Abstract
Abstract A timer adapted to toy applications, and in particular for use in conjunction with toy ride-on vehicles is provided. The timer includes a spring-driven mechanical motor manually windable to at least a predetermined time duration state and a manually displaceable mechanical switch for the selective stopping and starting of the mechanical motor for the measurement of elapsed time.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A timer comprising: a housing, a spring-powered mechanical motor means mounted in said housing, said motor means including spring means and step up gear train means driven by said spring means for advancement during the relaxation of the tension in the spring means, switch means manually manipulatable from outside of said housing, said switch means being displaceable between a first position at which said switch means stops the advancement of said motor driven means and a second position at which said switch means permits said motor to advance, and speed governor means coupled to said gear train means for regulating the speed of rotation of said gear train means, said speed governor means being reciprocally oscillatable along a path by said gear train means, said switch means including a projection displaceable into and out of the path of said governor means when said switch means is displaced from its first toward its second position, said switch projection being formed with camming surfaces for displacing said governor means out of its path during displacement of said switch means from said second to said first position thereof.
Claim 2
Dependent Claim
185 words
A timer comprising: a housing, a spring-powered mechanical motor means mounted in said housing, said motor means including spring means and step up gear train means driven by said spring means for advancement during the relaxation of the tension in the spring means, switch means manually manipulatable from outside of said housing, said switch means being displaceable between a first position at which said switch means stops the advancement of said motor driven means and a second position at which said switch means permits said motor to advance, and speed governor means coupled to said gear train means for regulating the speed of rotation of said gear train means, said speed governor means being reciprocally oscillatable along a path by said gear train means, said switch means including a projection displaceable into and out of the path of said governor means when said switch means is displaced from its first toward its second position, said switch projection being formed with camming surfaces for displacing said governor means out of its path during displacement of said switch means from said second to said first position thereof.
Claim 3
Dependent Claim
88 words
The timer as claimed in claim 1 wherein said motor means includes first and second frame members supporting said gear train means and governor means therebetween, said governor means having a reciprocally oscillatable region extending outside of the space between said frame members for engagement by said projecting portion of said switch means, and wherein said switch means is pivotally mounted on said housing and includes first and second bearing surfaces alternately engaging against a frame member for defining said first and second positions of said switch means.
Claim 4
Dependent Claim
46 words
The timer as claimed in claim 2, wherein said switch means includes spring means intermediate said bearing surfaces to permit the displacement of said switch means between its first and second positions while positively positioning said switch means at each of said first and second positions.
Claim 5
Dependent Claim
59 words
The timer as claimed in claim 3, wherein said switch means is formed of a unitary body formed with essentially planar bearing surfaces at the bottom thereof defining an obtuse angle therebetween, said body of said switch member being formed with a slot extending substantially parallel to said bearing surfaces at the intersection thereof for defining said spring means.
