IMPROVED HOT-WATER HEATING APPARATUS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, HENRY'HOWARD, of Springfield, Hampden county, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Hot-WaterI-Ieating Apparatus; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. In the drawings-.

Figure is a front view.

H Figure 2, avertical section and Figure 3, a plan view of my improved apparatus.

My invention consists in a new and improved arrangement of boilers and radiators, and certain means for regulating the heat from the same,

I will first describe the construction of'my heating apparatus and afterwards my regulating arrangements- I place, one above another, a number of boilers, so constructed that a large interior surface is exposed to the file, they being tubular and generally in the form of a parallelogram, but having tubular bars entending across from side to side, so arrangedasto make flues for the flame and heated air to draw through. On'the outside of this parallelogram are arranged the radiators, which are of a peduliar form, as will be hereafter described. I arrange these boilers in a brick case, A, enclosing them, forming a chamber, leaving space for the radiators on all sides except the front. Underneath these boilers I place the fire-grate, B. C O C O are the tubular bars extending across from side to side of the boilers; and at D I place a damper, so arranged as when opened to allow the flame and heated air to pass directly up into the chimney through the opening, as indicated by the red arrows; but when shut, as is shown in black lines, passes down the flue E, and around up through thejlue F', as shown by the black arrows.. When the damper is to be moved it is operated by a. handle, G. Besides the regulation of this damper, D, I have another method used in connection with it formore fully regulating the draught. This consists of the two doors or dampers H K, the one, H, opening into fire-grate B, and admitting air up through the. fire, thus increasing the heat by thedraught, and the other, K, opening underneath the chimney, so as to allow the cold air to draw directly up into the chimney, thus decreasing the draught and consequently the heat. To accomplish a perfect regulation of the heat by means of these doors, I connect them with either end of a lever, L, which is pivoted to thefront wall of the chamber. In order to operate this lever and close one door, opening the other at the same time, I attach to one end of the lever a hollow globe, M, which is balanced by weights on the other end. To this globe I attach an elastic pipe, 1 which is also attached,

, to one of the boilers, so that Wvhen suflicient steam is generated to form the requisite pressure Water is forced up this elastic pipe, P, into therglobe M. In this case the globe becomes heavier, Weighing down that end of. the lever, closingthe door H, and opening, by therise of the otherend of the lever in the same operation, the other door, K. By these means a perfect regulation of the draught is obtained. I form the radiators in a peculiar manner, as is shown in the drawings, at 3, having the tubular part B. larger than the tubular part S,

and having a partition placed centrally anddongitudlnally in the mouth of the radiator, where it is attached to the boiler, as shown by the dotted lines. In this device tlie water in the part S, having proportionally to its bulk a larger surface exposed to'tne action of the air, becomes consequently cooled faster than the water in the:

part B, and by these means increases the circulation through the radiator. It Will be seen that my improvements are equally adaptable to steam boilers and heaters as to the hot-Water heater described, and the advantages I obtain are perfect regulation of the ,heat and by adding to or decreasing the number of boilers, I also adapt this apparatus to the heating of large or small houses; and, at the same time it is more easily packed and transported,.while a large surface is obtained forftho. radiators, and also large interior surface exposed to the heat of the fire.

New, having described my. invention, what I claim as new, and desire to secure by Letters Patent, is- 1. The arrangement of a number of boilers one above another in such a manner as to form fines by their sides, and having tubular bars connecting them, substantially in the manner and for the purpose set; forth.

2. The combination with a boiler, by means of a flexible pipe, of a. hollow vessel, arranged and operating for the purpose of regulating the fire, substantially as described. w

3. The radiators, formed as described. having one part, B. larger than the other part, S,substantially as Wm set forth. HENRY HOWARD.
