To all whom it may concern.-

Be it known that I, OLUF TYBERG, a citizen of the United States, residing at New York, county of New York, and State of New York,

have invented certain new and useful Improvementsin Cigai.-l\lachines,fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improvements in cigar-machines, and more particularly in cigar-machinesof the type disclosed in the patent to J. Reuse, No. 552,447, granted December 31,1895. In the machine described in this patent the cigar is rolled by means of manipulators in the form of two sets of pivoted jaws, each set being caused to swing bodily about the axis of the cigar as a center in order to roll the cigar and each set being swung about its pivot so as to be alternately opened and closed to grasp the cigar. After the cigar is rolled both sets of jaws are opened in order that the cigar may be removed from them by a lifting device attached to the machine. In the machine referred to the sets of manipulatoraws are operated through levers which have slotted ends, the said slotted ends being engaged by a rotating operating-rod. This rod working in the slotted ends of the levers operates not only to give the jaws their bodily swinging movement, but also turns them on their pivots to open and close them. lllanipulating-levers having slotted ends of the character described are difficult and expensive to construct, inasmuch as the slots in which the operating-rods operate must be formed with the greatest nicety in order to secure a successful operation of the levers. Furthermore, inasmuch as the rods operate in the slots both to open and close the manipulator-jaws, the said jaws are given a positive movement in closing and always close a definite amount. The effect of this positive closing movement is that if the bunch varies in size, as will often happen, satisfactory results are not attained. If the bunch be large, the jaws will close too far upon it and crush it, and if, on the other hand, the bunch be small, it will sometimes happen that it will not be grasped by the jaws with sufficient firmness to enable it to be successfully rolled. Furthermore, in the machine referred to, when both sets of manipulator-jaws are to be opened to deliver the cigar already rolled and to receive a fresh bunch, the machine is stopped in such a position that one set of jaws is open. The other set of jaws is then opened by forcing the jaws and the pivot-rod upon which they are carried downward away from the axial line around which the cigars are rolled. The operating-rod for the jaws, which is at this time stationary, acts, in connection with the lower forked ends of the manipulatorlevers, to force the jaws apart, exercising in this operation a cam action on the jaws. The mechanisin for accomplishing. this function is in the machine referred to complicated and ex pensive, and, furthermore, requires the use of the expensive slotted manipulator-levers before referred to.

It is one of the objects of this invention to so construct the levers through which the manipulator-jaws in machines of the class described are operated as to render it unnecessary to fork or slot them, as has been heretofore' done, thus considerably decreasing the cost of manufacturing these levers.

A further object of the invention is to do away with the positive closing mechanism which has been heretofore used and to sub 8o stitute therefor closing devices which permit a variable closing movement, thereby insuring effective action of the manipulator-jaws when the bunches vary in size.

A further object of the invention is to simplit'y and improve the mechanism for opening the manipulator-jaws and also to simplify the mechanism by which the manipulator-levers are operated and controlled.

\Vith these and other objects in view the 0 invention consists in certain constructions and in certain parts, improvements, and com bin-ations, as will be hereinafter described, and more particularly pointed out in the claims hereunto appended.

In the accompanying drawings, which form a part of this specification, and in which like characters of reference indicate the same parts, Figure 1 is a top plan view of a machine constructed in accordance with the invention. Fig. 2 is a rear elevation. Fig. 3 is a sectional view on the line 3 3 of Fig. 2

looking in the direction of the arrow 3. Fig. 4. is a sectional view on the line 4 4 of Fig. 2 looking in the direction of the arrow 4. Fig. 5 is a detail sectional view illustrating the action of the jaw pening device. Fig. 6 is a detail elevation, partly in section, of the manipulator-jaws and their levers.

Referring to the drawings, which illustrate a preferred form of the invention, 1 1 indicate the end frames, in which the operating parts of the machine are mounted. These frames are formed to provide bearings 2, in which are mounted short studs 3. One of these short studs serves to support a pair of swinging guides 4 t and the other stud a pair of similar guides 5 5, each pair of these guides being thus located at opposite ends of the machine. These guides are pivoted on the studs 3, and thus have an axial movement about the studs. Mounted in these guides t 4 and 5 5 and preferably whollysupported by them are longitudinal rods 6 and 7, the rod (3 being carried by one guide of each pair and the rod 7 by the other guide of each pair. \Vhile the rods 6 and 7 are preferably so mounted as not to turn in the guides, they may of course be journaled in bearings therein, so as to have an axial movement, if desired. In any event, however, they will be so mounted as not to have any play or sidewise movement with respect to the guides. These rods [3 and 7 serve to support the manipulator-jaws and their operating-levers, as will be hereinafter described.

Mounted on the rod 6 are a pair of manipulat0rjaws and 11, these jaws being provided with operating-levers 8 and 9. In the machine shown the levers are formed integral with the manipulator-jaws; but it is obvious that they may be separate therefrom and secured thereto if thought desirable. The manipulator-jaws 10 and 11 are preferably mounted on the rod 6, so as to turn about it, the rod 6 thus serving as the pivot for this set of jaws. While in the preferred construction both jaws are pivotally mounted on the rod, it is of course obvious that one of the jaws might be fixed on the rod, in which case the rod would turn in hearings in its supporting-guides. In the same manner the rod 7 serves to support the pair of manipulatorjaws 14 15, these jaws being also provided with operating-levers 12 13, said levers being also preferably formed integral with the manipulator-jaws.

The means by which the sets of manipulator-jaws are swung about their pivots to roll the cigar-bunch may be widely varied. In the machine shown the guides at are provided with slots 16, and the guides 5 have similar slots. Passing through the slots 16 of the guides 4 5 are operating- rods 17 and 18. These operating-rods are mounted so as to have a rotating movement. \Vhile this rotating movement may be accomplished in various ways, it is preferably effected by mounting the ends of the rods in crank-arms 19, these crank-arms being secured to short shafts .30, which extend through the side frames of the machine. There are preferably tour of these short shafts 20, two at each end of the machine, and each of these shafts is provided with an operating-pinion 21. These operating-pinions 21 preferably mesh with gears 22, mounted on the main shaft 23 ofthe machine, which shaft also finds its bearings in the side frames, before referred to, the gears operating to turn the pinions at each end of the machine in opposite directions. Vith the construction so far described it is obvious that as the pinions 21 and the shafts of the operating-rods 17 18 rotate the rods will he carried around in circular paths and will cause a swinging movement of the guides at 4 and 5 5 about their pivots 3, this movement being permitted by the slots in the guides before referred to, through which the operating-rods pass. Inasmuch as the supporting pivot-rods for the manipulator-jaws are carried in the guides 4c -t and 5 5, it is obvious that they will also have a swinging movement, and the manipulator-jaws are so arranged that said swinging movement takes place about an axial. line which passes substantially through the center of the space inclosed by the closed manipulator-jaws.

It will he noted that the manipulator-levers 8 9 and 12 13, instead of being forked, as in the patent referred to, are formed with asingle leg or extension, the inner sides of said legs or extensions being provided with camfaces 8, B", 12', and 13. The levers 8 9 are located on opposite sides of the operating-rod 18, before referred to, and in the same manner the levers 12 1 3 are arranged on opposite sides of the operating-rod 17. By forming the operating-levers 8 J and 1:2 13 with a single leg or extension in the manner described and providing them with canrfaccs it will be seen that as the operating-rods 1718 in their revolution operate the guides 4 5 4 5, in which the rods 6 7 are mounted, they will in their upward movement come in contact with the cam-faces 8 9' 12'13 and force the levers apart, thus opening the manipulator-jaws carried by the levers. The levers 8 9 1f. 13 yield to the action of the operating-rods by reason of the fact that they are pivotally mounted, and it is obvious that the amount of this yielding action must be properly controlled. While this result may be effected in various ways, it will preferably be done by conneoting the lower ends of the levers of each set of jaws by springs. In the machine shown the levers 12 13 are connected by springs 25 and the levers 8 9 by springs 24. These springs thus control the amount of opening movement of the jaws and hold the cam-faces of the levers snugly against the operatingrods. As, therefore, the operating-rods 17 18 in their revolution move away from the rods 6 7 the springs 21 25 will operate to close the IIS manipulator-jaws upon the cigar-bunch which has been placed therein. Hy substituting this yielding closing action for the positive action before used the manipulator-jaws are enabled to close to a greater or less degree, the amount being determined by the diameter of the cigar-bunch. The manipulatorjaws will thus always firmly grasp the bunch, even though the bu nch varies in size.

\Vhen a fresh hunch is to be placed in the machine or a bunch already rolled is to be removed therefrom, both sets of manipulatorjaws must be opened. \Vhile this may be accomplished by mechanism which varies Widely in construction, the machine shown is arranged, through mechanism which is to be hereinafter described, to always stop so that one set of jaws-namely, the jaws carried by the levers 12 13-wil1 be open. Mechanism must therefore be provided to open the other set of jaws. \Vhile this mechanism may also be varied widely in character, this operation will preferably be effected by a mechanism which is independent of the other devices for operating the jaws. In the preferred form the levers 8 and 9 of the set of jaws 10 and 11 has connected thereto a pair of pivoted links 26 537. The lever 8 is provided with an eye 28, through which passes a bolt 29, the said bolt thus serving to pivotally connect the link 26 to the lever. In the same way the lever 9 is provided with an eye 30, and the link 27 is pivotally connected to it by means of a bolt 31. The two links 26 27 are pivoted together at their outer ends by a bolt 32, said links thus forming a toggle. It is obvious that pressure in an upward direction upon the ends of the links 26 27 will cause the toggle formed by the links to straighten and the levers 8 and 0 to be spread apart, thus opening the set of jaws 10 and 11, controlled by them. The end of the bolt 8; which secures the toggle-arms together moves in a grooved block 32', which is mounted on a stud 32, carried byone of the arms 5. Accurate movement of the toggle is thus secured.

Pressure may be brought upon the links 26 27 by any suitable or desired mechanism. The machine is, however, preferably provided with an arm 33, said arm being pivoted upon a short shaft 34, which finds its bearings in blocks 55, rising from the bed-plate of the machine. The arm 33 has a bearingshoe 136 (see Fig. 5) secured thereto or formed integrally therewith and has its under side provided with a curved bearing-surface 137. The curved bearing-surface 37 of the arm 33 is arranged to be struck by a small strikerarm 38, said arm being secured to a way camshaft IU, which finds its bearing in the frame of the machine and is provided with any suitable operating meansas, for instance, a crank-handle 40. \Vhen the shaft 3!) is operated through the crank-handle 40, it will be seen that the striker-arm will force the arm against the toggle formed by the links and 27, thus breaking the toggle, forcing the levers S and 9 apart, and opening the jaws l0 and 11. An operating mechanism for the jaws is thus formed which is entirely independent of the other operating mechanism for the jaws. By thus opening the jaws by an independent mechanism a much simplerdevice can be used to effect the opening,

and at the same time the rods on which the jaws 10 and 11 are mounted can be made stationary in the carrying-guides 4 5 instead of moving therein, as in the former constructions.

Any suitable means may be used for trimming the ends of the formed bunch. Inasmuch as the machine shown is intended for making cheroots. two trimming-knives 41 are preferably provided, one for each end of the bunch. These knives 41 are carried on curved arms 42, said curved arms being sooured to a sleeve 43, which is mounted on the short shaft 34, before referred to. The sleeve 43 has projecting therefrom a pair of short arms 44, said arms having pivoted between them a lever 45. This lever 45 has a pro jection 46 thereon, said projection being arranged to be engaged by the edge 47 of a cam 48, secured on the cam-shaft 1h). The lever 45 is held in position so that its projection will be struck by the edge 47 on a cam 48, mounted on the shaft 39, by means of a spring 49. Mounted in the outer end of the lever 45 is a screw 50, which runs on the surface of the cam 48, the purpose of the screw being to determine the length of time during which the edge 47 remains in contact with the projection 46, and thereby the throw of the knifecarrying arms 42. After cutting the cigar the knife-carrying arms are retracted by means of a spring 51, a suitable stop, as 70, being provided to limit the backward movement of the arms.

The rolled cigar-bunch may be removed from the manipulator-jaws either by hand or in any suitable manner. In the machine shown a pair of lifting-arms 5'. are shown, these arms being normally located beneath the manipulator-jaws and being mounted in a shaft 53, which is supported in the side frames. The shaft 53 is provided with an arm 54, which is in the path of and struck by an arm 55 and mounted on the shaft 39.

The main shaft 23 of the machine, and consequently the gears 22, may be rotated in any suitable manner and its rotation stopped in any suitable manner after the rolling of the bunch is completed. In the machine shown the main shaft is provided with a belt-pulley 56, which is loosely mounted on the said shaft, and the hub 57 of which is provided with a notch 58. This notch is arranged to be engagcd by a pawl 59, pivoted to one of the gearwheels 22, said pawl being normally held in engagement with the notch 58 by means of a spring 150. Located in suitable bearings on the side of the machine is a bell-crank (i1 62, the arm 61 of which is arranged to be normally out of the path of rotation of the pawl 59, but which whenever it is desired to stop the machine can be thrown into the path of rotation and act upon the tail of this pawl, thus disengaging the pawl from the notch 58. In order to effect the movement of the bellcrank, its arm 62 is in the path of a lever 63, said lever being pivoted to the side frame of the machine at iii. The other end of the lever 63 is preferably provided with a friction-roll 65 and is in the path of a cam 66, which is mounted on the cam-shaft 31). The cam 66 operates to normally hold the inner end of the lever 63 against the arm 62 of the bellcrank, and thus hold the arm 61 out of the path of the pawl 59. A spring 67 is connected to the arm 62, the said spring operating in opposition to the lever 63. When, however, the cam 66 is rotated, thus allowiugthe lever 63 to move, the spring 67 throws down the inner end of the arm 62, thus forcing the arm 61 into the path of the pawl and disconnect ing the belt-pulley from the shaft. A stop 08 is secured. to the gear 22, which stop is arranged to come into contact with the end of the arm '61, and thus stop the rotation of the said gear and the movement of the parts of the machine operated therefrom.

It is to be understood that the mechanisms by which the operations before described are effected may be widely varied, that some of the improvements may be used without the others, and that such independent use of some of the features of the invention is contemplated. The invention is not, therefore, to be limited to the constructions and mechanisms hereinbefore described.
