12 Claims.
This invention relates to airplanes, and particularly to an airplane carrying a boat which may be lowered from the body or fuselage to allow for descent of passengers or crew in normal operation or to allow escape in case of emergency or landing of troops or arms in case of war.
It is also an object of the invention to provide an improved construction inwhich the boat in normal operation of the plane is concealed in a compartment opening through the body or lower part of the fuselage and when so mounted closes and seals this opening, and the bottom of the boat forms a portion of the bottom of the fuselage.
It is a further object to provide improved means for mounting the boat and to raise and lower it in combination with an airplane having wings sufficient to support the plane with propellers for driving it in a horizontal position for normal operation, in combination with a relatively large lifting propeller having power means for driving it about a vertical axis and having sumcient lift so that the speed of the plane may be lowered sufficiently to permit lowering and launcmng of the boat while the plane is in night, and to permit take-ofi and landing of the plane itself in a small space where running room is limited.
With the foregoing and other objects in view I have devised a construction illustrated in the accompanying drawings forming a part of this specification, it being however understood I am not limited to the specific construction and arrangement shown but may employ various changes and modifications within the scope of the invention.
In these drawings:
Fig. l is a perspective view of a plane embodying my improvements and showing the boat bein owered therefrom;
is a transverse section through the body or fuselage and indicating how a boat may be mounted therein;
3 is a partial side elevation or partial longitudinal section of the fuselage showing a somewhat different arrangement of the boat and means for mounting it;
i is a transverse section of the body or fuselage of Fig. 3;
Fig. 5 is a partial section and elevation showing an improved lifting and lowering means for the boat;
6 is a detailed section of the bottom of the boat;
Fig. 7 is a side elevation of an improved type at winch drum;
Fig. 8 is a transverse section thereof substan-- tially on line 8-8 of Fig. I;
Fig. 10 is a partial elevation and partial section showing an improved cooperating means on the lifting rope or cable for detachably securing it to the winch drum.
The airplane shown comprises a longitudinal body or fuselage H, and extending from opposite sides thereof are lifting wings l2 preferably of sufficient span and width to support the plane in normal flight in horizontal direction, there being any suitable number of propellers l3 associated with these wings and driven by any suitable type or" motor for driving the plane in normal horizontal direction. Mounted above the body or fuselage is a relatively large lifting propeller rotating about an upright axis and also driven by any suitable motors, not shown, and it may be mounted on an upright column as described and claimed in my copending application executed and filed or even date herewith. It is preferred that this lifting propeller be of suflicient size and driven by sufflciently powerful motors to provide a large amount of lift for the plane, preferably suihcient lift so that the plane will remain in flight with very low horizontal motion to permit launching of a boat lowered from the plane on the water or raising of such a boat from the water while the plane is in flight and also to permit take-01f or landing of the plane in a relatively small space or from and on a short runway or where running room is limited. At the rear edges or the wings 52 are the usual ailerons l5, and other devices such as braking naps or auxiliary pontoons it may be provided on these wings. In the tail of the fuselage are the usual horizontal and vertical stabilizers ii and t8 together with the elevators i9 and rudder 28.
If desired the body or fuselage may be formed to carry large pontoons 2! given the general shape of boats on their under sides so that they,
may support the plane on the water, and these boats may have suitable engines, driving screw propellers for driving these pontoons on the water. They may also be provided with landing wheels 22 for landing and taking ofi on and from land, which wheels may be retractable into the bodies or not as desired. It the ship is to be used for war purposes these pontoons may have suitable torpedo tubes 23, and any desirable type of guns it may be mounted in various locations about the plane.
The detachable and removable boat is indicated showing somewhat diagrammatically a section of the fuselage, the detachable boat and the means for mounting and retaining it in the fuselage and the mechanism for lowering it from or raising it to its position in the fuselage.
In Fig. 2 the body or fuselage is shown as having in its lower part a compartment 26 opening through the lower part thereof in which the boat 25 is mounted. Surrounding the opening are inclined walls 21, and extending about the periphery or sides of the boat is a. resilient yieldable sealing means 28 of rubber or other suitable material. This may be mounted in any suitable way, but in the present case it is shown as mounted in a suitable recess or channel 29 extending around and adjacent the deck 30. When the boat is in position as shown in the compartment 26 this sealing means cooperates with the inclined walls 21 to seal and close the opening about the boat and make it water-tight. The top of the compartment 26 is formed by a deck or floor 3| of the body or fuselage, and it may have an elongated opening 32 through which projects the upright upper portion 33 of the cabin or super structure of the boat. Between this upper portion 33 and the lower deck 39 may be an upright portion 34 of the super structure wider than the upper portion 33 and connected therewith by horizontal deck portions 35, which when the boat is in position is at the under side of the floor 3|. 40
While the boat is mounted in the body or fuselage it forms a part thereof and furnishes accommodations in the body for passengers or crew or for freight or other cargo and supplies, there of course being provided suitable communicating doors and openings between the interior of the boat and the interior proper of the plane. It will be seen in Fig. 2 that the lower outside walls of the boat form general continuations of the walls of the body.
Suitable means are provided for retaining the boat in position and these means may also be used for raising the boat to and lowering it from th body of the plane. If however it is desired not to rely wholly on this raising and lowering means for retaining the boat in position, additional means may be provided for securing and locking the boat to the lower side walls of the plane body.
the periphery of the boat in the side walls thereof A supporting and raising and lowering means shown comprises suitable tackle 36 including suitable hook members 31 having hooked ends seating in suitable sockets 38 in the super structure of the boat. They may be retained therein by a transverse rod 39 extending through the members 31 and retaining them against separation. The members 31 have additional hooks or eyes 40 supported in suitable links 4| in a block 42 suspended by a suitable cable 43. This cable may run over suitable pulley 44 to support it from 7 any suitable supporting structure 45 of the body of the plane. The other portion of the cable 43a is carried down into the boat to a winch 46 either driven by a power motor or by hand cranks operpresent case it i shown operated by a motor 41 operatin through gearing 48 to drive the drum: 49 of the winch to wind or unwind the cable 43 in the raising and lowering operations, and when th boat is in position in the compartment 24 the drum is locked against movement to retain it therein. It will be understood the raising and lowering means may be reversed with the winch and its operating means mounted in the body or fuselage of the plane instead of on the boat.
It is desired that each end of the rope or cable be secured so that there is no danger of its being accidentally or inadvertently disconnected. However, it is also necessary that it may be readily disconnected from the boat after the boat has been lowered so as to release it entirely from any connection with the plane. Thus in the upper tackle connection 36, by removing the stop pin 66 and withdrawing the bar 39, the hooks 31 may be readily removed from the sockets and thus disconnected from the boat. The other end 01' the cable may be readily disconnected from the winch drum 49. This drum is hollow and has an opening 5| leading to the space within the drum and a narrow slot 52 leading longitudinally from this opening. Secured to the end of the cable is a ball 53 of metal or other suitable material, or a large knot could be provided in the cable. This is inserted through the opening 5| and then the cable drawn laterally into the slot 52 so that the ball or knot is under this slot as shown in dotted lines Fig. '1 and in Fig. 8. As the ball or knot is larger than the width of the slot the cable cannot be withdrawn from the slot by a pull outwardly on it, but by sliding the cable and the knot or ball back into the opening 5i it may be withdrawn through this opening and the cable readily disconnected from the drum.
It is preferred that the bottom of the boat be provided with some means for cushioning the shock of landing, particularly if the landing is made on solid ground. For this purpose it is formed with a false or moveable bottom 54 below the real bottom 55 and spaced therefrom. Between the two bottoms are a series of coil springs 56 tending to separate the bottoms. A portion of these springs is mounted on bolts 51 secured to the bottom 55 and passing through openings in the bottom 54 and on which this bottom is slidable so that it may move toward and from the bottom 55, the outward movement however bein limited by the heads 58 on the bolts. As this bottom hits the ground or water it will yield upwardly against the action of the springs thus cushioning the blow on the bottom of the boat. The space between th two bottoms may be closed and sealed by any suitable means, such as a flexible rubber strip 59 or other suitable means secured to the two bottoms. Also to facilitate landing. as on solid ground or facilitate drawing the boat onto a beach or dock, the boat may be provided with retractible landing wheels 60 and may also have small wheels or rollers 6| mounted on the under surface.
If it is desired to launch the boat the speed of th plane is reduced to a desired amount and then the boat lowered by means of the winches 46 and cables 43. Any number of cables and winches may be provided as i found desirable or necessary. After lowering the boat to the water the cables may be readily disconnected from the boat by disconnecting the tackle 36 and disconnecting the cable from the winch drum. As the boat is lowered it is desirable that the opening 32 in the ating through suitable reducing gearing. In the floor or deck 3| be closed to prevent anyone falling through. For this purpose a pair of doors 62 may be provided each hinged at 63, one at each side of the opening. They may be lowered by suitable lowering mechanism or they may be mounted to normally be slightly inclined and lean against the structure 33 so that as the boat is lowered they automatically follow down with it thus closing the opening, the edges of the doors of course being provided with suitable notches or recesses for the cables 43. The edges may also be rabbetted as shown at 62a so as to overlap and make a tight closure. Such doors could also automatically be opened by the boat as it is raised into the body.
The construction shown in Figs. 3 and 4 is slightly different, although the same principle is involved as in Fig. 2, and the main structure is substantially the same. In this case the side walls of the body H are extended upwardly and inwardly on an incline as indicated at 63 and then substantially horizontally at their upper edge below the floor or deck 66 of the body to thus provide the opening from the compartment 63a in which the boat 65 is mounted. The rim of this boat is also provided with a flexible and resilient seal 66 corresponding to the seal 28 of the first form extending about the periphery or edge of the deck 61 of the boat, and when the boat is in position it cooperates with the inclined walls 63 to close and seal the opening from the compartment. This seal is also mounted in a recess or channel 68 in the periphery of the boat. The super structure 69 projects up through the opening E in the fioor BE and free communication is had between the boat and the interior of the body the same as described in connection with the form of Fig. 2. This boat is suspended and raised and lowered by the same mechanism as described in connection with Fig. 2 including the tackle 38, the winch 66 and the cable 53. The bottom of the boat may be provided with the same false cushioning bottom 54 as in the first form and provided with landing rollers BI, and the boat may be provided with the same retractible landing wheels 60. The opening in the floor 64 may be closed when the boat is lowered in a manner similar to that described in connection with the opening 32 in the first form. Here a pair of doors H may be hinged to the floor 64 at opposite sides of the opening 10 as indicated at 12 and normally inclined inwardly to rest on the super structure of the boat. As the boat is lowered they will automatically follow down with it and close the opening 10, or if preferred they may be provided with suitable raising and lowering mechanism.
