BITS ON BOILERS

Sawmill

A steam powered sawmill that was developed from an old Glass Plate negative by a friend of mine. We know nothing about it, but it is so clean and interesting in detail -1 thought I'd send it to you. Courtesy of Geo. S. Clark, 254 Pond Point Avenue, Milfor

I would like to ramble a bit about Boilers, and a few connections, if you will allow me. I have received quite a few letters asking my advice on various repairs and problems, that different steam men have had on their boilers. I am always glad to pass on any knowledge that I have.

I have been fairly busy with boilers myself, as it has been very cold up here until just recently, when the weather broke up and warmed a bit.

I received a phone call from a drilling company, asking my advice about bringing boilers into Alberta from Saskatchewan. I advised them to have someone competent to go down and look them over and make sure they were in very good shape as our inspectors are very rigid about condition. However, the drilling company decided to take a chance and they trucked the boilers up to my shop to have them put in good condition.

There was a 1912 J. I. Case 32 hp boiler, a 1911 Case 25 hp boiler, and a 1915 28 hp Case boiler. After they were unloaded I took a quick look at them and here is what I found. The 32 hp boiler had the smoke box rusted out at the bottom, plus all the rivets were corroded off by the hand hole, in the flue sheet, the skirt under the firebox was half rusted off. The firebox needed 23 stay bolts replaced and also two stay bolts were missing and in their place were pipe plugs screwed into the crown sheet and outer wrapper sheet. Needless to say, the flues were shot and most of the other stay bolts had been leaking. So it has the 'X' on it that means condemned. What a pity!

Next I checked the 28 hp boiler and on both left and right sides of the water legs was a beautiful bulge about 12 inches long and 6 inches wide, at the O.G. ring. By this I mean the curve at the bottom of the water leg where it bends over to be riveted on the outer shell. This had a nice bulge below the flues and also a bulge below the door and above it. I cut the side section out of the water leg and it was just like it had been poured full of cement and every bit as hard. When I cut the section from the O.G. ring it was only about 1/8 thick in that area. Another 'X' stamped on this boiler. What a pity!
