Trying to trace the sweep of Tillotson’s hand in Dalhart, Tex.

by baggyparagraphs

By Ronald Ahrens

IMG_9022Tillotson Construction Co. had yet to perfect its signature style of the curved headhouse when it first built in Dalhart in 1947.

Before the late 1940s the headhouses were rectangular with a sort of molding, of concrete, extending up the full height at each corner. 

In ’47, Tillotson built a 150,000-bushel, single-leg elevator along the busy railroad tracks of this market center, the seat of Dallam County.

In specifications it adhered to a unique plan with four tanks, or silos, each measuring 20 feet in diameter and reaching 120 feet in height. There were eight bins. The attached driveway was 13 x 16 feet.

The surprise is that Tillotson built a 98,000-storage annex in the very same year. Notes in the company records show two tanks of 25 feet in diameter reaching a height of 120 feet.

A further note says “Direct spouts from elev.–Gravity flow to Elev. Pit. Ring footing 3 bins.”

When I visited last month, I hadn’t realized there were two elevators. Maybe I missed something. I think I paid a call to the 1949 job.

Here’s what Uncle Chuck contributes: “I remember Dad having to make a number of trips to Dalhart, but if the annex was finished in ’47, like you say, then he must have been there to close out and inspect the finished project.

“My recollection was that the job was either finished or in the final punch-list stage. But like you on your trip, we had visited a bunch of jobs or prospective jobs before we got to Dalhart.

“Also, my young mind in those days wasn’t necessarily concentrated on the job status in each stop but probably more interested in the secretarial staff!”

At last he reveals the truth!
IMG_9016

Except for a railroad employee familiar from down the road in Hartley, no staff–and especially no secretaries–could be located.

Looking through the scale-house window, I saw a plate of uneaten food and an open bag of chips on the counter. Yes, another mystery.

I would leave Dalhart with more questions than before my arrival.

In Hartley, Tex., the Tillotson elevator keeps good companions in a big operation

By Ronald Ahrens

The elevator at Bushland was the third of 10 Tillotson jobs I intended to visit in the Texas Panhandle. It was still midmorning when I hightailed it out of there, heading 58 miles north and a little west through the rolling scrub country of Potter, Oldham, and Hartley Counties.

Texas-Okla Logo 04The next destination was Hartley, a town of about 500 people where U.S. 385 meets U.S. 87. Tillotson Construction Co., of Omaha, built a twin-leg, 300,000-bushel elevator here in 1950.

Like several others that year–Rock Valley, Iowa; Burlington, Colo.; and Canyon, Tex., where I had been at sunrise–Hartley was built on the Bellwood, Neb., plan. This entailed eight tanks, or silos, measuring 20 feet in diameter and here reaching to 115 feet in height. (Bellwood itself had 120-foot silos.)

IMG_8972Schoolchildren were at recess as I drove through side streets looking for a good view of the elevator. 

Arriving on the scene, I found a big operation. Of course I had recognized the Tillotson elevator’s curved headhouse. This elevator, as it turned out, has a substantial storage annex that likely more than doubles capacity. And there is a second concrete elevator onsite.

A pleasant surprise was the metal-clad wooden elevator that pre-dated everything else. Wooden elevators often went up in flames because of grain dust explosions, sparks from passing trains or short circuits. Finding one standing in good condition is a rare event. 

IMG_8956

Getting out of the truck with my camera, I chatted a bit with an employee and showed him my grandfather’s name on a manhole cover.

Then I looked around, finding the elevator in pretty nice shape after so many years. A previous logo on the headhouse had been covered up and replaced with simple lettering that said, “Dalhart Consumers, Hartley, Texas.”

My notes show that I also peeked into the office and met an employee named Yvette, who said they store corn, wheat, and milo.

The elevators in Canyon and Bushland, Tex., have more dramatic stories to tell. This one in Hartley merely keeps its head up and goes about its job every day.

At 252,000 bushels, Bushland stuck to the ’49 plan perfected at Dike, Iowa

by baggyparagraphs

IMG_8889By Ronald Ahrens

The 252,000-bushel Bushland, Tex., elevator that today remains in pristine condition was built by Tillotson Construction Co., of Omaha, in 1950 and followed the plan for single-leg elevators established the year before at Dike, Iowa.

Texas-Okla Logo 04Notes on the plan specify eight tanks, or silos, of 18 feet in diameter rising to 120 feet in height–certainly the tallest thing in Bushland, an unincorporated town that sits between cropland and rangeland.

Even today Bushland has just 130 people or so, and none paid attention to me as I photographed the elevator from every good angle.

IMG_8895The job 68 years ago required the careful mixing of 2,066 cubic yards of concrete from the sand pile on the site. It would be reinforced with 109.37 tons of steel. At least I think that’s the number in the company records. That line got pinched in the copying process. But 109 tons is consistent with the amount used in other elevators of similar size. The 252,000-bushel elevator built the same year in Pond Creek, Okla.–another on the Dike plan and one of two dozen Tillotson jobs in that bounteous year–used 112.91 tons of steel.

The hoppers required another 40 cubic yards in which no reinforcing steel was used.

The 21-inch-thick main slab covered 60 x 72.5 feet. A note on slab’s area saying “Act. outside on ground” records a total of 4,200 square feet. We get 4,350 square feet when we multiply those numbers. How to account for the discrepancy?

When loaded with up to 7,560 tons of grain, the elevator could achieve a gross weight of 12,880 tons. So there was never a danger of jealous farmers sneaking over at night from Wildorado, down the road to the west, and towing it away on a flatbed.

The cupola, or headhouse, was 24.5 feet wide, 50.25 feet long, and 40 feet high.

With a pit depth of 14 feet 9 inches, there was a distance of 165.25 feet between the leg’s pulley centers.

In the construction record’s Machinery Details section we find a note that says: “LIKE POND CREEK.” That means the boot pulley was 72 x 14 x 2 3/16 inches. The head pulley, as we found in our earlier visit to Canyon, Tex., was the same except for being 1.75 inches wider.

IMG_8908It turned at 42 rpm, cranking the 14-inch, six-ply belt and it’s cups that measured 12 x 6 inches at 8.5 inches o.c. The head drive had a 40-horsepower Howell motor.

Theoretical leg capacity according the cup manufacturer’s rating was 7,920 bushels per hour. But actual capacity being 80 percent of that, the leg delivered 6,340 bushels per hour, demanding only 32 hp of the motor.

The man lift had a 1.5-hp electric motor. The truck lift had a 7.5-hp Ehrsam. Some day, after our road trip series ends, we need to write a post about Jürgen Ehrsam, inventor, who sounds like a fascinating subject.

Tillotson’s Bushland, Tex., elevator glistens with paint. Is that a good thing?

by baggyparagraphs

 

IMG_8912After prowling in and out, up and down, and finding the Ag Producers Co-op elevator at Bushland, Texas, to be spotless and more than serviceable after 68 years, I struggled in the ambitious crosswind and went over the the co-op’s office just to the installation’s north. It’s just north of I-40.

Texas-Okla Logo 04As said before, I had encountered no one. Going through the back door, still, no one. But I went through to the front of the building and saw Bret Brown in his office.

Brown stood up to greet me hear my explanation. I had come to see what Tillotson Construction Co. built here in 1950. The company’s principal, Reginald Tillotson, was my grandfather.

Brown, the co-op’s CFO, wore a short-sleeve plaid shirt. He had a couple of minutes to chat with the intruder.

IMG_8920I remarked on the elevator’s excellent condition and the glistening paint job.

He said the paint was applied after the insurance company issued an imperative to seal cracks and coat the silos and main house.

In fact, he said, it was $160,000 paint job.

Yes, the result is spectacular.

For concrete, though, is paint a good thing? As reader Paul Grage wrote in a comment last week about the elevator in Rockwell City, Iowa, “The elevator is rotten in concrete terms.” Happy news to us is that it remains standing.

“But for how long who knows?” Grage writes. “Another victim of paint.”

There was a reason the builders finished the jobs with whitewash instead of paint.

Wheels will turn inside the 1950 Tillotson Elevator owned by Ag Producers Co-op, Bushland, Tex.

What’s the difference?

A quick search turns up this definition of whitewash: “A solution of lime and water or of whiting, size, and water, used for painting walls white.”

Porous whitewash allows the concrete to breath. It might also be cheaper than paint. You can mix it onsite, maybe by grinding up Hyundais built in the 1990s. I don’t know. But let’s think about it.

Next in the Tex-Okla Road Trip series: Bushland’s specs.

The 320,000-bushel Tillotson elevator in Canyon, Tex., followed the Bellwood plan

by baggyparagraphs

 

IMG_8860The year 1950 was a busy one for Tillotson Construction Co.  The Omaha outfit (my grandfather Reginald Tillotson’s company) built 25 grain elevators–an amazing number. They were in Oklahoma, Texas, Colorado, Kansas, Nebraska, and Iowa. The next year they would build one in Missouri.

Texas-Okla Logo 04The Canyon, Texas, elevator operated by Consumer’s Supply Co-Op was built on the same single-leg plan developed for Bellwood, Nebraska, in that year. It incorporated eight tanks, or silos, of 20 feet in diameter and 120 feet in height. Capacity was 320,000 bushels.

Measuring 13 x 17 feet, the driveway was underneath 10 bins. A note in the construction record mentions “5 bin Dist. Under Scale.” In all, there were 22 bins and a dust bin as well. 

IMG_8855While the Bellwood plan was used for five elevators, it’s interesting to note the slight differences in materials used. For example, Canyon took 2,463 cubic yards of reinforced concrete while Burlington, Colorado, also on the Bellwood plan, took 2,436 cubic yards (the exact same amount as the mother elevator in Bellwood and the one in Hartley, Texas, which is coming soon in this series). Rock Valley, Iowa, though, took 2,394 cubic yards.

In all, this reinforced concrete weighed 5,069 tons.

Canyon required another 20.3 cubic yards of plain concrete for hoppers. It weighed 40.3 tons.

IMG_8868

Looking up the tracks at Consumer’s Supply Co-Op’s East elevator.

There were 143.3 tons of steel used to reinforce the concrete.

This amount also includes the jack rods used to move the formwork. 

The main slab was 66 x 77.5 feet, for an area (a note says “Act. outside on ground”) of 4,806 square feet.

  • When the tanks were fully loaded, the grain weighed as much as 9,600 tons.
  • Additional structural steel and machinery weighed another 28 tons.
  • This means that the elevator’s gross weigh when loaded was14,964 tons.
  • The pit depth below the main slab was 15 feet and 9 inches.

Up above the main house, the cupola, or headhouse, measured 23 feet wide, 63.75 feet long, and 39 feet high. So the structure’s total height was 159 feet. Look closely at the headhouse photo, top of page, and tell us if it doesn’t seem to be smoking some sort of Turkish pipe.

Pulley centers of the leg were 166 feet apart. The boot pulley was 72 x 14 x 2 3/16 inches. The head pulley was shared the first two dimensions but was wider at 3 15/16 inches. It turned at 42 rpm.

The six-ply belt was 14 inches wide, and the cups were 12 inches wide and six inches deep.

IMG_8881Altogether, 34 hp was required to operate the leg; the record says two 40-hp Howell motors were installed. Theoretical capacity of the leg, based on the cup manufacturer’s rating, was 7,920 bushels per hour. But the leg operated at an actual capacity of 80 percent the theoretical capacity, or 6,350 bushels per hour.

The truck lift had a 7.5-hp Ehrsam motor, and the conveyor had a 3-hp motor.

In all, it was state-of the art in 1950, and the elevator remains in everyday use now.

 

 

The surprise in Canyon, Texas, is how the Tillotson elevator survived a blowout

by baggyparagraphs

IMG_8884By Ronald Ahrens

Too many bad things can happen at a grain elevator. For one, construction crews and elevator workers face the risk of falling. For another, grain dust can explode. And it’s even possible for a worker to be trapped in a silo.

Texas-Okla Logo 04Then there’s the problem of blowouts. We have written before on Our Grandfathers’ Grain Elevators about blowouts.

One had occurred on a Tillotson Construction Co. job, probably in 1955, at Blencoe, Iowa.

And it turned out, during our visit to the 1950 Tillotson elevator run by Consumer’s Supply Co-op in Canyon, Texas, there was the story to tell of a blowout.

Those weren’t just stretch marks on that corner silo. Well, actually, yes, they were. 

IMG_8859

As Dewayne Powell explained when he showed me around, the blowout in a single silo had occurred sometime before his tenure, which goes back eight years.

Tillotson Construction Co.’s records specify the bearing pressure of the walls at 3.1 tons per square foot. Somehow, the concrete must have deteriorated, leading to the failure.

The elevator’s importance to the Co-op is underscored by the fact that repairs were made. Powell said Gunite was used. I searched for a definition of Gunite and found this passage from the Shotcrete entry on Wikipedia:

IMG_8876

Dewayne Powell leads the way into the elevator’s basement.

“Shotcrete, then known as gunite (/ˈgənīt/), was invented in 1907 by American taxidermist Carl Akeley to repair the crumbling façade of the Field Columbian Museum in Chicago (the old Palace of Fine Arts from the World’s Columbian Exposition).[1]

“He used the method of blowing dry material out of a hose with compressed air, injecting water at the nozzle as it was released.

“In 1911, he was granted a patent for his inventions, the “cement gun”, the equipment used, and ‘gunite,’ the material that was produced.”

Whatever the term, the repair was nicely done. But Powell said he’d heard stories of chaos the blowout caused. Aside from this disaster, the 68-year-old elevator has held up quite well.

Catching the Canyon, Texas, Tillotson elevator at its doggonedest dawn glory

by baggyparagraphs

IMG_8858To make it by dawn to the Tillotson elevator in Canyon, Texas, I hit the road at 6.30 a.m. and hightailed out of Hereford, covering the 30 miles across the plain, traveling east-northeast on U.S. 60.

Texas-Okla Logo 04I was happy at last to see the elevator’s distinguished bulk on the faint horizon. And even happier there was no storage annex–just the classic 320,000-bushel job from 1950.

No one was around to chase me away. The elevator looked very well kept, like a 68-year-old with a natty haircut and fine clothes.

I prowled over the grounds to get my photos, as well as going up and down 6th and 7th streets in the neighborhood looking for a street-view. People inside their bungalows might have thought I was some kind of nut. I wondered if they ever pondered much upon their gigantic concrete neighbor.

IMG_8859By the time I finished with photos, the Consumer’s Supply Co-op store on the premises had opened up. I went inside and introduced myself, feeling proud to say, “My grandfather built your elevator.”

I elaborated about Tillotson Construction Co., of Omaha, and my mission to visit the 10 Tillotson elevators in the Texas Panhandle.

Scott Smith, general manager, and Dewayne Powell were interested to hear it. These bright-faced gents explained, among other things, that the Co-op’s charter goes back to 1926.

Two elevators are on the site. “This is our best elevator here,” Smith said of the Tillotson. The other needs repairs to the floor, among other places.

Much of this, the West Elevator, was original. Alas, the truck lift had been removed “before my time,” Smith said. 

I went out to the truck for the construction record. After my explanation of some of the specifications, Smith took it to the copier.

Powell showed me around, explained how things worked, even posed for some pictures.

The basement was clean and tidy, and Powell mentioned that at one point some of it had been used for office space. It was sure bright enough down there.

Something else that had changed: the augur below ground level had been filled in with concrete.

We went back up, and I made one more circuit around the elevator. The driveway door was open, and the Co-op’s yellow Mack truck sat in the driveway.

IMG_8883The quality of the Co-op’s operation was evident. The only things with the elevator that seemed out of order was a broken basement window, and one of the back doors had been splattered with glop.

Otherwise, things were in nice shape.

When I was ready to leave, they presented me with a cap and T-shirt with the Co-op’s emblem–a real honor. Smith recommended KJ’s Coffee and Cafe for breakfast, so I found my way across town to have an omelet.

Then, a-wondering where Palo Duro canyon–the town’s eponym–was, I set out for Bushland.

In our next post, watch for a surprise about the Tillotson elevator in Canyon.

 

 

 

Specs show capacities of the Tillotson elevator in Hereford, Texas

by baggyparagraphs

IMG_8833The single-leg elevator built at Hereford, Texas, by Tillotson Construction Company in 1951 had capacity for 300,000 bushels, according to company records. That worked out to 2,640 bushels per foot of height. The drawform walls of the silos, or tanks, rose 125 feet.

Texas-Okla Logo 04Our calculation produces a total of 330,000 bushels at this rate. There were 2,104 cubic yards of reinforced concrete, 28 cubic yards of plain concrete for hoppers, and 121.47 tons of reinforcing steel including jack rods.

The concrete would be mixed on-site, while the reinforcing steel and the lumber used for scaffolding were probably delivered by train.

IMG_8832

The elevator’s main slab covered an area of 76.5 x 56 feet and was 24 inches thick. Below it, the pit depth was 26 feet–unusually deep in comparison to that of other elevators built that year in Greenwood and David City Nebraska and (12 and 17 feet, respectively) and Malta Bend, Missouri (9 feet 3 inches).

The headhouse, or cupola, was 17 feet wide, 36.75 feet long, and 27 feet high. So the structure crested at 152 feet.

That the pulley centers of the leg were 169.5 feet apart reflected the positioning of the lower boot pulley below ground level. That one measured 72 x 14 x 4 15/16 inches. The head pulley was 72 x 14 x 2 3/16. IMG_8823

The head pulley turned at 42 rpm.

The six-ply Calumet belt was 14 inches wide. Cups were 12 x 6 inches and 8.5 inches deep. A 40-hp Howell head-drive turned the leg, and the cups bore a theoretical capacity of 79.2 bushels per hour, although actual capacity–80 percent of theoretical–was 63.4 bushels per hour.

The man-lift operated with a 1.5-hp electric motor.
