lhere is a eoninion type of ironing 1nachine in which the work 1s passed over the .top ot a steani chest under ascri of rollers,

, the work enters the machine.

backy underneath and in Contact with the kled while travellingl back andforth nn-` derneath the` chest, andA therefore requires further treatment before it is ready to be delivered to the customer. lhis dilliculty so pronounced in tne `case ci" starched work that in seine laundries these machines are not Vused on any work except that which is nn# starched.

The ob ect oi the nresent invention is to provide a simple and novel attachment for machines of the type just described which will insure the work, whether starched or not, will leave the saine in a snioothxunwrinkled condition.

j lt is cnstornari, in machines oi this type,`

tohave a number of endless stringsor narrow tapes, to which we shall refer as cords, pass` n0 along` the chest underneath the roll fs and back across the tops ofthe rollers,`to serve as belts to hold the work on thefchest in the gaps,between` the` rollers. We have found that the problem o' overco1ningwrin` klang while the worl 1s carriedalong by the p aprons may be Asolved by employingsilnilar cords throughout the entire distance `that,

is travelled by the work in passing` back and V'forth underneath the chest. rl`he cordsnnder the chest may conveniently be continuations of those already in use, `se that there will be afsingle set of endless cords having portions above the chest to function as heretofore and, inladdition, otherportions'tha't insure that Y the work will be held dat while completing its travel after passing down from the top el the chest totheunder side.

The various features of novelty whereby ourinvention is characterizedwill hereinafter be pointed out with particularity 1n the claims; but, for a full understanding of our invention and of its objects and advantages,

and then, while held out of contact with the chest, to a delivernig; point `at the reference may be had to the following detailed description taken in connection with the :ifmfiinpanynig drawings, wherein:

F15., 1re l :is a top plan view ola machine equipped in accordance with our invention; 2 .is a side view; and Figs. 3 and l are which are which sir; are shown. aprons oi" about the saine width as the chest. rihe apron l gasses over a roll 5 lying in advence off the liront end cip' the chest, and over another roll t3 lj ing in rear ol and above the chest. The roll 5 is located at such an clevation that the upper ron of the apron will be in contact with the onder side of the chest. rlhe lower run of the apron passes over :L guide roll 7 at the rear end of and below the chest. rlChe apron passes over a roll 8 lyingr above and near the roll 5, over a second roll 9 lying below and forwardly of the roll 5, over a roll l() lying at sonic distance below the roll 7 at the rear end of the machine, and over a roll l1 lying rearwardly from the roll 6. All these parts are of old and well known construction. The work is fed into the front end of the machine between the right hand roller 2, in Figs, l and 2, and the chest, and is carried along across the top of the chest anddolivcrcd at the rearend ol the chest between the adjacent part of the apron 3 and the rear edge or side oi the chest; being carried alone; underneath the chest by the upper run of the apron to the iront end of the machine, where it is gripped between a part of the apron l and the apron 3 and is carried back between the two aprons to the rear end of the machine where it is discharged above the top olf the roll 1l.

Cords 12, serving the saine purpose as the endless cords heretofore employed, entend` `lengthwise o'l the machine between the roll-` I device comprises a long transverse rod or bar n 1:3 carried upon the ends of brackets la projectingirearwardly romthe trame l5 of the machine, a series of radial arms 16 fixed to the rod or bar and having their ends termi# hating a little above and not far from the roll 1l. Onthe free end of each arm is asmall guide wheel 17 rotatable about an aXis transverse to the machine. Each endless cord l2 extends from'the iront end of the machine over the steam ychest to the rear end, down the rear face of the chest, between the' under side of the steam chest and the upper run o the upper apron 3 to the front end of the machine, Varound the roll between the two aprons, back to the rear end of the machine between the lower run of the upper apron anl the upper run of the lower apron, over one of the wheels 17, and across the tops of the ironingv rollers to the liront end of the machine.

lnFigs. 3 manner in which the work is carried through the machine. A piece of work Avis slipwnj in the act of entering the machine in Hbo' a, un der the first ironing roller and between the cordsl)J and the top oit the chest. ln Fig. 3 the work' has' almost completed its passage over the top'of the chest and is beine` carried over` the rear tace of the chest and underneath the sameby the cords; By the time the work reaches the under side of the chest it is being pressed against the latter by the upper r'unorn the upper apron, so that itis carried. along underneath and incontact with` the chest to the 'front end of the machine where, as in the case of the piece of work B in Fig. 4, it is carried down between the aprons overthe roll 5. From that point, the

cords l2 now overlyingA the same, the work is carried to the rear end o'l' the machine between the lower run of theupper apronfand the lupper run of the lower apron. E lNhen the rear endl ,ot the machine is reached, the work passes beyond the roll? and up between the cords and the lower apron, as indicated at O in Fig. 8, to and overV the roll ll, where it is discharged romthe machine. v.

`While Awe have illustrated and described with paiticularly` only a single preferred vform of our invention, we donot desire to be limited to the enact 'structural details thus illustratedand described; but intend to cover all forms and arran gements which come with-y y l ab n s in thedeinitions ot our invention constitutf ing the appended claims.
