This invention relates to machines for use in the manufacture of shoes, and more particularly, in various important aspects, to machines for shaping shoe uppers over lasts or other forms. The invention is herein illustrated in its application to means for lasting the heel ends of shoes in a lasting machine of the bed type, but it is to be understood that it is not limited to machines of that particular type nor to 1 cans for operating on that particular portion of the shoe.

In shaping the heel-end portion of upper materials (hereinafter frequently referred to inclusively the upper) over a last or other form, it is usually necessary to apply heavy pressure around the end of the upper in order to shape it closely to the contour of the end and side faces of the form and also to hold it e'tfectively in the required shape, especially near the edge of the bottom face of the forn during the shaping or wiping of its marginal portion inwardly over the form. Such pressure is especiallv necessary in operating on the heel end or the upper because of the presence in most work of a comparatively stiff counter, whether the counter has or l not been previously molded to approximate the shape of the form. For applying the pressure there is commonly used a heel band shaped to embrace the heel end of the upper and molded to conform approximatelv to the contour of the form, although somewhat flexible to permit it to be closed and opened and also to operate on uppers and forms of ditlerentsizes, together with mechanism for closing the heel band about the upper end form and for pressing it against the upper.

is an object of the present invention to provide improved for sha ing shoe uppers, and more particularly, in one important aspect, to provide etter means than hereapplyin shaping and holding the heel end portion of upper For the purpose in view the manown comprises in its organizaneans whereby fluid pressure is for the uppershaping operation. invention is illustrated in its application type of machine including wipers for 1930. Serial at. 433,422.

Wiping the margin of the heel end of the upper over an insole on a last, a heel band for embracing the heel end of the upper below the wipers, and a shoe support movable to carry the last and its shoe materials toward the heel band and wipers; and in combination with these parts there is provided a flexible fluid container shaped to embrace the heel band and eXpansible by fluid pressure to press the heel hand against the upper. The heel band is preferably made, as heretofore, of comparatively stiff, although somewhat flexible, material, such as sole leather, molded to approximate the contour of the heel end of the last, and as herein illustrated also the fluid container, which may be made of rubber, is molded to present toward the heel band a pressing face having a normal contour heightwise of the last approximating that of the heel band and the last, so that in its expansion no substantial stretching of any portion of it will be necessary to conform it preliminarily to the contour of the heel band before it becomes eflective to press the heel band against the upper. By the use of such pressing means insurance is aflorded that the pressure will be effectively distributed over the different portions of the upper around the heel end of the last and that the pressure will be adequate in the differentlocations to conform the upper properly to the contour of the last. While the illustrated embodiment of the invention thus includes a heel band and a separate fluid container for pressing it against the upper, it is to beunderstood that the invention is not necessarily limited to this particular combination. 7

In order to render the flexible fluid container efl'ective to apply the required amount of pressure to the upper andalso to prevent any damage to the contain r in its expansion, it is necessary to confine it effectively against excessive expansion in all locations except where its pressure is dir cted toward the upper. Accordingly theinvention fur- J- the r provides novel means for confining the container, the construction shown comprising automatically operative means for properly confining it under all conditions of use regardless of the size of the upper and of a the form over which the upper is shaped. Asf

' illustrated, the container is mounted in a receptacle which confines portions of it that are comparatively remote from the last, the

receptacle having upper and lower walls which extend inwardly toward the lastbut terminate at a distance from the heel band and-last to afford room for the opening and one of these walls andthe'heel hand, there are provided a plurality .of 1 members arclosingv of the'heel band. and to allow also for the operation of them'achine on uppers and lasts of diiferent'sizes. To confine porj 'tions of the container near the last against.

excessive expansion in "the space between ranged to'extend, inwardly beyond this wall and movable toward and from, thelast' to rmaintain effective control of the'container in all positions of the heel hand. These members, as illustrated,arearranged to opcrate in substantially contiguous relation to the wiping facesof the heel Wipers, and serve the'further important purpose of preventing contact ofthe flexible [container with the wipers and any substantial pressure of the conta ner on'the wipers. The constructlonis furtherfsu'ch' that the movable, controlling members are forced, inwardly toward. the

7 last by the expansion of, the container, and

thus fservefto transmit the pressure 4 of the "container to portions of'the heel band; and up perthat are located close'to the-wipers,where it is especiallyimportant that effective pressure be applied, while also cjonfining the container and preventing its contact with the wipers as above described; For preventing excessive'expansioniof theicontainer 1n the space between the heel band and the lower wall of the receptacle, and also-for prevent- .ingi excessive expansion lengthwise 'o-f the last, of the end portions of the containerflo= ca ted near the heel band 'at'theiopposite sides of the last, there is provided a flexible memher which extends around the heel band in overlapping relation to these different portions of the container andas illustrated ex "tends into a position between the container and the. heel band, together with -;members movablymounted in the above-mentioned receptacle for controlling the flexible member while permittingit to beflforced inwardly toward the lastfby the expansion of the container. Inthe 'differentjmeans thus provid 'ed for confining-thecontainer, for preventing it from engaging or pressing obiectionably on the wlpers, and'for transmitting 1ts pressure toportions of the upper, various novel features of the invention are to: be recog- "nized. is The. invention further provides novel means for applying toxone or more portions 7 of the upper greater pressure than to other portions. As illustrated; the construction is :such as to apply this greater pressure to'the dipper near the front end of its heel'por'tion in'locations near the edge-of the bottom face of the last, where especiallyheavy pressure is needed in order to spring the endsof the a counter; inwardly over portions of' the last that curve inwardly toward the shank To apply such pressure,jsome of the series of members above referred to as movable to transmit the pressure of the flexible'container to the heel band are formed astoipre? sentto the container D lfGSSUI-FQC31VHlg SLUT- faces of greater arealn' relatlorr to theirpressure-applying surfaces than is the case withother members;of theiJ-teries, In accordance withfurther feature alsothere is V provision for applying an especially effective pressure in ajlocation along the back seam offthe uppeijso as to conform this po-rtionfof the upper. closely to the contour of the last and to remove irregularities in the surface of the upper resulting fromthe'back ur ose ressure-a 1 in fin 'er extendp I V b D ing between the flexible container and the heel band and carried by :oneof the above mentioned-series of. pressing members, the arrangement being such that the finger is pressed inwardly toward-the upper both'by direct contact of the container" therewith and the pressureof the container on the movable member' whichsupports. it. In addition tothe greater pressure thus-applied, the fin controlled by a manually movable member which carried by a handlever utilized by the operator 'to[ operate the heel-lasting wipers, the construction-being such that by the same hand the operator may control the wipers and also admit pressure fluid to'the expansible icon'tainer or release it therefrom at will. As illustrated also the construction is suchthat the'valve mechanism is normally maintained in position'to release the fluid from the' container, so that suc'hrelease occurs seamstitchesthe machine including for this if the operator lets goof the controlling member, a device, however, being provided for securing the controlling member in positionto admit-thelfluid if desired. The ma chine herein shown'is constructed tojutilize compressed air as the pressure fluid, although it is tobe unders tood that the invention is not limited to the use of fluid of that character.

For

forcing the heel band firmly against the shoe all around the heel end portioniof the shoe to conform the upper materials, in cludingthef comparatively stiff counter a,'tothe contour ofthe last, there is providedqby this inven Etion a fluid-pressure device comprising, as illustrated, a rubber fluid container 84 adapted to-receive fluid underpressure and to be ex-v panded thereby. The container 84; is mounting 32 and 'is supported by a cover plate 86 secured on the lower face of the casting, the

casting and its coverplate thus serving as Y substantially in U-shapeto'embrace the heel band 34, and it is also molded to presenttoward the heel band a pressing face 87 (Fig.

' theshoe generaly similar to the molded contour of the heel band. Acoordingly, by reason of this 7 construction no substantial stretching or expansion of any portion ofthe The" construction thus far :briefly outlined is substantially like what has been used hereed within a recess provided for it in thecast- M 10) having a normal contour heightwise of narily to the contour of the heel bjand,jbut on the contrary the fluid pressureis imme .diately effective upon substantially all'por tions of the heel band that are operated upon by thepressingface87. This contributes efiectivelyto uniformity of pressure over' the corresponding portionsof the upper. v

In conforming the heel-end portion of upper materials to the contour ofthe last it is necessary thatefi'ective pressure be applied around the end and along the sides of the heel portion of the last in a location near the edge of the, shoebottom and accordingly 7 near the plane of the wiping faces of the wipers 36, in order to spring the counter into place" in that. locationand'to hold the upper j materialsclose tothe edge of the last bottom as the shoe support'rcceives its moVeduring thelasting of the margin of the upper overthe insole. f To apply such pressure, and at the same time to avoid objectionable interference between-the fiexiblecontainer 84 and the wipers, the construction shown is such that the portion of the heel band which is near the wipers is not engaged directly by the container but by movable members which transmit the/pressure of'the container to the heel band, these members having the further importantfunction of confiningagainst ex: cess vefexpanslon he'ightwise of the'last portionsof the container near the heel band,

, Tliesemembers comprise a plurality DIE slides V 88varranged in arseries around the heel band vand supported on a holder 90 which is mount edwithin'that portion of the casting32 that serves as a receptacle for the container 84; and hasahorizontal curvature similar to thatof I the container, thelatter being molded to. pro-;

vide a recess-into which this holder projects from above. The holder90 is secured to the upper wall of the casting 82 by a plurality of four slides 88on each side which are farthest the heel end faceof the shoe are mounted in contiguous relation to one another, while the other slides, which are in locations "where the edge ofthe shoe bottom presents a more pronounced. curvature, extend outwardly in somewhat divergent relation to one another, portions of the holder 90 extending upwardly between these divergent slides as far as the upper wall'of the casting 32. It

will be observed that the inner edge 93 ofthe upper wall of the-casting 32 terminatesat a considerable distance from the heel band 34, toallow for opening and closing of the heel band and for the operation of the machine on ;-lasts and uppers of different sizes, and the inner end portion 9.4 of each of the slides 88-is offset to extend upwardly into the space thus screws 92. It will be" understood that the vholder 90. is formed tov provide slideways along which the several slides 88 are IHOV-I sure of the coprovided and into substantially contiguous relation to the wiping face of the adjacent wiper 86, this portion of the slide extending inwardly along the face of the wiper into position for engagement with the heel band. Below these offset portions 94 of the slides are recesses in the slides into which projects a strip of leather 96 which is fastened to the heel band and extends around it in overlapping relation to a portion of the container 84, the slides 88 being formed to bear against this strip as well as against the portion of the heel band which is above the strip. In this manner the heel band is supported at all times in operative relation to the other parts, with provision for its convenient removal when it is necessary to substitute one band for another, sprin s 98 (Fig. 7) being further provided to connect front ends of the band yieldingly and detachably to the casting 32 and to open the band when conditions permit. Each of the slides 88, furthermore, has an outer end portion 100 formed to receive the pressure of the container 84 and extending downwardly into a recess in the holder 90, so that while there is provision for such movements of the al slides as are necessary to apply the required pressure to shoes of different sizes, these movements are limited to prevent objectionable displacement of the slides when there is no shoe in the machine. Extending around the outer ends 100 of the series of slides 88 is thin flexible strip 102 of spring metal which transmits the presiner 84 to the slides while uarding against damage to the container rem direct contact with the ends of the lid es. This strip is secured by a screw 104 ig. to that slide 88 which is located di- 'ectl opposite the middle of the heel-end ace of the shoe.

With reference to most of the slides 88, the construction and arrangement are such that the area of the surface of each slide that L the set er presses inwardly on the heel band 84 and the strip 96 is substantially equal to the area subjected to the inward pressure of the container 84. By reference to Fig. 9, however, it will be seen that the two slides 88 there shown which are located farthest from the heel end face of the shoe are so formed that their cute; end portions 100 extend downwardly farther than those of the other slides at the side of the heel band and accordingly present surfaces of greater area to the action of the container 84 than the ends of the other slides. It will be understood that this construction th same at the opposite sides of the heel band. The pressure-receiving surfaces of the two end slides at each side are accordingly greater in relation to their pressureapplying surfaces than is the case with other slides located farther rearwardly, although the increase in the area of the pressure-receiving surface of each extreme end slide is partly compensated for by an increase in the area of its pressure-applying surface, as hereinafter explained. By reason of this construction a greater pressure is applied to the upper portion of the heel band in locations near the wings of the counter to spring these portions of the counter inwardly and conform them as required to the contour of thelast which curves somewhat inwardly in thoselocations. It will be seen that the ends 100 of the two end slides at each side extend downwardly as far as the holder 90 does, and to prevent damage to the container by contact with the lower faces of the ends of these slides, a flexible metal strip 106 is inserted. It will be understood that the end portions of the strip 102 previously men tioned, which is omitted from Fig. 9, are enlarged sufficiently to cover the vertical end faces of the portions 100 of the two end slides 88 at each side.

Another portion of the upper which it is necessary to subject to especially effective pressure in order to shape it properly is that portion adjacent to the back seam. To assist in applying the pressure in this location there is provided a metal strip or finger 108 (Figs. 3 and 4) which is curved similarly to the heightwise contour of the heel end face of the last and may be somewhat resilient, this linger being positioned between the heel band 84 and the rubber container 84 in a recess o (Fig. 10) formed in the container. The finger 108 is secured by a screw 110 to the same slide 88 in which the previously mentioned screw 104 is located, and the outer end portion of this slide is extended downwardly in the same manner as the outer ends of the two slides at each side that are 10- cated'farthest from the end face of the shoe. Accordingly the finger 108 is not only sub jected directly to the pressure of the container 84, but is also forced inwardly in addi tion by the considerable pressure applied by the container to that slide 88 which carries the finger. Furthermore, the metal finger serves as a reinforcement of the flexible heel band and thereby assists materially in removing surface irregularities in the portions of the upper where the back seam stitches are located.

From the foregoing description it will be seen that the slides 88 constructed and arranged as described provide means for transmitting the pressure of the container 84 effectively to the portions of the heel band 34 that are located near the edge of the shoe bottom, whatever may be the size or shape of the last, while at the same time avoiding any objectionable interference between the flexible container and the wipers and serving also as effective means to confine the upper portion of the container in locations near the heel band and the shoe. Although the container, as will be evident by reference to Fig.

8, exerts some upward pressure on the slides 88, these slides are e fiectivelyfheld again t such pressure bythe upper wall" of, the castingj32 'so'tha't they do not. bear with undue pressure on the wipers 36.4 Y i IThe'endmost slide 88 at eachs-ide of the pressureeapplying mechanism is provided with anextension 112 (Figs. 9 and 11) to 7 press on the 'strip 96 of theheel-band in a location farther from the heel-end face of the shoe than the main portion of the slide, as

" may be; desirable in operating on some sizes or styles (if shoes. [Below the'extension 1-12 .the slide carries a thinplate 1 14 arranged to enter slot'11'6 in the manner 90 to confine the" 'container 84 in thislocation against bjectionable upward expansion; Secured on the casting 32;by oneofthe screws 92 adjacent to each of the end slides 885 is. a plate 118 (Fig; 7) arranged to bear; on'theupper edge of the extension 112 and also to overlap a portion of the inner end of the slide to assist in holding the slide: from being cramped'by the upward pressure ofthe 'coni tainer beneath'it.

With referenceto Fig.58 it will be seen that the plate 86 on the lower face of the cast ing 32, which serves'as the-lowerWall of the receptaclein which the container 84 is mounted, terminates at 122 at a considerable disi tance from the heel band and the shoe,jsimilarly to the upper, wall of the receptacle. In order to confine the flexible, container .84 against excessive downward expansion in the recess between this .lowerwall and the heel 7 band, there is provided a flexible strip 124 which .may 'be conveniently made: of leather somewhat more flexible thalnfthe heel band 34 l and is molded to provide a p'ortionextending upwardly between the container and the heel bandaround the end and along the sides'of; .the heel band andialso to provide a portion extendinghorizontally outwardjinto a recess 125 in the plate 86. At the extreme rear end. of the shoe this stripis cutaway to clearthe metal finger 108,'asindicated in Fig. 3. The outwardly extending portion of the strip 124 i'sfsecuredto thin metal plates 126 which lie onthe plate 86b'etween thisplate and the container 84 andare slidable inwardly and outwardly on-the plate 86. Any suitable -numberof plates 126 may be used for the purpose lustrated in Fig. 8, and a plurality of other in view, including a plate at each side, as ilplates located opposite the more sharply curved portions of the heel band. Portions of the several plates 126 may, if desired, he

As the pressure increases the strip 124 is gripped firmly between the container. and

theheelband', 'and the' strip'and the plates 126also' are pressed hard against the plate "86,s'o that the'portion of the container which is over the space between the heel band/and the edge 122 ofthepl'ate 86is held: effectively against undue expansion.

'(Fig. 6) mo-re particularly hereinafter described, and lea'ding'from the valve 162 tothe container 84" is 19a pipe 164 which extends lower end of a valve casing 150 mounted. on

through a recess provided in the cylindrical portion 38 of the casting 32 and also through a slot 166 3) in this casting. Against the inner and outer faces of the rubber container 8% around the inner end of the pipe 164 are secured metal disks 168 to prevent expansion of the container into the slot 166.

The pipe 148 is in communication with an opening 170 (Fig. 5) in the valve casing 150, and for controlling the admission of he compressed air to the container 8% a ball valve 172 is arranged to cooperate with a valve seat 17 at the upper end of the open-- ing 170. For controlling the release of air from the container there is provided a ball valve 176 arranged to cooperate with a valve seat at the entrance to an opening 17 8 in a nipple 179 in the casing 150, this opening communicating with the atmosphere. The two ball valves 17% and 176 are pivotally connected to opposite ends of a lever 180 within the casing 150, and extending upwardly from the valve 176 through the opening 178 is rod 182 which is pivotally connected its upper end to the rear end of lever 181 pivoted on an extension of the casing 150. The lever 184: extends forwardly along the wiper-operating lever 1 1 and is provided with a handle 186 arranged to be engaged by the operator with the same hand with which he manipulates the lever 44, so that while controlling the wipers the operator may at any time admit compressed air to the container or release it therefrom. A spring 188 is arranged to exert a downward pull on the end of the lever 184, so that normally the valve 172 is in closed position and the valve 176 in open position. Then the operator depresses the handle 186, the positions of these valv s are reversed, so that the exhaust outlet 178 is closed and compressed air is admitted to the container 8 1 through the pipe 156. To enable the operator to release the handle 186 without releasing the compressed air from the container, so that the operator may be free to use his hand for other purposes in the lasting operation while the pressure on the heel band is maintained, there is provided a latcn 190 which is pivoted on the hand lever 1 1 and extends upwardly through a slot in the handle 186, this latch being controlled by a spring 192 which acts to swing it into latching position when the handle 186 has been depressed far enough. This latch is in such a position that it may be conveniently manipulated by the operators fingers to release the handle 186 when desired. To enable the operator conveniently to release the compr ssed air from the container without the necessity of reaching for the handle 186, as may be convenient at times when he is not manipulating the lever 1 1, there is pivotally mounted at 19 1 on the head 28 a lever 196 which is arranged to engage one end of a rod 198 slidingly mounted in the casing 150 and in lug 200 on the lever 1 1, this rod being shaped at its end to engage the latch 190 and move it into position to release the handle 186 when the lever 196 is moved in the proper direction. A spring 202 on the rod 198 assists in maintaining the rod normally in its idle position.

In order to guard against possible damage to the air container 8 1 by admission oi' compressed air thereto when no shoe in position to receive the pressure, the previously mentioned valve 162 is so constructed and controlled as to close communication between the container and the manually controlled valve 172 and also to maintain the container in communication with the atmosphere at al times except when a last and shoe have been carried by the shoe support into engagement with the heel band 34. The valve 162 is retatably mounted in a coupling member 204; (Fig. 6) which is provided with ports 206 208 in alinement with each other communicating respectively with the air conduits 160 and 1641-. The valve 162 has a passage 210 extending through it and arranged to aline with the

ports

206 and 208 when the are in the positions indicated in the drawings, at which time the shoe is in position to receive the pressure. At right angles to the passage 210 in the valve is another short passage 212, in communication with the passage 210 and arri god to aline with the port 208 when the valve is turned 90 in a clockwise direction i -om the position indicateo in Fig. 6, at which time one end of the passage 210 in the valve will communicate *ith a port 21 1 in the member 20 1, this port leading to the atmosphere. It will, coordingly, be seen that when the valve is in this position the port 206 lead to the manually controlled valve 172 is clr ed and the air container 8 1 is open to the atmosphere, this being the condition when no shoe is in position to rec ive the pressure.

For controlling the valve 162 there is provided a horizontally movable yoke member 216 comprising two substantially rectangular portions spaced from each other oppo site sides of the coupling member 20 1 and supported upon an extension 218 of the valve 162, this member being further guided in its movements by a bar 220 which is fast on a plate 222 secured to the head 28 and has an end portion extending upwardly betwee V the two opposite side portions of the yoke member. The yoke member 216 carries a rack bar 22% the teeth of which are in engagement with teeth 226 formed on the valve extension 218. lit will thus be seen that as the member 216 is moved horizontally one di rection or the other it turns the valve to one or the other of the positions above mentioned. Springs 228 connectel to the yolre member 216 and to the plate 222 tend to move the yoke member toward the left and thus to 'inaintain thevalve162 in the position is which he'port 206 is closed andg-the aircontainer Q through an opening provided 'in the heel band 34 and in the strip 124'into position to isopen to the atmosp l 1ere.- Formoving the yoke 'member n the oppos te direction to position thevalve as indicated in Fig. 6, a;

be engaged by the" shoe or last as the shoe support is moved to carry" the shoeinto'the heel band. It will thus beseen that the yoke member 216 is moved toward the right by from that position.

the pressure of thework on the member 232 as thelwork is moved into operating'position, and that-it is moved toward the left bythe springs 228 when the work is withdrawn By this means insurance' is afforded that, regardless ofany mani ula'tion accidental or otherwise of the valve controlling lever 184, no compressed air will beadmittcd to the 'aircontainer unless a shoeis n position to receive the pressure. p c c V o ,7 In the operation of themach1ne,br1efiy summarized, the operator mounts a last with its shoe materials on the heel pin 50 of the shoe support, movesthe heel carriage 'toward the shoe into position to beiheldby the latcn 22 in engagementfwith the plate 24, raises the last and shoe approximately to the 7 height required by depression ofthe treadle and the yoke member 216 turns the valve 162 into the position illustrated'in the draw ings,thereby closing the communication be- '66, and by means of the hand wheel 63 moves the shoe support 54 to carry theshoetoward V thejheel band 34 and to force its heel end face againstthe heel band; As the shoe is thus moved towardthe heel band its heel-end face engages the member 232 on the end of thebar 230 and by movement of this bar tween the air container 84 and the atmosphere through the port 214;;1nd'open1-ngcommuniication' between the container and the 30 pe 160 leading to the valve casing 150 and the manuallycontrolled valve 17 2. The air container 84 is, "however, still maintained in communication "with the atmosphere since thevalvc 176in the valve casing 150 is held in open position by the action of the spring 7188 on the lever 1 84,. 7

Thereafter, in'the lasting of the heel end of the shoe, the operator depresses the handle 186 of the lever 184 and thereby admitscompressed air to the air container 84 through the valve 172 from the compressed air reservoir 142, the valve 17-6 being: mioved'to its closed position simultaneously with theope'ning ofthe valve 172; As the-air" container is expanded by the compressed ai r it torces the heel band 34 inwardlyal l around the-hee'h end-portion of the shoe, acting on the upper portions ofithe heel hand through the series of slides 88 which prevent contact of the air container with the'wip'ers- 36rand alsocone fine portions of the container near the heel band against upward expansion. Atthe extreme rear end ofzthe shoe. along the back scam the pressure is'.applied through the metalfinger 108 which is press-ed against the heel'bandibythe expansion of the air cone 1 band and is gripped between the container and th'e h'eel band and-also between the containeriandithe'plate 86 to hold it-effectively in operative position@ After admitting com -r ,pressedair to the air contamer-theoperator moves the wipers 36 to'wi-pethe marginof the upper inwardlyover the insole by 'mov ing the hand lever 44 with the same hand which he controls the-lever 184, and if desired, he may fasten the lever 184 imposition on the heel band by-means of the latch190. He inayalso at any time-release the compressed air from the container if he finds it desirable to do so in order to enable him better tomanipulate; or adjust portions of the upper materials; If 'he should desire thus to release the pressure atiatime when he is not engaged in m-anipulating the lever 44, he maydo so without the necessity of reaching for the lever. 184 by movement-of the lever 196 which extends into a position comparatively'close to the shoe; Y

After the lasting ofthe'heel end of the shoe'has been completed, the operator rel'eases the compressed air fromthe air container by permitting the lever 184 to be re: turnedfto its normal} position by the spring 188, andthereafter thepartsof the machine are returned to their starting positions. As

to maintain the pressure of the air container the shoe iswithdrawn from its position within the heel band, the springs 228 returnthe yoke member 216'to its normal idle position, and bythis movement of the yoke. member the valve162 is=turned to a position in which it closes the port 206 leadingtothe valve 172 andopenscominunication betw-een-the pipe,

164 and the atmosphere through the port 214.

It, therefore, the lever 184 should at. any time be depressed,accidentally or otherwise,

with no shoe in posit-ion to receive the pressure,-the compressed alr would nevertheless not'be' admitted tothe air container by reason of the closingof the p'ort'20'6 by the valve 162. 5 This insures against danger of possible damage'to the air'container through excessive expansion. '7 1 while the invention is herein illu trated as embodied ina machine :for shaping upit is not limited to machines in which a last is used as the inner shaping form, and the term form is accordingly used in many of the claims in a generic sense to designate the member over which the upper is shaped, whether it be a last or a form of a different character.
