Leading from the main steam pipe 25 is a steam pipe 5D having a manually controlled valve 5I` therein which leads down to the Ybottom of aback and forth steam coil 52 which runs back and vforth on the inside surface of the end'wall Il 'and has its upper end joined to a side steam coil 53 which runs back and forthv along the side wall I Sgand is joined by a pipe 5ft which leads from the lower end of this side coil 53 across toy the lower leg of a similar back and forth coil 53", being. connected with the lower branch of said coil which extendsback and forth in the same manner as the side coil 53 and its top leg is led through the back end wall II as at 55 into a suitable trap 56 and a return pipe 5l leads back to the. source of steam.

In the bottom of the compartment is adapted to .be disposed Water of a'suitable depth and in"r this water' is immersed suitable steam coils. This bottommember I2 has secured thereto in transverse relation apartition 59, having an opening 6!! therethrough, which is not only secured to the bottom I2 but has its ends also secured to the side walls I3 and Il! for reinforcement purposes.

' Leading downward from main steam pipe 25 is apipe 63' having a manually controlled valve 65 therein and which pipe 63 extends downwardlyv to nearv the bottom .of the compartment and penetrates the side wall I3 ina water-tight manner and is connected to one end of a back and forth coil` E5 which extends in a back and forth manner between the partition 59 and the end wall Il). y

At the other side of the compartment from the entrance point a pipe BS leads all the way along the side wall I4 and is connected to a back andv forth coil 61 disposed in the rear end of .y thev compartment adjacent to the floor l2 thereof.

I'l-hje other end ofthe coil is connected by a pipe 68 to a. suitable trap, not shown but similar to trap ,and is led back to the source of steam.

The-compartmenthas suitable openings 'l and chamber comprises-,front andfvrear end ,walls Ill doVA 'IfI' closed by suitable-doors, these openings being 3 located in eithei` of the side walls i3 or 4 but preferably in side wall i3 as shown in Figure 2.

The end wall I has a suitable ventpipe 13 therein with a suitable valve or vane 14 pivoted therein which can be regulated as to position to prevent pressure from being built up in the compartment on account of the great amount of steam within the compartment. trance of outside air but allows the excess pressure created within the compartment 9 to .be vented through this pipe 13.

Leading from the main steam-pipe 25 is a pipe 15, having a manually controlled valve 16 therein, which leads down and is connected to a horizontal and transverse pipe 11. Pipe 11 is connected at each end to vertically disposed pipes 18 and 19 whichrhave connected thereto transverse perforated pipes 80, 8|, 82, and 83 which lead through the side walls I3 and I4. Pipes 80 and 82 are perforated on the rear side or remote from the observer, as viewed in Figure 6, and pipes 8| and 83 are perforated on the nearside towards the front of the machine.

Leading from the main steam pipe 25 is a plu' rallty of pipes 84 having manually controlled valves 85 therein. The pipes 84'lead down and are connected to transverse pipes 86 and vertically disposed ,pipes 81 connect to each end thereof. Disposed between each pair of pipes 81 is a plurality .of

perforated pipes

93, 94, 95, 96, 91, and 98, which lead through the side walls of the machine, these pipes being connected to the lower` end of pipes 31. The

pipes

93, 95 and 91 are perforated on the rear side and pipes 94, 96 and 98 are perforated on the front sides.

Forl furnishing hot waterv at substantially 210 F. to certain spray pipes to be presently described, there. is provided an instant steam hot water heater |00, known as the Johnson hot water heater, which is of conventional structure and has a plurality of steam 'coils therein around which water passes to quickly heat the same. The ordinary cold water from a suitable tank or city pressure enters this hot water heater through a pipe.|0|. A pipe |02 is connected to main steam pipe 25 and has a manually operated valve |03 therein, this pipe |02 leading into the water heater |00 and being connected to the coils, not shown, and the. steam passes through trap |04 to a return pipe |04' which leads back to the source of steam. i i Y The water, after being heated, emerges from the water heater |00 through a pipe |05 and intol a suitable electrically driven pump |06 and emerges from this pump through apipe 011 which has a manually controlled valve |08 therein, the pipe |01 also having a suitable check valve |09 therein. The pipe |01 leads upwardly and lat- Y erally and is connected to a transverse pipe ||0 has downwardly extending legs and w ample, to Overflow Into the Wash bOX formed by ||2 to which are joined transverse'pipes ||3, ||4, |'|5, and H6. The pipes ||3 and |I5 are perforated on their rear sides and the pipes ||4 and I6 are perforated on their front sides and through which perforations thehot water will pass at a pressure of substantially 100 pounds to be forced through the cloth.

The apparatus has associated therewith an impregnating box |20 having a drain valve |2| and disposed above the box |20 is a plurality of lower squeeze rolls |22 and upper squeeze rolls |23 and within the box, immersion rolls ||9.

Joined to the rear wall of box |20 is a seal trough |24 which has a suitable drain valve |25 in the bottom thereof.

4 Y is disposed in an opening in the front side wall l0 and completely closes the same and extending downwardly from the front side wall I0 is a vane |26 which projects downwardly into the trough so that the liquid sealing medium |21 will cause It prevents the en- Vthe lower portion of the vane |26 to be submerged. There isan immersion roller |28 mounted in the-seal trough |24.

j, Acaustic-soda solution |21 has been described as present in the seal trough |24, and this solurtion |21 is also present in the scouring box |20.

This caustic solution is supplied to these two containers by means of a pipe |30 having openings into both of these containers and which pipe is joined to a suitable source of the caustic soda solution indicated at |3|. A manually controlled valve |32 is disposed in the pipe |30 for admitting solution to the containers and |24 as desired.

Mounted in the side walls and spanning the distance between the same is a plurality of upper rollers |35 and a plurality of bottom rollers |36, the bottom rollers being above the liquid level in the bottom of the compartment 9. Also 25 the rear wall of the compartment 9 has an opening therein into which a container is adapted to be placed to completely fill the opening.

w together to form wash boxes.

The lower 'rollers which are mounted in the wash boxes formed by partitions |43, |46 to |52, inclusive, are indicated at |36 and instead of beingrmounted in side walls of the compartment are u mounted in the end walls and |56 joining all of the wash boxes together. It is to be noted that the walls |46 to |52, inclusive, are progres',- sively lower as they are stepped down from rear to front to allow the'water in wash box |46, for expartitions |46 and |41 and so on, so that the water will thus cascadeforwardly and finally flow over the wall |52 into the bottom of the compartment. This water in these wash boxes is sup- 35 plied fromrthe hot Water spray pipes 3 to H6,

fo |46; I

Disposed within one of'fthe wash boxes, forexinclusive, and it is thus seen that the most contaminated water would be inthe front wash box whereas the Vpurest water Would'be in `the rearmost box which is formed bypartitions |43 and ample between partitions |46 and |41, is a temperature responsive element which leadsvto a suitable thermometer |6l| on the outside of the This seal trough |24` 75 compartment so that an observer can ascertain This partition |43 prevents the hot water. issuing from the spray pipes I |3 to ||6 from fallthe temperature ofthe water inthe wash 'boxes at `any time desired.

The lower end of the compartment 9 has a drainvalve |52 .by means of-which the water can becompletely drained from the Vcompartment s. The seal 100x140 Vhas a drainfvalve i153 by means of which the=water can be drainedffromthe vbox MG. This boxvhas aninlet valve Ilii connected to a suitable sourcef-of :water .for `adn'iitii'ngaddiVM tional water ItEto the Vbox |48. All 'ofthe wash boxes formedzby the partitions |133 and it@ `to 52 have suitable drain .pipes connected toa common drain pipe |65 having 4a-drain valve it@ by means of which all of l"the wash. boxes canrbe drained into the compartment. 9 andin turn this water willdrain out ofthe drain valve E52.

The compartmentalso has mounted therein squeeze rollsiil and `i68through which the cloth C passes after passingfbeneaththe immersion roll Q28 and out of the seal box |26.

The seal box idd at vthe exit end of the compartment has mountedtherein.immersion rollers il@ and ill and above the seal box |45 .and on the exterior of the end wall l are mounted suitable brackets |13 in whichfsqueeze rolls i'irl and H5 are rotatably mounted.

Mounted in any suitable position but vshown as being mounted onV the side of the box :|291is -an electric motor Y|85 which hasa suitable sprocket wheel on its-motor shaft |3| on which is mounted a sprocket chain U22V w-hichV is also mounted yona shaft |83 -ex-tendingpfrom the first bottom roll 122. This shaft 83 also has a sprocket Wheel |34 thereon on which a sprocket chain |85 is mounted. This sprocket chain also engages a sprocket |85 on shaft |81 extending from the second lower roll |22. The third lower roll |22 has extending therefrom a shaft |83 on which a sprocket wheel |89 is mounted and on which also the chain |85 is mounted. This shaft |83 also has a sprocket wheel |95 secured thereon on which a sprocket chain ISI is mounted. This sprocket chain ISI engages sprocket |92 on shaft i'io, on which squeeze roll |52 is fixed and which extends to the exterior of the compartment and also engages an idler sprocket |93. The sprocket chain il also engages sprocket |91 on shaft |55 of the rst upper roll |35 which extends through the machine.

All of the upper rolls |35 have shafts |55 extending through the side wall lil of the compartment and each shaft has a sprocket ige mounted thereon. The shaft |95 of the front top roller |35 not only has the sprocket wheel |94 thereon but aiso has an additional sprocket wheel |91 thereon. Each of the sprockets |54 on shafts |95 extend-ing from the top rolls |35 are engaged by a sprocket chain |98, the upper portion of this sprocket chain |98 is the driving portion and the bottomV portion is the idler portion and would probably sag down somewhat from the position shown in Figure l1. At the extreme rear end of the machine, the last top roller shaft |55 has an additional sprocket Zilli thereon on which a sprocket chain 25| is mounted which is also mounted on a sprocket wheel 252 secured on shaft 253 extending from the lower squeeze roll V55 for imparting rotation to the squeeze rolls H5 and In the drawings and specifications, there has been set forth a preferred embodiment of the invention, and although Vspecific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being dened in the claims.
