Abstract
Abstract A heating assembly of the type wherein a plurality of metal sheathed electric heating elements are arranged in a cluster, each having one end connected to a flange member, the elements being elongated and cantileverly extending from the flange member, and means for holding end portions of said heating elements in predetermined laterally spaced relation, comprising a sheet metal band for each heating element having sockets for receiving and holding the end portions, the sheet metal bands being connnected together. In a preferred form, the sheet metal band is of rectilinear formation with socket portions formed at the four corners to receive respective ends of the legs of a heating element. The sheet metal bands are connected to each other so that their socket portions hold the pairs of legs of all elements in spaced relation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
In an electric heater of the type wherein a plurality of metal sheathed tubular elements of double loop formation of the character described each has the ends of a pair of legs connected to a flange member and with the legs cantileverly extending therefrom in side-by-side relation, the improvement comprising means for holding the pairs of legs of one element in lateral spaced relation with respect to each other and with respect to the pairs of legs of the other elements, comprising a sheet metal member for each heating element, each sheet metal member being in the form of a closed band of rectangular formation with socket portions formed in the four corners for receiving respective ones of the legs of one heating element and holding the same in spaced relation, said sheet metal members being connected to each other so tHat their socket portions hold the pairs of legs of all elements in spaced relation.
Claim 2
Dependent Claim
156 words
In an electric heater of the type wherein a plurality of metal sheathed tubular elements of double loop formation of the character described each has the ends of a pair of legs connected to a flange member and with the legs cantileverly extending therefrom in side-by-side relation, the improvement comprising means for holding the pairs of legs of one element in lateral spaced relation with respect to each other and with respect to the pairs of legs of the other elements, comprising a sheet metal member for each heating element, each sheet metal member being in the form of a closed band of rectangular formation with socket portions formed in the four corners for receiving respective ones of the legs of one heating element and holding the same in spaced relation, said sheet metal members being connected to each other so tHat their socket portions hold the pairs of legs of all elements in spaced relation.
Claim 3
Dependent Claim
21 words
The construction of claim 1 wherein a corner of one sheet metal member is connected to a corner of another member.
Claim 4
Dependent Claim
33 words
The construction of claim 1 wherein a flat side of at least one sheet metal member is deformed inwardly to tighten the grip of said member on the legs in its socket portions.
Claim 5
Dependent Claim
175 words
In an electric heater of the type wherein a cluster of metal sheathed tubular elements of double loop formation of the character described each has the ends of a pair of legs connected to a flange member and with the legs cantileverly extending therefrom in side-by-side relation, and wherein one element is at the center and the other elements are grouped thereabout, the improvement comprising means for holding the pairs of legs of one element in laterally spaced relation with respect to each other and with respect to the pairs of legs of the other elements, comprising a sheet metal member for each heating element, each sheet metal member having socket portions for receiving respective ones of the pair of legs of one heating element and holding the same in spaced relation, a metal ring-like member encompassing the sheet metal member for the center tubular element and secured thereto, and the sheet metal members for the tubular elements grouped about said center element being connected to said ring-like member at spaced points along its periphery.
Claim 6
Dependent Claim
175 words
In an electric heater of the type wherein a cluster of metal sheathed tubular elements of double loop formation of the character described each has the ends of a pair of legs connected to a flange member and with the legs cantileverly extending therefrom in side-by-side relation, and wherein one element is at the center and the other elements are grouped thereabout, the improvement comprising means for holding the pairs of legs of one element in laterally spaced relation with respect to each other and with respect to the pairs of legs of the other elements, comprising a sheet metal member for each heating element, each sheet metal member having socket portions for receiving respective ones of the pair of legs of one heating element and holding the same in spaced relation, a metal ring-like member encompassing the sheet metal member for the center tubular element and secured thereto, and the sheet metal members for the tubular elements grouped about said center element being connected to said ring-like member at spaced points along its periphery.
