Gumball, Rallied

Bought from a yard sale in Morgantown, Indiana, this XYZ Vending Bulk-PRO triple-head gumball machine is not as old as originally imagined. XYZ Vending was founded in Atlanta, Georgia, in 2003, and closed in 2009. But for $8 one can't go far wrong.

The cabinet was separated into three parts and the kinks hammered out. It was rubbed down with steel wool, sprayed with two coats of epoxy primer, and then with a number of coats of red lacquer. New cam locks were fitted to the lid, through which the machine is filled, and to the rear door, through which the quarters are collected.

The triple volume-control and delivery wheel mechanism was stripped down, scrubbed, disinfected, and put through the dishwasher. The metal springs and screws were cleaned-up with a brass wire brush as the mechanism was reassembled.

Each of the three coin mechanisms was cleaned and greased. The brightwork was brought back to life with the aid of fine steel wool. Scratches to the polycarbonate windows were reduced with judicious use of car polish, the 25¢ labels to the rear of the windows carefully preserved. Just gumballs to add.

Venner Time's Right

Venner is synonymous with time switches: Robert Francis Sidebottom Venner was the electrical engineer who invented them. His business was founded in 1906. It was incorporated in 1911 as Venner Time Switches Ltd, a private company; went public in 1937; and was acquired in 1970 by AMF (American Machine and Foundry Co.) International. Venner's electromechanical time switches provided clockwork back-up to electrically-driven mechanisms, most typically in street lighting. The company was also responsible for the initial installation at pedestrian crossings of very many of the UK's Belisha beacons.

This Venner Type 99567 is from the 1930s, and is wholly clockwork. A knurled nut in the centre of the clock face can be loosened and the 'In' (on) and 'Out' (off) time settings adjusted. The clockwork rotates the mechanism and the pegs attached to the time markers throw a cam. A circuit is formed by the cam dropping copper prongs into Bakelite pots of conductive mercury. The work on this example has been limited to stripping and painting the case, and winding the clock.

Warsaw Uprising Memorial

The Warsaw Uprising was an attempt by the Polish resistance, commencing 1 August 1944 after nearly five years of German occupation, to liberate the Polish capital. It was timed to coincide with the approach to the city of the Soviet Army. The Uprising was supported by the Royal, South African, Polish and (for just one day) US Army air forces, and by the Polish First Army.

The resistance forces had control of much of the city centre by 4 August. Circa 1,200 Polish Army soldiers managed to cross the River Vistula, but the Soviet Army deliberately stopped short of the city and sat out events, as the USSR wanted to weaken Polish resistance to its intention to annex the country for itself. The Soviets had an air base just five minutes flying time from Warsaw, but their air force failed to back the Poles. They even refused to allow Allied air forces to land.

The Uprising was utterly crushed. About 8,000 of the German and about 16,000 of the Polish combatants were killed. Between 150,000 and 200,000 civilians were executed by the Germans. A further 700,000 civilians were expelled from the city. When the Poles surrendered on 2 October 1944 the Germans systematically levelled more than a third of Warsaw, which was 85% destroyed by the end of the war. The Soviets waited until the Germans had left before entering the city.

Communist control of Poland post-WWII meant that the Uprising went without a memorial for over four decades. On 1 August 1989, the 45th anniversary of the Uprising, the hundreds of thousands of people immolated by totalitarianism were finally granted an official memorial. Designed by the sculptor Wincenty Kućma and the architect Jacek Budyn, the memorial is in two parts: a resistance group running from a collapsing building, and another entering the sewers via a manhole cover. May all rest in peace.

Enniskillen - Eulerian Bridges

Located between the Upper and Lower parts of Lough Erne, Enniskillen is an island town, the only one in Ireland. There are eight bridges. Each vertex of the network of these has an even degree. It is thus possible to make an Eulerian walk, crossing each bridge once only, to return to one's start point. Built in 1885, West Bridge is the oldest.

Working clockwise, to the north-east of the island is Johnston Bridge, completed in 1954. This is in two sections (above and below), linked by Cherry Island. The bridge was strengthened in 2015-16.

Queen Elizabeth Bridge, also of 1954, relieves the adjoining East Bridge.

East Bridge dates from 1892. Its eastern end intersects with that of Queen Elizabeth Bridge.

South of this is the modern Wellington Road Bridge, which carries the A4 bypass.

The two bridges to the south of the island are modern footbridges. The first of these crosses to the Erneside shopping centre. It was installed in 1989.

The second, Millennium Bridge, joins the island to the Derrychara area.

Finally, Castle Bridge was completed in 1983 to provide relief to the nearby West Bridge. It carries the other end of the A4 bypass.

Enniskillen - Desmonds

Desmond and Sons was a Drumahoe-headquartered clothing company. Founded in 1885, it was Northern Ireland's largest private sector manufacturing employer, with over 3,000 staff across ten textile factories.

Dangerously, since the 1960s Desmonds' sole customer was the retailer Marks and Spencer. In its final five years the company moved all its manufacturing operations to joint venture facilities in Bangladesh, Sri Lanka, and Turkey.

The Enniskillen factory closed in 2000. In 2004 M&S switched to direct supply from the overseas suppliers, and Desmonds went into liquidation. The 4.6 acre site is due to be levelled and redeveloped for housing.

Llyn Brianne - Dam Impressive

The Llyn Brianne dam was built as part of the River Towy Scheme, about six miles downstream from the river's source. The reservoir holds over 13,400 million gallons when full, and supplies drinking water to much of south-east Wales.

The dam has a core formed of nearly 14 million cubic feet of clay, protected by rockfill to both faces, nearly 60 million cubic feet extracted from immediately local sources. It is the largest clay core dam in the world.

The dam crest is about 950 feet long, and about 300 feet high, the tallest in the United Kingdom. It is accessed by an unusual bridge (above) that crosses a monumental spillway, the largest in Europe, and a favourite with extreme kayakers. A second bridge (below) crosses the lower end of the spillway.

The reservoir has a maximum depth of approximately 275 feet, and a surface area of circa 530 acres. It is fed from a catchment area of roughly 22,000 acres. Just one unoccupied farm was inundated when the reservoir was filled.

The principal contractor was Wimpey Construction, and the dam was formally opened on 15 May 1973. The spillway was raised by about three feet in 1996 as part of construction of a hydroelectric facility at the foot of the dam. 4.6 megawatts of electricity are produced from the three turbines.

Sofia - Monument to the Soviet Army

Built in 1954, on the tenth anniversary of the 'liberation' of Bulgaria by the Soviet Army, the monument to that army features a central pedestal, 121 feet high, topped by a statue featuring a soldier and a Bulgarian family. 

This is surrounded by a large enclosed area, now somewhat ruinous, on the leading edge of which are two secondary but still monumental sculptures. The figures are secretly painted from time-to-time to indicate solidarity with various peoples and countries subjected to present-day Russian totalitarianism.
