VALVE FOR 'USE WITH SUBMARINE DIVING APPARATUS.

Patented Apr. 11. 1%11.

Application filed December 6, 1910. Serial No. 595,850.

To all whom it may concern:

Be it known that l, Cnns'ren E. Macncrrnn, a citizen of the United States, residing at the borough of l /lanl'iattan, city,

county, and State of New York, have invented an Improvement in Valves torUse with Submarine Diving Apparatus, of which structed to withstand the pressure of water at great depth such as that illustrated in my co-pcnding application Serial No.'595,84:7

- of like date herewith.

With armor of such character it is desirable to provide "an air pump attached within. a suitable casing, so

that in case the water pressure outside the armor is of sutticient force to cause a leakage of water through the joints of the armor, such water as may enter the armor from such cause can be pumped out; and the ob- ;ject. of my present invention is to provide a uniform supply of air to the diver at all times under normal conditions, and .to ad- .mit a sufiicient pressure of air to the pump to work the same for the discharge of water from the armor should leakage of the joints occur, in which case, and while the pump is working, the diver 1s supphedwrth a sulficlent quantity or airfrom the exhaustwhich .is discharged into the armor through a suitable spreader or mufller.

In the acconipanylng drawlngz Figure l isa vertical section of my improved valve. Figs. 2 and 3 are sectlons of the same atthe lines w, m, and y, g, respectively. Fig.

1 is the cylindrical valve casing havingtwo lateral tubular projections 2 and 3 eX- teriorly screw threaded, and also having intcrior annular recesses a and 5 fornnng air and 14 spaced apart in circular range.

spaces in line with the respective tubular projections, there being ports 6 and 7 communicating between said air spaces and the interior of said projections. A tube 38 is attachcdto the screw threaded end of the projection and passes into the interior of the armor 17. through an opening therein maden or that purpose, see Fig. 4.

The bottom of the valve casin 1 extends in reduced diameter below the tubular projection 13 forming an annular shoulder S,

which is providedwith an annular recess to receive and hold a circular ring 9 of rubber or'other suitable elastic substance.

Within the v: lve casing; 1 there is a cylindrical cup 10. with closed bottom and open top. A pin 11 projects downwardly from the under surface of the cup 10 at the centerand is surrounded by a spiral spring 12 which spring has a hearing at its top against the under surface of the cup 10. and at its bottom against the interior surface at the bottom of the extension to the valve casing. The cup 10 is of a diameter to fit closely within the valve casing 1, but has vertical movement therein without undue friction. This cup 10 is provided with openings 1.3 The spring 12 is of a. tension to normally maintain the cup 10 in such position that the openings 13 therein are in line with the annular recess or air space 4 in the valve casinn, and the port 6 therein.

The upper end of the valve casing is exteriorly screwthreaded to receive the interiorly screw threaded cap piece 15 which has a circular hub 15 on the top exteriorly screw-threaded with a central opening, and

a tubular cylindrical projection 15 extending within the casing 1 to a point slightly below the annular recess 4. This tubular projection 15 is open at its end within the casing 1. This valve is-prefcrably located within. the casing 16 attached to the back of the armor 17 which casing contains a pump 18;.thc alve being connected to the pump by a coupling 19 screwed upon the screwthreaded e'nd of the projection 3 of the valve casing. A pipe or tubing 20 is connected to the screw-threaded hub 15* of the cap 15, and passes into the interior of the armor 17 through an opening therein provided for such purpose. and is coupled or otherwise connected to a boss 21 on the interior of the I and is discharged into the open water armorthrough which boss and armor there is an opening communicating with an air port in an attachment 22 on the back 01' the armor -17. which attaclnuent is provided with conneetmns 23 for the air supply tube 24 and exhaled air tuhl These airt'ubes Q 1 and beyond their eonnection with the attachment 22 are preferably carried within a flexible tubular casing 26, which is wound and unwound upon a reel 27 located upon the deck of. a boat or tender above water, -the upper end oi the airsupply pipe 2 1 being eounel ted with a pipe 2h avhich pipe is in turn connected with branch pipes 29 and 30 communicating with a low pressure tank 31 and high pre re tank The exhaled air passes .t'rom within the armor 17 out throu h an opening therein communicating Witht .e attachment 522 from which it enters the tube 25, by which it is carried above water and discharged into the atmosphere. Suction tubes 33 are connected with the pump 18 and extend down within each leg sectionot the armor to the feet.

The operation of my improved valveis as tollo \\s:l\'hen the diver is below the water surface, air will be supplied to him from the low pressure tank 81 at slightly above atmospheric pressure. The air Wlll pass through the pipes 29 and 28., supply tube 24-, attachment 22, pipe 20, and enter the cup through the hub and tubular projection 15" on the cap 15, from whence it will escape through the openings 18, into the annular recess t and pass through the port .6 into the armor17,through the pipe or tubing 38 and spreader 4". These conditions will prevail unless there is leakage of water into the armor. when if it rises to an uncomfortable or dangerous height, the diver will signal by telephone: (with which 1 propose to equip the armor) when the attendant above will open the cock El i in the branch pipe lead- 45 ing from the high pressure tank 32 when the air will pass through-the same channels as from the low pressure tank 31, but owing to the high pressure when it enters the cup' 10, its force will overcome the tension of the spring 12, and force the cup down upon the rubber ring 9 in the shoulder 8 of the using 1 bringing the openings 14 in the cup within the annular recess a) in the casing 1, and in communication with the port' 7 therein, when the air willbe conveyed to the pump 18 through the coupling or connection 19 and start the pump. the cup 10, t'he' annular recess l and the port 6 will be closed, but while the pump is working the exhaust theretrom is dicchargel'l into the armor through asuitable spreader B5, and the diver is thereby supplied with air; When the pump is at work any water port ii.

.the high pressure is on.

in this position ot through a pipe 36 provided with a check valve 39. \Vhen the armor is freed from water, the diver will so inform the attendant above who will shut oil the hi; in pressure sir" ply, when the spring 12 Wlll expand and raise the cup 10 to the normal position, thus opening eonnnunication for the low pressure supply of air through the openings 13 and The cushion or rubber ring 9 prevents jar when the cup 10 is forced down and provides an el'astict seat for the same while It is preferable to provide a vent, hole 37in the bottom of a the casing '1 to avoid the possibility of a vacuum forming and retarding the operation of the cup 10.

The reel, the conveyer for the air tubes and the attachment for thesame to the armor, are all of peculiar construction, and form the subject matter of separate co-pending applications Serial Nos. 595,851; 595,811)
