Specification of Letters Patent.

Patented July 13, 1915.

Application filed August 4, 1909. Serial No. 511,146.

To all whom it may concern:

Be it known that I, RALPH C. SIMMONS, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Hook and Eyelet Setting Machines, 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 eyelets, lacing hooks or studs, rivets or similar fasteners, and more particularly to machines for setting two different kinds of fasteners, as eyelets and lacing hooks, in boots and shoes.

An important object of the invention is to provide a machine for setting two kinds of fasteners of the characters referred to which vide, in such. a machine, automatic mechanism to stop the operation of the fastener setting devices after a predetermined number of either kind of fasteners has been set, and which is furthermore, under manual control, whereby the operation of such devices may be stopped at any point desired by the operator independently of the auto matic mechanism. In connection with this feature of the invention, if the machine is constructed to set eyelets and lacing hooks, the arrangement is such that the numberof either of these fasteners which the machine will set may be controlled by the operator.

Another object of the invention is'to provide, in a machine of the character referred to, means for determining the distance that the eyelets and the lacing hooks shall be set from the edge of the stock, which. means is automatically controlled in such manner that the eyelets may be set at a different distance from such edge than the lacinghooks, and, if desired, certain of the eyelets may be set at a greater distance from such edge than other eyelets. Preferably, the means referred to includes a gage whose location to variably determine the position of theedge of the stock relatively to the setting devices is governed by any one of a set of pattern cams which are under the control of the operator.

The invention is shown as embodied in a machme' provided with a setting device for eyelets and a setting device for lacing hooks, and a feature of the invention consists in proyldmg in connection with each of such devlces a coiiperating anvil, and two punches, one of a size appropriate for eyelets and the other of a size appropriate for hooks, the punches being so arranged that either of them may be positioned over the punch anvil and the mechanism will act to cause the punch which is in operative position to first move downwardly to punch the stock, and to then move laterally to feed the stock the proper distance to locate the punched hole under the eyelet set, or the hook set, as the case may be.

In connection with the mechanism that efi'ects'the setting of a predetermined number of eyelets and a predetermined number of lacing hooks, the machine embodies automatically operating devices which are so constructed as'to move the eyelet punch into operative relation with, its anvil and the hook punch out of operative relation therewith when the eyelet set is rendered operative andthe hook set is rendered inoperative, and vice versa. As the eyelet set and the hook set respectively, occupy different lateral positions relatively to the position occupied by the punch which may be in operation, mechanism is provided for automatically changing the terminal point of the punch in feeding the stock, so that such point will be located in line with the eyelet setting plunger when eyelets are to be set in the stock, and in line with the hook set ting plunger when hooks are to-be set therein. Preferably this mechanism includes an adjustable member connecting a feed slide, or table, with the ,carrier for the punch the member being actuated in such manner as to move the punch-carrier in one direction relatively to the feed slide prior to the operation of the eyelet set, and in the opposite direction prior to the operation of the hook set.

As it is frequently desirable to space the hooks a given distance apart on the stock and the eyelets a different distance apart, it being the usual practice to set the eyelets closer together than the hooks, a feature of the invention lies in the provision of an improved mechanism, automatically controlled, for determining the distance that these fasteners shall be spaced from one another when set, such mechanism being also under manual control, whereby the operator may, under one adjustment, so influence the automatic mechanism as to vary the spacings of the fasteners controlled thereby, and under another adjustment may vary such spacings in a manner which will be wholly independrendered operative the hook setting devices are rendered inoperative, and vice versa. In the preferred construction, a plurality of locking devices are arranged in connection with the plungers carrying the setting devices and their anvils in such manner that when the .locking devices are moved in one direction the eyelet setting device and its anvil are locked to the actuating members, and the hook setting device and its anvil are locked to the frame of the machine; and when the locking devices are moved in the opposite direction the hook setting device and its anvil are locked to the actuating members, and the eyelet setting device and its anvil are locked to the frame of the machine.

Another feature of the invention comprises an improved arrangement for supporting the hopper for containing the eyelets,

whereby it may be rocked or oscillated, together with its raceway, to enable the settingdevice to pick the eyelets from the end of the raceway as it moves toward setting position, the parts being so constructed as to permit the hopper and raceway to be easily removed in order that another hopper and raceway adapted for a different size or style of eyelets may be substituted therefor.

Other features of the invention, including important combinations of parts and details of construction, will be hereinafter more specifically described and claimed.

The numeral 252 indicates the main frame or casing which supports, and partly incloses, the several elements of the machine herein shown as embodying my invention. The frame sustains, in suitable bearings provided therefor in its front portion, (see Fig. 5), a power shaft 1 to which are keyed or otherwise fastened a number of cam disks having grooves or ways for operating the clutch, the presser foot, the eyelet raceway, the punch, the hook-releasing lever, the setting devices and the feeding mechanism. i

The power shaft also carries the clutch member 231, and the loose pulley 232. All of these parts will be referred to and more pa rticularly described hereinafter.

Suitably located in hearings in another ite-pas part of the frame, preferably to the rear of the power shaft 1, (see Figs. 6, 7 and 8), is a shaft 8, carrying a number of gears 11, 12 and 13, which mesh with a like number of gears on a shaft 253, forming part of a train connecting a gear 23 on the shaft 1 with the gears 11, 12 and 13. The shaft 8 carries six sets of pattern cams, designated, respectively, by the letters a, b, a, d, e and 7", each of which, in the machine illustrated, comprises three cams so designed as to effect in the mechanism controlled thereby, as will be hereinafter described, a defi nite operation. These cams are herein shown as being in the form of thin disks and are fastened rigidly to the shaft by a series of spacing collars, or equivalent means, through a key 10, so as to rotate therewith. The shaft 8 is mounted for longitudinal sliding movements in its bearings in the frame 252, and in the three gears 11, 12 and 13, and carries a feather key let, whereby, when the shaft is moved to position any of the pattern cams in the sets that may be selected to impart certain predetermined operations to the several mechanisms, opposite their appropriate cam levers, the feather key will enter a cooperating recess in that one of the three gears which has a suitable number of teeth to cause the shaft 8 and its cams to rotate at the proper relative speed to the shaft 1. I

The shaft 8 and pattern cams are manually movable in a longitudinal direction through a lever 15, pivoted to the frame at 19, and having its inner end forked to embrace the end of the shaft, which is provided with an abutment outside of the forked end of the lever. The outer end of the lever is formed as a handle, and has pivoted thereto at 20 a latch lever 16, carrying a pin 17 to cooperate with a series of holes 18 in a bracket fast to the frame of the machine, whereby the lever may be held in any one of the three positions to which it is moved in longitudinally adjusting the shaft S and the pattern cams. The pattern cams are so formed that at one point in all the cams the distance measured from the center of the shaft diametrically outward is the same, and, when the shaft in its rotation carries the cams so that this point coincides with the several cam levers, the parts are in position to be shifted longitudinally. In order to insure that it shall be shifted at this point the shaft 8 is provided with a series of disks 9, which are fast thereto, and have in their peripheries a series of alincd openings arranged to register with a plate 21 secured to the frame by a screw 22, when the shaft has reached the position appropriate for such longitudinal movement. At any other point in the revolution of the shaft the plate 21 will lie in one of the spaces between the adjacent facesof two of the disks, and hence prevent any shifting of the shaft.

The gear 23 is mounted on a hub whichcarries an internal spline or feather 2 1, to enter a groove in the shaft 1 in order that it may be constrained to rotate with the shaft, while being free to slide longitudi-' if the gear 28 is moved out of mesh, the

shaft 8 and pattern cams are free to be rotated manually, which, under certain conditions, may be found desirable. In order to effect this operation a lever 28 is secured to the end of the shaft 8 by a nut, as shown, and has one of its ends connected by a spring 30 to a fixed point on the frame of the machine, and its opposite end connected, through a rod or other suitable connection 29, with a treadle, or equivalent operating device. A plate 31 is secured to a collar on the shaft 8 to cooperate with a pin 32, which is slidably mounted in the bracket to which the plate 21 is fastened. When it is desired to rotate the shaft manually by the lever 28 the pin may be projected so as to intersect the path of movement of the plate 31, the arrangement of these parts being such that afterthe shaft 8 is rotated sufliciently to cause the pattern cams to actuate the mechanisms controlled thereby, the treadle may be released and the spring 30 will act to rotate the shaft reversely and restore it to its normal position of rest, the plate 31 coming in contact with the pin 32 to prevent further rotation of the shaft when it reaches the position where the openings in disks 9 aline with the plate 21. The spring 80 and treadle rod 29 are in free detachable engagement with the ends of the lever 28, as by means of hooked terminals which enter apertures in the lever, whereby, when the shafts 1 and 8 are to be connected through the train of gears in order that the pattern cams shall be caused to operate automatically, the spring and rod may be disconnected from the lever and the latter will simply turn idly as the shaft rotates.

With the construction above described, the operator may, by a few simple manipulations, connect the pattern cams with the power shaft of the machine in order that they may be operated automatically in timed relation with the parts whose operations are controlled by the cams carried on the shaft 1, or he may operate the pattern cams through any desired arc of movement independently of the movements of the parts controlled from the shaft 1. I

Referring to Figs. 1, 4, 7, 10, 11 and 12, the hub carrying the gear 23 is provided with a fast pulley 249, which, through a belt 250 and fast pulley 251, serves to rotate a short shaft mounted in bearings on the frame of the machine and carrying a onetoothed gear 271, which meshes with a gear 253 fast on a shaft 254. This shaft-carries a picker plate 66, in a hopper 65, which is supported on the frame of the machine and may contain lacing hooks. The shaft 254 is journaled in and extends through the hopper and upon its end is secured a bevel gear 255, which meshes with a bevel gear 256, secured to the end of a shaft 257 ,joure naled in and extending through a hopper 40, to contain eyelets, said shaft carrying, within the hopper 40, a picker plate 45. The frame 41 of this hopper isconstructed at a suitable point in its periphery with a socket 43, and at another point, diametrically opposite thereto, with a projection 42,

to cooperate, respectively, witha pin 44 movably mounted in a bracket which projects from the machine frame, and a socket 420, formed in another bracket which also projects from said frame, said parts constituting pivotal bearings for the hopper 40. As the centers of the pin 44 and socket 420 coincide with a line whose direction is inclined to the base line of the hopper 65, the hopper 40 will be sustained angularly thereto, as'shown in Fig. 10. The raceway 50 is rigidly secured to its hopper 40, and upon removal of the pin 44 from the socket 43, the hopper may be lifted from the socket 420, and another hopper and raceway, adapted for a diflerent kind or size of eyelets, substituted therefor.

The eyelets which are to be fed to the eyelet setting devices are separated from those in the bottom of the hopper and discharged into the raceway 50 by the picker plate 45, whose construction may be the same as the picker plate used for the lacing books. The bottom 46 of the hopper is preferably externally threaded as shown at 47 (Fig. 12), to engage an internal thread in the frame 41, in order that the space between the picker plate and the bottom of the hopper may be adjusted to agree with the size of any desired eyelet, it being understood that the'flanges of some eyelets are thicker than others. The picker plate being caused to revolve through the connections described, eyelets will be carried up on that part thereof indicated by the numeral 48, and those whose flanges have not been caught between the bottom of the hopper and the plate will, owing to the inclination of the hopper, fall back into the lower part thereof. The eyelets which have been caught by the plate will roll or slide along the edge 48 until they reach the eyelet-guide 49, which is constructed and arranged to direct them onto the raceway. As each edge 48 of the picker plate reaches a position in line with the lower side of the raceway, the onetoothed gear 271 becomes disengaged from the gear 253, which results in a period of rest in the turning movement of the plate sutlicient to permit the eyelets to slide therefrom onto and down the raceway to the spring-actuated finger 51 at the end thereof, which holds the eyelets back until they are picked off of the raceway by the spindle of the eyelet set. To prevent the eyelets from becoming jammed at the raceway entrance, a yielding spring-actuated member 52 may be located at this point, as shown in Fig. 11.

Referring to Fig. 1, the eyelet set 258 is provided with a cap 265, having therein the usual setting depression, and through which projects the spring-pressed eyelet spindle 264. The eyelet set has a forked portion to embrace the upper end of its plunger 120, to which it is pivotally connected at 260, and an angularly disposed arm or extension carrying a roll 261, which fits in and is guided by a cam slot 262, having a vertical portion and an inclined portion as shown, in a plate 263 secured to the machine frame.

The eyelet raceway 50 and hopper 40 are caused. to swing on the pivotal bearings heretofore described by a lever 53, Fig. 2, having a forked end which engages a projection 54 on the raceway, the lever being shown as pivotally mounted on a pin 55, carried by a collar 56, which is clamped or otherwise secured to a pin 57, or other suitable support carried by the frame of the machine, the lever deriving its motion from a cam way or groove 4 in a cam which is fast on the shaft 1, see Fig. 5. The described movements imparted to the eyelet raceway cause it first to be moved toward the eyelet set so that its end portion passes down and over upon the spindle 264 thereof, when the set occupies the inclined position as shown in Fig. 1, just prior to the operation of setting the eyelets in the stock, which impales on the spindle the lowest eyelet in the raceway. That side of the raceway which is uppermost when the parts occupy this position is cut away for a short distance from the lower end of the raceway, as shown in Fig. 2, on a line substantially parallel with the plane in which the eyelet set swings upward when it moves about the center 260, to permit the set to remove the lowest eyelet from the end portion of the raceway, it being understood that said eyelet rests against a suitable stop which retains ituntil so removed. Following the describedmovement of the raceway the eyelet plunger rises, during which movement the action of the cam 262 on the roller 261 turns the eyelet set from an inclined to a vertical position, thereby withdrawing the eyelet on the spin- .1,14.e,o2a a die from the lower end of the raceway, and the continued rise of the set carries the eyelet to the point where it enters the hole made in the stock by the punch, and is clenched by the anvil cooperating with the eyelet set. During the last portion of the upward movement of the eyelet setthe raceway is swung in a direction contrary to that above described, in order to be in a position to repeat the operation.

The lacing hook-containing hooper 65 is, as shown in 10, supported by the frame of the machine in a position to the right of the center thereof, and an extension of the frame serves as the bottom or back of the hopper. The rotatable shaft 254 carries the picker plate 66 within the hopper, whose construction and mode of operation may be substantially the same as the picker plate 4.5. The numeral 259 indicates the lacing hook raceway which conducts the hooks from the hopper 65 to the hook setting device 80. A hook separator 67, shown in Figs. l, 16, and 18, is supported for oscillating movements in bearings 68 carried by a bracket secured to. the raceway 259, and is connected, through a lever 69 and links 70, with a cam lever 71 pivoted to brackets on the machine frame. The cam lever 71, as shown in Fig. 4, is provided with a camway within which plays a pin or roll 72, carried by the hook set plunger 7 3, the camway being so shaped that the plunger descends after setting a hook, the pin will impart an oscillating movement to the separator to release a hook and permit it to slide down the raceway under an arm 74 (see Fig. 13), the separator at thesame time moving in front of the next succeeding hook to prevent its release.

The arm 7 4 is provided with a supporting stem 76, preferably integral therewith, which is journaled for axial turning move ments in the front plate 7 of the machine frame, and carries at its lower end a disk 77 whose lower face is provided with a camrise or enlargement. This disk is sustained bv a pin 78. secured to the frame, against the thrust of a spiral spring 79, which may surround the stem 76. As the arm 74 is moved in a backward direction, by mechanism to be hereinafter described, the cam face on the disk 77 acting on the pin 78 will cause the arm to rise and pass over the hook which has just been released by the separator 67. such hook being then in the position indicated by the numeral. 104% in Fig.

18, and permit it to slide under the arm. The hook moves underthe force of gravity suilicientlv far. beyond the arm 71 to reach a position on the raceway where it will be caught by the arm in its neXt forward and downward movement, and be swept on to the hook-supporting plate of the hook set 89, which is provided withv a vertical wall 81 to arrest the movement of the hook and properly locate it thereon.

The hook set has a pivotal connection 82 with its plunger 73, and the plunger is formed with a recess which contains a spring-actuated bolt 95 to act upon the erd of the hook set with a normal tendency to hold it in vertical alineinent with its plunger. The plunger and set are guided for vertical movements toward and from hook-receiving and hoolesetting positions, in grooves which are formed partly in projections 83, 84. and 85 on the front plate of the machine frame, and partly in caps 86, 87 and 88 which cover and are secured to said projections. also serves as a sustaining member for the work support, which comprises the lower and upper plates, 89, 90.

The upper plate 90 of the work support is provided with a transverse groove or way, as shown in Figs. 15 and 18, in which a slide 91 plays, the slide having guiding flanges to rest upon shoulders formed along the sides of the groove, and having also in its front wall a recess 93 whose sides converge upwardly and inwardly. A pin 93, attached to the slide, extends rear-wardly through a bore in the plate 90 where it terminates in a head, the pin being surrounded by a spiral spring 92 which is confined between the plate and slide and acts to yieldingly press the slide forward until checked by the action of the head of the pin against the rear wall of the plate. By this construction, when the hook set rises from its hook-receiving position at the end of the raceway, as shown in Figs. 1, 13, and 1a, to its hooksetting position, as shown in Fig. 18, the hook carried on the plate of the set engages the recess 93 in the slide 91, which yields slightly, and acts to properly aline the hook with reference to the hook set anvil, and to hold it accurately in position while it enters the punched. hole in the stock, and until the completion of the setting operation.

Referring to Figs. 3, 5, 7, 13 and 14-, the numeral 97 indicates the hook-releasing le ver which is pivotally supported on a stud 98, fast to the frame of the machine, and has secured to its upper end a finger 96, the lever carrying a cam roll to enter a cam way 9 in a cam disk fast on the shaft 1, whereby it may be oscillated to cause the finger 96 to tilt the hook-set outwardly and disengage it from the hook after the setting operation, as will. be more fully explained hereinafter. In the upper part of the lever 97 a pin 99 is pivotally mounted. and, as shown, the pin has a forked end whose two members are apertured to receive a swiveled stud 260 which is provided with a transverse aperture to receive the stem of a link. 100, sliding freely therein. The stem of link 100 is surrounded by aspiral spring 103 which is confined beso The upper cap, 86,

tween a washer at one end of the stem and the stud 260, and the opposite end of the link is forked, and the members thereof apertured to receive a pin 102, which passes therethrough and through an eye in a stud 101, which is received in said forked end, the stem of the stud 101 fitting an opening through a sleeve or extension of the arm 7 4. The members of the forked end of the link are suflieiently spaced from the eye of the stud 101 to permit the required amount of lost motion necessitated by the rising and falling movements of the arm. I Referring to'the parts just described, im-

mediately after a hook has been set the arm 97 moves forward, causing the finger 96 to engage the set 80 and tilt it, thereby disengaging the set from the hook, the arm in such operation imparting, through the con nections described, an axial turning movement to the stem 76, which, through the ac tion of the cam disk and pin, is lifted as it turns and carries the arm 7 4: upwardly and back to the position shown in Fig. 13. The plunger 73 and hook set 80 then move downwardly until the set reaches a position opposite the end of the raceway (Fig. 13), the cap 86 being cut away, as shown in Fig. 1 to permit the set to clearthe end of the finger 96, thereby, through the action of the pin 72 on the cam lever 71, causing the separator to release another hook, during which movement the lever 97 remains forward and the finger 7/1 occupies a raised position above the raceway, permitting the released hook to slide beneath it, as shown at 104, Fig. 13. The lever 97 then moves to its rearward position, causing the arm 74 to move forwardly and downwardly to sweep the hook on to the hook-supporting plate of the set. In the event of there being any obstruction offered to the movement of the arm during this operation, as, for instance, if a hook should reach its final position of rest against the wall 81 of the set before the lever had completed its backward movement, the spring 103 would yield and permit the lever to complete its'backward movement. The set then rises from its position opposite the end of the raceway and carries the hook into engagement with the slide91, which serves to aline and properly position the hook as its barrel rises through the opening in the work support and enters the aperture made by the punch in the stock, and thereafter the anvil engages the hook and coiiperates with the set to clench it in the stock.

Referring to Fig. 1, the numeral 73 indicates the hook-set plunger which is arranged to cooperate with the hook anvil plunger 122, and 120 indicates the eyelet set plunger whichis arranged to coeperate with the eyelet anvil plunger 121, said plungers being guided in grooves or ways formed in the frame of the machine in whichthey are retained by caps 86, 87, 88, 123 and 124. In order that the eyelet set and anvil plungers may be reciprocated simultaneously in opposite directions to set eyelets, or the hook-set and anvil plungers may be so operated to set hooks, I have, in the present embodiment of the invention, provided two driving blocks, 125 and 126, the former of which is connected through a link 15 1, bellcrank lever 152 and link 155, and the latter through a link 151, respectively, with the opposite ends of a cam lever 148, pivoted to a stub-shaft 150 in the frame, and deriving its motion from the cam way 6 in a cam disk fast to the shaft 1. The driving blocks are, through the mechanism described, simultaneously reciprocated in opposite directions, and when connected to the plungers carrying the eyelet set and its anvil, or to the plungers carrying the hookset and its anvil, serve to impart to these parts the necessary movements to cause them to set the fasteners in the stock.

The driving blocks are provided with vertical grooves to receive, and slidingly engage, the plungers, to which they are confined by the caps 127 and 128, respectively. The caps 123, 127, 128 and 88, and the adjaeent portions of the machine frame and of the driving blocks to which these caps are secured, are provided with transverse grooves to receive, respectively, the locking keys 129, 130, 131 and 1.32, whose construction, and mode of operation in the several positions they assume in locking the plungers to the driving blocks and to the frame of the machine, are illustrated in Figs. 19 to 22, inclusive. The keys are formed, as shown, with cut out portions or recesses whose edges are designed to engage with notches formed in the several plungers, and are so located that when the keys are moved simultaneously in one direction the plungers carrying the eyelet set and eyelet set anvil are locked to the frame, while the plungers carrying the hook set and hook set anvil are locked to the driving blocks, and when they are moved simultaneously in the opposite direction the plungers carrying the eyelet set and eyelet set anvil are locked to the driving blocks while the plungers carrying the hook set and hook set anvil are locked to the frame. Fig. 19 shows the position of the keys 130 and 131 in locking the plungers 121 and 120 to the driving blocks 125 and 126, and Fig. 20 shows the position of the keys 120 and 132 in locking the plungers 73 and 122 to the frame, following a simultaneous movement of the keys toward the right. Fig. 21 shows the position ofthe keys 130 and 131 in looking the plungers 7 3 and 122 to the driving blocks 125 and 126, and Fig. shows the position of the keys 129 and 132 in looking the plungers 121 and 120 to the frame, following a simultaneous movement of the keys toward the left. The keys are formed with openings 267, at or near their ends, to receive pins, 133 and 131, the former of which carries arms 13% and 135, fast to a rock-shaft 133 journaled in the upper part of the frame, and the latter carries arms 136 and 137 fast to a rock-shaft 139, journaled in the lower part of the frame, as shown in Figs. 1 and 23, the keys 130 and 131 being capable of sliding freely on these pins. The pin 133 is connected by a link 140 to an arm 14:2, and the pin 13 1 bya link 11-1 to one arm of a bell-crank lever 1.43, which arm and bellcrank lever are fastened to a rockshaft 1 1 1 jouiinaled in the frame of the ma chine. The opposite arm 145 of the bellcrank lever is connected through a link 147 with the cam lever 146 (Fig. 23) which carries a roll and is held by one of a series of springs 248 in engagement with the periphery of one of the pattern cams f, on the shaft 8. this arrangement, the pattern cams f, which are variously designed, will control, automatically, the positions of the keys and thereby determine the time when the eyelet setting devices are rendered operative and the hook setting devices are rendered inoperative, and vice versa. The operator may shift the shaft 8 through the lever 15,.and move any one of these cams to a position where it will control the lever 1. 16, in accordance with its patterned surface, to cause the machine to set a given number of eyelets and then set a given number of lacing hooks, and the machine will continue to alternately set the numbers of these fasteners thus predetermined by the shape of the cam, without any further attention on the part of the operator. Elliould, however, the operator desire to change the number of the fasteners to be set by the machine, the shaft 8 may be shifted to locate any other one of the cams opposite the lever 14:6, and the number of eyelets and lacing hooks that the machine will set will then be governed. by the patterned surface of that particular cam.

Referring to Figs. 3, 9, 9 and 9 which represent the punching mechanism, the numeral 159 indicates a hollow stud which is rigidly secured to the frame of the machine in any suitable manner, as by a nut, as shown, and 166 and 166 the two members of a punch carrier which surround and are free to rotate on the stud. The lower member of the carrier is extended toward the front of the machine and provided with an anvil 174, for the punches, and the upper member has rigid therewith an arm 191..

Both members of the carrier are formed with alined openings having bushings to afford bearings for a plunger 1641, which may slide and turn freely therein, the plunger also passing through an opening in the punch holder 162, to which it is rigidly secured by a pin 165. Two punches, 160 and 161, the former being of a size of and adapted to make holes in stock suitable for one kind of fasteners, as eyelets, and the latter of a size to make holes in stock suitable for another kind of fasteners, as lacing hooks, are clamped, respectively, to two arms extending from the hold r, by screws 163, or equivalent means. The plunger and punchers carried thereby are caused to re ciprocate through a link 172, which is connected by a ball and socket joint with the plunger, and pivotally with a lever 169, fulcrumed at 170 to the carrier, a rod 171 having one end in rotative engagement with a sleeve pivoted to said lever and its opposite end pivotally connected with a cam lever 167, fulcrumed on a shaft 168, said lever carrying a cam roll which enters a cam way or groove 5 in a cam disk fast on the shaft 1.

Surrounding the upper member 166 of the carrier, and turning freely thereon, is a collar carrying a segmental gear 173, which meshes with a segmental gear 3.45, formed on the rear part of the punch holder 162, and secured to this collar by a pin 175 is another collar having thereon a beveled segmental gear 176, which meshes with and is driven by a beveled segmental gear 177, carried by a bell-crank lever 277, which has a sleeved extension to fit and turn freely on a stem 178. The stem 178 is fast to or integral with the upper member 166 of the carrier, and the sleeve of the gear 177 is confined to the stem by a screw and washer 179, as shown. Extending from this sleeve is an arm carrying a second sleeve within which is pivoted the stem 278 of a forked member 180 whose arms embrace, and slide freely along, a sleeve 181, rectangular in cross section, and which is pivotally mounted on a pin 1823 held. between the forked ends of one are of a lever 183. The lever 183 is fulcrumed on a stud shaft 184:, secured to the frame, and derives its motion from one of the pattern cams 5, through a cam lever 1.85, to which its other arms is connected by a link 186.

When the punch carrier is moved about the hollow stud 159, through the feeding mechanism, which imparts an angular motion to the punches, to feed the stock, the position of the punches relatively to the anvil 174 remains unchanged as long as the vertical position of the sleeve 181 is not varied, and the forked member 180, during such movements, slides along the sleeve; when, however, that point in the cycle of operations of the machine is reached where the eyelet punch is to be rendered operative, and the hook punch is to be rendered inoperative, or vice versa, one of the cams b will actuate the cam lever 185, and, through the connections described, the sleeve 181 and forked member 182 will be raised or lowered, and the punch holder turned, to the right or to the left, to locate the desired one ,so located that one of said holes will be under the hook set.

entered by a dowel pin as the holder descends, and thereby accurately center the punch.

The mechanism for impart-ing the feeding movements to either one of the punches while it occupies the punched hole in the stock, is illustrated in Figs. 5, 7, 23, 24 and 25. The arm 191 of the punch carrier is connected, through a link 192, with a pin 195, eccentrically mounted at the end of a shaft 193, which is journaled in a feed slide 194. When the shaft 193 is turned to move theeccentric pin 195 toward the front of the machine, as shown in Fig. 7, and the feeding movements are imparted to the punch by the slide 194, through connections to be described, the punch will be located, at the termination of such movements, under the eyelet set. If, however, the shaft is turned reversely to carry the pin to a rearward position, the punch will be located, at the termination of the feeding movements, These changes in the location of the punch at the final point in the forward stroke of the feed slide are effected automatically, and through mechanism' which is controlled by one of the pattern cams d, it being understood that the parts are so timed that the feeding movements of the punch will be made to terminate under the setting device which is then in operation. The shaft 193 carries a pinion 270 which'meshes with a rack 196 having a bearing in the feed slide 194. A squared block enters a slot in the rear part of the rack to which it is pivotally connected by a pin 200, and a bell-crank lever 197, having its fulcrum at 198, on a link 199, has its upper end forked to embrace the squared block to which it is pivotally connected, and its lower end connected, through a link 201, with a cam lever 202, carrying a roll for cooperation with one of the pattern cams cl.

The feed slide 194 is pivotally supported on two links, the forward one of which, 205, rocks upon a stud shaft 204 fast to the frame, and the rear one, 199, rocks upon a stud thereby. manually, if desired, independently of the shaft 203, also fast to the frame. The link 205 is slotted and a cam lever 209 pivoted at one end to a stud shaft 211 fast to the frame, and carrying at its opposite endaroll to enter a cam way 7 in a cam disk on the shaft 1, is similarly slotted. A pin 206, upon which are pivotally mounted two rectangularshaped blocks, is located in the slots in the links, along which the blocks have a sliding engagement. The outer end of this pin is extended, and connected thereto by a link 207, is a lever 208, fulcrumed to the shaft 247, said lever having one arm rearwardly extended and provided with a roll to cooperate with one of the pattern cams c, and its other arm forwardly extended to form a handle 214, as shown, and passing through a slot in the front of the casing where it is in convenient position to be grasped by the operator, as shown in Fig. 1.

The extent of the angular motion which the cam way 7 imparts to the lever 209 is invariable, but the amount of such motion which is transmitted to the feed slide through the pin 206 and link 205 is made variable by the adjustment of the pin along the slots in the lever 209 and link 205. By this means, the extent of the feeding movements imparted to the punches by the described connections may be controlled, in order to vary the spaces between the fasteners as they are set in the stock. It is sometimes found to be desirable to set the eyelets a different distance apart than the lacing hooks, and, for different kinds of work, to set either or both of these fasteners atvarying distances from each other. To this end, the pattern cams 0 may be so designed as to govern the spacings desired for a number of different kinds of work, and when one of these cams is located opposite the lever 208, the spacing will be automatically controlled The spacings may be controlled pattern cams, through the handle extension 214 of the lever 208, the limits of whose movements in opposite directions are shown as being capable of adjustment by two pins 213, each to be located in any one of a series of holes formed in a bracket 212, secured to the frame.

Referring to Figs. 7, 18, 24 and 25, the edge gage 215 is shown as formed of two parts, which may be connected by a screw and dowel pins, as indicated at 216, the gage being controllable as to its position in order to determine the distance that the fasteners will be set from the edge of the stock, by one of the pattern cams c, acting on a cam lever 217, which is connected with the edge gage. The pattern cams may be designed to vary the distance from the edge of the stock at which the fasteners are to be set in any manner desired, so that the eyelets will be set at one distance from said edge, and the lacing hooks at a difierent distance therefrom, or so that both kinds of fasteners will be set at the same distance from said edge. Preferably, the edge gage should occupy a position immediately to the rear of the setting device which is in operation, and as the eyelet set and the hook set are located side by side, it is desirable to move the gage laterally to its proper position back of each set prior to the beginning of the operation of the set. To this end, a carrying palte 218 is provided, which is connected at one end by an eccentric pin 219 and crank arm 220, with the shaft 193, and is guided near its opposite end between two pins, 221 and 222, which are fast to the frame of the machine. The carrying plate supports the edge gage, and is provided with two spaced pins 223 and 2241-, between which the gage is confined against lateral movements, but is free to slide longitudinally. By this construction, the partial rotation imparted to the shaft 193 to alter the terminal point in the feeding movements of the punch will simultaneously move the carrying plate, and through such plate the edge gage, to the right or to the left, to thereby locate the gage to the rear of the setting device then in operation.

The presser-foot 225, as shown in Fi 2, is preferably curved and may be secured by a screw 227, or equivalent means, to a pin 226 which is guided for reciprocating move ments in openings formed in the frame of the machine. A spring 229 surrounds the pin 226, and is confined between a projecting part of the frame an d the top of the presserfoot with a normal tendency to force the presser-foot toward the work support. The presser-foot is guided by a pin 228 which is fast to the frame and enters a hole in the presser-foot. The lower end of the pin is provided with a foot 230 which is held by the spring 229 in engagement with the surface of a cam, fast on the shaft 1, and having an elevation 3 which is so located as to raise the presser-foot from the i work during the feeding movements of the punch.

Referring to Figs. 5 and 6, the clutch is shown as comprising the member 231 having oppositely beveled surfaces, and formed with an aperture of square, or similar cross section, to fit a square portion of the shaft 1, whereby it may slide thereon, but is constrained to rotate with the shaft. An eX- tension of this clutch member is grooved to receive two inwardly extending projections from the forked end of a clutch-actuating lever 236, which. is pivoted at 237 to a bracket secured to the frame of themachine. The loose pulley 232 is rotatively mounted upon a sleeve 233 to which it is confined against longitudinal movement between a collar at the inner end of the sleeve and a washer,

or similar locking device, 234;, held fast against the outer end of the sleeve bythe head of a screw-bolt 235, having a shank to enter a threaded hole in the end of shaft 1. The sleeve 233 is provided at its outer portion with an internal screw-thread which engages an external screw thread. on the end of the shaft 1, whereby the loose pulley, together with the sleeve which constitutes its hearing, may be removed bodily from the shaft, or adjusted longitudinally thereon. The sleeve is practically the same length as the hub of the pulley, and when the washer 23 1 is clamped against the end of the sleeve by the screw-bolt the sleeve will be locked securely to the driving shaft and will be prevented from rotating relatively thereto. As

shown in Fig. 5, there is a space between the extremity of the driving shaft and the washer which is sufficient to permit a certain amount of adjustment of the sleeve and pulley toward the clutchmember.

The oppositely disposed beveled or inclined surfaces of the clutch member cooperate, respectively, with like surfaces on the inner face of the loose pulley, and on the frame of the machine. When the clutch member is moved in one direction it engages with the loose pulley and the power conveyed by the usual belt to the pulley is then applied to the shaft 1; and when the clutch member is moved in the opposite direction, it disengages from the loose pulley and engages with the beveled surface on the machine frame, which acts as a friction brake and stops the rotation of the shaft. A. spring 238, which is confined between a fixed part of the frame and anarm of the lever 236, acts to normally move the clutch mem her in a direction to engage the loose pulley. A cam lever 239 is pivotally supported from a link 267, which is pivoted to a bracket fast to the frame and carries two oppositely eX- tending arms 269, which bear against two set screws 27 3, whereby the lower end of the link, and thelever carried thereby, may be adjusted laterally with respect to the face of a cam 2, formed on a cam-disk fast onthe shaft 1, and at an intermediate point the lever carries a roll which normally engages the face of this cam. A trip 240 is pivotally connected at one end with the lever 239, and

at its opposite end is curved to correspond with the surface of a roll 242, journaled in the end of the clutch-actuating lever 236. The trip has attached to it at an intermediate point a treadle rod, or equivalent connection 241, in order that it may be actuated manually to disengage its free end from the roll 2 12, and a spring (not shown) acts upon the release of the treadle to move the rod 24:1 reversely to cause the trip to come into engagement with the roll. With the parts of the clutch mechanism as thus far described, it willbe obvious that if the I operator steps on the treadle connected with 242, and the trip will assume the position 7 shown in dotted lines, Fig. 5, thereby permitting the spring 238 to act, and, through the lever. 236, to force the clutch member into engagement with the loose pulley and cause the shaft 1 to rotate; and if the treadle is released the trip will, again move into engagement with the roll, so that when the shaft "has made one complete rotation the cam 2 will reversely actuate the clutch member to set the friction brake and stop the retation of the shaft, unless otherwlse pre- 2 vented.

The number of teeth in the several gears constituting the train connecting the shaft 1 with the shaft 8 are so proportioned to each other that the shaft 1 rotates a plurality of times for each single rotation imparted to the shaft 8, and in order tocomplete a cycle of operations of the machine, during which a predetermined number of eyelets and a predetermined number of lacing hooks are set. in the stock, it is necessary that means be provided to prevent the clutch from being actuated when the treadle is released until the shaft 1 has made the required number of rotations to set the desired number of fasteners. To this end, a cam lever 248 is pivoted tothe shaft 247, and carries upon one arm a roll to be held by a spring 248 in engagement with the surface of any one of the three pattern cams a, and has pivotally connected with its other arm, a latch 244, which is arranged above the trip 240. When the trip is moved out of engagement with the roll 242 to start the machine, and the shaft 8 begins to rotate, if the treadle is released the pattern cam then in operative relation with the lever 243 will effect a depression of the latch and cause its end to engage a shoulder on the trip and prevent the trip from reengaging the roll 242 until the pattern cam reaches a point where it causes the lever243 to raise the latch and permit such action. The cams a may be of difi'erent designs in order to provide for stopping the machine any number of times during'a cycle of operations, as may be desired,

according to the character of the work. If,

for instance, the machine was adjusted for setting automatically a predetermined number of eyelets and a predetermined number of lacing hooks, it would be desirable to have the cam a which was in operation so designed asto cause the machine to stop twice, that is, once immediately after all of the first one of these kinds of fasteners had been set, and again after the last fastener had been set in thestock.

While the cams a are, in practice, so designed as to permit the clutch mechanism to bring the machine to a stop automatically at such times as may be best suited to most conditions of work under which the machine may operate, it is sometimes desirable to stop the machine before the cam a reaches the point to raise the latch 244. For this purpose, a lever 245, which is pivoted to a stud 246 fast to the machine frame, is arranged to extend along the side of the latch and to project through an opening in the front of the frame, within convenient reach of the operator. To stop the machine, the operator moves this lever to one side so as to swing the latch off from the shoulder on the trip, thereby permitting the trip to rise and its end to engage the roll 242, so that the cam 2 may, through the connections described, effect a shifting of the clutch member to set the brake and stop the machine. The lever 245 is then returned to its original position, and the latch swings back to lie vertically, and is thereby properly located to act again upon the trip, when the same is depressed through the treadle, and to hold it away from the roll 242 until it is released through the automatic action of the pattern cam.

While the machine as herein illustrated is provided with setting devices, raceways, and hoppers that are so constructed as to set lacing hooks and eyelets in stock, it is to be understood that the invention in its broadest aspect contemplates the setting of other kinds of fasteners, as, for instance, two different sizes or styles of eyelets, and where the term fastener is used in the claims, without further qualification, it is intended to refer to eyelets, lacing hooks, studs, rivets, or any similar devices which may be secured in the uppers of boots or shoes.

If desired, the several cam levers, which are normally maintained in operative relation to the pattern cams by the springs 248, may be provided with extensions 300, having connections 301, or the like, with treadles or other suitable operating devices, as shown in Fig. 3. By this means, the operator may lift any of the cam levers from their cams, and thereby render such cams ineffective to control the mechanisms connected therewith while the remaining cams operate to perform their usual functions.
