HENRY A. ZIOLA, OF TOLEDO, OHIO, ASSIGNOR TO THE SWARTZBAUGH MANUI'AO'IUB- ING COMPANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO.

ELECTRIC TABLE s'rovn Application filed April 23, 1924. Serial No. 708,348.

To all whom it may concern:

Be it known that I, HENRY A. ZIOLA, a citizen of Austria, and a resident of Toledo, in the county of Lucas and State of OhlO, have invented a new and useful Electric Table Stove, which invention is fully set forth in the following specification.

This invention relates to electrical devices and particularly to a table stove of the multiple burner type.

The object of the invention is the provision of a device of the character described, which is simple and inexpensive to manufacture, and which is strong and durable in construction, whereby to enhance the practicability and commercial value thereof.

The invention is fully described in the following specification, and while in its broader aspect it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanylng drawings, in which,

Figure 1 is a plan view of a device embodying the invention. Fig. 2 is a side ele-- vation thereof, with a part in section, on the line 22 in Fig. 1. Fig. 3 is a vertical cross-section on the line 33 in Fig. 2, and Fig. 4 is a perspective view of a portion of the assembled frame parts, with parts broken away.

The hot-plate illustrated is of the twoheater ty e, and has an elongated bottom plate 1 0 sheet metal with a down-turned edge flange 2, and with parallel side edges and rounded end edges.

A reinforcing bar 3 of channelled form is mounted on the top of the bottom plate between its side edges and with its channel preferably opening upward. The bar is secured at its ends to the bottom plate by bolts 4, as hereinafter more fully described.

A spider frame 5, having in the present instance three equi-distantly spaced radial arms and preferably stamped from sheet metal, is mounted over each end portion of the bar 3, being held centrally by the re-' spective bolt 4, and having one arm parallel with the bar and projecting over the same towards its center. Each spider has downwardly turned reinforcing edge flanges 6, which rest at points on the bar 3, and has a down-turned leg portion 7 at the outer end of each arm. The legs .7 of the inwardly projecting arm of each spider projects into the channelled bar 3 and rests on its bottom,

and the other legs rest on the bottom plate 1. A ton e 8 projects from the free end of each leg through the registering opening 9 in the bottom plate 1, and is bendable under the bottom plate to serve to retain the respective spider to the plate. The le s 7, which seat in the channelled bar 3, ave their tongues projected through registering openings in both the bottom portion of the channelled bar and the bottom plate. A thimble or sleeve '10 is disposed between the central portion of each spider 5 and the bottom of the channelled bar 3 in surrounding relation to the associated bolt 4, and serves to rigidly support the central portion of the spider with respect to the bar.

A ring 11, having an outwardly and downwardly extending flange portion, is mounted over each spider 5 in concentric relation thereto and has a supporting leg 12 projecting downwardly from its inner edge over the outer end portion of each arm of the associated spider 5, and inwardly turned at its end to form a foot portion which seats on the spider arm. The free end of each foot portion has a tongue 13 projecting therefrom through a registering opening 14 in the respective spider arm and bent under the arm to retain the ring in position on the spider.

An electrical heating unit is mounted within each ring 11 and rests on the top of the associated spider 5 and on the inturned feet portions of the ring legs 12, the top of the unit being substantially flush with the top of the ring. The unit in its present embodiment comprises a refractory plate 15 of disc form, having a groove 16 in its top in which is disposed the electrical heating element 17, adapted to be connected in any suitable manner to a source of electrical supply. The refractory plate 15 is encased at its sides and bottom, and has a suitable heat insulating casin for its bottom and side edges. Inasmuch as the construction of the unit forms no part of the present invention, a more detailed description of the same will not be given. Each bolt 4 extends centrally through an associated heatin unit and firmly clamps it to the spider an other frame parts.

Two supporting legs 18 for the device are provided at each end thereof, being attached at their upper ends to the inner s1de of the rim portion of the adjacent ring 11 and extending down at theouter side of the bottom plate 1. The lower ends of the legs 18 are braced by bars 19, one of such bars extending from each leg to the adjacent bolt 4: to which it is attached.

A top plate 20 extends across the central part of the bottom plate 1 and channelled bar 3 in vertical spaced relation to the former,and between the two heating units t the flanges 22.

It is evident that the plate 1, channelled bar 3, spiders 5, and ring 12 are secured together by the inter-engaging of tongues with different parts and that the bolts 4 not only secure the heating units in position, but also augment the actlon of the tongues in firmly and rigidly securing the part together, thus enabling the parts to be easily and quickly assembled and at the same time providing a rigid and durable construction.

I wish it understood that by invention is not limited to any specific construction, arran ement, or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,-

1. In a device of the class described, a bottom plate, a pair of transversely spaced heating units, means for spacing said units vertically from said plate, and a reinforcing element extending longitudinally across the upper surface of the bottom plate.

2. In a device of the class described, a frame, a plurality of heating units on said frame in transversely spaced relation, means for spacing said units from a portion of said frame, and a channel bar for spacing elements of the frame from each other, said bar extending from adjacent the center of one unit to the center of another unit.

3. In a device of the class described, a frame including spiders arranged in transversely spaced relation, a heating unit on each spider, and a single member connecting each unit and spider to the remainder of the frame.

4. In a device of the class described, a frame including-spiders arranged in transversely spaced relation, reinforcing means for the frame, said means also serving properly to position the spiders, a heating unit on each spider, and detachable means for sea reinforcing channel on said frame ar ranged to receive and position one of the legs of each spider, a heating unit on each spider, and a single detachable means for securing each heating unit and its respective spider to said channel and frame. I

3.
