SHOWER-PIPE.

SPECIFICATION forming part of Letters Patent No. 782,680, dated February 14, 1905.

Application tiled May 2S, 1904. Serial No. 210,240.

Be it known that I` ELLIAM HULST-3 Mums- PAUGH, a citizen of the United States, residing at Sandusky, in the county of Sandusky 5 and State of Ohio, have invented certain new and useful Improvements in Shower-Pipes; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as will enable others skilled in the IO art to which it appertains to make and use the same.

This invention relates to that class of' perforated pipes or tubes known as "showerpipes, adapted for discharging water in sheet I5 forIn--such` for example. as the perforated pipes used in cleansing apparatus for paper- Inaking machines for showering` or washing the rapidly-moving making-wires and felt conveyers, also the dandy-rolls, cylinders, and

other parts of such machines to keep them free from adhering fibers and foreign substances contained in the pulp.

For economical and efiicient cleansing of paper-making machinery it is essential to 5 shower the parts to be cleansed with an unbroken and forceful sheet of liquid. Several forms of shower-pipes for this purpose are illustrated and described in my former United States patents, Nos. 596,939, 596,940, and

3O 596,941, issued January -L 1901. In each of these examples a continuous sheetl of the cleansing liquid is obtained by a dischargepipe having a line of orifices and provided with suitable nozzles, defiecting lips or planes angularly disposed to the action of the issuing` jets or .streams which impinge on said lips or planes and thence discharge in thin sheets having diverging sides, the outer edges of which sheets all meet at the .same line to form a continuous unbroken sheet. The sizes and distances between the orifices or dischargeports and their positions relative to their defIecting-planes determine the line at which the several st-reams meet, and the showerpipe is preferably so located with relation to the parts t-o be cleansed as to cause such meeting-line to lie on or approximately on the surface to be showered. The deecting lips or pla-nos are secured to the pipe adjustably;

but in practice it has been demonstrated that virtue of a closer arrangement of orilices and reduction of their sizes with a fixed deflecting pla-te or plates for uniting the discharging streams in a thin unbroken sheet at a short distance from the pipe.

'Io this end my invention consists, broadly, of a shower-pipo havingalongitudinal line of discharge-ports and closely adjacent thereto a deflecting plate or lip formed integrally with the pipe and projecting bodily therefrom at an angle to the ports or a number of such lips arranged parallel and constituting, in effect, a single continuous deliecting-plane, and, furthenthe improved construction hereinafter described and claimed of a seamless flanged pipe formed from a :split tubular piece 0f metal having its longitudinal edges flanged, drawn together, and bent over in proper relation to the line of orifices to provide the defiecting plate or plates.

The invention will be fully described with reference to the accompanying drawings, which are to be taken a part of this specilication, and then pointed out in the claims following this description.

In said drawings, wherein corresponding parts in the diiferent views are indica-ted by the saine symbols of reference, Figure 1 represents in longitudinal elevation or bottom plan View a section of' a shower-pipe embodying my invention, showing also the shower discharging therefrom. Fig. Z is an enlarged cross-section through said pipe. Fig. 3 is a cross-section showing the defiecting plate or flange before it has been bent over at an angle t-.o the discharge-ports. Fig. 4 is a longitudinal elevation of a fragment of the pipe. Fig.

discharge-tnl e, which may he mounted in a defiecting plate or lip 3, formed as an integral flange projecting bodily from the plpe jets or and discharge in sheets having divergent edges. which meet at a line near the pipe in one thin continuous sheet. In this instance the ports are formed radially and the deflecting-plate projects from the pipe at an angle to a plane transverse to its periphery. rl`his construction is simple and inexpensive, light in weight, strong, and durable. The integral flange or plate serves as a strengthening-rib and is not liable to become dislocated in the slightest degree, but always remains in fixed relation to the ports. Furthermore, a very close arrangement of the discharge-ports is permitted. By virtue of such close spacing of the orifices the issuing streams or divergent sheets are caused to blend into a. continuous sheet at. a. line much closer to the pipe, and hence the pipe can be set nearer the surface or part to be cleansed, which is not onl)- desirable from the standpoint of utility of space. especially in paper-making machinery, enabling a pipe to be placed where otherwise it. might be impracticable, but also causes the water to strike with greater force and with less loss of energy by friction with the air. By spacing' the orifices more closely their sizes may also be correspondingly reduc-ed, and thus a saving of water effected and a more even as well economical distribution of a given quantity of liquid obtained. The defiectingplane being continuous along the line of orifices insures an accurate alinement of the several discharging streams or sheets, so that they meet in the same plane and form a perfect unbroken sheet.

1t is feasible to sei-rate or cut away such portions of' the defiecting-plate between the orifices as are not traversed by the issuing jets or otherwise form a series of parallel deflecting-lips constituting, in effect` a continuous plane, and such variations which may be desired for reducing weight or other purposes will therefore be considered within the scope of my invention. A deflecting-plate so serrated is shown in Fig.

I shall now describe a novel and preferred mode of forming the pipe, which is facile and inexpensive and results in a construction of great simplicity, strength, and efciency. In Fig. 3 is shown a seamless tube having' a flange or lip drawn on same, as shown. This tube may be. formed from a strip of sheet or plate ingl its edges fianged outward, as shown. The

said flanged edges are drawn together and proper relation tothe part or surface to he 5 cleansed and havesuifable communication with a source of afer-supply under pressi'ne. The j pipe is perforated by a line of orifices or dis- Q charge-ports 2, and closely adjacent to and extending longitudinally of the line of ports is welded, brazed, or otherwise suitably joined to form the fiange or lip of thc finished tube. The discharge ports or orifices are then formed in the tube beside the flange, the orifices being usually formed radially, since this has been found mostsatisfactory, and the flange is then lnent over the row of orifices at the proper angle, resulting in the finished shower-pipe. at an angle to the port-s so that the issuing I "treams impinge on the defiect1n; ;'-plate i (Shown in Fig. 2.) Other modes may be followed in construct-ing the pipe, as by flanging one edge only of a strip rolled or formed into a seamless tube or by casting, rolling, or forming a tube in any of the usual ways with a projectingflange. lt may be desirable in some cases to weld or braze the deflectingplate on the tube, forming practically an integral structure, and this is also to be comprehended Within the scope of the annexed claims. It may also be desirable to provide a plurality of rows of orifices with defiectingplates for each row.

ln my copending application for patent filed May 14, 1904, Serial No. 157.162-, I have set forth and claimed an improved.shower-pipe having' a line of discharge-orifices and a fixed or rigid deflecting-plate extending longitudinally of and continuous with said line of orifices and projecting from the pipe at an angle thereto. As one embodiment of the invention claimed in said application there is illustrated a pipe having an integral flange or deflecting-plate, to which, however, no specific claim per se is made therein.

I claim as my invention and desire to secure by Letters Patent of the United Statesl.
