Application led February 28, 1910. Serial No.51i6l14...k

This invention relates broadly to vdyeingmachines and relates particularly to an improvement over the construction set forth in my Patent No. 955,993, issued April 26,1910, wherein a tank forming a chamber which receives the mass to be dyed is provided with a perforated false bottom and a perforated centrally disposed distributing member for distributing the dye liquor together with a cover for such tank provided with discharge openings adjacent the periphery thereof and adapted to cause an outward and` upward circulation of the dye liquor whereby the mass is expanded out laterally against the side of the tank and upwardly against the underside of the cover so that channeling around the mass and through the mass is prevented.

This invention relates to the same type'of machine except that the falsebottom is prefably in the shape of an annulus and is adjustable relative tothe central distributing member so'that diii'erent quantities of inaterial may be dyed in the machine eiectively and with ease, and to means for raising the bottom against the mass as it shrinks in size and during the operation of the machine. i Y' The invention also relates ,to a modication of this machine wherein the discharge' openings are arranged not only in the cover but also in the side of the tank adjacent to the periphery of the cover whereby the discharge 'is increased and yet the lower part of the tank below the discharge openings is left imperforated to allow for the shrinkage of the mass.

Further invention resides in thearrange- ,ment of a samplingdevice whichis freely accessible from the outside of the machine and which will receive a portion of the mass to be dyed so vthat the operator may detery mine at all times during operation just what is taking place within the machine.

Still Vfurther invention resides in certain v perspective view of the sample box; Fig. 6

is a detail of' one of the blocks and screws for forcing down the cover; and Fig. 7 is a detail of one of the clips in place ina portion of the upper ring of the tank.

In carrying ,out the invention any pre ferred form and construction of parts may be employed so long as they possess the necessary characteristics, but l khave shown herein one construction which produces very effective work, and in such embodiment 1 represents the base of the tankkwhich is provided with an annular groove '2 and vears 3 on the periphery of thef'base for receiving clamping boltsv to be described. Centrally the base 1 is provided with an openingfi to receive the inlet pipe 5 and with another opening 6 to receive anl outlet pipe 7. The base is also provided with an opening 8 for receiving a steamrpipe 9r which@ 'connected to a steam distributing pipe 10 the baise of the tank and extending on the ins1 e. f

The tank proper is composedof a bottom 11 preferably of wood and adapted to rest upon the upper surface or the ibase l and to engage an annular recom 12in the side 13 of the tank. The side wall ofthe tank is preferably made of wooden boards, and the ends of these boards extend beyond'the bottom 11 and into the recess 2. The boards forming.' the side wall are held in circular` arrangement or in cylindrical form b sun,- able metal straps 14. Ashoulder 15 is pro vided'on the interior at the upper edge loi the side wall and this forms an annular up- Ward projection 16 which engages in a recess 165V of the upper ring 17 of the tank.;

This ring 17 is preferably of cast metal 'and' is provided with ears 18 for receiving through bolts 19 which passthrough the ears 3 of the base and hold the upper ring and the` base together against the upper and lowe'r edges of the side wall. vThe uper ring 17 is provided at several points around the periphery with a slot 20 havingan upwardly extending recess 21 at one end and communicating with an internal recess 22 within the ring and at the back end of each slot 20. These slots and recesses form openings and securing shoulders for Athe clips and cover blocks and screws tobe described.

Resting upon the bottom of the tank and against the side wall and secured in place if desired are supporting vblocks 23 which are adapted to support, when in normal position, the false bottom 24 which is provided with perforations 25. This false bottom is in the form of an annulus having a large opening 26 at the center and recesses 27 at the inner periphery for a purpose to be described. This false bottom has securedv in it theends of a cable 28'which pass up through the cover and may be connected to a load hook A of a suitable hoist whereby the false bottom may be raised independ- -ently of other parts.

. provided with outwardly extending lugs 32 which are adapted to pass through the recesses in .the inner periphery of theals'e` bottom`24 and to engage upon the underside of the same and support vit in any position so that the machine may be varied in capacity by elevating the false bottom on anyof the lugs 32. The upper part of the distributing member extends inward with sloping sides to a central imperforate boss 33 and these sloping sides are provided with perforations 34 which are smaller thanthe perforations inthe side wall of the central distributing member. 4The boss-33 is pro- 'vidednwithan `opening- 35 which receives the threadedfshankfof a bolt 37 which is secured'in' jlace'in the distributing member bvv anut 38 upon the underside of the boss y33. Theupper end of the` boltisprovided withan eye 39 in which-may be secured the i hook of ahoist.

Resting upon the boss 33- isthe cover 40 which is preferably solid and 'has a central.

cylindrical portion 41 whichhas an opening therein slightly less in diameter than rthe diameter of the boss 33, but made suiciently large to admit of access by the hand to the edge of the boss so that in packing the tank -41 is finished to receive a nut 42 which is threaded onto the bolt 37 and is provided with peripheral openings 43 or a Spanner wrench. The cover 40 is still further provided near its periphery with a group of discharge openings 44 which permit the passage of the dye liquor from within the tank to a point above the c'over.' The nut 42 holds the cover down uponthe mass and the mass when it is rst packed,.holds the false bottom down upon the flange 31, and in order to hold all of these parts within the tank suitable blocks and screws and clips are provided. Each of the blocks comprises a body portion 45 having` a threaded opening 4G therein for receiving a bolt 47 which is adapted to engage the cover. The body portion 45 of the block is also provided with a flat p-rojection 48 which is adapted to extend through any one of the slots 20, and a lug 49 extending upwardly from the fiatv projection and for engaging that portion of the ring 17 iin front of the internal recess 22. The block may be locked in position by registering the lug 49 withthe recess 22, and the flat projection with the slot 20. The block is then pushed outward from the center, or in other words, the flat projection is pushed into the opening and the block ispthen given a slight movement eircumferentially with respect to the ring. so that the lug 49 engages in the segmental recess 22. The block is then secured to the ring and the bolt 47 may be screwed down to force the cover and the other parts into the tank. When they have been forced down properly the cover clips may be put in place in other openings in the inner periphery of the upper ring 17,*and the body portion 50 ofthese clips is similar in all respects to the body portion of the blocks, but in place of' the screw 47 there is a long shank which is adapted to extend down and engage the cover. The object of the clips and the blocks and'screws is that when the parts have been pressed down sufficiently vthe clips may 'be put in place and the screws removed so that the threads of the screws and the vthreads of the blocks are not impaired by the action of any acids which may be resent in the dye liquor. n he sidewall 13 ofthis. style Aof tank 1s provided with a .discharge opening 14 at a ,pointI above the point Awhich the cover 40 normally assumes, and in y this opening is secured adischarge pipe 51 which extends down and engages a three-way valve 52 which receives in one of its connections the pipe7 and receives in the third a pipe 53 connected to the inlet of a centrifugal pump 54. A connection 55 is provided in this inlet of the .pump 54 for a purpose to be later described.

lt will be seen from the above connections that by the operation of the valve v52 the liquor may lbe drawn from the bottom or thelupper part of the tank, the former operation being conducted through the pipe 7, and the latter through the pipe 51, it being obvious, of course, that when one is operating` the other is closed.

k he pipe 5 which is the inlet pipe to the bottom of the tank, leads to a three-way `valve 56 secured to the outlet pipe 57 of the pump 54. Another pipe 58 leads from the three-way valve 56 to a point above the toD p of the tank, so that instead of delivering the dye liquor from the pump to the bottom of the tank, by manipulation of the valve 56,

2O the liquor may be delivered to the top of the tank.

-The side wall 13 of the tank is provided preferably at a point opposite to the opening 14 with lanother opening 14, and lthis receives a pipe 59 provided with a valve 60 and suitablev elbow connections and 'discharge pipe 61, and this pipe '61 is adapted to deliver the liquor from above the cover ,to av heating tank 62 which is* provided at its bottom with a steam inlet pipe 63 and with a discharge pipe 64, which is connected to a valve-65. This valve 65 is connected `by a short pipe 66 with the connection 55 at the inlet ofthe pump. K.

In operatin the machine, normally the mass isplace within the chamber' formed by thevside wall of the tank, .so that it -is arranged around the central distributing member. When the proper amount of material has been placed within the tank the cover is' put on and is .forced down,and by means of thegnut 42 the lower edge of the cylindrical portion 41 is brought down so that it engages the boss 33. llf any material should rest upon the boss it may be removed by the hand through 'the opening Within the cylindrical portion 41 before the nut 42 is brought down in place. The parts are then held within the tank by means of the bloc-ks and screws and -finally by the clips before referred to, and

dye liquor is supplied to the machine from.- the tank 62 where it is being heated by steam from the steam pipe 63, the liquor being drawn from this tankV through the center of the pump 54 and being then pumped up 4through the machine through' ma filled, by shifting the bottom so that the the pipe 5. The dye liquor may be permitted to pass out through the 4pipe 59 and through the course just described .to the pump, the valve 52 being closedfor both connections 57 and. 51, but when itis desired to cut of the circulation through the tank 62 the valves 60 and 65 are closed and 85 Hthe lvalve 52 is set'so that the pump is drawabove the false bottom and ing the liquor through the pipe 51 from the top of the machine and delivering it through liquor may be drawn from lthe bottom of the machine and delivered through the pipeA 58 above the cover. In fact 'many times it happens that better results are produced by first directing the dye liquor upwardly from the bottom through the mass and then reversing the direction of the dye liquor by delivering it above the cover by the pipe 58 and sucking it through the mass to the pump. Any desiredcirculation of the dye liquor through the tank or to the heating tank 62 may be brought about.

In the modification of the invention shown in Fig. 3, the side wall 67 is provided with an annular group of perforations 68 which extend above and below the periphery of thev cover when Vit is in normal position and the outsidezof the tank is provided with an annular casing 69 which is secured to the side of the tank. This annular casing has a suitable vconnection for the discharge pipe 51. In this embodiment the discharge openings are at the juncture of the cover and the sidewall and are below and above the periphery of the cover.

In order that the operator may know the condition of the materialwithin the tank a test box is provided for use in conjunction with the discharge of the tank, and this test box comprises a heavy base 70 which is in the form of a frame having an opening 71 therein and "a framework 72 which receives on all sides wire net 73. Av cover 74 is hinged to 4this framework and -is provided with a suitable latch 75 which engages a' pin 76. This boX is either secured or set upon the cover adjacent to the discharge opening for the pipe 51 so that the dye liquor from the tank is drawn up through the opening 71 in the base of the box, through the wire net which is on all sides and through the sample of the material which is placed within Athe box, so that by reason of the looseness of this sample and by reason of its small size the dye is distributed through it and it is in the same condition which prevails in the material within thetank so that the operator by observing this sample may know exactly vwhat is taking place within the machine.

If it should be desirable at any time to reducefthe vcapacity of the machine,`this y be accomplished, before the tank 1s recesses at the inner periphery are in vertical alinement withrthe lugs 0n the exterior of'thecentral distributing member when the false bottom. may be raised or ylowered past aol any of the lugs and then rotated so that when' it is released again it will rest o n other lugs whereby when the machine 1s packed, it will receive less or more material as the case may be. The object of raising the false bottom to decrease the capacity of the machine is that no matter what the amount of the mass to be dyed may be, it will be held up against the underside of the cover upon the initial starting of the machine, for it is Aquite obvious that if there were a small mass of material in the bottom of the chamber, the ldye liquor could iiow v over the mass from the center to the periphery and satisfy the force of the circulation, thereby forming a channel, and if this chan-v nel is formed there is nothing to circulate the dye liquor through the mass. v

By the arrangement of the cable connections with the false bottom the latter may be moved upward against the material as it shrinks during the dyeing operation, and

if desirable the lugs about the central distributing member may be eliminated and the change in the capacity ofthe machine may be brought about by varying the position of the false bottom prior to the dyeing 0peration or after the material has become moistened with the liquor, as the false bot-A capacity and any quantity of material may v be dyed in it.
