Abstract
Abstract A toy road grader having a grader blade mounted crosswise on the underside of the front portion of the grader body which is yieldably held in a raised position above the ground surface under spring tension and connected to an upright handle mounted on the body for rocker movement about a transverse axis whereby as the handle is swung forwardly it will lower the blade against said spring tension into engagement with the ground surface. The blade is pivoted on a vertical axis and is adjustable between different locked angular positions relative to the line of travel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
In a toy road grader having a body supported on front and rear ground wheels with a forwardly arched front body portion having its forward end supported on an axle carrying the front wheels, a. a blade support extending longitudinally under said body portion with its forward end journaled on said axle, b. a control handle pivoted near its lower end on a transverse horizontal axis to said body portion, c. a rigid link connecting the blade support to the handle forward of said axis whereby as the upper end of the handle is moved forwardly about said axis the blade support will be lowered, d. spring means acting between the said body portion and handle to yieldably retain the handle in a rearward position, and e. a grader blade mounted on the blade support in depending relation thereto and extending transversely of said body portion normally in elevated position above the ground but adapted to move into engagement with the ground as the blade support is lowered.
Claim 2
Dependent Claim
