Title: Improvements in stress strain recording mechanism for use in connection with machines for testing the physical properties of materials
IPC: G01B7/16
Filed: 1948-11-20
Abstract: 660,210. Testing physical qualities. AVERY, Ltd., W. & T., and BINNS, A. Nov. 20, 1948, No. 30205/48. Class 106 (ii) Extensometer of the type having a pair of electrical contacts opened by extension of the test piece in which the opening of the contacts actuates a ratchet type relay which imparts a predetermined rotation to a micrometer screw to close the contacts, and a second relay imparting a proportional predetermined rotation to a recording means. When the test piece 1 extends under load the contacts 2 are opened, thus de-energizing the relay 4 to effect a closure of the contacts 5 and energize the relay 6 which in turn closes contacts 7 and 8, thereby energizing the relay 9 to close contacts 10 and effect a progression of the ratchet-wheel 12. Closure of the contacts 10 energises the relay 13 to operate the ratchet wheel 16 connected to the recording drum and opens the contacts 14, de-energizing the relay 6 and allowing contacts 7 and 8 to open. If the progression of the ratchet-wheel 72 has been sufficient to close the contacts 2 the same sequence of operations is repeated only when the contacts 2 are re-opened by further extension of the test piece. If the progression of the ratchet-wheel 12 has not been sufficient to close the contacts 2 then the sequence of operations is repeated immediately, thus effecting a further rotation of the micrometer screw 3 until the contacts 2 are closed.
