31 Claims.

This invention relates to cigar making machines and more particularly to improvements in the crimping and trimming mechanisms of a cigar machine.

The present invention discloses a satisfactory type of crimper for use with a high speed cigar machine. In speeding up the cigar production of cigar machines it is desirable that provision be made for maintaining the cigar between crimper jaws for the same length of time as, if not longer than, has been done with slower operating cigar machines.

It is therefore an object of my invention to provide a means for increasing the length of time a cigar is held in the crimping mechanism without slowing down the operation of the cigar machine.

A further object of my invention is to provide a crimper for use with high speed cigar machines which will not reduce the amount of crimping time.

A further object is to provide a crimper which has eliminated undesirable stresses upon its component parts when in a closed position.

A further object is to provide a simplified crimping device which will occupy a minimum amount of space in the machine.

A further object is to provide a set of stationarv trimming knives of simplified construction cooperating with said crimping jaws.

A further object is to provide a duplex crimpi g mechanism in which there will be such a relative motion of the bunch shaping members at the time of their separation to release the bunch, that the bunch will be sufiiciently loosened from the shapin surfaces to prevent possible injury to the bunch.

A further object is to provide a duplex crimper which will not require any more transfer arms than are used with a single crimper.

A further object is to provide a pair of improved btmch carrier fingers which can be opened by pressure applied at either side of the carrier fingers.

A further object is to provide an improved crimper which requires the moving of only one jaw to allow the insertion and removal of cigar bunches.

A further object is to provide a crimper which will not tear the binder of a cigar as it is inserted between or removed from the crimping jaws.

Other objects and features of the invention will appear as the description of the particular physical embodiment selected to illustrate the invention progresses.

In the accompanying drawings which form a part of this specification, like characters of reference have been applied to corresponding parts throughout the several views which make up the drawings, in which:

Fig. 1 is a side elevation of the improved cigar bunch shaper showing both crimper jaws in a closed position; i

Fig. 2 is a front elevation of the machine in the same operating position as shown in Fig. 1;

Fig. 3 is a cross sectional partial view of Fig. 1 taken on the line 3-3;

Figs. 4 and 5 are side elevations showing the improved cigar bunch shaper in different operating positions, with Fig. 4 also showing the bunch delivering fingers inserting a cigar bunch between the jaws for crimping;

Fig. 6 is a detailed front elevation of the improved bunch carrying fingers;

Fig. 7 is a detailed side elevation of the fingers in the same operating position shown in Fig. 6;

Fig. 8 is a detail side elevation of the bunch carrier for removing crimped cigar bunches from the crimper; r

Fig. 9 is a sectional front elevation of the bunch carrier shown in Fig. 8; and

Fig. 10 is a cross sectional plan view of the retarding fiber washer and spring taken along the line Iii-l0 of Fig. 1;

Fig. 11 is a side elevation of conventional cam actuated mechanism which may be employed for operating the crimper.

In the embodiment shown in Figs. 1 and 2, the main support block l0 has formed therein an opening 5! which receives a shaft l2 upon which there is mounted an oscillating member l3 which rocks upon shaft I2 during the crimping operation. Stop rollers l4 and 15 are fixed to member 13 by means of studs l6 and H (Figs. 1 and 4). Although the stopping means shown in the present embodiment are rollers, any other conventional stops could also be employed for this purpose.

The upper arm ends of member 13 (Fig. 1) have cam followers 2| and 26 connected thereto which rotate upon studs I9 and 23. A pair of cam followers similar to M and 25 (Fig. 1) are located on the other side of the duplex crimper shown in Fig. 1, and one of said cam followers 22 can be seen in Fig. 2. One of the uprights of member 10 has formed therein an opening 2'! which supports a shaft 28 (Fig. 2).

to one end of said shaft is a crank arm 28.

A rod 35 has fixed to one of its ends a mounting 32 which has provision for the lengthening or shortening of rod 35 by means of a nut 53% (Fig, 2). 1e mounting 32 is connected to one end of crank arm 29 by means of a stud H9, and when an up and down movement is imparted to rod 39 it will cause shaft 28 to oscillate in the opening 2?. On the other end of shaft 28 is mounted a stop head having two rounded portions 33 and two flat portions 34 (Fig. The lower parts 35 and 35 (Fig. 4) of rocking member I3 have shaftways 31 and 38 formed therein for receiving slidable plungers li and 40. In said lower parts 35 and 35 there are mounted friction washers 4! and 42 (Fig. 4). These washers may be composed of a fabricoid or iiber material which is held against the plunger by means of springs 95 and 9|. Any other suitable device might also be employed to retard the free sliding of plungers- 39 and 43 in shaftways 31 and 33 (Fi 4).

Mounted on pivots 45 andv 45, which are fixed to plungers 39 and 40, are levers 43 and 44. Cam

tracks 41 and 48 (Figs. 1, 4 and 5) are provided in the upper ends of levers 43 and 44 whereby the cam rollers 2! and 26 (Fig. l) are guided. A similar set of members having like cam tracks are also found at the rear of the mechanism shown in. Fig. 1. One of the cam tracks 49 can be seen in Fig. 2.

Levers 43 and 44 (Fig. 4) have arms 50 and 5! to which are attached links52 and 53 (Fig. 1) by means of eccentric studs 54 and 55 (Fig. l). The eccentric studs are held fixedly in position by suitable means such as set screws 54 and 55. The eccentric studs 54 and 55 may be turned to either raise or lower links 52 and 53, which movement permits the crimping jaws to be properly aligned with one another. The other ends of links 52 and 53 are movably fixed by means of studs 58 and 59 (Figs. 4 and 5) to the elbow of levers 6i) and M, which levers in turn pivot on studs 62 and 63 (Figs. 4 and 5) mounted in a part of member I3.

Arms 54 and 55 of levers (it) and SI are movably connected to rods 56 and 5'5, which rods may be lengthened or shortened as desired by adjustable means 88 and 6! (Fig. 4). top of uprights I5 and IT (Fig. 2) 'of main support block IIJ are guide tracks It! and I2. Slidably mounted in said tracks are knife holding members '52 and 23 which can be immovably fixed at any desired position along said tracks I by means of clamping screws '54 and I5 (Fig. 2). Knife blades 95 and 95 (Fig. 2') are removably fixed to said knife holding members by means of clamp screws 23 and 19. A similar set of knife blades is located in a similar position at the rear of the device shown in Fig. 2. One of said blades 88 can be seen in Figs. 1 and 3.

Crimping jaw molds iii and 82 (Fig. 2) are removably fixed to the upper part of levers 43 and 44 by means of clamp bolts 53 and 84. Adjusting screws I29 cooperating with clamp bolts .83 and 2-4 provide suitable means for aligning the adjacent swing jaws 8! and SB'Wit-h the jaws 84 and 8'! mounted on the upper part of central member I3 (Figs. 2 and 3). A similar set of crimping molds is located at the rear of the device shown in Fig. one'of which crimping molds can be seen in Fig. 1. Clamp bolt 84 is slidably mounted in slot 33 (Fig. 2) formed in member 44, 44 By loosening bolt 84, the

Formed on til crimping jaw mold 82 can be moved into any desired position to handle different length cigars. Fixed to the upper central part of member I3 is a set of duplex crimping jaws 88 and 8? (Fig. 2) mounted on each side of the central member and cooperating with the swinging jaws 3| and 22 (Fig. 2), and 25 (Fig. l). Crimpings jaws 8-5 and 31 are removably and adjustably fixed to member I3 by bolts 55 and 5l or other suitable means so as to he adjustable for crimping cigars of different lengths.

The crimping jaws above mentioned have molds formed therein which conform to the contour of a cigar. Beds 55, B? and 3B are all operated by suitable means, shown in Fig. 11, from a moving part of the cigar machine forming no part of the present invention, in timed relation with one another. Any suitable cam operating means may be employed for this purpose and reference may be had to such U. S. patents as Wahlstrom 1,442,200, Schussler 1,682,542, Marsh et a1. 1,191,199 and Rundell 1,523,721 for examples of cam operating means. Referring to the cam structure in Fig. 11, which is similar to that shown in U. S. Patent 1,442,200, a cam member I42 is mounted on a shaft I44 driven by suitable means from the main shaft of a cigar machine. Suitable cam tracks I40 and I53 are formed on opposite sides of cam I42 and actuate cam rollers 633 and I 48 respectively which travel in these tracks. Cam lever arms I35, I45 and I52, carrying cam rollers I33, I48 and I54, respectively, are .all mounted upon a common shaft I34 supported in a stationary bracket I32. The cam roller I54 rides on the periphery of cam I42 and receives actuating movement from a conventional hump I56 secured to said periphery. In the present' showing, cam roller IE4 is held against the periphery of cam I42 by gravity. Spring means could of course be used to supplement the force of gravity to bias roller I54 against said periphery. It is understood that this showing of the cam operating means is for purposes of illustration only since any other suitable operating mechanism may be employed.

.T-he carrying fingers heretofore used in connection with crimping jaws cannot very well be used with a duplex crimper such as the one shown in the present application because they could only be opened by, pressure from one side. For this reason it was necessary to design novel carrier fingers for use with the type crimper disclosed herein which could be opened by pressure from either side of the carrying fingers. The fingers shown in Figs. 6 and 7 can be operated from either side of the crimper. A shaft 59 is journaled' to an arm I25 for holding the carrying gripper fingers in a more or less vertical position at all times, when moving said fingers from a receiving station to a discharging station or vice versa. Fixedly mounted on the shaft 99 is a sprocket wheel I26 over which runs a sprocket chain I21. The other end of arm I25 is fixedly mounted on shaft I28 which in turn is journaled to a suitable bearing bracket I29 which is secured to the frame of the machine. A second sprocket ISO is secured to the bearing bracket I29. The shaft I28 is actuated by suitable mechanism to swing the arm I25 from one station to another during certain predetermined periods of the machine cycle. During these operations the sprocket chain I21 will keep the bunch carrying fingers in a substantially vertical position which is somewhat similar to that shown in my Patent No. 1,786,608.

Also fixedly mounted to shaft 99 by means of clamp bolt I60 is a block IOI having an opening I62 for receiving a spring I33 (Fig. 7) The block "II also has an adjustable stop screw IM mounted therein. Swingingly mounted on the shaft 98 are two fingers 3'! and 98. Finger 98 has an opening I85 for receiving the other end of spring I33 and also a protruding stop I33 which operates against stop screw I04. Normally, sprin I33 will urge finger 98 against stop I54, which stop determines the limit of its forward or closing swing motion. Also pivotally mounted on finger 98 by means of a stud I88 is a latch bar I69 having a pin III] to which is secured a spring II I. There is also secured to finger 98 a plunger II2 which protrudes through and beyond an opening formed in finger 9?. Finger 3? is swingingly mounted on shaft 5' and has a pin H3 fixed thereto to which is secured the other end of spring III. The spring I II will apply latching tension to latch I09 and will also continuously urge fingers 91 and 98 toward one another. Finger 9? has a stop I31 connected thereto which operates against a part of block IfiI to limit the extent of its closing swing motion, functioning in the same manner as the stop .36 of finger 93. Stops ID? and I06 operating against block IIJI limit the extent to which the fingers 97 and 98 can approach each other. nected thereto which projects through and beyond an opening formed in finger 9B.

A bar H5 is fixed to finger 91 and cooperates with the notch IIB formed in latch I39 so as to maintain fingers 9i and 98 in latched open posiu tion by means of this latching device when said fingers are spread apart. It will therefore be seen that fingers 97 and 98 can be latched into open position by pushing either plunger H2. or I It. At the pickup station (not shown), a suitable element is provided to unlatch the fingers by raising bar I89 in order to close the fingers about an uncrimped cigar bunch preparatory to carrying it to the crimpers.

The operation of the present invention may be briefiy described as follows:

With the stop roller 34 resting against the rounded edge 33 of the stop head under the downward pull of rod 6?, suitable bunch carrier fingers such as I22 and I23 (Fig. 9) for removing crimped I ent, No. 1,786,608, granted to me on December 3D, 1930, and a detailed description of the same is therefore not deemed necessary here and has been omitted for the sake of brevity. A cam i=2?! then causes rod 56 (Fig. 4) to ascend. The rod 35 in turn raises lever arm 64 of lever 69 which pivots on stud E2. The elbow of lever 66 in turn causes the upper part of link 52 first to move outward and then upward. Link 52 in turn causes lever 43 pivoting on stud 45 to ascend. Friction washer I retards plunger 39 sufficiently to cause cam follower 26 to track against the inside wall 83 (Fig. 4) of cam track 41 in movin outward.

t will be noted that the crimping jaws move apart with a peeling motion as opposed to a straight upward or outward motion. This peeling like opening prevents a crimped cigar bunch from being split apart because of any sticking of the cigar to the faces of the molds. It is for Finger 9? also has a plunger H4 conobtaining this peeling motion that cam track 41 is shaped as it is.

When the crimping jaws B6 and 85 have been opened up, as shown in Fig. 4, the bunch carrier fingers I22 and I23 (Figs. 9 and gripping the crimped cigar bunch ascend to place the bunch at some other bunch receiving station on the machine. A cam I55 then operates rod so as to cause the stop head (33, 34) to turn slightly and to have its fiat edge 34 face the stop roller I I. This fiat face 34 permits member I3 to rock under the pull of rod 61 slightly farther in the direction of said rod, thus throwing the center 94 of the bunch receiving crimper out of line with the center of shaft I2 and stud 28 (Fig. 4). With the bunch receiving crimper thus out of line, other bunch carrying fingers gripping a cigar bunch (shown in Fig. 4) descend with the cigar to be crimped. Since the bunch receiving jaw is off center, there is no danger of the cigar bunch hitting the edge II! of the crimper jaw 86 on its descent with the cigar bunch. As the cigar bunch is thus held between the open jaws 85 and 86, the rod 66 begins to descend. The rod 66 then pulls the arm E i downward and the elbow of lever 69, to which the link 52 is fastened, causes said link to move inward and downward. The link 52 in turn causes arm 58 to descend which causes lever 43 pivoting on stud also to descend. Friction washer 4| retards the descent of plunger 39 to which the lever 43 is pivotally fixed (Fig. 4). This retarding effect causes lever 43 first to swing inward before beginning its downward movement, and cam follower 25 will therefore follow the outside track 88 of the cam track H, This closing motion, shown by the arrows in Fig. 4, embodies a very satisfactory method for closing a set of crimping jaws about a cigar bunch.

In closing inwardly, the edges of crimping jaw 85 first strike the ends of the cigar bunch C (Fig. 4), the bunch then being momentarily held at the ends by jaws 85 and 86 and also by the fingers 91 and 98. In continuing further its inward closing movement, an upper part of lever 53 strikes against plunger I I2, thereby compressing spring I33 and opening outwardly finger 98 until it is latched by bar I39 in said open position.

It will be noted that finger 9'! has not moved during this time because stop I01 acting against the fixed block II)! has limited the extent of its movement toward finger 98. However, finger 91 at this time is no longer in contact with the cigar bunch C because the jaw 85 has pushed the bunch away from said fingers against jaw 86 in its closing operation.

The fingers 91 and 98 then withdraw while they are thus in latched open position without touching any part of the cigar. A suitable cam I like structure IZ I connected to the upper part of lever I3 and operating against plunger I I2, serves to keep the fingers clear of the cigar while being withdrawn.

Crimper jaws 85 and 36 are locked in their closed position by means of a toggle action.

The stud 58 carried by the elbow of lever is pushed past the dead center line formed by studs 62, 58 and 54, and the elbow of lever 69 comes to rest against a stop I2I connected to member I3. This toggle arrangement will of course permit the opposed jaws to be opened or closed at the end of each rocking movement, and the stop 33, 34 will permit a slight additional rock to take place when one set of jaws is open to facilitate the receipt of a cigar bunch for crimping in a manner heretoforedescribed The opposite set of crimping jaws, .how.ever, 'wil l This arrangement keeps the jaws firmlyilocked.

The rocking movementin. the direction of rod 65,.is broughtto-astop when stop .roller.l5 comes into contact with ,the rounded portion, 33 of the stop head.

It will be noted that a force is exerted upon the adjacent swinging jaws from. a direction die ametricallyopposed to that of the stress exerted 7 upon the central .jaw member, thereby eliminating undesirablecrimping stresses prevailing in crimpers used heretofore which-caused a great deal of wear upon diiierentpartsof the .crimper and frequently resulted in theshaft of the.lower crimper jaw being broken ,ofiduring. the crimp ing process.

It is to be noted thatv only one bunch carrying member is-usedzfor removing crimped cigar bunches from both of the cigar crimper, jaws,- and only one bunch carrying membenis used forinsorting cigar bunchestofbe crimped into both cigar crimper jaws.

A cigar bunch crimper for shaping the ends of a cigar bunch comprising, a central member movable into different bunch receiving" positions and having sets of bunch shaping jaws mounted on opposed sides of said central member; separate sets of bunch shapingjaws' adjacent'tosaid central member, each of which cooperates exclusively with one of the sets of 'jaws' mounted on said central member; and means for bringing each separate set of bunch 'shaping'jaws' in succession into bunch shaping relation 'with'the jaws on said central member by only moving each of said separate sets when said central member has been placed'in a respective bunch receiving position.

26. A cigar bunch shaper comprising, a rocking central member movable into different bunch receiving positions and having bunch shaping jaws mounted on'opposite sides of said central member across the path of its rocking'movement, separate bunch shaping jaws adj acent' to said central member, means for bringingsaid adjacent jaws into bunch shaping relationwith the jaws mounted on said central member by'ohly moving each of said adjacentjaws when" said central member has been placed in a respective bunch receiving positionjandmeans for rocking'said central 'member whilesaid jaws are in bunch shaping relation. 1

27. A cigar bunch shaper for shaping the ends of a cigar bunch comprising, a central member movably mounted upon a support, bunch shaping jaws mounted on's'aid member, separate bunch shaping jaws adjacent to said'central "member and cooperating therewith,'"r'neansfor'bringing said separate bunch shaping 'jaws'intobunch shaping relation with the jaws onsaid central member by only moving said separate bunch shaping jaws and maintaining the jaws on said central member free from movement; means for adjusting the alignment of'said' bunch shaping'jaws. and means for adjusting the degree of'squeeze exerted by said bunch 'shaping'jaws.

28. In a cigar machinefthe combination'with a bunch shaper comprising a stationarysu'pport, of a horizontal member mounted insaid" support; a block mounted on said horizontal; member; a jaw, having a shaping face, mountedzon "said block; a second jaw'adjacent to'said'block and first named shaping 'devicestationary'as the shaprelatively'movable towards said first named jaw into bunch shaping position; and means for withdrawing from said bunch shaping position said second named jawalong apath at an angle to the face of said first named jaw while said first named jaw is maintained stationary in order to loosen the bunch from the jaws.

in the direction of said last named opposed shaping device; means for withdrawing the other onposed shaping device at an angle from the bunch shaping device on the other side of said'rocking member to effect a peeling motion in order ,to

loosen the bunch from between the two last named shaping-devices; and means for alternating the opening and closing of said devices in timed relation with one another.

30; A' cigar machine in combination with a du- "plex. crimper comprising, a central member; two

sets of bunch shaping devices mounted on opposite sides'of said central member, each of said sets on said central member having an opposed set of movable shaping devices cooperating therewith to crimp cigar bunches; means for moving one set of opposed movable devices into bunch shaping position with one set of the shaping devices J mounted on said central m ember while 'maintaining the central member substantially free ,from movement; and means for withdrawing the'other' set of opposed'movable devices at an angle "from 'the other bunch shaping device mounted onsaid central member to eifect a peeling motion in order to loosen the bunch from 315A crimper for cigar bunches comprising,a
