ELECTRIC DRYING AND IRONING APPARATUS- Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed March 28, 1905. Serial No. 252,592.

TO/(ZZZ whom it may concern:

Be it known that I, GEORGE W. RICHARD- SON, a citizen of the United States, residing at Wissahickon, in the county of Philadelphia, State of Pennsylvania, have invented certain Improvements in Electric Drying and Ironing Apparatus, of which the following is a specification.

This invention relates to apparatus designed particularly for electrically drying and ironing blue-print paper; but it is also adapted for drying and ironing various other ma terials. It avoids the present use of wringers and drying-boxes and effects a material saving in time and labor.

The nature and characteristic features of the invention will fully appear by reference to the following description and the accompanying drawings in illustration thereof, of which Figure 1 represents a top plan view, par tially in section, of an apparatus embodying my improvements. Fig. 2 represents the same in rear elevation and partial section. Fig. 3 represents an end elevation thereof. Fig. 4 represents a transverse vertical sectional view thereof, and Fig. 5 represents a sectional elevation of a roller and its.connections.

As shown in the drawings, the base 1, adapted to be connected to any suitable support, carries the casing 2, preferably made of rass. The casing ends 2 have journaled therein the rollers 3, and the material of the body is formed in the curves 2 conforming to the rollers and providing an inlet i and an outlet 5, connected by a passage 6 for passing the paper between the rollers. The inlet is provided with a guide-plate 7 and with the roller 8, mounted in the struts 9, supported by the casing, for feeding the material.

The channel 6 is formed by the plates 10, supported by the plates 1 1 and 12, connected with the casing, the lower part of the plates 11 being bent to conform to the contour of the rollers. The space within the plates 10, 11, and 12 is packed with heat-insulating material 1 3, and the spaces occupied by the rollers 3 are lined with heat-insulating material 14.

The rollers consist of the hollow brass cylinders 3*, supported by hubs 3 journaled in roller-bearings 2, carried by the ends of the casing. Within each cylinder 3 is a cylinder 3-, of insulating material, supported by the hubs 3 and wound with fine wire 3 The wire is connected with a ring 3 attached to the part 3 projecting from the hub, by the insulating-ring 3 the ring and the wire throughout the length of the coil being insulated and the coil being grounded at its termination in any suitable way, as by the connection 3 Brushes 15 bear upon the several rings 3 and are supported upon the insulating-bearings 16, the several brushes being connected by the binding-posts 17 with conductors 18.

The several rollers have pinions 19 fixed to the ends thereof, the vertical pairs of rollers having their pinions in en agement.

A pinion 20, driven by the s aft 21, meshes with a corresponding pinion of each vertical pair, so that the rollers may be operated by the shaft 21 to feed the paper therethrough.

It will be understood that in the operation of this mechanism the paper has the water and moisture squeezed and dried therefrom by passing it through the rollers 3, revolved together by the shaft 21 and heated by currents passing through their respective coils.

Having described my invention, I claim 1. In apparatus of the class described, drying and ironing mechanism comprising a plurality of rollers coacting to press and dry material passed therethrough, each of said rollers comprising a brass ironing-cylinder, a resistance-coil therein adjacent thereto, bearings for said rollers, a conductor connected to and revolving with each of said rollers, means for insulating each of said. conductors from the respective cylinders and bearings, and a brush making contact with each of said conductors in combination with a casing having end walls disposed between said ironing-cylinders and brushes, substantially as specified.

'2. In apparatus of the class described, a casing having a passage therethrough, and a plurality of rollers journaled in said casing and coacting to press material in said passage, the respective rollers comprising a brass ironing-cylinder and a resistance-coil located in and concentric to said cylinder, substantially as specified.

3. In apparatus of the class described, a casing having closed ends, ironing rollers j ournaled in said ends, the body of said casing conforming to said rollers and forming passages thereto, and therefrom, and a resistance-coil in each of said rollers, substantially as specified.

4:. In apparatus of the class described, a casing. having closed ends, ironing rollers journaled in said ends, and a guideway in said casing between pairs of said rollers, said casing having an inlet to and an outlet from said rollers and guideway, substantially as specified.

5. In apparatus of the class described, a casing having closed ends, ironing-rollers journaled in said ends, plates supported by said casing and forming a guideway between pairs of said rollers, and feeding mechanism
