This is a vintage technical engraving titled "Belpaire Boiler For Cape Town Electric Supply Works. Constructed by Messrs. Clayton and Shuttleworth, Engineers, Lincoln" It is in excellent condition and was published in a British engineering journal. The page is dated April 8,, 1898. The engravings show a detailed side view of this locomotive type Belpaire boiler. The engraving is accompanied by an article describing the boiler and its engineering specifications. Classification of Boilers as to Fire-Box Used. Boilers are frequantly referred to also and designated by the type of fire-box contained, such as Belpaire, Wooten, and Vanderbilt. This designation does not in any way conflict with the classification of different types of boilers already given but refers to the general character of the fire-box; that is, the boiler may be classified as a straight top boiler and at the same time a Wooten fire-box. Since this is true it is necessary to know the distinction between the Belpaire, the Wooten, and the Vanderbilt types of fire-box. The Belpaire boiler has a fire-box with a flat crown sheet A jointed to the side sheets B by a curve of short radius. The outside sheet C and the upper part of the outside sheets D are flat and parallel to those of the fire-box. These flat parallel plates are stayed by vertical and transverse stays and obviate the necessity of crown bars to support and strengthen the crown sheet. The advantage gained is that the stay bolts holding the crown and side sheets can be placed at right angles to the sheets into which they are screwed. From: http://www.sdrm.org/faqs/boilers/page38.html The overall size is approx. 11 by 15 inches. There is text on the reverse side. This is an original period item, over 100 years old and guaranteed to be as described. When matted and framed these antique prints make very fine gifts! We can mail these directly to a third party if you wish. (Belpaire boiler cape town electrical supply works 1898 was posted and is owned by: Lucia Hernandez) |
