To all whom z't may concern:

Be it known that I, HARRY S. MARSH, a citizen of the United States, residing at New York, in the borough of Brooklyn, State of New York, have invented new and useful Improvements in Cigarette Machines, of which the following is a speci,- fication.

This invention relates to an improvement in cigarette machines of the continuous rod type in which the paper forming the wrapper of the cigarette is fed from a reel in a narrow band which may pass through a s printing device for the purpose of printing thereon a legend, trade-mark or other character or it'may pass directly to a guide channel where the shredded tobacco is dropped. in a uniform layer on it, passing then under a wheel or shoe for the purpose of pressin down any loose or upstanding strands o tobacco, then to a folding `or paper curling device, being carried forward at this point by a suitably driven endless tape, where the edges ofv the paper are guided up and around the tobacco, one edge standing vertically, to the inner side of which paste is applied; then passing under a shoe which folds down the pasted side against the already folded downopposite side of the wrapper forming a pasted and closedcigarette rod. The rod then passes under a shoe which presses the -seam into closer union and evapoates by means of heat somev of the moisture in `the paste, passing then to a vdevice 1for cutting the rod into suitable lengths as completed cigarettes which are then dropped vonto a' conveyor beltV for the purpose of moving them out of the 'path of the following cigarettes.

The main lobject of my invention 1s to provide a cutting-off mechanism of' th reciprocating circular knife type capable of 7a high speed without producing the usual harmful vibrations present in the common and at the same time to provide simple means\for sealing the cigarette rod securely at the high speed maintained.

A further object of my invention is to provide means for varying the relation of the cutting point on the cigarette rod to the printed character or characters on the paper wrapper while the machine is inoperation and also to compensate for the slipping and stretching of the paper which varies with the condition of the atmosphere and the moiture content and quantity of the tobacco use v A further object of my invention is to provide means for' varying the height, while the machine is in operation, of the center -of rotation and revolution of the circular knife to compensate for the varying diameterof the yknife due to grinding its edge to a smaller diameter in sharpening.

With these and other objects in view not specifically v mentioned, the invention consists in certain constructions and combinations which will be hereinafter fully de- In the accompanying drawings which.

form a part of this s eciication and in which like characters o reference indicate the same or similar parts,

Figure 6 'is an enlarged topview of the cutting-'0H mechanism, certain parts being y shown in section. l

Figure 7 1s a sectional perspective view of the hollow screw which locks the cuttingoff knife bearing in a iixed, position after adjustment.

.Figure 8 is a sectional view on the line 8 8 of Figure 6 of the knife mounting and y cigarette guide. type of reciprocating cutting-off mechanismrv Figure 9 is a sectional view of the cutting-oit' mechanism on the line 9-9 of Figure 5.

Referring to the drawings, 1 indicates .a bed designed to support and co-ordinate the different devices utilizedv in the printing, filling, forming, sealing and cutting of the cigarette rod. :The bed is mounted on legs 1 2 and 2 and carries at the rear a bracket 3 forming bearings for a shaft 4 carrying a driving pulley 5 by means of which the machine is operated.

The bracket 3 encloses gearing for, transmitting the motion from the shaft 4 to a parallel shaft 6 .which extends from one At 7 a reel of cigarette paper of suitable` width is mounted on a spool 8 journalled on a stud 9 carried by a bracket 10.

The paper passes from the reel 7 over a.

roller 11 and around a drum 12 of the printing mechanism 13 within which any trade mark, design or characters may be printedon the paper. As no novelty is claimed in the printing device, which may be of any suitable design, it will not be described indetail.

From the printer 13 the paper lmay pass over rollers 14 and 15 to the guide channel 16 or it may pass directly from the reel 7 to the guide channel 16 if no printing is desired on the paper.

Within the length of this guide channel,

' which is formed-by walls slightly nearer together than the width of the cigarette pa.- per and beneath the edges of which walls the paper passes, the shredded or granulated tobacco is showered by any suitable automatic or-hand-fed feeding device in a gradually increasing layer as the paper traverses the channel. The funnel or-chute through which the tobacco falls is shown by dotted lines at 17 At 18 is shown a concave faced roller mounted on a shaft 19 carried in bearings 2O and 20 which may be driven by gearing 21l from a vertical shaft 22 geared in turn .to the main drive shaft 6. With certain types of tohacco this roller need not be positively driven but may be mountedfon cone The -pulley 23 carries an endless tape 25 Whichpasses over ah idler 26 and rollers 27 and 28 of a tightening device 29'through a guide 30 to a roller 31, then into and through' the rod forming and paper folding tube 32 returning to the pulley 23 at 33. i

tube, the tobacco being pressed downward against the paper at the bottom of the groove in the base 34 by the tongue 36, the paper and tobacco being carried forward through the tube 32 by the endless tape 25 which lies in tth'e bottom of the groove in the base 34.

At 39 is shown a pasting device of conventional form comprising a paste pot- 40, a paste wheel 41, which receives paste from the pot, mounted on a shaft 42 driven by gearing V43 from a vertical shaft 44 which is in turn geared to the-main shaft 6. A second paste wheel 45 whose edge extends over. the top of the cigarette rod is mounted on a vertical shaft 46 mounted in bearings' 47 and 47 having a pulley 48 at its upper end which is driven by a belt 49 from a pulley 50 on the shaft 22.

The paste wheel 45 which is in contact with the concave face of the paste wheel 41 j receives paste therefrom and applies it to the inner side of the upstanding edge of the paper as it passes this wheel at 51. The folder shoe 52 having a groovedunder face then guides andpresses the pasted edge of the paper down against the previously folded opposite edge, thus closing the paper tube surrounding the tobacco.

At 53, Figs. ,1, 2, 3, and 4 is shown a sealing device comprising a channeled shoe 54 mounted at the end of an arm 55 pivoted on a shaft 56 and' having bearings 57 and 58 for a shaft 59.. The free end Aofthe arm 55 is supported by an adjustable screw 60 bearing against a'lug on the bracket 35.

Within the channeled shoe 54 is mounted a second shoe 61 pivoted on a stud 62 in the arm 55 having a4 curved upper ,surface which fits against the periphery of a wheel 63 secured on the shaft 59. Pivoted in its free end, the shoe 61 has a vertical rod 64 which passes through a lug 65 on the arm 55 and has an adjustable nut 66 on its upper threaded end. Between the lug 65 and the nut 66 and surrounding the rod 64 is disposed a compression spring 67 whose pressure through the rod 64- draws the shoe 61 up-y ward into contact with the wheel 63.

The shaft 59 has at its'rear end a bevel gear 68.which engages a bevel gear 69 on the shaft 56 mounted in bearings 71, 72. The shaft 56 has at one end a pulley 73 driven by a belt 74 from a pulley 7 5 mounted' on the side of the main drive-pulley 5.

vand 2 and in greater detail in Figs. 5, 6, 7,

8 and 9 comprises a wide faced helical gear 76, in Figs. and 9, slidably mounted on the main shaft 6 and having keys 77, 78 engaging longitudinal keyways in the shaft. The gear 76 is embraced by a yoke 79 the arms of which are forked and guided byV the shaft 6. The hub of the yoke 79 is mounted on a threaded shaft 80 parallel to the shaft 6 and having bearings in the bed 1 and bracket 81 and having a collar 82 and hand wheel 83 which resist the end thrust of the shaft 80. By means of the hand wheel 83 and the threaded shaft 80 the yoke 79 and gear 76 maybe moved longitudinally of the shaft 6 while the mechanism is in mo` tion.

Adjacent to the shaft 6 Figs. 5 and 9 is mounted a parallel shaft 84 having bearings in the bed 1 and bracket 81: and carrying a helical gear 85 which engages the gear 76, and also carrying at one end a bevel gear 86. The shaft-84 has ball thrust bearings 87, 88 and a collar 89 to resist the end thrust due to the action of the helical gears.

rllhe bevel gear 86 engages a bevel gear 90 on a shaft 91 mounted in bearings in bracket 81, bed 1 at 92 and bracket 93. Mounted on the shaft 91 is an eccentric 94 embraced by one end of a connecting rod 95 which connects at its opposite end by means of a pin 96 with a sliding carriage 97 mounted by means of tongues 98, 99 secured thereto, on guiding ways 100, 101 in turn mounted on the bed 1, parallel withv and adjacent to the center line of the cigarette rod as it passes through the machine.

Mounted also on Jthe shaft 91 is another eccentric 102 whose center of eccentricity `is oppositeI to, or 180 degrees from that of the eccentric 94. The eccentric `102 is similarly embraced by one end of aconnectng rod 103 which is connected at its opposite end by means of a pin 104 to a sliding weight or counter balance 105 slidably mounted on guiding tongues 106, 107 secured to the bed 1, directly underneath and parallel to the ways 100, 101.

The wei ht 105 has an upwardly extending lug 108 which enters a recess formed in the under surface of the carriage 97. The carriage 97 has at its ends downwardly projecting lugs 109, l11() to which is secured a rod 111 which passes through a hole in the lug 108 of the weight 105. urrounding the rod 1117 between the lug 108 of the weight and the lugs 109, of the carriage are mounted opposed compression springs 112, 113. The purpose of these springs is to cushion thel blows land aid the reversals of motion of the carriage 97 and weight 105 as they are reciprocated at high speed by the rotation of the eccentrics 94 and 102.V

Projecting upwardly from and integral with the carriage 97 is a split bearing 114 having a cap 115 within which is secured a sleeve or bushing 116 which projects at its ends a short distance beyond the ends of the bearing 114 and cap 115.

On the projecting ends of the bushing 116 are pivoted the hubs 117, 118 of a knife carrying frame 119 which is capable of being rocked on its pivots for the purpose of adjusting the height of its knife carrying en Between the rearwardly extending ends of the frame 119 mounted in hubs 120, 121 is a rod 122 which is embraced by a forked projection of a vertical slide 123 mounted in a bracket 124 secured to the bed 1. The slide 123 has at its rear side a projecting bearing 125 for a vertically mounted adjusting screw 126 which has a shoulder 127 below and a handwheel 128 above the bearing 125.

The screw 126 is threaded. into a tapped hole in a projection 129 of the bracket 124. By rotating the handwheel 128 and screw 126 the slide 123 may be raised or lowered, at the same time (through the forked projection 123 and rod 122)l rocking the knife carrying frame 119 while the carriage 97 and frame 119 are reciprocating.y

In one arm of the frame 119 is formed a curved slot 130 through which passes a hollow screw 131 in the flanged head of which -is formed a narrow slotted opening 132'. The screw 131 is threaded into a projecting flug ,133' of the bearing 114 and against which the arm of the frame 119 may be clamped.

Passing through the slotted opening 132 and the hollow interior of the screw 131 is the flattened end 134 of a shaft 135 which is mounted in alignment with the screw 131 in a bearing 136 of the bracket 93 and is held against longitudinal motion by4 a collar 137 and handwheel 138 at opposite ends of the bearing 136.

By means of the shaft the screw 131 may be loosened releasing the frame 119 to permit its adjustment and again clamped in position while the parts are reciprocating.

The frame '119 has bearings 139, 140 formedin the portion opposite to the adjusting and clamping devices, adapted to rotatably support a conical sleeve 141. The sleeve 141 carries in an eccentric bearing 142 a shaft 143 which in turn carries collars 144, 145between which is clamped a circular knife 146 by means of a nut 147. Formed integrally with the shaft 143 is one member of a universal `joint 148 of familiar construction which is connected by' a rod 149 with a similar universal joint 150 one memvis mounted a grooved pulley 153 which is rotated'by a belt 154 from' a pulley 155 mounted on the previously described shaft 56.

The conical sleeve 141 has at its large end weights 156 of relatively heavier metal placedin a position to counterbalance the weight of the. eccentrically mounted shaft 143, collars 144, 145 and knife 146 as well as any otherwise unbalanced weight.

The projecting small end of the conical sleeve 141 has a spur gear 157 secured there,- on which engages with another spur gear 158 mounted on a shaft 159 which has bearings in the bushing 116 and a hub of the bracket 93. 0n the end of the shaft 159 is lsecured a bevel gear 160 which engages with another bevel gear 161 secured on the upper end of the vertical shaft 91.

The gear 158 has a hub 158a'in which is formed an annular groove which is embraced by a split yoke 162 secured to a flange` formed on the hub 117 of the frame 119 for the purpose of carrying the gear with the frame 119 and its supporting carriage 97 in their reciprocating movements.

The gear 158 has on its other side a long hub 163 having longitudinal slots 164 in which are located rollers 165 mounted on a pin 166\which` passes through and is secured in the shaft 159.

rlhus while the shaft 159 is held against longitudinal motion by the gear 160 and a collar 167, its rotary motion is transmitted to the gear 158 through the pin 166 and rollers 165 While lthe gear 158 is reciprocating on the shaft.

rlhe'hub 163 of the gear 158 is covered by a guard sleeve1`68 and a cap 169 which protect the slots 164 from dust and serve to -retain the rollers 165 in place.

The carriage 97 has a projecting arm 170 which carries in line with the cigarette rod, a guide 171 and a lshearing die 172 against which the circular knife cuts as it revolves about the center of the conical sleeve 141 and rotates on its own shaft 143.

The carriage 97 also has another projecting arm 173 which carries a guide tube 174 which enters a stationary guide 175 secured to the bed 1 Fig. 8.

Below and adjacent to the guide 175 1s 'an ordinary conveyor belt 176 mountedon suitably driven pulleysy (driving means not shown) carried by brackets secured to the end of the bed 1.

As the closed cigarette rod leaves the` folder shoe 52 resting on the tape 25 it passes under the sealing shoe 54 which presses the seam into close union. Bymeans of the heat generated by the friction of the Wheel 63 against the shoe 61, which 'is made of heat conducting material, the heat belng transmitted to the shoe 54 which is also made of heat conducting material, a portion of the moisture in the pasteis evaporated,

thus securely sealing the paper wrapper of the cigarette rod.

As the cigarette rod now has considerable rigidity it passes unsupported to and through the guide 171and cutting die 172 ofthe At a certain portion of the revolution of the eccentric 94 the motion of the knife is so timed as to travel in its reciprocating motion at approximately the speed of and in the same direction as the cigarette rod.

.The revolving and rotating knife is so timed that during the short time when it is travelling With the cigarette rod its vedge will pass downward across the opening in the shearing die 172 and rise again clear of the path of the cigarette rod before the relativespeeds of the knife and rod have altered materially, producing a substantially square cut across the cigarette rod Separating the desired length to form a finished cigarette.

Through the driving mechanism described imparting a reciprocating motion to the Weight which motion is opposed to that of the carriage 97, due to the opposed relation of the eccentrics 94 and 102.,

vThe weight ofthe weight 105 is intended to be equal to that of the carriage 97 and mechanism carried by it. As the Weights of the two reciprocating bodies are ,equal and the motions are parallel and opposed to each other the vibrations produced by the reciprocating bodies are substantially equalized and the bed of the machine is not subjected to the vibrations common in the ordinary type of reciprocating rotary knife cutof mechanisms.

The springs 112,- 113, which are alternately compressed as the carriage 97 and weight 105 move in opposite directions, cushion the blows due to the stopping of the motions and aid the reversals of motion of the two bodies equally. Q

Should it be desired topchan'ge the relation of the cut to the printed design on the clgarette paper it will be necessary to alter the time of revolving and reciprocating theknife relative to the rod carrying tape 25.

.'lhis is accomplished by, turning the hand h' stoodthat various .structural changes may l the axis, a counterbalance on said member on relation on the^ pitch circleof the gears in direct proportion to the tangent of the angle of the teeth of the helical, gears.

While the invention has beenl shown and described incombination with a cigarette machine, it will be understood that it is not `limited to such an application and may be used in conjunction with any apparatus in which moving rod-like strutures should be cut into suitable lengths without interruptmg their movement. It will also be Aunderbe made without departing from the principle of the invention as defined in the appended claims.
