Definitions

  • This vinvention relates to a small device which, located on the valve of a closed vessel containing a gas under pressure,einits a continuons whistling as soon as rthe internal e pressure'in'the vessel, owing to 'any causeV whatever, no longer reaches the predeter-l mined minimum of pressure.
  • the same is especially suitable as deflation signaller for vehicle pneumatic tires.
  • e Y E0 This device consists'siibstantially Iof a boX screwed on the valve of the vessel, which must Anot be completely closed.
  • Said box encloses a setof 'valves and diaphragms under influence of the internal ressure which by fist againstthe actionofa spring,'a;whistle forcedA home in a socket.
  • the internal gas pressure ishigher than the strength of the spring, such pressure presses on the whistle,-whicli latter is tliuslield in its socken-,the boss of ⁇ the outer diaphragm, driven out by the air under pressure; but asV soon as the internal pressure'ceases balancing the strength of the spring the whistle is forced out of its socket,
  • Figs. 1 and 2 illustrate, in double natural size, an axial vertical section of the device, open (alarm position) in Fig. 1, and' closed (inoperativeposition) inv Fig. 2. .Y
  • - rIzligsj and 4 are front and side views re-V 49 spectively, of the device in natural size.

  • av first, nontight valve consistingV of a disc 6 the diameter of which is somewhat smaller than the diameter of the opening in the ring 54, but provided wtih a' base flange 61, of somewhatlaigerdiameter, kto'abut against the Vunder face of the ring; through said disc f passes a soft rubber cone 62, the base of which serves asfresilient stop guard fo-r disc 6, whilst itsupper part,endedvwith ai reinforcing and ⁇ guiding pin' 63, serves asobtiirator for the lcanal in the diaphragm to ybe described later on.

  • the diaphragm 7L consists of a thick cap of r .soft rubber, hermetically fitting on thegan! 'nularinternal projection 52 in box 5.A In the center-bore Vof said cap, is forced the bottom of atubular piece 71, with dome shaped top, in the upper partof the bodyof which is bored ⁇ a side opening 72; ⁇ on thebody of said piece 71 is fastened a disc 7 3 of ⁇ a diameter somewhat smallerthanthe diameter of the diaphragm 7 and having in its centena' com-5.

  • Said lid 8 is boredv in its center with ahole 83 in* ⁇ which loosely engages the .upper por# ⁇ tion ofthe tubular part 72' which projects 9 made in one piece with same.
  • said socket is arranged a whistle alarm element 10, of ordinary construction, the bottoni of which is closed by a removable cap 104 fastened by a pin 105; the body of said whistle 10 is guided and slides loose in the contracted part 91 against which abuts and stops a sleeve 101, fastened in the whis:
  • the mounting and working of this device are as follows:
  • the nut of the valve spindle ot the suitably inflated tire, is slightly loosened (for instance of half a revolution) so that a pressure Von same will allow air to escape 'from the tire.
  • the neck'l is then screwed on said valve, by this screwing down, the conical rubber sleeve forces Adown the valve spindle and the small quantity of compressed air escaping, passes through the hole l in the bottom of box 5, between disc 6 and ring 54, and collects under the diaphragm .7.
  • the spring 103 which tends to project the whistle out. being calculated or adjusted ,to a strength less than said normal pressure (preferably to a strength corresponding to the minimal pressure permissible in .the tire, for instance 4i kgs. for a tire the normal pressure of which ought to be 5 kgs), said spring 108 is held. inoperative oy the saidV antaga nist pressure and the 'whistle'v 10j remains locked in the'socket 9 (see position shown in Fig-2).
  • the whistle continues signalling to the driver so long as air escapes from the tire.
  • the driver wishes to stop the whistling, he grips the whistle by its head 104L and rotates it half an axial revolution which, by bringing the solid part of sleeve 101 against the head of piece 61, forces said piece back against the rubber lcone G2 which obturates it and closes the passage 71-7 2.
  • the invention consists in an hermetically closed device, connecting the vessel containing gas under pressure with a whistle7 and enclosing a set of valves and diaphragins arranged in such manner that the pressure of the internal gas produces the obturation of the passages leading to the whistle, so long as such pressure is higher than the strength of a spring especially calculated or adjusted to torce said whistle out, in its operative position, as soon as said internal pressure falls under a. predetermined level, this opening the passage for the gas to the ymouth-piece of the whistle and blowing the same.

  • a casing for connecting with an enclosure containing fluid under pressure having a bearing, a movable tubular whistle in the bearing, the casing having an opening to communicate With the inside of said bearing, pneumatically-actuated means in the casing and comprising a part to pass through said opening to engage the Whistle and normally hold it in the bearing, said means act-y ing-on a reduction of pressure of said fluid to vrelease the Whistle, and means for causing the Whistle to move When releasedinto position to sound an alarm indicating said reduction of pressure.
