WILLIAM D. BARBER, OF CHCAGO, ILLINOIS.

SUBMERGED CREE AND INTAKE.

Application filed December 29, 1913.

To all I207mm t may concer/a Be it known that l, VILLIAM D. BARBER, a. citizen of the United States, and a resident of Chicago, county of Cook, and State of illinois, have invented a certain new and useful Improvement in Submerged Cribs and Intakes, of which the following is a description, reference being had to the ac companying drawings, which form a part of my specification.

My invention relates to a water intake and crib for use in connection with a municipal water supply; the crib beino' adapted to be built or set and submerged in the body of water, from which the supply is had, at a suitable distance from the shore line, and the water is delivered from the crib and intake to the pumping station or stations, on shore, through the action of gravity.

@ne object of myv invention is to provide a. crib having a number of inlets or pipes which are also intended to be submerged and extended to a considerable distance from the crib so as to increase the area of supply and at the same time also reduce the suction effect that ias heretofore been encountered at the intake port of a crib as previously constructed.

TVith my improved construction, the in take shaft, which leads to the shore or the pumping stations, has direct communication with the chamber or well with which the 'various inlet conduits or pipes communicate. This construction eliminates the difliculties encountered with the intake construction as heretofore employed, (wherein the intake was formed to provide an extension rising into the well of the crib, which also necessitated the employment of suitable sluice gates) as such construction would permit foreign matter to drop into the well or intake shaft when the gates and screens were being repaired, etc. lWith my improved construction, the necessity for sluice gates is obviated, so that the construction is ma terially simplified as will be readily apparent from-.the following detailed description.

A further object of the invention is the provision of inlet conduits or pipes so arranged that the water is prevented from passing directly into the intake ends of the pipes or conduits, and is compelled to flow from a point beneath the orifices of the various intake conduits by reason of the Pmftculal COHSWC-On hereinafter to be d@- Speccaton of Letters Patent.

Patented Dec. 2o', igt@ serial No. 809,394.

scribed; the construction of the inlets is such that it will prevent any suction elfect being induced which would cause surface water to flow into the inlet pipes or conduits. By reason of my improved construction, the water will be drawn in a gradual manner from points near the bottom of the lakeor other body of water, so that the difficulties which have heretofore been encountered through sudden changes in velocity, direction of flow, cross currents, etc., will be entirely eliminated; furthermore, the possibility of having the inlets or ports obstructed by ice, etc., will not be encountered.

A rcther object of my invention is the provision of a construction wherein the respective inlets or conduits may be independently cleaned or repaired without affecting the genera-l operation of the crib and intake, as the improved construction permits of a complete closure of the different inlets or conduits being made 'for the purpose of repair, etc., without the necessity, however, of employing any complicated mechanism for opening and closing the various inlets.

The advantages above recited, as well as other advantages inherent in the construction, will be readily apparent from the following detailed description.

In the drawings :-Figure `l is a partial plan and partial sectional view of my improved submerged crib and intake, with the inlet pipes or conduits shown broken away, and a plan view of but one of the hooded ends of the inlet pipes or conduits being shown. Fig. 2 is a vertical sectional view taken on the line a-a of Fig. l, looking in the direction of the arrows. Fig. 3 is a partial plan view and partial horizontal sectional view of the hooded end of an inlet pipe or conduit. Fig. it is a vertical sectional view taken on the line 7)#2) of Fig. 3, with the conduit or pipe shown in full lines and broken away. Fig. 5 is a detail sectional view of the end of an inlet pipe or conduit adjacent the walls of the crib or well, illustrating the method of forming connection with the ports of the crib 0r well. Fig. 6 is a similar view illustrating the method of closing the inlet port through the removal of the connection shown in Fig. 5. Fig. 7 is a diagrammatic view of my improved construction illustrating the general arrangement, with the inlet pipes or conduits and the intake shaft shown in dotted lines. Fig. 8 is a diagrammatic view show? ing the general arrangement in elevation, with portions of the construction broken away.

As an eXempliiication of my invention, I preferably illustrate asubmerged crib and intake of circular contour, wherein the wall is composed of concentrically arranged metallic shells 10 and 11, spaced apart so as to t receive a filling of concrete as shown at 12,

see Fig. 2; the composite wall of concrete and metallic shells being formed to receive the ports or conduits 13, more clearly illustrated in Fig. 1. In order to increase the area of supply, I have shown the ports 13 bifurcated at their outer ends as very clearly shown in Fig. 1, so that each port or conduit 13 receives the water supply from two inlets or conduits 14, 14. This arrangement and construction is very clearly shown in Figs. 1 and 7.

The intake shaft 15 is shown with a vertically disposed portion 15a and the horizontal or laterally leading portion which conveys the water to shore or pumping station; and the upper end of the vertically disposed portion terminates in the flared end or well portion 16, located within the inner shell 10, as clearly shown in Fig. 2. The end 16 of the intake shaft is provided with a covering, which, in the particular construction shown in the.drawings, prefer- .ably consists of the two arched metallic plates or disks 17 and 18 spaced apart with concrete intervening. This covering is shown supported or secured at the sides by the flanges 19 and 20 respectively, which latter are shown` secured to the side of the inner metallic shell 10. Instead of forming the covering as shown, it may be madev of reinforced concrete. It is understood, of course, that the covering is so secured to the inner shell 10 as to prevent any possible displacement. In order that access may be had to the well 16, or the shaft, I show the covering provided with la suitable man-hole 18, closed by a cover 19a provided with means whereby it may be lifted from place when desired. The man-hole 18a may be made with sloping or off-set sides as clearly shown in Fig. 2, so as to permit of the proper seating of the cover 19a.

The outer ends of the bifurcated ports 13 are preferably madeto extend through the outer shell 11 where they are provided with flanges as indicated at 21, more clearly shown in Figs. 5 and 6; the anges being intended to receive suitable bolts 22 which also pass through flanges en the adjacent section 14L of the inlet conduits 14, thereby securing the section and member 13 together with the intervening joint forming members 23 and 24. The joint forming members 23 and 24 are in the nature of ferrules or short sections of pipe oppositely beveled as very clearly shown in Fig. 5` whereby a Huid tight slip connection may be formed,

which will permit of a ready removal or disconnection being made through the loosening of the nuts on the bolts or connectl ing rods 22, as is very clearly apparent from 'the construction shown. If for any reason flange 21, by means of bolts 26; the cap or cover 25 fitting into the space intervening between the adjacent ends of section 14a and inlet conduit 13 provided by the rcmoval' of the joint forming members 23 and 24.

The outer ends or orifices of the inlet pipes or conduits 14 are preferably turned upwardly as clearly shown in Fig. 4, so as to extend somewhat above the bottom of the lake or body of water from which the supply is taken. The outer ends of the different inlet conduits 14 are provided with basins or shallow members composed of a cover 27 which is bolted to a grated bottom portion 28 as clearly shown in Fig. 4. The inlet end or orifice of conduit 14 is preferably embedded in a concrete foundation as indicated at 29 having an annular depression to conform with the outer contour of the bottom 28 of the hood member or basin. In the particular exemplification of this part of the invention, the hood or cover 27 is pro vided with a shedding surface and provided with an eye 30 whereby the hood or cover, or entire basin members, may be lifted by proper means secured thereto. The bottom of the basin or grated member lies in a plane beneaththe orifice of the inlet pipes 14, so that any matter that may pass through the grating will have a tendency to drop to the bottom of the basin. The basin is provided with a screen 31, of any suitable mesh, preferably at a point somewhat beneath the orifice of the inlet pipes, see Figs. 3 and 4. This screen 31 is preferably secured to the cover 27 by means of suitable bolts 32 and the depending brackets or rods 33. In the construction illustrated, the brackets or rods 33 are bolted to a pair of rings 34 and 35, placed on opposite sides of the screen 31, thus providing a proper clamping and support for the screen. The screen will prevent any foreign substance which may have entered the bottom of the basin from passing upwardly and into the orifices of the inlet pipes 14.

It is evident from the construction'that when the bolts 36, which secure the cover 27 to the bottom 28 of the basin, are removed, the cover 27 may be lifted upwardly thereby also lifting the screen 31 so that easy access to the interior of the basin may be had. In order that the cover or the basin, when either has been raised, may be properly centered, I show the cover 27 provided with a number of lugs 37 arranged in pairs, as very clearly seen in Fig. 3, adapted to extend to opposite sides of the posts 38, of which any sufiicient number may be employed; the posts 38 Will also more or less protect the basins and inlet ends of pipes 1i.

With the construction just described, it is evident that the inlet ends of the pipes or conduits lll Will be protected from any heavy material or foreign matter which may be dropped into the Water, as the hoods or covers 27 Will deflect the material to one side. Furthermore, the particular arrangement of the inlet ends Will prevent the suction effect previously referred to, because the Water is taken from a plane beneath the oriiices of the inlet pipes.

ln the construction of my improved intake, the metallic Walls 10 and 11 are provided with the desired number of openings to receive the conduits or ports 13, which are put into place with heir outer ends closed by suitable covers or caps as shown at in Fig. 6. The shells and conduits 13 are preferably assembled on shore, and the Walls 10 and 11 extended to a height Which is accomplished by securing a sufficient number of similar metallic sections together, so as to provide a pair of concentric shells of a height commensurate with the depth of the Water at the point Where the crib is to be located; the steel shells to constitute the Walls of the crib are then towed to place, namely at the inlet orifice of the intake-shaft 15. Before towing the united sections of the steel shells, it .vill be understood that the inner ends of the ports 13 are also preferably capped or closed in any suitable manner so that Water will be prevented from ovving thereinto, until it is desired to sink the shells. After the shells of the crib have been sunken into place, the Water intervening the shells is pumped out and the desired concrete filling shown at 12 may then be constructed about the respective conduits or ports 13. l/Vith the outer ends of the ports 13 still capped, the contents of the inner shell 10 are then pumped out in order that the Well 16, as Well as the orifice of the intake-shaft may be formed. The covering or roof, preferably composed of the disks or plates 17 and 18 and intervening concrete, or of suitable reinforced concrete, is then secured in place as shown in Fig. 2; it being understood, of course, that before the covering is put into place, the caps or plugs at the inner ends of the ports 13 are removed. rlhe Well and ports having been constructed, as just described, the connections With inlet pipes 14, which have previously been laid in the prearranged manner, are then formed by removing the caps 25, inserting the joint forming members 23 and 2st, and fastening rods or bolts 22 into place so that the joint forming niembers 23 and 2li will be securely clamped into position. it is evident that as soon as the inlet conduits are properly connected to their respective ports, Water will flow therethrough and into the flared mouth or Well 16 of intake-shaft 15. The construction of the crib and intake having been completed, the upper sections, (shown in dotted lines in Fig. 2) corresponding with and secured to shells 10 and 11, (which constitute a part of the crib Walls) are then disconnected and removed, thus providing a submerged crib, as indicated in F ig. S, that Will be free from the diificulties encountered by a surface crib as heretofore constructed.

l have illustrated both the crib and the inlet basins, at the outer ends of inlet pipes 14e, of circular contour, as the preferred form of construction; it is evident, however, that they may be given a different configuration; furthermore, the inlet ports need not necessarily be bifurcated at their outer ends as illustrated. l have also shown the inlet pipes 14, which connect With the same inlet port 13, extending to diderent distances from the intake-shaft, so as to greatly increase the area of supply and thereby also tend to reduce any suction effect.

lt is apparent that my improved construction is conducive to a purer Water supply than that obtainable with cribs and intakes as heretofore constructed. rlihe construction, hoivever, as previously stated, may be altered in certain respects Without, however, departing from the spirit of my invention, and l do not Wish to be understood, therefore, as limiting myself to the exact construction shoivn and described.
