RADIATOR.

SPECIFICATION forming part of Letters Patent No. 499,417, dated June 13, 1893.

Application iled August 11, 1890. Serial No. 361,702. (No model.)

To all whom it may concern:

Be it known that I, JOHN DE LANEY, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following isa specification.

This invention relates to that class of radiators which are composed of several independent sections or compartments and ithas the object to construct a radiator in which each section can be supplied either with exhaust steam or live steam, at desire.

In the accompanying drawings consisting 0f two sheetsz-Figure 1 is a longitudinal sectional elevation of my improved radiator arranged in a case or passage through which the air to be heated is propelled by a fan. Fig, 2 is a top plan view thereof, partly in horizontal section. Fig. 3 is a side elevation of the radiator with the casing in transverse section. Fig-4. is a horizontal section, on an enlarged scale, of one of the valves and the adjacent parts ofthe radiator sections between which the valve is arranged. Fig. 5 is an enlarged sectional elevation of one of the valves and its frame. Fig. 6 is an enlarged vfragmentary section of a manifold and one of the heating pipes, showing the coupling whereby the pipe is secured to the manifold.

Like letters of reference refer to like parts in the several figures.

A represents the casing or air passage which incloses the radiator, B the fan case connected with one end of the casing,B the fan and C the exit pipe of the casing through which the heated air is discharged.

D D D2 D3 represent a series of heating sections arranged side by side, within the casing A, and each composed of a base chamber or manifold head e and heating pipes or coils f, through which the steam circulates. The

pipes of each section are preferably bent or curved,-having approximately the form of concentric arches, and secured with both ends in openings in the top plate of the manifold, excepting the innermost pipes which are straight and closed at their upper ends by screw caps. The several manifolds are provided in their adjacent sides with steam passages or ports g whereby the sections are placed in communication with each other.

H is the inlet pipe for live steam, connected with one of the end manifolds, and I is the inlet pipe for exhaust steam connected with the other end manifold. These inlet pipes preferably extend upwardly through the top of the casing A and are respectively connected with the boiler and the exhaust pipe of the engine. The steam inlet pipes are each provided outside of the casing with valves for controlling the passage of steam to the radiator.

J J J2 represent cut-off valvesarranged between the several sections and controlling the flow of steam from one section to the other. These valves each consist of a flat rectangular plate which slides horizontally in an open frame j secured between the adjacent sides of two manifolds. The latter are provided on their adjacent sides with tlat'bosses or slightly projecting seats j between which the frame j is clamped by tie rods k extending through the several sections. The frame j forms a valve chamber between two adjoining sections in which the valve plays and which communicates with the sections through the ports g, which latter are formed in the projecting seats near the outer ends of the manifolds.

Each valve is provided with a stem L which has its inner portion screw threaded and is free to turn in a horizontal opening or bearing Z formed in the outer portion of the frame j, while being held against lengthwise movement in the same by a collar Z secured to the stem and seated in an opening or cavity Z2 formed in the frame. The inner threaded portion of the valve stem is arranged in a smooth opening m formed longitudinally in the valve and is provided with a screw nut m which is seated in a vertical socket 'm2 intersecting the horizontal opening of the valve. This screw nut is held against turning upon the valve stem by the flat sides of the socket, so that upon turning the stem in either direction, the valve is caused to move inwardly or outwardly on the stem, thereby opening or closing the steam ports. Each valve stem passes outwardly through a stuffing box 'n arranged at the outer end of the valve frame and is provided with a hand wheel for turn- IOO ing it. The valve is attached to the stem by first placing the screw nut into the socket of the valve and then screwing the inner end of the valve stem into the nut from the outer end of the valve.

0 represents the drip pipes connected with the end manifolds and whereby the water of condensation is discharged. These drip pipes preferably enter the lower portion of the elbows of the steam inlet pipes H, I, as shown in the drawings.

Then the exhaust steam furnishes sufficient heat, without the use of live steam, the valve z' ot' the exhaust steam inlet I and all or several of the cut-off valves .I J J2 are opened and the Valve h of the live steam pipe H is closed, so as to allow the exhaust steam to pass into all of the sections, or as many ot' them as may be required to produce the desired result. In case the exhaust steam is insufficient to properly heat thebnilding, one or more of the sections nearest the live steam supply are cut off from the exhaust steam supply and live steam is admitted to these sections. For instance, if only enough exhaust steam is available to supply two sections the valve between the two central sections is closed, the other two valves are opened and,

exhaust steam is admitted to two sections and live steam to the other two sections. In this manner,live steam may be supplied to only one section and exhaust steam to the remain` ing sections, or, it desired, live steam alone may be admitted to all of the sections.

In a heating apparatus for warming build-` ings the radiator may thus be conveniently supplied with exhaust steam alone in mild weather, or with both exhaustand live steam in colder weather, or with live steam alone when the weather is verycold.

The cnt-off Valves are verysimple in construction, they form tight and reliable joints with the sides of the sections and as they occupy butta small space they permit of a very compact construction of the radiator.

The radiator represented in the drawings,

`consists of foursections, but it is obvious that lby indirect radiation but it is obvious that it may be used for direct radiation.

p represents the screw threaded sleeves whereby the ends of the heating pipes are secured to the manifolds. The ends of the heating pipes are provided with external screw threads and the sleeve is provided with an internal screw thread fitting upon the thread of the pipe and with a tapering external screw thread which enters a tapering threaded opening in the top of the manifold, so as to form a tight joint by wedging itself into the tapering opening of the manifold and against the outer side of the pipe.

I claim as my inventionl. The combination with a series of independent radiator sections provided with passages whereby adjacent sections communicate with each other, of valvesapplied to said passages, and inlet pipes for exhaust steam and live steam, connected with different radiator sections, substantially as set forth.

2. The combination with a` series of independent radiator sections provided with passages by which adjacent sectionsr communicate with each other, and valves applied to -said passages, of an inlet pipe for live steam connected with one of the end sections, and

`an inlet pipe for exhaust steam connected with the opposite end section, whereby the sections may be supplied with either live or exhaust steam, at desire, substantially as set forth.
