    Abstract: The valve seat and guide machine comprises a base structure which supports a pantograph having a major arm and minor arm which moves slidably with respect to the major arm. A spherical head is supported by a number of sphere seats attached to the pantograph arm so that the spherical head can pivot around its centerpoint. A stepper motor provides small z-axis translation of the spindle which is contained in the spherical head and has a cutting bit and a pilot which extend from the bottom of the spherical head. A drive motor rotates a transmission linkage which is coupled to the spindle which rotates the cutting bit to cut the valve seat. Small x,y displacements are enabled by moving the entire spherical housing and its supporting sphere seats with respect to the support frame. The pantograph provides large z-axis displacement to remove the spindle from the cutting position and to provide clearance for movement to another machine site.

    Abstract: A flush bolt boring jig is rigidly attached to a drill. The drill has a bit which is the length of the bore to be formed in the door. The jig holds the drill rigidly so the bore being drilled in the door is parallel to the free end of the door. This is done by tracks mounted by clamps in such a way that the tracks are parallel to the free end of the door. The jig is attached to a pair of slide tubes which slide on the tracks. Since the drill is attached to the jig, as the hole in the door deepens, the drill moving with the slide tubes over the tracks moves in a straight line so that the bore being formed is exactly parallel to the free end of the door.

    Abstract: A drilling fixture for use in precisely drilling long bores in a workpiece, such as a door, comprises a pair of plates secured to each other in parallel spaced relationship, a sleeve mounted in the space between the pair of plates, and a pair of rotatable bearings carried by the sleeve for receiving the drill and securely holding same in position during the drilling operation. A clamp is secured to the pair of plates for clamping same to the workpiece in alignment with the longitudinal axis of the sleeve, and presetting means are provided for moving the sleeve at right angles to its longitudinal axis to thereby precisely preset same with respect to the workpiece. A pair of parallel sighting devices are fixed to the sleeve in spaced relationship along the sleeve longitudinal axis to precisely align the sleeve, and the drill when received therein, with the drilling axis.
