Westclox Big Ben Chime Alarm Movement Photos

December 15, 2007 . by Bill

My son’s chime alarm needed some adjustments, and while the clock was opened up, I thought I’d try some quick close up photos with my digital camera. The camera was mounted on a tripod, manual focusing mode was used, no flash, illuminated by the ceiling and bench fluorescent lights. The self timer was used, to avoid any camera shake caused by pushing the button.

The movement is dated 11 50 (November 1950). It is beautifully nickel plated, as were many Westclox movements. This is the full image, resized from 3072 by 2304 pixels to 500 by 375 pixels for web display. It was sharpened with the Photoshop unsharp mask filter and displayed here at 40% JPEG quality:

Same as above with unsharp mask filter:Chime Alarm Movement

500 by 400 pixel portion of the image showing balance and spring, pallet fork and escape wheel:Chime Alarm Movement
Note: for better pictures a setup with floodlights and reflectors can be used. These photos show how good the photos can be using a very quick setup.

    I have an Westclox Big Ben that I’m repairing (I’m a novice/hobbiest repairer) and having trouble finding the correct mainsprings. I’ve found the 5/16″ x 48″ spring in Timesavers but can’t find a replacement for the other 1/2″ x 48″ spring. Any suggestions?
