IMPROVEMENT IN GAs- EeuLA'roRs.

Specification forming partof Letters Patent No. 173,556, dated February 15, 1876; application i'il'e I I January 15, 1876. g

the current of passing gas, for the purpose of reducing the pressure and flow thereof. Figure] is a longitudinal sectional elevation of my improved regulator taken on line a: w of Fig.2. I Fig. 2 is a horizontal section.

Similar letters of reference indicate corresponding parts.

The regulator or governor'consists of a hollow case, A, with agas-inlet, B, and outlet G,

and containing a hinged or pivoted weight or gate, D, operating as a valve between the inlet and'outlet, so'arranged that the gas must raise and bear its weight in passing fronrthe inlet to the outlet. E represents a partition ,in the chamber, ppon which the gate hinges,

and which, in conjunction with the gate, divides the chamber A into-ad and a ,a 'connect'- ing and opening freely into the pipe leading to the burners, and a into the pipe connect ipg with and leading from the source of supply, the purpose being that when in operation the pressure at the exitwould be equal to that at the entrance, minus the weight or pressure of the gate.

In practice, it would probably be desirable to have an adjustable counterbalance or counterweight for adjusting and steadying the gate. It is scarcely probable thata more gate wouldoperate with ,suflicient steadiness to allow the flow of gas to pass smoothly, and

without receiving from the gate a vibratory or wavering motion that would be injurious, and perhaps. fatal to its use, whereas a gate weighing, say, .ten ounces, and counterbalanced to the extent of nine ounces, wouldrise with a pressure of one ounce, and remain steadily suspended so long as the pressure was kept'up, so that with a pressure from the incoming gas equal to two ouncps, and on the outgoing gas equal to one ounce, the gate would remain open, and pass whatever amount of gas was necessary to keep up the pressures; but when the pressure on the outgoing gas would be above one ounce the gate would close and remain closed until the difference between'the two pressures would equal the weight of the gate.

When twoor more burners are tobe supplied by the gas flowing through the regulator. the flow necessarily requires to bemore rapid than it but one burner is to be supplied;

" but it is desirable to increase the pressure of the gate in proportion to the rapidity of flow,

and this is accomplished by the manner of hinging and arranging it, for the more nearly it approaches a horizontal position, the more it is affected by the operation of gravity.

. -It is obvious that the most of the forms of counter-balance will operate with increased power as the gate approaches a horizontal position, and that the center of gravity of the gate and of its counter-balance can be readily so arranged that the pressure of the gate will be less and less as it opens wider and wider, and that in this way allowance can be made for increase of friction (and consequent decreaseof pressure) consequent upon the increased flow of gas.

I do not claim, broadly, a pivoted weighted valve or gate for regulating the flow of gas; but, Having thus described my invention, -I claim'as new and desire to secure by Letters Patent- The gate D, hinged to the partition E within the chamber 'A, and covering the inductionpassage 91?, as shown and described, whereby the gate or valveis opened more or less widely as the flow of gas is more or less rapid.
