A Harney Patented Nov. 11, 1941 UNITED STATES PATENT OFFICE j Application Febraryi This invention relates to af submarine forlaying mines, the general object of the invention being to provide means on the top of the submarine `for holding a mine,I with means for` releasing the mine when a person within the submarine desires so that thenne will pass upwardly and contact a ship which is` to be destroyed. i i

Another object of the invention is to provide magnetic means for holding the mine in position witha switch within the submarine for deenergizing the magnets topermit the mine to float from the submarine.` y

Another object of the invention is to provide a light indicator for indicating when the mine has left the submarine. l j j n A still further object of the invention is to provide means for propelling the submarine by man-power whenever desired, such as when the submarine is in the vicinityxof an enemy ship or the'like, thus making it impossible for the enemy to hear the motor which is ordinarily used for driving the submarine.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which: l

`Figure 1 is a side view of a submarine constructed in accordance with this invention.

Figure 2 is a top plan view of the submarine.

Figure 3 is a sectionon the line 3-3 of Figure 2.

Figure 4 is a section on the line 4 4 of Figure 3.

Figure 5 is an enlarged sectional view of the dome or turret part of the submarine and showing the mine heldin the concavity formed in the top of said dome.

Figure 6 is a sectional detail View showing the lamp indicating means.

Figure 7 is a diagrammatic view of the circuit. In these views the letter A indicates the body of the submarine which is provided with the dome or turret part I having the windows 2 therein and the deck of the submarine is provided with the usual hatches covered by the uidtight doors 3 and said submarine is provided with the usual periscope 4, the eye bolts 5 and other [z claims. (Q1. iii- 17) features which areusual with submarines. A propeller E` is driven from a motor M and a second propeller I is driven by a pedal device 8 carried by a frame 9 which resembles `the frame of a bicycle, the drivefrom the pedal device including chain and sprocket means IIJ and the gearing II. The frame carries a seat I2 for the operator and a rotary handle I3 is also carried by the frame and a link I4 connects the handle to the shank of a rudder I5. Thus the person occupying the seat I2 of the frame 9 can rotate the propeller 'I by the pedal device and at the same time control the movement of the submarine by means of the rudder I5. Of course, when the submarine is not in the presence of or ad- `jacent an enemys boat or other place where the enemy may be the submarine is run by the motor, the manual means only being used to `quietly operate the submarine without danger` of ,the

enemy detecting the noise of the operating parts thereof.

A battery B is also arranged in the submarine.

In carrying out the invention a semi-circular part I8 is formed in the top of the dome or turret I to form a seat for the mine I9 and a plurality l of magnetic devices 20 is located in the semicircular part in spaced relation and the upper ends of these devices are so formed as to contact parts of the mine placed in the semi-circular part so that when the magnetic devices are energized they will firmly hold the mine in place.

Figure 7 shows the conductors 2| of these magnetic devices connected to a switch 22 which hasone terminal connected to the battery B as shown at 23 and the other terminal of the switch is connected toJ the battery by a conductor 24. Thus by closing the switch current will be supplied to the magnetic devices to energize the same and by opening the switch the magnets will be deenergized and, of course, when this is done the mine will be released so` that it can float to the surface or against the bottom of a ship under which the submarine has been moved.

A lamp indicator is provided for indicating when the mine leaves the semi-circular part and said indicator includes a rod 26 slidably arranged in a tubular part 21 which depends from the bottom of the central portion of the semi-circular part IB with the rod 26 passing through the center magnetic device which is provided with a hole 28 for the passage of the rod. A lamp bulb 29 is carried by a socket at the lower end of the rod and conductors 30 lead from the lamp` and socket to the contacts 3| on the rod, the parts being insulated in any well known manner. A pair of contacts 32 is carried by the tubular member 2'I and when the mine is resting on the magnetic devices in the part I8 its weight engaging the upper end of the rod 26 will lower the rod to an extent where its contacts 3I will engage the contacts 32 and thus the circuit to the lamp bulb 29 will be closed, the contacts 32 being electrically connected to the battery by the conductors 34 as shown in Figure '7. When the mine leaves the part I8 springs 35 will raise the rod 26 and move the contacts 3l out of engagement with the contacts 32 and thus the circuit to the lamp 29 will be broken and this will indicate to those in the submarine that the mine has left the part I8.

Thus it will be seen that after a mine is placed in the part I8 and the switch 22 closed the magnetic devices will be energized and they will act to hold the mine in place. The weight of the mine will lower the rod 26 so as to close the circuit to the lamp 29. Then when the submarine comes in the vicinity of an enemy ship the motor M is stopped and one of the crew operates the pedal device 8 to turn the propeller 'I so as to move the submarine silently to a point under the ship. Then the switch is opened so as to deenergize the magnetic devices which results in releasing of the mine which floats up and strikes the bottom of the ship. This mine can be a magnetic one or of any other suitable type and should be provided with a time device for exploding it so that after it attaches itself to the shipv the submarine will have a chance of moving away from the ship before the mine explodes so that the submarine will not be injured by the explosion.

A supply of mines can, if desired, be carried in the submarine so that another mine can be placed in the part I8 after the rst mine has been released.

The submarine should be made of stainless steel or otherwise treated to eliminate any danger of a mine attaching itself to the submarine.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the claimed as new is:

1. A mine laying submarine comprising a housing extending upwardly from its deck, said housing having windows in its sides and a substantially semi-circular recess in its top, a plurality of magnetic devices connected with the wall of the recess and extending upwardly into the recess, said magnetic devices being spaced apart and having their upper ends of arcuate shape to form a substantially semi-circular seat for receiving a mine, a circuit for the magnetic devices and a switch in the submarine for controlling the circuit, the mine being released when the circuit is opened.

2. In a mine laying submarine having a housing extending upwardly from its deck and formed with a semi-circular recess in its top for receiving a mine, releasable means for holding the mine in the recess, a rod supported for sliding movement and having one end extending into the recess for engagement with the mine, a lamp at the lower end of the rod, a circuit for the lamp, spring means for moving the rod upwardly when the mine is released and means for opening the circuit when the rod moves upward lv under the action of the spring means.
