invention relates to fastening forming and inserting machines and is illustrated herein as embodied in a rnachineiorsevering and inserting wire slugs in the bottoms of boots and shoes of 5 the type disclosed in United States Letters Patent No. 786,190, granted March 28, 1905, on an application filed in the narneof Louis A. Casgrain.

Machines of the type referred to above have been successfully used for many years. In actual use, however, it was found that fastenings under some conditions might not be fully expelled from the severing and transferring die which cuts on the fastenings and transfers them to driving position or the driver might break,

. driver might projectbeyondthe end of the die.

Under such conditions parts of the machine might be broken or injured during return movement of the (hate fastening receiving position;

-Acc'ordingiy, byan invention of W. I. B. Roberts disclosed inUnited States Letters Patent No.- 1,651,469, granted Dec. 6, 1927, provision was made for stopping the feed offthe wire if an improperly inserted fastening or a broken driver projected beyond the endof' the fastening sever- 1 ing. and transferring die during movement of the die-to fastening receivingposition.

The present invention provides a still further improved organization of the type referred to.

In accordance with the present-invention as herein illustrated there is provided in the mechanism which feeds wire to a fastening severing and transferring member a cooperating member constructed and arrangedto be uniailingly'detached,

11 thereby" interrupting the feed whenever even slight resistanceto the return movement of the fastening severingxand transferringmember is encountered; As illustrated, the machine is pro! vided with a feed wheel and a presser roll arranged to be held against the feed wheel by spring pressure... Pressure of the spring istransmitted to the presser roll through an arm and a rod which are held together by a hook connection arranged tobe'disengaged when a broken driver or projecting slug strikes a sliding block which are-disengaged .the'presser roll drops away from the ifeedwheel and remains inthat position until the arm and rod are again connected manually. These and other features of the invention will appear more :iully fronithefollowing detailed descriptionwhen read. in connection with the accompanying drawing and will be pointed outin.

the appended claims.

In .the drawing,

with the result 'that the fastenings or broken- Fig. l is a view in front elevation of a fastening inserting machine embodying the present invention; Fig. 2 is a view in front elevation on a larger scale of the wire feeding and wire severing mechanism; l Fig. 3 is a plan View on an enlarged scale of the presser plate; and i V Fig. 4 is a sectional View taken along the line IV-IV of Fig. '3.

The illustrated machine is provided with a head 12 mounted on a column l0. A' shaft 14 is mounted in suitable bearings in the head of the machine-and carries cams which are arranged to actuate the operating instrumentalities .of the machine. Wirefeeding mechanism is situated at the left-hand side of the machine as'viewed from the front. The Wire passes from a suitable source of supply to a Wire feed wheel 56 which is rotatably mounted on a shaft IS in a bracket ii. peripheral face of the feed wheel is is provided with ratchet teeth engaged by pawls it carried by an arm 2Dwhich is oscillated by connections .in eluding a. link 22 and a cam member 2 8 to rotate the feed wheel 46 in the manner disclosed in the above-mentioned Letters Patent No..l,651,469.

The wire is held against the feed wheel 16 by a. presser roll 26 which is rotatably mounted by a pin 28 on an arm 30 pivoted at 32 to the bracket IT. The roll 25 is held against the feed wheel it by a rod formed in two parts 34, 36. The upper part 34 of the rod, as viewed in Figs. 1 and 2, is provided with a notch or recess 38 which, in the normal operation of the machine, receives a book 40 formed on theupper end of the lower part 36. The lower part 35 is in the form of a short arm" loosely pivoted on the front end of the pin 28 on which the presser roll 26 is mounted. The short lower arm 36 extends upwardly from its pivot close'to the left-hand side of the rod 34 and has the hook 441 formed on its upper end. In the normal operation of the machine a spring 52 surrounding the upper end of therod 34 acts through the two parts 34, 36 of the rod which are connected together by the hook 411 on the lower part 38 and the notch 38 in the upper part 34 to hold the presser roll 28 against the wire and the wire against the wire feed roll I6. It is to be noted that the rod 34 is slidably mounted in a boss 13 formed in the bracket 1| 1. The lower end of the spring AZbearsagainstthe boss 43 and the upper end of the spring 42 bears against a wing nut 45 threaded. to thaupper end of the rod 34. The tension of the spring 42 may be varied by turning thetwing nut .45. ;Ifthe short arm 3 is swung PATENT critics r partd l'of the rod and the presser roll 26 can then drop away from the wire feed wheel l6, thus releasing pressure on the wire to stop the feed of the wire; Inorder :to-movethe short lower arm 36 in a counterclockwise directiom there is pivotally connected to the short arm 36 at its upper has a block 46 secured to its right-hand end... I

The block 46is slidably mounted inhori'zontad I guide-ways 5!] extending from left to rig'htof the machine formed in a presser-plate48 se'cured to the head of the machine.

and the driver-'1 56 pass in their work feeding and slug driving. operations; The right-hand end of the block 46 is located just to the left of -the path of movement of the driver and the lower face of l q the block is level with. the lower surface. of the plate48. Bivotal connection between thebar 44 and the short lower arm 36 is such as to allow; the bar 44 to move horizontally whilec-th'e arm;36 swings about its pivot. i

Inthe event that a .slug or broken; end of a driver projects beyond the outer end of arotatable shearing and transferring; die58 when the latter is rotated irra clockwise direction frorn a vertical slug driving position to -a;horizonta1 wire receiving position", the projecting slug or driver will engage'the-right-hand end of the block. 46 and will move the-bar Mto the left. The hook-4i] will beswung outjofe'ngagement with the notch 38 formed infthe upper part 3 10f the rod and allow the presser roll 26 to swing'downwardly away from the wire feeding roll I6 intothe position shown inFig-.:2. The feeding of the wire isthus stopped during subsequent cycles of the ma.-

chineuntilthe slug or broken driver hasbeen 're-J moved and the hook .onthe'upper end of the short arm 36 has been replaced'into the notch" 38 in the upper part 340i the rod.

The .guidewaysiflfare formed in each wall of an open-ended slot52 formed in the plate 48 through which the awl 54 wire receiving position of the die, to its slug driving position the arcuate face 166fprevents the slug from being thrown out of the shearing and transferring die 58. itsslug driving position the slug can drop on to the surface of the work piece into which it is to be driven. j Y V I illustrated embodiment of the invention there is provided a small plate-68 as shown in Fig\ out of or partly out of the right-handendof the die 58 as a result of the shearing action andthe'reby interfering with the action of the driver. The plate'68 is'position'ed when the cover is closed just to the right of the end of the shearing and transferring die 58 when the die 58 is in its. wire receiving position, as shown in Fig. l, andprevents a cut off slug from passing through the slug receiving opening in the die 58 owing to the shearing actionyof the dies onthe wire. The presence of the block lfi in the open end of the slot 52 inithe presser plate 48 against which the workis held considerably reduces the. length of the slot 52,. 1 The right-hand end of the block 48 is normally close to the path of movement .of the driver and the' slot is only just long enough to permit the awl 54 to enter and feed the work when the awl actuating mechanism is adjusted to give it its maximum feeding movement.v The slot is,-

irithis wa as small as possible and objectionable marking of the surface of the work into. which vIt may be wellat this point, for a moreclear unthe mechanism for rotating the fastening shearing and transferring die 58. The variousparts of this mechanism willnot be described in detail since they areiclearly and fully described in the above-mentioned Letters Patent No. '1,651,469 to which reference may be had'for a more complete disclosure of the construction and operation of these parts. The shearing die 58 is mounted on a shaft 18, shown in dotted lines in Figs. 1 and 2, towhich is secured an arm 86. The'arm is pivotally connectedat 82 to thelower end of a link 84,the upper 'endof which encircles an eccentric 86 on a horizontal shaft 88 rotatably mounted in bearingSfOhv the .frame above and parallel to the shaft [8. Fixed-on' th'e shaft 88 at each side of the eccentric 86 are two pinions 90 which mesh. with gear segments 96 formed on a cam lever 98- pivoted at I02 to the frame. The cam lever 98 When the die 58 reaches derstan ding'of the invention, to describe briefly has a cam roll Hi6v which enters a cam groove I08 formedin a cam l 10 fixed on the main shaft M of the machine. By this mechanism the shaft 18 is-moved through90 to shear the, wire and carry the severed slug to driving position and, since it isimportant that the die shall be accurately locatedboth in its horizontal position in' which it'receives the wire andinjits vertical:

position in which the driver passes throughthe: passage in the die to drivethe slug, the mecha-' 2 nismis so arranged that the center]! 'IZ of the ec-" centric 86, the axis of the shaft 88 on which it is fixed, and the pivotal point BZ on'the lower end of'the'eccentric linkr8e' are substantially in line at each limitingposition of thedie. 'By this meansany slackness between the .teeth of the segments and the pinions'has-very little, if any,

effect upon the position of the die. I

To relieve the teeth of the segments and gears of strain during the shearing ofthe'wire a cam lever H6 is rotatably mounted on the die carrying shaft I8 and this cam lever has a roll H8 which enters a cam groove 623 formed on a cam fixed on the main shaft I4 of the machine. The cam lever I 16 has formed on it a lug I22 which engages a lug I24 formed on the arm 86 which, as stated, is fixed on the shaft I8. The cam tracks I08, I20 are so formed that during the shearing. the die shaft 18 is driven by bothcams but the strain due to the shearing istaken by the second cam lever II6 through the engaging faces of the lugs I22, I24-and after the shearing of the wire these faces are disengaged and the shaft 78 is moved to the position in which the slug is driven by the first cam Hi3 through the segments 96 and the pinions 94. The cam roll I I8 on the cam lever II 6 is mounted on an eccentric stud fixed on the lever so that the roll may be adjusted properly to position the face of the lug I22 on the lever in relation to the face of the lug I24 on the arm 80.

I In order to enable the operator to hold and position small work pieces such as a top lift on a highheel having a very small tread face, the plate 43 against which the work is pressed is cut awayand rounded at its front left-hand corner in front of the open ended slot and plate and, to prevent the forward end of the plate from bending upwardly under the pressure of the work against it, its right-hand side is thickened somewhat and its left-hand corner is supported against upward pressure by a rod I39 which is com veniently an extension of the'pivot of the cover It. The operator is thus enabled conveniently to pass the fingers of his left hand beneath the plate 48 and hold, for example, a small top lift on its heel to which it; is to be fastened by slugs driven through it. 7 i

The operation of the mechanism for preventing feeding movement of the wire will now be briefly described. When the fastening receiving memberor die 58 is in the position shown in Fig. 2 and a broken driver or improperly inserted slug projects from the lower end'thereof the die 58 is in aposition to, be moved in a clockwise direction tothe position shown in Fig. 1. When the broken driver or improperly inserted slug strikes the block 46 the block is moved to the left. The

;; short lower arm 35, which is connected to the block M3, by the bar 44, is swung in a counterclockwise direction to move the hook M3 on the arm 35 out of engagement with the recess 38 in the upper part 34 of the rod. The presser roll tfi'is then permitted to swing downwardly away from the feed wheel I6. Pressure on the wire against the feed wheel is released and further feed of the wire is prevented until the hook 40 on the arm 36 is again engaged with the recombination, a fastening receiving member, a

feed wheel, a member arranged normally to cooperate with said feed wheel to feed fastenings to said fastening receiving member, a fastening inserting tool, and detachable means constructed and. arranged'to maintain said secondmentioned member normally in operative relation to said feed wheel, said means being constructed and arranged, upon failure of said tool properly to insert a fastening, to be rendered inoperative to disconnect said second-mentioned member.
