EDWARD ERICKSON, OF BOEE'ICON, IVEASSACEUSETTS, ASSJGNOR TO THE BOYLSTON MANUFACTURING COMPANY, OF BOSTON,

new JERSEY.

Applieationfiled June 25, 1906, Serial no. 3231200. Renewed October 20, 1913.

To all whom it may concern Be it known that I, EDKVARD ERIGKSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful. Improvements in' ShoeSlugging Machines, of which the following, is a specification. I i

This invention relates to machines for inserting into thework a series of fasteners which are severed from a continuous strip of stock as fast as they are. driven. The form herein shown and described is adapted to that type of shoe machine known as slugger and with slight modification might be used for other classes of work in the manufacture of shoes. The object of the present invention is to provide a machine of the character referred to which will be capable of operating at high speed without detracting from eiiiciency and accuracy, and which will be simple and durable in construction and not liable to minor accidents.

in accomplishing these objects of the invention, I dispense with the complicated feeding mechanisms that have heretofore been employed, provide for the various operative parts being actuated with easy or graduated movements so as to prevent rocking of the machine, and employ simple mechanisms for securing the driving and severing of the fasteners and the feeding of the work.

in the embodiment of the invention which l have illustrated upon the drawings, the fasteners are formed from a metallic strip such as a piece of wire, and the-workis fed by laterally moving the embedded end of the strip, after which. said embedded end is severed; by cutters from the remainder of the strip. The driver takes the form of a" bar which is reciprocated and which is, mounted upon a laterally oscillatory head so" to have a lateral work-feeding movement at its strip-delivering end.

The driver bar has clamps or .ppers which interr .ntly

engage the stripto drive its end into the work, and in addition thereto has the cutters which are caused to sever the driven or embedded end of the strip.

In addition thereto, the machine shown is provided with a plate intervening"between the workand the fastener-inserting mechanism, andjagainst which the'face of the SHGE-SLUGGING MACHINE.

The I gage is held against the under surface of the plate 17 by a spring 25 and follower 26 contained in the bar 2 1 and pressing against the rear side thereof. 9 The bar is provided 2 means of the lever 29 the gage 22 may be adjusted in or out so that a heel held against.

it may be guided thereby in any desired relationship. to the fastener driving mechanism. Thehead 15, which, as previously stated is mounted upon and adapted to oscillate about the shaft 20, is held thereon by a cam disk 34 keyed to the end of the shaft. l

35 is a split driver bar which is adapted to be reciprocated longitudinally of its length and transversely of the axis of the shaft 20, and which is held in bearings 36, 36 on the head 15. I

37 is a stud affixed to one of the halves or the driver-bar and carrying a roll 38 which occupies a cam groove 39 in the disk 34:.

The contacting faces of both halves of the driver-bar are grooved along their median line, forming an orifice for the passage therethrough of a continuous strip 50, shown on the drawings as circular wire and suppliedfrom areel 51 on a bracket '52 attached to the standard 10. The strip 50 is driven successively step by step toward and into the work, is oscillated laterally to feed. the work, and the driven portion severed therefrom after having been moved'laterally to feed the work. In passing through the driver-bar the strip 50'engages successively a pair ofstraightemng dles 53, 53, a pair of grippers 54, 54 and a split driver 55 having a tubular delivery nozzle 56. (See Figs. 2 and 4:.) Of the dies 53, 53 one is aiiixed to one half of the driver-bar, and the other die is-movably installed between the halves and adapted to be adjusted by means of a set screw 58 threaded in the bar. v p The driver (see Figs. 4c. 5 and 7) comprises the member 55 havingthe delivery nozzle 56 and a separate removable member 59 loosely fitted uponlaterally extending dowels 4L0, 40. The confronting faces of the members 55 and59 are grooved for the receptionof the strip 50 and constitute gripping jaws by reason of having'teethi formed by a series of annular grooves 41..

The driver is installed in a chamber 155 formed in the driver-bar 35 and is actuated by means hereinafter described to grip the strip 50 during the downward movement and to release the strip during the upward movement of the bar. I

The head 15 is oscillated about the shaft 20 by-a lever 42 pivoted upon a stud 43 in a boss on the standard 10. One end of said lever is provided with a roll 1% which cooperates with a cam groove 4e5in the disk 34, and the other end of the lever is provided with a curved slot 46containing the head of an adjustable stud 47. One end of a link 48 is pivoted upon the stud afland the other end upon a stud 1-9 in the head 15, thus forming an adjustable connection between the lever and the head by which the head may be oscillated through an arc of any desired length. A flange 60 on the upper face of the plate 1'? occupies a peripheral groove 61 in the bottom of the head and serves to guide and brace the latter.

When the machine is at rest or in normal position the driverbar 35 is raised andthe head 15 isperpendicular as shown in Fig. 2. When the head is in this position the loose member 59 of the driver is forced toward the member 55 by a bar 62 movably installed in a laterally extending guide formed by protuberances 63, 63 on the bar 35. (See also Fig. 6.) One end of the bar 62 abuts against the member 59 and the other end abuts against a perpendicular face of a fixed bracket 64 extending from a standard 10. On the opposite side of the driver, an adjustable abutment 66 in the form of a set screw, and threaded in the head 15, acts through an intermediate block to brace the driver against the thrust of pressed by the cam 39, the bar 62 and block '65, which cause the driver members 55 and 59 to grlp the strip 50, slide relatively to the parallel faces of the bracket and setscrew without relinquishing their pressure upon the driver. The lower end of the driver-bar 35 in being depressed enters an orifice 67 formed in the plate 17 to allow it to approach closely to the work 100 on the 'ack. l

J The delivery nozzle56 of the driver projects slightly below the driver-bar so that when bothare depressed the end of the nozzle barely touches the work and if the end of the strip extends below the end of the nozzle it. is driven into the work. The cam39 is so formed that, after causing the driving of the end of the strip 50 into the work, it holds the driver bar motionless relatively to the head 15 for an instant during which the cam 15 causes the lever 42 to swing the head to the left, thus advanc ing the work, through the agency of the strip 50. Fig. 4 shows the head moved to the latter position. It will be observed that the bar 62 instead of moving laterally with the head is held by the bracket 64 whichhas a perpendicular groove 68 into which a roller 69 on the bar extends.

The chamber. 155' which contains the driver members is so formed as to permit a slight longitudinal movement of the latter therein for a purpose hereinafter explained, andwhen the bar 62 is in engagement with the driver it overlaps an inelinedsho'ulder 70 formed on the member 59 thus preventinga heel, the members 55and59 the driver from rising in the chamber during the driving of the strip 50. As shown in Fig.4, however,.the bar 62 is disengaged from'the member 59 to permit the seven ance of the driven fastener from the strip, to which the following description refers.

Each of vthe members comprising the driver-bar 35 has, an outwardly projecting circular boss 71 at the lower end, on Which.

is mounted each of two oscillatory cutters 72 having hardened steel cutting pins 78.

adapted to cooperate witheach other. (Figs. 2, 4,5 and 9). The cutting-edges of the members 72 are arranged on oppositesides of the line of the strip 50. When the driver bar 35 is depressed to drive thestrip into are depressed so that the lower end of the nozzle 56 may engage the stripe-as closely aS possible to the work for feeding. The cutters are provided with arms 74. which project from the driver-bar in opposite directions and which are adapted to abut against adjustable stopscrews 7 5 threaded inthelo'wer part of the head 15. previous to the oscillatingofthe head 15, the arms 74 of the cutters are moved" as closely as possible to the stop-screws 75 without actuallyengaging them. Then after the head hasbeen oscillated to feed the work, and the bar 62 withdrawn from the shoulder of the driver, a bulge 7 6 on the cam 39 depresses the driver-bar slightly farther. The effect of this last movement of the driver-baris to cause the cutters 72 to be oscillated upon their pivots by the stopscrews 75. This causes the cutting pins 73 to approach each other and severthe strip between them. formed and arranged as toeut squarely into the strip leaving thesevered portion blunt or square and compressing the new end of cutting pins in approaching each other engage the beveled extremity of the nozzle 56 and force it upwardly in its chamber 155 which is slightly elongated as previously stated. The cutters, by thus displacing the nozzle are enabled to cutentirel throu h and to cover the full cross of the strip. I strip, the cuttersarebeingdepressed about sectional area When the driver-bar is depressed The cutting edges are so,

During the cuttingof the three sixtyfourths of I an inch, the I shoeyielding to this extent, so'that the end of the slug is severed flush with the surface of the work. I

The'neXt movement of the driver-bar'35 isvupward, before the head 15 is oscillated back to its former position. The strip 50 is fed relatively to the driver by being gripped and held by the grippers 54, 54 hereinbefore mentioned, during the upward movement of the bar 85. I The said grippers are in the form of arms formed on rock-shafts-77,-7;7 mounted inbearings on the head 15. j The free'ends of the arms have roughenedeccen tric .faces which areadapted to engagethe opposite sides of the strip asalready stated. Actuating arms 78,78 are "pinnedto the outer ends of the rock-shafts 77, 77 and are normally heldapart by a spring ,79. The i 85 drawing an, additional supply through the.

dies 53, to replace the fastener previously severed. I Foroperatingsaid grippers,

The grippers therefore hold I employ the :following mechamsmi 8.0 is a plate havingbeveled ears or cams 8 1 Sl'on each sidetsee Fig. 2). The plate has slot 82 through which aTstud 83 extends and is screwed into the driver-bar clamping the plate thereto. The ears 8l, 81 are adapted to engage rolls-84, 84 at the free ends of the arms 78, 78' and force them together" against the pressure of the spring 79, thus) disengaging the gripper arms 54 from the, stripoO. The, plate 80 as, shown in Fig. 2a

is set at its highest position in which it does not engage the rolls 84, 84, but it may be clamped atany lowerposition by the stud 83. When clamped at a lower position the,

jears 81, 81 in descending engage and disthus holding the grippers out of engagement with the strip until place the rolls 84, .84

the rolls are released by the earson the up stroke of the latter. the up stroke when grippers in inoperative position, fthe straightening dies 58, 53 hold and carry the strip with them, but when the strip is caught by the released" grippers and held station During that. portion of ary it is drawn through the dies and fed 'relatively to the driver.

Upon the rompletionof. the up. stroke of the driver-bar, the head 15 is oscillated to the right, back its initial'p'osition shown 7 Thismovement causes t'hedriver to .appri'iachqand engage the inner end of in Fi O the bar62f it will be remembered that the cutters: during their operation raise the driver 55 relatively to the bar 62,so in case ihe-driver remains in that positionit isreturned to its lower'pfosition when theinner end of thesaidfbar engages the inclined the ears 81, 81' hold the I shoulder on the member 59-previous to feeding ofthe work in addition to the driving of the slugs or fasteners is accomplished.

The foregoin explanation covers the entire operation of the fastener driving mechanism, but, in describing the workfeeding mechanism the following explanation of the jack depressing mechanism is necessary. Referring to Figs. 1, 11, 12 and 13, is an'actuating cam aflixed upon the shaft 20 and cooperating with a roll 86 carried by a lever 37 fulcrumed uponv a stud 83 on the stazidardlO. The free end of the lever 87 is connected by a pin to the upper end of a vertically movable rod 891nounted in suitable hearings on the standard. The lower end of said rod extends loosely through ahole 91 in one end of a block and is provided with. a 'nut- 92 threaded thereon. d

93 is a rod extending parallel to and close to the rod 89 and having suitable bearings adapted to permit parallel movement thereof. The rod extends loosely through a hole 94- in the block 90 and is provided with a helical spring 95 compressed. between said block and the bearing 96. The rod 93 also extends loosely through a hole ,97 in a block 98 connected by a pin 99 to the other end of and extending underneath .the block 90. When in normal position the spring 95 pressing on the block 90 holds itagainst the block 98 and the latter against a fixed stop v 101. The lower end of the rod 93 ispivotally connected to cne end of a lever l02which is fulcrumed upon the'standard 10 by a stud 103. The other end of the lever extends between two lips 10 1,10 1 of a collar 105 se cured upon the jack 12. Afterthe driving of a fastener into the work, and prior to the lateral feeding of the work the cam 85 causes the lever 37 to raise the rod'89. The nut on said rod engages the under side of the block 90 and raises one end thereof, the other end being held down bythe spring Byreason of the loose fit of the rods in the holes 91 and 9a, the block 90 turns on the pin 99 and assumes an angle. as shown in F 1g. 11. This causesthe opposite edges of the hole 9% to take hold upon the rod 93 and continued upward movement. of the block causes it to move bodily and to carry the rod 93 with it. Theblock 98 has an car 106 which is connected by a spring 107 to a fixed member 108 below it, and as the block 90 rises bodily, raising the pivoted end of the block 93, the downward tension of said spring causes the latter block to assume an angle relatively to the rod 93. The opposite edges of the hole 97 then take hold upon the'rod 93 and during the remainder of the upward movement of the rod 89, the blocks 90 and 9S and the rod 93 move therewith as a unit. The movement thus given to the rod 93 is transmitted to the lever 102 which depresses the jack against the pressure of the spring 14. The jack is held in the lower position by the cam thus relieving the pressure of the work against the plate 17 while the cam 15 actuates the head '15 to feed the work. It is while the jack is unlocked'that the cutters sever the driven slug. When the blocks 90 and 98 are returned to normal position by the spring 95, the holes 94 and 97 become alined so that the rod 93 may slide relatively thereto when the jack is depressed by means of the treadle 18. Power for rotating the shaft 20 is applied to pulley 110 loosely mountedon the rear end of the shaft. Said pulley normally rotates idly about-the shaftbut has a plate 111 containa ing one or more holes 112 which is adapted to engage a bolt 113 contained in a casing 114: mounted upon and attached to the shaft.

A spring 115 tends to force the bolt into operative engagement with the pulley but it is normally held out of engagement therewith by a wedge shaped flange 116 formed on a block 117 pinned to one end of a plunger 118. Said plunger is adapted to slide in a bracket 119 on the standard 10 and its other end is connected by a rod 120 to a lever 121 fulcrumed upon the stud 19 upon which the treadle 18is also fulcrumed. The

flange 116 is normally held in engagement with a nose 122 on the bolt by a spring 123 i of which one end is attached to the standard and the other to a collar 124 on the rod 120.

The rear end ofa treadle 125 fulcrumed upon a pm 126 underlies the free end of the lever 121. and. when depressed it rocks .127 and 128, 128. The rotation of the casingtransmitted from the pulley by the bolt is in turn transmitted through rubber blocks to the collar 129 and thence to the shaft 20. The blocks serve to absorb the sudden shock of starting the shaft and continue to rotate the same as long as the flange 116 is held out ofthe path of rotation of the nose 122.

131 is a flange formed on the periphery of the casing 114- and adapted to engage a roll 132 mounted on a lug projecting from the block 117. Said fiangeis adapted to keep the block and flange nut of the path of rotation of'the nose 122 when the treadle 125 is released, eXcept when a depression 133 arrives opposite the roll and permits it to approach the casing 11%. When the roll does enter into the depession the flange 116 moves into the path of the nose 122 and the latter engages and is deflected thereby,Withlrai V he-bolt from. the plate 111 and rendering the machine idle, The momentum of the machine isarrested ivhen the block 11 approaches the casing by a brake-shoe 13% carried by said block. Said brake-shoe is mounted upon a lug 135 projecting from the block and engages a liange 188 forms on the periphery of casing.
