STEAM-RADIATOR.

SPEGIFICATlION forming part of Letters Patent No. 231,722, dated August 31, 1880.

Application filed December 22, 1879.

To all whom it may concern:

Be it known that I, THADDEUS O. J or, of

Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and Improved Steam Heater or Radiator; and I do hereby declare that thefollowin g is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, formin g part of this specification, in which- Figure 1 is a top view of a radiator or heater consisting of a single segment of hollow heatdistributing wings or projections, a steam-receiving chamber, an air-valve, and inlet and outlet valves, the same being constructed in accordance with my invention. Fig. 2 is a back view of the same. Fig. 3 is a vertical radial section of the same in the line 00 a: of

Fig. 1, and Fig. 4 is a vertical transverse section of the same in the line y y of Fig. 1. Fig. 5 is a top view of my improved radiator as shown in Fig. 1, but consisting of two segments similar to that shown in Fig. 1. Fig. 6 is a front view of the plan of segmental radiator shown in Fig. 1, but showing three segments, one arranged vertically upon another; and Fig. 7 is a vertical section of the pile of segmental radiators shown in Fig. 6, the section being in line 3 y of Fig. 5.

The nature of my invention consists, first, in a steam-receiving and condensed-water-discharging chamber formed with hollow closed extensions which are in communication with its interior and present broad tapering sides internally and externally, and are gradually widened from their inner to their outer ends in both horizontal and vertical planes, as presently described, whereby a very compact radiator with very great heating capacity is produced at comparatively small cost, and the appearance of which is very tasteful; second, in a radiator or heater having its inlet-valve for steam and its outlet-valve for condensed water coupled together by a novel combination of devices, whereby the opening of the two valves and the closing of the same simultaneously are effected by the one means, and thus the opening of either of the said valves or the closing of the same without opening or closing its fellow valve is rendered impossible and serious accidents are avoided; third, in the combination of two or more segmental ra diators arranged on the same horizontalplane and not in communication with one another, and two or more segmental radiators arranged on the same horizontal plane with one another, but on a different horizontal plane from the first series of radiators, the respective piles of segmental radiators not being in communication withone another, and the wings of one radiator extending between the wings of another, as will be hereinafter explained; fourth, in the segmental radiators provided with peculiar means for forming the joint connections and securing the radiators together, as will be hereinafter explained; fifth, in a novel combination and arrangement of two or more series of segmental radiators, the radiators of each series consisting, respectively, of a steam-receiving chamber and extension wings which are hollow, the radiators of each series communicating with one another, the hollow Wings of one radiator projecting between the wings of another radiator, as will be hereinafter explained; sixth, in a radiator comprising a series of horizontal segments each of which has a steam-chamber and hollow radiating wings, and is provided with its independent steaminlet pipe and valve and outlet pipe and valve and air-escape valve, as will be hereinafter explained.

A in the accompanying drawings represents one segmental heater or radiator constructed in accordance with my invention. The chamber a, into which the steam is first conducted, is formed of two segmental plates, 00, set vertically, two horizontal segmental plates, d 01, forming the bottom and top, and two radial end plates, 0 c. It may be in separate pieces or it may be cast all in one piece. In the bottom plate, d, inlet and outlet pipe collars b bare provided, and upon these collars respect ivcly are applied pipes for admitting steam and conveying away the water of condensation. On the upper ends of the collars b b flaring valve-seats are formed, and in the top plate, (1/, stuffing-boxes f f are fitted by being connected to hollow collars g g, and through these stuffing-boxes valve-rods h h are passed downward and their lower ends made to fitinto and close the inlet and outlet valve passages.

Both of the valve-rods h h are connected together by a strap-plate, t, which acts similarly to a bow-spring when the valves on the rods are to be opened by it, and as a rigid bar when the valves are to be closed by it. The strap-plate i is passed under a stand, j,-and is acted upon by a thumb set-screw, 7a, which is fitted to work up and down in a nut, is, of the stand. The lower end of the screw is coupled by a shoulder and collar to the strap-plate, and by this means the plateis raised and lowered by the screw. By turning the screw to the right both valves are closed at the same time, and by turning the screw to the left both valves are opened simultaneously, Thus itis impossible to open one valve or close one valt e independently of its fellow valve. The spring action of the strap-plateinsuresasudden opening of both valves when the pressure of the screw is released sufficiently. However, the screw and strap-plate are mainly depended upon for opening the valves.

From the outer segmental plate, 0, hollow extensions 1 are provided. These extensions communicate with the chamber a, and they are radial with reference to the center of the segmental plates 0 c, as shown. The bottom lines of the extensions 1 are horizontal, while the top lines are oblique or inclined in an up- Ward direction from the top plate, d, of the chamber a to the termini of the extensions. The top surface, as well as the bottom, of the extensions presents the form of a very acute angle, while the cross-section of each extension is in either a lozenge or diamond or other analogous form. Theinner ends of the extensions are rectangular in shape, while their outer ends are in form of a diamond; and said ends may be made with a proper bulge or convexcurved form. At the middle of the inner'segmental plate, 0, bolting-flanges m are formed on the back edges of the horizontal top and bottom plates, d cl, through which bolts 0 for coupling several segmental sections together are passed when the heater is formed of several segmental sections piled one upon another.

When'the heater is formed of several segmental sections, as in Fig. 6, those sections which are on a lower plane than the top section are provided with short flanged joint collars n, with joint-stems n, the stems fitting steam-tight into holes a formed in the bottom plates, d, of the respective sections, and if necessary packing'rin gs may be placed around the stems upon the collars. The screw-bolts 0, which pass through the flanges, are provided With heads on one of their ends, and nuts 0 on their other ends, and by screwing up the nuts the sections are bound together, and the joints at a a n which form the communications between the several sections, or allow the steam to circulate throughout the several sections, are made steam-tight.

When a heater or radiator is formed of segmental sections placed against one another, either singly, as in Fig. 5, or in piles of three, more or less, as shown in Fig. 6, the plan view of the heater will be a half-circle, and by adding another segmental heater or a pile of segmental heaters the plan view will be a threequarter circle, and by adding another segmental heater or a pile of segmental heaters the plan view will be a complete circle in general design.

The valve-rods with conical valves on their ends will be the same in construction and operation for a pile of segmental heaters as they are for a single segmental heater, except that the rods are required to be made long enough to extend from the top heater to the bottom one.

When the heaters are piled one upon another the wings of one heater occupy a position opposite the spaces between the wings of another heater, and those portions of the hollow extensions or wings of one heater which rise upward 011 an oblique line from the top plate of the steam receiving and distributing chamber a extend up between the wings of another heater in the manner illustrated in the drawings, Fig. 6. By this means the heater can be made with a large amount of heating-surface, and yet not be of great height.

The form of the extensions or hollow wings I is such that the air to be heated rising between them is caused to pass first through passages which gradually decrease in width, and then through passages which gradually increase in width, and then in passages which, 9

in like manner, decrease and increase in width, and so on until it escapes at the top of the pile of radiators or heaters.

The peculiar ,form and arrangement of the extensions or wings are such that the air-spaces are divided in such a manner that intersecting diagonal circulation-ways are formed, as will be seen by referring to Fig. 6 of the drawin gs, and by this means the air is more exposed to the surfaces heated by the steam in its course through the pile of radiators.

In carrying out my invention on a large scale the form of the wings or extensions Z, and also of the steam-chamber a, as described, will be found the most effective and desirable; but I do not confine myself to the precise form and arrangement shown, as these may be changed in various equivalent ways without departing from the invention which is shown and described.

The advantage of the segmental form shown in Fig. 1 is that it will stand diagonally across a corner of a room and leave an air-space behind it, between itself and the wall. The same benefit of an air-circulation space between the heater and the wall is secured when the heaters are arranged against the side of a Wall in a half-circle, and when the heaters are arranged to form a complete circle an air-circulation space is formed centrally of the pile of heaters or radiators.

Each segmental heater has its own supply and escape pipe and air-valve 19, and each segmental pile of heaters has its own supply and escape pipe, as well as an air-valve.

The air-valve 19 consists of a long rod with a conical valve end, 19', and with a thumb-button, 19 The valve end is inserted through a stuffing-box, q, of one of the extensions or wings I,

IIO

and is forced up to a flaring seat, q, of the steam-chamber, said seat having an air vent or passage through it, as shown in the drawings. When the valve 1) is adjusted for operation the vent of the seat q is open, and when steam is introduced into the heater or radiator the air is allowed to escape, and this having been accomplished, the heat of the steam causes the rod to expand or become lengthened enough to close the air-vent and thereby prevent the escape of steam. When the steam is cut off from the heater the valve cools down and becomes shortened by contraction, and thereby again opens the air-vent to the same extent as when the rod was first adjusted.

111 operating with the radiators steam maybe supplied to one, two, or more piles of segments, according to the quantity of heat required, as each pile will be provided with its own let-on and shut-off cock from the main steam-supply pipe.

What I claim as my invention is- 1. The segmental radiator comprisingin its construction the steam-receiving chamber a, with the hollow radiating extensions or wings I, which are in communication with the interior of said chamber, and said radiator being provided with inlet and outlet valves, and otherwise constructed and operating substantially as herein described.

2. The combination of the radiator A, having hollow Win gs Zin communication with its steamreceiving chamber a, valve-rods h h, valves of the rods, strap 2', standard j, and screw 70, substantially in the manner and for the purpose described.

4. The segmental radiators provided with the means for forming the joint-connections and securingthe radiators together,said means consisting of the parts a n n and m 0, and employed as shown and described.

5. The combination of two or more series of segmental radiators arranged on different horizontal planes, the radiators of each series consist-ing, respectively, of a steam receiving chamber and extension-wings which are hollow, the radiators of each series communicating with one another, the hollow radiating wings of one radiator projecting between the wings of another radiator, all as herein described and shown.
