Abstract: 1371629 Burner for glass working OWENSILLINOIS Inc 1 Oct 1971 [2 Oct 1970] 7320/74 Divided out of 1371627 Heading F4T A burner assembly for a linear row of flame jets in glass container manufacture for removal of the waste, moil, portion, comprises upper and lower members with coextensive bottom and top surfaces respectively, a shim plate, coextensive with and clamped between the upper and lower members so that the joint edges are in alignment, having a plurality of slots extending rearwardly substantially at right angles to the front edge, the surface of one at least of the members having an elongate recess in parallel rearwardly spaced relation to the front edge to give an internal passage communicating with the shim slots and means for supplying a combustible gas under pressure to the recess. Burner mounting, Figs. 15, 16, 17.-Pre-heat burners (70) Fig. 11 (not shown) comprise spaced opposed pipes (270) on opposite sides of the join of moil M to container C and are provided with a plurality of bores (274) forming nozzles through which combustible gas under pressure is expelled to give rows of flame jets. Main burner 74 comprises a series of paired modules 282a, 282b each carrying a burner unit 304 mounted on T- shaped brackets 302, the modules 282a, 282b being mounted for independent horizontal, vertical and pivotal adjustment relative to the machine frame F. Each module 282a, 282b includes a frame member 284 with end housings 286 slidable on fixed tubular members 290 and horizontally adjustable by jacks 292. Each end housings 286 is fixed to a post 294 which carries a sleeve 296 and bracket 298, the brackets 298 of the series of modules pivotally carrying an elongate pipe 300 to which the T-shaped brackets 302 are welded. Vertical adjustment of brackets 298 is by jacks 318 and pivotal movement of pipe 300 with brackets 302 is by means of a clamp 320 on pipe 300 with a crank arm 326 secured by a pin-and-slot connection 324 to a jack 322 mounted on frame member 284. Burner construction, Fig. 13.-Burner unit 304 comprises an upper housing member 330 with a longitudinally extending recess 334, in the flat bottom surface 332, terminating just short of each end of member 330, the recess 334 being connected by fuel passages 340, 336 and screw threaded section 342 to a supply conduit fitting through which combustible gas or air/gas mixture can be fed. A shim plate 344 abuts surface 332 and is formed with parallel slots 346 extending rearwardly from front edge 348 to interconnect with recess 334, a plate 350 below shim 344 with recess 352 completing the combustion chamber with outlet slots 346. Below plate 350, a second shim plate 354 of reduced width and a lower housing member 358 with recess 360 form a chamber with a continuous slot 370 through which air under pressure is supplied through passages 364, 362 and screw-threaded section 366 connected to an air supply. The various plates are clamped together as by screws 368 to allow replacement of the shim plates. During the moil severing operation, when a narrow flame is required the shim plate 344 will be thin, but a thicker shim plate will be used for edge finishing. Shims 344 may also have differing slot dimensions or spacings. Specifications 1,371,627, 1,371,628 and 1,371,630 are referred to.
