    摘要： An infinitely variable drawing instrument for producing unlimited varieties of fanciful designs. The designs produced by the drawing instrument are of the repeated individual line type yet indexed around the circumference of a circle. After the various apparatus variables are set by the operator and a piece of paper is located on a drawing platen, the drawing tool or pen nib, located at the end of a drawing bar connected to the driving wheel is placed on the paper and the operator merely rotates the driving wheel by grasping a handle. The simple manual rotation of the driving wheel causes the drawing platen to rotate and, in addition, causes the drawing tool or pen nib to move and thereby draw the fanciful design on the paper. Thus, repeated lines, indexed on a circle, produce unlimited drawing designs. A guiding template and/or an intermediate bar can also be connected between the driving wheel and the drawing bar which provide additional variables for adjustment for making additional drawing designs. The ratio of the number of turns of the driving wheel to the number of turns of the drawing platen can be adjusted to provide additional adjustable variables.

    摘要： An amusement device including a base and a support carried by the base for suspending a pendulum above a marking surface. The pendulum includes a marker for tracing figures on the marking surface which is provided by a granular material contained in a bowl carried by the base. As the pendulum swings to and fro, the bowl can be rotated to control the tracing of geometrical figures on the marking surface.

    摘要： A compass for drawing geometric figures including ellipses and polygons of different sizes and shapes. The compass includes an upstanding center post having a lower point which supports the compass on the drawing surface. A disc forming a peripheral cam track is detachably mounted on a holder which in turn is pivotally mounted on a medial portion of the post. The disc is connected with a plunger which is slidable in the post for selectively adjusting the angle of the disc. A head member is rotatably mounted on an upper portion of the post. An adjustable multiplier link carrying a marking element is pivotally mounted at its upper end to the head member at a point which is radially spaced from the post a distance greater than the maximum radius of the cam track. In one embodiment a cam follower is suspended from the head member by a parallelogram linkage, and spring means is provided to urge the roller into contact with the cam track. In another embodiment the cam follower comprises a ring which turns in positive engagement about the disc, with stabilizer fingers being mounted to turn about the post. An alternate stylus arm is mounted below the cam follower for use in drawing figures of short radii. In both embodiments disc can be detached from its holder for replacement with parts having a varied cam track for drawing a different geometric figure.

    摘要： An instrument for inscribing closed geometrical planar loops comprising three arm members one of which is fixed and functions as the axis of the loop and the other two are joined together and to the axis member in a pivotal relationship such that when one of these arms is rotated in a radial direction the other arm carrying two scribe points generates the geometrical loop. This instrument is useful for generating such loops for drafting purposes and particularly for inscribing a figure skaters double loop on an ice skating surface.

    摘要： This drawing apparatus has adjustable mechanism for guiding a scriber to make curved lines and closed areas of different shapes over a wide variety. The adjustments are graduated and can be set to reproduce a predetermined curve or closed area. An element that moves in a circle on an adjustable base is connected with a scriber by a beam which is angularly movable and also movable in the direction of its length. This provides a simple and accurate mechanism for projecting the scriber along a desired path.
