An object of the invention is 4to provide an escape Vfor submarines having a chamber with an ventrance, and an exit, with means within the chamber for closing the entrance to and the exit from the chamber.

Another object of the invention is to provide a chamber with a plunger for forcing Water from the chamber after the entrance has been closed and the exit has been opened to permit of the closing of the exit and the Withdrawal of the plunger from the exit with the chamber free from water.

Other obj ect-s of the invention are l.to provide means Vfor opening and closing a head vat the exit of the chamber, the said means being operable from within 'as well 'as from without the chamber, and to provide means operable from within as well as 'from without the chamber to .secure the door at the inlet. The plunger is preferably provided with a check valve or valves .and means are provided for moving the plunger in the cylinder. Means are also provided for locking the head at the exit from the chamber. Additional objects of the invention will appear in the following speciiication in which the preferred forni of the invention is described.

In the drawingsimilar reference characters refer to similar parts in the Aseveral views, of which f Figure 1 is a sectionalA view showing .the escape device in connection with a -submarine, a portion of which is shown in section,

Figure 2 is a sectional view `similar to the sectional view illustrated in Figure '1, but with the head at the exit ,from the chamber in open position, and

Figure 3 is a sectional view on the line 3-3 of Figure 1.

By referring to the drawing it will be seen that the escape device is arranged on a sub-v marine, a portion of which is shown in section at 5, the device including a chamber 6 which is preferably in the form of a cylinder and which has an exit opening 7 at'one of its ends and an inlet opening 8, which is preferably at the top of the chamber or cylinder 6. v The opening 7 is closed by a head 9 which is i pivoted at 10, the head 9 having a gasket 11 for engaging the'end of the cylinder to obtain a tight joint. Secured tothe head 9 there is an arm 12 which has a pin and slot connection 13 with a -rod 14, the rod 14 extending through an opening 15 inthe submarine, 55 which is provided with a stuhng box 16 to prevent leakage, the rod 14 being journaled in a bearing I7 in a depending gear box 18. The rod 14 is threaded, as shown at 19, and meshing with this thread there is a nut 20 having outer teeth I21 and an integral sprocket wheel22. 'A sprocket chain 23 is disposed around the sprocket wheel 22, by which means the nut y20 may be rotated and, as this nut20 and sprocket wheel 22 are rotated between a bearing 24 and the wall 25 of the gear box 18,fthe rotation of the nut serves to move the rod inwardly for outwardly, as maybe desired, to open orvclose the head 9. The chamber or cylinder ,6 has a depression 26 with a bearing 27 and journaled in this bearing l27 there is a stub shaft 28 on which there is mounted aear 29 which meshes with the teeth 21 of t e nut 20. At the inner side of ther'stub shaft '28 there is a handwheel 30 and it will, therefore, be :understood that by turning `the Ahandwheel '30 within the interior of the chamber or cylinder 6, it is lpossible to open or shut the head 9as may be desired.

Therefore, this head 9 may be opened or may be shut, ,eithervfrom within or from without the chamber or cylinder.

y The inlet 8 has an outwardly extending rim 31 'and a bracket 32, a door 33 being hinged to the bracket 32, this door 33 being preferably provided with a handle 34, by which means the door 33 may be conveniently opened or closed from within the chamber or cylinder '6. The door 33 has also an extending arm 35 which is positioned for engagement by alocking member 36,-this locking member 36 beingpivoted to a bracket 37 at the outer side of a hood 38 extending from the chamber or cylinder 6. This hood 38 has anv opening 39 through Whichis disposed an arm 40 on the locking member 36, the locking member 36 also has `an outwardly extending arm 41, so that the locking member 36 may be operated eitherfroinwithin or from without the chamber or cylinder 6. The locking member 36 is provided with an opening 42, so that when the locking member 36 is positioned as illustrated by the full lines in Figure l of the drawing, the arm on the door 33 will be disposed in the said opening 42 and will be held secured by engagement with asurface of the locking member 36. However, when the locking member 36 is moved to the position indicated by the dotted lines in Figure l of the drawing, the arm 35 will be free from the locking member 36, so that the door 33 may be opened, as illustrated in the dotted lines in Figure 1, Secured to the arm 40 at the inner side of the hood 38, there is a gasket or washer 42 which serves to prevent the escape of water from the chamber or cylinder 6 through the opening 39. v

Disposed in the chamber or cylinder 6 there is a plunger or piston 43, the plunger orpiston 43 having valve openings 44 which are normally closed by flaps or other check valves 45, which prevents fluid from passing from the chamber or cylinder 6 at the opening through the valve openings 44, while permit- 1 ting air to flow from the head 46 of thecylinder through the valve openings 44 into the cylinder adjacent its head 9. There are openings 47 in the head 46 which permit a flow of air through the head 45 to and through the valve openings 44.

The head 46 is provided with a bearing 48 and a bracket 49 is secured to the head 46,. a screw 50 being provided which is journaled in the bearing 48, this screw 50 also being journaled in a bearing 51 in the plunger or piston 43. Meshing with the screw 50 there is a nut 52 having sprocket teeth 53 around which a sprocket chain 54 is disposed. It willv be understood thatthe longitudinal movement of the nut 52 is prevented by the bearing 48 and the bracket 49, and that, therefore', vwhen' the nut 52 is rotated by the sprocket chain 54 and sprocket teeth 53, it will serve to move the screw 50, together with the plunger or piston 53,` longitudinally of the chamber or cylinder 6. Y l

The head 9 is provided with a threaded projection 55 which is disposed for disposal in a threaded opening 56in a member 57 which has longitudinal and rotary movement in a bearing 58 in the submarine 5. The member 57 is provided with a handwheel 59, so that when the threaded projection 55 is disposed at the threaded opening` 56 in the member 57, the handwheel 59 may be rotated to lock the threaded projection 55 in the member 57. A resilient packing-60 is disposed in the bearing 58 to permit the longitudinal and rotary movement of the member 57, as may be necessary, to secure and lock the threaded projection 55 on the head 9, while preventing water from passing through the bearing 58.

It will be understood that the device which has been described may be disposed at any desired place on the submarine and thatwith the head 9 in closed position and the plunger or piston 43 disposed adjacent the head 46, the door 33 may be opened, when a man may enter the chamber or cylinder 6, after which the door 33 may be closed, and should there be only one man remaining in the submarine, this door may be secured from the interior of the chamber by means of the arm 40, but where there are other men remaining in the submarine, the door may be secured, if desired, by means of the arm 4l. When the door 33 has been closed and has been secured,

the'member 57V may be turned to free the threaded projection 55, when the head 9 may be turned slowly, either from within or from without the chamber or cylinder 6, when the water will flow into the chamber or cylinder 6, and when the chamber or cylinder 6 has been filled with water, the man within the chamber may leave through the exit 7, the man being provided with a suitable means to withstand water pressure and to supply him temporarilyv with air. When the man has escaped, the plunger or piston 43 may be moved in the direction of the head 7 to expel water from the chamber or cylinder 6, after which the head 9 may be closed by the means which has been described and after which the piston 43 will be moved again to a position adjacent the head 46, the check valves 45 permitting air to enter the chamber or cylinder 6, when the door 33 may be opened again to Vpermit another man to enter the chamber or cylinder and make his escape in the manner described. It will be understood that when the member 57 has been moved to free the threaded projection 55, it will not be necessary to operate this member 57 to lock the door during the period between the escape of two sailors, inasmuch as the head 9 will be held in position at the eXit 7 by the water pressure. Therefore, when'one or more sailors are about to escape from the submarine, the member 57 will be moved to free the threaded projection 55 and this projection 55 will not be locked again during the escape of the crew from the submarine.
