CORPORATION OF OHIO.
Application filed June 17, 1922.
Our invention relates to cigar bunching machines generally and particularly to certain improvements in machines of this type now universally in use. Generally speaking a cigar bunching machine comprises tobacco hopper, a matrix slide by Which the filler is taken from the hopper in measured quantities and presented before a rolling table, a plunger by Which the filler is discharged from the matrix into a pocket formed by the rolling apron, means for operating the rolling apron to form the bunch7 a bunch carrier into which the apron discharges, a mould carrier supporting a mould to which the bunch is presented by the bunch carrier and means for discharging the bunches from the bunch carrier into the mould.
@ur present invention has for its objects to improve the construction of some of the parts of the machine and to add features thereto which ivill not only improve the operation of the machine but also the finished article produced thereby.
One improvement forming the subject matter of our present invention is the material feeding mechanism. Heretofore difficulty has been experienced in positively feeding the tobacco to the matrix in uniform amounts and our invention is designed to overcome such deficiencies encountered in mechanisms heretofore used.
The material is placed in a hopper or containeu and is fed horizontally by a pair of screws driven by a suitable driving` mechanism. Because of the inconsistent nature of the material We provide adjacent the delivery ends of the screws a pair of Wings or arms which are adapted to oscillate, thereby shaving ofi the material Which clings Within the screws. These oscillating arms or wings preferably derive their motion from the recil'irocating plunger usually employed to eject the lille-r from the matrix onto the rolling apron. The reciprocating arm carries a pair of rollers which cooperate with a pair of slotted arms foi med on the oscillating Wings or arms whereupon reciprocation of the arm cscillates the Wings and produces the desired uniformity in feeding of the material.
Another feature of our improved structure relatts to the construction of the matrix or measuring device. In cigar bunching machines a matrix is mounted for re- CIGAR-BUNCHING MACHINE.
Serial No. 569,052.
ciprocation beneath the hopper and is provided With an aperture into which the tobacco from the hopper is forced. Heretofore however it has been difficult7 owing to the inconsistency of the tobacco, to fill the aperture or shaping cup of the matrix uniformly. Particularly is this so when the shaping cup is of small dimensions as in this case the material has a tendency to arch across the smaller portions of the aperture resulting in an inconsistent density of the material throughout the shaping cup.
Therefore our invention contemplates the provision of a matrix or measuring device of such a construction whereby the Width of the aperture, When the measuring device is readyfor filling, may be increased so that the material forced therein may readily find its Way into all parts of the matrix. Thereafter the size of the aperture Will be decreased to its normal size thereby insuring a uniform compactness of the material contained therein.
Our improved structure further contemplates the provision of what is known as a binder stretcher or binder smoother. In cigar bunching machines the binder is usually placed upon the bunch rolling table. and means .provided for stretching the binder during the rolling operation. Howevermechanisms heretofore used have proven in` eflicient due to the fact that they tended to tear or mutilate the binder and to move the binder from its proper position Which caused p the bunch to be incorrectly rolled.
Our invention therefore contemplates the provision of a binder stretcher mechanism which includes a revolving brush .vhich Will smooth the binder and stretch the same Without tearing or mutilating it. Furthermore the construction of the binder stretcher mechanism is such that it is automatically moved away from the rolling table thereby giving the operator unhampered access to any part of the rolling table so that the binder may be easily and conveniently placed in its proper position upon the table. Furthermore the arrangement of the parts is such that the brush is brought down upon the binder at an early stage of the rolling operation thereby operating efficiently in cases Where small binders are used.
In cigar bunching machines a mechanism is employedl which is known as a bunch car- Cil rier and has for its purpose to catch the bunch after it has been rolled and to convey it to a convenient position for depositing it into the mould. Heretofore n echanisnis of this type have been inei'iicient because they were slow to close after receiving the bunch, thereby permitting he binder to loosen from the tiller and also by reason of the fact that they necessarily held the bunch so tightly atthe momentwhen it as being deposited into the mould, that the binder was injured because of the friction of the carrier on the bunch and because of the pressure of the plunger which was necessary to push the bunch through the carrier into the mould.
Therefore it is an object of our invention to forni the carrier of a pair of spring jaws under tension together with means whereby they are opened atthe time the bunch is discharged from the rolling table into the jaws and whereby the spring' instantlyY clamp the bunch after it is deposited therein, thereby preventing the binder from unravelling and giving the bunch a smooth uniform appearance. Furthermore our structure contemplates the provision of means whereby the spring pressure of the jaws is released at the instant the plunger ejects the bunch from the jaws into the mould, thereby eliminating a large amount of the frictional resistance usually offered to the bunch at the momentof its ejection. Consequently need for excessive pressure of the plunger for ejecting the bunch from the jaws into the mould is eliminated and the tearing of the binder at the point where the plunger comes in contact therewith is prevented.
lVith the foregoing objects in view our invent-ion consists in the novel arrangement and construction of parte which will be made more apparent hereinafter in the acA companying specification and claims and in the drawings wherein Fig. l is a perspective view of a cigar bunching machine embodying our improved features,

YWhile 'we have illustrated trie improvements which form the subject mattei' of this present application as applied to a particular type r cigar bunching machine it .stood that we do not wish to be unnecessarily limited and thereby reserve the right to embody these improven'ients in any of the cigar bnnching machines now on the market and to which these iii-iprovcmcnts may be applicable.
For further detailed description of the constitucion and operation of this general type of cigar bunching machine reference is hereby made to United States Patent No. (372,996 da 'ed pril 16th, lQOl.

These wings are formed in!` ,Vj ally with or rigidly secured to sleeves Z6 which extend through the front of the hopper 2O and are journaled therein. These sleeves receive and support the forward ends of the sha ts 23. Secured to the sleeves upon the ends which project outside the hopper Q0 is a. pair of arms 27 formed with slots 28 extending to one end thereof. Secured to a reciprocating arm 69 (hereinafter referred to) is a bridging` member 29 which carries a pair of stud rollers 30 which rollers are adapted to enter the slots Q8 and in ve longitudinally therethrough. (See particularly 2.)
As the arm G9 reciprocates the slot arms 2T will be oscillated and through the medium of the sleeves 2G, will oscillate the wingsl 27 to slice ed the material which clings upon the forward end of the screws 24.
Adjacent the front end of the hopper is a. plunger 3./ carrying a tamper which plunger and tamper reciprocate inside he hopper 20 to eject the material through the liu is a matrix guided in side guides discharge opening'2l. This tamper mechaemployed.
Any suitable mechanism may be employed for rotating the screws 24 and for reciprocating the tamper and plunger arm and as this specific mechanism forms no important part of our present invention we will only briefly refer to the same. For rotating the screws 24 there would preferably be keyed to the rear end of the shafts 23 gears 84 which intermesh as clearly shown in Fig. 5, one'of which gears would have power applied thereto by a pinion gear keyed to a power shaft 3G operated in some suitable manner from the power shaft of the machine. For reciprocating the tamper and plunger arm we wouldpreferably employ a mechanism similar to that illustrated in United States atent No. 1,002,655 dated September 5th, 1911, in which a rocker arm 87 is pivotally connected intermediate its length to a bracket 38 secured to the hopper 20, the forward end of the roc-ker arm 37 being pivotally connected as at 39 to the upper end of the plunger 32. The rear end of the rocker arm 37 being pivotally connected as at 40 `to a vertically reciprocating arm 4l the lower end of which carries a roller 42, which arm is normally pressed downwardly by a spring 423 bearing on the one end against a collar 44 and on the other end against the bracket A. cam wheel 44 connected to the power shaft of the machine anil provided with a series of cam surfaces 45 periodically acts upon the rod 4l to successively shift the same against the action of the spring 43 whereupon a series of reciprocation is imparted to the tamper plunger 32 and the bridging member 29.
Slidably disposed beneath the hopper 2O 47 formed on the machine. rihe matrix is formed with an opening or shaping cup 48 provided with a rigid side wall 49 anda side wall composed of a plurality of independently adjustable sections in the form of tumblers The independent adjustment of the tumblers 50 is accomplished by bolts 5l which pass through a bar 52 and into the tumblers 50 and are provided with heads 5B and lock nuts 54. By properly adjusting any of the bolts 5l the associated tumbler may be advanced toward or moved away from the rigid wall 49 and the shape and site of the shapingcup varied accordingly. The tumblers arelocked in position by the lock nuts 54.
flerinanently attachel to 'the bar 52 at each end thereof is a rod which rods pass through bearing` lugs 56 formed upon the frame 47. rlhe other end of the rods are connected by means of coil springs 57 to` pins or lugs projecting from theside of the matrix. lfhe rods 55'also carry adjustable lock nuts 59 which in one position abut the lugs 56 shown clearly in Fig. 7.
Mounted immediately over the stationary side 49 of the shaping` cup is a knife or blade (SO secured thereto by bolts or the like 6l. Secured to the underside of the hopper 2O and adjacent the edge of the discharge opening 2l. and cooperating with the knife 6() yis a second blade or knife 62.- These knives are adapted to shear olf the surplus tobacco as the matrix moves towards its discharging position, part of which surplus material has bulged up when the matrix has been contracted.
In 7 the shaping cup or opening 48 is indicated in its greatest maximum open position. and this is accomplished by reason of the matrix receding, the movement of the bar 52 and the tumblers being arrested when the lock nuts 59 engage the lugs 5G. In this manner the matrix body 46 continues to recede, at the same time stretching the springs 57. In this position the opening or shaping cup 48 is positioned beneath the discharge opening 2l of the hopper 2O and when a charge of tobacco has been deposited in the yopening 48 the matrix is then moved forward or toward the left as viewed in F ig. 6 so as to position the opening 48 of the matrix inits discharging position. On the forward movement of the matrix 46 the rigid wall 49 thereof continues itsmovement toward the side formed by the tumblers 50 until the end pieces 63 engage the bar 52, whereupon the opening 4S has been reduced to its minimum size and the tobacco therein has been suitably compressed. Gbviously the knives or blades G0 and 62 cooperate to shear off the excess tobacco which has been deposited in the opening 48 and also that which has bulged up by reason of the reduction of size of the opening. Thus the density of the charge in the shaping cup 48 is uniform and consistent.
For reciprocating the matrix 46 there may .be provided a .pair of lugs 64 to which is pivotally mounted a link 65 connected to an arm 66 operated by a suitable cam on the drive shaft of the machine.
Referring now more particularly to Figs. 2, 5, 6, l0, l1 and 13, the binder stretcher mechanism will be described.
As the matrix 4G is moved forwardit is positioned over a pocket formed by a die 66FL and an apron 6T. The filler is ejected from the opening 48 by. a plunger' G8 carried by an arm F9 which. is reciprocated at the proper time to deposit the filler in the pocket adjacent the edge of the rolling table. The rolling tabie is indicated by the reference character 70.
Rig-idly secured to the frame of themachine is a cam plate 7l provided with a recess or depression 72 and cam surface 73.
Rigidly secured to the cam plate 71 and pro- `iecting downwardly at an angle therefrom is an arm 7 4 to the other end of which there is pivotally connected as at 75 a rocking cam 76. The lower end of the rocking cam 7 6 normally rests on a bumper strip 7'7 secured to the cam plate 71 and the movement of the rocking cam '76 is limited in the other direc- -tion by a. stop 78. Both the bumper strip 77 and the stop 78 may be of a resilient nature so as to eliminate unnecessary noise. 79 indicates (see particularly Figs. 6, 1() and 11) a plate projecting from the hopper 2O through which the plunger 68 projects.
The reference character 8() indicates a pair ot' rocker arms pivoted to the Jframe of the machine so as to swing about the same center as that of the arc otl the surface of the rolling` table. The ends of the respective rocker arms have bearings 8l which support a shaft 82 which carries a roller 83 over which the apron 67 is adapted to pass.
The rocker arms 80 support the binder stretcher mechanism by means of right and left hand supports 8a which are secured rigidly thereto by means of bolts 85. Each supportY 8l is formed with a lug upon which the binder stretcher 'frame 86 is pivotally secured at 87. The frame 86 at one side thereof is provided with an arm 88 carrying a stud roller 89. Supported in suitable bearings 90 carried by the trame 86 is a brush shatt- 91 which carries a brush 92. The end oi the. brush shaft 91 carries a pulley 93 while the end of the shaft 82 is provided with a pulley 94. An elastic belt 95 passes around the pulleys 93 and 9a and over an idler pulley 96a carried by the frame 86. Thus when the shaft 82'rotates this rotary motion is transmitted to the brush shaft 91 thereby rotating the brush.
Each support 84 has aiiixed thereto lugs 96 which support adjusting bolts 97 which engage bumper blocks 98 which may be of a resilient nature. Thus by adjusting the bolt 97 the height of the rotating brush may be reguiated and consequently the pressure the brush exerts upon the binder. These bolts 97 furthermore regulate the movement of the frame 86 and brush 92 so as to keep the stud roller 89 in position to engage the rocking cam 76.
lith the parts in the position illustrated in Fig. 11, that is with the stud roller 89 resposing in the cam recess 72, the frame 86 is swung about its point of pivotal suspension 87 so that the brush 92 is raised away from the table and clears the projection 79. As the rocker arms 8O move forward over the table with the roller 83 to roll the bunch B which had previously been deposited in the pocket formed in the die 66, the binder stretcher trame 86 is moved away from the cam plate 71 and consequently the stud roller 89 rides out of the recess 72 and on the cam face 73. The shape of this cam face is such that the brush 92 is permitted to quickly descend upon the table in advance of the roller 83. As is customary in these machines a binder has been previously laid upon the table and therefore the brush 92 bears upon the binder immediately in front of the filler around which the binder is being wrapped. Owing to the movement of the apron 67 the roller 83 is being rotated and consequently the 4shaft 82 whereupon the rotary motion is applied to the brush 92 through the medium of the pulleys 94 and 93 and the elastic belt 95. This rotary motion ot' the brush smooths the binder and exerts enough pressure on it to stretch the saine. As hereinbefore mentioned the pressure exerted by the brush 92 may be regulated by adjusting the bolts 97. As the binder stretcher frame ioves toward the end of the table the stud roller 89 engages the rocking cam 76 and during the continued movement o1c the frame rocks the rocking cam 76 so that the stud roller 89 may clear the upper end thereof. As the stud roller 89 clears the upper end of the rocking cam 76 this cam assumes by gravity the position illustrated in Fig. 10. Upon the return movement of the binder stretcher frame the stud roller 89 engages the under side ot the rocking cam 76 and rides along` the same. As the stud roller 89 passes the point of pivotal connection. of the rocking cam it raises the said cam to the position illustrated in dotted line in Fig. l() that is until the rocking cam 76 abuts the stop 78. In this position the rocking cam directs the stud roller 89 into the recess 72 whereupon the rocking cam 76 again drops by gravity to the position illustrated in full .lines in Fig. 10. Obviously with the stud roller 89 again reposing in the recess 72 the binder stretcher frame together with the brush is moved up clear of the table 70 so that the operator can conveniently place a new binder upon the table ready for the next operation. The ends of the apron 67 are preferably attached to a pair ot controlling levers 98 and 99 suitably controlled by cams on the power shaft of the machine.
As hereinbefore mentioned after the rotating brush 92 has dropped upon 'the binder itmoves forward relatively in advance of the bunch being rolled, smoothing the binder and holding it taut, thus giving the bunch a smooth uniform appearance.
As the apron 67 rolls the bunch to the edge of the table 70 it is discharged therefrom and caught by what is known in the art as a bunch carrier, which conveys the bunch to a convenient position for depositing it in the mould. This bunch carrier must grasps the bunch immediately so as to prevent the same from unravelling.
The bunch carrier consists of a stationary jaw 100 formed integrally with a slide 101 which moves in a horizontally disposed slideway 102, the reciprocatory movement of which is accomplished by means of a link 103 suitably actuated by a lever 104 controlled by a cam on the power shaft of the machine. Cooperating with the stationary jaw 100 is a movable jaw 105 formed with a shaft 106 which is mounted in the bearing 107 carried by the stationary aw 100. Spring means such as the coil spring 10S is provided which exerts a pressure tending to move the jaw 105 to a horizontal position and toward the stationary jaw 100.. lli bumper block 109 is formed upon the movable jaw 105, one portion of the bumper block 109 being cutl to form a cam surface 110.
One of the rocker arms 80 has mounted thereon a bumper pin 111 which is adjustably held by a lock nut 112. The bumper pin 111 is adapted to engage the bumper` block 109 as the arm swings over the edge of the rolling table 70. Thus just prior to the time that a bunch is discharged into the jaws 100-105 the bumper pin 111 engages the bumper block 109 and swings the movable jaw 105 from the stationary jaw 100 and against the tension of thc spring means 108, thereby enabling the bunch to be easily deposited between the jaws. However the movement of the arm 80 is immediately reversed and the movable jaw 105 permitted to again move toward the stationary jaw 100 whereupon the bunch is caught and positively held thereby preventing an unravelling of the same.
In the operation of the machine the jaws 100- 105 move toward a mould 112@ which is successively fed step by step to present the mould recesses 113 beneath the bunch carrier 100-105. Thereupon a plunger 114: carried by an arm 115 and reciprocated by suitable mechanism is adapted to eject the bunch from the bunch carrier into the mould recess disposed thereunder. The plunger 114 has formed thereon a tinger 115a which acts as a cam and cooperates with the cam surface 110 formed on the block 109. The position of the finger 115 is such that it engages the cam surface 110 just prior to the time the plunger 114 enlgages the bunch B so that the movable jaw 105 is moved away from the stationary jaw 100 thereby permitting the bunch B to be ejected from between the jaws without necessitating any considerable amount of pressure and eliminating the possibility of tearing or injuring the bunch.
Obviously therefore means are provided whereby the bunch carrier is open just prior toits reception of the bunch and closes immediately so as to properly hold the bunch and prevent the binder from unravelling. Furthermore it is obvious that just prior to the eject-ion of the bunch from between the jaws and into the mould the jaws are aga-in moved apart so that the bunch and binder will not be injured by friction and an excessive pressure need not be eX- erted by the plunger 114C in ejecting the bunch.
As hereinbefore mentioned the operation of the machine as a whole has been described only in so far as its operations effeet the improvements forming the subject matter of our present invention.
