SPECIFICATION forming part of Letters Patent No. 323,819, dated August 4-, 1885.

Application filed March 27, 1885. (No model.)

To all w/wm it may concern:

Be it known that 1, WILLIAM llIATI-IER, a citizen of England, residing at Salford, in the county of Lancaster, England, have invented apparatus for soaking, boiling, or dyeing textile materials or subjecting them to the action of liquids or gases, (for which I have made application for Letters Patent in Great Britain, dated th March, 1885, No. 3,096,) of which the following is a specification.

The soaking and boiling of textile materials for cleansing, bleaching, and dyeing operations are usually effected in kiers or vessels in which the material is piled in mass and sub- 1 jected to the action of liquor, boiling liquor and steam. Owing to the difficulty of penetrating the mass, the process must be continued for a long time, and the action is by no means uniform over the whole of the material. Moreover, a long time is occupied in charging the kier before the action can be commenced, and afterboiling has terminated the kier is cooled down in the operation of emptying it, which also occupies a long time and involves great waste of heat.

My invention relates to means of avoiding the disadvantages attending the present system of heating the material by the use of apparatus whereby I am enabled to abridge the time and to economize the labor and heat re quired, and at the same time to secure great uniformity of treatment throughout the whole of the material operated on.

Figure 1 of the accompanying drawings is a longitudinal section, partly in elevation, and Fig. 2 is atransverse section, of apparatus according to my invention, which, by way of illustration, I will describe as applied for boiling.

A is a cylindrical vessel, like aboiler, placed with its axis horizontal. It is made with a double shell, forming round it an annular steam-jacket, B. At each end it is fitted with a vertically-sliding door, 0, arranged like a wedge sluice-valve, which, when pressed down its inclined guides, tightly closes the end of the vessel. In the lower part of the vessel are fixed rails R, on which run open-framed or lattice trucks T, which are made of shape approximately corresponding with the interior of the vessel A, but smaller, so as to leave space all round them within A. The metal of these Patented in England March 10, 1885, No. 3,096.

trucks should be enameled, or otherwise coated, so as to prevent soiling of the material which they contain. In the lower part of the vessel, at the sides and ends, are fixed partitions P, nearly fitting to fillets on the trucks T, so" that, when the trucks are in position, these act as stops, preventing free flow of liquor around them.

. S is a steam-boiling pipe, perforated with numerous holes and extending along the bottom of the vessel. L is aliquor-pipe, extending partly along the top and terminating in distributing-nozzles N. From the pipe L a branch, L, leads to a supply-cistern, and a branch, L leads to the discharge of a rotary or other circulating pump. From the bottom of the vessel Athere is a pipe, M, which leads by one branch to a drain or other outlet and by another branch to the suction of the circulating-pump. D is a steam-pipe supplying the jacket 13, andE is a pipe for running off water of condensation. The pipes S, L, D, and E, and their branches are supplied with suitable cocks or valves.

F and G are pipes leading to safety-valves for the jacket B and the interior of A, respectively. At each end, outside thevessel, are continuations of the rails R,with suitable bridgepieces 0, that can be folded down when the doors 0 are raised.

Several sets of the trucks T being provided, the operation is carried on in the following manner: A pair of the trucks T, which have been charged outside with the material to be operated on, are run on the rails into the vessel A, and the doors Gare tightly closed. The casing 13 is supplied with steam and a quantity of suitable liquor run into the vessel by the pipe L, enough to cover or partially cover the trucks and their contents, is heated and kept hot by the steam in the jacket Band steam blown through it from the pipe S. By means of the circulating-pump the liquor is kept in circulation, being drawn from the bottom of the vessel by the pump branch of the pipe M,

and discharged by the nozzles N, which distribute the liquor over the material in the trucks. As the liquor in circulating from top to bottom finds no free passage outside the trucks, being impeded by the partitions 1?, it has to find its way mostly through the mateof that pair.

rial in the trucks,which is also kept in a bath of the boiling liquor,surrounding it on all sides. \Vhen the boiling has been continued for such time as may be required,the liquor is run off by the drain branch of the pipe M, the doors 0 are raised by a steam, hydraulic, or other crane, the trucks T are run out at one end of the vessel, and another set of trucks, ready charged, are run into it at the other end to have their contents operated upon, as above described. The trucks that have been run out of the vessel can be unloaded andloaded again while the boiling of the material in the other trucks goes on, and thus little time is lost, and there is no material cooling of the vessel during the eX- change of trucks.

The vessel A,in d of having doors at both ends, may have a door, 0, only at one end, the other end being permanently closed, and this closed end may be steam-j acketed. The trucks in that case would be withdrawn and introduced at the one end only.

Ihave shown in the drawings a pair of trucks in use and a boiling-vessel suited for reception It is, however, to be understood that the number and dimensions of the trucks may be varied, and the boiling-vessel may be made to accommodate only one truck or a number greater than two.

When the apparatus is used for boiling woven fabrics, these may be charged in rope form into the trucks. It is, however, in many cases preferable to treat fabrics spread out to their full width, which cannot be conveniently done in ordinary kiers. In trucks, such as I have described, fabrics can readily be laid to expose their full width, either folded or wound on rollers.

Obviously, for soaking or dyeing, the same apparatus is applicable. \Vhen the material is to be soaked in cold liquor, the heating by steam is dispensed with. \Vhen the material is to be dyed or acted on chemically by liquids, the dye or liquid is run in, and should it require to be heated, this may be doneby admitting steam to the casing B or blowing steam through the liquid, or both; also, when the material is to be exposed to the action of gasessuch as sulphurous acid, chlorine, carbonic acid,and othersthese gases may be introduced by the steam or the liquor pipes, or may be made to circulate through the vessel by admitting them by the one pipe and allowing them to pass out by the other.

For processes not requiring heat, the vessel A may be made without a steam-easing, B.

I am aware that boiler-tanks have been provided with trucks for use in various arts; and such, therefore, I do not broadly claim.

Having thus described the nature of my invention, and the best means I know for carrying the same into practical effect, I claim- 1. The combination of the vessel A, provided withatrack, It, alattice or open-framed truck, T, to run over said track, and a sliding wedgeshaped sluice'valve door, 0, to close the opening at the end of the vessel, substantially described.

2. The combination of the vessel A, provided with a track, It, a truck, T, to run over said track, and a partition, P, in the lower part of the vessel about the truck, substantially as described.

8. The combination, with the vessel A, of the lattice or open-framed truck T within the vessel, the partitions P in the lower part of the vessel about the truck, and pipes L, provided with nozzles N, and the exit-pipe M for maintaining a circulation of liquid through the vessel, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of March, A. D1885.

\VILLIAM MATIIEIR.
