    TELEPHONE SWITCHBOARD
    January 17, 1882 - Chicago, Illinois, U.S.A.

    A telephone switchboard was issued a U.S. patent to Leroy Firman of Chicago, Illinois (No. 252,576), which was assigned to the Western Electric Manufacturing Co. Also of Chicago. With his invention of a “multiple switchboard for telephone exchanges,” Firman addressed the problem of increasing numbers of subscribers. Previously, single switchboards, each with an attendant, served their group of individual lines. A large exchange was thus divided up into a number of internal exchange switchboards which were worked together as necessary, with trunk lines between the boards. Firman devised an arrangement to handle an exchange of a thousand or more subscribers with line status information exchanged between switchmen.

    PUNCHBOARDS
    January 17, 1905 - Chicago, Illinois, U.S.A.

    The first U.S. patent was issued for a punchboard to Charles A. Brewer and Clinton G. Scannell of Chicago, Illinois, described as “vending devices.” They were manufactured by Charles A. Brewer & Sons in the same city. (No. 780,086). Even though the equivalent of punchboards had been around for many years, they had never been available in such a neat and portable form. The invention of board stuffing machines and ticket folding and plaiting machines in the late 1910s was probably the key factor which allowed the punchboard industry to flourish. Once the boards became cheap to manufacture, they flooded the country. Noted gambling author John Scarne estimates that 30 million punchboards were sold in 1910-15.

An Introduction To Karate Training:

Most likely one of the most well known forms of martial arts around the world is Karate. This is most likely because it features all the elements that you will want in a martial art. Karate can certainly help you to be physically and mentally fit, it may be a competitive sport and it can provide skills for self defense.

The word Karate means "empty hand" in Japanese and this system of strikes, kicks and punches is something that just about any adult or youngster can be taught. This is certainly one of the few martial arts where the whole family can participate. If you are new to this and you're wanting to know what you might expect from a Karate class we're going to take a look at some of the basics in this article.

You'll find that there are several types of Karate with different focus on either strength or speed. A lot of Karate lessons begin with warm ups that include stretches and exercises. All these warm ups help build our flexibility so that we can do our kicks and moves without harming ourselves. It is very important to be well conditioned and well developed so these warm ups are essential. Without a doubt, you'll feel much better and stronger after only a few Karate lessons.

After your warm up, you will begin to perform specific Karate moves. Your stance and feet placement is essential in Karate and to make certain that every movement is correct, you'll be doing a particular move many times over until it's done correctly. You'll usually be shown the move first by your teacher and then you get the chance to do this yourself. The continual repetition can certainly help make the moves you learn become part of your instinct so that when you do a certain strike, it all comes to you easily.

One other aspect of Karate is what is called "kata" which is basically doing a sequence of different moves in a combination of strikes, kicks and blocks. It is common to see "kata" being executed at a Karate convention and it is taught to students as they move up the grading system. At some point during your lesson there will also be a chance for some live training with individuals of a similar experience to you. This is to help you obtain some real experience with an individual and help you ascertain where you stand in your learnings. While sparring sounds dangerous, it is really a light exercise to help you check if you are correctly positioned and angled when you do different moves and strikes.

As you get to the end of lesson, you're going to be winding down by doing various stretches. It is actually fair to say that every club will have their own way of doing things but in most cases this gives you an idea of what to expect if you join a Karate club.
