HENRY GOYETTE FIG. 5 44 54 ATTORNEY IlitfiCi StatcsPatent Patented Aug. 16, 1960 DRIPLESS STEAM SHOWER PIPE Francis Henry Goyette, Worcester, Mass., assignor to Lodding Engineerings Corporation, Auburn, Mass., a corporation of Massachusetts Filed June 24, 1959, Ser.

7 9 Claims. (Cl. 239-120).
This invention relates to a new and improved dripless steam shower pipe particularly adapted for use in the paper-making industry and for the purpose of apply-.
ing moisture to a web evenly by means of a steam shower where the web may be traveling through a set of rolls for instance or on a Fourdrinier wire, or in any other relation. The principal object of the invention resides in the provision of an apparatus for applying the steam shower without spitting, whereby an even continuous moisture is provided on the surface of the paper without blobs or drops of moisture being ejected from the shower-head as has been the problem in the prior art with respect to the application of moisture to paper in the process of being manufactured, particularly in calendermg.
In the past it has been found that a steam shower directed against the paper web discharges drops of water, spitting, together with the steam condensation occurs in the steam shower-head, which condensation is frequently blown out along with the steam and applied to the paper in drops. This produces weak spots and imperfections in the final paper sheet, and in some cases causes the web to stick to the calender rolls, and also causes streaking in the finished paper.
It is the principal object of the present invention to provide an apparatus for providing the steam shower continuously, uninterruptedly, and without any drops being discharged from the steam shower to the paper. To this end, the invention comprises the provision of a new and improved shower-head which may be in the form of an elongated sheet metal chamber or the like extending from side-to-side of the web and in which there is provided a smaller pipe which leads live steam into the aforesaid chamber, together with ispecial new and improved means providing for catching of any condensation within the shower-head chamber and depositing the same at the bottom of the sheet metal chamber whereby the same may be quickly and easily discharged without coming in contact with or even approaching a special new and improved spout or steam orifice within the chamber; the provision of a device or apparatus as above described including a spout inside the main or primarychamber which directs the steam from the chamber outwardly thereof against the paper web, said spout being elongated and comprising walls which converge from the inner portion of the main or primary chamber toward the exterior thereof, and narrow down to a relatively small slit or elongated orifice through which the steam is expelled under pressure, said spout walls 'being unequal in length and having a relatively shorter wall located underneath an upper wall, whereby condensation running down the longer upper wall will fall into the main chamber and be discharged, rather than having any possibility of falling into the area of the spout where such condensation could Reference is to be had to the accompanying drawings, in which Fig. l is a view illustrating the apparatus and an application thereof to a set of calender rolls;
Fig. 2 is a section on line 2-2 of Fig. 1;
Fig. 3 is a view showing an enlargement of the barriers centrally located in the apparatus;
Fig. 4 is a section on line 44 of Fig. 2; and
Fig. 5 is a view in elevation, looking in the direction of arrow 5 in Fig. 4 and showing the orifice of the spout.
In carrying out the present invention, the same is shown as applied to a Web of paper 10 which is traveling through the nip of a pair of calender rolls 12 and 14. As shown, the steam shower-head or chamber which is the subject matter of the present invention is indicated generally by the reference numeral 16., chine and it is mounted in any way desired, as for. instance at its ends on the framework of the machine as indicated at 18 and 20, upon a pair of brackets or other supports 22, 24.
The present construction is preferably divided into two longitudinal sections which are co-axially arranged and are supported between the ends of the framework of the machine. This is for the reason that the steam may be applied to one-half only of the traveling web or it may be applied under different pressures to the two halves of the web. In any event, there are two steam inlet pipes indicated at 26 and 28, and these pipes lead steam under pressure from any source to a generally central location in the steam shower-head as indicated generally at 30, 32. The representation of 30 and 32 isin the form of an ordinary cylindrical pipe or pipes having steam orifices at 34, 36. It is preferred that these orifices point downwardly- The pipes are located generally centrally and axially of a sheet metal or the like chamber indicated at 38. As shown in Fig. 4, this chamber is provided with a semi-circular portion at the right side thereof, the pipe 32 being located generally in the center. The walls 40 and 42 extend from this portion and converge toward and form a pair of rounded lips 44 and 46. At the lips, the walls are curved re-entrantly into the interior of the showe-rhead chamber and these walls are indicated at 48. and 50. Walls 48 and 50 diverge toward the pipe 30, 32 as clearly shown in Fig. 4 and the converging walls 40 and 42 point upwardly to the left was to be arranged 5 to cause the steam shower to impinge upon the paper web was shown in Fig. 1.
' Wall 50 is shorter than wall 48, wall 50 being the lower wall of the spout, under wall 48, and these walls may be strengthened and held in position by means of separators or pins 52 and 54 and there are shown other pins .these communicating if desirable.
which connect the lips'of the the same. I a
At the bottom of the semi-circular portion of the chamber there is provided a pair of drains as at 56 and 58, Any moisture which condenses within the chamberSS will of course flow down spout and help to rigidity and out through these drains.
The chamber may be mounted if desired in a pair of journal- like members 60 and 62 and the rotative position thereof may be adjusted by means of these journals which are mounted in corresponding blocks 64 and 66.
. The-two pipes 30 and 32 are separated by means of a plug or block 68, see Fig. 3, and the steam chamber itself may be provided with a dividing partition 70, so that steam entering pipe 26 is distributed through the left-hand one-half part of the shower-head, and steam coming in through pipe 28 is distributed through the right-hand side thereof.
- In the operation of the device, the steam issues from ports 34 and 36 and under steam pressure it then issues through the spout formed by the converging walls 48 It extends across the ma- 7 3 and 50 and out through the nozzle at the lips 44 and 46. Any condensation of the steam in the chamber falls to the bottom thereof and out through the drains. If any condensation is formed at the under side of wall 50, it again falls down the incline to the drain whereas condensation formed against wall 40 will fall ontothe upper surface of wall 48, and off the end thereof as at 72 without, however, impinging upon wall 50. If moisture should collect on the top of wall 50, it might be blown out with the steam, but in this case no condensation will form at that point since there is a continuous passage of steam through the nozzle between the converging walls 48 and 50, and the only condensation is at the under surfaces of the main part of the chamber or on Walls 48 and 50, whence it will run off without damage.
