EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 384,157, dated June 5, 1888.

Application filed October 17, 1887. Serial No. 252,577. (No model.)

To all whom it may concern:

Be it known that we, LORENZO D. HAW- KINS, of Stoneham, in the county of Middlesex, and JOHN G. PAIGE, of Boston, in the county of Suffolk, both in the State of Massachusetts, have invented certain new and useful Improvements in Eyeleting Machines, of which the following is a specification.

This invention has for its object to simplify the construction of eyeleting-machiues which punch and feed the work, and to generally improve the construction of such machines with respect to convenience and efficiency of operation and capability of change from one size or shape of eyelets to another.

To these ends our invention consists in the improvements which we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents aside elevation of ourimproved machine. Fig. 2 represents an end view of the same. Fig. 3 represents a section on line :0 m, Fig. 1. Fig. 4 represents a section on liney Fig. 2. Fig. 5 represents a section on line z 2, Fig. 1. Figs. 6 and 7 represent, respectively, sections on lines :0 x and y 3/, Fig. 1. Fig. 8 represents a section on line 2 a, Fig. 2. Fig. 9 represents a view of the opposite side of the driving pulley and clutch from that shown in Fig. 1. Figs. 10, 11, 12, 13, and 14 represent sectional views showing the punching and setting devices at different stages of the operation.

The same letters of reference indicate the same parts in all the figures.

In the drawings, or represents the frame of the machine,having the work-supporting table a and the arm or goose-neck a overhanging the table and separated therefrom by a workreceiving recess, 48, which extends into the frame from the work-table and is adapted to receive the article to be eyeleted and permit said article to project a considerable distance inwardly from the point where the eyelet-inserting devices act.

In the arm a is journaleda shaft, 1), having cams, the purposes of which will be presently explained. Said shaft is connected with the main driving-shaft c, which is jourualed in bearings in the lower part of the frame a by a vertical shaft, d, having bevel-gearsee, meshing with like gears, ff, on the shafts b c.

g represents aslide adapted to move between vertical guides h hon the outer end of the arm a, and having a stud, i, entering a cam-groove, j, in a disk, It, affixed to the shaft b, said cam groove and stud reciprocating the slideg vertically when the shaft 1) is rotated. The lower end of the slide 9 has a horizontal dovetail guide, Z, on which is fitted to slide horizontally a carrier, m. To said carrier is affixed by a set-screw, n, a punch, 0, which projects downwardly from the carrier and is formed at its lower end to punch a hole in the material to be eyeleted. The carrier and punch are reciprocated vertically by the slide g, and the carrier is moved horizontally while the punch is depressed, so as to cause the punch to feed the material, and is moved horizontally in the opposite direction while the punch is raised to bring the punch back into position to again descend and punch and feed the material. The carrier is reciprocated horizontallyon theguide Z by the devices next described.

To the back of the carrier is affixed a stud, p, which projects into a vertical slot, q, in a bar, 1', adapted to slide horizontally in guides s s, affixed to the arm a, said slot being vertically elongated, so that the stud can move vertically with the slide 9. To one end of the bar r is pivoted the lower end of a lever, 25, which is adapted to oscillate on a verticallyadjustable fulcrum-pin, a. The upper end ofthe rocking lever t is pivoted to a link or arm, 1), which has a stud entering a cam-groove, w, ina disk, :12, on the shaft b. Said stud and arm are supported by a link, y, pivoted at its lower end to the link i) and at its upper end' to the arm a. The rotation of the disk 00 causes the can1 groove w to oscillate the rocking lever t, and the latter, by its connection with the bar a", re ciprocates the latter, and with it the punchcarrier m. The fulcrum-pin u is mounted in a slide, of, which is vertically adjustable on aslotted ear, b, affixed to the arm a. The fulcrum-pin has a shoulder bearing against one side of the slotted ear b and a reduced threaded end which passes through the vertical slot 1) in said ear, and has a clamping-nut, c, which secures the fulcrum-pin to the ear I) at any height within the range of its adjustment in the slot 1). The lever t has a longitudinal slot, d, which permits the described adjust ment of the fulcrum-pin. The vertical adjustability of the fulcrum-pin enables the throw or horizontal movement of the punch to be varied so as to make the distance between the eyelets greater or less. By raising the fulcrum-pin the throw or feed movement of the punch is increased, while by lowering said pin the throw of the punch'is decreased. 6 represents a block containing a female die, which co-operates with the punch in making the holes. Said die-block is attached to a slide or carrier,f, adapted to move vertically in fixed guides g g on the frame a, so that the die-block can be raised to co-operate with the punch and then descend to clear the punch and permit the latter to feed the work while inserted therein.

The die-carrier is reciprocated vertically by means of a bar, It, adapted to move vertically in guides z" 12 on the frame a, and provided with an arm,j, which has a stud entering a cam-groove in a disk, l, on the shaft 0, and another arm, is, which enters an orifice formed for it in the die-carrierf. The rotation of the disk I causes the cam-groovetherein to reciprocate the bar h vertically, and said bar by the arm 75 reciprocates the die-carrier, the parts being so timed that the die is raised just before the punch descends and lowered just after the hole-is formed in the material.

The die-block is detachably secured to the carrier f by a clamping-plate, m, secured by a screw to the carrier and bearing against one edge of the die'block. By loosening said plate the die-block can be removed to be replaced by by another of different form or size in case a like change is made in the punch; or the die-block may have a series of dies, either of which may be brought into operative position by an adjustment of the die-block, which is permitted by the clamping-plate. The punch on its return movement must of course be brought into exact alignment with the female die, a stop, at, being employed to secure this result. We make this stop adjustable, so that wear of the stop or of the end of the carrier, which abuts against it, as well as lost motion of the devices which move the punch-carrier horizontally, may be compensated for. To this end the stop a is engaged with a screw-threaded rod, 0, which is jonrnaled in the lower end of the slide 9, so that when rotated it will not move endwise, the stop at having a tapped orifice, through which said screw passes, so that when the screw is rotated it will feed the stop along it, as will be readily understood. Ajam-nut, p, on said rod, when turned to bear on the edge of the slide 9, prevents the an enlargement or shoulder, q, constituting the top set, against which the end of the tube of the eyelet is upset, as hereinafter explained.

r represents the bottom set, which is attached to a vertically-reciprocating bar or carrier, 8', adapted to move in guides t t on the frame a, and provided with a horizontal grooved cross-head, which receives an eccentric stud or pin on a disk, to, on the driving shaft, these devices reciprocating the bottom set vertically, as in other well-known eyeleting-maehines. The bottom set is formed to support the flange of an eyelet and is provided with the usual spring-supported spindle, 22, which, when the bottom set is raised, enters the lowermost eyelet in the chute or roadway w and holds said eyelet on the bottom set until it is engaged with the material. 20 represents the chute or roadway which conducts the eyelets from the reservoir w.

The roadway and reservoir are rigidly connected and the roadway is formed, as usual in machines of this class, to guide the eyelets with their flanged ends downward to a point 7 over the spindle '0, so that when the latter rises with the bottom set it will enter the lower eyelet, the reservoir being provided with an oscillating brush or agitator, which forces the eyelets out through ports in the side of the reservoir into the raceway.

The form of the raceway and reservoir and the brush or agitator are not parts of the present invention, and are not therefore particularly described.

We have improved the means for connecting the reservoir and roadway to the machine, so that said parts can be easily and quickly detached from the machine and another reservoir and roadway formed to guide differently shaped or sized eyelets can be applied. To this end we secure to the frame a a bracket, 2, having an obtuse-angled sleeve, 3, at the upper end of which is an inclined seat or flange, 4, on which the reservoir rests. In said sleeve are journaled two short shafts, 5 6, which are provided with intermeshing teeth 7 7 on their adjacent ends, said teeth being so formed that the upper shaft, 6, which is oblique to the lower shaft, 5, is oscillated by the latter, which in turn is oscillated by an eccentric, 8, on the vertical shaft 01, and a rod, 9, connecting said eccentric to an eccentric wrist-pin, 10, on the lower end of the shaft 5.

The oblique shaft 6 has a square socket in its upper end, which receives the squared end of the shank or arbor 12, to which the brush or agitator within the reservoir is affixed. The oscillating motion imparted to the shaft 5 by the rotation of the eccentric therefore is communicated through the socketed shaft 6 to the brush or agitator. The lower portion of The bottom of the reservoir has a IIO circular tubular stud, 16, which projects into the upper end of the fixed sleeve 3 and serves as the center on which the reservoir and roadway oscillate. The shank 12 of the brush or agitator passes through said tubular stud.

The lever 15 is attached to or formed on a rock-shaft, 17, which is journaled in a; fixed bearing, 18, and has an arm, 19, which bears on a cam, 20, on the driving-shaft c. A spring, 21, secured at one end to the frame a and at the other end to the lever 15, keeps the arm 19 in contact with the cam 20, and the said spring and cam conjointly give the roadway its oscillating movements.

The reservoir and roadway are not positively secured to the parts that support them, but may, without any unfastening, be lifted from the sockets in the fixed sleeve 3 and in the lever 15, they being held in said sockets by gravitation only. It will be seen, therefore, that the reservoir and roadway may be very easily separated from the machine and replaced by another reservoir and roadway fitted to hold differently formed or sized eyelets. It will also be remembered that the punch 0 and die-block e are readily detachable, so that the machine can very quickly be altered, so that it will set eyelets of a different size or shape.

The time of the movements of the punching and setting devices is as follows: The punch being raised and in position over the female die, as shown in Fig. 10, is depressed and cooperates with the female die in cutting a hole in the material, as shown in Fig. 11. The dieblock then descends from the punch, as shown in Fig. 12, and the latter moves laterally, feeding the material until the punch is inline with the bottom set, as shown in Fig. 13. The bottom set then rises. At this time thelower end of the roadway is over the bottom set, so that the spindle v in rising enters the lower eyelet. As soon as the spindle has entered the eyelet the roadway is moved back, leaving the eyelet on the spindle, its flange resting on the bottom set. The bottom set continues its upward motion, the finger striking the lower end of the punch and being arrested by it, while the bottom set continues its upward motion,inclosing the punch and inserting the tube of the eyelet through the material around the punch, and finally upsetting the upper end of the tube of the eyelet against the top set. It will be seen that the top set and punch are formed and operated together, the top set being a shoulder on the shank of the punch. We thus materially simplify the construction of the machine by dispensing with an independent top set and operating devices therefor. The presser-foot 22 is raised before the feeding of the work by an arm, 23, hearing against a collar, 24, on the presser-bar 25, a rock-shaft, 26, journaled in bearings on-the arm a and having an arm, 27, and a cam, 28, on the shaft 1), the arm 27 having a roll which bears on said cam. The rock-shaft is also provided with an arm, 29, which may be connected by a rod with a suitable foot-lever.whereby the operator may raise the presser-foot when he desires to insert or remove the work.

The spring 21 enables the roadway to be pushed or held back from its delivering position, so that the eyelets may be omitted whenever desired. To enable the operator to thus hold back the roadway,we provide a bell-crank lever, 30, which is pivoted at 31 to the frame a, a slide, 32, pivoted to one arm of said lever and bearing against the roadway'supporting lever 15, and a connecting-rod, 33, connecting the bell-crank lever 30 with a foot-lever. The operator by depressing said foot-lever can force the slide 32 against the lever 15, and thus displace the roadway.

The shaft 0 is provided with a loose pulley, 34, adapted to slide on the shaft and having a clutch, 35, on its hub adapted to engage a clutch, 36, affixed to the shaft. Said pulley is engaged with a bar, 37 which is adapted to move in fixed guides 38 38 and is provided with a sliding pin, 39, which is pressed upwardly by a spring, 40, and is connected by a rod, 41, with a foot-lever below the machine. On the clutch 36 is formed a cam shaped flange, 42, oneside of which is inclined. When said pin is released by the operator, it springs upwardly, so that it bears against the inclined side of the flange 42, and is forced outwardly thereby with the bar 37 and the pulley 34, which is engaged with said bar by a fork, 43, on thclatter enteringa groove in the hub of the pulley. This movement separates the pulley from the clutch 36 and at the same time causes a wedge, 44. secured to the bar 37, to raise a brake-shoe, 45, resting on it, and to press said shoe against the periphery of the disk Z, thus instantly stopping the operation of the machine. When the operator depresses the pin 39 and disengages it from the flange 42, aspring, 46, on the bar 37 moves said bar so as to engage the pulley 34 with the clutch 36 and at the same time move the wedge from under the brake-shoe 45, thus starting the machine.

When the machine is used in eyeleting c0r sets or other articles made of cloth, we prefer to employ a punch with a conical pointed end, as shown in Fig. 4. To prevent the point of the punch from being injured by the eyelet-engaging spindle,we make a cavity, 47, in the upper end of the latter, as shown in Fig. 13.

In some cases it is preferable to form a V- shaped groove in the end of the punch, and with a punch so formed we usea pointed spindle formed to bear only against the apex of the groove of the punch, as shown in Fig. 14, and avoid dulling the cutting-edges thereof.
