ARTHUR R. HAVENER OF WALTHAIVI, MASSACHUSETTS, ASSIGNOR TO AMERICAN LACING HOOK 00., A CORPORATION OF NEW JERSEY.

MACHINE FOR SETTING LACING-HOOKS IN THE UPPER OF A BOOT OR SHOE.

ocales.

To all whom it may conccm Be it known that I, ARTHUR H. T'IAVENER, a citizen of the United States, residing at Walt-ham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in hilachines for Setting Lacing-Hooks in the Upper of a Boot or Shoe, of which the following is a specification.

This invention relates to an improved mechanism for setting lacing hooks in the uppers of boots and shoes and is an improvement upon the machine of the invention of Arthur R. Havener patented November 29, 1910, No. 977,090.

The object of the invention is to provide a machine of the character set forth in which an organized mechanism for setting lacing hooks in the uppers of boots and shoes is supported upon a frame, the frame itself being hinged to a base so that said frame and its organized mechanism may be tipped at an angle to the base to allow the different parts of the mechanism to be readily accessible, especially the parts attached to and connected with the main driving shaft of the machine, while upon the base is mounted mechanism to operate the clutch mechanism and also to operate, preferably simultaneously, the means whereby the presser foot is moved toward or away from the worksupport.

It is the object of this invention still fur- [her to provide an improved and convenient mechanism for varying the feed of the up per, so that the punch will feed the upper from a certain given point different distances and thus vary the space between the lacing hooks, this improved mechanism being soarranged and constructed that it can be quickly and accurately changed.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a front elevation of my improved lacing hook setting machine partly broken away to save space in the drawings. Fig. 2 is a side elevation of the machine, also partly broken away and viewed from the right of Fig. 1.

Fig. 3 3-3 of Fig. 2. Fig. 1: is a detail sectional elevation taken on line l-1 of Fig. 25. Fig. 5 sectional elevation taken on line of Fig. 1, as viewed from the left of said figure. Fig. (5 is a sectional elevation of the clutch taken on line (3-43 of Fig.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, is the frame of the machine and 11. the base. Said frame is pivoted or hinged to the base '11 at 12 and is fastened to said base in order that it may not tip upon said pivots by screws 13, 1 1 which extend through cars 15, and 16, re- SIMBCllVOly, on the frame 10 and have screwthrtauled engagement with cars 17 and 18, respectively, on the base 11. Thus the frame is fastened firmly to the base.

The main. driving shaft 19 is journaled in biarings Q0 and 21 on the under side of the frame 10 and is rotated by a clutch pulley 22 journaled to rotate upon the main driving shaft 19 and adapted to be locked to said shaft by the clutch member 28. The clutch pulley forms one member of the clutch mechanism and the part 23 forms the other member. The part 2:, is keyed to the shaft 19.

A locking dog or arm 24L. is pivoted to the member 28 and when in the position illus trated in Fig. 6, that is, with the tripper slide 25 in engagement therewith, said looking dog allows the clutch pulley 22 to 1'0- tate freely without rotating the shaft. \Vhen, however, the tripper slide is withdrawn from engagement with the locking dog 24, said. locking dog is immediately thrown outwardly at its free end by the spring 26 and is then engaged at the shoulder 2? thereon by one of the clutch teeth 28. The two members of the clutch 22 and 23 are then locked together and the rotation of the pulley in the direction of the arrow thereon causes the member 28 to be retated in the direction of said arrow together with the shaft 19 to which it is fastened.

Vv'hen the machine is at rest and the operator is placing an upper in position to have a lacing hook set therein, the pulley .22 is free to rotate on the shaft 19 and the trip is a sectional elevation taken on line per slide is in engagement with the locking dog 24. The tripper slide 25 is moved to engage the locking dog 2% by a spring 29 and is moved in the opposite direction to disengage the same fro-m said locking dog by a treadle (not shown in the drawings but connected by a treadle rod 30 to a lever 31). The lever 31 is fast to a rockshaft 32 (Figs. 2 and 8) which is j ournaled to rock in bearings in the base ll. An arm 33 is fastened to the rock-shaft 32 and engages a pin 34k in the tripper slide 25, whereby said slide is moved in the opposite direction to that in which it is moved by the spring 29.

The lever 31 is connected by a link 35 to a lever 36 pivoted at 37 to the base 11, the end of the horizontal arm of said lever pro jecting beneath the lower end of a treadle rod 38. The treadle rod 38 is adapted to slide in bearings 39 and 40 in the frame 10 and has fastened to its upper end a presser foot tl. The treadle rod 38 is encircled by a spring 42, the upper end of said spring adapted to bear against the lower face of the bearing 40, the lower end of said spring bearing against an arm 43 which is guided by a plate 4% fast to the frame 10.

The presser foot 4:1 normally rests upon the work-support 45 and may be raised or lowered by means of the treadle rod 30 acting through the lever 31, link 35 and lever 36, and during the automatic feeding and setting operation said presser foot is raised and lowered by means of a lever 46, one end of which projects through a slot 4:7 in said treadle rod. The lever 46 is pivoted at 48 to the frame of the machine and is operated by a cam 49. I

The mechanism for separating and feeding the lacing hooks and set-ting the same in the upper of the shoe forms no part of this invention but is fully shown and described in said Letters Patent. The upper is fed by a punch 50 which is fastened to a slide 51. This slide 51 is adapted to slide upon two horizontal rods 52. The rods 52 are fastened to a plunger 53 which is adapted to slide vertically in bearings 54: on the frame 10. A vertical motion is imparted to the plunger 53 by a rock-shaft 5 L, said rockshaft having fastened to its forward end an arm with a pin 56 fast thereto and projecting into a sliding block 57. The sliding block is located in a segmental slot 58 provided in a block 59 fast to the plunger 53.

A. rocking motion is imparted to the shaft 54- by an arm 60 which is connected by a link 61 to a lever 62 pivoted at 63 to the frame 10, said lever having a rocking motion imparted thereto by a cam 6st.

A horizontal motion is imparted to the punch 50 by a rock-shaft 65 to which an arm 66 is fastened, said arm having a pin 67 fast thereto and projecting into a sliding block 68. The sliding block 68 is free to move vertically in a slot 69 formed in the slide 51. A rocking motion is imparted to the rock-shaft 65 by an arm 70 fast thereto and connected by a link 71 to a lever 72 pivoted on the rod 63 and having a rocking motion imparted thereto by the cam 73. Thus a vertical movement is imparted to the punch to move the same toward and away from the upper 94 and a horizontal movement is imparted to said punch in order that the same may feed the upper step by step.

and thus space the hooks the proper dis tance apart in said upper.

It is desirable in a machine of this class that the mechanism should be arranged so that the feed of the upper referred to can be varied so that lacing hooks may be spaced at different distances apart and it is also very desirable that this change in the length of feed of the upper shall be capable of being performed with ease and accuracy. Moreover, such a change in feed must be so arranged that the punch will always feed from the same point to a greater or less dis tance therefrom. To accomplish these results the link 71 is pivotally attached to the lever 72 at 74 and is adjustably fastened to the arm 70 in a manner now to be described. Said link is bifurcated at its upper end, thus terminating in two arms 75 and 7 6. A sleeve or bushing 77 is rigidly fastened to the arms 75 and 7 6 and has rotatably mounted thereon a sliding block 78. A locking pin 79 is mounted to slide longitudinally thereof within the sliding block 78 and has formed upon its front end a tooth 80, the crown 81 of which is in alinement with the median axial line a of the locking pin 79 (see Fig. 4L). The rear end of the locking pin 79 is slotted at 82 to receive the end of a locking lever 83 which is pivoted at 84c to the link 71. A spring 85 holds the locking pin 79 normally in the position shown in Fig. 4;.

The arm 70 is provided with a segmental slot 86 in which is located the sliding block 78. The tooth 80 on the locking pin 79 projects beyond the front face of the arm 75 and engages teeth 87 on a segmental plate 88, which plate is fastened by screws 89 to the arm 7 O. The opposite ends of the segmental plate 88 preferably rest upon forwardly eX- tending portions 90 of the arm 7 0, thus leaving a slot 91 between the plate 88 and the front side of the arm 70 and within this slot the outer end of the arm 7 5 projects.

The segmental slot 86 is concentric with the median axial line of the pivotal pin 7% when the slide 51 is located at the extreme right of its throw as viewed from the front of the machine in Fig. 1. The slide is then in the position for the punch to begin its feed, that is the point to which it is necessary to bring the punch at the beginning of each feed, although the punch may be moved to a greater or less extent from that starting point according to the position in which the locking pin 79 is placed relatively to the center of the rock-shaft (55. Both the crowns and the bottoms of the teeth 87 are also preferably formed concentric with the median axial line of the pin 7st when the parts are in the position wherein the punch is just beginning to feed and. it will be understood that the crown 81 oi the tooth 80, when the same engages any one of the teeth 87, is in alinement with the median axial line a of said locking pin 79.

A b 'acket 92 is fastened to the frame 10 oi. the machine and said bracket has a horizontally extending arm 93 thereon which projects from the fame 10 transversely of the link 71 and adjacent to the locking pin lever 83 said arm is inclined transversely thereof to a vertical plane and forms a rest for the hand of the operator, so that when it is desired to change the feed he can rest his hand upon this bracket arm 93 and press the looking pin lever 83 to move the pin 79 out of engagement with the teeth 87 and move the pin along to any desired portion of the slot 86 while his hand rests firmly upon said bracket. lV hen it is desired, therefore, to change the throw or extent of movement imparted by the lever 72 to tl i arm and thus, through the connecting parts, to change the feed of the punch laterally thereof, the operator moves the locking pin lever 83 by pressing the same toward the link 71, thus moving the locking pin 79 out of en gagement with the teeth 87 upon the plate 88 or, in effect, upon the arm 70 as said plate 86 is rigidly fastened to said arm. The operator then moves the link 71 to any desired position and releases the locking pin lever 83 so that the locking pin 79 may engage any desired one ot the teeth 87, these teeth being conveniently indexed upon the front side of the segmental plate 88 by means of suitable letters or figures and by index lines running from the bottoms of the teeth along the front face of said plate, as shown in Fig. 3. Thus, it will be seen that as the link 71 is moved toward the right from the position shown in Fig. 3 to engage the teeth at the right hand end of the segmental plate 88 the throw of the arm 70 will be decreased, while if said link is moved toward the left from the position shown in Fig. 3 to engage teeth nearer the rockshal't 65, the throw of the arm 70 will be increased. Moreover, it will be understood that as this change in position of the link 71 is made while the punch is at the extreme right of its movement or in the position when it begins to feed the upper there will be no change in location of the arm 70 caused by this relative change in location of the link 71. thereto, on account of the segmental slot 86 being curved concentrically with the median. axial line of the pin 74.

when the parts are in the relative positions hereinbefore set forth, so that the entire throw imparted to the part or parts connected to the arm 70 will be imparted by said arm from the position in which the punch is at the extreme right or beginning of its throw to the position which it assumes at the other end of its throw and said part or parts connected to said arm will always be brought back to the same position at the beginning oi? the throw, irrespective ot' the extent of said throw or feeding movement.

It will be understood that the operation of the machine of this invention, in order to be practical, must be very rapid and that to change the throw of the punch, hereinbetore described, with ease and accuracy, without something to rest the hand upon, is very dillicult ii? not impossible, as the operator would be liable to move the link several teeth too liar in one direction or the other, but by supplying the bracket 92, with its horizontally extent ling arm upon which to rest the hand of the operator while making this change, the operator is enabled to perform the adjustment of the link Tl relatively to the arm 70 with ease and a .-curacy.

The general operation of the mechanism hereinbeiore specifically described is as follows: The operator places the upper 94 to have the lacing hooks set therein upon the wtn-k-support l7. At this time the presser foot is in its raised position. The operator then depresses the treadle, pulling downwardly upon the trcadle rod 30 and rocking the lever 3t so as to move the tripper slide out of contact with the locking dog 24, thus throwing the clutch into operation, as hereinbefore described, and rotating the shaft .19. At the same time that this operation takes place the lever 30 is rocked, through the link 35, so as to lower the end of the lever which is in contact with the lower end of the rod 38, thus allowing the presser rod 38 and the presser :toot il to descend and clamp the upper U-lto the worle support. The punch 50 then descends, punches a hole in the upper and feeds the same step by step the proper distance, ac cording to the position oil the locking pin 79 in the slot so. At each feeding movement the prcsser foot 41 is raised and lowered automatically by the lever to.

It will be seen that the movement where by the presser foot is lowered into contact with the upper and the trippcr slide 25 is operalet l to throw the clutch into operation are simultaneously pertornied by the single rod 530 and its treadle and that all of the working parts constituting the lacing hook setting mechanism are su iported upon the lrame 10. while the levers For operating the clutch slide and presser foot are mounted upon the base.

hen it is desired to tip the organized lacing hook setting mechanism with the frame 10 upon which it is mounted at an angle to the base 11 to allow the different parts of the mechanism to be'readily accessible, the screws 13 and let are removed and the frame 10 with its organized lacing hook setting mechanism will then be free to be tipped upon the pivot 12.
