Abstract
A phonograph record holder comprising a substantially dust-proof flat, circular case including separable sections each adapted to carry a group of stacked records, locking means operable to secure the records in each case section when that section is removed from the other with its own side down, to facilitate handling of the record stacks when placing them on or removing them from the spindles of automatic record changers, and spring presser members operable to maintain the stacks under compressive pressure to inhibit warpage of the records.
Claims7
A phonograph record holder comprising:
- a. a circular case divided normally to its axis into two sections each of which has an open end normally confronting the other section, and being closed at its opposite end to form a base, each of said sections being adapted to carry one or more disc-type phonograph records therein normally to its axis,
- b. connecting means operable to secure the open ends of said case sections in interengaging relation to close said case, with the records contained in each section confined to their respective sections, said connecting means being adjustable to secure said sections together at varying degrees of axial interengagement, whereby to compensate for variable numbers of records carried in each of the case sections, and
- c. loading means carried within the case and operable, as said case sections are moved coaxially into interengagement to close said case, to exert an axial load on the record or stack of records carried in each case section, whereby to secure said records against movement relative to each other, or relative to said case.
A phonograph record holder comprising:
- a. a circular case divided normally to its axis into two sections each of which has an open end normally confronting the other section, and being closed at its opposite end to form a base, each of said sections being adapted to carry one or more disc-type phonograph records therein normally to its axis,
- b. connecting means operable to secure the open ends of said case sections together to close said case, with the record or records carried by each case section confined to that section, and
- c. retainer means operable to secure the record or records carried in each of said case sections against removal therefrom through the open end thereof whenever said open end is facing downwardly whereby regardless of which section may be uppermost at any given time, said uppermost section may be detached and removed from the other section without spillage of records from the former, said retainer means comprising a spacer member disposed between those records carried by one of said case sections and those carried by the other section, a first gravity-actuated lock carried by one of said case sections, and a second gravity-actuated lock carried by the other of said case sections, each of said locks being adapted to secure said spacer member to the associated case section to secure any records carried therebetween in said case section whenever said case section is in position to open downwardly, and to release said spacer whenever said case section is positioned to open upwardly.
