11. Claims.

This invention relates to an improvement in cigarette machine catchers or collectors of the type intended to receive the cigarettes as they issue, in a single file, from the cigarette machine cutoffv and to deliver them in side-by-side row formation.

The main object of the invention is to suctionally retard and, if desired, stop the longitudinal movement of the cigarettes as they issue from the cigarette machine cutoff while pushing them sidevvise on to the collecting belt.

To this end in the present invention, each cigarette, after having been cut from the cigarette rod, is pushed under a rotating roller formed of or covered With rubber or similar material and provided With a raised segment which engages the cigarette and speeds it up, thus separating it from the following cigarettes. Just as the raised segment of the roller is about to release the cigarette, a pusher contacts with the side of the cigarette and pushes it out olthe line of the cigarette rod and delivers it to a belt conveyor constituting the collecting belt.V

The pusher may be provided with suction ports terminating in its iront face, and When the said tace contacts With the side of the cigarette it acts to retard the same and tlius reduce the momentum imparted to the cigarette by the speed-up roller and, if desired, stop its longitudinal motion. As the pusher continues lts advance, it delivers the cigarette on to the con* tinuously moving collecting belt. The collecting belt is provided with a plurality of spaced rows of suction holes which successively register with the branches of a conduit connected tothe source of suction, at the time a cigarette is* being deposited thereon by the pusher. Thereupon the suction applied to the suction ports of said pusher is shut off and the cigarette is suctionally retained4 on the collecting belt While the pusher retreats into position to advance the next cigarette, and the cigarette is carried away on the collecting belt. In so' doing, the next row of suction holes in the belt is brought into register with the branches of the suction conduit to rec'eivev the next cigarette from the pusher. A further object of the invention, therefore, is to suctionally retain the cigarette on the collecting belt while the pusher is retreating, in order to prevent clinging of the cigarette to the retreating pusher.

A modified form of cigarette catcher is provided in which the cigarette, after having been cut from the cigarette rod, is pushed under a rotating roller, similarly formed of or covered with soft friction material and provided with a (Cl. 198-24l raised segment, Which accelerates the cigarette and separates it from the cigarette rod. When the raised segment of the latter roller is about to terminate its engagement With the cigarette,

a pusher traveling in an orbital path contacts with the side of the cigarette and pushes it out oi line of the cigarette rod and advances it across a set oi rows of suction holes provided in the top of a stationary suction chamber.

As the front face of the pusher contacts with the side of the cigarette it acts to frictionally retard the same slightly and thus slightly reduce the momentum imparted to the cigarette by the speed-up roller, and, as the pusher arm continues its orbital-motion and delivers the cigarette over the first row of holes provided in the stationary suction chamber, the suction in the latter gradually stops the longitudinal motion of the moving cigarette. The pusher then retreats and advances the next cigarette across the suction chamber in the same manner. In advancing, the second cigarette pushes the previously delivered cigarette ahead to a second roW of suction holes which arrests the same. The next advance of the pusher deposits another cigarette on the first row of holes, and, in so doing, the leading cigarette is pushed on to a collecting belt. In being stopped on the second row of suction holes, the cigarettes are kept from being misaligned before reaching the collecting belt.

Accordingly, still another object of the invention is to suctionally retard and stop the cigarettes before they reach the collecting belt, Without misaligning them. With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described and then specifically set forth in the claims hereunto ap- .pended In the accompanying drawings which form a part of this specilication and in which like characters of reference indicate the same orV like parts:

In carrying the invention into effect there is provided means for accelerating cigarettes delivered from a cigarette machine cutoff in endto-end relation and thereby separating them lengthwise, a traveling collecting belt arranged transversely of the line of cigarettes delivered.

from the cigarette machine cuto, mechanism for pushing the separated cigarettes sidewise on to the belt, and suction means operating to stop the longitudinal movement of the cigarettes While they are advanced sidewise. In the best constructions contemplated the suction means may include a suction chamber having a perforated top on to which the cigarettes are propelled by the accelerating means. The cigarette pushing mechanism may include a slidable pusher provided with suction ports terminating in its operating face, springs normally holding said pusher in retracted position, a rotating crank arranged to periodically engage and advance the pusher to push a separated cigarette sidewise, and stationary vacuum chambers registering with the port holes of the suction ports, whereby the longitudinal movement of the cigarette will be suctionally retarded while it is advanced sidewise by the pusher; or the cigarette advancing mechanism may include a pusher and means for moving said pusher to push the separated cigarettes across the top of the suction chamber, whereby the longitudinal movement of the separated cigarettes will be retarded and stopped.

These various means and parts may be widely varied in construction within the scope of the claims for the particular devices selected to illustrate the invention are but two of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the specific constructions shown and described.

As the invention is applicable to any cigarette machine of the continuous rod type, a description of the latter is deemed unnecessary. The following description will be coniined to an illustration of how the cigarettes, after they have been cut off from the cigarette rod, are picked up and passed through the cigarette catcher in such a manner as to be lined up in side-by-side formation on the collecting belt.

Referring now to Figs. 1, 2, and 3, the cigarette C, after having been cut off from the cigarette rod and pushed along by it over a stationary table or plate I, passes under a speed-up roller I0. The latter may be formed of sponge rubber or other suitable material mounted on one end of shaft II, on the other end of which is a helical gear I2 meshing with and driven by a helical gear I3 on a shaft I4 suitably driven from the main shaft of the cigarette machine. At a predetermined point the cigarette will be engaged by the raised segment Illa of the roller II) and its speed increased, thus separating it from the rod, as the peripheral speed of the raised segment Illa of roller I0 is greater than the linear speed of the cigarette rod. The rotation of the roller I0 is so timed that its segment Illa will initially engage the cigarette behind its leading end and disengage the cigarette in advance of its trailing end to prevent crushing the cigarette ends.

At the instant the segment Ia of roller I0 releases the cigarette the pusher I5 engages the cigarette and pushes it sidewise out of the line of the rod and on to a collecting belt I6.

A reciprocating motion may be imparted to the pusher I5 by means of a crank Ill fastened to a vertical shaft I8 'journaled in a bearing I9 of a bracket ZI). II'he shaft I8 carries a helical gear 2l which meshes with a helical gear 22 mounted on shaft I4. A stud 23 on the arm I7 supports a roller 24, said roller during a portion of each rotation of arm I'I engaging with and advancing the pusher I5.

The pusher I5 is equipped with a rib 25 which is guided in a slot provided in a bracket E@ having spaced communicating vacuum or suction chambers hereinafter described. Springs 21, spanned between

spring posts

28 and 29, normally hold the rib 25 of the pusher I5 against a stop lug 30 of the bracket 2l). In this position the pusher is ready to engage and advance the cigarette, and the spring 21a spanned across posts 28a, and 29a. holds the pusher down in engagement with the slot in the bracket 26.

A suitable source of suction, such as an exhaust fan or vacuum pump (not shown), is connected with the vacuum chambers of the bracket 2S through a pipe 3l which branches from a main pipe 32. The pipe 3I is in open communication with the suction chamber 33 of the bracket and with the chamber 33a which is provided at its top with an elongated vent or slot 34 which normally registers with the port holes 35 of two suction ports 38 in the pusher I5. At its top the chamber 33 is provided with an enlarged vent 35 which registers with a port hole 3l of a third suction port 38 in the pusher I5. These ports 38 extend from the front or operating face of the pusher to their port holes 35 and 31, and in this manner the suction is maintained at the front face of the pusher, thus gradually retarding and, if desired, stopping the longitudinal movement of the cigarette after it has left the speed-up roller IB. By this means each cigarette may be stopped at practically the same predetermined position. The suction ports 38 are equipped with needle Valves 39 which permit regulating the degree of ,A

suction in the individual ports. In case of overtravel the cigarette will stop against an abutment 40 adjustably mounted on the pusher.

The cigarette C (Fig. 3), after having been severed from the cigarette rod, is advanced by the rod until it passes under and is contacted by the raised segment IIla of the speed-up roller I which thereupon separates the same from the rod. As the cigarette advances to position C' it moves along the front face of the pusher, the

suction applied to said face gradually retarding or, if desired, halting the longitudinal movement of the cigarette. At this time the roller 2f on crank I'I engages and advances the pusher to a dotted position thereby advanced to a dotted position C" on the collecting belt I6. While the pusher is advancing to this position the suction is cut off as the port holes 35 and 3l of the ports 38 move out of register with the suction chambers 33 and 33a.

the pusher is eliminated. The suction through I5; and the cigarette C is 1f,

the perforations in the belt also serves to retard and' stop any continued longitudinal movement of the cigarettes after the pusher has advanced them into the range of action of the suction through the belt.

The cigarette is suctionally retained on the belt I6 atv the position C", by means of branches 42 of the pipe 32 which are placed in such a manner that the perforations 4l of the belt I6 pass over and register with the open ends of the branches 42. The belt lli runs over an idler pulley 43 mounted on shaft 44 and over a pulley (not shown) which is driven from the mainv shaft of the cigarette machine. The pulley 43 is provided with a; number of spaced annular grooves 45 which receive the ends of the branches 42 and are large enough to clear the same.

Figures i4 to 9, inclusive, illustrate schematically a modified form of cigarette collector. In this arrangement the cigarettes, as previously mentioned, enter under the speed-up roller l) mounted onone endv of a shaft 5l', the other end carrying a helical gear 52 meshing with a helical gear 53 mounted on shaft 54. At a predetermined point the cigarette is contacted by the raised segment 5de of the roller 50 and its speed is increased, thu's'- separating it from the rod, as the peripheral speed of the segment 50a is greater than the linear speed of the cigarette rod.

At the instant the segment 50a of roller 50 releases the cigarette the pusher 55 has swung alongside the cigarette, and as it continues its orbital path it pushes the cigarette sidewise on to a stationary suction chamber 56 which may be connected to a suitable source of suction.

The orbital motion of the pusher 55 is produced by its mounting on crank pins of the

cranks

51 and 58 xed on the lower ends of vertical shafts 59 and 60, respectively, on the upper ends of which are mounted helical gears Si and 62 meshing with helical gears 63 and 64, respectively, on a counter-shaft 54 driven from the cigarette machine.

When the segment 50a is about to release the cigarette, the front face of the pusher 55 engages and pushes the cigarette sidewise over a row of4 holes 65 in the top of the suction chamber 56 which gradually stop the longitudinal movement of the cigarette C as shown in Fig. '7. The cigarette C is thus suctionally retained on the holes 65 while the pusher retreats into position to engage and advance the next cigarette, and in advancing the latter the previously delivered cigarette C' is pushed to a second row of suction holes 66 which hold the cigarette C while the cigarette C is held by suction holes 65 as shown in Fig. 9. During its next advance the pusher forwards the next cigarette against the cigarettes which are suctionally retained on the chamber 56, whereby the leading cigarette will be deposited on a traveling collecting belt 61 and the following cigarette will be stopped on the suction holes 66. In stopping on the second row of suction holes 66 the cigarette is kept from being misaligned before reaching the collecting belt.
