SAFETY-WEIGHT FOR SUBMARINE VESSELS.

Specification of Letters Patent.

Patented Aug. 6, 1912.

Application filed April 20, 1908. Serial No. 428,149.

To all whom it may concern:

Be it known that I, MAXIME ALFRED LAoBnUF, a citizen of the Republic of France, residing at Paris, in the Department of the Seine, France, have invented certain new and useful Improvements in SafetyWeights for Submarine Vessels, of which the following is a specification.

My present invention pertains to improvements in submarine vessels, and has reference more particularly to the arrangement and manipulation of safety weights.

The invention is illustrated in the annexed drawings, wherein:

Figure 1 is a longitudinal sectional view of a submarine vessel showing my invention applied thereto; Fig. 2 a vertical sectional view of a portion of the hull, showing the weight and the operating mechanism on a somewhat enlarged scale; Fig. 3 is a horizontal sectional view, taken on the line 3 3 of Fig. 2; Fig. 4 a diagrammatic view, showing a modified arrangement, whereby the weights may be released at any desired point or automatically released when the vessel has attained a predetermined depth; Fig. 5 a detail View showing a modified arrangement of the valve-actuating mechanism; and Fig. 6 a detail sectional view of the valve used in conjunction with the primary form of the apparatus.

The main object of the present invention is to provide a system of safety Weights which may be manipulated from a single point to instantly release either weight, or both, as occasion may require.

A further object of the invention is to provide, in conjunction with the manuallyoperated releasing mechanism, an automatically-operated releasing mechanism, which when the vessel has attained a predetermined depth will automatically release the weights. The arrangement of the weights in the hull is such that they may be released notwithstanding the fact that the vessel may be grounded or resting upon the bottom at the particular oint or points where the weight or Weig ts are located. The arrangement contemplates the use of at least two weights, one fore and the other aft, withmeans for releasing one or the other or a both of said wei hts.

nates the weight which is placed fore, and C the corresponding weight ilaced aft. A. pocket or recess D is formed 1n the hull for the reception of each weight, the pocket being of a height greater than that of the Weight and the weight-sustaining mechanism, which is locatcd'in the upper portion of the pocket. The pocket will be made in the form of a truncated cone or pyramid, and the weight will have the same general shape but will be somewhat smaller than the pocket, in order that when suspended within the pocket the bottom of the weight, may be at a point higher than the general line of the bottom of the hull. The weight is suspended above the bottom for the purpose of allowing said weight to be disengaged when the vessel is resting upon the ground in linewith the pockets in which the weight is located. The upper end of each weight is provided with a ring or eye E, into which passes the free end of a hook or L-shaped member F, the latter being secured upon or rigidly aftixed to a horizontally-disposed rocker-shaft G, which extends through a stuiling-box H, secured to one side wall of the pocket. The outer end of the shaft will by preference be supported in a hearin I (Fig. ,3), secured to that wall of the poc lret which is opposite the wall carrying the stutlingdoox. To the inner end of the shaft is secured an arm J, the free or outer end of the arm (when the weight is in its elevated position) extending beneath a pin or pistonrod K, which latter is secured to and movable with a piston L mounted in a cylinder M. So long as the piston-rod is projected out and extends over the arm J, as shown in the drawings, the weight will be held in its suspended position.

As will be seen upon reference to Fig. 1, there is a piston and cylinder for each weight, and pipes N N extend from the respective pistons to a valve mechanism 0, by which the admission of compressed air or other fluid under pressure from a pipe P to either of said pipes N or N is controlled. Said pipes discharge into the cylinders in front of the pistons, so that compressed air or other agent passing into the cylinders will force the pistons rearwardly and withdraw the rods K from over the arms J, thereby permitting the rocker-shafts to rotate and the weights to slip oil the hooks F. In Fig. 6 I- have shown a valve arrangement whereby either weight. may-be released, or

both released simultaneously. In said figure, P denotes apipe leading to a chamber P, exit from which to the pipes N, N is controlled by the two valves 1? a'ndI, normally held closed by springs. An actuating lever P fulcrumed .in a sliding block P underlies the downwardly-projecti11g valvestems, and by rocking it in one or the other direction, one or the other valve may be opened, as desired. By operating a screw P9, mounted in the yoke P of the valvecasing, lever P will be bodily raised, and both valves will be simultaneously opened, and as a consequence both weights likewise released. It is conceivable, of course, that separate valves may be employed to control the supply of compressed air to the two pylinders, but in order that-the apparatus may be under the control of the navigator the valves should be located ata single point. While a single weight only is shown at each end of the vessel, a plurality of weightsmay be employed at each end, but as this is mere duplication it is not deemed necessary to illustrate the same. The angle of inclination of the side walls of the pocket in which the weight is normally housed is such that when the weight is released it will pass out of the pocket under the action of gravity, this notwithstanding the fact that the vessel may be in an inclined position.

In Fig. 4 is illustrated a modified arrangement, under which the weights may be either released manually or automatically when the vessel has reached a predetermined depth. In said figure the weight and suspending means therefor are similar to those shown in the previous figures, and are designated by the same reference letters. Opening into the cylinder M at the lower end thereof to one side is a pipe N, con-' trolled by the valve 0, as in the former construction. A second pipe Q also opensinto the lower end of the cylinder, said pipe terminating in a valve-chamber R, in which is mounted a valve S that normally closes the port or passage leading to the pipe QQ Air or other fluid under pressure enters the valve-chamber through a pipe T, which may be a branch of the pipe'that conveys the compressed air to the pipe N. Valve S is mounted upon a stem U, provided wit-h a quick pitchthread V, which. works in a suitable bearing secured in the valve-casing. To the'outer end of the valve stem U is secured an arm W, which in turn is pivotally connected by alink WV to the lower end of the solenoid X of a magnet The winding of the magnet is included in a normally open circuit which may be c osed by a solenoi switch Z, whid h latter is in a normally open circuit A. Included in the circuit- A is a gage, co prising an adjustable contact member B, which may be set to any desired point upon the scale, and a neeformed in the vessel.-

a Bourdon tube D, to which is attached a rack F, said rack meshing with a pinion G made integral with or secured to an internal gear H, which in turn meshes with a pinion I, to which the needle is attached. The rack is held to the pinion by a roller J It will, of course, be understood that the pinion I Will-be insulated, so that until the needle 0 contacts with the member B the circuit A will be open. The contact member B may be adjusted to close the circuit at any predetermined point, and'as will be readily appreciated when the vessel reaches a given dept-h the needle will close the circuit A, thereby energizing the magnet E and actuating the solenoid switch Z to close the air-- cuit in which the magnet Y is located. A

relatively weak current is all that it is necessary to employ in conjunction with the gage and the magnet .E. A heavy current, however, will be passed through the line which controls the action of the magnet Y and its solenoid. The upward movement of the solenoid X will, through the connections hereinbefore described, rotate the valve-stem U and unseat the valve S, permitting air to pass through the pipe Q, and move the piston inwardly into the cylinder M. This will have the effect of releasing the weights in the manner here-inbefore described.

It will be readily appreciated that in so far as the connections for actuating the valive are concerned they may be changed without departing from the spirit of the present invention. For instance, in Fig. 5 the valve-stem is shown as provided with a worm-wheel F, actuated by a wormformed upon the end of the shaft G. ofa jmotor H.

Said motor will occupy the same relative position as the magnet Y and its solenoid,

which arein effect a motor. It will like- 'wise be understood that the pipe Q may be provided with a branch or lateralextending fro the weight located in the other pocket In so far as the generic invention is concerned, any means for releasing the weights instantly may be employed, though the arrangement s'hown will be found efiicacious in practice.
