Abstract
Abstract A machine for automatically shooting or propelling a hockey puck is described. The machine includes apparatus for automatically issuing a hockey puck from a hopper. The puck is then dropped into an aiming chute from which it is propelled by a piston driven hammer. The aiming chute is adapted to be raised or lowered to propel the puck therefrom at different levels off of the ice. For ease in maneuvering across the ice, the machine is placed on wheels.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
140 words
A hockey practice device for propelling hockey pucks in a given direction, and said device comprising: a frame; a body portion disposed on said frame; a chute having a first end pivotally mounted to said frame and a second end for propelling hockey pucks therefrom; a hopper extending through said body portion and being interconnected to said chute to dispense hockey pucks into said chute; a plunger extending into said chute and adapted to engage the hockey puck dispensed therein; a link having one end pivotally mounted to said plunger and the other end pivotally mounted to the top of said body portion; a piston-cylinder assembly secured to said frame and including a piston having a shaft pivotally mounted to said link; means for actuating said piston-cylinder assembly and thereby causing the hockey puck to be propelled from said chute.
Claim 2
Dependent Claim
140 words
A hockey practice device for propelling hockey pucks in a given direction, and said device comprising: a frame; a body portion disposed on said frame; a chute having a first end pivotally mounted to said frame and a second end for propelling hockey pucks therefrom; a hopper extending through said body portion and being interconnected to said chute to dispense hockey pucks into said chute; a plunger extending into said chute and adapted to engage the hockey puck dispensed therein; a link having one end pivotally mounted to said plunger and the other end pivotally mounted to the top of said body portion; a piston-cylinder assembly secured to said frame and including a piston having a shaft pivotally mounted to said link; means for actuating said piston-cylinder assembly and thereby causing the hockey puck to be propelled from said chute.
Claim 3
Dependent Claim
48 words

The hockey practice device as defined in claim 1 and further comprising means for adjusting the angle of said chute.
Claim 5
Dependent Claim
62 words
The hockey practice device of claim 3 wherein said means for adjusting the angle of said Chute comprises a pulley rotatably mounted on said body portion above said chute; a chute angular position control; and a cable passing over said pulley and coupled between said control and said chute; whereby the vertical angular position of said chute is positionable by said control.
Claim 6
Dependent Claim
35 words
The hockey practice device as defined in claim 1 wherein said hopper is cylindrically shaped and is positioned to extend vertically above said chute and is adapted to hold a stack of hockey pucks therein.
