To all 'whom t may concern.'

Be it known that I, ALFRED K. MILLER, of Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Drying-Machines, of which the following is a specification.

This invention relates to a device to facilitate the handling and drying of yarn after sizing or other treatment which subse quent-ly requires a yarn drying process.

A drying method frequently employed is to-expose a moving horizontal stretch of yarn to an application of heat; the heat ap plication being made in various ways. A drying device based on this principle is desirable as the yarn is easily andled in this position. It is objectionable however because in traveling horizontally the unevenness of tension in the various 'strands is accentuated and such a drying device necessarily occupies considerable space. Devices for drying by applying heat to the yarn while moving perpendicularly are also used to some extent and overcome the ditiiculties presented by the d ing device acting on a horizontal stretch o yarn. The more serious difficulty presents itself in the second method however of get-ting the yarn ina succession of windings properly in place to wind through a drying machine or Slasher where the yarn passes in a sinuous course over elevated rollers or supports and under depressed rollers or suplports. The present methods of carrying t e initial ends of the various strands of each new winding under the depressed supports and over the elevated supports all entail much time and labor. The device here presented makes it possible to adjust the yarn preparatory to winding, in a horizontal position so that it is easily handled, through a. frame carrying but a short stretch of yarn and occupying but little floor space, and then by elevating some ofthe supports on which the yarn rests in its initial position, to raise the yarn so it takes a sinuous course, its stretches being nearly perpendicular. Other rollers in the horizontal frame of the machine under which the yarn passes in its initial position and alternating with the elevated rollers,'

cause the yarn to travel in alternation from the fixed rollers to the elevatedl rollers thus exposing to the application of heat extended substantially vertical stretches of yarn while drying the same.

Referring to the plan, Figure 1, is a longitudinal vertical sectional View of a yarn drying machine embodying my invention. Fig. 2, is a horizontal section on line 2-2 of Fig. 1, and a plan view of the part below said line.

MyV machine as here shown comprisesA a lframe w having at one end a sizing device 2 adapted to apply size to the entering yarn y, and at the opposite end a roll or beam 4 on which the sized yarn is wound, the threads or stretches of yarn being guided by a comb 13 and a roll 14 to the beam 4. Journaled in fixed bearings in the frame fw are a series of horizontal rolls or yarn guides 1, which are all at the same height and are so arranged that thc yarn passes under them and taking a straight course from the sizing device 2 to the guide roll 14. I term these the fixed yarn guides. Journaled in vertical guiding slots or ways 10 in the frame fw, are a" series of adjustable yarn guides 3 which nominally rest on the lower end of the ways 10 at points below the fixed guides 1, the relative arrangement'of the guides 1 and 3 beinosuch that the strands Q/ are adapted to be passed between the guides as indicated by full lines in Fig. 1, when the machine is being prepared for use. To the side members of the :frame w are attached two '.flexible cables 6, each cable being attached at oneend as indicated at 6, Fig. 1. The opposite end' of each cable 6, is attached to the periphery of a pulley 7 adapted to be rotated to wind up a portion of the cable upon its periphery, the pulley 7 being attached to a shaft 7 1 provided with a pulley 5 adapted to be engaged by a driving belt. The cables 6 pass over a series of elevated pulleys 8, mounted on rods or shafts supported by the upper portion of the frame, and under pulley 9 mounted on the adjustable guides 3. When the cables 6 are let out to the maximum extent they hang in elongated loops or bights from the pulley 8 as shown by full lines in Fig. 1, so that the yarn strands y are unall'ected by the adjustable guides 3. When the cables 6 are partially taken up by the rotation of the pulley 7 the said bights are shortened and the ad-` and pushed upjustable guides 3 are raised y, carrying porwardly against'the strands tions of said strands upwardly in the form up the strands and portions of the strands being dispersed in an elongated substantially rality of exea vertical stretch, arranged in close proximity to each other and adapted to be acted on by ascending currents of heated air. The shaft 7a is provided with brake drums 12 which are engaged by brake shoes 15 which are preferably bands or straps attached at 16 to the frame and provided with weights 17. The drums and weighted shoes are adapted to sustain the adjustable guides 3 in their elevatedpositions and permit the said guides to be lowered gradually to their initial position.

While I have shown a plurality of adj ustable guides 3, it is obvious that my invention may be embodied in a machine having but lone of these guides movable between two ixed guides.

The word thread or threads as used in the claims hereinafter set forth is intended to include woolen, worsted, cotton or other yarn.

Having thus described my invention what l claim'as new is,

1. A drying machine comprising a plu'- rality of ixed thread guides, an adjustable thread guide moving from a position on one side of the fixed guides to a position on the other sida-.means Jfor engaging and moving the leading ends of threads interposed between the lixed guides and the adjustable guide and means for thus movin the adjustable guide, to cause the said treads to take a sinuous course.

2. A drying machine comprising a plurality of fixed thread guides, an adjustable thread guide, movable vertically from a position below to a position above the fixed guides, means for engaging andmoving the leading ends of threads interposed between the ixed guides and the adjustable guide and means for elevating the adjustable guide, to cause the said threads to take a sinuous course. f

3. A drying machine comprising a pluyarn guides, an adjustable yarn guide, movable vertically from a position below to a position above the fixed guides, a rotary roll arranged to engage and move the leading ends of threads interposed between the fixed guides and the adjustable guide and means for elevating the adjustable guide to cause the said threads to take a sinuous course through the machine.

1. A drying machine comprising-a plurality of fixed thread guides, an adjustable thread guide, movable vertically from a position below to a position above the ixed guides, means for engaging and moving the leading ends of threads interposed between the fixed guides and the adjustable guide, means for elevating Ithe adjustable guide, said means including a plurality of Hexible cables each attached at one end to a lixed support, elevated pulleys engaged with said cables and supporting the same in bights or loops adapted to support the adjustable guide, and rotary pulleys to which the opposite ends of the cables are attached, said pulleys being adapted to wind up portions of the cables and thus elevate the adjustable guide. y.
