The object of my invention is to produce a self-contained radio-receiving unit of such character that it'ma'y be moved about from place to place independent of any fixed or.
external antenna and ound, and of such character that, when t. in use, 'ts antenna may, without electric disconnection, be bidden in the casing of the structure so that the device will present the-appearance of a cabinetforming asatisfactory and sightly piece I of furnitur The accompanying drawings illustrate my invention: 1 is, a perspective view of my device with e the reception of radio-signals; Fig.2 is a. fragmentary horizontal section, on a smaller scale, showing the antenna in folded, hidden position; Fig. 3 is a, fra' entary perspective view of a portion 0 theantenna, the full .lines showing an operative or extended position and the dotted lines showing a collapsed condition preparatory to disappearance in the cabinet; Fig. 4 is a wiring diagram and Fig. 5 is a fragmentary detail of a portion of the antenna support.
In the drawings, .10 indicates asuitable cabinet provided with a space 11 for the reception of the folded loop antenna L; a compartment 12 for the reception of the radio-frequency-amplifiersR, R and the detector D; the audio-amplifiers A, A; the potentiometer or stabilizer 13; the rheostat 1 for adjusting the A-battery'current to the amplifier tubes and the rheostat 15 for; adjusting the A-battery current to the detector tube. The am lifiers R, R, detector D and amplifiers A, are so placed within compartment 12 that their light filaments will be visible through the apertures r, 1', d and a, a respectively, and the operating knobs of the rheostats 13, 14 and 15 are projected through the front of compartment 12.
The cabinet 10 is also provided with a compartment 22 and a compartment 23. In the compartment 22, I arrange the usual soparts in position ready for,
usting members 19 and 20, projected through the front cover of com- 41 pivoted at 42 to a spider 43, each holder.
calledA-battery 24 and the usual so-called sufiicient number of cells to provi e'the desired-voltage for. desired maximum range B-battery 25, said B-batterycom rising a of the instrument.' The cover of compartment 22 carrles a switch 26' in the positive line of the A-battery; a switch 27 in one line of the loud talking" born or amplifier 29, which is mounted in' compartment 23, and a multi-point switch 28 which is arranged to control the number ofcells of the'B-battery to be placed in activity. A head piece H (one or more is connected by a suitable length connection with the circuit, in the usual manner, and may be readilystored in compartment-10.v
The -radio-frequency-amplifiers, the detector,-the' audio-amplifierathe vario'-coupler, variable condenser, the head piece, the rheostats and batteries are of well known commercial types, connected with each other by substantial and permanent connections in the ordinary way,.as indicated'by the wir- 1ng dlagram. Fig. 4, the only substantial difference residing in the provision of the multi-point switch 28 which furnishes substantially permanent connections for the various cells of the B-battery, instead of using the usual detachable clip which has been commonly utilized.
Heretofore, radio-receiving sets have, in many instances, comprised units of more or less completeness, but have nevertheless involved the utilization of various detached and detachable members which are unsightly and which furnish a considerable cause of difiiculty in assembly, disassembly, etc., and in fact, produce an apparatus which is unsightly in the average home.
As previously stated, one of the primary objects of my invention is the production of a completed radio-receiving unit which may be moved about from place to place and wholly lacks the necessity of a separate antenna and ground.
To that end, I utilize the loop antenna- L which is supported by a series of radiating insulatin arms 40, each or which is carried at its H1118! end by a tube or holder 41 being held in. extended position by a latch 44 pivoted at 45 andswingable into or out of a notch 46 in the spider, the arrangement being such that by proper manipulation of the latch 44, the holders 41 may be held in extended position as shown in Fig. 1, and
carried by in full lines in Fig. 3, or may be folded down parallel with the shank 47 of spider 4:3, as shown in dotted lines in Fi .3. The shank 47 is pivoted, conveniently at 48 to the up er end of an upr1g t 49 which, near its liiwer end, is hinged at -50 to a stub 51 rotatably mounted ina vertically arranged seat 52 rotatabl mounted in the end of a bracket 53, pivote on a vertical pin 54 carried by base plate 55, mounted on the floor of compartment 11. A sleeve or collar 56 slidably mounted upon upright 49 and the upger end of the stub 51, serves, when desire to hold the upright ,49 in ver-' tical position.
-Seat 52 is held in bracket 53 by means of a collar 57 through which is threaded a set screw 57 which also projects through the wall of seat 52 and engages the lower end of stub 51, the arrangement being such that the single'set screw 57' holds the parts in .asembled position and also serves as a limitin conjunction with the stop 58, bracket 53, to limitrotation of upright 49 to slightly less than one complete ing finger rotation, so that the line wires 62 which connect the loop antenna in the system, may not be twisted ofi.
The construction of the loop antenna and its support is such that it may be supported as shown in Fig. 1, in such manner that it 'may be turned about a vertical axis in order to be properly pointed toward the desired sending station or it may be collapsed and readily folded away in the compartment 11.
The interior of the casing 10, comprising compartments 11, 12, 16, 22 and 23, may be conveniently closed, so that the apparatus ma be hidden, by suitable doors 65.
he line wires 61, 62 of the loop antenna y a rule 'oint,
connect with the system in the usual manner but, as alread pointed out, this connection is a practica y permanent one which does not need to be ever disturbed in the use of the apparatus.
' It will be seen from the above that I have provided, as a single and complete unit, a radio-receiving apparatus which may be readily expanded for use and collapsed for storage without disturbing a single electrical connection and such that it may be readily shifted from place to place in aresidencewithout in any way alfecting its effectiveness.
I claim as my invention:
1. In aradio-receiving apparatus, a loop antenna comprising a base, a bracket pivoted upon the base, a standard pivoted in the bracket and comprising three hingedly connected portions, radiatin arms pivotall connected to said standar means for hold ing the arms in radiated position, and aloop of wire carried by said radiating arms, substantially as and for the purpose set forth.
2. A radlo-receiving unit, comprising in combination with a portable cabinet having a radio-signal receivmg unit, complete in itself, mounted therein, of a collapsible antenna permanently connected into the receiving unit and independent of all external connection, a standard on said cabinet and said antenna, said antenna and standard bein collapsible into or projectible from the ca inet without disturbing its circuit connections.
In witness whereof, I, JOHN S. FISHBACK, have hereunto set my hand at Indianapolis, Indiana, this 25th day of March, A. D., one thousand nine hundred and twenty-two.
