EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 603,023, dated April 26, 1898.

Application filed July 27, 1896. Serial No. 600,673. (No model.)

To whom it may concern:

Be it known that I, SEYMOUR FIELD, of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Eyeleting-Machines, of which the following is a specification.

This invention has relation to eyeleting-machines of the class typified by patent to F. W. Merrick, No. 427,340, granted May 6, 1890, in which patent is illustrated a machine provided with devices under the control of the operator for moving the punch and its bed away from the point where the eyelets are inserted to increase the space between the holes and means for arresting the feeding of the eyelets and causing the holes not supplied with eyelets to be made at a greater distance apart than usual for the reception of lacing studs or hooks.

The object of the presentinvention is to provide a machine of the type referred to with ad j ust-in g means for increasing or decreasing the distances or spaces between the holes for the eyelets and the greater distances or spaces for the studs; or, in other Words, the object is to provide means for varying the position of the punch relatively to the lower set when it operates to punch a hole and for varying the limits of the path of movement of the upper set, whereby the holes for the eyelets, as well as those for the studs, may be formed nearer or farther away from each other.

Another object of the invention is to provide the machine with means under the control of the operator for effecting the increase or decrease of the space between the holes without loosening any screws and by merely shifting a lever to one side or the other, to equip the machine with devices, also under the control of the operator, for withdrawing the raceway from the eyelet sets when holes are being punched for the studs or hooks, and to an to matically shift the adjusting devices after the wider-spaced holes for the studs have been made to cause the formation of the shorterspaced holes for the eyelets.

It is the object of the invention, likewise, toprovide a machine with additional improve ments whereby it will be rendered highly efficient in operation, easier of adjustment, and simpler in construction.

To these ends, therefore, the invention consists in a machine having those features of construction and arrangement which I shall now proceed to set forth in detail, and then point out in the claims which are appended hereto.

Reference is to be had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon, the same reference characters indicating the same or similar parts or features, as the case may be, wherever they occur.

Of the drawings, Figure 1 represents in side elevation an eyeletingmachine embodying my invention. Fig. 2 is an elevation from the other side of the machine. Fig. 3 is a plan View of the machine. Fig. 4 is a plan View of the top-set lever and the punch-bar, together with the mechanism for adjusting the throw of the same to change the spaces between fhe holes in the upper. Fig. 5 shows in detail and partially in section a portion of the adjusting mechanism. Fig. 6 is a section on the line 00a: of Fig. 3. Figs. '7 and 8 illustrate the cam-sleeve which is employed in adjusting some of the parts. Fig. 9 illustrates the eccentric-shaft and the parts mounted thereon for moving the raceway back from the eyelet-sets. Fig. 10 shows the connectionbetween the top-set lever and the yoke at the top of the movable bar hereinafter described in detail. Fig. 11 shows in detail the adj usting means for a portion of the machine, being a section on line 11 ll of Fig. 3.

In the drawings, n represents the supporting-frame of the machine, having a vertical bearing l), in which is journaled a stud 0, provided at its upper end with a head d, in which is pivoted at e the top-set lever f. To one end of the lever f is secured the top set g, the other end h of said lever projecting through a wide yoke i in the upper end of a vertically-movable bar 3', mounted in bearings at the end of the frame. The cross-aperture in the yoked is considerably Wider than the end it of the set-lever, so that the said lever may oscillate on the stud c relatively thereto.

is the powershaft, which is suitably j our naled in bearings l in the frame a, being provided on its end with a loose belt-pulley m, adapted to be connected therewith by a clutch n. On the shaft is rigidly secured a disk 0, having a cam-groove to receive a roller 1) on the end of the vertically-movable stud or bar j. lVhen the shaft It is rotated, the bar j will be reciprocated vertically, as will be well understood. The end h of the top-set lever is provided with a spherical knob q, and between said knob and the upper and lower walls of the yoke I place cups 1" or sliding pieces having concave faces to receive the knob q. The yoke is arranged at a. tangent to the path of oscillation of the lever f, so that when the lever is reciprocated the ball orknob (1 will move perfectly in its cup-like sockets or bearings r irrespective of the position of the set-lever relatively to the yoke.

On a bracket 8, extending out from a collar h on the stud c, I bolt the punch-block bar 25, which has at its front end a punch-block or abutment u. The bar tis stationary vertically and is provided at its rear end with upwardly-extending ears 2;, in which is pivoted the punch bar or lever 10, the bar t being also provided with guides as for the front end of said lever. The front end of the lever to is provided with a socket to receive the punch y, suitably held therein by a set-screw e. In the rear of the punch y the lever w is formed, with a through-aperture a to receive ablock b, having its end connected to the forked arms 0 of a reciprocating bar 61', the latter moving in a bearing e and being actuated by a disk f, having a cam-groove into which a roller g on the end of the bar d extends. The cam'grooved disk f is suitably secured to the driving-shaft by a pin or otherwise.

The top-set lever coacts with a verticallyreciprocated lower-set bar 2", which latter is guided in bearin gs j on the frame and is actuated by a cam 70. The lower set Z is suitably mounted in its bearings and held therein by a screw m.

I so connect the punch bar or lever and the top'set lever that they are moved in unison about the. stud a, providing devices whereby the distance to be traversed by them will be varied in accordance with the distance to be left between the holes formed by the punch, and also devices for adjusting the punch-bar lever and the top-set lever relatively to each other.

It is of course understood that in operation the punch-bar is actuated to punch a hole in the upper and is moved back out of the way to permit the top-set lever to be moved down to enter the hole cut by the punch and to move laterally, so as to feed the whole upper laterally until the top set is in line with the lower set, when they are actuated to set an eyelet in the hole. Hence when it is desired to leave a greater space between two holes in an upper the punch must form a hole at a greater distance from the lower set, and therefore the upper-set lever must traverse a greater distance in feeding the upper to the lower set, and it is also necessary that at the end of the movement of the upper set it should be exactly in alinement with the lower set, which latter is stationary, in order that they may coact properly in setting the eyelet. In addition to these devices I also provide a mechanism for limiting the path of oscillation of the top-set lever and the punch-bar and for varying it to suit the particular occasion, all as I shall now explain.

In a bearing m bolted to the side of the frame, I mount a vertical rock-shaft n, having on its lower end an arm 0', with a roller 1) lying in a cam-groove q in the disk 0, so that when the disk 0 is rotated the shaft 01 will be rocked or oscillated. The upper end of the shaft n is provided with an arm 2", extending at right angles to the arm 0 and connected by a link 8' with a slideway t, pivoted on the vertically-reciprocating rod 7'. The head at of the stud c is extended out in two bars 1), to form upwardly-extending ears or guides tU-for the top-set lever f, and below the bars is a slide 10, which has a portion 4r, extending down into the slot y in the slideway i. z is a small plate secured to the portion 00' of the slide and extending under the slideway, so as to hold the slide in place. Now it will be seen that when the rock-shaft n is rocked it will, through the arm 0" and the link .9, oscillate the slideway t, and through the medium of the slide w oscillate the topset lever f on the stud c. Arranged beneath the bars 1), extending out from the head (Z, is a plate a having a curved slot 19 which is eccentric to the stud c and at an angle to the top-set lever f, and extending down into said slot 12 is a pin 0 secured to the end of the punch-block bar t. The slide w is connected by a link (Z with alever e pivoted on the vertical shaftj. The plate a has a rectangular portion f extending up between the bars n, so as to slide therein, and is apertured at g to receive a pin 71. projecting up from the slide 10. Thus it will be seen that the abutment block-bar and the punch-lever are connected with the top-set lever, so as to move therewith. When the lever e is rocked around the shaftj to the left, (see Fig. 3,) it will, through the link 61 force the slide to away from the shaft j, carrying with it the plate (B, so that the walls of the slot 12 will force the pin 0 away from the top-set lever f, causing the abutment block-bar and the punch-lever to be swung around the stud c relatively to the top-set lever. This will increase the distance to be traversed by the top-set lever as well as that traversed by the punch-bar.

The path of oscillation of the slideway 25 being uniform, it will be readily seen that by moving the slide 10 away from the center of oscillation the slide will traverse a relatively greater distance and will therefore cause the top-set lever to be moved a greater distance, and by drawing the slide w toward the pivot of the slideway the said slide 20 will traverse a relatively shorter distance, and thereby cause the top-set lever to traversea shorter distance.

The lower set is stationary laterally, and the top set operates to feed the upper to the lower set after'the hole has been punched in, as has been described. Hence when a greater distance between the holes is desired it is necessary to punch a hole farther away from the lower set, and therefore the top-set lever must traverse a greater distance in feeding the upper along to the lower set, the punch bar or lever also traveling a relatively greater distance. If the top-set lever and the punchbar were made to travel a greater distance or move in a longer are without varying the positions of the same relatively to each other, it would follow that theupper set would not properly engage in the hole made by the punch, or, in other words, the rearward limit of movement of the top set would not be in alinement with the forward limit of movement of the punch; and hence, when it is necessary to efiect a longer throw of the top set, it is'also necessary to adjust the punch-bar relatively to the top set, so that, when the punching action takes place, it will be exactly the point at which the top set descends to engage the hole. This adj nstment of the punchbar relatively to the top-set lever is effected by the pin 0 traveling in the slot b in the plate (1. the slot beingat an angle to the set lever, so that when the slide and the plate a are moved forward to increase the arc of travel of the set-lever the punch-bar and the abutment-bar are swung slightly around the stud 0, so as to cause the punch-bar to make a hole in the upper in that line to which the top set and the lever f will be moved. The end of the path of movement of the top set in its forward direction is in alinement with the axes of the stud c and the shaft j, the.

cam slot (1 being so curved as to effect this, the lower set being in that line and being stationary. Hence when the lever c is thrust to the right in Fig. 3 it draws, through the medium of the link (2 the slide to and the plate a toward the shaft 3'. This movement causes the top set 9 to move slightly laterally or forward toward the lower set, and the pin 0 sliding in the slot b in the plate (0 will move the punch y nearer to the set g, as will be clearly seen. Thus the movement of the lever e automatically increases or diminishes the pat-h of movement of the set-lever and adjusts the punch-bar relatively to the said lever.

By referring to Fig. 5 it will be seen that I have provided lever e with a sliding dog f having its front end serrated to engage .the serrations g ona sector-shaped plate 712. The dog or latch f slides on suitable guides and is provided with a recess i having inclined end walls j Z is a thumb-lever pivoted on the under side of the hand-lever c and having its pivot 721 cut away to form asemicylindrical cam, which, when it is rocked,will have its periphery in engagement with the inclined walls 3' or M, respectively. \Vhen it is desired to slide back the latch f from the serrations 9 the thumb-lever Pis pressed toward the lever e and the camlike pivot m engages the end wall j of the recess and draws the latch back, so that the lever e can be moved to the right or to the left.

On the sector-plate h I place an adjustable gage to limit the movement of the lever c The gage is conventionally illustrated as consisting of two pins 0 19 adapted to be inserted in any of a series of holes g in the said sector-like plate. By means of these pins the amount of adjustment of the top-set bar and the punch may be limited. In order to adjust the setting and punching mechanism relatively to the cam g, I place in the aperture in the link 8 an eccentric sleeve .9 to receive the pivot-pin r which connects the link 8' with the arm r. By adjusting the position of the cam-sleeve the link 5 and the arm r may be adjusted relatively to each other.

, In addition to causing the formation of holes at a greater distance apart than those first made by the punch for the reception of the eyelets it is desired to prevent the eyelets from being fed to those first-mentioned holes,-since it is desired to place in them studs or hooks. Hence I shall now describe the raceway for the eyelets and the mechanism for preventing the eyelets from being fed to the said holes.

A o is the raceway through which the eyelets pass from the hopper 0 and the receptacle 03 The raceway and the hopper and receptacle may be of any approved pattern, since I do not limit myself to the employment of any particular kind. The support 3 for the raceway is pivoted at a to a'plate a the lat ter being itself pivoted upon a shaft 12 supported by the frame a of the machine and extending through to the other side of the same. The plate a" has an arm 0 extending downward and provided with an inwardlyprojecting roller lying in the cam-groove d in a cam-disk a f is a link pivoted to the support g for the raceway and pivoted to the frame C1,. hen the cam-disk c is revolved, the pin in the cam-groove d will cause the oscillation of the plate a about the shaft b and a consequent reciprocation of the raceway toward and from the set, as will be clearly seen. About the pivot'g for the linkf is placed an eccentric sleeve h which fits in the circular aperture in the link f By turning the sleeve, which is formed with a polygonal flangej for this purpose, the link f may be adjusted vertically, so as to raise set. enters into it and moves the work alonginto the path of the lower set, as has been stated. As the lower set ascends it engages an eyelet in the end of the raceway, which has been moved forward, and the two sets firmly bind or secure the eyelet in place; but when the holes are formed in the upper for the reception of the studs or hooks, which holes are at a greater distance apart than those formed for the eyelets, I provide. means for throwing the raceway back, so that when the lower set rises it will not engage an eyelet therein. The mechanism for accomplishing this is as follows: The shaft 6 upon which the plate a is mounted, is provided with a crank, on which said plate a is pivoted. The other end of the shaft is provided with a bellcrank lever having two arms Z and m The arm Z is connected with a treadle below the working bench (not shown) by a link if. Hence when it is desired to move the raceway back from the lower set the treadle is depressed, rocking the shaft b ,and consequently dropping the plate aand the support for the raceway o thus moving the end of the raceway out of the path of the lower set. At the same time I desire to automatically shift the lever 6 forward, so as to increase the path of motion of the upper set, and hence I connect the arm m of the bell-crank lever by a link 0 with an inwardly-extended arm p forming a part of the thumb-lever Z When the treadle is depressed, it draws upon the arm 19 to turn the pivot m and draw the latch back from engagement with the sector-plate, and finally swing the lever e forward until it engages the pin 0 After the holes for the studs have been formed in the upper pressure upon the t-readle is removed and a spring g draws the arm Z of the bell-crank lever upward, and a spring r interposed between the lever e and the sector-like plate h throws the lever e backward into its original position.
