RADIO RECEIVING DEVICE `Application. filed `July 21,
` My invention relates vto portable radio rei `ceiving apparatus and has for its principal object the provision of an antenna for the receiving apparatus which may be easily set up in operative position on the container for p the apparatus or packed away with the applace to place.V
i adapted for use either as a loop antenna or in conjunction with the set and a large outside antenna as a transformer `having the primary connected in the outside antenna circuit and a secondary connected tothe receiving apparatus. y,
Other objects and advantages of the invention will appear as the description proceeds when taken in connection with the ac` companying drawings wherein the preferred form ofthe invention is disclosed. However, I wish it to be distinctly understood Vthat I do not intend `to limit myself to the exact details shown and described, `but that I intend to avail myself of all such modications as would occur to one skilled in this art and as fall within thescope of the claims.
In the drawings: Fig. 1 is a front view showing my improved antenna set up in operative position with respect to the portable receiving apparatus in conjunction with an outside antenna;
Fig. 2 is a section onthe line 2-2 of Fig. l; and
Fi 3 is a plan view showing the combine loop antenna and transformer mounted in the cover on the portable container hous-ing the receiving apparatus.
Referring now indetail to the drawings, the numeral 5 represents a container having therein a portable radio receiving apparatus such as that shown in my co-pending application Serial No. 151,773, filed November 30, 1926, for portable radio receiving sets. This container as shown is provided `with a handle 6 on top thereof and in the front face the opening 7 through which the sound waves emanate from the set, and in i927. seria; No. 207,456.
the lower portion of the front face is providedwith a tuning dial shown at 8 an the connecting posts 10 and l1. i
This front face is provided also with a false cover 112 shown in Fig. 1 inopenposition, which cover as shown in Fig. 3 is adapted toreceive and` detachably retain the frame member` `13 therein. This frame member, `which may be constructed of any` suitable material, is provided at one end portion thereof with the hinge member 14 having the depending pin 15 thereon fitting in an opening 16 provided in a mounting mem-` ber 17 on top of the container 5. The hinge member 14, as shown clearly in Fig. 2, `is adapted, when it is desired to store the frame within the cover 12, to swing upwardly within the confines of the frame member and in this position forms` a handle whereby the frame member may be lifted ont of the cover.
The frame member 13, as shown, is provided with an external groove extendingI around tlieouter surface thereof and in this groove there` are wound the primary coil 20 consisting of a small number of turns of: insulated wire held out of engagement `with the bottom of the groove by means of the insulating spacing members 21 provided at each `angle in the `frame member. This primary coil has one end secured to the binding post 22 and the other end thereof secnredto the binding post 23 whichbinding posts may be connected by suitable leads shown at 24 and 25 to an aerial 26 and ground 27. Also wound in the groove in the member 13 are relatively large number of turns of a secondary coil 28 which is spaced from the primary coil 20 by means of the spacing members 29 mounted at the corners of the frame 13. This secondary, as shown in Fig. l, has
y a pair of leads 30 and 3l connected to the op- 2f f, Y Y Larose Now Whenit is desired to use only the loop antenna, no connections are made at the binding posts 22 and 23, and the secondary coil 28 is utilized as a loop antenna for the 5 interception of radio Waves and their transmissionto the receiving apparatusl housed Within 'thecontainer 5. The frame 13, there- Y fore, with its primary and secondary Vcoils `2O and 28 is very readily adaptable for use `either 'as "an antenna 'or as a transformer in v 1 l v Y connection with a separate antenna when desired. Y l
This vconstruction also has the advantage that it can be readily dislnounted and fitted v 5 Within the cover l2 for transportation cpurpose, the cover 12 serving to protectthe ad-` justing dials lonfthe face of |the container 5 Y and at the same time to lcarry the antenna i structure.y A Y Y x v' ,It is thought that the above description f will make the construction and advantages` of this invention apparent k*to 'those skilled in. `this art, and having thus described my inve'n tion what I claim and 'desireto secure by Letters Patent'or- 'the United States is:
, l.V A combined transformer 'and loopV antenna comprisingv a rigid supportingv frame, a primary 'coil Wound thereon and having terminals vfor connection to an antennay and ground, a secondary coil' 'forming-'a loop '-:an- VtennaWound on said ramevand 'having connesting leads for connection to la receiving apparatus, and a support member hinged to` Y said frame and movable from a position Within 'the outline of said frame to support- 1 ing position exteriorly of said frame. Y A2. A loop"antenna" comprising la rigid I Viframe forminga closed loop, said frame having means in the outer surface thereofl sup- 40' porting a Wire coil and a support memberv for mounting said rame'securedthereon and movable from a position'vvi-thin-'the outline and plane of said rametfo an opposi'te'position exteriorly' of said'fra-r'n'e forsupporting 45, said frame. i ,5
