UNITED STATES ANTON M. RASMUSSEN, F ROCKFORD, ILLINOIS.

ELECTRIC IRON.

Application filed 0ctober25, 1921.

To all whom it may concern:

Be it known that I, ANTON M. RAsMUs- SEN, a citizen of the United States, residing at Rockford, in the county of WVinnebago and State of Illinois, have invented new and useful Improvements in Electric Irons, of which the following is a specification.

This invention relates to electric irons and an object of the invention is to provide an electric iron of the mangle type wherein the clothes or fabrics are ironed by means of a heated roller to which the articles to be ironed are fed by an endless apron or belt.

Another object of the invention is to pro vide an electrically heated iron that can be heated while in operation and one which provides a greater ironing surface or area than the average approved type of rotary ironers permitting greater efficiency in the ironing of the clothes.

A further object of the invention is to provide an ironing machine as specified wherein pressure is applied evenly to the articles being ironed, a plurality. of pressure springs being provided which owing to their yielda-bilit will prevent the crushing or breaking of s ell buttons or the like.

Other objects of the invention are to provide an ironing machine wherein the work is fed to the ironing roller automatically eliminating danger of catching the operators fingers and eliminating slippage or diagonal pulling on the work, and an iron which is particularly adaptable for fine fabrics such as silks, ribbons, laces and the like as well as collars, ties and other articles of Wearing apparel.

Other objects of the invention will appear in the followin detailed description taken in connection with the accompanying drawin wherein:

ig. 1 is a side elevation of the'improved ironing machine.

Fig. 2 is a vertical section through the ironing machine.

Fig. 3 is an end elevation of the ironing machine.

ig. 4 is a fragmentary longitudinal section through the ironing roller.

Fig. 5 is a cross section taken on the line 5-5 of Fig. 4.

Serial No. 510,262.

Fig. 6 is an enlarged detail view illustrating the electrical connection with the heating elements in the ironing roller.

Fig. 7 is a section taken on the line 7.7 of Fig. 6.

Fig.8 is a detail section taken on the line 8-8 of Fig. 6.

Fig. 9 is a detail cross section through one of the endless belt guiding rollers.

Referring more particularly to the draw ings, the improved ironing machine comprises a supporting structure 1 which carries a plurality of blocks or bearings 2. The said bearings being slidably supported by suitable guide rods as indicated at 3. Pressure springs 4c are provided which engage the bearing blocks 2 for yieldably urging the bearings away from the adjacent portions of the frame 1 for moving the

belt carrying rollers

5, 6, 7, 8, 9, 10 and 11 which maintain tension on the belt or apron 12. The respective rollers have trunnions 13 carried by their ends, which extend into the bearing blocks 2 for rotatably supporting the bearings. Suitable nuts 14 are provided for regulating the tension of the various springs 4:.

The apron or belt 12 is endless and travels from the roller 5 over the rollers 6 and 7 from where it is returned to a point below the roller 6, passing about the ironing roller 15, passing from the ironing roller 15 to and about the rollers 10, 9 and 8 respectively.

Any suitable type of power transmitting mechanism as indicated at 16 may be provided for rotating the respective rollers and the ironing roller 15. Power may be supplied from an electric motor or suitable prime mover as indicated at 17. The roller 11 is positioned in the same horizontal plane as the ironing roller 15 as clearly shown in Fig. 2 of the drawings, and an endless belt or apron 18 passes about the roller 11 and the ironing roller 15 so that as articles of clothing or work to be ironed travels with the belt or apron 12 in the direction indicated by the arrow A it is fed between the converging portions of the belts 12 and 18, and is carried about the ironing roller 15 passing about substantially one-half the surface area of the ironing roller and thereby will be thoroughly ironed. They work is then delivered beneath the roller 11 at the point where the belts or aprons l2 and 18 diverge as indicated at B in Fig. 2 ot' the drawings.

The ironing roller 15 comprises an outer steel shell 20 which is formed of

sections

21 and 22 each being semicylindrical in shape. The

sections

21 and 22 encloses the heating elements 23 which are made in sections in the approved form of making electric heating elements, comprising resistance wires 24 through which the current is passed to provide the necessary heat. The sections of the heating elements 23 are held in place by screws 24: which extend through the easing 20, heating elements-23 and into the cast iron core 25 of the iron roller structure 15.

The current is passed to the wires 24, and the heating elements through the conducting wire 26 and returned therefrom through the wire 27. The

wires

26 and 27 are connected by means of binding nuts 28 to the ends of

connectors

29 and 30. The

connectors

29 and 30 are similar in construction, each comprising an angled rod 31 of copper or analogous conductive material which extends through a sleeve 32 of insulating material carried by the end 33 of the ironing cylinder or roller structure. The nuts 34 are threaded on the angled members 31 to prevent movement of the angled members relative to the ironing cylinder or roller.

The outer ends of the members 31 project into yokes 36 which carry rollers 37 and the yokes 36 are urged outwardly on the members 31 by spiral springs 38 which urge the rollers 37 into engagement with the respective rings 39 and 40. The rings 39 and 40 preferably have their perimeters rounded and the rollers 37 are provided with concave perimeters so as to engage the rings 39 and 40 and prevent lateral movement of the rollers relative .to the springs. The rings 39 and 40 have connection with a suitable electric supply source through the medium of suitable connecting

posts

41 and 42 which are carried by a suitable brace 43. The rings 39 and 40 are braced by bracing posts 44 which are similar in construction to the

braces

41 and 42 except that no electric conducting, wires as shown at 45 are connected thereto. The bracing post 44 is disposed diametrically opposite to the electric conducting post carried by the same ring.

From the foregoing taken in connection with the drawings it will be apparent that the current may be fed to the heating elements 23 during rotation of the ironing roll, rolling contacts being provided by the rollers 37 and rings 39 and 40 which will permit the heating of the ironing roll .durmg use.

Certain of the belt guiding rollers are constructed of wood and some of these against rollers have their surfaces padded as indicated in Fig. 9 of the drawings. The padded rollers having layers 47 of cork or rubber about their outer surfaces over which is wound cotton padding 48, the said cotton padding being confined by strips of fabric as. The fabric 49 and cotton padding 4-8 is wound upon the rollers in such a manner that the rollers can be replaced without dismounting them.

From the foregoing description taken in connection with the accompanying drawings it will be apparent that an lroning machine has been provided which is particularly adaptable for ironing fine fabrics one which will properly iron the fabrics, providing a maximum ironing surface and also that the improved ironing machine is so constructed that the ironing cylinder may be heated during use, the heating elements being disposedtherein in such a manner as to permit their renewal when worn out.

It is, of course, to be understood that the invention may be constructed in various other manners and the parts associated in difi'erent relations, and therefore, I donot desire to be limited in any manner except as set forth in the claims hereunto appended.

Having thus described my invention what T claim is:

1. In an ironing machine, an ironing roller comprising an inner core, electric heatin elements about said core, and a removab e metal shell enclosing said heating elements, binding posts carried by said shell and having connection with said heating elements, contact rollers connected to said binding posts, conducting rings adapted to have communication with an exciting source, said rollers engaging said rings to permit energizing of said heating elements durin rotation of the ironing roller.
