CHARLES W. SIEMENS, OF WES'IMINSTER, COUNTY OF MIDDLESEX, ENGLAND.
ROTAIiIVEA REG ENERATIVE FURNACE.
SPECIFICATION forming part of Letters Patent No. 244,492, dated J'uly 19, 1881.
Application filed December 9, 1879.
To all whom it may concern:
. Be it known that I, CHARLES W. SIEMENS,
of Westminster, county ofMiddlesex, En gland, e .have invented an Improvement in Rotative Regenerative Furnaces.
The following description, taken in connection with the accompanying plate of drawings, hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of theinvention, by which the saine may be distinguished from others of a similar class, together with such parts thereof as are claimed as new and are desired to be secured by Letters Patent of the United States.
For many' years three classes of rotary machines for puddling and meltin giron have been known. In one class of machines of this character a cylindrical or partially spherical vessel is rotated on a horizontal axis in another class a basin is made to revolve-in a horizontal plane, and in still another class the sole or hearth of the furnace revolveson an inclined axis. The English patent of Maudsly, No. 1,436, dated June 5, 1858, the subject-matter of which is now public property in this country, shows a furnace constructed in such a manner that motive power may be imparted to the bed thereof for the purpose of causing it to rotate in either a horizontal or inclined plane. Although the. bed of the furnace described in said English patent may be made to revolve in a horizontal plane, the axis of revolution is placed, by preference, about ten degrees out of the perpendicular, so that one side' of the bed will be lower than the other. The furnace described in said English patent has also a lower A 169,033, dated October 19, 1875, a convertingfurnace having a system of regenerators and flues arranged as described in United States patent to C. W. Siemens is provided with an inclined and removable hearth. In this furnace the gas and air enter at one end of the hearth and they products of combustion pass oif at the opposite end. (See, also, the patent of August Ponsard, in which substantially similar modifications of the Siemens furnace are shown.)
In the accompanying plates of drawings, in which corresponding parts are designated by the same letters, Figure l is a longitudinal vertical section of a furnace having a fixed chamber with a revolving bottom or pan, taken on thelineA/B,Fig. 2. Fig.2denotes a transverse vertical section of the same, taken on the line C D of Fig. 1. Fig. 3 is a longitudinal vertical section of a furnace having an inclined fixed chamber with a bottom or pan capable of revolving in an inclined plane taken at the line A" B of Fig. 4. Fig. 4 is a transverse verticalsection of the same, taken at the line C D" of Fig. 3. Y
In these furnaces the air-regenerators are arranged to communicate with one and the same side of the furnace, and the furnace-bed is thereby rendered accessible on all the other sides. Air only passes through the reversible regenerators to the furnace, and gas enters the chamber in a continuous manner from lthe source of supply through the gas-inlet, which is situated belowand between the air and com bastion-product passages. The gas-inlet is of such a width and so arranged with reference to the passages communicating with the regenerative chambers that the gas from the generatoris caused to expand laterally beneath the air-currents.
The gas-producers7 reversing and regulating valves are not shown inthe drawings, as they are of my usual well-known construction, and therefore need no description.
The gas produced rises from the producers continuously and flows out through the regulating slide-valves into the gas-flue, along which it passes through the port B to the chamber A of the furnace. Thus, gaseous fuel ows continuously through port B, while the lateral ports C serve alternately to give ingress to the hot air and egress to the products of combustion, as described in United States Letters,
IOO
Or revolving hearth at which the gas and air enter, and the products of combustion leave thecombustion-chamber. Therevolving basin is located within a transverse passage extending entirely under the combustion-chamber, and mounted upon a car, E, in such a manner as to be capable of revolution in a horizontal plane or about a vertical Or inclined axis. The said car is provided with wheels e, which run upon the track F, and may be readily withdrawn when it is desired to remove the revolving basin from its position beneath the com bustion-chamber.
The basin may be rotated by many mechanical appliances now in use, which will readily suggest themselves to a practical mechanic, and may be operated by any suitable motor adapted to impart continuous rotary motion or motion capable Of being increased Or diminished at will. I have found the mechanical combination illustratedin the drawings a good one for these purposes.
The axis upon which the basin is mounted is guided by a proper bearing, n, :1nd the rollers o, upon which the basin runs, travel upon a circular track, m, which forms a part of the car E. Continuous rotary motion is imparted to the basin by means of a worm-wheel, which is operated by the tangent-screw Y. The rotary motion thus imparted may be rendered variable or intermittent by the use of a proper motor. When the plane of rotation is inclined Or at an angle with the plane of the horizon the construction of the car and circular track will be modified accordingly. When the r0- tating hearth Or basin revolves about an in olined axis the Hue communicating with the gas-supply is inclined from the horizontal, as are also the air and combustion-product passages, in order that the gas and air may be mixed upon the most favorable conditions and complete combustion effected.
I claim and desire to secure by Letters Patent of the United States- 1. A regenerative furnace having a removable revolving hearth, inclined top, and downwardly -inclined gas-passage, through which the gas en ters continuously from the source of supply.
2. A regenerative furnace having a revolving hearth, an inclined top Or crown, and a gas-inlet located below and between the air and combustion-product passages.
In testimony that I claim the foregoing I`
