Davenport Inventors

Many of us don’t often think about how everyday objects came to be: washing machines, zippers, fire escapes, even the board games we play. But behind them all is a person with an idea.

Davenport citizens have been responsible for a startling number of those ideas over the years. The Iowa Inventions Database lists 5,412 patents in Scott County between 1843 and 2009, 4,103 of them in Davenport alone. And it’s useful to keep in mind that these are only inventions that have been patented. Obtaining a patent is usually a long and expensive process involving attorney fees, so our information is limited to those with the financial means to file for one.

Some of the following inventions created by Davenport residents are imperative to safety, some are strange, and all are useful.

Fires were common in the 19th century, so much that the Peterson Paper Company was constructed to be “fire-proof.” The following Davenport inventors were attempting to improve the safety of fire escapes for their fellow citizens.

Heuermann, John. “Fire Escape.” US 96,698, United States Patent and Trademark Office, 9 Nov. 1869. Google Patents.

John Heuermann’s 1869 patent for a fire escape that could be wheeled to the aid of those needing rescue. Wheeled fire escapes existed at the time, but Heuermann claimed his to be more stable so that the escape would “stand plumb.”

Wahle, Lorenz. “Fire Escape.” US 105.280, United States Patent and Trademark Office, 12 July 1870. Google Patents.

Lorenz Wahle’s similar design (1870), this time employing a “screw power for operating the…jointed frame and ladder.”

Schroeder, Nicolaus. “Fire-Escape.” US 200,878, United States Patent and Trademark Office, 5 Mar. 1878. Google Patents.

In 1878, a patent was granted to Nicholaus Schroeder for improvements on this type fire escape, which allowed people to attach to an object in the room by way of a rope and lower themselves to safety on this seat. In the patents, Schroeder claims that the novelty of his invention lies in the stability of its construction.

 

Werner, Minnie. “Adjustable Cooking Pan.” US 1,202,629, United States Patent and Trademark Office, 24 Oct. 1916. Google Patents.

Other inventions improved the design of everyday objects. Minnie Werner, a housewife, patented this adjustable cooking pan in 1916. It was made to prevent the dressing from getting soggy and could be placed in the oven directly in the juices from the meat. You could also adjust it to create a cake of many sizes. For cleaning, it could be easily disassembled and flattened for convenient storage.

Rohwedder, Otto F. “Machine for Slicing an Entire Loaf of Bread at a Single Operation.” US 1,867,377, United States Patent and Trademark Office. 12 Jul. 1932. Google Patents.

The Quad Cities is famous for the invention of sliced bread. You may know that Davenport’s Otto Rohwedder invented the bread slicer, but his idea sparked a succession of improvements and alternate versions by local inventors, including Harry J. Criner (1933), Arthur A. Kottman (1934), William E. Bettendorf (1934), Taylor Creech (1936), and Charles H. Petskeyes (1947).

Criner, Harry J. “Bread Slicing Machine.” US 1,925,481, United States Patent and Trademark Office. 5 Jan. 1933. Google Patents.

While Rohwedder’s invention featured slicing bands, Criner’s introduced blades to improve the uniformness of the slices.

Kottman, Arthur A. “Control for Bread Slicing Machines.” US 1,964,824, United States Patent And Trademark Office. 3 Jul. 1934. Google Patents.

Getting the conveyor belt and the blades to act in concert with each other was a challenge for inventors. Kottman’s control for these machines only allowed the conveyor to run if the blades were working at their intended speed.

Bettendorf, William E. “Blade Frame Assembly for Slicing Machines.” US 1,968,020, United States Patent and Trademark Office. Google Patents.

William Bettendorf’s blade frame assembly fixed the problem of differing blade tension, which often resulted in a wavy slice,by incorporating nuts and bolts that allowed operators to adjust the tension by small degrees.

Petskeyes, Charles H. “Bread Transferring Means for Bread Slicing Machine.” US 2,417,782, United States Patent and Trademark Office. 18 Mar. 1947. Google Patents.

Petskeyes’ bread transferring means employed “follower bars” on a chute to hold loaves of bread steady as they traveled through the conveyor.

Creech, Taylor. “Bread Slicing Machine.” US 2,056,134, United States Patent and Trademark Office. 29 Sept. 1936. Google Patents.

Since timing and position was everything when it came to bread slicers, Creech invented a machine that improved these in some of these ways: by arranging the conveyor and feed table to “cushion” the bread while it travels through the blades, ensuring uniform slices; by feeding the bread to the blades at an angle to  “prevent crushing”; and by the use of a mechanism that held the slices together before they were wrapped to ensure that the loaf would not be crushed or fall apart.

 

The Davenport Democrat and Leader, 25 Jul. 1933, p. 6.

You may recognize the Clapp surname from this blog about Lottie Clapp, the first female funeral director in the tri-state area. Her son, Alan, only owned the funeral home for a short while after his mother’s death; however, he did contribute to inventions in the funeral industry.

Clapp, Alan. “Embalming Implement.” US 1,825,993, United States Patent and Trademark Office. 6 Oct. 1931. Google Patents.

His patent for a multi-directional embalming tool would “do away with the necessity of removing the instrument from an artery and then turning it end for end.”

The Daily Times, 17 Mar. 1951, p. 5

Much later, in the 1950s, Edward J. Lager invented a burial vault that claimed to prevent decay. This is just one of the examples of funeral industry scams that were brought to light with the 1963 publication of Jessica Mitford’s The American Way of Death.

 

Evins, Dossa D. “Diagnostic Instrument.” US 1,648, 939, United States Patent and Trademark Office. 15 Nov. 1927. Google Patents.

Some inventions, however, were extremely useful to their industries. Although his most famous invention was the neurocalometer, a device for detecting changes in temperature along the spine, Dossa Dixon Evins invented several chiropractic implements during his life, including an adjusting table and a method of creating x-rays.

There are many, many more local inventions where these came from. If you’re interested, visit the Iowa Inventor’s Database.

Timelines for Genealogy

This year’s Quad Cities Genealogical Conference will be on Saturday, April 27th from 8am-4pm at the Stoney Creek Hotel & Conference Center in Moline. One of the topics that will be covered by speaker Beth Foulk of Genealogy Decoded is “Solving Genealogy Problems with Timelines”.

Timelines help you get a better understanding of what life was like for your ancestors. You can see all of the important events in their life in order. If you add major world history events to your ancestors’ timelines, you get a sense of historical context. 

Timelines also help organize your research. When you lay out your ancestor’s life using a timeline, you can easily identify where you have gaps in your records and if you have conflicting information from different sources.

To prepare for the conference, we looked up the many newer Apps and websites that take your family tree data and display it as a Timeline. 

We chose Twile because it is free, easy to use, and you can collaborate with other family members or researchers. You can import your tree data from FamilySearch, a gedcom file, or start from scratch. 

You start by adding your information, then it takes you step-by-step. You can upload photos from your computer or import photo albums from Facebook. In this example, we uploaded images from vital records, census records, and family photographs.

      

Not only does it display your data in a timeline form it also displays a traditional Ancestor Chart. This is where you add more relatives and invite living family members to view and collaborate on your timeline.

Each person in your tree gets a profile where you add “milestones” in your ancestor’s life. In this example, I added my grandparents’ marriage with an image of their marriage license. 

 When you specify the place an event took place, Twile adds information from Google Maps. There is also a place to add other relatives who were present at that event.

Use “Streams” to add historical events to your ancestors’ timeline. See who was president when your ancestors were born, or what important invention was made during their lifetime!

 

You can also view your family tree data in an infographic:

 

Have you been using timelines for your research? Which programs have you tried? Or do you prefer writing it everything out on paper? Let us know in the comments!

Happy National Chocolate Candy Day!

We came across information that today, December 28th, is National Chocolate Candy Day. We aren’t sure how it started or who started this event, but we thought why not celebrate with advertisements from the past.

This store seemed to have all holiday treats, including chocolate, in stock for Christmas and New Year’s Eve 1857.

The Morning Democrat, December 29, 1857. Pg. 2.

We are not sure how iced chocolate jelly balls were made in 1890. They would probably be refreshing on a warm summer day. Roddewig-Schmidt Cracker Company was formed in Davenport in July 1887. Soon after it began a confectionery branch that evolved into Roddewig-Schmidt Candy Company. The candy company was a leader in locally made chocolates until it closed in 1928.

The Davenport Democrat, May 8, 1890. Pg. 1.

We thought this advertisement captured the feeling of the holidays.

The Davenport Democrat, December 23, 1898. Pg. 3.

Krell Confectionery was one of the oldest confectionery businesses in Davenport when a fire destroyed the store on Brady Street in May 1921. In September of that year, owner J.W. Krell decided not to reopen the Davenport store; keeping only his Rock Island store in business.

The Davenport Democrat, December 28, 1900. Pg. 5.

In the early 1900s, the Roddewig-Schmidt Candy Company introduced the Davenport made Velma and Minerva chocolates. The Minerva chocolates were only produced in the sweet chocolate form while Velma Chocolates were produced in sweet, bitter-sweet, and milk chocolate varieties. 

The Half-Century Democrat Special Edition, October 22, 1905. Pg. 62.

Of course, baker’s cocoa and chocolate were sold for those who desired to make their own candies at home.

The Daily Times, December 30, 1905. Pg. 3.

Advertisements may change in design, but the message seems to stay the same. 

The Davenport Democrat and Leader, December 16, 1913. Pg. 9.

Don’t worry if you indulge a little to much after reading these advertisements. We found out that December 30th is National Bicarbonate of Soda Day!

Wishing you all a Happy New Year.

The World War II Homefront: A December test

While researching an upcoming blog, we came upon a reminder of life during World War II in Scott County we wanted to share with you.

The evening of December 14, 1942 was important for people living in the State of Iowa along with North Dakota, South Dakota, Nebraska, Minnesota, Missouri, Wyoming, Colorado, and Kansas (nine states encompassing the Office of Civilian Defense’s Seventh Service Command Area). All persons living in these states were to participate in a 20 minute mandatory test blackout of all lights starting at 10:00 p.m.

Blackout and Air Raid protection fell under the Office of Civilian Defense, an emergency war agency, which was created by Executive Order on May 21, 1941. Locally, the City of Davenport passed Ordinance 7832 on September 2, 1942:

An Ordinance authorizing blackout and air raid protection orders, rules and regulations: prescribing penalties for violation thereof: and declaring an emergency.

The Daily Times, December 14, 1942. Pg. 22

This first blackout was promoted as an official practice. All further test blackouts held would be a surprise to the community.

Newspapers outline what individuals were to do if they were driving or at a place of business instead of home. The War Production board had already asked citizens to not use outdoor Christmas lights to conserve materials and energy so there was no worry about turning off outdoor decorations.

The Davenport Democrat and Leader, November 8, 1942.

Boy Scouts and civilian volunteers practiced and participated in the blackout when the air raid sirens began at 10:00 p.m. Police, fire, and hospital personnel were in place and any non-emergency vehicle pulled to the side of the road and turned off all lights as only emergency vehicles were allowed to drive. Even coasting on designated streets was cancelled by the city that night as it was too dangerous for children to be sledding as cars were driving with no lights.

The next day, newspapers reported the blackout test was a great success. In downtown Davenport the only mishap was an electric sign that had not been turned off when the business closed earlier in the evening.

The Daily Times, December 15, 1942. Pg. 15

There was one sign of normalcy we noted from the newspapers on December 14th. The Capitol Theater informed local citizens that business for them would go on as usual, but to make sure they prepared their homes for the blackout before coming to the movies. 

The Daily Times, December 14, 1942. Pg. 5

Davenport’s Mary Solbrig: Believed to Be the Nation’s First Female Airplane Mechanic

In the early 20th century, The Pioneer Era of aviation began. The first powered airplanes were taking off, and men and women wowed large crowds at fair exhibitions with their flying machines.

Sunday Times-Democrat, 7 Aug. 1960, p. 40.

Among them was Davenport’s very own Oscar Solbrig. A German immigrant and bicycle shop owner, his first forays into flight involved “powered balloon experiments” and were performed around 1900. Solbrig then attended flight school and began constructing his own planes. After winding up in the Mississippi river while testing a “flying boat” (a craft that was meant to take off and land on the water), Solbrig turned to building land-based planes only. With the salvaged engine and other parts from the flying boat, a plane took shape in the attic of the Solbrig home.

According to several clippings from the Davenport Democrat and Leader, between 1913 and ‘14 he made a flight over the city that was witnessed by many awestruck spectators. From then on, the plane was used for fair exhibitions from 1914 to 1916. Solbrig’s flights were so popular that the Democrat and Leader quoted him as saying, “At the What Cheer Fair … the crowd of 10,000 was so anxious to see the machine and the flying that they crowded around the aeroplane so close it took us about 30 minutes coaxing to get the people back far enough to give me room to start.” Many had never seen such an invention before and fewer understood its mechanics.

Flying was also a dangerous business. Many aviators were killed or seriously injured in their efforts to take to the sky. Solbrig himself had several close calls; besides his aforementioned swim in the river, he also once became entangled in a willow tree and fell over 100 feet. But he only ever sustained severe bruising from these accidents, retiring from flight before the 1920’s. He lived to be 71, and over the course of the years, several articles were run about his “barnstorming days” and the preservation of his plane in Midwest museums.

Mary Solbrig upon her election as president of the Mothers’ club. The Daily Times, 5 Jun. 1936, p. 10.

But this is not the full story of Oscar Solbrig. Behind his success– every step of the way– was his wife, Mary, the woman known to be the first female airplane mechanic. She was not entirely erased from the picture while Solbrig was performing at fairgrounds, appearing momentarily in several articles during that period. Solbrig always managed to keep the press informed that Mary was instrumental in his flights, but the focus was always on the person in the cockpit.

Mary’s history as a mechanic began when Solbrig owned his bicycle shop. In her memoir about her parents, her daughter, Hope, recalls the prejudices her mother faced as a woman interested in a predominantly male trade. While Oscar was out for the day, Mary would would stay to watch the business. Hope recounts one interaction with a customer as follows: “A man came in to have a saw filed. He didn’t want to leave the saw when he saw [Mary] was alone. He wanted ‘the man’ to do the job. She told him he would get a good job or he didn’t have to pay. Well, my mother did the filing.” But Mary often rose far above expectations. Hope states that, “Somehow, he found out that she did it and after that, every time he came, he asked for ‘the lady saw filer’ to do it because he liked the job.”

Soon, Mary was assisting with the construction of Oscar’s first plane, which would eventually have to be disassembled, shipped in boxes via train, and reassembled by Mary at various fairgrounds. She became so familiar with the machine that, with her son, Alfred, helping with the heavy pieces, she could reassemble it in four hours. Besides performing any repairs to the machine, Mary faced the dangers of guarding it from eager spectators who had never seen a plane before. She recalls getting only four hours of sleep during fair season, and none at all the night before an exhibition. She and her son often camped out in the shipping boxes that housed the plane’s parts.

The Daily Times, 28 December 1954, p. 1.

The flimsy wire that was set up to keep the crowd at bay was often useless. Hope recalls a moment in the dead of night when a man ducked under it, only to be interfered by Mary brandishing a hammer. In Hope’s words, “He scrammed fast.” Her duties also included negotiating with fairground managers who were ignorant about the plane’s mechanics and often neglected to provide enough space for the plane to take off (some expected the craft to rise directly off the ground). Mary was often seen filling in rough patches on the runway with dirt she kept in her apron, and it was she who signalled to Oscar with a white handkerchief that the plane had enough power to take off. She knew it so well that she could judge by the sound of the engine.

The Des Moines Register, 23 May 1948, p. 31.

In 1948, several years after Oscar’s death, an article in the Des Moines Register discussed Mary’s role in his success. It highlighted some of the more dangerous elements of aviation in the early 20th century and showed Mary’s keen awareness of the crowd’s darker desires. “‘They didn’t come to see the airplane fly,’ she asserted in this article. “‘They came to see the flier killed.’” And there is evidence to attest to this: people often attempted to tamper with the craft before its flight, and once, someone succeeded in cutting a cable attached to the tail unnoticed. Although the pilot escaped unhurt, it cost the mechanics over a month of repairs.

Mary herself was a victim of the crowd’s wish to witness injury. During one landing, she noticed the wind directing the plane into a terrace and hurried to get a hold on part of one wing to redirect it. She reflects that “one of the spectators protested to the fair superintendent’” about her competence. “‘He said he had come “to see the airplane drag the woman” and felt shorted on his entertainment.’”

But while she actively participated in this risky lifestyle, Mary was also a wife and mother of three children. In addition to all the housework and cooking, she was elected president of the Mother’s club in 1936.

When she passed away on December 28, 1954 at the age of 85, she had seen many advances in aviation. She was honored at her funeral by local aviators, who tossed flowers from their planes.

Turkey Notes 2018

We cannot believe it was ten years ago on this date that we published our first Turkey Note blog!

Our blog, and many Thanksgiving tables, would not be complete without this local tradition.

Our co-worker, Sarah, gave the best explanation for Turkey Notes way back in 2008. We invite you to read that original blog here.

Ten years later and the origin of Turkey Notes are still a mystery to us. We think that might just be part of the fun.

To look at more Turkey Note blogs, we invite you to search using the Keywords: Turkey Notes or Thanksgiving in our search box.

We hope you enjoy our staff donations this year and, as always, we love to hear your family traditions with Turkey Notes.
