Like references refer to like parts throughout the various figures of the drawings.

Referring to Figure 1, the cigarettes are contained in a hopper l, which is divided into three compartments 2, 3, and 4, and each of the compartments is formed with vanes 5 between which the cigarettes fall on to the bed of the machine. Each of the compartments 2, 3, and 4 has cooperating therewith, a conveyor provided with pusher pieces 6, each of which is arranged to remove a predetermined number of cigarettes from the bottom of the hopper and deliver them to the pockets 1 of an intermittent mould chain conveyor. As the batches of cigarettes delivered from the compartments 2, 3, and 4 have to be placed one upon the other in the pockets 1, each batch is delivered in turn to a table from which they are moved into the pockets 1 by plungers H2, H3, and H4. The plungers are operated simultaneously so that at each operation a batch of cigarettes is .delivered from each compartment into one of the three pockets positioned before the compartments as seen in Figure l. The cigarettes from the compartments 3 and 4 are delivered on to tables which are movable in a vertical direction and which, when a batch of cigarettes has been deposited thereon are raised to a level such that the plungers I I3 and l M can' push the batches into the pockets 1 without in any way interfering with the cigarettes already contained in the pockets. The vertical movement of the tables may be effected by any suitable cam or other mechanism, not shown. In this way it will be seen that at each movement of the pocket 1 before the hopper l, a batch of cigarettes is deposited into the pocket, and when the pocket 1 has received a batch of cigarettes from the illustrated in Figure 5.

of the bottom of the pockets 7.

compartment 4, it contains the required number of cigarettes for insertion into a container.

In some instances it is desired to include in the batch of cigarettes a pulling member 8 which is preferably constructed of thin carboard and is formed as illustrated in Figure 9. When it is desired to include one of these members, they are contained within a stacker 5 from which they may be removed by a suction device similar to that shown in Figure 8 and described hereinafter, and .are fed between belts I5 and are deposited on the plate ll between guides l2 (see Figure 3) which are positioned above the pockets of the mould chain conveyor. When the members 8 are in the position described, a plunger 23 (see Figure l) operated by a cam l4 and a lever l5, moves them into a position at which they are operated upon by a pair of pivoted folders !6 (shown in Figure 3) operated by cam surfaces I! formed in the plunger head l8 of a presser l8, which is operated by a cam 20 and levers 2| and 22. The presser l9 is arranged to hold the member 8 firmly on the plate I l whilst the folders l5 fold the portions 23 and'24 of the member 8 beneath the cut-away portions 25 of the plate ll. During the time that, the portions 23 and 24 are being folded by the folders Hi the plunger I5 is held in a stationary position, and. after the portions 253 and 26 have been folded, the presser E9 is raised and the plunger I3 is again moved and passes the members 8 between the guides 26 and during their movement between the guides 26 and the portions 23 and 24 spring outwardly, due to their natural resiliency, and assume a position shown in Figure 9. The plunger I3 delivers the members 8 beneath a further plunger 2'l which is also operated by the cam 20 in such a manner that as the presser l9 operates togrip a member 8 as above described, the plunger 21 descends and presses the folded member downwardly into the pocket I which is positioned before the compartment 2. Just before the plunger 2? presses the member 8 into the pocket a group of cigarettes has been delivered into the pocket from the compartment 2, so that the member 8 is pressed by the plunger 27 on to the upper surface of this group of cigarettes. 'The remaining groups of cigarettes from the compartments 3 and 4 are then deposited on to the top of the member 8.

The filler pockets containing batches of cigarettes are then moved to a position at which they are removed from the pockets 1 and are inserted between a pair of folder blocks 28 and 29 which are arranged to fold a strip 30 of wrapping material around the batch and'also to align the wrapped batch of cigarettes with the open end of a tin.

Referring to Figures 2, 5, 6, and 7, the strips of wrapping material 38 are fed from a reel 3| from which the wrapper lengths are severed by means of cutting mechanism 32, and the severed strips are deposited on to a table 33 from which they are moved by a horizontally moving plunger 24 and deposited on a plate 35 in the manner When the strips 30 are delivered on to the pla e 35 between the open folding members 28 and 22, the folding members and plate 35 which are slidably mounted on a carrier 35 are at a level which is below the level The folding mechanism is then raised to the level of the bottom of the pockets l, the carrier 35 being moved upwardly by any suitable mechanism, not shown. During the upward movement of the carrier 36,

the folding elements 28 and 29 are arranged to move inwardly towards each other, and assume a position shown in Figure 6. In order to effect the sliding movement of the folders 2B and 29, they are connected by means of pivoted arms 3'! and 38 to fixed brackets 39 and 45. It will be seen from Figure '7 that any vertical movement of the carrier 36 will cause the folders 28 and 28 to move towards or away from each other. The plate 35 is fixed to the folder 28 so that it moves with the folder, and so enables the wrapper 30 to be supported during the whole of the time that it is in position between the folders 28 and 29.

When the folders 28 and 29 together with the wrapper 30 have been raised to the level of the pocket I as shown in Figure 6, a plunger 41 is arranged to push the cigarettes endwise out of the pocket 7, and deposit them between the folders 28 and 29, and on the wrapper 35. After this operation is completed, the plunger 4! is moved away from the folders 28 and 29 and the carrier 36 is then again caused to move upwardly to the level of the tins into which the cigarettes are to be inserted. During this further upward movement of the folders 28 and 29 the folders are caused to move still further inwardly until they assume the position shown in Figure 7, from which figure it will be seen that they are completely closed together thereby forming the batch of cigarettes into a shape substantially that of the container into which they are inserted, and the diameter of the formed batch is slightly less than the diameter of the tin into which they are tobe inserted, in order to facilitate their insertion intothe tin.

The folders 28 and 29 are provided with spring catches 42 and 43, which are arranged to fold the wrapper 30 in such a manner that one edge overlaps the other.

In order to facilitate the operation of the folders 28 and 29 in forming the batch into the desired'cross-section the cigarettes, during their upward movement with the folders, are agitated in order that they may more readily conform to the gradually altering configuration of the folders 28 and 29 as they are brought together. The agitation is provided by a pair of racks 44 and 45, with which pawls 45 and 41 connected with the arms 31 and 38 'co-operate during the upward movement of the folders. The racks 44 and 45 have faces which press against rollers 440 and 44! mounted on the folders 28 and 29. These latter are pivoted at 285 and 290 and are spring urged by springs 28I and 29L As the arms 31 and 38 carry the pawls upwardly, the pawls engage the racks 44. and 45, and agitate the latter, and these in turn agitate the folders 28 and 29.

When the folders 28 and 29 reach their uppermost position they are in alignment with the open end of a tin which is lying on its side, as seen clearly in Figure 8, the tins having been brought into position by the pockets 48 of the intermittent conveyor 49, the tins being fed into the pockets down a chute 50 as clearly seen in Figure 2. A stop 5! operated by a cam 52 and levers 53 and 54 is arranged to prevent a tin from proceeding down the chute until a pocket is in position to receive the tin.

In some cases it is desired to place one or more discs containing advertising matter, or coupons, or pictures in the tin, and when this is the case, they are preferably inserted into the tin before the batch of cigarettes is inserted thereinto. Referring to Figure 2, two disc feeding apparatuses 55 and 56 are shown, one of the apparatuses being for agitating shown in detail in Figure 8.- The discs are contained in am'agazine 51-, from which they are fed by an oscillating suction device 58,0f known construction, and are fed between a pair of rollers 59 which feed the discs between bands 6!] operative to feed the discs down a before the open'end of the tin '62. When a disc is in'position, a plunger 63 is arranged topress the disc into the tin, and if the disc is provided with a centre aperture as are the discs shown in the disc feeding device 55 illustrated in Figure 1, the plunger 63 may be made in two parts, as shown in Figure 8, the part 64 being provided to align the disc in the tin and the portion 64 is prevented from moving right to the'bottom. of the tin by means of the stoplifi, secured thereto, which is arranged to engage with'the stop 66 before the portion 63 presses the disc against the bottom. of the tin. V s '7 After "the discs-have been inserted into the t n,

' the tin is brought into position before the formed batch of cigarettes, and a plunger 61 is arranged to engage with the cigarettes and press. them into the open end of the tin? Whilst the cigarettes are being inserted into the tin, a gripping member 53 is arranged to descend'and grip the tin between the bottom of the pocket is and the gripper as, so; as to hold the tin against endwise movement dur-1.: ing the insertion of the cigarettes. ensure that the wrapper which has been wrapped about the cigarettes is moved into the container together with the cigarettes, andis not displaced during the movement, the plunger 61 is provided with small projections 69, which cooperate with slots Ill formed in the folding elements 28 and 29 as seen clearly in Figures 4 and'T.

The filled ti'ns are then moved into position before a table or travelling band "I I, at which position an ejector Hoperated by a cam 13 and lever 14 is arranged to engage with theunderside of the tin and to eject it from the pocket 38 of the conveyor 49, and toplace the tin in an upright pos1 tion upon the band or table I l The e ector I2 is turned about its ivot until'it engages the underside of the tins, after which it moves through an arc until the tins are in an upright position. The filled tins may be removed from the band or table ll manually or by any suitable means, or f desired the band 1| may convey the filled 131115 10 mechanism for sealing the open ends of the tins.
