This invention relates to edge setting machines, and especially, although not exclusively, .to'machines for4 setting the edges of toplifts attached to the heels of boots and shoes.

-The invention has for its general object to provide an automatic machine for rapidly and accurately performing all of the required operations upon the edge of auf-attached toplift or the like, said machine being capable of rapid operation and of a relatively large output of high-grade work of even quality lwith a "minimum of skilled attendance, and being adjustable to adapt the same to work of a wide variety of shapes and sizes.

The operation of settin the edge of an attached toplift has for its o jectsto finish and polish the raw edge of a toplift which has been previously inked and waxed, to roll in the joint between the toplift and the heel so as to close said joint and make the surfaces of the heel and .toplift smooth and continuous, and to mold the edge of the toplift so as to form thereon-a lprojectin circumferential d, or surface be 4 tween' the bead and the heel proper, and a portion known as the pane at the outer side of the bead, which last-named portion is subsequently buiedy oi in the final finishing of j 3o the toplift to bring the bead flush with the outer surface. These operations. are usually vperformedby1 ya heated iron having a conliguration substantially complementary' to the desired configuration of the bed, bead and panel, and which is'so manipulated with referenceto the edge in question as to produce the several results above referred to. 'The lff tends to unset the'material of thelatter,

which results-in what is known as pouting v or cupping of the toplift',v that is to say, a'

spreading of the material at the panel portion of the edge which causes the free'outer face ofthe toplift to assume a more or less concave form. Since the purpose of forming the panel is to leave room for subsequent buiing of the outer face without'cutting into the bead if said outer face has assumed a concave form, the builing necessary to restore it to its stroy the ead notwithstanding the provision of the panel. In order to avoid pouting or cupping it is necessary to shape and manipulatethe iron in such a manner as to exert a pressure heightwise of the heel against the outer face of the toplift sufficient to oifset this tendency. In addltion to the manipulation of the iron. necessary'to prevent pouting and .its relative movement circumferentially of the toplift edge, said iron must also be rocked toward the heel to roll in the joint between the latter and the to lift. Furthermore, the relative movement og the iron and toplift in order to cause the former to travel circumferentially of the latter must be about an axis which is accurately erpendicular to the plane of the 'bottom face ofthe toplift in order that the resulting bead maybe accurately arallel to said bottom face. v

In e setting machines as heretofore constructe the foregoing operations have all depended to a large extent upon the skill of the operator and have been slowv and laborious. Moreover, they have usually been aecomplished by short, repeated, local strokes of the iron, whereas for the best results and to prevent uneven heating, long, even strokes extended about the entire circumferential prtion of the edgel to be finished are desira e.

The present invention has for an object toprovide a machine in which the several factors above referred to are deinitely predetermined, by suitable adjustments in accordance with the particular work being operated u on, without further attention on the part o 4the operator, whose sole duty-thereafter consists in insertin and removin the work, the operation o the machine with a given set-up being otherwise wholly automatic. .Another object of the invention is the'provision of a machine of this character in which the' edge setting-strokes are long and continuous from en'd to end of the surface to be finished, and whose of operation, and consequent output, 1s greatl increased over machines of -like purpose as eretofore used.

plane form may be suiicient to vde by suitable adjustment, as to cause the full` length of the edge surface to be finished to be traversed by the iron at each oscillation; automatic means for operating the iron during the oscillation of the jack to cause the same toroll in the joint between the toplift and the heel, said means being adjustable to vary the movement of the iron 'in accordancewith requirements; means for interrupting the oscillation of the jack after a predetermined number of strokes, for operating said jack to release the work, and for withdrawing the iron therefrom in order to permit the finished work to be removed and new work to beinserted, and for thereafter causing the jack to clamp the work, the iron to be applied thereto, and the oscillation of the jack 4to be resumed; means for automatically controlling the pressure applied by the iron to the work; and means for so Vsupporting the iron that a portion of its pressure against the edge of the toplift is converted into a pressure heightwise of theheel to prevent -pouting Theforegoing and other objects and features of the invention, together with means whereby the latter may b e carried into effect, will best be understood from the following description of a preferred embodiment thereof illustrated in the accompanying drawings. It will be recognized, however, that the particular construction described and shown has been chosen for purposes of exemplication merely, and that said invention, as defined by the claims hereto appended, may be otherwisev embodied without departure from the spirit and scope thereof.

Referring to Figs. 11 to 13, A denotes a portion of a Louis heel and B a toplift secured thereto. Fig. 11 shows the topl1ft B in the condition in which it is applied to the heel, and Fig. 12 said toplift after the operation of the machine thereon, the-effect of said operation being to finish the'rough edge ofsaid toplift, to roll in the joint a between the heel and toplift, and to form on the latter the bed b, bead c and panell d. In the operation of subsequently finishing the outer or exposed faceof the toplift B, the panel portion al is buifed oil", leaving the bead c substantially flush with said outer face, as shown in Fig. 13.

Referring to Figs. 1 to 4, 20 denotes the frame of the machine which is suitably designed to provide the necessary bearings, supports and guides for the various parts hereinafter described.

Journalled in the frame 20 is a power shaft r 21 having thereon a pulley 22 adapted to receive a belt (not shown) through which power may be applied thereto from any suitable source. Fast-on the shaft 21 is a pinion 23 which meshes with a gear 24 rotatably mounted on a stud 2 5 projecting from the frame 20.. The gear 24 meshes with a gear 26 loosely mounted on the mainldriving shaft 27 journalled in suitable bearings in the frame 20, said Agear being attachable to and detachable from said shaft lby means of a suitable clutch 28 under the control of a manually operated lever or handle 29. Fast y on the shaft 27 is a pinion 30 which meshes with a gear 31 on a cam shaft 32 journalled in suitable bearings in the frame 20.

Journalled respectively in bearings 33 and 34 in the frame 20 are the alinedsections 35 and 36 (see particularly Fig. 14). of a twopart ack shaft, the ends of sai d sections being spaced from one another and being connected with a split hub 39 abutting the bearing 34 and secured to the-end of the shaft section 36 by aclamping bolt 40 and spline 41, thereby permit-ting longitudinal' adjustment of. the shaft section 36 in the'hub 39.

Secured to one end of the main driving shaft 27 is a crank arm 42 (Figs. 1 and 3) having ways to receive a slide 43 .adjustable therein by means of an adjusting screw 44. Pivoted to the slide 43 is one end ofa pitman 45 the lopposite end of which lis pivoted to a block 46 slidable, ina slot 47 in a gear segment 48 pivoted at 49 to the frame 20 and meshing with a. pinion 50 secured to the outer end of the section 35 of the jack shaft. The block 46 is normally held in theupper end ofthe slot 47, toaiord a driving connection between the pitman 45 and segment 48, by means of a dog 51 pivoted at 52 to said segment and normally held in operative position by a spring 53 (Figs. 1 and 2). The dog 51 is formed with a foot 4 which depends into the path of movement of a pin 55 projecting from the face of the gear 31 which vthereby constitutes a controller for said dog.

It will be seen that with the block 46 locked in its operative position .in the slot 47, the jack shaft and work holder will be oscillated from themain driving shaft 27 through the crank 42, pitman 45, segment 48, and pinion 50, the amplitude of oscillation being determined, in accordance with the arcuate'or circumferential length of the edgeof the particular style of toplifts to be operated upon, by adjustment of the slide 43. After one revolution ofthe gear 31, which may be designed to correspond to any desired number of oscillations of the jack, the foot 4 is engaged by the pin 55, causing the dog 51 to be disengaged from the block 46 leaving the `latter free to reciprocate in the slot 47. 'The ack therefore will'remain idle during one complete rotation of the shaft .27, this being the unloading and loading period in the cycle of operations of the machine during which period onev completed piece of work is removed from the machine and a newl piece inserted. Upon the completion of one rotation of the shaft 27, the

' pin 55 moves out of engagement with the foot *4, permitting the spring 53 to restore the dog '51 to its normal position, thereby again locking the slide 46 to the segment 48, and the oscillation of the jack is resumed or continued. x

The means for positioning and clamping the work in the jack comprises a toplift restor plate 56 for engaging the outer face of the toplift B, a breast gauge 7 for engaging the breast of the heel A, a heel seat support 58 carrying/a detachable positioning plate- 59 for engaging the heel seat portion of the heel A, and one or more (preferably two) spurs 6 adapted to be projected into the ma, terial of the heel at the heel seat end to sc -4 cure the same ih position.

vbeing chosen which is of substantially The toplift plate or rest 56 is carried by the jack shaft section 35 which is formed with an axial bore to receive an attaching stem 61 formed on said plate or rest and engaged at its end by an adjustable abutment screw 62 in threaded engagement with the outer end ofthe bore in the shaft 35 and having a knurled head 64 by which said screw, and consequently the position of the toplift plate heightwise of the heel, may be adjusted longitudinally of the shaftgthe adjustment being fixed by a lock nut 65. Adjustment of the toplift plate or rest 56 positions the topliit heightwise of the heel with reference to the particular iron employed. The breast gauge 7 (Fig. 2) has a shank portion slidably received in the yoke 37 and secured therein in adjusted position by aO clamp screw 66. The breast gauge 7 positions the Iheel horizontally and its adjustment adapts the machine to heels of varying shapes in order that the axis of'curvature of the toplift edge may substantially coincide, in the horizontal plane, with the axis of oscillation of the jack, that/is to say, the common axis of the shaft sections 35 and 36.

The vertical positioning of the heel, in order to, bring said axes substantially into coincidence'in the vertical plane, is effected by the sense of touch of the operator with the assistance of the heel seat centering plate 59y gage notches in studs 68 formed on the plate.

Interchangeable plates 59 corresponding to different widths of heels are provided, a plate the same or only slightly greater width than the particular heels to be operated upon (see Fig. 14). In inserting a heel, when the opposed clamping devices are drawn apart, as hereinafter explained and as indicated in Fig.' 5, the operator grasps said hel adjacent the heel seat portion thereof between hisvh thumb and forefinger, places said heel seat portion against the plate 59 with its peripheral edge irmly in engagement therewith, at the same time, by the sense of touch, centering or positioning said heel seat portion inpsymmetrical relation to the edges of said plate 59, and slides the heel into place bn said plate until the breast of the heel engages the stop or gauge 7. It is found in practice that the heel can be very quickly and accurately centered on the plate 59 by the sense of touch, as above described, since said lheel and plate are so nearly of equal width.

The heel seat support 58 (Figs. 1, 2, 14 and 16) is pivoted for angular adjustment about an axis transverse to the heel. upon alined\ lprovided with-,a projecting arm 71 movable over a scale 72 (Fig. 2) on a segment 73 carried by the sleeve 70, said arm 71 carrying a clamp screw 74 which cooperates with a. slot 75 in said segment,'whereby the heel seat support may be secured in any position of angular adjustment. This angular adjustment of the heel seat support 58 adapts the machine to heels having heelseat portions of different inclinations.

It will be observed that the positioning of the heel with the plane of the face of the toplift accurately perpendicular to the .axis of relative oscillation of the work and iron, or, in other words, with theaxis of curvature of the toplift edge accurately parallel to said axis of oscillation, is effected-solely by the engagement of the peripheral edge of the lheel seat portion of the' heel with the plate 59. The

toplift rest or plate 56 plays no essential part in performing this function and may, if desired, be provided with` a cushioned or roughened surface to. assist in securely clamping the work. By reason of the fact that the heel seat portion of the heel, notwithstanding its usual concavity, has its peripheral edge lying in a plane, this plane can'be utilized for the purpose in question to effect a more accurate positioning than is possible by any means cooperating with the toplift, since the latter is of relatively small area in proportion to that circumscribed by the edge of the heel seat, and is relatively more yielding and irregular. It will ber understood that the parallelism of the axes of curvature and os-l cillation is thus obtained by the flatwise engagement of the heel seat edge with the plate 59 irrespective of its position thereon, while the substantial coincidence of said axes isobtained by centering said heel seat on said plate and engaging the heel breast with the gauge 7, as above explained.

The sleeve 70 is held against turning on the plunger 76, and its longitudinal sliding movement thereon limited to provide a limitedv lost-motion connection between said parts, by means of la stud 78 (Figs. 2, 5 and 16) carried by said sleeve and engaging a short groove 79 in said plunger. The sleeve 701 is normally projected toward the toplift rest or 'platea' 56, to the extent permitted by the interposed work and by the engagement of the stud 78 in groove 79, by means of a spring 8() interposed between a shoulder 81 on said sleeve and the adjacent end of the jack shaftV section 36. j

The spurs 6 are carried by the end of the I plunger 76 and project through an opening 82 in the plate 59. The plunger 76 is secured by a pin 83.to the end ot'A a rod 84 longitudi nally movable in the bore 77 'said plunger 5 being normally projected toward the topllift l plate or rest 56 by a spring 85 surrounding the rod 84 and interposed between the plunger 76 .and a shoulder 86 formed in the bore 77. The 'rod 84 is extended4 to the outer end of the j ack the bell crank shaft section 36 and is provided with a head l 87 having a transverseopening or socket 88 to receive the rounded end of one arm of a bell crank 89 (Figs. 1, 2, 4, and 14) pivoted at 90 between ears 91 on the outer end of the jack shaft section 36. The other arm of the bell crank 89-is periodically engaged by an elongated head 92 on a lever 93 pivoted at 94 to the frame 20 and carrying a roller 95 which cooperates with the edge of a cam 96 on the cam shaft 32, said roller being held in engagement with said cam by a spring 97.

vWith the parts in the positions` shown in Figs. l, 2, 4, 14 and 16, the roller 95 is on the low part of cam 96, the head 93 is disengaged from the bell. crank 89, and the springs 85 and 8() operate to project the spurs 6 into the heel and force the sleeve with its attached heel seat support 58 toward the toplift rest 56, thereby clamping the heel in position in the jack.4 When the roller 95 is engaged by the high portion of the cam 96, the lever 93 is oscillated to cause the head 92 to engage and operate the bell crank 89, thereby drawing the rod 84 outwardly. The first eifect of this movement is to withdraw the spurs 6 from the heel,after which the stud 78 is engaged by the end of the groove 79, thereby picking up the sleeve 70 withits'attached heel seat support 58 and withdrawing the latter, as shown in Fig. 5, to release the heel and to permit its removal and the insertion of a new heel as above described.l

It will be seen that the point to which the spurs 6 and heel seat support 58 are Withdrawn with reference to the top-lift rest 56,

and the consequent spacing of the heel clamping .elements when the heel clamp is released durlng the loading and unloading operation,

are determined by thelongitudinal position in the machine of the jackshaft section 36 and the assemblyI carried thereby. This position can be variedor adjusted, in order to adapt the machine to heels of different heights, by releasing the clamping bolt 40 which secures the hub '39 of the yoke 37 to the jack shaft section 36, moving said shaft section inwardly or outwardly and agam tlghtening said vclamping bolt. This adjustment .is permitted by the elongated form of the head 92 which enables said head vto cooperate with 89 in any position of adjust ment. f

The movable mounting of the sleeve 70 andparts carried thereby, together with the spring 8O which tends normally -to project said parts inwardly or toward the work, permits the heel seat support 58 to yield if necessa-ry (due to its angular position) when the heel breast is brought up to the breast gauge 7, but causes the vpositioning plate 59 to follow the movements of and remain in contact with the heel seat at all times during the insertion of the heel and the closing of the clamping devices, thereby avoiding any j of the toplift, from theline of pressure of the iron against the work, said arm 100 being pivoted at 101' between ears 102 on a U-4 -shaped or substantially semi-circular yoke 103. The iron 8 is formed at its outer side with a projection or shoulder 104, and' by reason of the above described ofset or eccentric pivoting of the iron holder 9, the normal pressure, exerted by means hereinafter described, ofthe iron against the edge of the toplift is given a component in the direction heightwise of the heel, whereby aportion of said normal pressu're is converted into an endwise pressureo'r thrust of the shoulder 104 against vthe outer face of the toplit to prevent pouting or cupping. The amount of this endwise ,component of the iron pressure is deinitely but adjustably fixed or determined by a spring 106 interposed between the'yoke 103 and an adjustable nut. 107 in threaded engagement with a rod 108 upon which said spring is mounted, said rod passing loosely through an opening v109 in said yoke and being secured at its inner end to the holder 9. The spring 106 tends to oppose the swinging of the holder about its pivot 101, and consequently to decrease the endwise component of the? pressure by a fixed amount depending upon the resistance of said spring, so that, by adjusting. the initial or normal compression of the spring by means of the nut 107, the endwise thrustloithe shoulder or projection 104 can be varied in accordance with the require- `sired, be backed by a threaded thrust rod 112 for assisting in ejecting the same from the holder when it is necessar to change' irons said thrust rod being pre erably com- A'pose of copper or similar material to assist in conducting the heat to the iron.

The yoke 103 Vis ivoted at its ends upon alined pivots 113 igs. 1, 2, 3, 4, 6 and 7) to the curved free end portion of a lever 115 l which constitutes the carrier by which the iron 8 is moved toward and from the work, said iron being secured to a shaft 1 16 journalled in bearings in the frame 20. The axis 'of the pivots 113 is substantially tangential to the toplift when the iron is in en agement therewith, andv substantially coinci ent with the bead-formin groove 114 (see Figs. 6 and l threaded engagement with 7) in the iron.

the yoke 103 is an adjusting screw 117 having a stem 153 which asses loosely through an opening 118 in the lever 115 and is providedat its outer end with a knurled operatlng head 119 between which and the lever 115 is interposed a compression spring 120 surrounding said stem. The screw 117 is provided with a fixed collar 121 normally held by the Spring 120 in engagement with the inner face of the lever'115, as shown in Fig. 6, said collar constituting a `stop for determining the normal position of the yoke 103 and iron 8 about the axis of the pivots 113. The arrangement is such that the normal position of the yoke 103 and the centre line of the'iron 8 are vsubstantially parallel to the lever 115, or substantially perpendicular to the axis of`oscillation of the jack and heel, this position being, however, capable of slight variation by adjustment of the screw 117. It will be understood that, for any particular work, an iron 8 will be chosen whose bed forming surface 122 (Fig. 8) conforms as nearly as may be to Athe desired form or curvature of the bed b ing longitudinally therethrough and having at is outer end a head 127, whereby the screw 124 may be turned to adjust the same in the lever 125 without disturbing the conv nection of the link 123 with the screw 117. The lever.125 is provided intermediate its ends with an arm 128 carrying at its end a cam roller 129 which cooperates with a cam projection 130 formed on the face of the cam 96. The roller 129 is normally urged toward the face of the cam 96 to the extent per- -mitted by the collar 121 b the spring120 acting through the screw 11 link 123, screw 124, and -lever 125. Periodic oscillation of the lever 125 by the cam projection 130 causes the yoke 103,l with the ironholder 9 and iron 8 to be rocked from the positionshown 1n Fig. 6 into that shown in Fig. 7, to cause the iron 8 to roll in the joint a between the heel and toplift as illustrated in detail in Fig. 9. The lost motion, indicated at 131 in Fig. 1, between the roller 129 and cam 96, and consequently the amplitude of the rocking move-- ment of the iron to roll in the joint, is'determined, in accordance with the requirements of the particular work, by the adjustment of.

the screw 124 in the lever 125. It will be A noted that the construction and arrangement are such that the adjustmentV last .referred to isentirely independent ofthe adjustment of the screw,117 in the yoke 103 so that neither is affected by the other, although both form parts of the same connection, since the adjustment of the screw 117 in the yoke 103 merely varies lthe position of said yoke with respect to said screw and does not vary the normal position of the screw itself, which is determined by engagement of the collar 121 with the lever115. y

The lever 115 and the parts carried thereby are normally urged toward the work to apply the requisite pressure of the iron 8 against the edge of the toplift by two-springs 132 (Figs. 1 and.2) and 113 (Figs. 1 and 3).- The spring 132 is a torsion spring surrounding the shaft 116 and secured at one end to the hub 134 of the lever 115. The opposite end of the spring 132 is, secured to the hub of a worm wheel 135 angularly adjustable on the shaft by a worm 136 journalled in an arm or bracket 137 carried by the inner bearing for the shaft 116, said worm being preferably provided with an operating crank 138. If desired, the hub of the worm wheel 135 may be provided with graduations cooperating with an index mark on the bracket 137 to indicate ythe adjustment.

The spring 133 is a tension spring 'connected at one end to a lever 115 adjacent the lower pivot 113 and at its opposite end to one arm of a bell crank 139 (Fig 3) pivoted at 140 to the frame 20 and having at its opposite end a cam roller 141 which engages the edge of a cam 142 on the cam shaft 32.

The spring 132 acts to cause the ironto exert a relatively light or normal pressure upon the work, the amount of which pressure is adjustable by means of the worm mechanism 135, 136. The spring 133, under the control of a bell crank 139, cam roller 141 and cam-142, operates to cause the iron to exert an increased or heavy pressure upon the work at certain times during the operation and to release said pressure when the iron is to be lifted away from the work inorder to permit the latter to be introduced and removed.

Pivotally mounted intermediate its ends on`the shaft 116 is a. lever 143 having at one end a cam roller 144 which engages the edge of a cam 145 on the cam. shaft 32. The opposite end of the lever 143 cooperates with an adjustable. abutment screw 146 in threaded engagement with a lug 147 on the lever 115.

lThe arrangement is such as topermit a certain amount of lost-motion between the lever 143 and screw 146, which amount may be' varied by adjustment of said screw, this lost-motion/leaving the lever 115 and parts carried thereby under the influence of the4 A warning bell 148 (Figs.2 and3) is prefer- -ably provided, said warning bell being sup- 151 to lift and release the clapper 149 and l cause the same to strike the bell 148 and thereby give a warning signal just prior to the interruption of the oscillation of the jack, the opening of the work clamps,.and the lifting of the iron from the work, in order that this operator ma at this time, be in readiness to remove t e finished heel and insert another.

In operation, the p-roper iron 8 having been inserted into the holder 9, the proper heel seat plate 59 having been applied to the holder 58, and the various adjustments above referred to having been made in ac'cordance with the requirements of the particular run or batch of work to be operated upon, the

machine is -started by operating the clutch, lever or handle 29 to cause the clutch 28 toV connect the gear 26 to the shaft 27. Rotation of the shaft 27 causes the ja'ck to be oscillated through the crank 42, pitman 45, segment 48, and pinion` 50 so long as the block 46 is locked in operative position by the dog 51. This oscillation is however periodically interrupted during oney rotation of the shaft 27 by engagement of the foot 4 of the dog 51 by the pin 55 on the controller gear 31, causing said dog to release the block 46 and permit said block to move idly in the slot 47. During the same period, the cam 96 acting through the lever 93, bell crank 89, and rod 84, operates to Open the work clamp, while the cam 145, actdescribed. It will/ be obvious however thatQ the precise number of rotations of the main shaft, the number of operative strokes, and the length of the loading and unloading pause may be varied in different machines to suit the convenience of the operator or .the requirements of the particular class of work for which the machine is designed.

The operator, after starting the machine 'by operation of the clutch lever 29, as above described, awaits the stroke of the warning bell, immediately after which the oscillation of the jack is stopped, the ironlifted away from the Work, and the work clamps released.

He thereupon inserts a heel with its attached toplit, the breast of the heel being placed against the auge 7 as shown in Fig. 45, and

the heel bemg centred on the plate 59 as shown in Fig. 14 by thesense of touch. The speed of operation of the machine is such as to give the operator suiiicient time to insert and position the heel during the idle rotation of the shaft 27. Immediatelythereafter the cam 96 restores the rod 84 to theinluence of the spring 85, causin the spurs 6 to engage and'embed themse ves in thematerial of the heel and to clamp the latter, with its attached toplift, against the toplift plate 56.

At the same time the cam 142 restores vthe le first six strokes the -cam roller 141 is in engagement with the high part of the cam 142 tensioning the spring 133 and causing'these strokes to be under heavy pressure. During the first stroke .the iron is in its normal position, as shown in Fi 6 and 8, this stroke -acting to Warm up t e wax with which the edge of the toplift has previously been treated and force the same into the joint a. During the second stroke the projection 130 on the cam 96 acts through the lever 125and link 123 to rock the yoke'113 and iron 198 into the 'position shown in Figs. 7 and 9 to roll in the joint a. After the completion of the second stroke the iron is restored to normal position and remains therein during the remainder of the cycleof the machine, the next four strokes being applied under heavy pressure with the iron in normal position as shown in Figs. 6 and 10 to m'old the edge of the: top- I lift and form the bed, bead and. panel thereon. Thereafter the low portion of the cam 142 is brought under the cam' roller 141, releasing the tension of the spring 133, and permi'tting the last two strokes to take place un' der the light pressure of the spring 132 to further set the edge and polish the same.- If desired, these twolight strokes may be omitted and the heavy setting strokes depended upon for the desired polishing effect. In the latter event, the tension of the spring 133 may i A, be releasedonl-y just prior to and during the idle stroke of themachine in order to decrease the pressure and thereby facilitate the lifting of the iron away from the work. At the completion of the next to the last operative stroke, the warning bell is sounded, and'upon thecompletion vof vthe last operative stroke y`the block 46 is again released2 from the seg- -ment 48, the iron lifted away from the work by the operation of the cam 145, and the work clamp opened by the `cam 96, thereby completfing the cycle of operations.
