Specification of Letters Patent.
I Application filed February 19, 1907. Serial No. 358,324.
=Patented May 19, 1908.
To all whom it may concern:
Be it known that I, JOHN S, CHAMBERS, a citizen of the United States, and residentof Wilmington, in the county of New Hanover and State of North Carolina, have invented a new and useful Improvement in Steam- -.Tight Joints for Rocking or Rotary Rods;
' of which the following is a specification.
' extended bearing for the rod within the pack-' Theobject of my invention is to provide a steam-tight joint for rocking or rotary rods, the said oint being so constructed as to take up end thrust on the said rod and to form an in box.
I/Iy invention consists more particularly in providing the rockin or rotary rod with a plurality of annular s oulde'rs formed by one or more circumferential flanges on the rodemb'edded in the metal filling of a packing box for producing the results above set forth. Practical embodiments of my invention are represented in the accompanying draw-' in s in which igure 1 represents in side elevation my nove steam-tight joint applied to the operating rocking rod of a throttle valve at' that point where the rod passes through the side .wall of the steam dome. Fig. 2 represents the steam-tight 'joint and its adjacent parts in longitudinal central section, the metal filling being shown in half section, and Fig. 3 re resents my steam tight joint applied to t e rotary operating rod of a globe valve, certain of the parts bein shown in vertical central section, the meta filling being shown in half section.
In Figs. 1 and 2 the wall of the steam dome I is denoted by 1 and into this wall is screwed rockin rod 4within the packing box 2, '3,
which ling is Babbitt metal or other suitable metal composition or metal, and may be made solid or in sections as desired.
The rocking rod 4 is provided with aplurality of annular shoulders engaging the metal filling within the packing box for forming a steametight joint at this point. This arrangement also prevents all longitudinal movement of the rod under the influenceof endwise thrust and also gives to the, rod an extended bearing within the packingbox. The plurality of annular shoulders on, the rocking rod-may be formed by providing the rod with one or more tapered circumferential flanges 8. In the present instance three of these flanges are shown as embedded in the metal filling 7.
In Fig. 3, I joint applied to the rotary rod -9 ofa globe valve 10, which rod extends through theplug 11 and cover 12 of a packing box and has the circumferential tapered flanges 13 which form the annular shoulders, embedded in the.
have shown the steam-tight metal filling 14 of tliesaid packing box 1 1,12.
The boreof the plu of the packing box is made flaringand the Ivore of the removable cover is also made flaring as shown, so that by screwing in the cover, the metal filling may be forced inwardly around the shaft to take up any wear at this point.
What I claim is:
1. A steam-tight joint for a rocking or rotary rod comprising a metal filling surrounding the rod and annular shoulders on the rod embedded in said metal filling.
2. A steam-tight joint for a rocking or rotary rod comprising a packing box through which the rod extends, a metal filling for the box, surrounding the rod, and annular shoulders on the rod embedded in said metal fillmg. a I j 3. A steam-tight joint for a rocking or retary rod comprising a metal filling surrounding the rod and a circumferential flange on the rod embedded'in said 'metal filling.
4. A steam-tight joint for a rocking or rotary rod comprising a packing box through WlllCh the rod extends, a metal filling for the box, surrounding the rod, and a circumferential flange on the rod embedded in said metal filling. r
5. A steam-tight joint for a rocking or rotary rod comprising a metal filling surrounding the rod and a ta ered circumferential flange embedded in sald metal filling.
6. A steam tight jointfor a rocking or ro tary rod comprising a packing box through which the rod extends, a metal filling for the, box, surrounding the rod, and a tapered circumfer'ential flange embedded in said metal filling.
7. A steam-tight joint for a rocking or rotary rod comprising a metal filling surround- I of a hollow p .WhlCh the ro box, surrounding the rod, and ta cred circumferential flanges on the rod em edded in ing the rod and a plurality of circumferential flanges embedded in said metal filling.
8. A steam-tight joint for a rocking or rotary rod comdprisinga packing box through which the r'o extends, a metal filling forthe box, surrounding the 'rod, and a (plurality of circumferential flanges on the ro in'said metal filling.
' '9. A steam-tight joint for a rocking or rotary rod compr sing a metal filling surrounding the rod and a plurality of ta ered cirembedded cumferential flanges on the rod em edded in .said' metal fillin 10. A steam-tight joint for a rocking or rotary rod comdprislng a packing box through extends, a metal filling for the flaring bores and a metal filling for the box, surrounding the rod, the cover of the box being arranged to force the metal filling in- Wardly to take up Wear at this point.
13. A steam-tight joint for a rocking or rotary rod-corn rising a packing boxgcomposed of a hollow p ug and cover, said lug having a flaring bore, a metal filling for-t e box, surrounding the rod and annular shoulders on the rod engaging said metal filling, the cover of the box being arranged to force the metal filling inwardly to take up Wear at this point,
14. A steam-tight oint for a rocking or rotary rod comprising a packing box com osed of a hollow plug and cover having aring bores, a metal filling for the box, surrounding the rod and annular shoulders on the rod engaging said metal filling, the cover of the box being arranged to force the metal filling inwardly to take up Wear at this oint.
In testimony, that I claim t e foregoing as my invention, I have signed my name in presence of two Witnesses, this 14th day of February, 1907.
