wwf/W WW/KN Patented Dec. 3, 1929 UNITED sTATEs PATENT oFFlcE CHARLES B. REYNOLDS, F LA HABRA, CALIFORNIA JET-NOZZLE APPARATUS A Substitute for abandoned application Serial No. 719,008, led June 9, 1924. This application filed September 28, 1928.

This invention is a pump jet nozzle apparatus and consists ofthe novel features herein shown, described and claimed, and this application is a substitute for my applicatlon Serial Number 719,006, filed June 9, 1924,

and abandoned.

An object is to make a nozzle apparatus having a straight smooth central flow opening and havin an annular inclined slot or orifice for disc arging apower medium into the flow opening, there being an annular chamber from which the slot leads, and means for conducting the power medium to the chamber.

Another object is to make a power nozzle apparatus which ma be used for pumping li uid out of sumpy lioles and the like, and which may be used'for mixing two fluids together and for various other purposes.

Another object is to make a nozzle having a smooth flow opening for driven material and an annular angular orifice for discharging driving material into the driven material so as to move the driven material through the flow o ening.

Other o jects and advantages will appear from the specification and drawings.

The drawin s illustrate a pump jet nozzle apparatus emgodying the principles of my invention and showing the apparatus set up in various ways-for various purposes.

Figure 1 is a sectional elevation of a pit and a sectional elevation of the pump jet nozzle apparatus set up to empty-the pit of water, oil or the like.

Fig. 2 is a view analogous to Fig. 1 and showing a modification of the construction of the pump jet nozzle.

Fig. 3 is a view analogous to Figs. 1 and 2 and showing the nozzle set up with the intake at the top.

Fig. 4 is a fragmentary sectional detail showing the nozzle set up horizontally.

Fig. 5 is a sectional detail showing a second modified form of the nozzle.

The details of construction and operation shown in the drawings are as follows:

Referring to Fig. 1, the main frame of the nozzle consists of a lower casting 1 and an upper casting 2 having internally screw Serial N0. 308,536.

threaded nipples 3 and 4 in a straight line. The

castings

1 and 2 are finished upon their meeting faces and are connected together by flanges 5 and 6 and bolts 7 inserted through the flanges. In order to break the joint between the meeting faces of the castings a flange 8 extends 4from the casting 1 into a seat in the casting 2. A bell-shaped intake member 9 is screwed into the ni ple 3 so as to produce a flaring mouth 10 an a straight passage 11 in line with a straight passage 12 in the casting 1. The lower nozzle member 13 is seated downwardly into the casting 1 and has a straight central passage 14 in line with the

passages

11 and 12 and has a beveled outer face 15 leading to the upper end of the passage 14. An annular chamber 16 is formed in the casting 1 around the nozzle member 13. An upper nozzle member 17 is seated in the lower face of the casting 2 and held in place by screws 18 and has a passage 19 in line with the

passages

11, 12 and 14 and in line with the passage 20 through the casting 2.

The lower corner of the second nozzle member 17 is beveled to form a face 21 at the 0pposite side of the annular slot or orifice 22 from the face 15. The bevels of the faces 15 and 21 are divergent from the outlet end of the slot 22 downwardly toward the chamber 16 so that the slot 22 will be wider at its inlet than at its outlet. An elbow 23 is screwed into the nipple 4 and has a passage 24 in line with the

passages

11, 12, 14, 19 and 2O and a discharge pipe 25 is screwed into the elbow 23 and has a passage 26 communicating with the passa e 24.

It is o special importance that the

passages

11, 12, 14, 19, 20, 24 and 26 be all of the same size so as to make a smooth passage havf ing no protuberances or pockets to catch material moving through the passages.

An internally screw threaded nipple 27 is formed integral with the casting 2 and has a assage 28 leading downwardly to the chamer 16. A pipe 29 which may be of any desired height is screwed into the nipple 27, an elbow 30 is screwed upon the pipe 29, and the pipe 31 is screwed into the elbow 30, there be- 1ng a gate valve 32 incorporated into the pipe 31 and operated by hand lever 33 having a pawl 34 to engage a sector 35. A retractile coil spring 36 connects the lever 33 to the pipe 31, the tension of the spring being exerted to hold the gate valve closed.

The pump jet nozzle apparatus thus constructed is mounted in a pit 37 which may be a sump hole, a cellar, a basin, or the like, and the pit 37 may be filled Awith water, oil and water, mud, slush, or the like, which will readily iiow through the outlet passage from the. intake 9.

An desired uidpower such as water or the e, may be supp ied to the pi 31 under a desired power or pressure an when the lever 33 is operated to open the valve 32 a power medium will pass through `the slot 22 and force the liquid of the pit upwardly and outwardlythrou h the dischargepipe 25. The an le of disc arge of the nozz e 22 relative to t e flow opemng may be varied considerably. As shown in the drawings, the face 21 is at an angle of 45 relative to the axis of the flow opening considering the

passages

11, 12, 14, 19, 20, 24 and so on, and this angle may be greater or less to suit the conditions under which the nozzle is to be used, the only requirement being that the angle shall discharge the power medium in the same general direction as the direction of llow.

It will be seen from Fig. 1 that the fluid supply pipe 31 is at a higher elevation than the situatlon of the nozzle and the discharge pipe 25 and through the medium of the controlling valve in t e pipe 31 a means is rovided for controlling the flowing of a uid under a. pressure much higher than the hydrostatic head of the liquid to be pum d at the position of the nozzle. This deve ops a jet of high veloci through the nozzle and elevates the water m the pit 37. The pipe 29 ma be of any suitable length to give suicient eight to eifect the desired hydraulic head or if necessary suicient pressure may be given by direct pumpn Referring to Athe modi cation shown in Fig. 2, the

castings

38 and 39 are finished to formthe power medium outlet slot 40 and the castings are connected by

flanges

41 and 42 and bolts 43. Pipe coupling .

flanges

44 and 45 are formed integral with the

castings

38 and 39 and the pipe flange 46 is bolted to the

flanges

44 and 45.

AThe pipe line 47 is ta ped horizontally into the pipe flange 46 an the valve 48mg trols the ilow of power medium through the pipe line 47. The bellsha d intake member 49 is screwed upon a nipp e projecting from the casting 38 and the elbow 50 is screwed upon a mpple projecting from the casting 39, the parts being all arranged and finishedto make a strai ht smooth liow opening 5 1.

Referrin to ig'. 3, the construction 1s substantially t evsame as shown in Fig. 2, except that the nozzle is setbottom upward so that the intake member 49 is at the top and the outlet pipe includes a pipe 52 connected to the nozzle, an elbow 53 connected to the discharge end of the pipe 52, a pipe 54 connected to the elbow 53, an elbow 55 connected to the pipe 54, and a pipe 56 connectedto the elbow 55, as is necessary to get out of the secondary pit 57. The upper face 58 may be the normal bottom ofthe pit and the secondary pit 57 is dug below the level of the bottom 58 simply as a place to put the pump jet nozzle apparatus. In operation this apparatus will discharge all of theliquid above the intake end of the nozzle.

This apparatus might be set in a sump hole containing oil and water for the' purpose of skimming the oil off of the water.

Referring to Fig. 4, the nozzle 59 nny be igs.

the same construction as that shown in 2 and 3, the essential difference being that the nozzle is set to have the ilow openin 60 horizontal with the intake member 61 and the discharge pipe 62 in a straight line.

This construction might be used as a gas burner or oil burner, in which case the power medium would be steam or compressed air or gas, and it may be used for various otherpurposes such as washing a pipe or hose as it is passed through the opening 60.

Referrin to the modied form of nozzle shown in Fig. 5, the internall screw threaded pipe nipple 63 is formed7 inte al with the lower casting 64 which has a aring integral intake. formed upon the cting 64 and a rim 66 is formed the casting 67 to screw upon ngen 'the threads y5. The

members

68 and 69 forming the power medium discharge slot 70 are made sellarate and applied to the cast` so that t ey may be removed and chan as when the become worn or when it is desired to m e the slot 70 larger or smaller by using thinner or

thicker members

68 and 69. The width of the slot 70 may be adjusted to some extent by screwing the casting 67 up or down relative to the casting 64.

Thus I have produced a pump jet nozzle apparatus having a smooth ow opening for driven material and an annular angular oriiice around the iow opening for discharging driving material into the driven material so as to move the driven material through the flow opening.

Various changes may be made without departing from the spirit of the invention as claimed.

I claim:

1. A jet nozzle for elevatin a liquid comprising in combination a'liquid intake pipe, an annular nozzle to conduct another liuid into. said intake pipe, said nozzle comprising an annular chamber having two parts, an annular inclined jet opening having an .annular openin without obstructions leading into the in e pipe from said chamber, a

An external thread 65 is lli screw threaded connection between the two parts of the chamber whereb the nozzle faces ma be adjusted towards andy from each other, an having removable and replaceable faces for the jet opening.

2. A Jetnozzle for elevating a fluid comprising a pipe having a ange thereon, external threads on the flange, an annular recess between the exterior of the ipe and the flange, an inclined edge from t e recess to the interior of the pipe, a complementary pipe having a flange, an internal thread on the flange to enga e the first mentioned thread, a recess insie the flan e, an inclined annular edge leadin from t e recess into the pipe, the whole orming in combination an annular jet leading from an exterior channel formed by the complementary recesses and complementary inclined faces, and an aperture for leading a fluid into the channel..
