IMPROVEMENT IN RADIATORS.

Specification forming part of Letters Patent No. 36,068, dated August 5, 1862.

To all whom it may concern:

Be it known that we, EDWARD Bounnn and JOHN BoURNE, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Radiators; and we do hereby declare that the following is a full, clear, and exact descriptionv thereof, reference being had to the accompanying drawings, which form part of this specification, and to the letters of reference marked thereon.

Our invention relates to an improvementin that class of radiators (used for warming) wherein steam is admitted at a very low temperature between two thin metallic sheets placed one over the other, having their edges securely fastened together, while the body of the sheets are separated just suiicient to allow of a free circulation of steam, which is conducted therein by means of suitable pipes.

The improvement we have made consists in the applicationand use of short tapering tubes or lines (open at both ends) passing transversely through the sheets, and secured therein iu such a manner as that, While they form a the outward pressure of the steam, they are also intended more particularly to act as passages for the atmosphere as it becomes heated at the back of the radiator to escape through to the front, instead of ascending up the wall near which the radiator may be placed, and causes a better distribution ofthe air as it loecomes heated in an apartment it is desirable to warm than can be accomplished by a radiator wherein no openings are provided for the air to pass through.

Another part of our improvement consists in combining with a radiator constructed in the manner as hereinbefore stated vertical steam-pipes passing up and down the back of the radiator, and connected therewith neareach edge, and communicating with the space between the sheets through the openings formed at each point of intersection in the pipes, for the purpose of conducting the steam uniformly and rapidly to each part of the ra diator, and also as a means of stiflening the sheets by acting as braces thereto.

Another part of our invention consists'in the means we employ to make a perfectly steamthey are riveted together. To accomplish this, one of the sheets is made smaller in size than the other, so that the edge of one sheet projects about one-quarter of an inch beyond that of the one to be riveted to it. Between the two We place a strip of gum-packing, and the edge of the largest sheet is then turned or doubled down upon the gum, and the Whole riveted together. This plan of turning one of the sheets over the packing prevents it from being forced out by the operation of riveting, or driven out by the steam when admitted at full pressure to the radiator. To produce an increased stiffness at the edge of the sheets and also give a greater bearing to the rivets, we surround the whole edge with narrow halfround iron on each side, and pass the rivets through this, as a better security to the parts. To enable others skilled in the art to understand and make our invention, we will proceed to describe the accompanying drawings, in which Figure 1 represents a vertical front view of our improved radiator. Fig. 2 shows an inverted back view of the saine. Fig. 3 represents an enlarged transverse section of Fig. l, and shows more fully our improvements. v All the drawings are lettered, and similar letters indicate like parts on all the figures.

To construct a radiator in accordance with our invention, the sheets A being prepared by straightening and cutting to the proper size and shape, a series of holes are punched in each sheet correspondingv in size and place in both. In the holes so punched short conical or funnel-shaped tubes er ilues d d cl d d are inserted in the holes in the front sheet, where they are held from slipping through by a iiange on their outer ends. After all the iiues are inserted in place in the front sheet, a washer, L L, Fig. 3, of the depth it is desirable to have the space between the sheets, is placed over each iiue. The back sheet is now placed in position, the dues projecting far enough through this sheet to receive another washer, K K, Fig. 3, which is placed on the end of the projecting tlues. The fines are now burred or calked down upon the washers, firmly securing the parts together in a manner that forms a perfect steam-tight joint around each flue. The short steam-pipes s s s s s s being of the requisite length, the ends are furnished with a short elbow, n n a n n n. These are secured to the sheets by means of hollow screw-caps N N N N N N passing through the outside row of holes made in each sheet and tting in a female screw in the elbows. The hollow of the screw-caps form a communication between the pipes and the space in the radiator through small openings 7L h h h, Fig. 3, which allows the steam to pass from one part of the radiator to another regardless of the air that it may contain. The `pipes being secured in place, the edges of the sheets are next brought together, and a gum packingtape, w m, Fig. 3, is inserted between them. The projecting edge of the largest sheet is then turned or doubled down to hold the packing in place, as hereinbefore stated. A piece of half-round iron, B B, is placed on each side of the joint and secured thereto by rivets g g, Fig. 3, passing through the parts, binding them together and forming a steam-tight joint of the most substantial kind.

The steam is conveyed to the radiator through the supply-pipe t t, attached to the radiator through one ofthe elbows at the lower corner. rlhis pipe is provided with a stopcock, p, for regulating the quantity of steam to be admitted. The steam being used at such a low pressure, all the water that forms by condensation in the radiator is conveyed back to the generator by the same pipe. On the opposite corner to that Where the supply-pipe connects is an air-key, C, communicating with the interior of the radiator through the small pipe r. This controls the action of the steam by retaining or allowing the air in the radiator to escape.

Having thus described our improvements in radiators, what we claim is- 1. The application and use of short conical or funnel-shaped air tubes or flues d d d d d d, passing transversely through the steam-space between the sheets forming the radiator, in the manner and for the purpose as hereinbefore stated.

2. Combining with a radiator formed of thin metallic sheets a series of steam-pipes, s s s s s s, having openings h h h h, Fig. 3, communicat ing with the space between the sheets for the purpose of conducting the steam rapidly to all parts of the radiator, and also as a means of stiffening the sheets by acting as braces thereto, as herein set forth.
