RADIO LEAD OR AERIAL Filed Aug. 19, 1929 WI Mala/ C. SAMPfi'OAI,

PATENT OFFICE J'OI BIN C. SAMPSON, OF STILOUIS, MISSOURI name LEAD onnrmm Application filed au ust 19, 1929. Serial No. 386,775.

'.l his invention relates to radio leads or aerials, and more particularly of the type having the form of a'tape and designed for attachment to a building structure. Such a 5: tape .usually consists of interwoven wire and fabric strands, and is-used for the purpose of receiving the Hertzian or radio waves and also to act as a lead from the aerial to the receiving set. Difllculties, however, are encountered in mounting such a tape so as to secure insulatlon and mamtenance of the same in constant operative position for the reception of radio waves; for this can not be efi'ectively' secured by the usual method of application, by the employment of tacks or other metallic fasteners.

One of the objects of this invention, therefore, is to-provide a radio lead or aerial, which is so constructed that it can be readily mounted and applied; and, when so mount- .ed, will be maintained in constant operative position forthe reception of radio waves while at the same time securing insulation.

' Further objects will appear from the detail description,taken in connectionwith the accompanying drawings, in which Figure 1 is a perspective view, partly in section, of a portion of a radio lead embodying this invention; 7

Figure 2 is a similar view, showing another embodiment ofthis invention; and ,Figure 3 shows a roll of the radio tape.

Generally stated, in accordance with this invention, the radio lead or aerial comprises a flexible electro-conductive tape provided with an adhering facing of suitable cement, so that-the lead can be adhesively attached by that facing to the wall or any other support to which it is desired to-secure it, whereb it may be supported in operative position. This facing-is, however, preferably a nonconductor, so that whenthe lead is applied to an ordinary wall of considerable cgnductivity,.leakage will not occur. A suitable cement adapted for. this purpose is one having a rubber base and which is, and remains, tacky. There are a number of non-drying or slowly; drying "rubber cements, such as those used in the making of insulating tapes,

- which accomplish this purpose; where, however, the facing is on a wholly metallic lead, then, of course, a cement must be employed which,-in addition to bein tacky, also will firmly adhere to the meta ic lead. Where the lead is in the form of a'flexible tape, it is rolled up with the convolutions adhering, so as to provide a convenient package. Wherethe lead is used for outside employment or in places where it subject to humid conditions, the lead itseltis protected by enamel. v v 1.

Referring now to the accompanying draw ings, and more particularly to Figure 1, 1 designates aleadand 2 the facing. The lead is preferably in the form of a flexible .tape and may be constructed of thin metal, such as copper. Another suitable embodiment is, however, one made up of metal (such as copper) and fiber ('such'\ as cotton) strands, I

which are interwoven in a manner well known to those skilled in the art. 1 The adhering facing is applied to this tape, and this, as above stated, is one which remains, permanently tion, be a non-conductor, and a tacky. rubber cement'will fulfill both of these functions.

In the embodiment shown in Figure 2, the lead or tape has applied thereto a coating 3- of enamel, this coating being applied to what forms the outside face as well as the edges, while the cement is applied to the inner face. The tape is, therefore, protected against weather and other conditions to which it may be subjected in use.

' As shown in Figure 3, the lead can be rolled up to form a package, or roll, in which the several ponvolutions are held together by the tacky, adhesive employed. The tape 'can, however, be drawn from this roll as desired for application. I

The method of application will be'apparent from the above description. It is simply necessary to press the tacky facing of the lead against'the surface to which it is to be applied and to which it will then firmly adhere. Forthi's purpose it can be run in a loop about the room to form an inside aerial, with an end thereof leading from the loop and to the receiving set, against the cabinet,

to which it can also be applied to secure a vention have been described, it will be understood that this invention is susceptible of various embodiments and of various uses, particularly in the radio art. It will furthermore be understood that certain features and sub-combinations are of utility and may be employed without reference to other features and sub-combinations; that is contemplated by and is within the scope of the appended .claims. It is furthermore to be understood that various changes may be made in details of construction, without departing from the spirit of this invention. be understood that this invention is not to be limited to the specific details shown and/or described. I

Having thus described the invention, what is claimed is:

1. A radio arial designed for attachment to a building structure andcomprising a flexible electro-conductive tape provided with an adhering facing whereby it may be adhesively attached to the building structure and maintained in constant operative position thereon for the reception of radio waves.

2. A radio aerial designed for attachment to a building structure and comprising a flexible electro-conductive tape provided with an insulating adhering facing whereby it may be adhesively attached to and insulated from the building structure and maintained It is, therefore, to

vided with a reinforcing flexible fabric backing and an adhering facing carried by said backing whereby the foil and backin may be adhesively attached as a unit to the uilding structure and maintained in constant operative position thereon for the reception of radio waves.

6. A radio aerial designedfor attachment to a building structure and comprising a flexible reinforcing, fabric tape having an electro-conductive material supported on one side and provided with an insulating adhering facing on its other side whereby it may be adhesively attached -to and insulated from the building structure and maintained in constant operative position thereon for the reception of radio Waves.

In testimony whereof I affix my signature this 7th day of August, 1929.

in constant operative position thereon for the reception of radio waves.

3. A radio aerial designed for attachmen to a building structure and comprising a flexible electro-conductive tape coated on one side with a protective coating and provided on its other side with an adhering facing whereby it may be adhesively attached to ,the'

building structure and maintained in constant operative position thereon for the re I ception of radio waves.
