: I 1 Clairn. ,(Cl.27 3-, -132) f This invention relates to a game which might be: called a geometric progressive puzzle wherein the objectis to move a stack of discs from one post to another post, moving only one disc at a time, and without placing a larger disc on a smaller disc. Where ten discs are employed, there will be a minimum of. 1023 moves. 'The' invention involves a structure comprising a base largely hollow from the underside and triangular in shape as ,viewed fromthetop side; a post removably carried at eachcorner of the base to extend normally upward; a--plurality-of discs, ten being shown in the accompanying drawing and description; these discs being so shaped as to nest one with another to give a minimum height when stacked one over the other, and when reversed inposition one ,on top of*the other, togiv'e an increased height.- A purpose of-having an increased height from the minimum height of nesting is to permit easy handling and picking up of the individual discs from a stack. The minimum height is desired for storage purposes, since the', invention-involvedis inthe structure in the stacking of the individual discs in the reduced height condition within the base from .its; 'underside,.'and also the invention provides for the placing of. the pins 'in this space to be held therein under the stacked discs by any simple means, such vasv a.- pin. passing through the discs and engagingwiththe base. I Also there is the purpose involved in this invention of making the discs available for ready picking up by placing them initially on a post at the corner of the base whereby the discs overhang the base by major areas, at least of the larger diameter discs, no two discs being of ture which may be exceedingly simple in form, and

' which may be reduced from a playing condition to a storage or transporting 1 position to occupy the minimum amount of space.

These and many other objects and advantages of the invention will become apparent to those versed in the art in the following description of-one particular form of the invention as illustrated in the accompanying drawings, in which:

Fig. 1 is a view in top plan of a structure embodying the invention and set up for playing;

Fig. 2 is a view in side elevation and partial section;

Fig. 3 is a view in side elevation of a post;

Fig. 4 is a bottom plan view of the structure in a disassembled and nested condition;

Fig. 5 is a view on an enlarged scale in section on the line 5--5 in Fig. 4;

Fig. 6 is a view in side elevation of a securing pin;

Fig. 7 is a similar view of the pin revolved 90 from the position shown in Fig. 6; and

Fig. 8 is a view in bottom plan in reference to Figs. 6 and 7.

A base 10 is formed to be generally triangular in shape, Figs. 1 and 4, and is provided with three vertically disposed holes therethrough, these holes being indicated by the

numerals

11, 12 and 13. The top side 14 of the base 10 is' preferably planar in sha e, -and, for playing; 'the base 10 carries three posts15, 16, and 17." Each of these posts 15-17 is identical in shape, and size,

and is formed to havethefshapefasdndicated in Fig. '3, wherein there f is a cylindrical upper-portion 18 having preferably'a rounded upper end nose 19. j The lower end portion 20 has a diameter which will permit it to be received in] any c eer the base holes 12-13 witha rather free sliding fit. "-The penetration of the base end l0 discs as are shown in the present form'of the invention; The practical minimum amount of time to complete the game with 10 discs would be right around 20 minutes: The time required to complete the game 'is a decided measure of the-skill and-ability of the player. These discs are numbered from 23 through32. Each of these discs is shaped inthe same'manner} but varies one from the other by decreasing diameters ranging from the major'diamet'er'for disc 23 to the smallest diameter for disc 32. Furthermore, each of these discs is'shaped to have a central planar area 33 from the outer peripheryof which there is a downturned flange 34having an initial cylindrical surface 35 from the lower end of which there is a-frustd-conical surface 36. The inside diameter of one flange35 as' 'at'the surface 37 is madeto be such that the cylindrical surface of the flange of the next diameter disc will fit freely fingers by engagingI-thatinclined surface; Also it is to be: noted when the discs" 23- 32 are stacked in the arrangement shownjinFig. 2, a maximumove'rallheight is obtained, whereas when the discs are stacked asarrariged in Fig? 5, -a minimum overall heightisfob'tained; Also when the arrangement is had as shownin Figi 5; there is no tendency for the discs to slide laterally one over the other.

preferably reinforced by three ribs, 38, 39, and 40 radiating inwardly toward the center of the base from the corner portions of the base. Each of these ribs 3840 has an inner sloping surface 41 and the stack of discs 23-32 as nested in Fig. 5 may be received over these surfaces 41 and thus be centrally located from the underside of the housing pin, and the thicknesses of the discs are made to be such that the entire stack will be received within the vertical thickness of the base.

Centrally located within the underside of the base, Fig. 5, is a boss 42 which has that diameter to enter within the surrounding flange of the disc 32 so that the stack is thereby centered over this boss 42. There is a hole 43 entering from the top side 14 of the base 10 and extending through this boss 42. This hole 43 has a frusto-conical surface 44 tapering inwardly from the base 14 to a rather sharp shoulder 45, from which shoulder the hole tapers outwardly therefrom so that the shoulder 45 is well defined.

The

posts

15, 16, and 17 have overall lengths which will permit them to be placed in the cavity opening from the underside of the base'to have the posts lie between the

respective ribs

38 and 39; 39 and 40; and 40 and 38. The corner portions of the base 10 through which the holes 11-13 extend have inner faces 46 and 47 extending between the side walls 48 and 49, for example, to rib 40 Patented Mar. 20, 1956 The base 10 is hollowed out from its underside and in such shape to permit the posts 15-17 to he received therein with the maximum possible length of post.

Each of the discs 2332 has a central hole 50 therethrough, the hole being of the same diameter in each ofthediscs. V 1 i .A p n, s 6- e e ally designated y th numeral 1 h s a a h a 52 f om hich ext nd a cy indric l l g h 53 hi h is at d y m a f. the sl9t54 to define two

pin shoulders

61 and 62 to snap over on the surface 44 and h r by cause th P n 51 to be u e y t d n pos tion so that the discs are maintained within the base 10, an t e pi s or posts 1517 ar al o e ne y ex ding under the discs as indicated in Fi s. 4 and 5. The pin 51 may be readily disengaged from the shoulder 45 by pushing relatively downward from the surface 14 on the exposed

fingers

55 and 56.

To play the game, all of the discs 2 3--32 are superimposed one. upon the other, in the order indicated in Figs. 1 and 2 to have the post 15 to extend through the holes 50 of the discs. As will be noted, Fig. 1, the major portions of the stacks of discs extend outwardly from one corner of the base 10. Then the object of thegame is to transfer all of the discs from the one post 15 to either the

post

16 or 17. This operation may start as follows: Disc 32 to post 17; disc 31 to post 16; disc 32 to post 16; disc 30 to post 17; disc 32 to post 15; disc 31 to post 17; disc 32 to post 17; disc 29 to post 16; disc 32 to post 16; disc 31 to post 15; disc:32 to post 15; disc 30 to post 16; disc 32 to post 17; disc 31 to post 16; disc 32 to post 16; disc 28 to post 17; disc 32 to post 15; disc 31 to post 17; disc 32 to post 17; disc 30 to post 15; disc 32 to post 16; disc 31 to post 15; disc 32 to post 15; disc 29 to post 17; disc 32 to post 17; disc 31 to post 16; disc 32 to post 16; disc 30 to post 17; dis 2 o pos 15; i 1 to post .1 disc 32 to post 17; and disc 27 to post 16.

In like manner, the game may be continued and the moves made in accordance with the skill of the player to effect the eventual transfer of all of the discs in the order of arrangement as the discs are shown in Fig. 2. The sequence of moves may of course be varied, and the present invention is not dependent upon the exact sequence employed.

While I have herein shown and described my invention in the one particular form, it is obvious that structural changes may be employed without .departingifrom the spirit of the invention, and I therefore do not desire to be limited to that precise form beyond the limitations which may be imposed by the following claim.

I claim:

In a game structure, a triangular shaped base having an underside cavity defined by side walls extending downwardly from saidbase; a plurality of playingdiscsof uniformly varying diameters from a large to a small diameter disc stacked one upon the other in said cavity with the smallest diameter disc uppermost, each of said discs having a central hole therethrough; a web entering said cavity from each corner thereof, each of said webs tapering upwardly from a lower edge toward the center of thecavity by a slope parallel to the slope of the margins of said stacked discs; at post lying freely in said cavity along each of said walls and between adjacent webs; said stack of discs overlying said posts by largermost diameter discs; said base having a central hole therethrough; and a headed pin abutting by its head the largest diameter disc, extending upwardly through said stack, and detachably engaging a marginal portion of a'hole adjacentthe face of the base.
