TELEVISXQN MAST STABILIZER John W. Hetrick, Newport, Pa. Application June 30, 1954, Serial No. 449,493 2 Claims. (Qt. 189-314) ates to antenna it signals or the e present invention is to provide a staas which is designed to prevent sway- The invention rel to receive televisio An object of th bilizer for antenn ing and vibration.
Another object is to provide an antenn ted as a separate aecessor n or re-design of the ant bject is to provide an ante eption which prevents p tenna sway or undue moti cts and advant masts of the type used a stabilizer which may be moun y without involving modificati nna stabilizer for television rec icture breathing" caused by an ing parts thro Fig. 1 is an elevation 0 on an antenna mast.
'g. 2 is a plan view of the same.
' eneralized elevation of t on positioned on a VHF ughout the sev l f the present dev1ce in position on of the present device nna installation.
awings by distinguishing refe observed that the invention ent, spring-leaf 21 positioned on ssembly comy rectangular con- -point for added -type clamp 6 as ide, cylindrical, split ng 5. A helper or 'tion adjacent the ckles 8. The split-type clamp Patented Apr. 26, 1955 6 is tightened by means of bolt 9 and nut It The ends 1 of the main spring leaf 5' press against the antenna mast 12 as shown in Fig. 1. In Fig. 2 the clamp 6 is shown in two sections for easy assembly.
In use, three units are needed to form one assembly with the main leaf springs 5 being positioned within the clamp 6. The clamp 6 is tightened by means of bolt 9 and nut 10 after the three main leaf springs 5 have been positioned against the antenna mast 12. In instances wherein extra stabilization is needed auxiliary leaf springs 7 which are welded to the clamp 6 are positioned adjacent the main leaf springs 5 by means of spring shackles ese auxiliary leaf springs '7 are not needed with light weight installations. It is apparent that the present assembly positioned at a critical point along the extent of the mast 12 effectively prevents sway due to wind action without the use of guy wires or the like.
