SPEGIFICATION forming part of Letters Patent No. 777,289, dated December 13, 1904.

specification.
This invention relates to radiators for heating purposes constructed. of sheet metal, and more particularly to that class of radiators comprising one or more units builtup of inner and outer tubular members having their ends joined together in such a manner as to leave a space between them for the reception of the heat-conveying medium and a central vertical open flue through which air may rise in contact with the walls to increase the heating capacity.
One feature of my present invention relates to the means for establishing communication between adjacent units, for connecting or tying them together, and for maintaining their alinement by preventing their relative displacement in a direction transverse to that in which they are tied. together. This feature of my invention is devised with the general object in View of improving the structure of the radiator, of cconomizing in the cost of its production, of simplifying the construction, and of reducing the number of accessory parts.
My invention will be fully understood by reference to the accompanying drawings, in which Figure 1 is a front elevation of a radiator constructed of live units. Fig. 2 is a vertical sectional view of an end unit of the radiator and a portion of an adjacent unit connected therewith. Fig. 3 is a side View of one end of a unit illustrating one member of a joint used to connect the opposed walls of adjacent units in the radiator.
A represents the outer member, and B the innermcmber, of a double-walled tubular radiator, and O is the central air-flue thereof.
D represents the means for connecting the pipe through which the heating medium is conducted to and from the radiator.
E is the circulating-passage extending across the air-ii ue between opposite points in the walls of the inner member.
F is the connection by which the opposed walls of adjacent units are tied together in building up the radiator and through which circulation is established among the several units.
Or is a blind connection employed between the upper ends of the opposed walls of adjacent units, by which when suitably soldered the units may be additionally tied together and by which relative displacement of the units in a direction transverse to that in which they are tied together is prevented.
.The pipe connection D comprises a projecting flange 1, struck up from the metal of the outer member A, and a thimble 2, having a peri iheral groove into which the outer edge is upset to form a locking-lip 3, as shown in Fig. 2. The thimble 2 is internally threaded, as at l, to receive the conducting-pipe. After these parts are thus assembled they are dipped in a soldering-bath, which securely unites the thimble with the metal of the member A, making an air and steam tight connection and preventing the thimble 2 from rotating in the radiator when the pipe is screwed into it.
The connection E is constructed by striking up the metal at opposite points in the walls of the inner member B, so as to form bosses 5 with straight inturned flanges 6. The inner portions of these flanges are jointly formed into a roll 7 the metal of the respective flanges being in contact throughout the roll. This particular form of joint forms a connection in which there is no tendency of the contacting walls to separate under internal pressure of the heat-conveying medium; but, on the contrary, the walls are so formed that internal pressure forces them into intimate contact and preserves the joint. This effect is favored by the fact that the flanges are rolled together and then extended radially,
so as to provide for the abutment of the edges of these flanges against the horizontal cylindrical portion of the bosses 5, which sustain the inner flange against the pressure of the outer flange. In practice this joint maybe dipped into a soldering-bath to hermetically close It and prevent the heating medium entering between contacting parts under internal pressure of the radiator.
The connections F and G are constructed with three objects in common namely, providing a joint that may be effectively soldered for tying together the radiator units, accurately alining these units when they are as sembled, and holding the units against lateral displacement when in use. The connection F, which difiiers from connection G in that it establishes a circulating-passage between units, is constructed with the further objects of additionally tying the parts together by a locking-lip and securing more complete drainage between units by reducing the height of the circulating-passage above the bottom of the radiator. The connection G is formed by striking up bosses at corresponding points in the opposed walls of the units, which bosses are constructed with the upper sharp inclines 8, the lower inclines 9 extending from the lowest points in the radiator units in a slightly upwardly inclined position, an annular portion 10 in a plane transverse to the axis of the opening, and the concavo convex lips 11 and 12 fitting the one into the other and tied together by locking-lip 13, carried by one of said parts and upset over the other. The contacting parts of this joint are further intimately united after the parts are assembled by dipping the joint in a soldering-bath. The opening through the connection F is eccentric to the base of the struck-up bosses 8 9, with the result that the passage F is brought very low down toward the bottom of the radiator and the drainage or circulation is greatly improved-that is to say, there is very much less space below the bottom of the passage F in which to trap the cooler portion of the heating medium than has heretofore been encountered in sheet-metal radiators having connecting means struck up from the outer walls of the units.
The connection Gr is similar to the connection F, employing the bosses 8 with the radial walls 10 and the concavo-convex bosses 11 and 12, except that the latter instead of being perforated and united by the locking-lip 13 are closed. This connection 9 primarily sustains the units of the radiator against displacement transversely to the direction in which they are tied together by the connection F while the parts are being assembled,
and it also serves to assist in tying the units together when dipped into a suitable soldering-bath which unites the contiguous wall of the connection.
Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
1. In a sheet-metal radiator, means forming a connection between adjacent units consisting of the concavo-convex bosses struck up from the walls of the respective units formed with abutting faces and fitting one over the other.
2. In a sheet-metal radiator, means forming a connection between adjacent units consisting of the concavo-convex bosses struck up from the walls of the respective units formed with abutting faces and fitting one over the other and soldered together.
3. In a sheet-metal radiator, means forming a connection between opposed walls comprising the inclined bosses struck up from said walls, formed with straight annular abutting portions, and with concavo-convex portions fitting one over the other.
4:. In a sheet-metal radiator, means forming a connection between opposed walls comprising the inclined bosses struck up from said walls, formed with straight annular abutting portions, and with concavo-convex portions fitting one over the other; said concavo-convex portions being provided with openings and being tied together by upsetting the edge of one over the edge of the other.
5. A sheet-metal radiator comprising a plurality of units tied together at one end and fitted together at the opposite end by means of concavo-con vex portions struck up from the walls of the units and fitting one over the other.
6. In a sheet-metal radiator, a closed connection for the units thereof comprising abutting bosses struck up from opposed faces of the units constructed to interlock to hold the parts against displacement.
7. A closed connection for sheet-metal radiators comprising bosses struck up from opposed faces of the units, formed with abutting portions, and closed interlocking portions circumferentially within the abutting portions.
The foregoing specification signed this 30 th day of June, 1903.
