Further objects and advantages of the invention will be set forth in the detailed description which now follows:

In the accompanying drawing,

Figure 1 is a perspective view of an apparatus partly broken away, embodying the features of the invention.

Fig. 2 is a horizontal, sectional view through the indicating mechanism illustrated in Fig. 1,

Fig. 3 is a rear perspective View of a modified form of the indicating mechanism, and

Fig. 4 is a fragmentary front view in perspective of a part of the indicating mechanism illustrated in Fig. 3.

Like numerals designate corresponding parts in all of the figures of the drawing.

In the drawing 5 designates a galvanized sheet metal box having a closed bottom; an end 6 of which box is provided with an orifice 7. 8 designates an adjustable gate that is carried by a strap 8*, said gate serving to close or partly close the orifice 7. The orifice 7 is six inches deep by twenty four inches long and the gate serves to adjust it to any of the following izes:

3 Patented Mar. 12,1918. a, r917} Serial No. isten adjustment by a pin 10 that is adapted to enter'any of the holes 11. The strap is protitled with an operating handle 12. I A "like strap 13 carries'al'ioperating handle M 'and [selves to adjustagate 15 overthe mouth of d schargepipeltifi The st'rap13 slides tliro'ugh 'a bracket- 17 and held in varying positions of vertical -aldjiistin'ent by pin" 18.

So far the parts are o'f substajntially' 'the same character as thosedscribedinmy copending application aforesaid. Secured to 'theo'uter face of the box 5' are' stilling Well pipesao and 21 having the fioat s' 22 and 23 therein. These floats are connected to rods '24 and 25; respectively; *The rod 25 carries a's c'ale'26: and therod 24 carries a pointer 27 which operates over the scale. A 'k'per gag'es over anedge of the A scale 2'6 to hold the parts in cooperative relation. The stillingwell" pipe'20 has an opening "29 formed in its bottom which permits water from the canal outside of the box to rise in the stilling well pipe 20 to the level of the water in the canal. The stilling well pipe 21 upon the other hand is in communication with the interior of the box 5 through an opening 30 so that the height of water within the stilling well pipe 21 will be at the level of the water within the box 5.

It is to be noted that the graduations upon the scale begin at the bottom and extend upwardly and since it is the relative height of the water inside of the box 5 and in the canal outside of the box that indicates the rate of flow it follows that this arrangement of parts Will result in accurately indicating the rate of flow of the water because if the float 22 rises it causes the pointer to indicate a higher number While if the float 23 falls this also causes the pointer to indicate a higher number.

In the modified form of indicating apparatus illustrated in Figs. 3 and 1 the same reference characters have been applied to the stilling well pipes. In this case, however, the rod 2 1 which corresponds to the rod 24 carries a shield 25 and this shield is slidably disposed upon a plate 26 that is carried by rod 25*. The shield is provided with a sight opening 25 through which certain numbers carried by the plate become visible as the shield and plate move vertically with relation to each other and it is to be understood that these numbers serve the same pm:-

pose in this relation that the graduations upon the scale 26 serve with relation to the construction illustrated in Fig. 1.

It is to be noted that the discharge pipe 16 is located higher than the orifice 7 so that the orifice 7 is always submerged when water is passing through the discharge pipe.

' which of said figures appear through the sight opening 25,

Having described my invention what I claim is:

1. The combination with a receptacle, of

a pair of stilling wells one of which has communicatlon with the Water outside of the receptacle and the other of which has com munication with the water inside of the re ceptacle, rods movable in said stilling wells, a float movable in each of said Wells by which said rods are carried, a scale carried neaasev by one of said rods and a the other of said rods.

2. A structure as recited in claim 1 in which means are provided for guiding the scale with respect to the pointer and vice versa.

pointer carried by 3. A. structure as provided in claim 1 in which the scale is provided with indicating members extending from the bottom upwardly.

4. An indicating mechanism of the character described comprising a pair of rods, a shield carried by one of said rods, a plate carried by the other of said rods and slidable within said shieldand indicating members upon said plate.

' 5 A. structure as recited in claim 4 in which the shield is provided with a sight opening the indicating members upon said plate becoming successively visible through the sight opening of the shield during the relative movements of the shield and plate. In testimony whereof affix my slgnature in the presence of two wltnessesu PERRY E. BURNHAM.
