Mechanical Clock Movements

!±8± Mechanical Clock Movements

ESCAPEMENT is part of the clock that controls speed and regularity by converting continuous rotational energy into discrete motions. This is accomplished through the use of gears and a lever attached to a pendulum. the most common form in use today powered by key wound springs.

When the pendulum swings the lever locks in the tooth of the gear, this is the tick. The back swing of the pendulum the lever releases the gear, this is the tock. The process is repeated over an over until the clock needs winding. Thus, the familiar tick tock of a clock. The speed and accuracy of the clock is achieved by adjusting the pendulum bob up or down. Adjusting the bob up speeds the clock, adjusting the bob down slows the clock.

The earliest escapement can be traced back to a Buddhist monk Yi Xing in china around 725A.D. He was also a Chinese astronomer, mathematician, and mechanical engineer of the Tang Dynasty (618-907). His contribution was designing and operating a water-powered armillary sphere.

Many escapements have been designed and developed over the years. One that predates the pendulum around 1275A.D. is the Verge escapement, also known as the crown-wheel-and-verge escapement. This escapement design and function is similar to a teeter- totter on a playground. The problem was this system had no natural frequency of oscillation, it is simply force pushing inertia around.

The next development was attaching the verge escapement to a pendulum. Galileo had the idea for a pendulum clock in 1637. This increased the accuracy of clocks enormously, from about 15 minutes per day to 15 seconds per day, leading to their rapid spread as existing clocks were retrofitted with pendulums. In order for this to work the axis of the verge became horizontal. This design was good at keeping time, but the swing of the pendulum was very wide up to 100 degrees.

Anchor escapement also known as recoil escapement was the next big development in 1670. The swing of the pendulum was greatly reduced to 4-6 degrees. The teeth of an anchor escape wheel project radially from the edge of the wheel, much like an up side down anchor. The second pendulum clock was built by Christian Huygens, in 1673. Development of this escapement allowed the introduction of the long clock better know as a grandfather clock, made by William Clement around 1680. The increased accuracy resulting from these developments caused the minute hand, previously rare, to be added to clock faces beginning around 1690.

Improvements in designs lead to the Dead beat escapement introduced around 1715 by George Graham. This design lead to the lever escapement. The up side down anchor was given a rounded edge so as not to lock the gear. This allowed the pendulum to operate the clock on both back and forth swings. Wear on the escapement was greatly reduced. In most wall clocks that use a pendulum, the pendulum swings once per second. In small cuckoo clocks the pendulum might swing twice a second. In large grandfather clocks, the pendulum swings once every two seconds,

The lever escapement is widely used and very accurate. Clocks today have a very long and rich history. Depending on which clock suits your need or desire you can have confidence in there accuracy and dependability.

Kymaro Body Shaper Review

!±8± Kymaro Body Shaper Review

Today's body shapers for women are greatly improved from the old fashioned girdles of the past that your mother or grandmother may have worn. You will find modern shapers offer not only performance but also comfort and style. Body shapers are designed to be undetectable under clothing; people are supposed to think that a woman is as slim and shapely as the shapers make her look. Customers have said that the Kymaro Body Shaper has improved their posture as well as given them a slimmer shape. Those who have had negative comments about the shaper could have ordered the wrong size. I would suggest adding 10lbs to your weight and going by that since they can run a little small at first. The company also suggests soaking the garment in cold water before wearing it to improve flexibility.

Wether you are a size 6 or size 20, a flat tummy is hard to achieve. The Kymaro body shaper will also give you a slimmer silhouette. It is even comfortable enough to wear all day at work. The material lets you breathe and it is not confining.

BOB Revolution Stroller 2009 - Selecting the Right Model

!±8± BOB Revolution Stroller 2009 - Selecting the Right Model

Parents who own a BOB Revolution stroller rave about it for many reasons. Due to this "raving", many people have heard about the Revolution stroller and would like to purchase one, but might not be aware of the different choices to make before selecting the right model for their needs.

Here is a list of common questions and answers someone might have when setting out to purchase a BOB Revolution:

Should I buy a Single or Double ("Duallie")? This is actually an interesting question, and at first glance it might seem to have a simple and obvious answer. The bottom line is - Will it be used for one or two children? The Revolution is a bit of an investment to make (well worth it by parents' testimonials) whether purchasing a single or Duallie model.  Any conditions in which two small children are cared for the Duallie comes in mighty handy!  (Note: The Duallie holds up to 100 lbs. - 50 lbs per seat, the Single up to 70 lbs.)

Can I use the Revolution for normal daily use - or just jogging? One of the things I love the most about the BOB Revolution stroller is how versatile it is. It features a revolving wheel that makes it an ideal stroller for everyday use (going to the mall, the zoo, etc.) - but the wheel locks into place to make the stroller a "jogger" - in fact it's one of the finest jogger strollers available.

Can I use the Revolution for both on-road and off-road jogging? FYI - There are basically two types of wheels available for the Revolution - polymer and aluminum. The polymer wheels have a deeper tread to them, giving them great traction for off-road use. On the other hand, the aluminum wheels have a slicker tire and are an excellent choice for on-road jogging.

Which color should I purchase? There is a nice variety of colors for the BOB 2009 Revolution including Black, Mesa Orange, Navy, Chocolate/Blue and Chocolate/Pink.

No matter while model you choose from the BOB Revolution Stroller 2009 lineup, you will love it's easy use as well as the extra comfortable ride and safety features for your baby.

The Schwinn Jogging Stroller - How Celebrity Moms Stay in Shape!

!±8± The Schwinn Jogging Stroller - How Celebrity Moms Stay in Shape!

This is a very modern and very real challenge that you as parents face every day. And this challenge is to stay in shape. With everything you do, it's not your fault that you do not seem to find time to exercise.

Millions of parents across the United States face the same dilemma.

A large percentage of them must find a way to lose weight and keep it off. Their strategies tend to include more andStay on to find a healthier diet and ways to incorporate exercise into their daily operations.

Now I know you probably hate the word "D". The mere mention of the word diet brings images of the bars of health disgusting and tasteless food. But there is no need to radically change the way you eat. Just change what you are recording, so as not to consume 5000 calories a day to go a long way!

Then you have to be integrated into the day with exercisesomeway, right? You cannot add minutes into the day and you sure as hell do not want to get up earlier just to exercise. 
 
So how is it done?
 
Well, certain tools, like jogging strollers, are a great way to incorporate exercise into your day and keep your baby entertained at the same time. Your baby gets entertaining scenery and fresh air and you get all that plus the ability to easily burn calories.
 
So since you really do know how to eat better (even though it is easier said than done), let's talk about jogging strollers. In particular, you want to know about the Schwinn jogging stroller, because they really set the bar and their right where affordability meets good quality.
 
First, a Schwinn jogging stroller is considered to be an alternative to "big-name" brands like Bob and Mountain Buggy. Schwinn is an American-made stroller line owned by Pacific Cycle.
 
 Schwinn has a long and famous history as a bicycle maker and the company is known for the high quality of their products (that seldom come at a cheap price).   Schwinn also produces the famous Instep strollers that bear a resemblance to Schwinn strollers, but are a step-down in quality, features, and price.
 
Schwinn produces at least ten models of fixed and swivel strollers. Models are generally in the 0 - $ 275 range and double jogging strollers (for two babies) can reach 0.
 
Most are designed for everyday use, but the Schwinn Joyrider is designed for serious running.
 
While the seats recline, they do not move into a completely upright position. This is the number one complaint for the Schwinn jogging strollers. Some consumers report buying extra padding or simply using a folded blanket to prop their toddler more upright.
 
The most popular Schwinn stroller models are the Schwinn Safari TT (swivel wheel), Schwinn Free Wheeler (swivel wheel) and the Schwinn Free Runner (fixed wheel). The importance of a swivel wheel and extra-wide tires is that it enables the stroller to "turn on a dime" and conquer some pretty tough terrain.
 
The Schwinn Free Wheeler is simply an upgraded version of the Safari TT that comes with an aluminum frame (instead of steel) and shock absorbers for a smoother ride.
 
Moms tend to like the strollers because they are easier to push than conventional strollers. Many-a-Moms know what it is like to always have to get Dad to push the stroller. Frankly, you can have a really shitty experience trying to push one of those plastic-wheeled strollers.
 
These jogging strollers also come with trays and storage for parents and the child (or children) so that all of your accessories can go on the stroller instead of your pocket or a bag on the side of the stroller. The bodies of these strollers are typically made of aluminum, making them lightweight and easier to push.
 
Schwinn jogging strollers also feature removable seat padding (for easy cleaning) and adjustable handle bars (because parents aren't the same height, right?).
 

Buyer's Report:

"I purchased this jogger a few months ago and now that the weather is warm I am really getting a lot of use out of it and have some feedback to share.

The pros of this stroller are:

1. Large sunshade that can be adjusted very well to block the sun.

2. It seems to be very comfortable for my daughter, we started using it when she was 3 months old and she seemed very cozy and secure in it. My five year old, who is 38 lbs and 46 inches can also ride in it fairly comfortably when she is tired.

3. The seat adjusts from almost fully reclined to sitting.

4. You can actually store a decent amount of stuff in the basket.

5. The swivel wheel and large air filled tires make it a dream to push around and minimize bumps.

6. Very easy to engage and disengage the foot brake.

7. It has very nice parent and child trays that are removable.

Cons:

1. My less expensive, double jogger had a handbrake on the handle that could be used to slow the stroller on steep hills, this stroller does not have a brake. It only has a foot brake to use when you are completely stopped so the stroller doesn't roll away.

2. There is no mesh in the stroller to increase airflow and might get very hot in warm weather.

3. It folds easily, but there is no latch to keep it folded and it opens as you are trying to take it out of the car.

4. Even when folded, it will not fit in the cargo area of my Caravan unless I remove the wheels - it is rather bulky.

Overall, I am very happy with this purchase and I am sure we will get a lot of use out of it. Luckily the trails we hike are mostly within walking distance from our home and we don't have to try to transport this stroller often." By R. Cammero in PA (Amazon)
