The 1960’s. It sure was an interesting era for Americans. The era was dominated by Civil Rights protests, the Vietnam War, social unrest, the assassination of President Kennedy, peace, love and rock & roll.In the construction industry, from about the time of the depression up until this point, hard roofing and the recognized need for snow guards had been on the decline. There were undoubtedly snow READ THE REST….
For those of you who’ve been following this blog series, you’ll notice that there was very little going on in terms of snow guard technology and development during the 1940’s and 1950’s. Why is that? Early on in the 1950’s, the US economy really started to take off. Construction boomed (and, as evidenced by the Baby Boom, so did the population). WWII was in our rearview READ THE REST….
My searching hasn’t turned up much for the 1940’s era. The one patent I found through a reference from a more recent patent is #2243256. This patent applies to a formed metal shingle. Built into the face of the shingle are several raised bumps. These bumps were likely inserted to stiffen the product and minimize damage during transportation and handling. I’m actually a little surprised that READ THE REST….
For those of us who were involved in the construction industry between 2008-2012, we had a taste of what the 1930’s may have been like. This was the era we sometimes still refer to as the “Tool Belt Recession”. Many projects that were pending when the bottom dropped out were never started. Projects that were underway cut as many details as they could from their budgets. READ THE REST….
Ah, the Roaring Twenties. It must’ve been a fun time to be alive! The economy was booming, the country was growing, we weren’t involved in any military conflicts and it seemed that everyone was making money. In general, it was a really good time in US History. I’m told that there’s even still a speakeasy bar from the era somewhere in Milwaukee, Wisconsin, called The Safe READ THE REST….
I’ve spent a good deal of time combing over old notes, documents, and patents, and I thought it appropriate to point out a concern about the credit given to Emri W. Clark in my previous blog. First, as with all patent claims and awards, the public assumes that the owner of the patent is truly the inventor. I mean, after all, the government has given the READ THE REST….
I’ve got to hand it to Emri W. Clark of Nashua, New Hampshire. His snow guard invention, patent # 625,144, awarded in 1899, is probably the single most knocked-off pad-style snow guard design that I’ve seen – and for a few very good reasons. First, I can’t help but to speculate that Emri himself must’ve been a slate roofer. He seemed to understand that the material READ THE REST….
In my last blog, we looked into the evolution of snow guards through the history of roofing. This time, we’re taking a giant leap backwards, into the 90’s….The 1890’s! Below is a patent for snow guards that were made in the late 1800’s, a pipe-style system made and sold as Dugan’s Patent Snow-Guards. The date on the original patent is August 7, 1877 and the letterhead READ THE REST….
From the industrial revolution of the 1890’s until roughly the mid 1940’s, slate, tile and metal roofing was commonplace among roofing installers and builders. The craftsmen of the era understood the materials, how to work with them, handle them, maintain and repair them and they understood that snow and ice would slide off suddenly (and sometimes frighteningly). During the roughly 50 years of the hard-roofing heyday, READ THE REST….
Last week, we covered Snow Guards for Solar Panels, and since that post, several questions and comments have come up in regards to the pros and cons of the practice of managing snow and ice on solar panel arrays. I should start by saying that I’ve always been a strong advocate for not using snow retention devices unless they’re needed. If there isn’t a problem, there’s READ THE REST….
