EDWIN D. BANGS, OF MILWAUKEE, WISCONSIN, ASSIGNOR OF ONE-HALF TO WILLIAM FINGER, 0F MILWAUKEE, WISCONSIN.
ROD-PACKING.
To all whom it may concern:
Be it known that I, EDWIN D. Bar es, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Rod-Packing; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention has for its object to provide a simple and economical steam-tight met-allic packing particularly designed for pistonrods, valve-stems or other reciprocatory members, the arrangement and construction being such that by the employment of two or more ductile metal rings, one of the same may be indented in its side face by the use of a spreading tool whereby said ring is expanded at this point together with the ring which it engages and will thus flatten to compensate for a corresponding flattened. or irregular surface of the rod to which it is applied, whereby a tight joint is effected.
With the above object in view the invention consists in certain peculiarities of con struction and combination of parts hereinafter described with reference to the accompanying drawings and subsequently claimed.
In the drawings Figure 1 represents an end view of a stutfing-box and rod provided with a packing embodying the features of my invention, the view being partly in section as indicated by line l1 of Fig. 2, and Fig. 2, a longitudinal sectional view of the same with parts broken away and parts in section to more clearly illustrate the structural features of the packing members.
Referring by characters to the drawings, 1 represents a stuffing-box at the end of a steam cylinder, and 2 a gland that enters the stuffing-box, the base of the stuffing-box and corresponding end of the gland being provided with oppositely beveled faces 3, 4. Mounted in the stuffing-box is a reciprocat-ive pist0n-rod 5, which rod for con venience in illustrating the invention, as shown in Fig. 1, has a flattened or worn face 5 Under ordinary conditions when a rod has become worn or flattened as stated, it would either have to be removed and turned down or when packed the rings of usual type could not be contracted sufficient to compensate for this wear and hence there would be more or less leakage at the flat- Speeification of Letters Patent.
Application filed April 18, 1911.

Serial No. 621,810.
tened or worn portion of the rod until such time as the packing had firmly set or conformed to the irregularity by tightening said packing from time to time. My improved packing will overcome this objection and when applied will be instantly expanded to conform to any irregularity or wear of the rod.
As shown in Fig. 2, a ring A having a tapered face is first fitted to the rod and. seated against the tapered face 4 of the stuffing-box. Thereafter a second ring B having an internally tapered face is fitted to the flat face of ring A. A third ring 6, which ring is preferably formed of ductile metal, is next slipped upon the rod, the said ring being provided with a tapered face 7 which is adapted to nest with the internal tapered face of ring B. The ring 6 is provided with a flat end-face S, which flat endface is merged into an inclined face 9 that intersects the bore of the ring, said inclined face 9 being disposed in the same direction as its outer inclined face 7. The ring 6 of ductile material is also diagonally split as indicated at 10, whereby the same may be expanded or contracted. A master ring 11 is next slipped over the rod, which ring is diagonally split, and is provided with oppositely inclined faces, one of the same being in matched engagement with the inclined face 9 of ring 6. Should the shaft be worn or flattened as shown at 5, the mechanic, with the use of a proper tool, will then make an indenture as indicated at w, in the flat side face 8 of ring 6. This indenture formed in the ductile metal will cause the said ring to spread inwardly and radially of the rod whereby the master ring is flattened opposite the point of the indenture.
Thus said master ring, which is also of ductile metal, and ring 6 will be flattened at the point of wear, as shown in Fig. 1, and thereby insure a tight packed joint between the rod and rings aforesaid. This operation may be repeated opposite as many points as there may be irregularities in the piston-rod and after their completion a ring 6 is adjusted against the inclined face of the master 11, the ring 6 being in every way similar vto the ring 6. A ring B is then fitted to the inclined outer face 7 of ring 6' and a second finishing ring A is thereafter abutted against the ring B as shown, the ring A being similar to ring A and the inclined outer face of the ring A is thereafter engaged by the gland 2 which is inserted into the gland in the position shown in Fig. 2. Thus the assembled packing is completed.
The essential elements of my improved packing are the master ring of ductile material and the overlapping rings 6, 6, it being understood that, in some instances, these overlapping rings may be used without the follower rings B, B, C, C, but in order to insure the greatest efliciency and wear the entire assemblage of rings as shown are preferable.
I claim:
In a reciprocative rod having a supporting stuffing-box and gland each of which is provided with beveled faces disposed at opposite angles; the combination of a beveled ring fitted about the rod and seated to the beveled face of the stufling-box, a second ring seated against the first named ring the second ring being provided with an internal beveled face, a similar pair of rings one of which is fitted to the beveled face of the Copies of this patent may be obtained for gland, an obliquely split ductile master ring fitted to the shaft between the aforesaid rings, the master ring being provided with oppositely beveled peripheral faces, a pair of obliquely split ductile metal rings, each being provided with a flat side face intersected by an inwardly tapered face fo-rnested engagement with the master ring, that ring of the pair which is farthest from the gland being provided with one or more indentures in its flat side face to effect a radial spread whereby the inner circumference of said ring is contracted, together with the master ring at the point of indenture to compensate for irregular wear in the rod to which the packing rings are applied.
In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee in the county of Milwaukee and State of Wisconsin in the presence of two witnesses.
