First Claim
1. A ball launcher comprising a barrel, a plunger positioned in the barrel for slideable motion therein, the front portion of the barrel having a cavity for retaining a plurality of compressible balls therein, said cavity having a rigid constriction at the front of the cavity, a carriage and spring means supported in said barrel and positioned in the front cavity thereof, said carriage positioned to contact one of said balls, said spring means urging said carriage to urge said balls towards said constriction, said carriage having a cuplike portion in the shape of a portion of a ball to be received therein, and a plurality of ears for sliding on the interior of the barrel, said ears being spaced apart about the said carriage and having a curved surface in contact with said barrel inside surface to prevent the carriage from skewing in said barrel and to permit air to flow back and forth between said ears, said plunger back and forth motion towards and away from said carriage and said constriction forcing said balls one at a time to squeeze past said constriction and be launched.

Abstract
A ball launcher for launching a plurality of soft closed cell plastic compressible balls, one ball at a time, by causing a plurality of balls in a line, one ball at a time (each time the plunger is moved back and forth), to squeeze past a constriction at the front of the launcher. The front most ball in the line of balls, to be launched, is urged against the constriction by a resilient biasing carriage engaging the rear most ball in the line of balls.
