Fig. 103.—Detail of Brake and Controlling Levers.
[Figures 97], [100], and [103] show
A Simple Control for stopping the car at the different floor levels. Stick S may be a piece of broom-handle, curtain-pole, or flagstaff. Bore a hole through the bottom of the shaft, directly below holes C in the floors (T, [Fig. 100]), and slip the stick through hole T and into slots C. Then locate on one side of stick S points just below the under face of each floor, and upon the opposite side locate points just above where the back edge of the elevator will come when the car is raised to each floor level ([Fig. 97]). Remove the stick, and drill or bore a small hole at each point marked; then replace it, nail a small block (U, [Fig. 100]) across the top end to hold it in place, and drive a nail, with its head filed off, into each of the holes.
When stick S is turned to the position shown in [Fig. 97], while the car is going down, the first nail below the car will project beneath it and bring it to a stop; and if the stick is turned in the opposite direction while the elevator is going up, the first nail above the car will project over the back edge of portion E and bring the car to a stop.
Fig. 104.—An Outdoor Elevator.
Two Levers operate the brakes (W, [Figs. 97] and [100]). Cut these of the shape shown in [Fig. 103], and screw one to each side wall. Then tack a piece of cord to stick S, wrap the ends of the cord once around, slip them through screw-eyes V screwed into the side walls, and tie to tacks driven into levers W.
One series of brakes can now be set by pulling forward one lever, and the other series by pulling forward the other lever. By driving a nail into stick S at X ([Fig. 100]), and a nail into the bottom of the shaft, each side of stick S, the levers will turn the stick just far enough in either direction to bring the brakes into operation.
