Abstract
Abstract An apparatus for projecting hockey pucks from a puck storage chamber. A sweeper attached to the end of a rod is rotatable coupled to a support and driven by a motor or hand crank through the rod. The storage chamber has an opening communicating with the sweep path. A plate and index arm is rotatably coupled to the support for movement from a puck retaining position adjacent the chamber opening to a puck passing position away from the chamber opening. A puck is fed by gravity from the chamber into the sweep path where it is struck by the sweeper and projected outwardly. A puck retrieval and storage chamber comprising a tubular puck sized body has pivotally mounted detents at one open end. A spring loaded rod coupled to the detents holds them in a normally puck retaining position partly obscuring the opening, but can be manipulated to retract the detents to permit entry and exit of pucks from the tube.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
An apparatus for projecting hockey pucks comprising: a support; a sweeper rotatably coupled to said support to rotate through a sweep path; means for rotating said sweeper through said sweep path, said rotating means being coupled to said sweeper; a puck storage chamber having an opening communicating with said sweep path; and a retainer means movable to a puck retaining position adjacent said chamber opening and to a puck passing position away from said chamber opening, said retainer means comprising a plate rotatably coupled to said support, and an index arm connected to said plate to rotate said plate into said puck retaining and puck passing positions, whereby a puck from said storage chamber is struck by said sweeper during rotation through said sweep path and projected outwardly from said apparatus.
Claim 2
Independent Claim
131 words
An apparatus for projecting hockey pucks comprising: a support; a sweeper rotatably coupled to said support to rotate through a sweep path; means for rotating said sweeper through said sweep path, said rotating means being coupled to said sweeper; a puck storage chamber having an opening communicating with said sweep path; and a retainer means movable to a puck retaining position adjacent said chamber opening and to a puck passing position away from said chamber opening, said retainer means comprising a plate rotatably coupled to said support, and an index arm connected to said plate to rotate said plate into said puck retaining and puck passing positions, whereby a puck from said storage chamber is struck by said sweeper during rotation through said sweep path and projected outwardly from said apparatus.
Claim 3
Dependent Claim
18 words
The apparatus as claimed in claim 1 wherein said support includes a base horizontally positioned below said sweeper.
Claim 4
Dependent Claim
54 words
The apparatus as claimed in claim 1, including a retaining wall coupled to said support adjacent to the periphery of said sweep path and enclosing a portion of said sweep path, said retaining wall providing an exit communicating with said sweep path to permit the escape of a hockey puck from said sweep path.
Claim 5
Dependent Claim
49 words
The apparatus as claimed in claim 1, including a plurality of said puck storage chambers, and wherein said retainer means is movable to a plurality of said puck passing positions, each of said puck passing positions allowing passage of a puck from only one of said puck storage chambers.
Claim 6
Dependent Claim
44 words
The apparatus as claimed in claim 1, wherein said rotating means comprises a vertical shaft connected to said sweeper, concentric to the axis of rotation of said sweeper; and a crank extending outwardly from an upper portion of said shaft to turn said shaft.
Claim 7
Dependent Claim
46 words
The apparatus as claimed in claim 1, wherein said rotating means comprises a vertical shaft connected to said sweeper concentric to the axis of rotation of said sweeper; a motor operatively coupled to said shaft to rotate said shaft; and a controller for activating said motor.
Claim 8
Dependent Claim
69 words
The apparatus as claimed in claim 1, including in combination a puck retrieval and storage chamber comprising a tubular body having at least one open end; at least one pivotally mounted detent adjacent said open end; and a spring loaded rod coupled to said detent to move said detent from the spring loaded normally closed position in said open end to an open position out of said open end.
