fgAPER-MAKING MACHINE.

Application led January 12, 1927. Serial No. 160,722.

This invention relates to certain improvements in steam heated rotary cylinders such as the dryer rolls for paper making machines, and particularly to improvements in the steam joints and the mechanism for supporting and adjusting the Siphon tube used with such dryers.

lVhile the invention as to certain of its features has been designed for and is uscful with various revolving hollow rolls or cylinders to which steam is supplied, or from which water needs to be extracted, the invention will be described as employed with the drying rolls or cylinders of paper Inaking machines, for which it has been particularly designed. I

Dryers for paper making machinescomprise large hollow cylinders over which the web passes from the making end of the machine. These cylinders are usually heated by steam and, where steamis used, means must be provided for supplying the steam and withdrawing the water'of condensation from the cylinders. This is usually ei'ected by some form of steam joint and a slphon tube or ipe which extends into the dryer. To be e ective, it is necessary that the suction end of this siphon be near the bottom of the cylinder, but, in order to avoid injury to the pipe, it is desirable that the suction end of the pipe shall not contact with or drag on the wall of the cylinder, for 1f the 'pipe is permitted to so drag it will wear so as to conform with the cylinder wall forming a seal, which thus destroys its function. s

It is the special object of the present 1nvention to provide an improved steam jointl and an improved construction for support- 4o ing the steam joint and determining the .po-

sition of the suction end of the Siphon pipe, so that the operator can tell b the pipe when it is in contact wlth the cylinder wall and can thenv adjust the pipe so that it will lie in the desired position close to but out of contact with the wall of the cylinder. l A further object of the invention is to provide such a construction in which this 5o adjustment of the ipe can be effected while thelmachine is eitlier running or standlng stil the feel of A further object of the invention is'to providean lmproved support for the pipe and an improved steam joint or steam connection which will relieve the pipe of load 4and the novel features pointed out in the claims hereunto annexed.

In these drawings,-

Figure 1 is a central side elevation, partly broken away, of the improved construction for supporting and adjusting the Siphon pipe and supporting the steam joint;

Figure 2 is a sectional broken away view showing the relation of the Siphon and the drying cylinder with which it is used;

Figure 3 is a detail sectional view taken on the line 3-3 of Fig. 1; 4

Figure 4 is a further detail sectional view taken on the line 4--4 of Fig. 1, and

Figure y5 is an enlarged sectional view of the adjusting mechanism shown in Fig. 1.

Referring now to thesedrawings, the improved siphon arrangement has been shown as employed with a drying cylinder 1, it being understood that the .construction will be used with all or as many of the drying cylinders of the machine 'as may be desired. As the constructionv is the same, but one drying cylinder has been illustrated. This drying cylinder is steam-tight,l being formed with heads 2, one of which is shown, which head is vformed with a journal?) by which the dryin cylinder is rotatably supported in any suita le framing, not shown. Secured to the end of the'journal and revolving with it is a packingbox and a. bearing of improved construction, whi'ch receive certain parts hereinafter referred to. This improved packing bo'x and bearing are arranged so as' to be steam-tight, and form a steam joint. While the particular construction of these may be somewhat varied, it will, as shown, comprise two partsa pack-h ing gland and a bearing independent of the gland.- As shown, this packing box and bearing are secured to the end of the journal ina? suitable manner, as by means of bolts 4. he packing gland includes a ilange ring4 `5 to which is secured, by bolts 6, a collar 7, packin 8 being rovided betweenthe collar and t e ring. eyond the ring, but' Secured thereto by a web 9, is a roller bearing comprising a casin 10 and rollers 11.

It will be seen with this construction that the bearing is entirel outside and independent of the packing g and, so that there is no access thereto of steam or water, which is a desirable feature. Furthermore, this bearing takes yall the load due to the weight of the parts or steam pressure, so that the only 4 from the dryin v that Iany .dragging function ofthe seal.

It will be understood that the parts so `far described rotate with the journal of the drying cylinder. Mounted so as to extend a suitable distance into the hollow journal 3 is a sleeve 12. This hollow sleeve passes through the packing gland, andrtherolle'r bearin revolves on this sleeve, which is se.- cured means of bolts 13 to a connection 14 whic has a steam chamber 15 connected with the steam inlet 16 and a Water chamber 17 connected with the water outlet i e 18. These chambers 15, 17 are divided) Ey a web 19, hereinafter referred to.

The water of condensation is removed clinder by meansv of a siphon pipe 20 w ic is supported at one end in a splder 21 in theinner end of the sleeve packing gland is that of a 412 and atits other end in. a bearing 22 secured to the connection 14, before referred to, packing 23 being provided in the bearing to seal the arts. This siphon tube, it will be observ curved downwardly so as tolie close to the inner surface of the cylinder.

In accordance with the invention, means are provided whereby the position of the ,suction-end 24 of this siphon pipe 20 may be accurately adjusted by the operator, and this mechanism will be such that the operator can make the necessary adjustments without having to look or get into the drying cylinder. These means may be somewhat varied. There will be provided, in the best constructions, means by whichthe pipe as a whole may be swung around the dryer so of the end of the pipe with the inner sur ce ofthe dryer shell may be readily felt by hand and the si hon then adjusted to brin the suction end t elesired distance from t e inner surface of the cylinder wall. f

As shown, the si hon pipe is formed at its outer end with a c osed headprovided with a projection 25 to which is secured, by a set' screw K26, a handle 27. This handle lmay be locked in position byineans of a stopv pin 28., which works in a Aprojection 29 formed on the handle and enters a recess, inj extends through the hollow journal 3 into the vdrying cyhnder and is dicated at 30, in the end wall 31 of the connection 14, before referred to. The pipe may be operated by a handleA 32, and preferably the pin is withdrawn from engagement with the wall 31* against the action of a coil spring 33.

When the stop pm is released, the si hon pipe 20 may be revolved by means of the andle 8 and, when its suction end 24 contacts `with the inner surface of the Wall of the .end ofthe pipe is raised or lowered toward or from the inner surface of the drying cylinder.

It will be observed that the distance between the two supports 21, 22 of the siphon pipe is very much less than the distance the pipe extends beyond the inner end of the sleeve and into the dryer, so that 'a comparatively small flexing of the pipe at the adjusting collar or ring 34 produces a considerable movement at the suction end of the pipe, To facilitate this flexing movement, the suction pipe may be, as shown, flattened at or close y adjacent the adjusting collar 34, as indicated at, 37.

The ad'usting screw may besu ported in any suita le manner, but referaly will be so arranged that the num r of turns given the screw will be indicated so that the operator can tell how far he has moved the suction end of the Siphon pipe. In the par ticular construction illustrated, the screw is provided with a thrust collar 38 in a recess, indicated at 39 in Fig. 5, formed inra boss 40 on the connection 14, before referred to'. Screwed into this boss is a plug 41, which has an inset portion 42 provided with a number of notches with which registers a spring linger 43 carried on a nut 44 turning with the screw 36. A lock nut 45 and packing 46 may be rvided for holding `the parts in assembled) position. As before stated, the slight movement given-the ipe by the adjusting screw produces a su cient movement in the cylinder, and this movement of the pipe in the inner end of the sleeve 12 may be provided for by slightly rounding the spider 21, as indicated at 47, see particularly Fig. 4, and this spider is also provided with passages 48 to permit the steam to'pass from the chamber lthrough the sleeve and into the cylinder journal 3.A

If desired, a collar 49 and packing 50 may be provided for effecting the steam joint between the'chambers 15, 17, before referred to, this collar and packing surrounding the siphon pipe and being held in steam-tight relation by the pressure of 'the steam in the chamber 15. n

The operation of the device is believed clear from the foregoing, but may be briey recapitulated as follows: When it is desired to determine whether the siphon is in proper position, the operator by manipulating the adjusting screw 36 may bring the end of the siphon pipe into Contact wit the-inner sur face of the dryer cylinder, and this he can readily determine by loosening and operf ating the handle 27. When he finds that the suctlon end of the pipe is in contact, he then turns the adjusting screvv7 36 a given distance in the opposite direction and thus by the aid of the notched disc can tell the exact position of the end ofthe pipe relatively to the inner surface of the cylinder, it being understood, of course, that each notch represents a certain distance that the end of the pipe is raised by the operation of the screw. It will be observed, furthermore, that these operations can all be done convenientl from the outside, thus greatly simplifying mspection and adjustment.

While the invention has been shown and described Ain its preferred form, yit will be understood that various changes maly be made in the specific construction emp oiyed for supporting and operating the sip on tube and that the invention is, therefore, not to be limited to. this specific construction, but that this can be changed as desired within the scope of the claims. f
