( c1. es '9 The present invention relates to machinesfor dyeing lengths of continuously moving fabric webs, and in such -manner that theweb is passed through primary and secondary dye baths with intermediate roll pressure means and thence into a development chamber within which heat is provided, as by steam coils. In thischamber the fabric web "is led over the-lowermost of a series of separator rolls and thence passes over one or plurality of rolls carrying longitudinally extended slats, the Web then being led to the upper area of a chain-feed, consisting of two or more spaced chains carrying between them spaced slats or bars upon which the web rests in its movement from one end of, thechain to the opposite end. After leaving the chain-feed theweb is carried downward and ledover the second 'one of the separator rollers and thence'up, as before, to and over the chain-feed and thence down to thethird one of thespacingrollers the web moving in the same way-toeach one of the. spacing rollers until the layers of the fabric web on the chain are equal tothe number of spacing rollers employed, and the initial end of the web. lies at the inside or lower face of the pile atthe discharge end of the feed-chain. At this point the web is led over a turning bar and out of the casing in which the aforesaid elements are contained. By means of'such instrumentalities in thecombination, the fabric web -is dyed with uniformity throughout, and the-dye development maybe adjusted as to timewithout affecting thespeed of the machine, by simply changing the number of the separator rollers and hence the numberof laps built up uponthe feed-chain prior to the turning and discharge movement of the fabric webfrom the ,machine. it 1 The invention will be described in detail, with. reference to the accompanying drawings, in

, 2 the chains of the chain-feedshowing a plurality of laps of fabric web on two bars of the chain; Referring to the drawings, I have shown schematicallyin Figure l a base member I which carries a frame 2. The frame will consist of spaced sides supporting between them a primary dye cha'mber indicated atfi, and at the lower area of the chamber-will be disposed a guide roller lior 'the fabric web 5 extending down-- wardly from a guide roller 6. Between the ver tical frame members is a second guide roller 1, over which the wet Web ofiabric is led in its passage between squeeze rollers 8, Bar, the latter acting to press the dye into the fibers of the web andalso to remove excess dye. One of the rollers maybe pressed toward the other by the fluid pressure means indicated at 9 andwhich customarily will consist of a cylinder with a pistontherein thepiston being enacted to a rod l0 engaging one or both of the shaft supporting arms I l for the roller 8.

After leaving the squeeze rolls the 'fabricweb passes over guiding roll I 2 and downwardly under a dancer roll I3 within secondary dye tank M and thence upwardly into the dye developing chamber. Within chamber I l and at each side thereof, may-be disposed vertical guide channels l5 for the outwardly projected shaft ends of the dancer roll.

The development chamber may be of anydesired form and construction and is closed except for inlet and outlet passage ways for the travelling web. In Figure l the casing of the chainber-is shown in vertical section as constructed of 1 detachable elements and the chamber is generally indicated at l6. Inasmuch as the charm ber except for one or more face plates may be of unitary construction the section lines through the detachable units thereof are, for convenience Of-illllSlllflfllOll, extended in the same direction.

.The entrance aperture for the development chamber casing isindicated at IT and above it isa guide roll is over which the webfis led to thespaced slats of a feed roll 19. r This roll'i'nay be ofany suitable construction, including that illustrated inFigure 5. .The construction in that figure consists of-a shaft Ear carrying spaced disks il9,-whi ch in turn carry spaced slats; l filr'x. In the" drawing, Figure 1, four of the sa'id'feefi -rolls l9 are employed and each may have the same construction. l

As thehfabric :web -completes a downward movement from the initial feed roll IS, the latter being: positively driven it passes overthe lowermost end initial-separator roll Zil, from which theweb passes to the second feed "roll ill, and

thence toa third ,Ieed uroll.fl'9,. .fro'mavhich the web isjled itos the: barsv of the chain; drive.

The ichainldriyemay. consist of two chains or the equiyalentflexible lengths (one of the chain's being shown in Fig. 1, at 2|). Transversely extending bars 22 are carried by the chains, and the chains and bars, with their driving elements constitute the chain drive. These driving elements are the shafts 23 and two sprockets on the shafts lBa: may be journaled in bearing members (not shown) carried by the face walls 163: and 16mm of the casing l6 for the developing chamber, and these shafts may carry sprocket wheels 25 engaged by drive chain 26 which may run over either sprocket wheels 21 (Fig. 2) One of the said shafts may be positively driven, by any suitable means for effecting rotation of the shafts its and 23 to effect the drive.

In Fig. 1 I have shown means for heating the interior of the developing chamber i. e. the steam manifolds 27 and steam pipes 28.

The web of fabric after being led under each of the separator rolls 20 to thereby build up laps of fabric upon the chain drive equivalent to the number of separator rolls 20, shown in the drawing, passes to suitable guide rollers 29 (Fig. 3) and under a smoothing plate 30, if desired. And the endless belt 3! may serve as a support for the web as it advances toward the turning bar 3| (Fig. 3). This belt may be led over the pulleylike members 320i two drive shafts 33 carrying driving pulleys connected by belt 34 and short belt 35 with a primary drive shaft 36. Additional shafts 33 with belts supporting wheels (not shown) may be provided. It will be understood that the means for feeding the web to the turning bar, and for carrying the web from the turning bar to a point exterior to the developing chamber may be widely varied from the means illustrated in Figure 3, the latter figure being largely schematic and suggestive of suitable instrumentalities. Thus synchronized motors 31 may be employed for the entire drive system. These motors carrying pulleys 38 con nected by belts or chains 39 with pulleys on the rearward I of the shaft 33 which shaft may project laterally of one of the frame members 40 for the carrying of a pulley 4! which receives chain 34 and the carrying of a second pulley receiving chain 35 led to shaft 36. may be connected by bevel gears 42 with the shaft 43 from which power is taken for the operation of the chain feed and feeds for the shafts From the development chamber the web will pass through an opening indicated at 44 (Fig. 1) and onto a series of delivery rollers 45. The formation of the base area of the developing chamber, it being V-shaped enables economy in the quantity of treating solution employed in the chamber, and it will be seen that the fabric web passes through the treating solution as a layer entirely independent of other layers as to contact therewith, the number of immersions of each portion of the web being equivalent to the number of separator rol s employed.

It willbe understood that the time of travel of the fabric web through the development chamber while controlled by the number of separator members 20, may also be regulated by the driving speed of the machine and usual controls will be applied for that purpose. It will also be understood that the chain-feed at the upper areaof the development chamber may be independently driven as by means of a sprocket and chain Shaft 36 arrangement which does not include the slatted rolls on shafts [9:0. In fact these slatted rolls may be idlers if desired.

I have shown in the drawings a usual type of turning bar with a rounded edge for immediate contact with the fabric web. Any suitable form of turning instrumentality may be employed as for example a round rod or roll. When the slatted rolls l9 are positively driven the drive will, of course, be synchronized with the chain-feed. Also, it will be understood that the belt 3| at the fabric web turning device may be eliminated if desired, inasmuch as there will be sufficient tension upon the fabric web as it is drawn out of the development chamber to coact with the turning bar 3| for maintaining the fabric web in straight lines.
