36 Claims.

This invention relates to machines for applying pressure to shoe bottoms and is herein illustrated -as embodied in a cement sole attaching machine of the type disclosedin Letters Patent of the.- United States No. 2,047,185, granted July l., 1936, upon an application led in the name of Milton H. Ballard et al.

The-machine of the patent mentioned is provided withra plurality ofpads for receiving soles and shoes, these pads being arranged to be presented successively at an operating station. Associated witheach pad are sole and shoe positioning members or gages for relatively locating the soles and shoes on the pad, these sole and shoe gagesbeing moved yieldingly toward a sole on the pad and the sole gages, after finding and contacting with the edge face of the sole, becoming locked automatically to hold in position the shoe gages which will properly locate the shoe with respect to the sole when the shoe is placed thereon. Pressure is then applied to the shoe to press the sole and shoe against the pad, the pressure being provided by uid pressure operated mechanism which forces the sole and shoe down- 5 wardly some distance into the pad when the full pressure has been applied. It will be seen that if the gages remain in locked engagement with the sole and shoe as these members sink into the pad there may be danger of some of the gages soarring the upper of the shoe as it moves downwardly past the gages or danger of the gages indenting the shoe during the remainder of the pressure applying operation.

It is an object of the present invention to prevent any damage to the shoe by the sole and shoe positioning gages during the pressure applying operation.

With this end in view, afeature of the invention consists in the provision of improved means for releasing or unlocking the sole and shoe gages during the application of pressure to the sole and shoe and for withdrawing these gages from operative engagement with the sole and shoe. As herein illustrated, the gage releasing and withdrawing means is fluid-pressure-controlled and is connected with the same source of fluid pressure supply as the iiuid pressure operatedmechanism for applying pressure to the shoe. The releasing and withdrawing means is preferably arranged to operate after suilicient pressure has been applied to the sole and shoe by the building up of a predetermined pressurein the pressure system of the machine to clamp the soleand shoe on the pad and thereby to` insure against relative displace- 55: ment of the sole and shoe after the gages have been withdrawn but before the full pressure has been applied.

The gage releasing and withdrawing means, as herein illustrated, includes a iiuid-pressure-operated. plunger constructed and arranged through a pivoted member to actuate gage operating and controlling mechanism associated with each pad and thereby to release and positively withdraw or retract all the gages simultaneously to their out'er or inoperative positions. In order that this action may not occur until after a predetermined pressure has been applied to the sole and shoe, the plunger is arranged to operate against a spring the resistance of which may be varied as desired for operating, for example, on mens, womens or childrens shoes.

In accordance with another feature of the invention'means is provided for latching the gages on each pad box in their withdrawn or inoperative positions until the pressure applying operinsuring ation has been completed, thereby against the return of the gages into engagement with the sole and shoe before the latter have been removed from the pad. As illustrated, the latching means is adapted to operate automatically when the gages have been moved into their outermost or retracted positions Further means, operated by return of the pressure applying mechanism of the machine to inoperative position, is provided for releasing the latch just before the pad with which it is associated re-enters the operating station at the completion of the pressure applying operation. This latch releasing means is also arranged to maintain the latch in an inoperative position until the gages have positioned another sole and' shoe on the pad and the pressure applying mechanism has'been moved into operative position. At this time the latch is permitted to return to an operative position so thatV when a predetermined pressure has been applied to the sole and shoe on the pad, and the gages are released and withdrawn by the mechanism above referred to, the latch will act automatically to lock the gages in their withdrawn positions,

Although the latch is released automatically before the pad is fully. located in the operating station, so that the gages are then under the control of their actuating mechanism, the construction and arrangement is such that the usual gage retracting mechanism with which the machine is provided comes into play to prevent the gages from moving inwardly toward the sole and shoe even though the gages are not locked in their Withdrawn positions.

With the above and other objects and features in view, including novel details of construction and arrangement of parts, the invention will now be described in connection with the accompanying drawings and will thereafter be pointed out .in the claims.

The mechanism of the present invention for releasing and withdrawing the sole and shoe positioning gages is illustrated herein as embodied in a machine of the type disclosed in the Ballard et al. patent referred to above, the drawings and description being limited to those portions of the machine which are directly concerned with the invention. For a more complete description of the portions of the machine not illustrated or described herein, reference may be had to the patent mentioned.

The cement sole attaching or laying machine comprises a base or column I0 upon which is mounted for rotation about a vertical axis a turret I2 which carries a plurality of pad boxes I4 arranged to be presented in succession at an operating station located at the front of the machine. Each pad box I4 is provided with a yielding pad I6 adapted to receive a sole A and a shoe B (Figs. 2 and 3). The sole A is positioned on the pad by an operator and it is held in position thereon by sole and shoe positioning mechanism best illustrated in Figs. 3 and 4, this mechanism functioning also to locate the shoe relatively to the sole.

The sole and shoe positioning mechanism comprises gage arms I8 for operating on the sole and shoe in the vicinity of the ball line and gage arms 20 for engaging the sole and shoe approximately at the tip line, the gage arms 28 being arranged in crossed relation to each other, as shown in Fig. 3. The gage arms IB carry at their forward ends sole gages 22 and shoe gages 24, the latter being adjustable relatively to the sole gages by eccentric adjusting mechanisms provided with handles 25. The gage arms 20 for the tip line are likewise provided with sole gages 28 and shoe gages 3D which are relatively adjustable by means of handles 32. v'Ihe gage arms I8 are pivoted by horizontal pins 34 to carrier members 35 which, in turn, are pivoted on substantially vertical pins 38 carried in a frame member 4U secured to the pad box. The tip line gage arms 20 are pivoted on horizontal pins 42 mounted on separate carrier members 43 also pivoted on the vertical pins 38, and these gage arms and the ball line gage arms I8 are freely movable about their respective pivots so that the sole gages on the ends of the arms rest by gravity on the pad I8. Both pairs of gage arms I8 and 20 are normally urgedv in a direction to move the gages toward each other and toward a sole and shoe on the pad by

springs

44, 44 and 46, 48, the springs 44 acting upon the ball line gage arms I8 and the springs 46 acting upon the tip line gage arms 20.

As shown in Fig. 3, the

carrier members

36 and 43 are provided with relatively thin overlapping portions 4l in which are formed arcuate slots 48 struck from the centers 38 and through which extends a locking bolt 58. As fully described in the Ballard et al. patent, the locking bolt is arranged to be drawn downwardly into clamping relation with the overlapping portions of the

carrier members

36, 43 by mechanism not fully disclosed herein but including a lever 52 (Fig. 3) and a rocker member 54 to lock the gage arms in operative position after the sole gages have contacted with the edge face of the sole on the pad. In this way the position of the shoe relatively to the sole is determined by the locked shoe gages 24, 3U carried by the arms I8 and 20.

The gage arms I8 and 20 are moved about their vertical pivots to withdraw the gages carried thereby from engagement with the sole and shoe and to move them into their outer or inoperative positions by swinging movement of the rocker member 54 toward the left, as viewed in Fig. 3, this rocker member, as described in the patent referred to, carrying projections 56 each a1- ranged to engage a roll on a gage arm and to move the gages into their inoperative position simultaneously. Movement of the rocker member 54 in the direction indicated to withdraw the gages operates first, however, to release the locking bolt 50 and thereafter to move the gages into their withdrawn positions against the action of their operating springs.

The rocker member 54 is actuated by a substantially horizontal link 58 held in this position by a stationary guide member 5i) provided with a slot which engages a pin 82 mounted in the righthand end of the link, as viewed in Fig. 3. 'Ihe pin 62 carries a roll 64 which rides in a slot 66 formed in an upright arm 88 of a bell crank lever pivoted to the turret on a shaft 'i2 and having a lower, substantially horizontal arm 'lil (Figs. 1 and 6). Movement of the bell crank lever 88 in a counterclockwise direction, as Viewed in Figs. l and 6, actuates the rocker member 54 to release the locking bolt 50 and move the gage arms I8 and 2l] against their springs in a direction to withdraw the gages from the shoe and sole, and movement of the bell crank lever in the opposite or clockwise direction permits the gages to move inwardly toward a sole on the pad under the action of their

springs

44, 46. A spring 14, connected between the arm 68 and a pin 'I6 on the turret, tends normally to swing the bell crank lever in a clockwise direction into a position where the gages will be contacting with a sole on the pad, the movement of the bell crank lever being limited by a stop-screw 18 arranged to engage theturret I2'.

The mechanism with which the machineisprovided at-the operating station for actuating the bellcrank lever 68 and thereby operating the sole and shoe positioning gages comprises a stationary cam fastened to the upper end of astandard 82` and provided with an inclined surface 84 arranged to engage a roll 86 carried by a shouldered screw 8T extending through the horizontal arm 'ilof the bell crank lever 63, As each pad box moves into the operating station from left to right, as viewed in Fig. 1, the lever 581 associated with that pad` box4 is, in the machine of the pat entreferred to, swung in a counterclockwise di reotion bythe cam 80 to release the gage locking bolt and withdraw the gages to inoperative position through thel operation of the rocker member 54'., When the pad box comesto a stop at the operating station the roll 86 would ordinarily be resting on a ledge member 88 (Figs. l and 6) forming a continuation of the. stationary` cam 8G, this ledge member being carried. by, a lever 95 pivoted at 92 on the stationary cam 8U.

In the machine disclosedf in the patent mentioned, when it is desired to swing the bell crank lever 68 of the pad box at the operating station in clockwise direction (as viewed in Figs. 1 and 6) and thereby operate the rocker member 54 to permit the gages to be moved inwardly by their springs into contact with the edge face of the sole; the lever and the ledge member 88 carried thereby are moved downwardly by a trea-dle 94 (Fig. 1) connected` to the lever 9D at 95 by a treadle rod 96 working against a treadle elevating spring 98. As the parts are shown in Fig. 6, the ledge member 83 has been moved downwardly by depression oi the treadle 94 but, because of other mechanism which forms a part of the present invention, the bell crank lever 63 has not been swung in a clockwise direction by the spring 1d to bring the stop screw 'I8 against thel turret'and, accordingly, the sole and shoe positioning gages are still maintained in their withdrawn or retracted positions.

In the machine of the patent referred to, after the sole gages have been permitted to come into. engagement with a sole on the pad` in the manner described, it is necessary to retain the lever` Sil. and the ledge member 88 in a lowered position so that the gages will remain locked against the sole. For this` purpose a latch ii is provided, the latch being pivoted on a pin 02 mounted in the stationary cam 80 and being adapted to snap over a shoulder on the lever Si! under the action of a spring HM. connected to the lever 90 at |05 and tending constantly to urge the latch in a counterclockwise direction about its pivot |02. After the sole and shoe have been properly positioned on the pad Idand have been pressed against the pad by the pressure apply ing mechanism, the turret rotating mechanism of the machine is operated to cause the pad box and the gage actuating mechanism associated therewith to move out of the operating station.

Vifhen this occurs a roll H35 on the center 'i2 ridesalong an inclined cam surface ll on the lever 9B and engages an upward projection H35 on the latch |00. This disconnects the latch from the lever S01 and the latter is permitted to return gradually to its original elevated position by theinclination of the cam surface iii?. As stated above, the mechanism just described is provided` in the machine of the BallardY et al. patent and. isv fully disclosed therein.

The machine of the patent mentioned is also provided with hydraulically operated pressure applying mechanism` for pressing the shoe B against the sole A after they have been properly positioned relatively to each other on the pad by the gagemechanism, theshoe and sole, of course, having been previously treated with cement whereby the sole is to become attached either temporarily or permanently tothe shoe bottom. Before proceeding to describe the mechanism oi the present invention for automatically withdrawing .and latching the sole and shoe gages in inoperative position, a brief description of the hydraulic or fluid pressure operated mechanism for pressing the sole and shoe against the pad will be given.

Each pad box on the turret is provided with pressure applying mechanism comprising a cylinder HU (Fig. 2) having mounted therein a piston H2 carrying at its upper end a pivoted lever lili the opposite ends of which are disposed under levers H5 pivoted at H8 to a swinging frame member iZil, the latter being secured by a set screw 52E to a shaft 522 rotatably mounted in the turret. The swinging frame member I2@ is arranged for swinging movement from `a rearwardly inclined inoperative position into a substantially vertical operative position over the pad box by a handle ill. One of the two pivoted levers H6 carries a block i2 for engaging the top of a last in the shoe on the pad and the other lever it carries a toe rest 28 for engaging the toe portion of the shoe. Upward movement of the piston H2 due to the introduction of iiuid such as oil under pressure into the cylinder through a pipe iSil, causes the levers H to be swung in a direction to bring the abutments 26. i28 into engagement, respectively, with the last and shoe so that the sole and shoe will be forced downwardly against the pad, It will be seen from the foregoing that, if the sole .and shoe gages carried by the gage arms i8 and 2c re main in locked position against the sole and shoe as the latter are moved downwardly against the pad, some of the gages may Contact with the shoe in such a manner as to mar or otherwise injure the shoe upper. It is desirable, therefore, after the gages have operatet to position the sole and shoe relatively to each other on the pad, and the pressure applying mechanism has been actuated suihciently to clamp the sole and shoe against the pad so that they will be held there after in proper relative positions, that the locked gages should be released and withdrawn from en* gagement with the sole and shoe and maintained in their withdrawn positions for the remainder o the pressure applying operation, this action preferably taking place after a predetermined pressure of, for example, fifty pounds to the square inch has been built up in the huid pressure system of the machine so that suihcient pressure will have been .applied to the sole and shoe to these members against the pad and thereby prevent any relative displacement thereof. The mechanism for accomplishing this result, which forms the subject-matter of the present invention, will .now be described.

As indicated above, the bell crank lever 6B in the present construction, has not been swung in a clockwise direction, as viewed in Fig. until the stop 18 is against the turret l2, even though the ledge member 88 is illustrated as having been lowered by the depression of the treadle 34` and, consequently, the gages are not contacting with thesole and shoe. Thebell crank lever 68de held in the position shown in Fig. 6 by a latch 32 loosely pivoted on the upright arm 68 of the bell crank lever about midway of its length on a screw |34. In order that the latch |32 will always be free on the screw |34, it is actually pivoted on a cylindrical projection |36 (Fig. 5) formed on a clamping nut |38, the nut fastening the screw in the arm 68 but permitting the latch |32 to pivot freely about its cylindrical portion.

Secured by a screw |46 (Figs. 1 and 8) to the under side of the turret I2 is a stationary angle plate |42 having an inwardly projecting portion arranged to be engaged by a notch in the lower edge of the latch |32. IThe angle plate |42 may be adjusted lengthwise of the pad box about the screw |40 and maintained in adjusted position by a stop screw |44 (Figs. 6 and 8), the inner end of which engages a portion ofthe turret |2. The latch |32 is caused to hook over the plate |42 by swinging movement of the bell crank lever 68 in a counterclockwise direction after the sole and shoe have been properly positioned on the pad and a predetermined pressure has been applied thereto. The latch remains hooked over the plate to hold the bell crank lever in the position shown in Fig. 6 and thegages withdrawn during the rotation of the turret for the greater part of one revolution or just prior to the return of the pad box under consideration to the operating station at which time the latch is automatically released, in a manner to be hereinafter described, so that the gages will not be locked in their withdrawn position. The gages will not, however, be moved inwardly toward the sole and shoe by their springs at this time because the release of the latch |32 occurs at such a point in the cycle of the machine that the roll 86 on the horizontal arm 18A of the bell crank lever will have engaged the inclined surface 84 on the stationary cam 88 to retain the bell crank lever in substantially the same position it occupied when latched, although the latch is then raised up away from the plate |42 and is held in such position.

Before proceeding to describe the fluid pressure operated mechanism of the invention for swinging the bell crank lever 68 in a counterclockwise direction, as viewed in Fig. 6, to withdraw the gages and for permittingthe latch |32 to hook over the plate |42 to lock the gages in this withdrawn position, a description will be given of the mechanism for automatically releasing the latch |32 just before the pad box enters the operating station and for maintaining the latch in an inoperative position until the sole and shoe have been relatively positioned on the pad and a predetermined pressure has been applied thereto.

The swinging frame member |28 (Fig. 2) is swung forwardly into operative position over the pad by the operator, as stated, but is caused to return to a rearwardly inclined inoperative position automatically as the pad box with which it is associated is about to enter the operating station. The mechanism for effecting the automatic movement of the swinging frame |26 into its inoperative position, as disclosed in the Ballard et al. patent, comprises a segmental member |46 (Figs. 2 and 9) loosely mounted on the rotatable shaft |22 which forms the pivot for the swinging frame |20, the member |46 engaging a spring |48 projecting from a lug 15D on the lower portion of the swinging frame. Movement of the segmental member |46 in a clockwise direction against the spring |48 causes the swinging frame to swing rearwardly into its inoperative position, this position being determined by a stop block |52 on the cylinder which is engaged by a collar |54 fastened by a set screw |56 to a sliding rod |58 arranged to slide through the block |52 and pivotally connected at its forward end by a pin |60 to the swinging frame. The operative or vertical position of the swinging frame |26 is determined by a fiber collar |62 secured by lock nuts |64 on the inner end of the sliding rod |58. Since the swinging frame is fixed to the shaft |22 the latter, of course, turns in its bearings as the swinging frame moves into and out of operative position.

The segmental member |46 is caused to rotate in a clockwise direction by a roll |66 (Figs. l, 6 and 9) arranged to engage the inclined surface 84 of the stationary cam 86 as the pad box moves into the operating station, this roll being carried by a member |68 pivoted to the turret on a pin |10 and pivotally connected to the segmental member |46 by a pin |12. As the roll |66 rides up the inclined surface of the cam 8|) the member |68 is swung about its pivot |18 to elevate the pin |12 and to force the segmental member against the spring |48 mounted in the projection or lug |58, thereby automatically returning the swinging frame member to its rearwardly inclined inoperative position.

The opposite end of the shaft |22 has secured to it by a set screw |14 a forwardly extending arm |16 (Figs. 6 and 8) having adjustably secured thereto by slot and screw connections |18 an extension piece |88 the upper edge face of which is curved in a manner to engage a relatively long flat surface on the lower edge face of the latch 32 and to raise this latch upwardly about its pivot |34 away from engagement with the xed plate |42. As the swinging frame |28 is swung into its rearwardly inclined position by operation of the mechanism just described, the shaft |22 turns to elevate the arm |16, |88 and cause it to raise the end of the latch away from the plate |42, thereby releasing the bell crank lever 63 so that it can be swung about its pivot 12 in a clockwise direction, as viewed in Fig. 6, by the spring 14 to permit the sole and shoe position gages to move inwardly under their operating springs into engagement with the sole A on the pad. Since the swinging frame member i2@ is swung automatically into this inoperative position as the pad box associated therewith is entering the operating station, the latch will be maintained in an elevated position at that time by the member |80 and the roll 86 on the arm 16 will engage the cam surface 84 on the stationary cam and come to rest on the ledge member 88. Subsequent depression of the treadle 94 lowers the ledge member 88 and permits the arm 68 of the bell crank lever to swing to the right, as viewed in Figs. l and 6, thereby permitting the sole gages to move yieldingly into engagement with the sole on the pad and to become locked in such position. After the shoe has been positioned on the sole and a part of the sole attaching pressure has been applied, the bell crank lever 68 is caused to swing automatically in a counterclockwise direction, by mechanism next to be described, so that the latch |32 will hook over the fixed plate |42 and lock the gages in their open or withdrawn position, the member |86 having been lowered by turning of the shaft |22 when the swinging frame member was moved into its Vertical position by the operator to apply pressure to the sole and shoe and thus` permitting the elongated at surface on the latch 32 to ride on the upper edge face of the plate |42. Accordingly, further movement of the IBO :latch toward the left, as viewed in Fig. `6, by the mechanism vnow to be described, will Vcause the Alatch to hook over the plate |42 and lock the 'substantially *horizontal cylinder having a bore of .substantial diameter therein. Mounted for sliding movement in the bore in the cylinder |90 `is a plunger |92 having a slot |04 extending lengthwise thereof and through which a pin |96 passes, the pin serving to limit lengthwise sliding `movement of the plunger in the cylinder. A pipe |98 `is threaded into the lower side of the cylinder in an opening which communicates with the bore therein. 'I'he pipe |98 extends down- 'wardlyand is connected at its lower end (Fig. l)

tothe hydraulic pressure power system of the machine. This uid pressure system, as fully described in theBallard et al. patent, is provided with a seriesof valves throughthe operation of which Yin `a particular manner, by mechanism not 'disclosed herein, the free circulation of fluid such lasoil through the pressure system isstopped. For

the purpose of the present disclosure it is sufficient to state that this free circulation of oil through the pressure system is stopped by the depression Aof a treadle2200 (Fig. 1) which lowers a rod 202 having a collar 204 (Fig. 2) `thereon and between which and a washer'206 is a compression spring 208. The washer `206 rests on the `forked forward end of `a lever `2|0 pivoted at 2|2 and hav-- ing an inner arm 2|3 connected at its inner end `by a link `2|!! to an arm 2|5 forming apart of a pressure inducing valve 2 I8 which is provided on `the machine for controlling the uid pressure system. When thepressure .inducing valve 2|8 `is open the oil circulates freely through the system and when the valve is closed fluid pressure is built up in the system and Iin the pipe V|30 to elevatethe piston I2 andapply pressure to the soleland shoe, the `fluid passing through `a three-way valve mechanism 220 (Fig. l) .before entering the cylinder 'I t8. The amount of pressure which may be built up in the :system may be as high `as 300 -pounds per square inch'if such a pressure is necessary or desirable in attaching -a` sole to a Yshoe bottom. The valve 2|8 is normally held closed by a spring `222 anddepression of the treadle 200 `raises the arm2 6 to open -the valve and cause the fluid pressure mechanism Ito operate.

Returning now to the gage `withdrawing -mechanisnn illustrated in Fig. 9, the cylinder |90 `has `extending upwardly `therefrom a pair of arms 224 (Figs. 'and 9) in which 'is rotatably mounted `a vpin 226 havingsecured thereto by a set screw `228 a member l23|). The member 230 has a downwardly projecting lug 232 located opposite the forward end of the `plunger' |92 Aand a screw 234 is threadedlthrough the lug` so that its Yinner end contacts with the plunger. The screw 234 `is held against the plunger |92 by a tension spring 235 extending through an opening231 in the member 280 and connected theretoby a pint238,lthe spring `being connected `at its other end to the cylinder |90 by a hook 249 threadedinto an vupwardly progages in Athis position.

in the system and in the -cylinder |90 before -the plunger will start to move to `swing the member 230 upwardly about the center 226.

The `member 230 has an upwardly facing `projection 244 thereon having `a `somewhat convex top surface. The projection 244 is .arranged to underlie a circular end portion 246 of a -lever `248, best shown in Fig. '7, and secured to the horizontal arm of the bell crank lever-68 -by the shouldered screw 8T which carries .the lroll 88. The opposite or left-hand end of vthe lever248, as viewed in Figs/6 and 7, is bifurcated and straddles the shaft '|2 so that the lever will lswing about the shaft with thearm 10.

As indicated above, when the pressure built up in the cylinder `|90 overcomes the resistance `of `the spring 236, the piston |92 moves forwardly for tothe left, as viewed in Fig. 9, and, as thepressure in the cylinder increases, the plunger iforces `the member -230 upwardly about vthe pivot until the projection 244 engages the portion 249 -of `the lever 248 therebyswinging this ylever and the arm 10 of the bell crank lever '.68 (towhichit isvconnected) upwardly or in La counterclockwise `direction about the pivot `'|2. This action of thefbell crank lever operates 'the rocker member `54`to unlock and withdraw the fsole and shoe'positioning gages from engagement `with the sole :and shoe and to return them to their outermost or inoperative position illustrated in Fig. 4. The latch |32, whichhas been permitted by the lowering of the member |80 to ride on the plate |42, drops `into latched engagement with `the :plate when the gages are fully retracted, thereby `locking the In order that oil which may leak from the bore of the cylinder `|90 through the reciprocativemovement of theplunger |92 will not run over the outside of the machine or reduce the amount of oil in fthe .fiuid pressure system, the cylinder |90 is provided-with a drain pan or lip 252 which is arranged to catch any oil which leaks "from the cylinder. Apipe 254 is connected to the portion l252 to carry the `oil back into the uid pressure system of the machine.

Although the operation of the mechanism which forms the subject-matter of the present invention will be apparent from the foregoing description, a summary thereof will be here given tion, the gage mechanism being held in this posi l tion because `the roll v86 is resting on the ledge member 88 which, at this time, is in `its elevated position. The :gages are free, however, to move inwardly toward the sole .and shoe, through the operation of their respective springs, because the swinging frame member is located inits rearwardlyinclined inoperative position so that the .member orarm |80 is engaging the latch |32 and holding it above the fixed plate |42. Theopera- Vtor places a `sole on the pad and deprcsses the-- gage treadle94 to lower Vthe Vledge memberl88 and `permitthe

sole gages

22, 28 yieldingly to find the `edge face of the sole, after which the :gages automatically lock. rThe operator then places the shoe between the locked `shoe gages, which position it relatively to the sole, and 'he `swings the swinging frame member `|20 forwardly by the handle i |24 into its substantially vertical operative position, as shown in Fig. 2, this action turning the shaft |22 `and swinging the `member |80,

downwardly away from the latch |32, thus permitting the latch to descend so that its straight edge portion at the left of the notch in the latch, as viewed in Fig. 6, rides on the upper edge of the plate E42 but the latch does not hook over the plate because the bell crank lever 68 has been swung too far in a clockwise direction, as viewed in that figure, to permit the notch in the latch to engage the plate.

The operator then depresses the pressure applying treadle 26E] which operates the valve ZIS and sends fluid under pressure into the cylinder IIIJ to elevate the piston H2 and to apply hydraulic pressure to the sole and shoe. As the pressure on the sole and shoe increases the uid under pressure which is simultaneously entering the cylinder |90 through the pipe |98 is building up the same pressure in the cylinder. Accordingly, if the spring 235 is set to withstand a pressure of fifty pounds per square inch in the system, when this predetermined pressure acting on the piston H2 has been applied to the sole and shoe the spring will yield. As the plunger moves forwardly under the increasing pressure in the cylinder |99, the member 239 will be swung upwardly to elevate the lever 248 and arm li) and thus rotate the bell crank lever 68 in a counterclockwise direction about its pivot l2 until the notch on the latch |32 drops over the stationary plate |42, this movement, of course, operating the rocker member 54 to unlock the sole and shoe gage arms and, through the lugs on said rocker member, to force these arms into their outer or retracted positions against their operating springs. Thus it will be seen that the sole and shoe gages are released, withdrawn and latched in inoperative positions automatically by fluid pressure operated mechanism when a predetermined pressure has been applied to the sole and shoe.

The gages remain latched in their inoperative position as the pressure on the sole and shoe increases to the desired amount, so that there is no danger of the gages scarring the shoe as it sinks into the pad. The operator then actuates the turret rotating mechanism and the pad box moves out of the operating station and intermittently around the machine as the other pad boxes are loaded in the manner described, the gages remaining latched in inoperative position all the while. As the pad box under consideration approaches the operating station, the roll |66 rides up on the stationary cam B and automatically swings the swinging frame member |23 to its rearwardly inclined position through the operation of the segmental member |45, the pressure on the sole and shoe having, of course, been relieved by other mechanism on the machine before the swinging frame member is swung rearwardly. Rearward movement of the swinging frame |29 turns the shaft |22 and actuates the member |80 to elevate the latch |32 and hold it out of engagement with the plate |42. At the same time the roll 85 has moved far enough along the inclined surface 84. of the stationary cam 8S to prevent the released gages from returning under the action of their springs into engagement with the sole and shoe. Accordingly, although the gages are not locked at this time and are free to be moved into operative position by their springs, if permitted, they are nevertheless retained in their outer or retracted positions by reason oi the engagement of the roll 86 with the cam 8l! and the ledge 88. After the shoe, with its sole attached thereto, has been removed from the pad the operator places another sole on the pad and repeats the operations described above.
