Fig.16 isacross- Vhat I have termed the bracket 8 is section online 16 1G, Fig. 15. Fig. 17 isa depreferably clamped to the mainmast 1. It is preferably composed of two clamping portions 17 and 18, which surround the mast and a supporting-arm 19, attached to or formed integral with the part 17 and projecting out therefrom. The inner sides of the parts 17 and 18 are preferabl y so formed as to make close contact with the sides of the mainmast, and where the mainmast is formed of clusters of pipes, as shown in the drawings, the inner sides of said parts should preferably contain vertical grooves 19, adapted to fit around and receive the outer sides of the outer pipes,substantially as shown in Fig. 7. This prevents the bracket from turning where the mainmast is formed as shown and enables it to be clamped in place more securely than would otherwise be possible. The clamping part 17 has on each inner edge an outwardly-projecting flange 20, and the clamping part 18 is provided with similar flanges 21 21 on its inner edges, and these flanges 2O and 21 face each other when the bracket is in place, as shown most clearly in Figs. 6, 7, and 9. Said flanges 2O and 2l are pierced by bolt-holes 22 and the bracket 8 is clamped in position by means of bolts 23, passed through these holes, and the nuts 24, screwed onto said bolts. Vhere the mainmast is formed as shown, a core-piece 6 is preferably arranged within the circle of pipes 3 about midway between the ends of the clamping portions 17 and-18, so as to brace the pipes 3 against the inward pressure eX- erted by the bracket, and in placing the bracket in position in such cases I fit the clamping parts over thc pipes 3 either above or below the point at which it is to be finally located and where no core-piece will interfere with springing the pipes slightly, as is necessary in order to get the parts 17 and 18 in place unless they are slipped over the top of the mainmast, which latter course is not so convenient. After getting the pipes 3 of the mainlnast into the grooves 19 of the parts 17 and 18 I slip said clamping parts vertically into position, and then by screwing up the nuts 24 I clamp them securely in place. I preferably locate the bracket 8 some distance below the top of the mainm ast, so as to leave room for the crosstree and braces hereinaf ter described.

The top of each of the clamping portions 17 and 18 of the bracket 8 is preferably provided with the outwardly-extending flanges 25, preferably pierced by holes 26, to afford means for attaching to said clamping portions 17 and 18 tie-rods 27, whose upper ends are preferably provided with hooks 28, which are inserted into the open upper ends of the upper cluster of pipes 3 of the mainmast, and whose lower ends 29 are preferably `screwthreaded and passed down through the holes 26 of the flanges 25 of the bracket 8, and their withdrawal prevented by means of nuts 30.

The rods 27 assist the clamping portions of the bracket 8 in preventing the bracket from being pulled or forced downward out of its proper position on the mainmast. As will be obvious, the particular methods of securing the tie-rods 27 to the m ainmast and the bracket 8, respectively, may be Varied in many ways Without departing from my invention. The methods shown are simple and effective.

Beneath the flanges 25 of the bracket 8 I preferably form on or connect to the clamping portions 17 and 18 a series of lugs 31, preferably four in number. These lugs are each preferably pierced by eyes 32, and respectively have attached thereto guy- ropes 33 and 34, which extend to the ground at an angle and have their lower ends secured in place in any suitable manner. These gu y-ropes perform the double function of assisting in preventing any upward movement on the part of the bracket 8 and of holding the mainmast 1 vertical.

The Asupporting-arm 19 of the bracket 8 preferably consists of a rib 35 and a sole 36. The sole 36 is preferably provided with a socket or step 37 for the reception of the lower end 38 of the topmast 2. The step 37 is formed in a part 39, which is preferably rounded on its under side, as shown, and preferably contains beneath the step or socket 37 a cavity 40, drained by a passage 41 for the escape of any moisture which might otherwise accu mulate in the cavity.

The sole 36 is preferably pierced by boltholes 42 to enable vertical braces 43, hereinafter more particularly referred to, to be attached thereto. The means of attachment shown are eyebolts 44, but any other suitable means may be used.

The crosstree 9 preferably surrounds the mainmast 1 above the bracket 8. Its frame preferably consists of a hoop 45, braced transversely by means of braces 46 and 47, 48 48, and 49 49. The braces 46 and 47 preferably extend across the hoop 45 and are preferably bolted at each end to the hoop. They are preferably arranged some distance apart and with sufficient curve or bow at their respective middles 50 to snugly span the mainmast on opposite sides. A rlhe two braces 48preferably extend at right angles from the outer sides of the brace 46, one on each side of the mainmast, to the hoop. Their inner ends are attached to the brace 46 and the outer ends to the inner side of the hoop 45 preferably by bolts.

The bolts 51 51, by means of which their inner ends are fastened in' place, preferably respectively passthrough sleeves 52, arranged close to the mainmast and by which the braces 46 and 47 are held apart, and said bolts are passed through the brace 47 as well as the brace 46, and they and their respective nuts 51 preferably secure the inner ends of the braces 49 to the brace 47 as well as the braces 49 to the brace 46. The braces 49 extend on the topmast side from the brace 47 at right angles to the inner side of the hoop 45, to which their outer ends are secured, preferably, by bolts 53, and their inner ends are preferably secured in place by the bolts 51 and additional IOO IIO

vthem and said mast.

fastenings 54, substantially as shown. These braces are preferablycurved or bowed outward in opposite directions at 58, so as to permit the lower end of the topmast 2 to pass between them and at the same time to enable them to partially span or surround it, but preferably some space should be left between They are preferably braced apart by means of sleeves 55a, arranged on opposite sides of the topmast and adjacent thereto, and prevented from spreading by bolts 56, passing through side sleeves 55, and nuts 57, screwed onto the ends of said bolts. The curved portion of each of said braces 49 is preferably pierced by screw-threaded holes 58, through which set-screws 59 pass. When the lower end of the topmast is stepped in the bracket 8, it may be adjusted in an exactly vertical position by means of the set-screws 59, whose inner ends rest against it.

Eyebolts 60 are preferably attached to the hoop 45 of the crosstree 9. The weight of the crosstree is preferably supported by four ties 61, one running from each of said eyebolts 60 to a brace 10. This brace preferably consists of four pieces 62 62 and 63 63. The short pieces 62 are bent so'as to fit around the mainmast snugly and their ends are turned so as to extend out from the mainmast at an angle, and are pierced by bolt-holes. The longer pieces 63 are bent near their inner ends into oppositely-extending curves, adapting them to fit around the mainmast 1, and their extreme inner ends are bent so as to extend out at an angle and pierced by bolt-holes. These sections of the brace are bolted together and clamped tightly around the mainmast and topmast by means of bolts 64, having nuts 65.

From the mainmast 1 the parts 63 extend outward, first parallel to each other and then curve away from each other at 66, and back toward each other again, so as to span the topmast 2. Their'extreme outer ends are bent outward parallel to each otherbeyond the mast at 67 and are bolted together by a bolt 68. Between the topmast and the mainmast the parts 63 63 are preferably bolted together by bolts 69 and 70, passing through sleeves 71 and 72, which brace the part-s 63 apart, and are secured in place by nuts 73.

The ends of the sections 62 and 63 of the brace 10 are preferably not brought close together by means of the bolts 64 and 68, but are separated by a small space, into which eyes formed on the upper ends of the ties 61 are inserted, and through one of these eyes each of said bolts passes, as shown most clearly in Fig. 10. This is a convenient way to secure the ties 61 to the brace 10, but I do not -wish to be understood as confining my claims thereto. The under lower edge of the portion ofthe brace 10 surrounding the mainmast rests upon a band7`, which is preferably exactly like the bands represented in Figs. 2 and 13. This band has its ends bolted together by a bolt 7C and is in that way clamped tightly in place. To enable it to prevent the upper ends are preferably fastened in the eyes of the bolts 60 and which extend thence downward and inward to a band 7a. This band has preferably four eyes 75 riveted thereto, and in these eyes the lower ends of ties74 are fastened. The band 7 is prevented from rising by means of rods 76, having hooks 77 at their upper ends', and which extend up between the band 7LBL and the mainmast and hook over said band. They thence extend downward to the coupling 5, Fig. 22. Their extreme lower ends are preferably bent outward at right angles. They pass down between the coupling and the mainmastthrough recesses 78 in the coupling a short distance, and the bent portion projects outward through holes 7.9, preferably substantially horizontal in said coupling.

Between the crosstree 9 andthe band 7'b the topmast-brace 11 is preferably located. It is preferably composed of two pieces 8O and 81, bowed or bent near their ends inopposite directions and having their ends bolted together. The bowed portions at their inner ends embrace the mainmast, and the bowed portions at the outer ends embrace the top.- mast. They are preferably prevented from spreading by bolts 82, passing through them, and sleeves 83, bracing them apart and ranged between the masts. Said bolts are each preferably provided with a nut 84, by which it is held in place.

The topmast 2 is preferably composed of several sections of pipe 85, whose ends are attached together. Preferably the sections IIO decrease in diameter as the top of the mast is formed by means of metal sleeves thoroughly` The joint not thus formed is fitted in place. preferably located about midway between the ends of the topmast and enables the mast to be divided into two pieces for convenience in transportation. It is preferably formed by the use of a tubular coupling 86, composed of two members or parts 87 and 88, provided at their inner ends with annular iianges 89, adapted to rest against each other, andl boltholes 90, adapted to register with each other and permit the passage of bolts for fastening the parts of the coupling together. Each is screw-threaded internally from its inner end outward for a portion of its length and is provided with a plain extension or flange 91, extending from the screw-threaded part out and adapted to brace the sections of pipe and take the strain off lthe screw-threaded A portion.

The upper member 89 of the couplin gis preferably provided with recesses 92,each adapted to receive a bolt-head and prevent its turning. The lower member 88 of the coupling differs from the other in the absence of the recesses 92 and the presence 0f perforated lugs 93. In using the coupling the upper section of the staff is screwed into the upper member 89 and the lower section into the lower member 8S, as shown in Figs. 14 and 19. The flanges S9 of the parts of the coupling are then arranged opposite each other, so that their boltholes register, and bolts 94, passed through said bolt-holes, and the parts of the coupling drawn together and securely held in place by nuts 95, screwed onto the ends of the bolts. The Vertical ties or braces L13, hereinbefore mentioned as being secured at their lower ends to the sole 3G of the bracket 8, extend up to the coupling 88. Their upper ends are preferably forked and perforated and are secured to said lugs 93 of the coupling by means of bolts 95.

About midway of that portion of the topmast below the coupling S8 I preferably arrange a spreader, consisting of a ring or band 97, surrounding the mast, and four arms- 98, extending out radially therefrom, preferably at right angles, and each preferably forked or grooved at its outer end, and over the outer end of each arm passes one of said vertical braces or ties L13, which prevents the lower end of the topmast from rising from its socket or step 37.

The spreader is held in place by means of screws 99, passing through the band 97, and preferably entering holes 100, tapped in the topmast.

Near the top of the topmast it is preferably encircled by a band 101, attached in place by welding or otherwise, and immediately above this band the topm ast is preferably encircled, where it is to be used as a flagstaff, by a ring 102, turning loosely upon the mast and supporting an outwardly-extending yoke 103, rigidly attached thereto and carrying a sheavewheel 104, having an axle 105, turningin bearings 106 in said yoke.

The topmast is surmounted by a cap-piece 107 in the shape of a ball tapped so as to permit of its being screwed onto the top of the topmast, which is screw-threaded to receive it.

The lower end of the topmast is preferably provided with a ring 108, welded thereto, and having one or more rings 109 attached thereto for convenience in hoisting.

One of the guy-ropes 34k is useful for forming part of a ladder as well as for supporting the mainmastin position. From the gu y-rope 34 another rope 110 branches off a short distance above the ground and extends up parallel with the rope 34 from the point where the lowermost of the ladder-rungs 111 is inserted, and is attached at its upper Aend to the eye 112 of the bolt 113, passing through the crosstree-braces 48 11S, and a sleeve 114, extending across between said braces and said bolt, being secured in place by means of a nut 115.

The construction shown in the drawings is the one preferred, and has accordingly been described in detail; but I do not wish to be understood as confining my claims to the precise forms of mechanism shown and described, as they may be greatly varied by the substitution of equivalents without departing from the substance of my invention.
