The block 10 is preferably made of sheet metal and is substantially rectangular, but its shape and dimensions may vary with the shape and dimensions ofthe cartons used. A lian e 11 at the bottom of the block is rivete or otherwise secured to a plate l2, which is secured to the chain 6 by the angle plates 13,.

(Fg- 4J orizontally grooved tracks 14, extending the entire length of the machine,are arranged to receive the side margins of the.

plates`12 and to carry them during their travel over the machine in one direction.

Each of the male blocks 10 is provided with a leaf spring 15 for retainin a carton on the block when in` an inverte position,

4which will hereinafter be made clear. Each of the blocks 10 is also provided with a means vfor delivering the cartons, which means comprises a block 16, an integral plate 17 havingv beveled, faces A17, arranged to slide in the slot 18 in the male block 10, and a hook 19 adapted to be operated by a means A folder 20 isiixed to the frame of the 1o prises a'singlepiece of sheet metal substanthe blocks 10, and

-scri tiallytn arin shape, having its forward end rounde and slilghtly' beveled to' prevent the cartonbeing he d thereby. y

A glue box- 26 is rigidl secured to the machlne frame over the pat of travel of the Carton carriers and desi ed to supply a quantity of glue to a rol er 27 having two surfaces 28-29 separated -by an annular W groove 80.

`of the second folder,

`-urper end of the shaft, anda A second folding ap aratus fixed 011 the frame 1, immediately fbllowing the gluing device, comprises a rock-shaft 31 in the bearers 32, an arm 33 at the upper end of the shaft, and a shoe 34 adapte to engage and fold inwardly and downwardly a si e flap of the carton. Fixedto the shaft 31 at its lower end vis an arm 35, which is enlgaged by a projection 36 on the bottom of t e plate 12.

A third folding apparatus, opposite the Second folder, acts on the other side-flap of the carton, immediately following the action and comprises a rockshaft 37 in the bearers 38, an arm 39 at the shoe 40 adaptto engage and fold inwardly and downwardly the second side-Hap of the carton. Fixed to the shaft at its lower end is an arm 41, which is engaged 42 on the u per face, of the plate-12. A second) series of inafter termed femaleblocks 43, are carried by the chain 6 and spaced apart thereon at regular intervals, one between each air of the male blocks 10. The female bloc 43 is preferably made of sheet metal and is composed of the upright walls 44-45, of substantially vthe same height as the male blocklO.

A bottom piece 46, of va height corresponding to the il ps on the carton, is secured to a plate 47 Wlthin the walls 44-45, and the plate 47 is secured to the chain 6 by the angle plates 48. The plate 47 is embraced tween and carried by the ooved tracks 14.

An arm 50 is hinged to t female block and arran ed to be engaged at a given point by the xed arm 51 to discharge a carton, said arm 50 bein operated in one direction bythe s ring 52 xed at its one endto the wall 45 o? the carton carrier,

. and its other end to the free end ofthe arm 50.

An endless. conveyer 53, embracing the folder, hereinafter deby a projection carton carriers, here-v e wall 44 of the Elulleys 5 4. and 65, is 'to travel in a parallel with and in t e same direction as the chain 6, motion being imparted theretothrough the belt 55, and pulley 55" on the shaft 8, to a point 1n front of the lirst folding device, at whichl oint is located an apparatus for removing om the conveyer 53 the cartons, one at a time,'and placlng them within the female blocks. f This a Eg-atus comprises a rock-shaft 56 in tlie l ril 57 ,han extension 58 of which is enge y t e rojection 59 on the late 47 ogf the female block. p

An arm 60 is pivoted to the machine frame and arranged to actuate fa plunger 61 throu h the medium of the link 62 connected w1th t e rock-shaft 56, the plun er being returnedto its normal position by 51e spring 63.

At the forward end of the machme is an apparatus for discharging the cartons closed and glued at their lbottom ends, and comrising anl arm 64 pivotally hung in the rame 1, (Fig. 12.) ada ted to be engaged by the projection 59l on t e female block, a rod 65 supported in the bearing 66, and a link 67 connecting said arm 64 and rod 65. The free end of the rod 65 is designed to engage a hook 19, which elevates the block 16, thus discharging a carton from the block 10.

To hold the end flaps downwardly for a portion of their travel is a strip 68 fixed at its one end to the spreader 25, and its rear end toa hanger 69.

To lnsure a perfect sealing of the flaps after they have passed through the ming apparatus, a series of weighte rollers 70-70 resting in the notches 7l -bear on the endless belt 72 which firmly holds the mmed flaps for a given length of time uring their. travel over the machine, the said belt embracingpulleys 73-74 mounted in the bearings 7 5-7 6, motion being imparted thereto through the cross belt 7 7 ernbracing the pulley 78 on the shaft 79'which carries the pulley 73 and the pulley 8 0 on the shaft 3. v

ln the practical operation of the machine,

cart-ons, with all of their flaps extended outwardly, are placed upon the male blocks 10 on the endless conveyer 6 and carried rearwardly by said carrier to a oint where the combined folder and spreadier engages the first end-flap and the two side-flaps, which folder and spreader acts to fold rearwardly the first end-.fla and fold outwardly the two side-flaps, the older 20 acting upon the rear end-flap andr placing its^ forward mar in under the combined folder and sprea er. The side-flaps of the carton, thus held outwardl are passed under the surfaces 28-29 and t en to the second and third folders, which folders engage and fold the side-flaps which have just been gummed inwardly, and' which flaps are then carried under the beltY roo perfect sealing. he cartons are then carried underneath themachine and held from dropping fromV the blocks l() by s'prings 15, to t e vstarting point where the discharging rod-65 engages the honkv 19 and block` 16,

and thus y discharges the carton sealed at 'one end. The cartonsl are then filled with y, ing

merchandise and placed withtheir sealed ends downwardly on a conveyer 53, which conveyer carries them to a oint where the plunger 61 vis actuated to -p ace the cartons within the walls of the female block.` The cartons are then carried by the yfemale blocks and acted u-pon'by the folding and gluing devices'in the same manner as when sealing their other ends.v The lled and Vcompleted cartons are then carried to a point where the ixed arm 51 engages the pivoted arm 50 to the machine.
