Filed: 1925-07-07
Abstract: 254,515. Marks, E. C. R., (Dunhameter Corporation). July 7, 1925. Alarms operated by expansion of liquids; clarms for parts of machinery.-A device for indicating and giving warning of abnormal temperatures of water-cooled automobile engines comprises means for giving differing visible signals at different definite temperatures. A hood 21, Fig. 2, with a window 25 is secured to a cap 10 screwed to the filling spout of a radiator. A grooved and corrugated expansible drum 18 mounted in a sleeve 14 of the cap 10 is provided with a cup for a volatile fluid and carries on its upper wall a rod 23 extending into the hood 21. The rod 23 has a pin and slot connection 31, 32, Fig. 3, with a plaque 26, having its halves differently coloured, and pivoted behind the window 25. The plaque 26 is held with either colour behind the window by a spring 28. In use, a white part of the plaque is normally in view. Upon rise of temperature in the radiator the fluid in the cup 16 expands the drum and raises the rod 23 and moves the plaque slowly until, at a definite temperature, the pin 31 passes the dead centre, when the spring flips the red, warning, part of the plaque into view. The white paint may be luminous for night driving. In another construction, the hood contains an electric bulb and a screen having green and red translucent parts is arranged between the bulb and the window. The bulb is connected through contacts 109, 110, Fig. 12, to a source of supply. When the radiator is below normal running temperature the green screen 87 is opposite to the window and the bulb is not lighted. When the temperature has risen to normal a bell-crank lever 91 operated by the rod 65 of the expansion drum has been rocked so that a contact-plate 115 has bridged the contacts 109, 110 and the bulb is lighted up. Further rise in temperature further rocks the lever 91, tensioning a spring 93 which, when the lever 91 has moved sufficiently to disengage latches 103, 106, switches the screen over so that the red part is between the window and the still lighted bulb.
