To all lwhom t may concern:

Be it known that I, FREDERICK lV. Lus- GoMB, a citizen of the United States, and resident of New Bedford, inthe county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Hook-Setting Machines, ofr which the following is a specification.

This invention relates to machines for setting lacing hooks, and consists in features relating to the hook-transferring means, and

to the timing of the hook-sustaining member and the setting tool whereby the latter is caused to relieve the pressure on a set hook but to remain in the shank of the set hook to hold the work while the hook-sustaining member is being withdrawn from the hook.

Of the accompanying drawings: Figure 1 represents a front elevation, partly in section, of a hook-setting machine embodying the present invention. Fig. 2 represents a side elevation, partly in section, of the front portion of such machine. Fig. 3 represents a section, in a horizontal plane, of a mechanism which feeds the work. Fig. 4 represents a vertical section, on a larger scale, of the cooperative hook-setting elements in the act of setting a hook. Fig. 5 is a View similar to Fig. 4, showing the setting tool raised slightly above the position shownby Fig. 4 and showing lthe hook-sustaining member as having been withdrawn from the set hook. Fig. 6 represents a side elevation of the operating mechanism which imparts movement to the setting tool. Figsy7 and 8 show the two coperative cams which are included in Fig. 6. Fig. 9 is a front elevation of the crank-disk and crank-pin which transmit motion from the operating mechanism shown by Fig. 6 to the setting tool, and includes broken lines indicating the several angular positions at which the crankpin dwells.

The same reference characters indicate the same parts wherever they occur.

The setting tool in the present instance is provided with a central projection which cooperates with a punch-block to punch a hole in thework. At the time of the punching 'operation the setting tool is at one side of its setting position, and after the punch has been brought to bear on the punch-block it is raised enough to relieve the pressure on the punch-block but not enough to withdraw theA punch from the work. 'While the punch reraised to pass the shank of the hook through the. punched hole in the work and to clench the hook against the setting tool. When the setting operation has been completed the isetting' tool is raised sufficiently to relieve the pressure upon the set hook but not enough to withdraw thepunch from the shank of the hook; and while the setting tool remains in this position to hold the work by means of the set hook, the hooksustaining melnber is withdrawn from the hook.

The setting tool is indicated at 10, and the punch formed thereon is indicated at 11. This tool is carried by a vertically movable plunger 12. and the plunger is arranged t0 slide in a sleeve 13 formed upon a sliding carriage 14. The carriage moves from side to the side on dovetailed guides 15, 15 to feed the work.

The punch-block which coacts with the n punch is indicated at 16. A presser-foot 17y is arranged to coact with the punch-block and is operated by suitable mechanism which causes it to release the work for feeding but to clamp the work at other times. The presser-foot is carried by a plunger 18 and the latter is arranged to slide vertically in guides 19, 19. A collar 2O is affixed to the plunger 18 and is provided with a pin 21 (Fig. 2) which is engaged by aforked lever 22. This lever is in the form of a bell-crank and is mounted upon a fulcrum stud 23. An operating rod or@ link 24e is pivotally connected to the lever 22 and transmits mo- Ation from suitable operating mechanism lectively the hook-sustaining member. The

hook-sustaining member is pivotally mounted upon a vertically movable carrier 27 by means of a pivot pin 28. The carrier 27 iS provided with cam rolls 29 and 30 which coact respectively with cams 31 and 132. These cams are carried by a shaft 33. The cam 31 raises and the cam 32 depresses the carrier 27 When thecarrier is fully depressed the hook-sustaining member stands in register with thedelivery end of a raceway 34. This raceway is one element of the hook-feeding means.

Any suitable mechanism may be employed for feeding lacing hooks one at a time to theraceway 34. Fig. 2 shows a feeder 35 for this purpose, andv this figure includes also a feeder 36 by which the lacing hook m is pushed from the delivery end of the raceway to the plate 25 of the hook-sustaining,

member. -No further description of the p hook-feeding means will be necessary for the purposes of the present invention.

The purpose in mounting the hook-sustaining member upon a pivot as indicated at 28 is toenable it to be tilted to withdraw 4it from the set hook. The withdrawing motion is accomplished by a cam 37 on the shaft 33, and the return motion is accomplished by one or more springs, two companion springs 38 (Fig. 1) being shown in the present instance. Titling motions are transmitted to the hook-sustaining member by a link 39. The upper end of this link is connected to the hook-sustaining member by a pivot pin 40. As shown by F 1g: 1 the link is provided with an elongated slot 41 and the shaft 33 extends through this slot so as to engage'the straight vertical surfaces thereof to, guide the link.' The link carries a. cam-roll 42 which coactswith the under side of the' cam 37. The springs 38 are attached to the link 39 in such manner as to maintain an upward stress -on the link, thus keeping the roll 42 in contact with thecam 37 and causing the hook-sustaining member` to tilt from the angular. position shown by Figs. 2 and 5 to the upright positionshown by Fig. 4 in keeping with the formation of the cam. In order, however, to limit the tilting movement of the hook-sustaining member to hook-receiving position, the hook-sustaining member is provided with a pin 43y (Fig. 2) which projects laterally so as to coact with a stop shoulder 44 on the carrier 27.

The hook-sustaining member describes the following movements: Assmming that a hook has just been set as shown by Fig. 4 and that the setting tool has been raised enough to relieve the pressure upon the set hook, the cam 37 -dbpresses the link 39, thus tilting the hook-sustaining member to the positionv shown by Fig. 5. The plate 25 of the hooksustaining member is thus withdrawn from the set hook. The carrier 27 is then depressed by its cam 32 to carry the hook sustaining member into register with the delivery end of the raceway 34, and while such movement is occurring the cam 37 pervmits the hook-sustaining member to tilt t its upright position under the iniuence. of the springs 38. The feeder 36 is then moved forward to push the hook from the rac'ewayr of placing the hook incorrectlv upon thel plate 25. Assuming, however, that no such difficulty arises, the carrier 27 will in due A course rise with the hook-sustaining member in the angular position shown by Fig. 4 and will thus cause the shank of the laclng hook to pass through the stock a and engage the setting tool. y

The plunger 12 which carries the setting tool has a head 45 at its upper end, and this head is formed with a horizontal grooye A wrist-pin block 47 is arranged to slide 1n the groove and isbored for the reception of the wrist-pin indicated at l48. This pin 1s carried by a disk 49 which is formed upon or aiiixed tothe forward end of a rockshaft 50. Referring now to Fig. 6, the rockshaft 50 carries at its rear end 4adisk 51 on whichis formed or in which is set'a wristpin 52. A connecting rod 53 is fitted to the wristpin 52 andlits lower end is formed with a slot 53 (Fig. 7) through which the cam shaft 33 extends. tical surfaces of the slot engage the shaft and the longitudinal movements of the rod are guided by this means. vThe rod 53 carries cam-rolls .54 and 55 which coact respectively with cams 56 and 57. Cam 56 imparts downward movement to the setting The straight ver tool and cam 57 imparts upward movement.

vReferringto Fig.' 7 the high portion 58 is the portion which causes the punch 11 to.

punch the hole in the stock. Referring to- Fig. 9, line b indicates the angular position of the wrist-pin 48 when the setting tool is at its highest position. The punching motion of the wrist-pin is from line b to line 0. The cam 57 has a depression 58 which is the counterpart of the punching portion 58. As soon as the punching motion has been completed the punch is raised slightly and 60 of these two cams maintain the 4punch in the stock as last described for a sufficient length of time to enable the punch to4 move laterally to Lfeed the stock into hook-receiving position, and to sustain the setting tool in setting position While the hook-sustaining member rises to insert. and cleneh the hook.

When the hook-setting members have reached the relative positions shown by Fig. 4 the shoulder 61 of cam 57 is about to engage the roll 55 to raise the sett-ing tool. to the position shown by Fig. 5. Referring again to Fig. 9, the corresponding movement of Wrist-pin 48 is from line d to line e. The depression 61" (Fig. 7) is the counterpart of shoulder 61. This shoulder 61 raises the setting tool enough to relieve the pressure of the latter upon the set hook but not enough to withdraw the punch from the shank of the hook, and when the setting tool has been thus raised the hook-sustaining member is Withdrawn from the hook as hereinbefore described. After the hooksustaining member, has been Withdrawn from the hook the setting tool is raised by thesportion 62 of cam 57 which, according to Fig. 9, carries wrist-pin 48 from line e to line b, whereupon the sliding carriage 14 is moved to the right from the position shown by Fig. 1 preparatory to repeating the punching motion.

The mechanism for reciprocating the feed carriage 14 is not of special importance so far as this invention is concerned, but vmay 4be described brieiy as `far as it is shown.

Referring to Fig. 3, the feed carriage is provided with a toothed rack 63. This rack is engaged by a spur-gear segment 64. Another spur-gear segment 65, formed upon or afiXed to the segment 64, is engaged by a toothed rack 66. The latter is carried by a bar 67 which is arranged to slide back and forth. The bar 67 transmits motion from suitable cams (not shown), said cams being vtimed to lcause the feed motion and the relink and arranged to act thereon to tilt saidV hoolcsustammg member to hook-sustalnmg position, and a cam arranged to act on said link to retract said hook-sustaining member from hoolesustaining position.

In testimony whereof I have aiiXed my signature.

FREDERICK W. LUscoMB.
