Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
This configuration is also called a pantograph, [2] [3] however, it is not to be confused with the parallelogram-copying linkage pantograph. The linkage can be a one-degree-of-freedom mechanism if two gears are attached to two links and are meshed together, forming a geared five-bar mechanism.
Hollerith soon developed a more accurate and simpler to use Keyboard Punch, using a pantograph to link a punch mechanism to a guide pointer that an operator would place over the appropriate mark in a 12 by 20 matrix to line up a manual punch over the correct hole in one of 20 columns. [9]
The lowermost link of the parallelogram is fixed to two rigid supports. One vertical link at one end is connected to a profile tracer, which traces the profile of the letter to be drawn, and the second vertical link and the other horizontal link are jointly connected to a pencil that draws the exact shape of the profile traced.
The construction of physical measuring and calculating devices including rulers, protractors, pantographs, planimeters, integrators, and slide rules [2] [3] Mechanical linkages, pantographs, four-bar linkages, and the problem of converting rotary to linear motion, solved by the Peaucellier–Lipkin linkage and by Hart's inversor [4] [5]
According to the New York Times, here's exactly how to play Strands: Find theme words to fill the board. Theme words stay highlighted in blue when found.
A horizontal pantograph maintains identical planar (X and Y axis) movement, with two degrees of freedom; An angled pantograph descending from the bridge maintains identical vertical (Z axis) movement; A torsion beam maintains identical pen fore-and-aft tilt; A parallel linkage maintains identical pen side-to-side tilt
