Abstract: A roller measurement fixture is comprised of a series of small in-line rollers mounted in one or more rows, forming a receiving cradle device. An extruded part to be measured is cradled in a semi-circular arrangement of the rollers and straightens as it settles under its own weight. The cradle device will accommodate many different cross-sections of extruded seal. The rollers are free to rotate as the part is placed into the fixture and properly located. Friction front these rollers is negligible, therefore the part remains in, or attains, its free state, without internal stresses, throughout the loading and measurement process. Thus, the extruded part is limp within the cradle, being loaded so as to contact a head or alignment stop at one end of the cradle. A floating stop riding on the rollers engages the other end of the part and cooperates with a scale on the cradle as a means of acquiring the measurements.

Abstract: A device for forming circles on a drawing surface that includes, in part, a first rotatable member and a second rotatable member. The first rotatable member is substantially flat and includes an opening formed therein. The second rotatable member is resiliently disposed within the opening. A first means elevates the first rotatable member above the drawing surface to prevent smearing of lines on the surface. A second means elevates the second rotatable member above the drawing surface to prevent smearing of lines on the surface and to engage the surface for stabilizing the rotatable member over the surface. The second mechanism elevates the second rotatable member to approximately the same level as the first rotatable member. A plurality of holes are disposed in the first and second rotatable members. The holes accommodate a marking instrument used for forming the circles.

Abstract: A template buffer element with cutouts which are larger than the interior cutouts of a template, attached to the template so that ink deposited on the drawing surface is separated from the working edge of the template by the buffer element, and the cutout edges of the buffer element are separated from the place of ink deposition by the difference between the dimensions of the buffer cutouts and the template cutouts. The buffer element may be a sheet of plastic or may be an array of strips made of elastomeric or nappy material which trap an air cushion under the template so as to facilitate template movement over the drawing and provide anchorage of the template to the drawing surface when the draftsperson presses down.
