Oscillating Steam Engine
|
John Albert Reed |
New York, NY |
Abstract:
The method I have devised for the introduction and escape of the steam is much more simple than any heretofore used, within my knowledge, and saves much friction and much expense in construction and use of the engine. To carry into effect my discovery and improvements I make ports and valves on both sides of the common oscillating cylinder, through which the steam enters the cylinder on both sides at the same time and from points opposite each other and thus the steam counteracts and balances itself and prevents the friction which is occasioned by taking in the steam on one side only at a time. An engine with a cylinder with my improvements for the induction and the eduction of steam, I denominate an antifriction oscillating engine. The trunnions on which the cylinder oscillates are made conical" and tapering from the cylinder with a screw in the end of each trunnion to tighten the valve and compensate for the wearing by the friction, should the friction, in its bearings render it necessary. To allow the valve and steam chest to be moved nearer to the valve seat on the cylinder, when necessary to prevent the waste of steam, make the holes to receive the bolts to secure the steam chest and valve in their place in the form of a slot.
Claim:
The arranging and placing the valves and steam ports on each side of the cylinder, and in combination therewith, so as to let the steam in on both sides of the cylinder at the same time, at opposite points, so as that the steam from opposite points may meet in the cylinder and so balance the pressure as to prevent that severe friction which is occasioned by letting the steam in on one side only of the cylinder at a time. |
