ELECTRIC HEATER.

Patented April 27, '1909.

, Application led November 29, 1907. Serial No. 404,209.

To all whom it may concern.' Be it known that I, GEORGE E. STEVENS, a

Lynn, in the county of Essex and State of Massachusettsxhave invented certain new and useful Im rovements in Electric Heaters, of which t e following is a specification.

This invention relates to electric heaters and has for its object the provision of a de- 'vice of this character ada ted for atmospheric heating urposes,-w ich is self-contained and simpe in construction and at the same time thoroughly reliable, safe and efficient.

My invention relates more specifically to ,the production of an electric heating device of the type known as a foot warmer, one of the objects being to produce a heater which isin the nature ofa foot rest, which may be 'move'd from place to place, and which is strong and at' the same time of alight construction.

My invention therefore consists of the features of construction and the arrangement and combination of elements hereinafter set forth.

In the acoompanyingdrawings in`which I have shown my invention embodied in a concrete structure, Figure 1 is ,a plan view partly in section of one formdof my invention; Fig. 2is a'sectional view of the same taken on the line 2 2 of Fig. '1; Fig. 3 is a plan view of a modified form of my invention; and Fig. 4

is an end view partly in section of the same.

Referring to the drawings (Figs. 1 and 2) 10 re resents the sides of a box, preferably of meta having a bottom or base 11`-secured thereto made of some material, such as wood, the bottom surface being preferably of felt 12. The box is open at the top and an electric heating unit 13 of an elongated type, as shown, is mounted longitudinallyfand centrally of the box. This unit is preferably mounted in bearings 14 so as to revolve therein. The unit may be of any desired type but the particular structure forms no part of my invention. For purposes of illus-- tration I have shown the unit of the type described and claimed in my previous patent No. 803,795. The leads for this heating unit are brought in through the insulating sleeve 15 and are connected at opposite ends of the unit by means of the terminals 16, each adapted to cooperate with a socket 17.

casing in the form of wings 19' mounted on rods 20 which pass through the'ends of the strips. The wings 19 are bent in the arc of a circle of which the axis' of the unit 13'is the center, and the sides of the box are brought in to meet this wing so as to make a close joint and prevent air from going out exce t through the space between the strips. T e ends of the wings are bent into the form of a stop 21 sol as to limit the movement of the Strips. f These strips are of thin metal and so shaped that they will conduct the heat from the unit out to their ends so that when the current is turned on, the strips will be heated throughout their length and the feet may be warmed by placing them thereon. The angle of support may be changed b a sim le movement of the ankles which wi shift t e top on its pivot.

Figs. 3 and 4 show another form of the device in Whichthe top of the box is arranged' at a iixed angle. In this case the top 22 is arranged at the inclination shown and the These stri s have a length has the eect of causing the heat to difuse as it is limited by the scope of the claims annexed hereto.

What I claim as new and desire to secure by Letters Patent of the United States, is-

1. An electric heater comprising a box having a movable apertnred top, and an electric heating device arranged 'to distribute heat throughout the area of said top.-

2. An electric heater comprising a box having a pivoted apertured top and an electric heatmg device arranged to 'distribute heat throughout .the area of said top.

3. An electric. heater comprising a box-- having an apertured top consisting off an' elongated heating unit and spaced strips in heat conductive relation thereto.

4. An ectric. heater comprising a box having an apertured top pivoted for movement in a vertical plane, an elongated heating unit extending centrally thereof, and means for distributing the heat throughout the area of said top. i

5. An electric heater comprising a box having an apertured top consisting of an elongated heating unit and spaced strips in heat-conductive relation to the unit'pivoted for movement in a vertical plane about the v axis of the unit. l

6. An ,electric heater comprising a box .having an apertured toppivoted for movement in a vertical plane, said box consisting f GEORGE E. STEVENS.
