This invention relates to divin a paratus,

and more particularly to a 'vmg gear adapted to be worn by a diver for use in relatively shallow water where an expen- 5, sive, heavy, deep-water diving suit would be impracticable.

One object of this invention is to provide a diving apparatus of the above nature in which no float is needed to maintain the '10, upper end of the air tube above the surface of the water, the entire apparatus being carried by the diver." v

A further object is to provide an apparatus of the above nature having a rigid air tube which is adapted to remain vertical irrespective of whether the submerged diver is walking in an erect position or is lying or SWiIIImJDg horizontally.

A further object is to provide a diving apparatus of the above nature having safety means for preventing water from entering the top of the air tube in case the latter should become accidentally submerged.

A further object is to provide a diving 25 apparatus of the above nature having a drip rece tacle connected to the mouthpiece for receiving condensed moisture from the divers breath and any water which may leak into the apparatus. 30 A further object is to provide a diving apparatus of the above nature which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, 5 compact, and very eflicient and durable in use. 1 With these and other ob'ects in view there has been illustrated on t e accompanying drawings one form in which the invention may be conveniently embodied in practice.

In the drawings: Fig. 1 represents a vertical sectional view of the improved diving ap aratus.

Fig. 2 1s a side view the same, partly in section, and partly broken away. 45 Fig. 3 is a front view of the mouthpiece and the drip receptacle.

Fig. 4 is a side view, on a reduced scale, of the diving apparatus as it appears when worn by the submerged diver in an erect walking position.

I Fig. 5 is. a view similar to Fig. 4 showing the appearance of the apparatus when the submerged diver is in a horizontal swimming position.

Referring now to the drawings in which like reference numerals denote corresponding parts throu bout the several views, the numeral in icates' generally a rigid air tube which is adapted to remain vertical at all times. The air tube 10 comprises a air of

concentric pipes

11 and 12 connecte at their upper ends as by rivets 13, as shown in Fig. 1. The pipe 11v serves as an intake for a supply of fresh air from above the surface of the water, while the annular space between the

pipes

10 and 11 serves as an exhaust passage for the air exhaled from the diver. In order to cause the top of the tube 10. to

be automatically closed in case the latter is accidentally submerged, provision is made of a safety valve comprising a lever 14 pivoted on a horizontal pin 15 mounted in a collar 15a at the top of the outer tube 12, the inner end of said lever 14 having a circular closure member 16 adaptedto fit over the end of the tube 10, the outer end of said lever 14 being provided with a float 17 formed of any suitable material which is lighter than water, such as cork.

The pipe 12 is connected at its bottom, as by screw threads, to the upper-part of an intermediate chamber 18, which is adapted to surround the inner intake pipe 11. The chamber 18 has a pair of depending

rigid nipples

19 and 20 for receiving

flexible coupling members

21 and 22, the latter in turn bem adapted to detachably receive a pair of

exible tubes

23 and 24, .such as rubber, having interior coiled

springs

25 and 26 to prevent collapsing of said tubes under the water pressure. The outer ex tremities of the

flexible tubes

23 and 24 are adapted to detachably fit over a pair of

lateral pipes

27 and 28 extending from the side of a helmet chamber 29 which is preferably rectangular in shape, as shown in Fig. 3.

The inner end of the pipe 27 is located within the helmet chamber and is provided with a pivoted check valve disc 30 adapted to open inwardly into said helmet chamber for freel admitting fresh air thereinto when the iver inhales. The pipe 28 issimilarly provided adjacent its outer end with an outwardly-opening pivoted check valve disc 31 adapted to open when the diver is exhaling. By means of the above construction, it will be understood that the valve 30 will remain closedwhen the valve 31 is open and vice versa, so that no admixture of fresh and exhaled air will be possible.

In order to collect any moisture which may condense from the divers breath within a circular mouthpiece 32, or water which may leak into the air tubes or helmet chamber 29, provision is made of a drip receptacle 33, preferably rectangular in shape and having a pair of rigid strap members 34 adapted to fit over the divers belt 35. The drip receptacle 33 is connected, as by

flexible hose pipes

36 and 37 to short pipes 38 and 39 depending from the lateral intake pipe 27 and the bottom of the helmet chamber 29, respectively, as viewed in Figs. 2 and 3.

The mouthpiece 32 is adapted to be joined by any suitable air-tight connection to a flexible helmet 40 constructed of any suitable sheet material shaped to fit around the head of the diver. A pair of windows 41 are provided in the up er forward portion of said helmet 40 in Front of the position of the divers eyes.

In order to support the diving gear upon the divers body, provision is made of a U-shaped rod 42 adapted to be passed under the left arm of the diver immediately below the shoulder and supported in position with the arms vertical. The upper inner arm of the rod 42 is bent over at 43 andjournaled in a horizontal tube 44 mounted in the interior of the intermediate chamber 18. By means of this construction, the tube 10 and the apparatus associated therewith is permitted to pivot with respect to the U shaped rod 42 when the diver desires to change from erect to prone position, or vice versa.

The U-shaped rod 42 is adapted to be fastened to the belt 35 of the diver as by a strap 45 connected to the curved base of said rod and said belt by looped extremities 46 and 47, respectively. The rod 42 is also attached to the diver by means of a strap 48 which encircles about three-quarters of the divers body, and is likewise provided with end loops 49 and 50 fitted over the arms of said rod 42.

The rear end of the U-shaped rod 42 is connected by a thin resilient metal strip 51 to a collar member 52 slidable on the outside of the pipe 12. The strip 51 serves to prevent the tube 10 from tipping out of vertical position when the diver is lying or swimming in the horizontal osition shown in Fig. 5. An adjustable xed collar 53 is also located on the tube 12 below the slidable collar 51 to limit .the downward motion of the latter.

In order to hold the air tubelO vertical when the diver is standing erect or walking in a vertical osition,'provision is made of a vertical rod 54 detachably connected as by a clip member 55 to the inner arm of the U-shaped rod 42 and by a stri 56 to' a collar member 57 on the lower en of the pipe 12.

- Operation I In operation, when the diver wishes to go beneath the surface of the water in an erect or vertical position, he will first attach the apparatus upon his body in the position shown in Fig. 4 with the lower extremity of the rod 54 engaged in the clip 55. If-he desires to lie or swim in a horizontal position, it will be merely necessary for him to disengage the rod 54 from the clip 55 and bend his body down from the position shown in Fig. 4 to that shown in Fig. 5, the air tube 10 being maintained in a vertical position at all times.

In case the air tube 10 should accidentally become submerged, it will be understood that the float 17 will automatically swing from the dotted to the full line position shown in Fig. 2 closing the tube 10 and reventing water from entering therein. he diver will then immediately elevate himself until the upper end of the tube is again above the water surface, whereupon the safety valve on the air tube will open and permit the diver to continue breathing.

While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure but may be modified and embodied in various other forms without departing from its spirit.
