Claim 7

In a view camera having a camera bed, a front plate with lens mounting means thereon, a rear film and ground glass carrying plate, and manually operable means to adjust the position of said plates relative to said camera bed, the improvement comprising said manually operable means being a finger knob mounted on a shaft, said finger knob having a finger engaging portion on the end of said shaft, a resilient friction disc adjacent the end of said finger engaging portion displaced from said end shaft, and a locking member adjacent the other end of said finger engaging portion, said finger engaging portion being slidable along the longitudinal extent of said shaft upon rotation of said locking member whereby said friction disc is compressed between said finger engaging portion of said knob and the member upon which said manually operable means is mounted.

Claim 8

A view camera comprising a tripod mount member, a camera bed having track assembly means with two parallel side rails rigidly attached to each other by cross-member means, said track assembly means having track means thereon that cooperate with camera bed moving means associated with said tripod mount member so that said camera bed is movable with respect to said tripod mount member, a front lens carrying assembly and a rear ground glass and flim carrying assembly, both said front and rear assemblies having a depth track following member that is movable along said two parallel side rails, lateral track means pivotally attached to said depth track following member to be movable in a plane parallel to the plane of said two parallel side rails, a support frame base member carried by said lateral track means and movable with respect thereto, and an upstanding support arm attached to each end of said support frame base member to be perpendicular to said plane of said two parallel side rails, each of said support arms including a lower portion with a height extending arm chamber therein and an upper portion with a height extending arm in telescoping relationship with said chamber and movable with respect thereto.

Claim 9

A view camera comprising a tripod mount member, a camera bed having track assembly means with two parallel side rails rigidly attached to each other by cross-member means, said track assembly means having track means thereon that cooperate with camera bed moving means associated with said tripod mount member so that said camera bed is movable with respect to said tripod mount member, a front lens carrying assembly and a rear ground glass and flim carrying assembly, both said front and rear assemblies having a depth track following member that is movable along said two parallel side rails, lateral track means pivotally attached to said depth track following member to be movable in a plane parallel to the plane of said two parallel side rails, a support frame base member carried by said lateral track means and movable with respect thereto, and an upstanding support arm attached to each end of said support frame base member to be perpendicular to said plane of said two parallel side rails, each of said support arms including a lower portion with a height extending arm chamber therein and an upper portion with a height extending arm in telescoping relationship with said chamber and movable with respect thereto.
