AUTOMATIC WATER-DISTRIBUTER.

SPECIFICATION forming part of Letters Patent No. 327,141, dated September 29, 1885.

Application filed March 25, 1545.5. (No n iodel.)

To 1f/ZZ whom it' may concern:

Be it known that I, JOSEPH CORNELL, a citizen of the United States of America, re siding at Petersburg, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Automatic VVater-Distributers, ofwhich the following isa specification, reference being had therein to the accompanying drawings.

This invention relates to apparatus for water-distribution for irrigation and other purposes; and it consists in animproved device for regulating the fiow of water, as hereinafter described and claimed.

In the accompanying drawings, Figure l is a plan View of a penstock provided with my improvements. Fig. 2 is a longitudinal vertical section taken ou line n: x of Fig. 1. Fig. 3 is section taken on line ,e a, Fig. l. Fig. 4 is a front elevation of the penstock. Fig. 5 is a rear end elevation. Fig. 6 is a perspective of one of the inlet-passages.

The object of my invention is to furnish a device which will regulate the flow of water through a penstock or other conduit, so that the same shallbe uniform andnnvarying, and shall be equally delivered to the several irrigatingchannels whether the main stream supplying the water is either high or low. I attain these objects by means of the followingdescribed devices.

A designates the casing of apenstock. C O are sand-boxes, the forward ends of which'extend through and are fitted closelyin openings in the front wall of the penstock, and are provided with the inlet-gates B B. These sandboxes are extended backward, and are provided with the exit-openings b near the rear in the penstocl,for the purpose of conducting all the water entering the penstoclr through the boxes to the rear,whence it turns and runs forward to the inlet end b of the spout, as indicated by the arrows. By thus conducting the water through sand-boxes and having it enter the penstock near the rear of the penstock, the sand and other hea vy substances are deposited inthe boxes instead of accumulating Linder the spout. The spout D is placed centrally within its penstook,with its mouth in an opening, G, in the cross-wall E, to which the spout is pivoted upon the pins d', and it is loosely secured to the cross-wall by the flexible web F, which forms a water-tightconnection with the wall and prevents the passage of any water out of the penstock exceptthrough the spout. The spout is larger at its discharge end a than at its inlet end b, and the inlet end is further reduced by an offset at c, for the purpose of forming an air-space above the water to prevent suction and allow space for the smooth fiow of the water. The inlet endb is provided with a series of gates, d, made of different sizes, one ot' which is shown, to gage the quantity of water iowing through the spout, as required. The bottom of the inlet end b of the spout is provided with a downward step, j', which causes a fall and prevents a suction as the water enters the spout.

H H are floats formed of water-tight boxes of any suitable material, one being placed on either side and connected with the spout near its inlet end by means of a transverse bar, I,

each end of which has an axial connection with a bearing, c', on the top of a float, H, to allow it a rocking motion. A hand-screw, J, passes through a threaded aperture in the bar at its center, and at its lower end has a swivel connection with the spout, and by turning the screw the spout may be raised or lowered in relation to the position of the floats, and thus the depth and pressure of water iu the spout is regulated, it being evident that the greater the depth of the water the greater will be the weight aud pressure andthe greater the quantity of the ow of the water through the spout, and vice versa.

K is a spring, of any suitable material and construction, attached at one end to the spout D and at the other end to the casing, for the purpose of retarding the depression of the spout in case of rapid lowering of the water in the penstock. For example, where several boxes are used in the same ditch, if the spouts were not provided with the retarding-springs,

in case of a fall of water in the ditch the first spout would fall the full space of the fall of the wat-er, and each of the other spouts would receive a less quantity of water, the second less than the lirst, and the third less than the second; but by providing each spout with a retarding-spring having the requisite force, the depression of the spouts may be regulated IOO so as to secure through each an @quai lowof Water.

Having described my invention I claiml. In a water-distributor, the combination, With the penstock A and the automaticallyadjustable discharge-spout D, having its inlet end near the front of the penstook, of the sandboXes C C, provided With the inlet-gates B B at the front, and the exit-openings b b Within and near 'the rear of the penstock, substantially as and for the purposes described.

2. In a Water-distributer, the combination of the p'enstock A, the sand-boxes C C, provided with the inlet-gates B B at the front, and the exit-openings b b Within and near the rear of the penstock, the automatically-adjustable disohargespout D, having itsinlet end near the front of the penstoek, and provided with a gage-gate, d, substantially as and for the purposes described.
