Lette/rs Patent No. 97,564, (lated December 7, 1,869.
rMPRovEMx-:NT IN PIsToN-PACKING.
-hoh"- The Schedule referred to in these Letters Patent and making part of the neme.
Thel vnature of my invention consists in covering theI joint of piston-packing;rings, by `making in the ring a recess at its joint, and 4then placing in it a plate or section' of a ring, which ofthe same diameter as the outside diameter ofthe packing-ring, but less in thickness and width, (when-viewedin cross-section,) said plate or section of a ring being so suspended or held in said recess in the packing-ring as that a space shall be left between the walls of the recess and the inner edge, ends, and outer surface of said plate or section of a ring, which space is lled by pouring into it `a molten-metal or alloy, thereby making a perfect steam-tight joint.
To enable others skilled in the art to make and use myinvention, I will proceed to describe'its construc In the accompanying drawings, which form part of my specification Figure 1 is a sidel elevation of my improvement in fitting a' compound joint in a, metallic ring, for pistonpacking.
Figure 2' is a top view of the' same.
Figure 3 is a side elevation of the same, representing a recess in the piston-packing ring.
Figure 4 is a side view of the plate or section of a ring, used in forming the steam-tight joint.
Figure 5 is a top view ofthe same.
In the accompanying drawingsl A represents a section of an ordinary metallic ring, used for forming the ordinary expansive metallic packing for pistons of steam-engines, &c.
X represents the joint which Ais made in the ring, for the purpose of allowing it to expand.
` This joint X is often covered by a plate, fitted and` secured to the ring.
-The joint X is also covered by forming what is Y known as a compound joint.
Both of these modes, require great care and much trouble and labor in fitting, and are very expensive modes of covering the joint X.
'lo avoid this labor, trouble, and expense of covering the joint X, I make in the ring, directly opposite to the joint X, a recess, B, as shown in iig. 3.
In this recess I suspend the plate C, (the plate being smaller than the recess,)' so as to leave a space between `the walls of the recess B and the inner edge, ends', and Aunder-surface of the plate-0, as indicated at fm, in'gs.
1 and 2.
By placing blocks of wood on each side of the-ring A, as indicated bythe dotted lines 1), and suspending vthe plate in the recess, in the manner before stated,
and shown in the accompanying drawings, Vthe molten metalby preference, Babbit metal -or a suitable alloy, maybe poured 'into' the space m, and the molten metal running up into openings s, will cause the plate 0 to be attached to one side of the fillingl or metal poured in the space m. a
After the metallic filling` has become sufficientlyccld or congealed, the blocks' indicated by the dotted lines are removed.. and the filling in the space m is cut through, as indicated at "a and u', so that ythe plate O v n .may slide or move in one portion f the metallic tilling, thereby allowing the ringtoexpand, and at the same time keeping the joint Xcovered by the plate.
The skilful machinist will readily understand how the space m may be lle'd with the molten metal, and
-will easily devise the means for doing so, from the suggestions herein given.
Having thus described the nature, construction,l and operation of my improvement, A.
What I claim, as of my invention, is- Making a recess in a packing-ring, at its joint, and using, in combination lwith said recess, a plate, and a metal or alloy-filling, as herein described. EDWARD SULLIVAN.
