Definitions
- This invention relates to the manufacture of cigars and is more particularly concerned with an apparatus and a method for pressing or shaping cigars, more specifically for imparting flat-sided characteristics to cigars normally formed with a circular cross-section.
- each cigar to be shaped a radially-inwardly directed pressure from four equally spaced directions and these pressures are applied to give the cigar a flat or preferably .a slightly concave configuration on each of its four sides receiving the pressure.
- This pressure is continuously applied for a predetermined period of time and then released. Upon release of the pressure, the sides of the cigar gradually spring out a little and the cigar finally assumes the desired, substantially fiat-sided configuration.
- the apparatus for this operation comprises .a compressing unit defined by an assembly of four radially movable jaw elements which have flat or preferably arcuate surfaces forming the four sides of an axial aperture which varies in cross-section in response to the radial movements of the jaw elements.
- the apparatus further includes means,
- the apparatus of the invention is adapted for automatic operation when incorporated in a machine which continuously feeds cigars to be shaped and discharges the pressed cigars.
- a series of apparatus units of the construction indicated are mounted on an endless conveyor which brings them sequentially to a charging station where each compressing unit receives .a cigar, a compressing station Where the jaws of each unit are actuated to move radially inwardly against the cigar, a releasing station at which the jaws of each unit are actuated to move radially outwardly to release the pressure on the cigar, and a discharging station at which the shaped cigar is ejected from the compressing unit.
- the conveyor carrying the compressing units is, .of course, actuated by any convenient means in timed relationship with suitable supplying means for introducing a cigar to the axial aperture of each unit as it is brought sequentially to the charging station and simultaneously with discharging means for removing a pressed cigar from each unit as it reaches the discharging station.

- FIG. 9 is a top plan view of the same machine shown in FIG. 7;
- FIG. 9A is a partial View of only the charging and discharging end of FIG. 9 modified to show different means for discharging shaped cigars from the machine.
- compressing unit 10 comprises two end walls 12 which are interconnected by lower horizontal brace '14 that has its ends fitted in grooves 15 and screwed to walls 12.
- FIG. 6 shows that each end wall 12 has a circular aperture 16 from which radiate four equally spaced rectilinear slots 18.
- each end wall 12 rotatably supports two rollers 20.
- Four jaws 22 extend between end walls 12 and each jaw is provided at each of its ends with a flat-sided protrusion or head 23, FIG. 1, and a pin 24 which are both slidably fitted in one of the slots 18 in an end wall 12 to guide that jaw inwardly and outwardly in relation to aperture 16.
- each end wall 12 Overlying the outer surface of each end wall 12 is a cam plate 26 which, as seen in FIG. 5, is formed with a central circular aperture 28 that is aligned with aperture 16 of th associated end wall 12. Cam plate 26 also has four arcuate slots 29 positioned around aperture 28, these slots being dimensioned to receive pins 24 of jaws 22. Also overlying the outer surface of each end wall 12 is an end support plate 30 which is secured, as by screws, to its associated end wall 12 and which has a circular recess 33 in which a cam plate 26 is rotatably fitted.
- a circular aperture 32 in support plate 3t) may have the same diameter as that of cam plate 26.
- aperture 32 is of slightly smaller diameter than that of cam plate 26 and thus forms with circular recess 33 on the inner side of support plate 30 a circular lip that holds cam plate 26 against outward axial displacement.
- FIG. 1 shows cam plate 26 at the limit of its clockwise rotation; in this position, pins 24, and thus jaws 22 to which they are attached, have been moved radially closer to the axis of central aperture 28.
- pins 24 are moved radially away from aperture 28 so that jaws 22 are in the open position illustrated in FIG. 4.
- pins 24 and associated jaws 22 will move radially inwardly or outwardly to decrease or increase, respectively, the size of the axial space 34 defined by the four jaws 22, as seen in FIGS. 3 and 4, which space is, of course, axially aligned with apertures 16 in end walls 12 and apertures 28 in cam plates 26.
- each lever arm 35 has an aperture 36 which is an alignment with the other apertures previously mentioned.
- ends 38 of arms 35 are interconnected by rod 40 which, in the embodiment illustrated, supports rollers 42 adjacent each lever arm 35.
- rollers 42 as well as that of rollers 20, will be described below.
- a reinforcing bar 43 also interconnects and is secured to lever arms 35 to insure accurate synchronized movement of the arms.
- each jaw 22 is formed with a central body portion 45 and end flanges 46 which carry pins 24. Jaws 22 must be able to with stand substantial forces tending to bend or how them outwardly when a cigar is being pressed. Jaws 22 can be of uniform thickness between end flanges 45 but, in order to reduce Weight, they are preferably formed with a greater thickness at the center and this thickness tapers down toward end flanges 46 as seen in FIG. 2.
- the surface 48 of each jaw 22 which faces axial space 34 is preferably, as shown in "FIGS. 3 and 4, outwardly arcuate or convex.
- All of the jaws may have the same width and the same radius of curvature but, as illustrated, one opposite pair may be wider than the other pair and may have a different radius of curvature from that of the other pair.
- the choice of variations in jaw width and surface curvature depends upon the dimensions desired in the finished cigar.
- the arcuate slots 2? in cam plates 26 may be so disposed as to move radially inwardly one pair of opposite jaws 22 more than the other pair; in this way, the cross-section of the pressed cigar can be made generally rectangular rather than square.
- the distance of inward movement of each jaw 22 is controlled by the curvature of the arcuate slots 29 into which its pins 24 project and by the position of these .slots relative to the axis of cam plate 26.
- cigars of any style have a predetermined size and are all of substantially the same circumferential dimension.
- the jaws must be arranged, therefore, to accommodate the cigar in its initial form and to move a sufiicient distance inwardly to compress the cigar.
- the distance or" travel of the jaws toward each other and the curvature of their surfaces are factors in determining the time during which the cigars need to be held under compression. As a general rule, for a. given distance of travel, the less the radius of curvature is, the more rapid the shaping will be, but the radius of curvature should not be so small that the cigar is so sharply compressed that it is damaged.
- the jaws and the associated arcuate slots in the cam plates are constructed to permit the jaws to move apart to a point at which the dimensions A and B shown in FIG. 4 between the innermost points of the opposed surfaces of each jaw pair is inch and to permit the narrower lateral jaws to move inwardly to a point at which the dimension A is reduced to /2 inch and simultaneously to permit the wider vertical jaws to move inwardly to a point at which the vertical dimension B is reduced to inch.
- the cigar to be shaped has a circular cross-section with a diameter of inch.
- an important practical aspect of the compressing unit of this invention is that a plurality of such units can be combined with an endless conveyor so that each unit is passed through a series of stations at which it first receives a cigar, is closed to compress the cigar, is opened to release the cigar, and has the cigar discharged from it before it returns to the initial charging station to repeat the cycle.
- the conveyor, the charging means, the closing means, the opening means, and the discharging means may take various forms.
- FIGS. 7 to 9 an illustrative system for effectively utilizing the above-described cigar compressing units in a continuous cigar pressing operation, but it will be understood that many variations may be made in the system illustrated.
- an endless conveyor is formed from a pair of chains 50 carried about a pair of sprocket wheels 52 and 53 at opposite ends, the latter pair 53 being driven from any convenient source of power,
- each unit 10 is suitably fastened to brackets 60, FIGS. 1, 2 and 8, which are connected to chains 50. It will be seen that the end of each compressing unit 10 visible in FIG. 7 is opposite the end seen in FIG. 1. Consequently, the jaws open upon clockwise rotation of lever arm 35 visible in FIG. 7 and close upon counter-clockwise rotation of the lever arm.
- side rails 62 parallel to the chains to receive rollers of compressing units 10 in order to relieve the chains from the weight of the units in this part of the machine.
- cam rails 64 Leading ends 66 of cam rails 64 are gradually tapered in order to effect gradual closure of the jaws of the compressing unit that has been just charged with a cigar. Cam rails 64 continue throughout the upper run of the conveyor and thus positively hold that jaws closed. A similar pair of cam rails 68 engage rollers 42 along the lower run of the conveyor to hold the jaws shut. A pair of side rails 63 parallel to the lower run of chains 50 is disposed to receive rollers 28 of compressing units 18 in this part of the machine and thus relieve the conveyor chains of this load.
- fixed bumpers 70 are positioned to engage the lower portions 72 of the two lever arms of each unit to cause these arms to rotate in a direction to open the jaws, which is clockwise as viewed in FIG. 7. Bumpers 70 are of a length to hold the jaws of units 10 open while these units are in discharging station D and charging station C.
- Feeding of the cigars to charging station C is conveniently efiected by means of a second conveyor 75 which is driven by gearing (not shown) in synchronism with conveyor chains 50 but in the opposite direction.
- Two conveyor chains 75 carry a series of channels 77 which are of a suitable size to hold a single cigar.
- a channel 77 is in alignment with a compressing unit It) at charging station C.
- Channels 77 are loaded with cigars by any convenient means 78 such as a hopper at the right-hand end of the machine as seen in FIGS. 7 and 9.
- plungers 80 and 81 are provided, although it will be understood that other charging and discharging means may be used.
- Plunger 80 is positioned to move through the channel 77 stopped at charging station C until the cigar therein has been pushed into axial space 34 of the compressing unit 10 at station C.
- a back-up plunger 82 aligned with plunger 88, moves simultaneously but in the opposite direction but only so far as to stop the injected cigar and thus position it properly along the length of axial space 34 in unit 10.
- a chute 96 receives the discharged cigars and they are removed by any convenient means.
- plungers 80 and 81 are moved by pivoted arms 83 and 90, respectively, which are actuated by cam Wheel 85 containing cam track 88 to etfect the desired movement of each plunger in synchronism with the movements of the two conveyors.
- Cam wheel 85 is driven through gearing (not shown) by the same power source which drives Geneva gear 55.
- a portion of machine frame 87 is shown as providing the bearing support 89 for cam wheel 85.
- Arms 83 and 90 have their pivot bearings 84 and 91, respectively, also supported by frame 87.
- Arm 83 has a cam roller 86 riding in cam track 88 and is pivotally connected at its lower end 93 to tie rod 92.
- the other end of rod 92 is pivotally attached to arm 90 at an intermediate point 94.
- compressing units 10 are eitectively utilized for the rapid and continuous shaping of cigars and that they may be readily integrated with cigarmaking and cigar-packaging machinery to eliminate the laborious and time-consuming pressing operation which has been conventional. It is no longer necessary to store cigars in pressing trays for long periods of time from the moment they have been manufactured to the moment they can be packaged.
- the compressing unit may have an aperture in only one of its end walls for receiving and removing cigars.
- plungers 81 and 82 are not used in the continuous pressing machine and the shaped cigar is removed from the compressing unit by a suction tube 84 having a concave cap 85 on its end conforming with the end of the cigar. 1
- This suction tube is positioned at discharging station D and moves in the manner of plunger 80.
- Flexible hose 86 connects tube 84 with a suitable vacuum source (not shown).
- a compressing unit for shaping a cigar into a v generally flat-sided configuration which comprises a first pair of elongated jaws movable toward and away from each other along a first radial line, a second pair of elongated jaws movable toward and away from each other along a second radial line, said jaws each providing a continuous uninterrupted shaping surface of a length at least equal to the length of a cigar adapted to be received therebetween and of a width such that said cigar is completely surrounded by said jaws in their most inward position, said two pairs being arranged to form an elongated axial space to receive said cigar with said first radial line of movement of said first pair substantially at right angles to said second radial line of movement of said second pair, and means associated with said two pairs to move in synchronism all of said jaws radially toward and away from said axial space.
- a compressing unit for pressing a generally cylindrical cigar to form thereon four substantially flattened sides which comprises an assembly of four elongated jaws each providing a continuous uninterrupted shaping surface of a length at least equal to the length of a cigar adapted to be received therebetween and of a width such that said cigar is completely surrounded by said jaws in their most inward position, said jaws being arranged to form an elongated axial space in which said cigar fits with said jaws being radially movable toward and away from said axial space, and cam means associated with said jaws to move all said jaws in synchronism radially toward and away from said axial space.
- An apparatus for continuously pressing cigars which comprising an endless conveyor, a plurality of com-. pressing units defined in claim 7 mounted on said conveyor, charging means to introduce a cigar into each of said compressing units as it reaches a charging station adjacent said conveyor, actuating means to cause said cam means of each of said compressing units as it leaves said charging station to move said jaws toward said axial space, releasing means to cause each of said earn means that has been acted upon by said actuating means to move said jaws away from said axial space, discharging means an assembly of four elongated jaws each providing a continuous uninterrupted shaping surface of a length at least equal to the length of a cigar adapted to be received therebetween and of a width such that said cigar is completely surrounded by said jaws in their most inward position, said jaws being supported at their opposite ends by a pair of spaced end walls at least one of which has an aperture for passing said cigar tnerethrough, said jaws being arranged to form an elongated axial space in which said cigar fits and said
