Abstract A toy simulating a typewriter for enabling a child to compose a large number of sentences from a limited number of words, the toy having a keyboard with a plurality of keys, each key having a word imprinted thereon. A carriage is provided with paper receiving imprints of the words from hinged type arms operable upon depression of the keys, depression of one of the keys performing the imprinting operation and release of the key actuating a spacer frame coacting with an indexing bar for incrementing the carriage under force of a spring a predetermined distance.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
276 words
In a toy typewriter-like instrument, the combination comprising: a housing; a platen for receiving paper thereon, said platen being mounted on a carriage for movement on said housing to move the paper past a print position; a plurality of pivotable type arms mounted within said housing, each of said type arms having pads affixed to the free ends thereof with each of said pads having a type font thereon to imprint a different word of a pre-selected vocabulary; a plurality of key members pivotally mounted within said housing to form two rows of keys, each of said key members coacting with a predetermined one of said type arms, the key member for a given type arm having a portion thereon carrying indicia corresponding to the word on the pad of said type arm, said type arms and said key members being configured to operate each of said pads to said print position in response to actuation of said keys; a spacer frame rockably received within said housing about a pivot axis, one end of said spacer frame having a bar member portion disposed beneath each of said rows of said keys, each of said bar member portions extending in a line generally parallel to the pivot axis of said spacer frame; an indexing projection on the end of said spacer frame opposite said bar member portions; a downwardly extending indexing member on said carriage with an opening therein, the periphery of said opening being configured to receive said projection therein; and edge means within said opening for coacting with said projection to increment said carriage a predetermined distance in response to pivoting of said spacer frame.
Claim 2
Dependent Claim
276 words
In a toy typewriter-like instrument, the combination comprising: a housing; a platen for receiving paper thereon, said platen being mounted on a carriage for movement on said housing to move the paper past a print position; a plurality of pivotable type arms mounted within said housing, each of said type arms having pads affixed to the free ends thereof with each of said pads having a type font thereon to imprint a different word of a pre-selected vocabulary; a plurality of key members pivotally mounted within said housing to form two rows of keys, each of said key members coacting with a predetermined one of said type arms, the key member for a given type arm having a portion thereon carrying indicia corresponding to the word on the pad of said type arm, said type arms and said key members being configured to operate each of said pads to said print position in response to actuation of said keys; a spacer frame rockably received within said housing about a pivot axis, one end of said spacer frame having a bar member portion disposed beneath each of said rows of said keys, each of said bar member portions extending in a line generally parallel to the pivot axis of said spacer frame; an indexing projection on the end of said spacer frame opposite said bar member portions; a downwardly extending indexing member on said carriage with an opening therein, the periphery of said opening being configured to receive said projection therein; and edge means within said opening for coacting with said projection to increment said carriage a predetermined distance in response to pivoting of said spacer frame.
Claim 3
Dependent Claim
43 words
The combination according to claim 1 wherein said bar member portions have a plurality or pairs of upwardly extending projections, each of said pair of projections receiving a portion of a key member therebetween whereby to guide said key members during actuation thereof.
Claim 4
Dependent Claim
90 words
The combination according to claim 2 wherein said indexing member is configured adjacent the opening thereof to form a lower row of upwardly extending sawtooth projections and an upper row of downwardly extending projections intermediate said sawtooth projections, the indexing member projections being so configured that movement of said indexing projection against the force of the bias spring increments said carriage a portion of said predetermined distance and the movement of said indexing projection under force of its bias spring increments said carriage the remaining portion of said predetermined distance.
Claim 5
Dependent Claim
161 words
In a toy typewriter-like instrument, the combination comprising: a housing; a platen for receiving paper thereon, said platen being mounted for movement on said housing to move the paper past a print position; a unitary type arm cluster having a main portion secured within said housing, said main portion having a generally planar surface with an arcuate periphery with a plurality of type arms hingedly secured to said periphery by means of a reduced cross section hinge portion integral with said main portion, each of said type arms being normally operatively disposed in a direction transverse to the plane of said surface, the free ends of each of said type arms having a type font carrying pad affixed thereto; a plurality of key members, each of said key members pivoting one of said type arms to move the pad thereof to said print position; and means for incrementing said platen in response to actuation of any one of said key members.
Claim 6
Dependent Claim
161 words
In a toy typewriter-like instrument, the combination comprising: a housing; a platen for receiving paper thereon, said platen being mounted for movement on said housing to move the paper past a print position; a unitary type arm cluster having a main portion secured within said housing, said main portion having a generally planar surface with an arcuate periphery with a plurality of type arms hingedly secured to said periphery by means of a reduced cross section hinge portion integral with said main portion, each of said type arms being normally operatively disposed in a direction transverse to the plane of said surface, the free ends of each of said type arms having a type font carrying pad affixed thereto; a plurality of key members, each of said key members pivoting one of said type arms to move the pad thereof to said print position; and means for incrementing said platen in response to actuation of any one of said key members.
Claim 7
Dependent Claim
