. This invention k'relates''to-sailing vessels and has particular reference to an improved rigw ging therefor. 1

' The ii'iventi'on consists'in an improved rig- 5 ging' for vfore-and"-a'ft"` sailing vessels, particularly' schooners,.and coinprehends afrigging by means of which a rearrangement of the total sail areais had, with a view of ob taining better sailing qualit-ies when traveling 'to' windward and V'a larger and more effec- I tual sail area when running before the wind.

" lIt is` a well-known` and 'established' fact that a. le'g-ofmutton sail is ino-re efficientv and, furthermore, v'that leg-of-mutton sails Yhavetlie advantage thatin'jibbingthere is a less area and1 mass 'of sail' to swing over from starboard tocport, or vice versa, land hencev the strain to which the' boom and sheets are subjected, is minimized. lt"is,'ho\vever,A

. obvious vthat there' is ajloss of sail area in a,

leg-oflmutton sail over a' gaif sailg'an'd, therefore, the present invention contemplates as a further object, the provision vof an improved upper rigging, which' in'addition to com,-

pensating for this apparent loss, affords an auxiliary or supplemental sail area,the' combinationA of which exceeds the sail area of agafsail'ig. The invention further-more and more specifically embodies anv upper rigging'including ayard on eachA finastequipped' with four triangular sails'7 namely, two'upper top-sails and' two .lowerfyardrsailis,1 one of reach of which is l respectivel'y disposed 'to *starboard l vand po'rt,"whe1e`by the'advantag'e of'v'h'aving a total increased'sail areadistri'buted amongvv a 4greater number 0f smaller sails`V isV obtained,

thus rendering the liaiidliingofthe rig'easier 4oV and necessitating a smaller crew'in yproportion'to the total sail area. I 'j y vFurther.A objects and advantages derived from the improved rigging reside inthe' at taining of a greater and more efficient driving power when traveling towind'ward for the-reason that yards can .be braced farther around than `in a square rigged ship; but due to the employment fof" a. larger number yof smaller sails, the same can beheldmore 5 firmly tothe wire rope stays, :thus affording an. excellent opportunity tojgain the vbest driving: force therefrom.

,v Thefparticular rigging" furthermore affords an unusually large amount of cutting edge, and as soon as thewind has exerted its full force vagainst.` the triangular top and yard sails ofvwhiclr it is composed, it passes' awayy at the leech without interfering with the lu'if ofthe next'adjacent sail.

The' inventionl Jfurthermore embodies an improved ri-gging'which affords a larger sail area for light orstrong winds, which area is more` readily adjustable as welll as steadier, and more effeetu'ally ldistributed asi a storm.- rig; a rigging which is easier handled` due' to the fact that when tackling thelnecessity oflowering' the topsa-ils'is obviated;A anii'pperrigginglprovided withl means for facilitating the furlingv or un-furling, thereby entailin'gl economy intime and labor, and rigging which is comparatively simple, inexpensive and eiiicient.

W'ith the aboverecited and other objects in'`l view, reference isliad to the following specification, and drawings, in which therey is' exhibited one example yor embodiment of the invention which is in no Way inten'dedfas a `limit-ation upon .the scope of the appended claims as it isto beclearly understood that variations andv modifications which properly fall within the scope of saidclaims may be resorted to when found expedient.

.The invention resides particularly inthe upper rigging, which includes the topmast 15, the yards 16, a pair oftriangular' shaped starboard' and

port topsails

17 and 18,'Y anda pair of triangular 7starboard and port yard'- sails19 and 20. The topmast l5 is' mounted at its lower `end in 'a tooni'ast-step2l and is alsosecuredjaty vertically spaced points by clips 22 and23y tov the top of the lower 'or the topmast 15.

, upper horizontal edge 47 of each yard-sail.`

mainmast. The yard 16 is mounted for horizontal and vertical swinging movements in a swiveled summit yoke 24 mounted in an eyebracket 25 on the lower'olip 22. The yard is further supported and braced by vertical st-ay lines 26which extend upwardly and are respectively connected to the upper and lower topsail stay

arms

27 and 28, the tormer being pivoted for vertical movement at 29 in a hanger 30, which is swiveled at 31 in a bracket clip 32 secured ,to the upper end ot The latter lower topsail stay arm 28 is pivoted at 32 in a stirrup 33 which is swiveled at 34 in an eye-bracket 35 onthe top clip 23. The

topsails

17 and 18 have their vertical inner edges 36v which form the altitude ot the triangle, provided withvguide rings 37 threaded upon or embracing the stay-lines 26. The upper end or apex 38 4.of/each sail has connected thereto a rove halyard 39 trained overan outer block 40 and an intermediate block 41 on the upper ystay arm 27 for the purpose of raising or unfurling the topsail. The means Jfor spreading the topsails laterally consists of a spreader-line 36IL connected to the outermost point 37 a of each topsail and trained over a guide eye 38a and around blocks 39a on the yard 16. l n

ln order to provide means for urling the topsails, a clew-line 42 is connected at its upper end to the vertical stay line 26, and each clew-line is trained through the lower guides 43 adjacent the lower edge ot' the sail, and vertically spaced marginal guides 44 lon the outer inclined edge 45 of each topsail. From the uppermost guides 44, the topsail clew lines 42 extend downwardly to the deck.

, The yard-

sails

19 and 20 are suspended from or carried by hoops 46 threaded upon the yard 16, said hoops being attached to the The yard-sails arel hauled outwardly by means of outhaul-lines 48 connected at their upper ends with the outermost hoops 46 and trained around blocks 49 at the outer ends of the' yard 16. The outhaul-lines 48 are trained around'blocks 50 carriedr adjacent the medial portion oi' the yard 16 from whence they lead to the deck.

` The yard-sails 19 and 2O are hauled inwardly or furled by means of buntlines 51 which are connected by bri'dles 52 to' the outer vertical edges 53 of the triangular yard-sails at vertically spaced points. The buntlines are trained around blocks 54 atz tached to the vertical shrouds 55 of the maintical rocking movements by yard topping stays 58, which are connected at their opposite ends respectively to an eye 59 on the topmast 15 and to the outer end of the yard smaller crew can be carried and the diliicult'.

task ot reeting in heavyweather is avoided since the shortenin of the sail can be done entirely by the leads which pass down'from the various sails to the belaying pinsv on the deck. f

It will be further noted that more driving eliiciency out of the sail spread when going to Windward is obtained, for the reason that' not only can the yards be braced further around than in a square rig ship, but the system oi' employing a plurality of small tri-j' angular sails held lirmlyto the wind on wire" rope stays, alords an excellent opportunity to obtain the' best driving vforce from these' sails.

It will be further observed` that by positioning the summit yoke well forward of the;Y

mast, it becomes possible to swing the yard with its sails around and trim the sails in the most advantageous manner to catch the wind when the ship is beating to Windward.

By means of the rigging disclosed'vit is obvious that in a Seaway with a light breeze, top sails may be carried, while the rigging gives a larger, lighter and stronger ".wind sail area, more adjustable to conditions, as well as a steadier and better ydistributed storm rig. In running before the wind, it will be seen that the rigging, due to the additional triangular yard-sail and vtopsail, gives practically the same amount of canvas as a gal' sailrwhile the remainingytopsail and yard-sail, afford two extra sails, thereby increasing the total sail area.

The aforementioned advantages are all compared with a schooner which the present rig resembles the most.v

If desired, power for hoisting' the sails may be employed without in any way departing from the scope of the invention.
