Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
222 words
A device for cutting transparencies from a filmstrip including a base frame assembly, a top plate mounted on said base frame assembly, a guideway in said top plate for the filmstrip, a cutter knife and anvil plate mounted on said top plate at the discharging end of said guideway, a transparency mount rest secured on said base frame assembly and positioned below and beyond the discharging end of said guideway reciprocating filmadvancing means mounted in said base frame assembly, film edge gripping elements in said film-advancing means, said guideway formed with a longitudinally extended slot to accommodate said gripping elements, said gripping elements extending up into said slot for movement along therein, means in said film-advancing means causing said elements to grip the film upon each forward stroke of said advancing means and to release the grip upon the return stroke, means for automatically producing a reciprocating stroke of said advancing means with each operation of the device, means automatically causing operation of said cutter knife when said advancing means reaches the forward end of its travel, and means for adjusting the travel of said film advancing means and therewith of said film-gripping elements whereby to adjust the extent to which the filmstrip is advanced and the length of the section cut off from the filmstrip with each operation of the device.
Claim 2
Independent Claim
222 words
A device for cutting transparencies from a filmstrip including a base frame assembly, a top plate mounted on said base frame assembly, a guideway in said top plate for the filmstrip, a cutter knife and anvil plate mounted on said top plate at the discharging end of said guideway, a transparency mount rest secured on said base frame assembly and positioned below and beyond the discharging end of said guideway reciprocating filmadvancing means mounted in said base frame assembly, film edge gripping elements in said film-advancing means, said guideway formed with a longitudinally extended slot to accommodate said gripping elements, said gripping elements extending up into said slot for movement along therein, means in said film-advancing means causing said elements to grip the film upon each forward stroke of said advancing means and to release the grip upon the return stroke, means for automatically producing a reciprocating stroke of said advancing means with each operation of the device, means automatically causing operation of said cutter knife when said advancing means reaches the forward end of its travel, and means for adjusting the travel of said film advancing means and therewith of said film-gripping elements whereby to adjust the extent to which the filmstrip is advanced and the length of the section cut off from the filmstrip with each operation of the device.
Claim 3
Dependent Claim
32 words
The device of claim 1 with said means for adjusting the travel of said reciprocating film-advancing means consisting of an adjustable stop restricting the rear return stroke of said reciprocating film-advancing means.
Claim 4
Dependent Claim
125 words
The device of claim 1 with the addition of an illuminated window in the bottom of said guideway, and a substantially transparent indicator spaced above said window having suitable marking thereon to enable the relative positioning of the division lines between consecutive transparencies in the filmstrip beneath said indicator with respect to said indicator marking to serve as a guide in adjusting the travel of said film-advancing means. 4 The device of claim 1 with said top plate shiftably mounted on said base frame assembly to enable the discharging end of said guideway and therewith the position of the cutoff transparency discharged from said guideway to be adjusted relatively with respect to the inside dimensiOns of the corresponding transparency mount positioned on said mount rest.
Claim 5
Dependent Claim
28 words
The device as set forth in claim 4 with the addition of means for guiding and restricting the shifting of said top plate on said base frame assembly.
