Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
151 words
A photographic device for showing distance lapse motion pictures comprising an exercise bicycle having a driven wheel, a projector being mounted adjacent said exercise bicycle, having a film transport for moving a single frame of film in said projector and mechanical means connecting said driven wheel to said film transport and capable of moving said film a frame at a time in coordination with the rotation of said driven wheel, consisting of a cam being connected to said driven wheel, a driving fork being operatively connected to said cam for being moved back and forth, a gear being connected to said film transport and operatively connected to said driving fork, a spring loaded pin capable of preventing said gear from slipping back when said teeth are disengaged, whereby said pin in one prong will disengage said gear teeth as said gear is rotated by engaging a second prong of said fork.
Claim 2
Dependent Claim
151 words
A photographic device for showing distance lapse motion pictures comprising an exercise bicycle having a driven wheel, a projector being mounted adjacent said exercise bicycle, having a film transport for moving a single frame of film in said projector and mechanical means connecting said driven wheel to said film transport and capable of moving said film a frame at a time in coordination with the rotation of said driven wheel, consisting of a cam being connected to said driven wheel, a driving fork being operatively connected to said cam for being moved back and forth, a gear being connected to said film transport and operatively connected to said driving fork, a spring loaded pin capable of preventing said gear from slipping back when said teeth are disengaged, whereby said pin in one prong will disengage said gear teeth as said gear is rotated by engaging a second prong of said fork.
Claim 3
Dependent Claim
144 words
A photographic device for showing distance lapse motion pictures comprising an exercise bicycle having a driven wheel, a projector being mounted adjacent said exercise bicycle, having a film transport for moving a single frame of film in said projector and mechanical means connecting said driven wheel capable of moving said film a frame at a time in coordination with the rotation of said driven wheel, consisting of a crank connected to said driven wheel, a driving fork operatively connected to said crank for being moved back and forth, a gear being connected to said film transport and operatively connected to said driving fork, a spring loaded pin capable of preventing said gear from slipping back when said teeth are disengaged, whereby said pin in one prong disengages said gear teeth as said gear is being rotated by engaging a second prong of said fork.
Claim 4
Dependent Claim
144 words
A photographic device for showing distance lapse motion pictures comprising an exercise bicycle having a driven wheel, a projector being mounted adjacent said exercise bicycle, having a film transport for moving a single frame of film in said projector and mechanical means connecting said driven wheel capable of moving said film a frame at a time in coordination with the rotation of said driven wheel, consisting of a crank connected to said driven wheel, a driving fork operatively connected to said crank for being moved back and forth, a gear being connected to said film transport and operatively connected to said driving fork, a spring loaded pin capable of preventing said gear from slipping back when said teeth are disengaged, whereby said pin in one prong disengages said gear teeth as said gear is being rotated by engaging a second prong of said fork.
Claim 5
Dependent Claim
293 words
A photographic device for showing distance lapse motion pictures comprising an exercise bicycle having a driven wheel, a projector being mounted adjacent said exercise bicycle, having a film transport for moving a single frame of film in said projector and electrical means connecting said film transport to said driven wheel capable of moving said film a frame at a time in coordination with the rotation of said driven wheel, consisting of a cam being connected to said driven wheel, a pair of electric switches being operatively connected to said cam for being alternately closed, a pair of solenoids each being electrically connected to one of said switches for being activated by said switches, a common iron core operatively mounted in said solenoids for being driven back and forth, and a pivotally mounted driving fork being operatively connected to said iron core, a gear being connected to said film drive and operatively connected to said driving fork, a spring loaded pin being positioned for preventing said gear from slipping back when said teeth are disengaged, whereby said pin in one prong of said fork is pushed out by said spring behind said pin when said prong disengages said gear teeth and said pin is pushed back into said prong by the lower teeth as said gear is being rotated by engaging a second prong of said fork, a pair of switches being operatively connected to said fork and capable of disconnecting said solenoids from each one of said cam switches at the end of the travel of said core, connecting an unactivated one of said solenoids from the other cam switch, whereby said solenoid circuits open after the moving of said iron core, in event said driven wheel stops rotating with said switch closed.
Claim 6
