Specification of Letters Patent.

Patented July 6, 1909.

Application filed March 21, 1906. Serial No. 307,260.

To all whom it may concern:

Be it known that I, FREDERICK GLAss, a citizen of the United States, residing at Kingston, in the county of Ulster and State of New York, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valves such. as are particularly intended for use'in connection with steam for hot water radiators, although i the valve of the present invention may-be adapted for use in other connections.

In placing radiators difficulty is often experienced in properly connecting them with their steam or hot water supply pipes. This is due to the fact that the valves or connecting devices usually employed, require that the radiator be placed a certain exact dis- If the radiator be too near or too far it is necessary to work the same into position before it can be connected properly with the supply pipe, and as the radiators are usually heavy, two or more men are required for placing them in position.

. The object of the present invention is to improve the construction of radiator valves in such manner as to render them adjustable, so that if the radiator has been placed a trifle too near or a trifle too far from the supply pipe, the proper connections can be made without the necessity of moving the heavy radiator.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and clainiied as a practical embodiment thereof.

In the accompanying drawing forming part of this specification; Figure 1 is a side elevation of a valve constructed in accordance with the present invention, a portion of the radiator being shown in. section. Fig. 2 is a vertical section, partly in elevation, taken through the construction shown in llig. 1. Fig. 3 is a detail view of the packing ring.

Like-reference numerals indicate corresponding parts in the different figures of the drawing. a p

The reference numeral 1 indicates an ordinary valve casing which is screwed or otherwise suitabl secured to a supply pipe 2. Located in t e casing 1 is a rotatable sleeve 3 having an opening 4 to control the passage of fluid through the valve. hen the sleeve 3 is turned so that the opening 4 registers witluthe end of a lateral branch or tubular extension 5 formed on the valve casing 1, the valve is open,,anil when said sleeve 3 is turned so that the opening 4 is out of register'with the tubularextension 5, the valve is closed, as will be readily understood. The sleeve 3 is operated by means of a stem 6 which extends through the head 7 of the valve casing and is provided with a handle 8.

Any suitable packing 10 held in position by a screw cap 11 is employed for rendering the valve steam tight.

The parts thus far described are old and well known in the art, for which reason they are not specifically claimed herein.

In carrying out the present invention a tube 12 is adpistably and rotatably fitted V into the tubu ar extension 5 of the valve. The tube 12 is threaded'at the end 13 thereof so that it can be screwed into the radiator, a portion of which. is indicated at 14. The tube 12 is also formed with an octagonal or other suitable collar 15 adapted to receive a wrench for use in screwing the tube 12 into the radiator. If desired, the tube12 can be screwed into the radiator to such an extent as to seat the flange 15 against the outer surface of the radiator so as to prevent leakage through the joint.

Loosely surrounding the tube 12 1s a col lar 17 which preferably is triangular in 'cross section. The collar 17 is intended to be forced up against the internally coned end 18 of the extension 5 by means of a collar 19 which is contracted at the end 20 so as to fit closely around the tube 12, and is enlarged at the end 21 so as to fit around the end ofthe extension 5 and to be suitably secured thereto by means of screw threads or the-like. A

collar 19 is then screwed on to the exten-- sion 5 and tightened so as to force the triangular collar 17 against the internallyconed end 1 of the extension 5, whereby said collar 1 7 is tightly jammed or pressed around the tube 12, thus forming a perfectly tight joint between the tube 12 and extension 5.

Having thus described the invention what is claimed as new is A cylindrical valve having open threaded ends and a smooth internal surface and also having a laterallyrojecting cylindrical extension of uniform ore throughout its length and provided with a smooth internal surface, said extension having its outer end undercut to form an internal bevel, an external thread on the outer end of the extension adjacent the bevel thereof, a cylindrical tube having a portion of uniform external diameter snugly fitting in the said extension for sliding contact therewith and capable of longitudinal adjustment throughout the length of the extension, an external thread on the end of the tube opposite from that dis osed in the extension, the threaded end of said tube being adapted to be screwed into a fixed structure, a non-circular flange on the tube forming an annular shoulder at the inner end of the external thread of the tube, a removable hollow cylindrical valve rotatably mounted in the casing and snugly fitting therein and having a portin its side adapted to communicate with the extension, said-tube being capable of entering the casing when the valve is removed and the non-circular flange serving to limit the screwing of the tubeinto the said structure, a packing ring bearing a ainst the bevel of the extension, a nutthretu ed on the extension and engaging the packing ring to compress the same into contact with the tube and frictionally holding the valve casing and tube together, a pipe threadedin the valve casing at one end, a cap threaded on the casing at the opposite end and cooperat ing with the said pipe for preventing longitudinal movement of the valve, and a valve stem secured to the valve and extending through the said cap.

In testimony whereof, I have aflixed my
