STEAM-HE'ATING' APPARATUS.

SPECIFICATION forming part bf Letters Patent No. 781,467, dated. January 31, 1905. Application filed July 26,1904. Serial No. 218,201.

To all whom, it may concern.

Be it known that I, VVILFRED SHURTLEFF, a

citizen of the United States, residing at Moline, in the county of Rock Island and State and operation of partsare as hereinafter described, reference being had to the accompanying drawings, in which 1 f Figure 1 is a sectional elevation-of a portion of a building in which my improved apparatu's is shown arranged. Fig. 2 is an enlarged view, part being broken away, illustrating the details of construction and arrangement of the regulator. Fig. 3 is an enlarged section of a pipe connected with the condensing-radiator and provided with a check-valve. Figs. 4: and 5 are horizontal and vertical sections illustrating the construction of the heatradiators and their arrangement relative to the wall of a room.

Referring in the first instance especially to Fig. 1, A indicates a boiler, which maybe of any preferred construction, the same being connected with the chimney D by pipe at and provided with a water-gage a. B and B indicate heat radiators located in different rooms or apartments of a building and connected by a pipe F with the steam-space of the boiler A. Each. of the radiators is provided with a valve operated by hand-lever 6 for the purpose of regulating admission of steam, as may be required by the conditions of the respective apartments. The radiators are connected by a return-pipe G with the water-feed pipe E, which is attached to the lower portion of the boiler A. A condensingradiator O is located in another apartment of the building, and it is connected with the livesteam pipe F by means of a pipe F. The ra diator has a small pipe 0, which connects with the said pipe F and serves to remove water of condensation.

It is further provided with an air-escape pipe -H, leading to the chimney D, and in saidpipe is arranged a check-valve it, as shown in Figs. 1 and 3. This valve is constructed in a well known manner and hinged so that it opens to slight pressure. It seats backward, as shown, so that air is prevented fromaccess to the pipe H from chimney D.

\ The apparatus, which in view ofits function I term the regulator, is illustrated in Fig. 1, but more plainly in Fig. 2. A spherical water-holding vessel I is supported at the end of the longer arm of a horizontal lever J,

the same being fulcrumed at f in a hanger K with a rigid or fixed'pipe M, which in turn connects with the feed-pipe E, as shown in Fig. 1. The upper side of the Water-holder I is in the same way connected by a flexible pipe N with the steam-pipe F. The latter is also provided with a valve 0, the same having a lever P, which is weighted at one end and jointed at the opposite end to a sleeve Q, that slides upon a vertical rod R, which is pivoted at r to the lever J and also at its lower end to the arm 8 of the damper S, arranged in the boiler escape-pipe a. It is apparent that the aforesaid rod R will rise and fall vertically, corresponding to the vertical oscillation of the water-holder I and its lever J The valve 0 is normally closed, and the sleeve Q has a certain degree of free sliding movement on the rod R, it being arranged between a head r and collar 1".

From the foregoing description the operation of the regulator in connection with the other parts of the entire apparatus will now be understood.

It will be understood that the water-holder I'is ordinarily counterbalanced by weight L, so as to allow one pound pressure in the boiler A. Steam generated in the boiler A passes by pipe F to the heat-radiators B B, its admission to the latter being regulated by cocks or hand-valves b, as required. The radiators are of such size that practically all the steam is condensed in cold weather, so that when there is one pound pressure in the boiler there is no pressure in radiators B B or the return-pipe G, the water of condensation returning in pipes G E to the boiler A by gravity. In case of the production ot'fsurplus steam or steam beyond a certain predetermined amount one pound pressureit is drawn oli into the condensingradiator (J, when its condensation produces a vacuum. The normal water-level in the boiler A is indicated by dotted line :10, Fig. 1, and the horizontal median line 9 indicates the height to which water is raised by one pound pressure of steam in the boiler above the normal atmospheric pressure, and it is obvious the radiator G will be entirely empty until such pressure is reached. In other words, such pressure causes water to rise in feed-pipe E, whence it flows through pipes M M into holder I. The weight of water thus accumulated in holder I causes the latter to descend a short distance, which movement carries down the fulcrum of the rod R, so that the boiler-damper S is nearly closed, the steam-valve 0 remaining fixed in position by reason of the sleeve Q of valve-leverPsliding on the said rod R. If now the heat in the fire-box causes generation of steam beyond one pound, it is obvious the water column will rise still higher in pipes E and G, and consequently in the holder or vessel I also, and the latter being thus weighted to a further degree it descends farther than before, and consequently closes or nearly closes the damper S, so that the draft in the fire-box and the generation of steam are lessened, while the steam-valve O is opened at the same time by reason of the contact of the head 1 of the descending rod R with the sleeve Q of the valve-lever P. This of course allows surplus steam to escape into the radiator C, where it is condensed and serves as a means for heating the room in which said radiator is located. The water of condensation returns to the boiler by pipes c, F, E, and. E. The air accumulated in the heat-radiators B B and return-pipe G is drawn oli at the same time and passes from radiator G through pipe H to the chimney D, a return current being prevented by check-valve h. The boiler, pipe F, and radiators B B having been thus relieved of surplus steam and the fire dampened, the normal status is restored, the water flowing back from holder I through pipes M M into the feed-pipe E and boiler A.

It is apparent the operation above described will be repeated intermittently so often as the steam-pressure exceeds the pressure for which the regulator is set.

The preferred construction of the heat-radiators B and B is shown in Figs. 4 and 5, and the latter illustrates the arrangement of the same in recesses in the adjacent wall X. In other words, the radiators are placed near the floor along the Wall, and thus occupy the place of the ordinary base-board, whereby space is economized and a decorative ell'eet obtained.

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

1. The combination, with a steam-generator, a heat-radiator and a pipe connecting the two, of a condensing-radiator and an interposed regulator comprising a movable watm holder connectedwith the boiler, a valve in the steampipe extending to said condenser, and a damper in the boiler-flue, both said valve and damper being operatively connected with said water-holder, substantially as described.

2. The combination, with a steam-gelaerater, heat-radiators and a connecting-pipe, of a condensing-radiator and a means for regulating the escape of surplus steam to such condensing-radiator, the same comprising a movable water-holder connected with the water-space of the boiler, a valve in the pipe connecting the steam-space ol the boiler with the condensing-radiator, and means operatively connecting such valve with the said water-lmlder, whereby the vertical movement of the latter,

dependent upon the amount of water forced into it by steam-pressure, operates the said valve automatically, substantially as described.

valve in the pipe which connects the steamspace of the boiler with the condensing-radiator, a damper in the boiler-flue, and a movable device connecting the water-holder with said valve and damper, whereby, when the weight of water forced into the water-holder exceeds the predetermined amount, the waterholder descends and thereby closes the damper and opens the valve for escape of surplus steam, substantially as described.

4. The combination with a boiler, heatradiato rs, a pipe connectingthem with the boiler, and a condensing-radiator, of a regulator comprising a water-holder which is movable vertically and counterbalanced and provided with pipes that connect it with the water-space of the boiler, and the said condensing-riuliator, a valve in the steam-escape pipe leading to the condensing-radiator, and means operatively connecting such valve with the water-holder whose movement controls it, substantially as described.

5. The combination, with the steam-generator, a heat-rzuliator, a pipe connecting them, and a valve located in the steam-escape pipe forming part of the live-steam pipe, of a wa terholder attached to a lever, which is pivoted and counterbalanced, a flexible pipe connecting the lower side of the water-holder with the boiler feedpipe, and another flexible pipe connecting the upper side of the water-holder withthe steam-escape pipe, a Valve located in the steam-escape between the boiler and the flexible connection, and means which operatively connect the water-holder with said valve, whereby, when the water-holder de-J scends below a predetermined point, the valve is open to allow escape of surplus steam, sub stantially as described. I v j 6. The combination, with a steam-generator and a steam-pipe connected therewith and having a valve for regulating escape of steam, of a water-holder connected on one side withsaid pipe and on the other with the water-space of the boiler, the said water-holder being" vertically movable, of a rod which is pivotally attached to the water-holder and provided with a head and collar as described, the valve having an arm provided with a sleeve adapted to slide on the rod between saidhead and collar, whereby a certain movement of the waterholder may occur without disturbing the valve and a greater downward movement opens the valve, substantially as described.
