US 5,165,175 A · Reverse image drawing apparatus

Abstract

A mirror image apparatus for use with a pantograph for drawing, engraving, milling, and similar applications wherein tracing and creating a mirror or reverse image is required. The apparatus is characterized by broadly having a stylus which operates between a first plane and a second plane. The first and second planes are parallel to each other with the second plane disposed above the first plane. One end of the stylus is used for drawing an image or tracing an image on the first plane while an opposite end of the stylus is used for engaging and creating on the second plane a mirror image of the drawing or tracing produced on the first plane. When drawing, the stylus may be a pen, pencil or any other drawing instrument wherein the stylus has opposite ends for drawing an image on the first plane while at the same time creating a mirror image on the second plane. When tracing with the stylus and using a template, the template may be mounted face up on a top surface of the first plane or mounted face down on a bottom surface of the second plane. While an image is traced by one end of the stylus in the template, the opposite end of the stylus creates a mirror image on the adjacent and parallel plane. The apparatus can further have a first stylus with one end drawing or tracing on the first plane and a second stylus pointed in an opposite direction from the first stylus. The second stylus engages the second plane for creating a mirror image of the drawing or tracing produced on the first plane.

Dependent claims

An apparatus for producing a mirror image on a workpiece of an original image which is drawn or traced on a template, the apparatus being designed to be mounted on a stand, the apparatus comprising:

a first stylus including a normally upwardly disposed end for drawing or tracing on a template;
a pair of upper support arms having a first end and a second end, said second end of said upper support arms being attached to an upper end of a pair of vertical spacers, the lower end of said vertical spacers being attached to a second end of a pair of lower support arms, the first end of said lower support arms being attached to the stand;
an adjustable template support plate for carrying a template, said adjustable template support plate and any template which it carries being disposed above said upwardly disposed end of said first stylus, so that said upwardly disposed end of said first stylus is positioned to be placed into contact with any such template during drawing or tracing operations, said template support plate being attached to and carried by said first end of said upper support arms;
a second stylus including an end for drawing, which is normally disposed in a substantially downward direction for engagement with a workpiece for drawing thereon;
and
connecting means for connecting said first stylus to said second stylus, whereby said second stylus is capable of producing a mirror image on the workpiece of an image drawn or traced by said first stylus on a template.

An apparatus for producing a mirror image on a second workpiece of an original image which is drawn or traced on a first workpiece, the apparatus being designed to be mounted on a stand, the apparatus including in combination, a first stylus including an end which is normally disposed in a substantially upward direction for drawing or tracing on the first workpiece, a second stylus including an end for drawing on the second workpiece, the end of the second stylus being normally disposed in a substantially downward direction, for engagement with the second workpiece for drawing thereon, and connecting means for connecting the first stylus to the second stylus, wherein the improvement comprises:

a pair of vertical spacers, each spacer having an upper end and a lower end;
a pair of upper support arms, each upper support arm having a first end and a second end, said second end of each said upper support arm being attached to said upper end of an associated vertical spacer;
a pair of lower support arms, each lower support arm having a first end and a second end, with the lower end of each said vertical spacer being attached to said second end of an associated lower support arm, the first end of each said lower support arm being designed for attachment to the stand;
and
a first workpiece support plate, for carrying the first workpiece, said first workpiece support plate and any first workpiece which it carries being disposed above the upwardly disposed end of the first stylus so that the upward end of the first stylus is capable of being placed into contact with the first workpiece during drawing or tracing operations, said first workpiece support plate being attached to and carried by said first ends of said upper support arms;
whereby the second stylus is capable of producing a mirror image on the second workpiece of an image drawn or traced by the first stylus on the first workpiece.
