In the embodiment of the invention illustrated in the drawings the operative mechanism of the apparatus is mounted on a table 29, and said mechanism is actuated from a drive shaft S journalled in standards s mounted upon the table 29, the drive shaft being operated from a motor M by a chain tpassing around a sprocket wheel a on the motor shaft and a sprocket wheel is fixed to a shaft 1 having a worm and worm wheel driving connection n with the driving shaft S.

Blanks B (Figures 3 and 17) from which the I receptacle bodies are formed are fed or delivered from a pile on a suitable support it onto a shelf T with an edge of the blank in register with a gauge 1 mounted upon the shelf. The shelf is mounted to extend in a horizontal plane upon standards 2, 3 fixed upon the table 29 below a mandrel or horn 4 and around which mandrel the blank delivered to the shelf is wrapped in forming the receptacle body. The blanks are fed to the shelf T by suction means as illustrated and described in my afore-mentioned co-pending application Serial No. 394,315, and it is believed it is not necessary to describe the structure and operation of said means in the present application.

When the blank B has been positioned on the shelf T by the suction means, means is operated to lift said blank from the shelf T to the mandrel 4, as fully set forth in my co-pending application, and the raised blank is wrapped around the mandrel by a rectangular open head 26 reciprocated toward and away from the mandrel in a guide member 28 extended through an openin in the table 29 and having a flange 28' whereby it is supported upon the table 29. The head 26 has a pair of ears 31 extending outwardly from opposite sides and between which ears a pair of arms 32 are pivotally supported, (Figure 1) and said arms extending upward and adapted to be urged in a direction toward each other. Flaps 35 are pivotally carried, as at 36, by the arms 32, said flaps being of curved form in cross section to conform with the contour of the mandrel. As said arms are moved upward by head 26 the leading longitudinal edge of the flaps engage the blank at opposite sides of the mandrel, and the continued upward movement of the head will move the flaps to encircle the mandrel and receptacle blank around the mandrel. The receptacle blank is of a width so that one longitudinal marginal portion may be lapped over the other marginal portion on the mandrel, and to facilitate the overlapping of one marginal portion over the other marginal portion the blank wrapping movement of one flap is retarded by rod 37, as fully disclosed and described by co-pending application Serial No. 394,315.

The mandrel 4 comprises a truncated conical block, fixed by a reduced portion 92 at the larger end to the standard 3 for the blank supporting table T.

The blank Wrapped around the mandrel 4 is secured and sealed at the overlapped marginal portions to form the receptacle body by a strip applied to the receptacle blank over the marginal portions, by a ram 86 movable toward and away from the mandrel, the sealing strip comprising a fed portion severed from a web W of suitable material, such as paper, having an adhesive surface, which surface is moistened and rendered adhesive as the web is fed. The web is fed from a roll (not shown) rotatably supported by a pair of parallel standards 95 fixed to and extending upward from a crosshead 96 fixed upon standards 97 on the table 29.

The ram 86 is in the form of a lever of hollow structure pivotally supported intermediate its ends, Figures 2 and 3, in standards 13 by trunnions 200 extended laterally from opposite sides thereof, the ram being rocked to move an anvil 120' carried by the end of the ram extended over the mandrel into and out of engagement with mandrel by a roller 201 carried by a bracket 202 adjustably connected to the opposite end of the ram lever and engaging a cam groove in a disk 203 fixed to shaft S, the ram being guided in its movement and held against lateral distortion due to the connection of the ram with its actuating cam by a block carried by and extending laterally from opposite sides of an arm 13" extended from one of the standards. 13 into the hollow portion of the ram in a direction toward the anvil carrying end of the ram and engaging arcuate recesses in the opposite inner surfaces of the wall of the ram, as at 204. The movement of the anvil carrying end of the ram toward the mandrel may be varied by adjusting the carrying bracket 202 for the cam following roller.

The web feeding means comprises a pair of grippers mounted in the rear of the large end of the mandrel and in line therewith and reciprocatory toward and away from the mandrel, the grippers being operative to grip and positively feed a predetermined length of the web as. they are moved in a direction toward the mandrel, and to release the web at the termination of such movement and during the return movement thereof. This gripping means, as illustrated in Figures 1, 2, 3, 5, 6 and 18, comprises a pair of levers 98, 98' pivotally mounted intermediate the ends to have movement on parallel axes on a reciprocatory carriage in the form of a slide 99. At one end the levers are extended laterally at substantially a right angle and in parallel relation to each other with the extremities extended toward each other, as shown at 100, 100, the end 100 of lever 98 being substantially flat while the end 100 of lever 98' a point or line contact with the fiat end of the other lever, and to constitute the web gripping surfaces of the levers. At the opposite end the levers are connected by

toggle links

101, 101 by pivotally mounting the same on pins in bifurcations at said ends of the levers, and the links are pivotallyconnected by the engagement of the link 101 in the bifurcated end of link 101', as at 102, and the extremities 100, 100' are normally yieldingly urged in a direction away from each other by a spring 103 connected to the levers adjacent the toggle links connecting the ends of the levers. The levers are connected to transmit the movement of one lever to the other by a pin and slot connection 104 between

arms

105, 105 extended laterally from the levers in line with their pivotal supports. To limit the spreading movement of the gripping end of the levers by the spring the one toggle link 101 at the pivotal connection with the other toggle link is increased in width and has a corner at the juncture of one side edge with the end. bevelled, as at 106, whereis beveled to have I by when the toggle is broken and the toggle connected ends. of the levers are moved toward each other by the spring 103 said bevelled portion will engage with the connecting portion of the bifurcation legs of link 101, as shown in dotted lines in Figure 5. The movement of the gripping levers to web gripping and releasing positions is controlled by a latch 10'! mounted on the pivotal connection 102 of the toggle links and the pivotal connection of toggle link 101 with the gripper lever 98, as clearly shown in Figures 5 and 6, said latch 107 carrying a roller 108 on a stud extended laterally therefrom and opposite to the gripper levers. The gripper carrier 99 comprises a block having parallel recesses therein for mounting on a pair of rails 109 and retained thereon by a plate 99' releasably secured to the block, the rails being mounted at one end upon a standard 97 and at the opposite end upon the supporting standard 3.

The gripper carrier 99 is reciprocated from the driving shaft S through a shaft Sb' (Figures 2,

3, 4, 17) operatively connected with the drive shaft through bevel gearing 110 (Figure 4) and the gripper carrier is operatively connected with said shaft Sb by a roller carried by a lever 111' engaging a cam groove in a disk F fixed on the shaft. The lever is pivotally supported upon and extends upward from the table 29 and is operatively connected with the gripper carrier 99 through a link connection 112' between said lever and a lever 113 loosely hung on a shaft 114 in a standard 115 fixed upon the table (Figure 1), said lever 113 having a link connection 116 with the gripper carrier. The connection between link 112'and lever 113' is intermediate the ends of said lever and is-adjustable, as shown at 113' in Figure 4, whereby to vary the movement of the lever 113 and thereby the travel of the gripper carrier 99 and length of the web fed.

To actuate the toggle link operating latch 107 as the gripper carrier reaches the termination of its web feeding movement, the latch roller 108 engages a stop 11'! adjustably mounted on a slide rod 118 slidably mounted in a standard 97 on which the supporting rails 109 for the gripper carrier are mounted (Figure 1) and a bracket 119 fixed on rails 109. As the latch roller 108 engages said stop the slide rod 118 is moved in a direction reverse to the web feeding movement of the gripper carrier 99 thereby moving the latch to the position shown in dotted line in Figure 5 with the toggle links 101, 101 moved to exhausted position and permitting the gripper jaws to be moved to the dotted line position by spring 103 and releasing the jaws from the web. This movement is imparted to the stop carrying slide rod 118 by a roller carried by a link 120 engaging a cam groove in a disk G on shaft Sb, the link being bifurcated and straddling said shaft. The l nk 120 is connected with an arm 121 fixed to a shaft 122 rotatably mounted in a standard 123 and a bearing member fixed to one of the standards 97, said shaft being connected with the stop carrying slide by an arm 124 fixed to said shaft having a link connection 125 with the slide rod 118. It will be obvious that by adjusting the stop 11'? on the slide 118 the time at which the grippers are released from the web may be varied and thus effecting variations in the length of web fed.

To move the gripper levers 98, 98 to web'gripping position at the end of the return movement of the carrier 99 and before the commencement of the web feeding movement of the same, a second stop 126 is mounted on the slide 118 for engagement of the latch roller 108 to actuate the latch 107 to move the toggle links 101, 101' to full l'ne position, as shown in Figure 5. The stop 126 is pivotally mounted on the slide rod 118 at 127 whereby it may be adjusted to position out of the path of movement of the latch roller 108 with the result that no web gripping movement will be imparted to the gripper levers as the gripper carrier is rec'procated and no feeding of the websure to the marg'nal portions of the blankwrapped around the mandrel 4. The web is guided to said position by guiding means comprising a pair of sections, one section being fixed and embodying angle blocks 128 fixed to and spaced longitudnally of a pair of parallel and spaced rails 129 with the blocks suspended from therails in opposed pairs with the angle portion of the opposed blocks extended toward each other and the inner marginal portions of the rails overhanging said angle portion of the blocks, as

shown n Figure '7. The web is supported as it is fed by rollers 131 rotatably carried by the blocks,

the peripheral portion of the rollers being of V shape in cross section to have only a limited contact with the web. The rails 129 are supported at one end upon a plate 132 fixed upon angle brackets 133 mounted on the standards 97, the plate extending from the ends of and with the upper surface in a plane with the guide rails 129 to constitute a continuation thereof. The opposite ends of the rails are supported by an angle bracket 134 fixed to the bracket 119. By the spacing of the rails the gripping jaws of the feeding means are adapted to engage the web and move the same longitudinally of the ra ls. The other section 135 of the guiding means is pivotally connected at 136 to one end of the guide rails 129 and has a similar connection with a bracket 118 fixed to the end of the ram 86 to participate n the movement of the ram toward and away from the mandrel. The guide section 135 embodies one pair of roller carrying blocks 128 and a pair of guide rails 129 connected by cross pieces 137. From the guide section 135 the web is guided in interposed relaton -to the blank wrapped around the mandrel and the anvil 120' fixed in and projecting from the face of the ram (Figure 25) by a pair of parallel guide plates 121' arranged at opposite sides of the anvil and fixed to the reduced ends of pins 122' with the enlarged portions of the p'ns slidably engaging in bores 123 in the ram and normally urged outward by springs 124-. interposed between the ends of the pins and the bottom of the bores, with the shoulders formed by the reduced ends engaging perforations in plates 125' fixed to the face of the ram through which perforations the reduced ends of the pins are extended with the guide plates 121 extended beyond the face of the ram anvil.

As the ram 86 s moved toward the mandrel to apply the adhesive sealing strip to the marginal portions of the receptacle blank wrapped around the mandrel the fed portion of the adhesive web relative to the mandrel is severed by cutter mechanism (Figures 23, 24, 26 and 27), comprising a cutter 1'73 fixed to the end of the ram and extending'beyond the face of the ram anvil, said outter being of rectangular shape in cross section to arrange the same with a pair of cutting edges. This cutter co-operates with a tubular cutter in the form of a block 174 having anopening 175 therethrough to conform to the shape of the cutter 1'73 and the edges of the opposite walls at the entrance to said opening forming cutting edges with which the cutter 173 co-operates to sever the web. The cutter block 174 is secured in a recess 176 in the end of the mandrel relative to a fiat portion 177 of a portion reduced relative to the mandrel and enlarged relative to the reduced supporting end 92. By this arrangement the cutter instead of severing the web by a single shear cut a portion is severed from the web providing a clear edge at the severed edges or the web, the severed portion of the web being delivered to an opening 178 though the mandrel in line with the cutter block with which a chute 179.

is connected to direct the severed web portion to a suitable receiving receptacle therefor. As the ram moves toward the mandrel the forward end of the web guide section 135 is moved downward therewith to position the web relative to the cutter mechanism (Figure 23), and the end of the web projecting from the guide is engaged by a plunger 180 slidably mounted in a bore in bracket 118' and yieldingly urged outward by a spring 181 to guide the web to the cutter mechanism and strip the web from the cutter mechanism during the receding movement of the ram.

The adhesive surface of the web W is moistened as it is fed to render it viscous, and for this purpose a liquid carrying trough 138 is removably mounted upon the bottom of the plate 132, which plate served as a closure for the trough. To mount the trough on the plate gibs 139 (Figme 13) are fixed to the bottom of the plate at the opposite marginal portions, said gibs having an intermediate cut away portion 140. Longitudinally spaced cleats 141 are fixed to the sides of the trough adjacent the top to have sliding en'- gagernent with the gibs. To mount the trough on the plate the one cleat is positioned opposite the cut away portion 140 of the gibs' to position the top of the trough contiguous to the plate when the trough is moved longitudinally into sliding engagement with the gibs. The trough is releasably held against longitudinal displacement relative to an abutment 142 fixed to and extending downwardly from the plate and engaging the inside of the end wall of the trough by a yielding latch 143 carried by the plate engaging the end of the trough. The plate 132 has an opening 144 therein in relation to a recess 145 in said plate in line with the space between the rails 129, the web being retained and guides in said recess by a yielding presser 146 carried by a bracket 147 fixedto a standard 97. As the web passes over the opening 144 liquid is applied to the under adhesive surface by bristles 148 carried by a holder of resilient material 149 (Figures 10 and 16) mounted on a cross bar 150 in the trough and tensioned to normally assume a position with the bristles extended through the plate opening, the liquid being applied to the bristles by capillary attraction by an absorbent material 151 arranged on the holder contiguous to the bristle. The web is maintained in contact with the bristles by a gravity roller 152 (Figures 10 and 15) carried by an arm 153 pivotally mounted on a bracket 154 fixed to the standard 97 to which the presser carrying bracket 147 is fixed. The roller 152 engages and maintains the web in contact with the bristles by gravity. A pair of ears 155 are extended oppositely from the roller carrying arm messes 153, one to engage the plate 132 to limit the movement of the roller from the bristles and the other car to support the roller carrying arm from a guide rail 129 when the roller is moved out oi contact with the portion of the web superposed to the bristles. To prevent a momentary disengagemerit of the roller from the web and bristles by the sudden movement of the web during the commencement of the feeding thereof, a detent pin 156 is carried by the bracket 154 and yieldingly urged by a spring in a direction toward the roller carrying arm 153 to' engage an abutment 15'? fixed in and extending laterally from said arm. A tubular projection 158 is extended downward from the bottom of the trough for the removable connection of a heater, such as an electric heater (not shown) should it be desired to heat the liquid in the trough.

To supply liquid to and maintain it at a predetermined level in the trough 138 a substantially air tight liquid carrying receptacle 432 is carried by a bracket fixed to a standard 97, an outlet tube 433 leading from the bottom of the receptacle to the trough. A tube 434 opens to and extends into the trough to an extent below the desired liquid level in the trough and has a connection with the receptacle adjacent the top thereof and an air space above the liquid level in the receptacle. Should the liquid level in the trough fall below the end of the tube 434 air is admitted to the receptacle eflecting a flow of the liquid from the receptacle to the trough until it reaches a level to seal the end of the tube 434 in the trough when the fiow of the liquid is automatically shut off. Liquid is supplied to the receptacle through a tube 435 connected with the outlet tube. To control the delivery of liquid through the tube 435 to the receptacle instead of to the trough and flooding the same a. two-way valve is arranged in the connection of the supply tube with the outlet tube, indicated in a general way at 436. The valve is arranged toshut ofi the outlet tube from the trough when the supply tube is connected with the receptacle, and to shut ofi the supply tube from the receptacle and the outlet tube when the receptacle is connected other and are of progressively decreased thickness outward, as shown in Figure 20, are secured to the ends of the ejector rods with a reduced portion of the rods extended through the other angle portion and spaced from the angle portion 162, as at 163. The mandrel has diametrically opposite longitudinal recesses 164 therein and the ejector rods are spaced apart a distance to engage the portions 162 in the recesses 164 and so that the edge of a receptacle R will engage the space between the plate portion 162 and the extended ends 163 of the ejector rods 160. The ejector rods are carried by head 165 connected with a reciprocatory carrier by a stud forming a part of the head 165 extended through and slidable in a tubular portion 166 extended laterally from a slide block 167 of the carrier having recesses for slidable mounting on rails 168 fixed to a standard 97 and the bracket 3, and retained on the rails by a plate 169 secured to the block. The ejector rod carrier block 167 is reciprocated by an arm 182 fixed to a rock shaft 183 and having a link connection 184 with the carrier. The shaft 183 is rocked from a rocker arm 185 hung on shaft 114 having a link connection 186 with an arm 18''! fixed to shaft 183, the arm 185 being rocked by a roller on said arm engaging a cam groove in disk H fixed to shaft Sb. To impart an added increment of movement to the ejector rods 160 greater than that imparted thereto by its carrier a lever 189 is pivotally carried in a slotted portion extended downward from the tubular portion 166 of the carrier 167. The stud of the head 165 is of greater length than said tubular portion and one end of the lever 189 is pivoted to the end of said stud of head 165 extended from the tubular portion 166,. the opposite end of the lever extending below the carrier. As the carrier approaches the end of its ejecting movement the downward extending end of the lever 189 will engage an adjustable abutment 190 in bracket 3 rocking the lever and thereby imparting an added movement to the ejector rods. At'the end of the return movement of the ejector carrier 167 said extended end of the lever 189 engages an adjustable abutment 191 carried by an arm 192 "fixed. to one of the standards 97, and thereby imparting an additional return movement to the ejector rodsto position the plates 162 away from the mandrel and permit wrapping ofa blank around the mandrel.

The small end of the mandrel is free and unsupported during the ejecting of the formed. receptacle from the mandrel into the holder 226 and is adjustably supportedbythe standard 2 when the side sealing strip is being applied by the ram 86 to prevent springing of mandrel by the ram by providing an adjustable auxiliary support on the standard 2 (Figures 1, 17 and. 23), comprising an arm 205 rotatable in a recess of the standard 2 normally positioned as shown in full lines in Figure 1 and moved to mandrel supporting position shown in Figure 23 just prior to the ram engaging with the mandrel by a rod 206 pivotally connected to an arm 207 fixed to the mandrel supporting arm 205.
