The belt 135 also passes around the roller 137 carried by a shaft 138 suitably journalled in the frame. 139 designates a shaft mounted above the belt 135 and provided with radial blades 140 which serve as tobacco spreaders. The shaft 139 is journalled in bearings 141. 142 and 143' designate sprocket wheels around which passes a sprocket chain 144. 145 designates a worm having a shaft 146 journalled in bearings 147 and 148 and this shaft 146 also carries the pulley 133.

Referring now more particularly to Figure 19, 149 designates a worm wheel which has fixed to it a ratchet 150. 151 designates a driving arm for the feed belt as best seen in Figure 18. The arm 151 has pivoted to it a pawl 152 against which bears a spring 153.

Referring now more particularly to Figure 17, 154 designates a ratchet which carries a knock-out cam 155 and is provided with a 156. 157 designates a knock-out lever whlch is pivoted at 158 and is actuated by means of a pin 159 carried by the rock arm 160 which is fixedly mounted to one end on the shaft 125. 161 designates a sprocket wheel around which passes a sprocket chain 162 which also passes around a sprocket wheel 163 mounted on a shaft 164. 165 designates bucket chain sprocket wheels and 166 designates lower sprocket wheels around which pass the bucket chain 167. The upper shaft is mounted in bearings 168 and 169, see Figure 9.

' The feed hopper is carried by the standards 174 and 175 and is braced by the tie rods Referring now to Figures 8, 9, 10 and 11, 177 designates tobacco arch breakers or levelling devices for the sides of the buckets and 178 designates a tobacco leveler for the rear of the bucket. The bucket chains pass over guide rolls 179 which are journalled at 180. The feed hopper is provided with a division space 181 and with a tobacco shield 182 which latter is positioned in proximity to the upper sprocket wheels in proximity to the path of the buckets so that the tobacco cgrried thereby will all fall into the chute 1 1.

The operation of my novel automatic cigar bunching machine Wlll now be readily apparent to those skilled in this art and is as follows The tobacco is placed in the supply hopper orjsource of supply 173, see more particularly F i ures 1, 2, 8 and 9. The main driving sha t 27 of the organized machine is driven by means of any suitable source of power. The main driving shaft 27 is driven by the worm 91, as illustrated, the shaft of said worm having the pulley 96 thereon which is driven by means of any desired source of ower. The worm shaft also has mounted t ereon a pulley 95 around which passes a belt 182 which also pases around the pulley 133 on the shaft 146 to thereby drive it. The worm 145 on the shaft 146 drives the shaft 138 carrying the sprocket wheel 161, see more particularly Figure 14, thereby driving the sprocket chain 162, see Figure 9, which passes around the sprocket wheel 163 on the shaft 164. In this manner the bucket chains 167 are driven thereby causing the buckets 17 0 to travel within the hopper or source of tobacco supply 173 and carry the tobacco in measured quantities therefrom. The surplus tobacco carried by the buckets is removed by the knock-off or levelling members 177 and 178, see Figures 8 and 10. As the buckets pass up and over the sprocket wheels the excess tobacco carried thereby drops by gravity into the hopper 173. On the continued movement of the buckets the tobacco therein is delivered into the chutes 171 which discharges the tobacco onto the travelling belt 135 in a thin layer which is spread out by the spreading blades 140 of the spreader 139 so that a uniform layer of tobacco is carried by the conveyor, apron or belt 135.

The shaft 139 of the spreader is driven by means of sprocket chain 144 which is driven from the shaft, 136, see Figure 14. It will discharged into the scale pan 122, the

counterweight being adjusted so that when 'a determined quantityhas been received in the scale pan 122 the lever 124 will rock on its journal 125 and the scale lever will come to rest against the lower ad ustable stop 129. As soon as the scale pan comes to rest, the rotation of the shaft 138 is auto- 7 matically arrested thereby stopping all the feeding mechanism which contributes to feed the tobacco from the hopper 173 to the scale pan 122. The arm 160 is fixedto the shaft 125 to rock with it when the lever 124 rocks so that when the scale pan 122 moves downwardly the lever 160 will rock downwardly thereby moving the pin 159 from the position seen in dotted lines in Figure 17 into that seen in full lines so that the pin 159 moves out of engagement with the shoulder on the pawl 157 thereby permitting the pawl 157 which is weighted at its lower end to rock on its fulcrum 158 and moves into engagement with the teeth of the ratchet 154 on the shaft 138 and thereby stop any movement of the ratchet 154 which is loosely mounted on the shaft The shaft 138-has fixed to it the arm 151 which carries the pawl 152 which co-operates with the ratchet 150 which is revolved by the worm wheel 149 and the worm 145, it being seen that the revolution of the ratchet 150 co-operating with the pawl 152 is the means for effecting the revolution of the shaft 138, see Figures 14, 18 and 19. As soon now as the ratchet 154 is stopped and since the shaft 138 continues to rotate the cam 155 will raise the pawl 152 out of engagement with the teeth of the ratchet 150 so that the rotation of the shaft 138 will be arrested, thereby stopping the feed of the tobacco towards the scale pan as before explained.

It will now be understood that the scale pan 122 has received a predetermined weight of tobacco and the next step is to discharge it from the scale pan.

Referring now more particularly to Figures 1 and 6, the shaft 27 is at this time revolving thereby revolving the cam 26 thereby actuating the rock arm 21 which in Figure 6 is in its normal or neutral position. The revolution of the cam 26 in the direction of the arrow seen in Figure 6 causes the link 20 to move upwardly thereby rocking the lever 16 on its fulcrum and causing the pawl 78 to engage the cam end of the lever 74 thereby moving said lever upwardly moving upwardly with it the link 111 and rocking the lever 114 on its fulcrum so that its forward end, see Figure 16, will press downwardly on the arm 130 and rock the scale pan 132 on its fulcrum 131. Since thescale an 122 is open at its back the tobacco will drop from the scale pan in frontof the usher 84, see Figure 3.

As the lever 4 has been rocked on its fulcrum in the manner described its upper end .73 will press against the pawl and move it away from the bar 61 so that the guides 65 and 66 will drop downwardly by gravity and form a pocket in the apron 12, as shown .in dotted lines in Figure 3, thereby forming a confined space to receive the tobacco which is now to be moved thereto by the pusher 84. The projections 90 on the cams 26 and 47, see Figures 6 and 7, now engage the pin 89 thereby rocking the lever 86 and causing the lever 85 to move forwardly, see Figure 1, thereby advancing the pusher 84, see Figure 3, to cause the predetermined weight, of tobacco to pass into the pocket of the apron 12. The shaft 27 in the usual manner rocks the lever 42 thereby rocking the links 35 and 33 therebyv the pawl 100 into engagement with the teeth of the ratchet 98 so that the shaft 27 will have imparted to it one revolution and then automatically stops in the usual manner of standard types of bunching machines. The tobacco is pushed into the pocket of the apron after being fed thereto by the pusher 84 by means of the plunger 62 which is positively raised and lowered in the manner which will now be described. The plunger 62 is fixed to the rod 58, see Figure 1 and Figure 2. As the cam 47 on the shaft 27 revolves, see more particularly Figure 7, the link 49 will be moved downwardly and thereby actuating the rock arm 50 to rock the lever 55 on its fulcrum and draw downwardly the link 57 and thereby the rod 58, it being understood that the continued revolution of the cam 47 returns the plunger 62 to its raised position, and retains it in such position until the phuiger is to be again moved downwardly.

The parts are S01 constructed that the weight of the lever 86 causes the pusher 84 to be returned to its initial position seen in Figure 3 ready for the next operation. As soon as the pawl 78, see Figures 1 and 6, rides under the shoulder on the lever 74, the lower end of the lever is dropped thereby causing the free end of the lever 114 to move upwardly and the scale pan 122 returns to its normal or neutral position seen in full lines in Figure 13. As soon as the tobacco is discharged from the scale pan the counterweight 136, see Figure 13, causes the lever 124 to return to its horizontal position there- 'by rocking the shaft 125 to raise the lever 160, see Figure 17, in an upward direction and thereby move the pawl 157 out of engagement with the ratchet 154 and retain it out of engagement with such ratchet.-

The spring 153 bearing downwardly on the pawl 152, see Figure 18, causes the cam surface 155 to partially revolve the ratchet 154 thereby permitting the pawl 152 to engage the teeth of the ratchet 150 and the feed of the bucket chain 157 and the conveyor aprons 135 and their adjuncts will take place in the manner already hereinbefore described.

In so far as I am aware, I am the first in the art to employ mechanically controlled means to automatically deliver to the paron from the source of supply a predetermined and definite weight of tobacco so that the cigars as manufactured will be of standard weight and size. This has heretofore been deemed impracticable.

My present invention while particularly adapted for a short filler is not limited to such use but can be employed for a long filler. The filler is raised from the bottom of the storage hopper so that the tobacco is retained at all times in a loose condition and the conveyor buckets will be uniformly filled in such a manner'that they will always carry a defini e quantit of tobacco as they carry a surplus which is levelled ofl' prior to the discharge of the tobacco from the bucket.

' The parts are so timed and the buckets are of such dimension that the amount carried by a bucket is preferabl I less than the amount of filler required or a single cigar so that therecan be no crowding or contacting of the tobacco which would have a tendency to clog or obstruct the machine.

In accordance with my present invention scrapped tobacco of any nature may be 'einplo ed and damped tobacco can be employed if esired.

It will be apparent thatI have devised a novel and useful automatic cigar bunching machine which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
