Claim 1
Independent Claim

A center spindle for a record-changing phonograph, comprising a sleeve having a plurality of axially directed slots disposed in two groups at different heights, primary control means provided in said sleeve and operable by an axial movement thereof, a plurality of primary record-supporting members, each placed in one of said slots of an upper of said groups and coupled with said primary control means such, that said primary recordsupporting members are movable into a position outside of the outer periphery of said sleeve by axial movement, secondary control means in said sleeve and operable by an axial movement thereof, a plurality of secondary record-supporting members comprising obliquely upwardly arranged stays and each placed in one of said slots of the lower of said groups, the upper end of said secondary record-supporting members being disposed at a distance, below the lower end of said primary record-supporting members, corresponding with about the thickness of one record, said secondary record-supporting members being rotatably connected with said secondary control means in an axial plane of said center spindle, a control edge fixed on said sleeve, swinging back said secondary record-supporting members from one rotary position outside of the outer periphery of said sleeve into said sleeve by said axial movement, spring means resiliently retaining said secondary supporting members in a primary, median rotary position supporting said records, such that the weight of at least one record exerted upon said secondary record-supporting members swings the latter against the force of said spring means into a secondary rotary position of greater spread, an abutment means provided on said sleeve within the range of the axial movement of at least one of said secondary recordsupporting members, and said at least one of said secondary record-supporting members having an extension at its lower end such, that it moves duRing an axial downward movement of said one of said secondary record-supporting members towards said abutment means, thereby stopping the normal axial movement of said at least one secondary record-supporting member and locking a further movement of said secondary control means, when said secondary record-supporting members are disposed in said primary, median rotary position, and said at least one of said secondary record-supporting members pass freely said abutment means, upon moving into said secondary rotary position.

A center spindle for a record-changing phonograph, comprising a sleeve having a plurality of axially directed slots disposed in two groups at different heights, primary control means provided in said sleeve and operable by an axial movement thereof, a plurality of primary record-supporting members, each placed in one of said slots of an upper of said groups and coupled with said primary control means such, that said primary recordsupporting members are movable into a position outside of the outer periphery of said sleeve by axial movement, secondary control means in said sleeve and operable by an axial movement thereof, a plurality of secondary record-supporting members comprising obliquely upwardly arranged stays and each placed in one of said slots of the lower of said groups, the upper end of said secondary record-supporting members being disposed at a distance, below the lower end of said primary record-supporting members, corresponding with about the thickness of one record, said secondary record-supporting members being rotatably connected with said secondary control means in an axial plane of said center spindle, a control edge fixed on said sleeve, swinging back said secondary record-supporting members from one rotary position outside of the outer periphery of said sleeve into said sleeve by said axial movement, spring means resiliently retaining said secondary supporting members in a primary, median rotary position supporting said records, such that the weight of at least one record exerted upon said secondary record-supporting members swings the latter against the force of said spring means into a secondary rotary position of greater spread, an abutment means provided on said sleeve within the range of the axial movement of at least one of said secondary recordsupporting members, and said at least one of said secondary record-supporting members having an extension at its lower end such, that it moves duRing an axial downward movement of said one of said secondary record-supporting members towards said abutment means, thereby stopping the normal axial movement of said at least one secondary record-supporting member and locking a further movement of said secondary control means, when said secondary record-supporting members are disposed in said primary, median rotary position, and said at least one of said secondary record-supporting members pass freely said abutment means, upon moving into said secondary rotary position.
Claim 3
Dependent Claim
35 words
The center spindle, as set forth in claim 1, wherein said primary control means includes spring means engaging said sleeve, at one end, in order to retain said primary control means in its lower position.
Claim 4
Dependent Claim
25 words
The center spindle, as set forth in claim 1, wherein said secondary control means is axially displaceable in said sleeve below said primary control means.
Claim 5
Dependent Claim
70 words
The center spindle, as set forth in claim 1, wherein said primary control means and said secondary control means are disposed at such distance relative to each other, that upon lifting said secondary control means from its lower position said secondary record-supporting members swing at first outwardly from the periphery of said sleeve, to join thereafter, during the remaining upward movement of said secondary control means, said primary control means.
