Application filed January 25, 1911. Serial No. 604,597.

To'aZZ whom it may concern Be it known that I, HERBERT W. KEN- wAY, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Machines for Setting Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for setting fasteners in sheet material and more particularly to machines for setting lacing hooks in the uppers of boots andshoes, although certain features of the invention may be advantageously embodied in machines for setting eyelets, studs or other similar articles.

An object of the invention is to simplify the construction and improve the operation of hook setting machines as heretofore constructed.

`To this end an important feature of the invention consists in so organizingthe various instrumentalities of a hook setting machine that a straight raceway may be employed for delivering the hooks from the hopper or magazine to the setting devices. By eliminating all turns and branches from the raceway the possibility of a hookbecoming misplaced so as to form an obstruction in traversing the raceway is obviated. The straight raceway has also an important advantage from the manufacturing standpoint in that it may be produced easily and accurately and at relatively low costi In the machine hereindisclosed, the raceway is linclined sufliciently to insure the hooks sliding'by gravity to its lower end and a hook carrier is disposed in substantial alinement with said raceway so that successive hooks may pass directly from the delivery end of the raceway tothe anvil uponwhich they are subsequently set. After ahookhas been delivered to said carrier in its inclined receiving position said carrier is moved to a substantially horizontal setting position. V

An important feature of the invention consists in the provision of a rotatable anvil within said carrier arranged to receive a hook edgewise from the racewayand turn it about its axis into the position required or setting. `One manner of effecting this Viesult consists in arranging the anvil so that it may be rotated bodily within the carrier during themovement of the carrier from receiving to setting position by a follower coperating with a spiral guiding member.

Another feature of the invention consists in arranging a hook holding clamp within said carrier in such a way that it shall be moved to engage a hook delivered to the anvil in order to position andV retain the saine during the setting operation. As here- 1n shown, the clamp is maintained in an inoperative position while the carrier is in its receiving position adjacent to the raceway and as the anvil is rotated during its movement to setting position the clamp is gradually pressed into yielding engagement with the back of the hook by engaging with a spiral surface formed in the wall of the carrier.

In order to insure precise operation of the machine in transferring hooks from the raceway to the carrier and also to adapt the machine for handling hooks of irregular shape or non-uniform size, the present invention also contemplates positively acting transferring mechanism of a novel design. To this end a guideway is mounted adjacent to the end of the raceway and arranged for movement toward and from the latter in order to carry a hook-engaging member which is mounted for reciprocation therein, into or out of the path of the hooks on the raceway. A separating fork cooperates with the hook engaging and transferring member, being arranged to act upon the lowermost hook in the line on the raceway separating it from the other hooks and moving it into the path of the transferring member which is then actuated to push the hook to its seat in the anvil.

Still another feature of the invention relates to the manner of feeding the work between successive 'setting operations. In order to expedite the action of the machine and remove the clenched hook promptly Afrom the carrier, so that the latter may be at ficient to draw the hook out from the carrier immediately after the setting operation and before the main or principal feeding operation occurs. In the construction illustrated, a combined upsetting die and punch is employed and the clenched hook is freed from the carrier by a transverse movement of this device while in engagement with the clenched hook. 0n the completion of this movement the punching operation takes place and the principal feeding movement of the work is effected by moving the punch transversely prior to the setting operation.

Another feature of the invention relates to the presser foot and mechanism for operating this elementl of the machine. Heretofore it'has been customary to employ a separate cam for intermittently raising the presser foot during the feeding` operation. The desired results, however, are attained more simply, as herein shown by providing connecting mechanism between the presser foot and the punch or set-carrying member,

Awhereby the presser foot may be raised when the latter is moved into proximity to the work for punching, and held in inoperative position during the feeding operation. These and other features of the invention will be best understood and appreciated from the following'description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings in which 1 Figure 1 is va view in side elevation of a hooksetting machine embodying the present invention; Fig. 2 is a view in front elevation; Fig. 3 is a view, 'partly in section, of

the naceway separator, hook carrier, and upsetting die on an enlarged scale; Figs. L1 and 5 are detail views of the raceway separator;

' Figs. 6 and 7 are plan views of the hook carrier in two different positions; Fig. 8 is an enlarged view, partly in section, of the hook carrier in a position corresponding to that shown in Fig. 7; Fig. 9 is a view in perspective of part of the hook carrier in a position vcorrespondng to that shown Iin Fig. 7; Fig. 10 is a view in perspective of the presser foot actuating lever; Figs. 11 to 13 illustrate different steps in the cycle-of the machine.

The frame 2 of the machine may be of any suitable shape to sustain the moving parts. As shown herein, it comprises a base plate, two uprights or standards and a connecting portion 3 extending between the upper ends of the standards. The standards are provided with journals for the main shaft 4; which is provided at its rear end with a grooved driving pulley 6. The pulley 6 may be clutched to or unclutched from the .shaft 4c by any Vsuitable mechanism. The

mechanism shown herein corresponds substantially to the clutch mechanism described at. length in United States Patent No.

931,066, granted on an application of George Goddu, to which reference may be'had for details of construction. The present clutch, as in vsaid patent, is unclutclied by a cam 8 on the main shaft which acts through a cam lever 9 and toggle links `10 at the proper point in the cycle of the machine and is actuated by springs, not shown, to clutch the driving pulley to the shaft when the toggle is broken by depressing the treadle rod 11.

The hook carrier is mounted on an angle lever 12 pivoted at 1st to a lug projecting upwardly from the upper portion 3 of the frame. The lever 12 is arranged to swing on the side of the portion 3 and at its forward end extends inwardly toward the center of the machine where it is provided with va cylindrical casing 16. Within the Vcasing 16 is rotatably mounted a cylindrical anvil 18 having a hook receiving recess 19 formed in its upper surface. The anvil 18 is provided at its lower end with a spindle20 carrying the arm 21, see Figs. 8 and 8. A spiral spring 22 extends between the spindle 2O and the casing 16 and serves to turn the anvil 18 in a clockwise direction. The position of the anvil is determined by a spiral controlling member 24 rigidly secured to the frame ofthe machine,the spring 22 serving to 'maintain the arm 21 in. contact withfsaid i tion, the arm 21 projects forwardly, in which position the hook receiving aperture 19 is maintained in alinement with the end of the raceway.

As the lever :12 is swung upwardly into hook setting position the arm f 21 slides upwardly on the edge of thecontrolling member 24 4and gradually turns the anvil 18 from the position shown in Fig. 7

through approximately 90 into the position shown in Fig. 6. Y

The casing 16 is provided with twolpassages one of which is in alinement with the end of the iaceway and the recess 19 in the anvil 18 when the latter is in hook receiving position and the other of which extends flaterally Ain alinement withl Vthe aperture 19 when the anvil 18 has been turned into hook f setting relation. The hook therefore is delivered` to the anvil 18 through the rst'mentioned passage and may be drawn out of the anvil 18, as will hereinafter appear, through the second of said passages. A yielding clamping member 26, shown in Fig. 3, is

iic

pivotally mounted within the cylindrical anvil 18 and is normally pressed away from a hookin the cylinder by a leaf spring 27. The clamping member is provided on its rear side with a projecting lug 28 which, in the hook receivingposition of the cylinder, projects into the wide end of a spiral recess 29 formed in theinner face of the casing 16, thus Vpermitting the spring 27 to hold the clamping member out l86 projecting from the of the path of a hook as the latter is being delivered to the cylinder 18. l/Vhen the anvil 18 ,is rotated during the upward movement of the carrier the clamping member 26 is gradually forced toward the hook as the lug 28 moves along the spiral wall of the recess 29 and when the anvil has been rotated into hook setting position the clamp is pressed yieldingly into the depression in the rear side of the hook whereby the hook is prevented from moving during the setting operation. The engagement of the clamping member 26 with the hook, however, is not so firm as to prevent its being displaced when the hook is moved laterally after the setting operati on.

The lever 12 is actuated for setting the hoek by means of a cam 32 on the main shaft 4 which acts on a cam roller carried by a sliding bar 34 guided for reciprocation by bearing pieces 35 attached to the side of the portion 8 of the frame. The slide bar 84 at its forward end is provided with a head having a vertical slot in which is received a pin arm of the lever 12. The hook supplying hopper and raceway 42 are mounted upon a bracket 44 which is supported at its rearend by a link 46 pivoted to the portion 3 of the frame and at its forward end is pivoted to a cam lever 48. The cam lever 48 is pivoted to the frame at 49 and is oscillated by a cam -50 onthe main Vshaft 4. The cam 50 is timed so as to move the delivery end of the raceway forwardly into the position shown in Fig. 1 in which position a hook is transferred lfrom the raceway to the anvil 18 and then rearwardly into the position shown in Fig. 3 'while the upward movement of the lever 12 is taking place. The hopper 40V may be of any suitable or well known type and preferably comprises a casing in which is mounted an apertured rotary separating blade 52 adapted to be rotated intermittently'by a rachet wheel 54 and actua-ting pawl 56 mounted on the link 46. The pawl 56 is held in engagement with the ratchet wheel 54 by a spring 57. It will be seen that as the raceway and hopper are moved rearwardly the pawl 56 will move upwardly engagingV one tooth of the "ratchet wheel 54 while, lon forward movement of the hopper, the pawl 56 will be pulled downwardly thus rotating the separating plate 52. The raceway `42 for the hooks extends without a curve from the hopper 40 to its delivering end, being twisted, however, through 90O so that the hooks delivered with their barrels in a horizontal position by the separating plate 52 will be turned so that their barrels are in a vertical position.

Hooks delivered to the raceway slide by gravity until they are engaged by the separating fork 60 pivoted to a. lug on the raceway, as shown in Fig. 4. The end .of the ing lug Apart of the forward movement of the racefork 60 is bent downwardly and is engaged by a pin 62 mounted in the arm 64 rigidly mounted on the portion 3 of the frame. It will be seen that as the raceway is moved forwardly the end of the fork 60 is held against forward movement so that its operative end will be swung forwardly relatively to the raceway into the dotted line position shown in Fig. 4 thus separating a single hook from those on the raceway. A transferring member 66, having a portion 67 shaped to engage the head of a hook, is mounted for reciprocation in a movable guideway 68 mounted in a slot in the portion 3 of the frame, being held against longitudinal movement by a pin 69 but being slotted to permit a limited transverse or vertical movement. The engaging portion 67 is below the path traversed by the head of a hook during the iii-st part of theY movement of the transferring fork 60 but means are provided for elevating the member 66 during the action of the separating fork so thatthe hook separated from those on the raceway may be engaged by the transferring member and pushed from the raceway to the cylinder 18 when the raceway and cylinder are in proper relative position. To this end a wedge 70, which coperates with a stae tionary wedge 71, is dovetailed into the under surface of the guideway 68. The wedge 70 is provided with a rearwardly eX- tending ear 7 2 which is slotted to receive a pin proiecting from a downwardly extend- 73 on the raceway. During the first way the pin traverses the slot in the ear 72 without affecting the wedge 70 but before the raceway reaches its delivering position the pin reaches the forward end of the slot and thereupon shifts the wedge 70 forwardly elevating the slide 68 sufficiently to move the transferring member 66 into position to engage the hook which has been passed forwardly by the separating fork 60 and is held near the end of the raceway by the spring detent 75. The transferring member 66 is then moved forwardly by the cam lever 76 pivoted to the portion 3 of the frame and actuated by the cam 77 on the main shaft 4. As the raceway is moved rearwardly the spring 78 connected with the rear edge of the wedge 70 acts to retract this member whereupon the guideway 68 is depressed with respect to the raceway into a position in which the transferring member 66 will not interfere with the action of the separating fork 60. In Fig. 8 the movement of the raceway is indicated as being substantially in aV straight line as its departure from a straight path at its delivery end vis so slight as to be hardly noticeable in the relatively short movement which it has.

The upper set 80, which is provided with a central punching member, is mounted in the forward end of a lever 82 pivotally mounted in a swinging head 84. The lever 82 is actuated in a vertical plane by the cam 86 acting through a vertical rod 87 carrying at its upper end a yoke 88 into which therear end of the lever projects. The lever 82 is swung about the vertical axis of the head 84 to effect the feeding of the work, aswill hereinafter appear, by means of a cam 90 acting through a vertical rock shaft 92 which is connected through suitable mechanism with the carrying member 94 'formed integral with or otherwise rigidly secured to the head 84. The extent of the lateral movement of the lever 82 may be adjusted by the connecting mechanism interposed between the vertical rock shaft 92 and the carrying member 94. This connecting mechanism is not illustrated herein .in detail as it forms no part of the present invention but it is disclosed in United States Patent No. 603,023 to Field to which reference may be had for further particulars. The cam 90 for effecting transverse swinging of the lever' 82 differs from the corresponding cam of said patent in that it is arranged to impart to the lever 82 a slight movement toward the left after the setting operation has taken place, this movement serving to feed the clenched hook out df the hook carrier. This feature is of importance in that it permits the carrier to be lowered immediately after the setting operation, thus affording ample time for supplying the next hook to the carrier.

The machine is provided with a work table 100 which isapertured to receive the hook carrier and is provided at one side with a hardened cutting block 102 upon which the punching operation is effected. A presser foot 104 is mounted on the upper end of the rod 106, shown in Fig. 2, and is normally held in engagement with the work by a spring 108 bearing against the under side of the work table at its upper end and against the collar 109 at its lower end. A lifting lever 110 (see. Fig. 10) is pivotally mounted on a bracket 112 at the rear of the work tableA and is arranged to engage under a lug projecting rearwardly from the presser foot. At its rear end theV lifting lever 110 is provided with a curved cross piece 114 having a radius equal to its distance from the axis of the swinging head 84. At a point above the cross piece 114 the lever 82 is provided with a lug in which is mounted a small roller 115 which is adapted to engage the cross piece 114 and lift the presser foot whenever the lever 82 is depressed. When the lever 82 vis depressed for punching the work in its extreme right hand position it will engage the cross piece 114 at some such point as that shown in Fig. 10 and during the transverse movement of the lever 84 the roller 115 will run upon the crossfpiece 114 holding the latter depressed and 4the fpresser Vfoot elevated while the feeding movementof the work is taking place. Means under the control of the operator are also provided for elevating the presser foot when work is to be presented to the machine. As shown in Fig. 2 the lower end of the rod 106 rests upon .a transverse lever 118 pivoted to the-front standard of the frame. An arm having a forwardly extending projection is pivoted on the same axis and is connected with an auxiliary treadle rod 121. By depressing the rod121 the left end of the lever 118 'iselevated andthepresser foot raised from the work table.

The o-peration of the machine will be apparent from Figs. 2 and 11 to 13. In initial position the lever 82 is in its extreme right hand position. with the punch elevated. The presser foot 104 is elevated by the operator and the work presented to the machine and properly positioned with reference to gages, not shown. YThe treadle rod 11 is then depressed and the clutch allowed to engage the driving pulley 'with the main shaft. On rotation of the shaft the punch 80 is virst depressed to the cutting block 102 to punch the work. It is then slightly retracted to relieve the pressure of the cutting block but not enough to disengage the work. During this time a hook has been delivered to the hook carrier which is in its hook receiving position, as shown in Figs.'V 2 and 11. 'Thel punch 80 is then moved toward the left feeding the punched hole into'setting position as indicated in Fig. 11. Thereupon the cam 32 acts to swing the hook carrier upwardly forcing the Vbarrel of the hook into the hole in thework and clenching it against the annular shoulder of the punch, the raceway, being retractedduring this operation. During the setting operation, the punch, which now acts'as an upsetting die, is'again advanced very slightly approximately the distance which it was retracted atthe beginning of the feeding operation. At the conclusion of the setting operation the punch is again retracted but not enough to disengage the clenched hook and 1t 1s then fed 13 whereby the clenched hook is drawn out 11.5 still further to the left as indicated by Fig.

of the hook carrier. Finally the punch is retracted from the work and moved toward the right to its initial position in readiness for a new cycle of operation.
