ABSTRACT In a vehicle with a power source for moving said vehicle and for spreading liquid material on a road surface a material distributing apparatus is provided which includes means for automatically maintaining a constant application rate of the material to the road surface in response to changes in the width of the application pattern. The means includes a first portion which is responsive to the power source for providing a controlled rate of flow of the liquid material from the tank of the distributing apparatus, to a discharge element of the apparatus and onto the road surface so as to maintain a constant rate of application for the material despite changes in the speed of the vehicle. A second portion of the means is provided for adjusting the pattern provided by the discharge element. A third portion of the means is responsive to a change of the distribution pattern provided by the second portion of the means to cause the first portion to adjust its rate of flow of the liquid material to the discharge element -- in relation to the speed of the power source and the resulting speed of the vehicle -- such that the rate of application remains unchanged.
