To all whom it may concern:

Be it known that I, ADOLF GRAF VON BUoN- ACCORSI DI PISTOJA, a subject of the Emperor of Austria-Hungary, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Self- Propelling Torpedoes, (for which I have obtained Letters Patent-in Austria-Hungary, No. 8,093 and No. 21,102, dated June 26, 1888; in Germany, No. 19,123, dated February 21, 1888; inFrance,No.188,915,dated February21,1888; in Belgium,No. 81,003, dated March 12, 1888; in Italy, Vol. XXII, No. 23,135, and Vol. XLV, No. 131, dated March 31, 1888; in Spain, No. 8,035, dated June 30, 1888; in Portugal, No. 1,211, dated May 17, 1888; in England, No. 1,297, dated March 20, 1888, and in Norway, N0. 931, dated May 28, 1888;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and

to letters or figures of reference marked thereon, which form a part of this specification.

Referring to the drawings, Figure 1 is a longitudinal axial and more or less schematic View of a torpedo embodying my invention. Fig. 2 is a vertical axial section of the chamber immediately in rear of the compressedair chamber, showing the mechanism that controls the admission-valve. Fig. 3 is alike View of the two stern-chambers immediatelyin rear of the ballast or sinking chamber. Fig.1 is a horizontal section of the chamber immediately in rear of the ballast-chamber, containing the mechanism for operating the sinking-valves. Fig. 5 is a section on line so 00 of Fig. 1. Fig. 6 is a vertical axial section of the rear end of the torpedo, showing the rudders and propellers. Fig. 7 is a like view, on an enlarged scale, a portion of the propellers and the vertical rudder being broken away. Figs. 8 and 9 are sections of the propeller and immersingrudder shaft and its bearing and the compressed air-distributing pipe, showing the ports thereof through which the air is ad mitted to the propellers.

The invention relates to self-propelling, offensive or fish torpedoes, and has for its 0bj ect to provide means for automatically sinking the torpedo should it miss its mark.

In my application for Letters Patent of the United States, filed November 15, 1888, Serial No. 290,966, I. have described a novel means for propelling a torpedo of the class referred to, in which the compressed air is caused to act directly upon the propeller-blades, the propeller operating on the principle of the Barker reaction wheel, whereby I am enabled to dispense with the usual piston cylinder and connections and other mechanism employed-for instance, in the Whitehead and other torpedoess0 that I am enabled to use a plurality of sinking-valves instead of one, as is the case in the WVhitehead torpedo, thereby expediting the sinking of the torpedo in case it misses its mark.

To. these ends the invention consists in novel means for automatically operating the sinking-valves and in a time mechanism for controlling the said means, substantially as hereinafter fully described, and as pointed out in the claims.

In the choice of the outlines of the improved torpedo it is the aim to preserve that form which presents the least resistance to its motion through the water and has the least tendency to the formation of eddies, and at the same time to give to the compressed-air chamber a perfectly symmetrical form and to locate the same as near the bow or head of the torpedo as possible, thereby reducing the labor and cost of the construction of the airchamber and facilitating the distribution of the weight of the entire structure and its contained mechanism, so that the persistence of the torpedo in its course through the water, which depends chiefly upon a perfect equilibration or distribution of weight, is materially increased.

In order that this part of my invention may be thoroughly understood, it will be necessary to briefly describe the propelling mechanism and the air-distribution. The motive fluid, preferably air, is compressed to form seventy to ninety atmospheres within a cylindrical reservoir or chamber K, having dome-shaped heads or ends 70 70 Fig. 1. To the head is connected the distributingpipe 2, and to said pipe is pivotally connected a pipe 19 by means of a suitable coupling p as shown and described in my application for patent hereinbefore referred to so that said pipe 19 may be revolved, for purposes hcreinafter described. To the pipe 19 is coupled a pipe p, and said pipes z, 39 and p constitute the distributing-pipe for the compressed air, the pipe 19 also serving as a support or bearing for the tubular propeller-shaft 61, mounted and movable endwise on said pipe. On the tubular shaft q are loosely mounted two screw-propellers A and B, Figs. 6 and 7, said propellers having their blades curved in reverse directions, the blades of the propeller A being, for instance, segments of a righthand screw-thread, while those of the propeller B are segments of a left-hand screwthread. In the hub of each propeller is formed an axial chamber A B, respectively, that have the form of a truncated cone in longitudinal section, said chambers tapering rearwa'rdly, and through which the hollow shaft q extends. The compressed air is admitted to the chambers A B through ports p p and q Q2, formed, respectively, in the pipesp and q, the ports 19 and q and p and g registering with each other. The object in pivotally connecting the pipe 13 to the pipez is to permit of its being revolved within pipe q, so as to adjust the area of the distributing-ports, and thereby the speed of the propellers.

It Will be seen by an inspection of Figs. 8 and 9 that by a partial rotation of the head 19 of pipe p (shown in' dotted lines and in full lines in Figs. 3 and 4) in the direction of arrow 1, the ports q in pipe q will cease to register, the air being cut off from the propellerchamber B, while the ports will still fully register with the ports 19 thus applying the full motive power to the propeller A. A partial rotation of the pipe 19 in a reverse-direction, or that of arrow 2,will produce a reverse result. The chambers A B perform here the function of auxiliary reservoirs, and jointly with the admission-ports and the moment of inertia of the revolving propellers regulate the speed of the torpedo, the air passing out through passages A B formed, respective1y,in the blades of the propellers A and B, the operation of which is based upon the principles of the Barker reaction-wheel, as fully described in my application hereinbefore referred to.

In order to permit of the adjustment of the ports referred to after the torpedo is completed, I provide a suitable slot 19 formed in preferably employ, but do not claim herein,

the means described and shown and claimed in an application for patent filed November 15, 1888, Serial No. 290,968, and in said application I have shown and described means for automatically cutting off the supply of compressed air to said distributing-pipe, said means being combined 'with a time mechanism controlled by the propeller A, and consisting, essentially, of a valve-operating 'lever L, connected by a rod L with a springactuated sleeve or cylinder n, encompassing the supply pipe and propeller shaft and mounted and sliding on a boss formed on the partition 76*, to which is screwed the tubular bearing 70 for the shaft (1 and pipe 19, to the outer end of which bearing is screwed onehalf of the coupling-head 19 for the pipes p (See Fig. 4.) The sleeve n is held in its normal position by a stop-lever n whose outer end lies in the path of a pin 29, projecting from the timing and registering gearwheel that meshes with a pinion t? on the arbor of the worm-wheel A, which latter meshes with a Worm-thread a on the hub of the propeller A, as shown in Fig. 3.

The mechanism for operating't-he sinkingvalve is controlled by the sleeve 41; hence it is timed to operate synchronously with the cut-off mechanism.

V V are the sinking-valves, having their seats formed in the partition or rear head K of the sinking or ballast chamber is, astern of the chamber containing the mechanism for operating the admission-valve. These sinking-valves are in communication with the outer water through the opening 19 in the shell of the torpedo, and which opens into the sinking-chamber, whereby the latter is always filled with water. This outside water communication, however, may be made through the openin g 29 as shownin Fig. 4. The valves V V are held to their seats by means of springs i2 and are connected with the spring-actuated sleeve 4?. by means of tubular rods '0 and rods '0, which latter have a slight independent motion within the tubular rods Q), so that during the first portion of the rearward movement of the sleeve 01. the rods 12 will move independently of the rods 0, and then with said rods to fully move the valves V'off their seats, which latter corresponds to the closure of the cut-off valves, so that both the cut-off valves and the sinking-valves will operate simultaneously. This is desirablein fact, necessary-in order that the course of the torpedo may be arrested and the torpedo simultaneously sunk, for if the sinking-Valves were to operate after the cut-off valve the torpedo would necessarily travel a distance correspending with the interval between the operation of' said valves, while if the cut-cit .valve were to operate sooner than the sinkin g-valves the torpedo would be liable to drift or rise to the surface.

The object of the simultaneous operation of the valves is to afford a means-for locating the torpedo and finding it again, and to prevent its destruction by an enemy should it miss its mark.

Inasmuch as itis not desired to sink the torpedo except when actually used for offensive purposes, it is necessary for torpedo practice to provide means for maintainingthe valves on their seats, and this is effected by disconnecting the valve-operatin g rods '2: from theactuating-tube 'n, in the following-manner: The connecting-rods o v are guided in rings 11?, formed at the end of arms of ashifting-fork n, pivotally connected with a screw n that works in a boss a, secured to the torpedo-shell, said screw being provided with a squared head projectinginto the enlarged bore of the boss, and so as to be accessible from the outside. By rotating the screw in the proper direction the rods on are lifted, being hooked to the valve-heads, their hooked ends a being thus lifted out of the eyes 92 secured to said heads, thereby disconnecting the valves from their operating-rods. It will of course be understood that the ambient water has free access to the chamber contain-- ing the; sinking-valve-operating mechanism through suitable ports in the shell of said chamber.
