CIGAR-BUNCH MACHINE.

Application filed February 7, 1925. SeriaI No. 7,483.

()ur invention relates to an improvement in cigar bunchmachines and more particularly to an improvedreaper.

In cigar bunchmachines of the automatic. type, provided with an intermittent filler feeding device, such, for example, as forms thesubject-matter of the U. S. Letters Patent granted to Meyer Bayuk No. 1,538,082 dated May 19, 1925, there is required some means, as a reaper, for removing the fillers from the feed, positioning them for trimming by the corrugated knives and placing them in the filler transfer.

The handling of the fillers, as by the reaper, presentsa'problem of some complication, since the fillersinust be taken from the feed, positioned for trimmin and after they are trimmed passed to the fil er transfer and at the same time always keeping the tiller under control so as to prevent the tobacco forming the filler from separating. To retain the fillers in the form in which they are entered in the feed by the operator, it is found necessary to maintain a certain amount of pressure on the fillers during their movements bythe reaper and while they are bein trimmed.

Now it is the objectofour invention to provide reaping mechanism to withdraw the fillers from the feed, position them for trimming andenter them in a transferring device without loss of form.

Further objects of our invention are to provide a reaper which will be highly efiicient and durable in operation and at the same time simple in construction and free from the necessity for complicated or frequent adjustment.

Having now indicated, in a general way, the nature and purpose of our invention, we will proceed to a detailed description thereof with reference to the accompanying drawings, in which we have illustrated a preferred embodiment, and in which-- Fig. 1 is a sectional viewof a portion of a cigar bunch machine showing a part of a reaper and its operating mechanism in accordance with our inventlon.

Fig. 2 is a sectional view similar to Fig. 1 showing a reaper embodying our invention, in association with a filler feeding device.

Fig. 3 is a plan viewof the subject of Fig. 2.

a filler feeding device comprising a pair of endless chains 11 passing over suitable sprocketsd and to which are secured transversely extending bars 0, each serving to support a plurality of spaced clips or fingers f beneath which a filler h is adapted to be placed by an operator. The chains 0 are driven intermittently in a step-by-step manner from a sprocket 7} on-' a driven shaft j, through a chain is engaged with a sprocket Z loosely mounted on a shaft m which carries sprockets n engaged with chains 0. The sprocket l is intermittently connectedwith shaft on through the engagement of a spring-pressed pawl o carried by sprocket Z in one of four notches g in a disc 7* keyed to shaft m. Ad-

jacent the disc 7' and loosely mounted on shaft m. is a cam disc 8 having a cam surface cutin its periphery and adjustably secured to a support t by mean'sof bolts passing through arcuate slot at in the support. A pin 1) extends laterally from the pawl 0 and rides on the periphery of cam disc 8 and controls the entry of pawl 0 into notches g in disc 1'. The/pawl is allowed to enter a notch g when the pin rides into the cut-out portion in the periphery of the cam disc and is lifted out of the notch when the pin rides out of'th'e cut-out portion. WVhile the pawl is in a notch g, the shaft m will be turnedand the chains 0 and fingers f advanced. The time of entry of the pawl into a notch and the distance the feed is ad-. vanced is determined by adjustment of the cam disc 8, aswillbe obvious from inspection of Fig. 7.

' At the end of the feeding device thereis struction for trimming and cutting out the ends of the tiller prior to the application of the binder.

Above the strips w are a plurality of ski bars 3 secured adjacent their rear ends to a cross member 2 pivotally mounted on trunnions 2. A bar 3 extends transversely of the ski bars and is adapted to be lifted, against the action of a weight 5 suspended from it, by means of lovers -11 actuated by cams 6 connected with the forwardipair of feed chain sprockets (Z to raise the ski bars and permit them to fall under the influence of weight 5 for the purpose to be hereinafter explained.

Adapted to be operated between the strips '10 are a series of spaced reaper fingers 8 turned up at the rear ends as at 9 and provided with heel portions 10 at the forward ends. The fingers 8 are mounted on a cross member 11, which is supported by the turned-up ends of a pair of parallel supporting bars 12. Adjacent the ends of the bars which support the lingers, the bars are longitudinally slotted, as at 7, for the reception of the ends of a. pin 13 passing through a knuckle 14 on one end of a lever 15, the other end of which is pivoted to the frame of the machine. The opposite ends of the bars 12 are pivotally secured to a block 16 slidably mounted in slots formed in brackets 17 supported from shaft m and the frame of the machine. The lever is adapted to be oscillated by means of a cam disc 18 mounted on a shaft 19 and on the side of which is formed a cam surface 20 adapted to be followed by a cam follower 21 carried by the lever. The rods 12 are adapted to be reciproeated through the medium of connecting rods 22 pivotally connected to the block 16 and to the cam wheel 18 and to corresponding, crank disc 18 also mounted on shaft 19. Thus, it will be observed that if the wheels 18 and 18 be rotated the rods 12 will be reciprocated and oscillated and the cam surface 20 being properly designed the reaper fingers 8 supported on the ends of rods 12 will be moved from the position shown in full lines, F ig. 1, longitudinally of the strips 10 to the position shown in dotted lines, Fig. 1, then donwwardly, longitudinally and upwardly again to the position shown in full lines, Fig. l.

Secured to disc 18' is a sprocket wheel 23 over which passes a chain 24 engaging a sprocket wheel 25 mounted on a shaft 26, an adjustable idler sprocket 27 being provided for adjusting chain 24.

The shaft 26 is adapted to be intermittently driven by means of a small gear 28 mounted on the shaft and a large gear 29 mounted on a shaft j which is continuously driven, as shown in Fig. 1. The gear 29 is provided throughout part of its periphery with teeth and is partly blank, as indicated, the ends of the section being beveled off as indicated at 30. The periphery of the small gear 28 is also provided with a blank section. The gear 29 is continuously rotated and while its teeth are in mesh with the teeth of gear 98, the gear 528 is driven. However, in the rotation of the gears, the blank section of gear 28 meets the blank section of gear 2!) and the blank section of gear 28 will ride thereon. hen the end of the blank section of gear 29 is reached due to the bevel, indicated at 30, the teeth of the two gears will mesh and gear 28 will be again driven.

If now it be assumed that the clutch coir trolling the actuation of the filler feeding device and the relationship of the gears 28 and 29 be arranged so as to properly time the actuation of the filler feed and reaper, the operation of the device will be simply explained.

Referring to Fig. 2, assuming the feed to be at rest, the reaper actuating mechanism has just come into operation and the reaper fingers are raised with their upturned rear ends 9, behind a, filler 71 in the clamps f, and the heel portions 10 behind a filler 71.: The reaper moves longitudinally draws the filler h from the feed and pushes the filler 7! into the jaws of a. transfer device 31. When the filler 71 is entered in the transfer, the filler It will have been positioned over the dies 0:, with which a cutter cooperates. The reaper then rests and the cutter operates and the jaws of the transfer device close. The reaper fingers then are moved rearwardly, downwardly and upwardly, during which the feed device moves, to come to rest as the reaper fingers move upwardly to a position to withdraw a filler.

The ski bars are normally yieldingly held by weight- 5 so as to bear on the fillers 7: and h under the control of the reaper, their forward ends being lifted by cams 6 to permit the feeding device to advance a filler to the position shown in Fig. 2.
