` smolainis. L(o1. 12-33) In attaching a sole to a'shoe lhaving a welt I extension, it is necessary to support fthe Welt, at least around the forepart and outside shank portions of the shoe: tofprevent bending` of the'welt y under-the influence of thesole attaching presi sure; to ensure that the Welt is inintimate con-` tact with the sole, and that they are held together with sufficient pressure `to obtain awgood adhesive bond.` Prion sole attaching devices have` provided WeltA supports, :but Such supports have', however, simply beenadditions to conventional forms 0f presses and as they are llocated above the sole pressing pad theyfinterfere'with an operators vision; thus making it extremely difficult to. see that the-shoe isfproperly'located withrespect to the sole pressing pad and; thatthewelt support is in properiengaging relationwithv the welt crease of the shoe. Y l U v f Such previous welt supports have` alsofy been diflicult to adjust vto the size and shape-of the shoe being processed and generally, attempts to provide simpler adjustments have so encumbered the press that placementofa shoe is made'a slow and painstaking operation. f 1 A i i The present invention provides an improved sole attaching press havingas one feature', novel form of Welt support which is adapted to enter the welt crease ofa shoeplacedvthereon while allowing adequate visibility of-'the complete p shoebottom. f i .il l

Another-feature is the provision of eiiicient mechanism for adjusting the welt-support to con'- form to theshape and size of the shoe being operated upon and which does not interfere with anoperators vision lor `restrict easy placement of ashoe into the press.. 'f 1 e ,-:Other features of -the invention are the` provif sionxof simple .and eicient mechanisms whichY allowz. a Ashoeto be placed upon the weltsupportin an inverted. position while the sole pressing" pad is in a remote position; pressureresisting .membersto befbrought into properengagement spacing rthe shoe contacting #pressure resisting members* f i W il Still another feature. isthe provision of a single-control'for allowing thev shoe contacting prestsure resisting members to move to or away from the shoe; for locking them in position! and for conforming a portion'of thefweltlsup'port to the shape of the! shoe.

An lobject. of this invention production of cemented' weltshoes by providing improvedapparatus of simple construction which can be used effectively and eiciently to adhesivelyrattachtheoutsoles thereto.f

Another 'object of the invention'is to provide apparatus 4for use in attaching soles to welted shoes ofvariousshapes and sizes 'and which will give uniform results, 4highproduction and ease of operation. f'

\-Afurther object'of the linvention Vis to provide an improved welt support -whichjisrigid enough to resist the sole attaching 'press'ure andyet which has the flexibility to allow `vit to curve in twoplanes so that itmai7 be adjusted to accommodate a. -completerange of--shoeisizes `10ther -features and `objects off thefinvention willy inV part -be obvious and "willfin part appear hereinafter.` The 4invention accordingly `comprises the featuresof construction; lcombination of elements, and arrangements Vof partsy which will' be exemplified inthe construction'her'eim after set forth `and thescope of,` the'application of which will =be indicated in thegclaims: y

Asfthe hand wheel 43 is adjustedI to set vthe welt. support to'size zand/'to space the .toe supportA 66, the inside ballportion of the weltv sup- I thatit movesiwiththe bracket 60. VA bell crank n |02 is.pivotedlat:|`03 to a bracket|04 secured by the screws y|05 to the press base I5, and the short arm4 |06 of .the bell crank lever carries a -8 spherical roll |01 which engages with the cam |00; "The :long arm |08 of z the' bell V.crank lever has a .pin |89 which .engages with. a vertically .l 1

secured by the screws II4 vto the welt support platen 22; Thus as the bracket 68 is moved rearwardly, thebell crank= |02 is turned vclock-- wise on its pivot asviewedin Fig. 6 and the Welt supportat the inside .ballv point is positioned for a.A largeshoe, and movement of the bracket 60 forwardly for asmall shoe also adjusts it inside thefball portion of the welt support for a small Prior to placing a shoe Vin position vuponithe welt. support, `the handle 84 is pushedforward to lower the toe and heel supports as described. i The shoe` is then .placedo'n the welt support and4 pushed forward s'o that itengages in the welt and 14 may be locked `in position 7without .undue lost motion and also Vso that the ,ratchet teeth can be made vstrong enoughtowithstand the pressure applied thereto;` To liftthe pawls 10 lout of-engagement .with the ratchet teeth, a linger 89 is secured toeach of the pawls 69 to contact the extension 1|.'of the pawls 10. l .I

To properly `space-the toe and heel supporting members 56 and 66v according to fthe shoe size to be inserted into .the\press,f the bracket' 60k as previously described, is y,movable along .thev ways 6|,vand movement of this bracket 6I!` is accomplished simultaneouslyY with the adjusting of the welt support. vTo accomplish this, acam p1ate.45'is formed on the hand wheel 43 `and has cut therein a cam-slot` 90 which `engagesfwith a roll 9| secured to` an arm 92 of a leverl 93, pivoted at 94, to alstationary .support 95 held on the rods I9. The otherarm 96 of the lever is connected bya clevis pinf91 to one end of a link 98, and the other end ofthe link 99 to thebracket v60". Y
