This invention relates to cigar machines, more particularly to improvements in bunch rolling mechanism of the type disclosed in the patent to H. H. Wheeler, 2,311,011, issued February. 16, 1943. In this type of bunch rolling mechanism the bunch rolling pin is provided with a rider plate which is pivotally mounted on the rolling pin and is maintained ina forward position while therolling pin advances a loop in the rolling apron across the rolling table. While the loop in the apron is being advanced by the rolling pin, the rider plate holds the bunch charge .down upon the rolling apron to causethe charge to be coiled'upon itself. The riderplate is subsequently swung to a rearward position,'the rolled charge is then rolled within a binder positioned on the apron, and the rolling pin is returned with the rider plate to its initial position. However accumulations of paste and tobacco on the rolling apron may interfere with the return movement of the rider plate to its initial position and cause it to assume an upwardly inclined position instead of its normal horizontal position. Therefore when the rider plate reaches its initial position it may interfere with the passage of the bunch charge thereover onto the rolling apron.

One'of the main objects of this invention is to prevent interference with the return movement of the rider plate to its initial position by accumulations of paste or tobacco on the rolling apron. To this end the rider plate may be eccentrically mounted on the rolling pin so that the clearance between the rolling pin and rider plate will be increased sufficiently to permit passage .of the rolling apron therebetween without inter- I ference by accumulations of paste or tobacco on the rolling apron when the rider plate is returning to its initial position.

' A further object of the invention is to adjust the rider plate relatively to the rolling pin to vary the clearance between the rider plate and rolling pin. Heretofore the clearance between the rolling pin and plate was not adjustable. Occasionally, during the coiling of the charge upon itself while the rolling pin moved the loop in the apron forwardly and the charge was held against the apron by the rider plate, tobacco would escape through the gap between the rider plate and rolling pin. Moreover, when rolling aprons of different thickness were used the moveing aprons to freely pass through said gap. More-g,

ment of a thicker apron through the gap between .50

over the size of this gap may be regulated to vary the clearance sufficiently to prevent the escape of tobacco while the charge is held down by the plate and being coiled upon itself.

With these and other objects not'speciflcally mentioned in view the invention consists in certain constructions and combinations which will be hereinafterdescribed and fully set forth in the appended claims.

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 longitudinal sectional view of the mounting of the rider plate and the rolling pin.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1 showing the rider plate in its rearward position. a

Fig. 3 is a similar View showing the rider plate in its forward position.

Fig. 4 is an end illustration ona much smaller scale than Figures 1-3 of a cigar bunch rolling mechanism equipped with my improved rider p a e.

Referring to Fig. 1 of the drawings, it will be seen that the rolling, pin I0 is revolublymounted on bearings 12 carried by a shaft l4. provided with eccentric trunnion l5 and eccentric trunnion or pintle IS. The trunnion l5'is supported in the upper end of a bracket l8 fastened atits lower end as shown in Fig. 4, to the bottom of slide 20 which will later be described more fully. Trunnlon I5 is concentric with the trunnion or pintle l6, and trunnion or pintle I8 is also concentric with shaft 24 having a head 22 in which trunnion I6 is supported. Shaft 24' is carried in the upper end of a bracket 26 which is fastened at its lower end to the slide 20.

One corner of a rider plate 30 is fastened to a flattened portion 32 on a collar 34 rotatably The other corner of plate 30 is similarly secured to the head portion of shaft 24.

A slotted block IH (Fig. 4) supports the base I12 of the bunch rolling table (not shown) whose construction is fully described in Wheeler Patent 2,311,011 to which reference may be had for description of the rolling table. Block HI also supports the slide 20 which is provided with guide rollers I15 engaging slots-in base I72. Bracket I8 carries a ball stud I8l which is connected ;by a link (not shownlto a cam lever (not shown) the bunchrolling table.

rearward position shown in Fig. 2.

On the base I12 are fastened brackets I99 which carry the shaft 200 of a drum 20I which is provided with a longitudinal notch in which one end of the rolling apron 202 is secured. The rolling apron extends across a platform (not shown), which supports the bunch charge while it is being coiled upon itself and thence along the length ofthe bunch rolling table to which its outer end is clamped. The shaft 200 carries a sprocket 204, which is intermittently driven by a sprocket chain 205, to tighten and slacken the rolling apron. One of the brackets I99 has a bearing 20'! in which is journaled a shaft 206 carrying on one of its ends an arm 208 which is connected by links (not shown) to a platform (not shown) arranged in front of the rolling table. The platform may have a perforated top and a suction chamber so that the overlying portion of the apron adheres to the platform when it is lowered whereby a loop is formed in the apron. On the otherend of the shaft 206 .is secured an arm 222 which is connected by a rod 233 to-a cam lever (not shown). Suction may be maintainedin the platform .(not shown) by suitable ducts communicating with a pipe 2I'I connected to the suction system of the cigar machine. Since the construction of the platform and the mechanism for reciprocating slide 20 is fully described in WheelerPatent 2,311,011, further description thereof is deemed unnecessary. When the brackets I8 and 26 move the rolling pin rearwardly to its initial position in front of the suction platform, a flattened portion I86 I formed on the outer end of shaft 24 engages a slot in a shaft I81 supported in a stationary pedestal. Shaft I81 is then turned by mechanism described in Wheeler Patent 2,311,011 to swing the rider plate 30 through 180 degrees to its forward position shown in Fig. 3. On the portion of shaft 24 projecting from bracket 26 is clamped an arm or finger I93, which engages a stationary roller I94 (Fig. 4) while the rolling pin ismoving forwardly across the rolling table, and the rider plate is thus swung back to its .194 is mounted in an arm I95. Since the construction of the stationary roller I94 and arm I95 is fully described in Wheeler Patent 2,311,011 further description thereof is deemed unnecessary.

The bunch charge is advanced by a charge transfer, whose construction is shown in said Wheeler patent, across the rider plate 30 while same is in its rearward position and the rolling pin is in its initial position to deposit the bunch charge on the portion of the rolling apron overlying the platform. The rider plate is .then swung to its forward position after the platform has descended with the portion of the rolling apron adhering thereto and formed the loop in the apron required for coiling the charge. While the rider plate is being swung forwardly the drum MI is turned forward by chain 205 to pass out a length of the rolling apron 202 sufficient for the formation of the loop shown in Fig. 3. The forward movement of the rolling apron to permit formation of the loop is indicated by the arrow in Fig.2.

While in its forward position the rider plate acts to hold the charge down upon the rolling apron while it is being rolled upon itself during the forward movement of the rolling pin. The drum 20I then turns backward to tighten the apron about the coiled charge, and the arm I93 engages the stationary roller I94 to swing the The roller .4 rider plate into its rearward position. As the rolling pin moves to its extreme forward position, the charge is rolled within a binder deposited on the portion of the rolling apron overlying the bunch rolling table to form the cigar bunch. The cigar bunch is tightened by a final backward turn of drum and delivered from the loop of the apron ready to be transferred to the bunch shaping and wrapping mechanism.

Since the rider plate is in its rearward position while the rolling pin is being returned to its initial position, the clearance between the rolling pin and rider plate is sufficiently great to permit passage of the same over the rolling apron without interference by accumulations of paste or tobacco on'the rolling apron. Therefore the rider plate will be returned to its initial position without being displaced from its horizontal position shown in Fig. 3.

While the clearance between the rolling pin and rider plate is much smaller when the rider plate is at its forwardposition this clearance may be enough to permit tobacco to escape therethrough from the bunch charge being coiled upon itself in the loop of the apron. This clearance may be reduced to prevent the escape of tobacco by unloosenin the set screw II 5 holding the trunnion I5 in bracket I8 and turning trunnion I5 until the clearance is diminished sufficiently to prevent escape of tobacco therethrough. If the clearance is too small to permit free passage therethrough of the rolling apron, the trunnion is turned in the opposite direction. After either of these adjustments the set screw I I5 is tightened to hold the rider platein the adjusted position.
