fr @40M United States Patent O 3,092,389 GAME DISC Joseph W. Smith, 1309 Pritchard Ave., Winnipeg 4, Manitoba, Canada Filed Oct. 7, 1960, Ser. No. 61,223 1 Claim. (Cl. 273-123) My invention relates to new and useful improvements in games, more specifically, games which utilize a plurality of discs adapted to be hand propelled over a surface such .as lawn and the like.

It will be appreciated that the conventional game of lawn bowling requires a specially prepared surface relatively iiat and free from contour irregularities. Such surfaces are extremely expensive and difiicult to prepare and maintain and furthermore the bowls themselves are relatively expensive to produce.

My game is an adaptation of bowling particularly suitable for use in back gardens where the lawn may be relatively uneven.

The principal object and essence of my invention is therefore to provide a disc like structure which can be hand propelled over a conventional lawn and yet still retain the desirable characteristics of lawn bowling.

Another object of my invention is to provide a device of the character herewithin described which is relatively inexpensive to manufacture.

With the foregoing objects in View, and such other objects and advantages as will become apparent to -those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

FIGURE 1 is a top plan view of one of my game discs. FIGURE 2 is a transverse section of FIGURE 1. FIGURE 3 is a perspective view of one of my game discs.

In the drawings like characters of reference indicate corresponding parts in the different figures.

Proceeding therefore to describe my invention in detail, the discs 1 are preferably turned from a relatively hard wood but may, of course, be moulded from plastic if desired.

The base surface 2 is planar and what I dene as the upper surface 3 is dished or concaved as clearly shown in FIGURE 2.

It is desirable to leave a projecting shoulder 4 centrally located within the dished surface 3 to facilitate the picking up of the disc from the ground.

The perirnetrical rim 5 of the disc is desirably formed convex as clearly illustrated in FIGURE 2 as this facilitates the curving action of the disc in use, as will hereinafter be described.

`Concentrically inset within the base 2 is a weight 6 preferably formed of lead or similar material and it is this weight which causes the disc to curve in use.

In operation, the disc is propelled over the surface of the lawn or the like by the player, so that it rolls upon the perimetrical rim 5. The weight 6 causes the disc to curve to the left or to the right depending upon which side the weight is positioned during use. In other words, if the disc shown in FIGURE Z is rolled in the direction of arrow 7, then the disc will curve downwardly with respect to the drawings. If however, the disc is turned over so that the weight 6 is towards the upper edge of the sheet of drawings, then the disc will curve towards the upper side of the drawings.

The convex perimetrical rim facilitates this curving action and also permits relative accuracy to be obtained even on relatively rough surfaces and prevents this disc from toppling until nearly all of its rolling portion is spent.

The olf center action of the weight is, of course, assisted by the dished upper surface 3 of the disc so that relatively small weights can be used in the manufacture of the discs.

Since various modications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claim without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.

What I claim as my invention is:

For use in playing a lawn bowling game, or the like, a disc comprising a substantially flat circular body formed from relatively light weight material, said body having a flat face at one side thereof, a concave face at the opposite side, and a convex peripheral edge on which it is .adapted to be rolled, an insert of relatively heavy material embedded centrally in said one side of said body ush with said flat face thereof, and a shoulder-shaped handle provided centrally on `and disposed entirely within the concavity of said concave face of said body to facilitate picking up thereof, said heavy insert at one side and the concavity at the opposite side of the body rendering the same unbalanced when standing on said convex peripheral edge whereby to laterally deflect the disc from a straight line path when rolled.
