MAST FOR STEAM VET'SSELS;

SIZECIFIGATION forming part of Letters Patent No. 655,707, dated August 14, 1900.

To all whom it may concern.-

Be it known that I, \VILLIAM C. HAYNES, a subject of the Queen of Great Britain, residing at Glasgow, Scotland, have invented certain new and useful Improvements in Masts for Steam Vessels, of which I declare the following to be a full, clear, and exact description.

As steam-merchantmen are nowconstructed they are provided with one or more masts, each of which is a round tapering spar of wood or metal. A mast of this shape, while indispensable in a'sailing vessel, where sails are to be raised and lowered, is inconvenient and cumbersome in a steam vessel, especially so when it is necessary to add, the booms, yards, windlasses, and other mechanism used in Loading and unloading the vessel. These booms or yards are usually pivoted or hinged at or near the deck of the vessel and grouped around the mast, the blocks and halyards by which their movements are governed being attached or connected to the mast. Many objections might be pointed out in this construction; but I will not attempt to enumerate all of them, merely calling attention to the fact that the deck is encumbered both by the masts and by the booms; that their lower ends are awash whena heavy sea breaks over the deck; that the booms, being pivoted near the center of the deck, have to be of considerable length to reach over the side of the vessel, and that their outboard playisnecessarily limited. Then, too, the hatches,which usually are situated near the lower ends of the booms, must be provided with removable covers, for if hinged hatch-covers (which are more desirable) were used they would interfere when opened with the swing of the booms.

These removable hatch-covers are particu-' vided with masts made according to my in vention, and'Fig. 2 shows a side view of one mast and Fig. 3 an end view of the same.

My invention consists in substituting for the ordinary mast made like a tapering shaft a derrick-like structure of open-Work, which maybe made of end pieces, as AA, the lower ends of which are fastened at or near the sides of the vessel and which extend obliquely inboard to the cross-piece B. This structure may be strengthened by crossbraces, if desired, and it will be found that a uniform height of, say, fifty feet will be suitable for modern vessels, of whatever style. Somewhat above the deck of the vesselabout nine feet I have found to be mostconvenient--I provide a platform D, upon which are mounted all the windlasses or winches and the levers, &c., by which the operative parts of the mechanism are controlled, as I shall describe. At any suitable positions upon this platform and preferably near the sides of the vessel I mount one or more cranes or Outriggers E E. Each of these is provided at its lower end with a ball-and-socket or other universal joint, so that the end of the boom maybe raised or lowered or swung in any direction. Ropes or guys F F are provided, by which the movement of the outer end of the boom is controlledby steam or other suitable power. The tackle for raising the cargo which is to be transferred upon the guys is opera tively connected to a steam or other winch H, which is mounted upon the platform D. Each of the other booms E is likewise mounted upon and operated from the platform D, and, if desirable, pairs of booms may be operated from the same Windlass in the well-known manner, as is shown in Fig. 3.

As it may be desirable to change a boom from one Windlass or winch to another, I provide a chain J from side to side of the structure A A, the links being large enough to hook suitable blocks K K upon them. By firstrunning the rope G of the left-hand boom, Fig. 2, through block K and then connecting it to the central Windlass H that boom can be operated from the central Windlass.

It will be understood readilyby those skilled in the art that the present objectionable hatchcovers to which I have referred may be done away with, and in their place hinged covers connected to each of the masts which I have described heretofore. The object of these guys M is to help to steady the masts A A and to extend the range of operation of the loading-tackle. This may be done by fitting these guys with travelers or trolleys, or at suitable points I may provide them with stationary blocks N N, from which ropes may eX- tend toward the booms, as shown near the right-hand mast of Fig. 1. In this way bales of goods or other cargo may be swung toward the center of the vessel (from stem to stern) beyond the limit of movement of the booms E.

All the details of construction which I have outlined are susceptible of endless variation Within the limits of my invention and I do notintend to limit myself in any way to them. Nor is it important that any particular materials be used in constructing the various parts of my apparatus. Fore-and-af t sails may be rigged upon my masts just as upon the old tapering spar-masts.

In the drawings I have shown the platform D as being partially supported by posts mounted upon the deck of the vessel. This may be done, if desired, but it is generally preferable to support the platform by the structure A A alone, the posts being omitted.

It should be understood that the structure whichIhave described and illustrated herein is permanently and rigidly secured to the hull of the ship, so that it becomes a part of the ship itself as truly as an ordinary mast. is a part of a ship to which it is applied, and, further, that the several parts of the structure are arranged and disposed with refer-, ence to their being a part of a ship. Thus the platform is so disposed relative to the deck of the ship that there is ampleospace un-' der such platform for all duties required to be performed on the portion of the deck covered by such platform and so that at the same time the loading-cranes which are mounted on the platform are above the bulwarks of the ship, and thus can freely operate over and across them.

What I claim as my invention is- 1. The combination with the hull or body of a steam vessel having a continuous deck in which are formed hatch-openings provided with hinged hatch-covers, of the open-work structure of framework having its ends secured to the hull near the opposite sides thereof and extending transversely across the vessel, a platform arranged above a portion of the deck at such distance therefrom as to permit free movements on the deck, and arranged between the endsv of the said openwork structure, and loading-cranes mounted on said platform and arranged to swing vertically, and horizontally over the hatch-openings in the deck of the vessel and outward over the sides of the vessel, substantially as described.

2. The combination with the hull or body of a steam vessel having a continuous deck with hatch-openings therein, of a plurality of masts each consisting of an open-work structure having its ends secured to the hull near the sides thereof and extending transversely across the vessel, platforms supported above the deck of the vessel and between the ends of the said open-work structure, cargo spans or stays running fore and aft the vesseland connecting the upper portions of the said mast structure, travelers or trolleys upon the said spans or stays whereby the cargo may be carried from the platforms to the hatchways near the center of the vessel and vice versa,

and loading-cranes mounted upon the platforms adapted. to swing horizontallyover the sides of the vessel.
