2 Claims.

My invention relates to treating textile material or cloth and more particularly to decatizing cylinders about which the cloth is wound for treatment. K

In the steam treatment of textile material or cloth, it is customary to wind a blanket and the cloth about the peripheral Wall of a decatizing or steaming cylinder in order that steam from within the cylinder may be applied to the cloth through perforations formed in the treating zone of the peripheral wall. Should water, occasioned by the condensation of steam within the cylinder, seep through the perforations and engage the cloth, a spotting or discoloration of the cloth would occur and thus depreciate the value of the cloth, the sections thus spotted or damaged being removed and discarded. One solution to the problem of preventing damage of this character to the cloth is to provide the cylinder with a plurality of radially extending tubes having their outer ends threaded into the perforations and with the tubes being of a length to position their inner ends above the level of any Water which accumulates in the cylinder to preclude leakage of Water through the tubes, an example of constructions of this character being disclosed in U. S. Patents Nos. 364,593, 1,047,683 and 2,085,222.

However, inasmuch as each of the perforations in the peripheral wall has to be tapped and the end of the tube for insertion therein threaded, in order to effect a rigid and tight iit, it will be apparent that a decatizing cylinder thus fabricated is extremely expensive not only in initial construction, but with respect to maintenance in the replacement of tubes which often become damaged and/or have their outer ends broken and remaining in the perforations,

One of the objects of my invention is to provide a decatizing cylinder which is constructed and arranged in a manner as to eliminate the aforementioned water baiile tubes and at the same time preclude seepage of water from within the cylinder into engagement with the cloth being treated.

Another object of my invention is to provide a decatizing cylinder of the foregoing described character which is simple in construction, durable in use, efficient in operation and economical in manufacture and maintenance.

With the above and other objects in View, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings from which the several features of the invention and the advantages at- 2 tained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like reference characters designate like parts throughout the several Views:

Figure l is a longitudinal sectional View of a decatizing cylinder constructed in accordance with my invention, the arms for supporting the steam chest being transversely transposed for clarification.

Figures 2 and 3 are sectional views taken on the lines 2-2 and 3 3 of Figure 1, respectively.

Figure 4 is a longitudinal sectional View of the cylinder illustrating a .modiiied construction.

Figure 5 is a sectional view taken on the line 5 5 of Figure 4.

In practicing my invention, as illustrated in Figures 1 to 3 inclusive in the drawings, I provide a decatizing cylinder 5 for use in conjunction with apparatus for treating textile vmaterial or cloth and which cylinder comprises a hollow cylindriform body having a circumferential wall 6 and sinistral and dextral end walls 'I and 8, the end walls 'I and 8 serving to seal .the respective ends of the body and having xed Vthereto centrally disposed bearing seals 9 and I0, respectively. The seal 8 has extending therethrough and in xed relation thereto a tubular member I I constituting a shaft which is rotatably mounted in a stationary bearing member I2, While a steam conduit I3 extends through the seal I0 in fixed relation therewith and constitutes a shaft which is rotatably mounted in a stationary bearing member I4, thus, permitting rotation of the cylinder relative to the members I2 and Ill.

Disposed within the cylinder 5, in spaciality with the walls 6, 'I and 8, is a cylindrical steam distributing chest defined by a circumferential wall I5 and end Walls I6. The ends of the wall E5 are provided with flanges F secured to the circumjacent margins of the walls I6 by means .of nuts and bolts or the like. The walls I6 are lconnected to rings R, secured to the inner peripheral face of the wall 6 by means of spaced arms I'I whereby the chest is maintained Yinthe vaforesaid spaciality. Each of the Walls I6 is :provided with a plurality of ports I8 for permitting the passage of steam from within the chest to within the :end sections of the cylinder 5, the conduit I3 extending into the chest, through the adjacent wall I6, for introducing steam into the .chest as .hereinafter more fully described.

In close proximity to the walls I and 8, the inner peripheral face of the Wall 6 ofthe cylinder 5 has secured thereto a pair of baille rings I9 and 26 which define a material treating zone about the cylinder with the peripheral wall being perforated as at 2| throughout the length and width of the zone. The rings l@ and 28 coact with the walls 'l and 8 to define sinistral and dextral condensing chambers 22 and 23 within the end sections of the cylinder, respectively, and with each other to define a dry steam chamber 24 between the charnbers 22 and 23 and about the peripheral wall l5 of the steam chest for supplying steam to textile material, wound about the treating zone, through the perforations 2l according to customary practice.

The end walls l and 8 are each provided with a drain cock 25 for draining liquid, occasioned by the condensation of steam, from the chambers 22 and 23. The tubular member l l extends through the adjacent Wall l@ of the steam chest and is provided therein with a pair of lateral branches or pipes 3U. The outer ends of the pipes 30 are provided with scoops or buckets 3l each being provided with a baffle partition 32 at its lower end whereby liquid or water lifted therein will drain through the pipes 3Q towards the member l l and not be discharged through the opposite side of the respective scoop, it being understood that the tubular member is longitudinally and centrally divided by a partition 33 to provide a pair of compartments communicating with the pipes 3@ respectively. As the cylinder, steam chest and scoops 3i rotate in unison, it will be apparent that any liquid, for instance, water condensed from steam, within the bottom of the chest will be scooped therefrom and discharged through the member Il.

In operationassuming a blanket and textile material is wound about the treating zone of the cylinder in the usual manner-steam is introduced into the steam chest through the conduit i3 and thence passes into the chambers 22 and 23 through the ports i8, the steam, thus introduced into the chest, at the same time effects heating of the peripheral wall l of the chest and water, produced by condensation within the chest, is discharged by means of the scoops 3l through the tubular member il during rotation of the cylinder. Steam from the chambers 22 and 23 passes into the chamber 24, between the circumferential faces of the baiile rings i9 and 2B and the peripheral wall I5 of the steam chest and thence through the perforations 2l of the wall 6 to treat the material disposed thereabout, it being understood that the heated surface of the Wall l5 effects drying of the steam within the chamber 2e to preclude condensation therein and thus eliminate spotting or discoloration of the textile material being treated.

If desired, and as illustrated in Figures 4 and 5 of the drawings, siphoning means may be provided for siphoning the water from the chest and the chambers 22 and 23. In a construction of this character, the tubular member li and scoops 3l have substituted therefor a siphoning pipe Il!! which constitutes a shaft which extends through the sinistral end walls l and i6 of the cylinder and chest and which pipe it is provided with a T 4l to which is secured a tube :i2 for siphoning water from the chamber 22. The inner end of the pipe lill is provided with an elbow 43 having connected thereto a tube le for siphoning the water from Within the chest. The seal l0 has extending therethrough a stationary bearing member 45 which in turn has extending therethrough and in nxed relation therewith the conduit i3 and a siphoning tube i6 which terminates within the chamber 23, lt being understood that the tube i5 and pipe 40 are connected to suitable siphoning means eiective for removing the Water from the steam chest and the chambers 22 and 23 when rendered operative.

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined to the herein described use therefore as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles involved which are capable of extended yapplication in various forms, and the invention comprehends all construction within the scope of the appended claims.
