AAAIAAAAAAAAA INVENTOR wf/Vaa/vf/ ATTORNEY Patented -Mar. 17., 1936 UNITED STATES PATENT OFFICE 10 Claims.

This invention relates to diving suits and has for its object the provision of an all-metal enclosing structure affording a maximum of protection during submersion, together with light.

ness of weight permitting easy mobility. The improved structure also has novel leg and arm joints whereby resistance to limb movements is minimized and great freedom of undersea operation is aiorded.

A further object of the invention is to provide means for articulating the various leg and arm joints to facilitate easy movement of the wearers limbs when the device is worn, at the same time preventing the possibility of leakage at the articulated joints. l

Another object of the invention is to provide improved grappling means for use in conjunction with the suit, which enables grappling operations to be conducted easily and expeditiously under water.

These and other objects are attained by the improved structure hereinafter described and more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawings forming a, part hereof, 1n which Fig. 1\ is a front elevation of a diving suit made in accordance with the invention; .Fig. 2 is a side elevation of the lower portion of the suit; Fig. 3 is a sectional view on the line 3-3 of Fig. 2, looking in the direction of the arrows; Fig. 4 is a sectional View on the line 4-4 of Fig. 1, looking in the direction of .the arrows, with the arm enclosure or sleeve swung slightly upward; Fig. 5 is a sectional view on the line 5-5 of Fig. 1, looking Vin the direction of the arrows; Fig. 6 is a sectional view through the elements shown in Fig. 5 with the parts in separated relationship; Fig. '1 is a vertical sectional view through the grappling device,. the view being taken on the line 'I-l of Fig. 8, looking in the direction of the arrows; Fig. 8 is a sectional view on the line 8-8 of Fig. 7, looking in the direction of the arrows; Fig. 9 is a sectional view through the grip or handle portion of the grappling mechanism; Fig. 10 is a View of the grappling hooks, with parts in section, showing the hooks in open position; and Fig. l1 is a sectional View through a modified arm enclosure or sleeve showing a flexible rubber enclosure member for the hand and greater portion cf the arm. p

With reference to Fig. 1 of the drawings,'5 indicates the upper member or body portion of the suit, said member being made of sheet or cast metal and having a dome shaped top provided with a projecting lug 6 formedv with an opening 1 for engagement by a line. member 5 is provided with a plurality of observation windows 8 which may be formed therein'in any suitable way common to this art. Said top member 5 is provided with arm openings 9 from which the arm enclosures or sleeve members II extend. Mountedin the arm hole 9 is an annulus or ring I in which the sleeve member II is mounted to move universally. Said sleeve member is provided with a rounded or ball-shaped inner end I2 pivoted on pins I3 in a ring I4 mounted for rotative movement within the outer ringv or annulus I0. To permit of easy rotary movement of the sleeve portion II and the ring I4 in which it is pivoted within ring I0, ball bearings are provided at I and I6, these bearings being maintained in position by means of 'the nut I1 threaded on the outside ofthe ring I4. A packing shown at I'Il prevents leakage between ring -I4 andthe outer ring Ill. Packing is also provided at I8 between the ball-shaped inner end I2 of the sleeve and the `inner surface of the ring I4, said packing being held in place by the nut I9.

From the arrangement described; it will be clear that a universally movable shoulder joint between the sleeve portion II and the upper body portion 5 of the suit is provided. The sleeve portion II may be composed of sheet or cast metal or other rigid material. At its outer end the sleeve portion I I is formed with a thickened annular terminal 20 and projecting laterally therefrom at diametrically opposite points are studs 2l (Fig. 4) on which links or plates 22 are pivoted, said links or plates being attached near their opposite ends to laterally extending lugs 23 provided on the forearm portion 24 of the sleeve, by the screws 21,5. Through this arrangement, the forearm portion 24 of the sleeve has al pivotal movement transversely of the longitudinal axis toA conform to the elbow movement of the arm. l To permit of a smooth pivotal movement of this kind, the inner portion of the forearm part 24 is made partly spherical as at 26, as clearly shown in Figs. 1 and 4. Packings 21 are disposed betweenthe outer face of the rounded part 26 and the inner surface of the part 2G to prevent y The top- 3| received in the projecting boss 32. A rubber glove 33 is secured on the end of the cuff part 28, said part being formed with a nipple-shaped extremity 34 to receive and securely hold the glove.

Through the arrangement described, each arm enclosure or sleeve is so jointed that the natural easy movements of the wearers arms are permitted. That is to say, the shoulder joint is provided with a universal movement; the elbow joint has a swinging movement; and the wrist joint has a freely rotative movement.

The connection between the top body portion 5 and the lower body portion 35 at about waistline level, is shown in detail in Figs. 5 and 6. It will be there seen that near its lower edge the top body portion 5 is provided with a laterally projecting annular flange 36 on its outer face and that the lower edge of the part 5 rests upon a rubber gasket or washer 31, located in an annular seat 38 formed on the upper edge of the lower body portion 35. Said lower portion is provided on its outer surface with a number of spaced, laterally extending lugs 39 which are adapted to be taken under by inwardly extending lugs 40 located on the inner face of a clamping ring 4| .which acts when in its operative position shown in Figs. 1 and 5, to clamp together the two body portions 5 and 35. A locking ring 42 threads into the clamping ring 4| and impinges against the upper surface of the flange 36 on the body portion 5. To prevent rotative movement of the clamping ring 4| while the locking ring 42 is being threaded into it, a pin.43 is extended through one of the lugs 40 into one of thelugs 39. To don the suit and then establish a water-tight connection between the lower body portion 35 and upper body portion 5, the wearer first steps into the lower body portion and the upper body portion 5 is then brought down to rest upon the packing or gasket 31. The clamping ring 4I is lowered to permit its lugs 40 to pass between the spaced lugs 39 and it is then turned slightly so that the lugs 48 are located directly below and take under the lugs 39. With the pin 43 then placed in position so that ring 4| is prevented from rotatingI and the locking ring 42 engaging the internal threads 44 on the clamping ring 4|, the locking ring 42 is then tightened down by a suitable tool engaging in the notches 45 on ring 42. The locking ring 42 is provided with a shoulder portion 46 which exerts downward pressure on the ange 36 and forces the lower edge of the upper or body portion 5 down hard upon the gasket or packing 31. With this arrangement, the two parts 5 and 35 of the body of the suit are tightly clamped together, yet are capable of quick separation by unthreading movement of ring 42 when it is desired to remove the suit.

In Figs. 1, 2 and 3, the construction of the leg portions of the suit are shown, and since both legs are similar in structure, a description of one will suiice for both. 'Ihe lower body portion 35 is provided with leg openings or sockets 41 and capable of pivotal movement therein is a nearly spherical portion 48. Said portion is provided with lateral projections 49 and attached to said projections by screws. 58 are links 5|, each of which is pivotally mounted near its upper end on the studs 52 fixed in and projecting from the annular laterally-projecting part 53 on the leg sockets 41. A packing 54 is interposed between the outer surface of the spherical part 48 and is held in position by a nut 55. Below the links 5| are a pair of links 55 which are attached by screws 56 to the part 49 on the upper leg member 48. The studs 51 pivotally receive the upper ends of links 58 winch are secured by screws 59 to projections 60 formed on intermediate leg member 6|, the upper end of this member 6| being connected by ball and socket joint to the lower end of the upper leg member 48. The wall portion of the joint is formed by the rounded member 62 on intermediate leg section 6| cooperating with a complementary shaped socket in the lower portion of the upper leg member 48. Packing 63 held in place by nut 64 prevents leakage between the ball-shaped member 62 and the socket in which it is mounted. Near its lower end, intermediate leg member 6| is provided with laterally projecting studs 65 over which links 66 extend, said links being rigidly attached to the part 6| by means of the screws 61. Studs 65 also pivotally receive the upper ends of links 68 which are secured by screws 69 ffl to projections 10 formed on the foot portion 1| y as, for example, the upper links 5| have a moverz.

ment forward limited by means of the angular shoulders 15. The knee joint has a limited movement reversely by means of the angular shoulder 16, and the ankle joint has a limited forward movement by means of shoulder 11. The entire method of articulation of the various leg enclosure parts are such that complete freedom of movement is afforded for the legs without the possibility of jamming or locking any of the leg joints.

In Fig. 4 the arm enclosure or sleeve is shown as being provided with a-short glove to cover 'the hand only. To afford greater arm action it may, in some cases, be found desirable to have the greater p'ortion of the arm of the wearer encased in a. glove. In such cases, the entire forearm and elbow can be enclosed in a lengthy glove, such as shown at in Fig. l1. The remainder of the arm enclosure, consisting of the shoulder part and upper arm is similar in all respects to that previously described and shown in Figs. 1 and 4.

In Figs. 7 to 10 inclusive, is shown a grappling device which is often found desirable in certain cases. Such device consists of the part 24 heretofore described, provided with the boss 32 in which a sleeve 8| is rotatively mounted on the ball bearings, 82, with suitable packing 83 interposed between the boss 32 and sleeve 8| to prevent leakage therebetween. Sleeve 8| is threaded in the upper end of a tube 84 and held in position within said tube is a cylindrical ratchet memberv 85. Mounted for vertical movement within the ratchet member is a yoke 86 in which is mounted a pair of dogs 81 which are normally spread apart by means of a spring 88 interposed between them.

'Ihe spring 88 normally tends to cause the toothed ends of the dogs 81 to be held in engagement with the toothed face of the ratchet 8,5. The dogs are enclosed in asleeve |08 and are movable through slots 69. in the arms of yoke 66. and each of said dogs carries a cam 90 having an inclined upper face adapted to be engaged by a correspondingly inclined cam surface 9| provided on a movable cross-bar 92 extending across the upper end of the yoke 86 and movable in the slots 89. This arrangement is such that when the wearer presses downwardly on the cross-bar- 92, cam surfaces 9| operating against the cams 90 will draw the two dogs 81 toward one another against the tension of the spring 88 to cause the dogs to be disengaged from the ratchet 85 so that the entire yoke including the dogs 81 is movable downwardly under pressure of a spring |00, as viewed in Figs. 7 and 8, the eiiect of this movement being to cause the jaws or hooks shown at 93 to spread apart or open as will be hereafter explained. The yoke 89 is connected'to a rod 94 slidable'through a closure plug 95 secured in the end of the tubular member 84 and through a stuiiing box 96 provided on plug 95. Within the tubularmember 84 the rod 94 is surrounded by a sleeve 91, said sleeve having its upper end closed by a cap 98 holding packings 99 in position. Coil spring |00 surrounding the rod 94 within the sleeve 91 exerts pressure against a collar |01 fixed on the rod. At its lower end, the rod 94 is secured to the cross-bar of a U-shaped bracket |02, movable within a yoke |03. Bracket |02 has a cross rod |04 (Fig. 10) passing through slots |05 in the ends of the jaws or hooks 93 and these jaws or hooks are pivoted at |06 in the diverging ends |01 of-yoke |03. This provides a toggle joint by which the jaws 93 are held in either the closed position shown in Fig. 7 or in the open position shown in Fig. 10. The operation of the grappling device is substantially as follows:

The handle portion, comprising the tubular enclosure |08, within which the dogs 81 slide, and the member 92 is gripped in the hand. When pressure is imposed on member 92 it is forced downwardly, or in a direction toward the jaws 93, which action causes the' dogs 81 to be drawn toward one another and released fromv their engagement with the ratchet 89, so that the yoke 80 and rod 94 attached thereto can be moved longitudinally ofthe tubular casing 84 by pressure of spring |00. As rod 94 is moved toward the jaws 93, it forces the jaws to move to open position, as shown in Fig. 10, by movement of the cross rod |04 in the slots |05 of the jaws. When the gripping pressure of the hand against member 92 is relaxed, dogs 81 engage ratchet 89 and as the yoke 8B is drawn upward the jaws will close as shown in Fig. 7 and will so remain until pressure on cross bar 92 again disengages dogs 81 .from the ratchet to enable spring |00 to function and open the jaws.

The structure of the suit is such that extreme lightness, consistent with requisite strength is provided and easy movement of the limbs during undersea operations is had.
