ing the work to operate upon it and in moving away from it, the mechanism also allowing the lateral movement of: these devices necessary for feeding the Work, and having convenient provision for adjusting the -pressure ofthe punches and sets upon their,respectiveicutgng blocks and upsetting dies. 1

A further feature of t-he present invention relates to the construction and arrange ment. 'rof the raceway which, iii-accordance \l'ltl'l -ll'ly invention, may he made stationary and extendedto a point in the'rear of the settingposition where it is provided with-a delivery opening from which the setting dies extract the eyelets prior t'oeaelrsetting operation.

These and other featuresof theinvention will be best understood and appreciated from the following description of: iny'infven} tion as embodied in an eycletmg machine lot the type j referred to and shown in the accompanying drawings in which,--

Figure'I is a side elevation; Fig. 2 is a partlal'plan View, the raceways being 1'6" 'moved; Fig. 31s a plan view of the anvil plate and work guiding means; Fig. 4 is a fragmentary view in perspective with the partsas arranged for the punching opera? tion. 1* i y f i The present machine, like the machine of said patent, is organized and arranged to punch two holes in the opposite sides oftlie upper of a shoe and then to set two eyelets in these holes and to feed the work.

Before n'oeeetling to a detailed description of the various parts of the machine it will be convenient to refer to the principal operative parts and their general mode of.

operation and relatiije arrangement and then to proceed, witlradetailed description of their operating mechanisms and their com'iections therewith.

The machine illustrated in the drawings has a frame 2 which is provided with hearings for the main shaft 4 adapted to be connected at one end with apulley which re-' ceives a. belt by which the machine may be driven from any convenient source of power and provided upon its other end with a hand wheel 6. The frame is provided with a base 8 which is adapted to be secured to a bench.

The present machine is arranged to operate upon work presented thereto at an inclination of about 45 which has been found to be the most convenient position of the work for the operator. oppositely disposed punches and oppositely disposed setting dies or sets 12 are arranged in bearingsin a support or feed frame l fwith the anvil or die plate 16 also supported by said feed frame and arranged between the oppositely disposed punches and sets.

The yielding presser feet 18 are arranged upon opposite sides of the guide plate 20 and act to hold the two quarters of a shoe in contact with the guide plate. In presenting work to the machine, the presser foet are displaced from the guide plate by the work and the opposite sides of the upper are laid against the opposite sides of the guide plate with their edges against the edge guide mounted upon said guide plate. The machine is set in operation by tripping a clutch which may be of any suitable type, preferably such a clutch as that disclosed in the patent above mentioned. The punches thereupon are actuated to punch holes in the opposite sides of the upper in alinement with each other and then the feed frame 14 is moved forwardly and downwardly to bring the sets into the position previously occupied by the punches. The sets are pro: vided with center spindles 13 which are projected into the lowermost eyelets in the raceways 15 during the punching operation and which extract the eyelets to be set from the raceway upon the forward movement of the feed frame. When the setshave earriedthe eyelets into alinement with the previously punched holes they are actuated for clenching the eyelets in cooperation with the upsetting dies mounted in the anvil plate 16. After the eyelets have been set, the sets are released slightly but still held in engage-- ment with the eyelets and then the feed frame 14 is moved transversely to feed the work the desired distance between two successive eyelet holes. The setting dies then disengage the work and finally the feed frame is moved rearwardly and transversely in the opposite direction, bringing the punches back to their original positions and the operations may then be repeated. hen holes in the upper for exampl e, the raceways may be-moved manually to an inoperative position so as to prevent them from delivering eyelets to the sets, the only difi'erencein the operation of the machine being that the sets operate merely to feed the'upper without setting eyelets therein.

Having briefly outlined the general construction and operation of the present mach ine, its mechanical features-and construc tion w ll now be more specifically described.

The guide plate 20 against the opposite sides of'which the work is adapted to be held and across which the work is drawn as it is moved to the setting position, is normally stationary but may be shifted transversely to the line of feed and in such movement carries the edge gages 22 by the shifting of which relative to the setting devices the spread of the eyelets may;v be varied. The guide plate is normally frictionally maintained in'its forward and lowest position corresponding to the minimum spread required in the eyelets. The guide plate and edge gages may be shifted rearwardly for increasing the spread of the eyelets by swinging the lever 30 acting through the link 24 which is connected to a segmental gear 25 meshing with a rack 26 formed on the shank of the guide plate 20, as shown in Fig. 3. In order to. decrease the spread of the eyelets, the link 24 may be actuated automatically from the main shaft by the lever 27 carrying the pawl 28 which is adapted to engage a notch in the link 24 as explained at length in Patent No. 934,066 above men-' tioned. By means of the arrangement above described the operator may set the edge gages for a wide spread before starting to eyelet each shoe and, through the lever 27, the gages are automatically shif ed to a position for less spread after the first two or lower eyelets have been set. In this way it is possible conveniently tov set the lowest eyelets with a wide spread and the remaining eyelets uniformly with a lesser spread.

The presser feet 18 comprise' yielding presser members attached to the leaf springs 19 which are mounted on the edge gages 22 and which serve to hold the presser members :yieldingly against the faces of the guide plate 2-0 or the work thereon. The presser members engage the work at all times, both 'during and between the feeding movements, and serve ,to position it correctly and smoothly upon the guide plate. They also act with, the guide plate, when the latter is shifted for varying the spread of the eyelets, to carry the work bodily forwardly or rearwardly relative to the punching and setting devices.

The feed frame 14 constitutes a support for the punches, eylet sets, anvil and associate parts. .The feed frame carries upon its rear enda j ournalspindle 44, the extended ends of which are received in hearings in the forked bell crank lever 45 pivoted at 46 on a bracket extending from one side of the U-shaped frame 49 which in turnis bolted to the main frame 2 ofthe machine. The rearwardly extended arm of thebell crank lever 45 carries a cam roll which engages in a cam track 48 formed in a cam drum 43 on the main shaft 4. The above described arrangement is such that after.

the holes have been punched in the work by arraiigerne, l a aresuch'that afterthe feed framehas been:

ating lever 73 and as in that case its downwardly extending arm is provided with gear teeth which mesh with corresponding teeth formed on the end of the upwardly extending arm of the lower set actuating lover. The lower actuating lever has an articulated rearwardly extending arm 86 carrying the cam roller 87 which is actuated by a'cam 8S rigidly mounted on the main shaft of the machine. The arm 86 is pivotally connected with the lower actuating lever 83 and a stiff compression spring is interposed between a lug on the arm 86 and the lever 83 which may allow a yielding movement between the parts of the lever in case the dies encounter an obstruction. The cam 88 is so designed as to actuate the setting dies toward the die plate to a limited extent simultaneously with the punching movement of the punches. This movement is sufiicient in extent to allow the center spindles 13 of the setting dies to impale the lower eyelet in each raceway. The setting dies are maintained in this position during the forward movement of the feed frame and extract the impaled eyelets from the raceways and carry them into alinement with the previously punched holes. The setting dies are then further actuated to cleneh the. eyelets in coiiperat ion with the upsetting dies (30 mounted in the anvil plate and are then slightly retracted in order to relieve the pressure on the elements of the machine but not enough to release the clenched eyelets, and the sets remain in this position during the transverse feeding movements of the frame 14.

In order to remove the punches or setting dies from the, feed frame for replacement, the pivot pin 54 may be removed and the link 51 disconnected from the cam lever 52. The feed frame 14 may then ;be moved to the left an amount sufficient .to carry the punch s and sets off the ends of the spindles 70 and 80 so permitting the punches and sets to be withdrawn by hand.

h'lcchanism for regulating the extent of the feeding motion transmitted .to the feed frame may be provided "of substantially sin'iilar type to that disclosedin the above mentioned patent. At the pivotal point of the links and 51 is secured 'a link 92 whichispivoted at 93 upon the arm 94 arranged, for movement over the face of the quadrant plate95, stop pins 96 being providedto limit its movement. The arm 94 is mounted upon a shaft '97 (see Fig. 1) which is supported in bearings on the frame of the machine and carries upon its lower end an arm 98 which is connected by means of a chain 99 witha treadle, not shown. By de pressing the treadle, the arm 94 is swung over the surface of the quadrant plate to increase the distance between successive eyelots amTas shown in Fig. .Zt-he'arm 94 is held I wheel 118 is formed an upwardly project over in position for wide spacing. This arrangement is of great convenience when it is desired to punch-holes for lacing hooks with a greater spacing than for the eyelets already set, the spacing being increased and the raceways simultaneously moved to inoperative position. The arm 94 is returned to its original position, that is to say, the position for minimum spacing,'by means of the spring 100.

The means for delivering eyelets to the eyeletsetting devices, comprises the hopper 110 and the raceways 15 which convey eyelets from the hopper to the setting-devices. The hopper may comprise a cylindrical casing ha. ng its bottom arranged at an inclination to the horizontal and may be provided with the usgal outlet ports for the eyelets and with an agitating device such as a brush which serves to sweep the eyelets out through the ports to the raceways. The brush is secured to a short shaft 111 extending through the bottom of the hopper and having mounted on its lower end a disk carrying a projecting lug 112.

A bracket 113 is pivotally mounted by a pin 114 on the frame of the machine and carries two upwardly extending lugs which are provided with clamping screws 115 for engaging downwardly extending lugs on the raceway frame 116.. The bracket 113 is provided with bearings for a 'worm'shaft 117 upon which is mounted a worm meshing with a worm wheel 118 journaled on a short pin projecting upwardly from the bracket. Upon the upper face of the worm ing lug 120 into the pathway of which ex- 1 tends the lug 112 fast to the brush shaft. At l its other end the shaft 117 is provided with apulley 122 which is driven by a belt runmug in a'groove formed in the eriphery/ of the cam 88 mounted on the sha t 4, The/ above described arrangement is such that the agitating brush is driven from th'e'main shaft of the machine whenever the machine is set in operation. The bracket is normally maintained in such position that the en ds of the raceway are in alinement with the setting dies by the compressionspring .124 5 encircling" the spindle 126 which is pivoted to the frame of the machine and project's ,through the pivoted abutment 128 011' the bracket. The normal position of the bracket is determined by the sleevel30whichis ea justably mounted on the end of the /spindle- 126 and provided with a locknutf 'or holding it in any adjusted position. Bymeans y t of this construction the raceway may be swung outwardly by hand into/an inoper ative position when it is, desired to punch holes in the work for lacing'h'obks.

The pulley 122' andthe corresponding pulley on the main shaft are grooved deeply for the reception of the roun belt in horde! 7 that the belt shall not run, off the pulley when the bracket is swung by moving the raceway into inoperative position.

It is important in the operation of eyeleting machines that the 'niac'hine should always come to'rest when the power is disconnected with the parts in such position thatthe' work "may be removed a-ndnew Work entered therein and to this end various clutch mechanisms may be employed. A suitable clutch mechanismv is described. length. in, the patent above n'ien'tio-ned, to which further reference may be had for its detailed construction, or reference maybe had to the co-pendingapplication-ofA. F. Littletield No. 341,738 filed November .2, 1906, which covers an improvementon the clutch disclosed in said patent.
