Abstract
Abstract Apparatus for trimming and assembling separate parts of a document such as a plan or map, including a shallow box-like container having a supporting surface on which the parts may be placed, the surface having a slit therein adapted to accept a cutting implement. A pair of clamping members are each pivotally mounted on the container so as to be pivotable between a raised position and a clamping position on the surface adjacent a respective side of the slit, each clamping member having associated therewith a set of electro-magnets which, when energized, attract the associated clamping member so that parts of a document are held against undesired movement. The cutting implement is secured to a carriage slidably mounted on one of the clamping members so that the implement is movable to and fro along the slit.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
Apparatus for trimming and assembling parts of a document, comprising: a support member having a surface on which said parts are positioned, said surface having a slit therein to accept a cutting implement; magnetic means mounted on said support; and a pair of clamping members each movable to an operative position adjacent said surface, each on a respective side of said slit; said magnetic means attracting said clamping members when said parts of a document are positioned on said surface between said surface and said clamping members; whereby said parts are held against undesired movement; a carriage slidably mounted on one of said clamping members, said carriage carrying a cutting implement which is urged into engagement with said slit against a resilient bias; means sliding said cutting implement longitudinally along the length of said slit to cut said parts of a document overlying the slit so that the severed peripheral area of said document parts may be removed, leaving the two parts in abutting relationship along a line along a line on which said parts are to be joined.
Claim 2
Dependent Claim
179 words
Apparatus for trimming and assembling parts of a document, comprising: a support member having a surface on which said parts are positioned, said surface having a slit therein to accept a cutting implement; magnetic means mounted on said support; and a pair of clamping members each movable to an operative position adjacent said surface, each on a respective side of said slit; said magnetic means attracting said clamping members when said parts of a document are positioned on said surface between said surface and said clamping members; whereby said parts are held against undesired movement; a carriage slidably mounted on one of said clamping members, said carriage carrying a cutting implement which is urged into engagement with said slit against a resilient bias; means sliding said cutting implement longitudinally along the length of said slit to cut said parts of a document overlying the slit so that the severed peripheral area of said document parts may be removed, leaving the two parts in abutting relationship along a line along a line on which said parts are to be joined.
Claim 3
Dependent Claim
24 words
Apparatus as claimed in claim 1, wherein said magnetic means comprises two sets of electro-magnets positioned one set on each side of said slit.
Claim 4
Dependent Claim
20 words
Apparatus as claimed in claim 2 in which each set comprises four electro-magnets spaced along the length of the slit.
Claim 5
Dependent Claim
28 words
An apparatus according to claim 1 further comprising means to pivot said pair of clamping members between said operative position and an inoperative position clear of said surface.
Claim 6
Dependent Claim
31 words
Apparatus as claimed in claim 2, wherein each clamping member carries a soft iron element which is aligned with an associated electromagnet when said clamping member is in the operative position.
