IRONING TEACHINE.

Application filed October 18, 1920. Serial No. 417,742.

Be it ltnown that l, iii/litiasis iiUMeLSNo, oit the city of '.loivinto,y of York, Province of Ontario, Canada, a suhject ot the King ot Great Britaim'have invented certain new and iuseitul improveinc its in Ironing Machines, of which thn tol loi fr is a specification.

invention relates to improvements in ironing machines, and relates more particularly to that class of machine in which a rotating roll co-acts with a heated shoe, and one oit the objects of the invention is to so poise the roll that the same may be readily moved against or away kfrom the shoe with the minimum ot eliort on the part oi the operator and thus avoid the necessityot the operator having to exert physical power to actually litt the roll or the shoe. The elimination ot-the necessity of having to physically lilt an element of considerable weight enables me to provide a machine which can be operated with the minimum expenditure ot energy on the part of the operator, and particularly in adapting my machine for domestic use l ind that a machine is greatly in demand which will not be as tiresome to operate as those wherein the roll or shoe is actually lifted. VAnother object et the invention is to so support the roll at each end that by reason of the comparatively snort movement to be given the same by the op erator when moving it against or away from the shoe, that there will 'be very slight wear on the supporting means tor the roll, and as this wear will be the same at each end of the machine, there will. be no possibility of the roll getting out of alignment with the shoe. The result is that goods can be more satisfactorily ironed, and by reason of the uniform friction of the roll against the shoe the cover therefor will be uniformly worn, and will consequently last longer than where more friction on one part will wear the cover out more readily in that particular location. A stillturther object of the invention is to provide a system of leverages so that the roll will be quickly positioned against the shoe, and an increased leverage in effect obtained, with the expenditure of the minimum of energy on the part ot' the operator, at the momentthe roll is exerting the greatest presrsure lagainst the shoe. A. still iurther obi ject of my invention is to Aprovide a system ot resilient levers (3o-acting with the roll tor the purpose set forth, so that the roll will be vheld against the shoe in such manner as to of the class set torth which will contain the minimum number of parts consistent with eiciency, and to so design the various parts that they may be assembled and adjusted by semi-skilled labour, and in the following specification I shall set 'forth the preferred construction, and what I claim as new will be set forth in the claims forming part ot this specification.

Figure l is Aan elevation of the righthand end of my machine, showing` the roll held against the shoe, and the train of gearing employed to rotate the roll. vFigure 2 is a view similar to Figure l except that the outer casing and train otl gearing have been removed to show clearly the lever mechanism controlling the movement ot the roll to and away from the shoe. `liigure 3 is a vertical longitudinal section on the line Figure l. AFigure 4 is a perspective view of the operating` lever mechanism for the roll at the righthand end of the machine. Figure 5 is an elevation of the lett-hand end of the machine showing the position of the lever mechanism when the roll is moved away from the shoe, and Figures 6 and 7 are respectively end and side elevations of the preerred form of stop used to limit the movement ot the lever mechanism, the latter view being shown partly in section.

In the drawings like characters of reference reiter to the same parts.

Suiiicient has been set forth to Vshow that .my machine is oi' that type wherein the shoe is fixed, and the roll is brought into and out oi' engagement therewith. Of course the shoe may be heated in any desired manner.

er and B are respectively the right-hand and lett-hand heads of the machine, and the same are carried after any suitable manner 2. lo an 'iroiiiiir` mziehhe. in eomhiT-mtion u, suitable trame e ihi'acioj ao end ifiemfoer et eaeh oud thereof; shoe carried off seid end m Arhers; a shaft; a. roll ou seid shaft which rotates therewith; u lever lriouted at each @iid of seid roll aud udegjjted to form hearings 'for said shaft and hating' 'pivotal association each with essoeiuted end member; n, roel; shaft mounted u1 said frame; an arm carried hy seid roch-shaft :at each end thereof; a link-member piro-teo 'to each of the said armst and each pairtl,n iii the form o2 an open frame having' au opening through the inner end thereof; a rofl operating through the opening in the immer end of each of the said "frames and each located with its longitudinal exis; in alignment with the longitudinal axis of' its associated frame-portion of said link members; means whereby the inner end` of each of said rods has pivotal connection each with its associated lever et a point above the longitudiml axis oi? said rook-shaft; e Washer loosely1 mounted on euih of' the seid rods :md intermediate the iimer end ol each of the said link-members and the means whereby each olf the said rods has pivotal eomieet' m with its associated lever; u coiled spring' mounted ou each of the said rods md Within the frame-portion et each link-member; u nut threaded on the tree end of eaeh ol? the said rods and adapteclto hold said spring; .in coaction with the inner end of each of the said frame-portions of seid liiil: members to permit the same to fum'tiou, and lever means mounted on said rock-Shaft to operate the seme for the purpose set forth.
