JAMES H. BELL, OF ST. LOUIS, MISSOURI..
FIRE-EXTINGUISHER.
No.e64,149.
To all whom 'it may concern:
Be it known that I, JAMES H. BELL, a citizen of the United States, residing at St. Louis, in the county of St. Louis City and State of Missouri, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is a specification.
This invention is a iire extinguisher for oil or gas wells and has for its object to provide a simple and elicient device of this kind, and also one which can be easily operated.
The device comprises a tapering plug which is dropped into the well-tube and smothers the fire. Means are provided for the escape of gas from the plug.
In the accompanying drawing, Figure l is an elevation of the invention showing the application thereof. Fi 2 is a longitudinal section. Fig. 3 is a top plan view. Fig. 4 is a cross-section on the line 4-4 of Fig.' 2.
Referring specifically to the drawing, 6 denotes an elongated conical plug which is hollow, its bore 7 forming a water-chamber. The plug has a removable tip 8 which is secured by screwing it thereon. On diametrically opposite sides ofthe bore 7 the block has longitudinal passages 9 which extend from the top of the plug and open into the sides thereof about midway between its ends. In the top of the plug are iitted stop-cocks l0 for the bore 7 and stop-cocks ll for the passages 9. To the top of the plug is also secured an eye 12 for attachment of a hoisting device.
In use, the chamber 7 is filled with water and the plug is inserted into the tube of the burning well, the
Specification of Letters Patent.
Application tiled May 29. 1907.
Patented Aug. 27, 1907. Serial No. 376,368.
cocks ll being left open to permit the escape of gas through the passages 9. The cock l0 is also left open in order that any steam which :may form in the waterchamber 7 by reason of the heat from the fire may escape. The water prevents the plug from getting hot enough to set the oil or gas on fire. If steam is made, the water-chamber will be relled. As the needle descends in the Well-.tube the iire is gradually smothered after which the oil will commence to flow from the cocks 1l whereupon they are shut off. If the diameter of the well-tube is such that the plug will not t tightly, the top of the tube can be packed with a ring of clay or other non-combustible material.
I claim:
1. A re extinguisher for gas and oil Wells comprising a plug adapted to he inserted into the Well-tube, and having gas outlets.
2. A tire extinguisher for gas and oil Wells comprising a plug adapted to be inserted into the well-tube, and having gas outlets and a chamber to receive a cooling medium.
3. A fire extinguisher for gas and oil wells comprising a plug adapted to he inserted into a well-tube, and having gas outlets, and valves controlling said outlets.
4. A fire extinguisher for gas and oil wells comprising a conical plug adapted to be inserted into the well-tube, and having' longitudinal passages extending from the top and opening into the sides of the plug. In testimony whereof I atlix my signature, in presence of two witnesses.
JAMES H. BELL.
