Referring to the drawings the reference numeral 5 indicates a main frame upon which is journaled the main transverse driving shaft 4 having fast and loose pulleys 3 and 2 respectively positioned thereon. A drivin belt 1 (shown in Fig. 4) extending aroun loose pulley 2 may be shifted to fast pulley 3 to drive the machine. The main 5 driving shaft 4 extends transversely through the main frame 5, and at its opposite end portion carries a bevel pinion 6 and a sprocket wheel 7, the latter being on the outer end of the shaft. The sprocket wheel 7 has a sprocket chain 8 extending therearound and also around a sprocket wheel 9 which is journaled on a shaft 10 also extending transversely `of the frame 5. The sprocket wheel 9 is provided with a clutch l5 hub face 11 positioned to engage a complementary clutch member mounted fast on the shaft 10 to drive said shaft. A dependin rock arm 12 controls the reciprocation o the clutch 11 to engaging and dis- 20 engaging positions. A chain ti htener guide 13 is provided for the sproc et chain as shown in Fig. 4.

Mac'n dri/ve 25 The bevel pinion 6 is in mesh with a bevel pinion 14 loosely mounted on a rearwardly and downwardly extending shaft 15 journaled on one side of the main frame 5. Clutch elements 16 are formed in part on the 30 pinion 14 and controlled by a depending arm 17 for drivingly connecting the said pinion to the shaft 15. The shaft 10, near the clutch 11, 1s provided with a pinion 18 which is in mesh with an intermediate gear 19, and sald gear 19 is in turn in mesh witha gear 20. Said gear 20 is mounted on one end of a transverse shaft 21 extending transversely through the main-frame 5, and on the opposite side of the frame carries a sprocket wheel 22 as shown in Figs. 4 and 5.

Convey/cr belt The downwardly and rearwardly extending shaft 15 journaled in main frame bearings 23 and 24, has a bevel p1n1on 25 mounted on its lower end which is in mesh with bevel pinion 26 mounted on shaft .27. Said shaft 27 extends through and Vis journaled 50 transversely in the frame 5 and carries a long roller 28 as a main driving means for a conveyer belt 29. The conveyer belt passes around the main driving roller 28 and .extends downwardly and around an idler gulde roller 30 carried by a transverse shaft 31, thence around a belt tightener roller 32 carried by an adjustable arm 3 3 swung downwardly from the upper port1on of the main frame 5. From this point the belt conveyer 29 extends upwardly and around a terminal roller 34 carried by brackets 35 mounted on the main frame'and extending towards the yfeed table 36, as clearly shown in Figs. 1, 2, 4 and 5. 4From theV terminal roller 34 the g5 belt 29 passes over 4the way 38 having rollers Olntck control Adjacent the feed table 36 is located a I handle 44 connected to the bar 45 which is carried by guides 46 and 47 mounted on the main frame 5. The bar 45 has pins 48 and 49 coacting with the arms 12 and pins 50 and 51, and also with the arm 17 so that by thrusting the arm 44 away from the table 36, the operator can simultaneously shift the arms 12 and 17, and thereby disconnect the main driving shaft 4 from driving connection with the parts of the machine actuated by the sprocket chain 8 and the shaft 15. The reverse reciprocation of the bar 45 serves to simultaneously connect these parts for operating the machine.

Fcecl control The transverse shaft 21 adjacent oneend portion is provided with a cam 52, as shown in Figs. 4 and 19, for thrusting the bar 53 towards the table 36 and against the resistance of the spring 54 surrounding said bar. The thrust movement of the bar 53 is against the depending arm 55 of a lever fulcrumed on a shaft 56 and having upper arms 57 which carry a pair of feed rollers 58, so that in the timed relation of the rotation of the shaft 21, the feed rollers 58 are swung upwardly to clear the conveyer belt 29 which is traveling over the roller 34 adjacent the table 36. The lever arms 55 and 57 carry a nger 59 movable to turn a rock bar 60, and swing stop members 61 and 62 (Figs. 4 and 5) mounted on said bar 60, downwardly against the resistance of torsion spring 62.

The i blank The blank used in forming the box is shown in Fig. 8, and comprises a sheet of material having longitudinal parallel lines of spaced scorings 63 and 64, short longitudinal lines of scorings 65 and 66, and spaced transverse scorings 67, 68, 69 and 70. The blank has cut in portions 72 from the intersections of scorings 67 and 69 with the.scorings- 63 and 64. The scorings 63, 64 and 67 form one side 73 of the box and said side is provided with .fractional end portions 74 extending therefrom. The scorings 63 and 64 between the scorings 67 and 69 form the box bottom 75 and said bottom portion is provided with end portions 76 extending beyond the scorings 63 and 64.

The scorings 63 and 64, between the scorings 69 and 70, form a box side 77 opposite to box side 73 and is formedwith fractional end extensions 78 which coact with the ends l74. Extensions 79 from the ends 74 are and 71 form the top portion 80 of the box and said top portion is provided with tuckin end flaps 81, and a tuck-in terminal tongue 82.

Blank guidance The boXf blank in flat condition with its scoring groove on its lower side is placed on the table 36 in position to have its tongue 82 coact with the stop 62, and with the edge of the flap 81 resting against the stop 61 as the pair of receiving rolls 58 are raised. This movement positions the end portions of the box blank upon the conveyer belt 29 adjacent the roller 34 to prevent travel of said blank on said belt due to the stops 61 and 62. As the shaft 21 is continuously rotated, the cam 52 is effective in permitting the spring 54 to swing the pair of receiving rollers 58 downwardly to yieldingly engage the box blank resting on the belt. Simultaneously with this engagement, the stops 61 and 62 are moved out of the path of travel of the engaged box blank, and the blank will be immediately moved by said belt, thus providing for the blanks being intermittently fed into the machine in a timed and registered sequence. The box blank is moved by the belt in the region of the guide 38 and supporting rollers 39 therefor.

During this travel, definite guidance of the box blank is provided by mounting over the belt 29, justifier rolls 83 either singly or mounted in pairs. Said rolls are carried by and journaled in depending bell crank arms 84 mounted on fulcrum pins 85 connected to the frame 5, andjthe horizontally extending arm portions 86 of saidbell cranks are yieldingly engaged by pins 87 as shown in Fig. 10. Springs 88 yieldingly hold the pins in engagement with the arm portions 86 and the tension of said springs may be adjusted by screws 89. The last mentioned parts forming guide roll assemblies are mounted in housings 90 carried by bars 91. This construction provides for adjusting the tension of the rollers 83 upon the blanks carried by the belt 29 to more firmly hold the traveling blanks in position on said belt.

First end fold 98 for thrusting said plungers upward as the ends 76 of the blanks pass thereover. This movement of the parts folds the end portions 76 on the score lines 63 and 64. The end portions 76 as thus folded upwardly during their travel, pass under adjustable curved guide means 99 to further direct the said end-portions 76, during their travel, into completely folded down position against the inner side of the bottom portion 75 of the blank. The partly folded blank now travels with the belt 29 to the roller 40.

Mid-bottom transverse fold The shaft 10 has mounted thereon adjacent the inner sides of the frame 5, pinions 100 which are in mesh with pinions 101 mounted on an adjacent parallel shaft 102 which carries the roller 40 and the milled adjustable roller sections 103. Said milled rollers are staggered with relation to milled roller sections 104 mounted on the shaft 10.

The shaft 102 is journaled at its opposite ends in bearing blocks 105 slidably 'positioned in bearings 107 mounted on the main frame 5, and yieldingly engaged by springs 106 positioned in the bearings 107 to force the shaft 102 towards the shaft 10.

The partly folded blank, having its ends 76 folded towards each other, passes over the roller 40, and upon engaging the milled rollers 103 is forced olf the belt 29 and forwardly upon guides 108 and will be moved to the adjustable stops 109.

The portion of the shaft 21 projecting outwardly from one side of the main frame 5 and adjacent the sprocket wheel 22 earries a cam 110 which is engaged by a roller 111 carried by an arm 112, and said arm is adjustably mounted on a rock shaft 113 by set screws 114. Folder arms 115 are also mounted on the rock shaft 113, and likewise arm 116 which is pivotally connected to a downwardly extending rod 117. A coiled spring 117 surrounds the lower portion of the rod and bears against the frame and the rod and indirectly yieldingly holds the roller 111 in engagement with the cam 110. As the shorter radius of the cam 110 is reached by the roller 111, the folder arm 115, which has a toothed or plate portion 118 at its free end, will be forced downwardly by the said cam 110, and the toothed or plate portion 118 will strike downwardly on the score line 68 of the blank. This move-v ment will fold the inwardly folded end portions 76 as well as the bottom portion 75 After the transverse folding operation the l partly folded blank is redelivered to the conveyer belt 29 by passing between the milled rollers 103 and 104 on the relatively Adhesive apply/ng device Adjacent the main yshaft 4 and parallel therewith is journaled a bar or shaft 119 (Fig. 13) provided with spring guide arms 121 adjustably connected thereto by set screws 120. These yielding guide arms 121 serve to direct the blank extensions 79 from the end portions 74 upwardly against the adhesive applying rollers 122 which are i mounted on the main drive shaft 4. Said rollers 122 bear against and close outlet openings 123 formed in adhesive carrying reservoir 124 carried by the main frame 5. Preferably the adhesive material used is in the form of a glue which may be applied cold.

The adhesive reservoir 124 has an angularly shaped hinged cover 125 through which the stem 126 of a packer head or piston extends, to permit thrusting the head downwardly to force the adhesive material towards the outlet opening and the adhesive applying roller 122. Extending in a plane parallel t0 the bar or shaft 119 are spaced mounting strips 128 to form a groove o r slot for adjustably receiving the lower ribbed portion of the reservoirs 124. Bolts 129 extending through cross bars 130 and the slot and threaded into the bottom portions of guide tracks 131 adjustably hold the guide tracks in position. The guide tracks extend longitudinally of the frame 5. The reservoir 124 is formed with flanges 132 which coact with. the guide tracks in permitting the reservoirs to be adjusted toward and away from the adhesive applying rollers 122.

As the shaft 4 rotates continuously during the operation of the machine, even though the conveyer belt be idle, the adhesive material in the reservoirs will not bind the rollers to the reservoirs during said operation.

-the machine applying the adhesive material to the partly formed blank. I mercepter A sprocket chain 133 extends around the sprocket wheel 22 and downwardly and forwardly therefrom and also around sprocket wheel 134 which is mounted on the shaft 135. Adjacent the sprocket wheel 134 and on the same shaft 135 is mounted another sprocket wheel 136 around which extends a sprocket chain 137, said sprocket chain also extending around sprocket wheel 138 mounted on shaft 139 and thence around sprocket wheel 140 mounted on shaft 141, as shown in Fig. 5.

The shaft 139 is provided with a cam 142 for reciprocating bar 143 which is pivotally connected at its opposite end to a short arm 144 mounted on a shaft 145 and has an intercepter 146 extending downwardly therefrom. The driving sequence is so arranged that the intercepter may hold the first longitudinal and additional transversely folded blanks against travel with the conveyer belt notwithstanding the blanks are resting on the belt. At this period of holding the extensions 79 are coated with the adhesive and then flexed over and upon the portions 78 and flattenedv thereagainst to effect sealing. The holding action of the intercepter is for a brief interval of time for maintaining registry in the flexing and flattening in the sealing operation.

Sealing The sprocket chain 137 in driving the shaft 141 brings about the flexing, flattening and the sealing completing operation. Said shaft 141 is provided with a bevel gear 147 (Fig. 17) which is in mesh with a bevel pinion 148 mounted on shaft 149 which also carries a pair of cams 150 and 151. These cams yare arranged in rights and lefts so that bars 152 may be simultaneously oppositel reciprocated. The bar 152 carries a ro ler 153 which coacts with the cam 150, and a roller` 154 which coacts with cam 151. The bar 152 may pass through an adjustable xed guide member 155. This guide member 155 has a bearing 156 for an angled lever member having a slotted arm 157 which coacts with a pin 158 carried by a block 159 adjustably held by collars 160 mounted on the bar 152. Said collars 160 have rack jaws 161 which extend into the collar way 162. Pins 163 extending upwardly through the collars may be manually operable to shift the rack jaws 161 (Fig. 18) in the ways 162 when the collars 160 are released from said bar 152 by unscrewing set screw 164.

The rack 161 coacts with rack portions 165 on the bar 152 for maintaining the collars 160 in their desired adjusted positions. Loosely mounted on the bar 152 and shiftable toward and away from the collars 160 is mounted a carrier 166 having a guideway 167 into which extends a vertically reciprocable member 168 carrying a roller 169. The member 168 has an overhanging portion or projection 170. As the cam 160 coacts with the roller 163 to pull the bar 152 away from the guide 155, the pin 158 serves to rock the arm 157 on the fulcrum 156 (Figs. 15, 16 and 17) and cause the arm 171 to ride beneath the roller 169 and lift the member 168 in the guide 167 into engagement with the overhanging portion 17 O and cause said portion to rise against the lower side of the blank extension opposite to that provided with the adhesive coating.

The cverhanging arm 172 extending from the carrier 166 terminates in close proximity tothe folded blank end portions 78 s o that it will hold down the blank on the guide 42, and the upward movement of the overhanging portion 17 0 will cause the flexing of the extension 79 on the score lines 65 and 66. The flexing movement is effected during the movement -of the carrier 166 towards the shaft 149, when the intermediate collar 160 engages bearing 166 (Fig.` 15), but the rate of upward movement of the overhanging portion 170 is such as to cause the flexing of the blank extensions 79 at the score lines. Furthermore, as the member 170 rises, the free end of the arm 171 clears the roller 169 so that the member 168 can moveV downwardly and engage the flexed over blank extensions 79 and flatten such adhesive carn rying blank extensions against opposite blank portions for sealin the parts together. This flexing and attening occurs while the intercepter 146 is holding the twice folded blank for the third folding or second longitudinal folding operation.

The cams 150 and 151 rotate continuously and as the member 170 moves downwardly upon the extensions as unfolded for the flattening and sealin operation, there is a slight pause, and t en the recover travel occurs in the shifting of the carrier 166 back to starting position for a repetition of this cycle of operation as actuated by the inner collar 160.

Flattem'ng of rollers 173 beyond the roller 28. The

final roller 176 has a conveyer belt 177 over Which the sealed thrice folded blank, as a knock-down box, may pass for further flattening opening operation under gravity idler rollers 178. After passing the rollers 178 the folder blanks are then discharged upon the kicker 179 (Figs. 1 and 4).

Discharge grouping Standards or legs 183 (Figs. 1 and 14) carry parallel bars\184, and an abutment 185 loaded by friction weights 186 to ride upright along said parallel'bars 184. The thrice folded blank upon the bottom portion is folded on itself short of the end portions 74v and has been sealed with the end portions 78 by means of the member 168. These articles are thrust by the kicker 179 to have the folded bottom portion 75 of the formed knock-down box travel between the pair of rails 184 as the formed knock-down box assembly is now on edge and in a vertical position, so that its projecting edges end portions 74 and 78 will ride on the bars or rails 184.

The yieldable mounting 180 for the kicker 179 permits yieldable thrusting of the successively formed knock-down boxes into position along the pair of rails 184 for packing said boxes on edge on said receiver.

The resistance to such packing is yieldable as the abutment gradually slides along the rails 184.

Adjustments are provided for the folders and guides to permit the making of boxes and styles of dierent sizes within a considerable range. There is therefore in the disclosure of this invention, a machine which has a wide range of utility for the rapid production of symmetrical knock-down boxes or containers.

The stops, guides and sealing folders are adjustable along the main frame 5, and also the belt 29. Set screws 187 may adjust the folder member 155 on track 188. Set screws 189 permit guide housings 90 to be adjusted along the bars 91. Set screws 191 permit adjustment of the milled rollers 103 and 104 to insure folding and may partially overlap in their staggering.

The machine may be operated at a high production rate with` unskilled labor in pro# ducing a product of high grade. The machine does not require extreme care when set up for operation and will handle in addition to different sizes of boxes, dierent thicknesses of stock for said boxes.

From the foregoing description it will be .seen that the machine is of very simple construction for the Work it accomplishes and is well adapted for the purpose described.
