Referring to the drawings, the machine illustrated therein, which, with exceptionsV to be noted below, is similar to the machine illustrated inapplication Serial No. 593,981, referred to above, has a friction roll for tensioning andoverdrawing the stock the lasting margin of` which isyieldingly pressed against an operatingsurf-ace II'of the roll, at two locations spaced circumferentially thereof, by means of a pressure member `com-prising a body portion I2 and a hinged part@ I4; 'a wiper, indicated by the'reference character I6; an edge gage roll I8; and a shoe-bottom rest 20.

The roll I0 is mounted on the lower end of a shaft 30 which is journaled in a bearing block 32. This block has a T-shaped arcuate rib 34 which is slidably mounted in a correspondingly shaped groove 35 formed in a supporting bracket 36, Figs.i

2 and 4. The bracket 36 is likewise providedwith a T-shaped arcuate rib 38 that is slidably mounted in a correspondingly shaped groove 40 inl a plate 42. As is explained'in detail in the above-A mentioned application, these arcuate'groov'es and ribs are so arranged as ytoj'perrriit the varying'of -the inclination of the shaft 30,- together with the roll I0, without altering the vertical position of the roll, and clamping boltsl 43 and 44 are provided f-or locking the bearing block 32 and bracket 36, respectively, after the roll has been adjusted. The plate 42 is secured to`a'slide`45 by means `o`f`a tongue 46 and groove 48 and clamping bolts -50 which pass through elongated slots inthe plate, see Fig. 2. When these bolts'are loosened the roll may be adjusted tow-ardor awayfroml the wiper |6.

The slide 45 `is supported in .a guide bracket 52 which is secured to a frame member 54. that is mounted on the top of a column 56 ofsuitable height, Fig. 1. A cam roll 5B, carried bythe slide 45, runs ina cam groove 60 formed' ina cam bar 62 which is mounted for vertical sliding movement 4 cal shaft 86 that is journaled in bearings 88 and 60 in .a gear housing 12 carried by the frame 54. The gear 82 drives, through -a reduction train comprising gears 92, 94 and 96, a shaft 98 that is l.likewise journaled in the housing 12 and which projects through its lower W-all. rThis shaft is connected to, the shaft 30, `which carries the roll I0, r'ine/an'sg-,off'an extensibleshaft assembly inv'dicated bythe reference character |00 and includ- ,ing universal joints |02 and |04. A sheet-metal Aguard housing |06 surrounds the extensible shaft fl'gas shown in Fig. 1.

The body portion I2 of the pressure member is secured; bymeans of a bolt I0, to the lower end of'an 'arm ||2 which is pivotally mounted on the bearings block 32 by means of a pin ||4 that exl. tendsthrough/flanges ||6 in the bearing block,

see Fig. 2. The bolt ||0 extends through lan elongated slot I I8 in .the body portion of the presswing in a c-ounterclockwise direction, and .toward sure member,v Fig. 3, which, when the bolt is loosened, permits adjustment of the pressure `memberlaterally ofthe machine and relatively to the roll' I0.v The hinged part I4 of the pressure member ispivotally mounted on the body portion I2 by means of a pin' |20 and is yieldingly urged to the roll| 0, about the pin I 20, Fig. 3, by means of a compression spring |22 which is fitted in recesses |24 and I 26 in the body portion and hinged part, respectively.` A rod |30 having a spherical end |32 is connected to the arm I I2 by aplate |34 and screw |36. This rod extends rearwardly of the machine from the arm I I2 and passes through an aperture |38 in a bracket member |40 that is secured to the frame member 54. Interposed between a collar |44, adjustably secured to the rod |30 by a set'screw |46 and the bracket |40, is a compression spring |48.

When the treadle, notV shown, is depressed, the

f-cambar 62 will be moveddownwardly, Aand the in the bracket by means 0f a treadle, not shown,

but connected thereto by :a treadle rod`64. Such' vertical movement of the cam Ibar 62,wll shift the bearing block 36 and roll |0 forwardly orrearwardly of the machine for a purposel Whichwlll presently appear. i

The shaft 3u, 'and m11 lo, are driven noma suitable sourceof pcwer,`not shown, thr'ughfa main input gear |8 which meshes with any idler gear 16, Fig. 1. 'Formed integrally with the Fidler gear 16 is another gear (not shown) which meshes e with a gear 82, secured by a setscrew 84 .to averti- 'following forward movement of the roll I0 which vspring |48. :contact of the vroll I0 on the pressure member,

The wiper It., which; is. ofnoveland improved construction, comprises a relatively thin disk which is` secured, by means; of screws |80, to `the endl ofa shaft,A |82 that is` journaledrin a bearing block;` L84 and whichA carries a` beltl pulley |86. 'Ehe `bearing block IBA is adjustably mounted; by means, of boltsv|8=1f and slots |88, on the lower end of, a `housing |80 that is mounted for angular adjustment about a boss 1| 92 on the lower end ot the housing .12, this boss being centered about theiaxis ofshaft 86, and clamping bolts |84 `are provided.` foi-"holding the housing andl wiper disk in adjustedt position. The shaft 86 carries a beitelfgear |93? which meshes with a bevel gear |94. mounted: on "a countershaft |96.` Also mounted on the shaftl ISE is a pulley |98 and a be1t280; runs. over this pulley, the pulley |88 and an. adjustable idler pulley 282. j

The; edge gage roll I8- is Journaled on a stud 21|I which is carried by al block2| 2 that is mounted fonadiustment; forwardly and rearwardly of` `the machine, `on an arm 2|8 by means of a clamping bolt 2|6` which passes through a slot 2|4 in the block, Figs. 2g 3 and 5. `The arm 2|8 is likewise mounted for adjustment,` laterally of the ina.- chlnet bi1-means ora clamping bolt 222 and slot Mumia bar12-24 and this bar is mounted for adjustment `vertically of the machine on a slide 238'; by means ofabolt 232and` a slot 234. The

slide 236i i`s`1 mounted for reciprocating movement in a"`gui`cleI bracket, notshown, but similarfto 1the bracket 52 and secured to the frame 54. This slideis moved forwardly and rearwardly of .the machine by the cam bar-v62 when the treadle is operated in theA same manner as slide 42, as is explained in detail in the abovemennoned application, Serial No. 593,981.

The bottoni rest is mounted on the bearing block32, for angular adjustment about the; axis ofthe rolll, by means of an arcuate boss 1240 on the hearing blockand' a bolt 242 which passes through a slot 244 -formed inthe upper end of the bottom-resnsee Fig. 1. Y

The operating surface of the wiper l'is formed by? a plurality off circumferentially disposed. axially offset, helical ribs 308: The leading ends of these ribs are rounded`,`as indicated at 302, Fig, 5, andeach leadingend is substantially in axial alinement with the trailing end' 34of the next preceding rib so that a circumferentially` continuous wiping surface` is presented to the work, see Figs. 3 and 5, and one of the ribs isv always in contact with the work. The effector theroulided leading ends 302 as, theystrikethe lasting margin is to produce a hammer-likehiow which greatly augmente the action of the wiper in causing adherence ofthe stock to the shoe-bottom member.

However, by arranging the leading ends and `traillng endsof the ribs in` axiallalinement, asabove pointed out, any tendency for the rounded` leading ends to strike` and break downthe edge of the shot-bottom member, herein illustrated as a platform. P, is avoided. The rounded leading ends are formed as continuations` of semicircular recesses 306 formedin the side facefofl the disk.

`...The illustrated machine operates generally, in the same manner as the machines of ther application, and `.patent mentioned` above, and withthe treadle. depressed.. the lasting. margini. on the stock .is pressed; against the operating surface? lll r llilbyl" the` portions 1|i2fand1il4'. ofvtl pressurefmember and; as airesult ofithefrictioml drag impnsediionithelstockby-the roll', thestock is tensionediitsflastingmarsin drawn inwardly from* thezodge" of the shoe `bottom and over: the

In the manufacture of certain types of platform shoesthe platform covers are madefrom'strip material the lasting margin of whichis ycoated with adhesive in a non-tacky condition;also,the adhesive whichV has been applied to the'` platform cover or other stock to be lasted maypn some cases, be permitted to dry for too long a period so that the adhesive reaches .a non-tacky condition in which it will vnot adhere satisfactorilyy if at all, to the shoe bottom member upon being wiped in and pressed down by the Wiper. It has been `found that by applying heat to the `lasting margin of stock of this type during the lasting operation the adhesive may be lrendered tacky and a satisfactory lasting job accomplished. I For thus applying heat to the stock, in theconstruction shown in Fig. 4, the illustrated machineis prlovided with an electrical heating unit'v 150B, which may be a conventional plug-type heatingunit, that is press-fitted into a bore 502 in the body portion I2 of the Vpressure member.I `From this heating unit leads 504 and 5ll61extend to a suitable source of electrical energy,.not shown. During the operation of the machine in lasting the stock, sufficient heat from the portion I2, that is heated by the unit 5|.'III'` and which presses the lasting margin M againsttheroll I0,wil1ipene trate through the stock and render tacky, i. e.,

activate, the adhesive coating on the inside face thereof.l The degree of heating of .the body portion I2 will be only sufncient to activate the adhesive and not enough to scorch or otherwise mar the outside face of the lasting marginof vthe stock and any suitable form of thermostaticcontrol may` be used properly to regulate the action of the heating unit 500. While the heatingv unit is herein illustrated as applied to the modified construction of pressure member vin whichlv the hinged part I4 has been omitted, it will, of course, be readily understood Athat a similar heating ar-` rangement may be provided in the pressure membersshown in Figs. 2 and 3 and which arel provided with the hinged portionv I4. u

The action of the rotary wiper I6 in -laying the overlasted stock smoothly down on the shoe bottom may be improved by heating the wiper. This may be conveniently accomplished inthe man-` ner shown in Fig. 4 in which a block 5I0'having a flat side face 5I2 and provided with an elecrical heating unit 5I4 is adjustably mounted on the bracket 36,by means of a support 5I6, bolt 5I8`ands1ot 52D, ear 522, and a clamping bolt 524, so that the side face 5I2 may be"positioned close to the side face of the wiper.v This heating unit, which is connectedto a`suitablesource of electrical energy, not shown, by means ofl leads 526 and.52, rwill radiate `sufiicientheat tothe closely adjacent wiper to keep thewiper-itself warmed to a point Wherethe helical ribs 300 will have a heated ironing action on the over# lasted stock which is quite effective in lsr'noothin'g the stock and removing wrinkles therefrom.v
