RECUPERATIVE GAS-RETORT SETTING- SPECIFICATION forming part of Letters Patent No. 767,333, dated August 9, 1904.

Application iled October 22, 1901. Serial No. 79,533. (No model.)

T0 @ZZ wtmn it mln/y 0071/067711:

Be it known that we, EDWARD H. EARN- sHAw and WTILLIAM H. GARTLEY, citizens of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have jointly invented certain new and useful Improvements in Apparatus for Making' Gas, of which the following is a specification.

The invention relates to improvements in that class of gas apparatus in which use is made of retorts and of recuperator means for b heating them; and the principal object of the invention is to provide for independently controlling the temperature to which the retorts are heated at different portions or sections of their lengths.

To this and other ends hereinafter set forth the invention, stated in general terms, comprises the combination, with a bench of retorts and its secondary air-supply, of means for introducing' more or less air in this secondary air-supply at different sections throughout the lengths of the retorts.

The invention further comprises the `improvements hereinafter described and claimed.

The nature, characteristic features, and scope of our invention will be more fully understood from the follow-ing' description, taken in connection with the accompanying drawings, forming part hereof, in which- Figure l is a perspective view, principally in section, illustrating portions of a gas-retort apparatus embodying features of the invention. Fig. 2 is a view showing at the lefthand side thereofafront elevation and at the right-hand side a sectional view of apparatus embodying features of the invention, -and Fig. 3 is a sectional View taken on the line 3 3 of Fig. 2 on an enlarged scale.

In the drawings, Fig. 2, 1 represents the retorts.

2 represents the passages for feeding gas which is burned by the secondary air-supply at 3 in order to heat the retorts. rIhe products of this combustion traverse the fiues 4.

are horizontal, as is shown in Fig. -1 and also in Fig. 2. The passages 6 for the incoming secondary air-supply are arranged side by side, as shown in Fig. l, and vertically. The arrows in that figure marked 8" show the path of the products of combustion and the arrows marked 9 show the path of the secondary air-supply in one of the passages, of which there are shown six, althoughthe number is not material nor is the construction and arrangement of details of the flues and passages. The intake for the supply of secondary air is subdivided, each portion of it provided with a door or other means for regulating the passage of air through it. Each subdivision extends to a set of passages 6. As shown in the drawings, there are two subdivisions l() and ll. The subdivision l0 is arranged-to supply air to the three separate vertical passages 6, which are located nearest the front of the apparatus, and the subdivision ll is arranged to supply the group of three passages 6. near the back of the apparatus. Of course the number of subdivisions, as well as the number of passages connected therewith, may be increased or diminished.

The mode of operation of the described improvement may be explained as follows: The apparatus as a whole is operated in the ordinary way, with lthe exception that the doors, as 13 and 14:, which control the intake to the secondary air supply, are so opened and closed as to control the degree of heating of the various portions of the retorts throughout their lengths, and in this way the operation of the apparatus as a whole is materially improved. For example, it frequently happens that the retorts are not charged evenly throughout their lengths, and by the present invention this may be corrected by the application oi' the proper degree of heat in proportion to the extent ot' the charging throughout the length ot' the retorts.

It will be obvious to those skilled in the art to which our invention appertains -that modifications may be made in detail without departing from the spirit thereof. Hence we do not limit our invention to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

Having thus described the nature and objects ot' our invention, what we claim as new, and desire to secure by Letters Patent, is# l. A recuperative gas-retort setting provided with retorts, a gas-furnace having gasoutlets arranged beneath the retorts, eductionlues for carrying off the products of combustion, separate systems of induction-fines surrounding` the eduction-liues and heated thereby and arranged to separately discharge in proximity with said gas-outlets, and means at the points oi' admission for controlling the intake of air to each system of inductionflues thereby providing independent secondary air-supplies for dilerent portions of the setting throughout its length, substantially as described.

2. A recuperative gas-retort setting' provided with retorts, a gas-furnace having gasoutlets arranged in rows beneath the retorts, ed uction-liues for carrying oli' the products of combustion, separate systems of inductioniiues surrounding the eduction-flues and heated thereby and having separate groups of discharge-orifices arranged in proximity with said gas-outlets, and means at the points ot' admission for controlling the intake of air to each system ot' induction-lines thereby providing independent secondary air-supplies for dierent portions of the setting throughout its length, substantially as described.

In testimony whereof we have hereunto signed our names.
