JOHN H. BEAGHER, OFgPHILADELPHIA, PENNSYLVANIA... Lam Patent o. 67,840, dated August 20, 1867.

IMPROVED VALVE I'OR GAS-GENERATORS.

TO ALL WHOM IT MAY GONCERNi.

Be it known that I, JOHN H. BEACHEB, of Philadelphia, Pennsylvania, havelinv'ented an improvement in Gas-Generators; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention consists of a valved regulator,gcons tructed and operating in combination with and forming a part of a gas-generator, as fully described hereafter," so that the gas supplied to the burners maybe maintained at an even and uniform pressure.

In order to enable othersv skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part e f-this Specification, and in' which Figure 1 is a sectional view of a regulator applied to a gas apparatus, a portion of the latter being shown in red lines. i i

Figure 2, the same with the working parts in a different position.

Figure 3' is a; sectional plan view.

Figure 4 an enlarged perspective view of the valve of the regulator, partly in section, and

Figure 5 a diagram showing the regulator attached to a gas apparatus, Similar letters refer to similar parts throughout the several views.

A is a vessel which is open at the top, and in which slides verticallya smaller vessel or receiver, D, open at the bottom, and having at the sides guide-pulley a a. Through the bottom of the vessel A pass pipes B O, and in the upper end of tbeformer fits a valve, 0, which is connected to and controlled by a. weightedlever, d, achain,f, being connected at one end to the lever, and at the other toa rod, e, which passes through a stuflingbox at the top of the receiver. The valve 0 consists of two rigid'disks containing between them a leather washer, and is so arranged that it will be closed when the receiver is elevated, and opened as the receiver descends. i X is a. hollow metal cylinder, (shown by red lines, fig. 1,) and'is divided into chambers,- y 12, the former containing k a pump by which air is forced through the tube .Binto the receiver D, the latter containing a series of fibrous strands saturated with gasoline. The vessel Ajs'half filled with water or other suitable fluid,"so that the air which passes from the chamber can escape from the receiver only through the pipe. C, from which it passes into the chamber a; and among the saturated strands to the burners, the receiver being elevated as the air passes into the same, and the extent of this elevation being in proportion to the rapidity with which the .air is dischargedfrom the pump. In the ordinary gas apparatus a regulator without any valve is used, and as the operation of the pump is very irregular, the quantity of air passing into the receiverI) is sometimes greater than at others, the receiver being alternately elevated and deprcssed, so that the pi'essurewithin the pipes, and consequently the size of the flame, constantly vary. V By the application of a valved regulator to a gas appas -ratus the difficulty abovealluded to is effectually overcome, as the instant the receiver is elevated (in consequence of an increase in the supply of air furnished by the pump,) the valve 0 is partly closed, so that no greater volume of air can pass into the receiver than at first, while the air confined (under a constantly-increasing pressure) in the pump tends to retard the operation of the latter; In like manner, any interruption of the usual speed of the pump will be followed by a reduction of the-pressure within the receiver, and by the descent of the latter. the valve will thus be opened to'such an extent that the required quantity of air can pass into the regulator and to the burners.,

I wish it to be understood that I do not. claim the within-described regulator ofitself, as it is in many respects similar .to gas-regulating devices heretofore used, but I claim as my invention, and desire to secure by Letters Patenti p 1. A valved regulator constructed and operating substantially as set forth, in comhinationwith and forming a part of ages-generating apparatus as specified.

2. The throttle-valve composed of two disks with intervening strips of leather, as set forth.

In testimony'whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
