette and apply one end of the tip as shown in 10. It (the lever 38), then rides down to the part 73 of its cam, withdrawing the as to the side of the cigarette. Lever 51 by that time goes up on the rise 50 and causes finger $3 to go on further and apply the other end of the tip when both arms 38 and lever 51 ride down on their cams together.

During the actions just described, the apron contacts directly with the tip. which apron being flexible. and held taut by the 7 1 its springs it gradually leaves the tip, by a moves to and trom the tipping means. Upon peeling actiomwhich will prevent any tendency on the part of the tip to follow the fingers.

The. cigarette in the previous explanations is numbered 5l and the tipping material 55. The feeding and cutting means for the tip material may be the same as in the applicati on referred to.

As a means for adjusting the cigarette laterally on the carrier holder when it comes up for tipping and for holding it against lateral displacement during the tipping I employ a simple device, the preferred form of which is shown in Figs. 3, 4, and 12. I have provided an arm 56 which is hinged upon a pin 57 to suitable supporting ears 58, the arm extending over the carrier and located so that its depending guiding fingers 59 will straddle a cigarette on the carrier when it is presented for tipping. The fingers 59 may be adjusted on the arm 56 by means of the screws 60, to bring them in proper position. There is a coil spring 61 on the pin 57, having one end secured to one of the ears 58 and the other pressing on the arm 56, so that the latter will be forced downwardly thereby, to the position shown in Fig. 3, full lines. There is an annular presser foot 62 which is positioned over the carrier and it is adapted to clamp the cigarette on the holder 7 when opposite the tipping means, to prevent any dislocation of the cigarette on the carrier during tipping, the same as in the cited application. This foot is carried upon an arm 63 which in turn raises and lowers on the rod 6&, being actuated by a cam 65. Each time a cigarette is presented on the carrier for tipping the presser foot is brought down on the same to hold it on the carrier during the tipping and is raised immediately thereafter by the cam 65. On the rod 64; there is a block 66, on which there is a lateral pin 67, the ends of which engage the arm 56, underneath, and preferably not far from the latters hinge. The presser foot 62, while the carrier is moving a cigarette up, is raised, and the arm 56 is sufficiently raised by the pin 67 to hold the positioning fingers 59 free of the cigarette. When the carrier stops the presser foot 62 moves down and at the same time the pin 67, when the spring 61 will rock the arm 56, until the fingers 59 straddle the cigarette, when the latter will be properly positioned, if it is not already so. The arrangement of the parts is such that the fingers 59 will position the cigarette before the presser foot engages the cigarette. Upon the completion of the tipping the foot will be raised by the cam action and also the arm 56, when the carrier will move to present another cigarette. As the carrier moves, the seam of the tip which has just been applied will be wiped by the plate 68, which is hinged at 69 and pressed down by a spring 70.

A modification of the lateral positioning fingers is shown in Fig. 13. In this case the fingers 59 are placed on the presser foot and move with it. I prefer, however, to use the first form as the positioning will be better and the presser foot need not rise so far.

accomplish much better results than heretofore. The cigarettes are properly fed to the carrier from the hopper and should they jam, or turn over in passing through the passageway 14, the cut off plate will be swung out on its trunnions against the action of the springs. When the cigarette is presented for tipping the fingers 59 will position the cigarette laterally, when the presser foot will grip it and hold it during tipping. The tip applying fingers 42, 43, will then move up until the apron partly surrounds the cigarette. The fingers then alternately rise and carry the tip ends over and press them onto the cigarette. As they alternately perform their functions they recede to their half raised positions and then recede below the path of the cigarette. Instead of the fingers contacting directly with the tip, the apron intervenes between the two and when the fingers recede the apron withdraws from the tip by a peeling action which will not remove the tip from the cigarette. The partial raising of the fingers and the retention there of one while the other applies its end of the tip to the cigarette prevents either finger from distorting the cigarette during the tipping.
