- 14 - TITLE LOCK SHOE SYSTEM FOR HEAVY SASH ABSTRACT A lock shoe system for an especially heavy sash has shoes with lock bolts that can be moved into locking positions by means of a tool that moves a bolt from underneath a shoe so that the bolt interlocks with a lance in the jamb liner. Once the shoes are locked to the jambs, the sash can be lifted off the shoes, moved laterally within the jambs, and angled out of the window for removal. The shoes guide the sash to a centered position as it is returned to its platforms; and when the hoes are unlocked from the jambs, the lock bolts preferably retain the sash on the shoe platforms.
