STEAM JOINT.

Application led May 24, 1924. Serial No. 715,696.

To all 1li/10m. it may concern: i I, CHARLES H. ltlAnRn'r, a citizen of the United States, and a resident of the countypose of the condensation thereby permitting the run of the dryer to its maximum capacity.

With these and other objects in view, my invention consists in the combination of parts shown in the accompanying drawing `fold at the fiange the plate 14 is locked into..

-'to move longitudinally and sideways. It is and described in the specification and more particularly pointed out in the claims.

In the appended drawing,

Figure 1 is a longitudinal section through the steam joint, one line 1-1, Figure 2,l

Figure 2 is an end elevation,

Figure 3 is a section on line 3--3, Figure 1, and

Figure 4 is a section on line 44, Figure 1. Y

Referring to the drawin 10 is a manifold used with rotary dryers o the type referred to, which has a plurality of radiating steam passages 11 and condensation passa es 12. (These passages are indicated in fu in Figure l and in dot and dash lines in Figure 4.) The steam passages 11 f the manifold radiate from a central chamber 13 which is open on the outer face of the manifold. The manifold is recessed at the chamber to receive a plate 14 of the steam 'oint. The plate 14 also fits a recess at the dange '16 of the housing 15 of the, steam joint. When the housing 15 is secured to the manithe recess before referred to.

Thehousing 15 has a steam chamber 17 and a condensation chamber 18. Through thesaid chamber 18 passes a tube 19 which is screwed with one end into ,the wall 20 of the housing 15; the other end 'of the tube passes through the plate 14 and enters the chamber 13 of the manifold. The wall 20 carry off the condensation that is delivered lines into which the tube 19 is screwed separates the steam chamber 17 from the condensation chamber 18, which chambers, as will be noted, are aligning.

Preferably. an additional bearing surface is provided for the end of the tube 19 at the plate 14, by forming ribs 18 in the enlarged portion of the condensation chamber 18 which enlargement is at the ange 16 of the housing; the number of ribs 'being preferably the same as there are condensation passages 12. Therefore, the enlarged portion of the condensation chamber 18 is divided by the ribs into as many sections as there are radiating condensation passages 12 and each of them is connected to a respective section formed by the ribs 18', by a nipple 21. (See Figures 1 and 4.)

The housing 15 bears snugly in a stationary sleeve 22 and through which the said housing 15 projects. The sleeve 22 has an annular chamber 23 which leads to a threaded opening 24 adapted to receive the steam pipe through which steam is admitted to said annular chamber 23. The housing 15 hasa series of openings 24 which establish communication between the steam chamber 17 and the annular chamber 23. Through the said openings, therefore, steam is supplied from the annular chamber to the steam S5 chamber 17 of the housing.

The sleeve 22 has another annular cham, ber 25 which leads into a threaded opening 26 to which a pipe may be connected to to saidannular chamber 25 through a series of openings 27 provided in the housing 15. These openings 27 establish communication between thev condensation chamber 18 and the said annular chamber 25.

The sleeve 22 has lugs 27 which bear in slots of a fork 28 so that the sleeve, and

therefore the housing, can move up and A down in said slots of the fork. The fork is connected by a ball and socket joint 29 to a stand 30. The ball and socket joint permits the sleeve, and therefore the housing,

and the sleeve, packing glands 31 are pro- 110 vided at each end of the sleeve 22. Studs 34 connect the y,glands to the sleeve.'` The proper register of the openings 24 and 27 with the corresponding annular chambers 23 and 25, during of the housing, preferablyy providedA near` the front end of the 'steam joint. The'collar is prevented from vturning by securing it to extensions of a pair of studs 34 at the adjacent end. These means, as will be seen, will permit the rotation of the housing `of the sleeve but prevent any relative longitudinal displacement of the sleeve and the housing.

It is apparent that the plate 14 separates the steam chamber 13 of the manifold from the condensation chamber 18 of the steam joint. In consequence, there is no back pressure at the point where the condensation is delivered by the manifold to the condensation. chamber l8. Therefore, the condensation from the manifold is delivered not only by gravity but also by the pressure of the steam which comes from the chamber 17, passing through the manifold and dryer as it tend-s to pass out into the condensation passages 12 of the manifold before it can leave. This construction increases materially the ecency of the dryer, particularly when it is run to its maximum capacity, for

the heavy condensation caused 'in such instances is not blocked in the passages of the dryer bythe back pressure at the condensation chamber of the steam joint housing, but, on the contrary, is forced ahead to said chamber 'by the tendency of the steam to flow from the inlet 24 in the sleeve 22, to the outlet 2 6 of the said sleeve.
