ROD PACKING-RING.
Specification of Letters Patent. 7
Patented J an. 9, 1917.
Application filed February 28, 1916. Serial No. 80,880.
To all whom it may concern Be it known that I, CLARENCE E. MOORE, a citizen of the United States, residing at Virginia, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Rod Packing-Rings, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention consists of certain improvements in pracking rings and relates especially to pac 'ng rings as used upon re: ciprocating rods, found in steam engines or the like.
The object is to provide a leak proof joint at the abutting ends of the ring, for as is well known such rings are divided and in the embodiment of my improved joint I prefer to have the ring divided into a plurality of equal parts, preferably four, however such division forms no part of my present invention, as it is well known in the art.
In the drawing forming part of this application, and in which like reference characters indicate like parts: Figure 1 is a cross sectional view through the center of the ring and at right angles to the axis thereof. Fig. 2 is an external circumferential view of same. Fig. 3 is an axial cross sectional view, and Fig. 4c is a perspective view of the interlocking cap.
1 represents a reciprocating rod about which the ring 2 is designed to snugly fit and form a tight joint.
3 is a portion of a container or housing in which the ring 2 is held against longitudinal movement with the rod and which is of the usual form for metallic packing rings.-
The abutting ends of the ring 2 each has a channel or slot 4 cut longitudinally therein and which slots are directly opposite each other when the sections of the ring are alined in position. Into these slots is designed to fit the filler block 5 which has formed inte gral therewith the cap 6, and the ends of which latter terminate flush with the ends of the block while the sides extend beyond the sides of the block to a point in exact alinement with the sides of the ring. Within the upper surface thereof and longitudinally the center of the cap is formed a semicircular groove or seat 7 for the reception of the continuous circular spring 8 which extends entirely around the ring when assembled, the bottom of the seat 7 being some what above a'plane with the under side of the cap 6.
The complete ring when assembled with the abutting ends of the various sections touching each other, is of a diameter considerably less than that of the rod 1 so that when applied thereto, there will exist spaces 99 intermediate the ends thereof and similar spaces intermediate the ends of the filler block and the ends of the channels 4 to provide means for contraction of the ring to compensate for wear.
The spring 8 surrounds the ring and engages the seats 7 in the caps 6 and the former extending beyond the surface of the ring will cause abnormal pressure to be exerted upon the caps, the spring touching only the caps, and the ring at points intermediate the caps, this being for the purpose of insuring a tight fit of the caps where they engage the outer surface of the ring as well as the piston engaging surface of the block 5 and to produce as nearly as possible an equal wearing away of the various surfaces of the assembled ring.
The uppermost faces of the sides of the caps are inclined downwardly as at 10 to improve the accessibility of the spring during adjustment thereof and the spring is of the ordinary spiral type used for similar purposes and having ends which hook together to form a continuous member.
Thus I have formed a reciprocating rod packing ring made of a plurality of sections and having interlocking leak proof sections which bear upon the rod and upon the ring and means for equalizing the wear upon the varlous parts.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
1. The combination with a packing ring composed of a plurality of segmental shaped sections having oppositely disposed through slots in the ends thereof and an endless contractile spring for holding the sections together, of segmental shaped filler blocks intermediate the ends of the sections extending within the through slots and whose outer and inner walls are concentric with the bore of the sections, the outer wall being in the form of a seat for the contractile spring and of a diameter greater than that of the outside of the sections, and flanges on the sides only of the filler blocks for covering the space at the sides thereof intermediate the adjacent ends of the sections.
2. A packing ring for reciprocating rods comprising four identical segmental shaped sections having through rectangular shaped radial slots formed in the adjacent ends thereof, segmental shaped cooperative filler blocks formed concentric with the sections and designed to snugly fill laterally but not longitudinally the slots in the ends of the sections, laterally projecting flanges formed integral with the block and projecting flush with the edges of the sections and tightly covering the space between the adjacent ends 'J. E. MCCARTHY,
B. J. KANTER.
