VALVE.
Specification of Letters Patent.
Patented Mar. 16, 1915.
I.application fixed apra 21,1914. serial No. 833,552.
To all whom 'it may concern Be it known that I, MAiURIoE FRANK HU'rcHIsoN, 'a citizen of the United States,
` residing at Herndon, countyof Fairfax, and
meet varying weather conditions.
State of Virginia, have invented certain new and useful vImprovements in Valves, of which the Vfollowing is a full, clear, and exact specification.
This invention relates to valves especially designed for use on steam, vapor, 'or other radiators for regulating or controlling the amount of heat emitted by each radiator to Such valves are used at the supply ends of the radiators so as to control the amount of steam or vapor admitted to them.
One object of the present invention is to provide a valve which may be used on any size of radiator. from the smallest to the largest, thus avoiding the necessity of lmaking and carrying in stock several sizes of 1 sired amount o steam or yvapor withinthe' ators as heretofore.
ofyalves to supply varioussizes. of radi- The present`valve has such a wide range of adjustments that it is capable of bein set for supplyingany dedlators.
YAnother object is to provide adjustable means for limiting the extent to )which the capacity of any of\the ordinary sizes of ra- .valve may be opened,`in order thatsaid valve may be used on the smaller sizes of radiators without danger of an oversupply of steam or vapor being admitted thereto. At the same time, when the maximum limit of supply has been fixed by said adjustable means the valve may be adjusted at will to any point between zero and said fixed ,maximum point in order to vary the amount of heat emitted from theradiator to meet weather conditions as previously mentioned.
The invention will be first hereinafter de-V 4is a detailed view ofthe valve proper removed from its casing.
The valve casing A has two passages B and C arranged at an anfrle to eachother and communicating by a stlot D in thepartition E within the casing. This partition yconstitutes part of the wall of the passage B which is tapered as illustrated in Fig. 2.
The valve proper F is cup-shaped and tapered to conform to the passage B in which it is snugly fitted. The stem G of the valve extends through the casing and is fitted with a handle H. A spring' K housed in a chamber'L in the outer portion of thecasing bears against the inner face of the handle and ytends to preserve the /snug fit ofthe valve proper in the passage B. In the wall of the valve proper there is formed 'a tapering slot M having diverging `edges extending around said valve.- One edge of the slot M is preferably arranged in the plane of one end of the slotv D, and the greatest width of said slot M is preferably equal to the length of said slot D. The slot M preferably extends almost entirely around the valve proper as clearly illustrated in Fig. 4, in order topermit of a wide scope of adjustment.
Arranged concentrically around the stem of the valve is a circular scale P which is provided with a fixed stop Q and an adjustable stop R, the latter/consisting of a bolt adapted to be clamped at any desired point in either one of two arcuate slots S extending. almost entirely around the scale as .shown in Fig. 3. The handle H carries a finger or pointer T which is arranged op- Y posite the zero point onthe scale when in contact with the fixed stop.
In operation the movable stop R is adjusted on the scale opposite the point thereon which indicates the maximum capacity of the radiator to which the valve is applied. Thus if the maximum capacity of the radiator is 35 feet radiating Surface, the movable stop R is clamped at the point illustrated in Fig. 3, so as to limit the movement of the handle to the arc `between the fixed' stop Q and said movable stop R which in this case covers 35 points 4'on the scale. There is, therefore, no danger of the valve being opened too far, that is, so as to admit more steam or vapor to the radiator than its capacity justifies. It will be understood, of course, that when the finger T is at zero,
the slot D is entirely closed by the valve proper, thatvis to say b'y the uncut portion of the latter between the small and large ends of the slot M, which as illustrated 1n Fig. 4, is preferably equal tothe width of said slot D. As the valve proper is turned by means of the handle so as to cause the pointer to move around 'the scale from the Iixed stop toward the movable stop, an in- Acreasing proportion of the slot,A D is uncovered or opened, whereas movement of the valve in the opposite direction has the effect of gradually closing the yslot D.l It will thus be seen that while the valve may be regulated in advance to corres vond to the capacity of any size radiator, said valve ,may afterward be turned oil' or on to any desired extent between they limits thus fixed for heating different proportions of the entire radiating surface of the radiator, and that such' limited regulation may be eiected just as readil ixed limits in both directions.
The scale indicating the capacity or length ofu radiating surface of radiators'on which the'valve may be used is intended to apply to a standard pressure, as two` ounces. When used with a heating system having a di'erent pressure, allowance for such difference can easily be made in setting/the valve with respect to the scale. For instance, if there is a pressure of four ounces, 4and the radiator has la capacity of 40, the
valve would be'setiat 20.
It will bef noted that a slight space U 1s left between the top of the valve'F and the partition V in the casing` through'which the valve stem G extends. A slight space W is also left between the scale plate P and the pointer T. These-spaces permit the valve to be pressed down against the influence of the spring K to a slight extent for loosening said-valve in case it'becomes stuck b reason of corrosion or other cause. A was er X is placed around lthe valvev stem. above the spring'and fittedv in the upper end of the as in an ordinary valve havingchamber L to protect the spring and guide the valve stem.
Having thus described my invention, what .I claim as new and desire to secure by Letters Patent of the United States is:
1. The combination with a casing having branch passages and a rectangular slot through which they communicate, of a valve.
through which they communicate, of a valve having a tapering slot movable across the slot in the casing for varying the uncovered portion of the latter slot, a scale on the cas ing, a pointer attached to the valve and cooperatingwith the vscale for indicating the position of the slot in the valve with respect to the slot in the' casing, a fixed stop on the scale for. engaging the pointer when the slot in the casing is closed, and an adjustable stop on the scale also adapted to be engaged by the pointer for limiting the opening of said 'slot in the casing beyond a predetermined extent.
" 3. The combination with a casing" having branch passa es of a valve fitted in one passage-and aving a uniformly gradual substantially unbroken spiral ed e arranged obliquely with respect to the ot er passage and extending from the lowest to the highest level thereof, and means for turning the valve to move its spiral edge across the latter passage, thereby uniformly varying the uncovered portion of said passage.
In testimony whereof I have signed my name to this specification in the presence of two attesting witnesses.
