US Patent:

39998185, Dec 28, 1976

Filed:

Jun 20, 1975

Appl. No.:

5/588693

Inventors:

Martin M. Schankler - East Brunswick NJ

Assignee:

Microfilm Enterprises Corporation - East Brunswick NJ

International Classification:

F16B 1200
A47B 8700

US Classification:

312111

Abstract:

An interlocking system of identical modules for storage of microfilm cartridges or boxes. The module is capable of being formed as a unitary member in a relatively inexpensive mold. The module has top, bottom, left side, right side and rear walls, and an open front. The top and bottom of the module have corresponding exterior projections and recesses of dovetail cross-section, and the left and right side walls also have dovetail projections and recesses on the exterior surfaces thereof which correspond with one another. The top of one module may be interlocked with the bottom of another module by engaging the adjacent projection and recess thereof. Similarly, a side wall of one module may be interlocked with the opposite side wall of another module. The rear surface of each module contains an arrangement of dovetail projections which is capable of interlocking with the left or right side wall of another module, thus permitting modules to be interlocked to form three dimensional arrays particularly suitable for use in carousel arrangements.

International Classification:

B65H 1702

US Classification:

242 685

Abstract:

A spacer for use on microfilm reels to facilitate the storage of relatively small lengths of film thereon. The spacer comprises a unitary structure of resilient material having adjacent separable arcuate end portions which are deflected when the spacer is pressed onto the hub of the film reel, the resilience of the spacer material causing the arcuate end portions to come together when the spacer is on the reel hub. A plurality of spacing bars extend from the circular outer configuration of the spacer to define an inner circle having a diameter substantially equal to the outer diameter of the reel hub. The film to be stored may be threaded onto the reel hub between the arcuate end portions of the spacer.

Abstract:

The disclosure relates to an improved core for holding web material. The core includes a cylinder having an axis of rotation and an axially extending slot for receiving the web material, a rectangular collar within the cylinder to form an annular channel and an annular channel floor between the cylinder and the column to maintain a substantially concentric relation there between. The core also includes first, second and third tapered rib members for positioning the web material within the annular channel and a channeled wall member mounted on the rectangular collar opposite a tapered rib member; a post is included within the annular channel in combination with a fourth tapered rib member adjacent thereto. A labyrinth of web material formed by threading an end of the web through the slot into the annular channel along the outer peripheral surface of the rectangular collar, adjacent a first tapered rib member, between a second tapered rib and the channel wall member, adjacent a third tapered rib around the post and adjacent the fourth tapered rib member winding back through the channel and out the slot. The cooperative action of the restraining effect of the post and adjacent wall on the web material, the extended frictional contact between the resulting two layers of web material and the frictional engagement of the web material about the outer peripheral surface of the rectangular collar securely restrain the web to the core during both winding and unwinding operations.
