In attaching a sole to a shoe in machines of the character disclosed in the applications iden tified above a pad box is used to apply pressure to the sole. The pad box consists of an opentopped metal box with a verticallymovable bote; tom, containing a hollow flexible closed bladder or pad the upper surface of which is more or less. formed to suit the shape of the shoe bottom,
the lower surface of which can be pressed upward when the bottom of the metal box is displaced. The pad is filled with "water. Thepad box is provided with pressure receiving members generally in the form of a pair .of arched connected to the metal box and carrying plungerswhich can be pressed down over the .ends of a shoe and sole resting on the pad to force the shoe and sole into proper contact with each other and the pad witha socalled preliminary pressure.

In the prior constructions of Ballard and'Finn the gagesfor the toe end of the shoe were provided'in two pairs,,jone pair contacting with the sole and shoe at the narrowing sides of the toe and'the other pair contacting with the sole and shoe at the ball.

'The illustratedmachine is of this emirates.
An object of the presentirivention is to improve the machine in order toenable it to'handlechildrensshoestobetter advantage; It has thepad box plungers in the been "found that such shoes can be advantage-- 7 ously treated by-locating the ballportiOri of thejshoeand sole at the. same place'on the pad, irrespective of the size of the shoe, and; this makes it advisable,toprovide'for the adjustment of 1311812631 pressure bail andff oramoresuby'stantial range of longitudinal" adjustment for thefront pressure bailof the padbox to insure that the'plungers shall contact with the shoe and'its last in the most advantageous locations.
I have therefore provided the pressure'bailswith an adjusting means which, as illustrated, moves them both simultaneously toward or from that locality of the pad ,box occupied by the ball portion of the sole, preferably with a fixed velocity ratio so that'they will exert pressurefiin -thesame way on shoes of all lengths;
Another feature of the invention resides in the toe gaging mechanism for the 'sole'and shoe." I, have found that only one pairof gages for the sides-of the foreparts o'Ithesole and shoe are necessary in the c'ase'of small shoes; engaging the shoe and sole at about the tip line. In
accordance with the inventionl have provided 7 in the prior Ballard and Finnconstructions. I have a toe end gajgewhich was not present also provided means for locking the gage carrying carriage against movement toward the shoe operated by contact of this toeend gage with thefsole, and in accordance with another inrportant ieatureof the invention I have provided 'means'for locking the toe end gage against any backward movement under the pressure oi the -with the treadlemovement' whichproduces 'it.
In the illustrated machine awedge is provided which is drawn automatically, into. the connection between the treadle and the pressure applying levers to shortenthis connection, and which so operates until the accumulated pressure has generated suiiicient friction to prevent further sliding, when the mechanicaladvantage' of the system becomes fixed...

The pad box, as an independent and removable part of the complete apparatus, will first be described. See Figs; 12 to 16. V k
- As shown, it comprises a metal casing or box 10 open at the top and with a bottom 12 hinged at 14. This bottom is raised asshown in Fig.
14, by a cam 16, engaging a roll 17 on the bottom -12, and pivoted at 18. The cam 16 is operated by a push arm or handle 20, as will be described, 1 r v This box 10 is occupied by a pad'22 whichis made of flexible and somewhat elastic material as rubber with,fif desired, a layer of fabricvulcanized into it to avoid undue stretching. This pad is filled-preferably withwater in quantity sufficient to fill, it withoutdistorting the shape into which it has been molded (so that its upper surface will correspond roughly to the shape of a shoebottom). The pad 22 is not fastened in the box. 10, but has a limited up-and-down movement in it, as explained in the application of S. J. Finn, Serial No. 557,496, filed August 17, 1931, which shows a pad box similar to the, one
1 disclosed herein.
Obviously, the pad box.
The water-filled pad has a plate 24 on its toe end which forms a part of the closure clamp of the pad, and which has hooks 26 at its top. This plate 24 can slide. up and down in the box 10 by virtue of holes in the front .wall of the box which accommodate the projecting elements of the closure means,.as described in the last-mentioned Finn application.
The pad 22 may be conveniently surmounted by a so-called blanket 28, between which and the pad 22 is a metal plate 30 which is hinged under the hooks 26 by means of a pin 32 mounted in the plate 30. The plate 30 carriesa flexfiible flap of -leather 34 which extends back of the rear edge of the plate, as described in the Firm application.
The blanket 28 will preferably be made of soft rubber and have vulcanized into its ends mask plates 36, 38 of thin flexible metal, as described in the Finn application, and for the purposeexplained therein. i
Means is provided, as in the Finn construction Y mentioned, for holding the front end of the pad.
and the superimposed for'epart portion of the blanket normally raisedtoan extent suiiicient tocorrespond to the longitudinal)curvature of the bottom of a last forepart. Thismeans, as iliustrated, comprises springs 40 (Fig. 12) mounted ,on the box 10, with their ends under the pin 32, which is vertically movable in slots 42in the box 10. the pad and blanket raised and the preliminary pressure, when applied, brings the shoe into proper contact with the blanket, and adjusts the vertical position of the blanket and pad. When the operative pressure is applied to raise the bottom 12 the hydrostatic pressure in the pad forces the front end wall of the pad outward,
as well as the top wall upward, and the friction engendered betweenjthe plate 24 andbox' 10 holds the front end of the pad in the position in which the application of the preliminary pressure has placed it. This structure and op.- eration are allfully described in the Finn application.
As also fully described in the Finn application,
hooks 42' are molded into the blanket'in proper position to engage studs 44 on the box 10 to placethe blanket in properposition and limit its. upward movement. Therear end of the blanket is confined by latch plates 46. The :front end of the blanket is held against hori- The springs 40 normally hold 'zontal displacement by upstanding parts 48 of r the side walls of the box 10. V
The box 10 is provided on its ends with lugs such. as 50 ,to engage with gage lugs on the pressing ma'chine',as explained in the Ballard application cited.
' The novel pressure mechanism associated with on each side, are mounted to slide horizontally the box 10 will now be described. Rods 70, one
in lugs '72, 73 on the sides of the box. The legs of the U-shaped front pressure bail 74 are pinned to theserods sothat the sliding of the rods will move the bail fore and aft. The rear ends of the bars 76 are formed as racks 76, engaging below pinion devices 77 mounted in the rearlugs 73, which pinions engage on their upper sides short racks 78 sliding in grooves in the box 10. The legs of the rear pressurebail 8d are pivoted on these racks 78 at 82.
The central parts of the bails 74, 80 are similar to those shown in'the Ballard application.
Each has a plunger 84 with a pad on the front, and an abutment on the rear bail to engage the I azar-m a around axes puneys' 5142, 444 (Fig. n and' leads toe of a. shoe and the cone of itslast, respectively, the plungers being spring-pressed' upward movement of the bails '74, 80 in adjustment; It, is contemplated, however, that an integraldou ble pinion may be used, the two parts having different diameters, 'in case other than a 1: 1 movementof the bails is desired I have found inthe case of small shoes thatequal movements of the bails toward and irom each other are adequate to produce-satisfactory work. A pressing machine embodying certain features of the invention will now be described. Except as otherwise described herein, it is similar to that shown in the Ballard application cited. It consists essentially of a heavy frame 100 having a flat work. table 102 forthereception 01 such a pad box as has been described above, and the table isprovided with gagingmeans, such as that described by Ballard for locating the pad box in a definite position on the table.
The machine carries to the left of the table a toe gaging mechanism: and to the rightof the table a heel gaging mechanism, the latter of which is identical with that" shown in the first Finn application mentioned. These gaging v mechanisms will now be described,
The toe gaging mechanism is carried by a bed 400 pivotally mounted at:401 on a bracket 402 on the main frame, the axis of the pivot '401' being'horizontal. The bed. 400 is in the form of an open bottomed trough with guideways 406 (Fig. 5) formed in its side walls. It is held in adjusted position relatively to itspivot'401 by an'expansible link 408 made in the form of a turnbuckle, and pivoted, tothe frame 100,
A gage. carriage 410 is arranged to. slide back and forth on the bed 400, by Jmean-s' of two pairs of rollers. 412, 414. The inner ends of the guide- I ways 406 are lower than the outer ends, and the front end of the carriage 410 drops a little as the rollers 414 fall down overa hill 416 connecting the outer and inner portions of the guideway.
The'carriage 410 has mounted on ita spaced cover plate 418 fastened above it by four screws 420, 422. SeeFigs. 3 and 4. Two gage bars 424' are pivotally mounted on the screws 420, and rest on the bed of the carriage 410 They each have an upstanding pin 426 on their outerends. Each of these pins engages in oneof a pair of converging slots 428 in the inner end of a gage operating member or banjo 430 which is slidij ably mounted above the gage bars and rests on a distance piece ,432. The distance piece slides over a longitudinal slot inthe bed of the carriage, through which slot a pin 434*, which connects the banjo to the distance piece, projects. terminating. ina slotted block 436,'(Figs. '7 and 8.), the slot 438: in which embraces the shaft 437 on the wheels 412 are mounted. The block 436 has'guide wheels 439 running against the bottom of the carriage 410,-. This slotted block 436 is. t0 acable 440 Which-passes as shown, comprise only m- 6 fthis lever mg wedge having a P nd-sl'ot connectm' toan arm 446011 a shaft. 448 in the'irame; 1.00.
When the arm 446, is depressed, the cable 440 holds the carriage'in'its outward positionxbya pull through the slotted block 436,-pin 434-, banjo 430, pins 426.,bars'424 and screws 420. A spring 450 connects the outer end oi the-banjo to the cover plate 418 through: a pin 452' mounted on' the plate; A cable 454 runs over apulley 456 mounted at"401 and is attached to the shaft .437. The other end of the cable 454 carries a weight .458. The weight 458 pu1ls theshait: 437
normally to the inner end of the slot 438, pulling the" carriage 410 inward; so that the weight 458 and the arm446 thus pull against each others! The spring 450 is at this-time stretched-and at a later time moves the banjo inwardly on the carriage by sliding of the block 436; over the shaft 43'I 'when the pull of the cable 440 is slackened, to set the gage bars 424,
'as will be seen. i The inner end of the banjo carries an upstanding pin 460 which runs-in a guide slot 462 in; the cover plate 418-, guiding this end of the'banjo when such sliding movementtakesplace. I A toe, gage bar'464-is mounted to slide in wardly and outwardly on thecover plate. 418. It' has a'guicle' slot'i466 embracing the pin'452 and is guided at its outer end by astrap 468 on the cover plate. Its rear end contacts with a lever 470'pivoted at 4'72 onthe cover, plate, and the other end offthe lever 4'70 has a notch 4'74 (Fig; 4) nonnally'engaging, a little block on the. under side of a lever 476 pivoted at 478 on a lug attached tothe cover vplate 418., The under side of the lever 476 carries at its outer end a tooth arranged toeng'age in' a rack 480 mounted on the bed 400 when the lever 476 is swung clockwise by a spring 482pwhich connects it to the lever4'70. This action is normally prevented by theengagement of the notch 474- with the little block on the-lever fl'lfi. -When the gage bar 464 is pushed outwardly, it turns the lever 470- clockwise, releasingthe notch from the block, thus permitting the lever '476 to swing into position to engage-the rack 480. Such engagement prevents subsequent inward movement of the carriage 410 onthe bed 400. The action just described is due, as willfbe seen in more detail, later, to the engagement-of a gage on the end of thelbar 464 with the toe of a sole, as the carriage 410 slides along the bed 400 toward the sole, such engagement sliding'the gage bar 464 backward on "the cover plate, and causing the carriage to be locked on the bed shortly after the gage has struck the toe of the sole, The latchf4'74, 4'76 is reset when the carriage 4-10 is pulled outward, by engagement of the tooth on the lever 476 with a cam:483. See-Fig. 3.
In some instances the operator has to settle the. shoe into proper position bypressingfdt firmly against the toe 'gage, and therefore} in accordance with aifeature of the invention,

The wedge catches it right where it is, so that there is no lost ,motion" or displacement ofthe' gage bar.
, The gage bar 464 has a slidably adjustable block 493 (Figs. 5 and 6) on its inner end with a block 494 pivoted to it at 49 6, and a stop screw 498 in the. block rests against a ledge 500 on the bar 464 to prevent undue downward movement of the block .494. The block 494 carries a sole gage member502 above which is mounted a sliding toe gage 504 adjustably projected over the sole gage by an eccentric 506 operated by ahandle508.- The side gage bars 424 carry on their ends These are similar to those desoribedin the Ballard application mentioned. and consist of a sole edge gage adjustably overhung by a shoe gage, as there described.
' .As stated, the heel gaging mechanism is at the same as that shown and described in-the first Finn and the Ballard applicationsmentioned above. Itis arranged generally like the toegaging mechanism on a. pivotally adjustableslideway 520. It may be briefly noted that its carriage 522' carries 'a heel end gage'bar 524 and a pair of lever arms 526' carrying shoe positioning gages at. their inner ends and also another pair of sole positioning gage carrying levers lying directly below the levers 526, the
' arrangement-being such that when the heel end gage bar 524 is brought to rest by striking the end of the sole or the operators thumb (in case l efinds this advisable to prevent the gages from moving .too far forward-on thesole), the carriage 522 will be brought to rest and locked against further movement on the slideway 526 in a similar manner. to that explained in corn kept tensien.
nection with the toe gaging mechanism above.
The gage carrying carriage 522'isp'ulled inwvard by a cable 523 and attached weight 530 and is held in outward position by a cable 532 attached to an arm similar to the arm 446 on the shaft 448 This arm is normally latched down by a little treadle 534 located a little above a treadle 536, which is in effect the end of the arm on the shaft 448. ,Whenthe latch is released the t 446 can turn under the pull of the weights 458, 530, allowing the toe and heel gaging mechanismsto slide toward the shoe;
Up 'to the-timethe carriages 522 and 416 are brought-[to rest they are eased slowly in ward under the control of the operator through the treadle 536, the cables 532 and 440 being 7 The-cable 532 is connected to a block 538 which slides in the carriage 522 lilcethe block 436.1'The block 538 is connected to the gage carrying lever arms and when pulled to its outermost positionon the carriage V 522 is looked, as stated, the cable 532 is released as the operators foot continues to rise a,

When the carriage thus ' will be briefly mentioned here.
The operative pressure is impressed on the shoe by the action of a dropping Weight 556 which, as fully describedin the Ballard application, operates to raise thepivotedfloor l2 0:": the pad box, thus applying a pressure of 60 or 76 pounds per square inch to the shoe. This weight is lowered under power control and raised by power and at about the time it reaches its'lowermost point the cam 16 is automatically actuated by a member 552 (Fig. 2) which contacts with the operating handle 20 of the cam 16, as fully explained in the Ballard application.
The weight operating mechanism is controlled by a one revolution clutch and is tripped by a lever 554 (Fig. 2) located'in the front part or" the table 10 2. 1 y
The mechanism for impressing the preliminary pressure on the shoe will next be described. See Figs.'9, 10 and .11. A standard 665) is mounted on the :frame of .the'machine and has inde-,
pendently pivoted to it on a shaft 662two levers 664,606 which overhang the pad box. A ,bar
608 having aflat face 610 is loosely mounted at its ends. in these levers, which are depressed over the pad box by pushing down on the bar 668. This push is by a treadle 612, which is held up in inoperativeposition by a spring 614 and is connected by a rod 616 to a (.;-shaped lever 618 pivoted on the, shaft 602, with the 8 formation embracing the rod 668. The upper part of the C has transversely slidably mounted in it a block 620' the position" of which is.v controlled by a rocking lever 622 mounted on a vertical shaft 624 mounted in a lug626 on the upper arm' of the C. The lever 622 is spring held down against the lug 626 so as to engender substantial friction when it moves. Two stop screws 628, 630 limit the movement of the lever .by striking the upper armjoi": the C. The end pin-and-slot connection of the lever 622 has a with the block 620,.
.The slide block 620 is provided with a trans- I verse sliding block 632, whose ribs 634 run in.
guides in the block 620. This block 632 is shaped, and its lowersurface rests on the. fiat face, 610. 1It-is through thisbloclr that the ,6-
' shaped lever 618 transmits pressure to the bar 610 and levers, 604, 606. The rear end of this wedge block 632 is provided with a' vertical slot 636 which Works on a pin 638 mounted-in the 1 c -shaped end of a lever 640 pivoted at 642 at the upper'end of an extension of the upper part The wedge block 632 rear end sliding on the pin 638.,
A link1'644 is pivotally connected at 646 and 648 to the lever, 640. and the upper end of. the standard 600. .The pivotal connection at 648 is a sliding one, there being a spring 650 to pull the pivot 646 toward the standard, so that. normally .the sleeve 652, resting. onlock nuts 654, rests also againstv the pivot 648. V U Suppose now that the treadle .612 isdepressed V "1,92 .172 to pull down the rod 616 and thelever 618..
As" the lever 618 descends toward the plungers of the pad box, carrying with it the blocks 620, 632, the spring 650 tends to hold the lever 640 against movementas the, pivot, 642 swings 'forwardand down around the center. 602. The
- vresult is that the lever 640 swings counterclock wise around the pivot 646, which at first remains "nearly motionless.
box plungers down to effective contact with the shoe, thus forcing the shoe into the pad, the
resistance to their .movement increases, thus 1 increasing the friction between the wedge 632 and block 620 and bar 608. When this friction becomes great enough the wedge ceases. to slide between the block 620 "and bar 608 and the spring 650 begins to yield, allowing the link 6441 to. slide through the pivot pm 648, as the downward motion-of the C-shaped lever continues,
until adequate preliminary pressure hasfbe'en put on the shoe. Q Thus, Ior the same treadle action, a considerably greater initial movement of .the'levers.
604, 606 at. low mechanical advantage is produed than in the Ballard and Finn constructions mentioned, so that when a small shoe is treated, requiring the pad box plungers to descend to a greater degree than in the case of a large shoe, the pad box plungers may be adequately depressed without danger of the treadle 612 striking the floor. In case it should do so, however, a release of the treadle will permit the parts to recover their initial positions (except that the pad box plungers are held down by their ,ratchets, in the positions to which they have already been forced), and on a subsequent depression of the treadle the wedge 632 will slide farther in than it did on the first depression of the't'readle since the levers 604', 606 do not now strike thepad box plu'ngers at all j until later. in the operation of depressing the treadle. A wider part of the wedge'will therefore be used on the-second depression of" the treadle, and less treadle movement than before will produce the same pressure as before.
The bottom of the wedge 632 'isrounded to enable it to bear on the bar 608 in any vertical orientation of the bar and the adjustment of the block 620 enables the pressure transmitted by the C-shaped lever to be distributed as desired between the levers 604, 606 as explained inthe Ballard application mentioned; I I
The wedge 632 constitutes in effect a measur ing apparatus whichenables the'levers 604, 606 to be brought to positions where a substantial part of the preliminary pressure begins to be exerted by a comparatively small treadle movement, leaving a considerable range of treadle movement available for the application; of the major part of the preliminary pressure. 'In another pointof view. it constitutes 'ashortening device for the rod 616, which connects the op erating member 612 with the levers 604,606.
' In using the apparatus the operator puts the pad box in proper position on the machine table by means of the gages and places a cemented sole 700 on the top surface of the pad "or blanket, in what he judges-to be the' correct position. He then steps on the latch treadle 534' and holds his foot-on the treadle 536, raising the foot slowly. The weights 458 and 530 then ,carriage' to its slideway at banjo has released the*lever,484,' 486 which 'rately on the sole.

ward. This moves the toe gage bars 424 toward each other and toward the toe end of the sole. As they come together they will grip the toe end of the sole between them, the overhanging shoe gage; resting on the upper surface of the sole.- Meanwhilethe forward movement of the draws the wedge 438 behind the pin 492, thus. locking the toe end gage bar 464 against any 7 further backward movement. i fl- I imuitaneously with the above-described'om oration, the rear end gaging mechanism has moved" toward the shoe.' The end gage on the bar 52 4 strikes the end of the sole (or the operators finger, if he finds it to be. necessary to-stopythe gage carriage before this time in order to locate the gages properly), and the gage carriage is locked to its slideway as above described. .As' the cable 532 then "slackens the side sole gages are drawn forward and together and into contact with the sole. v
, The operator thenqplaces the shoe 702 on the sole pressing, its toe end between the toegages m and firmly'against the toe end gage 504. He
their trips the lever 540 and permits the rear shoe gages to swing into contact with the shoe; thus locating the rear end of the shoe .ac'cu- 1 130 The operator willthen swing the rear pros surebail 80,,which'ha's thus far beenswung to hisfright, outof the way, up over thes'hoe, and will, ifnecessary, by means of thelever'88, a'djust ,the' distance between the bails '74 and: to-fit the shoe. 1 I i He thenapplies the preliminary pressure'by stepping on" the treadle 612. The "C-shaped lever the levers 604, 606' which begin to descend over the pad box plungers 84. Meanwhile the wedge 632 is retracted'thus in efiectshortening the treadle rod 616 until the pressure on the wedge ment by its'own friction. The operator con;- tinues to depress the treadle 612 until sufilcient pressure'has' been imparted to the plungers to holdthe shoe and sole steady on the pad box,- and releases the treadle. The .ratchets 86. hold the pad .boxplungers in their pressing position.
The operator then trips the power mechanism throughthe member 554' which releases the weight;550,- pushing up the bottom of the pad 1 box and putting the shoe, under operativepressure, The padbox bottom is cammedagainst 13 5 retraction from its operative position by the] member 552, and'the weight isthen raised to its initial position. The pad box and shoe are then removed. from lthe" machine and set aside: for the cement toflset. I i
