CYLINDRICAL DRYING APPARATUS Filed March 16, 1952 FIG/1.

Patented July 24, 1934 PATENT OFFICE OYLINDRICAL DRYING APPARATUS Gerrit Jan Hermanus van Kuyk, The Hague, Netherlands Application March 16, 1932, Serial No. 599,297 In the Netherlands March 19, 1931 2 Claims.

This invention relates to improvements in cylindrical drying devices, such as are employed in supporting wet sheet material, such as dyed cloth, during the drying of the material. Such devices 5 are ordinarily constructed of open woodwork; a device so constructed cannot withstand rough usage and the wood absorbs dye from the previously dried material and imparts the color to the subsequently dried material.

The object of the present invention is to construct the device of metal, to provide the required strength to withstand rough usage and which will not absorb dye to discolor a subsequently dried fabric. To accomplish this object the cylindrical drier is constructed of metal rods, suitably shaped and assembled for the purpose.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing. Al-

though in Fig. 1 of the drawing only one typical form of the invention is illustrated, many other embodiments of the same are possible.

Fig. 2 shows a modified form of construction of an element.

Referring firstly to the construction of the cylindrical drying device or drying-stick shown in Fig. 1, the stick comprises a number or plurality of metal wires, bent in the required form, these wires being connected together at their ends by means of binding with iron wire, by soldering or in any other manner. The metal wires thus are adapted to form together a cage with a cylindrical outer-surface and opposite heads having projecting end supports alined with the axis of the cylindrical cage.

In order to reinforce the drying-stick, the wires may be connected together also in one or more points between their ends, either by bending the wires in a special form or by means of additional connectingor reinforcing-members. These members may be formed as a fiat or hollow cylindrical piece or have any other suitable form known and easily ascertained by those skilded in the art.

Fig. 2 of the drawing illustrates a wire which has such a form that it may easily be connected to the other wires of the same shape in points located between the ends. By forming the wires in a zigzag line and connecting the collapsingpoints of the adjacent Wires it is possible to give the cylindrical surface of the drying-stick a netshaped structure.

The drying-sticks according to the invention more particularly are adapted to be used with success in the drying or so-called smoking of rubber-sheets.

A further feature of the drying-sticks consists in that the sheets hanged thereon are into touch with the material of the sticks only by a very small part and therefore are only to a very small surface withdrawn from the drying action of the air or the gases.

What I claim is:

1. A cylindrical drying device comprising a plurality of rods having intermediate parts arranged parallel to and offset from the axis of the cylindrical device and with the intermediate parts spaced apart around the periphery of said device, said rods having both of their end parts extending inwardly to provide heads for the cylindrical device to offset the intermediate parts from the axis of said device and with the extremities of the end parts extended in assembled parallel relation to the axis of the device, and means for binding together the assembled extremities of the end parts to provide projecting end supports alined with the axis of the device.

2. A cylindrical drying device as claimed in claim 1, in which the intermediate parts of the rods include lateral projections to provide means for securing the rods together around the periphery of the cylindrical device.
