J. C. STIMSON Aug. 3, 1965 WEIGHTED DICE Filed Dec. 19, 1962 INVENTOR.

JONATHAN C. STIMSON ATTOR NEY United States Patent 3,198,523 WEIGHTED Dl CE Jonathan C. Stimson, Arlington, Va. (M94 Lincoln St, Evanston, Ell.) Filed Dec. 19, 1962, Ser. No. 245,920 3 Claims. (Cl. 273-146) This invention relates to dice designed for use in a game pertaining to the stock market.

The particular game for which the dice are designed comprises a circular board divided into sectors corresponding to different stocks and to operations or plays which the players must perform as an incidence of stock ownership. Mounted on the board is a rotatable spinner or pointer which is spun by each player during the course of play and when the pointer lands or comes to rest on a sector corresponding to a particular stock, the player has the option of buying any unsold shares or selling shares which he already owns. The buying and selling prices are determined by the throw of dice.

The game includes a set of dice grouped or divided into playing dice and reserve dice. When a player buys or sells stock, he throws the playing dice and the transaction price on a per share basis is determined preferably by the sum of the numbers indicated by the thrown dice.

Each of the dice is numbered and if the dice are thrown and they indicate a predetermined sum such as seven or element, a market change occurs and the player who has just thrown the dice must substitute any number of reserve dice for an equal number of playing dice and thereby maintain the same number of playing device.

The dice are loaded or weighted so that, when thrown, some usually indicate or come up a low number and some usually indicate a high number. Thus, when a market change occurs, a player can shift the market, dependent upon which dice are reserve dice, to create more favorable conditions for himself as by switching the dice to present a low or buyers market, a high or sellers market, 'or a mixed market.

Accordingly, the primary object of the invention is to provide a set of dice for use in a game of the abovedescribed character.

Other objects and advantages will be apparent from the following description taken in connection with the accompanying drawing wherein:

FIG. 1 is a perspective view of a set of dice embodying the invention;

FIG. 2 is an enlarged perspectiview view of one of the dice shown in FIG. 1; and

FIG. 3 is a longitudinal sectional view along lines 3-3 of FIG. 2.

Referring now to the drawing, there is shown in FIG. 1 a set of dice comprising four dice divided, grouped and paired into playing dice and 11 and reserve dice 12 and 13. Each of the dice is in the form of an octahedron having eight, flat, similarly-shaped, triangular faces. The faces are preferably in the form of equilateral triangles although isoceles triangles can also be used. The particular shape of each face is relatively unimportant so long as each has the same tendency because of its geometry to come to rest upon the surface on which the dice are thrown and this can be most economically accomplished by using the aforementioned triangular shapes.

With reference to FIGS. 2 and 3, each die comprises two hollow halves 14 and 15 having a partition 16 between them which encloses in one of the halves a Weighting ball 17 of a heavy material such as lead. The halves can be 3,198,523 Patented Aug. 3, 1965 'ice molded or formed of separate panels and adhesively joined together.

The ball weights one half so that, When the die is thrown a face of the weighted half tends to come to rest upon the playing surface more often than a face of the other half, this being an equal change for each face of the Weighted half to do so. Obviously then, when such a die is thrown, the numbers on the other or unweighted half come up more often.

Each of the dice is numbered as by applying a numeral, painted clots or, as illustrated, recesses 21 to the faces. Preferably, the faces are numbered one through eight. One half is numbered with the four lower numbers and the other half is numbered with the four higher numbers. In the set of dice, some (dice 1i) and 12) are weighted so that the low numbers tend to come up and the others (dice 11 and 13) are weighted so that the high numbers tend to come up.

As previously indicated, the dice are used for determining per share stock prices in buying and selling transactions where the price is determined by throwing the playing dice and adding the numbers that come up in the dice. Should a certain number or numbers, e.g. seven or eleven, come up, the player who threw the dice must exchange one or both of the playing dice for the same number of reserve dice to change the market.

While only a single embodiment has been described, it will be apparent to those skilled in the art that changes can be made in the details and arrangement of parts without departing from the scope of the invention as defined in the appended claims.

What is claimed is:

1. A set of dice comprising: a plurality of dice divided into playing dice and reserve dice; each of said dice being a polyhedron having two halves bounded by fiat, similarlyshaped faces numbered so that one-half has numbers different from those numbers on the other half and each face on a half is numbered differently from the other faces on that half; and means weighting each die so that one half tends to come up more often than the other half and the faces of said one-half each have an equal chance of coming up.

2. A set of dice in accordance with claim 1 wherein the halves of each die are numbered so one-half has numbers lower than the other half.

3. A set of dice in accordance with claim 1 wherein the weighted half of each die is hollow and said means Weighting comprises a freely-movable weighting ball enclosed by said weighted half of said die.
