A New Type of Escapement??

Image
Here's a nice find on YouTube... from the description: Implementation and early development of a fully detached, gravity impulsed, mechanical escapement inspired by the designs of James Arnfield. Prototype built for kinematic amusement with the possibility of satisfactory timekeeping. The pendulum should at no time be connected directly to the going train and only impulsed by a falling tumbler which, after leaving contact with the pendulum, releases the escapement.  If you know more about this, I'd love to hear from you. Looks fascinating.

Troubleshoot Your Cuckoo Clock

Here is an excellent video for troubleshooting your cuckoo clock. If your clock is not running and not keeping time please check this video out. Remember that all wire bending and adjustments described in the video should be done VERY slightly. Clocks from North Coast Imports are always extensively tested and any adjustment you make should be to a very small amount.

Creative Patterns

We found this pattern maker , who had the good idea to use a vintage cuckoo clock pendulum (of the type typically used on pendulums in the '70s and '80s) to neat effect. Check out a NEW shield Black Forest Clock:

Inverted Pendulum

Image
We know what a pendulum is. It's a great device for producing regular periods, which is especially useful in mechanical clocks, when you want to break down fast power into smaller intervals (like seconds). Galileo Galilei discovered it around 1602 and Christiaan Huygens was the first to use it in a clock for accurate escapement in 1656. But what if you turned it upside down? It's easy to do by hand. Take a long rod and balance it on the palm of your hand. In order to keep it up, it requires finite adjustments by your hand. A little to the left... right... forward... Don't let it fall! Your brain accepts input from your eyes and feel of the weight on your hand to see which way the rod begins to fall, and tells your arm and hand to adjust as necessary to keep the bottom of the rod under the top... keeping it balanced. It's not that difficult to do for someone as intelligent as ourselves. Could that control be synthesized? Imagine the possibility... ...or, just l...

Changing the suspension spring on an "Americana" anniversary clock

Image
This short tutorial will give you some help changing the suspension spring on our popular "Americana" Anniversary clock . If your suspension spring is broken, replacing it is a relatively simple fix. The first step is to make sure you have the parts and tools you need. You'll need the clock, a pair of pliers, and the replacement suspension spring. The suspension spring actually looks like a little brass ribbon. notice that there are two ends with a pin, or a plastic perpendicular piece sticking out that is closer to one end than to the other. There are two square ends with pins sticking out of the sides. Carefully take the glass dome off and set it aside. Take a look at the back of the clock. Using just your fingers, pull the black plastic hand-setting knob straight off. This is only friction fit, and should not be too difficult to pull off. Please make sure you pull it straight back, and not to one side or the other. Also, pull the battery door off and remove the...

Corpus Clock

Dubbed the strangest clock in the world, it features a giant grasshopper and has 60 slits cut into its face which light up to show the time. Its creator John Taylor said he "wanted to make timekeeping interesting". BBC That's pretty much NCI's mantra - "Making timekeeping interesting." In addition to our own clocks, it's great to find extravagant works of horological art being produced throughout the world. This one is pretty fascinating. Although it has LED lights and an electric winding motor, it is otherwise all mechanical with a grasshopper escapement. By the way, our new cuckoo clock catalog should be finished printing by Friday. Make sure we have your favorite clock or jewelry or gift store on file so that they will receive our new catalog.

Clock History

The James Burke television series of the '70s, Connections still remains immensely popular. He had a real knack for telling the history of change. In this episode Burke is talking about the history of the clock, and how it relates to the development of the computer as well as mechanized production and the development of the U.S. as an industrial power. He starts here by explaining early Arabic theories in astronomy and astrology, as well as European contemporaries' need for hourly prayer in the Dark Ages. Burke takes us through history, pointing out the need for an accurate clock and the rise of Christiann Huygens's important invention: the pendulum clock . By the end of the first segment here, Burke introduces the verge and foliott - the exact escapement found in our "Rock Clock" which was in use in the Black Forest in Germany in 1640. In the second segment listed here he talkes about a fusee mechanism and goes on to show other mechanical marvels like our cuckoo...

Unpack your Black Forest Clock, or Cuckoo Clock

Image
Here are a few words on unpacking your new Black Forest clock. The pictures below are of a Rombach und Haas "Dumpling Eater," but the instructions can also be applied to unpacking almost any Black Forest clock - including Cuckoo Clocks! North Coast Imports, Inc. is proud to use recycled and/or renewable materials in packaging. Enjoy the old-world charm as you unpack your new clock. These cherished pieces are lovingly packed by the careful clock makers in the Black Forest in Germany. After carefully cutting the tape and opening the top of the box (find the top by paying attention to which way the lettering is facing on the ends of the box) lift the cardboard flap to reveal your exciting new timepiece. Using two hands, carefully lift the top of the clock out first and sliding the clock upward and out of the cardboard surrounding the bottom of the clock. The Dumpling Eater figure may have a plastic bag rubber-banded around. Carefully remove the rubber band and bag being carefu...
