Device for measuring and teaching scales of units

## Abstract

A teaching device for teaching students different scales of measure and aiding in the taking of accurate measurements by users of the device includes a first face that is marked with standard units of measure such as feet, inches, and fractions of inches. Each scale represents a different unit of measure scale and is arranged next to smaller scale in an order such that the feet measurement is arranged next to the inch scale. The inch measure is also arranged to the half-inch scale which is arranged next to the quarter inch scale. This continues such that each succeeding scale is arranged between a larger and smaller scale. A second face is marked with scales representing metric units of measurement. Each scale on the second face represents a unit of measurement on one order of magnitude smaller than the preceding scale.

## Background
BACKGROUND OF THE INVENTION
The present invention relates to a device for teaching the use of scales that represent various units of measure and for easily measuring a distance between two points. The units of measure may include either standard or metric units. The standard units of measure may comprise feet, inches, and fractions of inches. The metric units of measure may include meters measured in hundredths, thousandths and ten thousandths of meters. More specifically, the invention relates to a device having standard units of measure represented on one side thereof and metric units represented on an opposite side thereof.
Known types of rulers exist that include a face having an upper edge marked with inches and fractions thereof. A lower edge of the face is marked with millimeters and centimeters.
Another type of ruler comprises three sides for use in aiding a draftsman. Various faces of the three sides are marked with different units or scales. The draftsman rotates the ruler to a desired unit of measurement to measure a distance of a line or between two points.
Neither of the aforementioned rulers provides various scales that are labeled and clearly show a relationship of the various standard scales to one another along with the various metric scales to one another.

It may comprise wood, plastic, metal, fabric, paper, rubber or any other material on which a scale can be permanently marked.
The device includes a first side that comprises two vertical lines. Each vertical line is spaced approximately one-quarter of an inch from each edge of the ruler. Five horizontal lines are placed on the ruler are spaced one-quarter of an inch apart. The first line is arranged approximately one-quarter of an inch from the top of the device.
In one embodiment, the device includes a side having a list of measurements that are vertically represented in an ascending or descending order. The standard measurement side of the device is labeled with the following abbreviations: ft. corresponding to feet; in. corresponding to inches; 1⁄2 in. corresponding to half-inches; 1⁄4 in corresponding to quarter-inches; 1⁄8 in. corresponding to one-eighth inches; and, 1/16 in. corresponding to one-sixteenth of inches. These markings are provided between the vertical lines and the edges of the device. There are provided one hundred and ninety-two marks on the 1/16 inch scale. There are provided ninety-six marks on the 1⁄8 inch scale. Forty-eight marks are provided on the 1⁄4 inch scale. Twenty-four marks are provided on the one half inch scale. A one foot mark is provided on the ft. scale. Each scale is a different color.
In one embodiment, the device includes a series of metric scales arranged in an ascending or descending order. A vertical line is provided approximately three-eighths of an inch from the left side. A second vertical line is provided approximately three-eights of an inch from the right side. Four horizontal lines are placed one-quarter inch apart from one another and span the distance between the vertical lines. A series of notations are provided between the vertical line nearest the left side and the left side and the vertical line nearest the right side and the right side. The following marks are provided “mm”, “1⁄2 cm”, “cm”, and “dm”. The “mm” represents millimeters. The “1⁄2 cm” mark represents half-centimeters. The “cm” represents centimeters. The “dm” represents decimeters. There are provided three hundred marks on the millimeter scale. There are provided sixty 1⁄2 centimeters. Thirty marks are provided across the centimeter scale. Ten marks are provided across the decimeter scale. Each scale is a different color.
It is an object of the invention to provide a teaching and measuring device that increases the ability of an individual to identify and precisely measure objects to at least a sixteenth of an inch when using a standard scale provided on the device.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a view representing one side of the teaching device.
FIG. 2 is a view representing another side of the teaching device.
FIG. 3A is a prior art ruler.



DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a first side 10 of the device 1. The device comprises a top 2 and a bottom 4. The first side 10 includes several scales. Nearest bottom 4 is a millimeter scale 9. Provided above mm scale 9 is 1⁄2 cm scale 7. A cm scale 5 is arranged above 1⁄2 cm and below decimeter scale 3. As can be clearly seen, a user of the device 1 can easily recognize the relationship of the scales to one another. A vertical line 40 is provided at either side of the device.
FIG. 2 is a second side 20 of the device 1. The second side of the device represents standard measurement scales. A 1/16 inch scale 21 is located nearest the bottom 4. A 1⁄8 inch scale 19 is arranged above the 1/16 inch scale 21 and below the 1⁄4 inch scale 17. A 1⁄2 inch scale 15 is arranged below inch scale 13, which is in turn arranged above the foot scale 20. As can be realized, the scales are arranged such that there are twice as many lines as the scale arranged above it. This allows a user to quickly recognize the relationship between the various scales.
FIG. 3 is a prior art type of ruler that comprises both metric and standard scales provided on one side thereof. The metric and standard scales are provided on separate scales. However, the standard scales show only inches and fractions thereof mixed together in a single scale. This is very confusing for one who is learning to read a ruler. Moreover, it is very difficult to recognize the relationship of one standard scale to another.
It is to be understood that the invention is not limited to the exact construction illustrated and described above. Various changes and modifications may be made without departing from the spirit and the scope of the invention as defined in the following claims.
