Claim 1
Independent Claim
397 words
A microfilm-jacket-notching device comprising in combination: a support structure defining a recess downwardly therein and defining seat spaces on each of opposite lateral sides of the recess for the seating of opposite ends of an axis structure and defining along an upper face of the structure shoulder structure on each of opposite edges extending from front to back along lateral sides of the recess thereby shaping a front-to-back slot between the opposite shoulder structures; a blade means including a wheel-like structure and an axis therefor seatable in each of the seat spaces at each of opposite ends of the axis respectively, the wheel-like structure defining a substantially linear face in substantially parallel alignment with the axis and extending linearly from side to side of the wheel-like structure, and the face extending angularly in each of opposite direction substantially circumscribing the wheel-like structure, and further defining each of opposite sidewalls diverging outwardly laterally from the opposite-end sidewall of the wheel-like structure as the respective sidewalls extend radially inwardly, and further defining a first face-recess in said face extending back radially inwardly into each of said opposite diverging sides and the structure defining an upper edge of the first face-recess extending at an angle across said face to form thereby a blade having a point at the lower end of the angled upper edge, and the wheel-like structure defining an abutting member for abutting an abutment limiting upward pivotal movement of the blade around the axis; a plate structure defining a central space therethrough having a size and shape shaped to substantially flushly receive the wheel-like structure with a predetermined excess space on at least the forward edge thereof adjacent the blade and opposite diverging sides adjacent the blade such that the plate may be shifted slidably to and fro from forward and rearward directions within said slot, the forward edge of the plate''s central-space structure being substantially parallel with the face at points in juxtaposition therewith such that a scissor cutting action results between the upper front edge of the plate and the blade when the blade is brought downwardly relative to the plates forward front edge upon revolving pivotably the wheel-like structure; and spring means biased against said plate and supported such that the plate is spring-biased rearwardly along the slot in a sliding position between the shoulders thereby providing for a snug and clean-cutting blade action.

A microfilm-jacket-notching device comprising in combination: a support structure defining a recess downwardly therein and defining seat spaces on each of opposite lateral sides of the recess for the seating of opposite ends of an axis structure and defining along an upper face of the structure shoulder structure on each of opposite edges extending from front to back along lateral sides of the recess thereby shaping a front-to-back slot between the opposite shoulder structures; a blade means including a wheel-like structure and an axis therefor seatable in each of the seat spaces at each of opposite ends of the axis respectively, the wheel-like structure defining a substantially linear face in substantially parallel alignment with the axis and extending linearly from side to side of the wheel-like structure, and the face extending angularly in each of opposite direction substantially circumscribing the wheel-like structure, and further defining each of opposite sidewalls diverging outwardly laterally from the opposite-end sidewall of the wheel-like structure as the respective sidewalls extend radially inwardly, and further defining a first face-recess in said face extending back radially inwardly into each of said opposite diverging sides and the structure defining an upper edge of the first face-recess extending at an angle across said face to form thereby a blade having a point at the lower end of the angled upper edge, and the wheel-like structure defining an abutting member for abutting an abutment limiting upward pivotal movement of the blade around the axis; a plate structure defining a central space therethrough having a size and shape shaped to substantially flushly receive the wheel-like structure with a predetermined excess space on at least the forward edge thereof adjacent the blade and opposite diverging sides adjacent the blade such that the plate may be shifted slidably to and fro from forward and rearward directions within said slot, the forward edge of the plate''s central-space structure being substantially parallel with the face at points in juxtaposition therewith such that a scissor cutting action results between the upper front edge of the plate and the blade when the blade is brought downwardly relative to the plates forward front edge upon revolving pivotably the wheel-like structure; and spring means biased against said plate and supported such that the plate is spring-biased rearwardly along the slot in a sliding position between the shoulders thereby providing for a snug and clean-cutting blade action.
Claim 3
Dependent Claim
19 words
A microfilm jacket-notching device of claim 1, including handle means for rotating pivotably the wheel-like structure around the axis.
Claim 4
Dependent Claim
122 words
A microfilm jacket-notching device of claim 2, including linear aligning structure extending substantially parallel to the axis forwardly of the axis and above the plate structure''s upper surface and above the slot, spaced from the axis a distance less than the wheel structure''s radius and extending as shoulders one in each of opposite direcTions from points in juxtaposition to each of opposite radially inwardly diverging sides such that a flat microfilm having a linear edge when aligned along either or both of the shoulders extends through the face-recess between the blade and the forward edge of the plate''s central-space structure whereby rotation of the wheel-like structure to move the blade downwardly cuts a notch from the edge of the micro-film''s linear edge.
Claim 5
Dependent Claim
86 words
A microfilm jacket-notching device of claim 3, including a gauging means movably mounted on said support structure, movable laterally to and fro in a line of movement extending in front of said blade and in front of said aligning shoulders and including indicator means indicative of different positions along the aligning shoulders for positioning a microfilm rectangular or squared jacket for effecting the predetermined positioning of a notch to be cut by the blade from the edge of the microfilm jacket aligned along the aligning shoulders.
Claim 6
Dependent Claim
100 words
A microfilm jacket-notching device of claim 4, in which the gauging means includes a snap-in key element and a spring biasing the key into releasable locking states and the gauging means further includes a slide structure having a flat upper face and slidably mounted on the support structure and including structure coordinately defined in the support structure and the slide structure defining a series of consecutive key-receiving positions and the spring spring-biasing the key into the positions as the plate structure is slid to one or another of the different predetermined positions for notching an edge of a microfilm jacket.
Claim 7
Dependent Claim
97 words
A microfilm jacket-notching device of claim 5, in which the rearward face of the wheel-like structure includes an indentation, and the spring means is biased against the abutting member such that the plate structure is biased rearwardly, and the plate structure including a rearward edge extending about horizontally through the wheel-like structure''s rearward-face indentation such that as the blade is biased upwardly by action of the spring means against the abutting member, upward movement of the blade is terminated by abutment of the abutting member against an upper surface of the rearward edge of the plate structure.
Claim 8
Dependent Claim
97 words
A microfilm jacket-notching device of claim 1, in which the rearward face of the wheel-like structure includes an indentation, and the spring means is biased against the abutting member such that the plate structure is biased rearwardly, and the plate structure including a rearward edge extending about horizontally through the wheel-like structure''s rearward-face indentation such that as the blade is biased upwardly by action of the spring means against the abutting member, upward movement of the blade is terminated by abutment of the abutting member against an upper surface of the rearward edge of the plate structure.
