Abstract
Abstract Apparatus for the manufacture of three dimensional reproductions of an object from a series of photographic records thereof taken at predetermined angular and longitudinal intervals. It has means for projecting the series of photographed outlines of the object one by one onto a screen, means for scanning the outlines, means for transmitting the scanning movements onto a cutting tool, and a table carrying a block of material into which the cutting tool cuts or carves the scanning tool.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
193 words
An apparatus for the manufacture of three-dimensional reproductions of an object, such as an article, a person, or a part thereof, from a photographic record of the object taken at regular intervals, comprising a pointer-tool assembly which comprises a head for driving a rotary cutting tool and scanning pointer means interconnected and mounted for simultaneous displacement so that each displacement of the pointer is exactly copied by the tool, said head being mounted for displacement horizontally and vertically with the axis of the tool being retained in a single vertical plane, and further comprising a projector and screen unit for showing the said photographic records and a work table adapted to carry adjustably and displaceably a block of material from which the reproduction is to be made, the scanning pointer means comprising a carriage including means for displacing the pointer so that it scans the profile of the photographic record projected onto said screen, said pointer tool assembly including two rigidly interconnected carrier members slidable on slide means, one of the carrier members carrying the said scanning pointer means and the other carrying the head in which the rotary cutting tool is clamped.
Claim 2
Independent Claim
193 words
An apparatus for the manufacture of three-dimensional reproductions of an object, such as an article, a person, or a part thereof, from a photographic record of the object taken at regular intervals, comprising a pointer-tool assembly which comprises a head for driving a rotary cutting tool and scanning pointer means interconnected and mounted for simultaneous displacement so that each displacement of the pointer is exactly copied by the tool, said head being mounted for displacement horizontally and vertically with the axis of the tool being retained in a single vertical plane, and further comprising a projector and screen unit for showing the said photographic records and a work table adapted to carry adjustably and displaceably a block of material from which the reproduction is to be made, the scanning pointer means comprising a carriage including means for displacing the pointer so that it scans the profile of the photographic record projected onto said screen, said pointer tool assembly including two rigidly interconnected carrier members slidable on slide means, one of the carrier members carrying the said scanning pointer means and the other carrying the head in which the rotary cutting tool is clamped.
Claim 3
Dependent Claim
20 words

Claim 4
Independent Claim
179 words
An apparatus for the manufacture of three-dimensional reproductions of an object, such as a article, a person, or part thereof, from a photographic record of the object taken at regular intervals, comprising a pointer-tool assembly which comprises a head for driving a rotary cutting tool and scanning pointer means interconnected and mounted for simultaneous displacement so that each displacement of the pointer is exactly copied by the tool, said head being mounted for displacement horizontally and vertically with the axis of the tool being retained in a single vertical plane, and further comprising a projector and screen unit for showing the said photographic records and a work table adapted to carry adjustably and displaceable a block of material from which the reproduction is to be made, the scanning pointer means comprising a carriage including means for displacing the pointer so that it scans the profile of the photographic record projected onto said screen, said tool head being driven by an electric motor attached to the head, said pointer tool assembly being horizontally and vertically displaceable by means of slides.
Claim 5
Independent Claim
179 words
An apparatus for the manufacture of three-dimensional reproductions of an object, such as a article, a person, or part thereof, from a photographic record of the object taken at regular intervals, comprising a pointer-tool assembly which comprises a head for driving a rotary cutting tool and scanning pointer means interconnected and mounted for simultaneous displacement so that each displacement of the pointer is exactly copied by the tool, said head being mounted for displacement horizontally and vertically with the axis of the tool being retained in a single vertical plane, and further comprising a projector and screen unit for showing the said photographic records and a work table adapted to carry adjustably and displaceable a block of material from which the reproduction is to be made, the scanning pointer means comprising a carriage including means for displacing the pointer so that it scans the profile of the photographic record projected onto said screen, said tool head being driven by an electric motor attached to the head, said pointer tool assembly being horizontally and vertically displaceable by means of slides.
Claim 6
Dependent Claim
18 words
