Abstract
Abstract A reader-filler machine adapted to insert sections of microfilm into selected chambers of a multi-chamber microfiche jacket, each chamber having an entry slot adjacent the front end of the jacket. The jacket to be loaded is placed on the inclined platform of a carriage that is shiftable stepwise in a path at right angles with respect to a film trackway. A retractable pusher is disposed at a position parallel to the trackway so that when the trackway is aligned with a particular chamber preparatory to film insertion, the pusher is then in registration with the adjacent chamber and when after the inserted film section is severed from the film on the trackway and the platform is indexed, the tail end of the cut film section which lies outside the entry slot is then aligned with the pusher which acts to push the tail end into the chamber to complete the insertion. The platform is provided with a retractable clamp which, when operative, engages the jacket to deflect the front end thereof downwardly in order to more effectively expose the entry slots and thereby facilitate the insertion of very thin film. The deflection of the jacket front end also serves to free the tail end of the cut film whereby the tail end is readily engaged by the pusher.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
182 words
A machine for cutting a relatively thin microfilm strip into sections and for inserting these secctions into the chambers of a protective jacket, each chamber having an inwardly-displaced film entry slot adjacent the front end of the jacket, said apparatus comprising: a. a platform for supporting said jacket, b. a film advancing mechanism including a trackway for advancing the film strip toward said platform, said platform being inclined relative to said trackway, c. retractable clamping means on said platform for engaging said jacket and to deflect the front end thereof downwardly whereby the entry slots on the jacket are more accessible to an advancing film, d. means to index the position of said platform relative to said trackway to register the film strip in said trackway with successive entry notches on said jacket, whereby a section of said strip may be inserted into a particular chamber, and e. a cutter interposed between said platform and said trackway to sever the inserted section from said strip, the tail end of said section being free relative to the deflected front end of said jacket.
Claim 2
Dependent Claim
182 words
A machine for cutting a relatively thin microfilm strip into sections and for inserting these secctions into the chambers of a protective jacket, each chamber having an inwardly-displaced film entry slot adjacent the front end of the jacket, said apparatus comprising: a. a platform for supporting said jacket, b. a film advancing mechanism including a trackway for advancing the film strip toward said platform, said platform being inclined relative to said trackway, c. retractable clamping means on said platform for engaging said jacket and to deflect the front end thereof downwardly whereby the entry slots on the jacket are more accessible to an advancing film, d. means to index the position of said platform relative to said trackway to register the film strip in said trackway with successive entry notches on said jacket, whereby a section of said strip may be inserted into a particular chamber, and e. a cutter interposed between said platform and said trackway to sever the inserted section from said strip, the tail end of said section being free relative to the deflected front end of said jacket.
Claim 3
Dependent Claim
27 words
A machine as set forth in claim 1 wherein said platform has a leading edge which is relieved to accomodate the deflection of said jacket front end.
Claim 4
Dependent Claim
33 words
A machine as set forth in claim 1 wherein said jacket is placed on said platform with its front end overhanging the leading edge of the platform to permit deflection of said overhang.
Claim 5
Dependent Claim
69 words
A machine as set forth in claim 1, futher including a pusher adjacent said trackway in registration with the film entry slot adjacernt that entry slot then in alignment with the trackway whereby when the platform is indexed, the tail extending from that entry slot as a result of the severing action is now in line with the pusher which is adapted to push the tail into the chamber.
Claim 6
Dependent Claim
38 words
A machine as set forth in claim 1, futher including optical means to project an image of said cutter and the adjacent frame image on said strip onto a viewing screen to verify the section to be inserted.
Claim 7
Dependent Claim
31 words
A machine as set forth in claim 1, further including means to apply pressure to the jacket chamber being filled to prevent a later-inserted film section from overriding a previously-inserted section.
Claim 8
Dependent Claim
26 words
A machine as set forth in claim 6, wherein said pressure applying means is a pressure roller mounted for rotation at a position above said platform.
Claim 9
Dependent Claim
34 words
A machine as set forth in claim 4, wherein said pusher includes a nose having a catcher formation to engage the end of said tail and to prevent it from dropping below said pusher.
Claim 10
Dependent Claim
53 words
A machine as set forth in claim 1, wherein said jacket is formed by two superposed panels which are held together by a series of parallel ribs which define said chambers, and said clamping means include a series of parallel teeth which when the clamping means is operative, apply pressure to said ribs.
Claim 11
Dependent Claim
92 words
In a machine for inserting a relatively thin microfilm strip into the chambers of a jacket formed by two superposed panels of transparent material which are held together by a series of parallel ribs to define said chambers, each chamber having an entry slot adjacent the front end of the jacket, said machine comprising an inclined platform to support said jacket for film insertion with respect to a horizontal film trackway, and means on said platform to deflect the front end of said jacket downwardly to facilitate film entry in said slots.
Claim 12
Dependent Claim
92 words
In a machine for inserting a relatively thin microfilm strip into the chambers of a jacket formed by two superposed panels of transparent material which are held together by a series of parallel ribs to define said chambers, each chamber having an entry slot adjacent the front end of the jacket, said machine comprising an inclined platform to support said jacket for film insertion with respect to a horizontal film trackway, and means on said platform to deflect the front end of said jacket downwardly to facilitate film entry in said slots.
Claim 13
Dependent Claim
29 words
In a machine as set forth in claim 10 wherein said jacket has location holes in the margin thereof and said platform has guide pins insertable in said holes.
Claim 14
Dependent Claim
28 words
In a machine as set forth in claim 10, wherein said deflection means is constituted by a clamp having projecting teeth which engage the ribs of said jacket.
Claim 15
Dependent Claim
34 words
In a machine as set forth in claim 12, further including a rotatable lever bar which in one angular position forces said clamp against said jacket and in another angular position relieves said pressure.
Claim 16
Dependent Claim
32 words
In a machine as set forth in claim 13, further including a clamping spring interposed between the bar and the clamp. The spring having spring fingers which are aligned with said teeth.
Claim 17
Dependent Claim
29 words
In a machine as set forth in claim 13, wherein said clamp is provided with lift springs which act when said bar pressure is relieved to retract said clamp.
