Gideon Sundback Zipper Facts

History of Fitst Zipper Invention-Gideon Sundback Zipper Invented

Judson Whitcomb

shoe fastener

In 1893 an American businessman Judson Whitcomb (1846-1909) has registered two "shoe fastener" investment in U.S. Patent Office: here had the idea of the zipper born. Whitcomb, as a creative mechanical and investor, has registered about 30 investments during his life.

Harry Earle

Lewis Walker

Harry Earl and Lewis Walker joined to Whitcomb and established the Universal Fastener Company in Chicago, later the Automatic Hook and Eye Company in New Jersey.

The first slide fastener appeared in 1896, made in Pennsylvania to close packages and post office sacks.

The first construction manufactured in standardised production by the Automatic Hook and Eye. It appeared in 1905. The closing parts were hooks on one side, and eyes on the other side, which were put together and took apart by a Y-shaped tensile. The parts were fixed on textile bands to fix them on textile.

When Whitcomb and Earl left the Automatic Hook and Wye, they were replaced by Peter Aronson and Gideon Sundback (both Swedish origin). Sundback's construction, the Plako worked also with hooks and eyes, but because of its lastingness and easy-handling it became more popular then C-Curity. Production flew after 1908 for many years.

In 1917 Sundback created the "Hookless Hooker", which worked without hook and eye pairs. Metal tooth were fixed on textile bands. The modern zipper has born.

Lamp No. 8 to. 10 - U.S. Patent Office Declaration of Interference, Sawyer and Man vs. Edison

Edison patent models with coiled filament made of bamboo, not carbonized, but rubbed with lamp black, made at Edison's laboratory in Menlo Park in 1881 for Edison's legal defense in the Patent Interference Declaration issued against the Sawyer and Man lamp by the Patent Commissioner on September 23, 1880.

Lamp No. 11 to 16 - Swan vs. Maxim vs. Edison

Lamp No. 17 - Swan vs. Maxim vs. Edison

Swan lamp made prior to EdiSwan collaboration by Sir Joseph Swan, circa 1884 - made for spring-clip socket invented by Joseph Swan's Chief Engineer, Henry Edmunds, see Edmunds U.S. Patent 288,217. Maxim U. S. Patent 230,310, Defendant's Exhibit, Commissioner's Decision. - Ex parte Maxim. Additional published reference, to Lamp 16 - "Edison's Electric Light, Biography of an Invention" R. Friedel, P. Israel and B. S. Finn, Rutgers University Press, 1985/87 p.194;"Evolution of the Electric Incandescent Lamp", Franklin Leonard Pope, Boschen & Wefer, 1894, p. 79.

Swan lamp, made for 1881 Paris Electric Exhibition. Only complete 1881 specimen known to exist from Paris Opera Theatre chandelier, with International Electrical Exhibition label, hand written by William H. Meadowcroft, "Swan Lamp & Socket Paris Elec. Exh. 1881 Rec'd fr. H. Edmunds 1881" of card stock with string fastener.

Company London Oct. 1881" of card stock with string fastener.

Lamp No. 20 - Edison vs. Thomson

Edison Effect lamp, earliest documented by Edison Pioneer John W. Howell, "used by Edison in 1883 in his experiments on the Edison Effect." Observing what Edison described as his "blue air" phenomena, the perplexing electrical disturbance he first discovered on September 8, 1879 became a focus of experimentation. Frances Upton wrote of this event that day, "The aluminum electrode became bright yellow in the blue light with some green phosphorescence. At one time the yellow electrode could be made to change phase by heating. It would jump over and then dance as if uncertain where to stay after the flame was taken away." Edison then created this center wire anode working model. Eminent Scientist, Sir William Preece, was not to report his own research on the "blue effect" until March 26, 1885 in which he named it the Edison Effect.

Lamp No. 21 - Cazin, F.M.F. vs. Welsback Light Co.

Edison "Graphite" lamp, made at Menlo Park, tested by J. W. Howell (opened at tip to extract sample graphite filament for test, marked February 18, 1882 (date etched on globe by J.W. Howell). Additional published reference,"Menlo Park Reminiscences", Edison Pioneer Frances Jehl© , 1936, p.374.

Lamp No. 22 - Cazin, F.M.F. vs. Welsback Light Co.

Edison "Twin Hairpin" lamp, treated bamboo carbon filaments connected in series, formed in electric resistance furnace (3,500 deg. C). Became series design to "Edison GEM" lamp (acronym - General Electric Metallized), graphite coating on carbon filament took on metal properties during electric furnace treatment.

Lamp No. 23 (not numbered) - Swan vs. Maxim vs. Edison

Open Lamp Specimen, originally from 600-light Swan Chandelier in Paris Opera Theatre, 1881 Paris Electrical Exhibition. Open lamp specimen gives a rare inside view of intricacies of Swan craftsmanship. International Electrical Exhibition label, hand written by William H. Meadowcroft, "Swan Lamp Buffet, Paris Elec. Exh. 1881, Rec'd fr. H. Edmunds 1881" of card stock with string fastener.

Two Jeweler's Loupes

Both loupes were found at the bottom of the wooden box. One is a moulded ebonite bell loupe, with early repair made of brass wire. The other is of ivory of curved cylindrical form with a recessed lens. Both were used no doubt by Howell and the court to examine Edison's Tar-putty lamp filament Exhibits.

William Henry Meadowcroft

Notary for the Court, New York Southern District, signed in countless exhibits for Edison Infringement trials, also conducted and notarized depositions throughout the proceedings. Later, after trials, became Edison's life long personal secretary and publicist, coauthor of biography, "Edison, His Life and Inventions" New York: Harper & Bros., 1910.

Henry Edmunds, Jr.

British engineer, met Edison in 1877, became Edison European associate, became partner in Swan electric lamp development in 1881, Edmunds designed and installed Swan Opera House Chandelier at Paris 1881 Electrical Exhibition, patented Swan lamp hook socket in 1883 - U.S. Patent 288,217.

First Electric Light Bulb--(Thomas Edison light bulb)

First Electric Light Bulb--(Thomas Edison light bulb)

Thomas Edison presented his first light bulb in 1879 (U.S. Patent 223,898 - there were many disputes about this*) and it's been improved upon and made more efficient ever since. But while the efficiency is welcome, there are now beautiful reproductions - called Edison Bulbs - that are perfect for some decorative uses and low light areas...

First Electric Light Bulb--(Thomas Edison light bulb)

For example, the lamp above I saw in the window of Michele Varian this morning. The bulb has a cool effect in that you can look right at it and see the fragile filament without hurting your eyes. The best feature is the simple loops of filament. There were (and are) a lot of styles, and some are still made with carbon filaments (Edison's was a bamboo filament).

First Electric Light Bulb--(Thomas Edison light bulb)

I use these with vintage lamps and have seen them used to great effect in bars and restaurants where they add a low warm glow and a vintage feeling. Because of their old fashioned construction, they are NOT efficient and you should know that up front. They can put out 25 watts of light while using 60 watts of electricity, but used sparingly that shouldn't be a big deal.

I put together a list of sources as well as the history of these bulbs down below. Check them out. If you ever want to spiff up an old lamp or do something special where changing the light bulb is your only solution, this is a great arrow in your design quiver.

First Electronic Computers Invention in the World

in Computers, First inventions, General informations

Taking calculations of 5,000 addition-subtraction, and 340 multiplication was considered to be a big marvel in the past. For nearly 3 years of researching and manufacturing, the first electronic computer, ENIAC I was first introduced at the University of Pennsylvania's Moore School of Electrical Engineering in 1946. The research forENIAC I, Electrical Numerical Integrator and Calculator, was developed by John Mauchly along with John Presper Eckert and sponsored by the American military. The ENIAC I, also seen as a "Giant Brain", contained inside 17,468 vacuum tubes, 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. Costing $480,000, the ENIAC I has its floor space of 1,800 square feet and the weight of 30 tons. Let's take a look at the most wonderful images of the first electronic computers in the world including the ENIAC I.
