Abstract
Abstract In a new method for the placement of sand, gravel or equivalent particulate material onto a sand trap, tee, putting green or other selected area of a golf course for construction or maintenance purposes, sand or other particulate material is pneumatically transported through a flexible conduit from an off-load site remote to the selected area to a nozzle positioned at the selected area and is sprayed from the nozzle onto the selected area. The new method eliminates the labor intensive prior method of wheelbarrowing sand or gravel from the off-load site to the selected site and the need then to rake or hoe the sand or gravel to properly spread it about the selected area.

In a method for the construction of a tee or putting green of a golf course, the improvement which comprises: providing a quantity of gravel at an off-load site remote to said tee or putting green, charging said gravel from said quantity thereof into a pneumatic pumping device that discharges said gravel into a flexible tube, pneumatically transporting said gravel through said flexible tube to a nozzle positioned at said tee or putting green and discharging gravel from said nozzle onto said tee or putting green.
Claim 5
Dependent Claim
174 words
In a method for the construction of a putting green of a golf course, the improvement which comprises: contouring terra firma to form a drainage basin for said putting green presenting a relatively smooth level surface, laying drainage pipe upon said surface and stapling it in place, providing a quantity of gravel at an off-load site remote to said putting green, pneumatically transporting said gravel from said quantity of gravel as a suspension in an air stream passing through a flexible conduit to said putting green, discharging gravel from said conduit onto said putting green to form a layer of gravel about four inches in depth over said surface, providing a quantity of sand at an off-load site remote to said putting green, pneumatically transporting said sand from said quantity of sand as a suspension in a air stream passing through said flexible conduit to said putting green, and discharging sand from said conduit onto said putting green to form a layer of sand about two inches in depth over said layer of gravel.
