I the threadguide pulley, and Fig. 7 represents a detail central section of'the same.

The machine whichis generally represented 1n'F1g, 1,:forms the subject matter of my PatentNo. 990,564, April 25,1911, and consequently it'xwill not be particularly I described herein. j This machine includes, however, in addition totheparts to be more speclfically described hereafter, ith-read deliv ery mechanisms'l', thread winding mec'haelongated hollowbodynportion 4, and a cap i 5 therefor. 3

1A polishingband 6 is=removably secured attwoplaces on'xthe body portion of the heater by the. screws 7, 8. This band 6 Fig. 3 ;v and a coil spring9 is-mountedin the upper end of the body portion of the heater,

for yieldinglv holding the band 6 snugly in position on theheatert passes, over the cap 5, as'is well shown in Theheater is shown in the present instance as being fitted to be heated by steam, and, to that end, there is provided 'a main steam'inlet pipe 10'and a main steam exhaust pipe 11, the inlet pipe 10 being mounted within the exhaust pipe 11. Theexhaust pipe 11 has a branch pipe 12 which is screwed into the lower end of the bodyxportion 4"ofthe heater, as indicated at 13 while the inl'etpipe 10 has abranch 14 which 21' passes up through the branch 12 into the in-- terior of the bodv portion 4: of-the heater, and extends nearly to the top thereof.

The body portion 40f the heater is coveredon all exceptfone side thereof, vizf the r J? side on which the band 6 is mounted, with a nonheat-conducting acket 15 composed of materialsuch as asbestos fiber, and the pipes 11 and 12 are also covered in the same manner. V The purpose 'andeffect lot this no'nt1;

heat-conducting jacket is to prevent the outside pipes 11,12, and the parts of the heater with which the thread being polished does not come in contact', from losingv a consider;

able amount of heat through radiation; and thus a given degree of temperature may be maintained in the unjacketed side of the heater, viz: the 0116.011 whichtheband .6 is. heat ng mea mounted,with a less amount of; dium than has heretofore been required, owing to the fact that considerable heat losses have been experienced through the radiation from the steam pipes and. unus dportions of the heater.

.Tlheheater i soformcdthat one endottlie surface'on which the band 6 is mounted is wider than the other end-"of: thersaid. surface; in the present instance, the upper end of; this: surfacei's shown as: the wider one. The purpose of. widening out thlSzSlllffiCG at the top is in order to provide-suflicientroom for thethread which is: beingrpolished' to be 1 rolled: back: and forth on theband- 6 which conforms to the shapeof-this surface. In asmuch. as this rolling of. the thread is performed: by: thereciprocating rods 3 which are. located at.v one end only of the heaters,-

' it isr not necessary to makethe endof the heating surface whichis. farthest from the rodsi3. aswi'de as theu-pperend of thegsure faceslwhich are'near the rod It isdesirable, therefore, tomakethe lower end of the heating surface as narrow asis feasible'in' order tomake the heater lighter, avoid the use of unnecessary materialin the heater, and in particular obviate: any; wastejof ma terial in the-bandl 6 for the reason that this band. is commonly composed of aluminum which isquite expensive.

A threadrguide pulley-is mountednear one end oli the heater, in the-present instance: at they lower end of the heater, to which it" is secured-by a cap screw 16 This thread guide pulley comprises. flYCfl-Slfl'lf" 17 which has a pairof thread retainers 18:soarranged that thread may bepassed between them when it isdesi-red to do so whilepreventing the thread from falling out of line with the pulley wheel in; case the thread: maybe slackened for any cause. Vithin this: casing is a pintle 1 9 on. which is rotatably andremovablymounted a pulley wheelwQO: One end of the casing 17 is-open forthe'removal of the'wheel' 20' when-it is! desired to, clean or replace the same, and a cover 21 is pivotallysecu-red to thecasing 1,? by the screw 22;

which cover is: designed to normally'close the open end of the casing 17 The thread in the course of being: polished passes from the thread delivery'mechanism L downrin contact with the-band 6" on the heater, around: the pulley 20 and up again in contact with the bandit? totthe thread winding. mechanism 2:

By: the for-In and: construction of the heater and thread guiderpul leyhereinave described, there; is promotedva'n economy of .1 heatingfmedium, hence anecenomirof fuel about halfas much aluminumas has heretofore been necessary in making a polishing band for a, heater of a-given sizehaying means for holding the-band snugly thereon. The-arrangementofi the heaters in the machine sothat the thread passes up and down the front side of the heatenfpermits the heaters to be-placed closer together than; has

heretofore: beeny'customary, inasmuch as;

there "is little necessity ":of-=reaching in bee; tween 'the=-heaters; the placingnof; ithe thread:

guide pulley'on, thev front or the ;h eater with the cover 21 projecting out from; the. ma.- chine also permits the quick cleaning andgrre-l placement of the pulley wheeli20 without' the necessity of reaching in between the-theaters, 7

the, construction of the pulley 1 wheeli guide making the replacement very; easy and? rapid and: its location rendering it. convenient.

a The j'acketingof theapipes; and heatnr with non-heatconducting-material? not: only promotes the economy'of heating medium hereinabove. mentioned, but alsorabsolutel'y prevents the operator: from, burning his or her arm whenlt 1s necessary-to;in'sertthe arm in: between the-heaters, for instance, for thepurpose of-unscrewing the screwTtqre; move the polishing band,
