Faithfull 200mm Square Leg Divider/ Compass

Product Information

A compass, more accurately known as a pair of compasses, is a technical drawing instrument that can be used for inscribing circles or arcs. As dividers, it can also be used as a tool to mark out distances, in particular, on maps. Compasses can be used for mathematics, drafting, navigation and other purposes.

In this exercise, you will read a sentence and identify whether a compass or divider would be used to complete the task. Sentence

The pencil lead draws the circle on a particular paper or material. Alternatively, an ink nib or attachment with a technical pen may be used. The better quality compass, made of metal, has its piece of pencil lead specially sharpened to a "chisel edge" shape, rather than to a point. This metal compass is noticeably corroded. The compass is held together by a screw at the top. A spring inside the mechanism below the screw allows the two legs to be squeezed together. The mechanism is marked on both sides: EAGLE PENCIL CO. (/) NEW YORK (/) PAT. DEC.11.1894 (/) PAT. GT.BRITAIN. The legs are embossed with a floral pattern. The two needle points slide into slots at the end of each leg. One point is made of the same metal as the compass. The other point is a metal that does not corrode, possibly German silver. The German silver point is reversible and holds a pencil lead in its other end. The school compasses (models 550 50, 550 55, 550 60, 559 WP 00) in our product range are specifically designed for younger children. These extra-safe precision compasses have a blunt safety needle to prevent injury. A divider is a compass that has two parts with a spike, and is used to show measurements of distances and lengths. It is called a divider because it is used to divide (make smaller things from a bigger thing) a distance in two, using geometry.

This metal instrument is held together by a screw at the top. A spring inside the mechanism below the screw allows the two legs to be squeezed together. The piece between the screw and spring is marked: EAGLE PENCIL CO. (/) NEW YORK (/) PATENTED. The legs are embossed with a floral pattern. Two needle points slide into slots at the end of each leg. One needle point is reversible and has a holder for a pencil lead at its other end. Compare to 304722.04, which is apparently an older version of this model. The mark refers to the patent Harrison Cole received in 1894 for a braking screw bolt that would help compasses or dividers remain set in position.

While the rules for using compass and divider are generally straightforward, there are some exceptions where they might not apply. Here are a few examples: When Working With Irregular Shapes Loose leg wing dividers [4] are made of all forged steel. The pencil holder, thumb screws, brass pivot and branches are all well built. They are used for scribing circles and stepping off repetitive measurements [5] with some accuracy. When working with irregular shapes, it may be difficult to use a compass or divider to create precise measurements. In these cases, it may be necessary to use other tools such as a protractor or ruler to get the desired measurements. For example, if you are trying to create a hexagon with irregular sides, it may be difficult to use a compass to create the angles and sides. Instead, you may need to use a protractor to measure the angles and a ruler to measure the sides. When Working With Large Objects

Case with hinged lid containing 1 compass, 1 sharpener 510 50, 1 eraser, 1 small pencil, 2 set squares, 1 ruler 15 cm and 1 protractor The screw through the hinge holds the two legs in position. The hinge can be adjusted, depending on desired stiffness; the tighter the hinge-screw, the more accurate the compass's performance. The better quality compass, made of plated metal, is able to be finely adjusted via a small, serrated wheel usually set between the legs (see the "using a compass" animation shown above) and it has a (dangerously powerful) spring encompassing the hinge. This sort of compass is often known as a "pair of Spring-Bow Compasses". Now that we have delved into the differences between compass and divider, it’s time to put that knowledge into practice. Below are some exercises that will help you improve your understanding and use of these two tools in sentences. Exercise 1: Identify The Tool

Compasses are usually made of metal or plastic, and consist of two "legs" connected by a hinge which can be adjusted to allow changing of the radius of the circle drawn. Typically one leg has a spike at its end for anchoring, and the other leg holds a drawing tool, such as a pencil, a short length of just pencil lead or sometimes a pen. The terms compass and divider are often interchanged, for each instrument can be used to draw circles, mark divisions (divide a given distance), or simply mark a distance. Technically, a compass is a drafting instrument that has one pen or pencil point and one sharp point that is positioned at the centre of the circle to be described, while a divider, on the other hand, has two sharp points, one for the centre and the other for scribing or marking. Caliper is a corruption of calibre, the diameter of a hole (as in a firearm) or of a cylindrical or spherical body. The outside caliper has inwardly curved legs that measure the diameters of solids created by rotating tools, such as lathe-turned objects, and the inside caliper has outwardly curved legs for measuring bores. Distances can be measured on a map using dividers,compasses with two spikes. The distance between the spikes on the map shows a distance in reality. Measuring how many times the compasses fit between two things on the map shows the distance between those things. A divider is a tool used for measuring and marking distances or dividing lines into equal parts. When using “divider” in a sentence, it is important to use it in the correct context to avoid confusion. Here are some examples: Compasses are drawing instruments that are primarily used to perform the following tasks in geometry:A compass is a tool used for drawing circles or arcs. When using “compass” in a sentence, it is important to use it in the correct context to avoid confusion. Here are some examples: When working with three-dimensional objects, such as spheres or cones, it may be difficult to use a compass or divider to create precise measurements. In these cases, it may be necessary to use other tools such as a caliper or computer-aided design (CAD) software to get the desired measurements. For example, if you are trying to create a sphere with a specific diameter, it may be difficult to use a compass to create the circle. Instead, you may need to use a caliper to measure the diameter or use CAD software to create a 3D model of the sphere. When Working With Non-mathematical Fields The divider is a tool that is primarily used to measure and transfer distances. Using the divider to draw circles and arcs is a common mistake. The divider is not designed to draw circles and arcs. This is because the divider has two legs that are fixed and cannot move. To draw circles and arcs, use a compass instead of a divider.
