- To all whom it may concern: I

'Be it known that I, ALEXANDER E. BROWN,

a citizen of theYUnit'ed States, residing at 'Cie'veland, in-the county of Cuyahoga and State of Ohio, have invented a new and useful Support for Crown or Antenna Wires for Electric Masts; and I hereby declare the following to be a full, clear, and'exact desoli tion of the same, reference being had to 't e drawings accompanylrg and making-a: part of this application, wherein similar arts in each case are denoted by thesame re erentlal letters.

As indicated above, invention relates,

generally, to the apparatus employed in space, or wireless telegraphing wherem electrically produced vibrations'are to be radiated, or received at an elevated point, above casesan insulated cylindrical metallic column or shaft, that carries, at its top, the

necessary crown, or antennae wires, that are spread around the top and usually supported, in such position, by a definite frame-work of its construction,

rigidly fastened to the mast itself. Heretofore there has been no manner of thus aflixin the frame-work to the mast, that has ermitted the withdrawal of the same, an its attendant wires, from their normal place, without a total dismantling of all the arts involved. This operation, besides fieing costly and slow, must, necessarily, be undertaken under conditions that make the result uncertain and largely dependent, for any expedition, at least, on the articular circum stances or situation in eac case;

It is the object of the invention I am now about to describe, to aflord a form of support for the antennae w1res of an electric mast, that is adequate for thatpurpose and, at the same time, by reason of the mechanical principle dis'membering the same, can. readily be manipulated whenever it 1s desired to inspect, renew or repair such wires, or frame. To-thls end,- as,- set forth in the several figures, I

show, as a primary element of the arrange- As will be under and without the need of ment, when comprehensively considered, an electricall insulated mast carrying and surmounted y a support for its antennae-wires that can always be mechanically withdrawn, or extended, from the mast to the normal, as occasion requires, and without any special preliminary steps.

'In he drawings accompanying,and intended to make clear my said invention, Figure 1 an enlarged view of the top of a mast, equipped wit my invention, when the antennae wires, su ported by the same, and the. support'itsel are withdrawn to the mast for inspection, repair etc. enlarged-view of the top of a mast carrying said support, Fig. 3 is a downward plan of the frame of said support with antenna wires st across the same, Fig. 4 is a plan view of a etail of a mode of connecting thesustaining wires to the. outer extremities of the gafis or booms employed as a part of said support, Fig. 6is an elevation of a portion of the mast,

s'liding engagement with the same, Fig. 7, is a plan view of the arts shown in Fi 6. Fig. 8 is an-enlarge sectional view 0 the shoe and guide detail shown in Fig. 7. Fig. 9 shows a mechanical arrangement fixed at out, the sustaining wires when said su port is withdrawn for inspection or is extended to its normal place. Fig. 10 is a down plan of Fig. 9. Fig. 11 is an elevation of a special form of the support where both horizontal and vertical antennae are used, the front booms be' removed. Fig. 12 is an elevation of anot -erspecial form where the lower frame structure of the support-is permanently fixed to the mast. v

In the drawings M s the mast proper (which, as said, is a hollow cylindrical shaft provided with an interior ladder m) and G G and G its sustaining guys. b b '6 b and 6 indicate repair. balconies on said mast.

sents an insulating hood over the guy terminals. Sui-rounding said mast, near its top, is a square frame-work whose sides are, each, made up of channels fand f, fastened together, at their inner ends, by means of gusset plates 1), p. Said frame-work is connected with a second and interior frame- Fig. 2 is an' Fig. 5 is'a side elevation of Fig. 4..

and'of that part of said support that is in the top of the mast for taking in or letting O is a canopy at the mast top, and'l repreare made to converge,

Work, around the mast, bytlie struts s s that extend, respectively, from the corners,

' plamed. Said outer frame-work i's, further connected to a second inner frame-work F, below, (like and similarly related to the mast as the first) by the several struts 8 thereby, forming, with the latter, a firm frame-structure with two horizontal bearings against the mast. At diametric points on the sides of said outer frame-work, between the clevis-bearings sEecifie'd, are vertically pivoted booms or go. s B to which the an; tenn'zc wires are to be strung. They are of such length. that,when distended diagonally u ward, the field or area between their ends, sli allbe ample for the purpose. They are stayed against lateral movement by guys, g", on each side of the same,'th-at are anchored to the corners of said structure, and the latter should be of suitable dimensions, in every case, to afford the requisite purchase for the pur ose. Backstays if from the outer ends'of t e booms to a suitable distance on the mast below are also shown and on each side of said outer ends is a horizontal sheave and block V transversely pivoted thereto by ivotso. Sustaining ropes R are stretched etween and from the ends of adjoining booms, when in their distended or normal positions, to which ropes antennae wires N are attached and their'free ends brought together in a knot (Fig.'3) and connected directly to the mast, when metallic, or to suitable conducting Wires when the mast is a non-conductor. be seen, that, under these conditions, when the booms-B, and sustaining ropes R, are- -1n their normal posltlons the antennae, ar-

ranged as just described, will lead or extend to the mast in a horizontal plane.

Between the inner edges of the plates and the mast M, are upright shoes S, consisting of an upright angle-bar or piece fastened to said plates with their legs toward the mast between theoutwardly extending flanges of a vertical '-ch'annel-beam'C, that is riveted to'the exterior surface ofthe mast for the. purpose. The channel beams C should-extend downwardly from the highest travel or point on the mast to beoecupied by the boom-frame above described, to a distance from the top of them'astequal- "to the length of a boom and the distance between said outer andinnerfraine-works.

the booms B Y -ter of the mast.

' the It will of course sense At afixed point on the mastM immediately above said highest poidt on the same, is located a chain-hoist system, made up of two chain-hoist wheels H, H, at opposite sides of the mast, upon an axle'a, (passing through the mast), and the hoist-chains 0. One end of the hoist-chains c is fastened to said frame structure and, as indicated in Figs. 6 and 7, suitable means for operating said system, by a worm- 'earin for instance, actuated by the whee h an chain 0' located within said mast. j 4

At the top of the mast is an arran emeut for taking in the sustaining ropes and their antennae-wires, consistm of four diametrically related sets of two ruins each D, D, at the exterior of the mast near the top. These several sets are arranged in pairs, revoluble upon common shafts X, and are provided With ratchete r, at the end and intogral with each drum. Pawls P and P, are provided to be brought into gear with said ratchets to control the drums so they may be operated either simultaneousl or separately, the former pawl being ed on the. frame-work of the drum and, the latter, piv-' oted to a socket T-, that engages the shaft X, of a hand-lever L, extendin toward the cen- Below t e drums D is a framework to, inclosing and rigidly fastened to the mast that carries diametrically arran ed sheaves '0. Balance ropes Z, are, re erably, attached to said booms, and mu ht around said sheaves downwardly to amework to which the booms are affixed. The sustaining-ropes R, are reaved around the sheaves V, at the end of and between each adjoining pair of boomsB, and, thence, are brought to and around, from the under side of the drums D, in each case, and fastened to'the same.

In the special application of my invention more particularly set forth in Fig. 2, it is manifest that, by the arrangement of the guys and ropes shown, the booms will be securely stayed and held in their normal or extended position, but that, by reason of the peculiar method of connecting them to the mast, they can readily be withdrawnto the mast, with the attached antennae wires,.whenever it is desired to inspect, or repair either the wires, or any part of the supporting frame. Allthat will be necessary, in such case, will be that an operative take a osition within the mast, and by means 0 the wheel h and chain c, unwind, or reversely turn-the chain-hoist wheels H, and, thereby allow the frame-structure, to which the booms B, are pivoted, to descend by gravity down the channel-beam guides C, until the booms are drawn in and lie vertically near the mzistto their full length, as shown in Fig.- 4. During this process, a second. operative wiljl,-in turn, have actuated the drums D carrying the sustaining ropes R, by means of take up'the slack'of'the free portions of said i antennae wires, it is plain that it will merely be 3 the hand-lever L, in engagement, through the pawls P, with the ratchets r, so as to ropes, as the booms a pmtghthe mast; In

..said operation both members of each pair of drums are worked'in unison, but. when it is only desired, for instance,. to' tighten up a particular sustaining rope, with its. attached necessary, to throw out of ear thepawl P,

' of the companion drum on. t elsame shaft X,

' will only be necessary to reverse the direcand the other drum member, controlling the rope to be tightened, can then be workedalone and independently of the other. It is evident, also, that, by allowing the. framestruct'ure to-which the booms are attached, to descend to the full length of the channelguides C, as described, thea'ntennae wires can be taken in during the process, .hand over hand, and examined, and repaired or replaced' In order to cause-the booms {and their wires to resume their norn1al-places,'it

tions just given for withdrawing them from such places. I v

Special forms for multiplying the wirecarrying capacity of a sup 'ort, of the'character I have described, are i lustrated in Figs.

1-1 and 12. That shown in Fig. 7 1 1 diifers from the previously shown form by the introduction, below the set of booms shown before,

' of a duplicate or secondary set of booms piv oted toa second-frame structure like the first, and, oscillating. in upright guides, on the mast, C C for the purpose. Said latter set of booms, carry between their outer extreniities, a sustaining rope B, to which are attached the lower ends of antennae-wires N,

. which extend vertically from the upper 'sustaining ro R. The-sustaining ropes R are attached irectlyto the booms B without the intervention of, sheaves corres ending with V, and any drum arrangement or with-. drawing the same to the mast, as in case of the upper set, is unnecessary, inasmuch as the lower frame,-to which the booms B are pivoted, is connected or tied directly to the upper oscillating frame to which the booms B are, pivoted, by hangers E, so that whenever the upper frame is oscillated, the lower frame will t ereby be carriedup or let down,

as the case may be. b is a repair balcony for the lower booms and wires, located at the i point on the mast where the ends of the ered 'to its full predeterrmned limit.

7 Still another special form of support is shown in Fig. 12. In this form there is an nlpper arrangement of booms etc. like that own in previous figures, and a lower framestru'cture to which booms B are pivoted, as

in the form shown in Fig. 11. This lower frame-structure, however, is not arranged to oscillate upon the mast, but is permanently fixed at one point thereon, with back-stays t tfrom the endsjof its upper booms B, an

chored to the mast, rather than to the lower booms B; fl)" is a balcony on the mast, at the point where the ends of the booms B against or vertical ba cony are located cated 1 by U for windi in the ropes l l whichextend from the. ends of the booms B- and are fastened to said winding mechanism,

and thereby serve bothto sustain its booms and their allied parts, it will only be necessary to lower the frame-structure to which their booms are ivoted, by unfastening the backstays t an then winding in the rope Z until too the booms are broughtupright on their 'ivots close tothe mast. It ,is clear that 'ke the arrangement shown in Fig. 14, the last described arrangement makes it entirely ractica'ble "to handle either set of booms independently of the other, or both at the same" time. p

I wish it to be unders tood, that I do not.

-wish m invention, in thbroader sense, to

be co ed to only those forms of construetion where the several features described are present in the precise form displayed; in such p sense the several methods of staying or guying the different parts, for instance, are not of the essence of the invention, nor the pe- I culiar arrangement of the sheaves, drums,

or frame-structures, or the exact number of the frame-structures shown and appendant booms, the main or controlling idea, being the boom supports, vertically pivoted to an oscillating frame-structure or structures to and between which booms the antennae are flexibly strung.

, WhatI claim'and desire to secure byL'etters Patent is;
