FIE-1b POWER SOURCE HOCKEY PUCK PRACTICE SHOOTING APPARATUS FIELD OF THE INVENTION The invention relates to practice devices for hockey and consists particularly in practice puck shooting apparatus. 1
SUMMARY OF THE INVENTION The invention provides means for determining and developing accuracy in shooting hockey pucks. In furtherance of this purpose, it provides accurately timed exposure of the target and synchronizes'the exposure of the target with the ejection of pucks from a magazine. It also provides means for exercising some manual control over the ejection of pucks from the magazine.

FIG. 4 is a front elevation view 'of the target apparatus.
FIG. 5 is a front elevational view of the target apparatus with the shield removed.
FIG. 6 is afront elevation view of the magazine.
FIG. 7 is an enlarged transverse sectional view along lines 7-7 of FIGS. 6 and 8.
FIG. 8 is an enlarged front elevation view of the dischargeend of the puck trough of the magazine illus-' trated in FIG. 6. 7
FIG. 9 is a wiring schematic of the apparatus;
DESCRIPTION OF THE PREFERRED EMBODIMENT The numeral 1 denotes the usual hockey target or goal. The numeral 2 refers generally to the target structure and the numeral 3 to a puck magazine constructed in accordance with the invention,
The goal structure 1 includes a box-like housing having a vertical front wall 5, a rear wall 7, side walls 9 and top and bottom walls 11 and 13. Front wall 5 is formed with four holes 15 and 17 of sufficient size to permit the passage through them of a hockey puck. Holes 15 and 17 are spaced equiangularly about a central hole 19, holes 15 being vertically aligned with central hole 19 and spaced equidistantly therefrom and holes 17 being horizontally aligned with hole 19 and being spaced equidistantly therefrom a somewhat greater distance than the spacing of holes 15. I
In order to limit the duration of exposure of the target holes 15 and 17, a disc-shaped shield 21 is mounted on a shaft 23 which passes through central hole 19 and a corresponding central hole 25 in the rear wall of the target housing, and shield 21 is formed with two arcuate slots 27 and 29, the centers of which are 180 apart and the radii of which correspond respectively to the radii of holes 15 and 17 from center hole 19. Arcuate slots 27 and 29 are of the same angular length.
It will be evident from the foregoing that if shield 21 is rotated at uniform speed, slots 27 and 29respectively will expose target holes 15 and 17 intermittently for an equal length of time. For driving shaft 23 and shield 21 at a desired speed, shaft 23 mounts a sheave 31 which is connected by belt 33 to a sheave 35 on the shaft of electric motor 37 mounted on bottom wall 13 of the target housing.
For feeding pucks to a player, magazine 3 comprises a pair of transversely spaced base members 39 extending horizontally rearwardly from the magazine and a pair of correspondingly spaced upright members 41. spaced apart transversely of the magazine and supporting a transversely inclined channel section trough 43, the lower end 45 of which opens into an oppositely downwardly inclined outlet trough 47 of similar cross section and a plurality of pucks P are normally seated in troughs 43 and 47. The bottom or outlet end 49 of outlet trough 47 is near the transverse midpoint of the magazine and at floor level and to the rear of outlet end 49 of outlet trough 47 a solenoid 51 is mounted with its axis normal to the general vertical plane of magazine 3, and its plunger 53 arranged to engage pucks P from the rear when the solenoid is energized, and eject the forwardly from the magazine to a shooting position on a pad 55 forward of the magazine. Except when sole noid 51 is energized to move plunger 53 forwardly, 'a spring 57anchored at 59 normally maintains plunger 53 retracted and rearward of magazine outlet 49. In order to synchronize the ejection of the pucks with the exposure of target holes 15 and 17 by slots 27 and 29, shaft 23 projects outwardly from rear wall 7 of the target housing and there mounts a timing disc 61. A bar 63 adjustably rotatably mounted on disc 61 mounts a switch actuator flap 65 on its outer end projecting slightly beyond the periphery of disc 61, and at each of the cardinal positions corresponding to the locations in the front wall'of holes 15 and 17 respectively are four momentary closure switches '67 adapted to be momentarily closed by the engagement of flap 65 with their plungers 69.
In the wiring schematic of F IG. 9, one wire 71 from the power source is connected to four switches 67. Wires 73 connect the respective switches 67 to corresponding manually actuable switches 75 on a control panel 77 which in turn is connected by a wire 79 to solenoid 51. The other side of the power source is connected by wire 81 to solenoid 51 so that as each target hole 15 or 17 is uncovered by. slots 27 and 29 of shield 21, corresponding rotation of timing disc 61 causes flap 65 to successively close momentary closure switches 67. Solenoid 51 will be energized each time switches 67 are closed, subject to the manual closure of switches 75, thereby ejecting pucks a selected length of time before exposure of target holes 15and 17 by shield 21. Switches 75 on control panel 77 permit manual variation of the duration of time the puck is available before exposure of the target holes in addition to the auto- I matic uniform timing providedby switches 67;
The details of the apparatus may be varied substantially without departing from the spirit of the invention and the exclusive use of such modifications as come within the scope of the appended claims is contemplated.
1. 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 holeto 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.
2. Apparatus according to claim 1 including power means for rotating said shield at a uniform rate.
3. 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.
4. Apparatus according to claim 3 wherein said electrical switch means comprises at least one switchmounted on said target structure and an actuator for said switch rotatable with said shield and operatively engageable with said switch.
5. 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.
6. Apparatus according to claim 5 including a manual control switch device in series with each of said switches and said solenoid.
7. Apparatus according to claim 1 including at least two holes at different radii from the axis of rota-tion of said shield, said shield being formed with at least two arcuate slots of equal radii respectively with said holes.
ters of which are apart.
