EYELETlNG-MACHINE.

lSPECIEICA'JIION forming part of Letters Patent No. 422,351, dated February 25, 1890.

To a/ZZ whom, it may concern:

Be it known that I, FRANK W. MEERICK, of Somerville, county of Middlesex, State'of Massachusetts, have invented certain new and useful Improvements in Eyeleting-Machines, of `which the following is a specification, reference being had to the drawings accompanying and forming a part hereof, in which- Figure 1 is a front, Fig. 2 a side, and Fig. 3 a rear, elevation. Fig. et is a top view. Fig. 5 is a detail showing the cam which operates the upper set. Fig. 6 is a detail of the yoke and cam which operate the punch. Fig. 7 is a detail of the arm and its operating yoke and cam which actuate the die, as also the punch, laterally7 to feed the stock forward, and showing, also, the mechanism by which the len gth of the feed may be regulated or changed.` Fig. 8 is a section of the eyelet-box, and show-` ing the eyelet-agitating device. Fig. 9 isa detail of the cam which operates the presser-g Figs. 10 and 11 are vertical sections ofi the under-set bar, showing the method of? holding down the spindle during the downward movement of the bar. Fig. 12 is a section on line 0J Fig. 10. Fig. 13 is a section on line g g, Fig. 2. Fig. 14 is a section on line y y, Fig. 2. Fig. 15 is a plan view of thefy arm which carries the die.

The object of my invention is t-he construcf tion of an automatic eyeleting-machine which? mayhave a large table unobstructed by the eyelet-hopper, race-way or other parts, a positive punch-feed which cannot ,fail to feed. even the thinnest material and which may bef speedily Vadjusted without stopping the ina-z chine, if necessary, so as to vary the length of the feed, and a hopper and its raceway ar-l ranged beneath the table of the machine andi so mounted asto he readily swung back wheny it is desirable to use the machine for punching holes only without setting eyelets in them g and my invention consists in the construction. and arrangement of the parts of the machine,l whereby the hopper and its raceway may be placed underneath a table, thus permitting a large and unobstructed table for the reception of the work. Y

My invention further consists in the construction and arrangement of the punch-feed so that not only the punch has a lateral feed movement, but also the die with which the punch co-operates, thus insuring a positive feed without danger of missing even the thinnest or lightest kind of material.-

My invention further consists in the mechanism for imparting to said punch and die the lateral feed-movement, as also for adjusting the length of the feed speedily and easily, so

that, if desired, the operator may with ease.

I have shown my invention in they accomi panying drawings and embodied in the. best form now known to me, and I will describe the same, using like letters of reference to indicate like parts. y

A represents the frame or standard of the machine, and may be varied in form, as desired. In a bench-machine a frame adapted to be .placed ony a bench would be used.'

B is the Amain shaft, which is journaled in the standard and` is iittedrwith a belt-pulley C, and from which all the operating parts of the machine are directly actuated. The front end lof the main shaft is provided with a crank-wheel d, which is pro vided with a crankpin carrying a pivoted link b, the other end of said link being pivoted to a stud on the under-set bar d. The bar d is mounted in a vertical raceway in the front of the standard, (see Fig. 1,) so that as the crank-wheel a revolves the under set is reciprocated vertically.

g is the upper set, which is mounted in a bar I), curved at its upper end, the shank of which is set in suitable bearings on the rear of the standard to permit of vertical movement. (See Fig. 3.) The said shank or straight portion of the bar D is provided at its lower end with a curved piece h", which projects through a vertical slot s in the standard A, (see Fig. 3,) and carries at its ICO lower end a cam-truck, which travels in the cam h on the main shaft. By this arrL ngement the upper setg is `given a vertical movement, and is prevented from lateral movement by the said vertical guide-slot in the standard, through which the piece 71, projects. The presser-foot k is also mounted, as shown, on a similar goose-neclt-shaped bar E, the shank of which is also mounted in a similar bearing on the standard A and beside the shank of the goose-neck D. (See Fig. 3.)

The lower end of the shank E is provided with an arm h", which rests on the cam hw, set on the main shaft, (see Figs. 3 and 9,) and by this means the bar E and presser-foot are raised at each revolution of the shaft to permit the feeding forward of the stock. A spiral spring Z encircles the bar E, the upper end of said spring resting against the guideway or bearing and the lower end against a collarm on the bar. (See Fig. 3.) rlhe spring Z acts to keep the bar E pressed down against the cam h10,.and thus as the cam revolves the presser-foot is given a vertical movement.

The punch is shown at n, and is also mounted in a goose-neck-shaped bar H, which is likewise set in a suitable bearing on the frame, so as to permit of its vertical movement. The shank of the bar H is attached by means of a stud and right-and-left-hand adjustingscrew (see Figs. 3 and 6) to a yoke p, which receives a shield-shaped eccentric q, by means of which the punch is reciprocated vertically, with two periods of rest during each reciprocation-that is, at each revolution of the shaft. By this means the punch is brought down to cut a hole in the stock, and remains down while it is being moved laterally to feed the stock, after which it goes up and remains up while it is moved laterally back to the point from which it moves down again to punch the next hole. The bearings in which the bar H slides are shown at t, Fig. 4, as split and provided with clamping-screws, by which any wear of the bearing may be taken up, if desired. The bar H carries the arm a', the rear end of which is provided with a sleeve through which the bar passes. A block b on the bar H is received in a vertical slot c in the sleeve of the arm a. By this arrangement the bar H may have a vertical movement relatively to the arm a', while the two will move laterally together.

The forward end of the arm a carries a die-block d', adjustable thereon by means of screws, (see Fig. 15,) which carries a die f', which may be of wood, metal, or other suitav ble material. The die f projects upward through a slot g', Fig. fl, in the table and cooperates with the punch n to punch a hole in the stock for the reception of an eyelet or similar article.

rlhe slot g in the table permits the lateral movement of the die f in co-operation with the punch to feed the stock, and as the feed movement occurs when the punch and die are in contact and after the punch has passed through the stock it will be clear that the feed is positive and that very thin and light stock will be fed with the same certainty as thick stock.

As will be obvious, the length of the feed will govern the spacing of the eyelets, or, rather,the spacing of the punch-holes in which either eyelets or hooks are set. The mechanism for controlling the length of the feed is one of the essential features of my invention, and consists, essentially, of a lever having a movable fulcrum, whereby, by shifting the fulcrum, the feed movement may be varied.

I will now describe the particular mechanism shown in the accompanying drawings by which the feed movement is governed in amachine like the one shown employingapunchfeed. For the purpose of giving the punch and die a lateral feed movement, I provide a lever h', (see Fig. 7,) the upper end of which is pivoted to a projection am on the sleeve of the arm a', (see Fig. 2,) by means of a sliding block. (Shown atj,Fig.7.) The other end of this lever is provided with a yoke 7c', which receives a shield-shaped eccentric Z on the main shaft. The central portion of the lever 7L is provided with a curved slot m', which receives a stud u 011 the end of the lever p', the other end of said lever p being extended in front of a graded segment or curved projection r', secured on the standard of the machine. 'lo this lever a rod s is secured, the lower end of the rod being pivoted to a treadle r, so that the operator, by movement of his foot on the treadle, may raise or lower the lever p', thus raising or lowering the stud n in the slotm, and thus changing the fulcrum of the lever 7L and varying the throw of said lever. Since this lever h moves the arm a and the bar H laterally it will be clear that the lateral or feed movement of the dief and punch n will be varied by a variation of the throw of the lever 7L', and that consequently the length of the feed may be adjusted or varied as desired. For the purpose of setting theI lever 1) so as to fix the throw of the lever 7L at a given amount, or of gaging the throw of the lever p', I provide a slotted curved piece 9, which is pivoted by an arm to the standard on the pivot of the lever p and projects in front of the segment 0". The piece t" is secured to the segment o" by means of a headed pin 1513, which projects into holes in the segment fr. (See Fig. l.) On the curved piece t are adjustably secured an upper and a lower block t, which limit the movement of the lever p so that two different and definite lengths of feed may be obtained, and two different spacings may be obtained for eyelets and lacing stud-holes, as required on the Hap of a shoe.

)Vhen the operator by means of the treadlerod s holds the lever p against the lower block, a short feed will result, such as is required in setting the eyelets to receive the lace in the lower part of a shoe-flap,whilc by shifting the lever p till it bears against the IOO ITO

upper block 10 a longer feed will result,'y

such as is desired in punching the holes to receive the lacing-hooks in the upper part ofl the shoe-ap. In this way the space between the eyelets or punch-holes may be varied instantly and the holes distributed evenly without stopping the machine. By moving the piece t, which may be speedily and accurately done by means of the pin 13 and graded scale on the segment r', the path of movenient of the lever p', and consequently a given variation of the length of feed, may be provided for, so that when the pin 1513 is set opposite the ligure 5 of the scale on the segviz., iirst, on a shoe-flap of a given size av part of the holes punched may have one spacing, while the remaining holes may have another spacing, and, second, on a shoe-flap of a larger size the same number of holes bearing the same relative positions to each other and to said flap as the holes in the smaller ap bear to it may be-properly spaced and spread out as required on said larger iiap by a simple and speedy adjustment of the fulcrum of said lever.

As it frequently happens that when the feed is lengthened it is desirable, as in shoeflaps, to punch holes only for the recept-ion of lacing-studsand not `to set eyelets in the holes, I have provided a rod a2, which is vfast at one end to the rear of the lever p and at the other to a sliding block p9, which moves in ways on the standard. (See Figs. l0 and 12.) A slot p10 in therear face of said setbar contains a pivoted latch 198, the lower end of which is pressed outwardly by means of a spring p7 throwing the upper hooked end inwardly against the spindle of the under set which takes the eyelets from'the raceway.

A Vhen the under-set bar has moved upwardly spindle down in its socket.

to set an eyelet, the spindle is forced downwardly against its spring, as shown in Fig. ll, and the hook of the latch p8 snaps over the base or seat p11 of the spindle, holding the The spindle remains in this position until the set-bar nears the end of its downward movement, when the free end of the pivoted latch slides under the block p9 and frees the latch from the spindle, thus allowing the spindle to rise in time to take an eyelet on its upward movement. By this arrangement the spindle is held within its socket while it is passing down past the end of the eyelet-raceway x2, and so is kept out of contact therewith. If now the block p9 be slid down, so as not to come in contact with the latch p8 at any part of its movement, the spindle will be held down in its socket continually and the machine may be operated without taking the eyelet-that is, it may be used for punching holes without setting eyelets in them. Since the block pf is connected by the rod a2 with the lever p when the lever p is moved downwardly by its treadle, the feed mechanism is not only shifted, as above described, sov

as to space the holes differently, but the spindle of the under set is at the same time locked down and prevented from taking the eyelets, 1

and thus the operation of the machine in setting eyelets in the lower part of a shoe-Hap and cutting holes in the upper part with different spacing is continuous.

The eyelet-hopper f2 and raceway x2 are mounted on an arm Z22, which is pivoted at d2 to a stud on the standard A, so that it may swing toward and from the front of themachine. The arm b2 iiares at the top or upper end, as shown at Fig. 2, so as to present a proper support for the hopper and raceway,

and the arm is so constructed that when it is swung forward or down the lower end of the raceway will be in position to deliver an eyelet to the lower set as the set moves upward past it, and as soon as the sethas takenv an eyelet a cam projection h2 on the front of the arm b2 comes in contact with 'a cam projection or web 3'2 (see Fig. l0) on the rear of the set-bar, so that the further upward movement" of the set-bar throws the arm b2 and the raceway and hopper back out of the way.

A spring 792, fast at one end to the standard and at the other end vLo the arm b2, acts-to pull the arm down or forward again as soon as the set has descended, and thus to bring the raceway into position to deliver the succeeding eyelet to the under set. The raceway is ofthe usual form, and is substantially in crosssection a T-shaped or open slot, (see Fig. 14,) while the hopper also may be of any'wellknown form, the precise form of hopper used not being essential to my invention..

For the purpose of agitating the eyelets in the hopper, I have provided a shaft Z2, which may be used, if desired, and which is provided at one end with a brush ZT inside the hopper. (See Fig. S.) The other end of said shaft Z2 is connected by a universal joint with a shaft Z", journaled in a lug Z10 on the arm b2. The lower end of the shaft Z9 carries a pinion which meshes with a rack Z6, secured to a bracket on the standard, and which at each forward and backward movement of the arm b2 operates to revolve the brush Z7,`and thus agitate the table where the eyelet is placed in the work.

Sufficient room is therefore gained to place the hopper and raceway wholly under the work-table K, and still have sufficient pitch to the raceway to insure the fall or delivery of the eyelets down the same from the hopper.

IOO

IIO

By this arrangement a large and unobstructed work-table is obtained which greatly facilitates the use of the machine and enables it to be used in setting eyelets in large work in which, so far as known to me, eyelets could only hitherto be set by foot-power or by a slow hand process.

The treadle I (see Fig. 2) is connected with a shipper mechanism of well-known construction, so that the operator may stop and start the machine by pressure of his foot. A proj ection 15 from this treadle is pivoted to the lower end of a vertical rod r6, the upper end of which rod is secured to the arm hs on the presserfoot bar E. (See Fig. 9.) By this mechanism the operator is enabled to lift the presser-foot by depressing theheel of his foot which is on the treadle I), while by depressing the toe of said foot the shipper-leveris shifted and the machine started. To permit of this latter movement, the upper end of the vertical rod r6 is so secured to the arm 71,8 that' it may slide vertically therein.

The arm a', which supports the die f', is of the yoke shape, in cross-section, (shown in Fig. 15,) in order to accommodate the eyelet hopper and raceway and to permit the latter to be placed centrally in the machine.

Vhat I claim isl. The combination, in an eyeletingmachine, with the vertically-moving under set and its bar, of an eyelet hopper and raceway mounted on a movable support or arm, said support being provided with a cam projection which co-operates with a similar projection on the under-set bar, whereby as the under set moves upward the eyelet hopper and raceway are moved backward, for the purposes and substantially as shown and described.

2. In an eyeleting-machine, the combination, with an under set having a springmounted spindle, oi` a latch co-operatin g with said spindle carried on the under-setbar, and a sliding block arranged to bear on said latch to release the spindle at acertain point in the movement of the under-set bar, and means for operating said sliding block, substantially as shown and described.

3. In an eyeleting-machine, the combination, with a set having a spring-mounted spindie, of a latch arranged to co-operate with said spindle to lock the spindle within its socket, a sliding block arranged, when in its operative position, to bear on the latch to free it from the spindle, and treadle-operatin g mechanism for said block, substantially as shown and described.

4. In an eycletiliginacliiiie having a laterally-moving punch and die, the combination, with an operating-lever for imparting to said punch and die their lateral movement, of a movable support to which said operatingle ver is fulcrumed, two stops, and a movable part by which said stops are carried, whereby said stops are adapted to be simultaneously moved to change the position ot the move' ment of said support, substantially as shown and described.

5. In an eyeleting-machine having a pivoted arm carrying the eyelet hopperand raceway, the combination therewith of a stationary rack, a shaft, and pinion co-operating with said rack, said shaft being journaled on the said arm, which carries the hopper and raceway, and being connected with a brush or equivalent device in the hopper, whereby the movement of the hopper-supporting arm will agitate the eyelets, substantially as shown and described.

G. In an eyeleting-machine, the combination, with an upper set and presser-foot above the table or worklsupport of said machine, of a vertically-moving under set and a movable eyelet hopper and raceway arranged beneath said table or work-support and thus entirely out of the way of the operator.

7. In an eyeleting-machine, the combination, with the upper set and presser-foot above the table or work-support of said machine, of a verticallymoving under set, an eyelet hopper and raceway arranged beneath said table or work-support, a pivoted arm by which said hopper and raceway are carried, and mechanism, substantially as described, for moving said pivoted arm to change the posit-ions of said hopper and raceway.
