Q ROYAL E. DEANE, OF BROOKLYN, NEW YoR'K.

Letters Patent No. 90,934, dated June 8, 1869.

DRAUGHT-REGULATOR FOR HEATING- APPARATUS The Schedul referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, ROYAL E. DEANE, of Brooklyn, Kings county, New York, have invented, made, and

. applied to use a new and useful Draught-Regulator for Heating-Apparatus; and I do declare the following to be a full, clear, and correct description of thesame, reference being bad to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a side elevationof my draughtregulator.

Figure 2 is a longitudinal section of the same.

Figure 3 is a transversesection of the same.

In the drawings, like parts of the invention are designated by the same letters of reference.

The nature of the present invention consists in certain improvements, as more fully hereinafter set forth, in the construction of a draught-regulator for heatingapparatus'for heating dwellings and other buildings,- the object of the invention being .the production of a draughtregulator that shall be reliable in its operation,.and one constructed at a low cost.

To enable those skilled in the artsto make and use my invention, I will describe the construction and oporation of the same.

A shows an oblong box or case, formed of any suitable metal, in which are contained the operative parts of my apparatus, which box or case has one end closed, while the opposite end may he left open, and upon the sides of which box or case, placed centrally, are the openings B, in which are inserted two collars, through which pass the pipes leading from the heating-apparatus and to the chimney.

Within this case or box A is placed a secondary case or-box, Q, made considerably smaller than the case or box A, so that there shall he a certain amount of spaceintervening btween the interior of the outer case A and the exterior surface of the inner case 0.

The interior case 0 is provided with a steam-chainber, D, formed by enclosing a portion of it beneath a curved plate of metal, E, which extends from its rear end very nearly to its bottom or lower surface, the portion of said inner case not so enclosed being intended more particularly as a water-chamber.

F "shows a door, hinged to the rear end of the case A, so that it may readily be'opened or closed, as hereinafter set forth and G is' a connecting-rod, connecting said door with or to a standard, H, the lower end of which is inserted in a wheel, held upon a spindle, free to move in the plates '11, attached directly upon the exterior of the curved plate of metal E.v Upon the lower side of this wheel is secured one end of a curved rod, J, the opposite end of which is secured upon the upper side of a float, K.

This float K is simply a hollow hemispherical body of metal, made sufficiently large to be easily acted upon by .water, as more fully described.

To the forward end of this float is attached one end of a chain, L, the opposite end of which is attached to the rear end of a lever, M, suspended in the ears 0, upon the water-supply pipe 1?; The forward end of this lever M opens or closes the valve Q placed at the rear end of the water-supply pipe P, for the purpose hereinafter described.

It shows a cover, which, that the apparatus may operate efliciently, shouldfii lightly over that portion of the inner case 0 in which the water-chamber is placed; and in the side of this cover, so that communication may be had with the interior, is inserted a pipe, S, the use of which will be hereinafter explained.

The apparatus maybe placed uponthe pipe leading from a heating-apparatus, so that the gases arising from the consumption of the fuel. contained therein may pass into the outer case, and thence around or beneath the inner or secondary case 0, and, having performed their function, shall pass out of or away from the case or box A, through an opening upon the opposite side, through a pipe inserted in'this opening, to the chimney.

7 Having been so positioned, and the water-supply pipe having been connected with a water-tank, or other means to supply water, the cock T is opened, the inner or secondary case supplied with water, which water rises in the water and steam-chambers to the height of the cock T, and the cock is closed.

As the gases arising from the consumption. of fuel in the furnace enter the outer case, they either pass around or beneath the steam-chamber, heating the water in the same, until steam is produced, when the water in said chamber is depressed, and the water in the water-chamber is elevated, and, acting upon the I float, raises the same.

As the float is raised, it, through the curved-rod standard and connection, opens thedoor, admitting a volumeof air into the case or box A, thus checking the draught by the air admitted between the flue and the fire-chamber. As the air enters the box or case A, the exterionof the steam-chamber is cooled, and, as the steam is condensed, the float previously elevated is depressed, and, as it falls, the door connected to the same, as shown, is closed.

When, from any cause, the water contained in the inner or secondary case falls below the water-line, and it becomes necessary to resupply water to the same, the float, in its descent, causes the forward-eud of the leverM to be elevated, opening the valve upon the water-supply pipe, and allowing a suificient quantity of water to enter the inner case or box, and, when this quantity of water is supplied, this valve is closed by the rising of the float to the surface of the same.

Thus, it will be seen, that in the construction of the apparatus, provision is made both for the'opening and closing of the door, and fora supply of water to the same.

While the apparatus is in operation, the evaporation arising from the inner case passes through the pipe S into the furnace, this pipe being continued so as to communicate with the same, and mingles with the hot air supplied to the apartments.

While I have spoken of the steanbohamber as dependent upon the gases arising from the consumption of fuel, I am aware that, in some cases, steam may be supplied to generate steam in the steam-chamber, without changing the nature of myinvention.

This means of generating steam in the steam-chamber may be used by connecting the steam-chamber with a steam-generator.

Having thus described my invention,

What is claimed as new, is-

1, The combination of a steam-chamber, float, and door, connected to the float in any convenient manner,

when the same shall be constructed and operate substantially as and for the purposes set forth.

2. Combining, with the float, the lever operating the valve of the water-supply pipe, substantially as and for the purpose set forth.

ROYAL E. DEANE.
