No. 11 being the high stand, the low stand, and No. 12 the medium height stand forgeneral use. These stands are said to be as nearly ideal intheir simplicity and reliability as is possible to have anymechanical appliance. Fig. 2 is a sectional view showingthe automatic mechanism, which is the same in the threestands. The maker of these switches has introduced a num-ber of safety features into their construction, as will be de-scribed in this article. The spindle to which the target and lamp tip are securedis one solid piece extending through the stand base to the. sure indication that the switch has been completely thrownand locked. The safety block as shown in Fig. 2 is held in position by aroller in an equalizing bar; the latter being held by twosprings. The roller eliminates friction and the safety blockis so shaped as to give the same effective pull on the switchthroughout an entire automatic movement, returning theswitch points to their original position. The safety block is attached rigidly to the spindle by asquare block fitting in the top of it below the lever handle; butwhen the lever handle is raised the square block is raised andthe spindle is then free for operation of the stand by springs on the spring bolts can be tightened or loosenedby putting on or taking off washers back of the nut andcotter, to give greater or less effective strain on the switchpoints according to their length, weight of rail section, insures the switch points always being held snuglyagainst the stock rail, and
