ABSTRACT:
Force upon the cutting head of a glass cutter will displace it rearwardly into the handle, thereby opening a valve by shifting an interconnecting tubular stem, admitting air into the reservoir. The air passes through the stem, the lubricant flows along its exterior, and both pass through a wick disposed to apply the lubricating fluid to the cutting wheel.
