Appliance for controllably altering the trajectory of a kicked American football

机译:可控制地改变踢美式足球轨迹的设备

摘要

A device for controllably altering trajectory of a kicked football includes a member removably insertable in a recess of a tee. The device is used in any one of three ways. First, it may be placed within the forward recess of the tee to combine with the ball receiving recess to completely enclose the tip of the football about its periphery. Second, a protrusion of the device may be placed in front of and slightly to the right of the centerline of the football. After the football is kicked, the tip of the football strikes this protrusion, causing the football to be deflected and to hook to the left. Third, the projection is in front of and slightly to the left of the centerline of the football. After the football is kicked, the tip strikes the projection, causing the ball to travel slightly to the right.
