DEVICE FOR HEATING BUILDINGS.

SPECIFCATION' forming part of Letters Patent No. 427,634, dated May 13, 1890.

Application led January 31, 1889. Serial No. 298,248. (No model.)

T0 MZ rif/'wm it may concern/i Be it known that I, JOHN E. STUART, of Newark, in the county of \Vayne and State of New York, have invented a new and useful Improvement in Devices 'for Heating Buildings, which improvement is fully set fort-h in the following specification, and shown in the accompanying drawings.

My invention relates to heating buildings by means of radiators iilled with steam or hot water; and the object ot the invention is to overcome certain difficulties attending the use of these devices and this means of heating'.

The invention is hereinafter fully described, and the features of novelty particularly point ed out in the claims.

Referring to the drawings, Figure l is a vertical section of a building, showing my improved device for heating attached; Fig. 2, a plan view of some of the parts seen, as indicated by arrow c in Fig. l; and Eig. 3, a general view, on a smaller scale, of a series of rooms, serving to illustrate the advantages of the invention.

Referring to the parts, A are the walls of a building or inclosure of any kind; B, the floor; O O, apartments of various stories, and D the boiler-room in the basement.

E is a steam-boiler of any suitable kind or pattern, and F an adjacent hot-water chamber on a level with the boiler, and connected with the latter at the top by a steam-pipe a and near the bottom by a water-pipe Z1.

G isa pump of any kind-for instance, a steam-pump-conneeted with the hot-water chamber by a water-pipe c and with the boiler by a branch water-pipe d. The pump is connected with the steam-space of the boiler by a steam-pipe e., extending from the steanrpipe a. These pipes described are provided, respectively, with gates f, g, 71., i, and k.

Z is an outiow-pipe leading from the pump to the various radiators H, located in the apartments of the building.

n is a corresponding return-pipe leading from the radiators to the \\-ate1'clia1nber F. `Steam passing from the boiler' to the chamber through the pipe d above the water-line heats the water in the chamber, and the pipe l), joining the boiler and chamber at points 7L the water may be drawn wholly .from the boiler. By this means either hot or warm water may be forced through the radiators, according to whether the weather is cold or moderate, or as it may be desired. The cool wat-er from the radiators iiowing back into the chamber reduces the temperature of 'the water contained therein, and if the gates f and g of the steam and water pipes, respectively, are closed or nearly closed the water in the chamber may be reduced to any degree of coldness down to the temperature of the surrounding air. This enables the operator to perfectly regulate the heat of the apartments.

It frequently occurs in practical house-heating that the iioors of adjacent parts of a building, or of adjacent buildings to be heated from the same boiler, are on different levels, as shown, for instance, in Fig. 3. In such cases the steam or water for heating has to be conducted downward and upward to Various levels, and traps or pockets are formed holding dead-water, and a free circulation or flow to some of the radiators is prevented.

By using the device herein shown a steady flow of hot or warm water may be maintained through any or all of the radiators wholly without regard to the matter of the levels at which the radiators are placed, and trapping or pocketing water is wholly prevented. The pump forces the hot water through all the heating-pipes or radiators back to the hotwater chamber, there being a forced circulation through the whole.

This device is adapted equally well for heating' ordinary dwellings, business blocks, hothouses, establishments for evaporating fruit, railway-cars, boats, the.

The radiators maybe constructed so that by IOO closin g a valve o in each the hot water will be shut off therefrom and turned directly through the outow pipe or conduit Z.

What I claim as my invention is- 1. In a device for heating buildings, a steamboiler and a water-chamber separate from the steam-boiler in the same apartment With the boiler, in combination with radiators placed at different levels in the building, a pump to force Water through the radiators to said Waterohamber, pipes for connecting the radiators Wit-h the pump and the Water-Chamber, respectively, pipes connecting the boiler and the Water-chamber, one pipe being above and the other pipe being below the Water-line of the boiler and the chamber, a pipe connecting the pump and Water-chamber, a pipe connecting the pump and Water-space of the steam-boiler, and gates for controlling the two pipes last mentioned, so that Water may be drawn by the pump from either the water-chamber or the boiler, for the purpose set forth.

2. The combinatiomin a device for heating buildings, of a steam-boiler, a separate chamber for holding the Water for the radiators, a pipe connecting the steam-space of the boiler with the space above the Water in the Waterchamber, a pipe connecting the Water-space of the boiler with the water-space of the Waterchamber, radiators for the apartments of the building, a pump to force Water through lthe radiators to the Water-chamber, a pipe connecting the pump with the steam-space of the boiler, a pipe connecting the pump with the Water-space of the boiler, a pipe connecting the pump with the Water-space of the Watercllamber, an outflow pipe connecting the pump With the radiators, and a return-pipe lconnectin g the radiators With the Water-chamber at a point below that at whichl the pump draws Water from the Water-chamber, substantially as described.
