     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIGS. 1-6 and 8 illustrate the wind powered music machine of the present invention which includes a vertically positioned framework 1 which consists of a longer vertical member 1a, a shorter vertical member 1b, an upper horizontal cross-piece 1c and a lower diagonal cross-piece 1d. A plurality of chime tubes or acoustic members 2a &amp; 2b are vertically suspended from the framework at their top and bottom by means of tied wire or line 3. The chime tubes are tuned by exact length as musical instrument members; C, C#, D, Eb, E, F, F#, G, G#, A, Bb, B, C, etc. and graduating from lower note pitch symmetrically up to higher note pitch. The chime tubes are aligned in two rows; a front row 2a and a back row 2b and in a staggered or offset configuration effectively exposing frontal access to the back row of chime tubes. 
     A hollow rotatable cylindrical body or drum 4, it&#39;s axis being horizontally disposed and perpendicular to said chime tubes, is held fast to an axial shaft 5 by means of a spoke-work 6 and small hub 7 at each end of the cylindrical drum. The axial shaft rotates in two bearings 8 mounted atop said framework. The periphery of one end of said cylindrical drum has a ring gear 9 fixed thereto. 
     The upper portion of said longer vertical framework member 1a is provided with a fixed bearing 10 through which a rotary shaft 11 turns, being held in position by means of common threaded nuts 12. The axis of shaft 11 is directly below and parallel with the rotational axis of the cylindrical drum 4. 
     A propeller 13, of adequate size to power said machine in light wind is removably secured to said rotary shaft 11 by means of a threaded flange nut 14 tightened on the propeller hub 13a. Ample clearance is maintained between the propeller blades 13b and framework member 1a to allow unhindered rotation of the propeller. 
     Fixed to the opposing end of the rotary shaft 11 is a pinion gear 15 engaging and counter-rotating ring gear 9 fixed to cylindrical drum 4 to enable wind acting on the propeller to drive this described mechanism by slowly rotating the cylindrical drum in the correct direction. 
     Equally spaced around the periphery of said cylindrical drum 4 are a plurality of identical rows of small equally spaced holes 16, each row being in vertical alignment with its respective chime tube axis. Inserted into the holes in a predetermined and changeable musical pattern are a plurality of small identical snap-in type pegs 17 that can easily be inserted or removed. 
     As the cylindrical drum 4 rotates, the small pegs projecting radially from and mounted thereon, engage, depress and disengage the upper ends of a plurality of lever hammers 18a &amp; 18b, thereby causing the lower ends of said lever hammers to rise and fall, because of gravity, striking the correct chime tubes in the correct sequence, thus producing the desired song. The lever hammers are of a general crescent or dolphin shape and are pivoted at their upper mid portions 18c while being held in alignment by spacers 19 with respective pegs and chime tubes on a common rod 20 mounted on the framework. The common rod 20 is parallel with the axis of cylindrical drum and adjacent to the lower periphery of the cylindrical drum and the upper portion of the chime tubes. 
     This machine employs two different sizes of lever hammers; a short type 18a for striking the front row of chime tubes 2a and a long type 18b for striking the back row of chime tubes 2b. For the back row chime tubes to be struck, producing the desired musical tones, the long type lever hammer 18b must pass unhindered between the front row chime tubes. The distance from the axis of the cylindrical drum to the upper ends of all the lever hammers is the same. 
     Fixed to the shorter vertical framework member is a vertically positioned directional vane 21 which functions in a known manner to direct the propeller continually into the prevailing wind. 
     The machine is mounted to a firm level mounting surface 22 by means of a vertically disposed pivotal shaft 23 fixed to a bracket 24 which is secured to the bottom portion of the longer vertical frame member 1a. The shaft 25 is inserted into and easily removable from an upper bearing 25 and a lower bearing 26 which are firmly mounted to a vertically positioned fixture 27. The fixture 27 is attached to a mounting base plate 28 which is secured to the firm level mounting surface 22. This mounting base assembly provides unhindered three hundred sixty degree pivotal rotation to said machine and ease of removal of said machine from said mounting base in the event of inclement weather. 
     A cap or cover 29 is fixed around the upper portion of the pivotal shaft 23 and acts as a rain cap protecting the bearings from rust caused by rain or moisture. 
     In order for the user of the machine to more easily determine the correct peg location coordinates on the cylindrical drum 4 to render a given musical composition, a series of longitudinal lines designated by letters 30 and transverse lines designated by numerals 31 are embossed or inscribed upon the periphery of the cylindrical drum in correct alignment with the small peg location holes 16 therein. The letters 30 and numerals 31 correspond with like letters 32 and numerals 33 shown as coordinates in the song-book coordinate list 34 which accompanies the machine as illustrated in FIG. 7. The song-book coordinate lists show the necessary peg placement coordinates to play a variety of songs. 
     The cylindrical drum 4 is hollow with a spoke-work 6 and small hub 7 attached to each end which allows wind to pass through the cylindrical drum relatively unhindered. The employment of a hollow rotatable cylindrical drum substantially larger in diameter and of length will not substantially hinder air flow through the propeller blades. This advantage allows a greater circumference around the cylindrical drum, thereby, allowing a greater number of peg location placement holes per row around the cylindrical drum, thereby, allowing a lengthier song to be played. 
     The machine may be configured with a known belt and pulley drive mechanism, (see FIG. 8). This version utilizes a propeller 35 which rotates in the opposite direction of the aforesaid propeller 13. A small pulley 36, large pulley 37 and a rubber belt 38 engaging said pulleys is an alternative drive mechanism replacing the small pinion gear 15 and large ring gear 9 utilized in the aforesaid gear driven machine. This belt drive configuration results in like rotation of the propeller 35 and cylindrical drum 4. 
     As the wind blows, the machine pivots itself into the wind with the aid of it&#39;s directional vane and pivotal mounting base assembly. The wind drives the propeller which then by means of gears or pulleys, rotates a cylindrical drum, the axis of which is horizontal, mounted atop a framework having an array of tuned chime tubes vertically suspended, top and bottom therein. 
     As the cylindrical drum rotates, small pegs protruding from it engage, and depress the top ends of lever hammers, mounted on a common rod, thereby, lifting the bottom end of said lever hammers. As said pegs pass in their rotation, said pegs release the lever hammers allowing them to fall, striking the correct chime tubes in the correct sequence, thereby, producing the desired musical tones. 
     The pegs are snapped into the cylindrical drum in a preset musical pattern that can easily be changed. Also, the cylindrical drum contains all of the necessary peg location holes needed to play the songs found in the accompanying song-book. 
     The song-book contains a variety of songs which are in the form of coordinate lists. Each coordinate list shows the necessary peg location coordinates needed to play a song. These coordinates correspond with longitudinal and transverse coordinate lines and legends found on the cylindrical drum. 
     The wind powered music machine can be placed almost anywhere outdoors where a little breeze can drive it, preferably on a post near a garden or on a porch or deck railing. 
     The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and, accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
