nnrrnn nnw'nnn To all who/m it may concern:

Be it known that l, EDWARD Ci-nnnns CoL- soN, citizenot the United States, residing at Chicago, in the county ot Coolr and ,State ot Illinois, have invented certain new and useiiul improvements in Steam-Pipe-Joint Connections, of which the following is a specitication.

This invention relates to improvements in steam pipe joint connections and is especially designed for use in connection with steam heated rolls, such as paper calendering rolls, ironing or mandrel rolls and finishing rolls for linishing cloth.

One of the objects of the invention is the construction of an improved steam joint adapted to allow for an irregular movement of the heating rolls with which it is ber adapted to hold the joint steam tight connection with the rolls.

Another object ot the invention is to provide a steam pipe joint adapted for use in connection with heating rolls with means arranged therein adapted to hold the joint steam tight under all conditions and to allow for the vertical and lateral movement of the roll which is connected to it.

W ith the above and other objects in view the invention embraces certain combinations, constructions and arrangements of parts, clearly described in the following specilication and clearly illustrated in the accompanying drawings, in which Figure 1 is a central longitudinal sectional view or" the improved steam joint showing the saine in normal position, Fig. 2 is an end view thereof, Fig. 3 is a central longitudinal sectional view showing the steam joint in the position it would occupy it the roll to which the joint is attached should settle or be moved, F ig. 4 is a detail sectional view, on an enlarged scale, of a casing, Fig. 5 is a detail plan view of a gland member, Fig. G is a detail end view of a movable float member adapted to hold the joint steam tight under all conditions, and F ig. 7 is a detail side elevation of the lioat.

Referring to the. accompanying drawings, which are merely illustrative of one form of the invention, 1 denotes a hollow steam ironing or polishing roll, on the outer end of which a casing 2 is suitably connected by means of screws or other fastening means, not shown. The casing 2 is formed with internally projecting spaced annular flanges or shoulders 3 and et. The flange or shoul- Speccaton of Letters atent.

der 3 is formed with a beveled inner surface while the flange is termed with a surface adapted to occupy a position normally parall el with the axis ot the roll 1.

A. float member 5 projects into the bore ot' the roll 1, said member being formed with a rounded enlarged head t5, engaging with an annular or tubular projection 7 on the inner end of the casing` 2, which tubi.- lar projection surrounds the rounded head 6 and is formed with inclined ports S, spaced apart thereon. rEhe outer end ot the float member 5 is termed with a head 9, very much larger than the head (i, and said head 9 is adapted to engage with a holding gland 1,0, which is secured by means oipv screws 11 to the casing 2. The head 9 is formed with a convex outer surface and the gland 10 is formed with a concave inner surface, whereby the head can have close movement against said gland and be in positive contact with the same at all times. The gland 10 is formed with an opening 12, which has an inclined wall, and is provided with balls 13, located in a ball race 1i, having a hardened bottom washer 1.5 therein. rlhe gland 10 is also termed with laterally extending oil ports 1G, whereby the conv surface of the float head may be lrcpt constantly lubricated, oil being supplied through said openings by means ot an oil cup 17, located on the gland 10.

.it steam inlet pipe 18 is threaded on to the head S ot the float and on its outer end carries a tee litting 19, tlneadcd thereon. vWithin the bore of the pipe 18 an exhaust pipe projects, said pipe passing into the bore oit roll 1 beyond the inner end ot the tubular extension 7, ot the casing 1. rlhe outer end ot the exhaust pipe Q0 is threaded to the tee iitting 19, which is provided with an ii'iternal partition A cone washer 22 normally holds the balls 13 in place in the race 14, and said cone washer is normallyv held against said ball 13 by means ot a spiral spring positioned around the pipe 1S and engaging at its outer end a bearing washer i, movable on a nut adjustable on the pipe 1S, which is provided *ith screw threads tor this purpose. Normally the pipes 1S and 2O occupy a position parallel with the a2-:is of the roll 1, but when the roll should be moved the float member 5 and the pipes will be forced to an angular position, the tloat member by contact closely with the gland 10 taires up all looseness which normally might occur. This member is held in positive engagement with the gland 10 by the pressure of the steam in the pipe l, which is exerted against the inner side of the head 9, of said member 5. No matter to what angle the roll 1 may be moved the joint will be held steam tight by means of the float member 5. The float member1 5 is adapted, with the assistance of the spring 23, to hold the pipes 18 and 20 normally in a center position, in this way the float 5 acts as a centering device.

Having described my invention I claim l. In combination, a hollow casing conuectible to a. hollow heating roll, a gland secured to the casing, a float member movable against the gland and the casing, a steam inlet pipe threaded to the float member and a steam exhaust pipe projecting within the inlet pipe.

2. In combination, a hollow casing connectible to a hollow heating roll, a gland having a concave inner surface mounted on the casing, a ioat memberv having a head formed with a convex surface engaging with the concave surface of the gland, an inlet steam pipe connected to the gland, and an exhaust steam pipe projecting through the bore of the inlet pipe.

3. In combination, a hollow casing having a tubular extension connectible to a hollow heating roll, a float member formed with a rounded head engaging with said tubular extension, said float member having an enlarged head with a convex surface, a gland secured to the casing having a concave surface engaging with the convex surface of the float member, an inlet pipe threaded to the float member and an exhaust pipe projecting through the bore of said float member.

4. In combination, a hollow casing connectible to a hollow heating roll, a gland secured to the casing, a float member engaging with the gland, a steam inlet pipe connected to the float member, balls located on the gland, a cone washer engaging the balls, a spring engaging the cone washer, an adjusting nut threaded on the inlet pipe engaging the spring, an exhaust pipe within the inlet pipe, and a tee fitting connected to the outer ends of the pipes having a spacing partit-ion therein.
