Abstract

Abstract A motorized toy phonograph assembly having a housing comprising in combination; a speaker cone subassembly in which a speaker cone is mounted, a motor subassembly in which a DC motor is mounted and a turntable subassembly in which a turntable is mounted with a phonograph record thereon, an intermediate wall separating the speaker cone subassembly from the turntable subassembly and having a predetermined opening for a tonearm pivotally connected to the housing in a biased position between the phonograph record and the speaker cone. The turntable is secured to a fixed shaft movable within a slot in the intermediate wall. Cam means tilt the turntable into various inclined positions for resetting the phonograph record upon completion of the record message.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 251 words
An automatically resettable phonograph assembly comprising: a housing; a rotatable turntable mounted in said housing for rotation in a first position; a phonograph record mounted upon said turntable for rotation therewith, said record having at least one spiral groove formed therein with a starting position substantially at the periphery thereof and a predetermined terminal position; a tonearm located above said turntable and being pivotally connected at one end to said housing; a stylus connected to another end of said tonearm and adapted to engage said spiral groove; spring means for biasing the stylus end of said tonearm into said starting position; a speaker cone mounted on said housing above said tonearm with one end thereof adapted to contact said tonearm over a predetermined portion of said record extending from said starting position to said terminal position; a motor having a drive shaft; an endless belt entrained about said drive shaft and said turntable for rotating said turntable in response to the energization of said motor; means for pivotally urging said turntable against said stylus such that when said stylus reaches said predetermined terminal position said turntable is tilted into a predetermined second position relative to said first position; and means engaging said turntable in said predetermined second position for initially tilting said turntable past said first position and into a third predetermined inclined position so as to disengage said turntable from said tonearm thereby automatically returning said tonearm to said starting position and then repositioning said turntable into said first position.
Claim 2
Dependent Claim 251 words
An automatically resettable phonograph assembly comprising: a housing; a rotatable turntable mounted in said housing for rotation in a first position; a phonograph record mounted upon said turntable for rotation therewith, said record having at least one spiral groove formed therein with a starting position substantially at the periphery thereof and a predetermined terminal position; a tonearm located above said turntable and being pivotally connected at one end to said housing; a stylus connected to another end of said tonearm and adapted to engage said spiral groove; spring means for biasing the stylus end of said tonearm into said starting position; a speaker cone mounted on said housing above said tonearm with one end thereof adapted to contact said tonearm over a predetermined portion of said record extending from said starting position to said terminal position; a motor having a drive shaft; an endless belt entrained about said drive shaft and said turntable for rotating said turntable in response to the energization of said motor; means for pivotally urging said turntable against said stylus such that when said stylus reaches said predetermined terminal position said turntable is tilted into a predetermined second position relative to said first position; and means engaging said turntable in said predetermined second position for initially tilting said turntable past said first position and into a third predetermined inclined position so as to disengage said turntable from said tonearm thereby automatically returning said tonearm to said starting position and then repositioning said turntable into said first position.
Claim 3
Dependent Claim 72 words
A phonograph assembly as defined in claim 1 wherein said housing includes in combination; a speaker cone subassembly, in which said speaker cone is mounted; a motor subassembly in which said motor is mounted; a turntable subassembly in which said turntable is mounted and an intermediate wall of said housing separating said turntable subassembly from said speaker cone subassembly with said intermediate wall having a predetermined opening about which said tonearm traverses.
Claim 4
Dependent Claim 46 words
A phonograph assembly as defined in claim 2 wherein said turntable has a centrally disposed shaft with the lower end thereof flexibly connected to a bottom wall of said turntable subassembly and with its upper end extending through an elongated slot formed within said intermediate wall.
Claim 5
Dependent Claim 27 words
A phonograph assembly as defined in claim 3 wherein said flexible connection is formed by seating said lower end in a well formed in said bottom wall.
Claim 6
Dependent Claim 29 words
A phonograph assembly as defined in claim 3 further comprising auxiliary spring means mounted upon said intermediate wall for biasing said upper end of said shaft within said slot.
Claim 7
Dependent Claim 42 words
A phonograph assembly as defined in claim 5 further comprising cam means eccentrically mounted on said bottom wall for engaging said turntable in said second inclined position and for retilting said turntable to said third position and back to said first position.
Claim 8
Dependent Claim 29 words
A phonograph assembly as defined in claim 6 wherein said cam means has a circular geometry with an off-center shaft mounted to eyelet means extending from said bottom wall.
Claim 9
Dependent Claim 25 words
A phonograph assembly as defined in claim 6 wherein said speaker cone has a frusto-conical geometry with a flat base adapted to contact said stylus.
Claim 10
Dependent Claim 21 words
A phonograph assembly as defined in claim 8 wherein said stylus has an upper planar surface for engaging said flat base.
