' CUTTING- MACHINE.

Application filed ul 26, 1920, Serial No. 53 98,969. Renewed September 14 1923.

' This invention relates to machines for-cutting blanks particularly ing-out shoe part blanks other like material.

to machines of the type fordiefromf leather or Dieing-out machines as heretofore goonstructed have been regarded always as among the most dangerous of machines to operate and many operators have lost fingers and other parts of the hands through accidents due in some measure to. carelessness on the part of the individual concerned but .in greater degree to deficiencies and defects in the construction of this type of machine. 7

It is an object of the invention to provide a dieing-out machine which will furnish such safeguards for the operator that it may b regarded as practically fool-proof.

In one aspectthe invention comprises a die and a co-operating presser member which respect to each other while the work is being introduced and which must bev relatively shifted into operative position preliminary to .an operation of the machine and held in such position by one hand of the operator. while the other'hand is employed in actuating the starting lever. V

In another aspect the invention comprises a presser member which is normally out of operative position with respect to the die and which must he returned and held in operative position by one hand of the operator in order that the startlng means which is controlled by the movable presser member may be operated by the other hand of the operator.

In still another aspect the invention rei sides in a dieing-out machine having a relatively movable presser member and die n em her so constructed and arranged that the starting means of'thernachine is controllfid directly from one. of said members in such manner that a second operation of the machine cannot take place until the starting le' ver has been released and allowed to return to operative position.

An important feature of the invention resides in a magazine which is arranged: :iedly in alinement with the die to receive blanks therefrom and in means operating in such a manner as to space the blanks in the mega from sheet material and more zine from those the die so that the blanks .may be easily removed by the operator whilev ment being preferably such that the gage or pin projects into the plane of the cutting edge of the die from the Presser member upon which it is mountedh In the illustrative construction, the gage is part of a resser foot member which presses upon and holds the work in position on the die. e

Other features oftheinvention and other combinations of parts .will bedescribed in the specification and pointed outin the appended claims q l i In the'drawings: I "Fig. 1 is a front view of theillustrative i ach e; f f v Fig. 2 is a view in side elevation and partly in section of the machine shown inFig, 1'1; Fig. 3'is a detailed sectional'view showin g the gage mechanism; and

I In the illustrative machine there is shown a die 4 having its cutting edge facing-sip.- wardly toward a cutting block or presser member 6, means being provided fo-rca-u's ing relative movelnentofthe die and presser member for forcingsheet material upon the cutting edge of thedie; whereby blanks are cut and fo ced'into t e die.- Pre-terably the ie is statio ary nd has a magazine 18 a1 ranged in. rmament there it whi the press r member is reeip oe ble -o ard a d r m the die; Upon reference to the draw:v

machin ln ited ion part of the die 4, the slide being normallyheld in a rearward or inoperative position, thus uncovering the greater part of the die so that the work may be readily introduced into position for cutting operations. Means is provided for retaining the block in inoperative position, the said means in the construction shown comprising a spring 28 interposed betweena stud 30 at the rear end of the slide 24 and an abutment or shoulder provided adjacent the front surface of the presser member, the said abutment being preferably a screw threaded plug 32 which can be removed to permit of the removal and replacement of the spring 28. For moving the slide 24 forwardly into operative position there is provided a handle 34 fixedly attached or integral with the slide. It will be clear that the operator must hold the slide in operative position against the tension of the spring 28 and that upon release of the handle 34, the slide will be at once returned to rearward or inoperative position. From an inspection of Figure 1 it will be clear that a portion of the pre sser member 6 has its lower surface in the same plane with the work contactingsurface of the slide 24 and that this integral portion of the presser mem her 6 co-operates with the said surface on the slide to provide a pressure applying surface completely covering the die 4 and co-operating therewith to cut blanks from the sheet material. Mounted in the described pressure applying portion of the presser member 6 is a gage device which it will be clear, is always in a position directly over one end of the die so that the work may be accurately positioned with respect to the die preliminary to each cutting operation.

The gaging means referred to in the fore going description comprises in the illustrative machine a plunger 36 mounted for vertical reciprocation in a socket38 in the lower portion of the presser member and backed by a spring 40 for projecting the plunger to ward the die, means being provided for locking the plunger in retracted position from which it may be released at the will of the operator. Mounted in the body of the plung; er is a latch 42 which is projected by a spring 44 so that the end of the latch normally engages in a notch in the side of the socket 38 whereby the plunger is locked in retract-ed osition within its socket. For releasing the latch to permit the plunger 36 to be projected there is provided a tripping member in the form of a plunger 46 mounted in a socket 48 and pressed upon by a spring 50 which yields upon slight pressure upon the plunger 46 so that the latter may be moved,

of the cutting edge of the die. In order that the cam member 52 may returnto its initial position below the projecting end of the latch 42, the end 60 of the cam member 52 is made separate from the bodythereof and is pivoted to said body portion at 62 andis' held normally in extended relation to the body portion by means of a leaf spring 64..

The work is prepared for the operation of this machine by having perforations or jig holes made therein adjacent one end of each piece of work and in positioning the work with respect to the die it is first brought into engagement with the gage or jig pin by being threaded over the gage or jig pin 58 and then moved upwardly on the gage or jig pin until the tripping plunger 46 is operated to move the latch 42 out of its holding notch so that the plunger 36 may be projected to ward the die. By means of the gageor jig pin 58 one end of the piece of work is accurately positioned with respect to the die and this assists the operator in completing the positioning of the work with respect to the remainder of the die and the plunger 36 operates as a presser foot to hold the piece of work in its adjusted position. During the operation of the machine and upon descent of the presser member 6 the plunger36 is forced back into its holding socket and the latch 42 retainsit there while the presser member rises and moves to its upper position of rest. As the presser member rises the tripping plunger 46 also moves back to its normal position under the pressure ofthe spring 50 and themovable end 60 of the cam member 52 returns to the full line position shown in Figure 3, since the said end is so mounted as to wipe by the'end of the latch as above described. Hence. at the end of a pressure applying operation the gage or jig pin and its plunger are locked in their upward or retracted position. 7

In the illustrative construction the die 4 is mounted upon a supporting bed 66 which rests at its ends upon portions 68 of the machine frame. Mounted in-the portions 68 are rotatable members 70 having screw threaded portions 72 at their upper 'ends which engage blocks Tel, the arrangement being such members 7 6 comprising part of thema gin zine 8, the construction and arrangement being such that the cavity of the die, the opening through the bed 66, and the magazine are all in alinement with each other. Preferably the lower portion of the magazine is movable with respect to the remainder thereof so that the-capacity of the magazine may be varied according to the quantity of blanks which have been forced through the die at any given time. In the illustrative construction it is the bottom plate- 78 which constit-utes the movable portion of the magazine, the said bottom plate being slidable upwardly and downwardly within the sides of the magazine formed by the slats or, frame members 7 6. For supporting the bottom or bottom plate 78 there is provided meanswhichgin the construction. shownacomprises a cord 80 attached to the bottom plate and passing over pulleys 82-and 84: to a'weight orweighted member 86 to which the cord is attached, the said weight being'movable in a casing 88 liavinga spring 90 at its lower end to prevent unnecessary jarring when the weight is dropped upon release of the bottom plate 78 will be clear that the bottom plate 78will he held against theunder sideof the bed 66 when the magazine is empty and that as blanks are cut into the dieand forced down into the magazine, the said bottom plate will move downwardly progressively with the insertion of blanks into the magazine; Meansis preferably provided for holding the expansible portion of the magazine in the position to which it is moved as each blank is forced into the upper end of the die, thereby moving another blank into the magazine. In the construction shown, the bottom plate '78 carries a rod 92 which is fixedly attached to the bottom plate or form integral therewith, the said rod having onone surface a series of teeth 94 adapted to be engaged by a pawl 96 mounted on a shaft 98, a'spring 100 being mounted to operate on an arm 102 extending from the shaft 98 in such manner as to hold the pawl 96 constantly in engagement with the rack teeth'94a It will be clear that the pawl 96 by engagement with the teeth 94.- holds the bottom plate 78 against upward movement by the weight 86 and that each downward movement of the bottom plate is retained by means of said pawl. Cooperating with the rod 92 are other rods 101,

secured to the plate 78 and movable in guideafter emptying the magazine. It

ways 103, for supporting and guiding the plate 7 8; Extendingupwa-rdly from the arm 102 a rod 104 which'is pivoted at its upper end to a hand lever 106 pivotally mounted at 108 on the frame ofthe machine or on the bed '66. By means, of-the handle 106 the operator may release the pawl 96"from the rack teeth 9-1 and thus permitinovement of the bottom plate 7 8 upwardly to initial position asthe weight or weighted member86 descends, such movement of the bottom plate taking place after the;magazine has been emptied preliminary to another series-0f cutting operations.

. Thestarting and stopping means of the machine comprises, the illustrative construe tion, a clutch mechanism for operatively con necting the power pulley 110 to the shaft 1 8, the said mechanism consisting of a clutch member 112' fixedly secured to "the shaft 18 and pin members 114 mounted in the pulley 110 and movable endwise to engage in pockets in the clutch member 112, movement of the pins in the clutching direction being caused by sliding movement ofa sleeve 116 which is slidable axially of the shaft to insert and withdraw the ins'from said notches. Engaged'with the s eeve 116 is the forked end of a lever 120 which carries rolls engaged with a groove 122 on the sleeve member116. Preferably the lever 120 which is pivoted'to the; frame of the inac l'i ine at 12% has an arm 126- arranged substantially parallel with the adjacent surface of the machine frame wherein there is mounted a plunger 128 pressed upon by a spring 180 in a socket back oft-he plunger, the tension of the spring being s'ufiicient to actuate the lever 120 whereby the sleeve 116 which is, connected to the pins 114 causes engagement of the clutch membersor, in other words,"

the locking of the power pulley to the fixed clutch member 112. When the machine is at rest :the lever is held in clutch re leasing position by means of a cam meniliier 132 on the shaft 18 engaging with an extension of thearm 126 of lever 120, the said 8211-- tension comprising a plunger 134' slidably mounted in the arm 126 and held in project ed operative position by a spring 136 in a 1 socket in the lever arm 126. p The plunger 134 has arod extension 135 passing throughtlie spring 136 and'pivoted at its'lower' end to a rod 138 pivoted in turn at its lower-end to a conneetinglink 140. This latter link is provided preferably with a slot. 142which receives a stud 1M mounted in the machine frame, the link sliding on the stud and turning about the stud as a centeras will be hereinaf-ter more fully described. As shown, the 1 lower end of the-connecting link 1 10 is providedwith a hooker shoulder 146 designed to be engaged by a"corr.esponding hook or shoulder 148 on a vertically reciprocable rod which is retained in a socket in the machine frame by a pin 152 and is pressed upwardly to its upper limit'of movement by means of a spring 154. Extending laterally from the rod 150 is a pin 156 received in a slot in a lever 158 pivoted at 160 on the frame of the machine. It will be clear that downward movement of the lever 158 under pressure applied directly by the hand of the operator will result in withdrawing the projection 134 from contact with the cam member 132 on the main shaft whereupon the spring pressed plunger 128 will operate the lever 120 to force the pins 114 into the clutch member 112, thereby connecting the power pulley to the shaft. At the end of the revolution the cam member 132 will again engage,

the projection 134 which has been returned upwardly by the spring 136 and thus move the lever 120 to the right into the position shown in Figure 2, whereby the pins 114 are withdrawn from the clutch member 112 and hence the power pulley is unclutched from the shaft. For assisting in bringing the shaft to rest a brake band is used and the latter may engage the fixed clutch member 112.

Meansis preferably provided for insuring against a repetition of the pressure applying operation upon a single actuation of the starting lever 158 and, in the illustrative machine, this object is secured through a di rect control of the starting means by the presser member. As shown, the connecting link 140 has a forwardly projecting cam portion 162 along which there moves a projecting arm 164 of the presser member 6 so that upon downward movement of the latter the connecting link 140 is turned about the stud 144, which at that time is at the upper end of the slot 142, and caused to unlatch the shoulders 146 and 148, where upon the connecting link 140 and the attached parts above the same are moved upwardly by the action of the spring 136 so that the movable projection 184 is in position to be cammed by the member 132 on the main shaft to withdraw the clutch and free the power pulley from the shaft even though the operator continues to press upon'the starting lever 158. When the presser member 6 rises at the end of a pressure applying operation the connecting link 140 is returned to normal position by means of a springpressed plunger 166 which contacts constant- 1y with the lower end of the connecting link; Upon release of the starting lever 158 the rod 150 moves upwardly underthe action of the spring 154 and the hook end of said rod again engages over the shoulder 146 on I the connecting link 140, thus establishing an operative connection between the starting lever and the clutch members.

Means is also provided, for controlling the starting means from the laterally movable portion of the presser member sothat as'normally to pass through a slot 170 in as long as the said portion of the presser member is not in completely operative position the starting means cannot be operated to start the machine. In the illustrative construction this means is, therefore, so arranged that one hand of the operatoris employed in holding the movable portion of the'presser member at its extreme forward position in order to unlock the starting means and then only can the starting means be. depressed through pressure exerted by the other hand of the operator. It will be clear that the arrangement described has several advantages, one of which relates to the employment of both hands of the operator in operating the machine, so that the arrangement constitutes a safety device making it impossible for injuryto occurv to the hands of the operator. Further" more, the arrangement ensures perfect op eration of the machine in the forcing of the material through the die since the presser member which was laterally displaced to permit of accurate positioning of the work over the die must be returned to its extreme go forward or operative position before'the starting means can be actuated. As shown the movable presser member 24 carries a rod 168 extending rearwardly therefrom so the rod 150, thus locking the rod against movement downwardly to trip the clutch. Moreover, the rod 168 is of such a length that the presser member 24 must be moved to its extreme forward position before the rod is withdrawn from the slot. Preferably, the rod 168 is held yi-eldingly in itsextended position by means of a spring 172 so that upon release of the movable presser 24 by the operator and rearward movement ofthe same due to the operation of the spring 28. the rod 168 will engage yieldingly with the rod 150 should the slot 170 not be in line with rod 168 at the time the movable presser member 24 starts rearwardly. Hence the rod 168 in case it engages with the side of the rod 150 would not press so firmlythereon as to lock it against movement upwardly to its operative position to engage with the connecting link 140.

Another feature of importance disclosed in the illustrative machine relates to the operation of the magazine by which the blanks in the magazine are spaced from those in the die when the magazine has been expanded to full capacity so that the operator may readily remove the blanks, thus preparing the machine for another series of blank cutting and blankmagazining operations. As set forth in the foregoing description the magazine is expansihis, the expansibility in the illustrative construction being provided for through a movable bottom plate to which is connected va rod 92 carrying a rack 94- for co-operat-ion with the pawl 96 soithat the bottom plate is held against upward movement bythe weighted cord 80. \Vhen the magazine has been expandedto contain the desired stack of blanks, pawl m mounted 'on a lever 176 is operated to engage a notch 178 in the rod 92tomove the rod and perforce the bottoinplate78' a considerable step downwardly, where they are held through the operation of the pawl 96, whereby the blanks inthe magazine are spaced from those in the die and in the die holder, as shown in Fi ure 2 of the drawings" the front art of the ma azine is open the oerator can readily remove the blanks as will be evident train an inspection of the said Figure'QI As shown, the lever 176 is op-.

erated from the presser member 6, conne'ction being made through a link'180, as the presser member moves" up and down during pressure applying operations, all of the movements of the lever 176 being idle until thenotch 178' is finally moved downwardly far enough to'be engaged bythe pawl 174,

it being evident that when the magazine has been emptied and the bottom plate 78 is resting againstthe loweri'surface otthe bed 66 that the notch l78' will be far above the pawl 17%. lvlounted fixedly in the machineframe in a positionxto en'gage with the pawl 17% is a bar 182, shown in cross section in 2, which throws the operative end of the pawl away from the rack bar 92. As soon, 'howeven as the lever 176 moves downwardly the operative end of the pawl 17% is thrown out toward the'bar-182 by mean-s of a spring which may be of the well known leaf spring construct-ion. t

lieans is preferably provided for locking the starting means against} operation whenthe magazine hasb'een filled with the desired or predetermined number of blanks or when the magazine has been expanded as'des'cribed to permit of the removal of blanks; In the illustrative construction the said means comprises a lever 184 pivoted at 186 on the frame of the machine and connected at one end by a pin and slot connection to an upg right rod 188 guided slidably int-he machine frame and having its upper end infpos'iti'on to be contacted bythe bottom plate 78 of the magazine when the latter is moved down by the lever 176 as above described. To the other end otthe lever 184: there is connected by a pin and slot connection a secondup right rod 190 which is'locate'd'directly beneath the end ot the startinglever'1'58. The arrangement is such that when the bottom plate is moved down by the".lever 176 the:

as an unyielding stop I I. p l v p forward positiona'gainst the tension of the rod 190 is lifted to'act preventing downward movement ofthe starting lever. V YVhen removed from the blanks have been 1 the magazine and the bottom" plate 78'has been permitted tor seinto'con spring 192 which is connected tothe lever 184Lat one end and to the frame ofthe machine at its otbercnd; f

Ordinarily the Work presented to' thisma chine will consist o-fpieces otmaterial which approximate closely in" sizeto the size of the blanks: to be out theretron'rand hence the waste material which is pressed down upon the outside of the cutting edge" of thedie should be severed so t-hat it willfall readily away from the Vdieand'not; struction to cutting operations; purpose'the is preferably provided can two short wedge shapedlblades one on-each side of the die, the-one at the front-of the act as an ob- F01" this die bieing'sho'wn w ngs andindi cated by the reference character 194. The scrap severed by the blade falls from thedie on to inclined-chutes 196-wl1'ich discharge the scrap clear of the machine on each side; pref-j erably into boxesprovided for the'-.purpose of receiving the scrap. p I

In theoperation of the machine pieces of work such as that indic a-ted'at 198 :in Figs. 3' and 4 of the drawings'as having aperloration or jig hole QOOtherein at one end are presented to the gage or' jig pin 58 and threaded upon said pin and further pressed upwardly against the tripping'plunger 46 until the plunger 36 carryingthe gage or jig pin is released and projected downward ly whereby the pin is disposed with its end projecting into' the die,-the' body portion of the plunger 36" acting as a-presser foot to hold the material in the position to whicli it is adjusted by the operator. Itwillbe understood that a mere change in the-shape and size of the-die is all that is necessary toen'ablethe machine tooperate on complete or whole soles or other similar articles;

Preferably the presser member and die are" sorelated to each other when the pressei member is in" its lowermost position" that 7 there 1s a" slight space betweenthe two. In
