Claim 3

A cassette according to claim 1 and a. an aperture in the housing over the storage chamber dimensioned to permit the insertion of a film into the storage chamber, b. a cover for the aperture engageable and disengageable with the housing.

Claim 4

A cassette according to claim 1 and a means to hold the end of a film at the film withdrawal port.

Claim 5

A cassette according to claim 3 in which the means to hold the end of a film at the film withdrawal port comprises a. a notch on the housing defining a seat for a pin attached to the end of a film which extends out of the withdrawal port, b. a spring attached to the housing, encroaching on the notch, and normally urging a pin into seated engagement with the notch.

Claim 6

A cassette according to claim 1 and a. a transverse wall in the housing between the storage chamber and the projection chamber, b. a slit in the wall in general registration with a plane defined by the path of a film extending linearly from between the pair of film guides in the storage chamber to the pair of film guides in the projection chamber.

Claim 7

A cassette according to claim 3 and a. a spool of film in the storage chamber, b. the end of the film passed through both pairs of film guides and out through the film withdrawal port, c. a pin attached to the end of the film, d. the pin engaged with the means to hold the end of the film.

Claim 8

A cassette according to claim 4 and a. a spool of film in the storage chamber, b. the end of the film passed through both pairs of film guides and out through the film withdrawal port, c. a pin attached to the end of the film, and seated in the notch and engaged by the spring.

Claim 9

A cassette for film according to claim 1 and enlargments at the bottom of the housing for positioning the cassette with the film therein disposed for projection.

Claim 10

A cassette for film comprising a. a housing having a generally, longitudinally tapered construction to enable maximum radial disposition of cassettes in a random access apparatus, b. a storage chamber for a spool of film at the wider end of the tapered housing, c. a means for rotatably supporting a spool of film in the storage chamber, d. a pair of film guides in the storage chambers for guiding film away from a spool in the storage chamber, e. a projection chamber for film adjacent to the storage chamber, at the narrower end of the housing, f. a pair of film guides in the projection chamber adjacent to the end thereof, g. side apertures in projection chamber for a beam of light to pass through the chamber and through a film extending between both pairs of film guides, h. an access port in the top of housing at the projection chamber, positioned between the pairs of guides, and extending on both sides of the course defined by a film extending between both pairs of guides, for allowing the vertical entry into the projection chamber of a means to maneuver a film, i. a film withdrawal port in the projection chamber for the end of the film to be engaged for movement of the film through the projection chamber and out of the housing until a preselected portion of the film is in registration with the side apertures for projection, j. a port in the housing for the entry of a key into the storage chamber to rewind a film, k. an aperture in the housing over the storage chamber dimensioned to permit the insertion of a film into the storage chamber, l. a cover for the aperture engageable and disengageable with the housing, m. a notch on the housing defining a seat for a pin attached to the end of a film which extends out of the withdrawal port, n. a spring attached to the housing, encroaching on the notch, and normally urging a pin into seated engagement with the notch, o. a transverse wall in the housing between the storage chamber and the projection chamber, p. a slit in the wall in general registration with a plane defined by the path of a film extending linearly from between the pair of film guides in the storage chamber to the pair of film guides in the projection chamber, q. a spool of film in the storage chamber, r. the end of the film passed through both pairs of film guides and out through the film withdrawal port, s. a pin attached to the end of the film, and seated in the notch and engaged by the spring, t. enlargements at the bottom of the housing for positioning the cassette with the film therein disposed for projection.

Claim 11

A cassette for film comprising a. a housing having a generally, longitudinally tapered construction to enable maximum radial disposition of cassettes in a random access apparatus, b. a storage chamber for a spool of film at the wider end of the tapered housing, c. a means for rotatably supporting a spool of film in the storage chamber, d. a pair of film guides in the storage chambers for guiding film away from a spool in the storage chamber, e. a projection chamber for film adjacent to the storage chamber, at the narrower end of the housing, f. a pair of film guides in the projection chamber adjacent to the end thereof, g. side apertures in projection chamber for a beam of light to pass through the chamber and through a film extending between both pairs of film guides, h. an access port in the top of housing at the projection chamber, positioned between the pairs of guides, and extending on both sides of the course defined by a film extending between both pairs of guides, for allowing the vertical entry into the projection chamber of a means to maneuver a film, i. a film withdrawal port in the projection chamber for the end of the film to be engaged for movement of the film through the projection chamber and out of the housing until a preselected portion of the film is in registration with the side apertures for projection, j. a port in the housing for the entry of a key into the storage chamber to rewind a film, k. an aperture in the housing over the storage chamber dimensioned to permit the insertion of a film into the storage chamber, l. a cover for the aperture engageable and disengageable with the housing, m. a notch on the housing defining a seat for a pin attached to the end of a film which extends out of the withdrawal port, n. a spring attached to the housing, encroaching on the notch, and normally urging a pin into seated engagement with the notch, o. a transverse wall in the housing between the storage chamber and the projection chamber, p. a slit in the wall in general registration with a plane defined by the path of a film extending linearly from between the pair of film guides in the storage chamber to the pair of film guides in the projection chamber, q. a spool of film in the storage chamber, r. the end of the film passed through both pairs of film guides and out through the film withdrawal port, s. a pin attached to the end of the film, and seated in the notch and engaged by the spring, t. enlargements at the bottom of the housing for positioning the cassette with the film therein disposed for projection.
