24 claims. (ci. 10o- 31) This invention relates to bundling machines and is particularly adaptable for binding together stacked substantially at strips.

The primary objects of my invention are to pass binding means, which may be in the form of wires or the like, about a bundle of stacked substantially flat strips near the ends of the bundle, and to secure the binding means on the bundle.

Another object is to so position binding means in the machine that a bundle of stacked substantially flat strips may be engaged therewith and moved relative thereto to withdraw the binding means from supplies thereof in the machine and thereby pass the binding means about the bundle near the ends of the bundle.

Further objects are to sever the binding means after passage thereof about a bundle; to interconnect the severed ends and secure the binding means on the bundle; and to arrange the binding means for engagement with another bundle subsequently positioned in the machine.

Still further objects are to provide separable jaws for severing, securing and positioning the binding means; to close and open the jaws automatically in the operation of the machine; to intertwist the ends of the binding means, when in the form of wires, by devices in the separable jaws; to so time the operation of the various devices in the machine that efficient operation is assured; and to provide a novel machine of simple and positive operation and economical construction.

Fig. 12 is a fragmentary vertical sectional detail view taken substantially cn the line I2-I2 on Fig. 1; and

Fig. 13 is a detail view of the main clutch and the operating parts therefor.

In the selected embodiment ofl myginv'entlon illustrated in the accompanying drawings I4v indicates a suitable frame for the machine and supporting a plate I5 at the top thereof. Aligned bearings I6 and I1 are mounted on the plate .I5 5 adjacent the rear edge thereof and the main drive shaft I8 is journaled in these bearings. A

flywheel I9, about which a belt or the like may be directed to transmit power from a suitable source, such as anelectric motor, to the flywheel, 10 is rotatably mounted on the shaft I8 adjacent one end thereof, a collar 2l! being fast on the shaft to prevent movement of the flywheel toward said end of the shaft. A main clutch is mounted on the shaft I8 intermediate the adja- 15 cent bearing I1 and the flywheel I9 and includes a driving p-art 2l rotatable on the shaft I8 and connected to the flywheel I 8 and a driven part 22 fast on the shaft I8.

A pinion 23 is fast on the drive shaft I8 at 20 the side of the bearing opposite `the main clutch and this pinion meshes with a gear 24 fast on the cam shaft 25 journaled in bearings 26 and 21 carried by the plate I 5. The control and timing de' vices for the machine are mounted on the cam 25 shaft 25 as will be described hereinafter.-

The main clutch includes a control dog 28 (Figs. 3 and 13) regulated by the arm 29 of the rocker 30 mounted on the shaft 3| journaled in'a bracket 32 (Fig. 5) fast to the side of the bearing I'I. A 30 link 33 is connected tothe free end of the arm 34 of the rocker 30 and to a foot treadle 35 pivotally mounted in the frame I4, as indicated at 36. The foot treadle extends to the forward end of the machine from the pivotal mounting 36 35 thereof and the link 33 is connected to the foot treadle rearwardly of the pivotal mounting 36. A link 31 is connected to the foot treadle 35, near the forward end thereof, and to one end of a spring 38, the opposite end of said spring being secured to a spring anchor 39\ depending from the plate I5. The spring 38 normally urges the forward end of the foot treadle 35 upwardly and the rear end thereof downwardly and therefore the link 33 normally holds the arm 29 ofA the 45 rocker 38 in the position illustrated in Fig. 13 whereat the dog 28 is engageable with the arm 29 to effect disengagement .of the main clutch.

A cycle of operation of the machine, as illustrated, ventails four revolutions of the shaft I8 50 and to this end means are provided for retaining the arm 28 out of dog engaging position until a cycle of operation is finished and this means includes a peripheral cam 38'` fast on the camshaft 25 in substantially vertical alignment with the 55 main clutch. 4 A roller 3|' on the depending arm 32' of the rocker 30 is urged into engagement with the peripheral cam 30 by the action of the spring 38. Thus when the forward 'end of the foot treadle 35 is depressed and the arm 29 is retracted from engagement with the dog 28 a spring 40 in the-main clutch acts on the dog to effect engagement of the driving and driven parts 2l and 22 of the main clutch whereupon the shafts I8 and 25 are set in operation. The forward end of the foot treadle 35 is manually held in depressed position until a rise on the cam 30 engages the roller 3l which occurs immediately after the start of rotation of the shaft' 25, and after the rise on the cam 80' has engaged the roller 3I' the forward end of the foot treadle 35 is held in depressed position. The engagement of the rise on the cam 30' with the roller 3 I holds the arm 29 out of dog engaging position and the roller 3|' remains in engagement with the rise on the cam 30 until immediately prior to the time the shaft I8 has completed its fourth revolution whereupon the roller 3|' moves onto a drop in the cam 30 andthe spring 38 repositions the arm 29 in dog engaging position so that-the main clutch is disengaged at the end of the fourth revolution of the shaft I8. The ratio between the shafts I8 and 25 is four to one so that the cam shaft 25 makes but a single revolution while the drive shaft is making four revolutions.

Brackets 4I and 42 are mounted on the plate I5 `in side by side relation near the front edge thereof. A horizontal work table 43 is supported by the brackets 4I and 42 above the plate I5.and at the front of the machine. The Work table 43 has/a medially located slot 44 extending longitudinally thereacross and this table is equipped with side flanges 45 and 46. A transfer carriage C smounted on the table 43 between the side flanges 45 and 46 and includes an angle plate 41 having a medially located depending lug 48 thereon which isdisposed in the slot 44. A strip 49 is secured to the lug 48 and engages the bottom of the table 43 and retains the lug in the slot 44 so that the carriage is supported for sliding movement over the horizontal table 43. A clamp plate 50 is carried by the arms 5I -pivotally mounted as indicated at 52 in the upstanding part of the angleplate 41 and a hand-plate 53 is fast on the arm 5I. The hand plate 53 may be manually grasped so that the clamp plate 50 may be pivoted upwardly to permit abundle B of stacked substantially flat strips to be positioned therebelow, said bundle being rested on the table 43 and engaged with the front face of the upstanding part of the angle strip 41.

When the hand plate 53 is grasped and pressure is applied thereon the clamp plate 50 is urged into engagement with the top of the bundle B and then by applying further pressure on the hand plate 53 the transfer carriage C may be moved across the horizontal table 43, the side anges 45 and 46 of said table guiding the ends of the strips in the bundle. riage C is so moved across the table 43 the bundle of strips is moved from the forward end of the table into bundling position near the rear edge` of the table and indicated by B'.

The illustrated embodiment of the invention is particularly adaptable for bundling strips of expanded metal such as are often incorporated in railway brake shoes. Y These strips of expanded metal are in the form of substantially flat strips and are stacked one upon the other and wires are passed about the stacked strips near the ends When the transfer carthereof.

thereof to bind the strips together and prevent displacement thereof during casting of the brake shoe. The Wires so passed about the bundle also serve to support the bundle in the mold cavity to the machine is used for bundling strips of expanded metal, wires are used as the binding means and these wires are preferably withdrawn from supply spools supported in proper position on the brackets 4I and 42.

Four spools of wire are provided, two of which are supported above the horizontal work table 43 and the other two of which are supported below said table so that wire lengths withdrawn from the spools may be respectively passed across the top and bottom of the bundle near the ends thereof. ,Upstanding'arms 54 and 55 are respectively provided on the brackets 4I and 42 and spindles 56 and 51 are respectively mounted in these arms. Spools of Wire 58 and 59 are rotatably mounted on these spindles above the work table 43. A spindle 60 is mounted in the bracket 4I below the work table 43 and substantially in vertical alignment with the spindle 56 and a spool of, wire 6I is rotatably mounted on this spindle below the table 43. Another spindle 62 is mounted in the bracket 42 in horizontal alignment with the spindle '68 and substantially in vertical alignment with the spindle 51 and a spool of wire 63 is mounted on this spindle 62 below the table 43.

A length of wire 64 is withdrawn from the spool 58 and is directed to a grooved guide pulley 65 (Fig. 9) ,rotatably mounted in the bracket 4I above the work table 43. A length of wire 66 is withdrawn from the spool 6I and is directed about a grooved guide pulley 61 mounted in the bracket 4I in vertical alignment with the guide pulley 65 and below the table 43. A length of wire 68 is Withdrawn from the spool 59 and is directed about a grooved guide pulley arranged in horizontal alignment with the guide pulley and a length of wire 69 is withdrawn from the spool 63 and is directed about a grooved guide pulley horizontally aligned with the guide pulley 61. At the start of the operation of the machine the ends of the wire lengths 64 and 66 are twisted together and the wire lengths are disposed in a position substantially like that illustrated in broken lines in Fig. 9 and the wire lengths 68 and 69 are similarly arranged.

'I'he intertwisted ends of the wire lengths and the positioning thereof as described so locates the wire lengths that when the bundle B is slid forwardly from its initial position with the transfer carriage C the leading edge of the bundle engages the Wire lengths, which are disposed near the ends of the bundles and continued movement of the transfer carriage withdraws wire from the spools so that when the bundle attains the position B lengths of wire extend across the top and bottom of the bundle near the ends A stop 10 is mounted on the underside of the work table 43 and is engaged by the lug 48 to interrupt movement of the transfer carriage over the work table to limit movement of the transfer carriage and insure positioning of the bundle in the position B. After the bundle is in the position B', the transfer carriage C is retracted to its initial position."

When the ends of the wire lengths are ar ranged as shown in broken lines in Fig. 9 they 4 are disposed at one side of the severing. securing and positioning jaws of the machine but whenv the bundle attains` the position' B' the bundle will have passed through the separated severing, securing and positioning vjaws and the wire lengths will be drawn past these separated jaws.

Two severing, securing and positioning jaws are provided in the machine, each ofwhich is adapted to cooperate with the binding means at an end of the bundle. These jaws are respectively supported on shafts 1| and 12. The shaft 1| is journaled in a bearing 13 on the bracket 4| and in a bearing 14 carried by the plate I5.. The shaft 12 is journaled in a bearing 15 on the bracket 42 and in a bearing 16 carried by the plate I5. The bearings 14 and 16 are preferably arranged in transverse alignment with the bearing i6, as best illustrated in Fig. 1.

The jaws are identical -in construction except that they face toward each other, that is, the separated parts thereof face each other when the jaws are in open position. The jaws separate along parting lines that are disposed sube stantially horizontally when the jaws are closed. In each of the jaws there is a gear divided into equal halves and when the jaws are separated one gear half is located inthe upper part of each jaw and the other gear half is located in the lower part of each jaw. When, however, the jaws are closed the gearohalves are united -to provide' a continuous gear and parts of the jaw unite to provide gibs on which the gears are supported for rotation.

The upper half of each jaw includes an arm I'I having a recess 18 in one face thereof. The upper half of the gear in each jaw is mounted in this recess and has a groove in one face thereof in which a rib 8| in the recess 18 is fitted.-

A plate 82 is fast to each arm 11 and respectively closes the recesses 18 to enclose the gear half in the recess. Each plate has a rib 83 thereon that extends into a groove 84 in the face of each gear half and located opposite the groove 80 therein. A hardened member 85 is mounted on the inner periphery of each gear half 19 and includes a diametrically extending edge in which there are grooves 86 and 81. A severing jaw 88 is located between the grooves and clamping ribs 86 and 81' are provided at the outer edges of the grooves. As best illustrated in Fig. 6, the arm 11 of one of'the jaws is pivotally mounted on the shaft 1I and, as best illustrated in Fig. 7, the arm 11 of the other of the jaws is pivotally mounted on the shaft 12. Each of the arms 11 includes a lug 11 formed as a continuation thereof which extends from the shaft opposite the extent of the respective arms.

The lower half of each of the jaws includes an arm 89. One arm 89 is pivotally mounted on the shaft 1| and the other arm 89 is pivotally mounted on the shaft 12, as illustrated in Figs. 6 and '7. Each arm 89 has a recess 90 in one face thereof in which a gear half 9| (Fig. 11) is mounted. Each gear half 9| has a groove 92 therein in which a Arib 93 in the respective re- `cesses is mounted. A plate 94 is secured to one face of each arm to close the recess 90 therein and enclose the gear half 9|. Each plate 94 has a rib 96 thereon which extends into a groove 91 in the gear half 9| opposite the'groove 92. A hardened member 98 is mounted on the inner periphery of each gear half 9| and has a diametrical edge in which grooves 99 and. |00 are provided. A severing jaw |0I, adapted for cooperationwith the severing jaw 88, is located between the grooves 99 and |00 and clamping ribs 99' and |00 are provided at the outer edge of the grooves 99 and |00.

When the jaws are closed the ribs 8| and 96 unite to provide aigib as do the ribs 83 and 93. Further, the diametrical edges of the hardened members 85 and 98 interengage, the severing jaw ISI passing into the groove 81 and the severing jaw 88 passing into the groove 99. The clamping rib 99 passes into the groove 86 and the clamping rib 81' passes into the groove |00 when these edges engage. Thus the gears are united when the jaws are closed and are rotatably supported on continuous gibs.

The jaws are closed and opened automatically in each cycle of operation of the machine, the jaws normally 'being in open position, as illustrated in Fig. 8. The opening and closlng'of the jaws is controlled by a peripheral cam I|2 fast on the cam shaft 25 adjacent the bearing 26. An arm |I4 fast on the rock shaft |04 carries a roller ||3 that rides on the peripheral cam I2. The rock shaft |04 is journaled in bearings |02 and |03 depending from the plate I5. Arms |05 and |06 are fast on the rock shaft |04 adjacent` the bearings |02 and |03 and, as best illustrated in Fig. 5, these arms are bifurcated at their free ends to receive a pin |01. A link |08 is connected to the pin |01 in the bifurcation in the arm |06 and a link |09 is connected to the pin |01 in the bifurcation in the arm |05. A toggle is provided at the upper end of the links |08 and |09 and these toggles comprise links I I0 and I I I. The links |I0 are pivotally connectedto the free ends of the lugs 11 and the links I I are respectively connected to the arms 89. Springs |28 act on the arms |05 and |06 to urge the blfurl cated ends of these arms downwardly and to maintain the roller ||3 in engagement with the cam I|2 and the springs |28 therefore act through the links |08 and |09 and the respective links |I0 and III to normally hold the jaws in the open' position illustrated in Fig. 8. When, however, a rise on the cam I I2 engages the roller II3 the bifurcated ends o f the arms |05 and |06 are pivoted upwardly against the action of the springs |28 and the links |08 and |09 are moved upwardly and straighten the toggles provided by the links I|0 and ||I. Upward movement imparted to the links III urges the arms 89 of the lower halves of the jaws upwardly and upward movement of the links |I0 acts through the lugs 11' to urge the arms 11 of the upper halves of the jaws downwardly and thus upward movement of the links |08 and |09 closes the jaws.

The driving part ||2 of an auxiliary clutch (Fig. 12) is keyed to the shaft I8 adjacent the pinion 23 and the driven part H3' of this clutch is `rotatably mounted on the shaft I8 intermediate the driving part I2 and the bearing I6. A gear |I4 is keyed to a hub of the driven part I3'. The gear II4' meshespwith gears |24 and |25 respectively fast to the shafts 1| and 12. A pinion |26 is fast to the shaft 1I adjacent the arm 11l thereon and this pinion |26 meshes with the gear formed by the gear halves when the jaw on the shaft 1I is closed. A pinion |21 fast on the shaft 12 adjacent the arm 11 on this shaft meshes with the gear provided by the gear halves on the jaw on the shaft 12 when the jaw on this shaft is closed.

When the auxiliary clutch is engaged the gear III rotates with the shaft i and this movement is imparted through the gears |24 'and |25 to the shafts 1| and 12 and thence through the pinlons and |21 to the gears in the jaws.

The auxiliary. clutch is controlled by a peripheral cam |22 fast on the cam shaft 25 intermediate the cam ||2 and the gear 20. 'Ihe auxiliary clutch includes a control dog ||0 (Fig. 4) regulated by the arm '||0- of a rocker ||1 pivotally mounted on the shaft 0 carried by the bracket III' (Fig. 1) fasttothe bearing I.. Aspring Il!4 acts on the rockerl ||1 to urge the arm III into dog ,engaging position illustrated in Fig. 4. An arm |2| is pivotally supported in the frame il and carries a roller `|22 that travels on the cam" |22. A link |20 interconnects the arms ||0 and |2| and when the roller 22 engag a rise on the cam |22 the arm |2| is pivoted downwardly and the link |20 withdraws the arm ||0 from dog engaging position whereupon the driving and driven parts ||2' and ||2 .of the auxiliary clutch are engaged and the gear ill' is set in operation.

At the start of an-operation of the machine the severing, securing and positioning jaws are in open position and the transfer carriage C is in initial position at the forward end of the work table 42 and the wire lengths leading from the supply spools are positioned as sho\A in broken line's in Fig. 9. The operator of the machine then arranges a bundle of expanded metal in the transfer carriage C and then moves the carriage .e

over the work table and the leading edge of the bundle engages the wire lengths and continued movement of the bundle toward tbe position B' draws the wire lengths over the top 'and bottom of the bundle and through the separated jaws, and when the lug 40 engages the stop 'I0 the bundle is arranged in the position B. as shown in Eig. 9.

The operatorthen depresses the forward end of the treadle 25 engaging the main clutch whereupon the shaft I0 is set in operation. The cam holds the arm 20 out of dog engaging position and the cam shaft 25 rotates with the shaft I0. Preferably the ratio between the shaft I0 and the cam shaft 25 is foin' to one so that the cam shaft 25 will make one revolution while the shaft i8 is making :our revolutions. During the first one-eighth of a revolution of the cam shaft 25 the rise on the cam ||2 engages the roller ||2 whereupon the links |00 and |00 are moved upwardly and at the completion of one-eighth of a revolution of the cam shaft 25 the severing, securing and positioning jaws are closed. At the end of this one-eighth of a revolution of the cam shaft 25 the rise on the cam |22 will have engaged the roller |22 so that at this time the arm ||6 will have been retracted from dog engaging position and the auxiliary clutch will at this time be engaged, setting the shafts 1| and 12 in operation. The shafts 1| and 12 continue to rotate until the cam shaft 25 has completed seveneighths of its revolution whereupon the roller |22 will have engaged a drop in the cam |22, and the spring ||9 will have positioned the arm ||6 in dog emaging position to disengage the driven and drivingparts of the auxiliary clutch to interrupt further rotation of theshafts 1| and 12 at this time. During the remaining one-eighth of a revolution of the cam shaft 25, the roller ||2 will move onto a drop in the cam ||2 and the springs |28 will therefore move the links |08 and |09 downwardly, which movement will be transmitted through the links ||0 and ||I to bundle moved with the transfer carriage from envases open the jaws. During this same period theroller 2|' will move onto a drop in the cam 20' anda l spring 2 0 will move the forward end of the foot treadle 25 upwardly to reposition the arm 20 in dog engaging position so that as'the main drive 5" shaft |0 completes its fourth revolution and the cam shaft 25 finishes its single revolution the main clutch will be disengaged and operation of the machine interrupted. 'Ihus it will be seen that the main drive shaft |0 makes four revolutions, the cam shaft 2l makes one revolution, and since the auxiliary clutch remains' closed for three-fourths of a revolution of the cam shaft 20 the shafts 1| and 12 will make three revolutions during each cycle of operation of the machine.

'I'he free edges oi.' the severing Jaws 00 and |0| are the first parts to move into cooperating relation when the jaw halves are moved toward each other and these severing Jaws cut the wire lengths. Immediately following the cutting of m the' wire lengths the clamping ribs 00' y,move into the grooves 06 and the clamping ribs 01' move into the grooves |00. Thus the marginal ends of the wire lengths on each side of the cut are clampedin the grooves by the clamping ribs when the I1aws are completely closed, as illustrated in Fig. 10. Therefore, the ends of the wire lengths are heldin the hardened members 05 and 00 and as these members are carried by the gear parts which at this time will be united into continuous 30 gears and as these continuous gears mesh with the pinions |20 and |21 and as these pinions |20 and |21 will rotate with the shafts 1| and 12 and as the ratio between the gears provided by the united gear parts and the pinions-.I20 and |21 is one to one the united gear parts will rotate three times which will effectively twist the wire ends on each side of the jaws. The wire ends extending from the bundle in the position B will be'drawn tightly about the bundle by this twisting so that the strips in the bundle are firmly bound together. The'wire lengths on the other sides of the jaws are intertwisted together and are positioned to be engageable by the next the forward end of the work table into the position B and after the next or subsequent bundle has been moved into the position B' the forward end of the foot treadle 25 is again depressed and the foregoing operations are repeated.

It is manifest from the foregoing description that my novel machine may be employed for binding a bundle of substantially flat strips, such as strips of expanded metal, which are arranged in side by side relation as by being stacked one upon the other. The machine as constructed passes binding means about the bundle near the ends thereof and when wires are used as the binding means the machine intertwists the ends of the wires so as to tightly bind the strips in the bundle together. If binding means other than wire is used as, forexample, when cord or the like should be employed, the divided gears described may be used to drive a motor or similar device for securing the ends of the binding means. In the machine the binding means is supported so that when the bundle is moved into engagement therewith and relative thereto the binding means is withdrawn from supplies thereof in the machine and passed about the bundle. Furthermore, the machine supports the binding means for engagement with the bundle and severs the binding means from supplies thereof and retains the severed means with bundles successively passed into the machine.
