Abstract
Abstract A motion picture camera wherein the conversion filter is movable with reference to the objective lens by a linkage whose input member is mounted in the pistol grip and a portion of which extends through a hollow fastener serving to separably connect the pistol grip with the housing. The input member is a slide which can be moved by hand and/or by means of a support for a flash unit or another source of artificial light. Various positions of the filter are indicated by symbols which are concealable by the input member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
In a motion picture camera, a combination comprising a camera housing; picture taking lens means mounted in said housing and having an optical axis; filter means for incident light, said filter means being mounted in said housing for movement with reference to said lens means between a plurality of positions including a first position of registry with said lens means in which said filter means extends across said optical axis and a second position out of registry with said lens means; handgrip means removably connected with said housing; and displacing means for moving said filter means with reference to said lens means, said displacing means including an input member movably mounted in said handgrip means and motion transmitting means separably connecting said input member with said filter means.
Claim 2
Dependent Claim
128 words
In a motion picture camera, a combination comprising a camera housing; picture taking lens means mounted in said housing and having an optical axis; filter means for incident light, said filter means being mounted in said housing for movement with reference to said lens means between a plurality of positions including a first position of registry with said lens means in which said filter means extends across said optical axis and a second position out of registry with said lens means; handgrip means removably connected with said housing; and displacing means for moving said filter means with reference to said lens means, said displacing means including an input member movably mounted in said handgrip means and motion transmitting means separably connecting said input member with said filter means.
Claim 3
Dependent Claim
41 words
A combination as defined in claim 11, wherein said input member is movable between a plUrality of positions each corresponding to a different position of said filter means, and further comprising indicating means for indicating the positions of said input member.
Claim 4
Dependent Claim
38 words
A combination as defined in claim 11, wherein said input member is reciprocable between first and second positions to thereby respectively move said filter means to said first and second positions by way of said motion transmitting means.
Claim 5
Dependent Claim
56 words
A combination as defined in claim 12, wherein said motion transmitting means comprises a reciprocable member operatively connected with said filter means and wiper means movably mounted in said handgrip means and operative to change the position of said reciprocable member in response to movement of said input member between said first and second positions thereof.
Claim 6
Dependent Claim
144 words
In a motion picture camera, a combination comprising a camera housing; picture taking lens means mounted in said housing and having an optical axis; filter means for incident light, said filter means being mounted in said housing for movement with reference to said lens means between a plurality of positions including a first position of registry with said lens means in which said filter means extends across said optical axis and a second position out of registry with said lens means; handgrip means; hollow fastener means securing said handgrip means to said housing; and displacing means for moving said filter means with reference to said lens means, said displacing means including an input member movably mounted in said handgrip means and motion transmitting means connecting said input member with said filter means, said motion transmitting means comprising a portion extending through said fastener means.
Claim 7
Dependent Claim
144 words
In a motion picture camera, a combination comprising a camera housing; picture taking lens means mounted in said housing and having an optical axis; filter means for incident light, said filter means being mounted in said housing for movement with reference to said lens means between a plurality of positions including a first position of registry with said lens means in which said filter means extends across said optical axis and a second position out of registry with said lens means; handgrip means; hollow fastener means securing said handgrip means to said housing; and displacing means for moving said filter means with reference to said lens means, said displacing means including an input member movably mounted in said handgrip means and motion transmitting means connecting said input member with said filter means, said motion transmitting means comprising a portion extending through said fastener means.
Claim 8
Dependent Claim
16 words
A combination as defined in claim 14, wherein said fastener means threadedly engages with said housing.
Claim 9
Dependent Claim

A combination as defined in claim 14, wherein said portion of said motion transmitting means comprising a member which is reciprocable in said fastener means between two positions each corresponding to a different position of said filter means with reference to said lens means, and means for biasing said member to one of said positions thereof.
Claim 10
Dependent Claim
139 words
In a motion picture camera, a combination comprising a camera housing; picture taking lens means mounted in said housing and having an optical axis; filter means for incident light, said filter means being mounted in said housing for movement with reference to said lens means between a plurality of positions including a first position of registry with said lens means in which said filter means extends across said optical axis and a second position out of registry with said lens means; handgrip means connected with said housing; displacing means for moving said filter means with reference to said lens means, said displacing means including an input member movably mounted in said handgrip means and motion transmitting means connecting said input member with said filter means; and a source of artificial light having a portion connected with said handgrip means.
Claim 11
Dependent Claim
139 words
In a motion picture camera, a combination comprising a camera housing; picture taking lens means mounted in said housing and having an optical axis; filter means for incident light, said filter means being mounted in said housing for movement with reference to said lens means between a plurality of positions including a first position of registry with said lens means in which said filter means extends across said optical axis and a second position out of registry with said lens means; handgrip means connected with said housing; displacing means for moving said filter means with reference to said lens means, said displacing means including an input member movably mounted in said handgrip means and motion transmitting means connecting said input member with said filter means; and a source of artificial light having a portion connected with said handgrip means.
Claim 12
Dependent Claim
21 words
A combination as defined in claim 15, wherein said handgrip means comprises means for movably supporting said portion of said source.
Claim 13
Dependent Claim
64 words
A combination as defined in claim 9, wherein said input member is movable to and from a given position corresponding to a predetermined position of said filter means with reference to said lens means, said portion of said source being movable with reference to said handgrip means to and from a preselected position in which it maintains said input member in said given position.
