Abstract: A conduit connection joint is formed to connect a tube and a fitting body in fluid tight relation. The joint is made by axially compressing the tube in a bore in the fitting body so as to cause formation of an outwardly extending tube bead and at least one inwardly extending tube bead. The engagement of the fitting body and the tube may be further strengthened by a retaining ridge. The retaining ridge may be formed in the fitting body to engage the outwardly extending tube bead to further hold the fitting body and tube in engaged relation.

Abstract: A conduit connection joint is formed to connect a tube and a fitting body in fixed fluid tight relation. The joint is made by compressing the tube in a bore in the fitting body so as to cause formation of at least two beads in the tube during the engagement of the tube to the bore wall. A retaining ridge may be formed in the fitting body to further hold the fitting body and tube in engaged relation.

Abstract: A method of assembling a gas supply device within an appliance cabinet is disclosed. The method comprises bending a tube assembly prior to installation in the appliance, attaching a fitting to the first end of the tube, attaching the fitting of the first end of the tube to a burner assembly, attaching a second fitting having a non-circular portion to the second end of the tube, attaching a mounting bracket with a non-circular profile to the non-circular portion of the second fitting in a fixed condition to prevent rotation of the body with respect to the bracket, and mounting the tube assembly in the appliance cabinet.

Abstract: A conduit connection joint is formed to connect a tube (10) and afitting body (12) in fluid tight relation. The joint is made by axially compressing the tube (10) in a bore (14) in the fitting body (12) so as to cause formation of a first bead (52) in a bead formation area. Further axial compression of the tube (10) causes the sequential formation of an additional bead (54) in the bore (14) so as to provide engagement between the tube (10) and the fitting body (12). The engagement of the fitting body (12) and the tube (10) may be further strengthened by axially compressing and radially expanding the beads (52, 54).

Abstract: A tube assembly for a gas range includes a small aluminum manifold block, valve assemblies adapted to regulate flow of gas from the manifold block to the burners, and burner orifices adapted to control flow of gas to the burners. Aluminum valve supply tubes each have a first end staked to an associated outlet of the manifold block and a second end connected to an inlet of an associated one of the valve assemblies. Aluminum burner tubes each have a first end connected to an outlet of an associated one of the valve assemblies and a second end connected to an associated one of the burner orifices. Two or more small manifold blocks can be interconnected by aluminum manifold supply tubes. The manifold supply tube can be easily bent to position the manifold blocks in any desirable position. An igniter assembly includes a pin extending from a stem of the valve assembly and a contactless position sensor.

Abstract: A gas supply assembly having a tube with a first end and a second end. The first end is provided with a burner fitting and the second end is provided with an inlet fitting, the inlet fitting having an inlet fitting shape. The assembly also has a mounting bracket defining a bracket opening for receiving the inlet fitting. The bracket opening has a bracket opening shape complementary to that of the inlet fitting shape so that the mounting bracket and the inlet fitting cooperate to substantially prohibit rotation of the tube. The present invention also provides a method of assembling an appliance incorporating the gas supply assembly, where the gas supply assembly is attached to a burner assembly before these components are introduced into the appliance's cabinet.

Abstract: A gas appliance includes a pair of separate manifolds which each supply gas to two burner assemblies. Each manifold includes a relatively short and straight steel tube having a central section with a generally square-shaped cross-section and end sections with generally circular-shaped cross-sections, and a pair of end plugs closing the end sections to form a sealed interior space. The end plugs and the tube are swaged together at the end sections to form a gas-tight seal. A pair of bolt-through type valves are associated with each of the manifolds to regulate flow of gas from the manifolds to the burner assemblies. The valves have inlets directly secured to the manifolds and outlets connected to the burner assemblies with burner tubes. A pair of light-weight aluminum supply tubes connect a gas inlet with the two manifolds. The supply tubes are preferably secured to the manifolds with bolt-through type adapters located at the longitudinal centers of the manifold tubes and between the two valves.

Abstract: A tube and fitting assembly is made by the method of relatively moving a tube into an internal bore in a fitting with the internal bore extending end-to-end in the fitting, longitudinally compressing the tube to radially expand it into engagement with the wall of the internal bore, internally threading either the tube or the fitting and with the threads being adapted to receive a second member until it is sealed fluid-tight against the tube and there is therefore no need for a fluid-tight seal between the tube and the first fitting.
