Abstract
Abstract An electromechanical simulation of a football game including a plurality of films showing different actual football plays and a projection system for showing the film. Provision is made for selection of offensive and defensive plays respectively from a plurality of choices. The particular selections operate electrical switches, with the combined selection determining the particular film to be shown. The selection is accomplished through a motor driven gearing associated with a circular rack which holds a plurality of films for alignment with the projector. To introduce an additional element of chance into the device, switches are provided which override the offensive and defensive play selections, and position the rack randomly. A mockup of a football field is included so as to show the position of the ball as the game proceeds.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
A system for simulating the offensive and defensive tactics of a sporting contest involving two opponents comprising: a projector-screen display means; a movable rack for containing separate holders for a plurality of film strips, each strip depicting a different single play; an offensive switch settable to a predetermined number of positions; a defensive switch settable to a predetermined number of positions, motor means for moving said rack; means coupling said motor means to said offensive and defensive switches so that the combined position of said switches determines the final position of said rack; a film advance and return motor means associated with said rack for driving the film in said holder as selected by said final rack position so as to be projected onto said screen by said projector; and means for overriding said switches and controlling the position of said rack at random intervals.
Claim 2
Independent Claim
145 words
A system for simulating the offensive and defensive tactics of a sporting contest involving two opponents comprising: a projector-screen display means; a movable rack for containing separate holders for a plurality of film strips, each strip depicting a different single play; an offensive switch settable to a predetermined number of positions; a defensive switch settable to a predetermined number of positions, motor means for moving said rack; means coupling said motor means to said offensive and defensive switches so that the combined position of said switches determines the final position of said rack; a film advance and return motor means associated with said rack for driving the film in said holder as selected by said final rack position so as to be projected onto said screen by said projector; and means for overriding said switches and controlling the position of said rack at random intervals.
Claim 3
Dependent Claim
27 words
The system of claim 1 further comprising, cam means mounted on said rack for actuating said offensive and defensive switches in response to movement of said rack.
Claim 4
Dependent Claim
24 words
The system of claim 1 wherein said rack is a circular drum and said film holders are mounted about the periphery of said rack.
Claim 5
Dependent Claim
77 words
The system of claim 3 wherein said film holders comprise; a first storage chamber; a second storage chamber; a guide channel between said first and second storage chambers; an aperture in said guide channel for placing said film between said projector and said screen; and film advancing means associated with said guide channel for advancing said film through said channel into said second storage chamber and returning said film from said second chamber to said first chamber.
Claim 6
Dependent Claim
64 words
The system of claim 4 where said film advancing means comprises: sprocket holes in said film; a movable plate; a plurality of parallel pins extending outwardly from and substantially parallel with said plate, said fingers being spaced so as to engage said sprocket holes in said film; and motor means for driving said plate in a rectilinear motion in the plane of said plate.
Claim 7
Dependent Claim
40 words
The system of claim 5 wherein the outermost of said plurality of pins are oppositely spring biased and rotatable in opposite direction, and further comprising sections at either end of said film strip having the sprocket holes cut out therefrom.
Claim 8
Dependent Claim
113 words
A game for providing selection of offensive and defensive tactics comprising; a film projector including a screen; a plurality of holders containing individual film strips and movable into projecting alignment with said projector; motor means for moving said holders; first switching means movable to a plurality of positions; second switching means movable to a plurality of positions; circuit means connecting said first and second switching means so as to control the operation of said motor means In accordance with the position of said first and second switch means; and third switching means connected to said circuit means for overriding said first and second switching means at random intervals for operation of said motor.
Claim 9
Dependent Claim
113 words
A game for providing selection of offensive and defensive tactics comprising; a film projector including a screen; a plurality of holders containing individual film strips and movable into projecting alignment with said projector; motor means for moving said holders; first switching means movable to a plurality of positions; second switching means movable to a plurality of positions; circuit means connecting said first and second switching means so as to control the operation of said motor means In accordance with the position of said first and second switch means; and third switching means connected to said circuit means for overriding said first and second switching means at random intervals for operation of said motor.
