Abstract
Abstract This specification discloses a machine for automatically shooting or propelling a hockey puck. The machine includes apparatus for automatically issuing a hockey puck from a hopper. The puck is then dropped onto a platform in the path of a motor drive energy storing spring which propells the puck in a desired direction. The energy storing spring is provided with two separate structures for adjusting the spring energy. The two separate structures for adjusting the energy in the spring are a pair of screws inserted in a pair of elongated slots at one end of the spring for adjustably attaching the spring to the motor drive shaft and a block pin adjustably positioned such that the other end of the spring will be deflected upon contact with the block pin once during each revolution of the spring.

Claim 1
Independent Claim
205 words
A hockey puck passer comprising a base platform having on elongated slot, a top plate having an elongated slot aligned with the elongated slot in said base platform, means supporting said top plate in selected spaced relation to said base platform, drive means including a driven shaft rotatably supported in said top plate, a bracket fastened to said driven shaft to provide a continuing cycle of rotation, an energy storing leaf spring, means adjustably fastening said leaf spring to said bracket, whereby said drive means through said driven shaft rotates said bracket and said energy storing leaf spring in a continous cycle of rotation, a block pin, means adjustably fastening said block pin for movement and support in said elongated slots in alignment with the rotatable path of said energy storing leaf spring, hopper means fastened to said top plate, whereby hockey pucks gravity fed find support upon said base platform in the rotatable path of said leaf spring to be successively engaged in each cycle of rotation by said leaf spring, said block pin blocking the path of free rotation of said leaf spring to thereby store energy in said leaf spring, said energy being released upon tHe continued rotation of said leaf spring.
Claim 2
Dependent Claim
205 words
A hockey puck passer comprising a base platform having on elongated slot, a top plate having an elongated slot aligned with the elongated slot in said base platform, means supporting said top plate in selected spaced relation to said base platform, drive means including a driven shaft rotatably supported in said top plate, a bracket fastened to said driven shaft to provide a continuing cycle of rotation, an energy storing leaf spring, means adjustably fastening said leaf spring to said bracket, whereby said drive means through said driven shaft rotates said bracket and said energy storing leaf spring in a continous cycle of rotation, a block pin, means adjustably fastening said block pin for movement and support in said elongated slots in alignment with the rotatable path of said energy storing leaf spring, hopper means fastened to said top plate, whereby hockey pucks gravity fed find support upon said base platform in the rotatable path of said leaf spring to be successively engaged in each cycle of rotation by said leaf spring, said block pin blocking the path of free rotation of said leaf spring to thereby store energy in said leaf spring, said energy being released upon tHe continued rotation of said leaf spring.
Claim 3
Dependent Claim
235 words
A hockey puck passer comprising a base platform, a top plate, means supporting said top plate in selected spaced relation to said base platform, drive means including a driven shaft rotatably supported in said top plate, a bracket fastened to said driven shaft, an energy storing leaf spring, means adjustably fastening said leaf spring to said bracket, whereby said drive means through said driven shaft rotates said bracket and said energy storing leaf spring in a continuous cycle of rotation, a block pin, (said means adjustably fastening said block pin in said top plate and said base plate comprises) a flange fastened to said top plate and said base platform, a stem having screw threads, means rotatably supporting said stem in said flange, a ''''U'''' shaped fixture, means fastening said fixture to said stem, and means fastening said block pin in said fixture whereby said stem adjustably positions said block pin in alignment with the rotatable path of said energy storing leaf spring, hopper means fastened to said top plate, whereby hockey pucks gravity fed find support upon said base platform in the rotatable path of said leaf spring to be successively engaged in each cycle of rotation by said leaf spring, said block pin blocking the path of free rotation of said leaf spring to thereby store energy in said leaf spring, said energy being released upon the continued rotation of said leaf spring.
Claim 4
