ATTORNEY TELEVISION ANTENNA Filed July 15, 1948 2 Sheets-Sheet 2 JACOB .W!NER ATTORNEY Patented Feb. 7, 1950 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to new and useful improvements in television and FM antennae.

The invention particularly proposes a television and FM antenna which may be mounted outside of a window upon the window frame, or upon any other frame having two side arms. It is proposed to so construct the new antenna that it may readily be mounted in position without the use of tools, except for a turning key for firmly locking a clamp nut in position.

The invention makes use of a new antenna assembly made from a number ofsections, certain of which are telescopic in order that the antenna assembly may be extended and retracted, and other sections of which are releasably connected with each other so that the antenna assembly may act in different ways, namely, it may constitute a folded di-pole, or dipole and refiector, .or a di pole anddefiector.

The invention further contemplates simple mechanism for supporting the antenna assembly in universal positions. With this arrangement the antenna may be suitably directed and ad'- justed to .a most optimum position for any television or FM station, so as to intercept the signal H from any point of the compass.

Another object of the invention is the construction of a television and FM antenna as described, which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure- Fig. l is a plan view of a television and FM antenna constructed in accordance with this invention.

Fig. 2 is a front elevational view of the antenna shown in Fig. 1.

Fig. 3 is a vertical sectional view taken on the line 3'-3 of Fig. 2.

Fig. 4 is a fragmentary enlarged detailed view of a portion of the antenna assembly, certain parts being broken away to disclose interior parts.

Fig. 5 is an enlarged detailed sectional view of a portion of Fig. 4 illustrated with two of the each other to convert the assembly to a di-pole and a reflector or deflector.

The television and FM antenna, in accordance with this invention, includes a horizontal support in for extending across a window frame schematically shown on the drawings and indicated by reference numerals II. The horizontal support I 0 isassociated with clamp means for mounting said support Ill in position across the frame II. This clamp means includes a threaded rod l2 threadedly associated with the support If]. Clamp channels 13 are mounted on the outer ends of the threaded rod I2 and the support ID.

The support ID is in the nature of a tube. A stud i4 is mounted in and projects from one end of the support In and passes through the back of one of the channels I3. Suitable washers I5 and 1-6 engage on the stud M. The outer end of the stud I4 is threaded and provided with a nut IT. The other end of the support I0 is equipped with a pair of spaced nuts 18 and H) which are held from shifting by being clamped by the material of the support If) and furthermore by abutting against studs 2c mounted through the support Ill and engaging the inner sides of the nuts 18 and [9. The threaded rod I2 threadedl-y engages through the nuts I 8 and IS. The outer end of the threaded rod I2 passes centrally through the back of the other channel IS. A group of washers 2! is mounted upon the outer end .of the threaded rod I2 on opposite faces of the back of the channel l3. A nut 22 is engaged on the rod 12 and is held in a fixed position with a cross pin 23 engaged through the nut 22 and the rod [2.

A lock washer 24 is engaged in between the nut 22 and the adjacent washer 2|. The horizontal support l0 maybe firmly clamped in the frame H merely by turning the rod 82 to extend the rod 12 so as to expand the channels l3 to engage the rails in a window frame or other parts thereof. When the channels I 3 firmly rip the rails, a turning tool, such as a length of pipe or a special turning tool is engaged upon the pin 23, and the rod 12 is strongly turned for tightly clamping the horizontal support In in position.

A clamp connector 25 is turnably mounted on the support 10 in order to assume various turned positions on said support in. This clamp connector 25 is in the nature of a block having an opening 26 through which the support 10 passes. The opening 26 connects with a slot 21 extending to the end of the connector 25. A clamp screw and nut 28 engage through this end of the connector 25 by which the connector 25 may be clamped on the support [0 or released.

The other end of the clamp connector 25 is provided with a vertical opening 29 communicating with a vertical slot 30, see Fig. 1. A clamp screw andnut 3| engages through the latter end 3 of the connector 25 by which a post may be clamped in the opening 29. A post 32 is mounted on and projects from the connector 25 by having its bottom end engage in the opening 29. This post 32 extends in a plane at right angles to the axis of said support H]. A clamp knuckle 33 controlled by a clamp screw 3 1 is disposed on the top of the post 32 and is bendable in a plane sub-,- sltantially common with the axis of said support An insulation member 36 is turnably mounted on said clamp knuckle 33. More particularly, the clamp knuckle 33 is provided with a vertical stud 37 passing through an, opening formed centrally in the insulation member 30. A clamp nut 38 is mounted on the top of the stud 37 by which the insulation member may be clamped in various turned positions upon the clamp knuckle 33. An antenna assembly 49 is mounted on said insulation member 36. Said antenna assembly comprises a pair of tubes 4i and E2 aligned with each other and projecting from opposite sides of one end of the insulation member 36 and connecting with terminal posts iii? mounted on the insulation member 36.

Tubes 43 telescopically engage in the outer ends of the tubes 4i and 42. A small spring 44 is engaged in each of the tubes ii and 42 and engages against the sides of the tubes 43 for friction-ally holding the tubes 43 in adjusted positions. The insulation member 36 supports another tube 44 extended through its other end and arranged parallel to the tubes ll and 42. Telescopic tubes 45 engage in the ends of the tube 44. Small springs 94' are mounted Within the ends of the tube 4% and engage the inner ends of the tubes 45 for frictionally holding the tubes 45 in extended or retracted positions. The outer ends of the

tubes

43 and 45 are connected by U-shaped connectors 48. These U-shaped connectors 46 are provided with thread studs 41 at their ends which threadedly engage in the outer of the

tubes

43 and 45. The connectors 56 are in the nature of bent tubes, see particularly Fig. 5.

The antenna assembly 60 may act as a folded di-pole when the U-shaped connectors 46 are connected with the

tubes

43 and 45, as illustrated in Fig. 1. In this position the

tubes

43 and 45 may be extended or retracted to control the spread of the antenna assembly. If desired either the tubes 43 or the tubes 65 may be turned so as to unscrew from the studs 4'! of the connectors it to cause the antenna assembly to act as a di-pole with a reflector or deflector. In Fig. 9 the antenna assembly is shown in this condition.

The operation and use of the new television and FM antenna may be understood from the fol- 4 dot and dash lines in Fig. 1. Furthermore, the antenna assembly 40 may be pivoted by pivoting the clamp knuckle 33 as indicated by the dot and dash lines in Fig. 2.

The main feature of the new television and FM antenna resides in the fact that it may easily .be mounted across a window frame or other frame, and then the antenna assembly adjusted to a position best suited for reception from any particular television or FM station. Moreover, the antenna assembly may be adjusted to act as a folded di-pole or as a single di-pole and reflector or deflector for eliminating ghosts on the television picture.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifica tions coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

A television and FM antenna, comprising a horizontal support for extending across a window or other frame, clamp means for mounting said support in position across said frame, a clamp connector axially turnably mounted on said support in order to assume various turned positions on said support, a post mounted on and projecting from said connector in a plane at right angles to the axis of said support, a clamp knuckle on the top of said post bendable in a plane substantially common with the axis of said support, an insulation member turnably mounted on said clamp knuckle, means for clamping said insulation member in various turned positions on said clamp knuckle, a di-pole mounted on and projecting from said insulation member and having telescopic extendable and retractable end sections by which said di-pole may be extended and retracted, a reflector or deflector directional tube mounted on and projecting from said insulation member parallel to said di-pole and having telescopic extendable and retractable end sections, and U-shaped end sections releasably connected with the outer ends of the telescopic sections of said di-pole and directional tube in order to form a folded di-pole, and said U-shaped end sections being releasable for disconnecting said telescopic sections in order that said di-pole and directional tube act independently.
