CIGARETTE- PACKE T-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 665,241, dated January 1, 1901; Application filed January 3. 1900. Serial No. 230- Lllo model' To all whom, it may concern.-

Be it known that. I, FRANK J. LUDINGTON, a citizen of the United States, residing at No. 63 Bank street, Waterbury, county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Cigarette-Packet- Filling Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present machine is designed to intermittingly receive previously-prepared packets in chambers upon an intermittingly-rotating carrier-wheel and to present them successively to a feeding chute through which the cigarettes are transferred to the packet. The packet is then discharged from the chamber in the wheel.

The apparatus is adapted to operate with packets of oblong rectangular form with open mouth at one end for application to a taper-- ing nozzle upon the chute. Such packets are made by automatic machinery, and the present machine may be attached to such packetmaking machine to receive the packetsdi rectly therefrom as they are produced, and in such case the driving-shaft of the present apparatus would be connected by suitable gearing with the driving-shaft of the packetmaking machine to operate in unison therewith. To simplify the illustration, the present apparatus is shown disconnected from the packet-making machine and its driving shaft provided with a pulley to actuate it independently. The cigarettes are delivered to a hopper, which feeds them into a chute, from which they are forced into the packets, which are presented successively to the nozzle of the chute. The packet is adapted to receive two layers of cigarettes, and the chute is formed with two adjacent vertical channels communicating with channels upon the opposite inclined sides of a hopper, and a segmental agitator is vibrated in the hopper to roll the cigarettes crosswise into such channels. A reciprocating punch is divided vertically and moved transversely through the channels at thehottom of the chute to force two layers of the cigarettes from such channels into the packet, the packet being first forced upon the nozzle of the chute by a movable plunger in the bottom of the packetchamber. Fingers are arranged upon the sides of the chute, which intermittingly support the two layers of cigarettes above the path of the punch, but permit the cigarettes to move downward in the channels after the punch is retracted. The plungers in the packet-chambers are operated by a cam to force the packets forward upon the nozzle of the chute when required and to afterward discharge the filled packet from the chamber when the latter is turned downwardly. The invention includes the various constructions for carrying out these operations and will be understood by reference to the annexed drawings, in which- Figure 1 is a front elevation of the ma chine with a diagram of a mandrel a, from which each packet Z) is delivered to chambers .0 upon. the carrier-wheel d by rolls 1 or other suitable means. Fig. 2 is an enlarged cross-section of part of the carrier-wheel and the block for operating the plunger, the view being taken on line C D in, Fig. 1 looking toward the cheeks r of the chamber 0. Fig. 3 is a rearelevation of the machine. Fig. 4 is a diagram showing the forcing of the packet b upon the nozzle 9 of the chute. Fig. 5 isa diagram of the means for turning the chambered wheel d. Fig. 6 shows the right-hand end of the machine with the rear side of the hopper and chute removed, part of the slide ll and its connection 12 being broken away to expose the chute. Fig. 7 shows the devices for actuating the fingers a. Fig. 8 shows the left-hand end of the machine in section, where. hatched, upon the line A Bin Fig. 3, excepting the cam O and wheel 22, which are shown in section upon their center line. Fig. 9 is a plan of the machine. Fig. 10 is a partial plan in section, where hatched, on the center of the wheel and chute. Fig. 11 is a front view of the nozzle upon the chute. Fig. 12 is a side view of the same parts with a part of the punch 10, cigarettes 50, and packet 17. Fig. 13 is a plan showing the bottom of the chute 2 and nozzle 9 in section, with the cigarettes in the chute and the end of the punch 10 adjacent to the ends of the cigarettes. Fig. 14 is a perspective view of the packet; and Fig. 15 isa diagram showing the forcing of the packet backwardlyinto the chamber 0 (upon the carrierwheel) by the advance of the punch 10.

The machine is shown with stand g supporting a bed-plate h, carrying the spindle '0 of the carrier-wheel d, which is formed with eight packet-chambers c. A shaft j, journaled on the stand, carries a cam for the punch, a pulley Z for operating the agitator, a crank m for intermittingly rotating the wheel, a cam n to actuate the lockingpawl 19, and cam 0 for pushing the plungers s (in the bottoms of the chambers) outwardly when required. The cam-shaft j is rotated by gears 20 and adriving-shaft 21 and is also provided with a hand-wheel 22 for adjusting the position of the parts. The carrier-wheel d is formed of a thin disk rotated on a horizontal axis with notches '1: in the edge to engage a locking-pawl p and has upon one side eight radial grooves q to engage a pin or roll upon the end of the crank m. (See Fig. 5.) The opposite fiat side of the disk is provided with a corresponding number of the packetchambers 0, each formed with adjustable checks 0' and plunger .9, which plunger is moved by means of a block if, fitted to a radial slot 10 in the plate. A shaft 1; extends through the spindle 'v of the carrier-wheel, as shown in Fig. 3, and is oscillated by connections 8 8 to cam 0 and operates to intermittingly turn an ejector-cam having a groove (lettered w in Figs. 3 and 4) to fit rolls t upon all of the blocks 15. (See Figs. 3, 4, and S.)

The body of the cam, inside the groove, is formed with a tooth to and an adjacent notch 10 the tooth operating upon the roll, as shown in Fig. 4, to push the block and the plunger forward when itis required to force the mouth of the packet upon the nozzle 9. The notch 10 is then turned opposite the roll upon the block 15, so that when the punch forces the cigarettes into the packet the latter may be stripped from the nozzle 9 by the advance of the punch. The cam having groove 10 oscillates to move the tooth past each of the rolls upon the block twhen the packet-chamber stands before the nozzle 9; but the rolls traverse the entire groove in the cam as they move to and from such position, and the expansion of the groove in the cam serves, in the required position of the disk, to push the plunger forwardly and eject the filled packet from its chamber. The cam-groove 0 and camgroove to thus operate coujointly to actuate the plunger 8 in each of the packet-chambers. The cam 0 is clearly shown in Fig. 1 actuating the crank 8 upon the shaft 1) by means of a link 8, carrying a roll fitted to the camgroove 0, such groove being formed to oscillate the crank 8 once in each rotation of the shaft j through the angle between the full and dotted positions of the crank, which are shown in Fig. 4.

To arrange the cigarettes a; for the packet in two layers, as shown in Fig. l, the chute 2 is divided by a vertical partition 6 to receive two layers of cigarettes from the hopper. The chute has vertical apertures e upon opposite edges at the bottom, through which the divided punch passes in discharging the cigarettes. The hopper 3 has sloping sides and a triangular block 4 in the bottom, having sides parallel to those of the hopper, forming two opposite discharge-channels 0, leading into those in the chute. A segmental agitator 5 is pivoted within the hopper to oscillate over such block,whichis formed with a corresponding concave surface. (See Fig. 6.) The upper sides of the agitator slope outwardly and serve, with the inwardly-sloping sides of the hopper, to lead the cigarettes into the marginal channels, and the periphery of the agitator is proportioned to roll the cigarettes successively against the sides of the hopper and to thus introduce them crosswise transversely into the channels. The agitator is constantly vibrated by an eccentric 6 and connections 7, the eccentric being rotated by gears and a cord from the pulley Z. (See Figs. 1, 6, and 8.) A tapering nozzle 9 is projected from the discharge-apertu res e at one edge of the partition e nearest the carrier-wheel. The nozzle is thus in line with the lowest live cigarettes in each of the channels (see Figs. 1 and 11) and is situated to receive the open mouth of the packet when presented by its chamber a in line with the apertures. The nozzle is formed of four elastic flaps, two of them being longer than the others, in correspondence with the wide and narrow sides of the packet. The longer flaps are extended vertically at the outer sides of the apertures 6 and the two shorter flaps are extended, respectively, across the top and bottom ends of the apertures. The outer ends of the flaps form an open passage as wide as one of the apertures, and the outer end of the nozzle is thus sufficiently smaller than the two apertures to be readily introduced within the mouth of the packet when the latter is forced toward the nozzle. The opening of the nozzle is thus made of such a size that the cigarettes may be'forced through the nozzle into the packet Without bending the flaps very materially or producing any serious resistance to the movement of the cigarettes, which would tend to injure the same. A punch 10 is divided vertically, so that one-half may pass on each side of the partition 6, and it is reciprocated through the bottom of the chute and the nozzle by means of a slide 11 and connections 12 to the cam 7c. Fingers z are hinged upon the sides of the chute above the discharge-apertures and penetrate the channels 6 above the group of ten cigarettes which is to be discharged by the punch, (see Figs. 0 and 7,) and are actuated by toes y, through the medium of a crank 13, oscillated by a rock-shaft l4 and by a sloping dog 15, attached to the slide 11. An arm 16 upon the rock-shaft is pushed upwardly by the dog 15 when the slide is retracted, as shown in Fig. 1, which serves to separate the fingers and permit five cigarettes to drop in each channel before the punch is advanced. Each of the blocks t, which actuates the plunger 3, has a rod 17 projected toward the edge of the carrierwheel d, (see Figs. 3 and 8,) and a dog 18 is provided on the slide 11 to contact with this rod when the punch has forced the cigarettes to the bottom of the packet.

The machine operates as follows: The shaft rotates continuously and intermittingly turns the carrier-wheel one-eighth of a revolution in the direction of the arrows 23 by means of the pin or roll in upon the crank m, which pin enters one of the grooves q and shifts it to the position of the preceding groove. The locking-pawl p normally engages one of the notches t' in the rim of the carrier-wheel, but is lifted by the cam n acting upon an arm attached to the pawl during the shifting of the wheel, as is shown in Fig. 5. While the wheel stands still a packet 19 is forced into the packet-chamber 0 upon the top of the wheel and is ultimately brought opposite the nozzle 9 to receive the cigarettes. (See Figs. .1 and 4.) The cam w is held stationary in the position shown in full lines in Fig. 4 by a concentric curve upon its actuating-cam 0 (see Fig. 1) until each packetchamber 0 is opposite the nozzle 9, the rolls upon the blockstsuccessively traversing the cam-groove w. The cam 0 then turns the projection to past the block if, as shown in Fig. 3, the projection (in its movement) forcing the plunger 3 outwardly to press the packet upon the nozzle, as indicated by dotted lines b in Fig. at. The packet b is shown thus applied to the nozzle in Fig. 12. The cam is then forces the punch 10 through the chute, as shown in Figs. 3 and 11, thus propelling the cigarettes at until they reach the bottom of the packet, as shown in Fig. 10. The notch 10 then stands opposite the roll 25 upon the block and permits the plunger .9 to be pushed backwardly; but if such movement were elfected by pressure upon the cigarettes they would be injured, and the dog 18 upon the slide 11 is so adjusted as to contact with the rod 17 as the cigarettes reach the bottom of the packet, and such rod shifts the block 15 and presses the plunger backwardly into the chamber, so that the continued movement of the punch may force the packet off of the nozzle without any sensible pressure upon the cigarettes. In this movement of the block i the roll 25 passes into the notch w, as shown in Fig. 3, and the succeeding rotation of the carrier-wheel moves the roll from such notch past a projection 10 into the cam-groove to. (See Figs. 3 and 4.)

The projection 10 operates to force the roll outwardly, as shown in Fig. 3, and discharges the filled packet from the chamber, as shown in Fig. 1.

It will be readily understood that the cigarettes require a guide to lead them into the mouth of the packet and that the flaps forming a nozzle upon the chute are enabled by their elasticity to retain a tapering form (shown in Figs. 1, 11, and 13) while receiving the mouth of the packet and to then permit the cigarettes to separate the flaps, as shown in Figs. 10 and 12, when they are forced through the nozzle into the packet. Without such a nozzle the cigarettes could not be readily directed into the packet, and unless the nozzle were tapered and formed of elastic flaps the mouth of the packet could not be readily applied to the nozzle and the cigarettes then forced through the same into the packet.

As the partition 6 divides the chute into two channels all the way to the bottom, it is necessary to split the punch 10, as shown in Fig. 9, so that its two parts may pass through the aperture 6 at opposite sides of the partition, as shown in Fig. 10, in discharging the cigarettes to the packet. The cigarettes are thus delivered in two layers or groups into the packet, as desired, while the two layers are effectively separated in their passage from the hopper to the discharge-apertures 6 (See Figs. 6 and 7.)

The adjustable cheeks 1', which form in conjunction with the plungers s the chambers to receive the packets, are secured adjustably upon the disk of the carrier-wheel, as shown in Fig. 1, and the plungers are also secured adjustably and removably upon the blocks 15. By this construction the machine may be adapted to operate with packets of various sizes, as the plungers may be supplied of any desired width and the cheeks adjusted adjacent to their edges.

The elasticity of the nozzle upon the hopper adapts it to cooperate with packets of various sizes; but thehopper itself may be changed, if desired, and replaced by one of other dimensions, as the foot of the hopper is merely bolted to the bed-plate h, as is clearly shown in Figs. 6, 7, and 10.
