RECElVERvFOR VAPOR HEATING SYSTEMS.

Specification of Letters Patent.

Patented Feb. 12, 1907.

Application filed May 26,1906. Serial No. 318,858.

To LZ whom, t Nanny concern:

pipe E, which leads to the' chimney, as in the Be it known that I, ALBERT P. BRooMELL, i patent above referred to.

the receiver; to provide the lever of the relief-J valve with an adjustable rod which may be set to be engaged by the ball, so as to open the relief-valve at any desired pressure; to counterweight the ball at its bottom to keep its chain connection uppermost, and, finally, to cause any water from the relief-valve to overflow into the receiver, whence it will return to the boiler. These objects I accomplish by the construction shown in the drawings, in which- Figure l is a plan of my impro ved vaporreceiver. Fig. 1. Fig. 3 is a section on line 3 3 of Fig. l.. Fig. 4 is a detail perspective ofthe elbowcoupling of the safety-valve.

B designates the receiver in the form of an upright cylinder, having an open upper end upon which rests a centrally-apertured concave frame or spider b, having a lug b, entering a recess b2 in the upper edge of the receiver to prevent the spider from turning, The lower contracted end of the receiver is provided with a pipe B for connection with the boiler at a point below the water-line for the return of the water of condensation or overflow from the safety-valve.

A is a chamber farmed at the upper end of the receiver and provided with the depending partition c, which terminates above the bottom of the chamber to cause the formation of a water seal. In the side of the chamber outside of the partition c is tapped the return-pipe D for the water of condensation from the radiators, while into the top of this portion of the chamber is tapped the venti slight pressure in the Eig. 2 is a section on line 2 2 of' end of the rod passes F is the open top water-gage, in which the water stands at a level, depending upon the I boiler, just as in the aforesaid patent. i G designates a suitable oat in the ref ceiver, carrying a chain g, extending up ,l through the guide-frame or spider b and i thence to the furnace door or damper, (not i shown,) as in the patent referred to. Within i the bottom of the float is a weight which ,l keeps the eye to which chain g is connected l always at the top.

On one side of the receiver is formed a rel lief-valve chamber H, opening into the receiver, this chamber being open at its top and bottoni and formed with a lateral offset of the safety-valve lever t by means of a extends into the receiver above the float G, where it is provided with a slot i6. Extending through the slot i is a vertically-adjustable rod G, provided with a series of apertures g2, through any one of which and the slotted end of the lever is passed a split key or pin g3. The lower end. of the valve-actuating rod G is provided with an abutment or arm g5 in the form of a ring which lies in the upward path of the ball-float G and affords a good contact-surface, and the upper through a slot b3 in one l split key i5, the opposite end of which lever y Aarm of the spider t.

The relief-valve I seats upon the upper end of an elbow-coupling I', which enters the lower open side of the chamber H, to which it l is clamped bv bolts h 7L, extending through apertured ears c" on elbow I and apertures in the flange h of chamber I-I. The opposite end of the coupling or connection I/ connects with the vapor or steam space of the boiler, as in the patent referred to. In the present construction, however, should the boiler blow off water instead of steam the water will simply run into the receiver and back into the boiler instead of overfiowing into the room in which the furnace is situated.

The stem of the valve I is slotted for the passage of the valve-actuating lever i, and to the reduced upper end of the valve-stem is IOO stated as follows:

ing a socket receiving the said reduced end, the two being .secured together by a transverse pin t3. By pulling out the lever t', which is readilT removable, the valve may be rotated and ground to its seat.

The ball works through the op en upper end of the chamber IVI and in practice is made of some less expensive material than the valve itself, the latter being of brass, while the ball is of cast-iron.

The valve is not actuated by steam-pressure in the boiler, but is opened only b v the rise of the float.

The operation is substantially the same as in the aforesaid patent and may be brieliyi All of the return-pipes from the radiators lead to the chamber C, where the air is trapped and conducted to the chimney or other flue. When any pressure exists in the boiler, the water will of course rise in the receiver until it balances the pressure in the boiler, and the rising of the float will cause the closing of the damper and usually prevent increase of pressure in the boiler. Should the pressure in the boiler increase, however, the float will continue to rise and will raise the lever and cause it to open the relief-valve I, and should water blow off it will, as before described, not overflow into the room, but will run into the receiver B. If it is desired to open the reliefvalve at a very low pressure, the rod g is lowered near to the ball-float, and where higher pressure is desired the rod will be raised the desired extent.

I do not restrict myself to the particular construction of parts shown, as the same may be varied without departing from the spirit of my' invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is#

l. In a steam-heating apparatus, a receiver for the water of condensation from the radiators, a connection at the upper end of the receiver for the return water, a connection at the lower end of the receiver for returning the water to the boiler, a damper-actuating float in the receiver, a relief-valve chamber at one side of and opening into the upper end of the receiver, and having a connection for the steam-space of the boiler, a relief-valve in the said chamber, and a lever for lifting the valve extending into the receiver for operation by said float.
