Application filed January 18,1904. :Serial No. 189,401. (No 'model.) I

To all whon it may concern:

Be it known that 1, WILLIAM WIL IAMs, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Means for Working Ships, of which the following is a specifica tion.

My invention relates to improvements in means for working ships, the object of my invention being to provide an apparatus of this character which shall render it easier to set and trim ships sails and enable it to be done more quickly, requiring a smaller crew and dispensing with the necessity of ascending the rigging, but enabling the whole of the .operationto be performed from the deck of the ship.

My invention also has for its object to provide an apparatus of this character which will hold the sails in a better position to catch the wind, thereby rendering them as efficient as possible, one, moreover, which shall be more economical, effecting'a saving in the cost of cordage.

My invention therefore resides in the novel construction, combination, and arrangement of parts'for the above ends hereinafter fully specified, and particularly pointed out in-the claims. 4

In the accompanying drawings, Figure 1 is a perspective view of a rear portion of a ship, a portion thereof being broken away. Fig. 2 is a similar view, on a larger scale, showing the lower portion of the mainmast and of the topmast. Fig. 8 is a horizontal section through the roller-carriers for the inner edges of the Fig. 4: is a broken front view of the upper portion of the masts and the sails car ried thereby. Fig. 5 is a broken plan view of the end of one ofthe sails. Fig, 6 is a horizontal section of one of the outside rollercarriers. Fig. 7 is a plan view of the end of the mainyard. Fig. 8 is a broken side view of the topmast, the yards beingsh-own in section. Fig. 9 is a plan view of one of the double conical windlasses.

In the drawings I have illustrated my apparatus in connection with a single mast; but it will be understood that the same applies to each of the principal masts of a ship.

' I will first describe thenovel means which I use for squaring and trimming the sails. For this purpose to the ends of the boom 1 of the mainmast 2 are attached the main-sheets 3 and the main-tacks 4, the latter passing around forward sheaves5, and the sheet and tack from each end of the boom passing in opposite directions around a gipsy or windlass 6 on the ships deck near the side. Upon turning either Windlass 6 in one direction the sheet on thatside will be wound in and the tack let out, while at the same time the windlass on the other side is being wound in the opposite direction to let out the sheet and wind up the tackon that side. This swings the boom around the mast. I To the ends of the mainyard 7 are attached braces 8, which pass around sheaves 9 on the deck close to the stern, thence around sheaves 10, and thence pass to a gipsy or Windlass 11 in the center of the deck", upon which they are wound in opposite directions.

Each of the gipsies 6 and 11 is of a double conical form, narrow in the center, and each of them at one end carries a gear-wheel 12,

which engages a pinion 13, which is screw threaded on the inside and acts as a worm-.

wheel turning on a worm 14, so that as the Windlass is revolved the revolution of the pinion causes it to travel longitudinally upon the 4 worm. The pinion is contained within the fork 15 of a leg16 of a bearing for the windlass, the other leg, 17, of said bearing traveling upon a rail 18. Said fork islikewise connected with the leg of the forward bearing 19 by means of a longitudinal bar 20. 'Thus the longitudinal movement of the pinion imparts a corresponding movement to the bearings of the Windlass and causes the whole windlass to travel longitudinally upon the worm. The object of this construction is to keep the braces and sheets and tacks taut, as the sail is trimmed from a position square to theship to one close-hauled. The sums of the distance of the ends of the yard and boom from the windlasses differin these two positions, so

that it is necessary to take upthe slack in making the change.

To the lower topsail-yard 21 are attached braces 22, which pass over sheaves 23, supported upon the jigger-mast 24:, thence to a windlass upon the deck, around which they are wound in opposite directions. In the same manner the upper topsail-yard 26 has braces 27, passing around sheaves 28 on the jiggermast and thence to the windlass 29. By turning are furled by being rolled up and are unfurled by being unrolled. The mainyard 7 is suspended at the center from the mainmast and is also secured to a collar 30 around said mainmast. The lower topsail-yard 21 is secured to a collar 31, which revolves on ball-bearings 32 around the topmast. Both the mainmast and the topmast 33 are of steel and hollow. The upper topsail-yard 26 is supported in like manner by a collar 34 upon the topmast. This collar 34 is, however, slidable upon the topmast for the purpose of furling or unfurling the upper topsail. All of-the sails are made in two halves, one half on each side of the mast, each half being independently rolled upon a sleeve substantially the width of the sail upon the corresponding yard. The two halves of the mainsail 35 are rolled upon sleeves 36 upon the mainyard, the two halves of the lower topsail 37 upon sleeves 38 upon .the lower topsail-yard, and the two halves of the upper topsail 39 being wound upon sleeves 40 upon the upper topsail-yard. In order to roll up the sails successfully, it is essential that they be maintained flat and taut while being rolled up, so that the edges do not wrinkle and overlap. For this purpose there is provided for each sail over against the sleeve on which it is being wound a straight strip 41, the inner or middle portion of which is movably secured to the central,

guide 42 for the sail by a bolt or pin 43, being pressed thereto by a spring 44, while the outer portion is movable horizontally from the end of the yard, a spring 45 pressing against the head of a slidingbolt 46, the other end of which bolt engages the end of the strip 41, normally pressing said strip against the rope which forms the edge of the sail, while allowing the strip to move outward from the yard as the sail is being rolled up and increasing in thickness. On the lower portion of the enlarged end of said strip are secured the roller-carrying arms 47, connected by a spring 48 and carrying rollers 49, which bearagainst the inner edge of the rope 5O, forming the edge of the sail, and hold said rope in its proper position. these devices for the upper and lower topsail- Such is the construction of yards. The construction for the mainyard is the same, except that instead of the spring 45 on the rear side of the yard there is a spring 51 around a bolt 52 upon the forward side of the yard. The inner edges of the sails are maintained straight and taut by moving between carrier arms 86, hinged upon the central guide 42 and drawn together by springs 53, said arms carrying rollers 54, which engage the rope forming the inner edge of the sail. For the mainsail and lower topsail the lower inner corners have eyes 55, sliding upon steel bars 56, and the roller-carrying arms 52 are stationary; but for the upper topsail said arms are movable, being connected by flexible bands 57.

The sails are furled and unfurled in the following manner: To the inner ends of the revoluble sleeves on the yards are rigidly secured the roll-up channels 58 for the chains. 59 represents a winding-up Windlass for winding up the chains for furling the sails, which chains pass around the roll-up channels 58. This windlass 59 is connected by beveled gear and a transverse shaft 60 with another windlass, 61, which is used for unfurling the sails. For this purpose there are provided for each half of the mainsail two chains 62 63, one of which passes around a roller 64 and thence to the inner cprner of the foot of the sail, and the other passes around a sheave 65, secured to the lower end of the guide 42 for the lower topsail, thence around a sheave 66 on the mainyard, thence around a sheave 67 on the .end of the boom, and thence to the outer lower corner of the sail. By winding up this latter windlass both lower corners of the mainsail are drawn down to the boom. This boom consists of two pieces of metal spaced from each other to allow the foot of the sail to pass in between. In order to hold the foot of the sail firmly down against the strength of the wind, there is provided a key or clutch 68, which can be moved inward to engage the chain and hold it down, said clutch having a stem 69,-which passes through eyes 70, secured upon the main-boom, and is bent out- IIO ward at right angles at its inner end in order to more conveniently operate the same from are wound upon sleeves upon the lower topsailyard by means of the roll-up channels 58, around which are wound chains 75, which pass through the maintop 76 and ca n then be at- 'the sleevesto roll at the same time. this purpose the chains 85, which pass around ae y o tached to the Windlass 59 for winding up the same. After being wound up they are attached to claw-hooks in the same manner as those for the mainsail. The lower inner corners of the lower topsail are attached to chains 77, which pass around pulleys 78, secured upon the central guide, and thence around pulleys 7 9, carried in the end of the mainyard, thence around sheaves 80, suspended from the center ofthe mainyard, and thence down to a pulley 81, thence back to a second sheave 82 in the same block as the sheave 80, thence around a second pulley 83, carried in the end of the mainyard, and thence to the outer lower corner of the sail. To the pulley 81 is secured a chain 8 1, which may be attached to the Windlass 61, so that by winding said Windlass a pull is produced upon both the lower corners of the sail, and the sail is extended. The upper topsails are wound upon sleeves on the upper topsail-yard, and

for the purpose of furling these. sails the upper topsail-yard is drawn down, causing For the roll-up channels 58, extend down to the deck, and upon pulling said chains said channels and sleeves are rotated, rolling up the sails. When the chains 85 are released, the upper topsail-yard is again raised by means of a chain or rope 87 passing over a pulley 88, secured in the top of the topmast 33, thef other end of said rope or chain 87 extending 3 down in the hollow mainmast and being attached to a heavy counterbalance-weight 90 in said mast as low as possible below the deck.

drawn up by means of springs 92,so that their rear ends, extending toward the mast, normally press downward. When the upper topsail-yard comes to the proper height, these levers bear down upon a cross-bar 93, attached to two pawls 94, which are normally drawn upward by springs 95 and force said pawls 94 down into contact with ratchet-teeth 96, carried upon the ends of the sleeves, so that said sleeves can no longer rotate. By this means the upper topsails are prevented from draw- 'topsail-yard has been drawn down as far as possible by means of the chains 85, the yard is then secured against upward movement due to the counterbalance by means of a chain I in proportionto the size of the sails.

Tostretch the outer lower corner of each upper topsail, there is provided a chain 97 attached thereto, which passes around a pulley 98in the lower topsail-yard, thence around a pulley 99, carried by the center of the lower topsail-yard, thence around a pulley 100, near the lower end of the central guide, thence around a pulley 101, carried by the center of the main lower topsail-yard, and thence to the lower inner corner of the upper topsail. To the pulley 100 is attached a chain 102, which leads around suitable direction-pulleys to the deck. Of the three central guides for the sails the lower one (for the mainsails) has its upper end attached to the center of the mainyardand its lower end attached to the extension 7 3 of the frame at a considerable forward obliquity downward. The object of this upward and downward slope is to enable the sails to be swung around when close-hauled to clear the shrouds. The two upper central guides for the sails are both secured to the lower topsail-yard.

It will be seen that with this construction all the operations of working the ship can be performed from the deck without the necessity of ascending the rigging. Therefore a much smaller crew is required, and the ship can be worked with much greater safety in storms. Also the sails can be furled much more quickly than as-at present; This is of especial importance in case of a storm coming on .very quickly. It will also be observed that all the sails are set and held flat and square to the wind, the lower edge of each sail is stiffened by a stiffener-piece 105, and the whole sail when'set can be drawn as tight as if it were a sheet of metal. This provides a sail much more effective in driving the ship.

A further advantage is that there is the saving in the cost of cordage, which at present is a great item of expense in a ship.

It will be understood that while the drawings illustrate only a, single mast of a ship the same principles are applicable to all the masts and also to the upper and lower topgallantsails. The sails of each of the forward masts will be braced from the mast immediately to the rear in the same way as those of the masts here shown are braced from the jigger-mast.
