Application lied January 81, 1922. Serial No. 583,093.
K. To all 'whom it may comm:
Be it known that I, Dawn-s H. SHAnL- cnoss, a. citizen of the United States',.res1d ing at Clarendon, in the countyof Arlington 6 and State of Virginia, have invented certain new and useful Improvements'ln Suports for Radioantenn, of which-the fol owing is a specification. v
M invention relates generally to supports for oop types of antennas and more particularly to those used in connection with apparatus commonlyknown as the radio compass, radio direction finder, radiogonometer or directional loop, and more specifically to the frame upon which the loop or coil iswound'and has for an object the provision of a structure which is both rotatable in and ,demountable from its SUPPOrf Another object of the inventlon 1s the pro# vision of a structure which may be col- `lapsed permitting easytrmsportation and storage thereof. v
With these and other objects in vlew the invention consists in the congtructiou, combination/and lmp. l 1; Il :l V0l be hereinafter described.
Reference is to be had to the vaccompanying dra fo partof this specification, in which likere ce tclllilaracerstmtcate corresponding A arts ug ou e several views, in w 13x;

Fig. 3 is a sectlonal view showlng the manner of connecting the structure with its su rt i s 1g. d is an enlarged view partly in section showing the manner of supporting the framework of the Structurae, I

Fig., 6 is 'a modification of the supporting means for theframe,
Fig. 7 is a modification of the wircholdin means,
' i 8 is a view on the line 3 3 of Fig.
'7 Fig. 9 is a ldetailed view of the manner of threading the coil on one of the members of the frame. Y
Referring more particularly to the drawparts as will which is ings, the'numeral 10 indicates a hollow shaft 55 on which is detachably mounted the central casting l1 and on which is provided an insulating terminal rin 12, preferably constructed of bakelite.` lectrlcal conducting wires 13 pass through the lower portion of 60 the shaft and are connected at their upper ends to terminals on ring 12, the. lower ends of the Wires being provided with plugs so that they may be easily and quickly connected to or disconnected from the main electrical conductors 14 as will be morev fully explained hereinafter. y The central casting 11, shown in detail 1n Figs. 4 and' 5, comprises a body section 15 from which extend the wings 16, the side edges of which converge from the bodyportion of the casting forming an enlarged platform on which are secured a plurality of sockets 17. The win` 4have portions of A their side ed es upturned as at 18, forming a stop where yV the sup rting arms of the frame structure are heldoin ope-rative'position. Reinforcingwebs 19 are integrally formed between the win 'While I have shown a tapered pin 2O ely connected to 80 one of the arms for fastening the casting to f the shaft, any suitable means for this purpose may be employed. g
The frame on which the wire 21 forming the coil is Wound com risessupporting bars 22 which are provide with balls 23 engag` ing in the sockets 17, permitting .a free movement therewith. To prevent the ball from Yaccidently becomingdisengaged from 4 its socl'ret, I provide a resilient member 24 sitioned on the wing 16 in proie. imity to t e socket 17. The supporting bars are hingedly connected at their outer extremities tothe cross bars 25, which bars have their ends grooved as at 26 to receive tongues 27 formed on the supporting bars 22, as shown in Fig. .2, whereby the connection between the two bars is made more stable. The cross bars 25, which I preferably construct of wood, are hinged at their central portions and have a sliding connection through a pin 27 engaging in a slot 28 in central bars 29. To secure and prevent accidental displacement of the bars 22 while in extended position I provide a tie connection between the upper and lower sets consisting of a rope, w re or chain 30 secured to the supporting ars adapted to Fig. 2, and then secure them in this position b wrapping the tie connections theiea ut. `e sliding movement along the central bars 29 allows free movement of the cross bars without straining the coil v wire 21 during the movement ofthe outer i Asha sures proper connection extremities of the cross bar.
The wire 21 is wound upon the frame by passing it through slots 32A formed in a strip of insulating material 33, there being a strip secured in any desired manner to each section of the-cross bars 25. The free ends of the wire are: connected to terminals on ring 12, thereb forming electrical connection with the ectrical conductors 13. In order that each turn of wire in the coil may be in a true vertical position on the frame I re rably form on one of strips of a channel the bars 25 i construction, as maybe clearly seen in Fig.
9. In each of the sides 34 the slots 32 through which the wires pass are in alignment, and in alignment with a ll corresponding slots in other bars 25,v` the wirirf being brought through aslot in one si e 34,
then crossed over to the adjacent slot inV side andethen taken around the the opposite frame structure to the slot. in the first side which is intlignment with the slot through whichthe wire left the strip, and so on.
In Fig. 3 I have shown the general and preferred manner of connecting the structure with its support. In this view 35 is the deck of a veel or floor or roof of a building having an opening therein which o ning is closed by a plate 36. A housing 3 containing the operating machinery (not shown) is secured to the underside of the deck or door or roof andinto which is threaded the plate 36. A sleeve or bea 38, suitably supported at its lower en passes through an o ing in the plate 36 and receives the sha -10, which is secured therein against movement by a pin, preferably of tapered construction, passing through the opening 39 in the shaft 1 and en ng in an opening in the sleeve 38. 41 secured to the sleeve 38 carries the main conductors 14 which terminate in the electric socket 42 for the reception of the plugs secured to the conductors 13. Key 40 engaging in a key wa in sleeve 38 asween plugs 13 and socket 42. Sleeve 38 is rotated through suitable operating machinery (not shown) -spaced intervals slots 43 having their pre end only the and thus rotates the structure mounted on shaftjlO. It will be seen that easy lconnection or disconnection may be had and the structure readily demounted., By the modification of the holding means shown in Fig. 6 I Eermit; easy removal of the balls 23 from t eir sockets 17 by constructing. the sockets with one side open. After the supporting bars 22 so that it will avoi the upturned edges 18, lateral movement ma be imparted to the balls freei them om their sockets. y
e I have shown the coil wire 21 passing through openings in the strip 33, I preferto construct this wire holding means as shownin Figs. 7 and 8, wherein I use an insulating strip -42 ha at regularly curved as shown. The wire is held in ge grooves by a strip 44 of any suitable insulatmaterial which is fastened to the intng strip 42* inV any desired manner after the wire is inserted.
It is to bedunderstood that dtrle above descri tion an accompan wings comguidi-:lf and preferred embodiment of my invention in that minorchangesv in the details of construction, proportion and arrangement of tplai'ts may be made within the scope of e,I appended claims and without sacrificing any of the advantagesof my invention.
