<h5>Historical Information</h5>
Patented by <a title="Brief history for Christian Becker" href="https://www2.humboldt.edu/scimus/Manufac/C_Becker/Becker.htm" target="_blank">Christian A. Becker</a> in 1916, and commercialized by L Oertling, Ltd, the chainomatic balance - or as we know it in its exhibit at Michigan Technological University, the chainomatic analytical scale - was crafted to serve the increasing demands of society and academia. For centuries earlier, the traditional two-pan balance was used for all sorts of measurements of weight. In particular some careful measurements were required for accurate measures in chemistry, engineering, and other academic fields, as well as in the measure of small but valuable items such as precious metal coins, gems, ivory, etc. The chainomatic balance was conceived as a relatively easily-implemented, accurate measure of weight and balance. It helped to ease the burden of scientists of the era that would need to balance a two-pan scale to extreme accuracy using tweezers. Meanwhile, the chainomatic scale could provide careful adjustments with the turning of a knob to alter the position and turn weight of a chain attached to the beam. The chainomatic balance was commonly used where precision as fine as within around 10 milligrams was required and could be afforded. <br /><br /> Given the nature of the chainomatic scale, it is the assumption of the authors that this particular model was used by the various scientific departments of Michigan Technological University for its nominal use of careful measurements of mass. However, such information is not present in the exhibit, and sources lack any explicit accounts of this model’s use or history. Being a mining school in its earliest days, Michigan Tech may have used chainomatic scales to measure out the ore and yield involved in copper refinement, or in researching techniques in more careful, deliberate mining.

Description

<h5><strong>Physical Description</strong></h5>
The scale’s frame is a rectangular prism composed of a russet-colored wood, with some sun bleaching occurring to its front face. Three tarnished metal feet, one on each front corner and one placed in the middle of the rear side, hold the frame about 2 cm above the ground. There are four glass-paneled doors that allow access to the actual measurement apparatus. A 145 mm x 235 mmm door on the top side that can be removed fully from the frame, and has a handle on the left and right sides that can hold it securely in place. Two 162 mm x 150 mm hinged doors are set into the left and right side of the frame, with securing handles being placed on the side of the door the corresponds to the frame’s front side. The fourth door is the primary access way to the scale; it is a vertically sliding door, 289 mm x 230 mm, with a worn white knob of an unknown material at the base that can be used to lift it up. The door can be lifted completely out of its slots, but two strings prevent it from being detached from the frame completely. The rear side is made up almost entirely of a pane of glass. <br /><br /> Two letter and number combinations are printed on the frame: MCMT-9614 appears on the bottom left of the frame’s left side; R20770 on the bottom left of the frame’s right side. They may be the scale’s make and model numbers, or possibly relate to the production and manufacturing process of the scale.<br /><br /> The scale apparatus itself rests on a polished black layer, made of either ceramic or stone, that is positioned 40 mm above the bottom of the frame and extends past the four wooden sides. Two metallic gray weighing platforms hang about 20 mm above the ceramic base, suspended from hooks about 220 mm above the base. A metal hanger for suspending weight is welded between the <a title="Image of Original Wrappings for the Chain" href="https://www2.humboldt.edu/scimus/HSC.36-53/Images/CB_AB2_ChBox_contents.jpg" target="_blank">two small metal rods</a> that hold the platforms to their suspension hook, though the hanger for the left platform has broken off, and a metal peg has been secured to each of that platform’s rods to hold the hanger up. The stirrups for the the platform suspension hooks rest below a “100 mm” measurement poise that tops the scale apparatus; this measured displacement can then be used to determine the weight of the objects being measured, in grams. Descending from the measurement poise, the scale’s pointer ends at a small cream-colored piece of plastic, 6-sided—though similar in shape to a hypotenuse. The plastic piece has the words “Christian Beckering Inc., New York” printed across the bottom, while the scale’s measurement lines are printed almost microscopically along the top. The scale’s central pillar, support beams, and base are all formed out of brass. A solid brass cylinder also extends out from the base toward the front of the frame. An adjustable-angle magnifying glass that is used to make out the measurement lines can be slid on and secured to this cylinder if the scale is undergoing frequent use, though the lens has been removed from this particular scale’s magnifying glass. <br /><br /> Two apparatus control knobs are located on the wooden frame: one on the front side, directly below the front door’s lifting knob; and one on the right side, at the middle along the top. The front knob can be rotated clockwise and counterclockwise to adjust the sensitivity of the measurement platforms. The right knob can be rotated in either direction, and pushed in and pulled out, though not entirely. The particular purpose of this knob is unknown because its mechanisms in conjunction with the rest of the scale are broken, though it may have once served to adjust the balance of the scale. <br /><h5><strong>Functional Description</strong> </h5>
In order to use the scale, the user must adjust the knob on the front of the wood box that will move the stoppers under the metal plates. This will keep the scale from moving when adding the object/weights to each of the metal plates. The user then places the object to be weighed on one of the metal plates, and places weights of known value (not included in this particular artifact), on the other plate. Then the user turns the knob until the stoppers are no longer beneath the metal plates, and the plates are hanging freely. If the pointer hangs directly straight down, the load is balanced. If not, the process needs to be repeated by placing the stoppers beneath the plates again, then adding or removing weight in order to get the pointer to hang straight down. While the user is observing the pointer, it is important to close the glass door on the box to prevent airflow from impacting the results. The user will continue this until the pointer hangs straight down. Once the pointer is hanging straight down the user can sum the amount of weights added to the pan to find the weight of the object. The weight of the object is equal to the amount of added weight when the load is balanced.<br /><br /><a title="The Care and Use of a Balance" href="https://www2.humboldt.edu/scimus/Instruments/UseCareBal/UseCareBal.htm" target="_blank">The Care and Use of a Balance</a>

History of the Object
<p>Dietzgen engineering supply company was founded in 1885 in Chicago by the German immigrant Eugene Dietzgen. The first manufacturing facility opened in 1893, producing T-squares, drawing boards, surveying instruments, drafting instruments, and other engineering supplies. High quality and craftsmanship of the tools made Dietzgen sets highly sought after.</p>
<p>The specific set of drafting equipment that is in the Alumni House is a Dietzgen Master - Pro 1213PJ. Sets such as this were produced throughout the 1930s, 40s, and 50s. The set that resides on the campus was produced within the 1930s, having a unique configuration within the box that is much more rare than the later versions from the 1950s. These tools were likely used for surveying and architectural drawings throughout its time at Michigan Technological University. The time of arrival at the university is unknown.</p>

Description
An account of the resource
<p><strong>Physical Description: </strong>The drafting set is stored in a simple grey case with a red felt interior. The case only has three words on the outside cover: “Made in Germany”. The only markings on the inside of the case are the letters “DS” written in marker on the felt; presumably the initials of the original owner. Though the case is plain and simple, the drafting tools contained inside are intricate and precise. The set includes a large and small compass, a beam compass (with an extension), attachments for the compasses, both a ruling and technical pen, a pair of dividers, and a screwdriver. With these tools come replacement parts carried in capsules. The replacement parts consist of screws and heads for the compasses and ruling pen.</p>
<p><strong>Functional Description: </strong>The purpose of drafting tools is to create precise diagrams which convey how something functions or should be constructed. Drafting plays an important role in manufacturing, engineering, architecture, and cartography.</p>
<p>The function of the case is simply to store and protect the drafting tools, and keep them neat and organized. The interior of the case has slots fitted to the tools so that there is minimal movement when the case is carried. The dividers are used to quickly compare and transfer measurements, and to divide lines into segments. The compasses are used for drawing circles and arcs, and come in a variety of sizes to allow the drawing of very small circles in the case of the small compass, and very large circles in the case of the beam compass. The technical pen is used in order to draw lines of a fixed width, where as the ruling pen allows for the width of lines to be varied. There are a number of attachments that can used with the ruling pen and compasses in order to change between writing in ink and lead. Typically the initial revisions of a draft are done with lead, and then the pens are used later to create the final draft.</p>

<span style="text-decoration:underline;"><br /><span>Physical Description:</span></span> The Pickett 1000 slide rule is made of three rectangular bars of aluminum alloy coated in plastic with grooved slides. Two bars are connected at the end with braces that are mounted to the flat side of the bars and the third bar is free to slide between them, held in place by slide tension springs. The two outer bars are called stators and the inner bar is referred to as the slide. The slide rule also has a courser made of two flat lenses held together by aluminum above and below the upper and lower stators. Each bar of the Pickett 1000 slide rule has at least one scale on it. The front side of the slide rule has the DF scale on the upper stator CF, CIF, CI and C scales on the slide and D and L scales on the lower stator. The back side of the slide rule has an A scale in the top stator B, T, ST, and S scales on the slide and K and D scales on the lower stator.<br /><span style="text-decoration:underline;"><br />Functional Description:</span> <span>Slide rules work on a system of logarithms. In order to do multiplication the slide rule adds two logarithms and takes the antilog to determine the answer. Because the slide rule uses logarithmic scales, the operation is simplified. If the user wanted to multiply two numbers together they would move one of the indices on the C scale to the first number that they wish to multiply on the D scale .They would then move the cursor to the second number in the multiplication on the C scale and look at the corresponding number on the D scale. So, if you wanted to multiply 2 and 4 you would move the left index of the C scale to the 2 on the D scale, move the cursor to the 4 on the C scale and see that the answer Is 8. To do division the inverse is done. To find the square and square root the A or B scale and the D scale are used. Locate the number of the square root you want to find using the cursor, when found the corresponding number on the D scale is the answer. To find the square the inverse is found. cube and cube root K scale and the D scale are used. To find the cube root take the number and find it on the K scale read the corresponding number on the D scale. To find the cube the inverse is performed. Scales available on the slide C and D used for multiplication and Division, CF and DF used for multiplication and division when the C and D scales run out. The CI and CIF scales are the inverse of the C scale and CF scale respectively. The S T slides are used for sine and tangent of greater than 5.7 degrees while the ST slide is used for degrees less than 5.7 degrees. The A and B scales are used in the calculation of squares and square roots. The L scale is used for the Log base 10 of a number.</span>.<br /><span><span><br /></span></span>

Description
An account of the resource
Planimeters in general are used to calculate the area enclosed inside an arbitrary shape on a plane. Polar planimeter's, 103 types, perform a mechanical integration as a stylus is traced around the perimeter of the shape in question. Because the shape does not need to be regular, these devices were often the only way to calculate the area accurately with any rapidity whatsoever.
This model is of the "Amsler" type, developed by Swiss mathematician Jacob Amsler in 1854, and is known as a Type 2 Amsler (the diagnostic feature being the arc at the elbow).
