Be it known that I, lEnasrus E. l/ViNKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Pressing tion of the in'ventio11,fsuch as Will enablel others skilled in `the art to which it apper- The present invention relates to solve pressf 111g machines Whlch are used 1n the manufacture of boots and shoes to perform the More particularly the present yinvention extensively used to perform the sole leveling operation, Which comprises a shoe supporting jack, a cooperating sole pressing form, and means for actuating the jack and form to subject the sole of a shoe supported upon the jack to a rolling pressure.

Rolling pressure sole leveling machines are usually constructed to exert two pressures upon the sole of a shoe, one pressure being produced by the inward movement of the jack and form from a position at thenfront of the machine in Which a shoe can be readily removed from the Ijack and another shoe placed thereon, which position is termed a position of presentation, and another pressure being produced during the return movement of the jack .andform to the position ever, to subject the sole to a greater number accomplished by starting and stopping the machine several times without removing -the shoe from the jack., Machines have, :how-l ever` been devised by'Which the jackandl form are automatically* and continuously moved to produce this result, and in an lapthel machine disclosed in said application which I am familiar, the number of pressures to which the sole is subjectedy is predetermined by `the lconstruction of themachine or isdependent ufponpthe will of the operator. Thenumber of pressures necessary to' properly beat out or level a sole Specification of Letters Patent.

i ERASTUS E. WINKLEY, OF LYNN, MASSACHUSETTS, .ASSIGNOR T0 UNITED SHOE NEW JERSEY, A CORPORATION OF NEW SOLE-PRESSING 'MACHINE Patented Nov. 9, 1909. Renewed March 12, isos. seria1N0.42o,e93.

Varies with the thickness of the sole, and an object of my invention is to provide a sole pressing machine by Which soles of different thicknesses will be subjected to the required number of pressures. With this object -in View, my invention broadly considered contemplates providing a sole pressing machine comprising a jack and ajfo'rm and means for relatively actuating the jack and form to press the sole of a shoe supported upon the jack with means controlled by the thickness ofthe sole of a shoe for determining the number of pressing operations to Which the sole is subjecte I believe that I am the first in the art to provide a'sol'epressing machine of any description in Which the number of pressures exerted upon the sole of a shoe 1s determined by the thickness of the sole, and I therefore consider this feature of my invent-ion as broad and generic in character and as capable of embodiment in otherxforms ofsole pressing machines as well as in that form in which the sole is subjected to a rolling pressure. VVhilethis feature of my invention broadly considered may be embodied in any sole pressing machine `comprising a shoe supportingjack and' a cooperating sole pressing form, it is preferably embodied in 'a machine in which the jack and form are actuated to subject the sole of a shoe to a rolling pressure as it is of specialimportance lin this class of machines to subject the sole to .a number of pressures to beat out` or level the sole.

In the machine disclosed in my application above referred to and in all other rolling pressure sole leveling machines With Which I am familiar in which mechanism'is provided which operates to move the jack vand form'to'subject the sole of a shoe supported upon the jack to a plurality '0f rolling pressures and in which the jack is stopped automatically in a position of pres-l entation, no means forming -a permanent part of the machine are provided for varying the'number of'pressing operations to properly7 which the sole` is subjected, the same number ofv pressures being exerted upon a thin -sole'as upon a thick sole.' I believe that I am the first to providel suclra machine with meansl permanently embodied therein for varying th-e number of pressing operations Qto which the sole is subjected Whether such n ieans-are controlled by the thicklfcss of the `forming a ypermanent sole of a shoe or are controlled by any other means or by the operator, and I accordingly consider a feature of my invention to consist in providing a sole pressing machine.

comprising mechanism acting to move a jack 'and form to subject the sole of a shoe to a plurality of rolling'pressures, and meansl acting Aautomatically to stop the jack in a position .of presentation, with any means part of the machine for varying the number of pressing operations to which the sole is subjected.

The machine which I have disclosed herein as embodying my invention in its pre.'-

-ferred form in addition to the broad features of invention above referred` to embodies other features of invention hereinafter dej scribed and claimed, the advantages of which 'will be obvious to those skilled in the art. As to these features of invention it is tobe understood that except as specifically dened inthe claims they are not limited to any particular construction or arrangement of parts but may be embodied in constructions other thanthose illustrated and hereinafter described without departing from the spirit thereof.

Referring vto the drawings, Figure 1 is a view in side elevation of the upper portion ,of a roller pressure sole leveling machine embodying a-preferred` form of my invention; Fig. 2 is a view inside elevation of the lower portion of the machine, this ,figure in connection with Fig. l forming a view in side elevation of the complete machine; Fig. 3 is Aa. view in front elevation of the upper portion of the machine with the two arms by which the sole pressing forms are supported swung rearwardly into a vertical position; Fig. l is a sectional plan view and 6 are detail views of the mechanism for reversing and stopping the driving shaft of the machine;

taken on the Vline 7-.-7 of Fig. 4 illustrating a portion of the mechanism by which the number of pressing operations to which the sole of a shoe is subjected is controlled; Fig.

The machine illustrated in the drawings is a duplex rolling pressure sole leveling machine ofthe same general type as the sole leveling machine disclosed in United States patent toTripp No. 296,486, dated April 8,

Fig. 7 is a detail sectional viewl 1884. The machine comprises two pivotally mounted arms upon which the sole pressing forms are supported and two pivotally mounted arms upon which the shoe supporting jacks are supported, the arrangement of the arms beingl such that when two of the arms supporting .a jaclg and a cooperating form respectively are oscillated the sole of the shoe supported upon the jack is subjected to a rolling pressure. The two sets of arms are oscillated by means of a common actuating mechanism which comprises a driving shaft, through connections between the driving shaft and the arms. The driving shaft is rotated alternately in opposite directions, means the reversals in the direction of rotation are produced automatically, and the connections between the driving shaft and the pivotally mounted arms are such that the direction of the oscillation of the arms is changed with each reversal in the direction of rotation of the driving shaft.` When the machine is at rest the pivoted arms are at the extreme limit of their forward movement, the jacks and forms being separated to allow shoes to4 ,be removed from or placed upon the jacks.

During the operation of the machine one pair of arms upon which a jack and its cooperating form are supported are moved from the position at the front of the machine, which position is termed a position of presentation, toward the rear of the machine to subject the sole of the shoe supported upon the jack to a rolling pressure and are then either returned to the position of presentation at the front of the machine thereby subjecting the sole of kthe shoe to another rolling pressure, or are moved forward and baclrone or more times through a lesser varc to subject the sole of the shoe to a number of rolling pressures and then finally returned to the position of presentation at the front ofthe machine.l During the movement of one jack and its cooperating form to level being provided by which th'e sole of a shoe the arms supporting the other jack and form are disconnected from the actuating mechanism, means being provided for connecting and disconnecting each set of arms and the actuating mechanism so that one jack and form can remain 1n a position of presentation while the other jack and form are being actuated to level the sole of a shoe and return the jack and form to a position .of presentation. When the jack andform are returned to a position of presentation the arms upon which they are supported' are automatically disconnected from the the driving shaft is automatically stopped. ln order to vary the number of pressing operations to which the sole of the shoe is subjected the machine is provided with means controlled by the thickness of the sole of the shoe upon the jack for determini ing the number of oscillations imparted to the arms upon which the jack and form are supported before the jack and form are returned to the 4position of presentation'.-

' returned to the position of presentation.

lIn the drawings 1 indicates'arms, two in nu1nber,`pivotally,mountedat 3 in the upper front portionof the machine frame 4.`

5- indicates two armspivotally mountedl i in the machineV frame at 6 belowthe arms 1.

The sole pressing formsyare supported upon the arms 1 and the jacks are supported upon the arms 5, the arrangement of the arms 1 and 5 being such that the forms upon the arms '1 coperate with the `jacksupon the arms 5 to subject the soles of shoes supported upon the jacks to a rolling pressure when the arms are oscillated.l The jacks, which are not illustrated, may be of'any suitable construction adapted to supportashoe and may be secured to the arms 5 in any customary or desired manner. The forms are also not shown on the drawings and may be of any usual or desired construction.

These fomnsare secured, as is common in this-class of machines,.`to form-carrierseach of which consists of `a plate 7 provided with,

a stem 8 mounted-to slide in one of the arms 1. `Each form carrier is pressed down` wardly by al series of springs 9 supportedy upon a vrod '10 and interposed between acol-l lar on therod and anl upwardly projecting portion of the "plate 7 the u per'end of the rod l() having a screw-threa ed4 engagei'nefut` with a *lug projecting from the arm lland having a sliding engagement "with thet up'- wardly'extendin portion of the plate The form carrier 1s also pressed .downwardly by means of a seriesof s'prings'll surrounding-a-rod 12 having a screwlthreaded ,en-` gagen'ient at its upper end' with the larm l and having a'sliding engagement at its lower end with the stem 8, the springs being interposed betweenja collaron the rod and the upper end of the Istem-8. `The form carrier is thus yieldingly forced toward the jack and is allowed to rise as the jack and form are swung' from the front toward the rear of the machine to bring the form into conf tactwith the sole of the shoe and tov subject the sole to a rolling pressure. i 4It willbe `evident that the ldistance' to which the form carrier is raised will vary 'with the thickness of the sole of the shoe being operated upon and this varying movement of the form carpressing `operations to which the sole is subjected as will be hereinafterv described.

' Each ofthe arms 1 and 5 is provided with a toothed segment 13 which meshes with one of four worms 14 upon-two vertical shafts 15. Each shaft 15 is provided with a gear 16 which meshes with a gear 17 upon the upper end of a' short vertical shaft 18. vThe shaft 18 is provided at its lower end witha bevel gear 19 which meshes with a bevel gear"20 upon the main driving shaft 21. The above-described construction is such that both shafts 15 are rotated in the same direction, the direction of rotation of the shafts 1'5 depending on the vdirection of rotation of'the shaft 21.

In order to oscillate either jack and its cooperating form backward and forward from -a position at.the front of the machine'to levelthe sole of ar shoe-sup orted upon the jack the main driving shaft 21 is rotated alternately in opposite directions. Tol this end driving pulleys 22 and 23 are mounted to rotate loosely upon opposite ends of the driving. shaft 21 and to bey capable of moving longitudinally thereon. These pulleys are continuously driven in opposite directions from any suitable source of power.

-Rigidly secured to the opposite ends of the main driving shaft are frictional

clutch members

24 and 25 with which coperating clutch members upon the pulleys 22 and 23 are arranged to be brought into engzugement,v in order to clutch either pulley to the drivshaft. The pulleys 22 and 23 are pro- 1n vided with grooved collars which are engaged respectively by arms'26l and 27 secured to a shipperrod 28.

The arrangement of the' shipper rod 28 andthe

arms

26 and 27 is suclrthat'when the shipper rod is in its 4-medial vposition both pulleys are disconnectf ed from the

clutch members

24 and 25 and vrotate loosely upon the driving shaft. Then y i the shipper rod is moved in one direction the pulley 23 is moved into enga ement with the clutch member 25 andthe rivingshaft is rotated in onedirection and when :the ship. 'per rod is moved in the 'opposite direction -the pulley 22 is moved into-engagement with vthe clutch member 24 andthe direction of rotation of the driving shaft is reversed.

In the machine shown in the drawilpigs, means are provided for automatically actu'- ating the shipper rod 28 to reverse the direcjack andare finally returned to the position Vof presentation at the front of the machine. The means for actuating the shipper rod 28 y ,to reverse the direction of rotation of the rier is utilized to determine the number of driving shaft will be clearly understood ilo from an inspection ofFigs. and 6. 4Referring to "these figures 29 indicates a Worm upon the main driving'shaft which is engagedA by a traveling nut30. This nut has l atpm and slot connection with the upper end a lever 31 pivoted at 32 to the frame of the machine. The lever` 31 is connected byl `means of a link 33 to an arm 34 projecting from the hub of a bell crank lever 35 `pivoted' at 36 to the frame'of the machine. The

' two arms of the b'ell crank lever 35 are connected by means of links 37 to the distance arm's 38 pivotally mounted upon a shaft 39 wheel and the shaft 39 to whichit is secured are intermittently rotated as the nut travels by leaf springs 42.

upon opposite sides of a ratchet wheel 40 1.5

back and forth on the worm 29, one pawl 41 being in engagement with a Atoothwof the ratchet wheel. when the nut is traveling in one direction and the other pawl being in l engagement with the. teeth of the ratchet wheel when the nut is traveling in the opposite direction. Also secured to the shaft 39 is aI disk 43 provided on one face with a cam groove 44 and on the opposite face with a series of cam projections 45. The cam groove 44 is engaged by a roll or stud upon the lower end of a lever 46 pivoted at 47 to the frame of themachine and having a in andislot engagement at itsupper end with a collar 48 mounted to slide upon the shipper rod 28. Two

collars

49 and 50 are secured to the' shipper rod upon opposite sides ofthe collar 48 and coiledsprings 51 and 52 surround the shipper rod and are interposed between the

collars

49 and 50 and the loose collar 48. The c'ollar 50 ha'sra pin and slot 45A lever 53 pivoted at\54 to the frame ofthe machine and. provided at its lower end with connection with the upper end of a locking a lroll or stud which is arranged to b e engaged by the cam projections'45 on lthe disk 43. The arrangement of the -

levers

46 and 1 53,t he cam groove 44 and the. cam projections 45 is such that as the shaft 39 and the cam disk 43 secured thereto are rotated the shipper rod 28 is held from movement by' the engagement of the stud onthe lower endof thelockin lever 53 with either the outer or inner sur ace of one of the cam projections 45 until the collar 48 has been moved by means of the lever 46 and cam groove 44 to compress one of the springs 51,01-l 52. After the spring has been compressed the continued movement of the cam disk 43 'Y movesthe cam projection 45 out of engagelment with-thc stud on locking leverv 53, thereby releasing the leverand allowing the spring which has been compressed to move. t e shipper rod 28 to reverse the direction of rotation of the driving shaft. The stud on the lower end of the locking lever 53 1s alternately engaged by the outer and inner surfaces of the cam projections 45 so that the shipper rod is held alternately in its extreme positions to the right and to the left with one of the driving pulleys clutched to lthe driving shaft.

The machine illustrated in the drawings is designed to impart to the jack and form connected to vthe driving shaft a relatively long movement from a position of presentation at the front of the machine to a position of pressure and thereafter either to return the'jack and form at once to the position of presentation at the front of the machine or to impart a number of shorter intermediate movements to the jack and form and then return them to the position of presentation. The ratchet Wheel 40 illus-v turned to the position of presentation at the front of the machine,rmeans are provided for adjusting the connections between the traveling nut 30 and the ratchet Wheel 40 to allow the nut to travel varying distances before moving the shaft 39 through an eighth of a revolution. To this end tne link 33 is connected to the lever 31 by means of a pin passing through the slot 55 in the lever 31.. When the link 33 is raised with the pin in the upper portion of the slot it will be evident that a shorter travel of the nut 30 is required to move the shaft 39 through an eighth of a revolution than when the link 33 is in its lowered position with lthe pin in the lower portion of the slot 55. The link 33 is automatically raised and lowered during the operation of the machine as will be' hereinafter described.v When the machine isat rest with the forms and jacks started'into operation the link 33 is raised during the inward movement of the jack and form and; is-held raised until the jack and form enter upon their nal outward 'movement Durmg the final outward movement the link 33 is lowered and the nut 30 is allowed to travel back to its original eX- end the nut is,

at the completion of the 4leveling operation.

, The final Imovement 'of' the nut 30' t its eXtreme position at the leftas viewed in Fig. 5 is utilized to disconnect both driving `pulleys from the main driving shaft. To this 56', see Fig. 4) which is varranged to engage a movable stop 57 pivotally mounted upon a' block `58 lwhich is pivoted so as to be cap p'able of'swingmg vertically upon 'the frame ofthe machine. When the nut reaches itsy extreme -position at the left the projection 56 contacts with the stop 57 and moves `into the the shipper rod is actuated 'so that when the it into thepath of a stop collar 59 4secured to the shipper rod.

Splined upon each rod 70 is an arm`71 which has Ja pin and slot connection witha link 72"'connecting the arm 71 to an `arm f3-projecting .upwardly from the rock shaft 62. The above* described connections between 'the' treadles 64 and the rock .shaft 62'are such that when provided with afprojection' y shafts 15 and with y'thestopv collar 59,.'tliis.

In the machine illustratedlin the drawings, bothl jacks and their coperating forms are disconnected from the driving shaftv when the jacks and forms are in the p osition .0f presentation at'the frontof the machine. Either yjack and its cotiperating form can be connectedto the driving shaft so as to be actuatedto level the sole of a shoe and to return to a position of presentation, the

other jack 'and form remaining in the posi-v tion of presentation disconnected from the drivingshaft. In order to allow the jacks and forms to be connected to and disconnected from thewdriving shaft the gears 16 -are mounted to` rotate loosely upon the are provided with clutch members which are., arranged to be engaged by clutch members 74 splined upon the shafts and mounted to move longitudinally thereon. Each clutch member 74 1s acted upon by a spring 75 coiled around a shaftl 15 and interposed between a fixed collar 76 and a clutch member 74, g the tendency of the springs being to force the clutch members 74 into `engagement with the clutch members 4on the gears 16. Each clutch member 74 is engaged by an army 77 secured to the upper end ofa rod 70. A spring 78 surroundin 70 and interposed between the bearing for the upper end of the rody and the arm 77-`tends to lf orce the rod downwardly; A projection 79 on a plate secured to each of the arms 5 is arranged to engage a block 80 secured to the rod 7 O when the arm -5 is swungto return the jack to its position `of. presentatiom the engagement of the projection 79 with the block 80 lifting theirod 70 to automatically disconnect the clutch member 74 from lthe clutch member the clutch members jack remains in the position of presentation. When the machine is thrown into operation either treadle 64. the oscillation of the corresponding rod 70 moves the block 80 out of engagement with'the projection'79 and allows the clutch member 74 to move into engagement' with -the clutch member of the lgear 16.

In order to insure that each jack and its coperating form shall be disconnected from itsactuating mechanism when returned 'to a position of presentation, the projections 79 are so arranged as to bebrou ht into engagement with the blocks 80 be ore the rotation of the main driving shaft is stopped; and inv order to in'sure that each jack and form shall be connected to its actuating 'mechanism at the same point in the travel by the depression of y j ation of the rod. 70 to move the blocks 80 out the driving 'shaft has been thrown into operation and the nut 30 has traveled a certain distance on the worm 29. The means for preventing the actuation of therods 70 to remove the blocks 80 from engagement with the projection 79 until thenut 30 has trav- `eled a certain distance on'fthe 'worm 29 consists of a stop plate 60a adjustably secured to4 the bent lever 60.' VWhen the; machine is started into operation bythe depression of a treadle 64 the'plate 601- contacts with th`e nut 30 or its projection 56 'and prevents the treadle 4being depressed a suiiicient dstance to actuate a rod 'so as :to remove a block from engagement witha projection 79,. The treadle v64 is, however, depressed a suiicient distance to move the stop- 57. out

of engagement with the stop collarl59 on the; shipper rod'. After the driving-shaft 21 is thrown into operation the nut 30 is moved from beneath'the plate 60a^`and the treadle is allowed to complete its movement so as to lactuate the rod 70 to remove the block 80 Afrom engagement with the projection 79.

It will be evident that the number of pressing operations -to which the sole of a shoe is subjected will depend u pon the timfe during vthe operation lof the machine at which the link 33 is moved into its lowest position. ln the machine illustrated in the -drawings the link 33'is movedfbymechanism which is thrown into operation at Aa time during the operation of the machine determined by the thickness of the sole of the shoe being operated upon. The link 33 is connected by means of a link 81 to one arm of a lever v82 pivotally mounted upon a rod 83 so as to be capable-otmoving longitudinally thereon'. The other arm of the le- !ver 82 is provided with a roll or stud 84 which is arranged to be engaged by a cam 85 secured to the shaft 39. Vhen the stud 84 is upon a raised portion of the cam 85 the link 33 is held in its lowered position, but when the stud is out of engagement with the cam or in contact with a low part of the cam, the link 33 is held in its raised position. During the greater portion 'of theoperation of the machine the stud 84 is -held out ofthe path 'of movement of the cam 85v by means of a spring 86 surrounding the rod 83 and tending to force the .lever 82 to the left as viewed in Fig. 4. The lever 82 is moved fto bring the stud 84 into the path of movement of the cam 85 by means of a timing cam 87 i secured to the shaft 39. This timing cam is provided with a 'series of cam grooves as is clearly illustrated in Figs. 8 and 9, one of which, while the machine is in operation, is in engagement with a finger projecting from an arm 88 pivotally mounted upon a sleeve 89 mounted upon the rod 83l `so as to move longitudinally thereon. The arm 88 is pressed toward the cam 87 by means of a spring 90. When the machine is at rest, thearm 88 is in its entreme position at the right as `.viewed in Fig, 4, the ingenof the arm being at the end Otone of the cam grooves.

eling'a shoe, the arm 88 is raised by means engages the end of the arm and the arm is 'moved to the left and its linger brought into engagement with vone of the grooves of the timinggcam 87. The point on the timing cam which is engaged by the finger of the arm 88 is determined by astop cam 92 which is mounted to rotate loosely upon the shaft 39 and which covers up a portion of the timing cam. A bevel gear 93 is secured l-tothe stop cam 92 and meshes with a bevel gear 94 upon the lower` end of a vertical A.shaft '95. To the upperend of the shaft 95 is secured a gear 96 with whichmeshes a rackf97 carried by an arm 98 secured to a rod 99 mounted to slide 1n bearings 1n the .upper front portion of the machine frame.

To the rod 99 are secured two segmental -connections between the form carriers and the stop cam 92 are such that the upward movement of either form carrier causes a rotation of the stop cam, the amount of rotation depending uponA the extent of the "upward .'movement of the form carrier vwhich in turn depends upon the thickness During the lirst inward movement of the jack and form 1n levshaped plates 100 againstthe sides ot' which the' upper ends of arms 101 bear. The arms of the sole of the shoe being operated upon.

Acoiled spring 104 surrounding one end of the rod 99 and interposed between a collar on the end of the. rod and one of the bearings for the rod tends to hold the rod in its extreme position toward the left as view in Fig. 3. The stop cam 92 illustrated in the drawings (see more particularly Figs. 10 and 11) is provided with three portions marked respectively a, Z) and c, which are designed to 4be engaged by the linger of the arm 88 and determine the point on the timing cam which is to be engaged by the arm. In the machine shown in the drawings, ,if the shoe being operated upon has a thin sole, the stop cam 92 will be rotated so as to bring the' portion a of the cam into the path of movement of the finger on the arm 88 and the arm will be engaged by the timing cam so as to be moved a sutlicient distance lo bring the stud 84 oli the lever 82 into the path of movement of the cam 85 during the Erst outward movement t the porton of the in its medial position by 88 and the lever cam 91 and the stu esame of the jack and form. When, therefore, the stopcam 92 is set to cause its portion a to engage the finger of the arm 88 the jack and form will be moved from a positionof presentation toia positiontjof pressure and immediately returned to a position of presentation.v When thicker soles are o erated upon the cam 92 ciently to bring either into the path of movethe' portion b or c on the arm 188 and the ment of the finger ,arm will not be moved by the timing cani to of the lever 82 into the f brlng the stud 84 path of movement of the cam 85' until a number of shorter intermediate movements are imparted to the jack and form before position of presentabelng returned to the tion. In' the machine shown in the drawings one shorter movement in each dlrection will be imparted to theiackvv and form when a the portion. b of the stop cam 92 limitslthe movementy of the farm? 88 and two interl'ne' diate shorter movements in each directionA will be imparted to the jack and form when stop cam limits the movement ofthe' arm 88. is .raised and* moved backward to lbring the finger thereon into engagement" withV a-I groove of the timing cam, the finger ispre-l vented from drepplng into a groove until it strikes the st p. cam by means of a spring pressed fingerlO (see more particularly Ilig..12).

The operation ofthe machine above described is -as'ollows :f-When the machine is 'at rest bothl the jacks and their coperating" forms are in the position of presentation at the front ofthe" machine, both .rods are".

held raisedby the enga ement of projections 7 9 with blocks 80, the s ipper rod 28 is held the engagement ,of the stop collar 59 with the stop 57 andboth the vdriving pulleys are .disconnected from the driving shafts. The spring 51 surrounding the shipper rodis compressedtending to as viewed force the shnpper rod tio-the left in Fig. 6 an the stud on the lower end of ythe lockinglever 53 'is opposite a space be-I tween two of' thefprojections 45. The arm 82 are in their eXtreme-position at the right 'as viewed in Fig. 4, the end of the arm 88 bein in engagement with the d 84 of the-lever 82 being upon a raised portion of the cam 85. A shoe "having been placed upon one of the jacks, the 'treadle on thatside of the machine is depressed. The depression of the treadle -first releases the shipper rod as has been described and then. releases the rod 70 connected with the jack which is to be thrown into operation. The driving shaft is thus connected to one of the driving the jack upon which the shoe has been placed and its coperatiug form are connected to the driving shaft.

a described. During When the arm-88 i time acting to path combination,

pulleys andl During the first inward y movement of the carrler 1s raised described. During the inward movement of the jack and form and after'the stop cam 92 has been operated, the cam-,91 raises the arm 88 and allows the spring ,86- to force the lever 82 and the arm 88 to the 'left asviewed in Fig. 4. The move ent of the arm 88 and of the lever82 tothe left is limitedl by the contact ofthe linger of thev arm 88 with the stop cam 92, the linger dropping into one of they grooves of the timing cam 387. The finger engages one of thestraight portions ofthe groove andis moved bythe inclined 'portion of the v groove during the outward movement ofthejack and'form. :The driv'- ing shaft iis rotated alternately in lopposite directions and the'shaft 39 is rotated step by step throughl the; connections hereinbefore the rotation of the shaft-.

39 they arm -88 is moved toward the right as lviewed in Fig`.f4 by .the engagement of the 'timing cam with the finger of thearm 88 and during one ofthe outward movements of the jack andfform the cam 82 into the the cam 85, which acts to depress the link and thereby 4delays the action of the reversing mechanism until the jack and form are returned to t-he movement ofthe nut 30 to its .extreme positi'on at ftheleft (as viewed in Fig. 5) at this` a throw the stop 57 into the of movementof the stop collar 59 so as to arrest the shipper rod 28 in its medi-al position when the reversing mechanismy operates.
