Figs. 104-108.—Details of the Elevator.
Now run the elevator up to the top of the shaft, and mark upon the ceiling where the screw-eye in the top of the car strikes. At this point bore a hole through the ceiling and two inches back of it bore another hole, through which to run the weight-chain. When this has been done, cut a short block of wood to fit the peak of the roof and
Screw the Pulleys to it two inches apart ([Fig. 105]). Fit the block in the peak of the roof, centring the front pulley over the top of the car as nearly as possible, and drive a couple of nails through the roof boards into it to hold it in place temporarily. Then
Attach the Chain to the tack in the top of the car, slip a piece of lead pipe about an inch long over the chain, allowing it to set on the top of the car to make the latter heavier ([Fig. 107]), and run the chain up through the first hole in the ceiling, over the pulleys, and down through the second hole. To the end of the chain attach a piece of lead pipe for
The Elevator-weight (see [Fig. 108]).—This should be just heavy enough to make a perfect balance between it and the car, which can be obtained by whittling off the end of the pipe until the weight of the two is the same. Make the chain of sufficient length so the weight will rest upon the first floor when the car is at the third floor. You can now tell whether or not the pulleys are in the right positions. When they have been adjusted properly, nail the block firmly in place.
The Gable-ends.—The front gable-end consists of four pieces (A, B, C, and D, in [Fig. 109]), the dimensions for the cutting of which are given in the illustration. After preparing these, nail A, B, and C in their proper positions in the gable of the roof, and trim the edges of D, if they need be, to fit between. To prevent the movable section from pushing in too far, it will be necessary to nail a narrow strip of wood to the roof and third floor just inside of it. The rear gable is made in one piece, and is fastened in place permanently.
