TORPEDO Application ledAugust 20, 1930, Serial No. 476,652, and in Italy August 30, 1929:

v parts omitted, of an automotive torpedo equipped according to this invention;

Figure 2 is a fragmentary transverse section of the same on line 2 2 of Figure 1;

Figure 3 is a. fragmentary section on an enlarged scale of the. device of this invention for discharging compressed air from the compressed air vessel feeding the torpedo motor;

Figure 4 is a separate and fragmentary plan view of a detail on line 4 4 of Figure 3, with the torpedo shell removed;

Figure 5 is a fragmentary section on line 5 5 of Fig. 3.

As shown on the drawings, within the torpedo shell 1 is fastened a. rim 5 which Vconnects the torpedo head shell l with the air vessel 3 and provides a peripheral set of nozzles 6 connected with a space 7 left intermediate the bow wall 8 of vessel 3 and a partition 9 fastened on rim 5 and on a valve casing 10 located in space 2 within head 1.

In a cylinder 11 threaded in a central bore of front partition 8 of compressed air vessel 3 (Figures 1 and 3) is mounted to reciprocate a valve 12 having a balancing port 13 and a pilot valve 14 acted on by a spring 57 the stem of said pilot valve 14 having an outer head 15; the differential valve 12 14 thus pro vided controls air flow through

ports

16 and 17 of cylinders 11 and between the insideof vessel 3 and space 7.

In a sleeve 18 of casing 10 fastened on partition 9 a piston 19 is mounted to reciprocate, said piston having an adjusting screw 2O adapted to abut on head -15 and a 4throng-hout port 21; a link 23isifulcrumed at 22 on pis= `ton 19 and is pivoted at 24 with a similar ylink 25 fulcrumed at 26 on a piston 27 hereinafter described thus providingV a toggle gear', the interconnected ends of

links

23, 25 extending beyond bushing 18 through slot 61 of the same, while a port 56 connects the inside of sleeve 18 with the inside of casing 10 la piston 27 is mounted to move against pressure of a spring 28 in a seat 29 which is loose `in sleeve 18 and isl resiliently held in position therein by a spring 30 and a plug 31` fastened in the mouth of sleeve 18; n

A tube 32 leads from easing 10 to bow ballast water compartment'4 of torpedo (Figures 1 and 3). Casing 10`is encircled by a movable frame 33 (Figures 3 and 5)"whose bottom portion is connected by means oflrod 34 andv stud35 with a'slioe 36 fulcrumed'at 37 on a seat 37 of torpedo shell `1;

The frame 33 has a-tappet38 operative von a plunger 39 mounted' to reciprocate through casing l() and bearing on the ends of toggle.- links 23-25 interconnected by pivot pin 24, the top end'of said frame 33 is Vconnected by a rod 40-with a hydrostatic diaphragm 41 which is actuated byoutstanding water pressure against the action of a spring 42 which is seated in a seat 60 fastened by collar 52 on the torpedo shell 1.

ln lugs 43 solid with top plate 44 of diaphragm 41 a fork 45 is pivoted at 58; said fork being acted on by Vsprings 59'engaged with said fork 45 and plate 44 at 46 and 47 yrespec tively; said fork has an arm 48 whose head 49 may project outwardly through an opening 50 of a cover 51 closing the collar 52 and seat where diaphragm 41 is located; teeth'53 are provided on the pivot fork ends they being adapted to engage lower surface of cover 51.

The communication intermediate casing 10 and space 7 is made through ports 62 and is normally cut off by a tapering annular Valve 54 which is mounted to reciprocate on sleeve 18 and is forced by spring 55 on its seat provided in casing `10.

When the torpedo is in the launching ,tube therefor (not shown) shoe 36abuts on the internal surface of said tube and'said-'shoe 36 with trame 33 and parts connected therewith are prevented from moving, they being thus held in position shown in Figure 3.

When the torpedo has been lauched and in its run it tends to sink and reaches a depth for which diaphragm 41 and spring 42 have been set to operate, said diaphragm 41 moves inwardly against the action of spring 42, and then it is engaged in the position it takes up because teeth 53 of fork 45 under action of springs 59 abut on lower face of cover 51; then arm 48 is caused to carry the manipulating head 49 to outside of the torpedo shell 'for its subsequent manipulation.

The displacement of diaphragm 41 and of rod 40 connected with it causes frame 33 to move down it then freely moving in this direction, because shoe 36 connected therewith by rod 34 is :tree to swing outwardly around its pivot 37, said shoe being no longer engaged by the surface of the launching tube.

Frame 33 on moving down shifts plunger 39 downward, the

toggle gear

23, 25 being thus actuated at pivot point 24.

Piston 27 is first caused to move back against the action of spring 28 and then the spreading motion of

toggle gear

23, 25 after spring 28 is compressed causes a backward motion ot piston 19 whose stem 2O acts on head 15 and thus opens pilot valve 14 and then the main valve 12.

Then air compressed under high pressure within vesel 3 flows through 16, 13, 1'?, 21 into sleeve 13 and a portion of said air may ilow through tube 32 into compartment 4 to expel water contained therein, by a device forming the subject mattei' of my co-pending application tiled at the same date hereof under Serial Number 476,651.

The remaining portion of compressed air flows into sleeve 18 and issues therefrom through port 56, and then said air opens valve 54,' flows through ports 62 and enters space 7 from which it issues through nozzles 6 discharging it towards torpedo stern.

Air jets issuing from nozzles 6 and directed sternward owing to the water reaction produce on said nozzles and therefore on the torpedo an upward action; then the torpedo sits upright and the reduction of weight depending upon the air discharge is assisted by a positive upward action causing the torpedo to float.

Diaphragm 41 and stem 40 with parts actuated by said stem are held in the position they tool; up when the described operation is completed'by teeth 53 abutting on cover 51.

TVhen the torpedo has been recovered an operator acts on head 49 of Jfork 45 to release the gear and enable

valves

14 and 12 to close under the action of spring 57, the torpedo being thus in conditions for a subsequent loading and run.

The described arrangement provides for securing automatically the discharge ot air from vessel 3 and for obtaining an action which assists the torpedo buoyancy when the torpedo reaches a predetermined depth after being launched, while shoe 36 serves to prevent the operation ot the device and the discharge of the air when the torpedo is within a. launching tube of a submarine boat and this boat sinks at a larger depth than that for which the air release control means (as diaphragm 41) has been set.
