Lay out the two assembly drawings as shown in Fig. 11-45 or 11-46. Complete the drawings from the information supplied below, and make detail drawings of the springs. Use your judgment for sizes not given. For Fig. 11-45:
• Assembly A. The license plate holder is held to the frame of the car by a hinge. A torsion spring is required to keep the plate holder in position. The torsion spring is slipped over the hinge pin during assembly, and one end of the spring passes through the hole in the bumper. The other end of the spring is locked into the spring-retaining notch in the license plate holder. Scale 1:2.
• Assembly B. Flat springs are positioned in openings C and D in the tape deck player. These springs hold the cassette against the bottom and the locating pin positioned in the left side of the tape deck. Scale 1:2. For Fig. 11-46:
• Assembly A. An extension spring controls the lever. The spring is fastened to the neck in the pin and through the hole in the lever. Scale 1: 1.
• Assembly B. A compression spring mounted on the shaft of the handle provides sufficient pressure to hold the lever in position, thus maintaining the door against the panel. To open the door, the handle is pushed in and turned. This action compresses the spring and forces the lever away from the notch in the panel edge, thus permitting the lever to turn. Scale 1:1.
