v Specification of Letters Patent. v E t td 0131;; 226" Application filed IanuaryZ, 15317. No. l4i0,0 7.:

in connection with the accompanying draw-' ings, is a specification; like reference characters on the drawings indicating like parts in the several figures. p This nvention relates to mach nes for setting laclng hooks, studs or slmllar devices and has for its generalobjects to improve the construction, speed and accuracy of operation of such machines.

In operating at high speed it is desirable to engage the work firmly overa considerablearea by the feeding means for in this way the position of the work is accurately controlled and all danger is avoided of distorting the work by pulling it out of shape or otherwise. To this end an important feature of my invention consists in clamp feeding mechanism of novel construction. As herein shown a movable clamping member is provided which takes the place of the'usual stationary work table, this member with its cooperating clamping memher being swung transversely about a common. axis in feeding the work.

Another feature of the invention consists in an improved hook carrying device for receiving the hook from a raceway and inserting it in the work. As herein shown;

this device includes an anvil plate, the po sition of which is positively 'but adjustably determined so that the hook may be pre sented accurately in line with the upsetting die. In this connection another feature of the invention consists in automziticmechanism for moving the anvil plate to and from operative positionconstructed and arranged to control the transverse POSllIlOII of the.

anvil plate throughout its vertical movements to and from setting position.

Still another feature of the invention consists in novel mechanism for separating the hooks in the raceway and'transferring them v to the anvil plate. From a mechanical standpoint it has been found advantageous so to connect these devices that one operates the other and such construction is herein show'nl These and a features er a6 jinv'eiaitn will be best understoed and appreciated from the following descrlption' of apreferred embodiment thereof selectedhfor purposes of illustrationand shown inthe accomp'anying drawings, in which, I

timed relation.

The

lower portion of the frame vided with vertieal bearings for a reciprocatory plunger 90 upon the upper end of which is mounted a hook supporting mem ber 92. The plunger 90 has secured to it a collar 94 carrying a pivoted block by which connection is made to the forward end of a cam lever 96 journaled about a transverse shaft 98 in the machine frame and havlng forks 100 formed at its rear end which embrace the operating cam 102 on the shaft 22. The cam 102 is so set as to move the hook carrier vertically simultaneously with and in an opposite direction to the movement of the upsetting die 6. v

The plunger 90 has undercut ways at its upper end, as shown in Figs. 1 and 7 which engage with an annular flange formed in a threaded nut 91. The nut 91 receives the shank of the hook supporting member 92, the vertical position of which may be adjusted by turning the nut 91 to bring the member 92 and the anvil 106 resting in the slots in said member into position opposite the raceway 164. .This interengagement of the anvil and the member 92 will insure the lateral alinement of the anvil plate and support it during the setting operation, .and is maintained throughout the cycle of the machine. In its'upper end the hook plate supporting member 92 is recessed to receive a spring pressed clamping member 93 shaped to engage the crown of the hook and hold the hook in place during the setting operation.

A screw 95 en a in a slot in the V .i 6 member 93, lim ts its vertlcal movement.

'An' anvil plate 106, shaped to enter the throat of the hook, is supported upon the upper end of a lever108 by an outwardly and downwardly extending shank. This shank is received in a cut away portion of the hook supporting member 92. By means of this arrangement, the size of the part of the anvil which must pass through the work supporting table is reduced and provision made for the relative displacement of the anvil and the member 92 after the hook has been set and while the parts are still within the opening in the table 46 (see Fig. 10).

The upper end of the member 92 is provided with guiding and supporting grooves adapted to receive and support the lateral edges of the anvil plate adjacent to its active end, thus insuring the exact lateral .alinement of said plate with the die 6 and tion is effected through a link 114, see Fig. 12, which is pivotally connected to the lever 108 by a pin 113 disposed a short distance below the upper end of the lever. The link 114 has a pair of transversely extending lugs forming bearings for a rod 116 having a collar engaging one end of a compression spring 118 the other end of which bears against one of the lugs upon the link 1114. The rod 116, which in effect forms the yield ingextension of thelink 114, is provided at its rear end with a head 120 which is pivotally connected by a pin 121 to a rocker arm 122 journaled on the transverse shaft 124.

The upper end of the rocker arm 122 is connected through a link 126 to an oscillatory cam lever 128 which will be referred to parted to the link 114 is sufiicient to move the stop 107 inwardly to its limit and then compress the spring 118 so that the lever 108will be held firmly but yieldingly in place during the upward movement of the plunger 90. While this movement takes place the link 114 will swing about the axis of the pin 121 and the spring 118 will be furtherficompressed although this compres- 'sion will have no effect upon the position of the anvil plate as will be apparent.

Lacing hooks are supplied to the hook carrier from a hopper 140 which may be of any desired construction. As herein shown, it is provided with a picker plate 142 driven intermittently through a slotted disk 143 by a pin projecting from a gear 144 journa'led upon a shaft set in the hopper bracket. The gear 144 meshes with a pinion 146 on the end of a shaft 150 whicheXtends-transversely acrossthe rear of the machine and is provided with a driving pulley 152 at its outer end. The pulley 152 is connected through a belt to a small pulley 156 formed on the loose member of the driving clutch. The lacing hooks are delivered to the race- ;way'160 from the hopper 140 and pass along the raceway by gravity until they reach the separator plate 162. This is shown in Fig. 11 from which it will be apparent that successive lacing hooks are delivered sidewise to the lip of the separator and are then transferred tofthe lower section 164 of the raceway down which they pass with the hook opening in advance. The separator 162 is oscillated through a link 166 con nected at its rear end to the upper end of the cam lever 128 'before mentioned. The cam lever 128 is journaledupon the stud 20 and provided at its lower end with forks 132 which receive a block pivotally mounted upon a bracket 134 projecting upwardly from the reciprocatory slide 60. A portion of the periphery of the separator is pro.- vided with gear teeth which mesh with a rack formed upon the horizontal moving transferring member 168. bored longitudinally to receive a spring pressed pin 170 (see Fig. 1) which is arranged to engage the rear side of each hook released by the separator and push it along the raceway section 164 to set it securely upon the anvil plate 106 where the hookis held by the spring clamping member 93.

Thework in which the hooks are to be set is positioned upon the table 46 shown best in Fig. '12, which constitutes also the lower member of a clamp feeding mechanism. The table 46 is supported by a downwardly and rearwardly extending shank 48 having a hub 50 through'which passes a rod 36 constituting the axis about which the table 46 swings in the feeding operation. The table 46 is bifurcated so that it may be moved close to the setting instrumentalities. Oppositely disposed to the rear branch of the table is the upper. clamping member 44 which is substantially coextensive with said rear branch and has also a downwardly and rearwardly extending shank 40 whichacts as an edge gage for the work and is provided with a hub to receive the rod 36. The clamp member 44 is fast to the rod 36 and is moved vertically thereby as will presently appear. A pin 42 fast to the shank 40 of the upper clamping member and projecting into a bore in the shank 48 of the table insures the equal and simultaneous movement of the two clamping members. The shank 48 of the table has an upwardly extending arm 52 terminating in a split clamp 54 which holds a pin 56. To this pin is connected thefforward end of a link 58 which forms a part of the feeding mechanism. The other end of the link is connected to the split end 68 of a link 67 pivotally mounted upon the slide bar 60. The bar. 60 has downwardly projecting jaws 62 which embrace a cam 64 on the shaft 22 timed to move the bar 60 forwardly and so-swing the clamping members toward the left, as seen in Fig. 12, when it is desired to feed the work. The links 58 and 67 are connected at their common point by a pin -69 and guided in their movement by double radius rods 72 which extend from a sleeve 74 rigidly connected to the spacing lever 76. The spacing lever is pivotally mounted upon a stud 7 0 set in an arm 80 projecting from the machine frame and is urged by a spring 75 rearwardly or toward a position corresponding to a minimum feeding movement. This handle may be held in adjusted position by a pin 81 inserted in the plate 82 (see Fig. 2). As the spacing lever is swung toward the left, as seen in Fig. 12, the axis ofthe radius rods72 is movedto such position The latter is that more and more of-the motion of the slide bar 60 i transmitted to the work clampingmem'bers 44 and 46. The arrangement'of the feeding mechanism is. shown diagrammatically in my prior patent above identified to which reference. may be had for further details of this mechanism.

Vertical movement of the upper clamping member 44 is effected through the rod 36 by mechanism which will now be described. The rod 36 is held against angular movement and provided at its lower end with a' head carrying a roller 34. A compression spring 38 bears upon the upper side of the head and against a portion of the machine frame, as shown in Fig. 12, tending to move the clamping member 44- downwardly and into engagement with the work. The roller 34 is arranged to runupon the upper surface of-a cam 32 fast upon a horizontal shaft 30 arranged to slide forwardly and rearwardly. The rod 30 is connected through a link 28 to the lower end of an extension 26 formed upon one branch of the cam lever 18. vlNhen this lever is moved forwardly at its upper end to depress the upsetting die, the'roller 34 is lifted by the cam and the clamping member 44 disengaged from the work. On the other hand when the lever 18.is moved to elevate the upsetting die at the conclusion of the setting operation the low portion of the .cam 32 is moved beneath the roller 34 and the spring 38 permitted to lower the member 44 to engage the work.

In order to permit the clamping member 44 to be elevated for the insertion of the. work, its shank 40 is provided with a rearwardly extending projection 180 arranged vto be engaged by a cam 182 fast to a transverse shaft 183. At its outer end the shaft 183 carries a forwardly extending arm 184 to which is connectedatreadle rod 185. Depression of the treadle rod turns the shaft 183 and so lifts the clamping member 44 temporarily against the compression of the spring 38. This movement, it will be understood, takes place independently of the intermittent lifting of the clamping member caused by the reciprocationof the cam 32..

The driving pulley 3 runs loose upon the main shaft and suitable starting and stopping mechanism is provided for clutching and unclutching the pulley to the shaft as desired by the operator. Timing mechanism is also provided by which the machine may be stopped aftera predetermined number of complete cycles. This mechanism is not herein described as it forms no part of the be briefly outlined. The spacing lever 76 crating slots in the member 92. Figs.

is moved preliminarily in accordance with thespace desired between the hooks and is held in place'by a pin 81 set in the spacing plate 82 (see Fig. 2). The upper clamping member 4 1- is then elevated to permit the insertion of the work, the shank of this member acting as an edge gage as will appear'from Figs. 7 and 8. The machine comes to rest with a hook in place upon the anvil plate 106 so that when the machine is started the hook is at once forced upwardly through the 'work and its barrel clenched against the upsetting die 6 which is simultaneously forced downwardly. During the setting operation, the active end of the anvil plate is supported by the coop- 7, 8 and 9 indicate successive stepsin the operation of inserting and clenching a hook. At

the conclusion of the settting operation the upper clamping member A l is elevated and before the hook is disengaged by the setting instrumentalities the two work clamping members are swung toward the right, as seen in Figs. 2 and 12, and then the upper clamping member is lowered into engagement with the work. As soon as the work is engaged by the clamping members the upsetting die 6 is elevated and the hook carrier lowered. Figs. 3 to 6 show success1ve steps lnthe operation oi the cycle ust discussed. During this time the anvll plate 106 is swun outwardl to disen a e the clenched book, as shown in Fig. 10, such a movement being allowed by the shape of the shank of the anvil and the relation between said anvil and the member 92. This plate is then lowered with the hook carrier, being returned to its initial position where it is received in slots in the member 92 when the hook carrier reaches its lowermost position in alinement with the raceway'section 16 1. During this time the clamping members are moved toward the left, as seen in Figs. 2 and 12, and the work advances to bring the point at which the next hook is to be set into alinement with and between the setting instrumentalities. The final step in the cycle consists in the oscillation of the separator plate l62 whereby a hook advanced into the path of the transferrer 168 is pushed by the latter upon the anvil plate 106.
