Specification of Letters Patent.

Patented AprilBO, 1909.

To all when: it may concern:

lie it known that I, MARSHALL HENRY Imnson, a subject of the King of Great Britain, residing at Leicester, in the county of Leicester, England, have invented certain improvements in Punching and Eyeleting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to eyeleting inachinos, and has for its object to provide a novel work-sustaining means which is movable relatively to a rigidly sustained lower eyelet setting device for the purpose of stripping the stock from said device to enable the stock to be fed. The movable worksusiaining means may be elevated and depressed positively, or said work-sustaining means may be maintained normally in an elevated position by yielding means and depressed intermittently by a punch, .presser foot, or other novahlc part.

in some types of oycletin machines in common use the storl: is fed either l) means of the punch, which is moved latera lyafter it has penetrated the stock for forming an eyelet hole, or by means of the lower eyeletselting device, which is moved laterally after the eyelet has been set and while the end of the setting device is still in engagement with the eyelet. in machines having a punch feed it is necessary at each operation of the machine to depress the lower eyelet-setting device for stripping: the eycleted stock therefrom, so that the stock may be fed. This also is necessary in machines in which the stock is fed by the lower eyelet-setting dcvicc, since it is necessary to strip the stock from said device to enable the latter to return to its normal position after feeding the stock. in h'oth of these tpyes of ma- .-hinc.s a great deal of complex mechanism. is required for (lCPICSSlIlg the lower eyeletsetting device and for sustaining said device with sullicicnt rigidity to prevent it from yielding when the upper eycletsetting device is actuated for setting an eyelet in the To overcome these disadvantages l have provided a rigidly sustained lower cyclet-sel tin;- device and work-sustaining means which is movable relatively to the lower cy [cl-setting device for stripping the stock therefrom to permit it to be fed. Moons are tion of a portion also provided for rigidly sustaining the anvil or punch plate during the punching opera- The invention is herein shown as embodied in various forms, and in one form the movable work sustaini means comprises n plate having a shan rejecting into an opening in the end of the mm, the lower end of the shank being connected to mechanism for elevating and depressing the plate. In another form, the work-sustaining plate is shown as yieldingly sustained by means of a spring or friction device, and is adapted to be depressed b a punch or presser foot. The anvil or punch plate may be carried by the movable work-sustaining plate, in which case a portion of the horn acts as an abutment on which the sustaining plate rests during the punching operation, as shown in some forms of the invention, onthe anvil may be fastened directly to the hornflts shown in other forms.

Fig. 1 ol' the drawings IGPXGHGfltS a portion of an ordinary punching and eyeleting ma-- chinc in which designates the base and 3 the horn rigidly attached thereto. A standard 4 projects upwardly from the base and carries the head in whirrh the punch 5, upper lyelet settin; ilcvicc ti, and raceway 7 are mounted. 'lhc horn at its upper end is provided with an upwanlly extending part 8 which all'ords a rigid support for the worksustaining plate 1() when it is in its lowermost position, and said plate has a shank 12 which is slidably mounted in an openinp formed in. the extended part 8 ol' the horn, as shown in Fig. 3. The lower end of the shank 12 is con nected to any suitable actuating mechanism for elevating the work-sustaining plate to remove the eyeleted stock from engagement with the lower eyelet-setting device, as hens inafter described. The sustaining plate H) is provided with a T-shaped slot in which an anvil or puneh plate 13 is movably mounted, said anvil having an opening or passageway 14 into which the lower setting deviee 1G projeets.

Pivotally mounted in lugs 18 irojecting from the standard is a feed arm 20 luiving an extended part .22 which projects into an open ing in the standard, as shown in Fig. 2, saiil extended part being a'lapted to he engaged by suitable means for inipartin; an oscillating movement to the feed arni. Mounted in the outer end oi" the :l'ced am; is the lower setting device it) which isprovided with. a screw-threaded portion .53 in engagement with a corresponding screw-threinled portion formed in a downwardly extending part of the feed arm, which part travels in a slot 2- formed in the upper end of the horn adjacent to the extended part 8. On the threadcd cnd of the setting device is a lock nut which contacts with the under side of the feed arm and holds said device in position after it has been adjusted, the upper end of the setting device being flush with the surface ol the anvil or punch plate when the work-sustaining plate is in its elevated position. A portion of the lower edge of the feed arm. rcst on the horn, as shown in Figs. 2 and 4, and affords a rigid support for the lower setting device when the u per setting device is actuated to upset the s ank of an eyelet to sccure it in thc stoek.

The operation of the mechanism just described is as follows; The feed arin normally occupies the Josition shown in full lincs in Fig. 2% and tire sustaining plate normally rests upon the extended part 8 of the horn, which allords a rigid support for said plate when the punch operates. The acting end of the lower setting device projects through the passageway in the anvil 13, and the stock, which it will be supposed has been provided. with a. hole to receive an eyelet, is placed on the sustaining plate with the hole laterally with. the feed arn'i.

in alinenient with the eyelet-setting deviccs. The upper setting device and puneh are then actuated, and in the downward niovenurnt of said setting deviee an eyelet is removed from the raceway, inserted in the stock, and the end of the shank ol the eyelet is upset by the coi'i ieration of the upper and lower setting devices. The feed arm is then moved laterally into the )osition shown in dotted lines in Fig. 2?, and as theend of the lower setting device is still in engagement with the eyelet that has just been sct, the stock will be fed lUi'Wz-tld into iosition to receive the next eyelet. The enilol the sustaining plate is liil'ur ated at 36 to permit lateral movenient of the lower setting device, and as said device projects upwardly through the opening in the anvil 13 said anvil will he moved When the feed arm has arrived at the end of its lateral inoveincnt. as shown in dotted lines in Fig.

l 23, the sustaining plate is elevated into the position shown in Figs. 2 and 3, thereby stripping the eyeleted stock from the lower setting device, so that the feed arm and anvil can he returned to their IlOllllttl positions, the lower setting device projecting into the passageway in the anvil, but not projecting nliove the surface thereof while the sustain ing plate is in its elevated position. After lhc. 'l'c d arm has been moved baek to its normal position the sustaining plate is then lowered to again. rest on the projecting part 8 ol' the horn, and the same operations are repcalcd l'or inserting other eyelets.

Fig. 5 illustrates a modification ol' the mechanism shown in Figs. 1 to 4, inclusive,

. and in this form the feed arm 20 carries the work-sustaining plate 11 and also the lower suiting device Hi, the extended part 9 of the horn living provided with a stationary anvil 27 on which the much acts.

in Figs. 6 to 9, inc usivc, is shown a modified form of the invention which is to be used in combination with a machine in which the punch niovcs laterally for feedinp the stoek, as in the machine shown and (escribed in UnitedStates Letters Patent N0. 478,759,

dated 'uly 12, 1892. In this form of the invention the upper end of the horn is provided with a de iression or recess 30 to reeeive the siistainoig plate 10", and projecting downwardly from said Jlate into a vertical opening 3:! formed iirtlie horn is a hollow shank 12. A coiled siring 34 is confined within the hollow shan l-z and bears at ,one end against the top wall of thehole in the shank and at its other end against a retaining Jlate 36 which is detachably secured to the horn and forms a closure for the opening in which the shank of the sustaining plate moves. The spring holds the sustaining plate normally elevated as shown in Fig. 6, so that the end of the lower setting device will not project above the surface of said plate, and the elevated v is controlled by an ad usting device corn- )rising a rotatable stud 37 which is mounted in a horizontalopeningin. the horn, as shown in Fig. 6. The stud is provided with a shoulder 38 formed by cutting away a portion of the stud, and this shoulder is adapttion.

trolled.

ed to engage the lower edge of a recess 40 formed in the side of the shank 12 to thereby limit the upward movement of the sustaining plate. The stud is also provided with a slot 41 into which the end of an adjusting screw 42 projects, said screw being mounted in the horn and provided with a lock nut 44 for holding it in adjusted posi- Thc side walls of the slot in the stud are engaged by the screw 42, which prevents the stud from being moved transversely of the horn, and the end of the screw is rounded and bears against the curved bottom wall 45 of the slot, so that by adjusting said screw the position of the shoulder 3-8 on the stud may be varied and the elevated position of the work-sustaining plate may he con- The sustaining plate 10 is providcd with an anvil or punch plate 46 on which the punch. operates, and. is also providcd with an opening or passageway 14 into which the lower setting device 16" extends. The lower setting device 16* is monntcdin an opening in the horn, and at its lower cud is engaged by an adjusting screw 48 that en bles the elevated position of the device to 'hi -varied, and a locking sci-cw so which engages the side of said sethohls it in adjusted position. Dctnchahly secured to the outer end of the sustiiining plate is a plate 52 which prevents dust from collecting in the space between the lower surface of the sustaining plate and the bottom of the depression or recess 30.

In the ops ration of this form of the invention the stock, which has been provided with an eyelet hole, is placed on the sustaining plate with the eyelet hole in alinement with tho eyelet-setting devices. An eyelet having how set the punch descends to form. a hole in the stock and forces the late 1O downwardly against the stress 0ft 1e sprin 34-. After the sustaining plate has reache the limitof its downward movement, which in this form is the bottom of the depression 30, the punch, is thereafter retracted slightly and is moved laterally for feeding the stock, the sustaining plate moving upwardly as the punch. isretracted, so as to holdbthe stock in (nigagement with the end of the punch, and also to strip the cyeleted stock from the lower setting de When the punch arrivcs at the rod of its lateral movement the usual prcsscr foot 6 such shown in Figs. 1 1 and i2, is actuated for stripping the stock from the punch and. for forcing the sustaining plate downwardly to expose the end of the position of the plate I lower sr tting device.

lhe punch is then retracted and moved back to starting position and the upper setting device is moved downwardly, said device removing an eyelet from the raceway, inserting it in the hole in the stock, and forcing it into engagement with the lower set which upsets the end of the shank of the eyelet to fasten it to the stock.

Fig. 10 represents a modification of the form shown in Figs. 6, 7, 8 and 9, and in this construction, instead of yicldingly maintaining the stock-sustaining plate 1O normally in its elevated position, means are provided for positively moving said plate upwardly to strip the cyeleted stock from the lower setting device and to hold the stock in engagement with the punch during the feeding movement, said means comprising a rod 61 connected at its upper end to the shank 12 and at its lower end to suitable actuating mechanism, not shown. liricticnal means comprising a spring-pressed plunger 64 is ai'leptcd to bear against the surface of the shank 12 for holding the sustainin plate elevated until it is again depressed y the action of the prcsscr loot.

Another form of the invention is illustrated in Figs. 11, 12 and 1 S, and in this form a stationary anvil 70 is fastened to the horn by screw 71, said anvil being surrounded by a movable stock -sustaining plate 1O provided with an opening or passageway 14 to receive the lower setting device 16 and also having a hollow shank 12 which moves in a vertical opening formed in the horn. The shank incloses a spring 34* which holds the plate 10 normally elevated, as in the corn struction shown in Fig. 6, the operation of both of these forms bein substantially the same, except that in the Form Shown in Fig. 11 the punch does not contact with the anvil during the lateral movement of the punch. The punch 5 /which is used in this form of the invention is provided with a downwardly projecting lug 72 which engages the plate l0 when the punch moves downwi-trdly, so as to depress said plate flush with the surface of the anvil.
