Abstract
Abstract A photographic camera for producing photographic exposures and igniting selected photoflash lamps linearly arrayed in timed sequence therewith includes terminals of magnetizable material for mounting a photoflash lamp assembly and establishing electrical contact between the assembly and the camera. The use of terminals composed of magnetizable materials for mounting and establishing electrical contact allows the user to easily remove and replace the photoflash lamp assembly when all the bulbs therein have been ignited.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
A photographic camera usable in conjunction with a photoflash lamp assembly supporting linearly arrayed photoflash lamps for ignition to illuminate a scene to be photographed, said assembly having contacts for conducting electrical current to select ones of said lamps, said camera comprising: a. means for producing photographic exposures; alignment means for positioning said assembly to simultaneously array photoflash lamps therewithin in an operative position for illuminating said scene; b. circuit means for electrically energizing said photoflash lamps supported by said assembly in timed relationship to photographic exposure production; and c. terminal means magnetically engageable with said contacts of said assembly for removably retaining said assembly of linearly arrayed photoflash lamps upon said alignment means and for electrically connecting said contacts and said circuit means.
Claim 2
Dependent Claim
124 words
A photographic camera usable in conjunction with a photoflash lamp assembly supporting linearly arrayed photoflash lamps for ignition to illuminate a scene to be photographed, said assembly having contacts for conducting electrical current to select ones of said lamps, said camera comprising: a. means for producing photographic exposures; alignment means for positioning said assembly to simultaneously array photoflash lamps therewithin in an operative position for illuminating said scene; b. circuit means for electrically energizing said photoflash lamps supported by said assembly in timed relationship to photographic exposure production; and c. terminal means magnetically engageable with said contacts of said assembly for removably retaining said assembly of linearly arrayed photoflash lamps upon said alignment means and for electrically connecting said contacts and said circuit means.
Claim 3
Dependent Claim
104 words
A photographic camera according to claim 1 wherein said terminal means comprises: a. spaced electrically conductive terminal members fixed within said alignment means for establishing electrical contact between said contacts of said linearly arrayed photoflash lamps and said circuit means and for mounting said linearly arrayed photoflash lamps upon said camera; and b. stationary electrically nonconductive magnetizing means fixed within said alignment means and positioned between said spaced terminal members for magnetizing said terminal members, said terminal members being operative to receive and retain in engagement said photoflash assembly contacts when so magnetized to provide said electrical contact as well as said assembly support.
Claim 4
Dependent Claim
38 words
A photographic camera according to claim 2 wherein said electrically nonconductive magnetizing means is present as a stationary ceramic magnet operable to magnetize said electrically conductive terminal members and to electrically insulate said terminal members from each other.
Claim 5
Dependent Claim
40 words
A photographic camera according to claim 1 wherein said alignment means comprises means defining a surface deformation adjacent said terminal means for positioning said assembly to simultaneously array said photoflash lamps therewithin in an operative position for illuminating said scene.
Claim 6
Dependent Claim
226 words
A photographic camera usable in conjunction with a photoflash lamp assembly supporting linearly arrayed photoflash lamps for ignition to illuminate a scene to be photographed, said assembly having contacts for conducting electrical current to select ones of said lamps, said camera comprising: a. means for producing photographic exposures; alignment means for positioning said assembly to simultaneously array photoflash lamps therewithin in an operative position for illuminating said scene; b. circuit means for electrically energizing said photoflash lamps supported by said assembly in timed relationship to photographic exposure production; c. a pair of spaced, electrically conductive terminal members for establishing the electrical contact between said linearly arranged lamps and said circuit means and for magnetically mounting said assembly of linearly arrayed photoflash lamps upon said camera; d. stationary electrically nonconductive magnetizing means interposed between said spaced contact members and fixed within said alignment means for magnetizing said members, thereby enabling said members tO magnetically engage said contacts of said photoflash assembly when said assembly is contiguous thereto, said magnetic engagement being effective to mount said assembly and effect electrical connection between said photoflash lamp assembly contact members and said terminal means; and e. means defining a surface deformation adjacent said terminal means cooperable with means defining a surface deformation of complimentary configuration upon said assembly for establishing a predetermined orientation of said assembly relative to said camera.
Claim 7
Dependent Claim
226 words
A photographic camera usable in conjunction with a photoflash lamp assembly supporting linearly arrayed photoflash lamps for ignition to illuminate a scene to be photographed, said assembly having contacts for conducting electrical current to select ones of said lamps, said camera comprising: a. means for producing photographic exposures; alignment means for positioning said assembly to simultaneously array photoflash lamps therewithin in an operative position for illuminating said scene; b. circuit means for electrically energizing said photoflash lamps supported by said assembly in timed relationship to photographic exposure production; c. a pair of spaced, electrically conductive terminal members for establishing the electrical contact between said linearly arranged lamps and said circuit means and for magnetically mounting said assembly of linearly arrayed photoflash lamps upon said camera; d. stationary electrically nonconductive magnetizing means interposed between said spaced contact members and fixed within said alignment means for magnetizing said members, thereby enabling said members tO magnetically engage said contacts of said photoflash assembly when said assembly is contiguous thereto, said magnetic engagement being effective to mount said assembly and effect electrical connection between said photoflash lamp assembly contact members and said terminal means; and e. means defining a surface deformation adjacent said terminal means cooperable with means defining a surface deformation of complimentary configuration upon said assembly for establishing a predetermined orientation of said assembly relative to said camera.
