VALVE MECHANISM FOR GAS.

To all whom it may concern:

Be it known that I, CARL H. MIpLnR, citizen of the United States, residing at Cleveland, in 'the'county of 'Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valve Mechanism for.

Gas, of which the following is a specification.

' My invention relates to improvements in valves to control the flow of gases or fluid under pressure but especially gas'as is used with burners, and the invention consists in a valve mechanism adapted to equalize or proportion the flow at the orifice to the vol ume or quantity of gas admitted past the valve therein, all substantially as shown anddescribed and particularly pointed out in theclaims.- In the accompanying drawings, Figure 1 is a side elevation of-the'device partially sectioned in its connections, and Fig. 2 is a longitudinal sectional-elevation of the body member and associated parts. p

In valve mechanism to supply gas to a -burner, say such as is used in a kitchen range, it is important that at leasttvvo common objections or. defects be avolded,

namely, the blowing and the sputtering ofthe gas. Both of these conditions are highly objectionable in sucha connection'as well asin all others wherein it occurs, and the object of this invention is to prevent such results or rather to provide a construction wherein they cannot occur.

Thus, in the drawing, .13 represents the body of-the valve having alongitudinal bore for the valve-stem 0 considered as a whole.

and a fluid inlet 2' at one side to said bore. The saidbore is differential or. of two diameters or sizes in cross section, the larger por-, tion extending through from the one end across said inlet to valve vseat 3, and the smaller portion extends from said valve seat tothe other end of'the said bore and which is its orifice-or discharge end. Now,- having a body B of this construction or substantially as shown and described for practical purposes, I employ a valve'stem C which. also maybe said to be of difi'erent sizes in ts cross sections corresponding to said bore: iid

' provided with av thread 4 on'its larger-porand having on stem 5 at the entrance to"said smaller Patented Dec.5,4 1911. Application 'filed January 14,1910. Serial No. 538,158.

bore and adapted'to occupy said valve seat 3,

-and the extremity or point .7of the said stem projects out beyond the end of body B relatively as shown. This projection is however only incidental, in a sense, because of a reducing plug 9 inserted in sald body, or

screwed into the .threadtherein at this end and projecting outward beyond the said end of the body a sufficient distance to obtain the desired control of the gas at this point. This control is relative and is designed to be pro portional tothe position ofvalve 8. For example, and as a matter of experience, -I should explain here that the sputteringrof the gas at the orifice and the blowing which always is objectionable is designed to be partially controlled by the adjustments which plug 9 afi'ords. It will be noticed that said plug'has a bore for the reduced portion 6 of the v'alve stem which gradually tapers inwardto its orifice and so that as the said plug is adjusted it may more or less closely approach to the tapered point 7. It is not intended that said orifice shall ever be wholly-closed because point 7 is not a valve but a passage reducing member working in conj'unct-ion with the said plug 9, and the object is to proportion the issue of the gas past or about said point to the volume ad mitted past valve 8? I have foundthat if what may be termed-uniformity of issue or pressure be maintained at these two points proper adjustment to begin with there is no blowing and no sputtering however 'much or little gas is used. Hence if a full head of gas be used the orifice at.

point 7 is opened correspondingly wide by withdrawing the valve stem. Then as the quantity used is to .be reduced the said stem is turned inward wh' h will cause point? to enter the'said or fice' more or less and correspondingly reducethe volume of the outflow. But the proportions with the gas admitted will be maintained and there will be only a gradual reduction of the flame and nothing more,--and in no case does. reducing point 7 wholly close the orifice.

e In theprese'nt instance I have shown this range or stove-asv indicated b part D, but it may be used wherever it is ound useful.

.It will be'seen from the foregoing that the discharge orifice for the as is under positive' control by'means of t e valve stem and device in connection presumably with a is reduced but never entirely closed with the shutting down of the gas and enlarged as the valve is opened. The area of said discharge orifice is therefore always changing with the valve and dependent thereon, and plug 9 is i set according to 'conditions'of the gas flow and need not be changed unless conditions .of operations change, such as more or less gas pressure or possibly according as to 4 whether artificial gas be used. 10 WhatIclaimis: 1. In gas feeding mechanism for cooking ranges and the like, a bo'dyhaving a-bore *oftwo diameters through its center and a valve seat where said diameters change andan inlet for gas 1n advance of said seat, a

' plug with a tapered orifice adjustable in the outer end of said bore, in combination with a hand controlled valve stem having a valve adapted to engage said seat and shut ofi the flow of gas and provided withta spindle projecting through the smaller portion of said bore from said valve and having a tapered reducing point entering the said -tapered orifice and limited to a partial closing of said orifice.

2. In' valve mechanism adapted to control the .flow of gas, a body having a bore of two sizes and a valve seat at the point where said here changes :in size from its larger to its smaller diameter, a tubular reducing plug fixed in the outer portion of said smaller bore provided with an orifice of gradually reduced 'cross section from its inner to its outer porclosed. e

In testimony whereof I afiix my signa-' ture in presence of two witnesses.
