    • A shuffleboard type of game in which a game board has a series of flat surfaced steps one of which is the highest step at one end of the series and one of which is the lowest step at the opposite end of the series, with the plurality of steps having progressively lower elevations from the highest toward the lowest step. A propelling device in the form of a chute is connected to the highest step for propelling down the steps a gamepiece which frictionally slides along the steps, the steps being assigned different scores so that the score is determined by that step at which a gamepiece stops moving.
    • 滑板游戏类型,其中游戏板具有一系列平坦的表面步骤,其中一个是在该系列的一端的最高台阶,其中一个是在该系列的相对端的最低阶,其中多个 步骤从最高到最低的步骤逐渐降低。 滑道形式的推进装​​置被连接到最高级,用于推动台阶沿着台阶摩擦地滑动的一个游戏者,该步骤被赋予不同的分数,使得得分由游戏者停止移动的那个步骤确定 。

    • An air gun where a series of spherical projectiles in a gun barrel are fired by air pressure one after the other out through the muzzle end of the barrel. The barrel has at its muzzle end a resilient sleeve through which each projectile will be propelled in response to the presence of sufficient air pressure behind each projectile to propel it through the resilient sleeve. This sleeve has a front end portion which is surrounded with clearance by the barrel to facilitate the movement of projectiles past it. Behind the resilient sleeve the barrel carries on one side of its interior a relatively small retarding block of resilient compressible material which engages the projectile next to the one which is about to be fired for retarding the movement of the series of projectiles toward the resilient sleeve, with the exception of that one projectile which is next to the sleeve to be next fired from the gun. This movement of the series of projectiles through the barrel is also caused by the air pressure behind the projectiles. Thus the same air pressure source behind the projectiles is utilized both for feeding the projectiles forwardly and for propelling the projectiles out of the gun.
    • 一个气枪,枪管中的一系列球形射弹通过气压一个接一个地通过枪管的枪口端射出。 枪管在其枪口端部具有弹性套筒,每个抛射体将被响应于在每个抛射体后面存在足够的空气压力以推动其通过弹性套筒而被推进。 该套筒具有前端部,该前端部被筒的间隙包围以便于射出物通过其移动。 在弹性套筒的后面,筒体在其内部的一侧承载弹性可压缩材料的相对较小的延迟块,该弹性可压缩材料与将要被点燃的射弹接合,以延迟一系列射弹朝向弹性套筒的移动, 除了下一次从枪射出的套筒旁边的那个一枚弹药外。 这一系列的弹丸通过枪管的运动也是由射弹背后的空气压力造成的。 因此,射弹后面的相同的空气压力源被用来向前投射弹药并将射弹推出枪​​。

    • A soft ball has an outer shell of a resilient polymeric material and is partially filled with a fine, dry, granular solid. When rolled on a hard surface the drag of the granular solid and the work of flexing the shell slow the ball and bring it to a stop after rolling a relatively short distance. The intent is to simulate the roll of a hard Bocce ball on a yielding surface such as a lawn. The outer diameter of the soft ball may be about 3 3/8 inches, the thickness of the shell may be from 0.050 to 0.080 inches, and the weight of the soft ball may be about 12 ounces.
    • 软球具有弹性聚合材料的外壳,并且部分地填充有细的干燥的颗粒状固体。 当在硬表面上滚动时,颗粒状固体的拖动和使外壳弯曲的工作使球减慢,并在滚动相对较短的距离后将其停止。 目的是模拟一个硬的Bocce球在屈服表面如草坪上的滚动。 软球的外径可以为约3 3/8英寸,壳的厚度可以为0.050至0.080英寸,软球的重量可以为约12盎司。
