JAMES R. PEARSALL AND ALBERT D. HILL, OF ROCHESTER, NEW YORK, ASSIGNORS OF ONE-THIRD TO ROBERT WADSWORTH, OF ROCHESTER, NEW YORK.

To all whom it may concern."

Be it known that we, JAMES R. PEARsALL and ALBERT D. HILL, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Spinning-Tops, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to spinning tops of the type in which a spring on the top is employed for giving momentum thereto, and an object of the invention is to provide a construction in which the spring is so connected that it cannot be broken or otherwise put out of order by winding the same in the wrong direction.

Another object of the invention is to provide a simple release for said spring conveniently mounted for manipulation by the user supporting the top, thus permitting the top to be operated by one hand.

To these and other ends, the invention consists in certain parts and combinations of parts all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 shows the top in side elevation with a portion of its body in section; Fig. 2 is a vertical axial section; Fig. 3 is a top view of the spring container removed, the spindle being shown in horizontal section; Fig. 4 is a section on a line b-? Fig. 1; Fig. 5 is a top View of the device; and Fig. 6 is a detail view of the clutch I'lIl 1T1 carrying out the invention, there is employed a spindle 1 having its lower end provided with a spinning point 2 and its upper end provided with a hand piece or cap 3 the spindle being reduced, passed through an opening in the cap and upset thereon.

Mounted to turn on the spindle is a body comprising preferably a sheet metal web 5 reinforced at its edges by a weighted ring 6. At its center the web 5 has a perforated boss 7 struck up therefrom and surrounding the spindle 1, said spindle having, in this instance, an annular rib 8 engaged by the under side of the Web to support the body.

For the purpose of holding the body against rotation on the spindle, the latter may carry a clutch member preferably in Specification of Letters Patent.

Serial No. 639,708.

the form of a sleeve 9 surrounding the spindle above the body and having its lower end provided with a clutch face 10 to cooperate with a clutch face 11 on the boss 7. The sleeve 9 may be held against rotation on the spindle 1 by means of a disk 12 rigidly secured to and forming a flange or finger piece at the upper end of the sleeve, said disk having a noncircular opening which fits the noncircular upper end of the spindle 1, the latter, in this instance, being flattened at 18 to engage a flat face 14: on the disk 12. Normally the clutch member 9 is pressed toward the clutch member 7 on the body by means of a coil spring 15 surrounding the spindle 1 between the disk 12 and the cap 3.

Connected to the spindle 1 and the body of the top is a coil spring 16 preferably of volute form. In this instance, this spring is contained within a housing 17 struck up from sheet metal into cup form and having fins 18 at its upper edge passed through and upset upon the web 5, thus forming part of the body of the top. Of course, the bottom of this housing should have a central opening for the passage of the spindle 1, so that the lower end of the spindle projects below the bottom of the housing. The outer end of the spring 16 is bent into a loop 19 so as to be passed about a projection 20 formed by slittingthe side walls of the cup at 21, the walls of said slits being deflected as shown in Fig. 3 to prevent the formation of sharp corners. Between the spindle l and the other end of the spring 16 a clutch connection is provided which permits the body of the top to rotate on the spindle in one direction without affecting the spring, while, in the other direction, driving connection between the spring and the spindle is established causing the spring to be wound. In this instance, the clutch is in the form of a ring 22 surrounding the spindle 1 within the container 17, said ring having an internal shoulder 23 which cooperates with the shoulder 24 on the spindle 1, upon the turning of the body in one direction, but rides freely over said spindle and its shoulder upon the turning of the top body in the other direction, this being due to the fact that the opening in the ring is much larger than the diameter of the spindle and its shoulder. The connection between the clutch ring and the spring 16 may be formed .winding in the wrong direction.

by rolling the inner end of the spring at 25 to fit within a notch 26 in the periphery of the ring.

In the operation of the invention, the cap 3 is engaged by the fingers of one hand while the ring 6 is engaged by the fingers of the other hand to produce a relative rotation be tween the top body and the spindle 1, thus winding or tightening the spring 16. During this relative rotation, the clutch member 9 yields on the spindle 1 and finally holds the parts in their adjusted positions. The top is now placed with its point 2 against the surface upon which it is to spin. The

thumb of one hand is placed upon the cap 3 and the forefinger and middle finger of the same hand are positioned beneath the flange 12 on opposite sides of the sleeve 9 which is now elevated by said fingers, thus freeing the body and permitting it to turn on the spindle 1 under the action of the coil spring 16. Immediately the body begins to turn on the spindle, the top is released and the clutch sleeve 9 under the action of spring 15 enters into engagement with the top body, thus again establishing a connection between .Said body and the spindle, so that the top turns on the point 2 under the momentum produced in the top body by the spring 16. It will be noted that the tendency of the ,volute coil, due to the fact that its inner end is secured to the ring 22 substantially dia- -me'trically opposite to the shoulder 23, is to hold the shoulder 23 in position to be engaged by the shoulder 24: on the spindle, or in other words that side of the ring containing the shoulder 23 is held against the spindle 1.

From the foregoing, it will be seen that there has been provided a spinning top of the type having its own spring in which all parts thereof are carried to the top. The top is adapted to be released by one hand of the user and its spring is so connected that it cannot be broken or distorted through Furthermore, should the user fail to release the sleeve 9 before the spring is unwound, there will be no reaction in the top as the body will turn on the spindle.

What we claim and desire to secure by a body rotatable thereon, a spring secured at one end to the body, and a clutch connection between the spring and the spindle adapted to permit the body to rotate freely on the spindle in one direction.

3. A spinning top comprising a spindle, a body rotatable thereon, a coil spring surrounding the spindle, and having one end secured to the body, and a clutch connection between the spindle and the other end of the spring adapted to permit the body to rotate freely on the spindle in one direction.

fl. A spinning top comprising a spindle, a body rotatable thereon, a coil spring surrounding the spindle, and having one end secured to the body, and a clutch ring loosely surrounding the spindle and adapted to engage therewith and to permit the body to rotate freely on the spindle in one direction.
