Said cock C2 may be regulated so that and waterproof, and the second or outer shell the full supply of air (apart from that passing or easement is in communication with the through cock C)maybe turned into easement source of air-supply to the apparatus, so that B and thus tend to extend it telescopically, the said air-supply will assist the telescopic or connection maybe made, through said cock C2, between the air in shells A and B, so as to enable the shell B to be indrawn over the easement A. The pipe D is carried to the surface and provides an escape for the vitiated or surplus air in the easement A and at the same time forms a protector for the pipe C. ln the easement A are gages E and E', the former, E, for indicating the pressure of the water upon the apparatus and the latter, E, for indicating the pressure of air within the shell B.

ln the shell A is a dead-weight F, adapted to slide upon a rod F, held by stanehions or pillars F2. Said weight F is adapted to be easily shifted backward and forward, as may be required, by means of endless wire or rope F3, ruiming around pulleys Fl on the end of the stanehions. Aflixed to the end of the shell B and passing through female screw or nut G', afxed to the shell A, is a screw-shaft G, and passing through both the shells or casements A and B and through respective stuffing-boxes H2 and H3 thereon is a shaft or spindle Il, on the outer end of which is a screw or propeller H. The inner ends of the screw G and propeller shaft or spindle Il pass through and have bearings in a diagonal stay J. The outer end of this diagonal stay J has soles J which work in guides J2 upon the shell A, and this diagonal stay J forms a steadying-piece and guide in the relative movements of the shells or easements A and B. The inner ends of both the screw G and the shaft or spindle lil have square ends, on which will take a crank-handle, so that the requisite motion to propel the apparatus through the water backward and forward may be given to the propeller Il' and so that the necessary motion to extend or to indraw the shell or easement B over the shell or easement A may be given to the screw G. An air-tight and waterproof door B is provided in back end of the shell or easement A, so that, if desired, a communication maybe made between the interior of the respective easements A and 3 and so that the gland H3 and the bearing GiS may be lubricated and attended to as required.

lVhere necessary in the shell or easement A, and particularly in the front end, are ports or light-holes, those illustrated being` marked K, one above and one below the gripping or lifting appliances.

The lifting and operating appliances consist of an outer pipe or casting L, and it has a ball L seated exteriorly on the end of the nozzle-piece L2 and retained in such position by means of the pressure of the water upon an india-rubber envelop L3 pressing upon said casing L and prevented from actual contact therewith by conical spring L4, but forming a practically air-tight and waterproof joint around said casing or pipe L. In the ends, both inner and outer, of said casing L are stuffing-boxes or glands L5, taking around a pipe or outer handle M', surrounding rodhandle M.

The outer end of said pi pe-handle M terminates in a female thread or nut M2, through which passes the screwed end of the rod M. The inner end of said outer handle M terminates in stuffing-box or gland or other air-tight joint Ms and the operating-handle M4, while the rod M terminates in an operating-handle M5. On the outer end of the female thread or nut M2 are jointed the claws N, which may be of any desired shape and capacity. Passing through slot-s in said claws N are the ends Mj of T-piece on the outer end of rod or handle M. New by the manipulation of the two handles M'1 and M5 and the flexibility of the india-rubber cone L3 and spring LA1 the claws N maybe operated to pick up anything within reach of their length. Said claws il are drawn together and parted from one another by the revolution of the rod M in the female screw or nut M2, as is easily understood, extending orindrawing the end M of the rod M between the said claws N.

In operation the workers enter the casement A through door A2, which is then tightly fastened on top of dome or chest A. Then to sink the apparatus they open connection by three-way cock C2 between the easements A and B and then revolve screw G, so that the easement B will telescopically close upon easement A and reduce the displacement of the apparatus. \Vhen the weight overcomes thedisplacement,the apparatussinks. `\Vhen on the bottom or upon any wreckage or submarine workings, the operator regulates the set or inclination of the apparatus by manipulating the endless cord F3, so as to place the dead-weight F in such position as required. To regulate the quantity and pressure of the air-supply in the easement, the cock C is handled to requirements. To pick up pearl-shell or other objects, the handles M4 and M5 are operated as before described and the products or holdings of the claws N are released over a basket or receptacle (not shown) which depends from the overhead or above water working station. To move the apparatus backward or forward, the spindle Il is revolved by crank-handle and the propeller Il causes the desired alteration of position. To rise to the surface, the cock C2 makes connection of air-supply pipe C with interior of easement l5 and the screw G is revolved to extend the shell or easement B, and when the displacement becomes in excess of the weight the apparatus rises to the surface when the workers are released through door or cover A2.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. In diving apparatus of the class set forth the combination with a shell or easement containing the operators, of a second and telescopic outer shell or easement adapted to airtightly slide upon said first shell or easement IOO IOS

so as to reduce, or increase as the case may be, the displacement of the apparatus, substantially as herein described and explained.

2. In diving apparatus of the class set forth the combination With ashell or easement containing the operators, and having ports or lights therein, of aball-jointed casing forrods or handles, of claws or gripper sitting upon a nozzle-piece and held in place by a flexible cone, substantially as herein described and explained.

3. In diving apparatus of the class set forth, the combination of the telescopic shells or easements A B, the threaded shaft G passing through a nut G fixed in one end of the shell A and journaled in abearing fixed in the end of the shell B, a spindle H journaled in bearings in the ends of said shells and' in a diagonal stay J, and guides J2 in which said diagonal stay is movably seated, substantially as shown and described.

Dated this 8th day of September, 1896.

CARRICK PAUL.
