Specification of Letters Patent.

Application e. llbecember, 190s, serial No. ile.

To all whom may concern Be it known that I, ilnnnnnion M. FUR- neu, e citizen of the United States, residing et Revere, in the county of Suffolk und Commonwealth of Massachusetts, have invented certain Improvements in Splitting-Maichines, of which 'the following description, in connection with the accompanying drewings, is e specification, like reference cheracters on the drawings indicating like parts in the several figures.

rhis invention relates to machines for splitting stock end is shown es embodied in e machine which is splitting," u died outl piece ofl leather.

' One. object ci this invention is the provision, in a machine of the shove class, of means for cziusing the knife to split from the stock n sheet or shaving, or a flap, or' uniform thickness. in the machine illustrated vthis result is obtained by yproviding a gage to hear upon thesurface of the stoel: in advance of the point at which it is engoged by the knife, the distance between the lower or effective edge of seid gage and the plane of the cutting` edge of tie knife remaining constant and eorrespondingto the thickness of the flap or of the piece splitoi. Preferably also, means may be provided to adjust the machine so as to change the distance between the effective edges of the gage and knife and consequently to vary the thickness of the flap or the piece split olif.

Another' object of this invention is. the provision of ineens for .causing a flap/Which has heen produced on the stock to he removed therefrom when desired. In one embodiment of the invention this result may he accomplished by providing ineens which hccomes operative when the knife has ut for a` certain distance to automatically ce i/se seid knife tolesve the stock, thereby splitting from the stock e piece of uniform thickness which may have one edge beveled, To produce this bevel the means above referred to be adapted to chen e automatically thedistence between the eigfective edges of the gege und knife, thereby causing-said knife to out :i piecei'whichis progressively thinner from the time et which seid means becomes 'operative until. the knife leaves the stock. In another embodiment of this invention the means for causing the lisp which hesheen produced on the steckte be removed therefrom' may taire the forni-'oi' e especially adapted 4for second knife, end this knife mei] c 1 iently he caused te operate on the stroke o" the ommen lrnii'e carrying her. Preferably this second imite is edil able on its support so that the :ingle bevel produced on one edge of the sh may he varied within wide limits, tn limits being wide enough to eiiow the to operate in e direction et right the plane of the surface oi the desired. it is advantageous to provide ineens t* varying the point et which this isn lr ing means becomes operative. i may he any suitable one, n tinted embodiments ci. the :inv seperate forms are shownwl ,i the form the member which. depressesthe is a wiper or cam of any given so io, tached to its support theiJ other Wipers o any desired contour may he substituted., the second forni the member which depres the gege is adjustable se es to ve?" point et which seid gege becomes ooe-rs ln the third form the member which i the second. knifeis edjustshie es is also abutment which cerises seid knife to enge the stock. Attention is directed to the feet that, although these various means for csi sing' the ifiep to he removed from the steclf and forvarying the "point et which means becomes operative ere quite distinct in their forni and :manner of operation, nevertheless they serve to ,accomplish tical purposes and that obviously other ioif'rns may he substituted without deperti.-g the scope of this invention.

lin machines or the class described., it advantageous to provide ineens for det mining the extent of the split produced n .the stock. This may be eccomplis ed providing means for varying the et' the effective stroke of sind lni'ie; end seid means mey be nf any suitable iorr Y that shown in the illustrated embodiment being adapted to very the initiel position ci? the knife. ieieretofore it hes heencustomery te provide en adjustable stop or guide against which to piece the edge oi the'steei, th position of. the guide determining; the tent of the cut. However, owing, among other things, to 'the smell e'veiirihie between the knife andnthe stock support seid guides have proved unsetisfectorjf.

from

seeznssdventegeous, therefore, to provide means whereby some associated part of the lknife carriage may serve the purpose oil a guide :t'or placing the stock. This may be accomplished by providing means for causin'g the knife carriage to move in a closed path together withj'mcans for varying the in tial positionoi' said carriage and thereby the position at which it 'comes to rest. 1n order to cause the knife carriage to move in a closed path and to allow the initial position of said carriage to be varied at will, said carriage may be operated from a rotating member by a link or other .rigid connecting means, the end remote from said carriage being adjustable in a segmental path struck about the axis ot rotation of said rotatingl member, the machine being provided further with means for causing the rotating member to come to rest always at a fixed point. By this arrangement the knife carriage or some associated part thereoi" may sci-fe as a stop against which the edge of the stock may be held prcpaatory to the splitting operation. the kni te carrying member or one oit its associated parts thus ing as an adjustable guide which can be set so as to produce in the stock a` slit, or to remove from said srock a shaving, as the case may be. of any desired length.

Another object ot my invention relates to the-provision of means tor giving a curved or 'fancy contouz` to one edge ot the shaving which is removed from the stock. By this means one edge of the snaving may be given any sort of curved outline or may be pinked in any design desired. ln one embodiment'v this may be. accomplished b v providing the knife vvhich slits the stock With the desired outline.v in which case the gage will be provided with -a corresponding outline. In another embodiment in which a second knife is used the edge of said second Y, knife Will be given the contour desired.

These and other 'features of the invention including certain details oli construction and combination of parts -will be explained in connection iv ith the 'following (..escription oi a machine and will be pointed out in the claims.

As illustrating concrete examples of the uses to which the invention may be put the marhiiic may be used to form a iap extend-A ing from the bac'k of the heel ot' a sole to the shank so that said flap may be bent down in front of the breast of a Wooden heel such as is used on certain varieties of slippers and thereby constitute a portion of the leather covering of the heel. OI' the machine may be used to remove from stock a portion which is not. needed in the use to be made of the stock, and which may be. capable ot other use. For instanccWit may be used to cut a shaving from the I:grain side of the heel of a died out innersole, and after-the shoe has been assembled the shaving. which may ha ve 'adjustable aliases been rolled and died out in the meantime, may, if desired, be cemented back in place to cover the clenched ends of the nails pass through the heel of the sole, thus saving the expense of providing a separate lining or innersole to cover sail nails. Again, in providing shoes with cushion heels, the machine may be used to slit the heel of the innersole prei'iaratory to inserting the cushion. Various other uses for the device will occur to' those familiar with the art.

Referring to the accompanying drawings, Figure 1 is a perspective view of a machine embodying my invention; Fig. 2 is a longitudinal section thereof; Fig is a sectional view ot a portion of the machine showing the presser gage in. operative position, the knife having just removed a shaving from the stock; Fig. 4t is a sectional view in every respect similar to Fig. 3 except that. the presser gage is shown in inoperative posh tion; Fig. 5 is a perspective view of a modified machine; Fig. 6 is a broken longtitulinal section thereof; Fig. 7 is a detail showing a knife and bed which are suitable for use With either of the machines shown; and Fig. S is a detail of another modiiieation.

Referring to Figs. 1 to l the machine comprises a base 2 having means such as bolt holes 3 by which to tasten it to a suitable support, and provided with Ways si for a carriage 6 which may be reeiprocated on said Ways by means of a connecting rod ."i which in turn may be operated bvl mecha.- nism presently to be described. On base 2 is mounted a Work bed or support 14. in the embodiment illustrated in Figs. 1 to 4. a vcoringated plate 15 forms the upper partot 'this support or bed and is attached thereto by screws 19 so that it may be reversed end for end when desired, for a purpose hereinafter explained. .it should be understood, h oivever, that the plate might be made an integral part oi the support and that instead of corrugations a plurality of pins or` other equivalent holding means might be provided, such a construction being shown at 114 in Fig. 5. The bed 14 is supported over base 2 by springs 16, adjustable stops 18 being provided to limit the upward movement, but permitting said bed to yield against the tension of said springs. On earriage 6 is mounted the knife 20 in any approved nianner, but preferably se as to be to compensate for Wear. For instance, the knife may oe mounted on the carriage 6 by means of bolts headed on their under ends so as to exert an upward pull on the knife and With their upper threaded ends passing through slots -17 and carrying nuts 27. ln bearings 29 in the carriage and in advance of the knife is mounted a Work clamping bar or gage 24 having trunnions or pivots 22 fitting in s a-id bearings 29. The function of said gage 1s to engage the stock duced, the bed 14- niay be provided with a any desired position in the segmental chani, nel by means of the nut 54. The segmental channel is struck about the axis of rotation of the plate 5l as a center, and consequently the carriage is caused to move in a fixed closed path regardless of the point at which motion begins. And if the plate 5l is caused always to start from and stop at one fixed position, the carriage 6 Will be caused similarly to start from-and stop at any desired position with regard to the bed il merely by changingl the adjustment of `the pin 53. Accordingly means are pro 'vided for causing the desired movement of the plaie 5l, said means comprising' in the illustrated torni a plurality of parts which will now be described.

The plate 5l has a spindle 59 which is mounted in a bearing 61; about the upper part oi this bearing is mounted a rotatable sleeve G3 carrying a gear wheel (55, which is rotated by a Worm G7 on a shaft G9, which carries fast and loose pulleys 7l and 7 3. In the upper part of the sleeve G3 are formed a series of notches 75 which are adapted to receive a latch 77 l'iivoted in a slot in the plate 5l and continually acted upon by a spring 79 which tendsto press said latch into position to be received by one of the notches 7 With the construction thus tar described, it the sleeve G3 were rotated the latch 77 'would be forced into one of the notches 75, and the plate 5l would rotate continuously. In order to control the rotation of plate 5l a. bell crank lever Sl having an extension S23 to which is attached a latch raising-member S5 is mounted on a rock shaft 87. This bell. crank .eve is held in the position shown in full lines-in which posi# tion the latch 77 is raised and the table 5l at rest-#byr a spring 89, and is moved to the position shown in dotted lines by depr ssingl the treadle 91, in` which position thellatch 77 is forced by the spring` 79 into one of the notches 75 in the rotating sleeve 63. In or der to insure the stoppage of the plate 5l at exactly the same position always, the bell crank lever Sl has a second extension to which is attached a. bloeit 92 having a slot 93 with which a pin 9i, fast to the plate, engagesY ne'wall of the slot is beveled as at 95, and the momentum of the plate causes the pin to ride up the bevel thus depressing the block slightly until the 4pin arrives' opposite the slot when the spring;` 89 causes the two to engage, thereby locking the plate 5l against movement and Causingr it to come to rest always in the same position.

ln order to t'acilitate the setting` of the carriage at the` desired initial position so that a eut ot the desiredlengtl'x may be proscale 9G. And tlxislsca-le is also useful in case a. high degree of accuracy is not repressed.

quired and the maeliineis rim continuously.

'1n such case the operator determines the length of the cut by placing the edge of the .stock in proper position on the scale.

The operation of theldevice is as follows: By means of the adjustable pivot pin and its associated parte the eye 57 of the connecting` rod 5 is fixed at any desired position on the segmental channel 5%. This determines the initial position of the ear I riage 6 and. hence the length et' the eut which will be produced in the Stoch". The stoel( is then laid on vthe bod with edge against the gage and the treadie This allows the spring 7S press the latch 77, which is engaged ne of the notches of the sleeve (3B,v it being understood that this sleeve is constantly ro tated Iwhile the machine is being used. The

treadle 91 then. released to allow the spring; SS) to return the bell Granit lever 8l to its initial position The plate. 5l, being; thus connected with the sleeve 63, revolves in the direction of the arrou1 in Fig. l. This causes the carriage 6 first to accomplie. its cutting stroke then to Withdraw to its elil treme opposite position, 'thereby uncovering the stock7 and then to return to its initial position. Just before the carriage reaches this position the member raises the latch thereby disconnecting the plate 5l from the sleeve 63, and then thepin 9i rides up the bevel 95 and rivages the slot 93. At this instant the carriage 6 cornes to rest exactly in its adjusted position and ready to make another out of exactly the saine length as the first one.

l Then it is desired te cut a shaving,` from the stoel: the*4 p1 AVeser f5() is as shown in Fig. so that, as the connecting rod. 5 moves in its path, the extension l5 will Cause the gage presser 30 to describe the are circle and 'in doing so tor-impe across the roller 49, thereby depressing the gage to cause the knife to leave the stock, and to out from said stock a' shaving of uniform thickness and having a beveled edge et the end last eut. 0n the other hand when it is desired merely to split or slit the stock the lli.

gage presser 30 is set as shown in Fig. e se that it'canno't Contact with the roller 49.

,lt will be noticed that the plete l5 of the bed is shown i one position in Fig. 3 and in reversed posieon .in Fig. 4. In Fig. 3 a shavingr 97 is bein;T removed from the flesh side of ay sole. n this ease the out is a light one and consequently it is unnecessary that a` large area` ofthe under side of the sole should be engaged by the corrugations of the plate. hfloreover, it is very. undesirable to disfigure the grain side any more than is necessary. and' therefore thei plate is so placed that the knife overruiis the corrua'atious Fig. -zhon the other hand, a'slit is beine :duced in the grain side of a sole.

ci i Here the out as a heavier one and hence 1t described as reciprocation, it should be understood that the motion might take place in any other suitable ath.
