AERONAUTIC TOY.

Patented Oct. 16, 1906.

-To all whom it may concern.-

Be it known that I, ELMER L. BRILLHART, a citizen of the United States, and a resident of the city of Ludin ton, in the county of Mason and State of 'chigan, have invented certain new and useful Improvements in Aeronautic Toys; and. I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawin s, and to the letters of reference marked t ereon, which form a part of this specification.

Thisinvention relates to improvements in aeronautic toys, and more particularly to a toy adapted to elevate and for a time support itself in the atmosphere.

The object of the invention is to afford a toy of cheap, simple, and durable construction and capable of elevatin itself to a considerable height and which aving attained its maximum height is adapted to be partly supported on the atmosphere to retard its descent.

It is also an object of the invention to afford a construction ada ted to be sold at a small price and to affor, in connection with a suitable arachute, a propelling mechanism capable o lifting itself against gravity.

The invention consists 1n the matters hereinafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is an enlarged side elevation of a device embodying my invention. Fig. 2 is an enlarged fragmentary detail of a part of the motor. Fig. 3 is an enlarged vertical section, partly broken, showing the parachute closed. Fig. 4 is a fragmentary top plan view of the same. Fig. 5 is a section taken on line 5 5 of Fig. 1. Fig. 6 is a view similar to Fig. 3, but showing a different support for the parachute.

As shown in said drawings, A indicates a shaft or standard, conveniently a light tube of thin metal, having secured at its upper end a fan comprising radial obliquely-set liftingblades B, as shown four in number, though obviously any desired number may be used, and by the revolution of which by said shaft A the device is lifted. Said shaft A extends rotatively through a casing C at the lower end thereof. Said casing, as shown, is formed of metal stamped to afford a spider or cage which supports the motor. Said motor, as shown, comprises a coiled spring 0, positively secured upon a clutch member 0 at its inner end and at its outer end secured on the arm 0 of the casing. Extending through said clutch member 0 and thespring and through and rotatably engaged with the bottom of the casing is a WlIldlIlgStIld or shaft 0 The winding stud or shaft 1: is rigidly secured in said clutch member 0 and extends through a gear a on the inner side of the casing and on the end of which, extending through the casing, is a clutch member 0 complemental with the clutch member 0' and adapted to rotate said gear on the windingshaft by the action of sald spring. Said gear a intermeshes with a pipion 0, journaled upon a shaft a", secured in the casing, and is integrally connected with a gear 0 on the same shaft. Said ear 0 intermeshes with a pinion c", journale in the top of the casing integral with a gear 0 which in turn intermeshes with a gear a, secured on the inner end of the shaft A. v Said motor rotates the shaft at a high rate ofspeed relatively to the rotation ofthe gear 0. Secured axially of and in the to of said shaft A is a spindle a of much smal er size, having secured thereon at its top a parachute of any suitable light fabric or material a, which may be of any desired size or shape. Said parachute, as shown, is connected at intervals around its margin, by means of cords ahwith a ring or collar a secured on said spindle and which acts to limit the upward and outward movement of the margins of the parachute when the weight of the device is supported inthe atmosphere.

The operation is as follows: Having wound up the motor, producing a maximum tension upon the spring, the device is supported loosely upon the hand or upon any suitable su port, and the motor acts to rapidly revo ve the shaft A, whereby the fan B acts to elevate the device to any height, dependent upon the strength of the spring, the speed of rotation, and weight of the device. It is obvious that the parachute remains folded together, as shown in Figs. 3 and 4, with the spindle revolving therein, and presents practically no resistance in the atmosphere during the upward movement. When the motor has nearly expended its energy and the device begins slowly to sink, the upward pressure beneath the parachute spreads the same, as shown in Fig. 1, while the remaining energy of the motor aids in supporting the same, prolonging the. flight of the device. Ordinarily the motor is constructed, as shown, with radial arms C extending beyond themotor-frame, the plane of which extendsparallel with the axiaofithe shaft and which;

though very light, acts to revent rotation of the motor. As shown in g. 5, a skeleton or;

frame D is supported at the up r end of the shaft A, uponwhich the parac ute is folded inwardl the cords thereof attached to upwardly-directed arms a. e arachute in this construction operatosas efore described, a slightly-descending movement acting to sprea the parachute by the upward pressure of air from beneath the same and through the skeleton frame.

While I have shown but one construction for this invention I do' not purlpose limiting this application for patent ot erwise than necessitated by the prior art, as many details of construction andoperation may be varied without departing from the principle of my invention, and obviously any desired material and proportions of partsmay be used, as desired. 4

I claim as my invention- 1. An aeronautic device comprising a,mo-'

tor, a vertical shaft driven thereby, inclined radial fans thereon set to lift the device when theshaft is rotated and a arachute journaled in the to of said shai t and normally folded during t e ascent.

lnble shaft, a fan rigidly secured at eaauo4 2. aeronautic device embracing a revo lu-ble shaft, a, fan rigidly secured thereon comprising radial blades or arms set obliquelyzto raise the device, means rotating the shaft, a non-rotatable spindle extending from the to of said shaft and a parachute supported tl iereon and closed during ascent. 3. An aeronautic device embracing a revot e upper end thereof compnsing radial arms, set obliquely to lift the device, a s ind le supported rotatably on the up er on of, and m axial alinement with the s aft, a parachute carried on said spindle, a motor for driving said shaft and radial ribs or vanes on the motor-case holding the same from rotation.

4. In an aeronautic' device, a casing, a revoluble shaft therein, a spring carried in said casing, a clutch connectin said shaft, a parachute an a frame on the endof said shaft afiording a support for the parachute.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
