As tower anchors have been somewhat overlooked causing in some instances much loss, these notes are written to call attention to the importance of properly designing them so that the maximum strength of tower may be obtained with the most economical outlay. The notes show: 1. A method of figuring the loads to be resisted by the anchors. 2. The importance of resisting the horizontal as well as the vertical loads. 3. The effect of the shape of the anchor on strength of tower. 4. Various types commonly used. 5. The economy of the use of an all-steel anchor.
