7b all whom it may concern. I

Be it known that I, Prune M. Gnria'rr, a citizen of the United States of America, re-

siding at La Crosse, in the county of La' Crosse and State of Wisconsin, have in yentedcertam new and useful Improvements in Indicators for Oihng Systems, of which the followingis a specification, reference being bad therein to the accompanying drawings.

In the operation of engines and power plants, particularly those in automobiles and ower boats, it is desirable-to have means for indicating to the user the operation of the oiling system so that there will be no failure of proper lubrication. Where this indicating means is within range of the operator's Station, it is desirable to avoid the sight of the lubricant itself, as such. construction and disposition necessitate a traus mrent wall inclosing the lubricant. whit-his liable to break and release the oil andrender the operators station not only unsightly but unsafe.

This invention relates to an oil indicator for the power plants of automobiles, boats and the like and for other similar purposes whereby the operator can at once tell that there is a cessation of flow through the system, without there being any back pressure or retarding of the system by the indicating mechanism, while the lubricant itself is not in sight, and there is no danger of breakage or leakage.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings.

Figure 1 is a view of an automobile, partially broken away and indicated diagram martically, and power plant provided with means that embodies Features of the in-. vention;

Fig. 2 is a view in cross section and in detail of the indicator;

F ig. 3 is a view in front elevation ofthe indicator;

Fig. 4 is a view in section and in detail thereof, and

F ig. 5 is a view in perspective and detail of an index andthc operating mechanism.

As herein shown in preferred form a cas' ing 1 that is preferably circular or at least is provided with a suitable dial plate 2, 18 mounted in convenient view of the operators station of an automobile 3 or the like. Preferably the sup )ortin member 4: has an opening throng whiei the casing extendli and wherein it is held by a clamp 5 secured by studs 6 and nuts 7, the clamp cooperating with a fiange 8 which in this instance may conveniently be the marginal portion of a retaining collar 10 that is in screw-threaded engagement with the casing. The dial plate 2 is clamped against an inner flange 11 between suitable gaskets 12, and under -a glass 13 and outer gasket 14 by this retaining eoliarso that the casing is hermetically sealed.

An influx pipe 15 that extends into the casing has an exterior connection 16 suitably arranged for coupling into the pressure or feed side of a conduit of the power plant.

An outlet nipple 17 leads from the casing to the same. conduit so that a flow is maintained through the casing without appreciably filling the latter.

The influx pipe 15 depends from the rear wall of the casing or the side thereof in such manner that it directs its discharge against a. blade 18 that is connected to a spindle 19 extending through the dial plate and carry-- ing an index 20 which sweeps an a propriate scale on the latter. A counterweig t|21 tends to return 'the'blade 18 to initial position. In preferred form the blade 18 is integral with the counterweight member 21, the latter being turned at right angles to the blade so that it moves easily through any lubricant it may encounter.

Consequently, whenever there is movement of oil through the conduit the blade 18 or vane is moved so that the index goes to the on position and the counterweight returns the vane and index to off position when the flow ceases.

Thus the operator can at all times see that how is being maintained throu h the lubricating systeu'i without seeing t to lubricant itself and without any danger of leakage at the point of observation. as the dial plate glass may be broken without releasing the dial plate which seals the casing.

Obviously. changes in the details of construction may be made Without departing from the spirit of my invention and I do not. rare to limit myself to any particular cant discharged from the inlet for indicating moienlent of lubricant from the inlet.

3. An indicator for oiling systems comprising acasing having an inlet and an outlet, a vane pivoted between its ends with one. of its portions in thepatlrof llow from the inlet and the other portion acting as a counterweight to return the vane to initial position, the portions being in transverse planes, and means on the easing for indieating the movement. of the vane.

4. The combination in an automobile having a power plant and oiling system therefor. of an indicator coml'irising a casing having: a dial plate disposed in. View of the operator's station and provided with an inlet for receiving lubricant passing through the T Y fl'lll and anoutlet for returning: it to the system. vane oscillatory in the casing in the path of llnW from the inlet adapted to return to initial position when flow through the casing ceases. and an index moredby the vaneover the dial.

.3. An indicator comprising a casing havinn a tlangn-d owning. a dial plate resting on the flange of the opening and sealing the latter. a cover plate for the dial plate, a collur elamping the dial and cover plate together with interposed gaskets on the flange, an inlet nipple discl'iarging into the casing, an outlet from the casing, a vane oscillatory in the casing in the path of inflow from the inlet. a spindle turned by the vane through a. hearing: in the dial plate, and an index carried by the spindle that sweeps the dial plate.

6. .\n indicator comprising a casing havin; a flanged opening, a dial plate resting onthe flange of the opening, a cover plate over the dial plate, a collar interlocking with the casing. gaskets between the open; inn flange. the plates and the collar, a spindle journaled in the dial plate, a vane .on the spindle in the casing in the path of llow of lubricant into the casing from an inlet thereto, balanced to return to initial position when not, shifted by movement of lubricant, and an index on the spindle traversing the dial plate. t

- 7. An indicator comprising acasing having a flanged opening, dial and cover plates removably and hermetically clamped over the opening, a spindle journaled in the dial plate. a vane having transversely disposed blades. secured to the spindle between the blades, and an index secured to the spindle to sweepthe dial, the casing having an inlet the flow from which impinges against one of the blades of thevane,and an outlet.

In testimony whereof I allix my signature in the presence of two witnesses.
