MACHINE FOR INSERTING FASTENING-S.

Application filed July 5, 1917.

u all whom it may concern:

Be it known that I, LOUIS A. CASGRAIN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Inserting F astenings, of which the following description, in connection with the accompanying drawing, is a specification, like reference characters on the drawings indicating like parts in the several figures.

The invention hereinafter described rc lates to machines for operating on boots and shoes and, while it comprehends principles of construction and operation especially applicable to the insertion of fastenings in the heels of boots and shoes, it is applicable to fastening-inserting machines in general and to shoe making machines of other types.

The term fastening is herein used for the sake of brevity, in its broad and general sense, and includes devices and means for uniting either temporarily or permanently the parts into which they are inserted or for purposes of ornamentation or resisting wear. In the following exposition of the invention it will be described in (onnection with a machine for inserting fastenings into the heels of boots and shoes, such, for instance, as that described in the patent to Casgrain, No. 1,053,479, but it is to be understood vthat the present invention is not limited to machines of the character disclosed by said atent.

It is .requently desirable when a tool or toolsis caused to operate on a shoe that the oints of operation of the tool on the work be spaced at uniform distances from each other. For example, when a series of fastenings is inserted into a boot or shoe part, such, for instance, as the heel of a shoe by fastening inserting tools or instrumentalities the fastenings should preferably be uniformly spaced with relation to each other, and the same uniformity of spaced relation should be maintained in heels of different dimensions. Where such series of fastenings is to be arrangedin a curved line, such, for instance, as long or parallel to the contouredge of a heel, difficulty is expej'igepced inmaintaining the desired uniform; {1n the spaces between adjhacent fasteningsjw en the dimensions of the .001s vary, becallw the angular feed ,movement of the work appropri- Specification of Letters Patent.

Serial No. 178,628.

ate to space the fastenings properly in a heel of one dimension will not be suited to maintain the same s aced relation of fastenings in a heel of di erent dimension.

An important feature of the present invention consists in means for feeding the work support variable angular amounts determined by a dimension of the work sup ported by it. This feature of the invention may be variously embodied. As illustrated, it is embodied in an organization comprising a work support and a gage for positioning the work, together with a feeding means for the work support constructed and arran ed to permit the operative relation of the wor support and feeding means to be vawork.

Another important feature of the invention consists in means for preventing movement of the work support between feed movements regardless of the amplitude of the feed movements. In the illustrated embodiment of the invention this is effected by a clamp or holder, which, during feed movements, is inoperative, but between feed movements is automatically actuated to clamp the work support and hold it from accidental movement.

During the operation of the machine, it is also desirable that the heel or other part of the shoe being operated upon be held firmly against the gage or other device which positions the shoe relatively to the operating tool or tools, and yet that the shoe be readily movable toward and from the age when the machine is at rest to ermit the work to be movedinto and out of operative relation to the operating mechanism. A further important feature of the invention consists in a work support freely movable to place the work against the gage while the machine is at rest and means acting automatically when the machine is started to force the work yieldingly against the gage. As shown herein, this feature is embodied in a spring connection between the shoe support and means 0 erative upon starting the machine to place t e spring under tension.

Since economic production renders it desirable that the operation on the shoe be carried on with as little interruption as possible consistent with a proper supply of work by the attendant, in accordance with another Cir feature of the present invention, the illustrated machine is provided with a shoe support comprising a carrying plate or member operatively associated with a machine part and a plurality of jacks of novel construction which may be readily applied singly to the carrying plate or member, so that while one shoe is being operated upon the attendant may be jacking another shoe ready to be seen red to the carrying plate or member as soon as the current operations have been completed.

It is furthermore important that the points of operation be arranged at uniform distances from the edge of the heel or shoe part upon which operations are being performed and, to insure this relation of the operating means and the edge of the work, another feature of the invention consists in novel means for guiding the work support during its feed movements in a path substantially similar to the contour of the heel or other shoe part.

Where the shoe support, as in the illustratcd form of the invention, is not raised and held raised during the insertion of a fastening and then lowered to permit feed 7 of the work, it is desirable to adjust the shoe on the jack in such position that, when the jacked shoe is transferred to the carrying )late or member, the tread surface of the heel may pass beneath the foot plate and yet be in such close proximity thereto that, when the foot plate is depressed during the insertion of a fastenin it will firmly engage and press upon t e tread surface of the heel. The present invention comprises also as one of its important features a jack of novel construction and means for determining the position of the shoe on the jack so that the tread surface of the heel may pass beneath the foot plate when the jacked shoe is transferred to the carrying plate or member.

The invention comprises other features which, in addition to those above referredto, will be fully described in connection with the accompanying drawin s, which show one good, practical form 0 means for carrying the several" features of the invention into effect, and the several features of the invention will then be definitely set forth in the claims.

Fig. 10 is a view similar to that of Fig. 9, but showing some of the parts in section and others broken away to disclose the structure beyond.

A .base or standard 1 of suitable character supports a head 2 in which is suitably mounted a main driving shaft 3. Upon the main driving shaft 3 are the fast and loose pulleys 4; and 5 which may be connected by suitable means such as a belt, to any desired source of power. \Vhcn the machine is in use, the belt will be shifted from the loose pulley 5 to the fast pulley 4, so that the main driving shaft 3 will be continuously rotated. Secured to the main driving shaft 3 is a cam disk 6, the cam groove of which is engaged by a pin or roll carried by an arm 7 suitably mounted to rock on the head frame. The head frame 2 carries the foot plate 8 which, during the insertion of a fastening into the work, is lowered to rest upon the work and impart some degree of pressure thereto. An edge gage 9 18 carried by the head frame and serves to position the work relatively to the fastening-inserting mechanism by engagement with the contour surface of the work. In case the fastenings are to be inserted into a. heel, the edge gage 9 will contact with the contour surface of the heel, and serve to guide the heel as the latter is moved or fed along the edge gage to position the work for the insertion of fastenin s in succession. The parts so far describe as well as the means for operating on the Work to insert fastenings therein may be substantially of the same character and construction as those disclosed in the Casgrain Patent, No. 1,053,479. The machine of the said patent makes and inserts the fastenings; but it will be understood that the present invention, while applicable to a machine of this type, is equally applicable to machines which insert previouslyformed fastenin s.

Rising from t e base or standard 1 is a supportll) havin arms 11 for sustaining a table.,12 on which is adapted to rest the carryingtp ate or member 13 of the work sup ort. "When the work is placed upon the wor support, the construction of which will be hereinafter described, it is desirable that the work support be movable to place the edge of the work or the heel against the back gage and in operative relation with the fasteningdnserting mechanism, and that after the work has been placed in such operative position relative to the fasteninginserting mechanism, that it be given a step by-step feed movement for the insertion of fastenings in desired design into the work. Obviously, the size or contour shape of a heel will determine the position to which the work is moved to bring it into operative relation with the fastening-inserting mechanism; and since the size and contour of heels differ, the step-by-step feed movements given to the work support which will be suitable for one character or size of heel will be unsuitable for another size or character of heel. The present invention, therefore. contemplates that the angular step-bystcp movements imparted to the work shall be variable in amounts as determined by a dimension of the work in order to insure that similar intervals be maintained between the tastenings when driven into heels of different or contours.

The feeding means for imparting the step by-step movement to the work support may he variously contrived. but in the present instance of the invention it comprises an actuating arm i lpivotally mounted at l5 to a fixed part of the machine frame and connected by a link 16 to an arm l? extending from a roclcsha it 18 supported in suitable hearings if) sustained upon the head frame oi the machine, and actuated from the main driving shaft 3 through suitable connections such. for instance. as the arm 20 secured to the rock-shaft i8 and connected at its free end to the rod iii. The rod at its upper portion is connected at :22 to a rocker arm 23 pivoted on a supplemental shaft 24: and having at its upper end a pin or roll 25 engaging a suitable ram groove 26 in a cam secured to the main shaft. In the present instance of the invention the cam groove 26 is formed in the face of the fast pulley 4. From the constructiondescribed it will be appaivnt that when the main driving shaft 31 is operated, the arm l4 of the feed mechanism will be continuously operated or rccip rocated on its pivotal mounting 1:3.

llxtending downwardly from the carrying plate or member 13 oi the work support is the spacer 537. Fig. 3. having at its lower portion and spaced some distance from the carrying plate or member 13. the flange 28. The arm 14- of the feeding means is bifurcated at as indicated in Fig. 3 and the flange 2 extends into the bifurcated portion of the arm, the construction being such that should the carrying plate or mem ber 13 be moved bodily relative to the feeding means, the position of the flange 28 within the bifurcated portion of the arm let will be changed and the degree of change will be dependent upon the amount of relative movement given to the carrying plate or member 13. As hereinbefore noted, the carrying plate or member 13 is a part of the work support on which is mounted the work into which fastenings are to be illserted; consequently, when the carrying plate or hub 13 with the work mounted thereon is moved relative to the feeding means or the arm 14 to place the contour edge of the work against the edge gage, the flange 28 of the carrying plate or member 13 will be moved more or less into the bifurcated portion 29 of the arm 14.

In order that the actuating arm 14 of the feeding means may be operatively connected to the flange 28 of the carrying plate or member 13 as the actuating arm 14 makes its active stroke and be released from such operative connection when the actuating arm makes its inactive stroke, the present invention provides means for effecting operative relation of the actuating arm with the flange 28 only when said actuating arm is making its active stroke. This feature of the invention may obviously be carried into effect by various detail forms of means, but in the present instance or the invention, a wedge carrying plate 30 is mounted to rock upon the pivot, 15. Fig. 3. and carries a wedge portion 31. on which rests a pin 32 passing through the perforation in the actuating arm '14 and adapted to engage one side of the flange 28 of the Work carrying plate or member 13 when the wedge plate 30 is moved to cause a high part of the wedge 31 to pass beneath the pin 32. The upper portion of the actuating arm 14 may be provided with a friction piece 33 between which and the upper end of the pin 32 the flange 28 may be clamped when the wedge plate 30 is properly actuated. In order further to insure an equal spacing of the fastenings regardless of variations in the sizes of the heels, the Friction piece 553 and pin 32 are disposed to engage the flange 30 at the end of their feeding movements at points substantially in line with the fastening driver.

The wedge plate 30 is connected by a link 34 to a block 33 nmvablc in a slot 36 formed in the upper portion oi an actuating arm 37 projecting from the rock shaft 38. Fig. at.

The rock shaft 39 may be actuated tronrany suitabie source of power but in the present instance or the invention it is provided with an arm Fig. l. to the end of which is pivotally connected the link it) which at its upper end is pivoted to a rocker 41 mounted to rock upon the stud or shaft .24, Fig. l, and carrying a pin or roller 42 Fig. 5. traveling in the cam groove 43 of a cairn-i4 secured to the main shaft, the construction being such that as the main driving shaft 3 is continuously rotated, the actuating arm ii of the feeding means and wedge carrying arm will be reciprocated.

It is desirable, however, while the machine is running idly. that the work support be not given its feeding movements; and to this end the wedge plate 30, when the machine is running idly, is so related to its actuating means that it will not clamp the flange of the carrying plate or member 13' to the actuating member 14 except when the fastenings are to be driven. In the present instance of the invention the block 35, Fig. is connected by the links to the arm 46 projecting from a rockshaft 47. The rock shaft 47 has secured thereto an arm i8 to which is pivotally connected the link 19. Fig. 4. the upper end of said link, Fig. 1. being connected to the bell crank le er 50 pivoted on the machine head at 51 and carrying a roll or pin 52 engaging the cam groove 53 in the cam disk 54, the construction being such that should the high part of the cam groove 53 engage the pin or roll 5'3 of the bell crank 50, the link 49 will be depressed and be held depressed so long as the nin or roll .32 is in engagement with the. high part of the cam. to thereby move the block 35 upwardly in the slot 36, Fig. 4. and so relate the wedge plate to the pin 32 as that upon rocking movement of the shafts 18 and 38. in the manner hereinbet'ore described. the wedge ill will cause the pin 32 to clamp the flange 28 of the carrying plate or member of the. work support and effect a feed movement thereof.

As fully described in the patent to (asgrain, No. 1.053.479. hereinbefore referred to. the fastening-inserting operations of the machine are under control of the two armed lever Fig. l, the arm 56 of said lever being normally in engagement with the toe or projection .57 described in said patent when the machine is not driving the fastening. V hen the fa tening-driving operation is to be started, the trcadle 58 is depressed and through the trcadle rod 59 connected at its upper portion at 6 to tl arm 61. projecting from the two armed lever 551 throws the arm 56 from under the finger or projection 57 and permits said finger or projection to move 1250 until it contacts with and is stopped by the hook ('12 on the other arm of the lever substantially as pointed out and fully described in said (lasgrain patent. When the projection or tinger 57 moves 18!). as stated. the high portion of the ram 5 will ride under the pin or roller 52 of the bell crank 5t) and cause a depression of the link 49 and corresporuling lifting movement to be imparted to the block whereupon the functional operation of the feeding means will he inaugurated.

When a shoe is placed upon the work support it is desirable that the work support be freely movable to place the edge contour of the work against the edge gage. The movement thus imparted to the work sup port will vary. of course, in accordance with the size or dimension of the work itself. After the work has been placed upon the edge gage, however. it is desirable that the feeding movements of the Work support be made in a path substantially the same as the contour of the work. and that during such movement the work be held with yield ing pressure against the edge gage.

To these ends. the present invention contemplates means for permitting free movement of the work support to place the work against the edge gage while the machine is at rest, and upon starting the fastening-inserting operation, to place the work support under yielding tension against the edge gage. The means to these ends may be variously contrived, but in the present instance of the invention the work carrying plate or member 13 is provided on its under surface with a groove 63 which is shaped substantial iv in accordance with the general contour outline of the heel of a shoe. This groove (33 may extend all the way about the end portions of the work carrying plate 13 in which case each end portion of the groove 63 will conform to the general outline contour of a shoe, so that. regardless of which end portion of the plate presented to the operative, a jacked shoe may be secured to the carrying plate ready for the fasteninginscrting operations. as will more fully appear.

'ihe groove 63 of the carrying plate 13 is engage-:1 with guiding and holding means which. in the present instance of the invention. comprise the pins or rolls (3%. Fig. 2. 'l'hrse pins or rolls are carried by a slide 65 mounted in suitable ways in the table 12. and the slide 65 has secured thereto one end of a spring (56. the other end whereof is connected to the upper end of a rocker arm 67 secured to the rock shaft 68. Fig. 3. Froni the construction described it will be apparent that if the rock shaft 68 is free. the slide 65 and perforce, the work carrying plate 13 may be moved bodily to carry the work mounted on the work support toward and from the edge gage. If. however, the rock shaft 68 be turned clockwise, Fig. 3. to place the spring 66 under tension. and hen locked, the work placed against the edge gage will be held yieldingl v against said edge gage during subsequent feeding operations of the work support.

The rock shaft 68, Figs.4 and 8,is suitably mounted in bearing arms 69 extending downwardly from the table 12. The rock shaft 68 has secured thereto the toothed segment 70 adapted to be actuated by a pawl 71 mounted on a pawl carrier 72, Fig. 8, loosely supported on the shaft 68 by the hub or collar 73. Extending from the sleeve 73 is an arm 74 to which is connected at 75 the upper portion of a link T6, the lower end portion of which is connected at 77. Fig. 4-. with an arm 78 extending from the rock shaft 47. the construction being such that when the rock shaft 47 is actuated by depression of the rod 49 as the machine is set in operation for the insertion of fastenings, the pawl 71 will engage the teeth of the toothed segment and rock shaft 68 to place the spring 66 under tension and hold the work silpport with the 'work yicldingly pressed against the edge In order that the degree of tension to be placed upon the spring 66 may be readily adjusted, there is loosely mounted upon the shaft (38 an arm 79. Fig. 8, which carries a plate 80 adapted to be positioned at different points along the toothed segment to determine the engagement and disengagement of the pawl with the toothed segment. This adjustment may be effected in any suitable manner, as for instance, by a rod 81 secured at one end to the arm 79 and at the other end provided with the slotted member 82 adapted to be held in adjusted position by means such as the bolt 83. From the construction thus far described it will be apparent that when the machine is at rest, that is, when the fastenings are not being inserted, the slide 65 and perforce, the work support, is freely movable to enable the work support to be manipulated and adjusted in position to place the edge of the work against the edge gage, such movement also serving to adjust the operative relation of the feeding means and work support in accordance with the size of the work. l-Vhen, however, the machine starts into operation for the insertion of fastenings, the depression of the rod 49 causes the pawl 71 to actuate the toothed se 'ment 70 and the rock shaft (38 clockwise, l ig. 3, and place the spring 66 under suitable tension for holding the work against the edge gage. A suitable spring 84, Fig. 3, may be carried by the pawl carrier 72 and act upon the pawl 71 to hold it in operative position.

After each feed movement of the work support, it is desirable that the work support be held from accidental movement as the feeding means moves on its idle stroke. The invention contemplates in this respect, means for preventing movement of the work support during such time, said means in the present instance of the invention comprising a clamp 85, Fig. 3, pivotally mounted at 86 upon the slide 65 and carrying a roll 87 which rides upon the top surface of a cam slide 88. The cam slide 88 is guided for movement transversely of the slide 65 in suitable ways 89 formed upon the slide 65, and is connected by an actuating link 90 with a rocker arm 91 pivotally mounted in a suitable bracket 92 projecting from the table 12. The lower portion 93 of the rocker arm 91 engages the upper end of an arm 94 secured to the rock shaft 38, the construction being such that as the rock shaft is rocked to release the work support from control of the feeding means, the cam slide is moved beneath the clamp 85 to cause its end portion which overlaps the work carrying plate 13 to press upon and lock the said plate from movement.

W'hile placing a jacked shoe upon the work carrying plate or member 13. and while removing a jack therefrom, it is also desirable that the work carrying plate or member i3 be locked from n'lovement. and this is effected in the l)l'(:=0llli instance of the invention by trundle controlled means comprising a rorkel' 95, Fig. 3, connected to the treadle rod 96 which is adapted to be actu ated by the trcadle 97. Rising from the rocker is a finger 98, the upper end portion of which is adapted to engage a toe or finger 99 extending downwardly from the hub 100 mounted to rock in suitable bearings 101 on the table 12. The hub 100 has extending therefrom a clamp actuating arm 102, the end 103 of which is adapted to extend beneath the rearwardly-projecting portion of the clamp 85, Fig. 3, the construction being such that upon depression of the treadle 9? the rocker 95 will be actuated to cause the clamp 85 to clamp the work carrying plate and hold it from accidental movement while the jacks are being changed 100 on the plate. Upon release of the trcadle 97 after the jacks have been changed, the work support is freed to be moved by the attendant to place the work on the worksupport against the edge gage.

When the machine is operating for the insertion of fastenings, and the lock 35 is raised in the slot 36 of the arm 37 to effect operative relation of the wedge plate 30 and actuating arm 14 of the feeding means, it is desirable that the block 35 be locked in such position so long as the insertion of fastenings continues, and to this end the rock shaft 47 has secured thereto a locking finger 104, Fig. l, which is adapted to engage the outer edge portion of a lug 105 mounted on the starting rod 59 and normally held in raised position by a spring 106, one end of which rests upon a clamp 107 secured to the starting rod and tlie other end against the lug 105. \Vhen the treadle is depressed for starting the fastening-inserting operation, the locking finger .104 will engage the outer end portion of the lug 105 and lock the block 35 in raised position; but when the trcadle is released, the lug 105 will be lowered to disengage the locking finger 104 to permit the block 35 to move downwardly in the slot 36 into inoperative position.

Where the shoe support is not raised for the insertion of fastenings and then lowered to permit the work to be fed, as in the illustrated form of the present invention, it is desirable to adjust the shoe on its support in such position that when it is opera-tively related to the fastening-inserting mechanism, the foot plate may engage the surface into which the fastcnings are to be inserted. In these respects the present invention eontemplates a novel form of jack and means for determining the jacked position of the shoe relative to the foot plate before the jacked shoe is placed in operative relation with the fastening-inserting mechanism.

The jack comprises a base portion 108, Figs. 9 and 10, which is adapted to be moved over the top surface of the work carrying plate or member 13 which normally maintains its operative relation with the machine elements. Risin from the base 108 of the jack, is the be low support 109 in which is the longitudinally movable jack post 110. Mounted in the top of the jack post is the rocker 111 from which extends the last pin 112, a light spring 113 acting on the rocker 111 to maintain it normally in upright position. A spring 114 normall acts upon the jack post 110 tending to 1i 1; it. This spring may be of any usual character and as shown is of the spiral form, one end of which is seated at the lower portion of the support 109 and the upper end against a block 115 mounted in the top portion of the jack post. The jack post is guided in its movements in the support 109 by a pin 116 which passes through. the sup port 109 and enters an elongated slot in the jack post as indicated in Fig. 10. The jack post has a series of teeth 117 which are adapted to coact with corresponding teeth on a block 118 seated in a recess 119 formed in the support 109, said block being normally under the action of a spring 120.

Extending from the base 108 of the jack is a sleeve 121 from which projects a rod 122 having adjustably mounted thereon the sleeve 123 carrying the toe support. In the present instance of the invention the'sleeve has projecting upwardly therefrom the exteriorly-threaded hollow post 124 in the hollow portion of which is received the rod 125 extending downwardly from the upper portion 126 of the toe support. Surrounding the exteriorly threaded hollow post 124 is the interiorly threaded sleeve 127. The upper portion of the sleeve 127 has a series of notches 128 with any one of which a pin 129 carried by the rod 125 or the head of the toe support may engage, the construction being such that upon rotation of the sleeve 127 the toe support may be raised or lowered to adjust properly the height of the toe support for contact of the work being treated. The notches 128 in the sleeve have rounded side portions so that while the pin 129 serves to look the sleeve from rotation under any usual disturbing cause, it permits the sleeve to be rotated on the application of suitable force. The toe support may be properly faced with a suitable pad or other yielding substance 130 to prevent injury to the toe portion of the shoe, and the rod 125 which is secured to the toe support as by means of the pin 131., is prevented from rotating in the sleeve 124 by a pin and slot connection.

Secured to the rod 122 is a clamp 132 having secured thereto the arms 1315 provided with notches 134 adapted to engage under lugs 135 secured to and projecting upwardly from the carrying plate or member 13. In order that the jack may be readily applied to and disconnected from the carrying plate 13, the arms 133, of which there may be two, one at each side of the jack, are preferably formed yielding, but of suflicient stiffness to hold the jack in proper operative .osition on the carrying plate.

Mounte for rocking movement in suit able bearings formed in the base portion of the jack is a shaft 136 extending transversely thereof and havin secured thereto the block supporting mem er 137, the portion 138 of which is connected as by the rounded portion 139 with the block 118, the construction being such that the spring 120 acting on the block 118 will normally force the block to present its teeth into locking engagement with the teeth 117 on the jack post. to thereby hold the jam: post in raised position; but should the shaft 136 be rocked clockwise, Fig. 10, such rockin movement will carry the block 118 to the right out of looking engagement with the teeth 117 of the jack post, thereby permitting the jack post to be controlled by the spring 114 alone.

Loosely mounted upon the rock shaft 136 are the side arms 140 of the heel seat clamping member 141, the upper portions 142 of which are adapted to receive between them the rear portion of the shoe. substantially as indicated in Figs. 9 and 10. The inner surfaces of the upper portions 142 of the clamping member may be suitably lined with a non-abrasive material 143 to prevent injury to the upper of the shoe.

Mounted for longitudinal movement in the heel seat clamping member 141 is the plunger 144- which is normally under the influence of a spring 14.5 tending to move the plunger downwardly anil its lower end 146 into contact with a ledge or projection 147 extending from the base portion of the ack.

Pivotally mounted on the heel seat clamping member 141 is a holding pawl 148 normallyunder the influence of a spring 149 tending to move the upper end 150 of the pawl into engagement with a recess 151 formed in the plunger 144, and its lower hooked end 152 into engagement with the under surface of the locking shoulder 153 formed on the base of the jack.

Mounted on the end portions of the rock shaft 136 are the disks 154, Fig. 9, provided with the notches 155 in which ride the pins 156 carried by the arms 140 of the heel seat clamping member. These notches 155 are sufficiently large to permit considerable movement of the heel seat clamping member about the axis of the shaft 136 without the pins 156 engaging the shoulders at the end portions of the notches; but when the heel seat clamping member is moved into its fully-inoperative position as indicated by the dotted lines in Fig. 9, the pins 156 meet the shoulders of the notches 155 and turn the shaft 136 clockwise, Figs. 9 and 10, thereby withdrawing the locking block 118 from its engagement with the teeth 117 of the jack post, and freeing the latter. When the heel seat member has thus been moved to its fully-inoperative position, it is desirable that it he held in such position while the shoe is being placed upon the jack post. To this end the hook 152 of the holding pawl 148 engages beneath the shoulder 153 formed on the base of the jack and the end 150 thereof engages in the notch 151 of the plunger 144. thus relieving the heel seat clamping member from the full stress of the spring 145 and maintaining said member in fullyinoperative or dotted line position as indirated in Fig. 2). The formation of the holding pawl and the notch 151. and locking shoulder 153 are such that by slight effort the heel seat clamping member may be moved from its inoperative or dotted line position, Fig. 9, to its full line position.

Iivotally mounted upon the heel seat clamping member at 157 is a toggle jacking member. in the present instance of the invention this comprises a hand grip 158 having pivoted thereto at 159 a jacking pawl [60 normally under the influence of a light spring 161. The plunger 1.44 is provided with a series of teeth 162 adapted to be engaged by the jacking pawl 160, the construction being such that when the hand grip 158 is moved to the right, or contra-clockwise, about its pivotal mounting 157, Fig. 10, the jacking pawl 160 removed from the teeth 162 and the heel seat clamping member may be moved readily into its full inoperative position. W hen a. shoe has been placed upon the last pin with its toe resting upon the toe rest, and it is to he jacked, the heel seat clamping member is moved from the dotted to the full line position, Figs. 9 and 10, to cause the side members 142 to embrace the rear portion of the shoe between them and force the toe of the shoe upon the toe rest. The hand grip 158 is then moved to the left or clockwise about its pivotal mounting 157, whereupon the end of the pawl 160 engages the teeth 162 of the plunger 144 and imparts to the heel seat clamping member a further jacking movement by the toggle action of the jacking pawl 160 and hand grip 158.

In order that the shoe may be jacked upon its support at a proper height to be placed upon the work carrying plate with the tread surface of the heel beneath the foot plate of the machine, the present invention contemplates a gage for determining the height oi the shoe on the jack suitable to enable the shoe to be placed in operative position. This gage, in the present instance of the invention, comprises an arm 163 mounted on the upper end of a rod 164 adjustably carried by a block 165 formed on or secured to the side table 166. The gage 163 may be adjusted with respect to the surface of the side table 166 such that the distance between the surface of the table and the surface of the g: ;e corresponds to the distance between the surface of the work carrying plate 13 and the foot plate of the machine; consequently when a shoe is placed upon the jack, which is done when the heel seat clamping member is in full inoperative position and the jack post 110 is unlocked, the tread surface of the heel of the shoe mounted upon the last pin of the jack post may be permitted to rise. under the action of the spring 114 until the tread surface of the heel meets the gage 163. whereupon the heel seat clamping men1- Iver will he turned from its full inoperative position. dotted lines Fig. 9, into its full line o jacking position, at which time movement of the hand grip 158 clockwise about its pivotal mounting 157 imparts a toggle action to the pawl 160 to give an additional jacking movement; to the heel seat clamping member to securely jack the shoe.

While the attendant is jacking a shoe as above explained. the machine may be inserting fastenings in a shoe supported by another jack secured to the work carrying plate; and when the .lastening-inserting operation has been completed, the attendant may readily detach the jack carrying the shoe having the fastenings inserted therein from the work carrying plate and substitute therefor the shoe which he has just jacked. if the jack holding the freshly jacked shoe werepresented to the machine in the same relation to the table 13 as the jack supporting the finished shoe, the contour edge of the heel of the shoe in the continued operation of the machine, would be carried away from the fastening inserting instrumentalities, inasmuch as the table 13 is rotated continuously in the same direction. Consequently, it is contemplated that the jacks and the shoes supported thereby will be presented to the table 13 in alternately reversed relations, and since the rolls 64 are disposed substantially in the middle of the relatively straight portions of the groove 63 at the sides of the table 13 at the end of each fastening inserting operation on a shoe a heel will thus be operatively presented to the fastening inserting instrumentalities during substantially every part of the cycle of movement of the table 13.
