The larger illustration shows the application of the brake to the right and left driving shaft of the electric motor on which are two worms, which mesh into two worm gears on the hoisting drum shafts. On the extreme left is the square frame supporting the rheostat for varying the strength of the electric starter. 'he driving shaft Is coupled directly to the motor shaft by a flanged coupling which also forms a brake pull y. The brake arms are suspended at their upper ends from a stud supported upon an inverted V·shaped frame rigidly attached to the base block. The brake arms extend downward below the brake pull y in a straight line, in which are longitudinal slots. The transverse horizontal operating brake lever is pivoted to a stud stand In the space between end portions of the brake arms as shown in the small illustration, and carries friction rollers on the two stud bolts shown on each side of the central stand, which are free to move vertically within the slots. The left nd of the lever Is attached to the lower end of a solenoid operating vertically within an electro·magne1. the ,latter being shown with its connecting wires to the right of the hoisting drum in the large illustration. In the diagram view the operating lever is shown drawn up by the solenoid of the electro· mag- net In thIs position while the curreut is on, which holds the brake arms as wel! as their brake surfaces apart away from the brake pulley. 'hen the operator in tbe elevator breaks the circuit by the usual switch the solenoid drops also the operating lever b. its weight and an adjustable weight attached thereto, bringing the lever into an inclined position (shown by th dotted line) which causes the brake arms to clamp the brake pulley and stop movement of the motor shaft as well as that of the elevator. The general construction of the frame (in tbe large engraving) embodies means of adjustment not usually found in machinery of this class, all the parts being very accessible and convenient in erection or removal in case of repairs.
