EYELETING-MACHINE.

SPECIFICATION lforming. part of Letters Patent No.y 259,100, dated June 6, 1882.

- l nppneationaled February 27,1ss2. (Model.)

To all whom it may concern Be it known that I, CHARLES A. CoRMA'N.'

of Cochit-uate, in the county of Middlesex and State of Massachusetts, haveinvented certain new and useful Improvements in Punching,

Eyeleting, and Beading Machines; and I de` clare the following to be a description ot' my said invention sufficiently full, clear, and exuct to enable others skilled in the artto which it appertains to make and use the same, reference being had to the accompanying drawings,

which form a part of this specilication.

The objects-v Qf my present invention are, rst, to provide a convenient and practical machine adapted for punching holes, embossing orbeadlng theleather about the openings, and

' inserting the eyelets ata singleoperation second, to afford means for delivering the eyelets with their flanged ends uppermost and inserting'them from the top of the work; and,

third, to afford facilities for the ready and convenient adjustment of the mechanism to various lengths of movement or spacing of the holes and to cause the eyelet-settin g devices to accurately follow the punching devices.

I attain these objects by mechanism constructed and organized for operation substantially as illustrated, the several essential features of my invention being set forth and eX- plained in the following description, and the particular subject-matter vclaimed being hereinafter definitely specified.

In the drawings, Figure l represents a'ront view -of my punching, eyeleting, and beading machine. Fig. 2 is a side view ot' the same. Fig. 3 is a plan or sectional view at line ma. Fig. 4 is a horizontal sectional view at line'g/ y. Fig. 5 is an end view of the punch-bar. Fig. 6 is a plan view of the eyelet box or hopper andy the delivering-runfor conveying the eyelets to the setting devices. Fig. 7 is a transverse sect-ion ot' the eyelet-run atlineaz, enlarged. Fig. Sis a view of the operatinglevers for workin g the eyelet-sets.

In the reference to drawings, A denotes the main frame, of suitable form for supporting the operating devices. l

B indicates a swinging head-frame, pivoted to the main frame at b, and provided with suitable bearings for carrying the punch-spindle D, which latter is arranged to have a recipocating and a rotating action.

C indicates the operating-shaft, mounted in bearings on the frame A, and provided with suitable cams for operatin g the several parts.

E indicates a horizontally-swingingframe, upon which the eyeleting mechanism is supported, said frame being hinged to swing the eyelet-sets toward and ffrom the punch devices.

The head B is made with a guide-bar, B', in which works the slide B2, operated byacrank and pitman, c,'at the endV of the shaft G,`by -I means of which the punch bar or spindleD is reciprocated up and down, while a swinging or oscillative action is imparted to the head B Yby means of a cam, C', which works against a friction-roll attached at one side ot' said head 'and against a spring-lever, B3, at the other side thereof, the roll and lever causing the vhead B,with i-tspunching mechanism,to swing Rotary any desired shape for embossing or beading the surface of the leather around the opening formed by the punching die or. cutter.

F and F' indicate jaws or guides for holding the work in proper position to receive the punching and eyeleting mechanisms. Said jaws are curved to correspond with the swing of the head B, and the upper jaw, F, is attached to a lever or arm, F2, fulcrumed to the side of the frame A, and provided with a spring, f, for pressing the jaw with a yielding force upon the top of the work. By depressing the rear end of the arm F2 the work is released from between the jaws. 1

' The presser-jaw Fis automatically raised at the proper moment of feeding Y'forward the work by means of an eccentric or cam, G, on the shaft C, which operates a lever, G', that engages with and depresses' the arm F2. The lower or supporting `iaw, F', is fixed or stationary in position.

D3 indicates the bed-piece or lower punching-die, which is vformed as shown, and ad- 'justably secured in its supportingbracket at IOO 7o from side to side by the action of the cam C',

the lower part of the swinging head B, said bed moving in concert with the punch forearrying forward the work.

The frame E, which supports the eyeleting mechanism, is hinged at its rear end to the main frame A, the bracket or standard E', 'which supports the hinge, being connected so as to afford forward or rearward adjustment of the eyeleting devices to bring the clinching dies into accurate alignment with -the l unching-dies.

A spring, c, is provided for drawing the forward part of the frame E toward the head B, andan adjusting-screw, E2, is arranged through said frame E, the end of which strikes the side of frame A and forms a stop for arresting the movement of the parts at the proper position in relation to the head B and punchrod D.

The eyeletin g sets or dies I and J are supported in suitable bearings on the forward part of the frame E, and are operated up and down for clnching or setting the eyelets by means of a pair of rocker-shafts, K K', to which the die-bars are connected by arms I J The shafts K K are connected together by arms K2, and are operated bya cam, L, on the shaftC, from which they receive motion through the train of arms or levers illustrated in Fig. 8, where L is a lever pivoted to an extension of the bracket E', and provided with a pin or roll, l, which runs in the groove ofthe cam L, and K3 is an arm connected with the rockershaft K and operated by said arm L.

The connection between the arms L and K3 is formed by an adjustable sliding fulcrumblock, L2, whereby the relative length of leverage can be varied for regulating the movement of the eyelet-setting dies I and J, as desired.

The lower eyeleting-die, I, is provided with a fixed pin or picker-stud, i, for receiving and Y supporting the eyelets, which latter are fed to the dies with their flanged ends upmost and above the work, the picker or receiving pin i passing through the hole in the leather or fabric before it takes the eyelet from the end of the run M, the work being operated upon with the finished side upward and in view of the operator.

The upper eyelet-set, J, is provided with a hole in its end for the reception of the pickerpin t when the dies are brought together.

By dispensing with a movable picker-pin and setting the eyelets directly on the fixed picker t perfect cliuchin g of all the eyelets is insured. The eyelet-receptacle M is mounted at the upper end of an arm, M2, pivoted on the swinging frame E near its lower edge, so that the receptacle or hopper M and deliverychute M can swing back and forth for bringing its end over the picker-pin 1'-, the arm being drawn forward by a spring, M4, and forced backward by an incline or projection on the side of the cam L, acting against a friction roll or lug on the side of the eyelet-box.

An adjustingscrew, N, is arranged, in connection with the arm M2, for regulating its forward movement and stopping the end of the chute or guide M in proper relation to the setting-dies. The chute or guide for feeding or delivering the eyelets is made as indicated in Figs. 6 and 7. Side grooves are formed therein to carry the eyelets by their flanges or with their broad end upmost, the lower end of the eyelet hanging free above the bottom of the channel. The channel hasaV-shaped entrance at the bottom of the box M', and a small spring, m, at the point of delivery prevents more than a single eyelet being discharged at each operation of the setting-dies.

An agitator is arranged within the receptacle, which may be operated by a ratchet and pawl, O, or otherwise, as preferred.

The driving-pulley Pis mounted to run loose on the shaft C, and is connected thereto for operating the mechanism by an automatic stop-clutch arranged to throw oi` after the shaft has made one revolution. This clutch is in the present instance formed of a springdog, Q, pivoted on the shaft and arranged to engage with a notch or recess, n, formed in a suitable rim or hub of the pulley l?.

A swingarm,lt, having an incline and shoulder, r, acts to throw the end of the dog-piece out from the notch n and arrest the motion of the shaft O. The arm It is operated or swung outward from the dog Q by a rod, S, connect ing the rocker R' of the arm R with a suitable treadle. By holding the treadle depressed the motion of the machine can be continued.

rlhe parts of the machine being properly adjusted and the driving-belt running on the pulley P, the operation of the mechanism is as follows: The operator, by pressing down the arm F2, raises the presser-jaw F and inserts the work between the jaws F F. He then depresses the treadle mechanism to release the clutch and put the shaft into action. The punch-spindle D descends, forcing the punching-die through the leather. The upper jaw, F, is then raised by the action of the eccentric G and lever GY', and the head B and punchspindle swing toward the left by the action of cam C', carrying forward the work with it, and also forcing outward the swing-frame E. At the end of this movement thejaws F close together and hold the work, while the head B, with punch D, recedes to its former position, and the eyelcting mechanism moves up to the position lately occupied by the punch, the pin t' is raised through the hole in the leather or fabric and passes through an eyelet, picking it from the end of the chute M, which latter immediately moves back out of the way, and the eyelet is set into the hole and clinched as the dies are forced together. The machine then stops by the automatic action of the clutch; or, if the cast-off bar R is held back, the operation may be indefinitely repeated and a hole punched and eyelet set in by each consecutive revolution of the shaft C, the holes being punched and eyeleted at regular intervals corresponding to the swing movement of the head IOO IIO

B. The spacing of the holes may be 'increased or diminished by adjusting-screw d. The surface of the leather is beaded about the hole at the same time it is punched by the end ofthe spindle D revolving thereon While the dies. are pressed together. If desired, the punching and eyelcting devicesY can be employed without the mechanism for revolving the punchspindle D; or the punch can be used without rotation by removing the baud h from the pulleys Dl and H'.

I am aware that combined punching and eyeleting machines have been heretofore made in which the punching-bar was mounted on a Swingin g supporter and had lateral movement for feeding forward the work. Hence I do not herein make claim broadly to such features of operation. p

What Iclaim as of my invention, and desire to secure by Letters Patent, is-

l. The combination of the revoluble beading and punching bar, its cuttingbed, the movable head provided with bearings for supporting and guiding said punching-bar, and an operating mechanism whereby rotating, reciprocating, and lateral vibratory action is simultaneously imparted to said. punch-bar, substantially as and for the purposes set forth.

2. In a machine for punching, beading, and eyeleting at simultaneous operations, the combination of a reciprocating revoluble punch mounted on a laterally-swinging head-piece and provided with a cutting-die and beaded end face, a pair of eyelet-setting dies mounted on ahnged frame adapted for side movement to allow the alternate advancement of the punch and eyelet-setting dies to a common position in relation to the Work, a guiding and holding presser or jaw mechanism adapted for automatically retaining and releasing the work, and means for adjustingthe relative swing or lateralmovement of the parts for increasing and diminishing th-e spacing between the holes, substantially as set forth. v

3. The combination, with the frame A and swinging head-piece B, carrying punchingdies D D3, of the laterally-swinging frame E, carrying the eyelet-setting dies I J, and the mechanism for operating the same, substantially as set forth.
