T0 WHOLWI IT MAY CONCERN:
Be it known that I, JAMES U. ADAMS, oLRichiield, in the county of Genesee, and State of Michigan, have invented a new and useful Improvement in Piston-Heads for steam-engines; and do declare that the following is a true and accurate description thereof', reference being had to-the accompanying drawings, and to the letters vf-reference marked thereon, and 4being a partei' this speciiication.
Figure lvis a perspective view. l
Figure 2 is asectional view.
Figure 3 is a top view.
Like letters indicate like parts in each figure. Y
To the4 piston-rod'A is iirmly secured `head B, suiiiciently chamfered at the periphery' to receive metallic packing-rings D, secured in position by springs E and screw F.
The head Bis constructed in'size nearlylthe diameter of the bore 'of the cylinder, to allow the :same to reciprocate freely, but not loosely, in the same, bythe pressure of the steani against the rings, adjusting the same to the full calibre, thereby preventing any waste or leakage between the rings and sides of the cylinder.
Rings D are severed by sawing vertically tothe centre from opposite directions at some distance apart, as shown by G G, allowing space between, as at H, where is inserted a plate'ot copper, first prepared by plating one side of the same, securing a more perfect adhesion to the metal, the opposite side separating, leaving a smooth and parallel joint, thereby preventing the passage of steain, and allowing the expansion of the rings, as before described. i y
Springs E prevent any disarrangement of the rings by their equal pressure, and allow the same 'to contract or expand, as required, by the action of the same, thereby forming a very perfect and convenient device for the purpose t described.
What I claim as my invention, and desire to secure by Letters Patent, isl- 1. 'The springs E and rings'Diu combination with piston-head B, substantially as described.
2. The copper, H, or other metal, inserted in the manner described, and for the purposes specified.
JAMES UL ADAMS.
