Abstract
Abstract The apparatus is used for the automatic marking of drawings with alphanumeric and other drawing symbols. A carriage is designed to travel over the drawing without damaging the drawings. Means are provided to rigidly hold the carriage in place over the point on the drawing to be marked. Stylusses of varying sizes are interchangeably fitted on the carriage. Flexible cables connect the carriage to a control unit. Stored programs of the control unit are used to direct the marking operation. The unused stylusses are stored in appropriate receptacles in the control unit. A keyboard can be used to select the desired marking program.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
104 words
Apparatus for automatic marking of a drawing with alphanumeric symbols or other symbols or like markings, comprising: a control unit; a carriage connected by a flexible cable to said control unit and movable over the drawing; a marking device movably supported by said carriage and comprising a stylus, wherein the marking device is supported on said carriage by the ends of two arms pivotally mounted on said carriage about axes perpendicular to the drawing plane, the axes of the arms intersecting and the ends of said arms being pivotally connected together at the intersection of the axes, the lengths of the arms being adjustable.
Claim 2
Dependent Claim
104 words
Apparatus for automatic marking of a drawing with alphanumeric symbols or other symbols or like markings, comprising: a control unit; a carriage connected by a flexible cable to said control unit and movable over the drawing; a marking device movably supported by said carriage and comprising a stylus, wherein the marking device is supported on said carriage by the ends of two arms pivotally mounted on said carriage about axes perpendicular to the drawing plane, the axes of the arms intersecting and the ends of said arms being pivotally connected together at the intersection of the axes, the lengths of the arms being adjustable.
Claim 3
Dependent Claim
12 words
Apparatus according to claim 1, wherein the stylus is an Indian-ink marker.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 1, wherein a program selector comprises a keyboard in which individual keys are associated with individual stored programs.
Claim 5
Dependent Claim
17 words
Apparatus according to claim 3, wherein the keyboard is provided on a top surface of the carriage.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 1, wherein the carriage is provided with wheels for movement over the drawing, the wheels being driven by an electric motor.
Claim 7
Dependent Claim
50 words
Apparatus according to claim 5, wherein a plurality of magnets are provided on the underside of the carriage and said drawing is supported on a ferromagnetic support, said magnets and said ferromagnetic support being magnetically attracted to each, so as to hold the carriage firm with respect to the drawing.
Claim 8
Dependent Claim
17 words
Apparatus according to claim 6, wherein the rims of the wheels project slightly downwards from the magnets.
Claim 9
Dependent Claim
10 words
Apparatus according to claim 6, wherein the magnets are electromagnets.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 6, wherein the wheels support the carriage so that lower ends of the magnets are spaced from the drawing.
Claim 11
Dependent Claim
19 words
Apparatus according to claim 1, wherein each arm is provided with a feed screw driven by an electric motor.
Claim 12
Dependent Claim
