Abstract

Abstract The specification describes a device for supporting phonograph records on the step of a long turntable spindle of an automatic record player, and for sequentially causing individual records to fall on said turntable for playing. The device comprise a long oscillatable arm located within said spindle, having an upper notched tip adapted to shifting the lowermost record in a stack located on said step, and desengaging it from said step, and a lower end portion cooperatively engaged in a control lever cooperating with the record layer program selection lever for phasedly oscillating said arm. The device is complemented with a separate body, designed for slidably fit on the upper portion of the spindle, over the record stack and designed for maintaining said stack horizontal and for latching said notched tip in its oscillated position when the last record of the stack has been caused to fall, for modifying the record player program. An ancillary member for adapting the device to manipulate large holed 45 r.p.m. records.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 292 words
A device for sequentially and phasedly promoting the dropping and the positioning of phonograph records on the turntable of an automatic record player apparatus of the type comprising a long turntable spindle having at its upper portion a step for supporting a stack of records at a level above said turntable, and a mechanism including a selection lever swingable from one another of two positions at which the record player is set to automatically stop when the playing of one record has been completed (''''program (i)'''') and respectively for automatic sequential playing of records (''''program (ii)''''), wherein the said long spindle has an elongated arm longitudinally and oscillatably supported thereinto, said arm having a notched upper tip projecting above the step and positioned for sliding off and desengaging from said step the lowermost record in saId stack when oscillated in a given direction and a lower tip engaging a swingable control lever cooperatively associated to said selection lever, means for swinging said control lever in phase with the return motion of the tone-arm of the record player and oscillating said arm in said given direction, and concurrently causing said selection lever to set for ''''program (i)'''', spring return means for returning said levers and arm as a record of the stack has been caused to drop on the turntable, and a stack levelling separate component adapted for being vertically slidably fitted about said spindle above said stack and having a notched lower portion complementary to said notched upper tip of the said elongated arm to latch said arm as oscillated in said given direction in absence of any record on said step for maintaining said setting for ''''program (i)'''' when the last record of the stack has been dropped on the turntable.
Claim 2
Independent Claim 292 words
A device for sequentially and phasedly promoting the dropping and the positioning of phonograph records on the turntable of an automatic record player apparatus of the type comprising a long turntable spindle having at its upper portion a step for supporting a stack of records at a level above said turntable, and a mechanism including a selection lever swingable from one another of two positions at which the record player is set to automatically stop when the playing of one record has been completed (''''program (i)'''') and respectively for automatic sequential playing of records (''''program (ii)''''), wherein the said long spindle has an elongated arm longitudinally and oscillatably supported thereinto, said arm having a notched upper tip projecting above the step and positioned for sliding off and desengaging from said step the lowermost record in saId stack when oscillated in a given direction and a lower tip engaging a swingable control lever cooperatively associated to said selection lever, means for swinging said control lever in phase with the return motion of the tone-arm of the record player and oscillating said arm in said given direction, and concurrently causing said selection lever to set for ''''program (i)'''', spring return means for returning said levers and arm as a record of the stack has been caused to drop on the turntable, and a stack levelling separate component adapted for being vertically slidably fitted about said spindle above said stack and having a notched lower portion complementary to said notched upper tip of the said elongated arm to latch said arm as oscillated in said given direction in absence of any record on said step for maintaining said setting for ''''program (i)'''' when the last record of the stack has been dropped on the turntable.
Claim 3
Dependent Claim 107 words
The device of claim 1, comprising further an ancillary equipment consisting of a body bored for slidably fitting about said long spindle and including an upper portion positioned laterally of the upper portion of said spindle to form jointly with said portion a guide means for positioning a stack of 45 r.p.m. records having a 38 millimeters diameter center hole on said step, a lower portion symmetrical to said spindle for centering such records on the turntable, and a middle portion having parallel slanting side surfaces for guiding records desengaged from said step from an off-set position on said step to a centered position on said turntable.
Claim 4
Dependent Claim 62 words
The device of claim 1, wherein the said separate component consists of a relatively heavy flat cylindrical body centrally bored for slidably fitting about the upper portion of said spindle and having a ring-shaped downward projection about the lower outlet of the bore, said projection being complemental of the upper notched tip of said elongated lever when oscillated in said given direction.
Claim 5
Dependent Claim 81 words
The device of claim 1, wherein the said swingable control lever comprises an arm portion located below the said long spindle, a hole in said arm portion for oscillatable engagement of the lower end portion of said elongated arm, and an slanting surface adjacent to said hole, said surface being inclined for causing swinging of said lever when said lower end portion is downwardly urged on said surface until alignment with and engagement of said lower end portion in said hole.
Claim 6
Dependent Claim 222 words
The device of claim 4, wherein the said swingable control lever has a pin secured thereto in a position spaced from the pivotal axis of said lever, and the said selection lever has a recessed edge portion positioned to abut on said pin in either of three locations of the flanks of the recess to position said selection lever for ''''program (i)'''' when the abutment occurs at any of a first and of a third location and respectively for ''''program (ii)'''' when at the second location, wherein spring means are connected to selection lever for biasing same in abutment of its recess on said pin, wherein further spring means are connected to said control lever for biasing same towards a position in which said abutment occurs in said first location, wherein the engagement of said elongated arm with said control lever causes the same to occupy a second position in which said abutment occurs in said second location, and wherein a tone-arm controlled component has means to engage said control lever upon completion of the return motion of said tone-arm and to swing said control lever in a third position wherein said abutment occurs in said third location and the said elongated arm is oscillated for shifting a record off from the step and causing said record to drop on the turntable.
