This invention lrelates toshoe-pressingmachinessuchfas are'nsed, for example, to apply shaping pressure to the outsoles of shoes on their lasts, this application being,zin part, a continuation of my copending' application' Serial No. 82,029., filed on January 18, 1926.

i that :cop'ending application thereis dis closed :a method of shaping-or leveling outsoles by difierent treatment at-the forepart and theshank respectively, the forep art being leveled .by rolling'pressure and the shank by pressure :applied to 'all portionsfthereof substantiallyzsinrultaneously. As therein ex planted, the use of pressure of that character applied in the-shank portion of the shoe by means of a suitably shaped pressing member or pad is especially advantageous in the V mmufacture of Womens-shoes of a type in the shank are thin and-are which the'transverse shank curvature of the shoefzbot-tom is comparatively great and in which the-edges offi'the soleat the sides of against the upper.

' ob'ect of 'the'present invention is to providegeffective means for thus shapingthe shank sport-ion .of the sole, the term shank beingusedherein to include-a portion sometimes Ieferredto as the Waist; In womens shoes -ithere 1s usually a pronounced upward slope of the. shoe bottom at the rear of the ball-line, and iniview of that condition the.

invention ,provides a novel organization including means for applying sole-shaping pressure to the shank in adi-rection inclined forwardlygtoward the 'forepart of ithe shoe respect to the direction of the height of the shoe, so that thepressureon portions of the sole :immediatelyatthe rear of the balls line will be especially effective to impart to the sole the desired transverse curvature and to pressfits opposite edges close to the upper. The invention is herein illustrated in its applicationsto a type 'ofmachine shown and described in Letters Patent No. 1,549,243, grantedknpon my application on August '11, 1925, that type of machine comprising a jack which engages the last or shoe at the heel end andforwardly-of'theheel end to support-the shoe against upward pressure .on itsbottom' '50 face, and a sole-pressing member-or pad.

Machines of the yp mted in the La;

ters .Patent mentioned are twin machines, compris ng. duplicate -mecl i anisms whereby one shoe is subJeCted to pressure simultaneously with therelease from. pressure of another shoe previously ope-rated upon. Only' one of such mechanisms is herein illustrated or need be referred to for an understanding of the present invention. "As shown in Fig.1'

1, and as more fully illustrated and described in said Letters Patent, the machine is provided with a pair of vertical rods 10 on which there is adjustably secured acasting 12 which serves'as a support for downwardly extending arms 14 and 16 of a shoe-supporting jack, the'arm 14 having thereon at its lower end a pin 18 for engaging the heel end of the last in its spindle hole, and the arm 16, as herein illustrated, being'provided for purposes Of the present invention with means more par-' ticularly hereinafter described for supporting other portions of the shoe-and last against the pressure applied onthe sole. Mounted for verticaljfsliding movement on the rods 10 is a carrier 20 provided with means at its opposite sides for supporting apair of trunnions 22 fast on a pad b0): 24 on which is mounted apad 26 for applying pressure to the bottom of the shoe; The meansfor imparting operativemovement to the carrier 20 is not shown in detail, but is fully illustrated and described in the'above-mentioned Letters Patent. It will be understood that the shoe ismo'unted on the jack bytheoperator when the' carrier 20 andthe pad 26 are in their lowermost positions, and that in the operation of the machine the pad is moved upwardly to apply pressure to the shoe, after which the machinecomes to rest, and that in the. neXt'ope-ration of the machine the shoe is released by downward movement :of the. pad simultaneouslywithrthe; application v ofpressureto ashoe by thejother twinmech anism. a, V w V For purposes :en 'agin g pin 18 on the arm'l l ispositioned 1 3 t i inventi th i 1 S at such a height relatively to the shoe-engaging means on the arm 16 ithatthe shoe is presented at a substantial inclination to the direction of upwardmovement of the pad 26, with the forepart of the shoe upwardly inclined, so that the pressure of the pad 26 on the shank portion of the sole is applied in a-direction inclined forwardly toward the forepart ofthe shoe, the arrangement thus being suchthat in operating on ,shoesof a style in] which thereis'a comparatively sharp upward inclination of the sole'fiom'the ballline toward theheel-seat the 'pressure is applied'to portions of the sole at the rear of the ball-line-in a general direction substan :tially perpendicular to the direction of such upward inclination of the sole. As herein illustrated, the pad 26 is'soformed thatit is limited substantially to engagement with the shank portion of the sole, and'asindicated at 28 in Fig. 5, moreover, the pad is shaped to accentuate the pressure on the opposite side'portions of the sole and thereby insure that the 'edgesf'of the sole willbepressed closely against the upper. (See Fig. 3.) The V pad is preferably so formed that at each end of its shank engaging portion. it presents a any slight-engagement of the pad'with por s'oleis concerned. The 'pad box 24 provides ELIlgld. support 'tionsof thesole located eitherforwardly orrearwardly of the shank portion will have no; effect as far-as altering the contour of'the i for the pad' and is free to'swing on the car rier 20 by means of its trunnions 22, so that the pad may adapt itself to the inclination o'fthe shoe. The rear end of the pad, more over, is somewhat heavier than the front end, so that-the pad box and the pad will assumean inclination approximately corresponding to the inclination of the shoe even when the par'tsof the machine 2116111 their idle positions' The pad is preferably'formed of rub-Q ber. and may, if desired, have. acovering of leather on its shoe-engaging face, as shown.

pressure of the shoe'on the padtends tomaintain'it in engagement--with the abut ment 3O.

Forisupporting' the shoe against the pressure on the sole, the arm'16 of the jack is er:- tended for a*considerable 'distzmce lengthwise of the shoe and is so formed as to provide an abutment fora molded rubber pad 38 arrangedto engage'the top of the shoe or last continuously from the hollow. at theback of the toe substantially to the rear'end ofthe instep portion of the la 'st,the arm and the pad having a contourlengthwise of the shoe 90 substantially fiat facetoward the sole, sothat' such as to conform substantially'to'the. contour ofthe'last in the location where the shoe orlast'is-engaged by'the' pad'r A firm support is thus provided for the last in llne with the pressure applied to the shank. by the pad 26 so as to insure against breaking the last un der the "heavy soleshaping pressure, esp-e} cially if the last'is a hingel'ast. Preferably 'the front end of the pad38 will beturned up awayfrom the shoe, as shown, toinsure against marking the shoe. IThe pad is preferably so formed that its shoe-engagmg face is straight'widthwise of the shoe so that the same pad may be usedforboth right and left shoes. The .pad is mounted on the arm 16 between downwardly projecting flanges 40 and 42 at the opposite sides of the arm, and is so formed as toextend laterally under the edges of the flanges to avoid any possibility of'contact of the metal arm 16 with the shoe. For 'holdi'ng'thepad in osition it is so molded as to 1 rovide ro- 7 jjections or lugs 44 on its sides which are received in openings formed" in the flanges 40. i and 42' The flange 42-is detachable, as'illustrated particularly in Fig. 3, to permitconvenientreplacement of the pad when re-, quired; I The-heel pin 18 is supportedona holder 46 which is pivotally mounted at 48 on the arm 14, and the holder 46 is controlled by a spring 50 which tends to tip the pin 18 in a forward direction, as common heretofore. It will be understood that when the last is I mounted on the pin 18 the pri 3 its lower end of: which is secured a member 56 r 14 and 16 to turn ab'eut axes extending widthprovided on its .opposite sides with arms connectedirespectively by'links 58 to the arms and 16, substantially as heretofore, :only 1 one of the links58 beingshown in the draw-- ings; By. this means the arms 14and" 16 are so connectedto each otheras'to constrain thernto move" either toward or from each other in unison. The mach-ine is further pro vided with means for adjusting these arms toward or from-each otherto accommodate the ack to-shoes of different lengths..' .For this purpose there isTprovided a screw 60.,

having right andIleft-hand threads thereon for engagement with corresponding threads formed in" cylindrical: members 62 which areswivel'ed in bearings'formedinthe arm's wise of the shoe. 'Byturning thersc'rewEGQ the arms may thusbe moved toward or from each other- It is desirable that after the arms have thus been adjusted for any particular size of shoe, they shall beheld rigidly against relative displacement in response to the pressure applied to theshoe. There is accordingly'provided means forlengaging thescrew 60 frictionally to aiford increased,

insurance against accidental turning movement; For this'purpose each of the members 62 is provided with a threade'dbore formed axiallythereof, in which is mounted a small block 64 for engaging the screw 60 frictionally and also a spring 66 which presses the block against the screw andthe tension of; which is adjustable by means of ascrew 68;

It will be understood that the pressure of the blocks64 against the screw 60'does not interfere with turning of the screw when it is required to adjust the jack, but 1 aifords sub-v stantial insurance againsttur'ning of lithe screw accidentally, forexample in response to the pressure to which the jack is subjected in the operation of the machine on a shoe.

The manner of operation of the .maohine,

including that of the novel features provided by the present invention, has'been sufliciently described in connection with the description of the construction andrequires no. further explanation.

It is to be understood that whilethe invention is herein. illustrated in" its application to a machine of the type shown in the prior Letters Patent hereinbefore mentioned, in its more general aspects it is not limited to machines of that particular type; and, further- .more, that'as to various novel details of construction disclosed, the invention is not limited to machines for shaping soles or for applying pressuret'o the shank the shoebottom exclusively.
