UNITED STATES PATENT OEEIcE JAMES C. MITCHELL, OF LANCASTER, NEW HAMPSHIRE.
-IMPROVEMENT IN GASWGENERATORS.
Specication forming part of Letters Patent No.166,288, dated August 3, 1875 application filed May 28, 1875.
To all whom it may concern:
Be it known that I, JAMEs C. MITCHELL, of Lancaster, in the county of Goos and State of New Hampshire, have invented a new and and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specication, in which- Figure l is a Vertical front elevation; Fig. 2, a detail of the air-tight furnace-door; Fig. 3, a sectional side elevation; Fig. 4, a sectional detail of one of the purilers.
This invention relates to certain improve- A ments in the manufacture of illuminating-gas,
designed to utilize any kind of fuel for the production of the gas, and applicable to limited manufacture, as for private families, &c. It consists in a retort placed within a furnace, or a common stove, if desired, and having an air-tight door of peculiar construction, and
a communication direct with the furnace, by means of which construction the gaseous contents of the retort may be drawninto the furnace and burned when the air-tight door is to be opened for drawing and recharging the retprt. It also consists in the peculiar construction and arrangement of the tops ofthe purifiersand an air-tight door to the retort, and the combination with the feedpipe to the gas-holder of a ball-valve to prevent back pressure, as `hereinafter more fully described.
In the drawing, A represents the retort, which is made of cast-iron or other suitable ,materiah and contains the wood, coal, fats,
or other material from which the gas is to be made. The front of said retort is made perfectly smooth, and is provided with an airtight door, P, which also has a smooth face. The said door is provided with a latch, a, anda spring, b, and the retort has a catch, c, the front side of said catch, against which the latch binds to prevent the opening of the door, being made inclined inwardly from the bottom to the top, so that when the spring forces up the latch the latter engages thesaid incline to hold the door tightly to the face of the retort. V is a pipe, having a lstop-cock, C, which leads from the retort A directly into the furnace B. Whenever the retort is to be recharged, or opened for any cause whatever,
the stop-cock Gis turned. The gaseous contents of the retort then pass, and the draft ofthe furnace, directly into the latter, and are consumed, and the door P of the retort may then be opened, the back pressure of gas from the holder and condenser being prevented byvalves and stop-cock. E is the outlet-pipe from the retort for the gas. rIhis pipe passes all around the retort in the furnace to insure the thorough decomposition of the undecomposed products of distillation, and communicates through a stop-cock, C1,
with` the condenser G. The latterI vessel has,
near its bottom astop-cock, C2, through which the distilled and condensed liquids are drawn off, and has a pipe, F, that passes the gas through the cooler H to the purifiers, which said cooler consists simply of a tank or trough filled with water and prov-ided with a suitable outlet. As the gas passes from the said cooler it enters one of two purifiers, I I, which are of a similar construction. These purifiers consist of upright chambers, having vats Xin the bottom, and detachable tables S S1 S2, resting one above the other, which are constructed of metal, with perforated tops, upon each of which lime is placed, and through which said perforations the gas passes, going up through one purifier and down the other. R is a de tachable connecting-pipe, which conducts the gas from one puriterto the other, and terminates at each end in a downwardly-opening detachable cover, J, for the purifiers, which rests in a trough, O, at the top of said purifiers,- which is lled with water, the connection between the two purifiers being thus a watersealed detachable one, so that the purifiers maybe readily inspected and the lime renewed whenever desirable. K is a pipe leadingfrom one of the purifiers to the gas-holder J, which consists in the usual tank filled with water, and an inverted cylindrical vessel resting therein and movingn guideways. Nisaballvalve, which rests in the top of pipe K, and which,"`while it allows the passage of the gas to the holder, prevents the back pressure. L
is the pipe that feeds the gas from the holder" to the burners.
With respect to my method'of disposing of the contents of the gas-retort, I am awareof the fact that the outpouring gases from the by expansion Opened retort-door have been gathered into an overhanging hood and conductedthrough a pipe into the furnace; but in this case the gases come inio contact withthe air and produce an explosive compound, Which, being ignited in the furnace, is liable to strike back and result in an explosion, and consequent injury to the Workmen. Itherefore limit my invention to the terms of the ciaim, in which the gas is conducted directly to the furnace Without admixture of air, and before the opening of the retort-door. l
Having thus described my invention, What I claim as new is- 1. The combination, With retort B, havin g a smooth face, of a door, P, having acorresponding smooth face, the latch a, spring b, and catch c, for the purpose of maintaining the door closed with an air-tight connection, substantiaily as described.
2. The combination, with the purifiers I I', having Water-troughs O, of the detachable tube R and the covers T, as and for the purpose set forth.
3. The combination, in a gaslgenerator, with the pipe K, terminating in the gas-holder, of a ball-valve, N, resting in the end of said pipe, for the purpose of preventing back pressure, as described.
4. The method of freeing air-tight gasi
