JOSEPH IRON WORKS, OF ST. JOSEPH, MICHIGAN, A CORPOBATIGN OF MICHIGAN BASKET-MAKING MACHINE Application filed April 3, 132

My inv ntion relates to machines for making baskets of the type having a tapered annular wall composed of panels which are secured at their lower ends to the basket bottom and retained in the tapered form by hoops which are spaced from the bottom and secured to the panels, and my invention has reference more particularly to a machine whereby a previously formed shell consisting of the basket bottom with panels secured therearound in substantially cylindrical form, is flared or expanded into the required tapered form and has the hoops applied thereto to maintain the tapered form.

In the manufacture of baskets of the above character, it has been found desirable to first make up a basket shell by securing the panels which compose the annular wall of the basket to the basket bottom, in which form the panels take substantially the form of a cylindrical shell, and thereafter to expand the cylindrical shell into the required tapered form and retain the panels permanently in the latter form by securing the usual upper and intermediate hoops thereto.

ihe principal objects of my invention are to provide an improved machine for expanding basket shell and applying the hoops thereto; to arrange the machine so that it opcrates automatically under the control of the operator to expand the shell and thereafter apply the hoops and fasten same to the shell in the expand-ed form; to insure a uniform tapering of the shell; to automatically lap the upper ends of the panels of the annular wall over the internal hoop at the upper end of the basket; and in general, to provide a simple and convenient machine for making baskets of the type above referred to.

Referring to the drawings, the reference numeral 1 indicates the base of the machine which is provided at one end with a pair of spaced frames 2 and 3, with a top plate 4 connecting their upper ends, and 5 is a shaft which is ournaled in the frames 2 and 3 and has the basket form 6 secured to the inner end. A drive shaft 7 is journaled in the frames 2 and 3 near their lower ends and has a drive pulley 8 thereon which connects with the shaft 7 through a friction clutch 9 which is operated by the pedal 10. A spring 11 normally holds the pedal 10 in the elevated posi tion in which the friction clutch 9 is disengaged and the pulley 8 free to rotate on the shaft 9, and the pedal has an extension 12 connected with a brake band 13, so that the latter engages the brake drum 14 on the shaft 7 for stopping the latter when the friction clutch 9 is released and saidbrake band is released from the brake drum and allows the shaft 7 164 in the housing is loose on the shaft 20 and' to rotate freely when the clutch pedal 10 is depressed to engage the friction clutch 9.

A counter shaft 20 is journaled in the frames 2 and 3 above the drive shaft 7 and operated from the latter by a chain drive 21 through a friction driving mechanism 24, which exerts a constant driving strain on the shaft 20, but is adapted to slip when the shaft 20 is held against turning movement. A pinion 25 is fixed on the shaft 20 and meshes with a large gear 26 which is fixed on the shaft 5 so that the shaft 5 and the basket form 6 is rotated from the drive shaft 7 through the friction drive 24, the arrangement of the driving mechanism being such that a relatively low speed is imparted to the shaft 5.

The friction driving mechanism 2L may be of'any suitable type, for example as shown in Fig. 15, wherein the sprocket 160, driven by the chain 21, is loosely mounted on the shaft 20 and has a housing 162 secured to one side thereof. A disk 163 in the housing is fixed on the end of the shaft 20 while another disk held against the disk 163 by a number of springs 165 arranged at intervals around the shaft 20, said disk 164 being caused to turn with the sprocket 160 by a number of pins 166 secured to the disk 164 at intervals around the shaft 20 and slidably engaging in sockets in the hub of the sprocket 160.

The form 6, upon which the basket shell is mounted, while the upper and intermediate hoops are applied thereto, is advanced in a step by step manner in order that the staples may be applied at proper intervals around the hoops, and the stapling mechanism is operated from the drive shaft 7 so that a stapling 0 eration is effected in each revolution of tli In order to effect the step by step movement of the shaft 5 and form 6, a disk 27 is fixed on the shaft 20 and provided at suitable intervals with projections or stops 28 and a bell crank lever 29 is pivoted on the frame 2 so that the upper arm 30 thereof may be swung to and from the path of moveme't of the stops or projections 28 to hold the shaft 20 at the proper time against the driving tend ency imparted thereto through the friction mechanism 24 and at such time a slipping action, occurs between the members of the friction drive mechanism 24. The lower arm 31 of the bell crank 29 extends downwardly to a position adjacent the drive shaft 7 and is provided at the lower end with a roller 32, which is held by the spring 33 in contact with a cam 34 on the shaft 7, and this cam 34 has a rise or enlargement 35 at one side which is arranged to shift the upper end of the bell crank 29 out of the path of the stop 28 when the stapling mechanism is retracted from the form 6, and the shaft 20 is thereby permitted to turn and rotate the drum 6 to e shaft 7.-

the position of the next stapling operation. The cam 34 is formed so that it only momentarily shifts the upper end 30 of the bell crank 29 from the path of movement of the stop or projection 28 so that said upper end is immediately returned bythe spring 33 to engage the next succeeding stop or projection 28 and arrest further movement of the shaft 20 and drum 6 during the remainder of the revolution of the shaft 7, during which time the stapling mechanism is operated to apply staples to the hoops which are being attached to the basket shell on the form 6.

In the present structure, a shell is intended to be used which has the outside bottom hoop 36 already attached, and stapling devices 37 and 38 are provided for fastening the upper and intermediate hoops respectively to the basket shell on the form. These stapling devices are of the usual form and the stationary parts thereof are carried by a bracket 39 which swings on a tubular standard 40 which projects upwardly from the plate 4, so that the stapling devices may be swung away from the operating position over the form 6 when the basket shell is applied to the latter and may be swung back to the operative position when the basket shell is in position on the form 6. A shaft 41 extends upwardly through the standard 40 which supports the bracket 39 and has a laterally extending arm 42 fixed to the upperend and carrying the reciprocating parts of the stapling devices 36 and 37, and the shaft 41 extends downwardly below the plate 4 through a guide 45 and has a swive connection 43 at its lower end with the arms 46 of the eccentric strap 47 which embraces the eccentric or cam 48 on the shaft 7, whereby a stapling operation of the stapling devices is performed at each revolution of the shaft 7.

The basket form 6, which is shown in detail in Figs. 5, 6 and 7, is of substantially the tapered form of the finished basket and comprises an annular shell 49 carried by a web 50 which has a hub 51 keyed as at on the reduced end of the shaft 5 and provided with clinch rings or hands 53 and 54 respectively for clinching the staples which are driven through the upper and intermediate hoops of the basket. The upper inside hoop 55 of the basket is placed on the form around the clinch ring 53 before the basket shell is applied to the form, said ring 53 having the beveled edge 56 to facilitate the placing of the hoop on the ring 53, and the form has an annular flange 57 at the inner side of the ring 53 to serve as a stop for properly locating the hoop 55.

As the basket shell is slipped onto the form 6, it is necessary to lift the ends of the panels 58 of the basket shell (see Fig. 12) sufficiently so they will pass over the hoop 55 on the ring 53 and thereafter close down thereagainst in order that they may be properly stapled to the hoop, and for the purpose of guiding the ends of thepanels 58 up over the hoop on the ring 53, the form 49 is provided between the clinch rings 53 and 54 with a series of annular recesses 59 for a plurality of expander wings 60, each of which is pivoted at 61 between a pair of lugs 62 in the annular recess 59. These wings comprise curved plates which in the contracted position, afford substantially a continuation of the tapered wall of the form 49 as shown in Fig. 5, but may be swung on their pivots 61 to an inclined position as shown in Fig. 6, so as to deflect the upper end of the shell sufficiently to pass over the hoop on the split ring 53. Each of the wings 60 has an inwardly extending arm 63, which has a slotted pivotal connection as at 64 with a spider 65 which is mounted to slide on an intermediate reduced portion 66 of the shaft 5, so that movement of the spider 65 along the shaft 5 serves to swing the wings 6O on the pivots 61 to and from the positions shown in Figs. 5 and 6. hen the basket is pushed onto the form 6 and particularly as the upper ends of the shell rise up over the deflector wings 60, there may be some tendency of the basket shell to tilt on the form or flare to a greater extent at one'side of the form than at the other side of the form, and in order to avoid unevenness or lack of uniformity in the flaring of the basket and to insure proper guiding of the open end of the basket shell onto the form 6, the latter is provided at the outer end with a yieldingly mounted plate 67, against which the bottom of the basket is clamped in the final position on the form 6.

This plate 67 has a hub portion 68 sliding on the hub 51 of the web 50 and held in the outermost position by a spring 69 which is interposed between the web 50 of the form 6 and the plate 67, the latter being held on the hub 51 against the tension of the spring 69 by V a disk 70, which is secured by the screw 71'or in any other convenient manner to the end of the shaft 5 and extends over an internal shoulder at the inner end of the enlarged opening 72 in the outer end of the hub 68. The outer end of the annular shell 19 of the form is composed of an annular series of fingers 7 3, the outer ends of which reach down to the bottom of the basket when the latter is placed on the form 6, and these fingers enter a corresponding series of peripheral notches 74 arranged around the outer edge of the end plate 67 so that the plate 67 may slide inwardly along the fingers 7 3 as shown by dotted lines at 75 in Fig. 6. The plate 67, which is slightly larger than the diameter of the annular shell 49 at the outer extremities of the fingers 73 so as to insure passage of the end of the panels 58 up onto the form 19 without interference, has an annular bevel 76 suitably arranged to positively guide the open end of the basket shell up onto the form 6. A cradle 77 is located adjacent the outer end of the form 6 to support the basket shell prior to and during the operation of starting the basket shell onto the form 6, this cradle being supported by a standard 78 on the base 1, and a pusher operates over the cradle 7 7 to and from the form 6 to apply the basket shell onto the form and clamp the basket bottom against the retracted plate 67 at the outer end ofthe form.

The pusher is mounted on a pair of spaced franfes 7 9 and 80 which extend up from the base 1 and comprises a plate 81 which moves with a carriage lengthwise of the base 1 to and from the outer end of the form 6. This carriage, which is indicated at 82, slides between supporting guides 83 which extend be tween and are secured to the upper ends of the frames 7 9 and 80, and has spaced bearings 84 and 85 slidably supporting the tubular shaft 86 which has the pusher plate 81 secured to the inner end. A spring 87 is in terposed between the hub of the pusher plate 81 and the bearing 84 so that the plate 81 yieldingly engages against the bottom of the basket on the form 6, and the spring 87 is held under compression by a collar 88, which is'secured on the tubular shaft .86 in a position to engage against the bearing 85.

For operating the carriage 82 and pusher plate 81, there is a drive shaft 89 journaled in the frames 79 and 80 and provided with a loose pulley 90 thereon having a positive clutch connection with the shaft 89. This clutch connection may be of any suitable form as for example, a sleeve 91 fixed on the shaft 89 and having a clutch pin or member slidable axially therein and operated by a spring to engage clutch teeth on the pulley 90. A longitudinally movable trip bar 92 is moun ed in a bracket on the frame 80 to move to and from the sleeve 91 and is normally held by the spring 93 in position to engage and withdraw the clutch pin, the construction being such that when the clutch shifter 92 is momentarily shifted to release the clutch pin or other clutch member, the shaft 89 makes a single revolution, whereuponthe trip member 92 which has in the meantime been re-v turned by the spring 93 to the normal position, disengages the clutch and the shaft 89 is held stationary until the member 92 is again operated. The clutch described is of the type illustrated in l. A shaft 9 1 is journaled at the side of the base 1 and has an arm 95 secured to one end and connected to the outer end of the clutch shifter 92 for controlling the operation of'the latter, and this shaft 94 at its other end, has a laterally extending pedal 96 adjacent the position of the operator at the center of the machine whereby the operation of the shaft 89 may be readily controlled. I

A beveled pinion 97 is secured on the shaft 89 and meshes with'a beveled gear 98 of suitable size so that the beveled gear98 makes loo one-half of a revolution when the shaft 89 makes a single revolution, and this bevel gear 98 is carried by an upright shaft .99, which is mounted in the brackets 100 on the frame 79. This shaft 99 has a crank disk 101 fixed to the upper end,-to which a pitman 102 is connected atone end, the other end of said pitman being pivoted to the outer end of the carriage 82 as at 103. lVith this arrangement it will be observed that when the clutch controlling member 92 is operated and the clutch engaged, the shaft 89 will make a single revolution at the end of which the clutch controlling member 92, which has been returned to the normal position, will disengage the clutch mechanism, and in view of the ratio of the beveled pinion 97 and beveled gear 98, the shaft 99 and disk 101 will make one-half of a revolution during the single revolution of the shaft 89, thereby pro jecting the carriage 82 and the pusher 81 inwardly toward the form 0 during one revolution of the shaft 89, and at the next revolution, the disk 101 will be rotated another half turn whereby the carriage 82 and pusher plate 81 will be retracted to the position shown in Fig. 1.

In order to cushion the return movement of the carriage 82, a U-shaped frame 104 is attached to the frameSO and projects around the outer end of the shaft 86, and this frame 104 has a rod 105 secured thereto which projects into the tubular shaft 86, and has a spring 106 mounted thereon so as to be com pressed by the carriage in the retracted position and cushion the return movement of the carriage.

The expander wings G0 serve to spread the open end of the basket shell as the latter is pushed into place on the form 6', and are timed in accordance with the operation of the pusher plate 81 so that they are swung to the expanding position shown in Fig. 6 as the basket shell ispushed ,on'the form 6 and so that they are retracted to the position shown in Fig. 5 when the basket reaches the final position on the form. To accomplish this operation of the expander wings 00 in. proper timed relation with the operation of the pusher81, a cam 107 is fixed on the shaft 99, and a rod 108, which extends through the frame 79 and under the form 6, has a head 109 at one end with a slot 110 embracing the shaft 99 and is provided with a roller 111 at the end which engages the face of the cam 107. The rod 108 slides in a sleeve 112, being yieldingly held therein by a pair of springs 113 which are connected at one end to a collar 114 on the rod 108 and at their other ends to a pivot bolt 115 on the sleeve 112, and the latter is pivotally connected at 115 to the lower end of abell crank 116,

which latter is pivoted intermediate of its.

ends at 117 on the standard 3. The upper end of this bell crank is connected in the usual manner to a ring 118 which is loosely engaged inan annular groove in the hub of the spider 65. A spring 119 is connected at one end to the frame 3 and at the other end to a collar 120 on the rod 108 so as to hold the roller 111 in contact with the periphery of the cam 107, which latter is formed with a gradually rising face which retracts the rod 108 and through the bell crank member 116, shifts the spider along the shaft 5 as to expand the wings 60 to the position shown in Fig. 6, andthis cam 107 has an abrupt offset 121 arranged at a suitable point so that when the disk 101 is operated to move the pusher 81 to the innermost position, at which time the inner end of the shell will have moved over the wings 60 on the form 6, the roller 111 will drop down from the offset 121 of the cam, thereby allowing the spring 119 to shift the rod 108 and the bell crank lever 110 to shift the spider 05 so as to snap the wings 60 back to the normal position shown in Fig. 5.

\Vhen the basket shell is applied on the form 6, it is desired to have the stapling mechanism swung away from the form so as not to interfere with the application of the basket shell on the form, and said stapling mechanism is through the pivotal mounting of the bracket 39 and the swivel connection of the shaft 41 with the links 46 permitted to swing laterally to and from the position over the form 6. In order that the adjustment of the stapling devices may be accomplished automatically, I have provided a shaft 122 which is journaled in the frames 3 and 79 and 80 and operated from the constantly driven pulley 90 by the chain drive 124 through the clutch 123. This shaft 122 has a bevel pinion 125 on the remote end meshing with a beveled gear 126 on an upright shaft 127 behind the shaft 41 in Fig. 1 and carried by a bracket on the frame 3, the ratio being such that the gear 126 makes one-half of a revolution in one revolution of the shaft 122 and pinion 125. A crank disk 128 is fixed on the upper end of the shaft 127 and connected with the bracket 39 so as to swing the stapling devices away from the form 6 prior to the operation of the pusher 81 which applies the basket shell onto the form 6 and to return the stapling devices to the stapling position as soon as the basket shell has been applied on the form 6.

The connection of the crank disk 128 with the bracket 39 may be effected in any convenient manner. In the present structure the hub of the bracket 39 has a lateral extension 130 which swings between and is cushioned by spring bumpers 131 and 132 at the opposite extremities of its movement, and this extension 130 has a pin 133 projecting therefrom. A lever 134 which is pivoted to the top plate 4 as indicated in Fig. 10 has the outer end connected by the link 129 with the crank disk 128 and the inner end of the lever 134, has an ar-cuate slot 135 cooperating with the pin 133 so that when the lever 134 is swung to the position shown by dotted lines in Fig. 10, the pin slides out of the notch 135 and is engaged by the wedge face 136 at the mouth of the notch 135 and clamps the arm against the bumper 132 so as to hold the stapling devices in the stapling position. When the lever 134 is thrown from the dotted line position of Fig. 10 to the full line position, the elongated finger 137 at the opposite side of the slot engages the pin 133, returning the latter into the notch 135 and at the same time shifting the stapling head away from the stapling position until the extension 130 comes into contact with the bumper 131.

The clutch 123 is similar to the clutch 91 and comprises a sleeve 139 which is keyed at 140 on the shaft 122 and provided with a clutch pin 141 on which a spring 142 exerts a tension to engage the clutch pin 141 with the clutch recesses 143 in the hub of the driven sprocket 138 which is connected by the chain 124 with the pulley 90. A bell crank 145 is pivoted on a shaft 146 which extends between the frames 79 and 80 and has the upper arm adapted to engage in a groove 144 of the clutch sleeve 139 to engage the head of the clutch pin 141 and withdraw same from engagement with the clutch recesses 143. The lower arm of the bell crank 145 extends down close to the upper face of the gear 98 and is connected with a spring 148 which normally holds the upper arm engaged in the groove 144. A cam 147 on the upper face of the gear 98 has a pair of projections 150 and 151 with recess 152 therebctween, the former of which, namely, projection 150, is arranged so as to engage the lower arm of the bell crank just as the pusher 81 completes its inward movement and thereby rock the bell crank 145 and permit the spring pressed pin 141 to engage the recess 143 so as to operate the shaft 122 a single turn and thereby swing the stapling mechanism to the stapling position above the form 6, whereupon the clutch 123 is disengaged.

Immediately after the cam projection 150 shifts the clutch controlling member 145 to release the pin 141 and permit the engagement of the clutch mechanism 123, the cam 147 moves to the position wherein the notch or recess 152 is adjacent the lower end of the bell crank 145 and permits the latter under the tension of the spring 148 to return to theeposition to engage and Withdraw the pin 141 so that the clutch 123 will be disengaged upon the completion of a single revolution of the shaft 122, and at the same time that the lower end of the bell crank 145 drops down in the cam recess 152, the clutch 91 is arranged to be disengaged by the shifter 92 0 th t t e h ft 99 and'cam 147 cease op ra tion with the lowerend of the bell crank 145 engaged in the recess 152.

After the basket has been completed and the pedal 96 is again depressed, to operate the crank disk 101 for retracting the pusher plate 81, the cam projection 151 immediately engages and shifts the bell crank 145 to permit engagement of the clutch 123 and rotate the shaft 122 a single revolution whereby the stapling mechanism is swung away from the form 6.

In the operation of this machine, a basket shell of the form shown in Fig. 12 is placed on the cradle 77, with the open end of the shell adjacent the outer end of the form 6, whereupon the pedal 96 is momentarily depressed, thereby engaging the clutch 91 so as to connect the drive pulley 90 with the shaft 89, causing the latter to make a single revo lution, whereupon the clutch is disengaged and the shaft 89 remains inactive until the clutch pedal 96 is again depressed. Upon the operation of the shaft 89 the disk 101 is rotated one-half revolution, thereby projecting the carriage 82 inwardly so that the pusher plate 81 engages against the bottom of the basket shell and pushes the latter up onto the form 6, the beveled edge 76 of the plate 67 serving at such time to insure proper guiding of the open end of the basket shell up onto the form. Previous to the operation of the pusher 81, the stapling devices have been swung laterally away from the position over the form 6 by the preceding rotation of the shaft 122 so that the stapling devices do not interfere with the application of the shell on the form, and prior to the time that the basket shell reaches the wings 60, the latter have been adjusted to the expanding position shown in Fig. 6, so that the wings are positioned to expand the open end of the shell so that it will pass over the hoop 55 which has previously been placed in position on the clinch ring 53 of the form 6. As the basket shell is moved up to the expanding wings 60, the basket bottom comes in contact with the plate 67 and is clamped thereagainst so that the basket shell is driven squarely onto the form, and in the final movement of the pusher 81 the plate 67 recedes against the tension of the spring 69 so as to hold the basket shell firmly in the proper position on the form. Just as the basket shell reaches the final position on the form 6, the roller 111 drops down over the shoulder 121 of the cam 107, thereby permitting the wings 60 to contract and the ends of the panels 58 to lay down against the hoop 55 on the clinch ring 53 on the form. Moreover as the basket shell nears the final position on the form 6, the cam pro= jection 150 swings the bell crank 145 and permits engagement of the clutch 123 and 0p erates the shaft 122 to return the stapling dc vices to the stapling position over the form 6. H P a d a hen fed h u ua manner lee into guides which lead them under the stapling devices 37 and 38 so as to form the upper outside hoop 153 and the intermediate hoop 154 of the completed basket, and the pedal is then depressed and held in the depressed position. Upon depression of the pedal 15, the pulley 8 is engaged with the shaft 7, thereby exerting a tension on the friction drive mechanism 24 to turn the shaft 5 and the drum 6. In each revolution of the shaft 7, the stapling mechanism is operated to drive staples through the upper and intermediate hoops and the panels of the baskets, and the u per staples pass through the inside u per 00p 55 which is on the clinch ring 53 oft e form, and each time that the stapling devices are retracted, the lever 29 is shifted b thecam 34 to disengage a stop or projection 28 on the disk 27 and to permit the friction driving mechanism 24: to advance the form a single step. The lever 29 immediately returns to engage the next pin or stop 28 and arrests further movement oi the drum or form 6, whereupon the stapling devices are 1 again operated to apply staples through the upper and intermediate hoops. lVhen the hoops have been stapled entirely around the basket, the pressure on the pedal 15 released, Whereupon the stapling mechanism becomes inoperative, the movement thereof bein promptly arrested by engagement of the rake band 13 with the brake drum 14, and the pedal 96 is again temporarily depressed. Upon pressure of the pedal 96, the clutch 91 is operated to permit a single rotation of the shaft 89, and thereby retract the pusher plate 81, and the initial operation of the bevel gear 98 and cam 147 engages the cam projection 151 with the bell crank 14:5 and permits operation of the clutch 123 to rotate the shaft 122 and swing thestapling devices away from the stapling position so that the basket may be withdrawn from the form without interference. The completed basket is then withdrawn from the form 6, such withdrawal being facilitated by the spring 69 pushing the plate 67 outwardly to strip the completed basket from the form, after which the completed basket is entirely removed and another basket shell placed in position on the cradle 77.
