Abstract
Abstract This device is a semiautomatic locator of any particular point on a surface by means of its X-Y coordinates. There are many situations where it is desirable to located a particular point on a large surface when only the X-Y coordinates of the point with respect to a datum are known. On a large surface, equipment of this type is necessary. This device comprises a support for the surface in question, two carriages, one movable along the X axis and the other along the Y axis, and electrical contacts on each carriage which cooperate with brushes on the carriages and are connected to registers to cause the registers to identify the X and the Y position of a pointer on the carriages at every instant. When the X-Y address of the point is registered, the pointer identifies that point on the surface.

Claim 1
Independent Claim
324 words
Apparatus for locating desired points on a surface, said apparatus comprising a surface upon which points are to be located, a first carriage mounted for movement across said surface in a first direction, a second carriage mounted on said first carriage for movement across said surface in a second direction, a pointer mounted on said second carriage to indicate a designated point on said surface, a first set of electrical contacts mounted on said surface, first brush means mounted on said first carriage for movement with said first carriage in contact with said first set of electrical contacts, a second set of electrical contacts mounted on said first carriage for movement therewith, second brush means mounted on said second carriage in contact with said second set of electrical contacts to move with said second carriage across said second set of contacts, each of said first and second sets of contacts comprising at least a first row of n contacts equally spaced and at least a second row having a group of m contacts for each of said n contacts of said first row, said n contacts having adjacent to and associated with it each of one of said groups of m contacts so that each of said first and second brush means simultaneously scans one n contact and a group of m contacts as said carriages are moved, means for connecting said first and second brush means to a source of electrical energy, and a display system comprising one set of display elements for each of said first and second sets of contacts, each of said display sets including a group of m display elements for each of said rows of contacts, means for connecting said individual contacts to individual display elements, and means for connecting said individual display elements to said source of electrical energy so that said display elements display the location of the point on said suRface indicated by said pointer.

Dependent Claim
324 words
Apparatus for locating desired points on a surface, said apparatus comprising a surface upon which points are to be located, a first carriage mounted for movement across said surface in a first direction, a second carriage mounted on said first carriage for movement across said surface in a second direction, a pointer mounted on said second carriage to indicate a designated point on said surface, a first set of electrical contacts mounted on said surface, first brush means mounted on said first carriage for movement with said first carriage in contact with said first set of electrical contacts, a second set of electrical contacts mounted on said first carriage for movement therewith, second brush means mounted on said second carriage in contact with said second set of electrical contacts to move with said second carriage across said second set of contacts, each of said first and second sets of contacts comprising at least a first row of n contacts equally spaced and at least a second row having a group of m contacts for each of said n contacts of said first row, said n contacts having adjacent to and associated with it each of one of said groups of m contacts so that each of said first and second brush means simultaneously scans one n contact and a group of m contacts as said carriages are moved, means for connecting said first and second brush means to a source of electrical energy, and a display system comprising one set of display elements for each of said first and second sets of contacts, each of said display sets including a group of m display elements for each of said rows of contacts, means for connecting said individual contacts to individual display elements, and means for connecting said individual display elements to said source of electrical energy so that said display elements display the location of the point on said suRface indicated by said pointer.
Claim 3
