General 'idea of themackim, including the locatio'nond functions of its principal partsr Referring to the drawings, 1 represents the frame of the machine in which are journaled the main shaft 2, having driving pulley 3,

l and three

parallel shafts

4, 5 and 6 which are driven by suitable connections to the main shaft. The strip -7, from which the inner package wrappers are cut, is fed over themolds or pockets from a spool ii located at the right hand end of the machine. At one side of and at the top of the machine. are located the hopper 9 and the devices for separating and. feeding the cigarettes to the molds, also, the card box or holder and card feeding devices; and, on a lower plane on the

respective shafts

4, 5 and 6, are three wheels or

drums

11, 12 and 13, each provided with molds or pocketsli in their peripheries into which the wrappers, the cigarettes and cards which form the packages are forced. The three mold wheels are arranged to rotate intermittently with their peripheries near each other, and when they are at rest a mold of each wheel will registei' with a mold in each of the other wheels, and means are provided to shift the packages from wheel to wheel toiacilitate their formation and completion. At the right hand end of the machine are also located a box for holding a pile of .label-wrap pers and devices for applying paste thereto and feeding them over the molds of wheel 13. The inner wrappers, the desired number of cigarettes and cards are first forced irito themolds of the larger wheel 11, in which the packages are only. partially formed arid from which they are forced'into the molds of wheel 12, where the ends of the wrappers are folded, and; thence into-t1".

located at the right hand end of the machine and is fed to the properfposition over the top mold of wheel 11 by passing between the feeding rollers 18 and 19 when the desired length of strip to form the width of a. wrapper is severed by a cutting blade 205 The spool 8 is ournaledin standards 21. and the strip 7 passes over an idler 22 and under unwinding roller 23 and between feeding rollers 18 and 19. I To insure a uniform eed of the rpllers it is desirable that the unwinding of the strip from the spool be done'by other devices-than the rota tion of the feed rollers and when the rollers are at rest and are holding the forward end of the strip between them. To accomplish this the roller 23 is arranged above the strip and to reciprocate up and down and unwind at each downward movement a length of strip for the' Width of a wrapper. in the direction to feed the strip forward, and for this purpose. as shown in Figs. 2 and 3. a ratchet wheel 25. secured to the shaft of roller 18, is rotated by a pawl 26 fast to a geared pinion 27 loose on the shaft. and this pinion is rotated back and forth by a meshing geared 'sector 28, pivoted at 29 and oscillated by its connection with lever 30 secured at its lower end to rock shaft- 31 and operated to give the required oscillation to sector 28 to rotate rol er 18 by its engagement through roller 33 with cam groove in the periphery of wheel 32 on shaft 2. Roller 19 is preferably driven through gear connections with rol er 18 and these rollers are constructed apd arranged in the usual way of feed rollers. The desired reciprocation of unwinding roller 23 is given by its connection with rock lever 30 through link i a 34 and bell crank lever 10 having stationary pivot at 35.

By the devices just described the free end of the strip is fed over the top mold of wheel 11 as the wheel steps. so that its forward edge projects sufficiently beyond the mold to form laps or folds at one end of the package while one contiguous edge projects beyond the rear side wall of the mold to form a longitudinal edge fold nearly equal to the edge of the package and its opposite edge projects beyond the forward wall of the mold sufficiently to wrap around two edges and one side of the package as seen by reference to Fig. 28. ahd when in this position a blade 20 descends upon an opposing blade or anvil 37 and severs the strip far enough from the mold for the folds on the other end of the package.

The strip 7 for the innei wrappers is preferably compound, made up of a thin strip of tin foil, or other nonporous material, and paperpasted, or otherwise sccured, together, aithoug h-a simple strip either of tin foil or paper may be used. [f a strip of tin foil oisimilar material, or a compound strip is used, it is desirable to have a cutter of peculiar construction to sever it cleanly and leave even edges. For this reason both the upper and lower cutting edges are formed with saw teeth 38 which mesh as they come together and make 'a clean even cut. "The upper blade 20 is removably and adjustably fixed in the forward edge of frame 39 whichis pivoted at 40 and is operated by its connection The feed rollers rotate only through rod 41 to lever 42 which is rocked by its connection'with cam groove in wheel 44 on main shaft through friction roller 45. g

Cigarette and card separating and feeding mechdm'sms. The cigarettes to be made into packages are placed in a hopper 9, Figs. 1, 3. 4 and 9,. whose width is slightly greater than the length of the cigarettes, either by hand or otherwise. The hopper is provided with a bottom 47 which supports the cigarettes and is arranged in a single plane as distinguished from hopper bottoms arranged in different planes and slanting in several differ ent directions toward the hopper exit. The single hopper bottom 47 is inclined, preferably at an angle of about 30 degrees, towards the exit which is only slightly deeper than the diameter of a cigarette. 'This single inclined hopper bottom is considered an important feature of the machine as itcauses the cigarettes to constantly move by gravity towards the exitand does away with thevarious devices heretofore employed to move them, and together with the vibrator presents the cigarettes in asingle row or layer tothe mouth of the race 48 and w the swinging platforms at the bottom of the race. To prevent the cigarettes from clogging at the mouth of the race 48, which forms the exit of the hopper, a vibrator or agitator 49, Figs. 3 and 4, fixed to a shaft 50 passing through the hopper, which shaft is rocked by the contact of its downwardly projecting arm 51 with pins 52 on wheel 53 and its release therefrom, operates to throw or push the upper layers of cigarettes backward from the mouth of the race so that those. of the lower layer are free to enter it. Buffers 15 may be'attached to the outer and inner wall of the hopper to receive the strokes of the vibrator and arm 51. The race 48 extends from within the hopper downward over the top vmold of wheel 11 and is sufficiently steep to press the cigarettes close together at its lower end over the mold wheel where it is level and is provided with an end wall or abutment to stop the cigarettes. The bottom of the race over the mold wheel is divided into two 7 parts or platforms 54 which are'hinged to the adjacent parts so as to swing downward and outward under proper pressure to uncover the mold and permit the cigarettes whose opposite ends rest on theseswinging platforms to be forced into the mold, the platforms being controlled by springs 55. or other means. to re turii them to their normal position as soon as the pressure is removed.

The lower end of the race may be provided with an adjustable stop 24 to diminish or increase the length of F the platforms 54 to compensate for slight variations in the size of the cigarettes. r I

In front of the hopper and over the race is located a straightener, Fig. 3, which consists of a light transverse spindle 57 provided with hooks or projections 58 resting on the cigarettes as they pass beneath them down the race. These projections touch the cigarettes lightly near their ends and bring them into a position at right angles to the line of the' race, andthe straightener is operated solely by the impact of the cigarettes against the projections 58. Thetop of the race is provided with overhanging flanges which prevent the. cigarettes from being forced out and the race is only deep enough for a single layer of cigarettes and in its normal condition it is filled throughout its length.

When a wrapper is in proper position'over the top inold 'of wheel 11 and the swinging platforms above the wrapper and the mold are filled'with a layer of cigarettes; both the wrapper and cigarettes are forced simultaneously into the mold by the operation of a vertically reciprocating plunger 59, arranged to make as many downward movements during each stop of the mold wheel as there are layers 'ofcigarettes to be forced into the mold. The plunger 59 (see Figs. .1, 3 and 4) is pref erably cushioned by spring 46 around its stem and is secured to pivoted lever 60 which is rocked by its connection with cam groove in the face of wheel 53 rotated by a chain or belt 61 passing over wheel 62 on main into each package. For'this purpose an open top box 63 adapted to contain a pile of cards, having a cross area i slightly greater than the surface of a card, is fixed at one side of the top mold of wheel 11, andthe bottom card of the pile is pushed by a reciprocating pusher 64 through a narrow opening in the front-of the box over a layer of cigarettes on platforms 54, arid thenis forced by the plunger 59 into the mbld with the cigarettes. A guide 65 is arrangedupon the farther side of the race to direct the forward end of the card under the overhanging flange of the race. The pusher is attached to a slide -66 moving in suitable ways. which is reciprocated by its connection with lever 67 fast to shaft 68 which is rocked by the engagement of arm 76 with cam groove in the periphery of wheel 69 on main shaft 2, (Figs. 1, 2 and 3). A light weight may be placed ontop of the pile of cards to bring the bottom card in position'to meet the pusher 64.

Mold 'wheels, their connectfrms and moi ements; construclion of molds, devices for shifting packages from wheel to wheel and devices for folding the ends of the wrappers.The mold wheels 11. 12 and 13, carrying their respective molds 14, are constructed, arranged and rotated so that when the wheels are statihnary or atrest the top mold of wheel 11 will register with plunger 59, and two molds of each wheel will register with molds in the other two wheels as shown in Figs. 1, 2,

" 3, 4, 5,15 and 22. Wheel 11 is intermittently rotated and dogged or held stationary through the engagement with star wheel 56 fast to shaft 4 of a roller 71 on crank 70 fixed to inain shaft 2 near its end, the roller 71 taking into the notches 72, while the dogging roller 73 on .bell crank lever 74 is arranged to be removed from the notches 72, as soon as the roller 71 enters them, by the action of the latter roller on the curved arm 75 of the bell crank leyer 74; and is thrown into the next notch as soon as roller 71 has left its notch, by the action of spring 77, as shown' in Fig. 5. The. mold'wheels 12 and 13 are rotated by connecting gear ,wheels 78 on shaft 4 and 79 on shaft 6, and by gear wheel 80 on

shaft

6 and 81 on shaft 5, as seen in Figs. 1, 2 and 5. The molds 14 of

wheels

11, 12 and 13 are open at their opposite ends, and each isfiprovided with a mov able bottom 82, Fig. 14, having a stem 83 projecting therefrom towards the center f 'thc wheels and devices for holding the bottom stationary in whatever positioninthe mold itmay be forced and left. -Co nveniently the stem'83 may pass through a hole 84 in a stationary enlargement 85 and be forced into frictional holding contact by spring 86, as'seen in Fig. 14; or- 70 anyother suitable holding device may be used. By

this arrangement whenever a completed'package is exv N pelled from wheel 11, by moving the bottom of the moldto its top or mouth, the bottom will remain inthat position to receive'the wrapper-and the first layer 75 of cigarettes and support them as theyare forced downward into the mold by the'plunger 59, and as the plungeronly moves downward. to the top of the mold, the bottom will continue its support until it is forced down step by step by the forcing contact of a subsequent 8() layer or layers hf cigarettes. So, whenever the packages are shifted from wheel to whe el, Figs. 15 and 22, the bottoms of the discharging molds are forced outward and those 'of the receiving molds irQvard, and the bottoms which have been forced outward remain in 85 that position until they are forced inward by the'cn-, n trance of the next package and are thus always in place to support the packages and prevent the wrappers from being displaced and wrinkled.

The packages are shifted from wheel to wheel simultaneously, that is, a package is shifted from wheel 11- to wheel 12, another from wheel 12 to 13 and another from wheel 13 to'wheel 11, and still another is discharged from wheel 11 into the expelling trough 87,. all at the same time and by devices actuated By a siIi- 95, gle earn, as follows, Figs. 1, 2, 3 and 4? Bell crank lever 88 fast on shaft 89 is rocked by'its connection through toggle joint 90 and bell-crank lever 91 with cam groove in face of wheel 92 on main shaft 2. To lever 88, Fig. 4, is pivoted a rod 93 which is connected by link 94 'to rock shaft 95 on which are fixed two

arms

96 and 97, the end of arm 96 being arranged to take against the end of the stems.83 of the bottoms of molds of wheel 11 to push the movable bottoms outward and .shiftthe packages to the molds of wheel 12, The end of arm 97 l is pivoted to another arm 98 yoked over shaft 5 'and provided with a projection to take against the stems 83 of the bottoms of molds of wheel 12 and force thcin outward to shift the packages into the registering 4 molds of wheel 13, and to the upprend of lever 88- is pivoted a rod 99 whose opposite end is yoked'over shaft 6 of wheel 13 and is provided withmeans to take against the stems of the bottoms of the molds of wheel 13 and shift the packages therefrom into the molds of wheel 11, while the upper end of lever 88 strikes ,against the ends of the stems of the bottoms of the molds of wheel ll'and discharges the completed packages into trough 87. The rocking of lever 88 towards the left as seen in Fig. 4 gives the requisite movements to produce the results just described.

The folding of the wrappers around the cigarettes is effected by the following means, Figs. 15 to 21': When a wrapper is disposed over the top mold of wheel 11 as previously described, the forcingof the cigarettes into the mold causes the wrapper to be folded over the two long edges and one side of the package by the contact of the wrapper with the side walls of the mold, and as the wheel rotates the forward unfolded part of wrapper is brought into cdfitact with the rear edge of the curved retaining folder 100, Fig. 15, and is folded'over upon the top layer of cigarettes in a mold, the extreme edge of the wrapper restingon the periphery of the mold wheel, and when a package-is shifted from a mold of wheel '11 to a mold of wheel 12, this extreme edge of the wrapper is folded-over upon its opposite edge by contact with the side wall; of the mold.

The ends of the wrapper which project beyond the open ends of the mold are folded during, the rotation of wheel 12, Figs.' 15 to 21, by the.action of oscillating fingers 101 arid stationary folders fixed in or made a part of the curved holder or case 102, secured to the frame to fit over the periphery of wheel 12, the end folds or laps thus formed being designated as rear edge folds 103, forward edge folds, 104', bottom end folds 105 and top end folds 106, as seenin Fig. 26. The 0scil lat ing fingers 101 form the rear edge folds 103 on both ends of the package, and for this purpose they are arranged to operate oneach sideof the wheel 12 simultaneously by attaching them to arms 107 which are connected together and arranged to rock on shaft 5,-and they are oscillated through the connection of arm 109 ,fixed to one of arms 107 with link 110 attached to arm 182 which engages with cam groove in face of wheel 111 on main shaft 2, the arm 182 being adjustably'fixed to arms 181 carrying another pair of oscillating folders hereinafter referred to, asshown in Figs. 1, 4 and 6, and the cam groove being shaped .to move the fingers 107 forward more rapidly than-wheel 12 moves so as to form' folds 103 before that part of the package'enters the stationary holder or case 102.

The ho'lder 102 and its folders are preferably of a single piece of metal wrought into the desired shape, and

the holder 102, the folds being formed by the contact of the wrappers with the edges 113 of the folders which are preferably slightly rounded, and the

folds

104 and 103 are held in place by the thin extended fingers 114 until they are caught and held by the upturned bottom folds 105'which are formedby the upwardly inclined folders 115, whose rear ends overlap the retaining fin gers 114 and whose forward ends are cut away to form similar retaining fingers 116 to hold the upturned bottom folds in place until the top folds .106 are tnmed down upon them by the overlapping rear ends of'down wardly inclined folders 117 which operate to form folds 106. When the wrapper ends are thus folded the holder is narrowed to the length of the completed package,-or

- a retaining section 118 is added, and in either case the side walls hold the folds in place until the point to shift the packages to molds of wheel 13 is reached. The oscillating fingers 101 swing close to the entrance of the holder 102 and hold theio1ds103 in position, Fig. 16,

so that they readily pass the edges offolders 112 without wrinkling. As the packages are passing the folders 112, the outstanding parts of the wrappers which form the folds-.105 and106 move along the'bottom and top edges edges being 113,

ses,1a1

with the r'espectivefolders 115 and117 which form these outstanding parts into

folds

105 and 106, the

folding

120 and 121 respectively. (See Figs. 15 m 23 Devices for applying paste to outside or label wrappers and for feeding such wrappers overthe molds .-When the packages have passed by the folding devices of wheel 12 and through the curved retaining section 118 and are brought to register. with molds of wheel 13 but before they are shiftedthereto, label wrappers are fed over the top of the'receiving molds of wheel 13 to occupy substantially the same position thereto as the wrappers occupiedto the top moldsof. wheel 11 as heretofore described. The label wrappers cut to the proper size are placed in a pile upon a vertically movablebottom or platform 122, Fig. 10, in an open ,topped box 123, the platform beingconstantly pressed upward by a spring 124 to force the upper wrapper against a sharp point 155 located at the rear side of the pile.

The pasting devices, Figs. 10 to 15, are located at one end of the box 123 and consist of a paste reservoir 126, a delivery roll 127, paste taker and applying

fingers

128 and 129, and devices for moving the fingers to and from the paste roll and the top wrapper-of the pile. The paste fingers operate to apply a line of paste 130 with a central break or opening 130 to one end of the wrappers to seal the oyerlapped longitudinal seam v and two shorter lines 131 on the sides of the wrapper to seal the end folds of the package in place is shown in Fig. 14. The paste fingers are carried on arm 132 which is pivoted to top of rock lever 133 fastrat its lower 'end to shaft 125 which is rocked by lever 91' connected to cam groove in face ofwheel 92 to give the desired backward and forward movement to arm 132.

The fingers 129 are attached directly to arm 132 but,

in order that both sets of fingers, may be brought in contact with the upper part of the paste roll at the same-time, the finger 128 is attached to arm 132 through rod 134 which-passes. closely through guide holes in lugs 135 on the fixed arm 132, and as this arm is moved backward the end of rod 134 abuts against the stationary stop 136 and contracts spring 1371 The backward movement of the arm 132 is continued until the fingers 129 are brought'into line with finger 128 when the fingers are over the axis of the paste roll and are pressed upon it to take paste. As the paste roll' is located below the top of the wrapper pile the arm 132 is moved downward by the contact of roller 138 with an inclined guide 139, the roller being held to the incline by spring 140 fixed at one end while its other end is fastened to arm 141 which forms with arm 132 a bell crankf lever. When the fingers have taken paste from the V roll and the arm 132 moves forward, the rod 134 remains in contact withthestop 136 until the expansionforce of spring 137 is expended, at which time the fingers have resumed their normal relative position and then they movh together over the upper wrapper of the pile and are brought down into applying contact therewith by the abutting of the lower end of arm 141 against adjustable stop 142 just before the forward movement of arm 132 ceases. To p event the contact of the fin' gers with the wrapper before they reach their applying position, spring controlled pins l43'with rounded ends project slightly below the fingers and by riding over the of folders 112, Fig. 19, until they are brought in contact l" wrapper keep the paste fingers out of contact therewith until they' are forced down to apply paste, and when they are lifted upfrom the wrapper the pins 143 act as strippers. The lingers-129 are preferabl'y of yielding material, as spongy rubber which will conform to the surface of the paste wheel, andfinger 128 is preferably cushioned by a spring 144, this tinger'being formed with a central notch 145 to cause-a break or interruption 130 inthe line of paste, as seen in Fig. 1.4. The paste wheel may be rotated by the engagement with ratchet 146 fast on wheel shaft of pawl 147 pivoted to arm 148 arranged to rock on wheel shaft at oneend .while to its other end is pivoted arm 149 attached to and operated by rock lever 133, see Figs. 3 and 12.

The label wrappers are fed individually from the top of the pile in box 123 over the molds of wheel 3 by the operation of the pusher 150 and the

feed rollers

151 and 152. The pusher is preferably of spongy rubber, or similar material, secured to arm 153'on pin 153.

and is operated through connecting arm'154 on rock shaft 31 which is rocked as heretofore described, to give the pusher a downward and forward movement to feed the top label into the bite of the feed rollers and then an upward and backward or return movement. -11- necdle, or other sharp point, 155, carried on the end of arm 156 fast to rock shaft 156 is .thrust into the labels at the rear of the pile by the contact of pin 157 or rock arm 154 with arm 158 faston shaft 156 and the point 155 is raised up or partly out of the labels by the action of spring 159, in order to clear it of accumulated fibers and enable it to pierce the same number of labels at each stroke or downward thrust, the ofiice of this point being to hold the lower sheets of the pile in place while the top sheet is fed forward by which movement a short slit is torn or cut in its rear edge. It is not essen-' tial to the effective operation of this device that the point be positively raised, since its downward thrust will be resisted by the spring controlled platform 122 and will cause the pile of sheets to vibrat'e vertically .over the point and will clear it of any clinging fibers. The forward movement of the pusher 150 is sufficient to feed the forward end of the tbp sheet of the pile over the bridge 160 and into the bite of the

rollers

151 and 152, which are mounted upon their respective shafts and arranged in the usual manner of such rollers, the

lower roller, being rotated by the mesh of a beveled gear 161 on its shaft with a. corresponding gear 162 on shaft 163 which is driven by connecting chain or belt 164 passing over wheels 165 on shaft 163 and whee 166 on shaft 2, while the upper roller is rotated by meshing gears on the respective roller shafts. 'The feed rollers are shaped to take hold of the labels only near their ends, and one upper roller is arranged to bear upon the label between the lines of

paste

130 and 131 soas not to disturb them an adjustable label regulator 188 is arranged to deliver light strokes. upon a label when out of proper position on platform 167, the stem-of the regulator being pivoted at its lower end, and is rocked back and forth to deliver its strokes by c ontact of end of rod 99, or other projection on shaft 6, and by spring 189, see 4, 11, 12 and 22. A label is fed over a mold of wheel 13 just before a package is shifted from wheel 12 to the label covered mold of wheel 13, the part of the label carrying the paste projecting beyond the mold in the direction of the rotation of the wheel as shown in Fig. 22. l

Devices for folding the label wrappers around the-packages and expelling the completed packages from them c'hine..-\s the packages are shifted from wheel 12 into the molds of wheel 13, the labels will be foldedaround Y the two edges and one side of the-packages, and as the wheel advances the projecting and pasted ends of the labels will be folded back and held in place by the stationary retaining platform folder 167. To prevent wiping the paste'frofn this part of the labels by their contact with the movable; bottoms of the molds of .wheel 12 from which the packages were shifted, these 1 bottoms are provided with central projections or ribs 168 which pass throughthe-'breaks or openings .130 in the lines ofpaste and hold them out of contact with such bottoms while the forward half of the label is turned backward. Ribs 169 are also preferably formed on wheel 13'between the molds to keep the lines of paste intact while the packages are inwheel 13 as shown in Figs; 2, 6 and 22. As'thepackages are forced from the molds of wheel 13 into the registering molds of wheel 11, the extreme pasted edge of the label through its contact with-the side wall of the receiving mold is turned back upon the edge ofthe package to overlap the opposite edge of the label and is pressed vinto sealing contact therewith, as shown in Fig. 22. 7 While the end side folds of the label orouter wrapper I are being made; it is important to press and hol d the end folds of the" inner wrapper against the ends of the t package, since they are liable to spring away either during or before this operation. For this purpose a pair of oscillating pressing and holding fingers, called fold holders, are arranged to operatef at the ends of the receiving mold of wheel 11. Eac'hinember of the pair consists of a plate or holder 170 secured to arm 171 and of a plate or holder 172 elastically and slidingly secured to holder 170 to have a conjoint and independent movement therewith by means of a spring 173 secured -to pins 174 fixed in the respective holders, the

pin fixed to holder 170 passing through a slot 175 in holder 172, the said pin and slot being so arranged rela- 10.5 tively to the working ends of the holders that when the spring 173 pulls holder 172 forward against the. head of the slot its working end will be in-advance of the end of holder 170, which may be regarded as their normal positions, as shown inf Fig. 25. When both holders are pressed against the "end of-the package, as I shown in Fig. 2 1', holder 170 will be moved away first and holder 172 will bem oved as soon as the pin strikes the head of the slot. Figs. 24 and '25 show the positionof the fold holders relatively to the edge or thickness of the package and Fig. 23 shows their position relatively to the width'of the packag and' tothe edge

folders

176 and 177 by which edge folds of the label wrapper are brought down upon and overlap the top' and bottom folds of the inner wrapper and hold'them in place until the last end fold is made and sealed to complete the package. The arms 171 are pivoted at their lower ends and are connected together by toggle joint 178 and are moved to andrfrom each other by engagement of roller 179 with cam 180 on shaft 2 to give the required movement to the fold holders.

The oscillating fingers or folders 176 which form foldsof the label wrapper at one edge but on both ends of the package aretcan'ied on the endsof arms 181 and are of substantially the same construction and opera- 182 which as before described is rocked by its engagement with cam groove in face of wheel 111 on main Shilft. L y l t The stationary edge folders 177- and the top and bottom end folders 184 and .18-5'are attached to and form a part of the curved holder 186 fixed to conform to the periphery of the wheel 11, and are substantially of the same construction and operate to form and hold their respective folds in the same way as the folders 112," 115 and 117 of holder 102 which formv the corresponding folds of the inner wrapper when the packages are in .the molds of wheel 12. After folder 185'has formed the last fold thewalls of holder 186 are narrowed ti) conform to the length of the package and hold the end folds in place or an additional section 187 s used for this purpose, till the packages are discharged from the molds of wheel 11 into trough 87 through which they are moved by the pressure of the subsequent packages until they are expelled from the machine, the trough being sufficiently narrow so that its side walls will cause the end folds of the packages, to be forced inwardly and held in sealing contact throughout the length of the trough as well as throughout section 187 after the final end fold is made.

In view of the statements of the operation of the several devices and groups of devices or mechanisms hereinbefore made in connection with the descriptions of their construction and arrangement with each {other and other parts, it is not considered necessary tofurther describe the operation of the machine.

It. is of course, understood that the several operative parts are so timed that they will perform their work in proper succession and during such periods as not to interfere with each other, and that the cams and other actuating parts are so shaped and arranged as to give to the devices operated thereby the movements requisite to do the work herein ascribed to them.

It is not intended to limit the present invention to a machine of the exact orspecia'l construction shown in the drawings and hereinbefore described by reference theretovor to a machine embodying all the devices and combinations, or equivalents therefor as shown and describedfinasmuch as it .is evident that a machine may in some particulars be of radically different. construction, while in other particulars it contains not only the principle of the invention, but the devices and combinations, or some of them, as herein fully described'and claimed. r h
