ETHEL E. MILLER, OF CLEVELAND, OHIO.

AERIAL TOP.

Specification of Letters Patent.

Patented June 25, 1913.

Application filed September 21, 1917. Serial No. 192,585.

To all whom it may concern:

Be it known that I, ETHEL E. Minimal, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Aerial Tops; and I do hereby declare the followin to be a full, clear, and exact description 0 the invent1on, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to tops and is directed more particularly to what may be aptly termed an aerial top.

An object of the present inventlon resides in the provision of a top including a top and means cooperating in novel manner with the top to impart to thelatter a rotary impulse, said top being so constructed as to rise and sail through the air and remain suspended until its weight overcomes the resistance ofi'ered by the air, whereupon it will gradually fall, and, alighting upon the ground Wlll continue to spin until the rotary impulse ceases.

With the above and other objects of similar nature in View, the invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claim.

In the drawing,

Figure 1 is a side elevation of the invention, illustrating the position of the parts prior to rotating the top,

Fig. 2 is a vertical section therethrough, and

Fig. 3 is a perspective View of the top.

Referring now more particularly to the accompanying drawing, the invention comprises generally speaking a top A, and means designated at B for impartmg to the top a rotary impulse.

Specifically, the top A is preferably stamped from a single blank of sheet material and includes an annular rim 5, a central portion 6, and radially extending propeller blades 7 connecting sald rim and central portion. The central portion 6 of the top is depressed in any desired manner to provide a tapered socket 8 of substantially conical formation, the apex 9 of the cone constituting a suitable point upon which the top 5 is spun by manipulation of the spinner B above referred to. The blades 7 of the top are referably constructed as shown and are simi arly disposed at an lnclme like the blades of an ordinary propeller so that upon rotation of the top the blade will impinge on the air, thereby raising the top and causing the same to sail through the air. It is understood that the top will remain suspended until its weight overcomes the resistance offered by the air, whereupon it will gradually fall and, alighting upon the point 9, will continue to spin until the rotary impulse ceases.

Referring now to the spinner B through the medium of which a rotary impulse is imparted to the top, the same consists of a tubular handle 10 having mounted and suitably secured therein a coil of wire 10' providing a plurality of spiral convolutions as clearly shown in Fig. 2. Slidably mounted in the handle 10 is a plunger stem 11 provided adjacent its inner end with a lug or projection 12 engaging the convolutions of the wire whereby a thrust upon the handle, to move it longitudinally of the stem, will impart to the latter a rotary impulse. A cap 13 is provided to close the open end of the tube and prevent complete withdrawal of the stem therefrom. Fixed in any suitable manner upon the end of the stem is a circular disk 14 of fiber or other relatively hard, wear resisting material. The circular 4 disk 14 is beveled at its edge to frictionally wedge in the tapered socket 8 formed by the hollow in the central portion 6 of the top. It will be seenthat when the s inner is used and the disk 14 engaged in t e socket 8 a positive frictional engagement is had between the spinner and the top without regard to the perpendicular position of the spinner or the annular disposition thereof when the top and said spinner are in use.

In the operation of the device, to spin the top, the stem is withdrawn from the handle to its full extent and the latter grasped and held vertically with the disk 14 engaged in the socket 8 of the top. A rapid downward thrust is then given to the handle to rotate the stem, and the movement is imparted to the top through the medium of the disk 14:. The spinner B is then quickly removed from the top whereupon the same will rise and sail a considerable distance through the air, after which it will again fall as previously described.
