Opinion

BENEDICT, District Judge.

This is a suit in equity brought to obtain an injunction, and to recover damages, for an alleged infringement by the defendants of a patent re-issued to Ebenezer Blackman, December 5th, 1876, known as re-issue No. 7,417. The invention is stated in this re-issue to be “a glass base for coal oil burners, so constructed as to fit on a lamp or burner, in a manner similar to ordinary glass chimneys, ■ and having a laterally projecting flange or rim, to support a chimney or reflector; also, in the combination of said base with a coal oil burner; and, also, the combination of said base with a burner and a chimney or reflector, as hereinafter more fully explained.” Accompanying this description are drawings showing the base of a lamp chimney from various points of view. The inventor disclaims a chimney base incapable of transmitting light through it, and without such a tubular body as is required to support it on a coal oil lamp and to direct the current of air to the flame. Of the six claims in this re-issue, only the 1st, 2d, 4th and 5th need be mentioned here, those being the claims alleged to have been infringed by the defendants. The first claim is as follows: “A glass base for coal oil burners, constructed with a tubular body to fit around the cone or burner, and having a laterally projecting flange, substantially as and for the purpose set forth.” The second claim is as follows: “A glass base having the contraction, I, and the laterally projecting flange h, substantially as described.” The fourth claim is as follows: “A transparent base for a coal oil lamp chimney, having a tubular body of suitable form and length to fit and support it on the lamp, and having a laterally projecting flange, h, substantially as described.” The fifth claim is as follows: “The combination of a transparent base, having a tubular body, B, of suitable form and length to adapt it to be used on a coal oil lamp, and a laterally projecting flange, h, with a chimney, substantially as described.” In regard to these claims it is to be observed, that the first, second and fourth are each for a contrivance variously styled a “glass base for coal oil burners,” a “glass base” and a [541]*541“transparent base for a coal oil lamp chimney,'’ but more properly styled a chimney base, capable of use only when forming a part of a lamp chimney. The fifth claim is for a combination consisting of two elements —one, a chimney base, as described, the other, a chimney top of any form.

The first question presented is, whether these claims are for the same invention described in the original patent; for, if not, they are void and afford no cause of action to the plaintiffs. An examination of the terms of the original patent, therefore, becomes necessary. The original patent was issued to Ebenezer Blackman, February 6th, 18G2 [1S72],2 and is known as original patent No. 123,325. The specification of that patent gives, first, a description of what is styled the “chimney proper,” elsewhere styled by the inventor “the body of the chimney,” and by his counsel, on this argument, the “top piece,” but what would be accurately styled a “chimney top.” This chimney proper, top piece or chimney top is described as constructed of two sheets of mica whose vertical edges are united by a metal strip, and then bent so as to form a tube, and having at the bottom projections, whereby, as the patent states, “to fasten the mica chimney (top) securely to the glass base.” Next follows a description of the chimney base, “that is to say, its upper portion is made of a suitable size and form to fit the chimney (top) and its lower portion to fit the lamp, and between the upper and lower portion it is contracted by an external groove, the upper portion flaring or inclined outward.” Then follows this significant statement: “In use, the chimney and base are intended to remain united, the whole being put on or taken off together.” Two claims follow: “First. A lamp chimney, consisting of sheets of mica united by means of the double and indented or perforated metal strips, b, and provided with means for attaching it to the base, B, substantially as described. Second. A glass base, B, having the contraction, I, and the flaring top, h, constructed and arranged to operate substantially as set forth.” It will be observed, from this statement in regard to the original patent, that the thing described in the original specification is a contrivance adapted to produce a draft of air around the flame of a lamp; in other words, a lamp chimney. This contrivance is described by describing first its top and then its base, accompanying the description of the two parts with the statement, that these parts are to remain united, and so form a compound unit, which is the subject of the patent. The subject-matter of the original patent is the contrivance, as a whole, described as, and being in fact, a lamp chimney; or a combination, the elements of which are the glass chimney base and the mica chimney top therein described. Were it not for the express statement in the original specification to which allusion has been made, and to wliieh the second claim makes special reference, it might, perhaps, be, that the cbimBey base described could be considered a separate device, or a distinct sub-combination of devices, and so capable of being the subject of a separate claim. But, the specific statement of the patent, that, in use, the ba^se and top are to remain united, the whole being put on or taken off together, forbids the conclusion that the inventor ever conceived the idea of his chimney base as a separate and distinct device. In his mind, the chimney base had no existence except as firmly attached to his mica top, and forming an inseparable part of a mica top lamp chimney. The statement in the specification, therefore, compels a determination that the language used was not intended to suggest, and cannot be held substantially to indicate, that the chimney base is a severable part of the contrivance invented. If to the original specification had been attached a claim for the chimney base, as a distinct invention, capable of use by itself, such a claim obviously would have presented a direct conflict with the statement of the specification, that, in use, the base was to remain united with the mica top. This case, therefore, is not within the rule permitting an inventor to select from the elements of a combination, or from the parts of a machine, described in his specification, a severable and distinct device or sub-combination, capable of use by itself, and substantially indicated in his description, and, by means of a surrender and reissue, secure an exclusive right to such single device; because, this inventor, in his original specification, has been careful to state that the chimney base he describes is not to be used except as united to his mica chimney top, and as an inseparable part of his mica top chimney. I, therefore, understand the subject-matter of the original patent to be either the mica top lamp chimney therein described, or a combination whose elements are the devices employed in the chimney described for the purposes designated. This understanding is not at variance with the claims of the original patent, for, in legal effect, the statement of the specification already alluded to is part of each claim. So far as the second claim is concerned, an intention to have it considered a part of the claim is manifest, for, the claim states, not only that the base is to be constructed as described, but, also, “arranged to operate substantially as set forth,” that is to say, always firmly united to the mica top.
