Abstract
Abstract A film cutter and splicer for cutting various sizes and types of motion picture film such as 35, 16 and 8mm. It consists of a base to which any one of a number of different blocks may be secured, each block being adapted to receive a different size film. Thus to cut different film it is only necessary to change the blocks, the same basic cutting mechanism being used for all size films. A hold-down plate is also provided so that the device may also be conveniently employed to apply adhesive splicing tape to the film.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
142 words
A film cutter for use in cutting motion picture film comprising: a base; a stationary shear secured to said base; a movable shear movably mounted on said base and cooperable with said stationary shear to shear a film positioned theRebetween; a plurality of film support blocks having a surface for supporting a strip of film during shearing, each being adapted to accommodate a different style of film; and each being readily mountable and demountable from said base; whereby any one of a number of different types of film may be sheared simply by mounting the appropriate block on said base; recess means in said block for receiving said stationary shear; mounting means for mounting said block to said base with said stationary shear residing in said recess means, and with a cutting edge of said stationary shear substantially flush with said surface.
Claim 2
Dependent Claim
142 words
A film cutter for use in cutting motion picture film comprising: a base; a stationary shear secured to said base; a movable shear movably mounted on said base and cooperable with said stationary shear to shear a film positioned theRebetween; a plurality of film support blocks having a surface for supporting a strip of film during shearing, each being adapted to accommodate a different style of film; and each being readily mountable and demountable from said base; whereby any one of a number of different types of film may be sheared simply by mounting the appropriate block on said base; recess means in said block for receiving said stationary shear; mounting means for mounting said block to said base with said stationary shear residing in said recess means, and with a cutting edge of said stationary shear substantially flush with said surface.
Claim 3
Dependent Claim
143 words
A film cutter for use in cutting motion picture film comprising: a base; a stationary shear secured to said base; a movable shear movably mounted on said base and cooperable with said stationary shear to shear a film positioned therebetween; a film support block having a surface for supporting a strip of film during shearing; recess means in said block for receiving said stationary shear; an anvil in said recess means in position to be engaged by said movable shear as a film is sheared; means for resiliently mounting said anvil for limited movement when engaged by said movable shear; a face of said anvil being substantially flush with said surface; mounting means for mounting said block to said base with said stationary shear residing in said recess means, and with a cutting edge of said stationary shear substantially flush with said surface.
Claim 4
Dependent Claim
143 words
A film cutter for use in cutting motion picture film comprising: a base; a stationary shear secured to said base; a movable shear movably mounted on said base and cooperable with said stationary shear to shear a film positioned therebetween; a film support block having a surface for supporting a strip of film during shearing; recess means in said block for receiving said stationary shear; an anvil in said recess means in position to be engaged by said movable shear as a film is sheared; means for resiliently mounting said anvil for limited movement when engaged by said movable shear; a face of said anvil being substantially flush with said surface; mounting means for mounting said block to said base with said stationary shear residing in said recess means, and with a cutting edge of said stationary shear substantially flush with said surface.
Claim 5
Dependent Claim
143 words
A film cutter for use in cutting motion picture film comprising: a base having a block receiving ledge; a stationary shear projecting transversely over said ledge secured to said base; a movable shear movably mounted on said base and cooperable with said stationary shear to shear a film positioned therebetween, said movable shear movable in a plane transverse to said ledge; a film support block having a surface for supporting a strip of film during shearing, said block being elongate and residing on said ledge; recess means in said block for receiving said stationary shear, said recess means comprising a transverse slot in said block into which said stationary shear extends; mounting means for mounting said block to said base with said stationary shear residing in said recess means, and with a cutting edge of said stationary shear substantially flush with said surface.
Claim 6
Dependent Claim
143 words
A film cutter for use in cutting motion picture film comprising: a base having a block receiving ledge; a stationary shear projecting transversely over said ledge secured to said base; a movable shear movably mounted on said base and cooperable with said stationary shear to shear a film positioned therebetween, said movable shear movable in a plane transverse to said ledge; a film support block having a surface for supporting a strip of film during shearing, said block being elongate and residing on said ledge; recess means in said block for receiving said stationary shear, said recess means comprising a transverse slot in said block into which said stationary shear extends; mounting means for mounting said block to said base with said stationary shear residing in said recess means, and with a cutting edge of said stationary shear substantially flush with said surface.
Claim 7
Dependent Claim
41 words
Cutter in accordance with claim 3, including: an anvil bar in said slot flush with said surface, and engageable by said movable shear; means for resiliently mounting said bar to resiliently give way as it is engaged by said movable shear.
Claim 8
Dependent Claim
89 words
A film cutter for use in cutting motion picture film, comprising: a base; a cutting blade movably mounted on said base; a series of film-supporting blocks selectively mountable on said base, each block having positioning pins for positioning a strip of motion picture film on the block in position to be cut by said blade, the pins of the several blocks being different in character so that each block may selectively accommodate a different style of motion picture film; means for detachably securing a given block to said base.
Claim 9
Dependent Claim
89 words
A film cutter for use in cutting motion picture film, comprising: a base; a cutting blade movably mounted on said base; a series of film-supporting blocks selectively mountable on said base, each block having positioning pins for positioning a strip of motion picture film on the block in position to be cut by said blade, the pins of the several blocks being different in character so that each block may selectively accommodate a different style of motion picture film; means for detachably securing a given block to said base.
Claim 10
Dependent Claim
24 words
A cutter in accordance with claim 5 wherein: said base is formed with a shelf onto which a given block is mounted when installed.
