DANIEL \V. TROY, 0F MONTGOMERY, ALABAMA.
BQILZNG-INDICATOR F0332 RADLEIQRS.
Specifition of Letters Patent.
Patented May 2, 1916.
application filed May 5, 1915. Serial No. 25,977.
To all whom it may concern Be it known that I, DANIEL W. TROY, a citizen of the United States, residing in the city and county of Montgomery, State of Alabama, have invented certain new and useful Improvements in Boilinglndicators for Radiators, of which this is a specification, reference being had to the accompanying drawing, forming part hereof.
The invention relates to apparatus intended to prevent over-heating of radiators of internal combustion engines of the watercooled type, and the object is to provide a simple, inexpensive and efficient device to indicate to the driver when the water in the radiator of his automobile has reached boiling point, or, within certain limits, other temperatures not far removed therefrom.
The clawing shows all of the elements of the invention.
On a small spindle or shaft, i, i, of some suitable metal, brass, aluminium. the like preferably non-41mrosivel is iiy" fly 2, shown as a simple two-bladcd in having a general reverse cur e formation so as to present to the. observer from practically any position a concave and a convex face. Any type of fly, however, may be employed; that used on anemometers being typical. Shaft l is held loosely in a small tube 3, closed at its lower end and having its upper portion threaded for two on e. In the lower part of the tube 3 and nil-- ing the space between ii: 1 is a fusible material .i, the alloys having a. melting point around degrees Fahrenheit or 'h=.':ly helew. use the apparatus "inst d on the in radiator ap, it being here Y s walls and spindle preferably one of 10 L a hole through the rap and secure 6 3 by the two nu one s ove and one h h the cap, as 'n. the i'ly being e above the rap and or. sed to the lower end of tube 23 r ng within as raera tor where it can be reached by steam. The operation is doubtless obvious. At normal temperatures the spindle 1 is locked by the mass of fusible material and cannot rotate notwithstanding the tendency of the fly as the automobile is driven along. Whenever the temperature within the radiator is sufficiently high to fuse the material 5 the spindle can rotate freely and thus indicate the fact of excessive temperature. No indication is given when the automobile is standing, nor is it required under normal conditions.
I prefer to employ as the fusible material one of the alloys melting at or near the boiling point of Water, and as only a small quantity is employed the spindle is freed very soon after steam is generated. Obviously if desired the lower end of the spindle may be flattened or roughened but this will not ordinarily be necessary as the alloy will hind'it sufficiently against the small torque produced by the exposed fly.
Having described my claim is:
1. In apparatus of the class described, a material fusible near the boiling point of water and exposed to the heat of a radiator, a spindle normally held inoperative by said fusible material, and a wind wheel fixed on said spindle.
2. In apparatus of the class described, a tube arranged to be partly inserted in a ra diator, a material fusible near the boiling point of water in said tube, a spindle normally held inoperative by said fusible material. and a windwheel on said spindle.
witness whereof, I have hereunto set my and, this 3rd no; of May, 1915.
