Abstract
An arrangement for the drilling of holes to apply builders' hardware to windows in which an upper locating rail for accommodating a window frame is located between side members of a framework. A fixed drilling assembly with several spindles is located above the center of the locating rail. The spindles from the drilling assembly are lowerable. Two pipes above and parallel to the locating rail carry two auxiliary drilling assemblies which are coupled by a cable connection. The auxiliary drilling assemblies have several lowerable spindles and can be moved synchronously in opposite directions on the pipes.
Claims10
An arrangement for drilling holes to apply builders' hardware to windows comprising, in combination, a framework with two sides members;
- an upper mounting rail between said side members for receiving a blind or sash frame of a window;
- a stop rail attached to said mounting rail;
- fixed drilling means having two drilling units and a plurality of lowerable spindles above said mounting rail and at the center thereof;
- two tubular members above and parallel to said mounting rail;
- two auxiliary drilling units with a plurality of lowerable spindles on said tubular members and movable synchronously in opposite directions;
- cable connecting means connecting said two auxiliary drilling units so that movement of one of said auxiliary drilling units displaces the other auxiliary unit synchronously in the opposite direction, displacements of said auxiliary drilling units being relative to said fixed drilling means;
- linear displacement of one auxiliary drilling unit being transmitted directly through said cable connecting means to the other auxiliary unit for displacing said other auxiliary unit synchronously in the opposite direction, said cable connecting means comprising two runs of cable, each run being movable in opposite direction, each drill unit being attached to a separate run;
- first stop means abutted by said auxiliary drilling unit when drilling holes for a blind frame;
- and second stop means abutted by said auxiliary drilling unit when drilling for a sash and casement window frame, said second stop means being tiltable upward.
