RADIATOR.

APPLICATION FILED SEPT. 2, 1913.

Patented Jan. 11, 1916.

JOSEPH ELGER, OF CHICAGO. ILLINOIS.

RADIATOR.

Application filed september 2, 1913.

To all whom it may concern Be it known that I, JOSEPH ELGER, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Radiators, of which the following is a specification.

This invention relates to radiators and has for its object to provide a new and improved radiator adapted to be used in carrying out the process of circulating hot water described and claimed in my application No. 732,030, filed November 18, 1912.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a sectional view of a radiator embodying the invention; Fig. 2 is an enlarged sectional view of one of the nipples used in the radiator; and Fig. 3 1s asectional view of a nipple similar to that shown in Fig. 2 but provided with screw threads.

Like numerals refer to like parts throughout the several figures.

Referring now to the drawings I have shown a radiator provided with an inlet section 1 and a series of adjacent sections 1, 1", 1, etc. The inlet section 1 is provided with a suitable inlet 2. All the sectionsare connected together at the top so that the water may flow from the inlet section 1 to all of the other sections. This connection may be made in any desired manner as, for example, by means of any of the usual nipples one form of which is shown at 3.

Between the inlet section 1 and the adjacent section 1 at the bottom I provide a nipple 4 which instead of being open has a web 5 extending thereacross, said web provided near its middle with an inlet opening 6. The other sections of the radiator are connected together at the bottom by any of the usual nipples so that there is open communication between them. The radiator is provided at the rear end with an outlet 7.

Specification of Letters Patent.

Serial No. 787,573.

In the use of this radiator the hot water enters the inlet 2 and passes into "the inlet section 1. The stream of hot water is then divided, the main portion passing up the ing through the opening 6 in the obstructing device or nipple i. The smaller portion of hot water in passing through the opening 6 disturbs as it were the equilibrium of-the water in the radiator by causinga variation in pressure at the bottom of. the remaining sections, and the cold water at the top of these sections, due to the disturbing'ofthe balance, drops down by gravity so as to start the circulation thereby permitting the hot water from section 1 easy access at the top to the remaining sections, said hot water flowing across the top and following the cold water down in the remaining sections, said hot water flowing evenly down said sections, the colder water, due to its weight, passing out through the outlet '7 into the discharge pipe and thence back to the boiler.

I have shown in detail a particular construction embodying my invention, but it is, of course, evident that the parts may be varied, and I therefore do not limit myself to the particular construction shown.

I claim:

1. A hot water radiator comprising a plurality of separate sections connected to gether at the top and the bottom, an inlet connected with one of said sections, a hipple between said inlet section and the adjoining section, said nipple provided with a web extending thereacross and provided near its middle with an opening so that as the water enters it is divided into two portions, the main portion passing up the inlet section and an auxiliary portion passing through said nipple.

2. A hot water radiator comprising a plurality of separate sections, connected together at the top and bottom, one of said sections forming an inlet section and con nected near the bottom with a source of hot water supply, an obstructing device between the inlet section and the adjacent section at the bottom, said obstructing device consisting of a part with a small opening near the center thereof, arranged so that as the hot water enters the radiator it is divided into two portions, a small portion passing through said opening, the main portion Patented Jan. 11, 19156..

passing up the inlet section and across the top of the radiator and down the several sections back of said inlet section;

3. A hot water radiator, comprising a plurality of separate sections connected together at the top and bottom, one of said sections forming an inlet section and adapted to be connected with a source of hot water supply, the sections connected together at the top and bottom so as to provide a non-obstructed passageway from one to the other and means in said connection at the bottom, between the inlet section and the adjacent section for obstructing the flow of water from the inlet section to the adjacent section, so as to limit said flow to a comparatively small stream.

4;. A hot Water radiator, comprising a plurality of separate sections connected together at the top and bottom, one of said sections forming an inlet section and adapted to be connected with a source of hot Wa ter supply, the sections connected together at the top and bottom so as to provide a non-obstructed passageway from one to the other and means in said connection at the bottom, between the inlet section and the adjacent section for obstructing the flow of water from the inlet section to the adjacent section, so as to limit said flow to a comparatively small stream, said means comprising a nipple with a circular shell, having a transverse web formed integral therewith, said web provided near its center with an opening extendingtherethrough.

In testimony whereof, I affix my signature in the presence of two witnesses this 26th day of August, 1913.
