duplication filed ym This invention relates to improvements in spinning tops, the general ohject ot the invention being to provide means wherehy the cord used with the top can he easily and quickly wound on the stem oi the top and operated to impart a rotary movement to the top, the operation and construction oi the device heing so simple that a small child can spin a top as easily as an older one.

llinother ohject ot' the invention is to so arrange the parts that the cord will exert the maximum amount of power on the stem of the top so that the top will spin with great rapidity and for a long time.

lihis invention also consists in certain other features o't construction and in the combination and arrangement oi the sev eral parts, to he hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

in descrihing the invention in detail, relierence will he had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side view showing the parts in assembled position with the string heing wound on the stem of the top.

Figure 93 is a similar view showingthe string fully wound on the stem and ready to he pulled therelrom.

Figure 3 is an end view of Figure 2.

Figure is a top plan view showing the parts in a position with the string ready to he attached to the stem.

Figure 5 is a sectional view showing the handle with the string in a position to re ceive the stem of the top.

its shown in these views, the top '1? has a notch 'l in the upper end of its stem 2, the loottom of the notch heing placed at an angle and having its upper end terminating in the top of the stem aojacent one side thereoft, with the lower end of the hottorn passing through a ot the tem a slight distunes from the top thereozh The handle is termed with a here 3 tier receiving the stem and with here 4iwhich is longitudinally arranged in the handle and has one end in communication with the here 8 and its other end passing through the end oil the handle. it vertically arranged slot 5 is formed in the handle he twecn the here 3 and the end oi? the handle,

this slot intersecting the bore l. A slot 6 is 'lorrned in one side of the handle and communicates with the bore 4 with its inner end arranged in alignment with the axis of the bore 3. This slot 6 is oi greater width than the slot 5 and a pin 7 passes through the slot 6 adjacent its inner end. The slot 5 is of such a width that the cord 0, used for imparting a rotary movement to the top, can readily pass through the same. A lrnot c is formed at one end of the cord and in using the device, the knotted end of the cord is placed on the upper face of the handle and the cord held in this position by the thumb of the hand holding the handle. The other hand then pulls the cord through the upper part of the slot 5 into the here at and then through the slot 6 so that the string will pass through the upper part of the bore 3, as shown in Figures 4 and 5. The stem or spindle 2 is then passed through the bore 3, with the notch 1 facin the slot 6. The cord is then released by the thumh and thecord pulled upon until the knot comes adjacent the end of the stem. Then the cord is placed in the notch l with the lrnot it at the top of the stem, as shown in Figures 1, 2 and 3, which will connect the cord with the stem. The handle is then turned edgeways with the slot 6 uppermost and then the top is turned to cause the cord to wind on the stem, as shown in Figures 1 and 2. A slight pressure may he placed on the cord by the thumb oi the hand grasping the handle and the stem should he pushed through the bore 3 as the top is being rotated so that the cord will he evenly wound in a spiral manner upon the stem. When a desired amount of the cord has been wound upon the stem, the parts are turned to their natural position and then the tree end of the cord is pulled upon, and this pulling action will cause the top to he rapidly rotated as the cord passes therefrom and at the same time the top will move downwardly and then as the top ol the stem passes through the horn. the cord will he released from the stem as the top thereof passes helow the plane of the slot 3. Thus the too is rapidly rotated so that it will spin with great rapidity and for a long time. lily forming the slot 5 as shown, the device can he readily used by either a right handed person or a left handed person, as either lllll face of the handle can be turned uppermost. The bore 4 not only facilitates the positioning of the cord, but it also enables light rays to enter the slot 6 so that the operator can observe the winding of the string on the stem.. The pin 7 acts to prevent wear on the cord and reduces friction to a minimum. As the pin is pulled upon with one hand, the other hand can move the handle in an opposite direction so as to increase the pulling orce.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is y In combination with a top having a stem with a notch in its upper end, a handle having a bore adjacent one end thereof for receiving the stem with a vertically arranged slot passing through the end of the handle and communicating with the bore, said handle having a second bore therein longitudinally arranged and having its inner end in communication with the first bore and its other end assing through the end of the handle with the slot bisecting said second bore, said handle having a transversel arranged slot therein which passes throug i one side of the handle with its inner portion in communication with the second bore and its inner end in communication with the first bore, a pin passing through the second slot and in alignment with the axis of the first bore, and a cord havin a knot at one end thereof with this end 0 the cord adapted to be placed in the notch in the stem and the cord passed through the top portion of the first mentioned slot into the side slot whereby the cord willbe wound upon the stem as the stem is rotated and moved through the bore, after which the opposite end of the cord is pulled upon to impart a rotary movement to the stem to force the stem from the bore in the handle. a

In testimony whereof I aflix my signature.
