IMPRQVEM ENT lN STEAM-VALVES! Specification forming part of Letters Patent No. 1 59,019, dated January 26, 1875; application filed November 7, 1874.

To all whom it may concern: I

Be it known that I, J AMES ll. COREY, engineer, of the city of New York, in the county and State of New York, have invented a new and useful Improvement in Steamyalvcs, of which the following is a specification, reference being had to the accompanying drawings, in which Y Figure 1 is a sectional view of a globe and valve united, withone spindle running through and operating bot-h, thus showing my improvement.

Similar letters of reference indicale similar parts.

My invention relates to the construction of steam-valves, intended particularly for use on radiators forheating purposes; and consists in combining a supply and discharge valve, and operating both by a single spindle, so that by turning the latter it opens and closes the top and the bottom valve, the upper valve being for the introduction of steam or water, the lower valve for the discharge of condensation or waste water.

The ordinary custom on radiators or coils of heating-pipes is to have a valve at each end, one being for the admission of steam, the other to carry oli' the condensation. \Vhen two valves are so used, it becomes necessary, for the proper operation of the heating-pipes, to have the valves proportionately opened to each other. As they are generally operated by persons unaccustomed to their use, much trouble is experienced, both in the way of noise from the collection of water in the base, when the valves are not properly arranged, and from a loss of heat and waste of steam in having the purge too much opened, and allowing thestea-m to blow through without performing its proper heating functions.

In my valve, by one operation of the spindle, the parts must necessarily always be proportioned to each other-t-hc outlet to the inlet-and the proper opening always be prov ided for the condensation. The spindle has a waste to it, so as not to leave any water in the radiator.

economical and beneficial results must ensue. A is the'inlet for the steam. B is the passage for the steam to the radiator-pipes. O is the inlet-for the condensation'trom the radiator-pipes.' l) is the discharge for the waste packing, as shown in the drawings, and worked with one spindle.

There are many advantages, however, to its mechanical workings in having the valves attached to each other, as the expansion and contraction of the metals are more equal.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- The globe-valve for admitting steam or wa-.

ter, in combination with the discharge-valve, provided with inlet G and discharge D, both valves being operated by a single spindle, E, substaptially as and for the purpose set forth. In testimony whereof I have hereunto signed my name to this specification iu the presence of two subscribing witnesses.
