' To all 'whom 'it may concem;

`Be it knownthat I, ALoNzo T. PHILLIPs, a citizen of the United States, residing at Norranma the County ofNorfolk and State of Virginia, have invented new and useful Imrovements inPropellers, of' which' the folowing isa speoification. v

This invention relates to the propulsion of vessels by wind power; and it has particular reference to that class of devices inwhich the power-of the wind is utiliz-ed for the purpose of in ,arting motion to one or more screw prcpe ers the principal objects of the invention being to utilizetthe force of the wind from any direction without the necessty of setting or adjusting the sails to economize -labor in the handling of the vessel; and to reduce the danger of capsizing as Well asof injury to the Operating mechanism in squalls and heavy Winds.

v Further objects ot' the invention are to provide sim le and improved means for rep versing the irection' of movement, when desired, and to 'simplify and improve the gen- :eral -construction and operation of this clas's of devices.

With these and other ends in view which will readjly appear as the nature of the invention is betterunderstood, the same consists in the improved Construction and novel arrangement and combmation of parts which will be hereinafter fully described and particularly pointed out in the olaims.

In'the acoompanying drawings has been illustrated a simpleand preferred' form of the invention; it' being, however, understood that no limtation is necessarily made to the recse structural details therein eXhibited,

ut that changes, alterations and modifications within the scope of the invention may be resorted to When desired.

In the drawings, Figure 1 is a sectional elevation of a vessel equipped with propelling i mechansm in accordance with the principles of the invention. Fig. 2 is a detail plan view of the mechanism for transmitting motion to' .the propeller shafts. F ig. 3 is a sectional`elevation illustrating a modified form of the invention. Fig. 4 is a seetional detail view, enlarged, taken on the line 4-4 in Fig. 3.

Corresponding parts in the several figures e are denoted by like characters of reference.

A designates the hull and B the deck of a vess'el which may be. of any desireddimen 'sionsand of any suitable Construction.

plane indicated by the p A mast 1 issteped in a bearing 2 in the lower part of the hu and an additional bearing 3 for said mast is provided in the deck of the vessel. 'The mast carries a horizontally disposed wind motor &which in its preferred form is made of canvas or other suitable textile or "l'lexible material supported .on a franie somewhat likean umbrella frame and which, when eXpanded to the action of the wind, includes a plurality of folds forming pockets 5 'opening imone direction. Guy or brace rocls 6 connect the rim of the motor with a runner consisting of a sleeve`7 which travels upon the mast for`0pening and closing the motor and which may be adjusted upon the mast by means of blooks 8 and tackle 9. As illustrated in the drawing, the blocks and tackle may be utilized for elevating the sleeve or runner 7, and the latter will be lowered by gravity; but it is obviously within the scope of the invention to utilize mechanical means of any well known description for positively lower'ng the sleeve or runner in order to fold the motor, when desired.

Under the Construction illustrated in the 'several figures of the drawings twin propeller screws '10 are employed, the same being mounted upon the rear ends of horizontally disposed shafts 11, arranged parallel to each other and supported for rotation in suitable bearin'gs 12.,

Under the construction illustrated in Figs. 1 and 2 of the drawings, the nast carries a sprccket wheel 13 from which motion is transmitted by a link belt 14 to a sprocket wheel 15 ,upon a vertically disposed shaft 16. A horizontal shaft 17 is slidably supported in suitable bearings 18 and 19, and said shaft 17 carries oppositely disposed bevel gears 20 and 21 adapted for alternate engagement with a bevel gear 22 'upon the shaft 16. Vertically disposed shafts 23 and 24 are stepped in suitable bearings intermediate of the propeller carrying shaft -11, which latter are driven by the shafts 23 and 24 through the medium of sharply pitched worms 25 and a 'worm gear 26. The shafts 23 and 24 are themselves driven by the shaft 17 which rotation of the pro alternately in mesh with the bevel gears 29 and 30 inorder to reverse the direction of eller carrying shafts. Hingedly supported ocking devices 33 are provided for the purpose 'of 'securing the shipping lever and the parts operated thereby at 'various adjustments; said looking de vices being mounted ad'acent to a slot 34 in the deck through whic the handleof the shilpping lever projects.

t willbe seen that by the. construction just described motion Will be transmitted from the mast to the propeller carrying shafts, and'said motion may be nstantaneously reversed when desired for the purpose of reversing-the direction of movement of the vessel;

Under the modified Construction 'i1lustrated in Figs. 3 and 4 of the drawings, the mast is provided with two sprocket wheels v 35 and 36 which are connected by link belts 37 and 38 with sprocket wheels 39 and 40 that 'are formed upon sleeves 41 and 42 which are loosely journaled upon shafts 43 and 44 that are stepped in suitable bearings intermediate of the 'propeller carrying shafts with which the saidvertical shafts are connected by oppositely disposed worm ea'ring 45 .and 46. Suitably constructed shown at 47 in Fig. 4 of the drawings are 'provided' for the purpose of connecting the sleeves 41 and 42, transmission of motion to tle" propeller carrying shafts may be interrupted, when desired. It .willalso be 'understood that ,the longitudinally slidable shaft 17 in Fig. lof the drawings may be so adjusted, when desired, as to throw both sets of bevel gears 27 and 28 out of mesh with-.the

..bevel gears 29 'and 30, thus interrup-ting'the.

transmission 'of motion-.when desired.

` From the foregoing description taken in connection with thedrawings h'ereto annexed, the operation and advantages of this inventioh will be readily understood and appre- *ciated It is obv'ious that the propellers may be continuously. operated without regai'd -to' the direction of the' wind and without necessity 'for attending to the winddriven motor beyond adjusting the latter so' as toexpose more or less surface to the action of the wind according toithe forceof the latter and to the speed thatit is desired to attan'.

While 'in the accompanying drawings only a single mast has been shown, it isobviously within the scope of the invention to use any desired number of' masts, each carrying. a motor, the means for transmitting motion to the propeller carrying shafts being suitablv modified as will be readly understood. t

is also evidentthat the size; proportion, and

exact assemblage of the parts of the invention may be changed and modified without de arting from the spirit of the invention.

aving thus fully described the invention, whatI claim as new is 1. A shaft supportedfor rotation and carrying a screw propeller, a mast stepped for rotation, a fl'eXible foldable motor wheel supported upon the mast, a sleeve 'slidable upon guy members e'onnecting the the latter, sleeve with the rim of the motor wheel, means for adjusting the sleeve upon the mast and means'for transmitting motion from the latter to the propeller carrying shaft.

72. A shaftsupported for rotation and carrying ascrew pro'peller, a .mast ste 'ped for rotation,` a flexible foldable motorw ported upon the mast, said motor wheel comprising a' plurality of angular pookets, a.

a le upon'the latter,-brace" `rodsco neeting the sleeve with the rim of the :motor wheel, means for adjusting the sleeve upon' the mast and means' for transmitting motion from the latter to the propeller carrying` shaft.-

In testimo'ny whereof, I' affix my signature' in presence of two witnesses. r i ALONZO T. PHILLIPS.
