The Mayer-Osborn elevator in Tempe, Arizona is a jewel in an upscale setting

Phoenix is well out of the way for a pilot based in Louisville, Ky., and living in the Chicago area. It takes a bit of intentional finagling to get into Phoenix with enough time to visit an elevator. Fortunately, the Mayer-Osborn grain elevator in Tempe sits at the foot of a hill, just a few miles off the end of an active runway at Phoenix Sky Harbor International Airport. A steady stream of airplanes flies directly over the elevator, either coming from, or going into the airport, depending on the wind conditions. After seeing it many times from the air, I arranged for a four hour layover in Phoenix, which was just enough of an opportunity to grab a rental car and go see it.

Manhole covers are embossed with the company name. Each annex bin has a manhole cover.

The straight-up styled elevator with its annex was built in 1951 for the Hayden Flour Mill, a Tempe landmark which had already been in operation for decades.  It once proudly displayed the “Hayden Flour Mill” name, painted along the annex side, in lettering that has been painted over at least twice. The white paint has now faded enough for both lettering jobs to show through.

Hayden Flour Mill

 

My dad,  Jerry Osborn, remembers when his father worked the Mayer-Osborn job in Arizona. Dad would have been about seven years old. The job was one of many that took Bill Osborn away from his home in Fremont, Neb.

The Mayer-Osborn elevator and annex nestle at the base of a hill, gracing the neighborhood like a white gemstone in a gleaming setting. The Hayden Flour Mill, which has a strong historical significance to the area, is a rather unremarkable looking building, located at the base of the elevator. The neighborhood has grown up around it with shining highrises, shops and hiking trails, erasing the former industrial setting, and replacing it with an upscale ambiance.

It is fortunate that the mill and elevator add character and personality to the place, and that city planners have recognized their value. Now a park and lawn surround the mill. The mill’s windows have been screened so that tourists can look inside, and historical plaques detail its history. The elaborate plans for the mill have been put off after the market crash in 2008, but fortunately the goal of preservation has not been abandoned. It is good to see one of my grandfather’s elevators safely ensconced in a community that values its presence.DSC_0030

Concrete problems plagued consecutive elevator projects at Blencoe, Iowa

by kocart

DSC_0578Story and photos by Kristen Cart

In the summer of 1954, Mayer-Osborn Construction built an elevator with a stepped headhouse in the northwestern Iowa town of Blencoe. As my dad, Jerry Osborn, explained, after the crew poured the first ten feet of concrete in the slip-form process, the concrete sides below the forms showed signs of crumbling. An investigation revealed that the concrete mixture had not been set correctly. It took as many hours to remove the concrete and start over as it did to pour it. Dad worked on the project and saw the fallout first hand.

Builders were required to do a destructive test on the concrete mix at various stages of curing, to ensure the proper strength for each part of the elevator structure. Engineers tested various mix ratios to decide upon the best one. Naturally, this process was used at Blencoe, but when the mix was finally set and the pour began, it was done incorrectly. I can imagine the blue language wafting from the site as the concrete was taken down. Someone on the site had his ears pinned back pretty fiercely. But the construction continued, and a handsome elevator still stands there today, nearly 60 years later.

Not until this year, when Tim Tillotson located the Tillotson company records and photographs, did we discover that Tillotson Construction of Omaha faced a similar problem as they built their elevator nearby about a year later. This time, the error was not caught as early, and the consequences became immediately apparent.

Tim Tillotson said he thought the blowout happened in about 1955. Whether Tillotson Construction did the repairs and completed the project, or whether another contractor was brought in, is not known to me, but I hope to revisit the site later this year and learn more. The image below is a rare one. It is amazing that photographic evidence survived, serving as a cautionary note, lest any builder were to become overconfident.

This company photo shows the blowout. On the right the completed Mayer-Osborn elevator may be seen.

Errors were a constant threat in this business. In the best cases, they manifested themselves in embarrassing delays, in the worst, they incurred expensive lawsuits or physical harm.

Tillotson Construction and Mayer-Osborn both recovered from their respective forays into bad concrete and lived to build again, leaving handsome and serviceable elevators at Blencoe and elsewhere. The lessons they learned were priceless.

A chance encounter with a Tillotson elevator in Jamestown, Kansas

Sporting a fresh coat of paint, the trademark Tillotson elevator with its curved headhouse still operates. 

Story and photos by Kristen Cart

On our last elevator road trip, which our family embarked upon in October 2012, we visited many of our grandfathers’ elevator projects from the 1940s and 50s. But we also amassed a photo collection of elevators we could not place. Either the grain cooperatives were closed for business on a Sunday, or the elevators were retired, or we didn’t have time to stop for an interview. So the photos languished for most of a year, until Ronald Ahrens and I could identify them, even though we strongly suspected that the structures were the works of one of our grandfathers.

One of the mystery elevators was a pure white example, located in the north-central Kansas town of Jamestown. Ronald’s uncle, Tim Tillotson, recently handed us the Omaha builder’s construction specifications, which finally identified this handsome elevator as a project built in 1953 by the Tillotson Construction Company.

A smaller elevator stands on a branch of the rail line. It's builder is unknown.

A smaller elevator stands on a branch of the rail line. It’s builder is unknown.

The Jamestown elevator stands not far from a companion elevator, rising alone on a fork of the railroad track. The smaller elevator was built in a straight-up style that predates the more common Tillotson style, and it’s provenance is unknown. It is reminiscent of the style of the elevator built by Tillotson Construction in Greenwood, Neb., but without the curved headhouse. But it also recalls several Chalmers and Borton examples.

It is our good fortune to have the detailed specifications for the Jamestown elevator.

The construction record was written with painstaking attention to detail.

The construction record was written with painstaking attention to detail.

Our friend Linda Laird has asked if the Tillotson Construction Company’s records included any Kansas elevators. The answer is yes, and here’s an example.

In 1948, Tillotson built an elevator of reinforced concrete at Moscow, in the extreme southwestern corner of the Sunflower State. The plan’s basic aspects were as follows: four tanks of 14 feet in diameter, 120 feet in height, and an eight-foot spread. The driveway was was 13 x 17 feet and there were six bins over the drive. Another notation says “Ext. to roof.” This shows up on most other plans and is supplemented by “1/2 grain” or “for grain.” The final item at the head of the plan’s entry in company records notes “13 bins & dust bin.”  Here are all the data:

Capacity per Plans (with Pack) 100,000 bushels

Capacity per foot of height 1033 bushels

Reinforced concrete/plans (Total) 1070 cubic yards

J. H. Tillotson, Contractor, built their elevator scale houses with distinctive flair

Elevator construction was driven by stringent engineering requirements, lending a degree of commonality to the buildings. A few distinguishing details could be noticed, but from a distance you would be hard pressed to determine the builder. When contractors built the accompanying buildings, however, they had free reign to build in a style they could call their own. Often the scale houses would be instantly recognizable.

J. H. Tillotson’s designs lent themselves well to the addition of a stylish scale house built alongside the main elevator. In some cases, when visiting an elevator, our access was limited. Then the lines of the scale house would be the only clue that we were looking at a J. H. Tillotson elevator.

Below are a few examples, each adapted to its individual setting, but each showing some distinguishing details that were common to all. Each J. H. Tillotson scale house was built of concrete, with a rectilinear floor plan. Usually they incorporated a protruding bay window, on the side facing the scale, for added visibility. Stairs, usually with steel railings, led to a door to accommodate truckers’ entry into the building. Carefully executed details in the concrete expressed the architect’s personal sense of style.

While the builder of the elevators at McAllaster and Bradshaw has not been established with certainty, a fair case can be made that they were J. H. Tillotson designs based on details of the elevators themselves, the driveways, and the scale houses, when compared with known elevators. The scale house at Daykin, Neb., is included here for comparison.

J. H. Tillotson’s designs were visually appealing, with scale houses that contributed to a harmonious whole. When considering a builder, buyers would judge the quality of the elevator by its beauty, among other things. In this regard, J. H. Tillotson, Contractor, was more successful than most.

An often unnoticed feature of every grain elevator is the scale house. The scale house is home to the cooperative site office, and is the place where the elevator conducts its primary business. It is usually an unassuming building where empty grain trucks pull up to be weighed before filling up. The trucks make a second visit when laden with grain, and the difference in weight is tallied in the office. Conversely, when a full grain truck pulls up to deposit its grain, it must return after unloading to determine how much has been loaded into the elevator. Inside the scale house, a small sample of the grain is tested for quality and moisture content.

Many scale houses are metal or brick buildings, often unattached to the elevator and some distance away. Most are  unremarkable. But some of the old concrete scale houses have unique charm. The scale houses that accompanied J. H. Tillotson elevators were particularly attractive, and are one of the first things to look for when identifying their elevators.

Other builders also produced some remarkable scale houses. Elevator building was driven by engineering and economical constraints, but in some cases the scale houses received special attention. In Willows, Calif., I photographed an example that had to take first prize. This dandy building recalls a 1960s drive-in burger joint, complete with car-side speakers and root beer floats. While it is not an example of our grandfathers’ work, it deserves notice.

Joseph H. Tillotson developed a characteristic style for the scale houses his company built. Those I have visited appeared to be concrete, and many had attractive details. For more typical examples of his work, stay tuned.

Jim Sheets (’bout half Native American)

Everett Glen (Chas & I concur Everett was the super on Flagler, Colo., in 1953; I had told you before that Mother found him dead in his car in the parking at the house where he was working on finish trim, cabinet work, et cetera; this unfortunate incident had to be fall or winter of ’53 after the job in the summer.)

Painting an elevator meant ‘swing time’ on a flying scaffold in the wind

by baggyparagraphs

Scan

By Ronald Ahrens

This photo from the Tillotson Construction Company archives shows two painters on a flying scaffold at an undetermined elevator.

The following passage is by my Uncle Merle Ahrens, who recalls spending the summer of 1955 with my Uncle Mike Tillotson, painting elevators in Nebraska:

When Michael and I started work, all the concrete pouring was complete and we were given the task of painting the outside of the whole elevator. We painted it using a lime-base whitewash.

We had to crawl over the edge of the top of the tank onto a flying scaffold. The scaffold was held up by a pair of rope block-and-tackles connected to a pair of wood beams that were extended about two feet over the edge of the tank. The wood beams extended about ten feet inboard and were weighed down with sandbags to keep the scaffold from falling. The scaffold was made up of a pair of two-by-twelve boards with a metal frame at each end and two-by-four railings around it. The rope block and tackles were attached to the scaffold on the ground. We had to pull the scaffold up to the top every time for each ten-foot width we painted.

There was an old man on the ground who mixed the paint and pulled it up to us in a five gallon bucket. He had a harder job than we had. All we had to do was brush on the paint and pull the rope to release the half hitch that held up the scaffold and let gravity work to lower it. The “flying” part of flying scaffold was when the wind was blowing. You would fly halfway around the tank.

Merle at home

Merle Ahrens in 2011 at his home in Titusville, Florida.

Every night we would take off our Levi’s and stand them in a corner. There was so much paint on them! Yet one pair lasted all summer.

After a couple of months we finished painting the elevator in Lincoln and went to David City to paint another grain elevator. This time we used a new latex paint. It was very slow-drying and the wind kicked up a lot of dust. The elevator ended up white with grey stripes.

We kept hearing of accidents at other sites. One man [Larry Ryan]was said to have fallen from a plank used to walk between the tops of two tanks. He was wearing new boots and slipped.

Another was killed when roofers removed the sandbags holding the beam for the flying scaffold so they could hot-tar the roof.

A couple more were hurt while riding on a bucket and the clamps holding the cable slipped. The clamps were installed wrong.

I do know for a fact that one worker at Lincoln was hit in the face when a five-gallon bucket with concrete in it fell while he was using a rope and pulley to lift it overhead.

Uncle Tim Tillotson recalled the challenge of painting while the scaffold flew back and forth in the wind. “When you’d come back you’d get a few licks in with the brush,” he said.

A photography outing reveals beauty at the Mayer-Osborn elevator in Byers, Colorado

A documentary photograph of the Byers, Colo. elevator.

In the fall of 2012, Gary Rich, contributor to this blog, treated me to a photo tour of western Colorado elevators. I made a special stop to meet Gary and his wife Sandy. The last few years Gary has specialized in elevator photography, capturing the beauty and spare elegance of grain elevators, identifying their builders as he went. The Byers, Colo., elevator is one of the loveliest.

DSC_0212

Gary Rich, camera in hand, looks for a better shot.

Sandy Rich is a very good photographer in her own right, and she has challenged Gary to greater creativity in his compositions.  He explained how her inspiration led him away from “documentary” shots and toward more artistic photography. When we stopped at Byers, Colo., we took some of her ideas to heart, and we were very pleased with the results.

Mayer-Osborn construction built the Byers elevator in 1950, as noted in a contemporary newspaper account. My father Jerry Osborn remembers his dad William Osborn working on it.

DSC_0205

Using the foreground to frame the subject adds interest to the photograph. Gary shot this composition first as can be seen on his photo site.

Retaining some of the characteristics of the earlier J. H. Tillotson elevators, the Byers elevator recalls those at Traer and Hanover, Kan. The Byers elevator is bigger than the Hanover elevator, and you can see where design adjustments accommodate the greater volume. The windows are very similar to those at Traer. The manhole covers on the exterior at Byers represent an innovation to fulfill local needs.

Since elevator designs continued to improve over time, an elevator design genealogy becomes apparent. The innovations cross company boundaries and are seen by looking at elevators chronologically, especially where the same builders and architects continued working in the business, bringing their ideas to one company after another. This is a chronology we are still trying to understand.

As we strive to understand elevator history, we take pictures. Elevators are worthy of our understanding and preservation for their beauty, not just their utility. Beautiful photos convey that message in a way that words can never express.

The manhole covers on the exterior of the Byers elevator identify Mayer-Osborn as the builder.

Despite ADM’s ‘No Admittance,’ the mystery of Moscow is solved

by baggyparagraphs

Elkhart 189 copy

Story and photos by Gary Rich

I spent a couple days during October 2012 photographing grain elevators in southwestern Kansas. Arriving in tiny Moscow, Kan., I saw a concrete elevator with a curved headhouse and had a hunch it was built by Tillotson Construction Company.

My problem was that it was operated by Archer Daniels Midland. ADM has a strict policy of not allowing anyone on their property. I went inside and had a conservation with the elevator manager. I didn’t have any hope getting into the elevator. He told me that it was built by Chalmers & Borton. I knew this was not the case, since Chalmers & Borton never built an elevator with a curved headhouse. He told me I could take all the photos I wanted. However, it would be across the street from the elevator.

I have wondered since this trip how I would ever find the true builder for this Moscow elevator.

Elkhart 207 copy copyabThe recently discovered records of Tillotson Construction Company show that Tillotson indeed built this elevator in 1948. Capacity was 100,000 bushels with 14 tanks and a 13-foot-wide center driveway. Six bins were over the driveway.

The Moscow elevator was a very small one for anything made of slip-formed concrete. Tillotson built another relatively small elevator in Rolla, Kan., that had a 140,000-bushel capacity. Most that Tillotson was building in this time frame were of 200,000-bushel capacity or even larger.

The Santa Fe Railroad had a branch line from Dodge City, Kan., to Boise City, Okla. It was about 140 miles in length. Tillotson Construction built elevators in Ensign, Montezuma, Satanta, Moscow, Rolla and Elkhart, Kan.

It’s  quite an accomplishment that Tillotson built six elevators along this line.
