To all whom t 'may concern.'

Be it known that l, lVAL'rnn A. Nivmivc, a citizen of the United States, Iesiding at Boston, in the county oi' Sulioll and State of ltiassaciiusetts, have invented a new and useful Apparatus for Sizing Yarns, or"

which the following is a specificatioi/i By Way of explanation it may be stated1 that in the manufactureof cotton cloth, a sizing of. the thread or yarn is necessary, in order to lay the fibers and to strengthen the yarn suiiiciently to better lit it for the Weav-I 'ing operation. lt is the usual practice to draw or run into the size box, a quantity of the sizing material sufficient to bring about the desired depth and .to secure a maximum sizing 'eiiiciencyg` and to restore this depth by an addition of sizing material, when it is noted that there is not sufficient material present in the size box to size the yarn properly. .As a resultzof the foregoing operation, a maximum depth of sizing material and the conditions which promote a maxiy mum efficiency, prevail for an instant only,

and at times, Work ivliolly unsuited for the cperation oi Weaving, results, due to the failure to restore a proper depth of the sizing material soon enough, and, due to .the fact. thatkthe depth of the sizing 4material is constantly changing, and may fall too low. The amount of sizing material taken up .by the yarn depends on several factors among which may be named, the density of the solution, or mixture, the character of the material used 'for the sizing, the tension, the twist, the size ot the yarn, and the depth of the submergence, as Well as the time the yarn is kept submerged, either from the rate of travel or the depth of the sizing material or both. A varying depth of material there- -iiore aiifects the length of time during which renc-.ned and uniform size.

tbeyarnis able to absorb the sizing material.

`@ne object of the present invention is to. provide novel means for maintaining the u .size at a constant level in the size box.

Another ,object of the invention is tov provide novel means whereby the supply of size` ismade to flow continuously through the size box, which feature gives a constantly inet-lier: object of the invention is 'te pro' viele novel means .ier `disposing or the ob actionable matter in the size, also caring I Speeicationof Letters Patent.

much size which would otlie .vvisey Suder deterioration and be lost, nota f y4 attore prolonged stoppage of the sizing `op at1on..

Another object of the-inventif) is toprovide novel means for returnin the contents o the 'size box to a storage tan ,and for directingtbe contents of the ,size box into a sewer, at will.

Another object of the invention is the saving of that portion of the 'size remaining in the size box at the noon stopping hour, at the end of the day, or at the completion of a set, by returning the same promptly to the storage kettleLbefore it can deteriorate'- in quality, congeal7 or form in soluble lumps It is Within the scope of the invention to improve generally and to enhance the utility of, devices of thattype to which the present invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides inthe combination and `arrangement of parts and inthe details of construction hereinafter described and claimed, it being understood that changes inthe precise embodiment of in `vention lie/gein disclosed can be-made Within the scope/fof Whatis claimed Without departing fromY the spirit oflthe invention.

varied as the judgment of the operator may demand. Any suitable mechanism indicated at 8 may be provided for actuating the beater 7 when the beater is used.

The kettle 2 is equipped With an outlet 9 carrying a cut ofi' valve 10. The outlet 9 from the kettle 2 discharges upon a screen 11 held in the mouth of a storage tank 12.

Should itibe `desired to heat the-contents of the storage tank 12, the same may be j acketed or insulated as at 14, although any other suitable means known in the art, such as a coilv 141, for heating the storage tank may be resorted to.

A return pipe 15 extends beneath all of the size boxes l, the return pipe 15 opening into the storage tank 12 above the screen- 11. A pump 16 is interposed in the pipe 15. The pipe 15 is provided-With a branch 17 for each size box 1, the branch 17 entering a4 depression 18 'formed in the bottom of the size box, the depression 18 being of suiiicient size to collect the lumpy portions of the size.

Thrust into the upper end of the branch 17 and located Within the size box 1 is 'a vtubular stopper 19 which, at its upper end,

may terminate in a funnel 20.` The upper end of the funnel 2O is spaced from the bottom of the size box 1, and thus, a constant level is maintained in the size box. The numeral21 indicates a sewer, the same having a branch 22 for each size box 1, and each branch 22 is connected to the branoh`17 of the return pipe 15 below the` bottom of thev size' box 1. A cut oti valve 23 is located in the branch 22 of the sewer 21 and a out off valve 24- is located in the branch 17 of the return pipe 15.

Journaled for rotation adjacent one side of the size box 1 is a guide roller 25 near which is located a vertically adjustable im- 'mersion roller 26. Adjacent to the immerneath the immersion roller 26 and between the coacting rollers 28 and 27. Obviously, by adjusting the immerison roller 26 verrlhe box 1 may bev jack# are open, and-that the valves 33, located in the -branches 32 of a delivery pipe 3 1 are open, the pipe 31 entering the storage tank 12 and the branches 32 of the pipe 31 discharging into the size boxes 1. Under such circumstances, the operation of the structure is as follows :f-.The size contained in the storage tank 12 will pass by ivvayf ofthe pipeK 31 into the branch 32 and `ithen Acinto. l

the size box 1, iilling the size box to level determined by the upper end of the stopper 19. Then, the material 30, passing around and between the several rollers, 25.I 26, 27 and .28 Willbe immersed to a xedextent, a ixed level of the size in the size box being maintained,'because the size is continuously supplied through thepipe 31 and the branch 32. The insoluble or undesirable matter in the size Will accumulate on the bottom of the box 1 andthe excess' portions of. the size will flow .through the stopper 19 and pass by Way ofthe branch-17 into the pipe 15, the pump 16 forcing the size upon the screen 11, and

- the size passing thence into the tank 1'2, to

repeat the cycle. l i l Suppose that it is desired to return all of the size in the size boxl lto the tank 12.

all of the size, will pass into the branch 17 and by Way of the pipe 15 onto the screen 11 and into the "tank 12.

When it is desired to discharge all of the size intothe sewer 21, the valves 24 are closed and the valves 23 are opened. Thereupon, .when the stopper 19 is lifted all of the size will flow into the branch 22 and thence into the seive'srv 21', and'thebox may be cleansed thoroughly by Washing.

A fresh supply of size may be run into the tank 12 at any time, from the kettle 2 by openingL thevalveL 10. lThe consistency of the size may thus be regulated. l

In Fig. 3,y a slight modification in the means for maintaining the level of the size constant is shown. This device, it is to be understood, may be used in connection with the return mechanism and delivery mechanism and with the heating and storing structurc shown in Fig. 1, the only modification being inthe size box connections.'

lnrFi'g. the size box is denoted at 34, anda nipple 40 enters one end of the size box 34 in agroove or 'depression vin the bottornof the size box. The outer end of the nipple 40 enters one branch 38 of an inyfverted, U-shaped pipe 35 vv'hichislocated outside pf the lsize box.l ,This pipe has a vent valve 35 whereby the pipe 35 is prevented from acting as a siphon. In the branch 38 below the nipple 40 there is a cut 0E valve' 42. The branch 38 at its lower end discharges into the sewer 44. The other branch 37 of the pipe 35 discharges intol the return pipe 43. Communicating. with the gbranch 38 is an angular pipe 39 discharging 'inw the return pipe 43. In the pipe 39 thereisalcut oil' valve 41.

Vhen the valves 41 and 42 are closed, the size will pass'l throughthe nipple 40 and then traverse the branches 38 and 37, the size passinginto the return pipe 43. The size 13T' Ywill be .kept at a'constant level, determined "bv the 'distance of the top of the pipe 35' from'the bottom of the size box.v By closing the valve 41 and by opening thevalve 42, all 'of the size may be run into the sewer 44. By closing the` valve 42 and by opening the valve 41, all of the size may be run into the The .formshown in Fig. 3 is preferable when ,the invention is applied to a plant A already installed, since by the use of'the l v structure above referred to, a minimum numloer of changes need be made.

. Especial prominence is given those forms of the invention rwhich i appear in Figs. 3, 4 and 8. When these: forms of the linvention lare employed, not only is the lsur- 1 plus size `removed, but the objectionable matter which isusuallv in the form of heavier particles,- is removed' from the bottom of the obviouslwr size box,l the heavier particles r bottom of `tending tov gravitatey toward th thesiz'e box.

Referring'` particularly to Figs. 4, 5, and

6,/th sizebox is denoted by the numeral' andthe tubular stopper by the numeral 101.' The stopper-- 101 is` provided in its Y side and adjacent thelipttompofthe. size d,100'with 'an 'opening102l Located within thejstopper'lOl isa transverse partition 103,

extended ventirely across theI stopper, the,

. lower end of the partition 103 being `prolonged as indicatedat 104 into union with` the stopper 101 below `the openingf102. A. `fplate 105 is secured to thebottom of the size box, the plate 105 being provided with .an upstanding, curved ,flange i106 which its a', clsely around the stopper'101.

' When, the parts are positioned as shown in Fig;A 4, 'the surplus' size l in the box 100 will pass into the stopper -101 through the opening102, and Arising, pass over the upl y' per edge-,of the Jpartition 103, the sizepass'- e ing then downwardly .out of the stopper.

By rotating the stopper 101 through fa; of approximately 180, the opening come oppositely to lthe flange 106` an closed thereby. Under such circumstances the surplus size will overliow into the 'i of the stopper 101' and will pass down." wardly therethrough. i

Referring to Figs. 7 and 8, the sizebox is denoted by the numeral 107. A pipe 108e ters one vend of the size box, the inner vend oli the pipe 108 lying in a groove ofthe botl tom of the size box. The pipe 108' corri municateswith an upright pipe 109 containcates withasewer- 112. Branched off from ing a casing provided withv a threeway valve 116. The ends of a loop VshapedfpipeA -f A i 117 enter opposite. ends of the casing 115. The pipe 117 is provided at itsorown with ing a c ut off valve 110, the pipe 109 dis-"' charging into a pipe 111 which communia' vent valve 118. An extension pipe 119 enters thelowermost portion of theloopshaped pipe117, the pipe 119 communicating with a return pipe 120. Interposed in the pipe 119 is av easing 121 provided with a three way valve 122. Entering one side ofthe casing 121' is a depending pipe 123 communicating with a return pipe 124.'A

1n that form of the invention which is shown in Fig. 3, the pipes may become',`p

stopped up and that'form of the invention' which is shown in Figs. 7 and 8 vwill permit a stopped up pipe to be blownout readily by means of a steam'connection united witheither of the return pipes or 124.

When the three way valve 116v is manipulated to close the pipe 114 and when the Vvalve 110 is open, the size in the box 107 will pass by way of the pipe 108, the pipe 109 and the pipe 111 into the sewer 112.

When the three way valves 116-'122'are disposed as shown in Fig. 7, the valve 110 being closed, the size may be Adrawn ofi thebottom of the box and will pass into the- ,pipe119 and by way of the pipe 119 into. the return pipe 120. However, by-manipulating the three way valve 122, the size may be directed by way of the pipe 123 into the return pipe 124. The size, at the will of the operator, may therefore be returned, either' tothe heavyA size kettleby Way of pipe 120 or to the light size kettle by way of pipe 124.@

By properly vmanipulating the three way lma valve 116,. the size will pass through the pipes 108 and 1,141,130 the 1o p shaped pipe 117, a 1mi beis'g thus maintained in' the size box, the size passing from the .loopshaped pipe 11'? linto the pipe 119 and from the pipe 119 to the return pipe 120 or iltp the pipe 123 and into the return pipe 124,

depending'- upon the position of the three Wav valve 121.l It will be understood readily that by propfinaaeaa erly manipulating the several valves shown, a stopped up pipe located anywhere in the system, may be blown out by means of a steam connection opening into the pipe l2@ volume; and means for guiding through the size boX the material to be sized.
