Heating element assembly

Claim 2

A brace for interlocking a group of elongated heating elements each having two legs arranged substantially parallel to one another and joined by a U-shaped bend at one end of the element, said legs being fixed to a supporting wall at the remaining end of the element, the brace comprising: a partition having oppositely facing outer edges each having a plurality of recesses formed across them complementary to the spacing of the element legs for loosely engaging an equal number of element legs along each of its outer edges while perpendicular to the heating element legs, said partition being free to move parallel to the element legs in response to their vibration to an average vibrational node for the plurality of elements.

Claim 3

The brace of claim 1 wherein the partition comprises a pair of parallel walls having said recesses formed across spaced outer edges at opposite sides of the partition.

Claim 4

The brace of claim 1 wherein each of said outer edges are formed across a pair of spaced walls.

Claim 5

The brace of claim 3 wherein the spaced walls of the partition are individually made from light sheet materials.

Claim 6

The combination of: an immersion-type liqud heater having a plurality of elongated heating elements each having a pair of legs bent in an elongated U-shaped configuration at one end of the element, and with open ends at the remaining end of the element supported in a plug wall; and a brace for loosely interlocking the heating elements, said brace comprising: a unitary partition having oppositely facing outer edges with a plurality of recesses formed across them complementary to the spacing of the element legs for loosely engaging an equal number of element legs along each of its outer edges; said partition being movably mounted perpendicularly between the legs of each element in loose engagement with the legs for dampening vibration in the elements by moving freely along the element legs to an average vibrational node for the plurality of elements.

Claim 7

The combination of: an immersion-type liqud heater having a plurality of elongated heating elements each having a pair of legs bent in an elongated U-shaped configuration at one end of the element, and with open ends at the remaining end of the element supported in a plug wall; and a brace for loosely interlocking the heating elements, said brace comprising: a unitary partition having oppositely facing outer edges with a plurality of recesses formed across them complementary to the spacing of the element legs for loosely engaging an equal number of element legs along each of its outer edges; said partition being movably mounted perpendicularly between the legs of each element in loose engagement with the legs for dampening vibration in the elements by moving freely along the element legs to an average vibrational node for the plurality of elements.

Claim 8

The apparatus of claim 5, wherein the partition outer edges are each formed across spaced parallel plates.

Claim 9

The apparatus of claim 1 wherein there are three heating elements and three recesses formed across each outer edge of the partition.

Claim 10

The apparatus of claim 1 wherein there are three heating elements and three recesses formed across each outer edge of the partition; each heating element being arranged along the partition with its legs straddling the outer edges in substantially parallel positions.

Claim 11

The apparatus of claim 1 wherein there are three heating elements and three recesses formed across each outer edge of the partition; each heating element being arranged along the partition with its legs straddling the outer edges in substantially parallel positions; the separation of the bases of corresponding recesses between the outer edges of the partition being slightly greater than the separation between the legs of each heating element at their respective ends.

Claim 12

An extended-life heating element assembly of the type including electrical resistance heating elements extending from a supporting wall end wherein the heating elements each comprise two substantially parallel legs joined by a U-shaped bend at one end of the element and by two open ends at its opposite end, comprising: a tapered outer surface area formed along the open ends of each element; complementary tapered apertures formed through the end wall in engagement with the tapered outer surface areas of the elements; a partition having a pair of oppositely facing outer edges each having a plurality of recesses formed across them complementary to the spacing of the element legs for loosely engaging an equal number of heating element legs along each of its outer edges while perpendicular to the heating element legs, said partition being free to move parallel to them in response to their vibration to an average vibrational node for the plurality of elements.

Claim 13

An extended-life heating element assembly of the type including electrical resistance heating elements extending from a supporting wall end wherein the heating elements each comprise two substantially parallel legs joined by a U-shaped bend at one end of the element and by two open ends at its opposite end, comprising: a tapered outer surface area formed along the open ends of each element; complementary tapered apertures formed through the end wall in engagement with the tapered outer surface areas of the elements; a partition having a pair of oppositely facing outer edges each having a plurality of recesses formed across them complementary to the spacing of the element legs for loosely engaging an equal number of heating element legs along each of its outer edges while perpendicular to the heating element legs, said partition being free to move parallel to them in response to their vibration to an average vibrational node for the plurality of elements.
