Definitions

  • the charges are delivered to the launching tubes by means of a loading tray which is up and down movable in the shaft between a discharge position and a position for loading depth charges upon the tray which is capable of receiving at least two charges at a time.
  • the installation further comprises a pair of compartmentalized magazines which are rotatable about axes parallel to the hoist shaft. The magazines and the compartments therein are so disposed that in predetermined angular positions of the magazines one compartment in each magazine is in alignment with the loading tray when in the loading position for transferring depth charges from the aligned compartments to the loading tray.
  • the present invention relates to a depth-charge launcher with an even number of launching tubes which can be elevated and possibly also traversed. More particularly, the invention relates to a launcher in which the longitudinal axes of the tubes are located in one and the same plane and in which, when the launcher is elevated 90, the launching tubes each form or can be traversed to form an extension of a loading hole in a base, for instance a deck, upon which the launcher is mounted. Such loading hole or opening is used to feed depth charges to the launching tubes with the aid of a hoist from a depth-charge magazine.
  • the hoist consists of, for instance, an endless chain mounting a hoisting tray upon which depth charges can be placed, the number of depth-charges corresponding to the number of launching tubes.
  • the depth-charge launcher can have all of its launching tubes loaded at one and the same time.
  • the hoist itself is encased in a hoist shaft, and the hoisting tray is provided with guiding members which are in contact with the hoist shaft, so that the hoisting tray in the hoist shaft is movable in one direction only.
  • the depth-charge launcher can have 2, 4, 6 etc. launching tubes. Four tubes have been found to be an appropriate number.
  • the problem with such depth-charge launchers is how to convey the necessary quantity of depth charges to the hoisting tray rapidly.
  • the problem has been solved in such a Way that two cylindrical revolving magazines are used, arranged on either side of the endless hoist chain in such a way that the cylindrical body surfaces of the revolving magazines come into contact with each other.
  • the two cylindrical revolving magazines are provided with an equal number of straight vertical compartments, which extend from the body surfaces of the magazines, and which are open at both ends.
  • the compartments have a direction which deviates from the radial direction.
  • the horizontal center line of the two compartments is beside the line which joins the vertical turning axes of the two cylindrical magazines.
  • compartments it is most appropriate to allow the compartments to be so deep that each of them can accommodate two depth charges, but it is, of course, also possible to have compartments for one depth charge, or for more than two.
  • the rotation of the two cylindrical revolving magazines is achieved by means of a common drive means, which is connected to the two magazines in such a way that, when turned, they rotate in opposite directions.
  • FIGS. 1 and 2 show the magazine part of a depth-charge launcher according to the present invention in two different stages of operation
  • FIG. 3 shows a plan of a magazine space for a depth-charge launcher, containing both the magazines according to the present invention and a store of depth charges.
  • 1 is a rectangular hoist shaft, extending from four loading openings or holes in a ships deck.
  • the hoisting tray is provided with guide members 5 and 6 at its ends, which are in contact with the walls of the hoist shaft, so that the hoisting tray cannot move in the hoist shaft other than in a vertical direction.
  • four depth charges, 7, 8, 9 and 10 are placed on the hoisting tray.
  • the hoisting tray 4 receives the four depth charges 7, 8, 9 and 10 from two mutually aligned and juxtaposed compartments 13 in two cylindrical revolving magazines 11 and 12.
  • the four depth charges 7, 8, 9 and 10 rest in the compartments with their ends on two supporting rails 14 and 15.
  • the compartments 13 are not disposed radially, but are set obliquely, as may .be clearly noted from FIG. 3.
  • FIG. 3 as previously mentioned, the two cylindrical revolving magazines are shown from above. Also a number of storage compartments 16, 17 and 18 are shown, which contain depth charges which with the aid of some appropriate transport member can be conveyed to empty magazine compartments in the cylindrical revolving magazines 11 and 12.
  • the hoisting tray 4 When four depth charges are to be transferred to the actual launcher, the hoisting tray 4 is first located below the bottom surface of the two cylindrical revolving magazines 11 and 12. Thereafter, the two magazines are turned so that two loaded compartments will be located in alignment with each other. The four depth charges are then located directly over the hoisting tray 4. If now the endless chain is set in motion, the four depth charges will be conveyed through the hoist shaft 1 up to the four launching tubes. When the depth charges have been fed into the launching tubes, the hoisting tray 4 is moved down again, so that it will be located below the bottom of the two revolving magazines 11 and 12. Thereafter, the two revolving magazines are turned so that two new filled compartments will be located in alignment with each other, so that their depth charges will be located directly over the hoisting tray 4. In this position, the hoist is ready to make a new loading movement.
  • An installation for loading launching tubes of a depth charge launcher comprising, in combination, a hoist means including a hoist shaft adapted to load depth charges into launching tubes; a loading tray adapted to receive thereon at least one pair of depth charges and transport means supporting said tray for moving the same up and down within said shaft to deliver depth charges to the launching tubes and to receive charges; and a pair of generally cylindrical magazines rotatable about their center axes, each of said magazines having in its peripheral wall a plurality of circumferentially spaced axially extending loading compartments for receiving therein at least one depth charge, the rotational axes of said magazines being mutually parallel and parallel to the lengthwise axis of said hoist shaft, said magazines and said compartments therein being spatially disposed so that in predetermined angular positions of said magazines in reference to each other one compartment in one magazine is in juxtaposition and alignment with one compartment in the other magazine and that both compartments are adjacent to the loading tray in the lowered position thereof for transferring depth charges from said aligned and juxtapos
  • each of said compartments defines an acute angle with a radial plane intersecting the respective compartments.
  • each of said compartments has a substantially rectangular transverse cross section, each two compartments in said aligned and juxtaposed positions defining a substantially rectangular outline in the direction transverse of the rotational axes of the magazines.
