ANTENNA FOR RADIOTRANSMISSION SYSTEMS. 7
Specification of Letters Patent. Patented He 20, 1922.
Application filed February 27, 1913, Serial No. 750,981. Renewed October 23, 1918. Serial No. 259,455.
To all whom it may concern:
Be it known that 1, JOHN HAYS HAM- MOND, J r., a citizen of the United States, residing at Gloucester, inthe State of Massachusetts, have invented certain new and useful. Improvements in Antennae for Radiotransmission Systems, of which the following is, a specification.
This invention relates to antennae, or aerial conductors, for the reception and transmission of radiant energy, and relates more particularly to antennae on vessels, where it is impossible to get a satisfactory length of antennae b the usual arrangement on torpedoes and 0t er vessels of small size,
and whereeven on large vessels the length and capacity of the antennae can be greatly and advantageously increased by my invention.
. In the accompanying drawings v Figure 1 shows my antenna attached to a tor edo or submarine boat.
igure 2 shows my antenna attached to the stern of a boat or other vessel.
Figure 3 is a side elevation of my antenna as attached to a battleship.
Figure 4 is a plan of my antenna as at: tached to a battleship.
In Figure 1, T is a torpedo or submarine boat, M is a hollow mast on said torpedo, A is an antenna, B is a towing line, is a towing anchor, F is a line for attaching the antenna Ato the torpedo or boat, I is an insulator between antenna A and line F, G
is a line for attaching the antenna A to the float C and the towing line B, G isa line between the float C and the towing anchor D, I is an insulator between the antenna A and the line Gr, L is a leading in wire from the antenna A to the receiving and transmitting apparatus K, and W is a winch for paying out or hauling in the antenna A and the towing line B.
' In Figure 2, S is a boat or other vessel,
N is a mast on said vessel, A is an antenna, F is a line for attaching the antenna A to the vessel, I is an insulator between antenna A and line F. B is a line between float C and the vessel S, which would act as a towing line when the vessel was under way. G is a line for attaching the antenna A to the float or buoy C and the line B, I is an insulator between the antenna A and the line G D is an anchor resting on the bottom, G is a line from the float or buoy C to the anchor D, L is a leading-in wire from the antenna A to the transmitting and receiving apparatus K, and W is a winch for paying out or hauling in the antenna A and the llne B. This arrangement shown in Figure 2 would be used when the vessel is at anchor,
tween the antenna wires and spreader R B is a towing line; W isa winch; Gr and G are lines connecting the spreader R and the towing line B with the float C Gr is a line connecting the float C with the towing anchor D and L is a leading-in wire from the antenna A to the receiving and transmitting apparatus K While a battleship has been used for illustration here, it is evident that my antenna can be used on any other kind of vessel.
The floats C and C and C are for the purpose of keeping the antennae out of the water, and for keeping the towing line near the surface of the water. The towing lines B, B and B kee the antennae steady and prevent the latter from varying their distance from the surface of the water too much. The towing anchors D, D and D are preferably in the form of a propeller running on a swivel, which arrangement helps to keep the propeller near'the surface of the water and the towing line and antenna nearly horizontal, when the Vessel is under way.
By this system of disposing my antenna, I can secure a far greater length and capacity of antenna than b methods heretofore in use on vessels, an the length of my antenna is not limited by the size of the connecting the antenna with the receiving and transmitting apparatus, and any suitable arrangementmay be used for winding up and letting out the antenna and the towing line, for keeping the outboard end of,
the towing line afloat and for other details of theconstruction; and in general I do not confine myself to the particular construction here shown, but changes and modifications within the knowledge of those skilled in the art, may be made in the construction shown and described herein, without departing from the spirit of my invention, provided the means set forth in the following claims be employed.
Having thus described my invention, I claim 1. An antenna for vessels for the emission and reception of radiant energy, one end of which antenna is attached to a vessel and the other end of which is attached to a towing anchor in such a manner that it shall be extended out from said vessel.
2. The combination with a vessel, of an antenna for the emission and reception of radiant energy secured to said vessel and adapted to be extended outwardly therefrom, a float secured to said antenna at a point spaced from the point of connection between said antenna and said vessel, an anchor, means connecting said anchor to said float, and a tow line connecting said float to said vessel.
3. The combination with a vessel, of an antenna for the emission and reception of radiant energy secured to said vessel and adapted to be extended outwardly therefrom, and a towing anchor secured to said antenna at a point spaced from the point of connection between said antenna and said vessel.
4. The combination with a vessel, of an antenna for the emission and reception of radiant energy secured to said vessel and extending outwardly therefrom, a marine float spaced from said vessel and connected to said antenna to hold said antenna in an extended position, towing means connecting said float to said vessel, and an anchor connected to said float.
5. The combination with a vessel, of an antenna for the emission and reception of radiantenergy secured to said vessel and extending outwardly therefrom, a float spaced from said vessel and connected to. said antenna to hold said antenna in an extended position, towingmeans connecting said float to said vessel, an anchor spaced from said float, and means connecting said anchor to said float.
6. The combination with a vessel, of an antenna for the emission and reception of radiant energy secured to said vessel and extending outwardly therefrom, afloat spaced from said vessel and connected to said antenna to hold said antenna in an ex tended position, towing means connecting said float to said vessel, an anchor spaced from said float, means connecting said anchor to said float, and means operative to simultaneously vary the effective lengths of said antenna and said towing means.
7. The combination of a Vessel adapted to float in a fluid medium, an antenna for the emission and reception 01' radiant energy secured to said vessel and arranged to be extended operably therefrom by the action of said medium thereon, and a towing anchor secured to said antenna at a point spaced apart from the point of connection between said antenna and said vessel.
8. The combination of a vessel adapted to float in a fluid medium, an antenna for the emission and reception of radiant energy secured to said vessel and arranged to be drawn outwardly therefrom by the action of said medium thereon, and a towing anchor secured to said antenna at a point spaced apart from the point of connection between said antenna and said vessel.
9. The combination of a vessel adapted to float in a fluid medium, an antenna for the emission and reception of radiant energy secured to said vessel and arranged to be drawn outwardly upon movement of the vessel through the medium, and a towing anchor secured to said :antenna at a point spaced apart' from the point of connection between said antenna and said vessel.
10. The combination of a movable body supported by a natural medium, a towing anchor, and means interconnecting the body and the towing anchor arranged for radiant energy signalling, and automaticall positioned upon movement of said body through the medium.
11. The combination of a marine body, a trailer, means interconnecting said body and trailer for radiant energy signalling, and towing means for said trailer.
12. The combination with a movable body movable through a surrounding medium and adapted to be controlled by radiant energy, of an extensible metallic means arranged for the reception of electromagnetic waves and arranged to be extended by movement of said body through the medium.
13. In a system for the control of a body movable through a natural medium by radiant energ', an extensible metallic means arranged for the reception of electromagnetic waves and arranged to be extended by movement of said body through the medium along the axis of travel "of said body.
