Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
91 words
An electrically driven toy comprising a frame, having wheels rotatably carried thereon, an electric motor, an electric circuit for operating said motor, a selectively engagable gear transmission connecting said motor and said wheels and a control lever electrically interposed in said electric circuit and mechanically interposed in said gear transmission, said control lever being arranged to selectively operate said toy in a running mode by simultaneously engaging said gear transmission and completing said electric circuit and in an idling mode by simultaneously disengaging said gear transmission and opening said electric circuit.
Claim 2
Dependent Claim
91 words
An electrically driven toy comprising a frame, having wheels rotatably carried thereon, an electric motor, an electric circuit for operating said motor, a selectively engagable gear transmission connecting said motor and said wheels and a control lever electrically interposed in said electric circuit and mechanically interposed in said gear transmission, said control lever being arranged to selectively operate said toy in a running mode by simultaneously engaging said gear transmission and completing said electric circuit and in an idling mode by simultaneously disengaging said gear transmission and opening said electric circuit.
Claim 3
Dependent Claim
185 words
An electrically driven toy according to claim 1 wherein the gear transmission comprises a driving gear member connected to said motor, a driven gear member connected to said wheels and a gear member axially movable into and out of coupling engagement with at least one of said driving or driven gear members; said control lever being pivotably carried by said frame operable to move said axially movable gear member and connectable with an electrically conductive element; said electric circuit connecting said motor to electric source, said electrically conductive element and said lever member; said lever member being arranged on said frame for movement between a first position such as to cause the axially movable gear to be disengaged from at least one of said driving and driven gear members and to simultaneously separate the lever member from the said electrically conductive element to open said electric circuit and a second portion wherein said axially movable gear member is coupled operatively with both said driving and driven gear members and the lever member is in contact with said electrically conductive elements to close said electric circuit.
Claim 4
Dependent Claim
129 words
An electrically driven toy as claimed in claim 2, including a pair of electrically conductive elements connectable with said lever member, said lever being shiftable into contact with either of said conductive elements or to a position therebetween and out of contact with both of said conductive elements, said conductive element connecting said power source to opposite electric poles to thereby effect reversal of operation of said power source, at least one of said driving or driven gear members having a portion being out of coupling engagement with said axially movable gear member when said lever member is positioned out of contact with both said conductive elements, wherein said lever member is movable to operate said toy in three stages including normal advancing stage; idling stage and reversing stage.
Claim 5
Dependent Claim
40 words
An electrically driven toy as claimed in claim 2, wherein the axially movable gear member is mounted on an axially shiftable shaft which bears a disc member with a resilient member in engagement with one end of said control. lever.
