To all whom it may concern: Y

Be it known that I, ARTHUR Nonnisori MARR, residing. at. Rangiora, Thorner, near' Leeds, in the county of York, Eng- Y Sland, have invented new and useful Imrovements in Apparatus for Dryin Sized 'arns and Warps, of which the 0 lowing.

' is a' specification.

This invention relates to improvements 19 in machines or apparatus for drying sized cotton, or worsted, or woolen or other yarns andwarps, and it is particularly applicable to that class of machines known as cylinder sizing machines provided with posi- -tive drivin mechanism and having a creel and sizing. ox on one side of the cylinders, and onthe other side a headstock with cooling fan, or fans, conductin rollers, polishing dividing rods, and revo ving yarn-beam 20 'presser.

' The object of this invention is to dispense with the above named cylinders,which are heated to the required temperature, and.

over and partially around which thensized 2 wet yarns or warps are made to proceed or pass in their passage from the creel and sizing box to the yarn be'am,and to substitute therefor an air drying chamber rot-a vertical ty e provided with anumber of pard rollers, heating apparatus. and fan or fansfor drawing and circulating the heated air simultaneously through the sev--- 'cllilamber D is preferably open to the atmosp ere.

from which the war or sheet is led. to,. the chamber of'the rying mac 'ine. All the above parts are of the usual and r ordinary type and willbe readilyunderstood by those engaged inthetrade. with out further description.

Between the 'sizingbox and headstock portions of a sizing machine is inserted the vertical air drying chamber of any suitable size and shape in cross section, suchas rectangular as disclosed in the accompanying drawings. The vertical air drying'cham ber takes the place of one, two, or more revolving drying cylinders which are usually employed in this class of machine. The vertical air drying chamber is wholly or 7 partially formed of wood, or irompra combination of twoor more of. summaterials "and it is horizontally divided into two chambers or compartments G, D, of unequal size and area. -The upper and larger compartment 0 is employed for drying purposes and the smaller one D which islocated m the base of the structure s for the reception of a portion of the heating apparatus, and one or more fans which are employed for causing the air first to; enter the drying chamber C,- and then to circulate through the several verit is-divided, and to withdraw the air and v moisture therefrom: into the fan; the lower A convement way for forming the drying chamber isto makea framework offour 1 uprights h, preferably-of channel-beam construction, with ends and sides in sectionsand arranged between a number of spacedand suitably formed horizontal cross pieces or beams 72 fixed by their ends to the uprights The sections are made in panel form, fo'rconvenience of transit and erection, and placed in position between each 1 I pair of cross beams 71, being strengthened by 1 0 suitably constructed cross stays j which form part of each section. By employing a number of horizontal. cross pieces or beams I the frame work in the first case is built up in skeleton form, and divided horizontally N into the two chambers C D. The inner walls of the structure'are lined with wood,

orother suitable materialnot bein afiected to any appreciable extent climatic or he lower por 119 tion of one or more sides of the drying chamber is made in panel form Z and provided with access doors m fitted with glass.

The upper chamber C is divided by partitions it and into any required number of vertical compartments, or sections, for example, first into four vertical compartments p by the partitions 0, and afterward each vertical compartment p is again sub-divided by the partitions n. The vertical partitions n which come against the heating or radiating pipes 00 and y are formed of strips'of sheet iron, as shown at Fig. 4, and they are made secure to the pipes of the heaters a: and

3 and are retained in position by the bolts 2 arranged to pass through the cross bearers 1 which are formed of iron. The cross bearers 1 also aid in retaining the radiator pipes of the heaters w and y in a level position. The portions of the partitions n above the top of the radiator pi es a: and 3/ are either formed of wood, or 0 sheet iron,

The chamber C is closed at its top with a cover 9 preferably having a number of 'openings therein, one foreach compartment 1) and being closed by doors r. In the top of each compartment '77 is mounted insultable ball or other bearings a roller 8, andat the bottom of each partition 0 is a roller 25 extending partly into each of the adjacent compartments. The first tworollers s and t over which the Warp or sheet passes are preferably lagged and provided with driving elements u, 'v, disclosed in the form of sprockets. The remaining rollers preferably are not lagged. The rollers't'are ar-- ranged at a suitable distance above the bottom of the vertical chamber C.

The warp or sheet of yarn to be dried as :itleaves the rollers e and f of the sizing box is carried upward and downward and tend fromthe bottom 2 of the drying chamher 0 to the underside of the rollers 8 while through the compartments over the rollers s, t in the sinuous manner as shown at Fig.

1 of the drawings. The rollers s are arran ed at a suitabledistance below Q18 top Q o the chamber C. The partitions n exthe partitions, oextend from the top 9 of the chamber C down to, and near the top,

of the rollers t. By this means and by closing the vertical chamber C on its bottom, except providing openings 3 and 4 therein respectively for the entrance of the warp orsheet gr and the heated air for drying purposes,

provision is made for leading the war or s eet'giup and down between the jwho e or any number or the compartments so asto besubjected' to the action of the heated air- Which is driven into the chamber.

by thefan- 5." The partitions are arranged rollers and are provided-for each layer of to beabout the center of their respective yarn, or warp, or sheet being isolated for drying purposes.

ipeaora On the partitions m. and 0, and also on one or more of the inner sides of the vertical chamber C, are fixed horizontally at suitable distances apart a number of triangular shaped blocks 6 for contracting the size of thecompartment, and also for directing the air currents on to and through the wet warp or sheet 9, thereby causin them to slightly vibrate andseparating t em from one another, and also preventing the individual threads forming the warp or sheet adhering to each other. The blocks 6. are made the full width of the partition in each compartment. At Fig. 1 it will be seen that on the entrance side of the vertical chamber three of such horizontally angular shaped blocks are fixed to its inner side, and at the first division 97, only one of such angular shaped blocks 6 are used, and in other instances it will be noted thatsuch angular blocks '6 are placed on both sides of the partitions. The number and position of the angular shaped blocks may be varied as cir- '3 cumstances', and the number of the warp or sheet 9, requires. In some cases it'may be found necessary 'to-employ more of these horizontally fixed angle blocks 6 than in other cases, therefore it must be distinctly understood that they ma be varied as required. The sides of .t e blocks are-reguired to be at such an angle that they will irect an upward or downward current of warm air against and through the warp or sheet g.

j The heaters :22 and y are radiators of the,

ordinary type formedof a number of pipes of varying lengths arranged-in rows, .and-

extend the full width oft-he warp or sheetg. v v The pipes in one 'rowof the radiators m,-which are laced in the chamber D,- pass through t e opening 4 and extend asuitable distance within the vertical chamher for drying the warp or sheet 9 as .it

passes up to the first r0 r .9 and down to the first roller Z. If desired two. or more radiators a: may be used in chamber D for obtaining a variation of temperature; An additional radiator y is provided for occa sional use in very cold or very wet weather,"' 4

and for circumstances when extra heat is required for drying urposes. The heaters or radiators w and y eing of ordinary construction will be readily understood without further explanation.

5 is "a fan of any ordinary construction "placed" in the chamber D, and it may be rovided with one or more suction inlets. n the. drawings the outline of a fan of the Sirocco type is shown provided with two suction inlets 7 and 8.

9 is the fan shaft upon which the driving I pulleyor motor 10 ismounted.

To each suction inlet '7 and 8 is provided a funnel shaped opening or air trunk 11, 11, as shown by the dotted lines yawn circulate through the compartments of the said chamber and to be drawn out therefrom throu hsuitableopenings or apertures. The

- air, a er passing through the fan or fans 5 is discharged through the outlet 13 on to the heater or radiator a and passes through opening 4 into the drying chamber.

In practice ithas been found that none of.,- the rollers s and t need be driven from the elements u, "v as the frictional con drivi tact b the warp or sheet passing over roller is found to be suflicient.

Around the top of the drying chamber C may be fixed the supports 14 to which thelatform 15 is fixed, and around the platibrm may be fixed the'rail 16 carried by the pillars 17. This platform provides a ready means for getting to the top rollers for lubricating "and adjusting purposes, and-' also for openin or closin the doors 1'. The bya ladder n ot platform may e reache shownin the drawings.

The action of the apparatus is as follows :The warp or sheet 9 as it leaves sizing box p'ortion'.of a sizing machine is passed through the opening 3 which extends the full width of the chamber C and it is then carried up and passed over the first roller 8 downto the first roller t and is led' in -a:sinuous manner up and down, and over and under the rollers until it reaches the bottom conducting roller 18 and from thence it is drawn and divided1through the headstock and wound on to the loom beam. As the warp or'sheet g is drawn through the vertical compartmentsthe'air that has been drawn into the-fans is passed through the air trunk 13 and after passingamong the tubes-or coils of the heater .7: it enters the drying chamber C through the opening 4 and passes up the first chamber or compartment and in so doing comes in contact with e blocks 6. In the ascent of the air. through one compartment it will strike I against the undersurface of the blocks, and

f-J'as it passes down on the opposite side, say, of partition's n and o it will come in contact with the upper sides of another set of blocks and as it comes in contact with each angularface of'the blocks 6, the air will be directed against and through the traveling sheet I thereby causing the latter to slightly vibrate for separating the threads of am. so

The

.fan by being connected at 12 with the last vertical compartment of chamber C will draw the air through the whole of the comartments, and back into chamber D and an 5, thereby more quickly and evenly drying the yarn. By isolating each layer of lber C and .iof the cylinder siz1n "yarn or war in the compartments as described permits of the warm air following the same sinuous path as the war or sheet g at the same or at a difl'erent sur ace speed, and also allows the maximum time for contact between the warm drying air and the wet warps, and further, in the event of broken ends, such ends ane'carried along with the air current. By opening the doors 1 at the top of one or more ofthe compa'rtments, moist air is allowed to-escape, or cold. air may be drawn into such compartments when and as desired. 1 a The above described vertical drying chamrts connected therewlth are arranged to orm part of, and supersede the cylinders of a sizing machine, and the parts machine not herein particularly mentione or described may "be of the usual and ordinary construction.
