FLASHER.
Application filednpril 30, 1925;
My invention relates to a fluid actuated 'levice for permitting an intermittent flow t fluid such as and is particularly adapted for embodiment in what may be termed a flasher for use in lighthouses, buoys or towers on air routes and the like.
Heretotore flashers have been developed which depended upon magnetic devices for effecting the proper operation thereof.
It is an object of my invention to provide a flasher of novel construction in which the gas or other fiuich which is afterward consumed actuates the mechanisi'n for effecting intermittent flashes.
It is another object to provide a flasher in which a valve and fluid actuated means are mechanically and adjustably connected by novel means.
It is still another object to provide a valve 20 which when open will be partially or substantially balanced so far fluid pressure is concerned.
It is a further object to provide improv c means ror throttling; flow of fluid and at as the same time filtering out foreignmatter.
It is another object to improve certain combinations and mechanical details of construction in a flasher.
Briefly stated in the preferred form of the an invention embodied in'a gas flasher, I employ a chamber into which gas under suitable pressure is conducted. There is a valve for controlling the distribution of to a consuming device such as a burner. A diaphragm or the like is movable under the influence of the fluid pressure in the fluid chamber. Means is interposed between said diaphragm and the said valve which upon movement of said diaphragm under fluid pressure, is adapted to cause movement of said valve. The said means may be adjustable so to vary the time of actiiiation oi the valve and thus vary the period between the flashes. When the device is used as a gas flasher a constantly burning pilot light is preferably employed'tor igniting the gas flowing atintervals to the burner.;
In the drawing I have shown for illustrative purposes only. a pref-erred form of the invention, which drawing illustrates a substantially central sectional view of a gas flasher. In the drawing k 1 indicates a gas chamber into which gas is conducted from an inlet connection 2, which in turn is connected.- to a source of gas Serial No. 27,120.
supply preferably including a reducing valve (not shown) for supplying the gas at the desired pressure. 3 indicates a valve block provided witha valve chamber 4. The block 3 is supported upon andin spaced relation to the main bodyv block 5 by means of a spider member 6. The block 3 is secured, preterably detachably, to the spider 6 by means of screws 77. This construction permits a ready removal of the valve block 3 in case it becomes necessary to repair or renew the same. burner head which may be secured to the block 3.
In the form showm-one side of the chamher 1 is closed by means such as the diaphragm 9 which may be secured between the lower end ofthe spider 6 and the main body block 5, so as to form a gas tight connection. Aspring or the like 10 serves to urge the diaphragm toward the collapsed position. A tubular sleeve 11 is fixedly secured to the diaphragm 9 by means of a nut 12 and a spring abutment 13 may be threaded or otherwise adjustably secured on the upstanding sleeve 11. A stem 14; may be slidably housed and guided in the sleeve 11 and in order to permit a restricted telescopic movement between the stem 14 and sleeve 11, the latter. may be slotted as at 15 to receive a pin or key 16 carried by the lower end of the stem 14:. It will thus be seen that the sleeve and stem may move relatively to each other to a slight extent but accidental removal ot' the stem from the sleeve will be prevented. A second spring abutment 17 may be thread ed or otherwise adjustably secured on the stem 14 and a spring 18 may be interposed between the abutmonts 13- and 17 so as to normally urge the parts 11 and lt into extended position.
The valve block 8 may have a sealing member such as the diaphragm 19 secured thereto as by means of a nut 20 which may be apertured to receive and guide the upper end 21 of the stem 14-. The valve block has a gas passage 21 connecting the gas chamber 4- with the pipe 22 or other connection leading to the jet as will be later described, and it is for sealing this passage that the diaphragm 19 is employed.
In the preferred form the valve 23 when closed rests uponan annular seat 25 and the pressure is above the valve and thus normally tends to maintain the same in 8 indicates what may be termed a closed position. The outlet for the fluid beneath the valve is preferably restricted so that the flow through the outlet 21 must be at aslower rate than that at which the fluid may pass between the seat and the valve so that when the latter is unseated the fluid pressure on the valve will be partially and in some cases substantially balanced. As one means of providing such a'restricted outlet I may employ a second inner and concentric valve seat 26 in the chamber 4 and it will be evident that when the valve is in open position, fluid under pressure may enter between the seat 25 and the valve at a much greater rate than it may pass between the valve and the inner seat 26. A spring or the like may be positioned above the valve 23 for urging the same toward the closed position.
In the gas inletpassage to the chamber 1, I preferably form an enlargement which if desired may be formed directly in the base member 5. In this enlargement or chamber is packed a quantity of fibrous material suehas asbestos wool 30. This asbestos wool serves to throttle the passage of gas from the pipe 2 into the chamber 1 and also serves to remove foreign matter such as dust and the like which may sometimes come over with the gas from a gas container. In order to further control the flow of gas into the chamber 1, I may employ a. needle valve 31 or the like which may be moved in either direction by means of a knurled nut 32. W hen the needle valve 31 is moved inwardly, the fibrous material is compressed so that the interstices are reduced in size and the flow of gas consequently throttled. A pipe preferably connected to the same source of supply as that connected to the pipe 2 conducts gas to the passage 34 in the burner block 8 and in this block I preferably provide a similar form of gas filtering and throttling device as that just described. As shown in the burner block, there is a quantity of fibrous material seated in an enlargement ot the passage 3st. This gas from pipe 33 after passing through the fibrous material enters a pipe 36 which is connected to a pilot burner (not shown) and furnishes a continuous supply of gas thereto.
The operation of the device is as follows:
Gas under the desired pressure is conducted through the pipe 2 and through the fibrous material and into the chamber 1 where the pressure builds up and raises or expands the diaphragm 9. W'hen the diaphragm is raised to such an extent that the upper end 37 of the sleeve 11 engages the abutment 17 on the stem 14; (the spring 18 during this operation being compressed), the upper end 21 of the stem acts through the sealing diaphragm 19 to engage the valve stem 24 and raise the latter against the pressure or the spring 27 and the fluid pressure acting above the valve 23. As soon as the valve 23 is raised slightly, gas flows between the valve and the outer annular seat 25 at a relatively rapid rate and the pressure there of underneath said valve at least partially balances the pressure on the opposite side thereof. As soon as the fluid pressure is partly balanced, the spring 18 which was previously compressed overcomes the pressure of the spring 27 and throws the valve 23 to open position with a snap action. New with the valve open,the accumulated gas from the chamber 1 flows through the con-, necting pipe 38 into the valve chamber 1, then beneath the valve past the inner valve seat 26 down through the passage 21, then through pipe 22 to passage 39 which is connect-ed'to any suitable type of gas burner 10 on the block 8. As the pilot light is always burning the gas flowing through the passage 39 to the jet 1O will be ignited so as to give a flash.
The various passages are so proportioned that the gas is consumed at a greater rate than it is permitted to enter the chamber 1 through the pipe 2. It will thus be evident that the gas pressure in the chamber 1 gradually diminishes and as it diminishes the spring 27 and the gas pressure acting above the valve 23 and the spring 10 acting above the diaphragm causes the latter to be forced inwardly or to collapsed position.
When the valve 23 is closed the spring 27 and whatever fluid pressure may be. in the chamber 1 maintains the valve in closed position until it is again actuated as previously described.
' It will be obvious that it there was a rigid connection at all times between the valve stem 24 and the diaphragm 9 that each very slight increase in pressure would raise the valve and there would be a succession of very brief flashes or flickers; in other words, there would be what might be termed a chattering ot the valve.
It will be equally plain that it the valve is actuated by the diaphragm only when the upper end 37 on the sleeve 11 engages the spring abutment 17, the farther apart the parts and 17 are positioned, the less frequent will be the actuation of the valve. I have, therefore, shown the abutment 17 being adjustably mounted along the stem 14 so that it may be positioned at any practicable distanee from the end 37 of the sleeve so as to vary the number of flashes per unit of time between any desired practicable limits.
