摘要： A drafting apparatus having a linear edge with first and second wheel means associated with the edge to rotatably move the linear edge across a planar drafting surface and wherein the wheels are of differing diameter so as to have the linear edge move across an arc defined within a circle toward which the linear edge is always pointed. The center of that circle is the vanishing point as conventionally utilized with perspective drawing techniques.

摘要： A multifunction instrument comprising four movable parts, including a first leg 12, an identical second leg 14, a pointer arm 16, and a connecting arm 18. Pointer arm 16 and connecting arm 18 are permanently but pivotally connected at pivot points 24A and 24B. Pivot points 20 A and B, 22 A and B, and 26 A and B are fastened by a removable fastener. The first leg 12 and second leg 14 have multiple holes drilled at intervals in the near end of each leg with a pivotal means of adjoining that allows for selecting various ratios. Legs 12 and 14 have a pivotal means of adjoining at pivot point 20A and 20B for determining angles and perspective. Legs 12 and 14 are calibrated and provide a straight edge, while flat surfaces provide printable space.

摘要： A drafting device (10) is provided for drawing parallel lines as well as true perspective lines, comprising carriage means (11) movable over a drafting surface (12) on wheel assembly means (20) and (21). A ruler (124) is located on carriage means (11) and has an unobstructed drafting edge (125) constantly co-linear with a true radial line to a chosen vanishing point. Selectively variable ratio transmission means (31), between wheel assembly means (20) and (21), permit ruler (124) to move over drafting surface (12) in a parallel or an arcuate manner about a preset vanishing point on or outside drafting surface (12). Magnet means are included for maintaining wheel assemblies (20) and (21) in frictional contact with drafting surface (12) and brake means are included to lock carriage (11) on drafting surface (12) in selected positions. Presetable stop means are provided to preset a plurality of vanishing points.

摘要： A portable drafting device and learning tool for laying out perspective drawing lines to enhance the realism of standard 30 degree base line isometric drawings and other similar drawings with different base line angles. The device comprises a rectangular drawing board including a plurality of holes disposed linearly in the upper corner portions thereof for pivotally mounting a plurality of articulated arm members in functional relationship with the drawing surface. The articulated arms comprise upper arm portions which are pivotally coupled to straight-edge members, each being disposed at approximately thirty degrees to horizontal. Upper arm portions are provided with a plurality of adjustment holes for alternate placement of pivot pins, or a slot to effect vertical adjustment of the articulated arms in relation to the drawing surface. Straight-edge members may be pivoted at varying angles in relation to upper arm members to enable selective adjustment of the desired vanishing point distance. The drafting apparatus includes a set of perspective scalers which are selectively utilized as measurement guides for adding perspective enhancement to the vertical and horizontal features of the drawings. The invention is of particular benefit to the student draftsperson or artist who does not possess the skill necessary to produce precise perspective drawings.
摘要翻译：一种便携式绘图装置和学习工具，用于布置透视图，以增强标准30度基线等轴测图和其他类似图形的不同基线角度的现实性。该装置包括：矩形绘图板，其包括在其上角部分中线性设置的多个孔，用于可枢转地安装与绘图面成功能关系的多个关节臂构件。铰接臂包括枢转地联接到直边构件的上臂部分，每个直立部件以水平方向大约三十度设置。上臂部分设置有多个用于枢转销的交替放置的调节孔或者用于实现铰接臂相对于拉伸表面的垂直调节的槽。直边构件可以相对于上臂构件以不同的角度枢转，以便能够选择性地调节所需的消失点距离。牵伸装置包括一组透视缩放器，其被选择性地用作用于将透视增强添加到附图的垂直和水平特征的测量引导件。本发明对于不具备产生精确的透视图所必需的技能的学生素描者或艺术家特别有益。

摘要： A drafting table includes vertical and horizontal straight edged supports together with drive mechanisms for moving the vertical straight edge such that it will always point to a viewing point and for moving the horizontal straight edges in plural different modes. In a first mode, the two horizontal straight edges are moved such that their edges always point to respective vanishing points. In a second mode the horizontal straight edges are moved such that one continues to point to a vanishing point while the other maintains a fixed angle with respect to horizontal, and so that their edges always intersect at a point along the line of view. The drive mechanisms for the horizontal straight edge supports can be disabled, reversed or their drive ratios changed in accordance with the particular drawing being made.
摘要翻译：牵伸台包括垂直和水平的直边支撑件以及用于移动垂直直边缘的驱动机构，使得它总是指向观察点并且以多种不同模式移动水平直边缘。在第一模式中，两个水平直边缘被移动，使得它们的边缘总是指向相应的消失点。在第二模式中，水平直边缘被移动，使得一个连续指向一个消失点，而另一个保持相对于水平方向的固定角度，并且使得它们的边缘总是在沿着视线的点相交。用于水平直边支撑件的驱动机构可以被禁用，反向或其驱动比根据具体图纸而改变。
