above a steam-heated revoluble drum or a y chest, andthe articles to beironed arefcaused by posedtransversely or the rolls. In order to'v avoid the use ot such s tringsjand the like/tor j properlyv advancing WOl, flexibleistrip?I er .fingers have been associated `witlrthe Letters Patentf.:[:]:1,186,640 and iny my prior U. SrLetters Patent: #1,7l0,980. Y

The present invention'relates more particu: larly to an improved form of stripper `'nger suitable for useas aforesaid; andit has forj its object to provi-de a moreeiicientstripper nger and one whichwill readily yieldwhen Y n encountering an abnormal `v`obstruction i and thus avoid becoming enmeshed with the work passing through the yironing machine. A urv ther object ot' lthe invention resides in theA provision of means Jfor introducingv a pre-fr 'determined resistance in the finger and which 39V must Arst be overcome before'l the linger will Y yield to pass an obstruction, thus insuringy against too frequent resetting .of the fingerv v which would result'if the yielding vaction were f asjdelicate as required withthe ordinarystrippertinger arrangement.'V A stillfurther object of the invention resides vision of a substantial and ruggedfstripper* finger and one which may be inexpensively manufactured. f

ityA of the novel fingers are arranged longi- .tudinallyfor1 a vroll as set lforth inthe atore'- 1 padding ormatted padding, is frictionally held thereon by being wound over the roll said Letters Patent; and each individual n ger comprises a blade of resilient material se#v curedl rigidly to a-support yat vits innerend, while yto its tree outer endl there is hingedly attached a tip member designed tov collapse toward the back of its carrying finger upon:

y improper functioning of the latten,` vFur-thermore7 apredetermined resistance f to'be'passed onward from one roll to thenext.. the use of a series of endless strings dis-Y..

in the pro-` j Incarrying out the invention, a multiplie-f' 1930. Serial No. 446,208..

is introduced toprevent collapse of theftip -untilsaid resistance has beenv overcome as,

for example, in'theprovision of yieldable ears at the sides of the tip and embracing the ad-v jacent side edges of the finger end. These ears have inwardly directed projections adapted for engagement with the said side edges and over which the edges must thus ride before permitting collapse of the tip. Lateral wings, also, are arranged to project at right angles from the sides of the tip substantially at its outer end; and the same'k have rounded edges ,adapted normally; to

guide and direct the'workbetween rolls as well as to ride smoothly upon a roll when said tip collapses.

'The nature ot the-invention, however, will best be understood when described in connection with the accompanying.;drawings, in which: j i f K Fig. 1 is a fragmentary transverse .sectionV through an ironing roll and associated steam] chest, showing the application of the novel stripper members thereto.

Fig. 2 is aA similarview illustrating a strip-y per member in collapsed condition; Y

Fig. 3 isa fragmentary longitudinal section taken on the line 8 3, Fig. 1.

Fig. 4 is a rear elevation of a novel stripper nger, on an enlarged scale; Fig. 5 is a longitudinall section thereof; and F ig.. 6 is an enlarged transverse section taken on the line 6 6, Fig. 5.

Referring to the drawings, 10 designates i one or a plurality of revolubly actuated ironing rolls such as are utilized in an ironingA machine, for example of the chest type, the Y said roll being journaled for rotationabove a steam-heated chest 11, the surface of which immediately beneath saidy roll is generally concave to secure greater ironing contact, A cloth covering 12, usually hair padding, wool with lapped portion 13 toA insure retention of the cover A on the roll surface. Guard or binder members 14care also associated with the roll to prevent the lapped portion workthe underlying cloth portion;

ing away from provided to kand stripper ymembersl 15 are material preferabl remove the Work from the roll surface as it asses from one roll to the next, all of which 1s more fully set forth in my copending application for U. S. Letters Patent, Serial No. l121,892. The said strippers are of narrow thin blades of flexiblen material suchas blue temperedribbon steel, and haye a securing arm at the inner end. The present invention, however, relates more -oopeoially tothe oonstluotononl; arf-.l rensomoetof tho. Stripper. members 71.5.@ Refs; erence being had particularly to Figs. 4 and 5 of the drawings, it Willibenoted -thata stripper member, contrary to the usual practice, carries at its outer andfree end a second-`K ary stripper element orn tip 16, the opposite ond ofthe', sllppormomber Ybeine' adopted to. be rigidly secured, for4` example, t'o iabarv o1;` boom, ,17 .oxtenfling longiwdnally-offo roll.
