11 Claims.

This invention relates to continuous rod' cigarette machines, more particularly to cigarette collectors or catchers for the same. The main object of the invention is to retard and stop the cigarettes issuing endwise from a cigarette machine cutoff, without injuring their ends. Heretofore the cigarettes have been gripped between stationary and/or moving surfaces which coacted to retard or halt them. In practice, however, it has been found that the cigarettes .were harmed by rubbing against the gripping surfaces, with the result that brush ends or the like were formed thereon.

With this purpose in view, the cigarettesare advanced from the cigarette machine cutoff onto a traveling surface on which they are displaced sidewise and retarded by a member moving transversely of the cigarettes. This member is provided with a surface engaging the rear side of the cigarettes and thereby displacing them. Said member may also be provided with an abutment arranged to stop the cigarettes and have a face overlying the top of the cigarettes and spaced sufiiciently' therefrom so that it will not grip the same and yet will be adapted to engage and retard the cigarettes as they rebound from said abutment;

A further object of the invention is to displace pairs of cigarettes simultaneously into spaced rows, without the use of diverging belts as heretofore.

Still another object of the invention is to provide an adjustment of the displacing member or trough which permits the same to be adjusted close enough tothe cigarettes. to retard them as they rebound from the stop, or closer, to grip the cigarettes, and thereby retard them;

In the accompanying drawings, which form a part of this specification and in which like characters of reference indicate the same or like parts:

Fig. 1 is a perspective View of the front of a of Fig: 1; showing an improved construction for" guiding the cigarettes from the cigarette machine cutoff to the segment roll.

In the particular embodiment of the invention illustrated herein, the cigarettes issuing endwise from cutoiT l of a cigarette machine. of con- 5 ventional construction are delivered onto plates 7 2 and 3 having ledges 4 against which the cigarettes are held by a leaf spring 5 (Fig. 7) until. they reach and are engaged by a segment roll. 6 (Figs. 1 and 2). cigarettes against an endless belt I, and as both the belt and the segment roll are traveling at' a speed in excess of the cigarette rod speed, a 1ongitudinal' acceleration and separation of successive cigarettes is obtained. The leaf spring 5 prevents acceleration of the cigarette until it is engaged by thesegment roll 6. If this were not done the cigarettes would get out of timed relationship, as the traction of the belt I on the cigarettes would vary at different speeds. The belt I is driven by a pulley 8 carried by a shaft 9 provided with a sprocket l0 driven by chain l I from a sprocket I2 on a shaft l3 driven from the cigarette machine or otherwise. The segment roll 6 is fastened on a shaft I4 which may be suitably driven from the cigarette machine at the same speed as the belt to clamp successive cigarettes thereon and thereby establish spaces between the same. The belt I advances the spaced cigarettes across the path of the displacing member l5. The latter may be constructed in the form of an inverted trough, if desired, comprising. a flat plate l6 and an angular plate I! (Figs. 3-6) fastened'by bolts I8 (Fig. 1) to connecting rods. l9pivotally mounted on rocker-arms 20 and actuated by cranks 2| fixed on a shaft 22 driven from. the cigarette machine. The crank shaft 22 may be suitably driven from the counter shaft 9 through a reduction gear or otherwise, so that their dead centers will coincide with the entry of the cigarettes into the trough and their release from thesame.

The pivots 23 of the rocker arms 20 are preferably mounted in vertically adjustable brackets 24' which are equipped with adjusting screws 25 abutting the pedestal 26 whereon the brackets are mounted. Upon adjustment of the latter, the connecting rods I9 will be raised or lowered with the trough l5, and the lock nuts I26 may be turned to maintain the brackets 24 in the desired position. In this manner the motion of the trough may be regulated to avoid gripping the cigarettes forwarded into the trough. Moreover, the adjustable mounting of the troughmay be readily regulated to accommodate'various di'-- The latter acts to clamp the ameters of cigarettes which come within the range of sizes of the cigarette making machine. After the requisite adjustment has been made the brackets 24 may be locked in position by the bolts 21. Slots may be provided in the plates I6 and I! as indicated at 8 in Fig. 1, to permit adjustment thereof vertically upon the bolts l8 to avoid interference with the belt I at the various adjustments obtained with the adjusting screws 25. To prevent adjustment of the trough into gripping engagement with the cigarettes, the brackets 24 may be im movably fastened to the pedestal 26 by dowel pins I21 after being adjusted to the proper position.

At its remote end the trough is preferably provided with a stop or abutment 29 (Fig. 1) which serves to halt a cigarette in a predetermined position after it has been displaced sidewise out of the path of the following cigarette. As the cigarettes are pushed sidewise by the rear side of the trough, it is believed that a current of air is created under the front edge of the trough which tends to lift the cigarettes into contact with the inner face of the top of the trough and thereby retard their endwise movement. To promote this mode of operation, the trough may be suitably perforated, for example as seen at 9 at the top in Fig. 1, to vent the air currents created during the transverse displacement of the trough, so that the cigarettes will be carried up against the inner face of the top of the trough, and thereby retarded. This trough may be lined with a strip 28 of sponge rubber, cork, or other suitable friction material which will assist in retarding the cigarettes. When it is preferred to displace a pair of cigarettes simultaneously, as is the case with high speed cigarette machines, the trough may have a gap wherein is arranged a stop 30 movable periodically into position to halt the second cigarette of each pair of cigarettes (see Fig. 5). For this purpose on a bracket 3| fastened to the plate I! may be pivoted a stop finger 33 which is pivotally connected to a rod 32 mounted in a block 33 swiveled in a pedestal 34 fastened to the housing 35 for the bearings of the crank shaft 22 (Fig. 2). On the end of the rod 32 projecting through the block 33 is arranged a compression spring 36 bearing against a collar 31 threaded on the rod, the spring normally urging ;the rod backward and preventing sliding movement of the rod in the block. At the end of the return movement of the trough the finger 30 assumes a position behind the trough, the necessary adjustment of the collar 3'! and the threaded connection 38 of the rod being made to permit the finger 30 to be swung into this initial position about its pivot on the rod 32. During its forward movement the trough comes down into a position overlying a pair of cigarettes advanced by the belt 1 in the spaced relation created by the segment roll 5, the trough assuming a more or less vertical position at this point and the finger 30 being swung into the median transverse gap in the trough (Fig. 1), to intercept the second cigarette of the pair therein (Fig. 5). The cigarettes are not retarded while still aligned with the cigarette rod, but are moved sidewise toward the back in Fig. 1, about one-half inch before contacting the abutment 29 and the finger 30. Following the rebounding of the cigarettes therefrom the air current produces a momentary contact of the cigarettes with the strip 28 and thereby retards and halts them while the trough continues its forward movement and displaces the pair of cigarettes across the support or table 39,

and onto the collecting belt 40, the trough moving upwardly and thereby swinging the finger 30 clear of the cigarettes (Fig. 6). Following this the trough is moved back to initial position together with the stop 30 (Fig. 3).

It will be understood that the trough may be adjusted through the agency of the adjusting screws 25 to grip the cigarettes while displacing them transversely, as indicated in Fig. 4. In that event the lining strip 28 will be formed of resilient material such as sponge rubber or the like, so that it may be compressed sufficiently to prevent injury to the cigarettes. In either case the cigarettes will be delivered in two spaced rows.

The collecting belt 40 is continuously driven by a pulley 4| fastened on a shaft 42 driven from the cigarette machine or otherwise. The rear plate 16 of the trough disengages the cigarettes shortly before they reach the end of a ridge 43 (Fig. 4) which is formed on the table 39 and is slightly higher than the upper run of the collecting belt. Due to the fact that the crank 2| is at a dead center at this stage, the trough is momentarily stationary. Therefore the cigarette will roll off the edge of the ridge 43 very slowly, and there will be no likelihood of slippage thereof on the collecting belt. Heretofore, when the cigarettes reached the collecting belt While being displaced sidewise at a substantial speed, slippage of the cigarettes on the collecting belt would occur and cause the cigarette to remain in position to be engaged by the following cigarette with the consequent danger of misplacement. Moreover, the cigarettes enter the trough while the crank 2| is passing through the other dead center, so that there is less likelihood of misplacement or injury thereof as with a member moving rapidly at this point.

In the event that a cigarette should enter the trough out of the desired timed relationship and obstruct the movement of the stop finger 30, the spring 36 is weak enough to permit the stop to yield. The obstructing cigarette, instead of being ripped open, will be displaced sidewise by the trough to a position wherein it may be conveniently removed.

The individual cigarettes delivered on the collecting belt 40 may be held back by yielding fingers 50, as shown in Fig. 5, until the following cigarette is advanced against it, whereby their combined resistance will be sufficient to raise the fingers and permit passage of the first cigarette. Heretofore, particularly at high speeds, the cigarettes were advanced so rapidly on the collecting belt 40, that there were no cigarettes left to stop following cigarettes, wherefore the latter were sometimes misplaced or turned askew. The motion of the fingers 50 may be limited by cross-pins 5| to prevent raising or flinging of the same into an ineffective position.

The top of table 39 may be grooved, as indicated by the dotted line I39 in Fig. 5, to permit the stop 30 to move into a position wherein its bottom edge is flush with or slightly below the bottom of the cigarette halted by it.
