ELECTRIC j HEATER.

Specification of Letters Patent.

Patented May 23,1922.

Application led February 1, 1921. Serial No. 441,525.

To all who-m t may concern:

Be it known that I, HENRY KnUnsHnLD, a citizen of the United States, residing at New Viashington, in the county` of, Crawford and State ot hio, have invented .certain new and useful Improvements in Electric Heaters, of which the ,tollowingfis a specification.

This invention relates to electric heaters, and has for its particular object to provide a simple and improved form of heating element, the same comprising a coil which is supported between two bars of insulating material, these bars being mounted on a pair of screw rods which can be adjusted to tension the coil and also to attach the element of a base or the like. Although shown and illustrated .in connection with a stand or upright heater, the element may be used in a horizontal position, or'` on other types of electric heating devices, the main 'feature of novelty comprising the particular structure of the element itself.

ln the accompanying drawings Fig. l, is a side elevation ot the heating resistance element, showing the element applied to a stand heater. the heater being in section. Fig. 2 is a longitudinal section of one ofthe insulating bars. y

Reterringspecilically to the drawings, l indicates the bars between which the heater coil 2 .is `extended in zigzag relation, the coil passing through holes 9 communicating with groove l0 in each bar. After the coil is set in place this groove or channel may be filled with cement to hold the coil in position. The bars are mounted `at their ends on a pair of threaded rods 3 which re ceive nuts 3a between which the bars are clamped, and obviously by adjusting the nuts the bars can be forced away from eachy other to increase or adjust the tension on the coils 2 so as to support the latter in proper position. The terminals of the coils are attached to the ends of the rods 3, where they may be fastened by nuts 3".

Fig. l shows one manner ot use ot' the element for a stand heater or the like, the element being mounted on a base 4L by inserting the ends of the rods 3 through holes in the top of the base and clamping the same by nuts thereunder, the cord terminals ll being attached to the lower ends of the rods. The legs 6 of the base may be provided with lihrefeet 7 for insulation, and a casing l2 may enclose the heating element.

The construction described is very cheap and easily assembled, and provides an element which can be used for various purposes and which can be quickly and easily applied to the articles, examples of such articles being stand heaters, toasters and various other heating appliances familiar to those vac-` quainted with the art.

l claim: i

l. A heating element comprising a pair of bars. a coil extending between the bars, and j spacing rods separating the bars, and adapted to tension the coil, the ends of the rods being extended beyond one ot the bars and serving to rigidly attach the element to a` support. l j

2. An electric heater comprising a support. having holes therein, a pair of bars of insulating material, `a coil extending back and forth between `the bars, and spacing rods extending between the bars, the ends of the rods extending through the holesV and being clamped to the support and provided with means for attachment of cord terminals thereto.

"In testimony whereof, I do aifix my signature in presence of two witnesses.
