RADIATOR-VALVE.

SPECIFICATION forming part of Letters Patent No. 757,087, dated April 12, 1904.

Application filed April 14, 1903.

To a/Z/ whom, t may concern:

Be itknown that I, ADoLrHUs L. Bowne, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Radiator-Valves, of which the following is a specification.

This invention relates to valve attachments wherein communication between the radiatorn hot-water systems and could not be employed` in connection with steam-radiator systems.

The present invention has 1n view a single valve, which is equally useful for steam and hot-water systems, and can be readily converted from one use to the other.

A further object of the invention is to provide a construction of radiator-valve involving novel and eective means for draining back or returning water of condensation in such a manner as not to oppose the steam, besides maintaining ,a most effective circulation to insure the ready and uniform heating of the radiator.

With theseand many other objects in view, which will more readily appear as the nature of the invention is better understood, the saine consists in the novel construction, combination, and arrangement of parts, which will hereinafter be more fully described, illustrated, and claimed.

The essential features of the invention involved in the novel arrangement of the valveseat and the means employed for converting the valve from one use vto the other are susceptible to structural variations without departing from the scope of the invention; but

Serial No. 152,497. (No model.)

a preferred embodiment thereof is shown in the accompanying drawings, in which- Figure l is an elevation of a portion of a jradiator of the steam or hot-water type, showing attached thereto a convertible valve embodying the present invention. Fig. 2 is an enlarged sectional view of the valve, showing the same open with the parts arranged for use with a steam-heating system. L ike reference numerals designate corresponding parts throughout both figures of the drawings.

In carrying out the invention no change is involved in the construction of the radiator or in the pipe connections, so for illustrative purposes there is shown in the drawings a few sections of a radiator, (designated bythe numeral 1,) and which radiator may be of any approved type, such as employed with eithersteam or hot-water heating systems wherein communication between the radiator and boiler is controlled through the medium of a single valve. The single-valve controlling device constitutes thepresentinvention and is of peculiar construction, as shown in the drawings.

Referring particularly to the drawings., the numeral 2 designates the valve-casing as an entirety, and this casing is designed to have the usual pipe connections therewith-namely, a vsupply-nipple connection 3 with the lower end of the iirst radiator-section and a rfeed-pipe connection 4 with the boiler or pipe system connected with the boiler. To provide for proper coupling with the nipple and pipe connections 3 and 4, the valve-casing 2 is formed with the right-angularly related inlet and outlet necks 5 and 6, which are respectively connected with the pipes 4 and 3 and are dis-v posed in planes atV right angles to each other. When the valve attachment is in its applied position, the inlet-neck 5 usually stands in a vertical plane, while the outlet-neck 6 is disposed at the side of the casing-body and lies in a horizontal plane.

In addition to the right-angularly related inlet and outlet necks 5 and 6 the casing-body 2 is formed with an upstanding valve-chamber 7, projecting above the planes of both of the necks and disposed obliquely thereto. In

the preferable construction the inclined upstanding valve-chamber is disposed at an obtuse angle to the inlet-neck 5 and at an acute angle to the outlet-neck 6, and the same is designed to accommodate therein the imperforate cut-0H valve-disk 8, carried by the inner end of the valve-stem 9, adjustably mounted in any approved way and extending through the stuiing-box cap 10, fitted over the outer end of the valve-chamber 7, said stem 9 carrying upon its outer end exterior to the valvechamber the usual operating hand-wheel 11.

By reason of the disposition of the inclined oroblique valve-chamber 7 the valve-stem 9 is held to work in an inclined plane and the interior cut-off valve-disk 8 playsover the interior inclined valve-seat 12.

The valve-seat 12 is produced by an integral annular flange formed within the body of the casing at the inner end of the inlet-neck 5 and forms thereabout an annular drain-gutter 13, the lowest point 14 of which is disposed the greatest distance from the outletneck 6 and lies in a plane below the horizontal plane of such outlet-neck. It will be observed that the flange-like valve-seat 12 lies in a plane at right angles to the plane of movement of the cut-off valve, and hence is set oblique to the planes of both the inlet and the outlet necks and at the highest point in the gutter 13, surrounding the valve-seat, and hence at a point nearest to the valve-neck 6 the valveseat web of the valve-casing is provided with an auxiliary heating-vent 15, adapted to be temporarily closed by a closure-plug 16, usually in the form of an ordinary headed screw, which is readily accessible for removing and replacing through the inlet-neck 5.

When the valve is employed in connection with a steam-radiator, the vent 15 is closed by the plug or screw 16, and by reason of the peculiar disposition of the valve-seat 12 and the drain-gutter 13 it will be observed that the steam is caused to enter the valve-casing in such a way as to move ltoward the top thereof before being defiected into the radiator, and hence entirely out of contact with the water of condensation, which may be returned into the valve-casing. Such water passes from the lower side of the outlet-neck 6 into the annular gutter 13 and overfiows from the lowermost point 14 of such gutter over the lowcrmost edge of the valve-seat 12 and thence back into the pipe i through the neck 5.

When the valve is employed in connection with a hotwater heating system, it is .only necessary to remove the plug or screw 16, so that when the cut-olf valve 8 is closed on its seat a sufficient circulation of hot Water will be maintained through the auxiliary vent 15 to provide for keeping the water warm in the nipple connection leading from the valve-casing to the radiator.

From the foregoing it is thought that the construction, use, and many advantages of the herein-described radiator-valve will be readily apparent without further description, and it will be also understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-

A combined hot-water and steam-radiator valve comprising a valve-casing having angularly-related inlet and outlet necks and provided at the inner end of the inlet-neck with an inclined valve-seat flange set oblique to the planes of both of said necks, and forming thereabout an angular drain-gutter, the lowest point of which gutter is below the plane of the inner side of the outlet-neck, said valvecasing being further provided with an auxiliary heating-vent piercing the valve-seat web in the highest point of the gutter at one side of the face of the valve-seatat a point near to the outlet-neck, a temporary removable closure-plug fitted in said vent and exposed for manipulation through the inlet-neck, and a cut-off valve-disk arranged over the oblique valve-seat.

In testimony whereof I affix my signature in presence of two witnesses.
