The handle is enlarged The upper end of the hub is formed to define a at its inner end to provide a body 2' which is cut point 20 which is adapted to impinge on the ceilv away to define a yoke 3 having spaced parallel ing of a room, or the like. As best seen in 'Fig- I arms 4 and 5. I ure 1, the lower end of the squared portion l9 of the stem to continue rotation after the propeller will ascend tothe ceiling. The propeller will spin upon the ceiling until some of its momentum is lost, when it will gradually descend and spin upon the floor until completely run down.

Momentum imparted by the flywheel will cause rises and the string will be partially wound in a reverse direction' upon the stem. Therefore, .when a quick pull is exerted upon the string the stem will be rotated in the original direction and the string will be first unwound and then partially or entirely rewound upon the stem. It will thus be seen that the flywheel ID will aid in re-' winding the spinning string I3 after a spinning operation, and that by the time the-stem stops rotating, the string will be completely-wound thereon and will be ready to be spun again.

.In view of the fact that I have'employed the flange I6 in conjunctionwith the propeller, said flange will prevent lateral shifting movement so that the propeller will be'permitted to ascend and descend substantially vertically. This flange will also prevent bending or breaking of the blades ll and-will tend toprevent damage to objects with whichthe toy may come in contact.

' Itshould be understood that, if desired,;th

top and flywheel may be removed from the yoke and the flywheel then again fitted upon the stem close to the disk and the device used as a yo-yo toy..-

it isbelieved that a reading of the foregoing description will render entirely apparent that I haveprovided a toywhich will be highly amusing.

and at the same time durable and cheap in manufacture.

Having thus described my invention, I claim: 1'. A convertible device of the character described, comprising a handle having a body formed witha yoke, a top having a stem rotatably engaged through the yoke, a disk carried by thestem below the yoke, a weighted fly wheel of appreciably greater diameter than the stem detachably carried by the stem above the yoke and projecting upwardly therefrom whereby the upper portion of the stem receiving bore of the fly wheel forms a socket, a propeller having a central shank detachably engaged in the socket of the fly wheel, and a string adapted to be wound upon the stem between arms of the yoke and V quickly unwound therefrom when pulled from its outer end for rotating the top whereby said propeller will be rapidly spun and projected upwardly from the socket of the fly wheel during the spinning operation.

. 2..A convertible device of the character described comprising a handle having a yoke at one end including upper and lower arms formed. with alined openings, a stem rotatably engaged through the openings inthe arms of said yoke and projecting. above and below the arms, a disk of appreciably greater diameter than'the stem rigidly carried by the stem'below the lower arm in spaced relation to the lower end of the stem, a weighted fly wheel detachably connected with the stem above the upper arm and-formed with a center opening open at its upper end, the stem being. releasably secured in the opening of the flywheel with its upper end'spaced from the upper end of the opening whereby the portion of the opening above the stem forms a socket open at its upper end, the said socket being non-circular in cross section, a propeller'having a hub formed at one end'with a spinning point and at its otherv end being reduced to form a shank loosely received in the socket of the fly wheel and conforming to the cross sectional shape thereof, said propeller having blades radiating from the'hub and a rim about the outer ends of the blades, and a string adapted to be wound about the stembetween the arms of the yoke and quickly unwoundfor rotating the top and propeller wherebydisengagement of .the propeller from the-fly wheel and ascension of the propeller will take place. a OLIVER H. BENNETT. [L. 5.]
