INDICATOR FOR RADIATORS Filed July 29, 1921 2 Sheets-Sheet 2 Patented June 6, 1933 `PATENT OFFICE HARRY VISSERING, F KNILWORTH, ILLINOIS` l INDICATOR ron Riinm'rons Application filed Ju1y`29,
The present invention relates in general to indicators, andmore particularly to indicators for automotive vehicles and one which is intended to call` attention to and to indicate the state of the water contained within the radiator commonly used in connection with the cooling system of the internal combustion engine. i l
Among the more important objects of the invention is the provision, of a means preferably visible from the driving seat station, for rendering visible indications as to the general state of the` water in. the radiator, ofother means giving more speciiic informa-` tion as to the state and more particularly the temperature of the water, and the embodiment of means of the general character justindicated in a tube `which forms the radia-` tor filling opening, together with such other objects as may be hereinafter pointed out, er may appear. f
In accomplishing the objects referred to and gaining certain advantages to be set forth below, I have provided the structures shown in the accompanying drawings wherein- Figure 1 is an elevational view of one embodiment of the invention;
Figure 2 is a vertical sectional elevational view of the device of Figure 1;
Figure 3 is a horizontal `sectional View taken on the line ,3f-3 of Figure 1; i Figure 4 is a horizontal sectional view taken on the line 4-4 of Figure 2;
Figure 5 is a vertical sectional elevational View of another embodiment of my invention;
Y FigureV 6 is a horizontal sectional view taken on line 6-6 of Figure 5,; o Figure 7 `is a vertical sectional elevational view of-a stillfurther embodiment of my invention; and i p Figure, 8 is `a `horizontal sectional view taken on the line 8-8 of Figure 7. v
Broadly considered, the device includes a perforated casing communicating withY the radiator 4 and provided with a sight opening through which the general state of the water can be ascertained, in combination r `with an indicator from which can be ascertained with comparative `accuracy the ap- 1921. serial No. 488,355.
proximate state of the water. This may be Y secured in the filling opening ordinarily provided in the radiator top and may serve as a tube" 5 throughwhichlwater is supplied to the radiator.`
In the form of device `shown in Figures 1 to`4, the casing, indicated generally at 10, comprises `the outer tube, 11, and the transparent closure member 15. The outer tube 11 is provided with a lower screw-threaded 60 nipple, 12, adapted to' be threaded intothe radiator opening 6, and as here shown is provided with a sight opening, 14, so positioned that it will be directed towards the driver. n
The transparent closure member, 15, is secured in position within the tube 11 against the shoulder,`16, by thespider, 17 (secured by a setzscrew 17 against which spider in turn the screw threaded cap, 18, bears. Upon 70 viewing Figure 2, it will benotedthat the transparent member, 15, which `is convenientlytubularin form, is closed save at its open ends, and that such ends are sealed to prevent leakage around the periphery of the tube, 15,
by means of the washers, 19 and 20, interposed between the tube'and the shoulder, 16, and the tube and the spider, 17, respectively. The overflow tube` 27 of the radiator is, for the purposes of my invention, extended up- S0 wardinside of the casing 10 to the upper portion of said casing.
In the use of the structure thus far described, it` will be observed that should the water in the radiator heat up, this fact will become apparent at the sightopening, 14, by the presence of vapor or bubbles arising due to convection currents, or the precipitation uponthe inside of the transparent tube of water of condensation.
It will be readily appreciated that such an emanation from the surface of the water in the radiator may be sufficient as a warning of high heat conditions, but may be inadequateto present the desired more explicit in- ,95 .formation aste the approximate temperature of the water.
Tomeet this situation I have, therefore, provided a secondindicator inthe nature of temperature responsive element, such as a through the vapor, bubbles or water of condensation are in a sense indications by convection currents, whereas the'ther'mometric indications are indications by heat conduction inasmuch as the lower portion, 26, of the thermometric device is in communication with the radiator.
It is well :known that upon heating a portion of liquid a'vapor is given on which due to being of greater temperature than the surrounding air will rise, and in the present instance, enters the closure member thus creating convection currents lwhich continue so long as the difference in temperature referred prevails for the reason that the heated vapor rises and the closure being cooler produces water of condensation which continues the production of convection currents so that an indication as to the state of the water in the radiator is made. A
With reference now more particularly to the device of Figures 5 and 6, it will be perceived that the structure herein shown al'- though similar to that of Figures' 1 and 2 differs therefrom in certain respects. Among the primary features of difference are the following :that the thermometer, 21a, is support-ed eccentrically of the casing, general-ly indicated at a, the upper end being loosely carried in a socket in the spider 17a and has its bulb portion supported on the pin 23a, which is carried by a sleeve, 24a, shown as integra-l with the screw-threaded nipple, 12a', and that inorder to provide for' more light and hence not only greater' illumination of the interior of the casing', 10a, but also to render the indicator readable from more directions, as well as more easily, I have'provided tube, 11a, with an increased number of sight openings, 14a, four thereof, spaced 90 apart being illustrated inthe drawings, thus giving the tube, 11a',y a spider-like crosssection clearly to be seen on reference to Figure 6. The cap 18a' corresponds to cap 18 of Figures 1" and'2. The overflow tube 27a of the radiator is, for the purposes of my invention, extended upward inside of the casing 10a into the' pocket 28a'provided in spider 17 a.
In the further embodiment of my invention shown in Figures 7 and 8, the transparent portion, b, of the casinggenerally indicated at 10b, is fixed in position externally of the tube, 11?), instead of internally thereof, and is held in position between the washers, 19?) and 20o, by means of the bearing ring, 336, and the'cap, 18?), which in the present instance, is internally threaded for engagement with the upper' end of the tube, 11b. The thermometer, 2lb, has its bulb portion sustained by the pin, 23?), mounted in the sleeve, 24?), preferably integral with the screwthreaded nipple, 12o, and has its upper end socke'ted iin boss, 3422, integral with the upper end of the tube, 11b, the function of the spiders, 17 17a',- being performed by the bearing ring 33o. The overflow tube 275 of the radiator is, for' the purposes of my invention', extending' upward inside of the casing 10?; to the' upperlportion of said casing.
