RADIATOR-VALVE DEVICE.

SPECIFICATION forming part of Letters Patent No. 479,400, dated July 26, 1892.

Application filed April 21, 1891.

To aZZ whom it may concern:

Be it known that 1, JOHN COLLIS, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a new and useful Improvement in Radiator-Valve Devices, of which the following is a specification.

My invention relates to an improvement in the class of valve devices employed at the radiators of steam-heating systems to enable cutting off the supply of steam at any radiator provided with the device without thereby obstructing the circulation in the steampipes. As the valve device in the class referred to has hitherto been constructed, while provision is made that by turning the valve to shut off the steam-supply to the radiator there shall be a short circuit produced for the steam between its inlet and outlet pipes outside the radiator, the construction is such as to close the short circuit when the valve is turned to open the radiator to the steam-sup ply. This construction has the disadvantage I that it affords no means for enabling the condensed steam in the supply to separate therefrom, but requires it to be carried in the supply to the return-pipe through the radiator, wherein much of the condensation is liable to be lodged.

My object is to provide a construction of valve device in the aforesaid class whereby there shall always be an opening in the passage between the steam inlet and return pipes whether the valve shall be closed to shut ofi the supply to the radiator or open to admit it thereto. Thus when the valve is open I am enabled to provide for separation from the steam-supply before it enters the radiator of the condensation, which is short-circuited into the return-pipe, and thereby the radiator is supplied with the more-dry steam.

My improvement not only permits the circulation to continue unobstructedly through the pipe system in case of closing any number of the radiator-valves in the steam-circuit, but it particularly adapts the steampipes to be laid horizontally throughout the building behind the base-boards of the walls, and the valve-containing branch pipes therefrom to the radiators to be short, according to the short distance of the radiators from the walls, by leading by the most direct course $eria1No. 389,801. (No model.)

into the radiators. The pipes may also be laid in front of the base-board and the connections made with elbows or swing-joints, and all possible expansion of the supply and waste pipesmay be looked after without raising the radiator-feet from the floor.

In the accompanying drawings, Figure 1 is a view in broken side elevation representing a loop radiator in operative position with my improved valve device in place in the steamcirculating system of the kind involving supply and return pipes. Fig. 2 is a section taken on the line 2 of Fig. 1 and viewed in the vdirection of the arrows. .Fig. 3 is a View showing my improved valve device in elevation as connected in a circulating system having a single pipe for both the supply to and exhaust from the radiators. Fig. i is an enlarged vertical sectional view of the valve, taken on the line i of Fig. 3 and viewed in the direction of the arrow. Fig. 5 is a similar view of the same, taken on the line 5 of Fig. 1 and viewed in the direction of the arrow. Fig. 6 is a plan sectional view of the same, taken on the line 6 of Fig. 3 and viewed in the direction of the arrow.

A is my improved valve device of the socalled corner-valve variety, and the construction of which renders it a three-way gate-valve. It involves the following described details in its construction: The shell 0, which should be of the general cylindrical form illustrated,is provided near its base with an opening q, the diameter of which is preferably about three-quarters of an inch, and over the opening q with a somewhat-larger opening 19, both said openings having nipple extensions, as shown, at which to connect the pipes, as hereinafter described. Near the base of the shell 4" at a right-angle to the opening q is an opening 0, having cast in it a short tube 0', adapted to be connected at its outer end with the inlet-opening to a radiator B, and projecting at its opposite end into the shell, where it alfords a valve-seat n. Centrally behind the valve-seat n in the shell 0" is a vertical web on, inclining from its upper end toward the base of the opening 0, and affording a guide for the valve 0. The pre ferred form of the valve 0 is that of a block having a straight flat face provided with a circular seat Z for a packing-ring Z, and tapering in a downward direction at its rear side, as shown at a: in Fig. 4, to conform to the opposite taper of the rib m, which fits into a longitudinal recess Z Fig. 6, in the back of the valve. When the valve 0 is in its closed position, (illustrated,) the packing ringl bears against the seat n.- For raising and lowering the valve 0,1 provide a rotary threaded stem 0, engaging a corresponding hole in the valve, and provided with a collar 70, seated in a recess in a head 2', screwed into the upper end of the shell, an internally and externally threaded ring 1; being screwed into the shell upon the head and aifording a bearing for the threaded end of the head h, which confines the stem 0 at its collar against longitudinal movement and through which the stem passes, being surrounded at the outer end of the head it with a suitable stutfing-box g.

With steam supply and return pipes f and e, arranged as shown in Figs. 1 and 2, my improved device A is applied by connecting it at its opening 0 with the radiator B, and by branch pipes f and 6, respectively, with the pipes f and e. If, as indicated in Fig. 3, only a steam-pipe f be provided both for the supply to and exhaust from the radiator, both branch pipes f and e may be connected with it, as represented.

When the valve 0 is raised, and thus removed from its seat n, to open the passage 0, the steam, which is always free to enter the valve device A at its opening 19, may pass into the radiator by way of the opening 0, and the condensation may pass out at the lowermost openingq into the pipe e,if provided, or into the pipe f if only the latter be provided. Lowering the valve C to the position of covering the seat n eltectnally prevents steam entering the chamber of the device A at the inlet 1) from gaining access to the radiator, but does not interfere with the steam-circulation through the valve device from the inlet p to the outlet q, since the latter is always accessible along the sides of the valve 0, which does not diametrically fill the shell 0'.

It will thus be quite apparent that'shutting off the steam-supply to a radiator or to any number of radiators in a steam-heating system not only does not afiect the steam-circulation but does not necessitate conducting the condensation into the radiator, because the directly into the branch passage for the steam from the inlet to the outlet opening of each valve device A is not thereby closed.

The lower opening q may be provided in the base of the shell with advantage, particularly where a radiator is in the center of a room or around a column.

WVhat I claim as new, and desire to secure by Letters Patent, is- 1 1. In a radiator-valve device, a shell having an outlet-opening at which to connect the device with aradiator and a supply-opening and a discharge-openin g in vertical line with each other to one side of the outlet-opening at which to connect the device with the circulatingpipe system, said supply and discharge openings having permanent open communication with each other in the shell past the said outlet-opening, in combination with a verticallyadjusta-ble valve confined in the shell with relation to its outlet-opening and provided with means for operating it to open and close the said opening, substantially as described.

2. A three-way-valve device for use with a radiator and its circulating-pipe system, comprising a shell having an outlet-opening 0, a a

tube cast therein adapted to be connected at its outer end with the inlet-opening of a radiator and projecting at its other end within the shell to form a valve-seat n, a supplyopening 19 and a discharge-opening q, respectively, above and below the plane of the outletopening to one side of the latter and having branches f and 2' connecting them with the circulating-pipe system, and a vertically-adjustable valve C, confined in the shell with relation to the said outlet-opening and provided with means for raising and lowering it to open and close the openingo, the openings 19 and q having permanent direct communication with each other, whereby when the valve is closed the circulation is continued between the said branches and whereby when the valve is open condensation in the steamsupply from the branch pipe f discharges pipe e, substantially as described.
