Description: |
| Abstract:
This invention is illustrated in the accompanying drawing, which forms a part of this specification, and in which the figure represents a section through the center of the valves, cylinder, and head, showing the relation of the valves to said cylinder and head and to each other. It also shows the forms and relations of the parts adjacent to the valves, the seat of the steam-valve being entirely within the cylinder, and no part thereof being recessed into the head, and the seat of the exhaust-valve being in the cylinder so far as the bearing-surface is concerned, but a large part of the cavity being recessed in the head of the cylinder. The valves are inserted and removed by an endwise movement.
Claims:
1. In a steam or gas engine, the oscillating steam-valve D, working in a circular cavity, and having its seat formed entirely within the cylinder, and always open for the access of steam, and having also gridiron bars and passages, as shown, combined with corresponding gridiron bars and passages in the cylinder, and the steam-inlet passage formed in the cylinder-head, as set forth.
2. The exhaust-valve described, having its seat formed in the cylinder and its recess or cavity formed largely in the cylinder-head, the said valve being always open to the cylinder for the exit of water of condensation and exhaust, but having gridiron bars and passages to correspond with the ports in the cylinder, as set forth.
3. In a steam-engine, and in combination with a cylinder in which the inlet k and exhaust-passages k', are formed entirely in the cylinder head and in line with the travel of the piston, the inlet-valve having its recess and seat formed entirely within the cylinder always open for the access of steam, and having bars and passages to correspond with similar bars and passages in the cylinder, and the exhaust-valve always open to the cylinder, but having bars and passages, as shown, the said valve having its seat in the cylinder and its recess largely in the cylinder-head, as and for the purposes set forth.
