For convenience, in describing the relative locations of parts of the device, that end of the machine to which the letter A is applied in Figure 1 will be referred to as the forward end, the rear end being marked by the letter B.

The machine embodies a frame which, as a whole, is designated by the numeral 1. The frame may be fashioned in various ways, with out departing from the spirit of the invention. Those portions of the frame which have significance and importance will receive appropriate designating numerals, as the description proceeds.

General driving mec-7zam7sm.An electric motor 2 is mounted on the frame 1 and is lotended through the casing 6. The casing 6 is adapted to contain oil for the purpose of lubricating many parts that are inside the casing, as Figure 8 will show. It is from the shaft 9 that the various constituent mechanisms of the machine are driven.

- The print feecZ.-Noting the upper righthand portion of Figure 4, it will be observed v that the prints or blocks of butter are fed into the machine by an endlessconveyor 16, and

for the actuation of the print feeding means, a double crank 10 (Figures 7 and 3) is mounted (Figure 8) on one end of the shaft 9. A long, upwardly extended connecting rod 11 is pivoted at its lower end to the crank 10.

' Ashaft 14 (Figures 3 and 8) extends transversely of the frame 1 and has a rocking movement therein, through an arc of about ninety degrees, a crank arm 12 being secured to one end of the shaft, andthe crank arm being pivoted to the upper end of the connecting rod 11. A sleeve 19 (Figures 8 and 24) is rotatable on the intermediate portion of the shaft 14. The sleeve 19 has a sprocket wheel 15 about which is engaged an endless conveyor 16 cooperating with an idle sprocket wheel 17 carried by a shaft 18 which'is supported (Figure 2) on one'end of the machine.

Reverting to Figure 24, in comparison with Figure'S, it willbe noted that two sleeves 21 are secured to the shaft 14 and are located on opposite sides of the rotatable sleeve 19. The sleeves 21 have outwardly projecting radial guides 22 in which plungers 23 can slide, parallel to the shaft 14. The plungers 23 are supplied at their inner ends with heads .24 which, as shown in Figure 3, are located at the inner or rear end'of the conveyor 16. The plungers 23 carry angular brackets 25, the ends of which slide in the innermost guides 22. The plungers 23 and theprint-gripping heads 24 are'pressed toward the longitudinal center of the frame lby springs 26. The brackets 25 cooperate with ratchets 20 on the ends of the sleeve 19.

Operation of the print fee(Z.The motor 2 is put into operation by means of the switch 3 and rotates'the shaft 5, the worm 7 and the worm wheel 8 rotating the shaft 9, and the crank 10 actuating the connecting rod 11, oscillatory motion being imparted to the shaft 14 by way of the crank arm 12. /Vhen the shaft 14 is rocked, the sleeves 21 are rocked also. When the sleeves 21 are turned clockwise in Figures 24 and 3, through an arc of about ninety degrees, the brackets 25 cooperate with the ratchets 20 to turn the sleeve 19, the sprocket wheel 15 actuating the conveyor 16 and causing the: prints of butter to be moved to theright in Figure 3 or to the left in Figure 4. During this movement, the innermost print of butter, marked by the numeral 44 in Figure 4 is gripped at its ends by the heads 24. The print 44 of Figure 4 is carried down, by the heads 24, underneath a vertically movable ram 27, to be alluded to hereinafter. By the time that the print of butter is well underneath the ram 2?, the direction of oscillation of the crank 12 of Figure 3 is reversed, and the brackets 25 start to climb up the inclined; surfaces of the ratchets 20.

When the brackets 25 climb up the inclined surfaces of the ratchets 20, during the counterclockwise rotation of the shaft 14 and the guides 22 assume the vertical position of Figure 3, the brackets 25 snapping into engagement with the depressions of the ra-tchets 20, under the action of the springs 26. The heads 24 have now gripped another print of butter at its ends, on the conveyor 16, and the parts are set to rotate the sleeve 19 clockwise in Figures 24 and 3, so as to bring the print down under the ram 27, as has been mentioned hereinbefore.

The mm.The ram 27 (Figures 8 and 4) is in the form ofa block, attached to a skeleton slide28 mounted for vertical reciprocation in guides 29 on the frame 1. The upper end of pitnian 30 is pivoted to the slide'28, the pitman extending downwardly at one side of the machine. The pitman 30 has a loop-shaped lower end 31 (Figure 3) receiving ashaft 32 (Figure 8) journaled in the frame 1. The shaft 32 serves as a means for guiding the vertical movement of the pitman 80, although the shaft has other important functions.

It appearsfrom Figure 3 that the pitman 30 has'an offset 38 at its lower end, and to this offset are pivoted links 34 which, in their turn, are pivoted to a crank 35 secured to a transverse shaft 36 (Figure supported for rocking movement on the frame 1. An arm 37 is secured to the shaft 36 and carries a counter-weight 38. A rearwardly extended arm 39 is secured to the shaft 36, the arm 39 being pivoted to a link 46 (Figure 4) con nected by a pull spring 41 to the casing 6. T he link 40 is pivoted to a slide rod 42 mountcl to reciprocate horizontally inthe casing 6 and provided with a roller (not shown) that bears against a cam 43 (Figure 8) on the shaft- 9.

Operation of the mm.-The ram 27 moves vertically as the slide 28 reciprocates in the guides 29, the pitman 30 actuating the slide, and vertical motion being transmitted to the pitman from the shaft 36 by the arm .35 and the links 34 of Figure 3. The shaft 36 receives motion from the power driven shaft 9 of Figure 8 through a train of parts including the cam 43,the slide rod 42, the link 40, and the arm 89, on the shaft 36.

The paper feecZ.Horizonta'l guides 45 (Figures 21, 2 and 6) are mounted on the frame 1. A bracket 46, which is U-shaped in plan, extends rearwardly from the guides 45. A. slide 47 is mounted to reciprocate on the guides 45. Links 48 (Figure 4) are pivoted to the slide 47 and to arms 49 that extend upwardly from a transverse shaft 50 (Figure 6), the shaft having depending arms 51 to which is pivoted a pitman 52 (Figure 4) connected to a crank 53 on a shaft 54 (Figure 5) journaled'on' thefranie 1. Ansprocket (Figure 2i) has inwardly- 58 in gripping-the piece of paper 89 which is v to be wrapped about the block of butter.

The shafts 60 are provided at their rear ends withcranks 62 (Figure 2) to which are pivoted inwardlyiextended' pitmen 68 (Figures 21 and 22) the inner ends of the pitmen being pivoted to a crank disc 64 on a shaft 65 rotatable in abearing 66 carried by the slide 47. v The shaft 65 can rotate and slide longitudinally in a bearing 67 on the bracket 46 which forms part of the fixed frame work .of the machine; A spring-68 (Figure'22) is secured to the crank disc 64 and'to the slide 47. When the sp'ing 68' is inclined to the left, as in Figure 22, the spring tends to hold the jaw 61closed with respect to the jaw 58 on the paper 89, but when the crank disc64 is rotated far enough in the direction of the arrow in Fi ure 22, then the spring-68 will incline to the right hand side of-the center of rotation of the disc 64 and tend to hold the jaw 61 in open position with respect to the jaw 58' and thepaper 89. A cam 69 (Fig ures 21 and 1) is mounted onthe rear end of the shaft 65, and a cam 70 is mounted on the forward portion of the shaft, the cams being held in place by set screws on the shaft 65 for circumferentialadjustment. The earns 69 and 70 cooperate, one at 'a time, with the bearing 67 of Figure 21, to rotate the shaft 65,.ina way which will be described hereinafter. i

Supports 71 (Figures 1 and 2) are mounted on the rear end of the frame-1 and carry a roll 72 of paper, whereof the piece shown at 89 in Figure 22 is a part. An upwardly and forwardly extended table 73 is mounted on the rear end of the frame 1 and carries a paper guide 74 which need notbe described in detail, becauseit may be of any approariateconstrtiction; The .aaner 'roceedin L 7 O hold on the piece of severed paper which is :to be wrapped around the butter. By the operation last-above described, the pull spring 68 of Figure 22 is swungto the right of the center of rotation of the crank disc 64, and holds the jaws'61 open. With the jaws '61 opened, the slide 47 is moved to the left in Figure 21, and the jaws 61. and 58 are disposed respectively below and above the end of the piece of paper that has not yet been cut off from the roll 72, or been advanced into the position shown in Figure 21. When the slide 47 moves far enough in Figure 21, so that the cam 70 cooperates with the bearing 67, the shaft 65 is rotated, and the jaws 61 are closed on the paper, the spring 68 returning to the position of Figure 22, to hold the jaws 61 in engagement with the paper. The slide 47 then is carried to the right in Figure '21, and the operation is repeated, length after length of paper being unreeled from the 'roll 72, and cut off, as the rain 27 shoves down piece after piece of butter, for wrapping.

The slide 47 is reciprocated bya train of parts including the shaft 9, the sprocket wheel 57 (Figure l), the :chain 56, the sprocket wheel 55, the shaft 54, the crank 53, the pitman 52 (Figure 5) the arms 51 (Figure 6), the shaft 50, the arms 49 (Figures 1 and 6),andthelinks 48.

The cutting mechanism.-The wrapping paper is advanced across a fixed blade (Figure 4) supported by the frame. .A movable shear 76 (Figure 7) cooperates with the fixed blade 75 to cut off a length of the wrapping paper. The movable shear 76 is fulerumed at 7 7 on a bracket 78 of L-shape carried by one side of the frame 1. A connecting rod 79, shown to good advantage in Figures 7 and3, is pivoted at its upper end to the intermediate portion of the shear 76. The rod 79 is raised, and the shear 76 elevated, by a strong compression spring 80 connected to the horizontal part of the bracket 78 (Figure 7) and to the rod 79. Upward movement of the shear 76 is limited by the engagement shown at 92 in Figure 7 between the shear and the vertical part of the bracket (8.

The lower end of the rod 79 is pivoted to I an arm 81 (Figure 3) on a shaft 82 (Figure 5) mounted to rock in the frame 1 and offset at 83 to clear the motor shaft 5. The shaft 82 has an arm 84 igure 4) .to which is piva,eso,37s V 85, the arm 84, the shaft 82 (Figure 5), the

.arm,81, and the connecting rod 79 of Fig ures 3 and 7. The weight of the shear 76 and attendant parts aids in bringing about the downward movement of the shear, the spring 80 assisting in elevating the shear.

The rotor 01* print'camier.Tlie rotor or print carrier 93 is shown in its place in the machine in Figure 4, and appears in many other figures of the drawings, for instance, Figures 18, 20, and 8. cured to the shaft 32 and turns therewith. The rotor 93 has longitudinal seats 94. These seats 94 pass, one after another, under the vertically movable ram 27 (Figure 9), and a 5 the bearings 95 and carries arms 97in which a stop roller99 is journaled. A retractile The rotor 93 is sespring 98 is connected to one of the. arms 97 and to the casing 6, the spring keeping the roller in frictionalcontact with the periphery of the rotor 93.

A ratchet wheel 100 (Figures 3 and 2) is secured to the shaft 32. A. pawl 101 cooperates with the ratchet wheel 100 and is carried by a wheel 102 rotatable on the shaft 32. A connecting rod 103 is pivoted to the wheel 102 and to the crank 10 (Figure 8) on one end of the main shaft 9.

Operation of the r0t0r.-The roller 99 (Figure 23) engages in one of the seats 94 of the rotor 93 to hold another of the seats 94 directly under the rain 27 of Figures 9 and 7. When the ram 27 comes down, it Carries the ;print 104 of butter into the uppermost seat 94 of the rotor 93 with the severedsheet 105 of paper around the print, as shown in Figure 26. The rotor 93 is turned, a quarter of a revolution at a time, by the shaft 32, the C,

ratchet wheel 100 that is fixed to the shaft 32, h

the pawl 101 on the wheel 102 that turns on the shaft 32, the connecting rod 103, and the crank 10 on the shaft 9.

Structure and operation of the folding shape, as shown in Figure 26. Referring to which has limited movement on the periphery of the rotor 93 (compare Figures l'Oand 12). The roller 107 isfjournaled in a yoke 108 which is pivoted. to a slide orrod 109,

meunted toreciprocate in a guide" (Figure 1) 110 supported on the main frame 1 of the machine. The slide 109 is pivoted to a link 111 which, in its turn, is pivoted to an up.- standing arm 112, on a sleeve 114 (Figure '5 the sleeve bein -mounted to rock on the shaft 36. The shaft-carried sleeve 114 has a depending arm .115 (Figure 1) pivoted to a link 116, the link being pivoted to a slide.

ure 10, i forms the fold 106 of Figure 11,

the rollerl07 being operated by the yoke 108, the slide 109, the link 111, the arm 112, the sleeve 114, the arm 115, the link 116, the slide rod 117, and the cam 119 onthe main 5' shaft 9.

After the fold at 106 has been made, the next operation is to turn up thefirst end flaps i 126 of Figure 13; The mechanism for doing this comprises plungers 128 (Figures '8and 5 1.2) that reciprocate vertically in guides 129 on the frame work of the machine. The lower ends'of the 'plungers 128 are pivoted to slide rods 130 that move vertically in the casing 6, the rods 130 carrying rollers 131 cooperating with cams 132 on the main. shaft 9. The upper ends of the plungers 128 are offset inwardly (Figure 12). On the upper ends ofthe plungers 128, levers 133 are fulcrumed intermediate their ends, as-shown in Figure 8. On the outer ends of the levers 133, rollers 127 are journaled, rollers 134 being journaled on the inner ends of the levers 133. The rotor 93 is hollow, so that there are circular tracks 135 (Figuresg20, 8 and 12) in the ends of it. Pull springs 136 (Figure 3) are secured to the guides 129 and to the outer ends of the levers 133. i

The springs 136 tend to keep the rollers 134 in engagement with the tracks 135 of the rotor 93. When the plungers 128 are raised by the cams 132, the rollers 131, and the slide rods 130, the roll'ers134 act as fulcra for the levers 133, and swing the levers, so

that the rollers 127 are carried inwardly and springs 136 restore the levers 133 and the rollers 127 to the position of Figure 8.

Thenext operation is to turn in the second end flaps 137 of Figures 15 and 14. For the doing of this, there is provided a mechanism including slides 139 (Figures 4, 8 and '16) which have right line reciprocation in guides 138 on the framework of the machine. Arms are'pivoted to the slides 139 and carry rollers 141 which turn on vertical axes. I Torslon springs 142, engaged with the arms 140 and with the pivot elements thatattach the arms to the slides 139, cause the arms. 140 to swing inwardly, thereby holding the'rollers 141 yieldably against the ends of the rotor 93, as shown in Figures 12 and'8.

Angular links 143 (Figures 4 and 14) are pivoted tofarms 144 on sleeves 145 (Figure 8) mounted to rock on stub shafts 146 carried .by the frame 1. The sleeves 145 have de pending arms 147 which are pivoted to links 148, the lower ends of the links being pivoted to slides 149 carrying rollers 150that cooperate with cams 152 on the'main shaft 9.

When the shaft 9 operates the'cams .152,

the slides '149 and the links148 move upwardly, the sleeves 145 being rocked through 'the instrumentality of the arms 147 on the sleeves, the arms 144011 the sleeves moving the slides 149 to the left in Figure 14, the rollers 141 turning over the second end flaps 137. The retraction of the rollers 141 from the position of Figure14, aftertheflaps'137 have been made, need notbe gone into, because it-is controlled by the cams 152 of Figure 8, in a way readily understood by anyone familiar with the function of'a cam.

By the" time that the wrapping operation has, reached the point shown in Figures'14 and 15, one end 106 of the piece of paper has been turned down. The opposite end 153 of the piece of paper is still sticking up). The means forfolding down the end 153 of the piece of paper is simple. It embodies a roller 154 (Figure .2) extended cross-wise of the machine andjournaled'on levers 155 mounted to'swing on the frame and pulled down by springs 156 (Figure 1) attached to the said levers, and to the. frame work, the con struction being such that the roller 154 rolls 5 on the rotor 93. The rotor 93, as it'turns,

carries the end 153 of the paper under the roller 154. The end 153 of the paper is shown partly flattened down in Figures 16 and 17,

but by the time that the rotorhas turned 1:.

clockwise through an arc of ninety degrees,

from the position of Figure 14t-o the position of Figure 18, the end 153 of the paper is folded down closely on the'end 106.

Third d p 5 eXiSt in the wrapping paper and the flaps 157 must be turned down .wise from the position of Figure 14v to the 5' position of'Figures 18. The mechanism for turning over the third end flaps 1 57 preferably embodies a support in the formof atransverse bar 158 (Figure 7) mountedon the framework 1. Levers 159 are fulcrumed ion thesupport 158 and carry rollers 161 constrained'to bear against the ends of the rotor '93 by a pull spring 160 which connects the levers 159. As the rotor 93 moves from the position of Figure 14 to the position of Figure 18, the outstanding flaps 157 of Figure 17 pass under the rollers 161 and are folded down tightly as shown in Figure 19. There now exists a fourth end fiap 162 J to be bent over, but the bending over of this flap will be considered in connection with the operation off'the-ejector mechanism.

The ejector 7necham'sm.-In describing the ejector mechanism,.attention is called to the fact that, in Figure 8, the main shaft 9, is shown as provided with a cam 163 which operates a slide rod 164 (Figure 3) mounted to reciprocate horizontally in the casing 6 and pivoted to a link 165, the link being piv- Qted to an arm 166 on a-sleeve 167 (Figure 5;) mounted to rock on the shaft 83.. The sleeve 167 has an upstanding arm 168' (Figure 4), and a pull spring 171 connects the said arm with the rear portion of the frame 1', as Figure 2 discloses. A link 169 is pivoted tothe arm 168 and is pivoted to a horizontally movable bell crank lever 170 (Figure 5) fulcrumed on the frame. The'long army of the bell crank lever 170 is pivotally connected at 172 with an L-shaped slide 173 (Figures 14 and 4) that moves crosswise of the machine on a track 176, which may; be a; channel bartto be seen in side elevation in Figure 7, and. in end elevation in Figure 1. An inner shoe 17'4 (Figures 7', 16 and 5) issecured to the slide-173' and 'reciproeates within the track, 176. Outer rollers 175 are jburnaled on the slide 17 3 and engagethe track. 17 6%externally (Figures- 5' and 18).

The. ejector (Figures 12, 1,, and 20) is marked by the numeral 177, and may. be a block, attached to the slide 173'. Theejector 177 is so locatedthat it will shove the partly wrapped. print 120 of Figure 20 lengthwise off the. seat 94 in the rotor 93, and into a chute 178 carriedby the frame. One of the fourth end. flaps 162 is turned over by contact with the ejector 177 and the other of the, fourth end flaps is turned over by contact with. a preceding print thathasbeen transfer-red. to the chute 178, and bythe time that the print is in the chute 178, bothof' the flaps 162. have. been folded against the ends of the print,.approximately as shown at 180, thecompletely. wrapped print being marked by the numeral 17 9in Figure 20.

As to-the final foldingof the wrapper, at the ends, the finalfolds are completed when the butter is placed in the carton. Even though the ejector does not effect a perfect 184 on the frame.

rscgsv wrapped, in' theflsense that it is completely covered by the paper, even though the final foldlmaynot assume the perfection and symmetry of the folds 137'and" 157, for instance,

in Fig. 19 of the drawings.

' Operation. of the ejector-The ejector 177 is operatedby a train of parts including the cam 163, the slide rod 164, the link 165, the arm 166, the sleeve 167,. the arm 168, the link 169, the bell' crank 170, and the slide 173 which is held by the shoe 17 4 and the rollers 175 for reciprocation on the track 176.

The delivery conveyors-As the completely wrapped print'179, of. Figure 20, moves out of thechute 178, the print passes upon" an endless delivery carrier 181 (Figures 1, 8, and 2), that. extends backwardly toward the rear end of. the machine. The conveyor 181 is carried. by an idle drum'182 journaled on a stub shaft 189 carried by the frame.

The conveyor 181 is driven by the shaft 9,.thewheel 57, the pitman 188, the pawl 186, the ratchet wheel 187 and' the drum 1'83.

" General"opemtiom The statement of operation may be abbreviated to a resume in v-iewof what has-been stated hereinbefore in connection with the working of the several constituent mechanisms. I

The conveyo1=16 ofFlgure 4 carries the prints into the machine: The innermostiprint 44 ofF-igure 4 is held by thegrips 24 of Fig ure 8* whilst the said print. is being carried downwardly'under: the ram 27. The gripsor a ws58-61 of Figure 21 carry thepaper under theprint, and a length of paper is cut off by the shear'76. The ram 27 moves the print 12 rise and.fashion the flap 126. The rollers 141 move to the left into the position of Figure 14 and turn over the second end flap 137.

The rotor 93 turns, and the end 153 of the wrapping paper is flattened down by the roller 154. As the rotor turns, it carries the print past the rollers 161, and the third end flaps 157 are turned over The ejector 17 7 takes the print 1200f Figure 20 out of the rotor 93, the fourth end flaps 162 being-closeddown, and the print being advanced into the position shown at 17 9 in Figure 20. As one printpasses into the chute 178, it crowds out a preceding print upon the conveyor 181 of Figure 2, and the conveyor moves the wrapped print along I toward the rear end B of the machine.

' vancement to the conveyor, a grlp mounted on the shaft and releasably engaging the article to be wrapped whilst the conveyor is moving the article into position between the ram and the carrier, the clutch and the grip embodying enterengaging parts which advance and retract the grip as the shaft is oscillated, and means for interposing a wrapper between the article to be wrapped and the carrier.

2. In a wrapping device, a rototable carrier for the article to be wrapped, the carrier having a circumferential track, a plunger mounted for straight-line sliding movement,

a lever pivotally mounted intermediate its ends on the plunger, one end of the lever cooperating with the track, a folder at the opposite end of the lever, and means'for imparting movement to the plunger to cause the lever to tilt with the track as afulcrum, and bring the folder into operative relation to the end of the carrier.

3. In a wrapping machine, a shaft supported for rotation, a sleeve rotatable on the shaft, an endless conveyor driven by the sleeve, aratchet on the end of the sleeve, a grip so placed as to engage an article on the conveyor, the grip being slidable longitudinally of the shaft and including a part engaged with the ratchet, a movable carrier, folding mechanism cooperating with the carrier, yieldable means for advancing the grip to cause the grip to engage an article on the conveyor, means for rotating the shaft in one direction to cause said part of the grlp to cooperate with the ratchet in turning the cause said part of the grip to slide overthe ratchet and retract'thelgripfor engagement with another article on'the conveyor under the impulse of said yieldable means; c

In a wrapping device,a movable car-- rier for the article to bewrapped, means for wrapping +he article in thecarrier, an ejector,means for moving the carriertobring the article into the path of the ejector, and mechanism for opcrating the ejector, said mechanism comprising a fixed track, a slide mounted to reciprocate on the track and supporting the ejector, a bell crank lever and a fulcrum therefor, one arm of the bell crank lever being pivotally connected to the slide, a first shaft supported for rocking movement and having arms, a connection between one arm of the first shaft and the other arm of the bell crank lever, a second shaft 7 supported'for rotation, means-for rotating the second shaft, and means for connecting I the second shaft operatively with the other arm of the first shaft.

5. Ina wrapping device, a rotatable carrier for the article'to be'wrapped, a freely rotatable folder rot'atable'by contact with the end of the carrier and movable upon the end of the carrier in a direction substantially at right angles to its aXis of rotation,

means for moving the folder in a direction substantially at right angles to its axis of rotation, upon the end of the carrier, a free- 1y rotatable folder cooperating with the end of the carrier, and means for rotating the carrier with respect to the last-specified folder, thereby to render the last-specified folder active, and to cause it to rotate.

6. In a wrapping device, a rotatable carrier for the article to be wrapped, a slide mounted for straight-line movement at the end of the carrier in a direction transverse to the axis of rotation of the carrier, means for reciprocating the slide in the direction of its length, an arm pivoted to the slide, a

roller journaled on the arm, and spring means for actuating the arm to cause the roller to bear on the end of the carrier. c 7. In a wrapping device, a frame, a rotatable carrier for the article to be wrapped, and journaled on the frame to turn about an axis, levers fulcrumed at their outer ends diatetheir ends and constituting means for malntaining the folders engaged with the ends of the carrier, with an equalized pressure.

8. In a wrapping machine, a frame, a rotatable carrier journaled 0n the frame, 111

fixed track extended across the frame from side to side in parallel relation; to the carrier, and across the carrier from oneendof the carrier to another, a slide mounted to reciprocate longitudinally of the track and including a ram movable longitudinally of the carrier, a long lever fulcrumed at a point remote from the slide, the lever being mounted to swing in a substantially horizontal plane, parallel to the track, and means for pivotally connecting the lever at one end to the slide, the track supporting said end of the lever and supporting the slide at any point between the ends of the carrier where the ram is operating. V

9. In a wrapping device, a rotatable carrier having circumferentially spaced seats for an article to be wrapped, mechanism for depositing a wrapper and an article to be wrapped in one of said seats, means for folding the wrapper about the article in the seat, and: means yieldably engaged directly with the carrier, and movable to engage directly in another of said seats for an article, to hold the carrier against rotation and to position the first-specified seat for cooperation with said mechanism. 7 V

In testimony that I claim the foregoing as my own, I have hereunto set my hand.
