Abstract
Abstract A toy apparatus is disclosed in which a launcher is utilized to propel a wheel. The launcher comprises an output shaft upon which the wheel is mounted. The shaft is rotatably driven by a gear train with the input gear thereof being connected to a slidable gear rack. The gear rack is hand manipulated to slide within a guideway formed in the launcher. The input gear is floatingly mounted within the launcher to positively drive the gear train in the forward direction, when the gear rack travels in one direction along the guideway, and to move out of engagement with the gear train when the gear rack moves in the other direction along the guideway. This uncoupling movement enables the gear rack to repeat its drive cycle while the gear train is still moving in the forward direction. In this manner, the gear rack need not be completely withdrawn from the guideway to repeat its drive cycles. These repeated drive cycles greatly increase the rotational speed of the output shaft before actual launching. A wheel ejector is pivotally mounted adjacent the output shaft and is slidingly coupled to the gear rack to pivot and force the wheel off of the shaft when the gear rack is finally withdrawn completely from the guideway.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
232 words
A toy launching apparatus comprising: a housing; an output shaft rotatably mounted within and extending partially out of said housing, the portion of the shaft extending out of the housing having means adapted to support a rotatable member in driving relation therewith; means for rotatably driving said output shaft, said means comprising a gear train, including an input pinion on a shaft, rotatably mounted within said housing coupled to said output shaft, and a gear rack movably mounted in a guideway in said housing and drivingly connected to the input pinion of said gear train, said gear rack being movable in one direction of the guideway to impart a rotary motion to the input pinion and the rest of the gear train, said means further comprising means for uncoupling said input pinion from the rest of said gear train during the movement of said gear rack in the opposite direction of the guideway to enable the gear rack to repeat its driving cycle while said output shaft continues the rotary movement imparted by the previous driving cycle, in order to increase the rotational sPeed of the gear train and said output shaft; and ejector means mounted on said housing responsive to appropriate movement of the gear rack at the end of the driving cycle for automatically forcing the rotatable member off of the output shaft to launch the rotatable member in motion.
Claim 2
Dependent Claim
232 words
