Abstract
Abstract This invention relates to apparatus for simulating the movements of a sea or land craft including a screen on which the route to be traveled by the craft is shown, a projector for projecting an image of the craft on the screen, which projector is mounted for angular rotation about two perpendicular axes to enable the image to be moved in two perpendicular directions on the screen and a drive mechanism controlled by the user of the apparatus or by the navigator or driver of the craft for effecting angular rotation of the projector about its axes in dependence on the simulated direction and speed of the craft.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
248 words
Apparatus for reproducing the changing position of a simulated surface craft by projection of an image thereof on a screen comprising a screen onto which the image is projected, a projector for projecting an image of the craft on said screen, means for mounting said projector to rotate about two perpendicular axes, each being parallel to said screen so as to simulate direction of movement and speed of the image on said screen in any direction, means for rotating said projector selectively about at least one of said perpendicular axes, means for controlling the speed of and the extent of rotation of said rotation means in accordance with the speed and direction of and distance travelled by the simulated craft, said controlling means including at least one rotatable disc, means for controllably rotating said at least one disc at a speed corresponding to a selected speed of the craft, two spaced wheels on opposite sides of the center of said at least one disc, the peripheries of said wheels engaging the surface of said at least one disc, means for moving both of said wheels radially and simultaneously across the surface of said at least one disc in the same direction so as to vary the speed of rotation of said wheels inversely and means connecting each of said wheels to said means for rotating said projector about each of the perpendicular axes whereby the image projected on said screen follows a selected path at a selected speed.
Claim 2
Dependent Claim
248 words
Apparatus for reproducing the changing position of a simulated surface craft by projection of an image thereof on a screen comprising a screen onto which the image is projected, a projector for projecting an image of the craft on said screen, means for mounting said projector to rotate about two perpendicular axes, each being parallel to said screen so as to simulate direction of movement and speed of the image on said screen in any direction, means for rotating said projector selectively about at least one of said perpendicular axes, means for controlling the speed of and the extent of rotation of said rotation means in accordance with the speed and direction of and distance travelled by the simulated craft, said controlling means including at least one rotatable disc, means for controllably rotating said at least one disc at a speed corresponding to a selected speed of the craft, two spaced wheels on opposite sides of the center of said at least one disc, the peripheries of said wheels engaging the surface of said at least one disc, means for moving both of said wheels radially and simultaneously across the surface of said at least one disc in the same direction so as to vary the speed of rotation of said wheels inversely and means connecting each of said wheels to said means for rotating said projector about each of the perpendicular axes whereby the image projected on said screen follows a selected path at a selected speed.
Claim 3
Dependent Claim
47 words
Apparatus as claimed in claim 1 and further comprising means within said projector for forming the projected image of the craft and means for rotating the image-forming means about the axis of projection in accordance with the direction of the image as it moves across said screen.
Claim 4
Dependent Claim
28 words
Apparatus as claimed in claim 1 and further comprising a motor for driving said at least one disc, and means for selectively controlling the speed of said motor.
Claim 5
Dependent Claim
76 words
Apparatus as claimed in claim 1 and further comprising a motor, means connecting said motor to said two spaced wheels for moving said wheels radially across the surface of said at least one disc, means within said projector for forming the projected image of the craft, said connecting means also rotating the image-forming means within said projector about the axis of projection in accordance with the direction of the image as it moves across the screen.
Claim 6
Dependent Claim
29 words
Apparatus as claimed in claim 4 and further comprising means for controlling said connecting means in accordance with selected changes in direction of the projected image of the craft.
Claim 7
Dependent Claim
36 words
Apparatus as claimed in claim 4, and further comprising clutch means interposed between the motor and the spaced wheels whereby drift may be simulated even while the means for rotating the image-forming means is fully operable.
Claim 8
Dependent Claim
36 words
Apparatus as claimed in claim 1 wherein said controlling means includes two rotatable discs, rotating at the same speed and wherein the peripheries of each of said two spaced wheels engages one of said two discs.
Claim 9
Dependent Claim
78 words
Apparatus as claimed in claim 1, wherein the means for moving said two spaced wheels comprises two arms connected together at one end to form a 90* angle, two guide members slidably connected to the other ends of said arms, said spaced wheels being rotatably mounted on said guide members, whereby upon rotation of said connected arms about their junction, said guide members and said wheels will be moved across a diameter of said at least one disc.
Claim 10
Dependent Claim
95 words
Apparatus as claimed in claim 1, wherein the means for moving said two spaced wheels comprises two pairs of arms, each pair being connected together at one end to form a 90* angle and rotatable about parallel axes, two guide members, each being connected to the other end of each of said pair of arms, each of said spaced wheels being rotatably mounted on one of said guide member, whereby upon rotation of said pairs of arms said guide members and said wheels will be moved across a diameter of said at least one disc.
Claim 11
Dependent Claim
24 words
Apparatus as claimed in claim 1 and further comprising means for varying the pressure of the spaced wheels against said at least one disc.
Claim 12
Dependent Claim
31 words
Apparatus as claimed in claim 1 and further comprising means for receiving signals from a craft indicating its movement and location and means for controlling said controlling means in accordance therewith.
