EYELETING-MACHINE.

Specification o Letters Patent.

Patented Jan. 5, 1909.

Continuation of application filed April 22, 1902, Serial No. 104,109. This application filed July 11, 1903. Serial No. 165,084.

To all whom it may concern:

Be it known that I, `GEORGE KNIGHT, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented an Improvement in Eyeleting-Machines, of which the following description, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel eyeleting machine.

My invention is illustrated in a machine for setting a plurality of eyelets of each cycle of o eration of the machine.

I eretofore a plunger contained in one of the pair of sets has been used to pick off from a raceway an eyelet to be set, and punched stock having been put on the plunger, the set has been moved to set the eyelet. So, also, an eyelet has been put by hand upon a plunger, and the plunger holding the eyelet has been moved to co-act with a hollow punch to punch a hole through the stock, and the sets have thereafter been operated to insert an eyelet in the unched hole, and upset the eyelet in said ho e.

In seeking to improve the eiliciency of eyeleting machines, I have devised a machine comprising a series of top and bottom sets, a plunger, and a punch, said plunger and punch normally occupying a position in the same vertical plane. The plunger is actuated to enter the eyelet at the end of a raceway, and take the eyelet therefrom, after Vwhich the plunger holding the eyelet rises toward the punch and upper set. l The plunger holding the eyelet is so shaped .as to coact with an edge of the punch, and

out a hole in the stock, and thereafter as the sets are actuated they force the eyelets from the plungers into the stock, delivering the eyelets about the unch, and thereafter the sets acting in usualpmanner set the eyelets in the stock.

The end of the plunger is shaped to present a rounded projection rising from a shoulder, said projection as theplunger rises entering unerringly the endmost eyelet of the plurality of rows of eyelets at the delivery end of the raceway, after which the raceway is moved leaving the eyelets surrounding the plunger, the heads of the eyelets resting against the u per end of the lower or hollow sets. After the rounded ends of the plungers enter the eyelet, as stated, the plungers are further moved causing said rounded projections to enter the holes in the punches thus centering the plungers with relation to the punches, the movement of the plungers being continued until the shoulders of the plungers at the base of the rounded projections co-acting with the cutting edges of the punches cut holes in the stock to be entered by the eyelet. The diameter of the shouldersat the base of said projections is substantially as large as the external diameter of the punch, the plun er consequently acting as a guide for the eye et as it is being forced therefrom by the lower set to surround the punch prior to and during the process of upsetting the eyelet in the stock.

In the machine in which I have represented my invention to set a plurality of eyelets at one and the same cycle of operation, the plungers and lower sets are moved in different times to perform the results required of them.

The invention to be herein described and claimed is not, however, limited to the eXact shape shown for the said rounded extremity or the projection that enters and picks 0H the eyelet from the raceway, as the same may be varied to effect the result herein aimed at and yet not depart from my invention that I intend to claim broadly.

Figure 1 of the drawing represents in front elevation, partially broken out, a sufficient portion of an eyeleting machine to enable my invention to be understood; Fig. 2 is a side elevation of the parts shown in full lines in Fig. 1 looking toward the left of the drawing; Fig. 3 is a detail broken out to illustrate the plurality of under sets and plungers; Fig. 4 is a sectional detail showing the plunger coacting with the punch tube to unch a hole in the stock for the eyelet; i`ig. 5 is a section in the line rc', Fig. 3; Fig. 6 is a top view detached of the guide used to position the portion of the shoe to receive the eyelet; Fig. 7 is an inner side view of the parts shown in Fig. 6, and Fig. 8 is a section in the dotted line m2, Fig. 7.

The framework shown consists essentially of a base A having rising therefrom suitable standards A having bearings for the main shaft A2. This shaft is surrounded by a friction clutch pulley A3, of any usual construction and under the control of a device A that may be actuated by a treadle to start or stop the shaft.

The main shaft A2 has fast on it as herein shown two like eccentrics A5, and an eccentric A6, and said shaft has also a cam A7. Y

The cam A7 acts through a suitable lever B having its fulcrum at B to reciprocate the raceway B2 carrying the eyelets, the upper end of said raceway being movable in a suitable hopper B3 in which the eyelets are put in bulk.

The raceway is and may be oi' usual construction, and as shown it is adapted to contain a series of grooves to deliver a series of eyelets, a suitable spring 2 at the lower end of the several compartments of the raceway coacting with each row of eyelets to maintain them on the raceway until taken therefrom positively.

The eyelets contained in the hopper are kept agitated by any usual agitator carried by a shaft B4.

The framework has rising from it a suitable stand C having a stud C that serves as a fulcrum for two like levers C2, actuated by straps embracing the eccentrics A5, and an intermediate lever C3 that is actuated by a link embracing the eccentric A6. The framework has an overhanging neck C4 suitably recessed to receive a block D held therein by a suitable locking device D shown as an eccentric pin.

The block D has secured in it by suitable set screws D2 a series of up er sets D3, and a series of punches D4, eac upper set and punch having aV central passage as a, the upper end of which terminates at a in a discharge opening for pieces of leather punched from the stock in forming eyelet holes, said punchings entering a space a2 in a box a3 connected by suitable screws a4, one of which is shown in Fig. 2 with the overhanging part C4 of the framework.

Viewing Fig. 4 it will be seen that the shoulder a5 of the upper set D3 acts against the reduced end or point of the eyelet, and that the lower circular edge of the punch D1L extends sufficiently far from the shoulder a5 of the upper set to receive and sustain each eyelet as it is being u set.

The sharp edge of t e punch, shown as integral with the upper set, coacts with the shoulder or seat Z2 located at the base of the rounded projection or extremity b of the plunger bx, said extremity being shaped to enter unerringly, as will be described, the large or flanged end of an eyelet held at the lower end of the raceway, the eyelet surrounding the plunger thus enabling the latter to always remove the eyelet from the raceway as the raceway is retracted. In its further movement the rounded extremity ci the plunger enters and substantially iills the hole in the punch D4 and centers the plunger with relation to the punch. As the raceway is moved backwardly in usual manner the eyelets drop therefrom and surround the plunger, and the head ends of the eyelets are arrested while the head enters the upper ends of the lower sets b2. AS the rounded projection enters the hole in the punch the shoulders ofthe plungers meet the circular cutting edges of the punches and co-acting therewith cut clean holes in the stock for the reception of the eyelets.

Each plunger bx is extended through a hole in one of a series of under sets b2, the shanks of which are attached by suitable set screws b5 in a bar b3, said bar being connected with a sliding cross head b4 by means of a suitable set screw 5G.

The lower ends of the plungers bx are shown as having heads c that normally rest against a cross bar c extended through a space c2 in the cross head b4. The cross bar has suitably secured to it as by rivets c3 posts c4, shown best in Fig. 3, that are extended through suitable holes, see Fig. i, in the projection or boss c5 extended from the framework A. The boss is slotted vertically to receive the cross head b4, and a suitable cover plate as d held in place by screws d maintains said cross head b4 in its operative position.

The lower ends of the posts c4 are slotted, and in said slots are pivoted the upper ends of links d2 in turn jointed with the outer ends of the two like levers C2 actuated by said eccentrics A5.

The cross head b4 has at its lower end, see

' Fig. 3, two ears provided with holes for the reception of a stud g, see dotted lines Fig. 1, that serves as a pivotal connection for a link g', in turn connected with a pin g2 loose in suitable holes in the outer end ci' the lever C3 actuated by the eccentric A of the shaft A2.

The upper portion of' the boss c5 extended from the framework, supports a plate c that partially covers the lower sets and plungers,

said plate being pivoted at one end by a stud screw c2 entering a hole e in an ear of said plate, the ear at the opposite end of said plate having an open slot e3 that is entered by a clamp screw e4. The plate e has applied to its inner side, see Fig. 7, by screws f narrow plates f to constitute, with the part eX of the plate e, guideways for the feet f2 of gages f 3, f 4, said feet, as herein represented, overlapping one the other, see Figs. 7 and 8, and each foot has an inclined slot 12, said slots being directed oppositely. The narrow plates f have attached to them by screws 18 a slotted plate f5 having a series of teeth or projections 16 that may be engaged by the edge of a block 17 having extended from it a threaded post 18. Said post, after passing through one of the diagonal slots 12 in each of the feetf2 and through a vertical slot 19, see Fig. 1, in the part eX of the plate e, has

applied to it preferably a washer 20, a spring 21 and a nut 20X, the nut acting through the spring to hold the post and block 17 yieldingly. By pressing the nut 20X inwardly the post may be slid in the slot 19 and the slots 12 to thereby move the gages f3 and f4 away from or toward each other preparatory to the setting of a series of eyelets.

To locate the work for setting the eyelets l take hold of the work and place the linger cooperating with the thumb holding the work against the outside of one or the other of said gages, according to which part of the work, as the right or left hand portion of the top of a shoe, is being provided with eyelets. The work will also be grasped between the thumb and linger of the other hand, sirable because usually the worlr is pliable, and by engaging the same between both hands it is possible to securely hold the work taut under the sets and with the edge of the work in proper position with relation to the gages or stops as 22 or 23, according to the requirements of the work, each gage having a plurality of such stops.

1f the eyelets are to be equidistant from the edge of the material, the said edge may rest against either the two faces 22 or the two faces 23, according to the distance it is desired to set the eyelets from the edge of the material. 1f, however, it is desired to set the bottom eyelet at one edge farther from the edge of the material than the top eyelet at that edge, then l may put the edge of the material against the face 22 of the gage f i and a portion of the edge of the material at a distance therefrom against the face 23 of the gage f3.

The gages f 3 and f 4 sustain the material in position to be punched and to receive the eyelets in the punched holes.

Each upper set is acted upon by a strong s ring 7L under the control of a screw h. l ashers h2 are interposed between the ends of the set screws D2 and the bodies of the top sets, and in case of strain exerted on said upper sets or their connected punches, greater thaln they can or should bear, the springs will yie d.

In operation let it be assumed that the raceway has been supplied with eyelets, that the lowermost eyelet 1n each raceway groove is held by a spring 2X, that the material to be provided with eyelets is in position with its edge against one or the other face of the gages f3, f, and that the upper and lower sets are in the position Figs. l and 2. The machine will now be started, and immediately the eccentrics A5 will cause the cross bar c to act and project the plungers to their fullest extent from the lower sets that said plungers may enter the row of endmost eyeets of the raceway, and the lever B is then actuated to withdraw the raceway and leave an eyelet surrounding each plunger.

this being de- The punches D4 occupy at all times posi:- tions in line with the path of movement of the plungers, and as-the plungers bx and sets 7a2 continue to rise, the up er end ofthe plunger surrounded by an eye et meets the underside of the stocl, forcing the same against the lower hollow ends of the punches D4, and said plungers coacting with said punches punch a series of holes in the stock. During this o eration the ends of the plungers enter slight y the open ends of the punches, and the shouldered portions of the plungers meet substantially the circular cutting edges ofthe punches. 4 Viewing Fig. 4 it is supposed that the series of holes have been punched in the stock, and it will be seen that an eyelet surrounds the plunger below said end, and that the plunger is in position to act as a guide for the eyelet as the end of the eyelet passes from the plunger into the material and about the outer side of the punch. As soon as the plungers that are moved positively by the cross bar c, instead of being sustained by springs as usual, have coacted with the punches to punch a series of holes in the material, the upward movement of the plungers is sto aped, as in Figs. 3 and 4, but the crosshead L* continues to rise, causing the under sets sustaining the heads of the eyelets to act and force the eyelets into the holes made in the material, forcing the small ends of said eyelets against the shoulders a5 of the upper sets, thus clenching the eyelets in the material, and the eyelets having been set, the lower sets and plungers are lowered into their normal positions.

l have shown my invention applied to a gang eyeleter, but it is obvious that my nvention might be practiced to advantage in an eyeleting machine having but one bottom and top set, a plunger, a punch and a raceway,

l believe that 1 am the iirst to provide a machine of this class with independent gages having each an edge guiding face by which the edge of the material may be set in or out of line with a line intersecting all the punches to thereby provide for inclining the line of eyelets with relation to the edge of the material, or in other words, spreading the lowermost eyelets of the two series.

This invention is not limited to the exact shape shown for the end of the plunger, nor to the exact means illustrated for controlling the position of the gages.

lt will be noticed that the punches D4 eX- tend for a considerable distance beyond the shoulder a5 of the set D3, that acts against the small end of the eyelet. Elongating the punch as shown enables the eyelet being set to surround the punch and be guided thereby during the operation of setting the eyelets. This is necessary especially when a plurality of eyelets are being set at one operation, as the long punches act as positive guides in preventing any undue movement of the worn while the eyelets are being upset therein.

Pointing or rounding the extremity of the plunger greatly facilitates and insures the unerring entrance ofthe plunger into the eyelet at the end of the raceway.

This application is a continuance of my application Serial No. 104,109, filed April 22, 1902.

Having described my invention, what I claim and desire to secure by Letters Patent is l. In an eyeleting machine, a top-set comprising a bar presenting at its end apunch constituted as a hollow tube with a cutting edge, said bar having a shoulder at a distance from the cutting edge to permit the eyelet being set to be moved on to and to surround the punch, combined with an underset comprisingr a hollow bar, the upper end of which is adapted to sustain the enlarged end of the eyelet to be set, and a spindle movable inside said bar, said spindle having near its upper end a horizontal shoulder from which rises a protuberance having an upwardly rounded point to readily enter the eyelet, the

horizontal portion of said shoulder coacting with the circular edge of the punch to cut a hole in the stock, the upwardly rounded point of the spindle above said shoulder entering said eye et and hollow tube of the punch in advance of the cutting action of the unch, whereby said spindle is centered Wit relation to said punch.

2. In an eyeleting machine, means to present a series of eyelets, means to punch a series of holes in material, means to set a series of eyelets in said holes, gages to sustain the material to be punched preparatory to receiving eyelets, said gages presenting a plurality of faces to rovide for setting the eyelets at one end o' the series at a greater distance from the edge of the material than the eyelets at the other end of the series, and means to move said gages toward and from each other to adapt the gages to the work to be done.

ln testimony whereof, l have signed my name to this specification, in the presence ol two subscribing witnesses.
