This invention relates to a machine for setting fastening devices, such as lacing hooks, along the edges of the uppers oiboots, shoes, and other articles.

.The'invention has for one of its objects to rovide' in a machine which punches the 'oles. for the fastening devices and then affixes the fastening devices in such holes, means for varying the spacing between the punching devices and settingdevices of each '.gan or series so that such machine may be emp oyed in operating upon uppers of vary' ing sizes and styles. I

'0 her objects and advantages ofthe invention will be pointed out in, the appended description.

In the present instance, we have shown the various features of our invention embodied in a hook setting machine. be obvious, however, that certain of the features mav be used independently of each other and for setting other fasteners than shoe hooks.

Referring to Fig; l, 20 indicates the base -of the machine which has a standard 21. The standard 21 is provided with a raceway 22, the sup 'orting frame 23 of which is adapted to s ide' back and forth in the usual manner of; such devices. The means for reciprocating the raceway consists of a lever 24 which is ivoted between its ends to the standard and at its upper end, as at 25, is. in pivotal enga ement with the. raceway frame, the other cm of the lever cooperating with a suitable cam 26 shown in dotted lines in Fig. 1 and fixed on a suitable drive shaft 27 journai ed on the frame of the machine. A contrac'tile spring 28 is anchored -at'one'endto the lever 24 and at its other end to a fixed part of the standard. The-s ring 28 is designed tomove the raceway ame forward, w ile the cam 26 cooperates with the lever to retract the raceway in opposition'to the 29 which is inclined at a suit: le angle,' and a cut instance of-suitable strips standing on The forward en of each hinged section 31 is lowerportions of the leaves forming the bi- "Fig. 10. Adjacent the end of each'guide is ,8; pivoted finger 34-which serves as a stop to arrest the .hooks and hold them until rehook guides and the tongue of the hook" It will spring. The racewayis coin osed of a plate plurality of. guides which consist in the pres' edge onthe u er face ofthe )late and of a El l u moved train the guide, in the manner herein so as to'.be .ca able of swinging laterally.

split vertically or bifurcated, at 33, and the furcation are flared outwardly, as shown in after explained. The hooks a are fed to the guides from a suitable reservoir (not shown) and the number of guides corresponds'tothe number of hooks to be set at each operation.

The standard 21 is provided with aforwardly extending arm 35 having a depending head 36to which is fixed and from which projects downwardly an abutment 37". This abutment has at its ends rearwardly extending brackets 38, supporting a transverse guide which in the present instance-consists of a pair of rods 39 the ends of which are fixed to the brackets. A plurality of carriers, the number ofwhichcorresponds to the number of hooks to be set at each operation and Which by their lateral adjustment vary the spacing of the punches and sets, are slid ably mounted on the guide rods 39. Each of these carriers consists in the present instance ofa plate 40 having suitable apertures through which the guide ,rods 39 pass, a forwardly extending plate 41 secured to the plate 40 and carrying the stationary set 42, a depending guide strip 43 on which the associated punch 44 and anvil 45 are mounted,

" as hereinafter described, and a forwardly extending arm 46 slidably mounted on the guide and carryingthe movable set 47.

As shown in Figs. 2 and. S'the forward end of the plate 41 extends under the abutment 37 and abuts thercagainst, and the set 42 secured to the under face of the same may be of the usual or any suitable character. The guide strips 43 which are fixed to and depend from the plates ,4], are provided on corresponding faces with horizontal guide ways which extend longitudinally of the machine and, in. the present instance consist of channel plates 48. [n each channel plate is a slide 49 standing on edge, the rear ends of the severalslides "b'eingconnected by across rod 50, on which they are slidably mounted for lateral adjustment. The rod 50 has pivoted to its end links 51 the rear ends of which are slotted, as at 52, each to receive a stud 53 on the plate'ZQ of the raceway. By reason of this connection the slides 49 are reciprocated simultaneously by the raceway and lost motion between the raceway and slides is produced at the beginning of the movement of the raceway in either direction. Associated with each slide 49 is a punch block 54 having fixed thereto on itsupper face the punch 44 which may be of any suitable form, the aperture therein communicating with a suitable outlet passage 55, in the punch block, to permit of the esea e of the punchings, as shown in Fig. ii. The under face of the punch block is inclined or beveled upwardly and rearwardly, as at 56, and also provided with a recess 57 on its under face, to receive the shank b of the hook carried by the associated movable set 47 and which opens through the front face'of the punch blockto pprmit of the withdrawal of the punch after t e punching olperation withoutinterference by the hook I s 1 ank. The punch block 54 is provided with a rearward arm 58 having an'elongated slot 59, which receives a stud 60 fixed to the associated slide'49. The anvil 45 of each punch consists of a fiat plate secured to the upper edge of the slide 49, and projects forwardly in its advanced position into the line of movement of the associated punch. By reason of r the pivotal connection of each punch block with its associated slide said punch block is capable of swinging up and down, andowing to the slots 59 lost motion iscreated between the are moved byt-he raceway. The slides and associated parts are retained inthe channels of the plates 49 by cap plates 61, shown in Fig. 4,.and the height of the punch arms 58 rnit of pivotal movement of the punches.- A thin plate 62 of metal is secured to' each 'punch arm under the associated anvil, and this plate is longer than and projects beyond the anvil and is deflected upwardly over the punch asshown in Fig. 13, its outer end betrauce of the material between the punch and anvil. These plates 62 provide work suports and as they move with the anvils are slotted at their free ends, as shown in Fig. 12, to clear the punches.

The forwardly extending arms 46 which slide on the guides 43 and carry the movable designed to be reciprocated in the manner hereinafter described. As shown in Fig. 5, the arms 46 are bifurcated so as to straddle the guide strips 43, and to prevent the arms from being slipped off the guides horizontally the front edges of the latter are enlarged as at 63, thebifurcations being similarly shaped. so as to embrace the enlargements. The movable sets consist, in the present instance, of suitable posts which. are indicated by the numerals 47, each having a depression or (the hook to protect the same from abrasion. The posts are designed to carry-jthe hook holders 65, each of which consists of a plate pivoted at its edge 66 to its associated p est, as shown in Fig. 7.

punch blocks and the slides when the latter is less than that of the channel guides to pering bent downwardly to facilitate the ensets are located under the punches, andare cavity 64 designed to receive the crown of The pivoted edge of the holder is beveled, as at 67,,and cooperating with the angle proile when the holder isin its horizontal the said guides being adapted to move past the sides of the guide strips 43, as shown in Fig. 5, it is provided with a rearward tongue 70 which gradually curves from the plane of the body of the holder. to its end which is at a right angle to the body and in the' lane ofthe bifurcationof the associated gun e 31,- as

projecting upwardly. secured to the sets-l7 at the side opposite the shown in Eigs. 7 and 10, so that as the set ismoved upwardly the tongue of its hook holds-r will ass through the bifurcation and lift the end iook ofi' theguide, which hook movingbygravity will slide along the tongue-and seat in the recess of the holder with itsshank Leaf springs 71 are .t'orining a support for tie arms 46 fixed thereon. As shown in Fig. 2, the rear side of the plate or slide 75 is recessed or cut outto permit of the backward and forward movement of the guides 43. The ends of the plate or slide 75 are provided with 's )acing blocks 76 on which a cross'bar 77 is olted above the arms 46, and by which the movable arms i6 are tied to the slide 75 so as to "be reciprocated by the latter, and at the a same time lateral movement of the arms is permitted to permit of the adjustment of the sets as hereinafter explained.

The slide 75 is reciprocated through the medium. of a lever 78 pivoted between its endsto the standard 21 and the forward end of which ispivotally connected, as at 79, to

the slide 75 while it's opposite end is connect ed to the,,slee've. 80 of a suitable eccentric 81. This eccentric should be ofsucl' character as to advance the movable sets into positionto receive the hooks, then force the sets into engagement with the punches topunch the;

holes, then permit of the retraction of the sets so that the punches may be withdrawn, then advance the, sets into cooperation with the stationary sets, and finally restore the.

movable sets to their original osition, such as that shown and describe in a patent T ,granted to us April 4, 1905, No. 786,340.

Means are provided for simultaneously movin the carriers for the punches and sets lateral y to vary the spacing of the hooks; In the present instance we employ an oscil-' lating or rotating plate which takesthe formof a cylinder 82 mounted upon a shaft 83 located above the adjustable carriers and journaled iii-the brackets 38. This cylinder has a series ofcain slots .84 into which enter studs ofa tend circumferentially of the cylinder, and are arranged divergently, as shown in Fig. 4, in such relation to each other that when the cylinder is turned the punches and setswill be moved simultaneously suchrelative'distances that they will be equally spaced in any posit-i'on ofadjustment. The shaft 83 is provided with a bevel gear 86 which meshes with a similar car 87 on ashaft 8'8 suitably journaled in a caring 89 on the head 36 and provided with a pointer 90 which plays over a graduated dial 91 on the front of the head 36 and designed to be moved by the operator to adjust the parts. The graduations on the dial are such as indicate a certain predetermined adjustment o'rspacing when the pointer is opposite a particular graduation.

In order to adjust the hook guides so that the willfollow the adjustments of the sets ant be in proper positions-to deliver hooks to the holders-of the movable sets in their different adjustments, the pivoted ends of the guides 31 are connected to the carriers-for:

the sets and punches so thatwhen such carriers are adjusted the guides will be simultaneously and correspondingly adjusted. In the present instance th s connection consists ateral pivot pin 92 secured to each pmotcd section 31 of the hook guides'and enteriiig'a groove in a plate 93 secured to an associated guide strip 43. B this arrangement the pivoted sections While connected to the guide strips are capable of pivotal movement at the pivot connection and also of relative longitudinal movement as they follow" the movement of the guide strips The.

grooved plates 93 are of such length as to 'engage thepivot pins 92 in all positions of the raceway.

It is obvious fromthe foregoing that by turning the cylinder 87 the sets and punches of each series will be moved simultaneously and that the spacing between the parts wi I depend merely upon the'ainount of move inent of the cylinder. Furthermore, thatowing to the connection between each ofthe adjustable. carriers and the raceway guides the latter will be correspondingly adjusted so as to always be in pro er relation to holders of the movab e sets.

In order to vary the line of the hooks to the hook conform to. the contour of the edges of dif-.

ferent uppers or to suit the fancy of, the

operator, the plates 41 are adjustable longi-' tudinally and independently of each other.

To this and each plate 41 is provided with a headed bolt 95'entering the plate 40, as shown inFig. 9. 93 the plates 41 may be moved backward or forwardto adjust the associated sets and punches to vary the line or curvature of the ooks when set. In order to insure rectilinear movement of theparts during such adlongitudinal slot 94 through which passes a By unloosening the bolts ju'stment, the plates 40 and 41 may have a tongue in Fig. 4.

At the-beginning of the operation the hook holders 65 are in the inclined position shown in Fig. 1, and the slide 73 in its lower or,de pressed position As the slide, 73 is elevated by the eccentric' 81, the racewayis moved forward by its cam and as it reaches the forward limit of movement, at which time the punches and anvils are in the position shown in Fig. 1, the tongues of the hook holders enter the bifurcations of the hook guides 31 and lift the end hooks therefrom. The.flaring leaves of the bifurcation in the. hook guides insure the entrance of the tongues of the hook holders in the eventthat such tongues are not truly centered with relation to the bifurcations. The hooks-then slide b gravity along the tongues and enter the re cesses in the holders with their shanks up-. ward. T The raceway then begins its retractive movement, and the slide 7 3 continuing its upward movementforces the hook holders against the inclined faces 56 of the punch blocks thereby throwing the hook holders into horizontal position against the posts 47,

when the springs 71 snap past the rear faces of the hooks'a'nd engaging the flanges thereof hold the hooks in position and at the same time assist the springs 68 in preventing displacement of the hook holders. Continued upward movement of the slide 73 brings the portions of the hook holders at the sides of the hooks against the portions of the punch blocks at. the sides of the recesses 64 as in Fig. 11, forcing the punches through the slots of the work-holders 62 and against the anvils end of the slots thereby cutting the hook holes in the m'aterial c, and placing the work holders 62 under tension. As soon as this operation is completed the studs 53 will have reached the in the links 51 and the retraction of the slides 49 and anvils begins.

As soon as the anvils clear the upper sets 42,

the work being still held in position by the engagement of the punches 44 in the holes cut thereby, the spring work-holders 62 springupward stripping the work from the punches and forcing it on the teats-of the stationary sets 42, as shown in Fig. 13. The slide 73 nowfdrops slightly by gravity, owing to theoperation of the eccentric 81, releasing the punch blocks which then drop downward 'into the position shown in Fig. 1.

By this time the studs 60 of the slides 49 will have reached the rear ends of the slots in the arms 58 of the punch blocks, thereby through the agency of the rearwardly moving raceway retracting the punches. The slide 73 new advances again under the operation of the eccentricmoving the movable sets 47 into cooperation with the stationary sets to affix the hooks in the material, after which the,

slide 73 is retracted bythe eccentric to reand groove connection 96, as shown store the parts to their original positions.

The hook holders 65 of the movable sets are restored to their inclined receivin positions by the act of removing the material.
