4 Claims.

This invention relates to an improvement in radiators for heating purposes and has for its object to provide a radiator structure more particularly adapted for single-pipe heating systems and having improved heating efficiency and operation.

It has been determined that a great deal of the inefficiency in heating, and the noises occurrent in single pipe heating systems, is due to the manner in which the steam is directed into the radiators and the course which the steam follows therein. InV a radiator of conventional construction the steam enters the radiator at one end of the same, flowing in a horizontal direction, and upon entering the bottom passage of the radiator, it rises in the various sections of the radiator. The condensation water, dropping down in the various radiator sections, iiows back along the lower horizontal passage where the steam is entering and against the velocity of the steam.l During the heating up of the radiator, this causes water hammer. Water hammer or radiator knocking so common in single pipe radiator systems, is caused by water attempting to flow along a slightly inclined or horizontal plane against the velocityof steam flowing in an opposite direction. The velocity of the steam drives the water against the end of the passage with such force as to create hammer. It is obto provide a passage wherein steam is injected and in which Water will collectand ow, is one wherein hammer and knock is most likely to occur.

The primary object of my invention, therefore, is to provide a radiator so designed that the steam upon enteringthe radiator, is directed upwardly or vertically toward the top of the radiator and is distributed through the top passage thereof, permitting the condensation and steam to descend together in the same direction. With this arrangement, the venting air, steam and condensation do not meet in an opposing ilow until the condensation reaches the steam inlet opening and then it meets the steam only in a vertical owing position so that water hammer does not occur.

A further feature of the invention resides in the venting of air at the bottom of the radiator. By directing the steam to the top of the radiator, it iiows downwardly and forces the air before it in its natural flow. In this manner, the air, steam and water all ilow in the same direction and water hammer and air binding is completely avoided.

In the accompanying drawing, wherein an emvious from this, that a radiator so designed as.

bodiment of the invention is shown, Fig. 1 is a front elevation, with parts in section of the improved radiator; Fig. 2 is a sectional view on the line 2--2 of Fig. l, looking in the direction of the arrows; and Fig. 3 is a sectional view on the line 3 3 of Fig. 1, looking in the direction of the arrows.

In the drawing, 5 and 6 indicate the end sections of the radiator. Each of said sections is providedwith supporting legs 8, upon which the radiator is held in an elevated position above the floor. The end sections are each provided Vwith a closed, relatively flat end wall 1 spaced from an inner wall 9 to provide a vertically disposed iluid passage I0 between them. The passage I0 communicates at its lower end with a boss I I and at its upper end with a boss I2, these two bossesv connecting respectively with the bosses I3 and I4 formed on the adjacent intermediate section I5 of the radiator.` The intermediate section I5 of the radiator is provided with the bosses I3 and I4 connected by the nipples 22 with the bosses I I and I2 on the end section 5.

The intermediate section I5 is provided with a vertically extending, flat iluid passage I6v which communicates with the b osses I3 at its upper end and with the bosses I 4 at its lower end'. At its lower end, the passage IE is formed with an enlarged outlet I1 which connects to the steam inlet pipe I8 in which a'shut-ol valve I9 is located. It will thus be seen that steam entering into the radiator lfrom the pipe I8 will be directed vertically up through the passage I6. Connected to the intermediate radiator section I5 is a plurality of additional intermediate sections 2|) which are similar in construction and shape to the intermediate section I5 except that the lower ends of the passages I6 are closed, as shown at 2| in Fig. 1.

The intermediate sections 20 are provided with the bosses I3 and I4 which connect together by means of the nipples 22 so that the radiator is provided with the continuous, horizontally disposed fluid passages 23 and 24 communicating with the Vertical uid passages Ill and IB in the radiator sections.

The intermediate sections I5 and 20 of the radiator are provided at their front and rear with laterally extending flanges 25, the longitudinal edges of which abut when the sections are placed together so that the radiator presents a relative smooth flat face on its front and rear. The several sections are also provided at their top with anges 26 so that the top also of the radiator is provided with a continuous smooth upper face.

Ill

At the upper portion of the front, and if desirable at the rear or top, the anges 25 on the several radiator sections are recessed as at 21 in Fig. l to provide spaced, abutting lugs 28 which cooperate to form a grille between them. The flanges 25 and 26, and the end walls 'I all cooperate in the formation of a radiator in which the front, back, top and ends are in the form of substantially flat or plane surfaces. These anges and end walls also co-operate to form the vertical lues or air passages clearly shown at 35 in Figs. 2 and 3. As will be there seen, said air passages are located between the several radiator sections, and air entering through the open bottoms of these passages and owing upward through the same, will be heated by contact with the walls of the steam passages I G and emerge from the grille openings 21 at the upper front, top or back of the radiator wherever the grille or grilles are located. To aid in heating the air passing through the passages 35, heat-radiating iins 36 are formed on the walls of the steam passages I6, said fins projecting toward one another in the air passage but not in actual contact.

The intermediate section 29 of the radiator located at the right in Fig. 1 is similar in construction to the section shown at I5 and similar reference numerals have been applied to its parts. The widened opening I'I, in the section 29, receives an air valve 30 which is threaded vertically into the opening I'I.

From the construction described, it will be seen that steam directed through the pipe I8 will be introduced into the radiator in a vertical direction and will reach the top horizontal passage 23 wherein it will be distributed. The condensation and steam will thus ow down together through the several vertical passages I6 to reach the lower horizontal passage 24. With this arrangement, the steam, condensation, and venting air are all moving in the same direction so that water hammerA and noises incidental to the conventional single section type of steam system will be completely avoided.

What I claim is:

1. In a radiator, end sections, a plurality of intermediate sections disposed between and connected to the end sections. an intermediate section situated contiguous to one of the end sections having a heating-huid inlet opening located at its bottom, an. air valve chamber located in the bottom of an intermediate section situated contiguous to the other end section, there being a plurality of intermediate heating sections located between and separating those sections in which the fluid inlet opening and valve chamber are respectively located, theinlet opening being situated in its section at a point located substantially on the vertical center line of said section, the air valve chamber being also located on the vertical center line of its section whereby a substantially equal amount of heating surface is disposed on opposite sides of the vertical center lines of said chamber and opening transversely of the length of the radiator in each of the sections in which the opening and chamber are respectively 1ocated.
