Print on Demand. This book details the crucial equipment and techniques for safely operating and maintaining army observation balloons during wartime. With the rise of aerial warfare, observation balloons played a vital role in reconnaissance and surveillance, providing invaluable information to ground forces. The author describes the intricate tension meters used to safeguard the balloons from excessive strain and the portable maneuvering blocks and spiders employed for controlled ascension and descent. Detailed instructions and diagrams guide readers through the proper handling and maintenance of these essential tools. The book also emphasizes the significance of danger cones and clamps to prevent aircraft collisions. Additionally, it presents a simple yet effective device for testing the integrity of gas valves. By exploring these essential aspects of balloon operation, this book serves as an invaluable resource for understanding the intricacies of this historic military technology. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. …

In order to safeguard the observation balloon from damage due to high winds and also to protect the cable from excessive strains it is necessary to frequently measure the tension to which the cable is subjected.
There are two ways of obtaining this tension. First, the tension indicating device is built directly into the winch and is so arranged that the load on the cable is constantly indicated. If it is desirable, a registering device can be used, and thereby a graphic record of the tension throughout the flight is obtained for future use. However, this latter feature has not been deemed necessary in the United States Army Air Service.
Second, a portable tension meter is also in use. This weighs between 6 and 7 pounds; is temporarily applied to the cable close to the winch; a reading is taken and noted. The general principles of the tension meters are shown in figure 1. The cable is made to pass under three rollers, R, R' and R. The roller R 1s placed midway between the two rollers R' and R, so as to deflect the cable. This places a resultant pressure (w) against the roller R in the direction shown by the arrow. In the spring-type tension meter this pressure on roller R is resisted by means of a coil spring (see Plate I, fig. The greater the tension on the coil the more this spring must be com pressed ln order to balance the thrust (w) on the roller. _the com pression of the Spring is indicated by graduations on the container by means of which the tensions in kilograms are indicated.
