LEATHER-PUNCHING MACHINE.

Patented Apr. 1t), 1910. Serial No. 183.007.

To all wilma it may concern:

13o it known that I, Cananea l. S'nmnox, u citizen of the United States, residing at l.l nn, in the county of Essex and State of li nssachusetts, have invented certain new and useful Improvements in Leather-Punchine Machines; and l do hereby declare the following to be u full, clear, and exact description of the invention, such as will en` able others skilled in the art. to which it ap wrtaina to make and use the same.

he present invention relates to leather punching machines and particularl to machines for forming ornamental per orations or cuts in the various parts ofshoe u pers in o'rder to give lsuch parts a finishedand pleasing appearance in the completed shoe.

The object, of the invention is to provide a machine of the class referred to of iinprovcd construction and mode of o ration.

Leather punching machines w ich are used to form ornamental perforutions or c uts in thc tips or other parte ot a slice upper usually comprise a reciprocating punch und means for intermittently feeding the work beneath thc punch, and the various features of the present invention relate to ccitain improvements in the means for feeding and ruiding the work beneath the punch and for oldiiig it in proper position.

One fcuturc of the invention consists in an improved means for supporting and actuutiiur the presser foot which bears upon the wort in roximity to the unch. In accordance witi this feature otpthc invention the prcsscr foot. is mounted upon the lower end of a vertically movable rod and is arranged to bear against tho work beneath the punch- .stock upon which the punch is mounted and in close proximity to the punch, and means arc provided for raising the rod and for movingr its lower end laterally in order to rcmove the presser foot from beneath the punch-stock. The. provision of means for moving the lower end ofthe rod, upon which the presser foot is mounted, laterally as it is raiised allowstbc presser foot to bear upon the work close to thc point. at which it is acted upon bv thc punch and at the same tinic thc presser foot can be raised clear of thc work when desired without contacting with thc punch-stock. ln the preferred embodiincnt of this feature of the invention hereinafter described. the upper cud. of thc I rod upon which the presser foot is mounted is arranged to reciprocate through u pivoted Va change is made in the size or bearing and the rod is swung during its u ward movement iii order to remove tio presser foot from beneath the punch stock y the engagement with a fixed part of the machine of a pro'ection on the lower end of the rod. llt will understood that the rod may be otherwise mounted and actuated wit iout departing from this feature of my invention broadly considered althou h the construction above referied to is t e one which ll prefer to use on account of its simplicity and ease and certaintyr of o ration an is the best construction which have been able to devise.

Another feature of the invention consists in an improved adjustable edge ga're and means for locking it in adjusted osition. In accordance with this feature o the invention the edge gage is so mounted and supported as to be ca able of two adjustments, one toward and rom the punch transversely to the line of feed and the other toward and from the punch in the line of feed and a single means is provided for lockin the edge gage in adjusted osition. It is esirable in machines of this c ass that tho'edge ga be located as near as possible to the punci in order that the perforations or cuts ma be located at the same distance from the e ge of the work whether the edge of the work is straight or convexly or ccn-I cavely curved. The provision of the ed gage above referred to,l adjustable in two directions, and a single means for locking the guage in .ition, allows the rgerntor to rea ily an quickly adjust the ge to bring: it into the desired position w enever shape of the punch. The construction which I prefer to use and which embodies this feature of my invention in a simple and convenient. form, comprises an edge gage formed upon or secured to an arm pivotally mounted in a block so as to be capable of a swinging movement to adjust the ed gage toward and from the punch in the line of feed, a support upon which the block is mounted so becapable of movin thereon to adjust the edge ge toward an from the punc i transverse y to the' line of feed and a set screw for locking the block and arm in position.

Another feature of the invention consists in an improved means for securing a cutting block to the work support beneath the punch. It is necessary to change the position of the cutting block frequently' in order as to.

llt)

Bti

'canbe to-bring a fresh surface beneath the punch. and in order to enable the oizierator to do this easily and quickly l provide u plurulity of clamps for clampingr the cuttingr hlocr on the work su iport, und menus conven iently accessible lay the operator for simultaneously actuating the clumps. In the preferred form o f this feature of my invention the cutting block is located in u slot in the Work sup rt, the clamps` are mounted in holes in t work support and arranged to bear against the side of the cutting block, and the means fpr actuating the chnnpr is located beneath the work support. 'lhe means for actuating the clamps is thus easy 0f access b the operator and the clamps ui y actuated without removin v any 0f e parte ofy the machine whenever it is desired to change the position of the cutti block.

other feature of the invention consists in an improved means for intermittent] feeding the work. In accordance with this: feature of my invention feeding mechanism acting to feed the work intermittently to the unch is provided, and means controlled b e operator for varying the extent of de individual feed movements durin v the tion of the feedin mechanism. ien edge of the work eing operatedupon is curved the work is swung b the operator as it is fed beneath the puncli in order to bring the -work into the proper position. The result of the swinging movements which am imparted to the work 1s to cause the edge of the work to be moved a greater or a less distance than the movement which is imparted to it by the feeding mechanism, a greater movement being imparted to the edge of the'work when th eonvexl and a lese movement bein iniparted reto when the ed e is curveilI concavely. It will be evident t at if the length of the individual feeding movements be kept constant the distances between ,successive rforations will vary, the perforntions placed at ater interva s when the edge o the wor is eonvexly curved than when the edge of the work is straight or concavely curved. The provision of means \under the control of the operator for varying the len h of the individual feed movements enab es the operator to increase the length of the feeding movements when tluedge of the work is concavcl curved and to decrease the len h of the feeding movements when the e of the work is convexly curved, theregy causin the perforations to be s uced at equal istances apart regardless of) the curvature of the work. 0n account of the simplicity und compactness of auch a construction and its certainty of o ration, I prefer employin a feeding mec anism which comprises a eed wheel arranged to engage the work, and l e edge is curved ration of the machine,

cespiti mechanism for intermittently actuatinc, the feeding wheel. ln the specific. emhodunent of this feature of my invention hereinafter described the feed wheel is intermittently actuated through suitable conncctions from nn oscillating lever provided with u fulcrum, the adjustment of which acts to vary the extent of the individual feed movementsl imparted to the feedin Y wheel and means are provided whereby tfie fulcrum can he ud- )usted to chan individual f m movements an hy which the fulcrum can 1 moved hv the o ierator to vary the length ofthe individual iecding movements during the operation of the machine. rllhe arrangement of this oseillutin lever and its ad'ustable fulcrum in u fcccl ing` mechanism, believe to be new, irrespective of the particular form of feeding device or devices which are actuated from the lever, and I accordingly consider a feature of my invention to consist in a feeding mechanism for a leather punching machine consisting of s feeding device, an .oscillating lever and suitable connections for intermittently actuating thc feedin adjustable fulcrum for saill lever, the adjustment of which varies the extent of the individual feeding movements the feeding device, whether means are provided for ad'usting said fulcrum to chan the normal length of the individual feed movements or means under the control of the o xrator for ad'usting the fulcrum during t e o ration oil the machine to vary the extentr ofpthe individual feed movements, or means for adjusting the fulcrum to accomplish both of these results.

lin addition to the features of invention above referred to, the present invention also consists 'in certain devices, arrangements, and combinations of parts hereinafter dcscribed and claimed, the Iadvantages of which v ill be obvious to those skilled in the art.

The various features of my invention will clearly understood from the accompanyin,"r drawings, in which-- Figure l is a view in side elevation of n leather punching machine embodying the sume in their preferred form; Fig. 2 is a view in front e ovation of the machine illustrated in Fig. 1; Fig. :l is u view in rear elethe driving shaft und the bracket in which the shaft is join'nuled being shown in section; Fig. 4 is a sectional plan View of the rear portion of the machine illustrating'more particularly the construction and arrangement of theI mechanism for actuating the feed wheel; Fi r. 5 is u detail view partially in section i lustrnting thn construction nml arrangement of the parts iu proximity to th(` punch, and Fie'. C is a sectional plan view of Vthe parts illiistruted in Figa.

The frame of the machine consists ote a device, and a n im pu rtcd to m., di:

base portion 1 and an overhanging head portion 2. Upon thel hase portion l'a circular work supporting plate 3 is secured. The

unch is indicated at 4 and is secured to thc 5 ower end of n punch-stock 5 mounted to i reciprocate verticnllv in bearings in the head 2. A collar (l is adjustably secured to the Unch-stock between its upper and lower Eearin's in the manner illustrated and dcscribe( in my prior latent No.

The rear end of the shaft 8 is rovidcd .with an ami t) which is connected y means of a rod l0 to a strap surrounding an eccentric 11 upon the main driving shaft l2 which is mounted in beariu'gs in a bracket 13 secured to the frame of the machine. Thron h the connections ahora described the roc shaft 8 ia lactuated from thc main driving shaft and vertical reciprocating movements are im )arted to the punchstock and to the punch A hand are loosely (Nth-i226, This collar is prowheel and a series of belt wheels mounted upon the driving shaft 12 and are connected thereto by means of a clutch which is controlled by a bent lever '14 pivoted upon the bracket 13. The verti cal arm of the lever 14 is provided at its upper end with a pro'ection which enA ages a pro' tion on one o the clutch inem airs,

u the arrangement being auch that when these mjections are in engagement the rclt. pul- Ti; are disconnected from the driving shaft.

projection on the vertical arm of tht.`

lever 14 is normally held in the path of 4Q movement of the projection on thc clutch member. by means of a spring-plasmid pin 15 boerin against the vertical arm of the lever. Tie horizontal arm of the lever 14 1s engaged by n pin bearing upon one end of a .lever 16 pivoted upon the basa of the machine, the other end of the lever ltl le mpg connected by means of a chain 17 to a trcadle arid the construction being such that when the treadle is depressed by the operavtor the lever 14 is actuated to release the clutch and allow the belt pullc a to lie connected to the drivin shaft. T ie projection on the. clutch mem ier is so arrnn l that the hclt pulleys are disconnected rom thc a5 driving shaft when the punch stock is in its raised lposiition, the machine being stopped witi the punch raised frointhe work whenever the operator removes his foot from the trcadlc.

The work is sup iorted upon the work support 3 and is feti intermittenti beneath thc punch h v means of a feed wiecl to bc hereinafter referred to. In order to hold the work down upon the feed wheel and in 05 position during the operation ottthe punch a presser foot i9 i provided which, as illustrated, consists of a fluido-conical whccl :arranged so that its conical airfare contacts with the work aliore the fecd whccl, 'llhc presser foot is 'onrnalcd upon thc lower end of a rod l!l,t le axis upon which it turns heinkr at nn :ingle to the surface of the work support IL so that the n'csscr foot xtcnds licncuth the punch slot-it and contacts willi thc work in clo-c proxin|it \l to thc punch. 'l`hc rod l!) is mounted to move vertically in lxnrings in thc hcad 2. thc uppcr hearing`V con istin; `r of n .sleeve 20, through which the rod lil pass-cs, pivoted lietween carsI projectingr from the upper hearing for the punch-stmk. and the lower bearing consisting of a slot in a pro'cction from the lower hoax-ing for thc punch-stock through which a squared portion of the rod passes and in which the squared portion of the rod can have a lateral movement toward and from thc punch-stock. When therod lil is in its lowest. position with the presser toot in coutact with the work, the lower end of the rod It) is held pressed toward thc punchstock hy mean4 of a leaf spring ".51 which hears against the'squared portion of the rod. Near its lower end the rod lt) is provided with a rojection 22 provided with an inclined surfiioe which, as the rod itt is raised, contacts with the lower hearing7 for the rod and swings the lower end of the rod latcrallv, so as to remove thc priester foot from liencnth the punch-stmk. this Swinginr movement of the'J'Od l!) is permitted )y the. pivotallv mounted hearing 0 for the upper end of thc rofl. The lateral movement which is imparted to the prei-wr foot as it is raised allows thc pre-scr foot to lic located licncath the punci-Htock when in contact with the work nml in close proximity to the punch so that the wot-lk" is securely held during the punching oicration and the feedingr devices engage t e work as close as possible tf` the point at which it is opcratcd upon hy the punch. rthis is an mlvantagc in this class of inachines as thereby thc liability of thc work being dis )laced is reduced to a minimum, and slnalller variations in the length of the feedingy movement arc required i-n oder to canse tln` ixirforations to hc spaced canal distances apart when the curvature oif thc cd :e of thc work varies. 'lhc presser foot. is iicld vieldingly in contact with the work h v means of n spring Q3 coiled arnaud the rod 19 and interposed lictwccn thc upper hearing for thc rod and a collar .24 secured to the rod. rl'he prcsscr foot is raised. when desired. hy means of a hand lcvcr .35 pivotcd to the head of thc machine and connected at its forward cud li'v means of a link Qt to thc rod ltl. A spring catch *2 is arranged to engage the lever Q5 and hold the presser foot in its raised position.

This plunger is provided with u roll whieh beurs ligninst n clim 50 on the muiu driving lihnft und the roll is inuintnined in eontuet with the enni hy lnenns ot n spring 51 coiled around the rod und 115 inlerpiwed hetween one of the hearings for the rod :ind n shoulder on tlu` rod. 'lhrough this plunger the l'ever 47 iu oweillnted from the drivilrer Hlulft. "'lhe other end of the lever 47 is connected by nienns of n link 52 120 to one iii-in of li lever 58 pivotnlly mounted upon the frulne of the nniehine. The lever 53 is provided with unother urni on the Sallie side of its pivot which is connected by means of n link 54 to the stru of u roller clutch L25 device lliounted u ion tile renr end of the .Qhnft 43. This cuteh device is of wellkllowli construction nlld will he rendily uliderstood from the illustration eontuined in Fig. 3 without further description7 it being 118'@ merely sutlicient to state thai t'ne shaft 43 i: clutched to the strap during the movement of the strap in one direction` and is unclutched from thi.` stra) during its movement in the opposite iiirection, the action being similar to that of a piiwl nnd ratchet mechanism.

It will be evident that the extent ot' the individual feeding movements imparted to the feed wheel will depend upon the iosition of the fulcrum of the lever l? and if tlie fulcruin is adjusted the length of the individual feeding movements \\ill be correspondingly varied. In order to adjust the normal length of the individual feeding7 movements the block tti is adjustably nimmted upon a rod 55, the block being provided with a split. collar which embraces the rod and being clamped to the rod by a clamping screw 56.

ln order to vary the length of the individual feeding movements during the opertion of the machine, it, is necessary, in the construction illustrated, to move the fulci'iiin of thel lever At7 nml to accomplish this rcrsult the rod 55 to which thc bloclt 49 is: secured is mounted iii and forms ii part of a traine 57 which extends transversely across the machine and is pivotally mounted on the bracket 13 by incaiis of pivot pins 58 which are so arranged as to iillow the frame 57 to swing in a horizontal ilane. The frame 57 ig provided with a downwardly projected arin 5t) to which is bolted the rear end of a rod (it) which extends tzhrough the base of the inaehinc to a position in which it can he conveniently actuated by the operator. lli' incuria' ol' thiI rod the. operator is enabled t0 swing the frame. 5T in either direction nml thereby nieve the blocks 48 and fi!) no as to adjust. the fulcrnm of the lever 47 during; the operation of the machine. 'lho extent. of the movements which may 'oc imparted to the frame 57 by the operator ia limited by adjustable stops t'il screwing through irojections on the base of the iiiachine and arranged on opposite sides of an arm @l2 prooi-ting from the franic 57. 'llie fraine`57 is noraiallv held in its central position by means oi spring-pressed plimgcra 6ft mounted in hearings in the have of the machine and arranged upon opposite 4widen of the arm 55) of the traine 57. lliich ot' these, plungers is `vnri'oiindcd by a coiled #tiring t'it interposed between a shoulder on block t ic plunger and a reiiiovahle bearin with (15 and is provided at its outer ein atop nuta4 titi.
