JOHN E. WIGGIN, OF STONEAM., MASSACHUSETTS.
, Letters Patent No. 83,014, lla-tell October 13, 1868.; antedated September 26. 1868.
- The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Beit known that l, JOHN E. Wreenr, of Stoneham, in the county of Middlesex, and State of Massachusetts, have invented an Improved AutomaticPunching- Machine; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention suificient to enable -those skilled in the art to practise it. 4
This machine is designed for punching, in the maf tcrial of boots, shoes, Src., the holes intended for the insertion of eyelets, and is shown in side elevation in Figure 1, in sectional plan in Figure 2, and in front elevation in Figure 3.l
The punch ol' the machine is marked a, it being of the tubular kind, which acts on a solid bed, l, forcing the punchings up the tube of the punch, and delivering them out of a side opening at c.
The punch is iixed to a carrier, d, which is made to reciprocate in guides, e, forming part of .the frame, f, link y, which is moved by a the shaft h, which is driven from a belt applied to the friction-coupling-pulley i.
The xed part of the coupling is marked lc, and thev pulley-part i of the coupling is made capable of a sliding movement on the shait h, so that the rotations of fi may be effective in turning said shaft, orso that the pulley i may turn on the shaft without rotating it, according to the position of the pulley fi, which is controlled by the bent lever l l. The arm l of said lever carries a brake-pad, m., and is acted onto keep the said pad in contact with the part k of the coupling, by a spring, n.
There is arranged,
crank-pin, j, rotated by in 'a mortise through l', a latchpiece, o, passing through the base of the frame, which piece, o, notches upon l', and is kept from falling by the spring p, which is seen in dotted lines, fig. 1, said latch-piece being pivoted on said spring, and pierced with a hole beneath the base of the frame, so that a link from a foot-treadle can be attached to the latchpiece, to draw it down, and thus lever Z l.' to slide the pulley part, i, of the conpling'into driving contact with the part k of the coupling.
Spring q, xed on the end of Z', acts on the latchpull o to keep its notch in gear with the upper corner of the mortise in l.
On the shaft h is xed an eccentric, fr, which, in its rotation, operates to idbrate the lever s, which carries at its lower end a feeding-pawl, iv,-which moves the segment-rack t, which rack is pivoted at a, and carries a pair of griping-jaws, c, which seize vthe material to be puncl1ed,'and by which said material is drawn along over the bed b and under the punch a.
The pivot n secures the piece x, so that it can move with reference to the rack t, and can be pinned to the rack in any desired position relative thereto. The function of lthis piece a: is to operate the rocker y' to disconc-anse movement ofnectthe latch o from arm l', impingement of the end of :v against arm of the rocker to move the latch against the resistance of spring q.
The end of the arm of rocker y, which is acted on by piece as, is provided with a screw, by which adjustment can be made which will affect the time when the latch o is moved, so as to release the lever l l', which, when released, is moved by the spring n to uncouple the parts i It of the coupling, and to bring the brakepad m into contact with part k of the coupling, to stop rotation of shaft h.-
The movement of the pawl w being constant, an adjustable shield, z, is used to vary the amount of movement given rack t by each double reciprocation of the pawl. This shield being made to cover part of the rack, and being made adjustable as to position, will, according to its adjustment under the pawl, allow it `to operate on one or more teeth of the rack, according to the distances which are desired between the holes made by the punch.
To keep the rack from distance greater than that designed to be imparted by the pawl w, a friction-spring, a', is made to bear on the rack, as seen in iig. 2.
To regulate' the distance which the holes are to be punched from the edge of the material, the gauge b', to be fixed in position by set-screw c', is employed; and to keep the stock upon the bed b, and strip the material from the punch, the adjustable piece d' is employed.
The bedrb is secured by a set-screw, so that as its face-end is Worn by the punch, itrcan be refaced by tiling, and readjusted in the machine.
The Iconnection between the link g and the punchbar d is made by a wrist-pin, e', which passes through d, and is screwed into the link g, so that the wrist-pin turns in the punch-bar. y
To disconnect from kthe link g, so as to remove the punch for sharpening',` or to insert a diierent size, the wrifstfpin has to be removed.
The clamping-jaws o are made to be punched by the action of spring f', and when the jaws are brought to the position nearest the punch, a slide, g', operated by means of a lever placed beneath the table on which themachine stands, may be made todepress the rear arm ofthe pivoted upper jaw, and thus release the material from the gripe of the jaws, and hold them open in readiness to receive a new piece to be punched.
Operation.
Suppose the parts of the clutch in the position shown in iig. 1, and the griping-jaws at their nearest proximity to the punch, the shoe z is adjusted so as to allow the pawlw to operate on as many teeth of Ithey rack as is necessary to effect the proper length of feed at each stroke of the paWl, and the piece :u is adjusted so as one arm of rocker y, causing the otherv moving by momentum a to gripe the material .and under piece g',
to stop the machine automatically at some desired position of the rack. Y p
The operator, by movement of the knee, works the lever, which works the piece g', to openthe jawsl v, to cause them to gripe the material to be punched.
The latch-piece o is then drawn downward by the foot-treadle, which causes the rotation of shaft h, and movements of the punch and feeding-pawl, and the rack, till the piece :c moves the rocker y, so as to disengage the latch o from arm l', when spring 'n operates and uncouples ythe 'iction-coupling, and applies the brake m, stopping the machine.
The foot-treadle is then released 'om pressure, and the spring p raises the latch o, while a piece, h', thereon lifts the pawl w out of gear with the rack, so that the rack can be turned to bring the jaws c near the punch by which said jaws .are opened to discharge the punched piece and receive a new one.
In the return of the rack, which is pushed back by the operator, the piece a: moves away from contact with the rocker fz permitting the spring q to move latch o, so that its notch will catch upon the lever l', so that the described operation may .be repeated on drawing down the latch o.
