Abstract: 18,510. Smith, W. Aug. 22. Vapour Lamps; globe and reflector holders.-A two-burner incandescent hydrocarbon-vapour lamp is shown in Figs. 1 and 2, a globe and reflector holder for use with the lamp is shown in Fig. 5, and a modified single-burner lamp is shown in Fig. 3. In the arrangement shown in Figs. 1 and 2, a vaporizer 14 is disposed between the mantles 8 of two burners 2<b> on branches 2<a> of a main burner body consisting of two sections 1, 2 shouldered together, and the vapour passes out through a pipe 17 to a superheater 24 carried by an auxiliary burner body consisting of two sections 20, 23 screw-threaded together. The superheater is disposed under a stepped vapour nipple 30, which is provided with a clearing-needle 59, and is located under an adjustable air-tube 18 arranged under a deflector 2<c> in a mixing-chamber 3 of the main burner body. The vaporizer and superheater are respectively heated by bunsen burners 47, 48 provided with pilot burners 49, 50. The vaporizer 14 comprises inner and outer tubes 13, 9 disposed over a central boss 2<d> on the section 2. The tube 9 is closed at the top by a screw plug or cap 10, and is provided at the bottom with a terminal consisting of a threaded part 11<a> and a wrench-nut 11, formed with a projection 11<b> for attachment in a socket 2<f> in the boss 2<d> by a set-screw 12. The terminal is also formed with an oil or fuel duct 11<c> connected with a supply pipe 16, a vapour duct 11<d> connected with the pipe 17, and a screw socket 11<e> for the vapour tube 13. A gauze filter 15 surrounds the open upper end of the tube 13. The superheater 24 is constructed with a tube secured at the upper end in a hub 20<c> of the section 20, and closed at the lower end by a terminal consisting of a threaded part 25 with a vapour duct 25<a>, a wrench nut 26 with a vapour duct 26<a> and a flared seat 26<b>, and a part 27 closed by a screw plug 29 and fitted with a tapered cylindrical head 28, which is formed with a vapour duct 28<a> connected with the pipe 17, takes into the seat 26<b>, and is formed with a concavity 28<c> for the end of the plug 29. The nipple 30 is fitted into an extension 20<d> of the hub 20<c>, is threaded int) the tube 24 against an annular shoulder 20<b> of the section 20, and has an extension 30<a> above the part 20<d> and a cup deflector 21 supported on an external annular shoulder 20<a> of the section 20. A filling 31 of coiled wire gauze surrounds the duct 25<a>, and supports a gauze filtering-disc 32. The ontlet of the nipple 30 beneath its upper step is provided with a gauze guard-disc 33. The main and auxiliary burner bodies are connected by a pillar 35, and also by gas tubes or "bleeders" 19. The bleeders are connected to the body sections during the casting of the latter, their ends being tinned and inserted in core prints in the sand. They extend into a heating-chamber 22 in the section 20. The section 23 is provided with an annular flange 23<a> forming a central air passage 23<b>, and a seat 23<c> for a conical gauze screen 34. The burners 47, 48 are connected, respectively, with a gas nipple 45 and a tube 46 controlled by a two-way plug cock 42, fitted in a valve casing 41 formed in a coupling 37 connecting an ordinary pendent gas pipe 36 to the main burner body. The mantles 8 are suspended on hooked rods 6 adjustable in posts 5 by screws 7. The needle 59 is secured by a set-screw 60 to a curved arm 58 of a needle-bar 56, which is also provided with a handle 57, and is mounted in a sleeve 55 supported between clamp jaws 52, 53 on a bracket 51 on the main burner body. The sleeve 55 is provided with a stepped slot 55<a>, formed with a seat 55<b> for the arm 58, and with an open part and a blind part. The globe 11, Fig. 5, is retained by thumb-screws 12 on a ring 10 secured by nuts 14 on slide rods 13, which pass through tubes 5, 6 provided with guide nuts or collars 7, 8, and carried by a bracket 3 adjustable on the gas pipe 1. The rods 13 are fitted with loose collars 16 and pivoted catches 15. A reflector 20 is secured on the pipe 1 by means of a nut 23 and washers 21, 22. The lamp shown in Fig. 3 is suitable for large mantles. The upper section 20<1> of an auxiliary burner body is formed integral with a bridge 35'. The lower section 23<1> is formed with an annular chamber 23<11> having perforations in its inner wall and connected at the outer wall to a lower bunsen burner 48<1>. The superheater terminal comprises an upper part 25 with a vapour duct 25<a>, a lower wrench nut 26<1> with a rightangled vapour duct 26<a>, and a horizontal screw plug 29<1> with a vapour duct 29<11> and a connection with the vapour pipe 17<1>. The gas-pipe coupling 37<1> is formed on the bridge 35', and is closed at the lower end by a screw plug 37<11>. A pendent rod 61 is screwed into the bridge 35', and is provided with a threaded lower end 61<a>, a flange 61<b>, and a nut 62 for retaining a slotted globe ring 63. According to the Provisional Specification, the vaporizer may be started by providing a cup containing asbestos for receiving benzene or other spirit.
