Abstract

824,970. Spring apparatus. KODAK Ltd. Jan. 16, 1958 [Jan. 16, 1957], No. 1587/57. Class 10. [Also in Groups XIII, XIX, XX and XXXII] A spring 9, storing power to drive a stylus 20 to the left (see Group XIX), urges a plunger 5 towards the end cap 2 of a cylinder 1 and has its rate of release controlled by a fluid, such as silicone oil, which can pass the plunger 5 only through a spiral groove 6, formed in the plunger 5, as shown, or alternatively in the internal wall of the cylinder, in a liner for the cylinder or a sleeve for the plunger.
