Abstract
Abstract Hockey puck practice shooting apparatus includes a target comprising a housing with a rotatable disc-shaped shield rotatably mounted on its front wall. The front wall is formed with holes large enough to receive a hockey puck and spaced one or more radial distances from the axis of the shield and the shield is provided with one or more arcuate slots of equal radii with the holes so as to register with the holes for a length of time proportional to the angular length of the slots and the rotational velocity of the shield. A puck ejector is electromechanically synchronized with the operation of the shield.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
Hockey puck practice shooting apparatus comprising target structure having a vertical wall formed with at least one hole of sufficient size to permit the passage therethrough of a puck, a shield rotatably mounted on said structure forward of said wall with its center of rotation spaced radially from said hole, said shield being formed with an arcuate slot spaced the same distance from the axis of rotation as said hole and registrable intermittently with said hole to expose the same during continued rotation of said shield, and means for ejecting single pucks in selected time sequence with respect to the exposure and closure of said target holes by said shield.
Claim 2
Dependent Claim
110 words
Hockey puck practice shooting apparatus comprising target structure having a vertical wall formed with at least one hole of sufficient size to permit the passage therethrough of a puck, a shield rotatably mounted on said structure forward of said wall with its center of rotation spaced radially from said hole, said shield being formed with an arcuate slot spaced the same distance from the axis of rotation as said hole and registrable intermittently with said hole to expose the same during continued rotation of said shield, and means for ejecting single pucks in selected time sequence with respect to the exposure and closure of said target holes by said shield.
Claim 3
Dependent Claim
16 words
Apparatus according to claim 1 including power means for rotating said shield at a uniform rate.
Claim 4
Dependent Claim
70 words
Apparatus according to claim 1 wherein said ejection means comprises a solenoid having its plunger retracted and projectible responsive to energization of said solenoid, electrical switch means on said target structure arranged to close momentarily at selective rotational positions of said shield, electrical circuit means including said switch means and said solenoid whereby upon closure of said switch means said solenoid is energized causing its plunger to eject a puck.
Claim 5
Dependent Claim
36 words
Apparatus according to claim 3 wherein said electrical switch means comprises at least one switch mounted on said target structure and an actuator for said switch rotatable with said shield and operatively engageable with said switch.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 4 wherein there are at least two target holes, there being one of said switches for each of said target holes.
Claim 7
Dependent Claim
21 words
Apparatus according to claim 5 including a manual control switch device in series with each of said switches and said solenoid.
Claim 8
Dependent Claim
38 words
Apparatus according to claim 1 including at least two holes at different radii from the axis of rotation of said shield, said shield being formed with at least two arcuate slots of equal radii respectively with said holes.
Claim 9
Dependent Claim
13 words
Apparatus according to claim 7 wherein said arcuate slots are equiangular in length.
Claim 10
Dependent Claim
34 words
Apparatus according to claim 8 wherein there are four of said holes spaced equiangularly about the axis of rotation of said shield and two of said slots the centers of which are 180* apart.
