VISUAL SIGNAL.

Application filed. August 18, 1925. Serial No. 50,894.

This invention relates to visible signal interpose between the whistle valve and the means adapted especially to be used in conmixing chamber a secondary. or relay valve nection with air operated whistles on vessels 4:. Referring first to Figs. 2 and 5, said 55 without steam whistles, such as motor ships, valve is shown in the form of a piston 5 5 motor boats and submarines.

This renected up to any type of air or gas operated sults in a decrease in the air pressure behind whistle, horn or other warning signal, and the piston, since the air then escapes through is shown as connected to a whistle 1 of the the port 13, the result being that the spring diaphragm type. When so used. it is operated 11 slows up and practically stops the piston 1 preferably by compressed air from the before or by the time the bumper strikes the whistle valve 3. A small pipe 3 leads from stop 12. As before stated, the air is led a point between said valve and whistle to a through the jet 16 into the mixing chamber smoke producingapparatus. Preferably I g Said chamber s located directly above on the end of thestem and strikes the cylin I the tank 22 containing the cloud producing liquid. Preferably but a single liquid is employed, which when the fumes therefrom are ejected into the air, produces-a cloud.

Chamber 17 is shown as connected to container 22 by pipe 23. Adjacent the bottom of the container or top of the pipe is placed a thin disc2i with a small aperture 25-therein. Said disc is shown as held in place by spring clip 26 and is for the purpose of preventing the formation of encrustations at the point where liquid enters the mixing chamber, it having been found that the liquid will drop back through the hole in the thin disc with out clogging the same.

In such an apparatus it is imperative to keep it tightly closed when the smoke is not actually being produced as otherwise the air and fumes fromthe Diesel engines of the ship quickly combine with the vapors in the chamber to form a thick deposit. For this purpose I have shown a cap or closure 55 which normally fits tightly on top of the opening 18 and may be provided with a rubber block 56 to seal the opening. Preferably I provide automatic means for opening said closure when the whistle is blown or when the signal is given; For this purpose I have shown the cap as provided with a laterally extending arm 27 secured to the reduced portion 28 of stem 8 as by nut 30. Said extension may also be provided with a downwardly extending skirt 29 to prevent foreign matter from entering the top of cylinder 6, enclosing spring 11. Adjacent the top of said extension 8 are also provided spiral flutes 31 which engage a squared opening 82 in the cover plate 33 of cylinder 6. By this construction it will readily be apparent as the piston 5 is raised, by the air pressure, the cap 56 will be simultaneously lifted and also rotated without the path of emerging smoke (see F 1g. 2 and also dotted line position in F ig. 5).

The entire device may be clamped to the ships funnel as by means of brackets 3536. Preferably I provide a shield 37 for enclosing the container 22 for the liquid. This is for the purpose of preventing too great variations in temperature in the liquid due to the suns rays and heat from thestack since high temperatures cause undue expansion of the liquid and also fuming. Also preferably 1 only partially till the container 22 as indicated by dotted line 22" to allow suflicient air space for expansion and contraction ofthe liquid. 7

In Figs. land 3 is shown a form of the apparatus especially adapted for submarines. In this instance the cap 55' is hinged at 39 to bracket 40 on the side of the chamber 17.

Said hinge may be provided with an eccentric 41 to equalize the pressure of the cap on the'top of 18 of the closure. On its opposite side, said cap is pivoted to a link 42 which is hinged to an extension 28 of piston valve 5. The valve mechanism in this instance is especially designed to prevent the possibility of any water getting into the system when the submarine is submerged. For this purpose the piston 5 does not itself open the valve or port 13 leading to the smoke producing apparatus but actuates an intermediate mechanism for doing so, and said valve is located so that any water leaking past the piston will not enter the valve but will collect at the bottom of housing 58 where it may be drawn off by petcock 59. As shown in Fig. 8 the piston 5 is provided with a downwardly extending stem a5 having a shoulder 46 thereon and also being provided adjacent its lower end with an enlarged and preferably hollow cylindrical portion 47 having a collar 48 at the base thereof. A compression" spring 11 bears at one end on said collar 48 and at the other end against the lower end 49 of the cylinder 6, thereby tending to hold the piston 5 in its lowermost position. Pivoted at 50 in housing 58 is an arm or lever 51. At its inner end said arm is provided with a fork 52 taking a round stem 45 and adapted to be engaged by the shoulder 46 when the piston 5 is raised. At its opposite end said arm 51 engages the top of a valve 53 which normally closes a port 13 leading into the opening 54 connected to pipe 15 which leads to the smoke mixing chamber 17. Said valve is shown as normally closed by spring 55 but is opened when struck by arm 51. When the whistle valve is opened, therefore, air enters the housing 58 and cylinder 6 through the pipe 3 raising piston 5 upwardly against the spring until the shoulder 46 strikes the fork 52 thereby rotating thearm 51 and opening valve 53. This permits the air to flow through channel 56 and port 13 to the mixing chamber 17. y In this form of the apparatus also I provide an extra tank 60'connected to the liquid container 22" by pipe 61. Said tank is for the purpose of allowing free expansion of the liquid in the container 22' so that theliquid will not push up through the pipe 23 and into the mixing chamber owing to the temperature variations. In accordance with the provisions of the patent statutes, I have herein described the principle and operation of my invention, together with the apparatus which I now consider to represent the best embodiment there of, but I desire to have it understood that the apparatus shown is only illustrativeand that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combination and relations described. some of these may be altered and others omitted without interfering with the more general results out lined, and the invention extends to such use.
