SHOWER PIPE FOR SUCTION ROLLS Filed.ApIil 14, 1934 3 Sheets-Shes?l 2 "un n l fil lllI/lllllllllllrllllllllllln. i

Patented Oct. 30, 1934 PATENT lOFfTFlIfClE STATES .This Ainvention relates to 4suction rolls, and more particularly to `an arrangement of the shower pipes of rsuction rolls.

Suction rolls are substantially universally proalfvided Withishower `pipes Adirecting sprays of liuid 4against the inner surface of the shell immediv`atelyrin advance of that edge of the vsuction box `,first 'engaged by agiven portion of the shell in 'Sits rotation. lParticles of nbre vand felt passing "d through the openings of the shell collect upon the pipe 'tending to clog the `openings and, fur- "therr'norapar'ticles of foreign matterin the water delivered through the pipe vgather inthe openlings' and tend to clog the same so that the shower {3,3'15 pipeifhas ltolbe removed Vand cleaned. This must Abe `done whenever the shower fails to operate properly, for this lshower in addition to cleansing the roll lubricates'the inner surface of the roll '-so -that it may not have too great a frictional jzo engagement with the packings of the suction box. As at present c'zonstructed,l such devices require* dismantling of -the roll in order that they "may fbe removed for cleaning, and an important 'object of the present 'invention is the provision w25 of 'a shower pipe varrangement permitting the .pipe to be removed for cleaning without dismantling the roll.

A further object 'of the inventionis the provision inra device of `this character iof anarrangement such that the shower pipe can Abe `removed without breakingany actual `pipe connections and simply disengaging the shower pipe from a rslip joint through which its connection with the water supply is provided. n.35 f A further object lof the invention is the provision of'a shower pipe so constructed that it Amay be veri7 readily cleaned andfmay be readily inserted 'into position in the roll. These and other objects I attain by the conist`ruction shown in the `drawings wherein, for

lthe purpose of illustration Ih'ave shown a preferred embodiment of my invention and wherein: Fig. `1 is a longitudinal sectional View through a 'suctionroll equipped With a spray pipe in ac- Acordance with my invention;

2 fis an end elevation of the Asuction roll; `liig. f3 is a transverse sectional view therethrough; i -Fig-L 4 is a ViewV of the suction box removed @showing the'method of mounting the spray pipe thereon; Figp is an enlarged sectional View showing 'the spray pipe in position in a supply head;

, Fig. 6 is a View showing the spray pipe removed;

55 and Fig. 7 `is adetail sectional view Villustrating the method of conducting uid to the supply head.

.Referring now more -particularlyto the drawings, the numeral 10 generally designatesa `ro- 60 tating shell of a suction roll; 11, end v'heads therefor, having hollow trunnions 12 mounted in suitable bearings 13, one of 4theseend heads being `connected `as usual to the drive mechanism indicated at 14 through its trunnion. Within the 65 shell isarranged the -suction -box 15, thisbox being at `present shown as of that -type illustrated in the prior patent vto -EdwardT. `Street under date of June 30, 1931, No. 1,812,812, for

`Suction rolls. The ends of this suction box lhave trunnions 16 and 17 which are mounted and guided in the trunnions 12 of the shell,

In accordance With my invention, the trunnion Y17, which is projected entirely through the associated shell trunnion `in order that it may be connected with adjusting means generally designated at 18, has arranged therein a longitudi- -a substantially tangentially-extending vconduit 20 the upper end of which is equipped with 85 a tting more particularly shown in Fig. 5. This fitting comprises a tubular chamber 21 the bore of which is tapered adjacent one end as indicated at 22. The side wall of the chamber has an opening therethrough at such tapered portion as indicated at 23 for communication with the conduit 20. The opposite end of the chamber 21 is threaded, or otherwise adapted at 24, for convenient attachment of a head 25. InWardly of this connection, a slot 26 is formed in the 95 inner surface of the chamber for a purpose presently to appear.

The axial bore of the chamber 21 is `directed. along one side of the suction box; i. e., that side thereof bearing the packing 27 which is rst en- 100 gaged by any given portion of the shell l0 during its rotation. Secured to the suction box are a plurality of brackets 28 each having an opening 29 coaxial with the bore of chamber 21. The spray tubecomprises a tubular body 30 `enclosed 105 at its opposite ends as indicated at 31 and 32, the closure 32 comprising a plug secured to the tube by a pin 33 which projects beyond the outer surface of the tube and engages in the slot 26 of chamber 21 in order that the openings of the tube l `lil 'zie may be properly directed. The closure 31 comprises a tapered plug threaded into the end of the tube and apertured at 34 to permit the insertion of a tool whereby this closure may be removed. Pin 33 may have a loose fit so that closure 32 may be readily removed through medium of a handhold 35 connected therewith, which handhold ernbodies a portion rotatable in the head and has threaded engagement With the closure 32. The exterior surface of the tube, adjacent closure 32, has sweated or otherwise secured thereto or pro, vided thereon a tapered conical surface 36 adapted to fit the tapered bore of the chamber and through the tube and this tapered vsurface an opening 37 is formed which aligns With the opening 23 ofthe chamber when. the tube is in position therein.y

Since the handhold is rotatably engaged by the head 25, it will be obvious that this Vhead'may be rotated to disengage it from the chamber, the head being provided with angular shoulders 38 'for engagement by a Wrench. The head, during rotation to disengage .the same `from the chamber 21, engages a shoulder 35a on handhold 35, breaking the taper joint connection so that by anaxial pull` the unit constituting the spray pipe may be Withdrawn from the chamber. The adjacent -head 11 of the shell has an opening 39 formed 'therein which may be aligned with the tube and 'through which the tube may be withdrawn and reinserted, and the head 25 is readily accessible ythrough such opening for disengagement by means of asocket Wrench. When the tube is Withdrawn, the closures of the opposite ends thereof may be In reinserting the tube, the closure 3l assists in engaging the tube in the openings -of the brackets.

Since the arrangement herein described is, obviously, but one of a number of similar constructions lvvhich will be suggested thereby, I do not Wish to rbe understood as limiting myself to such construction except as hereinafter claimed.
