This invention is a novel andA unique puzzle consisting of'. a block having. a. pairofbpposi-tely extending tortuous grooves thereinjprpviddiwith;

sets of parallel., races extending from, the center to the, olggpos'it'eY ends thero l p air of? balls are movable respectively, saidgrov`esr having bottom walls sloping upwardly from their starting or inner ends to their"A outer endslwhere the bottom walls terminate insubstantially horizontal'pla'tfo'rms, the solution ofthe puzzleconsisting in 4rotating or spinningl the'block withthe balls initially dispo s e d` at the inner ends of their respective tortuous grooves in such mannewr,- as.k ardsthe 01.1.1??? ends' to cause the balls to move' A n y t of their respective tortuous'grooves coming v`'to rest upon the horizontal platforms at the outer ends of the respective grooves.

I will explain the invention with reference to the accompanying drawing which illustrates one principal embodiment thereof, to enable others to adopt and use the same; and will summarize in the claims, the novel features of construction, and the novel combinations of parts, for which protection is desired.

In said drawing:

Fig. 1 is a top plan view of my novel puzzle showing the arrangement of tortuous grooves, and showing in full lines the balls at the outer ends of said grooves, and showing in dotted lines the starting positions of said balls in their respective grooves.

Fig. 2 is an end view of the puzzle shown in Fig. 1.

Fig. 3 is a longitudinal section through the puzzle, on the line 3 3, Fig. 1.

Fig. 4 is a longitudinal section on the line 4 4,

Fig. 1.

Fig. 5 is a transverse section on the line 5 5, Fig. 1.

Fig. 6 is a transverse section on the line 6 6, Fig. 1.

Figs. 7, 8 and 9 are plan, end, and edge views, respectively, of the transparent cover plate.

As shown in Fig. 1, the puzzle preferably comprises a block I of rectangular shape, having a recess Ia in its top face adapted to receive a transparent panel 3, shown in Figs. 7, 8 and 9. Below the panel 3 Within the base I are a pair of separate oppositely extending

tortuous grooves

2 and 4, each extending approximately one half the length of the base I, said passages being provided with a set of parallel

inner runs

2a and 4a disposed in parallel relation but at an angle to the longitudinal axis of the block, said channels having starting points 2b and 4b, respectively, at

Chaehls' are ebritinu'ouslyinclined upwardly from th inner 'starting points 2b, 4b to the outer terminal points 2e, 4e at which points the bases are iiattened as at 2f, 4f (Fig. 4) for the purpose hereinafter described.

Preferably the widths of the runs at the starting points 2b, 4b are enlarged as at 2g, 4g (Fig. l) while the outer walls of the

runs

2c, 4c at their entrances are recessed as at 2h, 4h, (Fig. 1) and the outer walls of the

runs

2d, 4d, at their entrances thereto are recessed as at 2k, 4k, for the purpose hereinafter described.

Within each pair of

grooves

2 and 4 is a ball 5 adapted to normally come to rest at the inner ends of the related

tortuous grooves

2 and 4 in the positions shown in dotted lines in Fig. 1.

The solution of the puzzle is to rotate or spin the block I so as to bring both balls 5 into the full line positions shown in Fig. 1, i. e., at the outer terminals 2e, 4e of the third set of

channels

2d, 4d. In order that the block may rotate freely, the same is preferably bevelled longitudinally and transversely on its bottom so as to provide a centrally disposed low point In: upon which the block may be spun, utilizing point I as a pivot. Starting with both balls 5 in the position shown in dotted lines in Fig. 1, the block is placed upon a hard surface and is rst spun in a counter-clockwise direction to bring both balls 5 opposite the entrances to the second set of

runs

2c, 4c, in which position they would be retained by the

recesses

2h, 4h in the outer walls of the said

runs

2c, 4c. By then spinning the block I quickly in a clockwise direction, the balls 5 would then be shifted or moved into positions opposite the entrances to the third set of runs 2d7 4d, in which position the balls would be retained in the recesses 27C, 4k: in the outer Walls of

runs

2d, 4d. By then again spinning the block I quickly in a counter-clockwise position, the balls 5 Would be shifted or moved to come to rest upon the terminal points 2e, 4e at the outer ends of the third set of

runs

2d, 4d, in which position the balls would remain seated upon said

flattened portions

2f, 4f preventing same from gravitating down the inclined bottoms of the tortuous passages to their initial starting points 2b, 4b. The block l may be made of any desired material and the transparent cover may be of glass, mica, celluloid or any transparent substance I do not limit my invention to the exact form sho-wn in the drawings, for obviously changes may be made therein within the scope of the claims.

I claim: A

1. A puzzle of the character specified, compris' ing a block having a pair of oppositely disposed toi'tuous grooves therein extending from the center towards the opposite ends thereof; the bottoms of the grooves inclining generally upwardly i from their inner ends to their outer ends and terminating in ball seats; the bottom of the block having a low central pivot point; the lower ends of the inner` runs being enlarged; and the outer Walls of the remaining runs being recessed at the entrances thereto.

2. A puzzle of the character specified, comprising a block having a pair of oppositely disposed tortuous grooves extending from the center toward the opposite ends thereof, said grooves being provided with sets of parallel runs disposed at diierent angles to the longitudinal axis of the block; the bottoms of the grooves inclining generally upwardly from their inner ends to their outer ends and terminating in ball seats; the bottom of the block having a low central pivot point;

the lower ends of the inner runs being enlarged; and the outer walls of the remaining runs being recessed at the entrances thereto.

3. A puzzle of the character specified, comprising a block having a pair of oppositely disposed tortuous grooves extending from the center towards the opposite ends thereof, said grooves being provided with sets of parallel runs, the adjacent runs of each groove being inclined in opposite directions with respect to the longitudinal axis of the block; the bottoms of the grooves inclining generally upwardly from their inner ends to their outer ends and terminating in ball seats; the bottom of the block having a low central pivot point; the lower ends of the inner runs being enlarged; and the outer walls of the remaining runs being recessed at the entrances thereto.
