Abstract
Abstract A system of master-slave synchro-servo mechanism interconnects, for conjoint movement, a first stylus mounted for two dimensional movement across a paper or other flat surface, and a second stylus mounted for a corresponding two dimensional movement over a three dimensional object. The second stylus is adjustable in the third dimension, and both styluses may be rotatable and interconnected by master-slave synchro-servo mechanisms adapting them for conjoint rotation. The synchro-servo mechanisms are reversible so that each stylus can control the other.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
In combination: a support frame for a three dimensional object, an upper frame comprising interconnected side members defining an interior opening, means supporting said upper frame in a position elevated above said support frame, an elongated support bar, means mounting said support bar on said upper frame for backand-forth sideways movement across said opening relative to said support frame and any three dimensional object thereon, a tool carrier, means mounting said tool carrier on said support bar for back-and-forth movement therealong, and tool means on said carrier, for following a generally linear path on the three dimensional object; electric motor means for moving said support bar back-and-forth sideways across said opening; electric motor means for moving said tool carrier back-and-forth along the support bar; and means for adjusting the tool in zenith throughout a range of positions between a position relatively near the upper frame and a position relatively near the support frame for the three dimensional object.
Claim 2
Dependent Claim
158 words
In combination: a support frame for a three dimensional object, an upper frame comprising interconnected side members defining an interior opening, means supporting said upper frame in a position elevated above said support frame, an elongated support bar, means mounting said support bar on said upper frame for backand-forth sideways movement across said opening relative to said support frame and any three dimensional object thereon, a tool carrier, means mounting said tool carrier on said support bar for back-and-forth movement therealong, and tool means on said carrier, for following a generally linear path on the three dimensional object; electric motor means for moving said support bar back-and-forth sideways across said opening; electric motor means for moving said tool carrier back-and-forth along the support bar; and means for adjusting the tool in zenith throughout a range of positions between a position relatively near the upper frame and a position relatively near the support frame for the three dimensional object.
Claim 3
Dependent Claim
31 words
The combination of claim 1, further including means mounting said tool means for rotation about its axis, which axis extends substantially perpendicular to the plane of travel of the support bar.
Claim 4
Dependent Claim
145 words
The combination of claim 1, further comprising a pair of elongated guide rods for said support bar, each guide rod being positioned near a separate end of the bar, and extending perpendicular to said bar and in parallelism with the guide rod at the opposite end of the bar, guide bearing means surrounding each guide rod, means connecting said guide bearing means to the adjoining end of the support bar, an elongated line member in tension extending generally longitudinally of at least one of said guide bars, and wherein the electric motor means for moving said support bar includes a small electric motor carried by the support bar having a rotary shaft, and a grooved wheel on said shaft which engages said elongated line member in tension, such that there is a driving contact between said grooved wheel and the elongated line member in tension.
Claim 5
Dependent Claim
82 words
The combination of claim 1, comprising a table having side support means, a generally horizontal frame assembly mounted by said side support means and held thereby at a position substantially intermediate the height of said table, which frame assembly constitutes the said support frame for a three dimensional object, wherein said upper frame is mounted atop said side support means and comprises four side portions, each of which is connected to its adjoining two side portions by a substantially right angle corner.
Claim 6
Dependent Claim
64 words
The combination of claim 4, wherein said frame assembly comprises an outer frame part pivotally mounted on said side support means for pivotal movement about a generally horizontal axis, and an inner frame part mounted on said outer frame part for pivotal movement about a second axis which is perpendicular to the first axis and is within the plane of the outer frame part.
Claim 7
Dependent Claim
43 words
The combination of claim 5, further comprising means for adjustably supporting said frame assembly between said side support means, so that the height of said frame assembly and the vertical spacing of said first axis to said interiorly open frame can be adjusted.
Claim 8
Dependent Claim
34 words
The combination of claim 1, further comprising an information storage and retrieval mechanism and means for converting stored information in said mechanism to signals for controlling at least some of said electric motor means.
