Application filed August 1%,1916. Serial Elle. li ifiS t.

of Washington, have invented certain new aml-usefnl Improvements in l loa't'Operated Indicators; and I do lowing to be a hereby declare the folfnll, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appcr-' tains to make and use the same. This invention relates to float operated in dicators of the type particularly designed for use in connection with explosive engines for indicating the quantity of oil contained in the crank case.

The invention has for its object to provide an improved indicator including a float housiu which is suspended tromthe upper Dart oi the crank case of the engine and is entirely independent of the bottom part so as to permit the latter to be readily removed when necessary.

Another object is togenerally improve and simplify indicators for explosive engines and render them practical and eiiicient and also readily adaptable explosive engines.

With these and other objects to numerous types oi in View, the

invention consists in the novel construction,

combination and arrangementof parts as will be hereinafter specifically described;

claimed and illustrated in the accompany ing drawing, in which: I

Figure 1 represents a side elevation of an explosive engine, partly in section, illustrating the improved indicator applied thereto,

Fig. 2 represents an enlargediragmentary sectional view through the crank case oi" the engine, illustrating a portion of the indicator in detail g Fig. 3 represents an elevation of the indicating part of the indicator,

Fig. t represents a front elevation, similar to Fig. 3, illustrating a modified type of the indicator, and

Fig. 5 represents a longitudinal sectional view through the upper terminal of the bendable guide for the flexible operating element.

Referring to the drawing in detail, wherein'similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates generally a well known type of explosive engine including the usual upper and lower crank case sections 6 and 7, respectively, the lower section 7 being detachably secured to the upper section 6 in order that access may be had to the connecting rod and crank shaft hearings.

in the accompanying drawing the invention is shown as applied to a motor vehicle, the dash board 8 of which is represented in The improved indicator comprises a float housing 9', having oil ports 10 adjacent the lower end and an inwardly directed flange 11 fori'ned at the lower edge thereof to prevent the float 12, which is arrangedwithin the housing from dropping therefrom when the bottom section 7 of the crank case is removed. The flange 11 of the housing simply rests upon the bottom section of the crank case and is entirely independent thereof so to permit the bottom section to be detached independently of the float housing.

A cover 13 is removably fitted over the upper open end of the housing 9 and is formed with an integral, flange 14;, which is rigidly and permanently secured to the lower terminal of a tubular guide 15. The guide 15 preferably formed of bendable metal and. is extended upwardly through an aperture the top part 6 of the crank case.

it ring 16 is fastened to the top section 6- and is formed with an integral flange 1'? receiving the tubular guide 15. A set screw 18 is fitted in an internally screw threaded aperture formed in-the flange 17 and engages the tubular guide 15 whereby the housing 9 is suspended from the top crank case seclion. and is held in position afterthe removal of the bottom crank case 7.

The tubular guide 15. is extended to the dash board or other convenient point upon the motor z 'chicle or other object and is connected with a tube 19 having a slot 20 there in. A sight glass tube 21 is confined in the tube 19 between the terminal of the guide 15 and a plug 22 fitted in the upper end of the tubefli).

A stem 23 is connected with the float it), extends upwardly within the lower terminal of the guide 15 and is rigidly secured at its uppe terminal with the the flexible actuating member 24. The opposits terminal 0? the flexible member Q4 is adjacent end oi too extended into the transparent tube 21 and is the slot 20 in the; tube l9,

and may housed or referred to in connection with markings on a plate 26 fastened in venting displacemen front of the tube 19 to indicahe of oil contained in the lower crank case. .i

in the modification of the invention illustmted in Fig. 4 the end of the flexible men with arod 27, having at the quantity section 2 of the eer 24 is connected line marked thereon adapted to he read in connection with the markings on the plate 26 to accurately indicate the quantity of oil in the crankcase of the engine. fWhat I claim is:'' 1. In combination, ed for use .in connection with an engine crank ease of the sectional oil-containing type comprising an upper and a lower section, en actuating float for the indicator and adapted for location in the crank case, a housing for said float havir g an apertured lower terminal, an inwardly directed flange at the lower terminal of the housing, preof the float and conan oil indicator adaptet woe base anhzptuxi "to mow bottom of the lower section 11k case, and means for adjustubly i l gthe housing from the upper section of thecmni; case independently of the lower section thereof.

2. in eomhin' on, an engine provided with a crank case, said crank case including an upper section and :1 lower section detachahiy secured thereto, and an oil. indicator suspended from the top crank case section and being independent of the lower detache-hie section, whereby the latter may be removed independently of the indicator to ma pose the internal mechanism thereof.

In testimony whereof I affix my signature in presence of a witness.

GEORGE G. BELDEN.
