Claim 1

THE METHOD OF MAKING A PICTORIAL DRAWING FROM A MULTI-VIEW PROJECTION OF AN OBJECT DEFINABLE BY MUTUALLY PERPENDICULAR END, SIDE AND TOP PLANES, THE PICTORIAL DRAWING BEING A PROJECTION FROM THE OBJECT TO A VIEWING PLANE, SAID VIEWING PLANE MAKING FIRST, SECOND AND THIRD ANGLES WITH THE END, SIDE AND TOP PLANES RESPECTIVELY, COMRPISING THE STEPS OF: ORIENTING THE TOP VIEW ON A TRACING BOARD SO THAT THE END AND SIDE PLANES MAKE THE FIRST AND SECOND ANGLES RESPECTIVELY WITH A HORIZONTAL LINE REPRESENTING THE VIEWING PLANE ON THE TRACING BOARD, AND WITH A VIEWING POINT COMMON TO ALL VIEWS LOCATED AT A DESIGNATED POINT; TRACING THE TOP VIEW WITH THE TRACING POINT OF AN ELLIPSOGRAPH WHICH REPRODUCES THE TOP VIEW WITH VERTICAL DIMENSIONS REDUCED COMPARED WITH HORIZONTAL DIMENSIONS ON A DRAWING BOARD BY MEANS OF A DRAWING POINT; ORIENTING THE SIDE VIEW ON THE TRACING BOARD SO THAT THE TOP AND END PLANES MAKE THE THIRD AND FIRST ANGLES RESPECTIVELY WITH THE VIEWING PLANE, AND WITH THE VIEWING POINT LOCATED AT THE DESIGNATED POINT; ROTATING THE REPRODUCED TOP VIEW ABOUT THE VIEWING POINT TO A NEW POSITION SO THE JUNCTION OF THE TOP AND END PLANES IS VERTICAL FOR PROPER JOINDER OF A SIDE VIEW; TRACING THE SIDE VIEW WITH THE TRACING POINT SO THAT THE VIEW IS REPRODUCED ON THE DRAWING BOARD PROPERLY JOINED TO THE REPRODUCED TOP VIEW; ORIENTING THE END VIEW ON THE TRACING BOARD SO THAT THE TOP AND SIDE PLANES MAKE THE THIRD AND SECOND ANGLES RESPECTIVELY WITH THE VIEWING PLANE, AND WITH THE VIEWING POINT LOCATED AT THE DESIGNATED POINT; ROTATING THE JOINED REPRODUCED TOP AND SIDE VIEWS ABOUT THE VIEWING POINT TO A NEW POSITION SO THE JUNCTION OF THE TOP AND SIDE PLANES IS VERTICAL FOR PROPER JOINDER OF AN END VIEW; TRACING THE END VIEW WITH THE TRACING POINT SO THAT THE VIEW IS REPRODUCED ON THE DRAWING BOARD PROPERLY JOINED TO THE REPRODUCED TOP AND SIDE VIEWS, COMPLETING THE PICTORIAL DRAWING.

Claim 2

THE METHOD OF MAKING A PICTORIAL DRAWING FROM A MULTI-VIEW PROJECTION OF AN OBJECT DEFINABLE BY MUTUALLY PERPENDICULAR END, SIDE AND TOP PLANES, THE PICTORIAL DRAWING BEING A PROJECTION FROM THE OBJECT TO A VIEWING PLANE, SAID VIEWING PLANE MAKING FIRST, SECOND AND THIRD ANGLES WITH THE END, SIDE AND TOP PLANES RESPECTIVELY, COMRPISING THE STEPS OF: ORIENTING THE TOP VIEW ON A TRACING BOARD SO THAT THE END AND SIDE PLANES MAKE THE FIRST AND SECOND ANGLES RESPECTIVELY WITH A HORIZONTAL LINE REPRESENTING THE VIEWING PLANE ON THE TRACING BOARD, AND WITH A VIEWING POINT COMMON TO ALL VIEWS LOCATED AT A DESIGNATED POINT; TRACING THE TOP VIEW WITH THE TRACING POINT OF AN ELLIPSOGRAPH WHICH REPRODUCES THE TOP VIEW WITH VERTICAL DIMENSIONS REDUCED COMPARED WITH HORIZONTAL DIMENSIONS ON A DRAWING BOARD BY MEANS OF A DRAWING POINT; ORIENTING THE SIDE VIEW ON THE TRACING BOARD SO THAT THE TOP AND END PLANES MAKE THE THIRD AND FIRST ANGLES RESPECTIVELY WITH THE VIEWING PLANE, AND WITH THE VIEWING POINT LOCATED AT THE DESIGNATED POINT; ROTATING THE REPRODUCED TOP VIEW ABOUT THE VIEWING POINT TO A NEW POSITION SO THE JUNCTION OF THE TOP AND END PLANES IS VERTICAL FOR PROPER JOINDER OF A SIDE VIEW; TRACING THE SIDE VIEW WITH THE TRACING POINT SO THAT THE VIEW IS REPRODUCED ON THE DRAWING BOARD PROPERLY JOINED TO THE REPRODUCED TOP VIEW; ORIENTING THE END VIEW ON THE TRACING BOARD SO THAT THE TOP AND SIDE PLANES MAKE THE THIRD AND SECOND ANGLES RESPECTIVELY WITH THE VIEWING PLANE, AND WITH THE VIEWING POINT LOCATED AT THE DESIGNATED POINT; ROTATING THE JOINED REPRODUCED TOP AND SIDE VIEWS ABOUT THE VIEWING POINT TO A NEW POSITION SO THE JUNCTION OF THE TOP AND SIDE PLANES IS VERTICAL FOR PROPER JOINDER OF AN END VIEW; TRACING THE END VIEW WITH THE TRACING POINT SO THAT THE VIEW IS REPRODUCED ON THE DRAWING BOARD PROPERLY JOINED TO THE REPRODUCED TOP AND SIDE VIEWS, COMPLETING THE PICTORIAL DRAWING.
