 SCHNEIDER V. LOVELL. 667 �ment in shcade-holders for lamps;" the original patent, No, 182,973, having been granted to Cari Votti, as inventer, October 3, 1876. The specification of the reissue says : �"My invention relates to lamps, and it consists in a transparent sliade- holder, or holder of a material allowing the passage of light and shade, or globe, so aiinexed that an ordinary lamp-burner can be used without a chim- ney, as will be hereinafter more fully set forth. In the annexed drawing, figure 1 is a v.ertical section of my invention. Figure 2 is.a plan view of the shade-holder. A represents an ordinary lamp-burner, provided with a cir- cumferential flange, a, for the support of the cone, 6, and which, ordinarily, also serves to support the chimney or cylinder. This flange is provided with suitable perforations, through which air is admitted both inside and outside of the cone. Instead of using the flange, a, for the support of the ordinary chimney, I place on the same my shade-holder, 6, which is made of glass or other suitable transparent material, or material that will allow of the passage of light and which is provided with a tubular extension or sooket, c, that fits over the cone, 6,- leaving an air space between its inner surface and the outer surface of said cone. From said socket extends a broad dish-shaped flange, d, which is provided with a rim, e, and which serves to support and retain the shade, 0. The flange, d, is perfectly closed, so that no air will pass to the flame exeept what is admitted through the perforations in the burner-flange, a, and by these means I am enabled to produce a bright flame without the use of an ordinary chimney or cylinder. The advautage of this arrangement will be apparent, since it allows of keeping the burner clean, and of trimming the wick without difflculty, and the annoyance of broken chimneys is avoided. It will be seen that with the shade-holder and shade annexed, as shown and de- scribed, the ordinary burner will perform the required functions without the use of a chimney. I am well aware that transparent shade-holders are of themselves not new ; hence 1 do not claim such, broadly, as being my inven- tion." �The claims of the reissxie are as follows : �"(1) In alamp having a burner, the combination of a shade-holder made of material that will admit of the passage of light, and a shade or globe arranged and constructed substantially as described, whereby the burner performs the required functions without the use of a chimney, as set forth. (2) The shade- holder, B, constructed of material that will admit of the passage of light, and provided with a downwardly-extending socket, c, and dish-shaped flange, d, with rim, e, in combination with a globe or shade, C, and burner, A, of alamp, as and for the purposes herein set forth. (3) The combination in alamp of the burner. A, having perforated flange, a, and cone, 6, the shade-holder, B, with central socket, e, and a shado or globe, C, substantially as and for the purposes herein set forth," �One of the defenecs set up in the answer is that, in the specifica- tion of the reissue, there is not given, as required by the statute, a description of the invention, and of the process of maldng, construct- ��� �
