Be it known'that I, JOSEPH Kno CHUN improvements in ventilating devices and particularly to ventilating devices forshipsi One object of the invention. is topjrovidea ventilatlng device having-a valve which is adapted to. be held in' open position for the cally closed when water begins'to passinto the ventilator, due to highseas, rain, or other passage of air, but which will be automaticauses.

Another. object is lto provide a ventilator .valve which is arranged to be normally, held in open 7 means iventilatin m position and which is adapted tobe released I from the holding ventilator, the valve being then automatis may latched into closed position. Y, Y

pipes are extended'through the port-holes.

In either arrangement of the pipes water gets into the 131136821116. passes from one compa-rtment to another. with the result that the ship will become flooded.

The particular object of the present invention is to provide a means for closing the valve 111 the ventilator pipe when a sufficient amount of water has entered, and thus pre vent the; entrance of more water. Theinvention also contemplates the use of a detent for holding the valve in open position for the free passage of air, butwhich isarranged to be released automatically by an electroe magnetic means, the circuit through which? P eferring part'cularly'to accompanymg drawings, 10 represents a,',vcnt lator pipe which is properly supported throiigh a'n.

Carriedby one face of the dislc and par are the right angularly extending, allol metal legs 16, each havingits nee eiid formed with a, contact point 17. Mounted in thepipe, in position to receive the said points of the legs 16, are the stationary contactsoclzcts 18, disposed within the block of insulation 19. From the contact sockets 18 wires 20 and 21 extend, respectively, through 22, and to one side of a source of current 23 24;. A wire 25 connects the switch with one side oi the sourceof current, whilea wire 26 leads from the otherside of the source. 'Pivotally mounted on ae'suitable block 2'7, in the pipe, and adjacent the first block 19, is a detent hook 28, which is arranged to engage is in horizontal position, as shown in Figure by means oi the switch a 5, a coil spring 29 being connected to the detent and the block to normally urge the detent into disk engaging position. Secured to the rear portion of the detent, and extend ing downwardly away from the detent, is a curved arm 30 having an armature plate 31 on its free end for movement toward and away from the electromagnet 22'. When the armatureplate isattracted by the electromagnet, the detent will be released fromthe disk, and the disk rocked into closed position by its spring 15. In the offset portion of the" pipe is disposed an insulated member 51" in which vthe endspfthe wires 20 and261are embedded and have their tips exposed for contact by water which might enter the pipe, and through which the circuitis closed to V energize the" electro-1nagnet'. A- pivoted,

The shaft of the disk is provided with a knob or handle 34, disposedextei'nally of the pipe,to permit resetting the disk in open po- I.
