JAS. R. WORSTER, OF BALTIMORE,` MARYLAND.

DIVING-BELL.

Specification of Letters Patent No. 6,397, dated April 24, 1849.

To all 'wh-0m, t may concern.'

Be it known that I, J. RU'I'HnRiiwD` VoRs- TER, of the city of Baltimore, in the State of Maryland, have discovered and invented a new and useful mode andv apparatus for submarine explorations, called a stationary diving and exploring canopy, particularly adaptedto searching t-he beds of rivers and streams, for removing obstacles vto navigation and for` working where there is a current.

By this mode and apparatus, we can descend and return with great rapidity,l and most perfectV safety, or remain any length of time underwater, without inconvenience, retaining a perfect light by night or by day.

In order to enable others fto make and use my invention, I will proceed to describe its construction and operation, reference beinghad to the annexed drawings, they being a part of this specification.

Two Hat-boats E, are first constructed, about 30 feet long and 9 ft. wide, and from 2,1,- to 3 ft. deep, the sides of which, should be from 5 to 5%,- inches thick, in order to bear more Jfirmly, the superincumbent weight and for receiving large, iron bolts, E25 which pass through, into the cross-timbers, F next described. These flats are decked or planked over, and finished, in other respects, like other boats of that class. Across those iiats E are placed two pieces of timber F about 8 inches square, secured to the sides of the flats by four stout iron bolts, Q5 which pass up from the bottom, and secureto the top, by a screw forelock and tap 25; the flats E being placed the distance from each other required, and the timbers an equal distance apart, to leave an aperture, to admit thc. canopy 21 a free passage through. Between the last named cross-timbers F is inserted two inter-ties G, Fig. 5, of equal size, which run along the sides of the flats, E at rightangles with the cross-timbers, F and framed thereto. On this foundation is erected 4L double posts H and H about 20 ft. long. They are constructed of two pieces of timber H2 and Fig. 4f, the required length, 5 by 10 inches, the wide sides facing each other, and tied or framed together by timber W2, in such a manner, as to leave a lip X and X2 on the inside of the post H and H2 of about 4: inches, through which the sliding frame Z works up and down and is kept stationary. The tops of the posts H and H are framed together I, to correspond with the bottom, and secure stability, and thev posts, H and H2 are attached to thebed pieces F and F2 Vby substantial braces, J and 'to be employed, due allowance being made for the partwhich mustalways occupy the.

stationary frame, H and H2.

The sliding parts Z are tied, or framed together, by cross-timbers, K `and cross, or

reversed braces, K, suiiciently close to prevent springing and twisting, under the greatest pressure required.

In the bottom of the canopy, Fig. 5, there are two platforms, 12 which fall on a crossbar 16 each way, from the sides opposite, fixed by hinges, to the sides, and fastened by hooks to the same when they are raised up. The small canopy may be worked by pullies, 17 but, to the large size, the rack and pinion, U is applied, by placing the rack on the back part of the slides, Z2 and cutting a groove on the inside of the cross-ties, W and 72 any additional power may be applied.

Lamps t are placed on the sides of the canopy 21, in cast-iron boxes, L of suitable dimensions, screwed firmly over a clear glass V from -fl to 6 inches square, set in the sides, which throws the light in; and another glass t t is set in a metal screwsocket, inserted i-n an aperture, on the outside of the iron box, L which illuminates without. Out of the top of the box, L passes a tube m about one inch in diameter, to which, the smoke-pipe 7 and B B attaches, reaching to the top of the slides -Z. A small tube r, passes from the inside of the canopy to the inside of the iron box, L having a stop-cock s by which the stream of air is regulated, necessaryto sustain thelamps The oil is contained in a reservoir o on the inside, and suspended under a vacuum, by a stop-cock, P and conveyed by a curved tube, n into the lamp, t when required, by turning the stop-cock, P and allowing a portion of air to pass in, to force down the oil.

In the top of the canopy 21 is inserted a tube, 7 and B B in which is a valve g placed near each extreme, to which, the air-pumps, D are attached, by liXed B B and flexible a a joints. The air tube, 7 and B B is put on, by detached pieces, as the canopy 21 descends, and coupled to the outsideair-pump, D2 as it rests on the bottom, and again uncoupled, when about to be elevated, and readily adjusted to any depth ofwater. The communication with the outside, is through a' small tube, l1 which passes through the top of the canopy 21, a few inches, to which is attached a pieceof flexible tube 23 of sullicient length to reach the operators; on the end of which is a mouth-piece, 22 in which is a stop-cock 24.

Balls 19 are secured to one or more of the short cross-ties VW of the double posts H2 in such a manner, as to act against the pressure, upward and downward, as the slides Z lare moved.

l/Vhat I claim as my invention, and desire to secure by Letters Patent, is

l. The stationary mode of descent, by slides Z attached to the canopy 21 correspending in length to the depth of water,

and which slides Z pass through long, upright grooves, H and H2 attached to the Scows E, the slides Z and canopy 2l attached being forced down together by the rack and pinion l or other mechanical equivalents; the whole constructed substantially as herein described.

2. The'niode of supplying and using the light, by a lamp t secured to the sides of the canopy 21 having a chimney m passing out from the top, and a tube o" and stopcock s from the inside to admit a current of air of sufficient volume to sustain the lamps t with two glasses, one o of which throws the light inside and the other i "i out, the oil being kept in sufficient quantity in a holder 0 on the inside, suspended under a Vacuum and regulated by a stop-cock P.

3. For the novel Inode of communication, through a tube 11, reaching to the top of the slides Z with the mouth pieces 22 and stop-cocks 24: attached.
