IMPROVEMENT IN FEED-WATER REGULATORS FOR STEAM-BOILERS.
Specification forming part of Letters Patent N 0. 197,258,
dated November 20, 1877; application filed May 10, 1875.
To all whom it may concern:
Be it known that I, N. T. EDSON, of New Orleans, State of Louisiana, have invented a Feed-Water Regulator for Steam-Boilers, of which the following is a specification:
The object of my invention is to indicate the height of water in the boiler, to regulate the supply of feed-water, and to cause an alarm in case of failure of proper supply.
Figure 1 is a front view of my indicator and regulator, composed of shaft A, to be screwed into the boiler or otherwise made stable, at a level a little below a proper water-line, and lever B, composed of steam-pipe G and waterpipeD, weight 0, and steam and water vessel d. The lever is fitted with a steam-tight joint onto and near the outer end of shaft A. The rod 0 pivoted to the lever, is intended to be put in connection with a whistle, and rod b with the feed-water valve.
The weight c'should be sufficiently heavy to trip the valve and blow the whistle, and the vessel d, at the opposite end of the lever, sufficiently large so that when half full of water the lever will be balanced. The shaftA should be so located that when the water in the boiler is at a proper height the vessel 01 will. be half full of water and the lever horizontal.
If the water in the boiler is raised above a proper height it will flow into the vessel d, causing that end of the lever to descend, and thereby cause rod 1) to close the water-feed valve. If the water in the boiler falls below a proper level, it will flow out of the vessel, and the weight will cause that end of the lever to descend, and thereby cause rod' b to open the water-feed valve. If, from any cause,
the water in the boiler continues to fall, with the valve open, the rod a will open a valve to the alarm-whistle.
e is a glass tube connected with the steam and .water pipes 0 and D, to indicate the height of water in the boiler and showwhether the lever is in action.
Fig. 2 is a sectional View of shaft A. f is a steam-passage, which forms a connection with steam-pipe O; and g, apassage which forms a connection with water-pipe, D at the junction of shaft A and lever B.
If the interior of the boiler will admit of it, shaft A is screwed into the boiler with pipe h in its end, and pipe J dispensed with. If not admissible, passage f terminates at its junction with steam-pipe J, the upper end'of which passes into the boiler.
I do not confine myself to the attaching of weight 0 directly to lever B, as the same results can be produced by connecting a cord to the same, and to the lever O or D, and passing it over a pulley, and connecting it to aweight.
I claim as my invention 1." Shaft A, with its steam and Water passages f and g, in combination with lever B, com osed of steam and Water .pipes O and l), vesse d, and weight 0, as and for the purposes specified.
2. The combination of the glass tubecwith shaft A and its steam and water passages, and with steam-pipe O and water-pipe D, substantially as and for the purposes set forth.
N ATHL. T. EDSON.
