Abstract
Abstract A film splicer in which the two ends of the film to be spliced are held in clips and pivoted between a cutting block and a taping block, the splicer including a roll of tape mounted between the two blocks designed to be pulled out into contact with the film so as to join the two ends together and further including a combination hole punch and knife pivotable above the film so as to cut off the excess tape and form new sprocket holes in the film.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A film splicer comprising in combination: a base having a cutting surface and a splicing surface thereon; film holding means on said base between said cutting surface and said splicing surface, and pivotable about an axis running generally along said surface so as to be operable to carry the ends of two pieces of film in abutting relationship into position on the cutting surface and the splicing surface, said film holding means comprising a pair of proximate spring members extending up from the pivot axis in two branches, one for each of said two pieces of film; tape supply means on the base adapted to permit tape to be applied to the ends of the film on the splicing surface; a first cutting means on said base operable to make congruent cuts in the ends of said two pieces of film when said film is on said cutting surface; and a second cutting means mounted on said base operable to cut off excess tape when said film is on the splicing surface.
Claim 2
Dependent Claim
172 words
A film splicer comprising in combination: a base having a cutting surface and a splicing surface thereon; film holding means on said base between said cutting surface and said splicing surface, and pivotable about an axis running generally along said surface so as to be operable to carry the ends of two pieces of film in abutting relationship into position on the cutting surface and the splicing surface, said film holding means comprising a pair of proximate spring members extending up from the pivot axis in two branches, one for each of said two pieces of film; tape supply means on the base adapted to permit tape to be applied to the ends of the film on the splicing surface; a first cutting means on said base operable to make congruent cuts in the ends of said two pieces of film when said film is on said cutting surface; and a second cutting means mounted on said base operable to cut off excess tape when said film is on the splicing surface.
Claim 3
Dependent Claim
35 words
The apparatus of claim 1 in which said second cutting means includes also a sprocket hole punching means operable to punch new sprocket holes in the film when said film is on the splicing surface.
Claim 4
Dependent Claim
44 words
The apparatus of claim 2 in which said second cutting means comprises a guide block assembly for holding and guiding a cutting blade and sprocket hole punching pins against the action of a spring toward and away from the film on the splicing surface.
Claim 5
Dependent Claim
29 words
The apparatus of claim 3 in which said guide block assembly is mounted on a pivot arm pivoted on said base, said arm also supporting said first cutting means.
Claim 6
Dependent Claim
32 words
