Abstract
A throttle holding device is disclosed that allows an operator to hold open the throttle of the vehicle when the vehicle is not being driven. This increases the amount of available heat to the heating system of the vehicle cab and will allow the vehicle cab to be more quickly and efficiently heated. The throttle hold device of the present invention acts in conjunction with the parking brake and is actuated upon engagement of the parking brake through a pneumatic circuit. Upon actuation a piston is moved against a spring bias and causes the throttle cord of the vehicle to further open the throttle thus raising the idle speed of the vehicle. A shut-off switch is included on the pneumatic circuit to disconnect the system should the operator not desire that the higher idle be obtained. The shut-off switch is particularly useful in the summer months or whenever it is more important to conserve gasoline than to adequately heat the vehicle cab.
