LIQUID-MEASURING GAGE.

Specification of Letters Patent.

Application filed April 22, 1915. Serial No. 23,247.

To all whom it may concern Be it known that I, Josnrn C. Brown, a subject of the King of Sweden, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Liquid- Measuring Gages; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to liquid gages and more particularly to a device for indicating the depth of liquid in gasolene tanks of automobiles or motor-boats.

The primary object of the invention is the provision of an indicating device mounted in a cap which may be applied to the filling opening of any tank so that the formation of additional openings through the walls of the tank is rendered unnecessary and which is simple in construction so that it may be applied at small expense.

With the above and other objects in view the invention resides in certain novel features of construction and combination and arrangement of parts as will be more fully described and claimed.-

In the accompanying drawings :Figure 1 represents a side elevation of a portion of a tank equipped with this improvement; Fig. 2 is a longitudinal vertical section thereof showing the gage in locked operative position; Fig. 8 is a detail sectional view of the cap with the gage bar in lowered position; Fig. 4: is a plan view thereof.

In the embodiment illustrated a gasolene tank 1 is shown which may be of any preferred or desired construction and which is 40 provided with an enlarged mouth or filling opening 2 internally threaded to receive the closure carrying the indicator bar to be described.

The closure constituting this invention comprises a cup-shaped cap 3, the side walls of which are threaded as shown, at 4 to adapt it for threaded engagement with the mouth 2. This cup is provided at its outer edge with alaterally extending ,fiange 5 which is adapted to project beyond its side walls and, when the parts are assembled, to rest on the outer edge of the mouth 2 as is shown clearly in Fig. 1. This cup-shaped cap has an upright reinforcing rib 6 extending diametrically thereacross and provided at its center with an opening 7 extending through the cap Patented Sept. 19,1916.

and rib, and which is here shown angular in cross section. A tubular member 8 depends from the dower face of the cap 3 around the opening 7 therein, and the cross sectional contour thereof is shown corresponding to that of the opening 7 both of which are shown angular and which are designed to receive and guide the vertical indicator bar 15 which is also angular in cross section but they may be of any other shape. The rib 6 on its upper edge midway of its ends and around the opening 7 therein is provided with a notch or seat 9 which is designed to receive theupper end of the bar 15 when the bar isv in its extreme inner position, said end having a cotter pin 10 or similar stop member extending transversely thereacross to prevent it from being drawn through the opening 7 when it is so disposed. This cotter pin is housed in the seat 9 and is designed to be held therein when the gage is not in use, by a locking bar 11 which is pivotally connected at one end to the rib 6 at one side of the seat 9 therein, and is of a length sufficient to span said seat and extend some distance beyond the opposite side thereof. This bar 11 is provided at its free end with an upturned handle 12 for shifting the bar. laterally to cover or uncover the seat as may be desired, or this bar may be fastened by any other means.

Projecting inwardly from opposite sides of the rib 6 on the side of the seat opposite that which carries the locking bar 11, are two lugs 13 and 14: between which the free end of the bar 11 is designed to be positioned and held thereby in looking engagement with the bar extending over the seat 9 and over the end of the indicator bar 15 as is shown in Fig. 4 and whereby said bar is locked in its retracted position to hold it out of the way when not in use.

A float 16 is secured to the lower or inner end of the bar 15 by any suitable means and said float is here shown of less diameter than the diameter of the opening or mouth 2 to provide for its ready insertion and re-.

moval through said mouth.

As shown. the indicator bar 15 extends tl'irough the float 16 and said float is held in engagement therewith by two cotter pins 17 and 18 which extend transversely through the bar 15 at points above and below said float although it is obvious that any other suitable means may be employed for fastening the float to the bar.

Normally the parts will be held in the position shown in Fig. 2 with the locking bar extending across the upper end of the indicator bar, whether the tank is full or empty, and whereby the float 16 will be held submerged. If, however, it is. desired to ascertain the depth of the liquid in the tank, the bar 11 is disengaged from the lugs 13 and 14 and swung laterally from overthe seat 9 thereby liberating the indicator bar 15 so that the float 16 will rise to the surface of the liquid and lift the bar 15 to a height corresponding to the depth of the liquid in the tank, said bar 15 being providedwith graduations to indicate the depth of the liquid as will be obvious. Vhen the depth of the liquid has been ascertained the bar 15 is pushed down with its upper end disposed in the seat 9 and the locking bar 11 is swung over said end and held against lateral movement by the lugs 13 and let.

I claim as my invention A measuring gage of the class described comprising an externally threaded cupshaped cap for attachment to the filling opening of 'a tank, an-upri ht rib extending diametrically across the upper sideof said cap and having a notch in its upper edge midway the ends thereof, said cap and said rib having a vertically extending passage therethrough, a. locking bar pivoted to the upper side of said rib and having its free end upturned, said bar being of alength suflicient to span said notch, a vertically slidable indicator bar mounted in said passage and having a stop member at its upper end received'in said notch, the upper end of said indicator being disposed beneath said locking bar when. the latter is inv its operative position, and a float at the lower end of said indicator bar.

.In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
