T o a-ZZ 'whom t may concern:

Be it known that I, THOMAS LUND, a citizen of the United States, residing at Bew erly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Operating Upon Heels, of which the following descripj' tion, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for performing a plurality of operations upon heels. The invention is herein set forth by way of illustrationv with special referenceA to its applicability to compressing and breasting heels before they are attached to their shoes.

yUntil recently ithas been a universal practice in this country t0 breast the heels of shoes after they wereattached. Now, however, the practice of breasting heels before their attachment is becoming increasingly prevalent. Since practically all heels, the breasts of which are straight in the direction of the height of the heel, are compressed, it is advantageous to perform the lbreastingl operation in conjunction with the compressing operation. Accordingly, an

object of this invention is to provide a ma-` chine which will automatically compress and breast heels.

A feature of the invention consists in an organization comprising means for removing surplus material from a heel and compressing the heel, in combination with operating means to effect said treatments of the heel in succession. As herein shown the heel is operated upon at. successive stations, and means comprising a carrier, which may be intermittently rotatable, is operated in time relation to the said means to effect progression of the heel from one to the other of said means. As is usual in well-lmown heel compressing machines, as shown, the side dies of the relatively movable heel compress# ing means move vertically, and the toplift plate moves relatively to the compressing means to eject the heel or to cause it to be presented after compression above the'compressing means. To provide effective cooperation with the compressing mechanism, the illustrated heel transferring means,

vature to the transverse herein .shown as comprising co-operating lingers, is operated horizontally to takethe heel from the position in which it is presented by the toplift plate or ejector and to carry it to another position -for another opj eration. Preferably the transferring means presents the heel in predetermined operative relation to a second transferring means which is intermittently operated and may comprise,1 as shown herein, a rotatable or endless carrier having a series of pairs of jaws movable over a relatively fixed table upon which the heel is located by the first transferring means, a pair .of jaws being closed upon the heel and moved to another' position 1n operative relation to the breasting means which, as shown, comprises a re ciprocating knife acting in the direction of the height of the heel. i

A further feature of the invention consists in means for automatically locating a shoe bottom blank, or example an unattached heel, vin a predetermined position both longitudinally and rot-ationally, that is, aboutan axis lying within the body of the blank and perpendicular to its larger flat faces. Such means may consist in positioning members relatively power o erated in the operation of the machine an acting on the blank to determine both its longi tudinal position and orientation, that is, to effect a rotational movement of the blank in its own plane so as to locate its longitudinal median line in a predetermined direction. The blank is thus accurately located for a subsequent operation 0n the blank and in the exemplary embodiment of the invention illustrated a heel blank is positioned in a plane parallel to the plane of the table so that the breast face will be parallel with the knife edge. As shown herein, the positioning means comprises a striker which is actuated to engage the heel during operative movement of the out of operative position during the return movement of the knife. Preferably and as shown, the operation of the striker is controlled by the knife slide during the operative movement of the knife.

Another feature of the invention consists in means on the table corresponding in curcontour of the knife and xfeo-*operating with the knife to eiect a knife and which is held that disc =of a machine embodying shear cut upon the heel. Preferably said means is formed as a yblock which may be detached from the table when a differently curved knife is to be used and another yblock substituted therefor which corresponds to the curve of the new knife. Also, as shown, the block is arrangedfor adjust-ment transversely of the knife to enable its co-operating face to be set in accurate relation t0 the knife.

A further feature of the invention consists in novel mechanism for releasing the intermittently movable jaws to allow them toseize the heel or to open them to allow the heel to fall out after the breasting operation is completed. Preferably at the point where the jaws are opened to release the breasted heel the table that supports the heel is cut away to allow the heel to fall from the jaws.

Another feature of the invention consists in means for holding an nnattached heel in a fixed position and means for effecting two strokes of the breasting knife while the heel is so held. The first stroke breasts the heel by making a. roughing cut while the second stroke effects a finishing cut which Smooths the breast face.

These and other features of the invention, including .novel means for holding the heel, for controlling the opening and closing of the jaws, and various details of construction Aand combinations of'parts. will appear more fully from the following detailed description when read in connection with the accompanying drawings and willV be pointed out in the appended claims.

The heel compressing mechanism herein shown by way of illustration is similar to United States No. 1,172,471, granted February 22, 1916 on my application.'

.In Fig. 1 of the drawings the numeral 1 indicates the rigid frame of the machine on which the mechanism is supported. Vertical guideways are provided in the sides of the rigid frame and a head 2 is mounted therein for reciprocation. A suitable driving pulley and reducing mechanism are provided as shown in my prior patent above referred to, for transmitting motion to a gear 8 on a crank shaft 9. A link 10 is connected to the crank shaft 9 and also to' a toggle composed of members 11 and 12. The toggle member 11 is pivoted to `a rigid portion of the frame near its base and the other toggle member 12 is pivoted at 14 to the reciprocating head 2. The head carries a heel mold comprising a toplift plate 40, a breast die 21, andv laterally movable side compressing dies 22, as shown in Figs. 1 and 6.

In the upper part of the machine frame and alined with the recprocating head 2 is formed a rigid abutment 23 upon which is detachably mounted a heel seat die 25 in position to co-operate with the mold members carried by the head 2. The side compressing'dies rest on the top of the head 2 and are removably retained in slides 3() in order that other dies of different shapes may be substituted in changing from one style of heel to another. The side compressing dies 22 and breast plate 21 are actuated to close the mold and are thereafter opened to release the compressed heel by any desired mechanism, for instance, by normally inclined links 17 pivoted on opposite sides of the machine frame at 18, 18 as shown in Fig. 6.

The toplift plate 40 is provided with a downwardly extending stem 41 and mechanism is provided such, for instance, as that shown in my prior patent above referred to, for moving the toplift plate relativelyr to the mold, as shown in Fig. 1, so as always to present the heel with its lower or toplift face fiush with the upper surface of the mold.

The heels are fed to the compressor at the left of Fig. 1, each heel being positioned between fingers 31 (Fig. 6) with its breast face against a breast gage 33, the fingers being then in open position and the mold closed. As the head 2 moves downwardly and with it a frame 35 on which a lever 37 is carried. the lever 37 is actuated bv connections shown in Fig. 1 to move the fingers and heel over the now open mold, the fingers being separated to release the heel b v the action of a stationary cam 39 acting upon an jaw opening outward projection 43 of one of the lingers 31. This feeding mechanism is well-known 1n heel compressors and. is substantially as shown and described in my prior patent ed after compression by the toplift plate 40,

- will now be described and comprises mechanism best shown in Figs. 1 and 6.' As shown in Fig. 6, the mold slides 30, which are connected to the links 17 and through which pressure i's applied laterally to the mold members 22, 22, are provided `with grooves 32 preferably dovetailed in which are mounted sliding blocks 34. Fingers 36 are xpivoted to the blocks at 38 and are shaped as shown in Fig. 6. To each linger, at a4 point outside of the pivot 38, is'pivoted a member 42 by a vertical pivot 44. Links 46 are pivoted byA horizontal pivots 48 to the members 42, and means to be described is provided for moving the links 46 lengthwise to operate the lingers. The pivots 44, I48

rovide universal joint connections between the links 46 and the lingers 36. Movement of the links 46 toward the heel compressor first causes the fingers 36 to separate sulii-` ciently to clear the heel and the feed fingers 31 and then moves the slides 34 with the lingers 36 lengthwise of the vheel in the compressor until the fingers are behind the heel, the feed fingers 31 being at the same time retracted. The motion of the links 46 is then reversed, causing the ends 47 of the lingers' 36`to close against the heel. Lugs 50 on the fingers then engage the breast face of the heel and further movement of the links causes the fingers to transfer the heel from the heel compressor into a predetermined position upon a stationary table 52 which is located at the rear of the compressor.. To control the closing movement of the lingers, screws 54 are provided which are threaded through the members 42 and are adjusted to engage the outer ends of the lingers after a redetermined closing movement of the ngers has been effected by movement of the links 46 away from the compressor. The screws 54 may beso set that when the ends 47 of the fingers engage the sides ofthe heel being treated the screws l will limit further movement of the fingers and prevent lateral displacement of the heel by movement of one linger farther than the other. This construction minimizes mispositioning of the heel due to vspringing or lost motion of the parts', and if the heel is in such position that one linger engages it lirst that finger will shift the heel and position it properly in engagement with the other finger.

At their rear ends thelinks 46 are pivot ed at 58 in the slotted ends of a short cylindrical member 60 which is mounted to turn moves upwardly the rod 82 fingers.

in the lower end of any arm 62 and is held from longitudinal movement by a screw 64 engaging a groove Vformed in the member 60. at its upper end the arm 62 (Fig. 1) is integrally connected with a sleeve member 63 which is rotatably mounted on a shaft 65 journaled inra frame 66 bolted to the main frame 1. On thesleeve member 63 is another arm 68 slotted at 70 to receive a block 72 (Fig. 2) which is adjustable lengthwise of the slot by means of a tongue 74 attached tothe block and 'rotatably connected to an adjusting screw 76 threaded into the end of the arm 68. 'An eye-bolt 78 passes freely through the block 2 and is secured by a nut 80. A rod -82 (Fig. 1) extends through the eye'of the bolt 78 and at its lower end is pivotally connected at 84 with `the vertically movable head 2 of the compressor. spring 86 is arranged on the rod 82 between the eyebolt 78 anda stop nut 87 on the rod 82 and above the eye-bolt 78 is a stop nut 88. a stop screw 90 is threaded through a lug 92 on the frame 66 in position toV engage a stop projection 91 on the sleeve member 63 and limit upward movement of the arm 68 and inward movement of the arm 62.

The operation of the lingers 36 will now be understood by reference particularly to Fig. 1. It will be seen that as the head 2 will push upon the eye-bolt 78 throughthe spring 86- 68 and will rock the connected to the arm sleeve member 63, causing the arm 62 to move the links 46 to open the lingers and move them inwardly of the machine until the lugs 5() are located beyond the breast face of the, heel. This inner position is determined by the stop screw 90 which limits movement of the arm 62 by engaging the lug 91, the screw, of course, being readily adjustable to vary the inner position of the Further upward movement of the head 2 is permitted by compression of the spring 86. During downward movement of the head 2 no movement of the finger takes place until the head is nearthe lower limit of its movement and the ejector has removed a heel from the mold. During the lirst part of the downward movement of the head the compression of the spring 86 is released, and finally the space between the lstop nut 88 and the eye-bolt 78 is taken u allowing the nut 88 to engage the eye-boltgS and elfect a movement of thev arm 68 and arm 62 positively to withdraw the heel from the machine and to present it in a predetermined position upon the table 52. The head 2, of course, always returns to the same position and by 'adjusting the screw 76 the elfectivelength of the arm 68 may be varied to cause the heel to be presented on the table in predetermined but variable positions longitudinallv of the heel.

The table 52 has a central hub 98 (Fig.

which is rigidly clamped in' a boss 100 formed on a supplemental frame 102 bolted to the main frame 1 as shown. Arranged centrally of the hub 98 is a short shaft 104 on the upper end of which (Fig. 7) is secured a spider 106. Pivoted to the spider at 108 are four pairs of jaws 110 which constitute with the spider an endless carrier for the heels. The spider 106 is moved intermittently by mechanism to be described to present each pair of jaws in turn and permit them to dwell at successive stations A, B, C and D. The jaws of each pair are connected together for equal and opposite movement by interengaging teeth 112 and their closed position is adjustably determined by a screw 114 having a threaded mounting on the spider and engaging a pin on one of the jaws. The jaws are held toward each other by springs 116. It will be noted from Fig. 3 that each of the jaws is double, comprising a lower downwardly bent portion 111 which engages the surface of the table 52 and the portion 110 which is attached by screws to the lower jaw 111 and extends upwardly at a slight angle. The end portions 47 of the lingers 36, as they are moved to force `the heel on to thetahle between the pair of jaws located at station A, pass between the lower and upper portions of the jaws, the jaws separating if necessary against the spring 116 to permit the entrance of the heel to the heel engaging surfaces of the jaws and being preferably serrated or toothed securely to hold the heel in the position in which it is presented.

It has been found preferable to have the jaws open at the time the heel is presented between them since when the jaws are yieldingly held together during insertion of the heel there is apt to be unequal resistance offered by the 'jaws with a consequent shifting of the heel in the plane of its toplift from the position determined by the transferring fingers 36. Therefore, it is preferable to provide adjacent to station A means to engage a projection 206 on one of .the

ngers and cause the fingers to be opened while they are at rest at station A. This means comprises a cam member 51 (Figs. 6, 7 and 12) which is adjustably fixed to the mold slide by screws 55. The member has a downwardly and inwardly inclined face 53 which engages the projection 206 during the downward movement of the mold slide and causes the jaws to open prior to the insertion of the heel between them. Further movement of the slide carries thecam face k53 beyond the projection, allowing the jaws to close upon the heel. The jaws then start to move toward station B and the projection is out of the way of the cam 51 during the next upward movement of the mold slide.

The amount removed from the heel in the breasting operation will depend upon its longitudinal position in the jaws and it is consequently desirable to provide a gage or stop for limiting the longitudinal movementl of the heel. As shown, a plate 120 vis provided beneath each pair of jaws, the plate having a V-shaped portion to engage the rear end of theheel. Each plate is arranged to slide longitudinally of the heel and is held in adjusted position by a screw 122 engaging a slot in the spider 106 and threaded into the plate 120.

Since each of the gage plates 120 should of the spider shaft 104, it is desirable to provide means for adjusting the plates simultaneously and for locating them at equal distances from said center. As shown, a cam plate 113 is arranged beneath the spider for rotation relatively to the spider about the spider shaft 104. The cam plate 113 has four slots 119 extending from its edge inwardly at an angle and each slot is engaged by a pin 119X on the corresponding gage plate 120. By loosening the screws 122 and turning the cam 113 the gage Vplates 120 may be moved equally and simultaneously in either direction lengthwise of the jaws 110. For conveniently turning the cam 113 a pin 115 fixed thereto extends up through a slot 117 in the spider 106, the slot being curved concentrically with the shaft 104 and the pin 115 being used as a handle for turning the cam. By moving the cam 113 to its limit in one direction the open ends of the slots 119 will release the pins 119X and permit the plates 120 to be removed and others adapted for a different range of heel sizes to be substituted therefor.

Adjacent to the lower end of the spider shaft 104 is mounted` in the frame 102 and in a bracket 121', a shaft 123 having at its lower end a gear 124 meshing with a pinion 126 on a shaft 128 which is mounted in the frame 102. On the shaft 128 is a gear 130 meshing with a gear 132 on the shaft 9. The shaft 104 isvconneeted to the shaft 123 by intermittent gearing which may be of any suitable kind and is shown (Fig. 8) as of the Geneva type, the construction being such that a single rotation of the shaft 123 will cause a member 134 fixed to the shaft to impart a quarter revolution to a member 136 fixed to the shaft 104, it being understood that the movement imparted to the shaft 104 will take place during a relatively small part, for example 900,-of the rotation of the shaft 123 and that during the rest'of the rotation the member 136 will be locked from rotation and held in predetermined position with one pair of jaws 110 at the station A (Fig. 7) and another`pair at the station B of that figure. The rotation ratio of the gear 132 tothe gear 130 is 1 to 2 and the rotation ratio of the pinion 126 to the gear 124 is 2 to 1, and the relative timing of theA gearing set at the same distance from the centerproperly (xo-operate ment screw 167 Vmounted for` vertical reciprocation in the frame. An adjustable connecting rod 144 is pivoted to the knife slide at 146 and is carried at its lower end by a crank pin 148 on a crank 150 secured to the shaft 128 so that a vertical reciprooation will be imparted to the knife slide as the shaft 128' rotates. A knife 152 (Fig. 5) is clamped in the knife slide by a screw 154 and is adjustably held vertically by an abutment 156. When the slide descends the knife operates to remove material from the breast end of the heel and is arranged to co-operate with' the edge of the table upon which ,uponl the heel. As shown the dwell at station B covers one and a half rotations of the shaft 128 and hence the knife makes two strokes across the heel while the heel isat rest, the movement of the carrier occurring -in the interval between the time when the knife leaves a heel on its Second lup stroke and the time when the knife reaches another heel on its next downstroke.

In order that knives of different curvesY maybe used for breastingthe heels and m-ay co-operate with the table to effect a shear cut without changing the table, the portion of thetable upon which the -heel rests is made detachable as shown in Fig." 7. vThe table is provided with ledges 158, -158 upon which a block 160 rests with its upper surface fiush with the surface of the table. The front edge of the block 160 is contoured to correspond with the curve of the knife and a screw 162 is threaded through a lug on'- the table in position to engage the inner fend of the block 160 vto limit its inwardl movement and -to provide means for adjusting the block so that its front edge will with thel knife. The blockI preferably has tongues 161 on its sides which engage grooves in the table and the block 160 is held in the table by buttons 164 held to the table by screws 166 and arranged to engage the tongues 161 of the block 160. When the screws 166 are loosened the buttons 164 may be turned up against pins 165 (Fig. 7 )l to permit removal of the block 160. To take the thrust of the knifev against the block 16() an'abut- (Fig. 3) is threaded into the frame\102 beneath the block 160 and from the mold on to -tilting of the heel occurs as it ,the heel rests to effect a shearcut into contact with the heel and may be adjusted vertically so that its head will bear against the lower. face of the block and support it. f

While the lheel is being moved from its position over the mold to its position on the table the moldis moving downwardl and the plane of the to face of the mol is in the plane of the ta le only when the Amold is at the lower limit of its' movement. Therefore, tthe time when the heel p-asses the table the mold is somewhat above the table and a downward passes from the mold to thetable. If the jaws are not opened to receive theI heel when'the heel is pushed into |them they may not allow the lower face of the heel tocome in firm contact with the table. Hence it is desirable to provide meansoto press the heel firml down upon the table at the station A. Ff the jaws. are'open at' this time, as proposed above, it is desirable to"'provide 'means to hold'the heel pressed down against the table in the position given to it 'by' the fingers 36 when the jaws close upon the heel. Accordingly a pressure 168 is arranged for vertical reciprocation in the, frame 66in position to engage the heel with its lower outwardly bent end 169 and to press the heel firmly in contact with the table. Fixed at one end of the presser 168 -is a laterally extending arm 171 havin at its other end a sleeve 17 3 arranged to s ide on an operating rod 175 which is pivoted to the head the pin 84. On the rod 175 between the sleeve 173 and an adjusting nut 17,7'is a stiff spring 179 and on the rod 175 between the sleeve is a weaker spring 183. Extending upwardly as acontinuation of the presser 168 is a rod 185 guided in the frame 66 and having an adjustablesto collar 187 which engages the frame 66 to imit upward movement of the presser.` As'pthe head 2 moves upwardly the spring 183 acts upon the arm 171 to llft the .presser 168 as far as permitted by the .collar 187, and during downward movement of the head 2 the presser is moved pressure applied thereto through the, stili' spring'179. The timing is such that the presser is hfted during Ithe passage of the heel from station A to station B. o.

It is desirable to clamp'jtheheel against the table during the action ofthe knife and for this purpose a clamp 170 is provided 173 and a fixed collar 181 which has a downwardly ben-t end adapted 178 securedto the knife slide142. Duringl the downward movementof the knife the clamp 17 0 is brought into contact with the v the pivot 184 a spring 186 heel before the knife engages it and the friction means 176 then slips on the rod 172 during the cutting operation of the knife, the clamp being restored to its original position upon upward movement of the slide 142.

It may or heel is not positioned on the support 160 in proper position for a subsequent operation, for instance a heel for breasting, but is displaced slightly longitudinally or rotationally or both. Accordingly relatively power operated positioning members comprising the gage plate 120 and a member ,180 are provided which act on the blank and cooperate to determine both its longitudiinal position and its rotational position or orientation, that is, the direction of its longitudinal median line. As herein shown means is provided for insuring that the breast face of the heel will be positioned in proper relation to the breasting knife for the breasting operation. Usually this position will be with the breast face of the heel parallel to the edge of the knife. For this purpose the member 180 hereinafter called a striker is provided which is brought against the breast-end of the heel just prior to the breasting operation. Preferably the portion of the striker which engages the heel corresponds in shape to that of the compressed breast face of the heel and is arranged vertically so that it will strike the toplift portion only of the heel which portion has usually the more uniform shape in a compressed heel. It is essential only, however, that the striker engage the edge face of the blank or heel at points separated a substantial distance laterally of the blank or heel. If the heel in the jaws is improperly positioned the contact of the` striker 180 with the lower or toplift portion of the breast face will cause the heel to move rotationally in a horizontal `plane until its breast face is in the same direction as the striking face of the striker, and longitudinally until it is against .the gage plate 120, if it does not already engage it, the result being that the heel will then be positioned longitudinally so that it will be.

breasted to the proper length and will have its breast face in proper relation to the knife for the breasting operation.. This proper relation is usually, in treating heels of the broad, low type shown, such that the breast face of the heel is parallel to the plane of action of the knife, that is, with its longitudinal median line substantially perpendicular to the plane of the knife. The striker 180 is mounted on the lower end of a lever 182 having its upper end bent and pivoted at 184 to the frame 140. Below is provided `between the lever 182 and the frame 140 to move the striker toward the heel. A locksometimes happen that a blank.

links 188, 194 and the frame the breast end of the ing mechanism (Fig. 4) is provided for holding the striker normally away from the heel and comprises a link 188 pivoted to the frame 140 at 190 and having at its other end a notch adapted to engage a pin 192 on the lever 182 and hold the striker away from the heel in the position shown. A link 194 is pivoted at 196 to the frame 140 at one end and at its other end is connected by a link 198 to the link 188. The pivots 190, 196 are preferably provided with friction means to cause the links 188, 194 to remain in any position to which they are moved. These friction means may comprise lock washers 197 placed between the 140 on the pivot screws 190, 196 (Fig. 10). A detail of one of the washers 197 is shown in Fig. 11. The washer is split and the ends bent somewhat out of line, one end being provided with a sharp lip 199 which digs into the part engaged by it and causes the washer to move'frictionally against the part engaging its opposite side. The washer will yield somewhat to pressure of the screw which may be adjusted to secure the proper amount of friction. A roll 200 is arranged on the knife slide 142 in position to engage the link 194 when the slide is nearly in its uppermost position, the roll acting to lift the link 194, and, through the link 198, also the link 188 to release the end of thatlink from the pin 192 and permit movement of the striker toward the heel. This movement, however, is controlled by two cams 202, 204 fixed to the lever 182 and having edges which engage the roll 200. As the carrier and roll 200 move downwardly the roll will pass off the lower end of the cam 202 before the knife reaches the heel and allow the striker 180 to be actuated by the spring 186 against the heel to position it for the action of the knife. As the movement of the roll continues downwardly? it engages the cam 204 and pushes the lever 182 outwardly sufficiently to allow the link 188 to come again into locking engagement with the pin 192, then the roll 200 engages the link 188 and moves it against the friction holding means into locking position, the parts remaining in this position until the return movement of the roll 200 has been nearly completed.

As has been described, the knife makes two strokes while the heel is in the same position. The first cut removes material from heel by what may be called a roughing cut.

of the knife across the breast face of the heel smooths up the breast face and is re-l ferred to as a finishing cut.

Upon the next intermittent partial rotation of the spider 106 the heel will be carried to station Gand a new heel brought into station B for the breasting operation. Upon The second passage fixed to the table 52l and adapted to be en- 'an opening in gaged by the projection 206 temporarily to' arrest movement of that jaw.y By reason of the inter-connection V112 between`l the jaws, the opposite jaw will be correspondingly ,opened and the heel allowed to drop through Where suitable means may be provided to receive the heels. Upon the next movement of the spider 106 the projection 206 will ride off the member 208 and allow the .jaws to be closed by ,their spring 116 before they reach A station A again.

It is desirable so that it will yield after suflicient pressure has been applied to the projection 206 to open the jaws and also to provide means to enable the projection to pass the member 208 without obstruction if the spider is turned back' wardly, as is sometimes necessary, as for in-r stance, when an abnormally thick heel is presented to the compressor and the machine sticks and fails to go over. It is then necessary to throw 0E the power and turn the machine backwardly .by hand to enable the heel to be removed. Since the spider 106 is geared to the compressor, the spider I. also must be turned backwardly and the jaw projection 206 will engage the member 208, and either that or the jaw be bent or broken if the member is not arranged to permit free rearward movement of lthe projection 206 past it. TheV member 208 is, therefore, pivoted to'turn a partial rotation on a pin 210 carried by a block 212 which rests on a ledge 214 formed on a supporting 'member 216 which is adjustablysecured to the lower face of the table'by screws 220. The screws pass through slots in the member v216which are arranged in thegeneral direction of the edge of the table so that the member 216 may be set in various positions alongthe edge of the table to vary the point in the rotation of the spider at which the jaws will be opened. The block 212 has a stem 222 about which is a spring 224 arranged to holdfthe A block v212 inwardly against the supporting rection and the member is normally held at this-limit by a spring 228 connected between the member 208 and the'supporting member 216. `I fithe spider 106 is turned backwardly the projection 206 of the jaw will strike a face 230,0n the member 208 and the member will turn on its pin 210 against the tension the table at the station Dr vof the spring 228 andr allow the projection 206 to pass without bending or breaking the J Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
