To @ZZ 1li/"tom may concern.

Be it known that l, Envn C. rrnronrnin, a citizen of the United States, ani resident of San Jose, in the county ot Santa @lara and State of California, have invented a certain new and useful improvement in Electric Heaters, ot which the following is a specilication.

My invention relates particularly to an electric heater adapted to be used in combination with pleat-ing irons such as are used in laundries.

It is an object of my invention to provide a heater ot the character indicated which can be plugged into the regular electric light systems and which is so constructed as to use a minimum amount of current consumption for the heat required. Also the device is so constructed as to be easy to mamita@n ture, simple in operation, and serve as a stand and holder tor the pleating irons when not being used.

It is also an object to provide a. heater which will prevent the over heating of the irons and the consequent scorching oithe materials to be pleated.

In the drawing Figure l is a front elevation of the heater.

Figure 2 is a side elevation ot the same showing the Ventilating oriiices as well as a pleating iron in place on the iron holder.

Figure 3 is a` plan view of the heater.

Figure 4 is a cross-section on line 4 of Figure 2 showing a pleating iron in position for heating.

Referring more particularly to the drawings, I show a sheet metal container having two sides as 1-2, a bottom and top as Stil and the front and back as 5-6 respectively. The whole being formed as shown and mounted upon supporting members 7.

Sides l-2 have suitable orifices as 99-9-9 and openings l0-l0 which as ventilators for the heating elements llmllhll. Said heating elements are formed of insulating and heat resisting inaterial such as porcelaim with collars 12-12-12 extending outwardly therefrom at one end. The inner openings 13-13-13 of said heating elements are of su'Hicient size as to allow the entrance oiz the largest size pleating irons used as shown at lt. l-leatN ing elements llwll-ll are inserted through suitable openings in the front side 5, the collars l2-l2`lf2 holding the same in position. These elements are lwound with suitable resis'n ice wire as l5 and are connected in series a; shown, the two leads 16-17 being connected to standard plug terminals lon-i9 which are insulated from and pass through suitable openings in the baci; d ot said container.

front 5 of the container is extended a dist: 1 e above the tcp as shown at 20 and has grooves 2l-2l2l cut therein to receive the 1eating irons when not in use as shown in igure 2, said grooves 2l-2l21 being on a line with the openings l3-l3-l3 ot heating elements il-ll-l1- rhe operation ot the device being as tollows The plug elements 1,8`l9 being connected to the electrical circuit through the medium oit the standard cord and plug such as is used on electric irons, which is not shown, the current passes thru wire 16, resistance wires l5-l5`15 and wire 17 thus heating the said resistance coils. This heat is taken up by the pleating irons which are placed in openings lShlS-LLS, the container being cooled by means of ventilating orifices 9-9-9 and openings l0-10 in the sides 1 2. if it is desired to use only one iron and vthe other two are already heated the same can be removed from the heating elenient and placed in grooves 2li-2l on the top ot the container. The heat radiation from the elements and from the top ot the container is su'liicient to hold the heat ot the irons placed thereon tor a considerable length of time. Thus it can be seen that the irons can be kept hot and yet all danger from excessive overheating is avoided by the proper use of the device.

it is to be understood, oit course. that while have herein shown and described one partici'zlar embodiment oit my invention. that changes in form and construction may b'e made within the scope of the appended claim.

device of the character indicated comprisingv a stand of heat conducting material having a closed top and Ventilating means arranged in the upper part of its side portions, a plurality of tubular elements ar- D im l.

ranged in a horizontal plane Within said stand, each tube having an open end communieacing` with the front of said stand Wherehy to receive pleating irons, and heating elements Wound around said tubes and operatively arranged in an electrical circuit, the front of said stand extending a distance above the top thereof and having a plurality of notches formeel therein adapted to receive and Support the handle end of the pleating irons, when not in use or in Said tubes.

ERVE C. STR-ICKLAND.
