    Wilkins Impts. in Ventilating, Heating, and Lighting in Lamps, <§c. inclined or dovetailed form, which when the upper part is to be affixed to the lower are then inserted in the recess previously formed in the lower part 0; the metal of the one is then brought over the dovetails of the other by manipu¬ lation in the lathe, by which the connection of the two portions are securely 5 effected; by this mode of manufacture and the employment of malleable cast iron therein gas burners may be manufactured considerably cheaper than hitherto, and will at the same time be more durable. My next improvement is a mode of preventing any irregularity or oscillation of the flame from a gas burner produced from the too violent and sudden 10 admission of air to the flame; this I effect by modifying and regulating the supply of air, by allowing it to pass in its passage to the flame through nume¬ rous small apertures. Sheet B, Fig. 14, is an elevation partly in section, and Fig. 15 a plan, partly in section, of a perforated disc or plate applied to a gas burner; the disc or plate d is closely perforated with numerous small holes, ✓ 15 through which the air is admitted to the flame, whereby the air becomes very much divided, and after passing the perforations in the disc is not subject to be effected by the motion of the surrounding atmosphere; the disc is made with a rising portion forming the holder or support for the glass chimney. I prefer to make the disc of glass, porcelain, or other similar substance, but do not 20 confine myself to the use of any particular material, so long as the same prin¬ ciple be employed. My next improvement is a mode of preventing that peculiar noise commonly called in the trade “ fizzing,” frequently produced in fish-tail gas burners. I find that this peculiar effect is produced from the gas having a too free and 25 direct passage to the burner. I therefore construct my burner so as to render the passage of the gas more tortuous, and thereby prevent this noise from occurring. I make this description of burners as shewn in Sheet B, Figure 16, which is a sectional elevation ; the lower end of the stem e, through which the gas passes direct to the burner, when made in the usual manner, is in my 30 improved burner plugged and closed up, the gas passing through lateral holes in the sides of the stem, hence to the burner; the pipe or socket into which the stem of the burner is screwed being made of increased diameter, and the stem projects into it, the gas passing up between the two and through the lateral holes in the stem; thus by the tortuous direction the gas takes in passing 35 to the burner the said “fizzing” effect is prevented. Figure 17 represents a modification of the last-described burner, constructed in a similar manner to prevent the “ fizzing,” and likewise provided with a stem mounted vertically upon the top of the burner, which stem carries a circular conical reflector, by which the light from the flame is reflected arouritl.
