To all whom it may concern:

Be it known that I, l'hinmrr E. JonNson, a citizen of the United States, residing at Beverly, in the county ot Essex and State of illassaeluisetts, have invented certain new and useful improvements in tiolelitting hlaehines; and 1 do hereby deelare the following to he a lull, clear, and evart drserip tlor. of the invention, rile-h as will enable others skilled in the art to whieh it appertains to make and use the same.

Thi invention relates to sole fitting n11:- rhines and more particularly to channel' 1 nlaehines whieh are used to channel, groove, shoulder or otherwise operate on the margin of a sole hlank to prepare it for attachment to the other parts of a shoe.

The invention is particularly concerned with the machine known commercially as the Economy insole channeling marhine, and it aims to improve the feeding mechanism of this machine with a View pa'rtieir larly to reducing the skill and rare re quired ot the operator; to devise a more salisfm'torr uieehanism I'or registering o; indioating the quantity of work done on the mat-hint; to improve the lip -"5!ttl111 or slash merhanisms often used in these machines; and generally to improve the eonstrnctlon and operation of machines of this type. The genenal construction of the machine above designated is shown in the Letters Patent oi the'Unit'ed States to vVil liain t. lhleyer, No. M4,?73, granted Febru err 21, 191.1. \Nhile the present invention is directed partioularly to the improvement of this marhine, those skilled in the art will recognise thatlthe various features of the invention are also applieahleto other niachines for performing analogous operations.

To the areemplishnient of these ohjeets and such others as may he hereinafter described, the invention resides in certain combinations and arrangements of parts, the emistrmttion and functions of whieh will be described hereinafter With the aid of the accompanying drawings. whieh show the preferred embodiment of the iuvmition.

The machine comprises a channeling lini'te and an edge slitting knife 4, which rat and turn upthe usual flaps or lips of a Welt insole; a hammer t' which sets these lips in their upturned position; a work supporting table 8 on which the sole is mounted while it is being ehanneled; a presser foot in which hears on the sole and presses it against the tahle H adjarent to the point of operation of the knives 2 and 4; and a l'Our-motirm feed. plate 12 which engages the upper are of the sole and Feeds it over the table 8 against the drag knives 2 and 4.

The knives 2 and l, the hammer (3, the tahle 8. and the presser foot 11) are all sup ported and operated suhstantiall, as shown in said Meyer patent, and re ereuee should he made to this patent for a detailed de svription thereof. For the purposes of the present invention it is sutlieient to state that the work supporting tahle is mounted for vertical moven'ient relatively to the (channoting, tools to permitthe insertion or reinovai of a sole between it and the tools.

a hove iiulieoted. the feed plate 12 is given a 'lewlinn' movement that advuuees the sole from right to left. as the parts seen in l ie. l. and carries it past the tools 2 and l. his motion is lhe same as that imparted to the eolrespfiilll llgj feed plate of the maeliine shown in said Meyer potent; hut a. now] lneelu i sn is provided liy this inveir i on l'or pro ilu-ilnir ihis movement. Further more in the snaehine of' sold patent the feeding movinani s lixed or unilorn'i at all times.

It will no readily understood by loose sk l-e l in the art that it is sometimes desiral-le to reduce the length of stroke of the veiling device as. for instance, when elmnneling: around the more sharply curved portions ol the margin oi an insole. For example. it is diiiieult to make the. turn at a sharp for if the w rk is lielnfl advaneed at the minimum speed Whieh can he used successfully along the straighter portions of eiirresponding seat l'ornied lor it in the clamping memla-rs. This rod is guided in the lower arm oi a. yohe in) and in a sleeve 2i \vhieh slides l'reely through the upper arm ol the yoke. A spring- JH is seated at its opposite ends on two collars Formed, respeetively on the rod 2i and the. sleeve 26. The upper end oi the rod 34 extends loosely through a sleeve till. nhieh is positioned lintween a. pair of nuts 30 on the rod A and zinotlier pair of nuts 31 on the sleeve 26, and

lh sleeve is pivotally moulded on lhe li'ee rr l oi an min .31.. lined 1 rook ll. :1!

ilml is mounted in uitable ileariw niiper part ol' the n'm 'hine frame. dillUllill 'ir? 2&5 :dso lived to the m lt shaft ll, and preferalllv parallel to the arm 22 1-, is pin otallv eonneeted to the upper end ol :1 depending om follower 343 that ineloses a cam 13% (dotted lines Fig. 1) mounted fast on the main shaft il of the machine. It is ohvious that as this emu tollower 36 is re eiproeated up and down lay the movement of the cam 38. it Will produce an up and down movement of the sleeve 29. The upvrard :i'unement of this sleeve is transmitted ihrougjh the nuts and rod 292 to the feed plate iii. thus lifting: it positively away from ine work: While the downward movement of the Sleeve 25 is transmitted v'ieldingly to h plate throur h die nuts ii. sleeve 2 spring 2 and w l 34-.

The, horizontal reciprocating, movement given to the feed plate 12 is produeed by an eeeentrie pin 4-2, projecting from the end of the shalt 40. and rotatably mounted in an eoeentrie hloek -43 whieh slides in a slot iormed in the yoke 25. The righthand end oi" this slot (Fig. 1) is closed by a plate 4:4 and a spring 4- (Fig. 2) located between the hlook 43 and the plate 44 tends to maintain this lllOPlC at the opposite end of the slot. h'dinarily, however. the full horizontal eon ponent of the. eeeentrie movement of the pin 42 will he transmitted to the yoke 25. one stroke of course being transmitted direetly irv the engmgjenlenr of the l)l()('l{ 43 with one end of the slot in the yoke 25 and the opposite stroke being transmitted to the yoke through the spring: 4-5. The horizontal movement produced hy this eccentric pin 42 and the vertical movement produced by the eam 3 are timed to oileet the desired fourmotion feeding movement of the plate 12.

The shortening of the feeding movement ahove referred to, is produced by limiting misses the range of theinevement ef the yoke 25 which is transmitted to it through the spring 15. For this purpose astop screw 48 isadjustnbly mounted in the free-end of a an arm a9 (Fig. 1) which is pivoted on-the machine frame "and homely; is held in a raised position by means of a spring 51); but the arm may he depressedby operating a foot'treadle (not shown). "the connection 10 between the arm 4:9 and foot treadle comprises a rod, or bent wire, 51 (dotted lines Fig. 3) connecting the free end-ofthe arm to the forward end of a lever 151 pivoted on the frame and depending from the lever 1 51 is a cord or chain attached to the treadle. When the lever 49 is swung downwardly, the end of the stop screw as is moved into the path of movement of a "hardened plate 52 carried by the yoke flo, and-the engagenient of this plate with'the stop-screw stops'the movement of the yoke beforeit has completed its backward stroke. Inasmuchas this stroke is transmitted to theyoke through the spring 45, and sincethe eoeentricpinifl 25 moves in a'fixed path, the part ofthe movement of the eceentricpinwhich otherwise wouldcompletethe stroke of the yoke, is taken up in compressing'the spring '45. As soon as the treadler.is released the spring 3-0 withdraws the stop ail-from the path of movement ofthe plate 52 (a pin-fia in the frame limiting this 'movement of the stop) and'the yoke is-themfree to make its full horizontal stroke. The ability of theworkman to change the length of-the'stroke of the feed plate 12 quickly whenever desired, is a great convenience in guiding any character of work having diriferentangles.

The presser "foot 10' asclearly-shown in 40 Figs. 4 and -7 is slotted to straddle the forward end of the teed plate 1 The knives 2 and'e he immediately behind the presser foot 10 so that one end of the feedpl ate passes betweenthese knives on its forward as stroke and exerts itsfeeding eifort on the sole at points very close to E the point at which the knives resist the advancing movement at the work. The part of the presser foot that bears ontheex'treme marginal porso "tion of the sole S see Fig. 4) lies just in front of the edge gage bii which serves to guide the sole relatively tothe tools while'the channeling operation is being performed. This edge gage is moved in and out, as the 55 channeling operation progresses around the margin of the insole, by meansof a mecha nism exactly like that disclosed in the Meyer patent above designated. \Vhen the edge gage is moved toward the tools there is sometimes a. tendency for the extreme marginalportion ofthe insole to curl up as it is fed forward against the'edge gage, an thusto interfere withthe proper guiding of the solerelatively'to the knives 2 and 4. In fis'order to overcome this diifieulty the feed plate 12 lsprovidedwith alateral extension 57 (see Figsn l and 8) having a sole engaging face lying in the same plane as the corresponding face ofthe feeding device. This extension bears on the extreme marginal portionof the sole just in front of the edge gage 56, andservesto press the margin of the sole'firmly' against the sole supporting face of'thetable 8. Since a part of the presser foot 10 also bears on the extreme margin of the sole just behind the edge gage 56, this part of the presser foot cooperates with the extension 57 to hold that part of an insole which at any instant bears against the edge gage 56, flat against the table 8 and thus 5 prevents any objectionable curling up of the sole.

In the machine illustrated the edge gage 56 is-shown as provided with a chamfering knife which is described and claimed in my copending application, 'Ser. No. 83,053, filed March 2), 1916, patented December 5, 1916, No. 1307,4119 but this attachment may or may not be used, as desired.

It is often desirable to cut or slash transg versely one or both of the lips or flaps formed by the knives 2 and 4 for the purpose offac-ilitating the turning of these .lips upwardly. To this end a knife 60 (see Figs. 1 and 7) is mounted close beside the presser foot 10 where the stock is held firmly to the table, preferably, although not necessarily, between this device and the knives 2 and 4, so that it will cut into or slash the stock just before the knives 2 and l'form the lips. In 190 other words, this knife operates in advance of the lip forming tool to make transverse slashes in that portion of the stock lying in the path that the tool will take in the sole, so that when the lip is formed it will be provided with transverse slashes in the desired 1113311161. The knife shown in dotted lines (Fig. 7) is shaped to slash both the lips formed by the knives 2 and 4, but it does not cut or slash the between substance. ()bvi- 1 9 ously, however, the knife may be shaped to out only one of the lips if desired. By lo eating the knife close beside the presser foot the depth of its cut can be acci-iratciy determined, since the presser foot holds the sol firmly against the table 8 and the knife (ill cuts to a fixed point above the table. The depth of out should be not greater than the thickness of the stock out by the tool so as not to weaken the body of the insole.

The knife 60 is secured in a holder (31 by a clamping bolt 62, the holder being groove-i. as shown in Fig. 4;, and the knife being slotted as shown in Fig. 7, to permit a vertical adjustment of the knife relatively to its holder. The holder consists of a bell crank lever fulcrumed at (33 and having an up right arm 64. A spring connected at one end to the machine frame and at its opposite end to theholder 61, maintains the knife 61) normally in a raised position where it is inoperative to cut the sole.

power driven mechanism is provided to give the knife its cutting movement, and this mechanism is controlled by the workman through the hand lever (36 by which the adjusting movement of the edge gage 56 is elicctcd. The lillll tf operating mechanism comprises an arm (38, pivoted to the free end of the bell crank lever arm and project ing through a slot formed in the machine frame so that it can be swung either into or out of position to be engaged by the head of a stud that is inserted in the front face of the can] disk 71, found also in said hie-yer patent, mounted fast on the shaft 40. The stud ill acts as a tappet cam for operating the knilc b) as will now be described. \Vhen the arm 68 is in the position in which it appears in full lines in Fig. 7, it is completely out of the path of movement of the pin 70, and the slashing mechanism, therefore, is inoperative at this time; but when this arm is swung up into the position in which it is shown in dotted lines in Fig. 7, it lies in. the path of the cam 70, and will he struck by this cam once in each rotation of the shaft ll). Each blow thus delivered to the arm (35 swings the knife holder (31 downward about its pivot (53, causing it to quickly approach and form a slash in that portion of the margin of the sole which is below it. The cutting operation is instantaneous as the knife, of course. is immediately withdrawn] from the stock by the spring 65.

The controlling mechanism for causing an operation of the knife 60 includes a lever 72 pivoted on a bolt 73 (see l ig. ti) and having a forked end that embraces the arm 0s and serves to swing this arm either into or out of the path of nwvenient of the cam 70. The opposite end of the lever i2 is pivoted to the upper end of a rod 7% which is mounted to slide vertically through a stationary guide T5 (see Fig. 5) on the machine frame, and through a bracket 76 which is movable with the work table 8 relatively to the rod Ti and forms part of the support for the edge gage adjusting mechanism. A spring is encircling the rod T4, and bearing against a collar 79 secured thereto, tends to raise the rod and thus to swing the lever 72 into such a position that it will hold the arm (38 in its inoperative position in which it appears in full line in Fig. 7. For the purpose ol' depressing the rod T4 against the iniillelfice ot the spring T8. a curved lever 80 (Figs. and 5) connected with,the rod Til through a clutch so that it is free to move up and down with the bracket T6 relatively to the rod except when it is moved to throw the slashing mechanism into operation. As best shown in Fig. 5, this lever 80 is pivoted at 81 in a head 82, having an integral sleeve 83 surroiulding the rod 74 extending upwardly an aperture formed for it in the bracket 76. A spring 84 encircling this sleeve hears at one end on a collar 85, which is clamped to the Sleeve, and at its other end on the upper side of the bracket in so that it tends to maintain the head 82 in contact with the lower side of the bracket. When the lever 80 is depressed, it first swings about its pivot Si in a clockwise direction (as seen in Fig. 5), at which time a sharp edge 57 formed on the upper end of the lever bites into the side of the rod 7% and causes the rod thereafter to move downward with the lever. A suitably connected spring 88 tends to swing the lever 50 about its pivot M1 in a direction to hold the lever free from the rod.

As clearly explained in the Meyer patent, above designated, the lever 66 must be swung about the axis of the disk 67 in order to effect an adjusting movement of the edge gage 56. A latching mechanism, however, is provided to hold the lever 66 in any adjusted position, and before this lever can be swung to change the adjustment of the edge gage, it must be depressed to unlatch it, such of a spring 69 (see Fig. l). A change in the adjustment of the edge gage is required as the channeling operation progresses along the junction of therefrom through or both 01' the lips formed loy the tools 2 the control of the edge gage adjusting mechanism so that a single lever will control both the edge gage and also the slashing mechanism. It is for this reason that the lever 8!) lies just under the lever 66, and that it is curved so as to extend parallel to the path of the swinging movement of the lever 36. The parts are so designed that when the lever 66 is depressed to unlatch it, preparatory to changing the adjustment of the edge gage, it may engage the lever 80 not move it down grip the rod 74 mechanism. A further depression of the lever 66, however, will initiate the operation of the slashing mechanism. This mechanism will then continue to operate until the lever 66 again releases the lever 80 to the influence of the spring 88. The downward movement of the lever 66 operates (as will he clear from Fig. 5) first, to swing the lever 80 about its pivot 81 and cause it to grip the rod 74, and thereafter, as it is moved farther downward, to carry the rod 74 down with it, thus tipping the lever 72 far enough to move the arm 68 into the path of fatetion of the cam 70 with the result already described. As soon as the pressure thus applied'to the lever 80 is removed, thespring 88 swin Is: the lever in a direction to release the rod :4, whereupon the spring 78 raises this red thus swingingthe arm (38 again out of: the path of movementof the cam and stopping the operation of the slashing knife. The springfietalsovreturns the headtSQ, and with it the lever. 80, to their; normal positions. A small pin 90 proiecting. from the head 82 through an aperture in the bracket 76 guides the head in its up and down movements.- i

it is obvious that if it. is desired to slash the lip'ol' the insole at some period when it is not desired to change the adjustment of the edge gagehfi as for instance when channeling around the too, it is merely necessary to depresstheedgn gage operating lever 66. Thisnovel controlling. mechanism, however, is highly advantageous in enabling the operative to control, through a single lever, both the adjustment of the edge gage and also the operation of the slashing knife; and to operate either one of these parts, or both of them simultaneously, as may be desired.

The slashing mechanism of course is used chiefly when the machine is operating along the more sharply curved margin of a sole near the junction of the-shank and forepart, and around the toe. At other times it is preferable to avoid slashing the lip; and the number of slashes required for any curve depend, of course; on the radius and length of the curve; The controlling mechanism provided by this invention enables the workman to throw the slashing mechanism into and out of operation at Wlll and to make as few or many cuts in any. portion of the lip material as may. he desired- Machines of this c'haraeterordinarily are put out on airoyalty basis-and it is a common custom to measure this royalty by the number of revolutions that the machines make, iniproducinga pair of soles, an indicator being providedto register the turns or revolutions of the main shaft of the machine \Vhile. this praetice'is fairly accurate still acareless operator may. allow his machine to run idly,,thus indicating a larger of work! done: than actually has quantity been performed.., To obviate this disadvantageiteis the better practice to register the number of pairs of soles passed through the machine; The illustrated machine,

therefore, is eqaipped with a registeringg or indicating device which is operatedonly by a movement ot the work supporting table 8 of sutlieient extent to insert or removea sole. The indicator 92 maybe of any. suit able construction and may. be mounted in any convenient position on the machinebut is here shown as secured to the top of the machine frame at the right. The operating mechanism forthe: indicator consists of a modified hell crank lever 93 (see dotted lines Fig. 3) iulerumed at 91L inside the frame and having a hall end 95 engaging a slot formed in: the. vertically movable slide which onus the shank ol' the. table 8 and, there- 'i'ore, moves \vithi'it. This lever extends rein front to haclr of the machine and is pivotally connected at its rear end: to a long upright rod 96 that extends within the lirame and into the casing of the indicator; The upper end of this rod. is shaped to engage and actuate the toothedregistering mechanism operating wheel 97 with which indicators of this character usually are provided. A spring 98 (see Fig. (5) acts on the rod 90 to press it against the periphery of the whee-1.97.

As fully explained in. said hloyer patent the worlrsupporting table 8 is rigidly held in itsupper or operative position while the machine is channeling a sole, the tools that operate on the sole being supported to yield, as required, to variations in the thickness of the worlr. Only a relatively small downward movement of the table is actually necessary to permit the removal or introduee tion of the work, although a considerable movement is. ordinarily given to it for this purpose, Accordingly the parts 93 to 97 that operate the. indicator are arranged to transmit a registering movement to the indicator during the first part of the downward movement of the table 8, and a continuation of its downward movement. does not further affect the indicator". For this purpose the upper end of the rod 96 is so shaped that when it is in its lowered position. and the table 8 is raised. the end of the rod willlie just under the-edge of the nextrtooth with which it is to engage (see Fig. 6); and when the tabl is depressed even a fraction of an inch, the rod 96 Will he moved upward far enough to cause its end to engage said tooth and move the wheel 97 ahead one tooth. The rod, however. operates so nearly on a tangent to tile wheel 97 that. as soon as it has performed this operation the next succeeding toi'ith will force the rod 96 to the right in Fig.- 6 and out. of engagement with the tooth which it has just advanced. Thereafter the rod 96 will continue to move upwardly, in substantially. a straight line in response to a continued depression of the work table. Such a movement obviously will-not afi'ect the indicator. it being necessary for the rod to return again to its lower most position befor it can again transmit a. nioveniei-it to the indicator wheel. As shown in Fig. 6 sufficient teeth are provided on the indicator wheel-97 to provide for an operation of the registering mocha nism only at each second operation of the rod 96; that is. it registers pairs of soles. Suitable friction pawls or equivalent devices are, of course provided to prevent the accidental movement of the toothed Wheel 97. The indicator obviously may be designed to indicate the number of single soles operated upon instead of pairs of soles, as may be found convenient.
