Hot plate for cooking

Claim 2

A hot plate comprising a hub from which spokes radially extend in a horizontal plane, the spokes being formed by refractory fibrous or woven flat strips each positioned in a vertical plane and having upper edges in which downwardly extending notches are formed, and molybdenum disilicide wire in the form of a flat, spiral having convolutions with portions inserted in the notches, the wire having terminating ends, and means for connecting the ends with electric current.

Claim 3

The hot plate of claim 1 in which said strips have lower edges, and there is a flat plate on which the lower edges rest, said strips being stiff so as to support said convolutions but soft enough to absorb the transmission of mechanical shock from the plate to the convolutions.

Claim 4

The hot plate of claim 2 in which said notches are in the form of slits extending downwardly from said upper edges to openings in said strips and which are horizontally elongated and in which said portions of said convolutions are positioned.

Claim 5

The hot plate of claim 3 in which said strips are soft enough to permit said convolution portions to be pushed downwardly through said slits and into said openings during assembly of the hot plate.

Claim 6

The hot plate of claim 2 in which said flat plate is formed by refractory fibrous material.

Claim 7

A hot plate comprising a hub from which spokes radially extend in a horizontal plane, the spokes being formed by refractory fibrous or woven flat strips each positioned in a vertical plane and having upper edges in which downwardly extending notches are formed, and molybdenum disilicide wire in the form of a flat spiral having convolutions with portions inserted in the notches, the wire having terminating ends, and means for connecting the ends with electric current; said strips having lower edges, and there is a flat plate on which the lower edges rest, said strips being stiff so as to support said convolutions but soft enough to absorb the transmission of mechanical shock from the plate to the convolutions; said notches being in the form of slits extending downwardly from said upper edges to openings in said strips and which are horizontally elongated and in which said portions of said convolutions are positioned; said strips being soft enough to permit said convolution portions to be pushed downwardly through said slits and into said openings during assembly of the hot plate said strips having radially inner ends and said hug having vertical slots in which the inner ends are positioned.

Claim 8

A hot plate comprising a hub from which spokes radially extend in a horizontal plane, the spokes being formed by refractory fibrous or woven flat strips each positioned in a vertical plane and having upper edges in which downwardly extending notches are formed, and molybdenum disilicide wire in the form of a flat spiral having convolutions with portions inserted in the notches, the wire having terminating ends, and means for connecting the ends with electric current; said strips having lower edges, and there is a flat plate on which the lower edges rest, said strips being stiff so as to support said convolutions but soft enough to absorb the transmission of mechanical shock from the plate to the convolutions; said notches being in the form of slits extending downwardly from said upper edges to openings in said strips and which are horizontally elongated and in which said portions of said convolutions are positioned; said strips being soft enough to permit said convolution portions to be pushed downwardly through said slits and into said openings during assembly of the hot plate said strips having radially inner ends and said hug having vertical slots in which the inner ends are positioned.

Claim 9

The hot plate of claim 6 in which each two of said spokes is formed by a single length of said strip having outer ends joined together circumferentially by an arcuate section of the strip.

Claim 10

A hot plate comprising a hub from which spokes radially extend in a horizontal plane, the spokes being formed by refractory fibrous or woven flat strips each positioned in a vertical plane and having upper edges in which downwardly extending notches are formed, and molybdenum disilicide wire in the form of a flat spiral having convolutions with portions inserted in the notches, the wire having terminating ends, and means for connecting the ends with electric current; said strips having lower edges, and there is a flat place on which the lower edges rest, said strips being stiff so as to support said convolutions but soft enough to absorb the transmission of mechanical shock from the plate to the convolutions; said flat plate being formed by refractory fibrous material; said strips having radially outer ends and a sheet metal cup has a side wall encircling and enclosing the outer ends; said flat plate and the cup having flat interengaging surfaces, and a cylinder of refractory material being interposed between and contacted by the strips outer ends and the cup's side wall.

Claim 11

A hot plate comprising a hub from which spokes radially extend in a horizontal plane, the spokes being formed by refractory fibrous or woven flat strips each positioned in a vertical plane and having upper edges in which downwardly extending notches are formed, and molybdenum disilicide wire in the form of a flat spiral having convolutions with portions inserted in the notches, the wire having terminating ends, and means for connecting the ends with electric current; said strips having lower edges, and there is a flat place on which the lower edges rest, said strips being stiff so as to support said convolutions but soft enough to absorb the transmission of mechanical shock from the plate to the convolutions; said flat plate being formed by refractory fibrous material; said strips having radially outer ends and a sheet metal cup has a side wall encircling and enclosing the outer ends; said flat plate and the cup having flat interengaging surfaces, and a cylinder of refractory material being interposed between and contacted by the strips outer ends and the cup's side wall.

Claim 12

The hot plate of claim 8 in which said cup has a rim and the rim and the upper edges of said strips are covered by a glass plate.

Claim 13

The hot plate of claim 9 in which said rim has releasably connnected brackets adhesively fixed to the glass plate so as to solely thereby support the hot plate.

Claim 14

The hot plate of claim 8 in which said flat plate has a recess formed upwardly in its bottom and said terminating ends extend downwardly through the flat plate and into the recess and connected to flexible wires stranded from fine wire, the flexible wire extending through said cylinder of refractory material and the cup's said side wall to a terminal block fixed to the outside of the side wall and having terminal screws for connection to a power line, said flexible wires having terminating ends electrically connected to the terminal screws.
