In the actual execution of the work of devel oping an attractive and efficient turn, it is always essential to supplement the ground design of the turn with groups of plantings. These plantings will frame certain portions of the turn, thereby softening some of the uninteresting and particularly awkward lines as shown in photographs Nos. 13 and 13. On the other hand, these plantings often emphasize the interesting outlines of some of the curves, as shown in photograph No. 10. The relative value of plantings in these designs is seldom appreciated by the person who has not given considerable thought and study to
the effectiveness of these areas when properly framed with plantings.
In each of the illustrations the important measurements are indicated in figures. Other minor measurements may be scaled upon the diagram. Oftentimes if space is available these turns may be increased by from one to two feet in the major dimensions. The turns shown are the minimum space required for operating the automobile.
This article is compiled with reference to the space required by the latest models of large and small cars. This important question should be considered from all of its angles, with reference to both large and small machines, and there is no garage or entrance turn so small that it should not
receive the careful consideration of the expert designer.
A—Turn Tables
Turn tables are mechanical devices for reducing the turning space required by any automobile to a minimum; that is, to its own length. These are to be recommended only where the conditions of
restricted area require their use, and in northern latitudes where snow and ice abound they should be located only under roof in the garage itself. The width of the space required for the turn table must equal the length of the car, and as the length of an average car is over twice its width, it results in giving up to occasional occupation by the ends of the revolving car a space adequate for the storage of a second car all the time. This is manifestly an uneconomic utilization of cramped quarters. It may be placed before the garage doors, but a turn table in any location is apt to prove too slow in operation, as most autoists are impatient of delay.
Here the turning is accomplished by curving continuously during the forward motion of car until the car is headed back in the direction from which it came.
There are four general considerations requisite
