AUGUST E. SANDSTROM, OF NEW YORK, N. Y.

SPINNING TOP.

1 43,2@ Specification of Letters Patent. Patggmtgd Jan 1Q), jggg Application filed November 29, 1920. serial No. 426,901.

To all whom it may concern Be it known that 1, AUGUST E. SANosTRoM, a subject of the King of Sweden, havlng declared my intentions of becoming a citlzen of the United States, and a resident of the borough and county of Bronx, city and State of New York, have invented certain new and useful Improvements in Spinning Tops, of which the following is a specificatiom My improvements relate to toy spinnlng tops, and my object is the productlon of a novelty in toys of this class which may be designated as a convertible twin top,-the halves of which may be used and spun separately, or combined into a duplex reverslble top at the pleasure, and in accordance w th the desire of the user,the invention consisting in th construction, combination and arrangement of parts described and claimed specifically, and a distinctive feature being the duplication of parts and coupling means whereby new results are attained, substantially as hereinafter fully set forth.

In the accompanying drawings,

Fig. 1, is an edge elevation of the twln sections of my device combined in the form of a reversible top;

Fig. 2, is an elevation of either face thereof;

Fig. 3, is a substantially central vertical section of the arrangement shown in Fig. 1;

Figs. 4 and 5, are elevations of the contactual faces of the twin sections shown in the preceding figures;

Figs. 6 and 7, are edge elevations thereof;

Fig. 8, is a View similar to Fig. 3, showing a modification;

Figs. 9 and 10, are edg elevations of the parts shown in Fig. 8;

Fig. 11, is a view illustrating the use of a spinning device in connection with my top;

Fig. 12, is a sectional view showing a modification in the coupling means.

My twin top consists essentially of duplicate sections, (Z, (Z, the contactual sides or faces 0, 0, of which are formed with interlocking copulative means, whereby the two parts may be conveniently and expeditiously united to form a unitary reversible top, as shown in Figs. 1, 2, 3 and 8, or separated for independent use as in the other figures of the drawings.

The duplicate sections (Z, d, are preferably of disc form, or substantially so, with fiat, or approximately fiat, contactual surfaces 0, 0,- the other, or what may be designated as the exterior surfaces 6, e, of the discs 0?, d, being made convex as shown, or otherwise shaped as may be found desirable or expedient for commercial reasons.

On the exterior sides 6, 6, so called, of the discs 03, (Z, are the spinning pegs p, p, preferably mounted on posts or stems s, 8, formed with cam shoulders s, s, for engagement with a spinning device, such for instance as that described and shown in my concurrent application Serial No. 380,968, filed May 13, 1920, and shown in part in Fig. 11, although other means of imparting a whirling motion to my reversible top, or

duplicate twin tops, may be employed without departing from the spirit and intent of my invention in this respect.

For a like reason I do not limit myself to the identical form and construction of copulative means shown, although preferable on account of cheapness and simplicity, and consisting of dowels a, a, on one section (2, fitting in corresponding sockets Z), I), in the other section d. A dowel a, and a socket b, may be provided on and in each section cl, d,

as shown in Figs. 3, 4., 5, 6 and 7 or both dowels a, w,may be on one section and both sockets Z2, 6, in the other section, as in Figs. 8, 9 and 10; or, obviously if desired, any plural number of dowels a, a, and sockets b, b, may be provided with like result.

In fact, if desired, the use of a single centrally positioned dowel a, and socket I), might be resorted to to effect the copulation of the sections cl, 0?, and would obviously be within the scope and intent of my invention, as indicated in Fig. 12.

My new convertible top is an interesting and instructive device for children, the detachable twin sections affording opportunity for change and experimental investigation. Thus, when the twin sections are united the reversible top thus created will spin true or perpendicular on its axis; whereas if the sections are spun separately, and the dowels are eccentrically positioned as inthe first seven figures of the drawings, the tops will wobble or spin eccentrically. Furthermore there is consisting of two separable duplicate sections provided with copulative means; consisting of dowels on one section fitting in corresponding sockets in the other section, 0

for the purpos described.
