The present invention relates to improvements in twin tops and. has for an object certain improvements on U. S. Patent No. 1,985,657 granted December 25, 1934, to Franklin J. Gustine and entitled Spring Operated Mechanical Toy.

Another object of the present invention is to provide an improved toy of this character in which a housing is provided for supporting and embracing the operating spring.

A further object of the present invention is to provide an improved structure in which the spindle of the lower top is resiliently supported by the operating spring which is placed under torsional tension only by the winding operation so that less force is required to break the interlock between the two tops at the time of launching or dropping the tops to effect the individual spinning thereof.

A still further object of the present invention is the provision of twin tops which comprise relatively few parts, are economical to manufacture and are sturdy so that they will stand the rough usage to which they will be put.

With the foregoing and other objects in view, the invention will be hereinafter more fully described and more particularly pointed out in the appended claims.

In the drawings, in which the same parts are denoted by the same reference numerals throughout the several views,

Figure 6 is a sectional inew taken on the line 6-6 of Figure 5 and looking in the direction of the arrows, and

Figure 7 is a sectional view taken on the line '!-1 of Figure 4 and looking in the direction of the arrows.

Referring more particularly to the drawings, the improved toy comprises twin tops generally designated as an upper top I0 and a lower top H. The upper top It) comprises a pair of dish shaped or concavo-convex sections 12 and I3 which are joined together at their marginal edges by an overturned seam M to provide a hollow body and a spindle [5 extending through aligned substantially centrally positioned openings in the sections l2 and i3. The spindle is fixedly secured to the sections [2 and I3 in any suitable manner and projects above and below the sections and its lower end portion has a tapered blunt end [6 upon which the upper top [0 is adapted to spin when deposited or launched upon a flat surface. The spindle I5 is provided in spaced relation to its lower end [6 with a laterally or radially extending pin H to provide a winding key and a locking pawl for cooperation with the lower top as later described.

The lower top H comprises an upper section It and a lower section [9 which are similar in shape and construction to the upper top sections l2 and I3, respectively, and provide a hollow body. The sections l8 and I9 have marginal edge flanges 20 and 2|, respectively, between which are positioned the peripheral edge portion of a septum 22 which is positioned within the hollow body formed by the sections l8 and I9. The sections l8 and I9 and the septum 22 are held in assembled relation by a flange which has a vertical portion 23 extending downwardly from the flange 29 of the section I8 across the edges of the septum and the flange 2| of the section l9 and a horizontal portion 24 firmly engaging the under face of the flange 2!.

The septum 22 has an enlarged substantially centrally disposed opening 25 therein and depending from the wall of the opening 25 is a skirt or flange 26 the lower edge of which rests upon the inner face of the section l9 and in cooperation therewith forms a housing and a support for a volute spring 21. The outer end portion of the spring 2'! extends through a slit 28 formed in the skirt 26 and is bent upon itself to form a hook 29 which faces in the direction of the movement of the spring during the winding or coiling operation.

The hook 29 receives the opposed adjacent wall 30 of the slit 28 and the other wall of the slit 25 is bent inwardly as at 3| and due to its inherent resiliency the bent portion 3! will tend to return to its original position and will frictionally engage the spring 2'! adjacent the hook 29 to urge the closed portion of the hook towards the wall 30.

The inner end portion of the spring 27 extends through a slot 32 formed in a hollow spindle 33 at substantially the longitudinal center thereof. The spindle extends through aligned substantially centrally disposed openings in the sections 18 and I9 of the lower top H and through the opening 25 of the septum and the innermost convolution of the spring 21. The inner end portion of the spring which is disposed within the hollow spin- 5 dle 33 is bent as at 34 to prevent the escape of the inner end portion of .the spring from the spindle.

The spindle 33 extends above and below the sections l8 and I9 'and'hasa tapered-:blunt'closed 10 lower end 35 upon which the lower top may spin and its upper end is open as indicated at 36 and has a shoulder 31 formed by a cam surface 387.- in the upper edge of the spindle 33. Aratchet or locking sleeve 39 is fixed in any suitable'man= 5 ner in the opening in the upper section l8:,of ;the lower top H and encircles the upper portion of the spindle to provide a bearin'g'for theupper end of the spindle. The upper end portionlofthe sleeve 39 projects above the action l8 and 5 the upper edge oithesleeve has a pair of diametrically disposed shoulders and l fll'which' are formed by the cam .surfacesr42lon. the upper edge of the sleeves. Thelshoulders llllandif face in a direction opposite to that 'in which the shoulder 31- of the spindle -33 faces, that the shoulders to and 4 I. face .acldckwise direction and the shoulder v31 faces-in ancounterclockwise direction.

At the same time the upper .top isv depressed toward the lower top soas to bring the pin ll in front of one of the shoulders.

During this action the shoulder 31 of the spindle 33 is maintained for a sufficient period of time in pressing contact with the pin I! so as to rapidly turn the upper spindle [5 with the upper top [0 in a direction opposite to the turning of the spindle 33 and the lower top I l.

The result of this operation is that the tops are turned or spun in opposite directions and the upper top is ejected with sufficient force tothrow it to one side of the lower top:so;thatthe two tops are left spinning independently upon the floor.
