The works should now be attached to the wooden frame. Place them with the striker uppermost, near the edge of the frame, so that the small belt-wheels are in line with one another. Then bore a number of gimlet holes in the wooden frame and run copper wire through. them, passing it around the posts of the clock-frame and twisting its ends until the works are firmly fastened in place.
A rubber band about an eighth of an inch wide and long enough to reach from one belt-wheel to the other should be procured for
The Belt. This should stretch just enough to cling upon the spools, as more than that would cause too much friction.
Before going any further with the construction of the automobile
Test the Machine, to be sure that it is in perfect running order. Wind up the mainspring, pressing a finger against one of the wheels to hold it in check until you are ready to start the machine. When properly made, the clockwork automobile should run a distance of from twenty to twenty-five feet upon a wooden floor, while about three-quarters of that distance should be covered upon a floor with a fairly smooth carpet.
The Cardboard Sides and other details of the automobile should now be made. The patterns for these have been so shown in Figs 163 to 170 that they can easily be laid out to the proper shape and size by means of the pro-
