FIREPLACE-HEATER FOR RADIATOR SYSTEMS.

Specification of Letters Patent.

atented Sept. 3, 190'?.

Application filed November 12,1906. Serial No. 843,011.

To all whom it may concern:

Be it known that I, WILLIAM G. CoNKLn, a citizen of the United States, and a resident of Knoxville, in the county of Jefferson and State of Ohio, have invented a new and useful Improvement in Fireplace-Heaters for Radiator Systems, of which the following is a specification.

My invention relates to heating systems of that class in which the available heat from open fireplaces is utilized to heat a circulating body o water which, through suitable pipes, is carried through the various radiators of the house and is then returned again to the heater', so as to secure the advantages of an open fire and at the same time utilize the large amount of heat which usually goes to waste in open replaces. i

My invention consists in the novel construction and arrangement of the fireplace water heater, which I will now proceed to describe with reference to the drawings, in which Figure l is a rear elevation ofmy fireplace heater. Fig. 2 is a transverse horizontal section on line 2'-2 of Fig. l. Fig. 3 is a vertical section taken on line 3 3 of Fig. l. Fig. 4 illustrates details of the packing nuts and Fig. 5 is a vertical section through the chimney and oors of a building, showing the relation and connections of the replace heater to the radiator system.

In Fig. 5 of the drawing are shown two floors of a building with the chimney and fireplace below and two radiators R coupled up with the fireplace water heater X. The hot water supply pipe S and return .water pipe U are both arranged in Athe chimney flue.

The hot water pipe S is tapped into the top of the water heater in the fireplace and is extended in lateral branches through the floors to the inlet sides of the radiators R and the return Water pipe U takes the more or less cooled water from the outlet sides of radiators and returns it into the bottom of the Water heater in the fireplace. An expansion tank T is connected by pipe W with the water circulation pipe U andhas an overflow outlet Y and an inlet pipe S/ at the lower story is connected by a suitable valve with any water supply for the purpose of filling the water heater and radiator system with water.

The water heater in the fireplace is an upright hollow iron shell X made flat and forming the back of the lireplace and held in vertical position by lugs K K, Fig. l, cast on the side edges of the iron back and let into the masonry of the chimney. The hollow iron back extends from the hearth at the bottom of the replace to the offsetting shoulder of masonry Z forming the throat of the chimney lue and this hollow back is so set as to leave a space behind it between the water back and the inner side of the fluo, a seen in Fig. 5.

V is the grate which at the sides is anchored to the l chimney jambs and at the back is supported upon a lip or lugs .l cast upon or attached to the water back.

D, D, D, D, are fiues extending vertically through the heater and passing through the walls of same at the top and bottom. These lues are open at both ends and are held in position by packing nuts E at each end.

The packing nuts are shown i-n detail in Fig. 4, in which P, P, P, P, are holes drilled or cored in the sides of nuts to hold a spanner wrench for tightening or loosening the nuts. The nut is shown threaded at Q..

F, F, Fig. 3, is asbestos or other suitable fireproof packing, held in position by the packing nut, which is intended to hold the flues in position and also to prevent leaking around dues.

In Figs. 2 and 3, G, G, G, are ribs cast with the shell of heater on the inside to prevent buckling and to strengthen the sides of the heater. These ribs not only reinforce the flat sides against warping from the direct contact of the fire, but they give an increased surface exposure to the water inside for more rapidly conveying the heat thereto. These ribs are vertical and arranged between the flue tubes, or alternating with the same.

H2, 2, in Fig. l are holes drilled or cored in the upper and lower ends of the shell and tapped to receive the inlet and outlet pipes S and U.

G, G, are the front and rear walls of the heater and C, C, are the top and bottom walls of the heater, which are made somewhat heavier than the side walls O, C, to permit of the securing of the fines by means of the packing nuts E, E.

A is an. extension of the back oi the shell of the heater at the top, to be built into the chimney in such manner as to act as a baii'ler for the products of combustion and aid in deflecting the same into the top of the flues D.

N is an opening in the projection A, which is fitted with a door M, which acts as a damper to regulate the draft and heat from the fire beneath. M are lugs cast on the rear side of the door and forming part of the hinges for the same. M2 are corresponding lugs on the wall of the heater. The door is fastened by means of the rod passing through the lugs as shown in Fig. l.

M3 is alug cast on the front of door, by means of which, the damper rod M", is fastened to the door. This damper rod extends to the front of the fireplace as p iire in the grate, the damper M at the top is opened makin ga direct draft. Then after the re is Wellstarted the damper M is closed and the heated gases and products of combustion then 'are compelled to dive down through the iiues D and, issuing through the open ends at the bottom, rise behind and in Contact With the shell into the chimney flue where they still impart their heat to the circulation pipes. The water in the shell or Water-back thus becomes thoroughly heated, lirst by the heat from the grate on the iront or outer surlace; secondly, from the heat imparted to the surrounding Water from the ues D and finally from the contact of the hot gases along the back ol the shell as they rise to the chimney place.

This fireplace water heater is of simple construction and therefore cheaply and easily made. It is also adapted to the construction of iireplaces as already built, requiring no destructive cutting oi the masonry and has such an extensive heating surface as to etliciently heat a number ol radiators. Its construction and arrangement is also such as to permit it to be readily coupled up with the circulation pipes, the upright members oi which are all conveniently housed within the chimney, thus avoiding an unsightly appearance in the rooms and at the same time securing the largest absorption and utilization of heat rom the escaping products of combustion.

I claim l. A lire place water heater, consisting; oi a hollow` upright. flat, shell, havingv front and back walls and top and bottom ends, said shell having a vertical upward ex tension o1" the back wall at the top and a vertical do\\'n ward extension of the front wall at the bottom, both said extensions being cast with the shell and formed with open ings, dampers for controlling said openings, and means for operating; them, detachable flue tubes extending; entirely through the shell and through the upper and lower ends thereof, ireprooi packing arranged about the ends ol the tubes and screw nuts arranged about the ends of the tubes to compress the packing and form a water tight joint.

2. A tire place heater, consisting of a hollow, upright. dat, shell having a front and back wall with vertical ribs on the inside and top and bottom ends, said shell havingl` a vertical upward extension of the back wall at the top und a vertical downward extension of the i'ront wall at the bottoni, both said extensions being formed with openings, all of said parts being; cast in one piece. damper-s controlling said openings and means for operating them, und vertical iiue tubes extending through the shell and through the top and bottom ends thereoi at points alternating with the vertical interior ribs of the shell, and a lireprool' packing at the ends ol the tubes.
