Description
C. T. MASON May 14, 1940i ANTENNA MAST Filed Aug. 29, 1938 Patented May 14, 1940 UNITED STATES PATENT OFFICE 1 Claim.
My invention relates to an antenna mast, for use particularly in receiving and transmitting radio signals, and has particular reference to a sectional antenna mast which when erected may be used in a variety of places for both receiving and sending purposes.
Another object of my invention is the provision of an antenna mast comprising a plurality of sections of non-conducting material, such as wood or the like, with suitable members for connecting these sections in end-to-end relation with each other, with a channel in the side of the various sections within which an antenna is mounted, the antenna preferably extending from the top substantially to the bottom or base of the radio mast.
Another and further object of my invention is the provision of an antenna mast Which may be mounted in a large variety of places, such as on the roofs of buildings with a special socket member being provided for the purpose if the mast is mounted directly on the building; upon automobiles and other moving vehicles by means of a socket provided for that purpose; or upon the ground or upon at top buildings by means of a proper base provided for that purpose, or directly in the ground by driving a suitable tubular member having a point thereon directly into the ground and mounting the mast thereon.
In the use of radio masts for receiving and transmitting purposes, the all metallic mast has become in common use but the commercial handling of these devices is difficult, particularly for shipping purposes either by mail or express, and in these jointed masts the joints become loose and noisy, resulting in noise being picked up by the antenna and transmitted to the receiving set, and miscellaneous other dilculties which prevent the mast now in use from giving complete satisfaction. In my improved mast, these diiculties are overcome. There is no noise produced by the movement of the'various sections of the antenna which can be transmitted into the radio receiving sets or upon th-e sending Waves.
Another and further object of my invention is the provision of a radiomast Which can be made in various sizes, dimensions and lengths for use in a variety of purposes and Which can be packed for shipment and transmission in a comparatively small area and assembled by the user or erector of the radio set in a variety of places and positions to be determined by the necessities or desires of the operator.
These and other objects of my invention will be more fully and better understood by reference (Cl. Z50-33) to the accompanying sheet of drawings, in Which- Figure 1 is an elevational view of my improved antenna mast mounted in a base;
Figure 2 is a vertical view of a mast mounted 5 for insertion directly into the ground;
Figure 3 is a detailed elevational view of the various parts of the sections making up the mast; Figure 4 is a view partially in elevation and partially in section of a mounted member for use 10 in mounting the mast in the ground, with a lightning arrester at the top of the base member; and Figure 5 is a View of `a modified form of base mounting member for mounting the mast in the ground. 15
Referring now specifically to the drawing, and in Which like reference characters refer to like parts throughout, the mast I0 is shown mounted in a base II, the mast I0 being held by brackets I2 inserted in the base member II adapted to 20 receive the base of the mast IB. The mast I 0 `is made up of a plurality of sections I3, I3 made I of wood or some other suitable nonconducting material, and held in end-to-end relation with each other b-y means of ferrules Ill, I4 into which 25 the ends of the members I3 extend so that the continuous mast, such as I0, is formedby placing together these sections, particularly as shown in detail in Figure 3. Each of the sections I3 has a channel I5 extending longitudinally there- 30 of, the channels I5 being adapted, when thesections I3 are assembled, to be in register and to have an antenna I6 extending longitudinally thereof, the antenna being lxedly mounted in a ball I 'I mounted at the upper end of the mast 35 Il! and vat the endv of the topmost section I3 with a small f-errule I8 being positioned around the end of the topmost section I3 to hold the antenna IG in a position in the mast I0 and to protect the end of the topmost section I3.
In the lowermost section, a pair of transverse holes I9 and 20 are provided so that in placing the antenna I6 in position it is threaded down from the top in the channels I5 and under the ferrules I4, and placed transversely through the 45 hole I9 and back through the hole 20, with the free end being provided for attachment to the radio receiving or sending apparatus as may be desired. The antenna is preferably made of braided or woven strands of wire, fabric or other- 50 Wise covered if desired, which of course is eXib-le and can be threaded through these openings, and When drawn taut in the channel I5 and threaded through these openings, I 9 and 20, is held in fixed position with respect to the mast I0.
Cil
For the purpose of mounting the mast I`in the ground in one form, a section of pipe 2| is shown having a pointed end member 22 inserted therein, on the upper end of which a socket member 23 is provided, within which the bracket members I2, I2 may be positioned, a clamping screw 24 being provided extending through the side wall of the member 23 and providing means by which the base of the radio mast I0 is clamped between the members I2 mounted in the socket 23. An extension 25 of the member 23 is adapted to t over the section of pipe 2I with a screw 26 extending therethrough, which holds the member 25 in engagement with the section of pipe 2I and also provides means for the attachment of a ground connection from the radio receiving set, if such may be desired.
In case it is desired to lengthen the pipe, a
A further form of the mounting of the device in the ground is shown in Figure 5, wherein a socket member 29 is provided which is internally threaded at its lower end and is threaded to another section of pipe 30 having a screw 3| in the walls thereon to provide ground connection, with the point 22 being provided so that the device may be driven or otherwise placed in the ground to hold the mast IIJ in position, the lower end of which is inserted into the socket 29 so that it is held in vertical position with the antenna IB extending in the sides thereof as shown and described heretofore.
'I'he erection and operation of the device will be readily understood in that the sections I3 are jointed together by inserting into the ferrule I4, with the antenna I6 being rst placed in position in the topmost section I3 and drawn taut, and inserting the ferrule I4 into the channel of the second section I3, with the antenna in each instance inserted underneath the ferrules I4 until the bottom is reached, when it is threaded through the lowermost section as heretofore described. The mast IIJ may then be inserted in the base member II through the medium of the bracket member I2 and set upon a flat roof or flat ground, the base II being of suicientl breadth and width to prevent the mast from overturning or from being blown over by the wind. The radio receiving set may then be connected to the antenna I6 as desired, and for purpose of sending the tapping off the sending antenna may be made at various points intermediate the length of the antenna I6 to provide for various sending wave lengths.
In case the device is to be driven into the ground, the base members are first placed in positiony and the lower end of the mast inserted in the sockets provided therefor, which will be suiiiciently strong to hold the mast in the vertical position desired when the base members are driven or otherwise placed in the ground.
While I have described more or less precisely7 the details of construction, I do not wish to be understood as limiting myself thereto, as I con template changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention.
I claim:
A radio antenna mast comprising in combination a plurality of elongated non-conducting sections, each of said sections having a continuous channel in its outer face extending from end to end thereof, tubular ferrules tted overthe ends of adjacent sections whereby the sections are held in end-to-end relationship with each other, a conducting, non-rigid antenna znembei extending longitudinally of said mast in said channels, the ferrules enclosing the antenna member, a conductive anchor member to which an end of the antenna is secured at the upper end oi the top mast section, and means for anchoring the lower portion of the non-rigid antenna member to the lower mast section,
CARL T. MASON.
