25 The Celebrated 6-Way Star Improved Gas Dissolver, with 2-Bye Passes. The Best Dissolver Made- This improved Gas Dissolver, saving 50 per cent, of Oxygen, and producing a more EQUAL and PERFECT dissolving effect than any previously made. This useful piece of apparatus consists of a Single plug, which is so arranged as to cut off and turn on the Gas to the four stop-cocks of a pair of Lanterns, and can be applied equally well to the Mixed Gas Oxyhydrogen Light, or the safety blow-through Jet. In order to keep alight the Hydrogen in each Lantern a small stop-cock is pro- vided, these can be adjusted at the commencement of the exhibition, so as to allow a larger or smaller quantity to be burning, according to circumstances. When the Lever is quite upright, as in the sketch, both Lanterns have their full supply of Gas, and are illuminated for the pro- duction of Lightning, the Aurora Borealis, Bursting Bombs, and other flashing effects. When the Lever is to the right, the right hand Lantern (or upper one, if a Bi-unial or Perpendicular Lantern) is on, and now if the Lever is slowly moved over to the left, the dissolving effect is brought about in the mosl perfect manner At the starting of the Lever, the light in the Lantern then does not drop, and suffer from the loss of Hydrogen, as in all other Gas Dissolvers. From the simplicity of the parts, the plug ean be taken out and cleaned when necessary. Price 12s. 6d. each. Cheaper than any other house in the trade. Ditto, with 4-way taps, 10/6.
