Abstract A burner apparatus for forming a finish on a hollow glass article on a production line, such as a glass container. Glass containers having an integrally formed moil portion on the upper end of the container body portion are loaded in sequence on a continuously moving endless conveyor which carries the containers in line through a heating zone. During their transit through the heating zone, the containers pass between a linear row of opposed burners which direct a high intensity row of flame jets accurately against a narrow portion of the container body to first thermally sever the moil portion from the body and to subsequently form a beaded finish on the container. The containers are rotated during their passage through this set of burners at a controlled rate to achieve the desired finish formation. The burner assembly includes top and bottom housings and an intermediate shim plate that define together plural slots connected to a fuel chamber that is in a recess longitudinally of the burner housing. Air and fuel are supplied to the recess chamber for combustion upon exit from said slots.
A burner assembly for establishing a linear row of flame jets comprising an elongate upper housing member having a planar bottom surface termianting at a longitudinally extending front edge, a lower housing member having a planar top surface coextensive with the bottom surface of said upper member and terminating at a longitudinally extending front edge, a shim plate coextensive with said planar surfaces and clampingly secured in face-to-face engagement therebetween, said shim plate having a front edge coextensive with the respective front edges of said upper and lower housing members and a plurality of slots extending rearwardly from the front edge of said plate between said housing members, the planar surface of at least one of said members having an elongate recess extending in parallel rearwardly spaced relationship to the front edge thereof to define an internal passage communicating with the slots in said shim plate, and means for supplying a combustible gas under pressure to said recess.

A burner assembly for establishing a linear row of flame jets comprising an elongate upper housing member having a planar bottom surface termianting at a longitudinally extending front edge, a lower housing member having a planar top surface coextensive with the bottom surface of said upper member and terminating at a longitudinally extending front edge, a shim plate coextensive with said planar surfaces and clampingly secured in face-to-face engagement therebetween, said shim plate having a front edge coextensive with the respective front edges of said upper and lower housing members and a plurality of slots extending rearwardly from the front edge of said plate between said housing members, the planar surface of at least one of said members having an elongate recess extending in parallel rearwardly spaced relationship to the front edge thereof to define an internal passage communicating with the slots in said shim plate, and means for supplying a combustible gas under pressure to said recess.
Claim 3
Dependent Claim
133 words
A burner assembly as defined in claim 1 wherein said lower housing member has a planar bottom surface extending parallel to its planar upper surface, a second shim plate mounted in face-to-face engagement with said bottom surface of said lower member and having a front edge extending parallel to and rearwardly spaced from the front edge of said lower housing member, an elongate base member clampingly secured to the bottom of second shim plate and having a front edge aligned with the front edge of said lower member, means defining an elongate recess in the upper surface of said base member extending parallel to said front edge of said base member in underlying relationship with the front edge of said second shim plate, and means for supplying air under pressure to said recess.
