Abstract

Abstract The frame of an engraving machine supports a slide for movement in a first horizontal direction. A pantograph is pivoted to the slide for movement about a vertical axis. A tool holder is supported by the pantograph. The tool holder is prevented from pivoting so that inscribed lines will have different widths.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 148 words
In an engraving machine comprising a frame, a slide on said frame, means on said frame for adjusting said slide in a first horizontal direction, a pantograph, said pantograph being pivoted to said slide for pivotable movement about a vertical axis, an elongated tool holder supported by said pantograph, and means removably mounted on said slide and removably connected to said tool holder for preventing said tool holder from pivoting about its longitudinal axis, said means including a guide rod horizontally disposed and generally perpendicular to said first direction, said means including a support for said guide rod, said support being releasably mounted only on said slide, means for preventing said support from pivoting relative to said slide, and means movably supported by said guide rod and connected to said tool holder for guiding movement of the tool holder in a horizontal direction parallel to said guide rod.
Claim 2
Dependent Claim 148 words
In an engraving machine comprising a frame, a slide on said frame, means on said frame for adjusting said slide in a first horizontal direction, a pantograph, said pantograph being pivoted to said slide for pivotable movement about a vertical axis, an elongated tool holder supported by said pantograph, and means removably mounted on said slide and removably connected to said tool holder for preventing said tool holder from pivoting about its longitudinal axis, said means including a guide rod horizontally disposed and generally perpendicular to said first direction, said means including a support for said guide rod, said support being releasably mounted only on said slide, means for preventing said support from pivoting relative to said slide, and means movably supported by said guide rod and connected to said tool holder for guiding movement of the tool holder in a horizontal direction parallel to said guide rod.
Claim 3
Dependent Claim 32 words
In an engraving machine in accordance with claim 1, wherein said support has converging surfaces with an included angle of approximately 135° engaging mating surfaces on a bracket fixed to said slide.
Claim 4
Dependent Claim 34 words
In an engraving machine in accordance with claim 1 wherein said support is connected to a bracket on said slide only by a pair of fasteners which engage the same surface on said bracket.
Claim 5
Dependent Claim 80 words
In an engraving machine comprising a frame, a slide on said frame, means for adjusting said slide in a horizontal direction relative to said frame, a pivot for a pantograph on said slide, a mounting bracket on said slide, a yoke having a guide rod horizontally disposed and perpendicular to said first mentioned direction, said yoke having only one upstanding support member releasably connected only to said bracket in a manner whereby said yoke cannot pivot relative to the slide.
Claim 6
Dependent Claim 80 words
In an engraving machine comprising a frame, a slide on said frame, means for adjusting said slide in a horizontal direction relative to said frame, a pivot for a pantograph on said slide, a mounting bracket on said slide, a yoke having a guide rod horizontally disposed and perpendicular to said first mentioned direction, said yoke having only one upstanding support member releasably connected only to said bracket in a manner whereby said yoke cannot pivot relative to the slide.
Claim 7
Dependent Claim 23 words
In an engraving machine in accordance with claim 4 wherein the ends of guide rod are supported by the ends of the yoke.
Claim 8
Dependent Claim 56 words
In an engraving machine in accordance with claim 4 wherein said support member has converging surfaces with an included obtuse angle on one side and engaging mating surfaces on said bracket, and a pair of fasteners on the opposite side of said support member and engaging said bracket for releasably interconnecting said yoke to said bracket.
Claim 9
Dependent Claim 15 words
In an engraving machine in accordance with claim 6 wherein said angle is approximately 135°.
Claim 10
Dependent Claim 25 words
In an engraving machine in accordance with claim 6 wherein said obtuse angle corresponds generally to the angle of pivotable movement of said pantograph pivot.
Claim 11
Dependent Claim 95 words
In an engraving machine comprising a frame, a slide on said frame, means on said frame for adjusting said slide in a horizontal direction, a pantograph, said pantograph being pivoted to said slide for pivotable movement about a vertical axis of approximately 135°, an elongated tool holder supported by said pantograph, a bracket on said slide, means supported by said bracket for preventing said tool holder from pivoting about its longitudinal axis, said means having converging surfaces which are vertically disposed, said surfaces cooperating with said bracket to define the pivotable range of said pantograph.
Claim 12
Dependent Claim 95 words
In an engraving machine comprising a frame, a slide on said frame, means on said frame for adjusting said slide in a horizontal direction, a pantograph, said pantograph being pivoted to said slide for pivotable movement about a vertical axis of approximately 135°, an elongated tool holder supported by said pantograph, a bracket on said slide, means supported by said bracket for preventing said tool holder from pivoting about its longitudinal axis, said means having converging surfaces which are vertically disposed, said surfaces cooperating with said bracket to define the pivotable range of said pantograph.
Claim 13
Dependent Claim 85 words
An attachment for use in an engraving machine comprising a yoke having a pair of generally horizontal arms supporting the ends of a horizontally disposed rod, a mounting on the lower end of said yoke adapted for mating contact with a bracket of an engraving machine, said mounting including vertically disposed inner converging surfaces whose included angle is about 135°, said mounting having fastener means for facilitating coupling the yoke to a bracket on an engraving machine, and a follower slidably supported by said rod.
Claim 14
Dependent Claim 85 words
An attachment for use in an engraving machine comprising a yoke having a pair of generally horizontal arms supporting the ends of a horizontally disposed rod, a mounting on the lower end of said yoke adapted for mating contact with a bracket of an engraving machine, said mounting including vertically disposed inner converging surfaces whose included angle is about 135°, said mounting having fastener means for facilitating coupling the yoke to a bracket on an engraving machine, and a follower slidably supported by said rod.
