UNITED STATES PATENT Io IMPROVEMENT yIN STEAM-GENERATORS."
Specification forming part of Letters Patent No. 58,038, dated September 1l, 1866.
.To all whom it may concern:
Be it known that we, WILLIAM LoUIs WI- NANS and THOMAS WINANS, of London, England, have invented Improvements in the Arrangement of Apparatus for Snperheatin g Steam in Steam-Boilers; and we do hereby declare that the following is a full and exact description of our said invention.
This invention of improvements in the arrangement of appara-tus for superheating steam in steam-boilers consists in arranging the superheating apparatus in the manner described, so that the admission of the heated gases, which pass from the tire-place through the tubes to the superheater, may be regulated by the attending engineer, so as to cause the whole or any desired proportion of the heated gases to pass through the superheater, or so as to cause the whole of it to pass directly to the chimney without entering the superheating apparatus, by which means the steam may be heated to any practically-useful degree of temperature.
To this end the superheating apparatus is placed in the smoke-box or in the uptake, or in any suitable and convenient place in the ilue or'passage between the lire-place and the chimney, and is provided with a valve or valves, whereby the admission of the heated gases from the :fire-place into the superheater may be regulated at pleasure.
By means ofthe valve or valves the hot air or gases, after passing from the fire-place through the hue-tubes of the boiler, may be made to pass either through a passage communicating directly with the chimney, or they may be made wholly or partly to pass through the superheating appara-tus.
By this arrangement of apparatus and the proper adjustment of the valve or valves the steam may be kept constantly superheated to any required and useful degree of tem perature,
' and, when it is preferred not to use superheated steam, the hot air or heated gases may be shut .off from the superheating apparatus by closing the valve or valves which open the communication between the superheater and the iiue or passage.
By this arrangement of apparatus the hot air or heated gases may be shut off from the superheater when steam is being got up in the boiler and when the machinery is at rest and no steam is passing through the superheater. Therefore the tubes and other parts of the superheating apparatus will not be damaged by becoming overheated when not in use.
in the accompanying drawings, at Figure l, the superheating apparatus is shown as applied to a vertical tubular boiler; but only so much of the boiler is shown asis necessary to show the application of the present invention. Fig. 2 is an external elevation of the same; and Fig. 3 is a sectional plan view ot' the same.
The particular form of vertical tubular boiler to which we have shown the invention as applied is one that we have invented, and for which we have obtained Letters Patent.
The boiler has a vacant space, a, Fig. l, in the center, for the convenience of allowing a man to get down and examine and clean the internal parts of the boiler, and to give a free and better circulation ofthe water in the boiler, as described in the specification of the other Letters Patent, above referred to. This space is surrounded by the tine-tubes b b, up which the heated vapors and gaseous products ot' combustion pass, either directly to the chimney through the open annular space c c, which surrounds the steam-dome d, or they may be directed through the superheating-chamberc, in which are arranged a series of circular tubes, fff, which communicate with the upper part ot' the boiler, so that steam is caused to circulate therein and be superheated when required.
Beneath. the open end of the superheatin gchamber are arranged a series of valves, g g y, mounted on spindles, which also carry other valves, g* gx gx, for closing the entrance to the annular space c when it is required to direct the heated gases into the superheatingchamber. At the outer ends of these valvespindles are mounted the sector-pieces h h h, as seen best in the detached plan, front, and end views, Figs. 4, 5, and 6, of these valves an d their appendages.
The sector-pieces h are connected by chains or metal bands to a ring, t' c', which surrounds the boiler, as seen best in Fig. 2, and is snpported on the sector-pieces, on which it simply rests, as seen in Figs. 5 and 6, so that it may be moved round horizontally in either direc- 2 esmas tion, in order to act on the spindles of the valves g g, and thereby raise or lower the latter. This horizontal motion of the ring iis effected by means of a tangent-screw, j, which is supported in brackets secured to the sides of the boiler. 0n this tangent-screw is mounted a stud-block, 7c, and it is provided at one end with a bevel-wheel, l, which is driven .by a similar wheel on the upper end ofthe vertical shaft m, which is provided at its lower end with a winch-handle, wherebyitinay be turned in either direction.
It will be understood from the foregoing description that by closing the valves g g the heated vapors will be prevented from entering t-he supcrheatin g apparatus, and consequently the steam in the circular pipes or tubes f f will simpl)1 be common steam.
rlhe operation of the several parts will be as follows: Supposin g it be desired to superheat the steam which is circulating in the pipes or tubesff, the valves gg will be open and hang down in the position shown in Figs. 1 and 5, and at g in Fig. 6, the smaller valves gX gx being brought into the position shown in the figures in. order to close the lower end of the circular space o and prevent the heated gases from passing through the same. The heated gases from the tire-will therefore pass up into the superheating-chamber, and will circulate among the tubesj'f, which will abstract aportion of the heat therefrom.
It will be seen, on referring to Fig. 6, that the two valves g and gX are connected together by a link, a, and therefore these two valves must always work together.
If it be desired to put the superheating apparatus out of work this object may be effected by simply turning the winch-handle at the end of the vertical shaft m, so as to move the ring z' around, and thereby cause the spindles of the valves g and g) to turn on their axes, thereby closing the valves g and opening the valves gx. The heated gases will then be prevented from passing up into the superheating-chamber, but will he forced to ascend through the annular space c and pass direct into the chimney.
It will therefore be Aunderstood that the superheating of the steam will be entirely under the control of the engineer in attendance, as the heated gases may all be made to pass into the superheatiiig-chamber, or all into the annular space, or bot-h these channels may be partially open, as indicated by dots in Fig. 6, so that part of the heated gases will pass through the one space and the remainder through the other. Y
YHaving now described our invention and the manner of carrying the same into effect, we claimrllhe combination and arrangement of the valves g, valves 9*, sectorpieces h, ring i, tangent-screw j, block 7o, bevel-wheel l, the circular tubes j', dome d, space a, tubes I), whereby the heated vapors may circulate among the tubes f or pass through the space c surrounding the dome, as may be desired, substantially as described, for the purpose specified.
In witness whereof we, the said WILLIAM Leurs Winans and THoMAsWINANs, have hereunto set our hands and seals the 20th day of January, 1866. v
