Temperature Activated Fixture

These metallic fixtures are manually assembled with ease and then used in a process which subjects the fixture to an elevated temperature. The strategic placement of metal members having a high-temperature coefficient of expansion tightly closes the fixture.

The main body of both fixtures includes two similar shaped metallic members 10 and 11 which define a cavity. In the fixture of Fig. 1 this cavity 16 is open at both ends. The fixture of Fig. 2 includes an internal cavity, not shown. These members have mating surfaces which meet at plane 12. Member 10 includes a number of aligned holes 13 which receive positioning posts, not shown, carried by member 11.

In the fixture of Fig. 1, members 10 and 11 include four side channels which loosely receive four I-shaped links 14. The four corners of each of the channels include a metal member 15, fixed to members 10 and 11. Members 15 have a high-temperature coefficient of expansion. The ambient temperature dimensions of the various fixture parts are such that links 14 can be easily positioned in the side channels, as shown.

In the fixture of Fig. 2, member 11 carries two pivoted arms 16 and 17 which serve the function of the links 14 shown in Fig. 1. Member 10, in Fig. 2, includes four projecting lugs 18 whose interface with arms 16 and 17 includes members 19 having a high-temperature coefficient of expansion. Member 11, in Fig. 2, also includes four projecting lugs 20 whose interface with a...
