0 represents a transverse shaft mounted in upright bearings c c on table A and forming the main or principal actuating-shaft of the machine. In the several views of the drawings I have shown this main shaft provided with a handled crank O, by which it may be operated by hand; but in practice I prefer and intend using a pulley instead, which pulley is connected by belt with any suitable revolving power-transmitting shaft.

a is a crank-arm secured to driving-shaft C and pivotally connecting, by means of a vertical pitman or rod a with the outer end of a rocker-arm a which latter is secured at its opposite end to the rock-shaft b. The said pitman passes down ward from said crank-arm a through an opening a in the table, as clearly shown in Fig. 5, and imparts intermittent motion to the wheel or cylinder B through the medium of a spring-controlled driving pallet or pawl b on the inner face of the rocker-arm a which pallet engages teeth 12 on the periphery of a disk b constructed on the outer end of the hub 11 of the main part or body of the said wheel or cylinder.

0 represents a vertical arm pivoted at.- its lower end on the longitudinal base-plate or discharge-table A and having at its upper end an imvardly-projecting stud or stop-pin 0 which engages radial notches c in said disk-b and thereby firmly and steadily holds the wheel in position when the candyis feeding or the rock-shaft is moved backward in the upstrokes of the pitman.

c is an actuatingspiral spring strained between the vertical arm c and the rear end of the discharge-plate A to hold said arm and its stop-pin c in working contact with the notched disk or ratchet-wheel b, as shown in Fig. 3.

D represents a horizontal carrier or feeding metal-faced stationary circular bottom plate or track (1 located intermediate it and the face of table A, said springs d in the candyreceiving pockets supporting said candy free from undue friction upon said plate. An opening d (see Fig. 2) is made in circular plate (1 in line with the path of said ram D through which the candy is fed to the wrapper immediately beneath.

d is a projection or lip on the plate 01*, under which the wrapping-strip of paper is fed beneath said ram, as hereinafter described.

D represents a longitudinal slotted bar adjacent one edge of the feed-disk and reciprocated along the upper face of table A by means of vertical crank-arm D which latter is secured at its lower end to the rock-shaft b and connected by a slotted rod or link D (at its upper end) with the slide-bar D as clearly shown in Fig. 1. Slide-bar I) is provided with a pallet or click (1, which engages peripheral notches d in the feed-disk, and thereby imparts. intermittent rotary motion to said disk to feed the candy up to said ram D D represents a hollow upright guide or race way, in which the ram or plunger D reciprocates. This guideway extends upwardly from a base-plate d, which spans a portion of the feed-disk and is suitably attached to the table A, with sufficient space between it and the upper face of said table to permit of both the presence and free rotation of said feeddisk. The upper end of ram D is pivotally connected with an open concaved projection at one end of a rocker-arm or beam E, which latter pivots at or about its center upon an upright frame or support E on the upper face of table A intermediate the feed-disk and the main drive-shaft O. The rear end of the beam or rocker-arm E is provided witha roller e, which projects laterally therefrom and is engaged by a cam E keyed to said driving-shaft to make the downstroke of the ram. Said rear end of beam E is also provided with a spiral returning-spring E interposed between it and the table A to automatically perform the upstroke of said ram. F represents an ordinary roll of paper, in uniform strips or lengths of which the successive pieces or blocks of candy are wrapped. This roll is mounted between two rearwardlyinclined bars ff, its shaft or axis bearing in notches at the lower ends of said bars, as clearly shown in Figs. 1, 2, and 3. Barsff are supported by a pair of hangers f f from beneath the rear end of table A and are provided with a transverse roller f journaled in suitable bearings between their forward upper ends.

F is a transverse roller journaled at its opposite ends in rocker-arms F F on table A in rear of a slot or opening F the latter being shown in Fig. 5.

F is a transverse roller mounted in said opening F with its opposite axial ends bearingin boxes f f atboth sides of said opening.

F is a transverse roller mounted within an opening at the center of table A and journaled at its opposite ends in vertically-adjustable boxes f which are controlled or pressed upward by means of springs f", as shown in Figs. 1 and 16.

F is a bow or forked lever whose forward ends are pivotally connected to the axis or shaft of roller F intermediate boxes f and the ends of the roller, and which is provided .with lateral pins or stops f upon which it pivots against the bottom of the table when it is desired to lower said roller on its vertically sliding or adjustable bearings.

G is a roller keyed to a transverse shaft 9 in the upright frame E (previously referred to) vertically above the roller F The face of roller G is preferably roughened, as shown in Fig. 5, to provide a good frictional surface for the proper feeding of the strip of paper, the roller F through its springs f holding said paper up to said roughened roller G with sufficient pressure for said feeding operation. 1

G is a rocker crank-arm loosely mounted on the paper-feed roller G, and g is a vertical link connecting the outer end of said crankarm with the pitman a for its actuation.

g is a pallet or spring-click mounted on the inner face of crank-arm G and engaging a toothed wheel or ratchet g keyed to shaft g for intermittently driving said shaft and its paper-feeding roller at the desired time.

is an upright spring on the table A, forming a detent for the said ratchet g H represents a transverse knife or shear reciprocating vertically in an upright frame It, mounted upon table A intermediate the candy-carrier or feed-disk D and the paperfeeding roller G. At the opposite ends of knife H are suitable pins or gibs which travel in slots or ways in the upright frame h, and upon the backs of said upright, adjacent said slots, are spiral retractile springs h, whose upper ends are attached to said uprights andconnect at their lower ends with the pins which project through said slots, thereby providing means for returning said knife to its upper normal position ready for another out after each downward operating-stroke. The knife is operated by means of arm h which is pivoted intermediate its ends to the front face of said upright directly above said knife, and is in turn operated by a vertical link k pivotally connected at its upper end with one endof a rocker-arm or beam 71 the latter being centrally pivoted to said frame E, and having at its opposite end a roller M, which is intermittently engaged by a cam H secured to the actuating-shaft O.

I represents a suitable printing wheel or drum mounted in upright bearings I 1' upon the rear end of table A and provided with type-receptacles 11 on its face, and 1 is an inking-roller of any desired construction'journaled in the uprights I 1, adjacent said printing-wheel, for applying the ink to the type set up in said receptacles. The printing-wheel I is revolved at regular intervals by any suitable intermittent connection with the actuating-shaft O, the printing of the verse on the paper-feed rolls and the paper itself are at rest.

1 is a spiral retractile spring strained between one of the rocker-arms F and one of the uprights I to properly hold roller F and the paper running over it up to the type on the printing wheel or drum I.

A gravitating weight'or shoe 1 is pivotally connected to the rear end of the bottom of table A and spans the paper roll F, thereby exerting the proper pressure or tension thereon to prevent the paper paying out too rapidly or becoming too loose or slack in the feeding thereof.

The wheel or cylinder B, previously mentioned, has a series of deep peripheral notches or recesses J, constructed at regular and suitable intervals apart to accommodate the succe'ssive blocks of candy or other material to be wrapped, as very clearly shown in the separate views of the wheel, Figs. 11, 12,19, and 20.

J represent U-shaped spring-jaws secured in recesses J, and J are yielding supports or rests for the candy, mounted upon plungers or stems j, which slide in radial holes made in the wheel and the central connecting portion of the spring-jaws J, as shown in Figs. 11, 12, 19, and 20.

j are horizontal pins or fingers projecting outwardly from the innermost ends of plungers j through radial slots 3' in the wheel B, and is a cam secured to rock-shaft 1), adjacent said wheel, with its nose or projecting portion disposed downwardly and in the circular path of said fingersj, the backward or reverse movement of said rock-shaft bringing said nose to bear against the lowermost pin j to force its plungerj and candy-support J outward in position for the last pass in the wrapping operation hereinafter described.

3' is a curved or bow spring attached at one end to the cam 7' and disposed outwardly in a tangential line therefrom, and also in the path pressure on the pins and through them upon the plungers and candy-supports J thereby holding the candy in proper position in said inner face of the paper taking place when theof the said plunger-pins 7", to exert a slight recesses J for the wrapping operation, and making due allowance for any ordinary irregularities in it.

j is a strike pin or cam projecting radially from the hub of cam f slightly in the rear of the nose of said cam and provided with an inclined or beveled outer end which is engaged by the said plunger-fingers jand properly guides or forces them outward to the extreme end of their slots, thereby bringing the yielding supports or rests J up to their normal positions and throwing open and holding their jaws J apart for receiving the candy from the ram and feed-disk in the feeding operation.

K K represent a pair of cam-tracks or guideways attached to the hind legs of frame A and projecting inwardly therefrom (see Figs. 1, 3, i, and 30) and has the forwardly-extending lips I0 on its forward face, which serves as a guide for the rollers m K is an upright cam-track mounted upon the rear end of base-plate A and having its face or operating edge constructed the greater part of its length in a curve concentric with the rock-shaft 1), its upper end beinginclined or beveled rearwardly and its lower end depressed or running slightly backward, as shown in detail in Fig. 13.

L is an upright curved arm or track, also concentric with said rock-shaft b and secured upon the rear end of said base-plate A adjacent said cam-track K and in line with the center of the peripheral face of wheel B a suitable distance in rear thereof, for the purpose I shall presently describe.

Z is a bifurcated presser-arin projecting from the upper end of the upright curved arm L and curved or bent downwardly and rearwardly in in verted-U shape, also hereinafter referred to in the description of the operation of the machine.

L L are two rings, one of which is attached to each side of the wheel B by means of screws Z and spacing sleeves or tubes Z as clearly shown in Figs. 4, 11, 12, and 20.

L represents each one of a series of folderplates on the periphery of wheel B. Each of these folder-plates is mounted at one end upon the crossbar of a stirrup or U-shaped arm L whose arms span said wheel radially and are pivotally connected at their inner ends with both sides of said wheel, so as to move over the said jaws J in the folding operation.

Z Z represent short lateral extensions or pins at the fore or free end of each of said folder-plates L to engage the full width of the paper (more or less) in making the first fold in the wrapper.

L is a flatplate-springsecured at its rear end to the fastened end of each of the folder-plates L and exerting a suitable amount of pressure at its inwardly-bent portion on the said folder-plates to hold them down upon the first fold in the paper and the latter down upon the candy during the succeeding step in the wrapping operation, which is that of making the other longitudinal fold in the paper.

L represents each one of a series of folderplates on the periphery of the wheel B, adjacent each of the recesses or jawsJ on the peripheral side opposite to that occupied by each of the said folder-plates L Z 1 represent each pair of a series of radial bars or arms pivoted upon both sides of the wheel B and having at their outer ends the folder plates L. each one being pivotally mounted at its rear forked end therein and provided with a roller or trundle L in said forked end, which rides upon the upright circular track or arm L, thereby operating one each of both said sets of folder-plates L and L simultaneously through the interposition of connecting rods or links I, as shown in Figs. 3 and 19, the uppermost one of the folders L being operated forward and making the first fold in the uppermost candy-wrapper while the folder L, immediately preceding it, is being operated backward and making the second fold in the candy-wrapper ahead of said uppermost one. The connecting rods or links Z aforesaid are on one side of the wheel Bonly, and each one is pivotally attached at one of its ends to one of the inwardly-disposed arms of the stirrups L intermediate the ends of said arm and at its other end is similarly attached to an inwardly-disposed extension, which is constructed on each of the radial arms Z on said side of the wheel only. A spiral or retractile spring Z is stretched between each of the connecting-links Z (at the end which is attached to stirrups L and a pin or support Z on the inner face of the adjacent ring L, as shown in Fig. 4:, for automatically and immediately returning the several folders to their normal positions succeeding each movement thereof.

L is a plate-spring attached to the forked ends of each of the folder-plates L and disposed forwardly on the periphery of the wheel B, its free end bearing upon the face of said wheel, and thereby maintaining a suitable pressure on each of the said folders L to hold it down upon the fold it has made in the wrapper until the succeeding step in the operation.

M represents each one of aseries of folding fingers or tuckers mounted in circular series on both the rings L L, normally projecting in a radial line therefrom. These tuckers have cylindrical heads and are made L shape, being pivoted in the angle of the L to the inner ends of the radial portions of angular plates or supports M, attached at suitable intervals apart on the periphery of both said rings.

M represent each one of a series of bars or levers pivotally connected at its outer end upon the outer end of the radial part of one of said angular supports M and having a notch m at its inner end in which plays an upright pin or screw m on the inner end of one of the said L-shaped tuckers, a small spiral or retractile spring 171 being stretched between the top of said pin or screw m and a screw m on said lever M to properly maintain said tuckerin its normal position. Rollers on, mounted on studs projecting outward at right angles to levers M at their outer ends, ride upon or engage the said cams or guideways K K, thereby operating the tuckers M both to and from the end fold in the paper wrapper, as hereinafter more fully mentioned.

N N represent each pair of a series of folder-fingers on the cylinder B for making the fold on one side of both ends of the wrapper, and O O are each pair of a series of similar folder-fingers for making the fold on the other side of both ends of said wrapper. Each pair of said folders N N and O O are firmly mounted upona short shaftn and 0, each of which passestransverselythrough the wheel B, adjacent one of the lower corners of the re spective recesses J aforesaid, folder-fingers N and 0 being mounted at one end of each of said short shafts on one side of the wheel and folder-fingers N and 0 being at the other end of each of said shafts on the other side of said wheel. Folder-fingers N, N, O, and O are mounted intermediate their ends upon their shafts n and 0, respectively, the inwardlydisposed ends of each set of fingers N and 0, adjacent each recess J on one side of the wheel, being connected by a link N which prevents said fingers coming in contact, and one of them 0 moving toward the said recess when the other N. is performing its operation on the wrapper, the slot N in the end of said link, connecting with folder 0, being provided to permit the necessary play therein at the proper time.

On the opposite side of the wheel each of the fingers N is mounted at its inner end on one of the short shafts n and is pivotally connected with the inwardly-projecting end of the preceding finger O by means of a rod or link 0 so that a set of each of the folder-fingers N N and O O operate simultaneously, the former set (fingers N N) making the aforesaid fold on one side of both ends of one wrapper while the latter set (fingers O O) are makingasimilar fold on the other side of both ends of the wrapper ahead.

A spiral retraotile spring P is stretched be tween each set of folder-fingers N N and those ahead 0 O on one side of the wheel by connecting its ends with the fingers N and O, as shown in Figs, 1, 2, 4, and 17, thereby sustaining said fingers in their normal positions and also automatically returning them to such normal positions after each operation on a wrapper. These springs P act as auxiliaries for the links N to return said fingers to their normal positions, as stated. A roller a is mounted on a stud projecting laterally from the outer end of each folder-finger N and engages the cam-track K aforesaid to cause the operation of the folder-fingers in the rotation of folder-carrier wheel B.

Q represents a vertically movable flatheaded pedestal at the middle of the discharge-table A in a perpendicular line with the feeding-ram D and the uppermost and lowermost candy-recesses J of the folder-carrier wheel for receiving and supporting the wrapped candy during the last pass in the wrapping operation. This headed pedestal or stem passes downward through a central opening in the discharge-table and the bore of a box R, the latter having a circular upper end or shank 0, which fits in an enlargement or block 1* on the bottom of the said dischargetable below its said central opening and is detachably secured therein by a screw W, as clearly shown in Figs. 7, 8, 10, and 20. The lower portion of the stem of pedestal Q is of less diameter than the upper and is provided within box R with an encircling spiral spring R, the expansive pressure of which properly supports the pedestal and at the same time permits it to yield the proper distance when a downward pressure is brought to bear on its head, as hereinafter described.

R is a rectangular sleeve or sliding box surrounding the box R and provided with two vertical arms R R whose lower ends are pivoted in bearings r at the lower ends of both sides thereof, as clearly shown in Figs. 7, 8, and 20. Said arms R project through transverse slots R in the discharge-table A and have shouldered jaws R at their upper ends which make the last pass in the wrapping operation and also grasp the wrapped candy, holding it on the yielding or springsupported pedestal until finally ejectedor discharged through the large opening R in said discharge-table.

r is a pendent plate-spring secured at its upper end to the upper end of box R and exerting its pressure at its lower end on the transversely-ohanneled face r of said sliding box B thereby serving as a temporary frictional device for maintaining thejaw-arms R in either their closed or open position in relation to the wrapped candy at the close of the wrapping operation.

S S represent two knee-shaped arms projecting from a transverse rock-shaft S beneath said discharge-table, said rock-shaft being journaled in bearings at the fore end of said discharge-table and having at one of its ends (which projects a suitable distance beyond the discharge-table) an upright lever or arm S connecting by a horizontal rod or link S with the pitman a for its actuation.

8 represents a transverse bar connecting the free ends of arms S S, thus practically forming an actuating-stirrup forthe discharge mechanism.

S S are inwardly-disposed plates secured upon the inner faces of said free ends of arms S S and provided with inclined cam-slots .9 8 into which project pins 5 s on the upright jaw-arms R R for performing the functions of closing said jaws R and throwing them apart, and also reciprocating the sliding box R on the box R.

T represents a pair of upright arms connected by a cross-bar T, the latter being secured centrally upon the lower end of the pedestal-stem Q, as shown in Figs. 4, 7, S, and 20. These arms embrace both sides of the box R and slide freely up and down thereon in the operation of the device, in contactwith the bottom of sliding box R their principal object being to prevent the turning of said pedestal in its guideway or hearing at any time, thus especially obviating any improper acci dental shifting of the wrapped candy in the closing step of the wrapping operation. An upright pin 25 upon thetop of one of the arms Tand sliding in a hole in one of the bearingboxes 9', as shown in Fig. 7, may be provided as an extra precaution to prevent the turning of said pedestal for the object above mentioned.

The operation of the machine is as follows: Fig. 2 illustrates the various parts in the respective positions they assume immediately after the ram D has fed or delivered a block of candy or what is commonly called a sugarkiss or a caramel, with its open wrapper, into the uppermost recess or jaw T of the cylinder B, lowering or depressing the yielding supports or rests J ahead of it. The longitudinal portions of said wrapper are shown standing upright from said. jaw in the said view. (Also shown in Fig. 23.) Motion being imparted to driving-shaft C in the direction of the arrow, the downstroke of the pitman a actuates the rocker-arm a which in turn actuates rock-shaft 11, carrying the cylinder B a sufficient distance to bring the next jaw or recess J in said cylinder under the guideway of the ram. During the said limited movement of the cylinder B and downstroke of the pitman the following movements of certain parts of the machine take place: Immediately upon the starting of cylinder 13 the roller L adjacent the jaw J, which is just ahead of said uppermost jaw, engages the cam-track L and, through the medium of one of the extension radial arms Z and connecting-rods Z, simultaneously brings the peripheral folder-plate L lying back (to the right) of the upwardly-projecting portion of said uppermost wrapper, forward over the candy,

thereby making the first fold in the said uppermost wrapper, Fig. 24. At the time said roller L starts to engage the said cam-track L it causes its adjoining folder L to move backward over its adjoining jaw, thereby making the second fold, Fig. 25, in the wrapper of the candy just ahead of said uppermost one simultaneous with the making of said first fold in the latter. Simultaneous with the initial engagement of said roller L tions of the wrapper, afterward constituting the second fold therein, thereby laying the said portion of the wrapper in position, ready for the next engagement therewith of the folder L The arm Z is bifurcated or forked, as shown and hereinbefore described, for two purposesviz., that of presenting a broad guide for the full width (more or less) of said second fold in the wrapper, and also providing an opening through which the projecting rollers L on the cylinder B may pass without obstruction. Simultaneous, also, with said initial contact of said roller L with the cam-track L the roller L just ahead of it has reached the end of its stroke at the lower end of said cam -track, one of the springs Z, which has been expanded or stretched by said stroke of the last-mentioned roller L now withdraws or retracts the folder L from the second fold in the candy-wrapper adjacent said lastmentioned roller L and also the folder L from the first fold in the candy-wrapper adjacent the immediately-succeeding roller L at the top of said cam-track. Immediately after the folder L has made the second fold in the wrapper at the startof of the engagement of its adjacent rollerL with cam-track L a pair of the tuckers M on the rings L L at both sides of the cylinder are brought into engagement with the upper opposite ends of the now longitudinally-folded wrapper, thereby laying said upper ends down upon the ends of the candy, Fig. 26, ready for the side laps or folds of said opposite ends. This movement of the tuckers M is caused by the rollers m mounted on their actuating-levers M engaging the cams or gnideways K K, their return movement to normal position being caused by continuations of said guideways and the small spirals m Ator about the time the tuckers M have performed their function and at or about the middle of said downstroke of the pitman the vertical jawarms R are thrown open on their respective axes through the instru mentality of the kneeshaped arms or levers S S, whose rock-shaft S is so turned by the upright arm S and rod or link S the latter connecting upright arm S with said pitman as to rock said levers S upward a portion of their full stroke only, thereby also permitting the spring-controlled pedestal Q to rise very slightly. The jaws R at the upper ends of said arms R being spread apart at this moment and the pedestal Q supporting the wrapped candy in the open-- ing between them, the next succeeding roller L on the periphery of the moving cylinder B passes unobstructed through said opening between said jaws and ejects or throws said wrapped candy from the pedestal Q, which candy escapes through the opening R in the discharge-table into any suitable receptacle beneath. Simultaneous with said movement of the roller L in ejecting the candy from pedestal Q motion is imparted to the notched feed-disk D by the slide-bar D and its pallet (1 they in turn being operated by the link D crank-arm D and the wheel rock-shaft b,

as hereinbefore explained.- Said motion is of sufficient length to bring into the downward path of the ram D the candy-filled pocket d, lying next to the empty one previously under said ram and which held the candy in the said uppermost jaw J on the wheel. The motion necessary to complete the distance between the pockets din said feed-disk and carry each successive candy up to the ram is sufficient to bring the pitman to the end of its downward stroke, and simultaneous with that motion the jaw-arms R are raised, spread wide open as high as they will go in their up- Ward movement, together with pedestal Q. ready for the last pass in wrapping the next piece of candy. Simultaneous with the entire downward stroke of said pitman the roughened roll is revolved for feeding the strip of paper under the lipped projection 01 on the feed-disk, bottom plate, or track (1 ready for the next candy in the feed-disk. Motion is imparted to said roughened paper-feed roller G by means of rocker crank-arm G, loosely mounted on its shaft g, and the vertical link g, connecting said crank-arm G with the pitman for its actuation. Said rockerarm G is intermittently coupled with the roller-shaft g by means of the pallet g engaging the ratchet or toothed wheel 9 keyed to said roller-shaft, thereby communicating similar intermittent motion to said shaft and its paper-feed roller. In the intermittent forward movement of the cylinder B and the said downstroke of the pitman the pinsj, projecting from the inner ends of plungers J j on one side of said cylinder, assume the positions shown in Fig. 2. At or about the middle of said downstroke of the pitman a set of each of the end folder-fingers N N and O O operates simultaneously on the two candywrappers just ahead of said uppermost one. In their operation roller n on the folder-finger N, now adjacent the upper end of the camtrack K, engages the upper inclined end of said cam-track K immediately following the completion of the full stroke of the tuckerfingers M, above described. At the time said roller n begins to engage said cam-track it simultaneously brings into operation its adjacent set of fingers N and N and the set of fingers O 0, adjacent the jaw or recess J immediately preceding, and holds said fingers in contact with the folds they make in the ends of both wrappers (see Figs. 27 and 28, respectively) until it reaches the depression at the lower end of said cam-track when it is released, at which time both saidsets of tingers return to their normal positions through the reaction of their spiral connecting-spring P, the slotted link N bringing the set of folders O and O to said normal positions at said time. At the termination of the downstroke of the pitman, when the paper has been fed the proper length for a wrapper, the shear H immediately begins to descend and, during the initial upstroke of the pitman, completes its work of cutting said length through the medium of the arm 71 vertical link if, and rocker-beam 72 the latter having roller 71, which is intermittently engaged by cam H on the actuating-shaft C for said cutting operation. The shear is automatically returned to its normal position immediately after cutting said paper by means of the retractile springs h, as hereinbefore fully described. At or about the middle of the upstroke of the pitman the jaws R at the upper ends of arms R close on the upturned folded and pointed ends of the lowermost wrapper, their shouldered portions engaging said upturned ends or points and laying them down over the corners on the back of said wrapper, Fig. 29. The said arms R with the Wrapped candy embraced between their shouldered jaws R and the head of pedestal Q, now descend with said pedestal and assume position for the proper ejectment of said wrapped candy, as hereinbefore described. During the latter half of the upstroke of the pitman the slidebar D and its pallet d return to their normal positions with said pallet in engagement with the next tooth of the feed-disk D, ready for carrying the candy (immediately following that now under the ram) forward under said ram for the wrapping operation. The downstroke of said ram takes place during the said latterhalf of the upstroke of the pitman, driving or delivering the candy lying in the pocket of the feed-disk into the now uppermost recess of the cylinder. The reaction of spiral spring E returns said ram to its normal position at the upper end of its raceway D at the time the pitman is about to begin its downstroke and when the cam E has just passed or released the roller e on its operating-beam E. The passage or direction of the paper in feeding to the ram-opening above the cylinder is clearly shown in Fig. 2 and needs no detailed description herein other than that given in connection with its guide or supporting rollers, hereinbefore fully described. In said Fig. 2 the end of the paper is shown under the lipped tongue (1 of the feed-disk track (1 ready for the next cut of the shear.

The purposes and operations of the other detail parts are fully hereinbefore described and will need no further detailed reference here.

I claim- 1. In a wrapping-machine, the combination of a revolving folder-carrying wheel or cylinder mounted upon a shaft within a suitable frame, a feeding-table above said cylinder, a revolving feed-disk and ram on said table, paper-feeding mechanism on said table, a discharge or base plate below said cylinder, a receiving or holding pedestal and arms or jaws on said baseplate, and suitable cam and crank driving mechanism for actuating said parts, constructed, arranged, and adapted to operate substantially as herein set forth.

2. In a wrapping machine, a revolving wheel or cylinderB, mounted on a rock-shaft, carried by a suitable frame and having radial recesses J in its periphery at suitable intervals apart, spring-jaws J, forming the opposite end walls of said recesses, yielding plungers J forming the bottoms of the jaws for receiving and supporting the respective arholes to be wrapped and their wrappers, pins or lingers j, project-in; from the innermost ends of said plungers J 7' through radial slots in said wheel, earn j on said Wheel-shaft, curved or bow spring j on said cam, and strilie-pin j, also on said cam in rear of its pro ecting portion, and mechanism for intermittently revolving said wheel on said shaft, substantially as herein set forth.

3. In awrapping-lnachine, the combination, with a revolving wheel or cylinder 13, in whose periphery are constructed recesses J, having yielding holder-jaws which are self-conforming to ordinary irregularities in the articles to be wrapped, and means for operating the yielding bottoms of said selfconforming jaws, of peripheral folder-plates L and L side folder-fingers N N and O 0, rings L L on the'opposite sides of said wheel, folding fingers or tuckers M on said rings in line with said recesses or jaws J projecting rollers L on said folders, and cam-tracks K K K L, said folder-fingers, and also the tuckers, being suitably mounted on the wheel and rings, respectively, and all the parts being arranged, connected, and adapted to operate substantially as herein set forth.
