Sx-70 Film Pack With Battery Hold Down Structure
US Patent:
4324473, Apr 13, 1982
Filed:
Oct 3, 1980
Appl. No.:
6/193618
Inventors:
Edward H. Coughlan - Norwood MA
Assignee:
Polaroid Corporation - Cambridge MA
International Classification:
G03B 1726
US Classification:
354276
Abstract:
A photographic film pack for use with battery energized photographic apparatus and including a film container having a blocking member therein for capturing an end portion of a flat battery within the container and blocking its movement away from a rear wall of the container in response to an upwardly directed force applied to the battery terminals by resiliently mounted battery contact members in the apparatus which extend into the container through access openings in the rear wall. This construction minimizes the depth of contact penetration required for good electrical contact and increases the tolerances of the shape of battery contact members which may achieve such minimum penetration.
Shutter Latch System With Automatic Release For Shock Damping Member
US Patent:
4017876, Apr 12, 1977
Filed:
Jan 13, 1976
Appl. No.:
5/648661
Inventors:
Edward H. Coughlan - Dedham MA
George D. Whiteside - Lexington MA
George D. Whiteside - Lexington MA
Assignee:
Polaroid Corporation - Cambridge MA
International Classification:
G03B 908
G03B 1738
G03B 1738
US Classification:
354230
Abstract:
This invention relates to an improvement to a photographic camera of the type having an automatic shutter latch mechanism which may be released in response to initial shutter blade movement resulting from energization of the shutter drive means and which may thereafter be moved into position to accommodate relatching of the shutter blades in response to film advancement. The shutter latch mechanism additionally includes a shock stabilizing arrangement to inhibit the accidental unlatching of the shutter blade mechanism resulting from shutter blade movement occasioned through extraneous vibration, sudden shock, or otherwise. The improvement resides in the automatic shutter latch mechanism which includes means responsive to the displacement of the latch when effecting the release of the shutter blade mechanism for inhibiting the operative influence of the shock stabilizing means on the blade mechanism until the blade mechanism is returned to its arrangement wherein it is retainable by the latch.
