PATENT OFFIC CHARLES C. CARLISLE, OF NEAR KAMIAH, IDAHO, ASSIGNOR OF ONE-HALF TO FRANK BOND, OF CHEYENNE, VYOMING.

SELF-ADJUSTING WEIR.

SPECIFICATION forming part of Letters Patent No. 706,526, dated August 12, 1902. Application filed January 4,1902 Serial No. 88,447. (No model.)

T (ZZZ whom, it 772M147] concern:

Be it known that 1, CHARLES CLCARLISLE,

a citizen of the United States, residing near- Kamiah, in the county of Idaho and State of Idaho, have invented a new and usefulWVator-Tight Joint, which is an improvement on the Marseilles module or watemneasuring device.

The following is a brief description of the [O Marseilles module and also a specification of my invention and improvement.

The Marseilles module orwateraneasuring device consisted of a hollow vertical cylinder, which was kept at a constant distance below the surface of the water by a float. The water passed over the edgeof the cylinder and passed out through a channel which connected with the interior of the cylinder. The cylinder passed through a water-tight packing. On account of the friction in the pack ing making the module insensitive its use wasv 0 to move freely without friction and without I leakage at the mercurial joint.

3 5 new water-tight mercurial joint for the water-tight packing and tubular supports to the" floats. These floatsupports being hollow admit air to the tubular weir-below its crest, thus removing all suction from and prevent- 0 ing the tubular weir from acting as an in-* verted siphon, thus insuring uniform discharge. The module as improved by myinvention is shown in the accompanying drawings.

5 Figure l-is a vertical section of the entire module. Fig. Bis a top view or plan of the entire mod 1110.

This module as improved by my invention is described as follows:

to be operated .by'floats.

This invention to- The tube i. telescopes between two vertical 5o tubes at and e, which are fastened together, forming a chamber between them. This space is wider thanthe thickness of the tube 75 andis'nearly full of mercury- The top of the outside tube at is flared so as to form a reservoir o", in which the displaced mercury is stored when the tube tis forced into the chamber between 61 ande. This mercurial joint is water-tight and practicallyfrictionless.

Thefloats f andfare adjustable, so that the top of the tube t may be made to stand at any desired depth below the surface of the water.

0 is a lateral connecting with the main canal.

L is the consumers ditch. 6

The waterflows from the lateral 0 through the tubes, passing out at A into the ditch L, as is shown in Fig. 1. As the tube 25 is operated by floats, the headof watercausing the flow is constant. Hence the discharge into the ditch L is continually the same regardless of the fluctuation of head in the main canal.

I am aware that prior to my invention modules or water-measuring devices were made I therefore do not claim the entire module broadly; but

*What Ido claim asmy invention, and desire to secure by Letters Patent, is

1. The combination of a float, a movable I inlet-conduit suspended from said float, a

My invention relates to the improvement on the above-mentioned Marseilles module or water-measuring device by substituting the fixed -outlet-conduit leading to service telescoping-freely within the movable conduit having a gland or pocket around the extremitieso'f both conduits and aliquid packing of greater specific gravity than water in said pocket.

2. The combination with an automaticallyadjustable inlet-conduit and a fixed outletconduit having a liquid joint between them of an air-duct leading below the crest of the 0 weir into said inlet-conduit substantially as described.
