SPECIFICATION forming part of Letters Patent No. 781,093, dated January 31, 1905.
Application iiled February 16, 1904. Serial N0. 193,901.
ing or deiiecting a uniform quantity of water from a lake, stream. canal, irrigating-ditch, or for effecting the uniform iiow of oil, chemical, or other liquid from a reservoir or other sourc of supply.
rIhe improvement seeks to provide simple, lnexpensive, andefiiclent means whereby a yconstant uniform iiow may be deiiected from the source of supply over a suitable iioating vweir which responds to changes in the waterlevel of such supply and whereby leakage between the moving and stationary parts is prevented without interfering 'with the delicacy of flotation of the weir and the accurate regulation of the iiow.
` The invention consists in the features and combinations of parts hereinafter set forth, illustrated in the accompanying drawings, and
v vmore particularly pointed out in the appended claims.
In the drawings, Figure 1 is a sectional elevation ofthe improved apparatus. and 3 are similar views illustrating modifications of' the invention. i
The apparatus may be placed directly in the reservoir 10 or other source of liquid-supply, but which when measuring water preferably forms a penstock or water-bay into which the water from the canal or lake has free access.
- The well 11 opens into the bottom of the resuring notch or Weir 14. Inner and outer weir- Figs. 2 i
The inner and outer Weir-.pipes 15 and 1.6 extend, respectively, within and outside of the fixed discharge-pipe 12, but are spaced away from and looselyfit said discharge-pipe, so that the weir and the connected pipes are free at all times to respond to any change in the liquid-level of the source of supply.
The upper ends of the Weir-pipes lare connected to form an air and liquid tight sealingchamber 17, closed at its upper end and so arranged that a liquid seal is maintained lbetween the fixed discharge-pipe and the movable Weir-pipes.
When the apparatus is in operation, the column of liquid in the inner Weir-pipe 15 will force/liquid up into the sealing-chamber 17 between the pipe 15 and the discharge-pipe 12, so that the air in the sealing-chamber is maintained under pressure. The air-pressure thus maintained in the sealing-chamber `17 will prevent thel water rising' into the chamber between the outer weir-pi pe 16 and the discharge-pipe from reaching the level of the upper end of the discharge-pipe and overflowing into the same. In this manner a freelysliding or practically frictionless liquid-sealed joint is maintainedlbetween the movable weirpipe and thev fixed discharge-pipe to insure To insure that no leakage will occur through the sealing-chamber, the outlet 18 of the discharge -pipe is extended upwardly, as indicated, a considerable distance above the lower endof the inner Weir-pipe 15, so that even 4 when the flow of liquid through the apparatus is slight a constant level is maintained within the pipe 15. The column of liquid thus maintained in the pipe 15 Will holdy the Ioo air in the sealing-chamber 17 under sufficient pressure to prevent any leakage of liquid through the sealing-chamber and over the upper end of the discharge-pipe. In this inanner no liquid can pass through the apparatus except that flowing over the measuring-weil', and at the same time great freedom of movement of the {ioating parts is permitted and accuracy of regulation of the flow maintained. Moreover, the sealing-chamber 17 acts as a float for sustaining the movable parts of the apparatus, and iioats 13 may be omitted. The Weir-box is, however, preferably provided with means for receiving adjusting-weights. The lengths of the vertical inlet and outlet ends of the discharge-pipe and of the weirpipes are suiiicient to permit the proper operation of the apparatus between the highest and lowest levels in the reservoir or other source of supply and to maintain sufficient air-pressure in the sealing-chamber to prevent leakage therethrough in all positions of the floating weir.
Leakage through the sealing-chamber may also be prevented without interfering with the delicate iiotation of the weir by lilling the space between well 11 and discharge-pipe l2 with mercury, (indicated at 19 in Fig. 2,) which cannot be displaced by the overlying column of liquid in the bay or other source of supply because of its high specific gravity. In this arrangement, as indicated, the inner Weir-pipe and the upturned end oi' the discharge-pipe may be omitted.
If the apparatus is employed in connection with a deep reservoir, as 10', (see Fig. 3,) the inclosing well 11 may be omitted. It is obvious that other changes may be made in the arrangements of parts and in the details of structure Without departure from the essentials of the invention.
Having described my invention, what I claim las new, and desire to secure by Letters Patent. is*
1. The combination with the discharge-pipe, of a ioating weir-pipe communicating therewith and means for maintaining a liquidseal between said pipes.
2. rlhe combination with the iixed discharge-pipe, of an open-mouthed floating Weir-pipe loosely fitted to said discharge-pipe and movable relatively thereto and means for maintaining a liquid seal between said pipes.
3. The combination with the iixed discharge-pipe extending from the source oi' liquid-supply, of a pipe for receiving water from the supply communicating with said discharge-pipe and movable relatively thereto, a measuring-Weir at the upper end of said receiving-pipe, a lioat for sustaining said receiving-pipe and weir and means `for lnaintaining a liquid seal between said pipes.
L1. The combination with the discharge-pipe, of the movable inner and outer lloating weirpipes extending respectively within and outside of said discharge-pipe, said Weir-pipes being connected to form a closed-topped sealing-chamber.
5. The combination with the discharge-pipe extending upwardly within the reservoir from which the liquid is drawn, of movable inner and outer pipes connected to form a closedtopped sealing-chamber and extending respectively within and outside of said discharge-pipe, a measuring-Weir at the upper end of said movable pipes and a iloat supporting said weir and said movable pipes.
6. The combination with the discharge-pipe, of the movable, inner and outer floating weirpipes connected to form a closed-topped sealing-chamber and extending respectively within and outside of said discharge-pipe and means for preventing leakage through said sealing-chamber.
7. The combination with the d ischarge-1' ipe of the movable, inner and outer lloating weirpipes connected to form a closed-topped sealing-chamber and extending respectively within and outside of said discl'iarge-pipe, the outlet end of said discharge-pipe extending upwardly above the lower ends of the inner weirpipe to prevent leakage through said sealingchamber.
S. The combination with the well, ol a discharge-pipe extending upwardly within said well, a movable pipe litted loosely between said well and said discharge, a lioat and a measuring-weil' connected to the upper end of said movable pipe and means for preventing leakage through said well and between said pipes.
9. The combination with a well arranged to communicate with the source of water-su pply', of a fixed discharge-pipe extending uliwardly within said well, movable inner and outer pipes extending respectively within and outside oi' said discharge-pipe and connected to form a closed-topped sealing-chamber, a measuring-Weir at the upper end of said movable pipes and discharging into said inner pipe, a float for sustaining said weir and said movable pipes and means for preventing leakage through said sealing-chamber.
