ZDYIEING APPARATUS FOR HAT BODIES.

Application filed January 4, 1927, Serial No. 158,976, and in Czechoslovakia January 21, 1926.

In the case of known dyeing apparatus for hat bodies the hat bodies are stretched or spread out upon perforated hat-body cones, and are subjected to the dyeing operation while so stretched. The perforating of such cones takes up a great deal of time, for the sieve-like construction of such 'a cone requires a large number of holes, which have to be drilled individually in the hard material.

The invention consists in, utilizing as hat-body cone a cone which'is provided on its surface with grooves or channels for leading away'the liquor. Such grooves or channels have the advantage, as compared with the known perforation of the cone, that they can easily be milled or otherwise machined in the cone.

The leading away of the liquor by such grooves or channels on the external surface of the cone, arranged in the direction of the generating lines, renders possible the employment of flattened cones or flattenedc'one hat-body carriers for dyeing apparatus, this being a further feature of the invention. Such flattened-cone hat-body carriers could not hitherto be used for dyeing apparatus. It is not possible to construct such flattened cones as comparatively thin- Walled hollow cones, as is known for the known stretching cones of circular cross section, as they cannot support the pressure and must be compressed. In order to obviate this the walls of such flattened cones would have to be of great thickness, which would occasion great difliculties in the drilling, apart from the great length of such drilled holes, and the resistance occasioned by this length which opposes the flow of liquor through such long, narrow passages. Owing to the fact that according to the invention the passages for drawing off the liquor are made in the form of grooves on the surface of the cone their wall thickness no longer matters, and it becomes possible to employ solid cones.

The employment of flattened-cone bodycarriers has the advantage that in consequence of the small amount of space they take up a plurality of such carriers can be united within one bell, in which only a single circular cone could be lodged. The capacity of such dyeing apparatus can thereby be considerably increased.

In the drawing is diagrammatically illustrated in Figure l a hollow cone of circular cross section with channels or grooves run ning round it, and in Figures 2 and 3 a cone with channels or grooves runnnig in the direction of its generating lines Figs. 4 and 5 are section and plan views of a flattened type of cone.

In Figure 1 the hollow cone a serving for the stretching of the hat bodies is provided with channels'or grooves?) in parallel circles, which are connected at various points with the hollow interior of the cone A by drilled holes (Z. The grooves or channels are arranged at such distances from one another that all parts of the surface of the cone are exposed to the suction effect of the pump producing the circulation of the dye liquor.

Such a construction of the cone has the advantage, as compared with the known sieve-like construction of the cone, that there are considerably fewer holes (Z to be drilled.

In the constructional example of Figures 2 and 3 a flattened cone is shown.

a is the flattened-cone carrier, in the surface of which channels 72 are made, which serve as passages for drawing off the liquor.

Above the margin 0 of the body, which is v drawn in dotted lines, the connection of the channels 79 is made by means of drilled holes (Z with a central cavity 6 which may however be very shallow and need not be deeper than is required for the connection with the holes al In this manner the connection of the channels with a common discharge passage may be made.

Obviously instead of one cavity 6 several such cavities may be employed, in such a way that a plurality of channels are comprised by a common discharge passage.

In order to prevent the hat bodies from being pressed into the grooves b or b during the dyeing, it is advisable to stretch over the cone a or a a permeable covering f, on which the hat body can bear with its entire internal surface. Such a covering may consist of a jute fabric, wire netting or the like, which is stretched upon the cone and results in the hat bodies not s gging over the channels.

The addition to the dyeing apparatus may be effected in the same manner as is known for the circular stretching cone.

One constructionalexample of dyeing apparatus with flattened cones is diagrammatically illustratedin Figures 4: and 5.

IVithin a hell 1 forming the dyeing vessel which the liquor enters under pressure through the liquor inlet 2, are arranged for example several of such flattened-cone hatbody carriers a side by side, from Which the liquor can escape in the centrethrough the cavity 6 Since these flattened-cone body-carriers only take up a. little space, and a plurality of such carriers can be arranged (Figure 4) inside one hell 1, a means is provided for raising the capacity of the dyeing apparatus.

What I claim is:

1. Dyeing apparatus including a cone serving for the stretching of a hat body pro vided on its surface With channels which form the passages for the discharge of the dye liquor. v

2. Dyeing apparatus according to claim 1, characterized by the feature that the channels forming the passage for the discharge of the dye liquor communicate through holes With a cavity in the cone.

3. Dyeing apparatus according to claim 1, characterized by the feature that the channels run along parallel circles.

4. Dyeing apparatus according to claim 1,

characterized by the feature that holes communicating with a cavity in the cone are arrangedwithin the surface covered by the hat body.

5. Apparatus according to claim 1, characterized by the feature that for all the channels a common discharge passage is provided, which is formed by a cavity in the cone.

6. Apparatus according to claim 1, characterized by the feature that upon the cone,

over the channels, a permeable covering is stretched, 1n order to prevent the hat bOdlQS.

8. Apparatus according to claim 1, characterized by the feature that the right, cross sect-ion of the cone serving for the stretching is elliptical.

In Witness whereof I have hereunto signed my name.
