BLOWER NOZZLE ron TRANSPORT LINES.

' Application filed November is, 1926. Serial No. 149,076.

This invention relates to-blower nozzles for transport lines.

The transportation of fluent solids, such as powdered coal, flour, cement, sand, and the like, has been known for many years. Fluid pressure is frequently employed for this pur-- pose, particularly where the distance of transportation is considerable. This fluid pressure is supplied at a number of points in the line also depending on the distance of transportation.

The nozzle of my invention is generally ap- I plicable for the transportation of such and similar materials, and it is one of the pmmary objects of the invention to provide a simple, inexpensive, and effective fluid .pressure nozzle device which can be applied in such lines. I I I How the foregoing, together with such other objects and advantages as may hereinafter appear, or are incident tomy invention, are realized, is illustrated in preferred form in the accompanying drawing, wherein-.

The figure is alongitudinalsectional view of a nozzledevice constructed in accordance with my invention and associated with a transport line.

Referring to the drawing, it will be seen that the blower nozzle A, in general form, re-

sembles an ordinary pipe coupling, and, in fact, is applicable to'a pipe line as such. In

. this particular instance-, the nozzle A is associated with a fuel transport line B.

The blower nozzle A comprises a pair of flanged members 1 and 2 secured together, as by means of the bolts 3, which fit suitable apertures in the flanges of the members. The

' groove 8 in its face,the other with an annular members 1 and 2 areprovided with screw threaded portions 4 and 5 ,respectively, into which are screwed thesections 6 and 7 of the transport line Bf Thus, it will be apparent 'that these members of the nozzle serve as coupling members for the line.

One of theflanged members is provided with an annular substantially V-shaped upstanding substantially V- shaped rib' 9 on its face, the rib 9 projecting into the groove 8 when the'parts are assembled as shown. The relative size and disposition of the groove and the-rib are such that an annular chamber nular discharge nozzle 11 opens to discharge pressure fluid into the line in a hollow'conelike body, as indicatedin dotted lines. The

pressure fluid is supplied to the pressure chamber 10 by a pipe 12.

chamber 10 approximates the capacity of the fluid supply pipe 12, and that the capacity of the nozzle 11 is considerably less than the capacity of the chamber 10. By way of example, desirable conditions prevail when the capaeity 'of the chamber is 90% of the ca-- pacity of the supply pipe, and the capacity of the nozzle of the chamber.

It is further to be noted that there is absolutely no restriction in the line, the tapermg surface 13 of the member 2 terminating substantially in line with the inner surface 14 of the member 1, which inner surface is of a diameter equal to the inner diameter of the line B. Thus, the device itself does not add any obstruction in the line, obstructions being objectionable as involving increase in the power requirements. The nozzle is also effective to reduce resistance in the line, and,

. It is pointed out that the capacity of the therefore, decrease power requirements for localized at the surface of the wall.

It will be seen from the foregoing that the nozzle is an effective one, and that it is formed by a construction which is exceedingly simple, which construction merely involves two simple coupling members, each of which is adapted to serve as a means for coupling the sections of the 'line together. a I The flanges of the members 1 and 2 may be made of standard size and to suit pipe stand-- ards.

I claim 1+ 1. The combination with a transport line,

of a blower therefor comprising. a pair of coupling members, one having a rib and the other havin a. groove for receiving the rib, said rib and groove being of such size relative to one another as to provide a nozzle for directing fluid into the transport line, and

means for admit-ting fluid to the nozzle.

2. The combination with a transport line of a blower therefor comprising a pair of coupling members, one having an annular rib and the other havin an annular groove for receiving the rib sald rib and groove being of such size relatlve to one another as to provide an annular nozzle for directing fluid into coupling members, one having a substantially I V-shaped rib and the other having a substantially V-shaped groove for receiving the rib, said rib and groove being of such size relative to one another as to provide a nozzle for directing fluid into the transport line, and means for admitting fluid to the nozzle.

4. A blower nozzle comprising a pair of pipe flanges, one having a substantially V- shaped rib and the other having a substantially ii-shaped groove for receiving the rib,

said groove having a depth greater than the height of'said rib and said rib being more closely adjacent to one side of the groove than to the other side thereof, whereby a chamber and a nozzle are provided, and means for admitting fluid to said chamber for discharge through the nozzle.

5. A blower nozzle comprising a pair of pipe flanges, one having a substantially V- shaped rib adjacent the bore thereof, and the other having a substantially V shaped groove adjacent the bore thereof for receiving the rib, said rib and groove being of such relative size andso spaced as to provide a nozzle for directing fluid inwardly and longitudinally of the flanges, and means for admitting the fluid.

In testimony whereof I have hereunto signed in name.
