'AERioDARr No.' seneca.

To all whom it may concern:

Be-it knownthat I, CAEsAR R. BANNiHii, a citizen of the United States of America, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Aerodarts, of which the following is a specification.

The object of this invention is to provide a suitable mounting for blades around a hub oli' simple, durable and inexpensive construction whereby a wheel is formed which may be utilized either as a propeller acting'upon the air or as a windwheel which is rotated by the air. The Wheel has been devised with the former object especially in view, and is illustrated in a device which is particularly adapted as a game implement to be pro'ected through the air from one player to anot er or as a toy for individual amusement.

In the accompanging sheet of drawings which forms apart o this application, Figure 1 is a perspective oi' an aerodart constructed in accordance with my invention. Fi 2 is a plan view showing the hub and ouelade with its connecting spring wire and the spring wires for the 4other blades partly broken awa I hub on the e Il -III of Fig. 2.

A hub A, conveniently of wood, has a liat facefsurmounted byv a central knob K which is joined to the iat face of the hub by a' neck N. The Vsides s of the knob ta er, the greatest diameter adjoinin vthe nec There is a hole h through the axis of the hub and knob,

is formed. The sidesv of the loop are brought' A shaft S sn'uglygiits the central hole in the hub. A plura 'ty of spring Wires W W, one for each of the blades,l three being illus* trated, have each a shortbranch b at ri ht angles which enga les Y one of the sina ery ewires are interlocked, each engaging the angle of an adjoining wire, and the portion of each wire midway between its angle and thepoint of enga ement Awith the angle of the next wire under ies the knob and is thereby securely held.` i

In assemblin the wires are rst interlocked l and the branc es which are to engagclthe holes brought to ther roper spacing.,v Theyf' are then sprung over t e tapered si of the knob into lace. At the outer or prpjectiii end of eac of the wires an.l elongated loop nearly together so as to form two lunequal l Sl'iecicii'tion of Letters Patent; Application filed December 24, 1908'. .Serial No. 469,086.

end being the smaller. Blades P, consisting conveniently of circular disks, which may be of iiber, paper or other material combining the requisite lightness and strength are carried at the ends of-the wire loops. A button B, which may be a smaller disk of the same .materiaL is centrally attached to each blade by aneyelet e. A blade can be inserted or removed by bringing the button op osite the larger eye in the loop, where it Ican )e passed through with or without a slight springing of the wire. The loops are bent out of the plane 0E revolution so that the blades will be suitably inclined to engage the air and suse tain or propel the dart' upward and forward as it revolves. The spring wires by reason of their elastic character, and further by reason of their being curved as shown, serve to reduce the force of impact in case a blade should come in contact with any ob'ect in the course vof the flight ofthe dart, t ereby averting inpry both to the blade and the object with w lich it may. come in contact.

'.lhe aerodart when employed in a gaine is held by its shaft between the palm of the left hand and the fingers of the rigl'it han'd with the palms parallel. The shaft is inclined slightly forward from the vertical in the direction'inwhichthe dart is to be projected, andit -is given a quick rotary movement b sliding the right hand forward, the shaft ro ing between the palms. The aerodart first rises until the u ward propulsive force of the blades is re uced to the weight of the ac rodart and then it glides forward in the direction of inclination, the blades serving las gliding planes.- Gyroscopic action keeps' the aerodartat the same inclination throughout` its Hight. `The aerodart is passed from one pla er to another under rules, for example, suc as are observed in playing tennis, but on a'siiialler court. The game, however, is not restricted to this manner of playing.

What I claim as new, and desire tosecuie by Letterslatent ofthe United States, is-

Y liz'lhe combination `of a hub, a plurahty ably inc ed blades carried by the wires.,

2. The combination of a hub, a plurality of sprin wires attached to the hub, and suit,

3. The combination of a hub, a plurality l of spring wires attached to the hub with loops with a centrally disposed button Which is engaged by one of the spring wire loops;

4. The combination of a hub, a plurality of spring wires attached to the hub each of which has its projecting end folded over to form an elongated loo the sides of which are brought nearly togetlier so as to form two communicating unequal eyes the smaller of which is at the outer end'7 and a plurality of l blades each of which is provided with a cen trally disposed button which is engaged by the smaller eye of a loop.

' 5. The combination of a hub, a knob joined thereto by a neck, a plurality of interlocking spring wires in engagement with the neck between the interlocking points, and blades carried by the Wires.

6. The combination of a hub, a knob joined thereto by a neck, a` plurality of interlocking spring wires in engagement with the neck between the interlocking points, the ends of the Wiresadjoining the interlocking points being embedded in the hub, and blades carried by the wires.

The combination of a hub, a knob joined thereto by a neck,aplurality of inter* locking spring Wires in engagement with thi` neck between the interlocking points with loops formed on their rojectins,r ends, and a plurality of blades eac of which is rovided with a centrally disposed button which is engaged by one of' the spring wire loops.
