H. M. BROWN ANTENNA Filed May 29, 1926 Patented Sept. 11, 1928.

"UNITED, .sTATEs HAROLD M. BROWN, 01 ELMHURS'I, ILLINOIS.

'ANTENNA.

Application filed May 29,

My invention relates to anantenna, and the main object of the invention is to prov idean antennafor .a' radio and the like which may beused either outside of the building as an aerial, or inside of a building or a room, and in connection with a radio receiving set, said antenna being constructed in a very compact and durable form. Another object is to provide a compact antenna including a staff of insulating material and having insulated wire wound, thereon. A further object is to provide an antenna including a stafi of insulating materialhaving a bore therein extending to one end, and having said'end arranged to be mounted in a supporting bracket, while insulated wirev iswound on said staff and a part of said wire extends through said bore and emerges from said end for convenient attachment to a radio receiving wire.

Other objects and advantageous ends are accomplished with my invention, as will become apparent from the following description taken in connection with the accompanying drawing, in which:

Fig. 1 is an elevation, partly in section, illustrating one form of my improved antenna and being arranged in the shape of .an aerial mounted on the outside of a build- Figs. 2 and 3 are enlarged longitudinal and cross-sectional views respectively on lines 22 and .33 of Fig. 1;

Fig. 41 is a diagrammatic view of theWiring with its balanced winding used in this form of invention;

Fig. 5 is an elevation, partly in section, of a modified form adapted for use within a building and mountable on a dresser or a cabinet; 1

Fig. 6 is a diagrammatic view of the wiring used in this form of antenna;

Fig. 7 is a plan view of another modified form of antenna, arranged for mounting it within the radio box or cabinet;

Fig. 8 is a diagrammatic view of the wiring'used in this form ofantenna; and

Fig. 9 is an enlarged cross section on line 99 of Fig. 7.

The antenna, broadly, includes a staff of insulating material, such as wood, compressed rubber or fibre, bamboo, and the like, which is sufliciently rigid and durable for the purpose. The staff in each case has at' least one end arranged to bemounted in a bracket or socket and has a bore extending shown) 1926. seriaiNo. 112,508.

through said en dinto .the staff, and an insulated wire is wound on said staff and extends partly through said bore and through said end to be connected to conducting means, as a radio receiving wire,' leading,

from the antenna to the radioreceiving set.

The form of invention shown in Figs. 1- to inclusive compr ses a staifof insulating,

material including a shank portion ,11 with a head or enlarged part 12 at the top and having the lower end 13 arranged to-be mounted .inand supported by a sleeve 14 which is mountedvin a bracketor socket member 15 fastened on the top of a building 16. Drip-means or collar means 17iis" provided between the shank portion 11 and the lower end 13, to prevent any moisture from flowing in ajcontinuous stream down the staff to the bracket and roof, and thereby to prevent impairing the effectiveness of the antenna.

An insulated wire 18' is wound around the shank portion 11 of the staff, and this may be'done by arranging the wire in the form of a balanced winding, with the two ends 18 fastened respectively near the head 12 and near the drip means 17, and the intermediate part of the wire being wound around the staff, as shown in Figs. 1 and 4, thus providing a balanced winding with the middle part 19 of the wire entering a bore 20 provided in said staff, and extending through said bore from substantially the middle of the staff to the end 13, where it is attached to a binding post or connecting element 21 from which a conductor or radio receiving wire 22 leads through the sleeve and bracket toward the radio receiving set (not The wire is preferably a wire covered with a thin coating of insulating substance 18, see Fig. 3, as is well known in this art. The construction used in this form of the invention is particularly arranged as an aerial, for use on the outside of a building,

, and the conductor or wire 22 is the usual lead-in wire.

The form of antenna shown in Figs. 5 and" 6 comprises a staff having a shank portion 24 and a head or enlarged upper portion 25, and a lower end 26 arranged to be mounted in a bracket 27 adapted for using and mounting this form of antenna on a cabinet 01 dresser 28. An insulated wire 29 has its. middle portion 29 fastened to the intermediate part of said shank 24 and is wound around the shank towards the head 25 and j connection with the radio receiving set (not .7

towards the ens-126, the ends 29' of the 'wire then passing through a bore 30 in the stall, out through end 26 and beneath bracket 27 to binding post 31, from which the conduc tors or radio receiving wires 32 extend for shown This wire ma be arran ed as a balanced winding, as shown, or in any de sired manner.

' The form ofantenna shownin Figs 7, 8

and 9'comprises a staff 34having its ends I, supported'in brackets 35 which are mounted 'in-the radio cabinet 36. An insulated wire 37 is wound-around said staff and preferably has its ends 37 extending through a bore 38 in the stalfand extending therefrom to binding posts39 to which conductors or radio receiving wires 40 are connected, which lead 'a bore, and insulated Wire continuously wound-around said staff to chiefly cover the same and partly extending through the walls thereof and'through said bore to one end of the staffan'd being arrangedlfor connection with a radio I'GCGlVlIlg wlr'e;

2. A radio antenna consistlng of a staff of lnsulatln g mater alarranged at one end to be mounted in a socket, a bore provided in said sta-lfaand extending to said end, and an insulated wire wound on saidstafi and partly extendingth rou gh 'zth e wall of said stalf and through said bore to said end and having means for connecting 1mm r'a-dio' r'eeeiving wire; 7

3. A radio antenna comprising a staff 'of" n'isulatlngmaterlal arranged at-amend to bemounted 1n a bracket, a bore being provided in said staff-and extending through said end;
