BOX-MAKING MACHINE.

Specification of Letters Patent.

Patentedan. 8, 1918.

To all whom t may concern:

Be it known that I, CHARLES BURNHAM, a citizen of the United States, and a resident of Los Angeles, county of Los Angeles, and State of California, have invented certain new and useful Improvements in B0X- Making Machines, of which the following is` a full, clear, and exact description.

This invention relates more particularly to machinery for making berry or fruit baskets in which the body is made from veneer shocks and the said shocks folded and held together by a metal binding.r

lhere the baskets or boxes are yof a small size the metal binding may be and in the character of machine invented by me and such as disclosed in my Patent No. 1,119,343, granted December 1,1914, is made from a single narrow metal strip which is folded substantially rectangular ac,- cording to the shape of the box or basket and bound thereto, but where the boxes are of a large size as for example what are known as ve pound boxes, the machine to handle a single strip would be necessarily large and its feed slow for handling a strip long enough for such purposes. It is desirable therefore that in makino' this classv of bones or baskets that the binding be made of at least two pieces and so manipulated that. they may be simultaneously formed and bound to the box body as effectively as is done with a single strip for the small sized boxes.

One of the principal objects of the present invention is to provide a machine which is automatic; in action and which is adapted to take two narrow strips of binding meta-lf,l form them substantially U-shaped in cross'- section, and bend the strips transversely about a. former or anvil and clench the binding metal thus formed to the folded box body..

Another object of the invention is to; pro-A vide. simple and eiiicient. means whereby twol metal Strips may be benty about a former from opposite sidesthereof and.- the: bent .ends of the strip made. to overlap so as to. form substantially single binding or rim to adapt the same toA be'applied to a.; box body.

Other objects of the. invention are to pro-- vide. a simple and eliicient press for simu'l.` taneously folding the strips substantial-ly U-shaped lengthwise thereei; to provide simple and efficient means whereby two strips may be fed the same or different distances; to provide simple and eiiicient cutting means for the strips; and to provide ei'fectivel means for simultaneously folding the strips about an. anvil or former.

A. furthe-r object of the invention is to provide simple and eiiicient means for holding the bent strips about the anvil or former in position to permit a box body to be inserted therein and the binding itself clenched or bound to the box body.

A still further object of the invention is to provide an effectivemachine for making baskets or boxes which will have a large output and which is adapted to make baskets or boxes of various sizes. l

litli these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of' the description.

In the general construction of the machine shown in thepresent application, the metal binding is fed as two long strips from separate reels or otherwise or as a strip of double widthV which is cut lengthwiseto form two strips. The two strips are fed lengthwise ofthe machine on opposite sides thereof to a press which simultaneously bends the two strips lengthwise substantially U-shaped or V-shapedv in cross-section. In advance of the press is feeding means for the two strips which is adapted to force the strips forward a determined length and as the strips are fed forward, they are tilted so that one side assumes substantiaily a verticutting means, the bending means bends the 1 two strips toward each other on the sides of a substantially rectangular anvil or former corresponding to the shape of the box or basket to be made, and during such bending, moving two of the ends of one of the strips downward to permit the ends to pass under the ends of the other strip to underlap the same properly, the said strips as thus bent to form a rim being suitably supported on the anvil ready to receive the body or box-form. During the forming and bending of the binding, shocks arranged in different magazines are automatically removed' and placed in receivers of a rotary carrier so' as to lie crosswise of each other'. The shoolrs in this crosswise position are moved between the die and punch of punch ward into the binding or rim while still supported on the anvil or former. As soon as the boX body is properly inserted in the binding or rim, suitable clencher mechanism located adjacent. to the anvil and about the punch is made to clench the metal binding about the boX body after which the box body is removed in any suitable way and may be again placed in the carrier and conveyed from the machine or automatically ejected therefrom and stacked.

While the invention is shown as employed in connection with a machine of the automatic character described, it will 'be understood that many of the parts may be used in connection with a hand-operated machine or in a machine of av construction differing from that set forth herein.

The frame 10 of the machine may be of any suitable form and located at any convenient point thereon is a press 11. The press 11 has two narrow strips or ribbons 12 and 12EL of any suitable material usually tin or galvanized iron, which may be supported by or fed to the machine. in any convenient way, or the said strips may be unwound from spools or reels. rEhe press 11 is adapted to fold the two strips lengthwise thereof simultaneously substantially U- shaped or V-shaped in cross-section and comprises essentially two heads 13 and 13a with parts of which cooperate movable blades or members 14 and 14EL respectively, the latter being adjustably held by screws 15 or otherwise to a reciprocatory cross-head 16. The parts of the press located in the heads 13 and 13a are substantially the same and the parts coperating therewith mounted on the crosshead are likewise similarly constructed. The parts'mounted in the heads 13 and 13 each have a plurality of metal plates 17 and 17a of a bar-like form located on opposite sides of a center plate or bar 18 which latter is yieldingly held to move vertically. The plates orvmembers 17 17a and 18 as well as the members 14 and 14, are substantially identical and operate in the same manner as in my Patent No. 1,154,970, but as a single press. The cross-head 16 is: suitably guided toy move vertically in the frame 10 and at theA lower end thereof is connected to arms 19. One end of each arm 19 is pivoted, at 20, to a bracket 21 on the frame 10, the other end being provided with a trundle or roll 22 which is adapted to be operated by a cam 23. on the drive shaft 24. Asi the shaft 24 is rotated, they cams 23 will move the arms 19 and cross-head 16 causing the members 14 and 14a to be forced upward so. that both strips will be simultaneously folded lengthwise substantially U-shaped or J- shaped in cross-section as set forth in the said application.

As a means for feeding the strips to and from thei press, arrange in, advance of said press suitable feeding mechanism 25. This feeding mechanism may be variously constructed. As shown, there is a shaft 26 which is held in the outer end of arms 27,` the latter being pivotally held, at 28, to brackets 29 forming a part of the frame of the machine. The free ends of the arms 2.7 are normally forced downwardly by springs 30, one end of which is secured to the arms and the other end to a part of the brackets 29. On the rod or shaft 26 on opposite sides thereof and adjacent to but over the sides of thel machine frame are grooved wheels or elements 31 which are adapted to cooperate with rotary elements or wheels 32 having ribs 32al which enter the grooves in the wheels 31 and between which wheels 31 and wheels 32 the folded metal strips pass. The wheels 32 are supported on a shaft 33 arranged in vertical alinement with the shaft or rod 26. Y rilhe grooved element or wheel 31 and the wheel 32n are held to spur

gears

34 and 36, respectively, and rotate in unison therewith on the stationary shaft or

rod

26 and 33, said grooved wheel 31 being prevented from moving lengthwise of the shaft 26 by collars 35. The gears 34 are each in mesh with the spur gears 36, the latter being secured by screws or otherwise to the ribbed elements or wheels 32. The gears 36 are each held to or formed as a part of one member 37 of a clutch 38, the member 39 of each of said clutches being held to rotate with a pinion 40. Each pinion 40 is adapted to mesh with the teeth of a vertically reciprocatory rack 41. The racks 41 are each suitably guided in the frame or brackets located thereon. At their upper ends the racks are angular in form, as at 42, in which are arranged adjustable stops 43 in the form of bolts or screws which are adapted to engage parts 44 of the brackets 29. rIhe lower ends of the racks 41 are reduced and. arel guided in sockets 45 of a cross-head 46,. the latter being guided between the sides of the frame. The racks 41 are normally forced downward by springs 47, one end of each of which is secured to one of the racks and the other end to a fixed part of the frame, while the racks are moved against the tension of the springs 47 during the vertical movement .of the cross-head 46. This crosshead 46. is connected by one or more links 48 to the outer end of an arm 49.y This arm 49 is pivoted, at 50,. to a bracket on the frame and has a trundle 51 which is adapted to be engaged by a cam on the drive shaft 24, the said arm 49 being normally forced downward by means of a. springy 5.3 or otherwise. As the racks 41 are independently adjustable, different distances of feed or the same feed if preferred for the two strips of binding'l metal may be obtained.v The downward movement of the racks 41 is limited by the screws or bolts 43 and as the lower ends of the racks are free to move. in the sockets 45, the cross-head'46 may move of the machine frame.

a certain distance before it operates and moves one of the racks 41 and then further movement may operate the second rack. It will be noticed in Fig. 2 that the vrack at the right hand will be operated a greater distance than the one on the left hand because the cross-head or the socket piece 45 will engage the lower shoulder of the rack on the right hand before the socketvon the left hand engages the shoulder Vof the rack on that'side of the machine. 1n this way a very nice adjustment may be secured whlch may vary in extent and inwhich the feed of the two'strips may be the same or the extent of feed of one strip made to exceed that of the other.

Each of the'strips of metal binding is tilted so as to present one side substantially vertical in order that the strips may be bent properly about the anvil or vformer and that it may be in position better to receive thefolded shocks' forming the boX Ybody prior to being clenched or bound thereto.v

As shown, the framev may support two guide bars V54C and 54a which are held together by screws 55 or otherwise to form a lengthwise channeled guide for the metal strips on opposite sides of the machine. rllhe guides have channels 56 which are adapted to vary in shape lengthwise of the guides. As shown in Fig. 31, the guide channels or grooves 56 receive the strips in substantially the positionit is formed by the press. At the section where Fig. 32 is taken and as indicated inFig. 1, the groove may be of a circular form in cross-section, while at the point where the section Fig. 33 is taken, the groove is of the form or shape of the folded metal binding with one side substantially vertical. Located between the points where the sections Figs. 31 and 32 are taken, and forming substantially a continuation of the guides and on opposite sides of the machine, are tilting rolls shown best in Figs. 1 and 34. A grooved roll or member 57 is held to rotate on a stud 58 and this stud is held von the outer end of an arm 59, the latter being pivotally held to a bracket or part A ribbed roll 60 is held to rotate on a stud 61 which is held to the machine frame and said ribbed roll is adapted to cooperate with the roll 57. These rolls are angularly arranged with respect to a vertical plane and the grooved roll 57 is yieldingly forced toward the roll 60 by a spring 62, one end of which may be attached to the machine frame and the other end to a part of the arm 59. The shape of the rib of theroll 60 and the groove of the roll 57 correspond to the shape in cross-section of the folded binding strips, and during the forward feed of the strips, the latter will be caused to be tilted and the tilted strips guided through the guide grooves 56,

there being a set of tilting rolls for each of the strips.

Each strip after it has been fed inward the proper distance and tilted as previously described, is cut transversely theV proper length. In Figs. 5 to 10, I show one form of cutting means which may be employed. rlhere is a cutting device or means for each strip but as they are substantially the same in construction, a description of one will answer for that of the other. A bracketor frame 63 has a base 64 and is located forward of the tilting means already described. The frame 63 has its base provided withV openings through which the body of bolts 65 are adapted to pass so as to securely hold the frame or bracket 63 to the main machine frame. T he heads of the bolts 65 are movable in slots 66 in the machine frame to adaptthe frame or bracket -63 to be moved lengthwise thereof in order that the cutting or shearing means mounted thereon may be Y rocate in the casing 67. This cutter is disklike or circular in formand has a plurality of grooved cutting portions 69 about the periphery thereof any one of which is adapted to serve as one member ofthe cuttingk means. The cutter G8 is adapted to be rotatably adjusted about the end 70 of a pin or bolt 71 and said cutter'is normally held against rotary movement by a screw or pin 72, said pin or bolt 71 serving also as a set, screw or clamping means for the cutter V68. At the rear of the cutter 68 is a socket piece or reforming block 73 having a groove 74 in the lower edge thereof which is adapted to .form a continuation of oneV ofthe cutter grooves. This reforming block 73 is connected to a rod 75, the upper end of which is guided in the end of a sleeve or thimble 76 and is provided with lock nuts 7 7 on the outer end thereof. A spring 78 is arranged around each rod and tends normally to force the reforming block or socket piece 73 downward. A cutter or shearing member 79 is located under the reforming block 73 and is adapted to move toward said reforming block, the said member 79 being adjusted to cut properly by a screw 7 9a. YThe cutter member 79 is in the form of a tooth ioo There is a rack member 82 which also engages the teeth of the toothed rod 81 which is opposed to the toothed member 80 so that on the rotary movement of the toothed member 81, the

rack members

80 and 82 will be forced in opposite directions. The rack 82 carries the cutter member 68 as well as the socket piece 7 8 so that when the metal binding is fed between the same and the two members are brought toward each other through the rotary movement of the toothed rod 81, the cutting edge 88 of the cutter member 79 will be forced past the edge of the cutter 68, the. socket piece yielding during this movement, which will cause the binding to be severed. At the time that the strip is severed, the end may be reformed by the block or socket piece 78 and member 79 so that when the strips are bent about the anvil or former the lapped ends will lie substantially flush. As soon as one cutting edge of the cutter 68 becomes worn, the screw 71 is releasedV and the screw 72 moved out and the said cutter member rotated until the next cutter groove 69 is in position when the screws are again adjusted to hold the cutter. This may be repeated so long` as any one of the cutter grooves is adapted for use. The toothed rods 81 may be simultaneously rotated in the same direction by any suitable means. As shown, Figs. 1 and 11, one rod has an arm 84 projecting upward therefrom and the other toothed rod or shaft has an arm 85 projecting downward therefrom. These arms are connected by a transversely extending rod 86. An arm 87 lprojects outward from the arm 84 and said arm 87 is connected to a vertically reciprocating rod 88 which may be operated by a cam or otherwise so that at each reciprocation thereof, the

arms

84 and 85 will be rocked to rotate the toothed rods or shafts 81 and thereby move the cutters so as to sev-er the metal binding strips.

The metal binding` strips before being cut oit are fed into the j aws of transverse bending mechanisms and are severed while held by said mechanisms. One strip is fed to the mechanism 89 and the other strip to the mechanism 90 and these mechanisms are adapted to be moved transversely of the machine so as to bend the strip partly about a former or anvil 91 to substantially the shape of the box body and in such a way that the ends of the bent strips will overlap and form in substance a single binding for a box body. Except as to several features of the lapper jaws of the mechanism 90 to be pointed out later, the two

mechanisms

89 and 90 are identical and operate in the same manner and a description of one except as to such features will answer for the other and like characters will be used to designate similar parts. The mechanism 89 comprises a `central member 92 to each end of which is pivotally held a bending jaw 98. There are two of such jaws each of which is provided with a grooved bar 94 corresponding in shape to substantially onehalf of the metal binding when viewed in cross-section and which serves as a guide and holder for the metal binding. This bar 94 forms substantially a continuation of a similar bar 95 of the center member 92 so that the strip is guided by said bars substantially throughout its entire length. The member 92 comprises a guide member 96 having a dovetailed part 97 in which the two parts of the member 98 are held. The member 96 carries the bar 95 and to said member is held by rivets or otherwise one part of the member 98, the other part being yieldingly held to the fixed part so as to be forced toward each other by a spring 99, Fig. 25, and the ends of the spring 99 are attached to the lugs 100 and assist in moving the jaws 98 to their open position to receive the strip. Each part of the member 98 has a lug 100 to which is pivoted one of the jaws 98, the said jaws being provided with recesses 101 for proper coperation with the former or anvil 91, as will be presently described. The jaws 98 are pivotally held, at 102, to arms 108. There are two arms 108 and said arms each have a lug 104 which is adapted to form a stop for a projection 105 extending outward from the jaw 98, a spring 106 being provided tending normally to hold :the projection 105 against the stop 104. The arm 108 is hinged or pivoted, at 107, and is formed integral with a guide arm 108. There are two guide arms 108 and each guide arm has a straight surface 109 which is adapted to engage a roll 110, the latter being mounted upon an adjustable bracket 111 secured to a part of the machine frame, the said bracket being adjustable by means of a bolt 112 or otherwise. The pivot 107 extends through a lug or projection 118 of a bracketor support 114. There are two brackets 114 which are secured to the outer ends of a rod or shaft 115. This shaft 115 is mounted in the lower end of projecting arms 116 of a slide frame 117, the latter being guided upon a guide bar 118 which is secured at one end to the projecting part 119 of the frame bracket 120 and at the other end 121 to a frame bracket 122. The bracket 0r slide 117, arms 116. rod 115 and brackets 114 form substantially a cross-head for the mechanism 89. The slide 117 may be provided with adjustable gibs 128 for taking up any wear that might occur in the slide and the rearward movement of said slide and parts mounted thereon is limited by means of a bolt 124 which passes through and may be locked to a lug on the end'121 of the frame bracket 122. The slide i continue to move while the member 92 remains stationary and this will cause the jaws 93 to be moved on their pivots against the tension of the springs 106 about the corners A of the anvil so as to fold the outer ends of the strip on opposite sides 129 of the anvil, the said folded strip being held to the anvil and retained thereon on the return movement of the cross-head and bending jaws.

The grooved bars which initially receive the folded strip are open at one side and when'initially received, the lengthwise folded strip is held in the groove at this time fia . by a bar or shutter 130 which is supported by two pivotal arms 13011, the latter being held to a transversely extending 4rod 131. This rod 131 is mounted to rotate in brackets attached'to-the frame bracket 120 and said rod has an arm 132 which is adapted to be oscillated by a cam or otherwise operated lever 133 so that immediately before the member 92 and jaws 93 are moved forward to a folding position to advance the strip against the anvil, the bar Orshutter 130 is raised.Y The folding jaws are provided with retaining fingers 134 to hold the strip in place after the shutter 130 is raised Vand during the folding operation until the folding is nearly completed, said lingers being pivoted to lugs 135. These fingers have their forward ends 136 extending downwardly and are adapted to hold the strips in the grooved bars 94 of the jaws during the forward movement of the cross-head. The fingers 134 are automatically released just prior to the last part of the folding operation by the engagement of the ends 137 with tixed projecting parts, as cams 137, Fig. 11, so that the jaws can continue the remaining short distance to swing the vends of the strip against the anvil and in order to leave the strip on the anvil when the jaws are returned to their normal position, the anvil being notched, as at 137), in the sides thereof for the end of the fingers 134 to enter. The fingers 134 are normally pressed to an engaging position by means of springs 138 or otherwise. The bar 95 of the center carrier member of each of the

mechanisms

89 and 90, may be alined during the backward movement with the bars 94 of the jaws by engaging with the ends of adjustable screw stops 138%- Fig. 23, arranged in fixed frame lugs or brackets 1381.

I have described in detail the action vof the mechanism 89 without particular reference to the Vmechanism 90. This mechanism 90 is substantially the same construction and operates in a similar manner to the mechanism 89 and the same reference letters corresponding to like parts of the two mechanisms are used to indicate like parts, theV main difference between the two mechanisms being that the jaws of the mechanism 90 have a part thereof constructed so that the ends of the strip carried by the mechanism 90 as it is advanced toward the former or anvil 91 is adapted to be forced downward so as to lap under the ends of the other folded strip. These jaws of the mechanism 90 I term the lapper jaws, and the mecha- 95 of the carrier or intermediate member 92. The member 140 with the bar has a tongue and groove connection, as at 142, with each lapper jaw 139, and said tongue and groove connection inclines at an angle, as shown best in Fig. 17. The member 140 is pivoted, at 143, Fig. 17, so that its outer end will swing downward and is adapted to carry therewith the outer end of the metal binding so that it may beY forced under and into the ends of the strip bent by the mechanism 89, the strips being somewhat longer than isnecessary to extend s'ubstantially midway of the anvil 91 in order to provide overlapping ends. The members 140 of the lapper jaws 139 are` normally forced upward by means of springs 144 arranged around the screws or bolts 145, and said members 140 are adapted to be moved downward during the swinging f folding movement for bending the strip about the anvil by means of cams 146, Figs. 20 and 27, of the clenching mechanism in substantially the same manner as disclosed in my Patent No. 1,154,610.

The mechanism 90 has fingers 134 in the jaws for retaining the metal strip in the grooved bar 141 as in the mechanism 89 and also has the initial holding shutter 130 with the supporting arms 130a as'described in connection with the mechanism 89. The rod 131 of the mechanism 90 has an arm 147 which projects downward and this arm is connected by a rod 148 with an arm 149 which extends upward from the shaft 131 Vof the mechanism 89 so that on the reciprocation of the rod 133, the two rods 131 on opposite sides of the anvil or former 91 will be operated in unison and in opposite directions to adapt the shutter 130 to be raised when the mechanisms are moved to bend the strips about the anvil or former, the mechanism 89 being adapted to move slightly in advance of the mechanism 90, though the two mechanisms may move simultaneously if preferred.

The ends of the metal binding folded about the anvil or former by the

mechanisms

89 and 90 may be supported and held in any desired way. As shown, I provide two hooks or latches 150, Figs. 28 and 29, and two others 151, shown in Fig. 30, though this number of either or both forms of latches may vary. The latch 150 is of a lixed character and the latch 151 of a yielding character, there being two of each, the spring latch or catch being adapted to cooperate to hold the strip bent by the mechanism 89, and the latches or catches 150 being adapted to coperate to hold the ends of the metal binding folded by the lapper mechanism 90. The latch 151 is pivotally held, at 152, in a socket piece 153. This socket piece 153 is adapted to be inserted in a recess or opening convenient to the anvil 91 and may be held therein at the outer end by the end of a plate and may be adjusted outwardly at the rear end by means of a screw 154. The hook or latch 151 has a slot or groove 155 which is adapted to receive the end 156 of a spring 157, the latter tending normally to force the outer end of the hook or latch downward.' The outer end of the latch 151 has a curved lower surface 158 and a lip 159 which is adapted to engage under the lower edge of the substantially U-shaped binding strip. As the strip is folded about thefanvil or former 91 by the mechanism 89, the ends will engage the curved portion 158 to raise i, the latch on the pivot to permit the strip to pass by and as soon as the strip is against the anvil, the outer end of the latch will be forced downward by the spring 157 so as to cause the lip 159 of each latch to engage the end of the metal binding. As the ends of the strip folded by the mechanism 90 are forced downward by the jaw members to permit lapping, the latch 150 in such cases does not have to be pivoted but may be of a fixed character. The latch 150 has its lower end provided with a lip 160 which is adapted to engage the under edge of one side of the folded strip and said latch has its body portion 161 held in a socket piece or box 162, the said body 161 being provided with a projecting lug portion 163 to abut against a shoulder 164- of said socket piece. The socket piece 162 fits into a recess adjacent to the anvil or former 91 and may be adjusted outwardly by means ofa screw .165. The

box may be held in its adjusted position by means of a tapered screw 166 arranged at one side of the box or socket piece. When the metal binding has been clenched about the box form as will be presently described, the clenching operation will compress the metal binding to such an extent as will release the edges thereof from the engaging lips 159 and 160 of the

latches

150 and 151 respectively, so that the binding or metal rim with the box form may be removed.

rIhe anvil 91 and certain parts coperating with the folding jaws of the

mechanisms

89 and 90, is shown in a measure diagrammatic in Fig. 11, and the construction and arrangement thereof is shown more in detail in Figs. 20 to inclusive. rl`he anvil is also shown rectangular and square but it may be oblong or of any other desired form and the mechanism for folding the rim or binding about the same may be correspondingly changed. As shown, the anvil 91 has corner pieces 167 which may be integral with the body or separate therefrom and about which the binding is formed. The anvil is held to a vertically movable head 168. This head 168 may havo a sleeve portion 169 about which is an adjustable tubular and sleeve-like stop 170, the lower end 171 of which is adapted to engage the upper edge or surface 172 of said head when the latter is moved to its elevated position as will be presently described. The anvil head 168 is provided with extensions or parts 173 about the same which serve to prevent the rim or binding from being forced about and off the anvil when the box body is inserted therein, and above the head 168 is a casting or member 17eL at the four corners of which are socket pieces 175. 175 are the pins 128 which are held thereto by means of screws 17 7 or otherwise. The pins 128 serve to form bearings for the recesses or sockets 101 of each of the folding jaws and serve as a pivot for said jaws during their swinging movement to bend the binding about the anvil. During the folding operation, the anvil is normally below the clencher mechanism or means which forces the binding about the box body and in the position shown in Figs. 21 and 22, but as soon as the binding or rim is to be bound or clenched to the box body, the head 168 with the anvil will be moved upward by a spring, not shown, or otherwise and until the surface 172 of said head will engage the stop 171 as will be further described in connection with the clencher and box-forming mechanism.

TWhile this invention refers more particularly to means whereby the binding or metal rim is formed and applied to the box body, l have shown in a general way one form of In the socket pieces A mechanism for making the box body from shooks of wood veneer or other material.

This part-of the mechanism may be automatic in character taking the shooks automatically from magazines and forming the same into box form and placing the box body in position to have the metal rim or binding clenched thereto in substantially the manner disclosed in my Patent No. 1,154,610, or the said mechanism may be of any suitable kind either automatic or operated by hand. As shown in Figs. 1, 20, 21 and 22, the shooks may be arranged in two magazines 178 and 17 9 from which the vshooks are removed in succession by a pneumatic picker 180. This pneumatic picker has a rotary and reciprocatory movement and is provided with a plurality of arms 181 each of which has pneumatic or other devices to remove the shooks and to hold them in pairs crosswisc and place them in this crosswise position in a turret or carrier 182. The turret, carrier or holder comprises four receivers 183. ceive an intermittent rotary movement and is adapted to take the shooks in a crosswise position and place them between the punch mechanism 184 and the die mechanism 185. Each receiver may have fixed members or clips 186 each of which has an overhanging lip 187 under which the shooks are adapted to be forced when deposited therein by the pneumatic picker or device 180 and in such a way that the uppermost shook will not spring or bend far enough'to engage the lower shook, the said shooks being adapted to be removed by the punch and die mechanism.

The die mechanism comprises a base or l bottom piece 188 and a rubber suction member 189 which is held to a vertically movable tubular member 190 connected to the die head 191. The tubular member 190 is adapted to be connected to suitable pneumatic suction means to adapt suction to be created and destroyed therein so that suction may be exerted on the bottom of the box after being completed for the purpose of stripping it from the punch 184, the bottom of the plate 188 as well as the tubular screw 192 for holding the plate in position being slotted or grooved along the upper surface thereof to permit air to be drawn within the tube or connection 190. Around the bottom or base 188 are four yielding bottom plates 193 and movable about said bottom plates are four wings 194. Each wing 194 has a presser plate or member 195 at the outer end thereof and each wing at its inner end is provided with recesses which are adapted to be engaged by spring-pressed bolts 196, the spring being interposed between the head of said bolt and a lug 197. The wings 194 are connected to arms 198 and these arms are connected by links 199 to the die head and in such a way that during the folding movement of the die, the

This turret is adapted to re-V wings attheir inner ends will move about the edges of the yielding bottom plates y193 with a lapping effect and in such a way that the shooks at the pointof fold will be held and prevented from breaking or slivering particularly when the shooks are made of wood. The die mechanism moves bodily upward through one of the receivers of the turret and meets a presser foot 200 of the punch 184. lThis punch has

members

201 and 202, the latter having four yielding sides 203, the latter being forced outwardly by springs 204 and limited in such outward movement by screws 205 or in any other suitable way. Above the yielding sides 203 is the anvil or former 91 about which the metal strips have been formed and which metal strips have been bent substantially rectangular in form to correspond to the shape of the box form with the folded edges downward so that during the upward movement of the die with a part of the punch mechanism which has been moved downward to meet the die to clamp the shooks and which is folded during the upward movement of the die and punch mechanism, will receive the upper edges of the box form.

The binding or rim is adapted to be forced or clenched about the box form by any suitable mechanism. AS shown, levers 206 are pivoted, at 207, about the punch and at their upper ends are connected by toggle links 208 to a movable part or sleeve 209 which is adapted to force the lower ends of said levers 206 toward or away from the anvil. At the lower part of each arm 206 is a clencher jaw 210 which when the anvil is moved after receiving the box form to a position in alinement with said gripping jaws, the latter will'be operated so as to clench the binding or rim securely to the box body. The clenching is done at the lower edge of he rim of the box body which is necessarily narrow and in such a way as to force the same into the wood and thus make substantially a dovetailed connection with the wood. As the wood is more or less damp when the box body is made, it will diminish in thickness when it becomes dry and will have a tendency otherwise to become loose from the metal rim, but by clenching the rim in the manner disclosed so that the lower edges are bound into the wood to squeeze the wood substantially dovetailed at the upper edge, the wood body cannot become detached from said rim, the latter, during the clenching operation, being released from the latches or hooks 150 and 151 as already described. During the clenching operation, the anvil is raised by a spring or otherwise until the end 171 of the sleeve stop 170 engages the surface 172 of the anvil head 168. The head 168 and member 202 of the punch are forced downward and held in this position to place theanvil in alinement with the folding mechanism by the downward movement of the sleeve 209 engaging the upper end of the sleeve 169 which forms an extension of t-he anvil head 168. After the box or basket is formed, suction is created in the tubular member 190 which together with the presser foot 200 will strip the box from the punch and will deposit the same in substantially Y-shaped brackets 211 located in the four corners of each receiver 183 of the turret or carrier 182,when on further movement of the turret to place another set of shooks in position to have the box form made, the completed box will be carried away out of the path of the punch and die mechanism in a convenient position for ejecting or other means. rlhe parts as thus described relating to the means for making the box form, are substantially the same as disclosed in my application hereinbefore referred to.

The link connection 125 shown in detail in Fig. 24 for operating the cross-head of the

folding mechanisms

89 and 90, may be variously constructed. As shown, it comprises essentially two members 212 and 213 which are yieldingly held together so that it will be impossible for the parts of the mechanism to be broken if the parts are not adjusted exactly'when the folding jaws and carrier members are moved toward and against the anvil. rl`he member 212 has a threaded stem 214 and locked to .this stem is a sleeve or thimble 215. rlhe stem 214 has an opening 216 in which the end 217 of a rod 218 of the member 213 is adapted to slide. On the rod 218 are lock nuts 219 and interposed between the lock nuts 219 and the threaded stem 220 of a member 221 is a spring 222. The sleeve or thimble 215 is held to the threaded stem 220 of the member 221, and said member 221 forms a guide for the outer end of the rod 218. The two members 212 and 213 are therefore connected together so as to form a yielding connection between each cross-head of the folding mechanisms and its operating lever 126.

The operation of the invention will be readily understood from the foregoing description when taken in connection with the accompanying drawings. The two metal strips having been fed into the machine on y*opposite sides thereof are advanced forward by the feed mechanism the desired distance, the said strips having been bent or folded lengthwise by the press 11. As the strip is advanced forward after being folded lengthwise, it is tilted by the guides and tilting rolls and suitably guidedv into the folding and lapper jaws of the

folding mechanisms

89 and 90. The shutter 90a is raised and the folding jaws with the cross-heads are moved toward the former or anvil 91 fromv opposite sides thereof and during such folding movement the jaws will pass about the' an1y vil or former, the ends of the strip carried by the lapper jaws 139 of the mechanism 90 being forced downward so as to lap under the ends of the strip folded by the mechanism 89, the ends of the folded strips being held by the

latches

150 and 151 as already explained. The boX form or body during the time that thc folding of the metal binding is taking place, has been proceeding, and said box form when folded by the punch and die mechanism as already explained, will be fed into the binding and clenched thereto by the jaws 210 of the clenching mechanism.

ln 35 to 39, a construction somewhat different from that shown in the other views and particularly in Fig. 2 is provided for feeding two lengthwise folded strips either the same or different distances preparatory to the same being cut and bent around the anvil. This construction is somewhat simpler than thatshown in the other figures and ordinarily l prefer to use this construd tion of feed. It differs from that shown in Fig. 2 primarily in using a different form of clutch or ratchet mechanism and in employing a single rack and pinion instead of tvfo racks and pinions which cooperate with said racks. The grooved members, rolls or wheels 223 are rotatably held upon a shaft 224, the latter being carried by pivotally held arms 225. The arms are normally forced downward by springs 226, one end of which is held to the arms and the other ends being held to the machine frame. The springs 226 tend to force the grooved wheels 223 toward the ribbed wheels, rolls or members 227. Each wheel 227 is provided with a gear 228 which is in mesh with a similar gear 229, the latter being movable with one of the grooved wheels or rolls so that the grooved and ribbed wheels may rotate in unison. Each ribbed roll or wheel 227 is provided with a hub or drum portion 230, the inner part of which is provided with ratchet teeth 231 forming an intern al ratchet wheel. The ratchet teeth 231 are adapted to be engaged by pawls 232 which are pivoted, at 233, to the outer ends of arms 2311. rl`hc arms 234 for each wheel form a lever which is held to a transversely extending shaft 235 by means of a key 235a or otherwise so that when the shaft 235 is rotated or oscillated as will be presently described, the pawls 232 will engage the ratchet teeth 231 of each wheel 227 and will rotate the same about the shaft 235. There are two pawls for each wheel 227. The pawls are arranged diametrically opposite each other and each pawl' is normally forced to an engaging position by means of a spring 235b one end of which is seated in a recess in the pawl and the other end lin a recess in the pawlcarrying arm 234.

g The ribbed wheels 227 are loosely mounted ELO upon the shaft 235 and areheld against lengthwise movement on said shaft. A. pinion 236 is held to the shaft substantially midway between the gears 228 and adapted to engage said pinion is a toothed rack '237. This rack is adapted to move vertically and may be reciprocated by any suitable means such for example as links 233. As the rack 237 is reciprocated, it rotates the pinion 23 and this will rock the shaft 235and move the pawl-carrying arms 234. rlhis will cause a rotary movement to be given tothe ribbed wheels 227, which, owing to the intermeshing gears 228 and 229, will impart a like rotary movement to the grooved wheels 223.

As a means for regulating the extent of movement of the feed rolls, the pawls 232 may have their engagement with the teeth 231 regulated. T his may be secured in various ways. As shown, a lever oi element 239 for each set of pawls is loosely mounted upon the shaft 235 and cach outer end of said lever carries a cam portion 240 upon \\'hirh tlie pawls 2"2 may ride for a part of their movement. Each lever 239 has a slotted extension 2ll through which passes a pin or bolt 2112. The bolt 24:2 extends through a lug 243 on a. part of the machine frame so that by means of said bolt, the position of the lever 239 and the cams 240 may be changed relatively to the normal poH sitien of the pawls 232. By moving the cams 240 away from the pawls, the latter will engage a greater numb Ar of teeth and'eonsequently a greater throw or movement will be imparted to the feed rolls, and the reverse takes place when the cams are moved toward the pawls, for in that ease the pawls in their movement in one direction will be disengaged sooner from the teeth 231, and the means for disengaging the pawl by the cam 240 being more clearly shown in Fig. 38.

By shifting the cams 240 on one side of the machine differently from the cams on the other side of the machine, the feedV rolls or wheels will be moved diierent distances and different extents of feed will be obtained for the binding metal, while by having the cams on both sides of the machine similarly adjusted with respect to the pawls 232, the same extent of feed of the metal binding is obtained.

From the foregoing, it will be evident that folding and bending the strips and for holdf ing the same about an anvil or former; that simple feeding and cutting mechanism is provided whereby the strips may be fed the .shown and described as adapted particularly for machines wherein the entire basket is made automatically, the said mechanism or parts thereof may be of such a character that they may be employed in Yvarious connections and for making boxes of various sizes.
