Since writing with the electric pen was so unnatural, because no one can write at a perfect perpendicular angle, the Woodbury Holder was sold to make the writing easier. The Woodbury Holder literally held the electric pen so it was always at a 90 degree angle. "The weight of the Electric Pen rests upon the point of the tube and the small leg which projects to the right of the holder" (Wheeler). The holder or handle extends outwards from the pen and looks like and is in the position of an actual pen. By moving the pen-like handle and exerting a little pressure the Electric Pen will move as you move the handle. The displacement of the writing is similar to that of cameras in which the lens and the view finder are at different angles and must be rectified before shooting the picture. The Woodbury Holder displaces the point of writing to make it easier for beginners to use the pen and also lessen the "jar" of the pens vibrations.

History

The patent for Edison's Electric Pen, entitled Improvement in Autographic Printing was filed on March 13, 1876. The Electric Pen was Edison's "first experimental work in document copying and multiple duplication" (Baldwin 69). The device was invented for the niche market of business men needing to multiple copies of legal documents. The pen, however, was more versatile than for just business purposes and was popular and sold well. Beginning at the bargain price of just 35 dollars the Edison Electric Pen was marketed for any use from personal letters, music, contracts, manifestos, and artistic drawings. The pen was first sold exclusively to the east coast but quickly exanded to the midwest and to British Columbia and England. Eventually, Edison sold the rights to the Western Electric company, but the rights and patent finally ended up in the hands A.B. Dick of Chicago who developed the next reduplication invention: the mimeograph.

Mechanics

The patent by Edison, describes the writing of the pen as, "patterns for embroidery and for fresco painters... made of paper" (patent). By having a sharp needle at the end of a stylus that moves rapidly up and down, small perforations can be made into paper or wax paper to make stencils.To break it down, the pen consisted of a metal tube or stylus resembling a pen or writing device. At the end would be the needle connecting to wires inside the tube that connected to a small electromagnetic engine on the top of the stylus to power the movement of the needle. The engine was then connected to a voltaic battery of two glass jars held up by a metal stand. The most favorable liquids used are bichromate of potash and sulphuric acid(patent). The connection between the pen and the battery can be disconnected by removing metal plates inside the jars to prevent consumption of materials when the pen is not in use (Wheeler). The most important aspect of the pen is speed of the needle and movement of the needle. If the needle was not quick enough to match the speed of the hand, the paper would either tear or the stencils were not complete or legible. Although the devise is more like a sewing machine or knife than a pen, the machine had to be able to work and survive while being treated like one. Another problem was if the needle moved in any way other than up or down. If the needle became loose, the script would be messy and unreadable. The length of the wire from the battery to the pen had to be loose enough and long enough to not effect the movements of the hand. The electric pen seems to be an awkward device especially since the pen had to be perfectly perpendicular to the paper, balance a rotating electromagnetic motor on top, and move smoothly despite vibrations moving a needle up and down at 8,000 perforations every minute(Iams). The electric pen seems to be an overall dangerous machine: an open motor, batteries in glass jars in which the connecting metal plates can and are suppose to be removed when not in use, and a sharp vibrating needle sold on a mass market level and advertised as easy to use (Wheeler).

Printing

The stencil was made usually on wax paper or bond paper which could yield 5,000 to 15,000 copies and 20,000 on tracing cloth (Wheeler). According to Edison parchment did not work well as a stencil, although regular paper seems to be able to work fine for just a few copies. Once the stencil was made, the pen tracing into the paper over a thick blotter so as to not damage tables of the needle, the stencil would be laid over paper on a press that came with the pen. The press was a separate platform where the paper would be laid down and the stencil on top. Clamps were attached to hold the paper and stencil in place to ensure legibility and neatness. Using an inked felt rolling and diluted ink with oil or semi-fluid ink, the roller would run over the stencil to make one copy (Patent). One roll of ink could make numerous copies (Wheeler)

Electric Pen Improved and Remediation

The Woodbury Holder

Since writing with the electric pen was so unnatural, because no one can write at a perfect perpendicular angle, the Woodbury Holder was sold to make the writing easier. The Woodbury Holder literally held the electric pen so it was always at a 90 degree angle. "The weight of the Electric Pen rests upon the point of the tube and the small leg which projects to the right of the holder" (Wheeler). The holder or handle extends outwards from the pen and looks like and is in the position of an actual pen. By moving the pen-like handle and exerting a little pressure the Electric Pen will move as you move the handle. The displacement of the writing is similar to that of cameras in which the lens and the view finder are at different angles and must be rectified before shooting the picture. The Woodbury Holder displaces the point of writing to make it easier for beginners to use the pen and also lessen the "jar" of the pens vibrations. The Woodbury Holder was sold at 5 dollars (Wheeler).

Reed Pen

Although the Electric Pen is a writing instrument is doesn't connect words or make lines. The tiny perforations are not connected but instead made small enough so the ink will fill in the minuscule spaces. The Electric Pen is really more like a sewing machine and the words cannot connect or else the centers of the letter o's and a's and cursive letter s's will fall out. Perforations are the obvious solutions to lines so the writer does not have to pay attention to where words connect or be prohibited from writing cursive or very quickly. The Reed Pen is the solution for those who write too quickly for the Electric Pen. Developed by Edison, the Reed Pen is for the expert autographic printer. "It is not recommended, except to very fast, skillful penmen, as the speed of the pen is so great that the centres of the letters are liable to cut out" (Wheeler). The Reed Pen could be bought for 25 dollars.

Music Ruling Pen

The Music Ruling Pen came with five needles to draw measures for writing music. Similar to chalk holders that can carry five pieces of chalk with equal distance and for the same purpose but much less dangerous. The stencil paper must be places on thick cloth and two batteries are needed to make good impressions. The complete Ruling Pen was sold at 30 dollars and just the attachment, which could be used on any Eletric Pen was only 5 dollars.

Crayola Cutter

Crayola Cutter

The Crayola Cutter is the newest form of the Electric Pen but for kids and safe. The Crayola Cutter works in exactly the same way by perforating the paper, but used mainly for arts and crafts projects. Completely made of plastic, but the main parts to the Electric Pen are still there. The stylus resembling an actual pen is still used connected by a wire in which it is battery powered. The wire or string also serves the purpose of not losing the pen from the rest of the machine. The batteries are not separate and are held inside the press which serves mostly as a blotter, since the Crayola Cutter, although it can make stencils, is mainly for cutting things out. So the pen, wire, press, and batteries are still intact from Edison's original design but remediated for children. It can be assumed the speed of the needle (or cutting tool probably not a needle) moves up and down at a much lower speed. And although the function of the perforating pen-like device is exactly the same, the purpose in whic it is used is completely different. The Crayola Cuter is not a reproduction machine but a safe and sophisticated alternative to scissors.
