    摘要： An ellipse drawing/cutting device is made up a base plate, a driving gear, a coil spring, a driven gear, a position retaining arm, a compression spring, a longitudinal measurement disc, a first fixing ring cover for the longitudinal measurement disc, a lateral measurement disc, a second fixing ring cover for the lateral measurement disc, a slide bracket assembly including a ruler frame, a pair of slide wings and cover two plates; a link bar, a plurality of anti-slip blocks disposed under the base plate, and a plurality of differently spaced pen insertion holes are distributed on the ruler frame which is relatively slidable on the lateral measurement disc. The longitudinal measurement disc and the lateral measurement disc are connected to each other by the link bar and movable in synchronism by way of the driven gear actuated by the spring operated driving gear so that a pen can be selectively inserted in proper one of the insertion holes to draw ellipses of different dimensions within ranges defined by the sizes of the longitudinal and lateral measurement discs.

    摘要： A device for cutting oval or circle shaped forms, as well as irregular or scalloped variations thereof, in picture frame mats or the like. It consists of a cutting unit releasably securable both to a stationary arm or a reciprocating arm. When the cutting mount is secured only to the stationary arm, as the stationary arm rotates, the cutting unit mount turns and a circle or oval form is cut. If the cutting unit mount is only secured to the reciprocating arm, a chain and sprocket or gear arrangement causes the reciprocating arm and cutting unit to move in and out as the oval or circle shaped form is cut. A mechanism for adjusting the desired irregular or scalloped shape is also provided.
