Humane, a at Be it known that L'HENRY citizen of the United States, residin Seattle, in the county of King and of \Vashington, have'invented certain new and useful Improvements in Liquid-Level Indicators, of which the following is a specification.
This invention relates to 11 uid gages, and
is'desi ned, more particular y, for use on automdbiles to'indicate the depth "of lubri-f catingoilinthe crank casing.
' The. object of'n y invention is the provision of a novel" sight gage and controlling appliances therefor to indicate to the dr ver of an 'automobile the amount of lubricating A further and. important object ofthe invention isthe provision-of devices for regulating the referred to controlling appliances to compensate'for expansion and contraction due to change of vternper- Nature. .7 I
of the fluid agent a In the accompanying drawings, Figure l to. Figs. 2 and 3 are longitudinal. vertical.
1 is a side elevationsliown partlyvbroken away of an automobile engine with: apparatus en bodying the present invention applied there- I sections of the lower and upper portions of my improved apparatus with associated parts of the engine andv automobile body.
The. reference numeral 5 designates the dash-board of an automobile, and 6 is the engine havinga chamber 7 within its so.-
called fly wheel casingS. This chamber should containfla sufiici'ent quantity offoil to extend toa level somewhere between openings 9 and 10, Fig. 2, Whichare usually provided with pet-cocks, such as 11.
In carrying out my invention, the cock for the lower opening- 10 is omittedand inf lieu thereof is inserted a nipple 19, whose outer end screwed. into a cylindrical open top vessellii and servingto support the latter.: Said nipple thus affords communication between; the lower end or said vessel and the interiorof the casing 8 whereby it evident that the liquid siirfaces in both the vessel andsaidjchainber are in the same horizontal :plane.

sci, and also serveswitn respeqtto, th ef-pe ripheral wall 13 of saidv'cssel I toguldefxf the innerwall 15 of the cover substanti l izl n,
in axial alineflient with the vessel. The wall 15, in eifect, serves as an extension to the flexible tube and will bethus designated in the following description which I will now make of the operation of the invention.
Assumin that the oil in the vessel is at a level in icated by line yy in Fig. 2 (which corresponds with that in the casing 8) when the cover 14 is raised through the instrumentality of the wire 31 into approximately its dotted line position 14; under such a condition the lower edge of the tube extension 15 will be in a plane denoted by 14 to allow a free passage of air into the chamber 19. The extension is then lowered or pushed down by the operator through the medium of wire 31 into full line position, Fig. 2.
When this occurs, the air confined within the chamber, 19' and within the receptacle 21 is subjected to pressure exceeding that of the atmosphere, which acts against the indicating liquid 22 within the glass tube 25, resulting in the liquid being forced down in the receptacle 21 and correspondingly elevated in the glass tube. The elevation of the liquid in said tube, as denoted by the graduation marks on the rod 27 should indicate the depth of oil in the flywheel casing 8.
When the engine has, however, been operated for some time, and because of the apparatus being exposed to the heat radiated from the engine, the apparatus will he more or less afiectcd thereby.
The air within the tube 20 and in the members communicating therewith will thereupon expand to exert an abnormal pressure upon the liquid 22' in the recep tacle 21 to unduly raise the indicating liq uid in the tube 25 to give an incorrect read-' ing on the rod 27 as to the oil level in the casing 8.
To overcome such an occurrence, the operator has with the present invention only to pull up'the tube extension throu 11 the medium of the wire 31 so as to ena Ie the excess air pressure to be reduced by aifordin communication between the chamber 19 am the exterior atmosphere. Suchequaliziug of pressures, however, exists only while said extension is held above the oil level, as the air pressure within the chamber 19 "therefrom.
vessel containing oil, a
.oil, a receptacle, 'ing at its upperv end with increase during the lowering of the cover wall ,15 in the oil, but only to an extent to which the rod 27 is adjusted with respect to the quantity of indicating liquid, or vice versa.
What I claim is 1. In apparatus of the class described, the combination with a stationary vessel containing oil, of a receptacle secu ed at a higher elevation than said vessel, a gage glassconnected at its lower end to the lower end of said receptacle, a gage-rod provided in the glass tube, an indicating liquid partly filling the receptacle and said glass tube, a flexible tube connected at one end to the upper end of said receptacle, an extension at the other end of the flexible tube, and means for regulating the elevation of said extension, for'submerging the same in the oil within said vessel or withdrawing it will progressively 2. In apparatus of the class described, a vessel containing oil, a receptacle and a communicating glass tube partly filled with an indicating liquid whose elevation in the tube is discernible through the latter a flexible tube having an extension submer -ed in the oil and its other end connected with the space above the indicating liquid in said receptacle, and means to temporarily withdraw said extension t'rom the oil.
In apparatus of the cover therefor having a chambered portion extending into said a glass tube communicatthe external atmosphere and at its lower end. with said receptacle, said receptacle and tube being partly filled with an indicating liquid, :1 tube connecting the upper part of the chamber in the referred-to cover-portion with the space above the indicating liquid in said receptacle, and means for elevating and lowering said cover whereby the chambered portion thereof may be witi drawn from or introduced into the oil contained in said vessel.
