Abstract
Abstract This invention relates to an attachment which can be secured to a milling machine for measuring X-Y coordinates by removing the handle which is connected to a coordinate screw and attaching the handle on the other end of the attachment. Thus as the handle at its new location is rotated, it will not only drive the coordinate screw but will also drive a scale wheel which accurately indicates the extent of rotation of the coordinate screw.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
104 words
An attachment for insertion between the handle and coordinate screw of a milling machine or the like for determining coordinates in right angular relationship, comprising a drive shaft having a socket at one end for attachment to said lead screw to replace said handle after removal, and attaching means at the other end for attachment to said removed handle, said drive shaft including a worm, a housing surrounding said worm and including a worm wheel driven by said worm, and a calibrated circular scale detachably clamped to said worm wheel and cooperating with a reference zero setting on said housing immediately adjacent said scale.
Claim 2
Dependent Claim
104 words
An attachment for insertion between the handle and coordinate screw of a milling machine or the like for determining coordinates in right angular relationship, comprising a drive shaft having a socket at one end for attachment to said lead screw to replace said handle after removal, and attaching means at the other end for attachment to said removed handle, said drive shaft including a worm, a housing surrounding said worm and including a worm wheel driven by said worm, and a calibrated circular scale detachably clamped to said worm wheel and cooperating with a reference zero setting on said housing immediately adjacent said scale.
Claim 3
Dependent Claim
42 words
An attachment as recited in claim 1 wherein said scale has a knurled portion for facilitating turning relative to said housing, and including a wing nut for detachably clamping said scale to said drive shaft in zero setting relationship with said housing.
