Abstract
893,170. Inertia switches. ROBERTSHAWFULTON CONTROLS. Oct. 16, 1958, No. 33082/58. Class 38 (5). [Also in Group XIX] A device sensitive to a wide range of accelerations consists of a mass 105 mounted on the end of rods 107 pivoted by means of a leafspring 109 between blocks 108, 110, a magnet 112 attracting the mass 105 and a spring 122 tending to turn mass 105 away from the magnet. When the acceleration of frame 102 reaches a certain value, determined by the adjustment of spring 122, the mass 105 moves away from magnet 112 towards magnet 113, lever 117 applying pressure to the operating pin 119 of a snap switch 120. The mass 105 can be returned manually to its initial position by means of plunger 131. The gravitational force on the device is predetermined by finding the setting of the spring 122 at which the device will actuate without any external acceleration, which setting is then taken as the zero setting. The device may be used as a peak accelerometer, or for actuating a warning system or shutting down a machine when excessive vibration occurs. A modification of the device which responds to vibratory acceleration at a given frequency has a further mass connected to mass 105 by means of a leaf-spring (Fig. 5, not shown). The device is then only actuated when the required acceleration occurs with the resonant frequency of the modified system.
