Abstract
Abstract A system of master-slave synchro-servomechanism interconnectes, for conjoint movement, a fist 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-servomechanisms adapting them for conjoint rotation. The synchro-servomechanisms are reversible so that each stylus can control the other.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
199 words
In combination: a drawing support having an upper surface for receiving a drawing, an elongated first bar spanning across said surface, means mounting said first bar for back-and-forth sideways movement over the surface, a first tool carrier, means mounting the first tool carrier on said first bar for back-and-forth movement therealong, and first tool means on said first carrier, for following a generally linear path on said drawing on the support surface; a support for a three dimensional object, an interiorly open frame elevated above said support, an elongated second bar, means mounting said second bar on said frame for back-and-forth sideways movement across said opening, a second tool carrier, means mounting said second tool carrier on said second bar for back-and-forth movement therealong, second tool means on said second carrier, for following a generally linear path on the three dimensional object; first master-slave synchro-servo means interconnecting the two slide bars, such that movement of one of the slide bars will cause a corresponding movement of the second slide bar; and second master-slave synchro-servo means interconnecting the two tool carriers, such that movement of one of the tool carriers will cause a corresponding movement of the other tool carrier.
Claim 2
Dependent Claim
199 words
In combination: a drawing support having an upper surface for receiving a drawing, an elongated first bar spanning across said surface, means mounting said first bar for back-and-forth sideways movement over the surface, a first tool carrier, means mounting the first tool carrier on said first bar for back-and-forth movement therealong, and first tool means on said first carrier, for following a generally linear path on said drawing on the support surface; a support for a three dimensional object, an interiorly open frame elevated above said support, an elongated second bar, means mounting said second bar on said frame for back-and-forth sideways movement across said opening, a second tool carrier, means mounting said second tool carrier on said second bar for back-and-forth movement therealong, second tool means on said second carrier, for following a generally linear path on the three dimensional object; first master-slave synchro-servo means interconnecting the two slide bars, such that movement of one of the slide bars will cause a corresponding movement of the second slide bar; and second master-slave synchro-servo means interconnecting the two tool carriers, such that movement of one of the tool carriers will cause a corresponding movement of the other tool carrier.
Claim 3
Dependent Claim
34 words
The combination of claim 1, further comprising an information storage and retrieval mechanism and means for converting stored information in such mechanism to signals for controlling at least some of the slave synchro-servo means.
Claim 4
Dependent Claim
23 words
The combination of claim 1, wherein the first tool means is a tracing element and the second tool means is a milling element.
Claim 5
Dependent Claim
23 words
The combination of claim 1, wherein the first tool means is a drawing element and the second tool means is a tracing element.
Claim 6
Dependent Claim
39 words
The combination of claim 1, further including means for adjusting the second tool in zenith through a range of positions between a position relatively near the frame and a position relatively near the support for the three dimensional object.
Claim 7
Dependent Claim
56 words
The combination of claim 5, wherein the means for adjusting the zenith position of the second tool comprises a vertically elongated tool holder having a rack secured thereto, a drive gear on the second tool carrier meshing with said rack, and a small electric motor on said tool carrier which is drivingly connected to the gear.
Claim 8
Dependent Claim
24 words
The combination of claim 5, further including manually controlled control means for the said means for adjusting the zenith position of the second tool.
Claim 9
Dependent Claim
62 words
The combination of claim 1, further including means mounting both the first tool means and the second tool means for rotation about axes substantially perpendicular to the planes of travel of the first and second bars, and third master-slave synchro-servo means interconnecting the two rotatable tool means, such that rotational movement of one will cause a corresponding rotational movement of the other.
Claim 10
Dependent Claim
147 words
The combination of claim 1, further comprising a pair of elongated guide rods for each said elongated bar, each guide rod being positioned near an end of its bar and extending perpendicular to its bar and in parallelism with the guide rod at the opposite end of its bar, guide bearing means surrounding each guide rod, means connecting said guide bearing means to the adjoining end of the associated bar, an elongated line member in tension extending generally longitudinally of at least one of the guide rods for each bar, and wherein the master-slave synchro-servo means for each bar includes a synchro-servomechanism having a rotary shaft and a grooved wheel on said shaft which engages said elongated line member in tension, and means mounting said synchro-servomechanism on the bar, such that there is a driving contact between said grooved wheel and the elongated line member in tension.
Claim 11
Dependent Claim
122 words
The combination of claim 1, wherein the means mounting each tool carrier on its bar for back-and-forth movement therealong comprises an elongated guide rod carried by said bar and extending in parallelism with said bar, guide bearing means connected to said tool carrier and surroundingly engaging said guide rod, an elongated line member in tension supported on said bar and extending substantially in parallelism with said bar and said guide rod, and wherEin the said second master-slave synchro-servo means includes a synchro-servomechanism carried by the tool carrier, which mechanism includes a rotary shaft and a grooved wheel which engages said elongated member in tension, such that there is a driving contact between said grooved wheel and said elongated line member in tension.
Claim 12
Dependent Claim
102 words
The combination of claim 1, comprising first and second separate tables, wherein the top of the first table constitutes the said drawing support, wherein the second table comprises side support means, a generally horizontal support frame mounted by said side support means and held thereby at a position substantially intermediate the height of the second table, which frame constitutes the said support for a three dimensional object, and wherein said interiorly open 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 13
Dependent Claim
22 words
The combination of claim 11, wherein the drawing support comprises a light transmitting panel member, and lighting means below said panel member.
