  • Jim Wheeler's Remarkable Wooden Clapper
    Jim Wheeler’s remarkable wooden clapper. On Christmas Day 2004, just after 10 o’clock while we were ringing for the Cathedral’s main service, we heard the dreaded crash and the tenor was silent. It is a sound familiar to lots of towers with heavy bells. The tenor clapper had broken just three years previously and soon after that a gudgeon on the eleventh had to be replaced. The bells being out of action was inconvenient as the Cathedral’s bells are now rung more as part of Cathedral and civic life. Eyre and Smith moved quickly and the tenor clapper was replaced under their guarantee and arrived in February. However, we were able to ring the tenor again the next day. Losing the tenor’s clapper would normally have meant that we could not ring the 12 bells open on New Year’s Day. However, a few months earlier Jim Wheeler had welded an old, broken, cast iron (SG) tenor clapper as a precaution. We don’t like the bells to be out of action. This was the beginning of his experiments with clappers and Jim’s eventual solution: a tenor clapper with a wooden shaft. We put the welded clapper in the tenor thinking we might get a few rounds and then hear the dreaded crash again. What happened was remarkable. First the clapper didn’t break. It lasted until Eyre and Smiths’ remodelled and significantly better replacement arrived in February, and it was rung for over 6000 changes, including a quarter peal. Not only did the clapper work, the bell sounded different.

    Manx Bells by R. W. M. Clouston File 01: The Entire Book This document is provided for you by The Whiting Society of Ringers visit www.whitingsociety.org.uk for the full range of publications and articles about bells and change ringing MANX BELLS Ranald W M. Clouston BSc Eng FSA PUBLISHED PRIVATELY 7986 2 Feltham and Wright in their tour of the Isle of Man in the summer of 1797 made sketrhes of the churches they visited; these all show open bellcotes and quite small bells. At that time Kirk Patrick was ruinous and had no bell; St. Patrick's Church in Peel Castle, Kirk Braddan, Kirk Marown and Kirk Halew each had double bellcotes with two small bells. The remainder had only small single bells. Some of these have survived, but none were cast earlier than the 18th Century. The larger bell at Kirk Braddan Old Church, 23'1,, inches diameter, bears the date 1780 incised on the shoulder. This fabric was re-erected in 1773 on the site of a much older church. The bell bears a normal arrangement of moulding wires, six canons and an argent. While incised dates and inscript­ ions can be put on a bell at any time after casting, the details of the bell do support 1780 as the likely casting date. Probably from an English foundry, as the design shows that the founder was quite used to casting bells and moulding the quite intricate canons and argent, the loops on the crown. The companion bell, 17~ inches diameter, is a little later, say 1800; there are no moulding wires on the shoulder or by the inscription band, and though there are argent and six rectangular section canons, the moulder has made a mistake in putting the cast-in crown staple, which supports the clap­ per, 90° out compared with the canons.

Included is a brief history of the development and growth of the fou.ndry industry. Operation sheets for the manipulative processes in a foundry unit are also included. Findings and Conclusions: The success of any industrial arts program is determined largely by how well the program is planned and administered. The purpose of this type of unit in shop is to give a student as many experiences as possible and to offer an outlet in his quest for explo­ ration.

  • Birmingham Metallurgical Society Lectures and Papers
    Birmingham Metallurgical Society Lectures and Papers Copper strip at IMI Volume I Metals and Alloys Editor: I.L. Dillamore Birmingham Metallurgical Society An Anthology of Papers reflecting the evolution of the subject of Metallurgy and the rise and fall of the associated industries in Birmingham. Represented by papers presented to the Society by National and International Experts and by major contributions made by Members of the Society. Volume I The Metals and Alloys Introduction The Birmingham Metallurgical Society was already seventeen years old when it was registered at Companies House. In those years the understanding of the behaviour of metals had advanced significantly, but still had a long way to go. The aim of the collection assembled in this and two following volumes is to show through the activities of the Society and its members how the subject of metallurgy evolved and how those companies that created the Midlands metal industry wax and waned. The Society was much involved in 1908 in the creation of a national organisation, The Institute of Metals, to serve the interests of the non-ferrous industries. The Institute's first office was in the University. In 1945 it was on an initiative of its members that a body was formed to give professional recognition to qualified metallurgists: the Institution of Metallurgists, which represented all metallurgists, both ferrous and non-ferrous. Many of the lectures in the first 50 years are shown as being before the 'Coordinated Societies'. These were the Birmingham Metallurgical Society, The South Staffordshire iron and Steel Institute and the local section of the Institute of Metals.

  • The Architecture and Industries of Canongate DISTRIBUTION of INDUSTRY TYPES
    PINTS, POLITICS AND PIETY: the architecture and industries of Canongate DISTRIBUTION OF INDUSTRY TYPES Appendix A Alex Adamson, Lynn Kilpatrick and Miriam McDonald March 2016 Historic Environment Scotland (HES) John Sinclair House 16 Bernard Terrace EDINBURGH EH8 9NX Tel: 0131 662 1456 Web: www.historicenvironment.scot www.canmore.org.uk 1 This document forms part of a larger report: Pints, Politics and Piety: the architecture and industries of Canongate. Introduction to Maps Showing Distribution of Industry Types As part of the analysis of industrial activity within the Canongate study area, we took six timeslices across the area’s history based on contemporary mapping and corresponding Post Office and other Directories. From the Directories, we noted the number of instances of various industry types within the Canongate boundary, grouping these under generic types of industrial activity. The result of this analysis follows in this appendix, with extracts of the historic maps, the distribution maps and a short narrative explaining the finding for each timeslice. The timeslices and maps chosen were: A.1: Williamson’s Directory 1773-4 and William Edgar’s ‘Plan of the City and Castle of Edinburgh’, 1765 A.2: Post Office Directory 1799-1800 and John Ainslie’s ‘Old and New Town of Edinburgh and its Environs’, 1804 A.3: Post Office Directory 1819-20 and James Kirkwood & Sons’ ‘New Plan of the City of Edinburgh’, 1821 A.4: Post Office Directory 1853-4 and Ordnance Survey 1st Edition 1:1056 map, 1852 A.5: Post Office Directory 1876-7 and Ordnance

BY EDW^ARD KIRK, PRACTICAL MOULDER AND MELTER ; CONSULTING EXPERT IN MELTING. AUTHOR OF "the CUPOLA FURNACE," AND OF NUMEROUS PAPERS ON CUPOLA PRACTICE. ILLUSTRATED PHILADELPHIA : HENRY CAREY BAIRD & CO., INDUSTRIAL PUBLISHERS, BOOKSELLERS AND IMPORTERS, 810 Walnut Street. 1911 J Copyright, 191 i BY EDWARD KIRK I/-/50Z3 C f:CI.A2Sl>SJ2 PREFACE. This volume has been prepared at the earnest request of many founders seeking practical information on FOUNDRY Irons and their manipulation in the production of the various lines of castings. It has been the aim of the author to present, in a condensed form, only such matter as is of practical value to the founder and to eliminate as far as possible all theories that have not been established as principles and all laboratory experimental work that has not been fully demonstrated to be useful in actual foundry practice. It has been endeavored to give all useful up-to-date data on the manipulation of Foundry Irons as actually practiced in foundries, by both the old and the new methods; and thus, it is hoped to place before the founder, foundry foreman, moulder and melter such a variety of methods that he cannot fail to ob- tain desired results under any and all of the various conditions met with in the manipulation of these irons.
