'ro ALL WHoM 1T MAY CONCERN;
Be it known that I, FRANK J; ROT, of Schenectady, State of New York, have invented certain. new auduseful Improvements in Piston-Packing; and I declare the following to he a full, true, and exact description of the same, reference being had to the accompanying drawings, and to the lctters'of reference marked thereon.
Figure 1 represents an end view of my invention, with the follower removed,
Figure 2 is a section view of the same. A.
'Figure 3 is a plan :view of the wedge to which the spring is attached.
Figures 4, 5, and 6 represent different vviews of the packing-rings This piston-packing is constructed to pack the cylinder with spring and steam-combined.
The body of the piston is composed of spider` A, follower B, and inner ring C, and when` screwed together The packing-rings D are made so' as to freely slip over the inner ring C, and are turned as near the size of the cylinder-as possible, and are constructed with a projecting edge on their outer space, as seen in iig. 4. This projection can be varied to correspond with thc presslire of steam in the cylinder. These rings are each divided into three dierent pieces or sections,and are held together by means ofv a dowel-pin, as seen in iig- 5. All of lhcjoints are fitted neatly together, with the exception of the lower ones, which are held apart by means of a V-shapedwedgc and spring, as seen in Iig. 3. This wedgeF and spring G can be used in three different ways, and for three different purposes: first, to keep the packing expanded; second, to /keep all other joints in vclose contactwith one another; and third, to shut ofi' all communication of steam from the inner surface,fand to support, in combination 'with the steam, the weightof the piston. In engines where the weight of the piston lis supported by the piston-rod, as in vertical-running engines,n the wedges have tou'bc placed in opposition to one y another, so as to keep thc piston as much as possible in the cent-re. v l
The rings E are fitted loosely over the inner ring C, butin such a manner as not to allow it much play.;
The inner face is turned so' as to form a steam-joint, with corresponding face of ring D, while the outer edge is bcvclled oFF, as seen in iig. 1,'so 'as when acted upon bystcam it is forced tightly against ring D. This ring E answers two important purposes: first, packing of this kind can -be applied to any piston without the alteration of thcispider and followcr;` second,.it acts as pack-ingl to pack-ring D, no matter how loose it may be. The rings E E can bc bored out somewhat larger than inner ring C, and cut out suiiicieutly, so that when acted upon by the steam they will close `upon the inner ring C, so as to prevent any steam fromvpassing-into the packing-rings.
There is but very small pressure required to' keep packing-rings steam-tight against the surface of Vthc cylinder, and all pressure above that i's disadvantageous, first, in reduction of'power, and second, in unnecessary wear of the cylinder and packing.
I The steam passes over follower or`spider, under the projecting edge of ringAD, and forces those rings gently against the inner surface of the cylinder, and at the same time forces rings E against the face of ring D, and by this means prevents vany steam from passing into the other rings. i
4 Having thus described my invention, what I claim, and desire to secure` by Letters Patent, is
The side-rings E E and packing-rings D D,vwhen combined substantially in lthe manner set forth. In testimony that I claim the above, Iafiix my signature in presence of two witnesses.
