The invention to be hereinafter disclosed relates to shower chines. J

Shower pipes of this general class are used for spray-washing in continually showering the rapidly moving making-wires, felts and various other parts of the paper making machines to keep them free from adhering fibres and foreign substances contained in the pulp. For economical andefiiclent cleansm of I I I I I b paper making machlnery t is essentlal to shower the parts to be cleansed with an unbroken and forcefulsheet of'liquid. The

most universally used and recognized type r such shower pipes is disclosed inthe Millspau'gh shower pipe Patents 7 82,680 and 7 82,7 55,both granted February 14, 1905, togetherwith his earlier Patents 596,939,

596,940 and 596,941, granted January 4, 1898, which latter three have been considerably dis- 1 placed bythe two first mentioned In each of these examples a continuous sheet of the cleansing liquid is obtained by a discharge pipe having'a line of orifices and provided with sultahle nozzles, deflecting lips or planes angulary disposed to the-actions of theis' suing jets or streams which infringe on said lips or planes andjthence discharge inthin sheets having diverglng sldes, the outer edges of which sheets all meet at the same line to form a continuous, unbroken sheet.

- struction, operation, and use of the invention,

The sizes and distances betweenthe O-I'ifiCP-s or dischargeiports and their positions relative to their deflecting planes determine the line at which the several streams meet, and the shower'pipe is preferably so located with relation to the parts to'be cleansed as to cause such meeting-line to lie on or approximately were made with rigid, fixed, or stationary defiectors. But, in the mills of the present time a considerably higher water pressure is used than in the earlier years of these later Millspaugh patents. The result is that in localities where there is any foreign matter in the There were objections to ed wit water the deflecting plate becomes grooved at pipes for paper makingma- V forations first strike. As soon as a groove starts, the otherwise fanshaped sheet formed by that particular jet correspondingly narpointswhere the jets issuing from the percorresponding strips or bands'of the wire or felt, leaving intervening unwashed bands;

The main object of the present invention is to avoid this serious defect and provlde a light, strong, erliclent and economical shower pipe in which the deflector plate may readily and easily'be adjusted to compensate for the grooving tendency, or easily and quickly completely be removed for renewal, when that becomes necessary. 7

To this end my invention consists, broadly of a shower-pipe having a longitudinal line of discharge-ports and closely adjacent thereto a deflecting plate or lip formed separately therefrom but longitudinally, slidably, keyed thereto in position to intercept and deflect in a single continuous sheet the several separate j etsissuing through the discharge-ports.

In order to more clearly disclose the conreferenceshould be had to the accompanying drawings. forming partof the present application. Throughout the several figures of the drawings like reference characters indicate the same parts in the several views.

In the drawings:

Fig. '1 isa side elevation of a pipe with the invention applied; 1 "Fig.2 is an enlarged crosssection at right angles to the-longitudinal axis and a slight'modification, V Referring to the drawings in detail,

.F 3 is a view similar to Fig.2," showing I i 1 indicates-the body of the pipe suitably mounted in well known manner and providh any desired connection to aisupply of water under pressure. This pipe is-drawn or otherwise worked to provide alongitudinally andhavinga snug fit therewith is the deflector plate 4 having the dove-tail channel or .groove 5 complementary to and receiving said rib. The metal of the channel piece has-a slight degree of spring or yield as shown at 6. Thus should :the :fit be tighter than desirable the zplate-will spread, slightlyandprevent bind-' wing. Likewise,*the-edges of the channel portions of the plate do not both fit snugly and iti 'htlyinto ftheopposite angles of the rib or tongue. If one edge makes a snug fit the other is slightly loose, .as clearly shown. Prefer- -ably, the one along the side opposite the perforations is the looser one. Should the other zone be the looser, water might work back from the perforations andbetween the rib and plate andcause rust or deposit and binding. It would also break the spray and destroy the continuity. of the sheet at this point. It will be noticed that. the dove-tail :tongue and groove as formed in this "case, has no "sharp angles. Wherever there would be a sharp angle there. is, instead, a gradual curve or rounded surface to, as n arly as practicable, entirely eliminate all binding at such points. i V V The operative part of the deflector plate is so inclined, positioned and directed with respect to the jet openings as to intercept the jets, spread them into one continuous sheet, and when the spraypipe is properly mounted :in'its machine, deliver that sheet against the wire felt or other part, at the point desired.

lVhile the sliding-fit between plate l and rib 2 is not'loose neither is it tight. Itis a snug fit and the plate may be moved longitudinallyyin either direction, by a moderate tap-on one ortheother end. Thus when any evidence of'groovi'ng appears it is only necessary :towtaptheplate end until it'is moved a distance equal to the diameter'of one of the perforations, or very slightly more, thereby ibringing into'operation'an entirely fresh and unused plate surface forevery jet. When all parts of the plate have been used or, for any other reason a new plate is desired, itmay be gsimplydrawlnoff and anewione substituted.

Obviously, plates of different inclination or design or otherwise different may be'similarly substituted when desired.

Preferably, the rib 2 is die-lormed'by reducing the diameter-of the tube or pipe. To more "readily get the dove-tail form -a. rod 7 maybe used, being held in thefol'd of the tube and thereby forcing the same into the fan or dove-tail form. This modification is clearly shown in Fig. 3.

It is thought that the construction, operation and use of the invention will be clear from the preceding detailed description wherein only a preferred form has been dis closed by way of illustration.
