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.

摘要： Drafting instrument for drawing ellipses using scribe arm and members capable of being pivotally connected at two points along the scribe arm, one of the members being constrained to move along a straight line congruent to the minor axis and the other of the members being constrained to move along a straight line congruent to the major axis, as the members reciprocate along their respective lines, a point of the scribe arm describes an ellipse.

摘要： An ellipsograph comprises an inner toothed horizontal ring gear serving as a support. A diametrically disposed main seat bar is mounted inside of the ring gear and rotatable about the center. A vertical shaft is mounted on the main seat with a revolving arm mounted thereon. A drawing implement such as a pen is slidably mounted on said arm. The main seat bar has a small gear provided on one end of the seat bar to be driven through meshing engagement with the inner teeth of the ring gear. Such movement is transmitted through a series of sprocket and chain trains disposed on the seat bar to the vertical shaft having the revolving arm. The track of the writing implement forms an ellipse when the seat bar is caused to rotate one revolution upon the ring gear.
摘要翻译：椭圆形包括用作支撑件的内齿水平齿圈。一个沿直径方向布置的主座椅杆安装在齿圈内部并围绕中心旋转。主轴安装在主座上，其上安装有旋转臂。诸如笔的绘图工具可滑动地安装在所述臂上。主座椅杆具有设置在座椅杆的一端上的小齿轮，以通过与齿圈的内齿啮合而被驱动。这种运动通过设置在座椅杆上的一系列链轮和链列传递到具有旋转臂的竖直轴。当座椅杆在环形齿轮上旋转一圈时，书写工具的轨道形成椭圆形。

摘要： An instrument for producing on the surface of a given sheet material a given geometric figure having preselected maximum width and length dimensions. A base through a suitable connecting structure carries a marking assembly which is freely movable with respect to the base and which has an inscribing member for inscribing on the surface of the sheet material the given geometric figure. An elongated bar is connected by a lower universal joint to the marking assembly and has an upper end adapted to be manipulated by the operator. Between its ends the bar extends slidably through an upper universal joint which can be adjusted in elevation so as to select a point along the bar about which the latter can be tilted in all directions. A template is formed with an opening through which the bar extends, the template having an inner peripheral edge conforming to the general configuration of the geometric figure which may, for example, be an ellipse, and a template-adjusting structure is operatively connected with the template for adjusting the angle of inclination thereof, the inner peripheral edge of the template limiting the extent to which the bar is tilted with respect to the above point while the bar is moved along the inner peripheral edge of the template to provide the given geometric figure on the surface of the sheet material. By way of adjusting the inclination of the template as well as the elevation of the universal joint through which the bar slidably extends it is possible to determine the maximum dimensions, namely the maximum length and maximum width, of the geometric figure.
