JOHN A. PRINDLE, OF CLEVELAND, OHIO.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 392,932, dated November 13, 1888.

Application filed August 1, 1888. Serial No. 281,682. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN A. PRINDLE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Radiators; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in sectional radiators in which the nipples for connecting the different sections are divided by internal diaphragms into two longitudinal compartments, the end sections of the nipples below the diaphragm being cut away, leaving the lower passage-way of the nipple in open relation with the chamber of each leg of the radiator-section, while the walls of the nipple above the diaphragm are cut away in part only, so that the upper passageway of the nipple is in open communication with the chamber of only one leg of a radiator-section, to the end that with such construction better circulation is had, and consequently the radiator has better heat-radiating qualities.

In the accompanying drawings, Figures 1 and 2 are respectively side and end elevations of radiator sections detached, portions being broken away to show the construction and to reduce the size of the figures. Fig. 3 is a reduced elevation showing different sections connected. Fig. 4 is a side elevation of nipple.

The radiator-sections shown in Figs. l and 2 consist ofreturn-bends A and A, connected by tubular legs 13; but the sections, if preferred, may be wholly of cast metalfor instance, as shown at the right hand in Fig 3. Each radiator-section has threaded holes a, for connecting the different sections by means of nipples 0. Each nipple has an internal longitudinal partition or diaphragm, a, cast in and extending from end to end of the nipple, such diaphragms, when the nipples are screwed in, extending in the horizontai position shown in Fig. 1. The opposing nipples are intended to meet at the center of a section, as shown in Fig. 2, and the end portions of a nipple that extend inside a radiator-section are cut away for about three-quarters of the circumference thereof, the remaining quarter, 0, commencing at the diaphragm on the one side and extending to about the top of the nipple. The passage-way d, through the nipple above the diaphragm c, is therefore closed as against the chamber in the one leg of the radiatorsection, as shown on the right hand in Fig. 1, while passage-way d is in open relation with the chamber of the other leg of the radiator-section. The passageway d, that extends through the nipple below diaphragm c, is in open relation with the chambers of both legs of the radiator. The steam, on entering the radiator at the induction end thereof, at first, of course, fills both passageways d and d about alike. The heavier steam and condensed water soon gravitate to the lower passage-way, (1, while the drier steam rises to the upper passage-Way, d, and from thence, the dry steam having egress only to the chamber in the one leg of the radiator-section, a current of steam is at once established up through such leg and down through the opposite leg, the condensed water of course gravitating to and flowing along the passage-way d toward the eduction end of the radiator. The result is that an active current of steam or other heating medium is established through the radiator with corresponding radiation of heat.

In case hot water is used in the radiator as a heating medium, it might in some cases be of advantage to connect the upper returnbends by means, for instance, of ordinary nipples, a suitable location for the threaded holes necessary for such purpose being shown in dotted lines at a, Fig. 1.

What I claim is 1. In a sectional radiator, a nipple for connecting the different sections, such nipple having internal diaphragm dividing the nipple into upper and lower passage-ways, the end portions of the nipple being cut away, substantially as shown, leaving the lower passageway of the nipple in open relation with the chambers in both legs of the radiator-section, while the upper passage-way of the nipple connects with the chamber of only one leg of the radiator-section, substantially as set forth.

2. The combination, with radiator-sections,

substantially as indicated, of nipples for connecting the different sections, each nipple having two passage-ways, upper and lower, the lower passage-way connecting with the cham her in each leg of the radiator-section and the upper passage-way connecting only with the chamber in oneleg of the radiator-section, snbstantiztlly as set forth.

In testimony whereofl signthis specification, in the presence of two witnesses, this 6th day :0 of J uly, 1888.
