OIL-WELL-CONTROLLED FIRE EXTINGUISHER.
Application iled September 17, 1926. Serial No. 136,151..
The present invention rela-tes to a device for automatically shutting otl flowing oil wells which have accidentally caught on lire just after they'have been drilled into the product-ion.
An important object of the invention is to provide a device of this nature which is exceedingly simple in its construction, inexpensive to manufacture, thoroughly efficient and reliable in operation, and otherwise well adapted to theV purpose tor which it is designed.
llVith the above and other objects in view,
as will appeal' as the description proceeds, the invention resides in certain novelfeatures of construction and in the combinationv and arrangement or' parts as will be hereinafter more fully Y described and claimed.
Tn the drawing n Figure 1 is a top plan view of the apparatus embodying the features of my inven tion.
Figure 2 is a transverse sectional view through the apparatus.
Referring to the drawing in detail, it will be seen that the numeral. 5 denotes a plate which in the present instancey is rectangular in formation merely'by way of preference. A lug G ext-ends from one edge ot the plate and'a smaller lug 7 extends from the same edge ot the plate in 4spaced relation to the lug 6. A bell crank lever 8 is pivoted as at 9 on the lug l7 and a fuse 10 isdisposed between the lugs G and 7. A latch ill is pivoted vas at 12 on the plate 5 and has a link connection 14 with the bell crank 8.
A spring 15 is engaged with one end ot the latch 11 and anchored as at 16 on the plate 5v and normally tends to move the latch 11 to a released position, the bell crank 8 and fuse 10, however. holding said latch.
11 in an engaged position.
lThe letter T denotes generallly a tool which has an intermediate portion 17 with a hexagonal opening 18 for engagement with the operating portion of a valve. The exterior edge ot the intermediate portion 17 is rounded and guided in arcuate members )D 19 rising 'from the plate 5. Arms 20 and 21 radiate .trom the intermediate portions 17.
A reduced extension 22 is formed at the terminal ci' the arm 2O and is engaged by the latch 11 as shown in the drawing. A pair ot springs 24 are anchored as at 25 to the plate 5 and have mounted at their `free but the. latch-11 prevents this as ends, sheaves or pulleys 26. Cables 27 are engaged as at 28 with the ends of the arms iand 21 and are trainedv over the sheaves 2G and are anchored as at 29. These springs normally have a tendency to pull the cables so as to swing the .tool T tov close the valve, long as the fuse 10 is intact. v f
Spring buffers 30 are'mounted in keepers 31 provided on the plate 5 and the arms 2O and 21 come into engagement therewith when -the springs 24 move the tool to its valve closing position. A' cable 32 is trained over a pulley 33 Ajournaled in a kbracket 34 on the plate and is engaged with the eX- tremity ot the arm 21 as at 35. This cable 32 is windable on a drumB mounted in any suitable manner on the plate and operable Y by a crank'37. It will`thus be seen that after the fuse 1Q has been. destroyed by fire, the spring 15 is reeto rock the latch 11 so as to release it from engagement with` the reducedV extension 22,v so that the tool will be rotated :in a counter-clockwise direction for shutting olf the valve because of the springs jldlhen'thevalve is thus shutoff and it is desired to yopen the valve, this may be accomplished by turning crank 37 and winding the cable 32 on the drum 36,'thereby resetting the parts whenanew fuse Vis put in place.
It is thought that the construction, operation, and advantagesofmy invention, will now be clearly understood by those skilled in this art without' a more detailed descrip tion thereof. The present embodiment of the invention `has been disclosedin detail merely by way of example, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
It will be quite apparent that numerous changes in the details of construction, and in the combination andV arrangement of parts may be resorted to without departing from the spirit or scope of the invention as as hereinafter claimed, or sacrificing any oi. its advantages.v
Having thus described my invention, what l claim as new is 1. A device of the class described including a plate, a valve shutoif tool rotatable above the plate and adapted to operatively engage a. valve, means associated with said tool tending to swing it to shut O.' the valve, a latch associated with said tool for holding it in its valve open position, means tending to release the latch from engagement with said tool, and 'luse means for holding said latch in an engaged position with said tool.
2. A device of the class described including a plate, a tool movably `mounted above the plate, means associated With the tool tending to dispose it in one position, a spring i'eleasable latch engageable with the tool for normally holding it in another position, a bell crank rockably mounted on the plate, a connection between the bell crank and the latch, and a fuse associated With the bell crank for holding said latch in its tool-engaging position.
3. A device ot' the class described including a plate, a tool inovably mounted above the plate, means associated with the tool tendingk to dispose it in one position, a spring releasable latch engageable Wit-h the tool for normally holding it in another position, a bell crankrocliably mounted on the plate, a connection between the bell crank engaging position, and means on the plate for re-setting. the tool.
l. A device of the class described including a plate, a tool including an intermediate portion tor engaging with a valve and rotatable'above the plate-and arms radiating from the intermediate portion, springs, pulleys on the springs, one end of the springs being anchored to the plate, cables ti'ained over the pulleys and having ends anchored to the plate and the other ends engaged With the extremities of the arms and tending to rotatey said tool and operate the valve, and fuse controlled latch means associated with one of the arms to hold the tool in inoperative position. v
5. A device ot the classdescribed including a plate, a tool including an intermediate portion for engaging with a valve and rotatable above the plate and ai'ins radiating trom the intermediate portion, springs, pulleys on the springs, one end ol the springs being anchored to the plate, cables trained over the pulleys and having ends anchored to the plate and t-lie other ends engaged with the extremities ot the arms and tending` to rotate said tool and operate the valve, a latch pivotally mounted on the plate and engageable with one ot the arms to hold the tool in inoperative position, a spring associated with said hitch tending to dis-- engage the same from the arm, a bell crank rockable on the plate, a` link connecting the sell crank with the latch, and fuse means tor holding the bell crank in a position to hold the latch in engagement ivith said last mentioned arm.
6. A device of the class described including a plate, a tool including an intermediate portion for engagng With a valve and rotatable above the plate and arms radiating` from the intermediate portion, springs, pulleys on the springs, one end of the springs being a chored to the plate, cables trained over the pulleys and having ends anchored tothe plate and the other ends engaged with the extremities ot the arms and tending to rotate said tool and operate the valve, a latch pivotally mounted on the plate and engageable With one ot the arms to hold the tool in inoperative position, a spring associated with the latch tending to disengage the same from the arm, a bell crank rockable on the plate, a link connecting the bell crank Ywith the lat-ch, tuse means for holding the bell crank in a position to hold the latch in engagement with said last-mentioned arm, a cable engaged with the Vother arm, and a drum rotatable on the plate on Which the lastnientioned cable is Windable for moving the valve to its normal position after it has been operated.
In testimony whereof I aliix my signature.
