JOHN DYKEMAN AND JASON G. OORBIN, QF RONDOUT, NEW YORK.
PISTON.
SPECIFICATION formingpart of Letters Patent No. 255,262, dated March 21, 1882.
Application filed January 6, 1882.
To all whom it may concern Be it known that we, JOHN DYKEMAN and JASON G. CORBIN, both of Rondout, in the county of Ulster and State of New York, have invented a new and useful Improvement in Piston-Packings, of which the following is a full, clear, and exact description.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a plan view of a piston to which our improvement has been applied, the face plate being removed. Fig. 2 is a sectional elevation of the same, taken through the line w as, Fig. 1,the face-plate being shown in place.
Fig. 3 is an elevation of apart of the packingring, showing thejoint and its tongue.
The object of this invention is to promote durability in piston-packings.
The invention consists in the combination, with the openv single-ring piston-packing having cross-ribs and the end of a web of the piston-head, of a curved plate and a U plate attached thereto, whereby key-plates to center or litre the piston can be received and held, as will be hereinafter fully described.
A represents a piston-head, which is made with a hub, B, to receive the piston-rod, and with radial webs G to support the face-plate D, and having screw-holes in their enlarged outer ends to receive the screw-bolts E, that secure the said face-plate D in place.
1 F is the packing, which is made in the form of an open ring, and is held out so as to bear against the inner surface of the cylinder by one or more open ring-springs, G,placed at the inner side of the said packing-ring F. The
(ModeL) is attached a U-shaped plate, K, to receive the enlarged end of one of the radial webs, G, as shown in Fig. 1. With this construction in the case'of horizontal cylinders, when the packing wears the piston can be lined or centered by inserting thin keyplntes between the U- plate K and the end of the web 0. In the case ofvertical cylinders the plates J K are not required.
We prefer to join the ends of the packingring on an angle, as shown in Fig.3, to avoid wearing ridges or channels on the inner surface of the cylinder.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination, with the open single-ring piston-packing F, having ribs I, and the end of a web, (1, of the piston-head, of the curved plate J, and the U-shaped plate K, substantially as herein shown and described, whereby key-plates to center or line the pistoncan be received and held, as set forth.
JOHN DYKEMAN.
