UNITED sTATEs PATENT orrion AIIBERT L. PLATT, OF CLINTON, ILLINOIS.

AERlAL. TOP- Specification of Letters Patent.

Patented Feb. 27,1905.

Application filed June 20, 1905. Serial No. 266,131;

To all whom it may concern."

'Be it-known that- I, ALBERT L. PLA'rr, a citizen of the United States of America, residing at Clinton, in the county of Dewitt and State of Illinois, have invented certain new and use- "embo yingmeans forv imparting a rapid spinning motion to the whirlingmember y a single spiral Wrap of thecord about the spinnin -'stem of said member. 3

V%'ith these and other objects in view, which will more readily appear as the nature I of the invention, is better understood, the

same consists in the novel construction,.com-

bination, and arrangement of parts, which will be hereinafter more fully illustrated, described, and claimed.

The essential feature of the invention involved in the manner of housin and guiding the operating-cord'is necessari y susceptible to some structural change withoutdeparting from the sec e of the invention; but a preferred embodiment thereof is shown in the accompanying drawings, in which Figure 1 1s a perspective view of a top em-" bodying the present invention, showing the whirling member carried by the su portinghandle 111 a osition to be'operat eci. Fig. 2 isv a longitudinal sectional view of the top, showing the arrangement of theoperatingcord for spinning and rojec'ting the whirling member. Fig. 3 is a etail view of the whirling member as it appears while in flight.

Like reference-numerals designate correplponding parts in the several figures of therawmgs.

' The toy in its general organization essentially comprises a sup orting member 1, a whirling member 2, an an operating-cord 3. The supporting memberof thetoy is preferably in'the' form of a tubular handle providing a holder which can be conveniently and readily grasped by one hand of the operator,

thus leaving the other hand free for manipulating the cord to provide for whirling and projecting the whirling member or top proper: he long tudinal-bore 4 of the said supporttially straight line.

ing handle extends throughout the entire length of the latter and constitutes a guiding means for the spinning-stem 5 of the whirlin member, 2, whereby the latter is pro'ecte fromc-the supporting handle in a su stan- The said whirling memher 2 essentially consists of the s inning-stem 5 and the screw-propeller bla e 6, secured fast upon one end of the stem and disposed at right angles to the axis thereof. "lhe pro peller-bladc 6 is formed with the opposite reversely-inclined Wings 7, which provide the conventional screw-propeller action when a whirling motion is imparted to the whirling member or top pro er and which action serves to maintain tie whirling member in flight as long as the speed of rotation is sufficient.

A distinctive feature of the'invention resides in the novel manner of housin and guid ing the operating-cord 3. This cord is threaded through a cord-holding guide-eye 8, piercing the wall of the tubular handle 1 near the upper end. of the latter, and'is designed to be drawn or pulled through a di'awing-kerf 9,

formed in the top edge of the handle in a hi her plane than the eye 8. The said kerf 9 IS Iormed with a downwardly-sloping base 10 to. form a guiding-surface over w oh the o crating-cord may be freely drawn,,and in t e interval between the guide-eye .8 and the kerf 9 the cord 3 is designed to be given a single s iral twist 3 about the stem 2 of the 'whir mg member. By reason of this single spiral twist of the operating-cord the latter may be quickly drawn-from the eye 8 throughthe kerf 9 to im parta rapid-spinning motion to the stem-2 and the propeller carried thereby, whileat the same time serving to mechanically lift the stem 5 out ofits guidingbore 4 and forcibly project the whirling memher or top proper into the air;

, Inoperating the toy it is simply necessary to drop the stem 5 in the sup orting-handle, place a single twist of the cor about the said stem, and drop the pull end thereof into the kerf 9. It isthen simply necessary to draw. out the cord rapidly through the kerf to secure the action referred to.

To provide proper and. free play for the spiralwrap of the operating-cord, the su porting-handle 1 is formed in its upper en with an enlarged housing-socket 11, which is an enlargement of the guidin -bore. w

I Having thus desc 'bed t e invention, what is claimed, and desired to be secured by Letters Patent, is

An aerial top, com rising a tubular supporting-handle provid ed near its upper end with a transversely-disposed cord-holding guide-eye, and in its top edge in a hi her plane than the eye with a downwardly-s 0ping drawing-kerf, said handle being also pro- Vided at its top edge with an enlarged housing-socket, a whirling member consistin of a spinning-stem lying within the bore 0? the supporting-handle, and a propeller-blade car ried by said stem, and an operating-cord assing through the guide-oye and drewinglierf and having its portion between these elements arranged about said stein in a single spiral wrap, the latter lieingg; arranged to operate in said h0using-socket.

In testimony whereof I aflix my signature in presence of two witnesses.
